[[foldercontrol]]

[[folder:In General]]
* EleventhHourSuperpower: [[spoiler:In the series finale the entire Hamato Clan is taught to unlock their ancestral power of Hamato Ninpo by drawing upon their familial love. This drastically closes the gap between them and Shredder]].
* AccentsArentHereditary: While Splinter has a clear Japanese accent, none of the turtles have this accent. [[spoiler:Justified in that the turtles grew up in New York and Splinter is actually from Japan.]]
* AdaptationalBadass: Though they are [[AdaptationalWimp less experienced than some of their other versions]], they also possess actual superpowers thanks to their mystic weapons that allow them to perform feats that their counterparts could only dream of. You're probably not going to see any other version of Leonardo redirecting enemy attacks [[ThinkingUpPortals by spamming portals]] or Michelangelo ''hurling a giant tanker'' for instance. Also, with the exception of the 2003 series where Leonardo was able to defeat Splinter during some rage-fueled sparring in the later fourth season, most versions of the Ninja Turtles are shown to be outclassed by Splinter to varying degrees in fights. In ''Rise'', after undergoing some serious training, the Turtles are able to take down Splinter during a practice session ''towards the end of just the first season alone''.
** Donatello's technological capabilities are a big example of this, given that his inventions not only work properly for the most part, but his Bo staff has multiple settings rather than being made out of wood.
* AdaptationalComicRelief: Less serious than most of the modern versions of the characters.
* AdaptationalNiceGuy: At least when it comes to their relationships with each other. Make no mistake, the turtles in all incarnations care about each other, but they also tend to be ''very'' prone to squabbling and infighting, to the point they can come off as not really respecting each other; Leo and Raph have it worst, constantly butting heads and barely tolerating each other. In Rise, while they rib each other often and drive each other up the wall to varying degrees, the brothers have a much more affectionate family dynamic. They compliment each other's skills, are willing to help each other out if needed, and hug and/or say they love each other (genuinely, not in a joking or mocking way) ''countless'' times.
* AdaptationalWimp: In this version the turtles don't have years of ninjitsu training under their belts, as Splinter was less willing to train them, so they are less skilled in certain areas. This begins to change after Splinter finally begins training them seriously.
* AdaptationPersonalityChange: Possibly the most divergent iteration of the Turtles to date, as each of them breaks away from the "standard" version of their character in a major way:
** Splinter: In past series, Splinter has been the [[OlderAndWiser wise]], [[TheStoic serious]] OldMaster who taught the Turtles in the traditional ways of ninjutsu. In ''Rise'', he's instead a [[LazyBum lazy]] GrumpyOldMan who mostly lets his sons do what they want rather than pushing them into training, [[spoiler: instead dwelling on his GloryDays as Lou Jitsu; he's unfamiliar with the Hamato traditions himself, having [[YourTraditionIsNotMine rejected them]] after following them led to him growing up without his mother.]] Arguably, the changes to Splinter could be seen as [[ForWantOfANail informing the changes to the Turtles]].
** Raphael: Typically, Raphael is a [[{{Angst}} sullen,]] [[RebelliousSpirit rebellious]], HotBlooded JerkWithAHeartOfGold who [[SiblingRivalry clashes with Leo]] over the latter's position as leader. In ''Rise'', Raph ''is'' the leader who feels responsible for his siblings as the [[BigBrotherInstinct big brother]], and often acts as the OnlySaneMan when the others are goofing off; he's also [[EmotionalBruiser much more open about his emotions]] than Raph usually is.
** Leonardo: In past series Leonardo is TheLeader and the one who's [[TheChainsOfCommanding most dedicated to his role]], often focusing on training and taking responsibility at his own expense. In ''Rise'', where there's no pressure from Splinter to lead his siblings and live up to the ninja traditions, he's a BrilliantButLazy slacker and jokester; while he's still TheAce it's more of a matter of [[HardWorkHardlyWorks natural talent]], as he's unwilling to put in the effort to train.
** Donatello: Normally, Donatello is a NiceGuy and something of a ShrinkingViolet who's content to support his brothers as the one who "does machines". ''Rise'' Donnie is instead a [[LargeHam flamboyant]] InsufferableGenius and ControlFreak who's obsessed with being the center of attention, which stems from [[InferioritySuperiorityComplex a desire for validation]] and a belief that people only like him because his tech is useful.
** Michelangelo: Typically Michelangelo is the [[FunPersonified relentlessly silly]] AnnoyingYoungerSibling and {{cloudcuckoolander}} of the brothers. In ''Rise'', Mikey is the closest of his siblings to their classic portrayals, but with the other characters taking on AdaptationalComicRelief traits much more emphasis is put on his artistic talents and status as an AllLovingHero.
** April: Traditionally, April is the UnfazedEveryman who usually stays out of the action and [[WomenAreWiser acts as the voice of reason]]. Here -- partially thanks to being a CompositeCharacter with Casey Jones -- she's a [[BatterUp baseball bat-wielding]], HotBlooded ActionGirl who [[WhyDoYouKeepChangingJobs can't hold down a job]].
* AdaptationRelationshipOverhaul:
** In general, the Hamato Clan generally had more of a student and master bond in prior adaptations, with the Turtles generally referring to Splinter as "master" or "sensei", albeit still with a familial overtone with Splinter referring to them as his sons. In ''Rise'', the Hamato Clan consider each other a family first and a ninja group second, with the Turtles often openly referring to Splinter as their dad.
** Leonardo and Raphael tend to butt heads in prior incarnations, with much of it being because of Leonardo's leadership and Raphael often taking issue with it. In ''Rise'', due to Leonardo's new comedic personality and Raphael's friendlier personality, the two get along much better and have a less frosty dynamic. They do butt heads in the Movie, but unlike in prior incarnations, Raphael's anger is due to being [[AngerBornOfWorry afraid]] Leonardo's overconfidence will make a mistake that will cost him his (and potentially the rest of the family's) life, something Leo comes to realize near the end of the film.
* AdaptationSpeciesChange: [[DownplayedTrope Downplayed]]. The protagonists are still mutated turtles, but they're all different types of turtles in this continuity; while Leonardo remains a red-eared slider like they are in most iterations, Donatello is a soft-shelled turtle, Michelangelo is a box turtle ([[MythologyGag which the brothers were]] [[Film/TeenageMutantNinjaTurtles2014 in the]] Creator/MichaelBay [[Film/TeenageMutantNinjaTurtlesOutOfTheShadows films]]), and Raphael, a snapping turtle.
* AtrociousAlias: The brothers and their friends call themselves "Mad Dogs", but it clashes so much with their appearance that nobody but themselves refer to them by that title. Leo himself points out that they should name themselves something more reflective of them being turtles. In the Movie, they don't refer to themselves as this anymore.
* BadassFamily: While they aren't as well-trained as in previous versions, they can still hold their own in battle. As each episode goes on, they grow more and more proficient with their weapons. Splinter, while lazy, is a lot more badass that he lets on.
* BestFriend: They are all this to each other. While they're brothers, they are also good friends with each other.
* BioweaponBeast: [[spoiler: What the turtles were created to be. Draxum meant to create powerful mutant warriors using Splinter's DNA, but Splinter was able to escape with the recently mutated baby turtles.]]
* BrilliantButLazy: This applies to pretty much all of them in regards to their ninja training at the start. They can pull off some incredibly acrobatic feats when the moment calls for it, but often they'd rather goof off and just pursue their own interests, and their inability to take most situations seriously leads to things often spiraling out of control. This begins to change after Splinter finally becomes serious about training them.
* ColorCodedCharacters: As with every version, the turtles wear specifically-colored bandana masks allowing the audience to tell them apart:
** Leo: Blue
** Raph: Red
** Donnie: Purple
** Mikey: Orange
* CreateYourOwnVillain: Due to the Turtles accidentally releasing mutant mosquitoes from Baron Draxum's lair into the city, most if not all of the villains they face are [[NiceJobBreakingItHero technically their fault]]. To be fair, they probably would have been unleashed sooner or later.
* DiscardAndDraw: In their penultimate confrontation with Shredder all their mystic ([[MyFriendsAndZoidberg and tech]]) weapons [[WreckedWeapon get destroyed]] by him. Todd replaces them with gardening tools, reasoning that they're historically what ninjas were said to have used, but using their newly discovered Hamato Ninpo they manage to transform them into the weapons they're known for in all other adaptations.
* DivergentCharacterEvolution: Aside from being different species of turtles and carrying over the body types from the 2012 cartoon, the turtles' outfits are more distinct; Leonardo wears matching fingerless gloves and spatting, Raphael also wears spatting in the form of bandages as well as a belt, and his bandanna covers his head in full, Michelangelo has marked several areas of his body to emphasize his role as an artist, and Donatello wears a full bandanna with goggles over it, and a variety of technological gear, with his shell being covered by a complex, multi-use backpack.
* DudeWheresMyRespect: While they're not as impressive as most versions, this team of turtles has scored some fairly impressive wins. Nevertheless, most characters casually disregard their fighting abilities.
* {{Fanboy}}: All of them are huge fans of Sydney Allen, "Jupiter Jim" movies and action star Lou Jitsu.
* FourTemperamentEnsemble
** Sanguine: Mikey is the outgoing, cheerful, but somewhat naive and childish brother as TheBabyOfTheBunch.
** Choleric: Raph is passionate and naturally wants to lead, but also headstrong and doesn't think things through.
** Melancholic: Donnie is analytical and organized, but also incredibly snobbish and self-centered.
** Phlegmatic/Supine: Leo is dependable, easy-going, and flexible, but also somewhat lazy.
* FoolishSiblingResponsibleSibling: Unlike previous iterations where this trope was rather cut and dry, it's zigzagged here. Depending on the situation, every turtle has the occasion where he acts very irresponsible and foolish. Typically, Raph tries to act more responsible as the oldest, but his lack of foresight and impulsiveness tends to give him some bad ideas and plummets him into the Foolish role. When Raph is acting foolish, the responsible role tends to either go to Leo or Donnie, depending on the scenario.
* GenreMashup: When they try out to be a band in an episode they want to mashup their individual music tastes into a Glam Rock-Soul-Techno-Rap sound. They think it sounds great but in reality it's done so badly an army of Albearto animatronics all self-destruct.
* HappilyAdopted: People had their doubts in the first impressions in regards to Splinter, but with additional screentime it's clear that the turtles love him and he loves them in return. As later revealed that they are all technically related, at least by DNA, it doesn't seem to really matter to them anyway, they're still family no matter what.
* HeCleansUpNicely: All of the Turtles look pretty spiffy in the formal black suits they wear in "The Clothes Don't Make the Turtle." In that same episode, many fans took note of how good they look in more flattering street wear as well.
* HypocriticalHeartwarming: The brothers often poke fun and tease each other, even resorting to petty physical harm, but that sort of thing is ''their'' thing. They don't appreciate when other people make fun of their brothers.
* IKnowMortalKombat: Their primary form of training comes from emulating Lou Jitsu movies.
* ImprobableWeaponUser: Thanks to Splinter's "training" of [[WaxOnWaxOff watching Lou Jitsu movies]], they're ''very'' skilled at using ladders and [[ShamuFu fish]] in combat, [[TheManMakesTheWeapon not unlike a Jackie Chan movie]]. In the series finale after their weapons are destroyed Todd replaces them with gardening tools, citing the historical use of this trope by ninja.
* InSeriesNickname: As per usual, Leo, Raph, Donnie, and Mikey, but they do have other much more affectionate nicknames for each other. Leo has been referred to as "Leon", Donnie has been called "Donald", and Mikey has been called both "Michel", "Miguel", and "Angelo".
* InTheHood: Their default disguise when they have to go out during the day.
* KidHero: One of the youngest versions of the turtles there has ever been.
* TheKnightsWhoSaySquee: "The Evil League of Mutants" gets the turtles giddy as hell when they realize that [[spoiler:their father is Lou Jitsu, whom they are big fans of.]]
* LeParkour: Comes with being a {{Ninja}}, across the roofs of New York.
* NamedAfterSomebodyFamous: [[ThemeNaming As usual]], they're all named after iconic Renaissance artists.
* PhoneaholicTeenager: The turtles here use their phones a lot more than previous iterations, mostly for entertainment purposes. Their over-reliance on their phones is addressed in ''Todd Scouts'', in which Splinter confiscates them.
* PowerIncontinence: Bordering on DramaPreservingHandicap, their stolen magic weapons occasionally malfunction. Not to be left behind, Donatello's tech also hiccups sometimes.
* RelatedInTheAdaptation: [[spoiler:Splinter was purely an adoptive parent in most other continuities. Here, his DNA was actually used in the Turtles' mutation, making him somewhat biologically their father]].
* SiblingTeam: TheTeam consists of all four brothers. Occasionally accompanied by April or sometimes Splinter.
* TookALevelInBadass: They begin as fairly unskilled due to Splinter slacking on training them in ninjitsu and struggle to use their mystic weapons properly. Over the course of the series, they slowly master their weapons' mystic properties. After Splinter gets serious about training them, they also gain a lot more combat proficiency and some stealth abilities. [[spoiler:They take another massive one in the series finale when they gain access to Hamato Ninpo, granting them the ability to manifest their mainline signature weapons from pure energy while also giving them mystic abilities related to their previous mystic weapons]].
* TrademarkFavoriteFood: As per the norm, the turtles love pizza and stacks of empty boxes can be seen around the lair if they aren't shown eating it.
* UnskilledButStrong: Compared to other incarnations, the Turtles here have far less formal training, but make up for it in the use of ninja mysticism that allows them to perform superhuman feats such as teleportation, energy projection, and high-level super strength.
* WellDoneSonGuy: So much so that Splinter's hugs are considered premium rewards by his sons.
* WouldHitAGirl: They have few reservations on retaliating against female antagonists. Foot Recruit, in particular, has fought and been struck by each brother at least once.
* WreckedWeapon: In the pilot, they all had their signature weapons from previous series. But, save for Donatello, they end up being destroyed during the battle against the Baron Draxim's minions. They gain their current ones after raiding the Baron's weapon storage. Though [[HowDoIShootWeb still need a handle on how to use them properly]]. [[spoiler:Unfortunately, the reawakened Shredder proceeds to destroy them in "Shreddy or Not". Luckily, through the use of Hamato Ninpo, they regain their signature ones with a few mystical perks in "Rise".]]

-->'''Voiced by:''' Creator/EricBauza (English), Jorge Roig (Latin American Spanish)

----
* {{Acrofatic}}: Despite his stature, he can still fight pretty swiftly. Best exemplified in the Season 1 finale.
* AdaptationalJerkass: Subverted. At first, Splinter may come off as more of a rude jerk than he has ever been. However, as the first season goes on, his "jerkness" becomes more like a bad first impression and he shows (and says) that he truly does love his sons on multiple occasions. He also has the least portrayed ParentalFavoritism, and is regarded as a father first and a teacher second.
* AdaptationalNiceGuy: While certaintly more of a irritable reckless goofball screwup than past incarnations, he is also the version of Splinter that shows no ParentalFavoritism and treats all of his sons equally. He also allows his sons to act like normal kids and prioritizes their wellbeing's over being a ninja, even [[spoiler: shredding his ancestors' ancient scroll when they suggest [[ScrewDestiny leaving his sons to die.]]]] He occasionally does stuff like watching movies with them, calls them by their signature colors as their [[AffectionateNickname Affectionate Nicknames,]] and offering a hug as incentive for a mission, which all four gladly accept before he can offer something better. Most of his teachings towards them was due to wanting to show off, but he never [[spoiler: wanted to force the Hamato destiny of protecting the Dark Armor onto any of them, so when he realizes the Foot's plan, he opts to fight them himself, and tells April to tell them that he loves them.]] It's no wonder that these turtles call Splinter "dad" more casually than any other version.
* AdaptationalUgliness: This Splinter is shorter and chubbier and has a more wrinkled face compared to past incarnations.
* AdaptationNameChange: Although Splinter's real name is still Hamato Yoshi, he more often went by the StageName [[spoiler:Lou Jitsu]].
* AdaptationPersonalityChange: Unlike every other incarnation where he is wise and active, Splinter in this one is much goofier and lazier. He later becomes more active near the end of Season 1.
* AdaptationSpeciesChange: The original Splinter is a pure mutant rat. This is another version where Splinter is a human turned rat hybrid.
* AmbiguouslyBi: He was canonically in a relationship with Big Mama prior to the events of the series. However, he and Draxum have a lot of subtext with each other, ''especially'' in season 2.
* BerserkButton: When Leo dismissed him as "just a rat" in ''Evil League of Mutants'', he blows up. [[spoiler:Justified because he's really Lou Jitsu and being called a rat just reminds him of the situation he's stuck in.]]
* BrainBleach: Inflicts this on his sons thanks to his robe getting frayed, exposing his tighty-whities.
* BrilliantButLazy: He's most comfortable in front of the TV, but when pushed he reveals himself to be a fierce combatant. [[spoiler:This is because, back when he was Lou Jitsu, all he cared about was fame and fortune instead of tradition.]]
* CerebusRetcon: Splinter watching Lou Jitsu films? Funny. [[spoiler:Splinter watching them because he wants to relive his GloryDays ''as'' Lou Jitsu? Not so much.]]
* CharacterDevelopment:
** After finding out about [[RealAfterAll Shredder's existence]] in ''Shadow of Evil'', he becomes a lot more serious in training the turtles. He also becomes a much more attentive parent in general.
** [[spoiler:He initially can't stand to be around Baron Draxum, understandably due to his part in turning him into a mutant rat (even if not intentionally), which isn't helped by Draxum's LackOfEmpathy. After "Hidden City's Most Wanted", however, which has Draxum point out that he wouldn't have his sons if not for him, [[JerkassHasAPoint Splinter realizes he's right]], and at the prodding of Michelangelo, the two start trying to get along. By "Anatawa Hitorijanai", Splinter quickly apologizes to Draxum for doubting him when it looked like [[FakeDefector Draxum was working with the Shredder]], suggesting that he's come to accept him as part of the family.]]
* CompositeCharacter:
** [[spoiler:Combined with SparedByTheAdaptation, but much like [[WesternAnimation/TeenageMutantNinjaTurtles1987 his 1987]] and [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 incarnations]], he's a still living Hamato Yoshi who mutates into Splinter, not a dead man whose pet becomes mutated and the Turtles' mentor.]]
** Splinter's dumpier physique, crude, goofier personality, and generally less hands-on training methods give him some resemblance to the Ancient One, a major character in Seasons 4 and 5 of the 2003 series who was briefly Leonardo's teacher.
* CrouchingMoronHiddenBadass: Not too "hidden" if you are familiar with earlier incarnations of Splinter, but since this version of him spends the majority of Season 1 as a lazy, goofy couch potato, watching him absolutely wreck all four Turtles and be a fairly proactive ninja in ''Shadows of Evil'' has this effect. Even with a bad back he manages to school his sons in battle, and despite the occasional slip-up due to being out of shape, he still performs some rather amazing feats throughout the episode.
* DatingCatwoman: [[spoiler:As Lou, he had a romance with Big Mama.]]
* {{Deuteragonist}}: A large part of the series centers around his relationship to his sons, and he, [[spoiler:through his history with Big Mama, Draxum's machinations, and his clan's ancient feud with the Shredder]], acts as a central connective thread between the series' main villains.
* DopeSlap: Chops his sons in the forehead when they screw up.
* FanDisservice: Splinter gets shaved and shirtless a distressing number of times in the series.
* FightingSpirit: While his sons can do rather impressive feats when they unlock theirs, Splinter's is revealed to be absolutely enormous, powerful, and shaped like [[spoiler:his Lou Jitsu persona to boot.]]
* FlashStep: He's the first character in the show to do this consistently.
* {{Foil}}: ''Jupiter Jim Ahoy!'' makes him one to Marcus Moncrief, the star of the "Jupiter Jim " movies. [[spoiler:Whereas Splinter/Lou Jitsu has essentially become forgotten barring the Foot Clan being fans of him, Marcus is shown at a Sci-fi convention willing to sign autographs. They both surround themselves with paraphehalia related to their lives as movie stars too. The main differences is that Marcus is now LostInCharacter and assumes he really ''is'' Jupiter Jim and has paralyzed various cosplayers dressed up as enemies in his films while Splinter can easily remember his "normal" life when not in front of a camera, happily talking about his time as Lou and all of the actors he worked with. Plus, Marcus doesn't have anything ''outside'' his life as Jupiter Jim, but Splinter has his sons.]]
* FormerlyFit: Got rather pudgy and squat after only a few years of raising his kids.
* FreudianExcuse:
** A lot of his rather hands-off parenting and irresponsible actions could be traced to [[spoiler:him yearning for his GloryDays as Lou Jitsu. This is most prominently presented in ''The League of Evil Mutants'' and ''Turtledega Nights: The Ballad of Rat Man''. "Goyles, Goyles, Goyles" retroactively implies that he's been suffering from PTSD too.]]
** ''"E-Turtle Sunshine of the Spotless Mind"'' reveals that [[spoiler:the reason he rejected the Hamato Clan's responsibility of defeating the Shredder, is that his mother abandoned him and left him with his grandfather to fufill that destiny. That painful memory still haunts him to this day.]]
* GenerationXerox: [[spoiler:He looks very similar to his grandfather, Sho, just with rat characteristics.]]
* GiverOfLameNames: He often refers to the turtles by the color of their headbands rather than by their classical artist names in the early episodes. [[spoiler: Season 2 reveals that he had this even as Lou Jitsu, referring to the pre-mutated Leonardo and Raphael as "Green" and "Green #2".]]
* GoodParents: While he can screw up more often that past incarnations, Splinter in this series may have the best portrayals of him as a father. He shows no ParentalFavoritism, wants his kids to still be kids and have a happy life, is more affectionate towards them, steps in the way of a fight just to protect them, and shows how he is proud of every single one of them. It's no wonder that the turtles call him "Dad" more times in this series than in past incarnations.
* GrumpyOldMan: This incarnation spends most of his time watching Lou Jitsu movies, becoming annoyed when he's interrupted. [[spoiler:This ties into his FreudianExcuse as seen above.]]
* HiddenDepths:
** The fact that he knows of the Mutant Underworld. In the first episode, he has a marker with a similar emblem Baron Draxum used to enter it.
** ''Al Be Back'' reveals that he has an amazing operatic voice.
** ''The Evil League of Mutants'' reveals that [[spoiler:he was once the human Lou Jitsu, an action star and Battle Nexus Champion.]]
** ''The Ancient Art of Ninja Hide and Seek'' reveals that [[spoiler: he has history with Big Mama and ''Many Unhappy Returns'' reveals that they're exes and he once tried to propose marriage to her.]]
** In ''Jupiter Jim Ahoy!'', he reminisces on his time as [[spoiler:Lou Jitsu, but instead of dwelling on his lost glory, instead humbly talks about all the people who he had fun working with in the film shown in the episode, talking about the experience with fondness, and remembers all of their names.]]
* InstantExpert: Masters Leonardo's mystical odachi with swift ease.
* InternalDeconstruction: [[spoiler:Unlike most incarnations of Hamato Yoshi turned into Splinter, this one shows how heavily affected Splinter is transformed into a rat and how much it has affected him. Before the transformation: he was kicking-ass as the movie star Lou Jitsu. After the transformation: a shell of his former self, wishing to relive his glory days.]]
** The show also demonstrates [[spoiler: how the pressures of the Hamato clan weighed on him. Contrary to the dutiful Hamatos of others shows, he grew up ''resenting'' that he and his family were expected to sacrifice so much for a sake of destiny and duty. As a result, he rebelled against the Hamato Clan's teachings and refused to return or reconcile with his family.]]
* IWasQuiteALooker: [[spoiler: He was absolutely ''handsome'' as Lou Jitsu.]] That, and his mutation didn't make him short and fat, he just shrunk in stature and swelled in width over time.
* JerkWithAHeartOfGold: His "jerk" sides really come off as a bad first impression in the earlier episodes. Splinter's added screen-time has shown he genuinely loves all his sons.
** He's got a lovely framed family picture with them in ''Down with the Sickness''.
** In ''The Fast and the Furriest'', he seems genuinely sad that his boys don't like his T.G.I. Parmesan idea, showing he does care what they think.
** In ''Mascot Melee'', he adores their gift of a brand new robe so much that he will only use it on "the most special occasions," unfortunately, in the process ruining their hopes that he'd replace his worn-out robe. Later episodes reveal that he does wear it though.
** He outright helps Raphael defeat the titular antagonist of ''Mrs. Cuddles'' after initially making fun of him, and claims nobody messes with his family (or his TV time).
** ''The Evil League of Mutants'' realizes that he has been quite a jerk to the turtles and apologizes for it, to which the turtles forgive him and give him a hug at the end.
** In ''Turtledega Nights: The Ballad of Rat Man'' he tricks Donnie and Mikey into entering a mutant destruction derby with him to relive his glory days [[spoiler:as Lou Jitsu]]. Once Donnie figures this out and makes it clear that the lie hurt his feelings and Splinter realizes he's been a jerk, he sincerely apologizes and is completely willing to drop it and go home in that instant, even telling Donnie he doesn't have to compete when he decides to keep going after all.
* LateArrivalSpoiler: [[spoiler:The season 1 finale, season 2 premiere and season 2 episode "Goyles, Goyles, Goyles" states it outright that Splinter was originally Lou Jitsu.]]
* LovesMyAlterEgo: [[spoiler:While the turtles love him as their adoptive father, they're starstruck when they learn that the Battle Nexus champion Lou Jitsu (who he also is) provided them with their human DNA. Even after learning that Splinter is Lou, they still love him as he is.]]
* OOCIsSeriousBusiness: If Splinter is ''not'' his couch potato self, things are gonna get dire.
** In ''Evil League of Mutants'', he gets utterly pissed off at the turtles when they dismiss him as "just a rat" and grounds them. After realizing that they ran off, he is sitting alone in his couch without the television on, waiting for them to return.
** In ''Shadow of Evil'', the normally proudly lazy Splinter becomes ''very'' proactive when he finds out that the Foot Clan are still around [[spoiler:because they're planning on resurrecting [[AncientEvil The Shredder]] and the end of the episode has him decide to ''finally'' take training seriously]].
** In ''The Ancient Art of Ninja Hide and Seek'', he tasks his sons to retrieve something at the Grand Nexus Hotel and waits for them to return ''for three days straight'', still standing on top of the apartment roof.
** In The Movie, Splinter ''immediately'' stops making fun of Casey Jones and starts taking his warnings seriously when Casey reveals that the alien invaders who decimated the future he comes from are called "The Krang", which the Hamato Clan have history with.
* OffingTheOffspring: Two of the symptoms of the "Rat Flu" illness that Splinter can catch consist of viciously attacking anyone nearby. Even if they're his sons.
* OldMaster: Despite being middle-aged, well past his prime as [[spoiler: Lou Jitsu]], he's still capable of taking on all four of the turtles at once without breaking a sweat.
* PapaWolf: While not on the extreme end, the moment he realized that his sons might be in ''serious'' trouble, he went full ninja to try to rescue them. By the season 1 finale, he's completely this [[spoiler:giving up the chance of Shredder coming back to life if it means it will save his sons' lives.]]
** [[spoiler:"Goyles, Goyles, Goyles" reveals that back when he was still Lou he kicked Draxum's ass when he learned that the baby turtles that he grew attached to was going to become experimented on.]]
** [[spoiler:When he consults with the Hamato Scroll in what to do about his son's being held hostage for ransom, while he might have been tempted by the other options, the moment the spirits tell him to sacrifice his sons, he shreds the scroll. He will not entertain that thought from no one.]]
* ParentsAsPeople: Though must of it can be chalked up to RuleOfFunny, Splinter ''definitely'' isn't going to win any "parent of the year" awards. He can be extremely self-centered, he can be inattentive to the point of being neglectful, and sometimes he's more immature than his sons are. But he's also generous with praise and much more openly affectionate than any other incarnation of Splinter (except when it's funnier that he isn't), and while he can get too caught up in himself he truly wants the best for his sons and would go to Hell and back for them. [[spoiler:Once it's revealed that he's Lou Jitsu, we see a (rat)man who truly does love his sons yet is held back by wanting to relive his glory days of an action star/Battle Nexus champion and is going through PTSD over his transformation.]]
* PrehensileTail: His tail can be used to supplement his punches and kicks, letting him perform typically high-commitment/risk moves without leaving himself too open.
* RememberTheNewGuy: During one of his more intense training sessions where he tried to teach his sons how to spot hidden enemies (by hunting him), [[https://youtu.be/wpLOKsiJKo8?t=50 Splinter disguised himself as a ''fifth'' turtle whose presence no one thought to question.]]
* RuleOfSymbolism: [[spoiler:When he fights in ''Endgame'' and ''Many Unhappy Returns'', he's dressed as he was when he was Lou Jitsu. This shows that while he can no longer become Lou, he's accepted himself as he is.]]
* SaveTheVillain: [[spoiler:He attempts to pull Big Mama into an escape portal with him at the end of "Battle Nexus: New York" after the Foot Recruit gets control of The Shredder with the intention to wipe out all their enemies. However, before she can escape, The Shredder cuts off the web line attaching her to Splinter]].
* SecretKeeper:
** In ''The Evil League of Mutants'' he knows of how [[spoiler: Baron Draxum used the DNA of Lou Jitsu (aka himself) to make the turtles.]] Lampshaded by Leo who says that he has a shady past.
** In ''The Ancient Art of Ninja Hide and Seek'', [[spoiler: he apparently has some...''[[ImpliedLoveInterest suggestive history]]'' with Big Mama. Confirmed in ''Many Unhappy Returns'' when he tells Leo that he and Big Mama are exes (and he even proposed ''marriage'' to her).]]
* SignificantDoubleCasting: He has the same voice actor as Lou Jitsu [[spoiler:because he ''is'' Lou Jitsu.]]
* SparedByTheAdaptation: [[spoiler:Due to being a CompositeCharacter of Hamato Yoshi and Splinter, much like his 1987 and 2012 incarnations, he's a still living Hamato Yoshi who mutates into Splinter, not a dead man whose pet becomes mutated and the Turtles' mentor.]]
* StrongFamilyResemblance: Formerly tall and strapping, he eventually became [[MiniatureSeniorCitizens short and wide like his grandfather before him]].
* SurprisinglyRealisticOutcome:
** Splinter is unmatched in combat, but due to his advanced age and being out of practice, his back can easily throw out if he gets too intensive.
** Because he's always on his ass watching television, he doesn't find out until Season 1 is halfway over about his sons fighting Baron Draxum and the Foot Clan.
* TakeAThirdOption: [[spoiler:Consulting the scrolls in the Season 1 finale on how to stop Shredder leaves him with two choices: either he takes the last piece of the armor and runs away, having his sons die as martyrs but saving humanity, or he can give the armor piece up to save his sons and doom humanity. Splinter's decision? ''Shred the ancestor's scroll'' and say screw all of that because he's going to do save humanity ''and'' his sons.]]
* ToughLove: A very downplayed example as Splinter genuinely loves and cares for his sons. Splinter is okay with letting the boys wander and do their own thing, but is often (sometimes unnecessarily) strict with them when he feels like there's a lesson to be learned. Stated by voice actor Eric Bauza to practice this.
** Proven both in ''Flushed but Never Forgotten'' and ''The Ancient Art of Ninja Hide and Seek'' where he says that the boys don't seem to learn when fear is not involved, which is why he's so hard on them sometimes.
** Demonstrated again in ''Todd Scouts'', where he leaves the turtles in the middle of the woods and confiscates their weapons and phones in order to teach them self-reliance. Somewhat softened by the fact that he brings Todd along to give the turtles wilderness survival guidance.
* WalkingSpoiler: At first, you think his little quirk of watching Lou Jitsu films and the Lou Jitsu paraphernalia in the cave is that, a quirk. Halfway through season 1, [[spoiler:we learn that it's not ''just'' a quirk because he ''was'' Lou Jitsu and he's stuck trying to relive his glory days.]]
* WasOnceAMan: [[spoiler:He was once known as the famous action star Lou Jitsu.]]
* WaxOnWaxOff: His methods of training usually stems down to "Make my sons watch Lou Jitsu films and see what they make of it." [[spoiler:This is actually a way for him to relive his glory days ''as'' Lou Jitsu.]]

[[folder:Raphael]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/raph_0.png]]
[[caption-width-right:350:[[HotBlooded Ready For a Fight]]]]
-->'''Voiced by:''' Creator/OmarBensonMiller (English), Alan Prieto (Latin American Spanish)

The eldest of the brothers and the designated leader, Raph is headstrong and passionate about his role. Although he's not the most bookish or quick-witted, his compassion and determination are undeniable.
----
* AbsurdPhobia: Subverted. Raph was afraid of Mrs. Cuddles, a bunny puppet used for a kid's show. Though he was later proved to be right to be afraid of her.
* AdaptationalCurves: He's much bigger and bulkier compared to his previous incarnations, let alone the other turtles in this series.
* AdaptationalNiceGuy: In comparison with Raph's JerkWithAHeartOfGold incarnations, this one is considerably more "Heart of Gold" and has yet to display "Jerk." During the first episode, he's the one who spots Mayhem while he and the others are goofing off and his ''immediate'' response to seeing an animal looking lost and scared is to go help it.
* AdaptationalWeaponSwap: Unlike the previous incarnations, he wields Tonfa instead of Sai.
* AdaptationSpeciesChange: In this version, he's an alligator snapping turtle who has spikes on his shell and he is much bigger than his brothers.
* AffectionateNickname: Known mostly as Raph by his brothers or Red by Splinter.
* AgeLift: In most of his incarnations, Raphael is usually not the oldest of the turtles despite all of them technically being the same age (general fan theory is he is the second oldest which is is confirmed in the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 series]] and ''WesternAnimation/TeenageMutantNinjaTurtlesMutantMayhem'', although Co-creator Kevin Eastman [[https://www.reddit.com/r/IAmA/comments/2dkbtl/comment/cjqb686/ has stated that he believes Don is older than Raph, making him the second youngest]]). Here, he's the oldest one of his brothers, being a year older than Leo and Don and two years older than Mikey.
* BabyTalk: Has this talk specially reserved when talking to his younger brothers or cute animals.
* BattleCry: "HOT SOUP!"
** It serves as nice foreshadowing as seen in ''The League Of Evil Mutants'' [[spoiler:since this is the CharacterCatchphrase of Lou Jitsu (aka Master Splinter)]].
* BigBrotherInstinct: Raphael is a very protective big brother in this series, and his large size allows him to carry them with ease. He gets [[AnnoyingYoungerSibling bullied by his brothers sometimes]], but it's all lighthearted. The moment you so much as touch or even ''insult'' his brothers, you better get ready for a world of hurt. Especially if it's the littlest brother Mikey.
* TheBigGuy: Literally and figuratively, he's the tallest and bulkiest of the turtles and the main muscle of the group.
* BoisterousBruiser: He's pretty proud of how tough he is.
* BrainwashedAndCrazy: [[spoiler: A victim of this at the Kraang's tentacles in the movie.]] Luckily he eventually manages to break free.
* BrokenPedestal: Zigzagged. Was a huge fan of the wrestler Ghostbear, who outright admitted he cheated his way to fame. However, despite knowing Ghostbear's true personality and the fact that the former wrestler seeks every opportunity to get back at Raph and his brothers for his humiliating defeat, Raph still admires him.
* BruiserWithASoftCenter: His profile states "his muscles are bigger than this brain, but his heart is bigger than his muscles."
* TheChainsOfCommanding: Even though he's only the self-appointed leader, when they're truly in a bind his brothers look to him for a plan. Combined with his self-admittedly being a meathead this causes him a lot of trouble in the [[DarkestHour series finale]] as he can't think of any way to defeat [[spoiler: Shredder]].
* CharacterCatchphrase: "Like a boss!"
* CuteLittleFangs: Well, to a degree. One of this teeth is a snaggle-tooth.
* TheDeterminator: None of his brothers wants to follow his plans? Raph doesn't care, going so far as dragging all four of them along with the single arm he can employ in ''Stuck on you''.
* DoppelgangerSpin: [[spoiler:He gains the ability to generate energy-based clones of himself after unlocking his Hamato Ninpo]].
* DualWielding: As per usual, but with Tonfa instead of Sai.
* DumbMuscle: He's not very bright, and prefers to move into situations fists first without any consideration for strategy.
* FightingSpirit: Raph's mystic Tonfa allow him to manifest a massive energy projection around himself like a suit of armor.
* FriendToAllLivingThings: Raphael himself states that animals love him, a MythologyGag to former adaptations. Unfortunately, Mayhem doesn't count.
* GentleGiant: He's friendlier than most incarnations of the character, with very little of the traditional BigBrotherBully.
* GoMadFromTheIsolation: After about five minutes.
* GoodIsNotSoft: Downplayed a bit. While he starts off the show as being very protective and affectionate towards his brothers, and retains that affection throughout the show, Raph slowly starts to allow them to do things for themselves- and, in turn, has less objections towards being harsher or less coddly towards them. ''Pizza Puffs'' and ''Sidekick, Ahoy!'' display this.
* HardLight: His mystic Tonfa give him the ability to manifest solid energy constructs, specifically [[FightingSpirit extensions of his own body]].
* HatesBeingAlone: Oh lord yes. ''Man vs Sewer'' shows that he will break down and freak out, ''violently'', if he's left by himself for even a short amount of time. This trait is bad enough that Leo, normally not the most serious turtle, becomes TheDeterminator in finding him once he's isolated because of the damage he could cause. Even more unsettling in that there's little information on where this fear stems from.
* HeroicBSOD: Had one in ''Mrs. Cuddles''.
** And again in ''Man vs Sewer'', where being separated from his siblings and attacked by the Sando Brothers essentially pushes him into a breakdown.
* KnightTemplarBigBrother: PlayedForLaughs. Raph, as the oldest in the iteration, is far more outwardly protective of his brothers than before, particularly towards Mikey.
-->'''Raph (while attacking Foot Brute)''': I'LL DEFEND YOU, MIKEY!
* LargeAndInCharge: Raphael is much larger and muscular than the other turtles and the leader of the team.
* LawOfChromaticSuperiority: Invoked, as he's the leader this time simply because he stepped up.
* LeaderWannabe: In this series, Raphael is actually the self-appointed leader due to him being the oldest and his brothers being largely disinterested in the position. It's shown he's not very good at making decisions or strategizing, relying more on brute force.
** In one episode, he's reduced to reading inspiring quotes he wrote on his hand in order to keep the team motivated.
** It is shown, however, that he is actually pretty decent when it comes to broader objectives, like assessing team dynamics and determining goals for the group. He's also shown to be quite a bit more emotionally competent and mature as the show goes on.
* TheLancer: Played with. He still views himself as the leader, but Leo is mostly the one who organizes things during battles without usurping his position. Though obviously from the outset, Raph is not THE leader he thinks he is, putting him in this position.
** Following Season 2 finale, this is played straight with Leo eventually given the leader role by Splinter.
* MythologyGag: He's an alligator snapping turtle in this series, likely an allusion to having owned a snapping turtle, Spike, as a pet in the 2012 series. His design also looks similar to Spike's mutant form, Slash, with his spiky shell and sharper looking mouth.
* NoodleIncident:
** When Raph gets stuck in Warren Stone's glue trap, Leo says, "Not again..."
** Another one in ''Newsworthy'': "You ruined that woman's 95th birthday."
* OnlySaneMan: He has his moments, notably in ''Jupiter Jim Ahoy!'', where he's the only one who notices there's something wrong with Marcus Moncrief, or in ''Pizza Puffs'', where he's the only turtles who realizes it's a bad idea to eat Meat Sweat's poisoned food.
* ThePowerOfLove: A downplayed variant. When first learning how to use his mystic powers, Raph starts off with PowerIncontinence, but the first major instances where he uses his BattleAura is typically motivated by wanting to protect his brothers. Eventually, however, he uses it more regularly and can use it any time he wants.
* PrimalFear: ''Don't leave him alone.'' There's also some emphasis on the word "primal" given that Savage Raph acts a bit more like an animal than usual.
* PromotionToParent: Due to Splinter lazing around and doing his own thing, Raph has taken it upon himself to mother his brothers, to the point of being overprotective.
* RunningGag: His "fear stink", which also had variants in "amazing stink" and "victory stink". Another FurryReminder, here being that snapping turtles release odors when stressed.
* ThirdPersonPerson: At least once per episode. He doesn't talk like this all the time, unlike many examples, however.
-->'''Raph:''' Only Raph can use the third person!
** When he goes savage in ''Man vs. Sewer'', his speech noticeably deteriorates into ''only'' being third person.
--->'''Raph:''' No brothers! Savage Raph '''''ALONE'''''!
* TookALevelInBadass: From vaulting himself against a wall trying to use his Tonfa in the first episode to ''impressing Splinter with punching Draxum'', he leveled up quite a bit over the course of the first season.
* UnskilledButStrong: He clearly lacks proper leadership or basic strategic capabilities, but makes up for it by being the strongest Turtle, and tends to fall back on using the powers of his Tonfa to overpower his opponents.
[[/folder]]

[[folder:Leonardo]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/leo_11.png]]
[[caption-width-right:350:Makin' A Scene]]
-->'''Voiced by:''' Creator/BenSchwartz (English), Miguel Ángel Leal (Latin American Spanish)

The fast-talking quipster of the brothers, Leo always wants to have the last word. While he shows great potential as a leader, he'd much rather joke around and relax.
----
* TheAce: [[DownplayedTrope Downplayed]]. He is a natural strategist and leader, especially when contrasted with Raphael. He's also the fastest of the brothers without sacrificing any of his strength. ''Lair Games'' also shows that he's won the games for five years in a row with seemingly little competition.
** Subverted in getting used to mystic powers, where he CantCatchUp.
* AcquiredSituationalNarcissism: He gets a particularly bad case of this in the beginning of the movie thanks to the defeat of the Shredder, which ends up getting bolstered further when Casey Jones reveals that in the future he'll become the greatest ninja of all time, leading him to believe that he is incapable of doing wrong. [[WhatTheHellHero Casey chewing Leo out]] for not living up to the man he was supposed to be humbles him.
* AdaptationalComicRelief: ''Rise'' [[AgeLift removes Leo's status as the oldest]], changing his dynamic with his brothers. He's thus much less serious and more rebellious compared to previous incarnations, with no interest in being the leader despite having the talent for it. He's gotten a brand of humor able to exasperate ''Mikey''.
* AdaptationalPersonalityChange: The most drastic one out of all the turtles. Leonardo is often TheLeader, the OnlySaneMan, and the one most concerned with the responsibilities he has. Here, he's lazy, more of a jokester than ''Mikey'' and likes to push people's buttons for no reason than for his personal entertainment.
* AdaptationSpeciesChange: Subverted; the original Mirage version of the turtles are red-eared sliders, leaving Leo the only one to retain his original species.
* AffectionateNickname: Known mostly as Leo, but is also called Leon by his brothers (and himself) and Blue by Splinter.
* AgeLift: More of a slight lower. He's usually the eldest of the four brothers, despite being technically the same age as them; here, he's the second oldest along with Donatello - a year younger than Raph and a year older than Mikey. While official sources do not confirm it, fans are split on which twin is older.
* AmbiguouslyGay: This iteration of Leo has rather flamboyant body language, has yet to show any interest in girls beyond friendship, and in ''The Hidden City Job'' he visibly checks out a seemingly male Yokai's butt, and later openly fawns over Don Suave alongside Big Mama and her goons.
* AnimalGenderBender: Leo has the bright vibrant markings that red-eared sliders are known for. However, male red-eared sliders tend to have their markings dull and fade as they age; generally around five in turtle years and twelve in human years, so at fourteen, Leo's should be just as dull[[note]]and if not during Rise proper, definitely in the bad future where he's much older yet still has them[[/note]]. Him being a mutant provides a possible justification, but the turtles in most media are red-eared sliders with no visible markings whatsoever (though that could be a case of InformedSpecies).
* AnnoyingYoungerSibling: He frequently pranks and trolls Raph and Donnie who [[InvertedTrope may]] or [[PlayedStraight may not]] be older than Leo.
* BatmanGambit: His plan in ''Many Unhappy Returns''; [[spoiler:he goes to strike up a deal with Big Mama by having Splinter fight in the Battle Nexus in exchange for some help, while his brothers and April fight the Shredder, a plan which Splinter warns him is a ''terrible'' idea due to Big Mama being untrustworthy, which isn't helped by Leonardo constantly escalating the bargain. Once Big Mama ''does'' inevitably betray Leonardo, Leonardo reveals that he already planned for it, smuggles in their weapons, and due to the show they put on, Big Mama is forced to honor her side of the deal.]]
* BigBrotherInstinct: Despite no longer being the oldest, he is this to his youngest brother, Mikey, whom he shares a special bond with.
* BigBrotherMentor: The creators have described Leo having taken Mikey "under his wing." This is mainly seen with the two of them often hanging around each other whenever the turtles are off doing their own things.
* BlueIsHeroic: As is standard for the character.
* BrilliantButLazy: ''Could'' be the leader like most of his incarnations if he wanted, and shows some skill there on the occasion that he steps up, but isn't interested in putting in the effort. ''Lair Games'' shows that he's won the titular games for five years in a row, with the end of the episode heavily implying [[spoiler:he let Donatello win, just so that he wouldn't have to hear Splinter's snoring]]. He's shown in the second season to be very good with talking his way out of situations, manipulating villains, thinking quickly, and coming up with strategies, yet still shows little interest in being a leader in the same manner as Raph. His tendency to wing it on his own [[DeconstructedTrope ends up biting him massively in the movie]], as it leads to a cascading series of mistakes that give the Krang exactly what they need to invade Earth. It's only when he finally takes his role as leader seriously and starts coordinating with his brothers that they actually succeed in stopping the invasion.
* BrokenPedestal: Casey Jones considered his Leonardo to be the greatest ninja of all time and ended up becoming incredibly disappointed in seeing just how arrogant and impulsive he was as a teenager. Leonardo admitting to his weaknesses and learning to work alongside his brothers leads to the [[RebuiltPedestal pedestal being rebuilt]].
* CasualDangerDialogue: Leo is prone to making jokes and puns during a battle. According to him, this is how he copes.
* CharacterCatchphrase:
** Played with. He's clearly trying to ''come up'' with one, but ends up only yelling out whatever he's doing that moment, resulting in one incident of him shouting, "Kick and punch!"
** A frequent line he spouts when being chased is "I hate this! I hate this!"
* CharacterTics: Leo often dabs during certain moments, especially when striking a pose.
* TheChessmaster: Leo shows shades of this at the start of Season 2. He was able to completely orchestrate a plan with Big Mama and have everything fall into place, just as he had planned.
* TheComplainerIsAlwaysWrong: When the Turtles formally decide to become vigilantes in ''Origami Tsunami'', Leonardo disinclines them from hunting infamous criminals right out of the gate, reasonably suggesting that they go after more petty malcontents and gradually work their way up. The paper thieves he prods his brothers into pursuing turn out to be members of the ''Foot Clan''.
* CompositeCharacter: Interestingly, this version of Leo takes cues from most versions of Mikey, being a BrilliantButLazy jokester.
* TheConscience: Out of all the brothers, Leo is the most vocal and willing to call Donnie out when he's about to do something morally questionable.
* DeadpanSnarker: Perhaps the snarkiest incarnation of Leonardo to date. He is always ready with a quip or remark about their current situation.
* TheDeterminator: He may be scared and he might be outclassed, but he is ''not'' giving up.
* DifficultButAwesome: His portal ability granted by his odachi. Leonardo is very poor at using it early on in the series, often either failing to open a portal at all or opening it to the wrong location. However, as the show goes on, he noticeably improves with it, allowing him to counter and often disorient enemies with ease, along with making it an excellent fallback option when the characters are forced to retreat.
* FacialMarkings: He has two red stripes going down his eyes. Flashbacks reveal he had them even pre-mutation. Justified since he's a red-eared slider, which have the markings in real life.
* FatalFlaw: This Leo's biggest flaw is his pride, given that most of his problems stem from him trying to prove his own greatness, thinking he can find an easy way out of things or can trick his brothers into going along with his nonsense.
* TheGadfly: He has a tendency to act self-important and push people's buttons just because he ''can''. One of his defining quirks is how often he sticks out his tongue at everyone and everything.
* TheHeart: For as lazy and irresponsible as he is, he's the most concerned about doing right by others and considering how their actions might affect them. Even when he's the one causing problems, it's always a result of genuinely good intentions marred by his need to prove himself.
* HeroesPreferSwords: He's still baring his dual katanas, at least until he trades them in for an Ōdachi.
* HiddenDepths:
** While he acts fairly egotistical and sure of himself, as revealed in ''Portal Jacked'', Leo admits that he feels that he is ''nothing'' without his brothers.
** On a lighter note, ''The Clothes Don't Make The Turtle'' reveals that he's a huge fan of stage magic.
* HowDoIShootWeb: He has a much harder time grasping the mystic powers of his weapon when compared to Raph and Mikey brothers. Several scenes have him struggling to open a portal when he really needs it. He finally matures and grows into a competent fighter by the end of Season 1.
* ImpossiblyCoolWeapon: Unlike the previous incarnations, he wields an Ōdachi instead of his usual twin katanas, though he did use his original weapons briefly in the first episode.
* InferioritySuperiorityComplex: Due to how he CantCatchUp with Raphael and Michelangelo, Leonardo went to the extent of seeing himself as TheLoad in ''Minotaur Maze''. It puts his [[SadClown joking to cope]] in a new light.
* TheKlutz: Downplayed and justified, a FurryReminder of his being a slider; he's not the most graceful on his feet.
* TheLeader: In season 2 finale, he's officially given this role by Splinter like his other incarnations... [[spoiler:At the last closing seconds of the episode.]]
* LightningBruiser: Shown to be the fastest of the brothers -- outrunning both Raph and Mikey in the first episode even though they had a head-start ''and'' he needed time to get to his feet and grab his weapon -- and can almost effortlessly toss enemies around.
* MadeOfIron: A pretty notable example in the movie, where he endures an extended beatdown at the hands of Krang 1 [[spoiler:after he strands the both of them in a separate dimension and destroys the Technodrome]]. For perspective, Krang 1 in his PowerArmor can punch the ground hard enough to make it ''explode'', and he was so enraged at that point that he wasn't bothering to hold back.
* OneHandedZweihander: He occasionally wielded the Ōdachi with one hand. That said, Ōdachi literally translates to Greatsword.
* OnlySaneMan: [[DownplayedTrope Downplayed]]. While many episodes show him being the only one actually trying to be serious and think about other people (such as ''Bug Busters'' where he rightfully doubts Big Mama, or ''Man Vs Sewer'' where he constantly reins Mikey and Donnie in to find Raph), other episodes show that he can just as easily goof off and act in his own self-interest if he feels like it.
* OOCIsSeriousBusiness:
** In ''Insane in the Mama Train'', having adopted the new "Ninja of the Hamato Clan" persona, Leo does not make any puns, jokes, or one-liners more, enough for April to comment on it. This tic returns when he and his brothers return to their "Mad Dogs" selves.
** [[spoiler:As the lair is being decimated by The Shredder in ''Shreddy or Not'', Leonardo is so afraid that he makes no comedic quips, and spends his very brief fight with the Shredder trying to get away from him.]]
* PrettyBoy: Self-described for "putting the prettiest face first", then the trope name is echoed mockingly by Raph when it doesn't work. (He is of course, a mutant turtle, but he is the most conventionally pretty of the brothers by human standards.)
* SmarterThanYouLook: His laziness and constant one-liner spewing make him look rather dim, but he's shown on multiple occasions to be surprisingly good at long-term planning when he's motivated. He was also the only turtle to immediately mistrust Big Mama upon meeting her.
* TeleportSpam: [[spoiler:After unlocking his Hamato Ninpo, he gains the ability to teleport to wherever he tosses his dual katanas. He can also teleport other people to a katana's location, as shown when he tags Raph in during the final fight with Shredder]].
* ThinkingUpPortals: His Ōdachi can open portals from one place to the next, though he has a little bit of trouble reliably controlling it at first. He's gotten way better by the end of Season 1.
* TookALevelInBadass: Started out in the series being the most troubled out of all the brothers with learning his new Mystic Powers and frequently felt like that he simply can't stand next to his brothers skill-wise. However, with each coming episode, Leo just gets better and better. By the finale, not only is Leo able to hold his own against competent villains like the Guardsmen, he's now more or less mastered his portal power. ''Many Unhappy Returns'' shows this mastery off in full, with Leo using his portals to effortlessly play Big Mama and take down the opponents she pitted him and Splinter against.
* TheTrickster: Labelled as such in the toyline. As ''Many Unhappy Returns'' shows, this isn't an InformedAttribute. Despite appearing to not be taking the negotiation with Big Mama seriously and giving Splinter progressively worsening odds, he reveals that the whole escalation had been part of his plan the entire time to force Big Mama to uphold her end of the deal.
* VitriolicBestBuds: Type 2 with Donnie. They snark, banter, and tease each other a great deal, but at the end of the day do love each other very much and are shown/implied to hang out together by themselves many times.
* YouAreInCommandNow: In the movie, Leo's character arc is struggling with the fact that he's been made leader, with the others encouraging him to push forward despite their massive disadvantage due to the Krang.

[[folder:Donatello]]
[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/don_1.png]]
[[caption-width-right:270:[[TheSmartGuy Rocks Machines]]]]
-->'''Voiced by:''' Creator/JoshBrener (English), Pascual Meza (Latin American Spanish)

The smartest of the turtles, Donnie never hesitates to show off his inventions and rub his brain in others' faces. While his ego and desire to prove himself can make him a pain, he cares deeply about his family and only wants to prove himself to them.
----
* AbsurdPhobia: Donnie seems to be afraid of beach balls for some reason. It isn't really explained, but he mentions it frequently as his irrational fear.
** Possibly explained in "Lair Games". When clips of previous games are shown, one depicts a beach ball hectically ricocheting around a room with Donnie as a small child curled in fetal position, desperately trying to avoid it.
* AdaptationalBadass: His bo staff is much more highly mechanized than in other incarnations, giving him versatile ways of attacking. He's also the ''only'' Turtle to land a hit on Baron Draxum in the pilot, while the others were struggling with their new weapons. He's also got a highly mechanized backpack, with various different versions depending on the situation, making him easily the most prepared.
* AdaptationalJerkass: Donnie is generally [[NiceGuy the nicest]] of the Turtles in previous incarnations, sometimes being InnocentlyInsensitive at worst. This series portrays Donnie as more easily irritated by brothers' silly behavior, as well as having an [[InsufferableGenius incredibly large ego]]. He still gets along with April and his brothers [[JerkWithAHeartOfGold just fine]], though.
* AdaptationalWimp: Downplayed. The movie makes it clear that Donnie struggles doing the usual acrobatics without the use of his technology to help him, while in all other adaptations, he's as fit as his brothers.
* AdaptationInspiration: Donatello's artificial shell is a nod to the comics where his shell had to be replaced with a metal one after an attack from Bebop and Rocksteady. In this version, he starts out with the artificial shell over his real one and is made to be a soft-shelled turtle to justify him having one in the first place.
* AdaptationSpeciesChange: In this version, Donatello is a soft-shelled turtle.
* AffectionateNickname: Known mostly as Donnie, but is also called Don by his brothers (which, ironically enough, [[AdaptationalNameChange was his primary nickname]], in the [[ComicBook/TeenageMutantNinjaTurtlesMirage original Mirage comics]], the NES and SNES games and [[WesternAnimation/TeenageMutantNinjaTurtles2003 in the 2003 series]]) and Purple by Splinter, sometimes even Donald.
* AgeLift: In all incarnations (with the exception of the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 series]] and ''WesternAnimation/TeenageMutantNinjaTurtlesMutantMayhem'' in which Donnie is confirmed to be the second youngest), according to [[https://www.reddit.com/r/IAmA/comments/2dkbtl/comment/cjqb686/ Franchise co-creator Kevin Eastman, Donatello is the second oldest]] despite all four brothers being the same age. Here he and Leo are both a year younger than Raph and a year older than Mikey, making Leo and Don the second oldest. Although official sources do not confirm it, fans are divided on which "twin" is the older of the two.
* AlphaStrike: Against [[spoiler:Shredder]], Donnie brings out all of his tech at once to attack. And he means ''all'' of it.
-->'''Donatello:''' Eat ''science!''
* AwesomeBackpack: To compensate for his soft shell, Donnie's equipped himself with a mechanical cover for it that can unfold into a VTOL-styled JetPack. It also has [[ArtificialLimbs many retractable]] [[SpiderLimbs waldo arms]] tipped with various tools for quick building.
* BadassBookworm: Despite being the brains of the group, it doesn't mean he can't also bring the brawn. He was the only one able to score a hit on Draxum with the help of his more than stellar works of technology.
* BadassNormal: Up until the finale, Donnie has been able to handle mystical villains with non-mystical tech, with little room for compromise (he ''does'' use small magic at times to boost his gadgets). At the start of the series, he chose to stick with his Bo staff over the mystical weapons his brothers use.
* BerserkButton: He actually gets incredibly upset in ''The Ballad of Rat Man'' when he finds out Splinter lied to him about taking the Tank to a car show, more for the fact that Splinter ''lied'' than the fact that he brought the Tank to a demolition derby.
* BigBrotherInstinct: Although he is normally not very affectionate towards his family, he clearly has a soft spot for his younger brother Michelangelo. There is never a moment in the movie during a battle or danger where Donnie is not protecting Mikey and he is always focusing on his little brother's safety over his own.
* BigOlEyebrows: Draws them on his bandana.
* BreakingTheFourthWall: Does this on occasion.
* BrokenAesop: His arc about reluctantly accepting the mystical is potentially rendered moot during the show's finale where it's heavily implied that all yokai, and perhaps all magic, stem from [[spoiler:repurposed alien technology.]]
* CharacterizationMarchesOn: His ControlFreak tendencies throughout Season 1, such as trying to curb tendencies about his brothers he finds annoying or (literally) turning them into copies of himself, are heavily downplayed as it goes on, showing greater tolerance for the people around him, with most episodes in the series emphasizing [[InferioritySuperiorityComplex his desire for validation]], a character trait introduced in ''Bug Busters''.
* CompanionCube: He's ''very'' fond of his bo staff due to all the modifications he's made to it, even turning down a mystical Kusari-Gama-esque weapon while remarking "I'll never let you go" and caressing it.
* ComplexityAddiction: He seems to enjoy making things difficult. In "Donnie Vs Witchtown" he decides to artificially age worms rather than find older ones, and one comic has him believing that replacing the floor with treadmills is a good way to promote exercise. After increasing his brother's intelligence effectively turns them into obnoxious clones of himself, he uses his tendency to overthink things as part of a trap to revert them to normal.
* ControlFreak: He hates it when things don't go according to how ''he'' thinks they should. At one point, he "gifts" Leonardo a shock collar that zaps him every time he quips, Mikey an inflatable suit that renders him an immobile ball when he flips too much, and Raph a helmet that tries to force him to make plans. He also moans when his brothers get in the way of his science experiments (even when he's the one with SkewedPriorities) and gets frustrated when S.H.E.L.L.D.O.N. stops listening to him as a result of his reprogramming.
* DeadpanSnarker: This incarnation of Donnie has to deal with ''two'' goofball brothers and one knucklehead this time around, and snarks considerably more as a result.
* TheDeterminator: Amazingly, he is this in ''Lair Games'' to the point where he wouldn't let a broken ankle stop him from competing against Leonardo who's always winning 5 years straight. [[spoiler: While he does win against Leo, [[PyrrhicVictory it didn't quite pay off]].]]

* EvilLaugh: Parodied. Rather than simply laughing evilly, he will literally say "evil laugh" verbatim.
* FaceYourFears: Donnie is afraid of beach balls, but after he turns his brothers into overwhelming insufferable geniuses and turns them back, Donnie is forced to use his beach balls to scare his brothers into the exit.
* ForeheadOfDoom: Has quite a big forehead compared to his brothers. He's also the most morally ambiguous sibling.
* FreezeFrameBonus: While crawling away from the group in "Todd Scouts" his shell can be seen bending, which makes sense, as softshell turtles' have somewhat flexible shells.
* FreudianExcuse: He DoesNotLikeMagic and tries to [[ClarkesThirdLaw rationalize]] or 1-up it when he can because, being the smart one, he has used science to justify his place on the team. If magic can do what science (and by extension Donatello) can and better, then where does that leave him?
* GadgeteerGenius: Donnie is always inventing and creating new gadgets and machines, whether it be for convenience or to help their missions.
* GeniusBruiser: He's both an effective ninja and a genius, arguably one of the most competent of his brothers when it comes to accomplishing goals.
* GogglesDoSomethingUnusual: Early in the show, he programmed them to detect mystic energy readings.
* HardOnSoftScience: In ''Mystic Library'', he has this attitude towards geology.
* HeroicBSOD: Had one regarding beach balls in ''Mind Meld''.
* HiddenDepths: ''Bug Busters'' implies that he wants some form of approval and validation for his tech, and is the most vocal about feeling betrayed by Big Mama. In ''Ballad of the Rat Man'', it reveals that Donnie has always craved the positive validation from his own father Splinter, getting excited when Splinter says he's proud of him and feeling betrayed when he found out Splinter lied to him. He also reveals in ''Donnie vs. Witch Town'' that being the science guy is the ''only'' thing he knows, and that he's afraid of being left behind once mysticism can accomplish something that he can't.
* {{Hypocrite}}: In ''Smart Lair'', Donatello tries to guilt his brothers for having reprogrammed S.H.E.L.L.D.O.N. to be biased toward them (to the point S.H.E.L.L.D.O.N. [[GoneHorriblyRight tries to kill Donnie]]). Donatello himself had ''blatantly'' programmed S.H.E.L.L.D.O.N. to be loyal to him, which even S.H.E.L.L.D.O.N. calls Donatello out on.
* InferioritySuperiorityComplex: For all his bragging, Donnie secretly craves validation for his accomplishments, which often impacts his judgement. ''Donnie vs. Witch Town'' has him admit to April that the reason he's so adamant to flaunt his scientific know-how is because he's afraid that being the "science guy" is the only reason anyone ever needs him.
* InfiniteSupplies: Donnie in particular has such futuristic gear, one wonders where he even gets it all and the energy to supply it. Somewhat implied that he swipes whatever usable materials he can from the Junkyard.
* InformedSpecies: He's a soft-shelled turtle, but lacks one of its most distinctive feature, the long snout. It's worth noting, however, that he ''was'' shown with a long snout pre-mutation, so it's possible that the human DNA has something to do with that. With that said, Donnie does possess the most distinctive feature of a soft-shelled turtle: a carapace without scutes. It's the entire reason he wears a battle shell.
* InsufferableGenius: He knows he has a big brain and is proud of it, constantly talking down to others not on the same level of technological expertise, yelling at them when they get in the way of his experiments, and often suffers from SkewedPriorities whenever his ForScience instincts kick in.
* JerkWithAHeartOfGold: He's got a huge ego, and has a tendency to disparage everyone around him. Thankfully, this doesn't stop him from still doing the right thing, and he does sincerely love his family and friends.
* LackOfEmpathy: Downplayed. He's definitely not a psychopath, but is noted to be somewhat unemotional and doesn't always react appropriately to other people's feelings. When S.H.E.L.L.D.O.N. starts acting out, Donnie has a hard time understanding and showing the drone empathy, thinking he should deal with it by permanently locking the restraining bolt as a punishment.
* LargeHam: He's arguably the most flamboyant of the turtles, giddily announcing his excitement to use the super lethal cannons he installed on the Turtle Tank, groaning when his brothers remind him that Splinter is on board the truck they're trying to stop, and happily posing while trying on clothes from the 80s.
* LikeFatherLikeSon: Mikey compared and noticed his temper and parenting being exactly like Splinter as seen in each photo.
** Splinter himself seems to think out of all the boys Donnie is the most like him.
---> '''Donatello:''' (Sing-songs) Oh pu-pah...! If you surrender now, there shan't be any consequences...!
---> '''Splinter:''' ''That is a lie!'' I taught him that one.
* LogicalWeakness: His hi tech bo staff is chock full of useful tools and is as effective as his brothers' mystic weapons, but it still requires a physical power source to actually work. He's also the turtle with a literal soft shell, so he's vulnerable if his tech shell is missing or destroyed (the ''Todd Scouts'' episode shows him building a shell made of tree bark almost immediately as if by instinct).
* LoopholeAbuse: He's to pair with Hypno to either win a chess game together or die, with Donnie as the pieces and the magician, who has no idea how to play, as the one making the moves. After Hypno spends forever trying to decide his first move, their opponent slams his fist down in frustration, knocking over his own king. As this is how people acknowledge defeat in chess, Donnie immediately starts proclaiming that the Yokai has forfeited, allowing his side to win the game by doing absolutely nothing.
* MadLibsCatchphrase: His battle cries are various science terms and references to scientists, like "Entropy!" or "Fibonacci!"
* MadScientist: The guy really wants uranium, and not to mention some of his more questionable inventions.
* MartialArtsStaff: Unlike the others, he keeps his trademark Bō Staff, but he's upgraded it into a more high-tech transforming weapon.
* MiddleChildSyndrome: At one point, Raph implies Donnie has this.
-->'''Raph:''' Donnie, if you don't cut it out with your '''middle child nonsense, I'm gonna SHOVE YOUR HEAD IN THE-'''
* MoralityPet: His brothers are this to him. Without them for him to love and take care of, Donnie would probably stray more into villain territory than anything else. Or, he would least do whatever benefits himself the most without thinking of anyone else.
* MorphWeapon: His bo staff can transform into nearly ''anything'' he needs. Knives, bayonets, saws, flamethrowers, drills, rocket hammers, and many more things (including [[ArsonMurderAndJaywalking a disco ball and a built-in camera for selfies]]). Somehow it's all able to fit inside that thin little bo staff without being impossibly heavy. Lampshaded by Donatello himself, who says he likes to fight the old-fashioned way... with impossibly futuristic tech weapons.
* MrExposition: He enjoys talking at length about his technology and discoveries, which Leo refers to as "speech mode."
* NeverMyFault: He tends to deflect or try to ignore when he makes mistakes, and will rarely admit when he's wrong.
** He blames April for his tech getting stolen by the Purple Dragons in ''The Purple Jacket'', even though he showed them his tech in the first place, and was the only one with any maintained interest in the club.
** In ''Al Be Back'', he [[SelfServingMemory pretends he didn't]] rebuild Albearto due to the murderous rampage the animatronic went on.
** In ''Donnie vs. Witch Town'', despite being shown photographic evidence of April's science fair projects going south when she got help from him, he says that it was [[ImplausibleDeniability probably]] another "teenage mutant ninja Donnie."
* NotSoAboveItAll: Generally, Donnie will be the one looking exasperated at his brothers' antics. But he has his moments where he seems... [[SlasherSmile unhinged]].
* OnlySaneMan: Being the most intelligent of the turtles, he can be this at times. Especially in ''Mind Meld'', where he's the only one to take the mission seriously.
* RobotBuddy: Later creates S.H.E.L.L.D.O.N. who becomes this to Donnie.
* ScienceHero: His staff is a Titanium-made SwissArmyWeapon that he prefers to all the magic ones.
* SelfServingMemory: If he's to blame for an incident, chances are he will be unable to recall it ever happening. When Raph brings up the time Albearto turned evil after Donnie upgraded him, not only does Donnie claim he doesn't know what he's talking about, he acts like he's never even ''heard'' of the animatronic.
* SesquipedalianLoquaciousness: Donnie tends to describe his gadgets using the biggest words possible even when there are much simpler common words to describe the same thing. Leo is usually the one to hurry him to get to the point.
* SinisterSurveillance: Not exactly sinister, but still pretty creepy. Donnie can tap into any security camera in New York, records "everything" and has secretly put trackers on likely each of his siblings. Whenever they start to get suspicious, Donnie dodges the question.
-->'''Leo:''' Wait, does that mean you put trackers on all of us?\\
'''Donnie:''' ...No? No, of course I did... n't.
* TheSmartGuy: And TeenGenius, of course.
* SmartPeoplePlayChess: He goes into the chess-based battle in "Battle Nexus: New York" with confidence... only for Big Mama to turn the tables on him by making ''him'' all of the game pieces.
* SpontaneousWeaponCreation: [[spoiler:After unlocking his Hamato Ninpo, Donnie gains the ability to create weapons and machinery from nothing. This allows him to summon almost whatever he needs in the midst of battle, be it just a hammer or an entire arsenal of heavy artillery]].
* TokenEvilTeammate: Donnie is a borderline example. He occasionally displays violent tendencies, such as wanting to destroy a car his adoptive father was in, uses his brothers for various experiments, and can be quite callous and dismissive towards his family. Despite this, he still loves his family and will ultimately do the right thing.
* TookALevelInKindness: By the end of the series, Donnie is much more outwardly kind and compassionate than at the beginning.
* VitriolicBestBuds: Type 2 with Leo. They snark, banter, and tease each other a great deal, but at the end of the day do love each other very much and are shown/implied to hang out together by themselves many times.
* WellDoneSonGuy: Even when he tries to play it cool, it's plain to see that out of the four brothers, Donnie's the most determined to earn some validation from Splinter.
** It becomes apparent that Donnie is praised so rarely that he craves validation from ''any'' adult he considers "parent-aged". Multiple times he's tricked into helping villains because he views them as parental figures and he later gets into a fight with Leo and Mikey for [[spoiler:Karai]]'s attention after she compliments his tech.
* YouAreBetterThanYouThinkYouAre: Part of the reason why he's such a vocal skeptic about magic and mystical forces (despite his frequent encounters with them) is because he's afraid that his tech-based skills (and by extension, him) would be considered expendable by his family. April smacks some sense into him in ''Donnie Vs. Witch Town'' by telling him that ''he'' matters to her, not his gadgets, and that science and mystic powers work better together.

[[folder:Michelangelo]]
[[quoteright:293:https://static.tvtropes.org/pmwiki/pub/images/mikey_7.png]]
[[caption-width-right:293:Got Mad Skills]]
-->'''Voiced by:''' Brandon Mychal Smith (English), Carlos Siller (Latin American Spanish)

The youngest of the turtles, Mikey is a bundle of cheer and excitement. Styling himself as "Dr. Delicate Touch", he is the most in tune with his emotions and always wants to see the very best in everyone.
----
* AdaptationalComicRelief: [[InvertedTrope Inverted]], oddly enough. While Mikey's still fairly silly, the comedic traits the other characters have taken on means he's no longer ''the'' PluckyComicRelief, with more emphasis put on his artistic talents and [[AllLovingHero high empathy]].
* AdaptationalWeaponSwap: While Michelangelo has been versed in the use of nunchucks, grappling-hooks and chain-scythes in different incarnations, this version also wields a Kusari-Fundo, a chain-based weapon that he uses as a KillerYoYo.
* AdaptationSpeciesChange: Mikey is now a box turtle[[note]][[MythologyGag Though the brothers were previously identified as box turtles]] in the [[Film/TeenageMutantNinjaTurtles2014 2014 film]][[/note]] with the unique ability to fully retract into his shell. He does so a lot when he's in danger or sometimes for an attack.
* AffectionateGestureToTheHead: He is often comforted by pats to the head by his brothers or by April.
* AffectionateNickname: Known mostly by his nickname Mikey, but is also called Michael, Mike (which, ironically enough, [[AdaptationalNameChange was his primary nickname]], in the [[ComicBook/TeenageMutantNinjaTurtlesMirage original Mirage comics]] and the NES and SNES games) , Miguel, and Angelo by his brothers. He is also called Orange by Splinter.
* AgeLift: Downplayed. Mikey is still the youngest of the four but while in previous incarnations, he's technically the same age as his brothers, here he is a year younger than Leo and Don and two years younger than Raph.
* AllLovingHero: He's a sweet and earnest kid who tries to bring out the best in everyone. [[spoiler:That includes Baron Draxum after he finds out that he created the turtles, essentially making him their father. The moment he sees an opportunity to potentially redeem Draxum, he takes it without hesitation]].
* AnnoyingYoungerSibling: While not terribly annoying most of the time due to his mostly amiable personality, he sometimes can come off at this to his older brothers.
* AnOddPlaceToSleep: While not ''terribly'' odd, he's the only one of his brothers to sleep on a hammock than an actual bed. Without a blanket as well (though does seem to do so on occasion).
* TheBabyOfTheBunch: Mikey is often youngest, but being 13 is the youngest the franchise has done yet. While not outright babied most of the time, the others are usually quite friendly with their youngest sibling, offering him pats on the head for comfort, not minding & accepting his sometimes spontaneous hugs, and take extra time to make sure he's safe.
* BadassAdorable: Even though he's arguably the cutest of the brothers, he still is an extremely proficient and powerful fighter.
* BerserkButton:
** Disgracing pizza is a big no for Mikey. The collapse of the brothers' favorite pizza places is one of the fiercest he's ever been.
** Also using cute phrases like pinching cheeks as a threat or destroying cute objects upsets him greatly.
* BewareTheNiceOnes: Lampshaded by Mikey himself. He's usually a nice, peaceful, kindhearted turtle, but push his buttons and he won't hesitate to bite back; mostly played for comedic purposes.
* BewareTheSillyOnes: He's a lovable goofball most of the time. But as shown in ''Many Unhappy Returns'', he can be a force to be reckoned with since his plan to stop [[spoiler:Shredder]] included hurling ''a fully loaded freight ship'' to the face!
* BrutalHonesty: Though he's shown to be gentle and kindhearted, he doesn't seem to hold back when it comes to telling the blunt honest truth (or lie depending on the situation) via his "Dr. Delicate Touch" persona.
* CharacterCatchphrase: "Oh me gosh!"
* CharacterTics: Mikey is often seen climbing and sitting on his brother's shells, sometimes being piggybacked by them. He does this the most to Raph, but he does do it to all of his brothers. He also puts his hands behind his head when he's relaxed.
* CheerfulChild: Mikey, the most childish of the brothers, usually seen with a cheerful grin on his face, no matter what the occasion, even in battle.
* ChildishToothGap: Mikey has an adorable little gap in his set of pearly whites, which enunciates his position as the youngest brother.
* {{Cloudcuckoolander}}: His thought process is a lot different and wilder than his brothers. Downplayed example, he has his SkewedPriorities in ''Donnie's Gifts'', as well as his train of thought during ''The Fast and the Furriest''.
-->'''Mikey:''' Are we gonna need a protractor?
-->'''Donnie:''' No.
-->'''Mikey:''' An abacus?
-->'''Donnie:''' Literally never.
-->'''Mikey:''' (excited) A bag full of sausages?
-->'''Donnie:''' Man, I don't understand how your brain works.
* CombatParkour: While all turtles jump and flip, Mikey does so considerably more than the rest and is quite graceful, if not a bit reckless, when it comes to jumping around. His flips are frequently quoted as his strong point by his brothers and acknowledged by Mikey himself.
* CompetitionFreak: Seems to be a little of this somewhat, eager to beat Leo in ''You Got Served''.
* ConfusionFu: Mikey's Kusari-Fundo makes him fight like this. In real life, Kusari-Fundo's are one of the most unpredictable weapons due to the heavy chain. Mikey's takes it up a notch by having the end of the Kusari-Fundo a sentient mythic fire strong enough to randomly propel Mikey forward. Mikey's random personality compliments this.
* CuddleBug: While all the brothers love their hugs once in a while, Mikey is one whose ''always'' loves accepting and giving lots of hugs, especially [[TheGlomp glomps]]. He's the most physically affectionate of his brothers and also tends to cling to his older brothers when frightened.
* TheCutie: Mikey has a lot more of that 'silly childish humor' than his brothers and seems to just ''love'' cute things like unicorns and puppies. He's also pretty kind-hearted and polite, though can still be considerably childish a lot of the time.
* EpicFlail: His enchanted Kusari Fundo, whose ball can become engulfed in a living fireball to fly around on its own, dragging Mikey with it. He can also use it to snare and toss practically anything regardless of weight, once using it to throw an entire cargo ship by its guard railing at Shredder.
* FurryReminder: Mikey likes to pop into his shell at times when he feels scared or in danger.
* FunPersonified: Mikey's artistic endeavors make him always down to have a good time, seeing beauty in most things.
* HandBehindHead: Seems to be Mikey's {{Character Tic|s}}. He is frequently seen putting his hands behind his head in a relaxed pose.
* TheHeart: Different from most examples in that he's still willing to jump into a fight and show off his moves, but he is also the brother to have a non-combative nature and the least pride at stake in conflicts. He also loves to give compliments to his brothers. He was also the only one with big enough a heart to forgive and even help [[spoiler:Draxum]] despite all he's done.
* HiddenDepths: In ''Breaking Purple'' he's the one who gives Donnie advice when it comes to Shelldon's rebellious personality.
* HorribleJudgeOfCharacter: He has shades of this, though it's PlayedForLaughs. He believes that Meat Sweats is interested in being his friend in ''Nothing but Truffle'', calls Foot Recruit his "frenemy", and tends to look for the best in villains who he thinks are trying to do something he sees as positive even when they're clearly uninterested, such as in ''Origami Tsunami'', when he joyfully thinks Foot Lieutenant is making arts and crafts when he makes an origami soldier. The only time this works in his favor so far has been with [[spoiler:Baron Draxum, whom he helps reform.]]
* {{Keet}}: Mikey is a relatively small, cute, hyperactive, and colorful turtle who just loves to have fun.
* KillerYoyo: Michelangelo's new Kusari-fundo functions like one.
* KillItWithFire: His weapon's magic ability engulfs it in flame, allowing it to be propelled forward with great force but making it difficult to control.
* NeverMyFault: Shows small shades of this sometimes with people other than his brothers.
* NiceGuy: Mikey is very sweet all around, as the series plays up his earnest nature.
* OnlySaneMan: Downplayed due to his own eccentricities, but he serves as a bit of a mediator between his brothers when they're arguing. He and Leo seem to flip-flop between this trope.
* {{Protectorate}}: Being the most infantile of his family and TheBabyOfTheBunch, Mikey's older brothers are usually quite protective of him to the point of being overprotective. Although unfortunately not entirely to his liking, Raphael immediately goes PapaWolf just sensing that Mikey might be in danger. Leonardo is a BigBrotherMentor to him and the two share a special bond. Even the normally arrogant Donatello shows that he has a visible soft spot for Mikey and in the movie there is basically no moment during the battle that he isn't worried about Mikey's safety.
* TeamChef: A big fan of "Kondescending Kitchen" (which stars Meat Sweats), and on Splinter's sick day he wanted a brick oven for making pizza.
* TenderTears: Being the most outwardly sensitive of the Turtles, this happens quite often.
* VariableLengthChain: The length of the chain on his weapon is as long as he wants to be, justified in [[spoiler:both cases]] as being explicitly mystical.
* WeaponTwirling: Due to the nature of his weapon, Mikey often twirls the "ball" part of his Kusari-Fundo, even when idle.

[[folder:April O'Neil]]
[[quoteright:285:https://static.tvtropes.org/pmwiki/pub/images/rise_april.png]]
-->'''Voiced by:''' Creator/KatGraham (English), Azul Valadez (Latin American Spanish)

----
* ActionGirl: She tries to be at least. She's not a major powerhouse or has any training but is very proactive and will charge into battle with her bat. [[spoiler: Splinter does start training her how to fight in "Fists of Furry." Once her bat becomes mystical and she merges with Karai, she easily fights alongside the turtles.]]
* AdaptationalBadass: Like her 2012 incarnation, April is rarely a damsel in distress like her older counterparts. Here, despite being untrained, she's more than capable of fighting alongside the Turtles, even defeating villains like Meat Sweats and Foot Recruit without their aid. She's also much more of a physical fighter, preferring melee combat.
* AmbiguouslyAbsentParent: Despite her being a high schooler, her parents are never seen in full in the show.
* BadassAdorable: She's a cute girl who won't hesitate to take down foes twice her size.
* BadassNormal: She's a normal human but is more than willing to jump into the fray alongside the turtles. She's the one to deal the final blow against [[spoiler: Baron Draxum in the season 1 finale]].
* BatterUp: Her signature weapon seems to be a baseball bat (which in previous incarnations was among Casey Jones's favored weapons). She is shown having a bat in her home. [[spoiler:She also uses a baseball bat to help defeat ''a Shredder-armor wearing Baron Draxum'' in the season 1 finale.]] If she doesn't have it with her, she'll mostly use whatever blunt weapon is on hand. In "Donnie Vs. The Witch Town" [[spoiler: she gets a magically infused bat to fight with.]]
* BespectacledCutie: She's a caring, cute girl with a big heart. Her glasses serve to emphasize her cuteness, but she otherwise starkly averts the "shy and reserved" archetype associated with this trope.
* ABirthdayNotABreak: April is convinced that her birthday is cursed, since unfortunate things just always seem to happen on that day, as shown in "Warren and Hypno, Sitting in a Tree."
* BloodKnight: A mild version, but this April is arguably the incarnation most eager to throw some punches.
* ButtMonkey: In terms of her social life outside of the Turtles; she's not very popular at school, she has a hard time holding a steady part-time job, and almost all her extracurricular activities end up backfiring on her hard.
* CharacterCatchphrase:
** "APRIL O'NEIL!!!!" ala Leeroy Jenkins.
** Also "...this whole situation."
* CharacterTics: If she is forced to summarize the overall strangeness of a plot, she waves her hand and ends her sentence with... ''"this whole situation"''.
* CoolBigSis: In the novelization, April considers the turtles like her brothers. She's also older than the oldest of the bros, Raph, by one year (at age 16).
* CrazyPrepared: She has a crane license just in case she has to hurl cranes at bad guys as shown in ''Many Unhappy Returns.''
-->''(mockingly)'' "Why'd you get a crane license, April?" ''(normal)'' '''BECAUSE THIS!!!!'''
* DisabledInTheAdaptation: In contrast to her past incarnations, this April requires glasses.
* DressingAsTheEnemy: Has gone undercover a couple of times in Foot Clan threads.
* EmpoweredBadassNormal: She becomes this [[spoiler:after Karai transfers her essence into her, giving her access to Hamato Ninpo]].
* {{Fangirl}}: A big one of Warren Stone ever since she was a little kid.
* FreeRangeChildren: She's mentioned having parents, but they're never seen in full, or even mentioned about how they might've reacted to their daughter being absent for days at a time or their apartment getting wrecked (directly and indirectly) by the Turtles several times.
* FriendlessBackground: She doesn't appear to have a ton of friends outside of the turtles, which she can be self-conscious about--in fact, prior to befriending Sunita in "Operation: Normal," arguably the closest she has to a friend outside of the turtles is Dale, a weird classmate of hers who appears to have a crush on her (which April clearly doesn't return).
* GenkiGirl: She's a very energetic and spunky girl always raring for a fight.
* ImprovisedWeapon: She engages in ProducePelting in ''The Gumbus'', using a sausage as an arrow.
* IntrepidReporter: The movie shows she majoring in journalism in university and breaks into a lab at night to investigate rumors that the school is secretly creating a powerful deforestation bomb for foreign governments. The rumors turn out to be true, [[spoiler:and the samples of the substance she nabs for evidence prove to be the only effective weapon against the Krang, burning a hole straight through Krang Two's eye]].
* LeeroyJenkins: Practically rushes headlong into danger in the pilot to rescue Mayhem with no plan whatsoever other then just flail wildly. Her battle cry is even similar to Leeroy's by yelling out her own name.
-->'''Mikey:''' [[ShoutOut Oh me gosh, she just ran in!]]
** Her FearlessFool trend extends to her appearance in ''The Gumbus'', where she's laughing her head off while Leo and Mikey screech in fear.
* NightmareFetishist: Her absolute glee about ghosts during ''The Gumbus'' shows that she has some interesting tastes.
* OnlySaneMan: Being a regular human often gives her a more grounded reaction to the turtles' usual antics.
* RaceLift: This incarnation is not a Caucasian redhead, but an African-American redhead.
* SassyBlackWoman: When in a verbal sparring match, she really cranks the snark up. And sometimes while she's physically fighting too!
* {{Scapegoat}}: In "The Purple Jacket", Donnie blames April for the Purple Dragons stealing his tech to commit crimes with, despite her having told him not to get involved with them and his getting mixed up with the group being entirely his own fault. April is less than impressed with his behavior.
* StraightManAndWiseGuy: She tends to play this role to the turtles, particularly towards Donatello.
* SignificantWardrobeShift: After [[spoiler: Karai transfers her essence into April]], her outfit transforms into one that subtly resembles [[spoiler: Karai's robes]].
* TomboyAndGirlyGirl: The Tomboy to Sunita's Girly Girl.
* WeirdnessMagnet: Lampshaded by Leo in "Operation: Normal", where she attempts to have a normal day with a new friend. [[spoiler: Of course, it turns out her new friend isn't human.]]
* WhyDoYouKeepChangingJobs: She never has the same job twice throughout the first season. Became a rather critical plot point in 'Shadow of Evil' where she accidentally finds herself working at an evil shoe store run by The Foot Clan.

* AmbiguouslyEvil: [[spoiler:He's an agent sent to keep an eye on Baron Draxum, but it's hard to tell if he's really benevolent or not.]]
* TheEndingChangesEverything: A single flashback in the Season 1 finale reveals [[spoiler:that he's actually sent to spy on Baron Draxum.]]

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shelldon.png]]
-->'''Voiced by:''' Greg Cipes

Also known as just Shelldon. Donnie's personal robot and helper.

----
* AIIsACrapshoot: Starts out pretty nice and helpful to the turtles, but Donnie purposely programmed Shelldon to favor him over his brothers. When Leo, Raph, and Mikey mess with his programming, it reverses and favors the other turtles over Donnie instead, but Shelldon decides that he wants to ''replace'' Don instead of just favoring the others. Shelldon's second incarnation averts this and is shown to be incredibly helpful.
* ArtificialIntelligence: He's a sentient program that runs most of Donnie's tech.
* BrattyTeenageSon: He goes through this phase in "Breaking Purple," to the point he runs away from the lair after one too many fights with Donnie. Unfortunately, he runs into the Purple Dragons, who are more than happy to manipulate him.
* CharacterizationMarchesOn: He initially behaves like a butler before being altered by the other Turtles, which makes him behave much more rebelliously and attempt to kill Donatello. Later appearances use a personality similar to his second one, but [[BrattyTeenageSon brattier]].
* CuteMachines: While not as adorable as most examples, Shelldon sports adorable round eyes and his second incarnation has his mouth upturn in what looks like a smile. His second incarnation looks like a purple sea turtle.
* DeadpanSnarker: Seems to have adopted some of this attitude, probably partly in due to his creator being the master of this.
* KillerRobot: After Leo, Raph, and Mikey mess with Shelldon's programming, he tries killing Donnie and replacing him as the turtles' brother. He was fortunately decommissioned and was rebuilt as a much more loyal and helpful companion.
* MythologyGag: In the series finale, he shifts to a more humanoid body, which gives him a resemblance to a purple Metalhead, particularly the 2012 version built by Donatello. He also shouts "Booyakasha!", the 2012 Mikey's catchphrase.
* RobotBuddy: He exists to help the turtles, though Donnie primarily relies on him as a personal assistant.
* RobotMaid: Was one to the turtles and Splinter. It was his original primary purpose when Donatello built him. It is unknown whether or not Shelldon still has this role after being rebuilt and remodeled by Donnie. He still serves somewhat of this purpose at least in Donnie's lab.
* SurferDude: Not ''really'' one, but he adopts the all too familiar Surfer Accent after Leo, Raph, and Mikey mess with his circuitry. Donnie opts to keep this accent on Shelldon's second model, surprisingly enough.
* WhatHappenedToTheMouse: In the Season 2 Finale, he was destroyed by Shredder while attempting to protect Karai. His loss and character isn't mentioned again for the rest of the finale. It's unclear if Donnie still has a backup of him or if he's destroyed for good. He also isn't brought up in the movie.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tumblr_ppwzby3ixs1wrn77u_540.png]]
-->'''Voiced by:''' Creator/RobPaulsen
A non-aggressive paper foot ninja affectionately nicknamed "Buddy" and serving as a sparring partner for Raph.

----
* AffectionateParody: To Frankenstein if it wasn't obvious (also Sloth from The Goonies in term of personality and technically was a member of the bad guys).
* ChuckCunninghamSyndrome: He completely disappears from the series after "Flushed, but never Forgotten".
* GentleGiant: He's rather gentle-natured despite his predisposition toward fighting, and is quick to forgive the Turtles despite Raphael hurting his feelings and Leonardo, Donatello, and Michelangelo's prior intent to kill him.
* GoodCostumeSwitch: [[DownplayedTrope A fairly mild case]], but once Leonardo, Michelangelo, and Donatello start defending him, Michelangelo rubs off the Foot Clan symbol from Frankenfoot's face and draws this series' incarnation of the Turtles' insignia on his face, cementing him as one of their allies.
* LogicalWeakness: He was put back together by Raphael, and thus, ''very'' easily falls apart even from rather weak blows, which results in him having to constantly be put back together. That being said, he ''does'' seem to have the ability to fix himself with some sort of magic, but doesn't know how to properly use it.
* SuddenlyVoiced: He's notably the first Origami ninja to show the ability to speak, even if in a rather limited, rudimentary way.

[[folder:Casey Jones]]
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/rise_tmnt_casey.png]]
-->'''Voiced by:''' Creator/HaleyJoelOsment
The Turtles' future apprentice, having travelled back to the past to [[SetRightWhatOnceWentWrong help them prevent the armageddon]] threatened by the Krang.

----
* AdaptationalAngstUpgrade: ''Hoo-boy''. The typical Casey Jones is a StreetPunk that took up vigilantism (though whether he was pushed into it by a tragic backstory or not differs), only to wind up involved in the Turtles' insane adventures through chance. This version comes from a BadFuture where he lived his entire life on a terraformed Earth, surviving on rats and struggling to survive against an InvincibleVillain, being sent to the past after everyone he ever knew and loved died horribly.
* AdaptationalNiceGuy: Prior incarnations of Casey Jones are generally [[JerkWithAHeartOfGold rough around the edges but good people]], but this one is much more polite and kinder, only really being kind of a jerk when Leonardo being dangerously careless [[spoiler:gets them trapped under rubble, after which he tells Leo outright that if he doesn't think about the consequences of his actions, then he and his brothers will end up dying like their future selves]].
* AdaptationRelationshipOverhaul: Casey has a strong bond with the future Leonardo in the film, which gradually develops into a strong one with the present day version after being [[BrokenPedestal disappointed]] at how shallow and egotistical the teenaged one is. While Leonardo and Casey are allies in prior incarnations, Casey and Raphael are usually the ones with the closest connection to each other instead. This makes more sense when you consider the possibility that he doubles as a GenderFlip of Shadow Jones, rather than a straight and narrow adaptation of the Casey Jones character.
* AdaptationalWeaponSwap: Downplayed. He has Casey's traditional hockey stick weapon, but it's noticeably more mechanical with a chainsaw function.
* AgeLift: Usually a contemporary of the Turtles. Here, he grew up while they were in their twilight years.
* CassandraTruth: His initial claims of hailing from a BadFuture are initially laughed off by the Turtles, April, and Splinter. [[SubvertedTrope He eventually manages to convince them]], however, when he mentions those aliens are the Krang, whom Splinter has heard of.
* CompositeCharacter:
** While he has the name, hockey stick, and mask of prior incarnations of Casey Jones, his backstory of being a descendant (albeit in this incarnation being specifically [[spoiler:the son]]) of the original Casey Jones, along with his hero worship and IntergenerationalFriendship with the Turtles, is more similar to Cody Jones from [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2003 show's]] ''Fast Forward'' era.
** Alternatively, he could be considered one of Shadow Jones from the Mirage and Image comics and Casey Marie Jones from ''[[ComicBook/TeenageMutantNinjaTurtlesTheLastRonin The Last Ronin]]''.
* DecompositeCharacter: Many of his traits were divided up between April O'Neil and [[spoiler:the Foot Recruit]], long before his proper appearance in the BigDamnMovie.
* DisappearedDad: While the identity of his mother is established at the end of the movie, his father is never spoken of.
* GenderFlip: While he, on the surface, appears to be a TruerToTheText iteration of Casey Jones in contrast to [[spoiler: his mother Cassandra]], who borders heavily into InNameOnly territory, one could make the argument that he's actually this trope for the more obscure TMNT characters Shadow Jones from Mirage & Image comics and Casey Marie Jones from ''The Last Ronin'' series. For both characters, he's the child of each series respective iterations of [[spoiler: Casey Jones I]]. For Shadow specifically, he's also the ninjutsu apprentice of Leonardo. For Casey Marie Jones specifically, he's named after the previous iteration of Casey within his installment, like how she's named after the late Casey Jones of ''The Last Ronin''.
* HarbingerOfImpendingDoom: Shows up from nowhere attempting to convince the Turtles that there will be a future apocalypse they have to prevent. Yep, definitely counts as one.
* InnocentlyInsensitive: A small one when [[spoiler:Raph sacrifices himself to save Leo.]] He's more concerned about the [[spoiler:portal key.]] He quickly apologizes.
* NomDeMom: [[spoiler:Assuming his mother, Cassandra Jones, didn't marry someone with the same last name (if she married at all), he gets his last name from her rather than whoever his biological father could be.]]
* SetRightWhatOnceWentWrong: Why he was sent back to the past by the future Leonardo; to prevent the Krang from committing TheEndOfTheWorldAsWeKnowIt.
* SignificantNameOverlap: PlayedWith, as [[spoiler:The Foot Recruit's full name of 'Cassandra Jones' means that Casey is a nickname that can be attributed to her, but for this future son of hers, it seems to be his actual name]].
* SuspiciouslySpecificTense: When recalling the future exploits of the Turtles, he talks about Leo and Mikey using present tense, which makes sense since they only died recently, but Donnie is referred to using past tense.
* TruerToTheText: He's a relatively more comic-accurate version of Casey Jones than the [[spoiler:Foot Recruit]]; aside from his obvious XY chromosomes, he also wears and wields the signature hockey mask and stick.
* WalkingSpoiler: Sorta, in that his existence would indicate that he's the present-day VigilanteMan human fighter that allies with the Hamato clan eventually in the present, but he's actually the future descendant of said character sent back from a BadFuture to prevent TheEndOfTheWorldAsWeKnowIt, and the actual present-day Casey Jones was revealed to be [[spoiler:The Foot Recruit, [[GenderFlip Cassandra Jones]], who also happens to be his mother.]].

!!Past clan members
Historical members of the Hamato Clan.

[[folder:Hamato Sho]]
-->'''Voiced by:''' [[Creator/MatthewYangKing Matt Yang King]]

Grandfather of Hamato Yoshi, and the one who raised him after his mother left.
----
* IdenticalGrandson: Essentially looks like a human version of Splinter's rat form.
* RetiredBadass: Since all members of the Hamato clan have a duty to stand watch against the return of the Shredder, Sho presumably is a skilled fighter.
* UnwittingInstigatorOfDoom: While his motives were at least in the right, he was far from an ideal parental figure for Yoshi. His strict insistence on tradition caused him to resent his family and [[spoiler:leave the clan to pursue a film career as Lou Jitsu]], which made him woefully ill-prepared when he realized the Shredder was very much a real thing.
[[/folder]]

[[folder:Hamato Atsuko]]
-->'''Voiced by:''' Keiko Agena

Mother of Hamato Yoshi, who was forced to leave her son to perform her duties to the Hamato clan.
----
* BackupFromOtherworld: [[spoiler:Her spirit appears to aid Splinter and the turtles in overcoming the Shredder's power in the finale.]]
* DaddyHadAGoodReasonForAbandoningYou: Atsuko had to leave her son in order to stand guard against the Shredder's return, something that left Yoshi with a resentment towards the family and its traditions that led him to abandon the Hamato clan.

[[folder:Splinter's Ancestor ('''Unmarked Spoilers''')]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/hamato_karai_rise.jpg]]
-->'''Voiced by: '''Creator/GwendolineYeo

Splinter's ancestor, Karai, who finds her way in the modern day in the four-part series finale.
----
* AdaptationalHeroism: Karai in most incarnations is often loyal to the Shredder above all else, albeit tending to become [[ConflictingLoyalty reluctant]] down the line. Karai is firmly an opponent of the Shredder in this incarnation, and starts out helping the heroes.
* AgeLift: She's usually the Turtle's contemporary in other incarnations, but is their ancestor in this incarnation.
* BarrierMaiden: She was keeping Shredder's will sealed away in the Twilight Realm.
* CanonCharacterAllAlong: She's shown as the mythical figure that originally defeated the Shredder throughout the series, first appearing in "Shadow of Evil" unnamed and finally being seen on-screen in the present day in "E-Turtle Sunshine of the Spotless Mind", with "Shreddy or Not" immediately afterward revealing that she's actually this series' incarnation of Karai.
* DecompositeCharacter: Many of Karai's traits in other incarnations, such as her ConflictingLoyalty to the Shredder and nature as his second-in-command, are given to the Foot Recruit.
* DisappearsIntoLight: She fades away into glowing green light after transferring her essence into April.
* EarlyBirdCameo: She's shown unnamed in "Shadow of Evil" as Splinter relays the Shredder's myth.
* FamilyOfChoice: She readily sees and claims April as part of the Hamato Clan.
* LastEpisodeNewCharacter: She's introduced in the series finale as an important part of the series' lore.
* NiceGirl: Despite her irritation that Hamato Yoshi shirked off training his sons and not knowing Hamato Ninpo, she readily accepts that Splinter and the Turtles are her family despite how unusual it is that they're mutants.
* NotQuiteDead: She seemingly killed by the Shredder after he discover the turtles' lair in her debut episode, but Karai manage to transfer her essence into April before dying. Even Shredder himself is surprised when he found out about this.
* RelatedInTheAdaptation: Similar to the 2012 series, this version of Karai is the Shredder/Oroku Saki's daughter, except biologically and not just by adoption. She's also related to Splinter again, but instead of his biological daughter she's his distant ''ancestor''.
%%zce* SamuraiPonytail: Her hair is clearly tied in one.
* SpiritAdvisor: Becomes one for April after transferring her essence into her.
* SupernaturallyYoungParent: She did not age while sealing the Shredder's will in the Twilight Realm, and so remains in her physical prime while her distant descendant Splinter is middle aged. The Turtles still call her "Gram-Gram".
* TruerToTheText: More well-known incarnations of Karai have her as a younger women who is related to the Shredder in some way and has varying degrees of conflicting loyalties towards him, often fighting with the turtles as often as against them. ''Rise'' Karai is a slightly older adult woman who, while still Oroku Saki's daughter, is firmly on the side of the turtles and has nothing to do with the demonic entity her father became. This is actually closer to the comics in which she debuted; despite a slightly tense neutral first meeting, Karai never battles the Turtles or becomes their enemy, and has no relation to the Shredder whatsoever.
* WalkingSpoiler: She plays a major part in the series finale, helping the Turtles discover their Hamato Ninpo and disclosing a lot of lore behind the Shredder.

!!The Evil League of Mutants
[[folder:Baron Draxum]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/barondraxum_1.png]]
->'''Voiced by:''' Creator/JohnCena [EN] (Season 1), Creator/RogerCraigSmith [EN] (Season 2), Raúl Anaya (Latin American Spanish)

A sheep-like {{Youkai}} warrior and alchemist from the "Hidden City". He is also known as the "Maker of Mutants". As the self-proclaimed protector of all yokai-kind, Baron Draxum seeks to mutate humans into mutants.
----
* AffectionateNickname: Mikey and April call him "Barry" [[spoiler:once he steps down from being a villain.]]
* AmbiguouslyGay: In a flashback Draxum is seen ogling Lou Jitsu, who's striking a dashing pose with his shirt torn open. [[spoiler:Draxum is also considered to be the Turtles' second father, and it's implied that he still has a fondness for Splinter]]. He also doesn't respond to Big Mama's flirtation as she expected, though that could just be him wanting to keep things on a business level.
* AntiVillain: He's not really antagonistic towards the Turtles, and his goals seem to have the aim of the protection and betterment of youkai kind. However, he lacks empathy for humans and seems to be plotting genocide by conversion.
* ArchEnemy: For Splinter/[[spoiler:Lou Jitsu]] for being the one who mutated him and the Turtles, costing him his chance at a life outside of the Battle Nexus.
* ArcVillain: The biggest villain and FinalBoss of the first season before having a HeelFaceTurn in the second.
* BeautifulAllAlong: [[spoiler:Underneath the mask he's quite handsome, at least by human standards]].
* BeingGoodSucks: [[spoiler:In the series finale, he briefly complains that life was a lot easier when he didn't like the Turtles or Splinter, but still finds himself having to stop Shredder from simply killing Splinter. However, this is averted as [[FakeDefector it's simply just a ploy to ambush Shredder]] and he still genuinely cares about them either way without any strings attached.]]
* BigBadEnsemble: He's one of the major antagonists of the series, the other being Big Mama. Draxum is responsible for creating the Oozesquitoes [[spoiler:and the Turtles]], which will go on to create several villains of the Turtles' RoguesGallery, while Big Mama wishes to use said mutants as contestants for the Battle Nexus.
* BigBadWannabe: [[spoiler:He's ultimately used as a pawn by the Foot Clan to revive the Shredder, who proceeds to depower and upstage him as the main villain.]]
* BrutalHonesty: When asked if mutation would hurt by a pizza delivery boy who'd stumbled into his hidden city, he responded by telling him that if was doing it right, [[BluntYes Yes.]]
* CardCarryingVillain: He calls his VillainTeamUp the "Evil League of Mutants".
* CastingGag: John Cena voices a villain who has the ability to turn invisible in reference to Cena's [[Memes/{{WWE}} "You can't see me"]] catchphrase and the memes surrounding it.
** Him being a villain could be seen as one. Online WWE fans have been very vocal in their desire for John Cena to undergo a FaceHeelTurn, but for more than a decade, he's been the same uncomplicated good guy. [[spoiler:There's also irony to be found in the fact that Baron Draxum makes a HeelFaceTurn after Cena stopped voicing him.]]
* CharacterDevelopment: [[spoiler:By the end of "Repairin' the Baron", he seems to be trying to make a genuine effort to live alongside the human race. Also, through no small effort on Mikey's part, Draxum has gradually been reconciling with the TMNT family, proving to them that he's a changed man through heroic, selfless acts.]]
* TheComicallySerious: He's got a fairly serious personality, but has his fair share of comedic moments, often from [[NotSoStoic when his stoicism is broken]]. Case in point:
--> '''Big Mama:''' Scrambulent to see you again, Baron Draxum, but you really must learn to use the ''dimbly door''.
--> '''Baron Draxum:''' ''You'' must learn to use ''real words''!
* ChuckCunninghamSyndrome: Inexplicably the [[spoiler:only major ally of the Turtles]] fully absent in ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtlesTheMovie'', while [[spoiler:even Cassandra makes a cameo appearance]] he doesn't even gets a mention or picture of him brought up.
* CurbStompBattle: He utterly trounces the turtles during their first battle despite their best efforts. Donnie is the only one who manages to get a hit in, and that was by complete accident as Draxum was blindsided by Donnie's out-of-control staff.
* CrushFilter: When he sees the turtles for the first time, this filter is applied over them. It's more him marveling at the success of his experiment though.
* DarkMessiah: He has proclaimed himself as the Protector of Mutantkind. His means of doing so involves plotting genocide on the human populace via conversion. [[spoiler:After obtaining the Shredder armor, he decides to just eradicate the human race the old-fashioned way.]]
* DecompositeCharacter: [[spoiler:His personal enmity with Splinter/Hamato Yoshi is similar to previous incarnations of Shredder and Splinter, both of whom had never met in this continuity due to the Shredder being a centuries-old demon. He also briefly controls the Foot Clan, and tries to become the Shredder, but ultimately fails due to [[EvilIsNotAToy underestimating]] how dangerous both the group and armor are.]]
* DiscOneFinalBoss: Draxum is initially introduced as the main villain of the series, but by mid-Season 1, the Foot Clan take over as the main antagonists, with Draxum working with them. [[spoiler:Even taking over the Clan seems to have been part of their plan, with their plan to have Draxum wear the armor [[UnwittingPawn so that it'll eat his life force]]. By Season 2, he's no longer the main villain, and [[HeelFaceTurn ends up joining the heroes]] too.]]
* EmperorScientist: The head of an underground mutant city and an alchemist to boot.
* EvilCounterpart: He seems to be a bit of one to Donatello, having a fixation on his scientific pursuits that borders on unhealthy. He even gets a CrushFilter when seeing the Turtles for the first time, apparently brought to tears by the perfection of their mutations.
* EvilVersusEvil: Baron Draxum and Big Mama don't get along with Big Mama wanting to use Draxum's Oozesquitoes to make more warriors for her Battle Nexus. Draxum on the other hand wants to use them to get rid of the "human problem" and is not pleased that Big Mama is using his Oozesquitoes.
* EvilIsHammy: John Cena brings a lot of his showmanship to Draxum. Even at his most serious, his every word is a dramatic declaration. And that's not getting into him going full-ham while singing the solo for "Warring Warrior Scientist".
* EvilIsNotAToy: [[spoiler:He underestimates the power of the Shredder's armor, trying to take its power for himself, only to end up [[{{Irony}} having his own life force drained]] as he's spat out. Later on in "Air Turtle", Draxum is on the other side of this trope when he repremands Leonardo for using a dangerous mystic artifact to enhance the abilities of a failing basketball team (which ends up turning the players into demons).]]
* EvilSoundsDeep: Again, courtesy of John Cena, who gives him a very booming voice. It remains even after Roger Craig Smith takes over the role [[spoiler:(although Draxum makes his HeelFaceTurn by the time Smith replaced Cena)]].
* EvilutionaryBiologist: His plans for mankind involve transforming them into mutants with his Oozesquitoes.
* ExpressiveMask: It's revealed in ''Repairin' the Baron'' that he's been wearing a fully-encompassing helmet the entire time, one that happens to have eye holes that are capable of emoting. [[spoiler:It falls off and breaks at the end of the episode as he saves the lives of a human woman and her child, symbolizing his HeelFaceTurn]].
* FakeDefector: [[spoiler:He complies with the Shredder's demands in the series finale, and says that he always planned on betraying Splinter and his family. It turns out to be a ploy to try and ambush Shredder that is doomed the moment he enacts it, and reaffirms he's genuinely changed.]]
* GeniusBruiser: An intelligent alchemist responsible for creating the Ooze, and is no slouch in combat, easily beating the less experienced turtles. Huginn and Muninn call him a "Warring Warrior Scientist" in their song.
* GoodCostumeSwitch: [[spoiler:His mask falls off and shatters on the ground while trying to save two humans in "Repairin' The Baron", which seems to cement his HeelFaceTurn. It's very telling that Draxum doesn't redon his original armor after this; instead, his outfit is now entirely nonthreatening, consisting of a kimono and a hairstyle very similar to Splinter's.]]
* GreenThumb: He is able to summon large purple vines for a variety of purposes, such as strangulation, transportation, and even making a [[{{ChainsawGood}} chainsaw]] for some reason.
* HeelFaceTurn: [[spoiler:At the end of "Repairin' the Baron", he decides to attempt to live among the humans rather than try to destroy them after a lot of coaxing from Mikey. He still hates humans, but seems to be making a greater effort to tolerate them. Later on in "Hidden City's Most Wanted", Draxum finally reconciles with Splinter, apologizing for his past misdeeds against the TMNT family before giving himself up to the Hidden City police so that Splinter and Michelangelo can escape (Splinter and Mikey return the favor and bust Draxum out of prison later along with the rest of the TMNT family who had each also gotten arrested during their own various misadventures in the city). In "Battle Nexus: New York" Draxum risks his life several times trying to free the citizens of New York from a mystic artifact that Big Mama had trapped them all in.]]
* HowTheMightyHaveFallen: [[spoiler:He's living in an apartment room unable to do anything but shout empty threats at people come his return in "Repairin' the Baron", and that was after Mikey originally found him homeless on the streets. Due to the Shredder draining his life force, he can't even manifest his vines, at least not until the end of the episode. Sometime after his HeelFaceTurn, he regains his old strength, allowing him to manifest his vines easily once again.]]
* {{Jerkass}}: Draxum is very blunt and rather uncompromising, and also casually ruins the lives of people he comes across. [[spoiler:After his HeelFaceTurn, he starts [[JerkWithAHeartOfGold warming up]] to the Turtles and humans, although not by much.]]
* JerkassHasAPoint: [[spoiler:He tells Splinter in "Hidden City's Most Wanted" that he wouldn't even ''have'' his sons if it weren't for Draxum experimenting on him, which Splinter ends up agreeing with.]]
* KarmaHoudini: [[spoiler:Zig-zagged. While Draxum's is unable to return to the Hidden City and is forced to live on the streets of New York, he's never arrested for his crimes against humanity and Yokai-kind due to Mikey and his family helping him on account of Draxum creating the turtles and Splinter, i.e. him being family.]]
* LackOfEmpathy: He doesn't really have very much regard for human life, with many having their lives ruined due to being mutated by his Oozesquitoes, and had no qualms with manipulating the Foot Recruit to [[spoiler:take over the Foot Clan]]. [[spoiler:Even after his HeelFaceTurn, he rules the cafeteria with an iron fist, and still seems to want to dabble with Oozesquitoes before April tells him to knock it off. He also tells Splinter that he gave him purpose by using his genes to create the Turtles in "Hidden City's Most Wanted", trying to deflect that he ultimately destroyed any chance of Splinter returning to his old life, although Draxum does apologize for his actions. He also plainly states, when Splinter says that he doesn't want the Turtles seeing some of his most sensitive memories in "E-Turtle Sunshine of the Spotless Mind", that that isn't ''his'' problem.]]
* MookMaker: He apparently created the Ooze, and the Oozesquitoes as a means of distribution. He's also capable of summoning a large mutant to battle the turtles for him in the pilot.
* MoralLuck: [[spoiler:This is the crux of why Mikey considers him family. If he hadn't mutated Splinter and the turtles, the turtles wouldn't exist and would never have become a family. Draxum also argues that Splinter's life is actually better now than it was before he had his sons, which Splinter eventually accepts. That said, Mikey does acknowledge that he didn't mutate them for the right reasons and Draxum does eventually apologize to Splinter for doing so.]]
* MyGodWhatHaveIDone: [[spoiler:The look on his face when beholding the reborn Shredder at the end of Season 1 ''screams'' this as he realizes that, in his paranoia towards humans, he wound up unleashing what might be the ''true'' destroyer of Yokai-kind.]]
* NotSoAboveItAll: Barring his [[TheComicallySerious stoic reaction]] to most things that annoy him, he decides, after Huginn and Muninn flatter him enough, to join in on the VillainSong in "The Evil League of Mutants".
* ObviouslyEvil: He looks borderline demonic, has a deep voice, and outright tells a teenager he's going to mutate that it will hurt. [[KickTheDog If he's doing it right]].
* OOCIsSeriousBusiness: The fact that he casually swats away an Oozesquito and mostly ignores fighting the Turtles in "Shadow of Evil" tips the Turtles off that Draxum might be planning something big.
* ReformedButNotTamed: [[spoiler:Even after he decides to reconsider his campaign against the human race, he still retains much of his ruthless and prideful personality. When he takes up a job in the human world as a cafeteria worker, he runs his cafeteria more like a boot camp, where even the most minor of infractions warrant the threat of physical violence. He also hasn't completely given up on turning people into mutants using Oozesquitoes.]]
* SelfFulfillingProphecy: [[spoiler:He wants to stop the threat to youkai kind...only to find out too late that ''he'' was the one who caused it by teaming with the Foot Clan and letting them resurrect Shredder.]]
* SurroundedByIdiots: He gives off this vibe in all of his interactions. Not surprising given he's more competent and serious than any other villain in the show. [[spoiler:Or so he thought. The goofier tendencies of the Foot Lieutenant and Brute keep him from realizing that they're manipulating him into resurrecting the Shredder.]]
* SuspiciouslySimilarSubstitute: He's an armored villain whose actions [[spoiler:contributed to ruining Hamato Yoshi's life, which also resulted in the creation of the Turtles]], similar to the Shredder. Downplayed after Season 2, where [[spoiler:he becomes heroic and he and Splinter eventually bury the hatchet.]]
* TerrifyingRescuer: [[spoiler:His appearance scared the woman and child he tried to rescue, but they soften up to him after he saved them]].
* ThickerThanWater: [[spoiler:Upon finding him living on the streets homeless, Mikey decides to help him get his groove back and try to turn him around on his opinion on humans in ''Repairin' the Baron'' on account of him being the turtles' creator. Note though that this is pretty much ''only'' Mikey's opinion of the guy for much of the episode until Draxum's HeelFaceTurn at the end.]]
* ThirdPersonPerson: He will occasionally refers to himself in the third person, usually when making a BadassBoast.
-->'''Draxum:''' Baron Draxum does not surrender!
* TokenEvilTeammate: [[spoiler:Even after joining the Hamato Clan, it does very little to quell his [[LackOfEmpathy inability to relate to other people]], he didn't give up on experimenting with Oozesquitoes until April told him to knock it off, and even when acting heroically tends to use unscrupulous tactics.]]
* UnreliableNarrator: His memories of [[spoiler: Lou Jitsu]] paint the man as [[BloodKnight a fierce warrior who enjoyed his time in the Nexus]]. The truth was less so.
* UnwittingPawn: [[spoiler: The Foot Lieutenant and The Foot Brute manipulated him into donning the Shredder Armor over the course of the first season, empowering the Shredder with his life energy to help the ancient demon revive.]]
* VillainExitStageLeft: [[spoiler:He manages to use his remaining strength to escape through a portal during the Shredder's resurrection while the Foot are distracted. Though considering Muninn and Huginn are shown searching for new employment in a following episode, he never returned home.]]
* VillainousCheekbones: As suggested by his helmet shape, he has these. [[spoiler:Ironically, they only get put on full display after he's undergone a HeelFaceTurn.]]
* WalkingSpoiler: The extent of his history with the Turtles and everything that happens to him post Season 1 reflects some massive changes and revelations within the story.
* WorthyOpponent: He holds [[spoiler:Lou Jitsu aka Splinter]] in high regard for his fighting abilities.
* WeCanRuleTogether: He wants the Turtles on his side, and offers to train them in the pilot. This is of course rejected. [[spoiler:Poetically enough, ''he'' eventually ends up joining ''them'']].
* WellIntentionedExtremist: [[spoiler:Upon hearing a prophecy about the end of youkai kind, Draxum is on a one-man quest to stop said threat. Unfortunately, he assumes that said threat is humanity...]]

[[folder:Huginn and Muninn]]
->'''Voiced by:''' Creator/TimSimons (Huginn), Creator/SamRichardson (Muninn)

Two gargoyles that are perched on Baron Draxum's shoulders.
----
* HeterosexualLifePartners: Huginn and Muninn have been close friends since their bootcamp days.
* {{Jerkass}}: Huginn seems to delight in tormenting and frightening others, as shown by his only vocalizations during his first appearance being malicious laughter. This aspect is downplayed in later episodes in favor of his friendship with Muninn.
* MythicalMotifs: Huginn and Muninn were named after the ravens perched on Odin's shoulders who flew around the world and whispered knowledge into Odin's ear. Although [[IronicName neither are very bright]].
* NiceJobFixingItVillain: "Goyles, Goyles, Goyles" reveals that [[spoiler: Huginn and Muninn accidentally destroyed Draxum's mutagen supply in their attempt to assist him in his battle with Lou Jitsu. The spilled mutagen not only created Splinter but delayed Draxum long enough for the turtles to grow and face him in the present.]]
* OutOfFocus: They only show up once in Season 2 in "Goyles, Goyles, Goyles" (which [[ADayInTheLimelight headlines]] them), due to most of their interactions being tied to Draxum, [[spoiler:who went into hiding after Season 1, and later [[HeelFaceTurn became allied with the heroes]]]], and [[WhatHappenedToTheMouse never appear again afterward]].

[[folder:Meat Sweats]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/rise_of_teenage_mutant_ninja_turtles_meat_sweats_nickelodeon_6.jpg]]
->'''Voiced by:''' Music/JohnLydon (English), Miguel Ángel Ghigliazza (Latin American Spanish)

A former celebrity chef named Rupert Swaggart until he was bitten by an oozesquito and mutated into a pig, Meat Sweats would like nothing more than to have the turtles for dinner... literally.
----
* AssimilationBackfire: This happens with him in "Nothing But Truffle" twice.
** Absorbing Todd's unique skill backfired on him and made him a nice and friendly person.
** And finally [[spoiler:absorbing the Were-Tree gives him a weakness to silver, even with the advantages]].
* AsLongAsItSoundsForeign: Meat Sweats talks with an accent that tends to fluctuate with each line. Typically, he sounds like an odd mix between Irish and German, but he also has a tendency to switch to British, French, and at one point even begins speaking like ''a pirate''.
* BizarreAlienLimbs: Those gloves he wears actually cover up the fact that he doesn't have any real hands anymore. When he removes them, his arm splits into several tentacles, which can be used to grab things like normal hands or [[EnergyAbsorption absorb the energy]] of whatever he touches (as well as taste it, apparently).
* CharacterCatchphrase: "Unleash the flavor!"
* EmbarrassingFirstName: Splinter considers his this.
-->'''Splinter:''' You name is "Meat Sweats"?!\\
'''Meat Sweats:''' Well, actually, it's Rupert.\\
'''Splinter:''' ''(shudders)'' I would stick with Meat Sweats.
* EnergyAbsorption: His main ability as a mutant. He can absorb the energy and special abilities of any mutant (and presumably human) he touches if he can hold them long enough.
* EvenEvilHasStandards: He's somewhat taken aback by the news that Splinter stole from his own sons, [[SubvertedTrope although]] judging by his tone it could've just been [[DeadpanSnarker his idea of a humorous comment]].
** He is also shown to be concerned about crashing a civilian when Splinter speeds his vehicle.
* EvilChef: He's a villainous former celebrity chef whose gimmick is cooking and eating mutants.
* GluttonousPig: Probably purposefully invoked. Doesn't help that he's also a chef.
* IAmAHumanitarian: Does not have a problem eating other mutants or porkchops for that matter.
* IJustWantToBeNormal: Or returned to his old appearance, at least. He doesn't seem to mind the benefits his mutant form offers (increased strength and the ability to absorbs others' powers), but in ''Cloak and Swaggart'' he is quite distressed when he loses his human appearance once again. He also seems to miss being the host of his cooking show.
* KnowWhenToFoldEm: After having his truck damaged and being forced to release his mutant catches, he throws Splinter off, deciding that no meal is worth this.
* NoCelebritiesWereHarmed: Seems to be based on Gordon Ramsey.
* PowerCopying: He can absorb the life of other mutants, and steal their powers.
* SupremeChef: He was a celebrity chef as a human, and characters who've eaten his cooking rave about how delicious it tastes. His poisoned pizza puffs in their title episode practically fall under ImpossiblyDeliciousFood considering everyone who gets a taste keeps attempting to eat them, ''even after being told that they're poisoned''.
* VillainousGlutton: Doubles as a FatBastard.

->'''Voiced by: '''Creator/FredTatasciore''' (English), Oscar Garibay (Latin American Spanish)

A junkyard owner who was mutated into a mantis, he now makes a living repossessing and scrapping vehicles.
----
* EvenEvilHasLovedOnes: Even though he's a greedy, selfish jerk, he loves his pet cat, Mrs. Nubbins, even continuing to take care of her after she turns into a huge mutant and starts trying to eat his head.
* GreaserDelinquents: He dresses the part with a leather jacket and slick pompadour.
* {{Greed}}: His main character trait.
* HiddenDepths: He has a love for cats. He even keeps taking care of his cat after she mutates and starts wanting to eat him, despite how dangerous the task of just feeding her can be.
* JerkAss: While he [[EvenEvilHasLovedOnes loves his cat]], he's not a nice person, such as refusing to honor his part of Donnie and Mikey's deal despite them accomplishing their part in "Repo Mantis", and attempts to repossess an old woman's oxygen tank in "Evil League of Mutants".
* KickTheDog: His recruitment alongside the more overtly villainous Meat Sweats and Hypno-Potamus is prefaced by him trying to repossess the breathing tank of an old lady, showing that he can be just as dastardly as the other mutants Draxum conscripted.
* MoneyFetish: Gets very excited at the idea of a couple rich guys (Donnie and Mikey in disguise) buying his junk, to the point he almost sold his whole junkyard because they talked up their wealth so much.
* NoSympathy: He's a stereotypically merciless repo man. He once tried to repossess an old lady's oxygen tank.
* RidiculousRepossession: He tries to repossess an oxygen tank, and it was mentioned that he once repossessed a birthday cake.
* SecondaryColorNemesis: He's a villain with purple skin and green eyes.
* SlayingMantis: Not afraid to use his sickles.
* WingdingEyes: Has dollar signs for eyes at one point when he thinks Donnie and Mikey are a couple of rich customers who literally have cash to burn.

->'''Voiced by:''' John Michael Higgins (English), Roberto Molina (Latin American Spanish)

A newscaster who was mutated into a worm and lost his fame, he fancies himself as the turtle's greatest nemesis, but the Turtles (and almost everyone else) have no idea who he is.
----
* ADayInTheLimelight: His debut episode features him as the main character.
* AmbiguouslyGay: Is all but stated to be in a romantic relationship with Hypno-Potamus.
* BlessedWithSuck: His mutation gave him a stupidly slow HealingFactor while shrinking him down to the size of a worm.
* ComicallyMissingThePoint: When he witnessed a canon fire an air conditioner clean through a wall, he asked if it was safe for his HAIR to be fired out of the canon.
* DefeatMeansFriendship: Earned Hypno-Potamus' respect and friendship after defeating him in ''Newsworthy''.
* ExoticEyeDesigns: His take the form of two red, scribble-like rectangles in yellow sclera.
* FanDisservice: Good luck getting his buff form out of your head.
* IronButtMonkey: Every episode with him in it features him getting stepped on at the very least. He somehow always manages to shrug his injuries off.
* IrrationalHatred: He seemingly has no particular reason for considering the Turtles his arch-nemeses.
* KarmaHoudini: In the movie, after he and Hypno see the Foot Clan use the artifact they stole for them to unseal the SealedEvilInACan, they swiftly [[ScrewThisImOuttaHere bail]] with no repercussions shown.
* NonMammalianHair: Maintains his poofy blonde 'do from his human days.
* NotSoHarmlessVillain: Seems to be becoming this as of ''Stuck On You'', albeit still a huge ButtMonkey. [[spoiler:Unfortunately, he loses the gauntlet to Baron Draxum at the end of ''Warren & Hypno, Sitting in a Tree''. So he's back to being harmless.]]
* PintSizedPowerHouse: He's this while wearing the enchanted gauntlet [[spoiler:that is a part of Shredder's armor]], which gives him SuperStrength and the ability to fire devastating energy blasts.
* TheRightHandOfDoom: The disproportionately large gauntlet he wears, which gives him an equally disproportionately large and muscular arm.
* RunningGag
** He's literally an insignificant worm that almost everyone, including his self-proclaimed enemies, don't even know who he is or remember his name.
** He also gets bisected in some way fro pretty much every episode he appears in. Fortunately for him in the movie, only his hair gets cut in half, and its inexplicably fixed in the next scene.
* SmallNameBigEgo: Considers himself the turtles' greatest nemesis, but they barely even notice him, let alone remember him.
* TheOnlyOneAllowedToDefeatYou: He won't allow anyone else to destroy the Turtles but him, which is why he saves them from Hypno-Potamus in his debut episode.
* UnknownRival: Not only to the turtles, but as he considers himself their greatest nemesis, he clashes with other villains who target them. April is the only person who takes him seriously (as his number one fangirl).
* VillainousRescue: He saved the Turtles from Hypno-Potamus, because he believes [[TheOnlyOneAllowedToDefeatYou he deserves to defeat them]].

A magician formerly named Mezmer-ron who was mutated into a hippo by an oozequito bite. He has the ability to control his magic gimmicks with telekinesis and can hypnotize anyone (himself included) with ease.
----
* AffablyEvil: He's a polite and well-mannered villain towards the Turtles and rather friendly with his fellow villains, especially Warren.
* AmbiguouslyBi: His relationship with Warren is all but stated to be romantic, they even refer to their relationship as "complicated". He was also completely taken in by Mikey's female hippo disguise.
* AngryAngryHippos: A former stage magician turned massive humanoid hippopotamus and a talented criminal.
* BattleCry: Mezmer-ROO!
* CombatPragmatist: Some villains might take a hypnotized opponent and put them in a cell or death trap. Mezmer-Ron? Just as likely to cut the heads off his enemies while they're in an entranced state.
* EvenEvilHasLovedOnes:
** As a human, he was close to his pet hippo, Doug, and he wishes to resurrect him.
** Likewise, he genuinely cares for Warren, his best friend/roommate/[[AmbiguouslyGay it's complicated]].

!!The Foot Clan
[[folder:The Shredder]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shredder_1.png]]
[[caption-width-right:350:''"You are no match for The Shredder!"'']]
->'''Voiced by:''' Creator/HoonLee

The true leader of the Foot Clan. A set of cursed demonic armor brought to malevolent life, it's as powerful as it is vicious.
----
* ActorAllusion: He is voiced by Hoon Lee, the voice actor of Master Splinter in the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 series]], who in that show was ''also'' Karai's biological father [[ArchnemesisDad whom she swore to destroy]]... and she also swore to destroy The Shredder in that show too, making it a two-fold reference.
* AdaptationalAbomination: Downplayed. The Shredder in other incarnations is generally human, but in this series is a demonic set of armor that devoured the wearer and their soul.
* AdaptationalBadass: In other incarnations, Shredder is merely very proficient at combat, albeit usually at a greater skill level than the Turtles. This incarnation, however, is [[ExaggeratedTrope literally]] a [[AdaptationalAbomination destructive demon]] [[spoiler:that the Turtles have ''significant'' difficulty battling in their first real fight against him, [[ImplacableMan often because he just gets back up after a heavy hit]]]]. In most incarnations, Splinter alone is a worthy adversary to the Shredder, but in this case [[spoiler: not even Splinter and the Turtles ''together'' (along with April and Draxum), even empowered with mystic weapons this time, are capable of holding him back for more than a few minutes and find it nearly impossible to actually hurt him. He's shown being able to level buildings with the sheer air pressure of his blows alone, let alone when they connect.]]
* AdaptationalDumbass: While this series' incarnation is one of the [[AdaptationalBadass most powerful]] incarnations in the franchise, he noticeably tends to use very little strategy in favor of [[UnskilledButStrong completely overwhelming his opponents with brute strength]] in fights, whereas most incarnations of Shredder are well-practiced martial artists.
* AdaptationalHeroism: [[spoiler:Oroku Saki was actually a good man who only became the Shredder after making a deal with a demon so he could defend his village, and it's implied that this version is [[AndIMustScream trapped in his own body]], and leaves the heroes on peaceful terms after the Shredder is defeated.]]
* AdaptationalLateAppearance: Downplayed. In the comics and prior adaptations, the Shredder is generally introduced in the same story or episode the Turtles are. In this show, he's initially only hinted to exist and confirmed to be real in "Shadow of Evil", which takes place around the middle of Season 1, with the plot being about stopping his armor from being completed.
* AdaptationalNonsapience: Shredder acts like a raging animal with no intelligence, though the legends imply that he wasn't always this way. [[spoiler:He regains his sapience at the end of "E-Turtle Sunshine of the Spotless Mind"]].
* AdaptationalSympathy: [[spoiler:Oroku Saki's reasons for becoming the Shredder vary across continuities, but is generally an identity he adopts to become [[TheDreaded feared]]. In ''Rise'', Oroku Saki became Shredder out of a desperate attempt to protect his Clan, only for his soul to be devoured by the armor.]]
* AdaptationSpeciesChange: Shredder is almost always a human, but this version is a demon taking the appearance of a suit of armor.
* AncientEvil: He's been dormant for hundreds of years due to his armor being broken apart.
* AndIMustScream: [[spoiler:It's implied at the end of "Shreddy or Not" that the good man Oroku Saki still exists, but his will is buried under the evil armor, and is ultimately freed by the end of "Rise".]]
* AnimatedArmor: Is a demonic set of armor that gained life after consuming his wearer.
* ArchnemesisDad: In very technical terms. [[spoiler:The body he possessed and eventually consumed is that of Karai's father]].
* AttackAnimal: [[spoiler:Thanks to a mind control collar, he effectively became this to Big Mama, who restyled him as her Battle Nexus champion and main muscle. Then the Foot Recruit gets control of him in "Battle Nexus: New York"]].
* BadBoss: [[spoiler:In the series finale, once he reattains his sentience, he initially only shows [[MeanBoss mild annoyance]] at the antics of his three henchmen, but once Foot Lieutenant and Foot Brute get stuck under rubble, he tells Foot Recruit to abandon them.]]
* BigBad: [[spoiler:After spending much of the series as the GreaterScopeVillain, he steps into the role fulltime by the second season, but spends much of it as a mindless, raging brute. Upon regaining his sentience, he becomes the TrueFinalBoss of the series.]]
* CameBackWrong: [[spoiler:When he's fully brought back, he behaves more like a wild animal rather than someone you'd expect to be the leader of an evil ninja clan. Several characters make note of this, suspecting something went wrong during his resurrection. His physical form is also in flux, constantly phasing in and out of reality. It turns out to be due to missing his will, due to it being sealed away in another dimension. His sapience is restored in "E-Turtle Sunshine of the Spotless Mind" after his will is released from the Twilight Realm]].
* CastingAShadow: While under Big Mama's command, his Shadow Fiend-form is able to move through shadows and summon shadow arms to kidnap contestants for her Battle Nexus.
* ClippedWingAngel: [[spoiler:He's still plenty powerful when he's brought back, but his mind has apparently regressed to a feral beast, and he constantly phases in and out of reality, keeping him from delivering the finishing blow to the turtles time and again.]]
* CompositeCharacter: He's a demonic entity and resembles the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] Demon Shredder's original Tengu form, but the Foot Clan serves under him, much like traditional incarnations, which the Demon Shredder notably lacked beyond his Mystics (who were acquired by the Foot Clan the Utrom Shredder set up later in the timeline), and sports the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987]] Shredder's purple colors. His larger size also gives him a resemblance to [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze Super Shredder]]. The series finale also reveals [[spoiler:his armor was created by an alien being, giving him elements of Ch'rell.]]
* ContrastingSequelAntagonist: [[spoiler:Unlike Baron Draxum and Big Mama, both of whom had extensive resources, relied upon henchmen or allies, and were usually content to play the long game. The Shredder, by the final arc of the series, and the one where [[BigBad he takes center stage]], has very few henchmen to rely upon, is more likely to fight on the front lines, and is very proactive in getting to his plans.]]
* DealWithTheDevil: [[spoiler:He made a deal with a demon to transform him into the Shredder in order to defend the village. What he didn't know was that the process would corrupt his very soul.]]
* DramaPreservingHandicap: In his first appearance, [[spoiler: he's constantly phasing in and out of reality at random intervals, which is good news for the Turtles, since every encounter with him is an utter CurbStompBattle. The Shredder phasing out of reality in the middle of their first encounter was the only thing stopping him from slaughtering them all on the spot. [[FromBadToWorse Then he regains his sapience in "E-Turtle The Spotless Mind"]]]].
* TheDreaded: Just seeing the Foot Clan's sigil makes ''Splinter'' [[OOCIsSeriousBusiness get off of his butt]] to try to stop Shredder's armor from being completed. [[spoiler:As soon as the heroes realize that they've been fighting the Shredder in "Battle Nexus: New York", Splinter almost ''immediately'' commands everyone to retreat.]]
* EvilSoundsDeep: His roars and [[EvilLaugh chuckles]] have a noticeably bass-y reverb to them. [[spoiler:His actual speaking voice is actually slightly higher-pitched, but [[PowerEchoes still retains the reverb]]]].
* FallenHero: [[spoiler:Oroku Saki used to be a good man in this continuity until the armor corrupts him into what he is now.]]
* FlashStep: [[spoiler:He seems to have gained (or perhaps regained) the ability to do this some time before "Battle Nexus: New York"]].
* GreaterScopeVillain: He's the master of the Foot Clan, as well as an AncientEvil that even Master Splinter treats with the upmost seriousness, and stopping the Foot from reassembling his armor is a major plot point of the season.
* HateSink: [[spoiler:Upon regaining his sapience, the Shredder is firmly established to be a destructive murderer whose only concern is becoming invincible so he can continue his killing spree, he's [[BadBoss completely willing]] to throw away the lives of his henchmen (which significantly shakes the Foot Recruit's faith in him), and sees everyone as beneath him. Oroku Saki, however, [[AvertedTrope is not]] this trope, being an otherwise decent person who was pushed into a desperate situation, with the Shredder being a distinct entity.]]
* HopelessBossFight: The Turtles' first fight against him doesn't go very well in "Many Unhappy Returns", as despite the Shredder being effectively a wild animal, the gap between him and the Turtles is so large that the Turtles are forced to call in outside help to detain rather than outright defeat him. [[spoiler:Their rematches against him in "Battle Nexus: New York" and "Shreddy or Not" fare even worse, with the Turtles being forced to retreat in both, the latter one after he destroys all of their weapons. They don't make any significant progress in even ''hurting'' him until they unlock their Hamato Ninpo, and even then barely eke out a victory thanks to combining their powers and getting the help of the spirits of the Hamato Clan in "Rise".]]
* HumanoidAbomination: The Shredder has a humanoid shape, but is capable of inhumanly powerful feats such as [[spoiler:[[RazorWind cutting buildings]] with just the aftermath of swinging his arm, and shows some SizeShifting capabilities in the final battle, making him resemble a flaming EnergyBeing.]]
* ImplacableMan: [[spoiler:In "Many Unhappy Returns", no matter what the Turtles throw at him, they don't slow him down. It takes them discovering he's ticklish, can be blinded, and that he's attracted to sudden, bright flashes of light for them to gain any sort of advantage. When he returns in "Battle Nexus: New York", the combined efforts of ''eight'' fighters only serve to distract him slightly. It's only after getting cut in half by one large CombinationAttack from the entire Hamato Clan that he finally goes down for good]].
* InTheHood: [[spoiler:He wears a long hooded cloak while under Big Mama's control as the "Shadow Fiend"]].
* TheJuggernaut: This incarnation of Shredder is a powerhouse who raw power is unmatched and allows him to effortlessly overpower the turtles on several occasions. It takes ''everything'' and more for the heroes to finally defeat him in the finale.
* JumpScare: Any time ''anything'' related to his armor appears on screen in season 1, a sudden and brief flash of The Shredder's demonic face flashes on screen and gives a hoarse roar to indicate that Shredder is far more terrifying and dangerous than any other villain seen thus far. [[spoiler:Season 1 also closes on one that could very feasibly be Shredder ''actually roaring at the heroes''.]]
* KnightOfCerebus: The very first episode he's directly mentioned in is noticeably more serious, and rife with frightening, almost JumpScare level imagery showing the level of Shredder's atrocities, with even the villains being much more [[NoNonsenseNemesis direct]] than usual (barring a brief relapse from the Foot Lieutenant and Foot Brute). [[spoiler:His first real appearance in the series, while playing him a bit more for humor due to comedic weaknesses, shows him as a threat that is so outside of the Turtles' league that he very likely would have killed them if he wasn't [[DramaPreservingHandicap phasing in and out of reality]]. Once the Shredder's will is restored, he proceeds to cause the show's DarkestHour.]]
* MagicFromTechnology: A flashback in the second part of the season 2 finale strongly implies that [[spoiler: the Shredder's armour was created and given to Oroku Saki by an alien being (misinterpreted as a demonic oni) centuries ago, and is therefore advanced alien technology]].
* ManBitesMan: He tries to use his razor sharp teeth to attack his opponents at multiple points, he still does this even after he [[spoiler:regains his intelligence]].
* MechanicalAbomination: The series finale heavily implies [[spoiler:he's a suit of armor made from alien technology, and his [[ShapeshifterWeapon shapeshifting]] abilities heavily involve transforming his body into metallic tools or weapons.]]
* MythologyGag:
** This isn't the first time Shredder's been portrayed as a demonic entity, with the [[LegacyCharacter original]] in the 2003 incarnation being as such, and the armor in this incarnation looks very similar to that of the Tengu Shredder's original form. He also has other numerous stylistic similarities to the incarnations from that series, such as his glowing pink eyes that evoke the [[RedEyesTakeWarning red eyes]] from the 2003 version, the three-pronged crest on his helmet resembles that series' Foot Clan sigil, and his voice is edited to [[PowerEchoes reverberate]] like that series' bearers of the identity.
** Like in the [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 series']] Season 5 Kavaxas Arc, this version of the Shredder [[GeneticAbomination was turned into a monster]], then [[SealedEvilInASixPack separated into scattered pieces that was put back together]] by a cult-like remnant of the Foot Clan and a villainous ally that plans on using the revived Shredder for his own nefarious plot. Like in that arc, the Shredder CameBackWrong and ultimately led to the Foot Clan being destroyed once and for all.
** While the Shredder's signature steel claws are otherwise phased out of this continuity, [[spoiler:he briefly creates them a few times in the series finale in close range scuffles.]]
* NoNonsenseNemesis: [[spoiler:After regaining his sentience, he ''immediately'' decides to try and kill Karai in her weakened state due to her having defeated him before, and ignores anything that could distract him from becoming invincible. When the Turtles fight him to protect Karai, he destroys their mystic weapons to make fighting him much more difficult and almost kills every one of them, the Turtles only managing to escape due to the efforts of Karai, Splinter, and Draxum.]]
* NotHimself: [[spoiler:He behaves more like a rabid beast than an evil warlord when he's brought back to life. Multiple characters make note of how this behavior isn't in line with the legends. It's revealed to be a result of his will being sealed in the Twilight Realm, which is released at the end of "E-Turtle Sunshine of the Spotless Mind".]]
* PullingThemselvesTogether: No mortal weapon can pierce his armour, although some ''mystic'' weapons can. It's not much better though, since pieces of Shredder's armour that crack or break off almost instantly reconnect themselves.
* RazorWind: [[spoiler:When fought in "Battle Nexus: New York", he takes a swing at Draxum that he just barely dodges. The shockwave from said swing cuts all of the surrounding buildings in half.]]
* RealAfterAll: Splinter thought that the Shredder's legend was just a story.
* RelatedInTheAdaptation: [[spoiler:This version of Oroku Saki is a distant ancestor of Splinter/Hamato Yoshi and the Turtles, as the Hamato clan was founded by his daughter Karai.]]
* SealedEvilInASixPack: After his first defeat, the armor that contained his soul and power was scattered across the world (though a handful found their way into New York). He's then revived when the Foot manages to put them back together.
* SealedInsideAPersonShapedCan: Downplayed. [[spoiler:While his body can move, it lacks his will and is a wild animal. In "E-Turtle Sunshine of the Spotless Mind", once Karai is released, Shredder's will, sealed away in the Twilight Realm, returns to his body.]]
* ShapeshifterWeapon: [[spoiler:He can turn his body into a variety of tools or weapons, such as drills or his iconic steel claws.]]
* ShoutOut: [[spoiler:He turns into a large energy being resembling ''Anime/TengenToppaGurrenLagann'''s Granzeboma, and frequently turns his hands into drills.]]
* SmugSuper: [[spoiler:His true personality is a combination of this and an ArrogantKungFuGuy. He views everyone else, [[BadBoss even his own followers]], as completely beneath him, but considering just what it takes to put him down and his raw destructive power, he's got ''a lot'' to back up his mentality]].
* SpikesOfDoom: [[spoiler: After he gets his sanity back he displays the ability to summon a field of metallic spike from the ground as a means of taking out multiple opponents at once]].
* SuddenlyVoiced: [[spoiler:He finally speaks at the end of "E-Turtle Sunshine of the Spotless Mind", when he regains his sapience.]]
* UnskilledButStrong: [[spoiler:Whether he's a mindless animal or sapient, he shows very little finesse or strategic ability while fighting. This weakness is offset by his obscene strength (enough that he can cut buildings and destroy most of Big Mama's tower with just the ''air pressure'' of his blows) and durability, to the point ''eight'' people fighting against him in "Battle Nexus: New York", many of them being exceptional martial artists, are the ones at a disadvantage.]]
* VileVillainLaughableLackey: [[spoiler:Upon becoming sapient, most of the humor and levity comes from Foot Recruit, Foot Lieutenant, and Foot Brute's interactions with him, with the Shredder himself being a [[HateSink despicable]], no-nonsense monster.]]
* VillainousBreakdown: Implied. [[spoiler:After Casey betrays him and he loses his chance to consume Splinter's essence, his intent seems to shift to simply killing the Hamato Clan outright, to the point of turning into a [[OneWingedAngel much stronger form]] to overpower and demoralize them after they join their mystic powers together for one powerful attack. When the Hamato Clan regains the advantage through the help of the spirits of their ancestors, all he can do is shout the word "[[BigNo NO!]]"]]
* VocalDissonance: [[spoiler:When he regains the capacity for speech, his voice turns out to be fairly normal sounding despite it coming from a hulking, monstrous suit of armor]].
* TheVoiceless: [[spoiler: Coinciding with his mental regression into a mindless beast, he doesn't speak. All he does is roar, growl, and let out the occasional [[EvilLaugh evil chuckle]]. He finally speaks in the four part series finale.]]
* WasOnceAMan: [[spoiler:Oroku Saki was once a regular man until a demon corrupted his soul and transformed him into the Shredder.]]
* WeaksauceWeakness: [[spoiler:As it turns out, he's ticklish in the back of the knees. He's also left completely disoriented and open whenever he's blinded. Finally, he's single-mindedly attracted to and distracted by flashing bright lights. All three discovered weaknesses are used to successfully restrain him with Big Mama's collar. These weaknesses don't come up in any of his subsequent fights, however.]]

[[folder:The Foot Clan]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/riseoftmntfoot.jpg]]
->'''Foot Brute Voiced by:''' Creator/MauriceLaMarche (English), David Allende (Latin American Spanish)\\
'''Foot Lieutenant Voiced by:''' Creator/RobPaulsen (English), Daniel Lacy (Latin American Spanish)\\

The Foot Clan are a group of evil ninjas bent on taking over New York City! They have the power of teleportation through hidden gateways and the ability to create and control Origami Ninjas.

The known members include a short man credited as "Lieutenant", a large man credited as "Brute", and later on a female recruit (who has a separate entry).
----
* AncientArtifact: They spend the first season scouring New York for powerful artifacts, including a power gauntlet. It's eventually revealed that the artifacts in question are pieces of ''[[ArchEnemy the Shredder's]] armor''.
* AdaptationDeviation: While previous incarnations of the Foot Clan had dabbled with magic, this one is much more heavily tied to the supernatural, and are essentially a cult devoted to the Shredder.
* AmbiguouslyHuman: Despite the Foot Clan usually being human, the both the Lieutenant and the Brute are extremely odd looking, having purple skin and creepy facial features. Both Lieutenant and Brute have question marks on the human entry of their official bios. It doesn't help that their master, The Shredder, is a demonic set of AnimatedArmor in this continuity.
* ArchEnemy: Although things are different in this continuity, the Foot Clan as a whole remain this to the Hamato Clan, the Turtles especially, by being their most recurring foes and involved in many major events like the return of The Shredder and the Krang invasion. They even team up with Baron Draxum under the mutual assurance they'll defeat the Turtles together.
* BaldOfEvil: Not a hair on either of their evil heads.
* BigBadWannabe: They're responsible for most of the major conflicts of the series, from [[spoiler:manipulating Draxum into releasing the Shredder and later personally freeing the Krang, but tend to find themselves on the receiving end of EvilIsNotAToy in these plots]].
* BodyHorror: [[spoiler:The Krang mutate them into monsters to turn them into stronger minions.]]
* BrainsAndBrawn: The Lieutenant is the brain to the Brute's brawn.
* BullyingADragon: [[spoiler: While they were in their rights following the rules of the organization, treating Baron Draxum in a demeaning manner as opposed to an equal partner was a big mistake on their part, especially after he used those same rules to usurp control of the Foot Clan from them. They do get one over Draxum in the end though, manipulating him into resurrecting the Shredder for them.]]
* {{Cult}}: The group worships and makes a goal of resurrecting the Shredder. ''The Movie'' reveals that the group also worship the Krang.
* CompositeCharacter: The organization appears to take after different versions of the Foot Clan across different incarnations; they're a ninja group as per usual, but the AmbiguouslyHuman nature of the main enforcers and cult-like nature are respectively similar to the Foot Mystics from the 2003 cartoon, and the Foot cult from Season 5 of the 2012 cartoon, with the same goal as both; resurrection of the Shredder.
* CoDragons: For the Shredder. The Lieutenant and Brute appear to be of equal standing with their only authority being over the Recruit and the Origami Ninjas. They later become Baron Draxum's when he usurps control of the clan.
* DragonWithAnAgenda: Despite Draxum forcing them to yield to his authority, they still plan to bring back the Shredder and successfully manipulate him into putting the armor on, reviving their master.
* EarlyInstallmentWeirdness: The Foot Lieutenant and Foot Brute's ability to create Origami Foot Soldiers is largely dropped midway through Season 1 in favor of flesh-and-blood soldiers, and they never do it in Season 2 (albeit largely due to [[OutOfFocus not showing up]] until the final episodes).
* EvilDuo: They're always causing trouble together.
* EvilIsPetty: In "Mystic Library", once they see the Turtles are at the titular location, decide to interfere with whatever they're doing for no other reason except revenge for frequently being defeated.
* EvilSoundsRaspy: The Foot Lieutenant speaks in a raspy whisper that sounds like the result of a lifetime gargling sharp pebbles.
* EyesAlwaysShut: The Brute has eyes, they're just not visible most of the time.
* FatAndSkinny: The Foot Brute is built like a monster truck, and is at least four times wider than the Lieutenant.
* GlassCannon: The Origami soldiers are strong enough to knock Raph clear across the room, but are about as durable as you'd expect for beings made out of paper.
* TheHeavy: [[spoiler:With the Shredder gone, the Foot Clan spend much of Season 1 moving heaven and earth to resurrect him.]]
* {{Irony}}:
** They are big fans of Lou Jitsu but they are unaware that he's actually the last living descendant of [[spoiler:their ancient enemies, the Hamato clan]].
** [[spoiler:The Foot Clan's descent into evil was inadvertently caused by Oroku Saki trying to prevent it from being wiped out. Now the Foot Clan is effectively a cult that worships the Shredder, who will wipe out humanity if left unchecked.]]
* HiddenAgendaVillain: They're looking for artifacts for an unspecified reason. "The Longest Fight" ends with them stealing some sort of sharp gauntlet (with the Turtles thinking they just tried to steal what they call a "puny ring"), and they attempt to steal a similar gauntlet in "Stuck on You". "Shadow of Evil" sets the record straight, revealing that they're acquiring pieces of the Shredder's armor to resurrect him.
* LogicalWeakness: Their Origami soldiers are naturally pretty fragile, and water easily destroys them, and also renders them unable to create more.
* ManipulativeBastard: [[spoiler:They offer Draxum the Shredder armor in exchange for his assistance in tracking down the pieces, conveniently omitting the fact that the armor would drain his life force to reanimate itself.]]
* MookMaker: The Lieutenant is adept at origami, which allows him to deploy several Soldiers at once.
* NoNameGiven: They're credited as the "Foot Lieutenant" and "Foot Brute", with no hint to their real names given.
* NotSoAboveItAll: The Lieutenant and Brute are fans of the Lou Jitsu movies, with the former, generally the smarter and more serious of the two, gushing about the films in "Hot Soup: The Game" alongside the Brute. "End Game" shows this extends to them being so awed by [[spoiler: Splinter, a transformed Lou Jitsu, clobbering their minions that they forget to dodge his attack.]]
* NotSoHarmlessVillain: They often banter with one another, frequently engage [[VillainsOutShopping in various mundane activities]] and will gush about Lou Jitsu but they are also fairly competent fighters in their own right and they successfully [[spoiler:manipulate Draxum into wearing the life draining Shredder armor so as to resurrect their demonic master]].
* PaperMaster: They can bring their Origami soldiers to life as this series' incarnation of the Foot Soldiers.
* PowerTattoo: They have an orange foot tattoo on their faces that appear to emit flames. It's apparently part of being elevated to full clan status and is received via getting ''kicked in the face'' by a high-ranking member of the clan.
* TheRival: The Foot Brute acts as this to Raphael in their battles and in the opening.
* ShooOutTheClowns: [[spoiler:Shredder leaves the Foot Lieutenant and Foot Brute for dead under rubble in the series finale, which both sidelines the humor in favor of focusing on the urgency of defeating the Shredder, and instigates the Foot Recruit's HeelFaceTurn.]]
* WhatHappenedToTheMouse: [[spoiler:Whether the Foot Clan members were reverted to being human or [[AmbiguouslyHuman whatever Lieutenant and Brute are]] after the events of TheMovie isn't made clear.]]
* ZergRush: Their Origami Soldiers aren't very tough, but make up for it with sheer abundance.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tumblr_pn0ygx69nk1xh4d0to6_1280.png]]
->'''Voiced by:''' Creator/ZeldaWilliams (English), Pamela Cruz (Latin American Spanish)

A young woman who very desperately wants to become a full member of the Foot.
----
* AdaptationalVillainy: [[spoiler:Unlike previous iterations of Casey Jones, who's an ally of the Turtles from the start, this version is a fanatic follower of the Foot Clan and a recurring villain up until her HeelFaceTurn in the finale.]]
* BadassNormal: Usually fights unarmed against the superhumanly strong heroes, and without access to the supernatural powers of her senior officers.
* BloodKnight: The Recruit's predilection towards violence is so intense that the Lieutenant and Brute actually [[EvenEvilHasStandards show some concern towards her]].
* BoyishShortHair: Her hair is cut very short, and there's very little that's feminine about her.
* CanonCharacterAllAlong: [[spoiler: "Rise" reveals that she's indeed this show's version of Casey Jones. The ''present day'' version, to be more specific.]]
* ChildProdigy: She was apparently accepted into every clan she applied to as a child.
* ChildSoldier: She's apparently been training with the Foot since she was seven.
* TheComicallySerious: She reacts to every situation with the same bombastic intensity she always has, even if she's just doing something mundane like going on a coffee run for her bosses.
* CompositeCharacter: You would be forgiven in thinking that she was this series' version of Karai, being a DarkActionGirl that runs the Foot Clan when the Shredder isn't and has a love/hate relationship with the turtles, but the series finale reveals [[spoiler:that she's actually one of this series' incarnations of Casey Jones.]]
* DarkActionGirl: The Recruit is just as deadly as her two superiors, being just as capable of keeping up with the Turtles. [[spoiler:She becomes a more straightforward one after her HeelFaceTurn]].
* DecompositeCharacter: She's basically all of Karai's more villainous attributes (a ruthless Foot Clan kunoichi with a love/hate relationship with the turtles) rolled into a separate character [[spoiler:despite being the show's first version of Casey Jones]], this show's version of Karai being [[AdaptationalHeroism a total force for good]].
* TheDragon: Despite being lower on the totem pole than the Lieutenant and Brute, she winds up becoming the Shredder's in the finale, before undergoing a HeelFaceTurn.
* DudeWheresMyRespect: She expresses frustration when a group of Foot initiates are promoted to full membership while she gets passed over, despite her being there longer than any of them.
* EvenEvilHasStandards: [[spoiler:She's completely unnerved by the Shredder's command to just abandon the Foot Brute and Foot Lieutenant in the rubble, which contributes to her HeelFaceTurn.]]
* EvilCounterpart:
** Similar to April in how she's a passionate tertiary member of a group of ninjas... Except evil. Splinter himself compares the two in "Always Be Brownies", albeit without explicitly naming April.
** She's also positioned as one to Mikey in her debut episode. Both are sensitive to criticism and hopeful to prove themselves to their teammates... but she lashes out ''far'' more intensely than Mikey.
* EvilGloating: Has a bad habit of standing still and laughing at her enemies [[ArrogantKungFuGuy whenever she's winning in a fight]], which just allows her opponents to turn the tables on her.
* {{Foreshadowing}}: Toward her [[CanonCharacterAllAlong true identity]]:
** In "Always Be Brownies", the Girl Scout organization she runs is called "Grandma CJ", and there's sports equipment in her room, [[spoiler:which hints that she's actually '''C'''asey '''J'''ones.]]
** In "Battle Nexus: New York", she fights [[EnemyMine alongside]] the Turtles against the Shadowfiend, prominently using April's baseball bat which she threw to her. [[spoiler:Baseball bats are one of Casey Jones' staple weapons, and the fact she fights with the Turtles is hinting at [[HeelFaceTurn her redemption]].]]
* GenderFlip: [[spoiler:Downplayed. There are two Casey Jones incarnations: she's the show's present day incarnation, while a son of hers resides in the BadFuture.]]
* GirlScoutsAreEvil: In "Always be Brownies", she [[OffscreenMomentOfAwesome somehow]] ends up founding and running an organization analogous to the Girl Scouts with the intention of taking over the world through bake sales. The members of her organization, who are preteen girls at most, are all trained in ninjutsu, including bladed weapons.
* GivenNameReveal: In "Rise", she [[spoiler:quits the Foot Clan]] and reveals her name [[WhamLine in a rather dramatic fashion]]:
-->"The name's [[spoiler:Cassandra, ''[[CanonCharacterAllAlong Cassandra Jones]]''!]]"
* HeelFaceTurn: [[spoiler:After seeing the full extent of Shredder's cruelty, Foot Recruit decides to turn on him and join the good guys.]]
* HeroOfAnotherStory: At the end of TheMovie she texts April a series of selfies that show her fighting the Krang invasion on her own.
* HiddenDepths: "Always Be Brownies" has her running a successful Girl Scouts-esque organization, with the end of the episode suggesting that she also engages in sports, due to sports equipment being able to be spotted in her room. [[spoiler:The latter turns out to be [[{{Foreshadowing}} a hint]] that she's really [[OneSteveLimit (a)]] Casey Jones.]]
* {{Irony}}: She angrily tells Big Mama in "Battle Nexus: New York" [[spoiler:that she enslaved her master, the Shredder. However, Shredder was so insane, she had to ''keep'' him under the same control to serve him in the long term.]]
* LargeHam: She spends a lot of her screentime gesturing dramatically while shouting.
-->'''The Recruit:''' (as she jumps off a building) '''"FOOT CLAAAAN!"'''
* NoIndoorVoice: There's rarely a moment where she isn't shouting.
* NoNameGiven: Is simply credited as "The Foot Recruit" in and out of universe, and eventually even that's shortened down. [[spoiler:It's revealed that her name is [[CanonCharacterAllAlong Casey Jones]]]].
* NotSoAboveItAll: Just like her bosses, the Recruit isn't above goofy behavior. During her fight with Raphael during "Insane in the Mama Train" she even gets locked in a prolonged "bring it on"-off and knocks his hand off course so he uses the train's transport system to jump to the wrong room with a mischievous smirk.
* NotSoHarmlessVillain: [[spoiler:Becomes a lot less funny and a lot more threatening once she gets control of the Shredder.]]
-->''I'd run, if I were you.''
* OOCIsSeriousBusiness:
** [[spoiler:In "Battle Nexus: New York", she talks ''much'' more quietly to Big Mama after taking control of the Shredder and preventing her escape.]]
** [[spoiler:After Shredder abandons his Lieutenant and Brute, she's so shaken by it that she doesn't [[LargeHam speak bombastically]], even when trying to deny that she's having second thoughts about being the Shredder's General. She only starts acting more like herself after [[HeelFaceTurn saving Splinter's life]].]]
* SuddenlyShouting: She has a tendency to start speaking normally before abruptly yelling at the top of her lungs
-->'''The Recruit:''' I shall return. '''STAY HERE AND DO NOTHING!'''
* TomboyishName: [[spoiler:She shares the same first name as her male counterpart, though in this case, it's short for "Cassandra"]].
* UndyingLoyalty: The Recruit is fanatically loyal to the Lieutenant and Brute, blindly obeying any order they give her, until she clashes with them over controlling Shedder when she wants to set him free. [[spoiler:She ultimately turns on the Foot after witnessing The Shredder's cruelty even to them.]]

[[folder:The Krang ('''UNMARKED SPOILERS''')]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/kraanggg.png]]
[[caption-width-right:350:From left to right: Krang Three, Krang One, Krang Two]]
->'''Voiced by:''' Creator/JimPirri (Krang One), Creator/ToksOlagundoye (Krang Two)

Creatures that the Foot Clan worshipped who turn out to be alien invaders. The main villains of ''WesternAnimation/RiseOfTheTeenageMutantNinjaTurtlesTheMovie''.
----
* AdaptationalAbomination: Krang is typically depicted as an alien invader with no greater abilities beyond more advanced technology. In ''Rise'', however, the Krang are able to spread bio-mass that can infect people and convert them into more Krang, can nullify the Turtles' mystic powers, and are so beyond the Turtles' abilities that Krang One is able to counter one of their strongest attacks with just the air pressure from a flick.
* AdaptationalBadass: Whenever the Krang have been depicted as a species in previous continuities, they were pretty much dependent on their technology to make them anything resembling a threat. The Krang here are positively ''vicious'' even in their base form, delivering a CurbStompBattle to the Turtles when they first reemerge, with Krang One in particular being an ''outright'' InvincibleVillain and remains undefeated through the entire movie's runtime, the Turtles resorting to having to stall him to make sure the invasion fails.
* AdaptationalLateAppearance: Krang in prior incarnations showed up in the second episode of the 1987 cartoon, and is established from the get-go to be one of the primary antagonists of the 2012 cartoon. In ''Rise'', the Krang formally appear in the movie, which takes place after the end of the second season, though the group are also heavily hinted to exist in said season.
* AdaptationalSeriousness: Prior incarnations of Krang are generally humorous, with even the 2012 character (who was reimagined as an emotionless hive mind) demonstrating a number of comedic beats. The Krang in this incarnation have far less comedic personalities, and are rarely played for jokes beyond a comment about Krang Two's [[FlatCharacter shallow characterization]] and some slapstick (such as Krang Two getting a book thrown in her face).
* AdaptationalUgliness: Krang's exosuits across incarnations tend to look and be very humanoid, with varying degrees of mechanical complexity. The Krang's exosuits in ''Rise'', however, look far more monstrous and organic.
* AlwaysChaoticEvil: We only experience four Krang in the show; one dead and three alive. The alive examples immediately start [[BodyHorror turning people into mindless beasts and biomass]] with the intent of doing it to the rest of the planet with the Technodrome. The dead example turned the kind and compassionate Oroku Saki into a monster hell-bent on enslaving humanity.
* AmbiguousSituation: It's heavily implied that the reason there are only three Krang left is because the surviving three killed the rest after their prior invasion failed, but this is never outright confirmed in the film itself.
* AntiMagic: Just by ''screaming at them'', Krang One manages to completely nullify the Turtle's mystic powers.
* ArchEnemy: Krang One becomes this to Leo. Since Krang One was the one who turned Raphael into a monster like the rest of the Foot Clan and Leo was responsible for sending him back to the prison dimension as well as ruining all his plans, the hate the two have for each other is mutual.
* TheAssimilator: They conquer worlds by spreading MeatMoss over them, which twists organic life and technology alike into weapons under their control. There were presumably many of their species that could do this, but among the present three, only Krang Three is explicitly shown making use of this ability.
* AsskickingLeadsToLeadership: Krang One speaks on the behalf of his species and is practically unstoppable in every one of his combat encounters. He doesn't even get handed a physical defeat. The best the Turtles could do was strand him in a separate dimension.
* AxCrazy: Krang Two is the most notable regarding this trait, with almost everything she says being about how she wants to kill something, though Krang One also showcases it, murdering the crews of two helicopters (one being a police chopper and the other a Channel 6 News chopper) despite neither posing much of a threat to him.
* BadBoss: Krang Three assimilates the Foot Clan into their ranks right after Foot Lieutenant says that they'll be right behind the Krang in their efforts, the process of which looks very [[PainfulTransformation painful]].
-->'''Foot Lieutenant:''' We live to serve.\\
'''Krang One:''' You will serve me, whether you live or ''not''.
* TheBadGuyWins: As future Leonardo lampshades it, the Krang practically won in the BadFuture where they take over the Earth and it's up to Casey to undo it by going back in time and prevent their invasion from happening in the first place.
* BigBad: Krang One is the leader of the trio in their plans to conquer earth and subsequently the main threat of the movie.
* ClippedWingAngel: Splinter and Casey actually have an easier time fighting Krang Two in her suit than outside of it, as Krang Two ends up losing access to her CombatTentacles while wearing it.
* CoDragons: Due to Krang One primarily taking upon a commander role, Krangs Two and Three share the role of his main subordinate, with Three evidently being the only one capable of spreading their assimilating biomass while Krang Two takes the role of "field" enforcer.
* CompositeCharacter: Like the 2012 series, the Krang are a group of alien invaders who seek to turn the entire universe into an extension of themselves, with the size of them and their exosuits taken from that series' Kraang Prime, but the spelling of their name and straightforward dialogue are [[TruerToTheText closer to]] the 1987 cartoon incarnation of the character, with their more serious characterization being similar to the 2003 series' Ch'rell, an evil Utrom who was very similar to Krang, with their exosuits bearing some resemblance to the [[RedAndBlackAndEvilAllOver black and red]] Utrominators and the exosuit used by the Shredder in "Same As It Never Was".
* ContrastingSequelAntagonist: While the Krang are heavily implied to have [[GreaterScopeVillain created]] the Shredder and possibly the mystic underbelly of the whole planet, they're still very different in that they're full-on alien invaders in a series where almost every primary and secondary villain have been mystical. The Krang are also much more direct in their evil plans, not even bothering with going incognito like prior villains did, managing to conquer New York within ''hours'' just from overpowering their opposition.
* DarkActionGirl: Krang Two is positively giddy in her rampant bloodlust and desire to kill her opponents.
* DecompositeCharacter: The Krang are the name of an alien species in this incarnation, similar to the 2012 series, but the film has only three of them (due to the rest having died in imprisonment), making the result be Krang is split into multiple characters; Krang One being the central commander, Krang Two being the one who goes out to enforce his will, and Krang Three either adding more to their ranks via assimiliation or operating the Technodrome.
* TheDreaded: The Krang are such a dangerous threat that after the future Leonardo has concluded that the resistance have failed and he, Mikey, and Casey have no chance of winning against them, he asks Mikey to send Casey back in time to try and stop the invaders from arriving ''at all''. In the present, the Turtles do not believe Casey's claims of being from the future until he mentions the Krang, whom Splinter has heard of and takes the idea of their invasion seriously.
* EldritchAbomination: Possibly the straightest the Krang have ever played this. Their technology is completely organic and formed from their own biology, and they're driven to assimilate every planet they land on.
* EvilCounterpart: The Krang in general (and Krang One in particular) are a narrative parallel and contrast to Leo himself, in that both (mistakenly) view true strength as coming from one's singular capabilities. The main difference is that, while Leo's view of strength in this manner comes as a result of his [[InferioritySuperiorityComplex inferiority complex]] and constant need to prove himself to his family (and his character arc in the film is about him overcoming this mindset), the Krang's view of strength stems from their belief that [[TheSocialDarwinist they are already inherently superior to everyone else]].
* EyesDoNotBelongThere: Matter that the Krang assimilate have a tendency to grow eyes everywhere, which is somewhat ironic considering the Krang themselves only possess two eyes.
* FatalFlaw: Krang One's is {{Pride}}. He looks at all other species as beneath him, causing him to make dangerous errors in judgment due to underestimating creatures he perceives as weaker than the Krang, both in the past and eventually millennia later, which results in both invasions ending in failure thanks to the Hamato Clan.
* FateWorseThanDeath: Krang One gets trapped back in the prison dimension alone (with Krang Two being trapped on Earth and Krang Three likely dead due to the Technodrome's destruction), possibly forever.
* FinalBoss: The Krang serve as the final threats that the Turtles must contend with, with Krang One being the last enemy the four face together.
* FlatCharacter: Krang Two is defined by her AxCrazy nature, with almost all of her dialogue being about how she wants to kill something. Splinter ends up [[LampshadeHanging complaining]] about her lack of depth when having to fight her.
* GreaterScopeVillain: The Foot Clan worships them, and it's heavily implied that the Foot Clan's champion, the Shredder, was created with their technology.
* HeroKiller: They manage to vaporize future Leonardo shortly after he sends Casey to the past and Krang One is dangerously close to finishing off the present one when the two are locked in the prison dimension. However, Leo's brothers are able to rescue him just in time and his death is undone.
* InvincibleVillain: Krang One far outclasses ''anything'' the Turtles can throw at him, especially after he dons his PowerArmor. The best they can do is strand him back to his prison dimension.
* KnightOfCerebus: After the Krang appear on Earth, the tone noticeably becomes much darker due to the Krang being stronger than everything the Turtles have fought before, even the Shredder, with the film almost going in a much more horror-oriented direction. They also prove to be the ''only'' enemy that the Turtles can't beat in a straight fight, which forces them to just make sure the invasion fails [[WeWinBecauseYouDidnt instead of defeat them outright]].
* LackOfEmpathy: Krang One doesn't feel sad for the near extinction of his race under the belief that they wouldn't have died [[TheSocialDarwinist if they weren't weak]], and can't understand why the Turtles protect the human race despite being stronger than them.
* LovecraftianSuperpower: They are able to generate a grotesque MeatMoss from their bodies and mutate other living beings into [[TechnicallyLivingZombie horrifying monstrosities that obey their every whims, which in turn can do the same to anyone uninfected that they could get their claws on]]. The biomass they generate are also [[OrganicTechnology what makes up a majority of their technology]].
* MadeOfIron: Their bodies are apparently incredibly resistant to even bladed weapons, which they react to as though they were being hit with blunt objects. Krang Two notably doesn't die when April crushes her with a wrecking ball and continues to flail about while trapped under it. The only thing that seems to do permanent damage to them is experimental herbicide that April stole from a lab, and possibly the explosion created from the Technodrome's destruction, [[UncertainDoom considering Krang Three disappears after that point]].
* MightMakesRight: Krang One espouses that it is TheRightOfASuperiorSpecies to conquer the universe and subjugate all other life, and since he sees the Krang as that SuperiorSpecies, it is therefor within his rights to terraform the Earth.
* MythologyGag: Each incarnation resembles a prior incarnation of Krang or a character similar to him:
** Krang One's rectangular shape is reminiscent of the 2003 series' Ch'rell, and has sharp looking "eyebrows".
** Krang Two [[EyeScream loses her eye]] in a fight with April, which is likely a reference to the prior series' Kraang Sub-Prime, that series' [[TheDragon second-in-command]] of Kraang Prime, having a cybernetic eyepatch (though Krang Two loses her right eye while Sub-Prime lacks his left).
** Krang Three resembles the 1987 incarnation of the original Krang, being smaller and more brain-like than his more octopus styled siblings.
* NeverHeardThatOneBefore: Krang One is amused when Raphael says that it's his duty to protect the human race, because other races they've fought and consumed spoke of it as well.
-->'''Krang One:''' "Hm. You're more powerful than the people of this planet, yet, you defend them... Why?"\\
'''Raphael:''' "It's my duty."\\
'''Krang One:''' ''(chuckles)'' "A word used by the weak. Many planets before yours have spoken of 'duty'; they too have been consumed by the Krang."
* NoNameGiven: The Krang are not given separate official designations, and the credits just label them numerically in order of appearance. The most we get is Krang One referring to Two and Three as "sister" and "brother" respectively.
* NonStandardCharacterDesign: Krang One stands out among other depictions of Krang/Utroms, even compared to his siblings. He looks almost nothing like a brain, being much taller and rectangular in shape. He's also purple as opposed to pink.
* NotSoWellIntentionedExtremist: Krang One boasts that he and his siblings are out to restore the natural order of things, that [[TheSocialDarwinist the strong devour the weak]], and that he's "saving" the Earth. No one ever buys it, especially since it's shown that the future of Earth is a hellish landscape littered with dead bodies that weren't even assimilated.
* OutsideContextProblem: The Krang are alien invaders in a series where a majority of the RoguesGallery have magical powers, and with very few ways to effectively counter them beyond sealing them in another dimension or chemicals April found at Eastlaird University. They're also capable of outright ''disabling'' the Turtles' mystic powers, something that was largely only possible in the series when they lost their weapons.
* OrganicTechnology: To Donnie's disgust, their technology is created from them attaching their biomass to objects and then puppeting them around.
* OriginalPositionFallacy: Krang One believes that [[TheSocialDarwinist the weak exist to be devoured by the strong]]. Raphael manages to get under Krang One's skin by pointing out that he and his race were trapped in another dimension for millennia by people who they considered much weaker than them; Krang One's only defense is that it was a "rare misstep".
* PowerArmor: They don a particularly intimidating set after summoning the Technodrome, with Krang One in particular becoming a full-blown InvincibleVillain while wearing it.
* PowerNullifier: Krang One at the very least possesses the ability to seal away the Turtles' mystic powers, though the Turtles in the end manage to overcome this through sheer HeroicWillpower.
* {{Sadist}}: Krang One clearly enjoys pitting a brainwashed Raphael against Leonardo and watching Leo suffer fighting his own brother. Krang Two also seems to have this trait, given that while she prefers [[AxCrazy simply killing her enemies]], once Leonardo seemingly ends up lost to the prison dimension alongside Krang One, she laughs at the grieving April and Splinter.
* SealedEvilInAnotherWorld: They were locked away in a separate dimension a thousand years ago when they first attempted to invade Earth. Krang One ends up getting sealed back in that dimension, as he proves to be too physically powerful to actually defeat.
* TheSocialDarwinist: Krang One isn't broken up about him and his siblings being the only ones left of their kind, feeling that the rest of his kind simply weren't strong enough to survive the thousand years trapped in another dimension. He also declares that their invasion is justified because 'the strong consume the weak'. While not stated outright, it's implied that after the Krang were all banished to the other dimension, the Krang all turned on each other in a fight for dominance, the three Krangs we see in the movie the only ones who survived.
* SoreLoser: After the Turtles manage to upend their invasion, Krang One, trapped in the prison dimension alongside Leonardo, angrily decides to kill Leonardo for destroying the Technodrome and ruining his plans, becoming even more angry when Leo smiles at the fact he saved his family and the world.
* TouchTelepathy: When Raphael refuses to give away the location of their lair, Krang One decides to read his mind by placing his tentacles on his head (and possibly ''[[BodyHorror under Raph's skin]]'').
* ToylessToylineCharacter: The accompanying toyline for the show had ended prior to TheMovie, making the Krang among the few major villains in the series to not get an accompanying toy.
* TruerToTheText: While the invaders share the same name and modus operandi of the prior 2012 animated incarnation, the Kraang, their name is spelt like the original 1987 incarnation, and at least two of the Krang speak in a very human manner like the 1987 Krang, unlike the overly formal and often [[DepartmentOfRedundancyDepartment redundant]] manner from the 2012 series Kraang.
* WalkingSpoiler: Considering the fact that they're the ones the Foot Clan worships and are heavily implied to be the ones indirectly responsible for creating The Shredder, they can be nothing but this.
* UncertainDoom: Krang Three is last seen being swatted away by Donatello after Donatello gains control of the Technodrome. Considering the Technodrome explodes afterwards, it's possible that he was killed in the blast.
* VillainousBreakdown: Krang One starts to lose his composure after Raphael starts to resist his brainwashing, becoming irritated and starting to actively take part in the fight through trying to assimilate the three other brothers. After he and Leo are stranded in the prison dimension and the Technodrome is destroyed, Krang One quickly loses his temper and starts beating down on Leonardo, and becomes more incensed when Leo smiles after having resigned himself to being trapped there as long as his family is safe. His breakdown is complete when Leo's brothers save him from the prison dimension but keep Krang One trapped inside of it, being unable to do anything except scream in anger at his fate.
-->'''Krang One:''' ''Wipe that grin off your face!''
* VirtueIsWeakness: Krang One mocks Raphael when he espouses his sense of honor and loyalty [[NeverHeardThatOneBefore since every other species he's wiped out made similar claims]].
* TheVoiceless: Krang Three does not speak a word in any of his appearances, save for once, when he speaks through his MeatMoss thralls.
-->'''Krang Three:''' Yes, brother.

!!The Hidden City
[[folder:Big Mama]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/bigmama_profile_render.png]]
[[caption-width-right:350:[[labelnote:Her human disguise]]https://static.tvtropes.org/pmwiki/pub/images/bigmama_human_form_pic_4.png[[/labelnote]]]]
->'''Voiced by:''' Creator/LenaHeadey (English), Rocío Garcel (Latin American Spanish)

A shapeshifting spider youkai who runs the Grand Nexus Hotel, which operates as a hotel for humans and a hub of activity for youkai. Beneath her cheery exterior lies a rather ruthless crime boss who's always looking to expand viewership for the Battle Nexus, a popular gladiatorial arena in the Hidden City.
----
* AbhorrentAdmirer: Subverted. Even after the revelation that she's giant spider youkai, Splinter still has feelings for her. It helps that he becomes non-human.
* AffablyEvil: She seems to have some real fondness for the mutants working under her, but she runs the Battle Nexus, which is essentially blood sport. Her compliments toward Donatello's technology also seem to be, to some extent, genuine, even if it's obviously playing to his ego.
* AFormYouAreComfortableWith: She's capable of shape-shifting from her spider form into a more human-looking form, albeit a purple human.
* AmazingTechnicolorPopulation: Her human disguise has purple skin and white hair.
* BigBadEnsemble: By the end of "Bug Busters", she's become another major antagonist on equal footing with Baron Draxum (and later the Foot Clan when they ally with Draxum) due to using his Oozesquitoes to create more mutants to participate in the Battle Nexus. [[spoiler:At least that was the case until season two, where Baron Draxum undergoes a HeelFaceTurn and she's kicked out of the BigBad role by the Foot Clan once they regain control of Shredder.]].
* BigBadWannabe: [[spoiler:Season 2 has her appear discretely at the end of multiple episodes to steal away prior villains, setting up her grand reveal in "Battle Nexus: New York" to turn New York into her new Battle Nexus arena. However, her plan hinges largely on her control over [[DragonInChief The Shredder]] as her personal enforcer, so when she loses control over him to the Foot Recruit, she's quickly upstaged while he proceeds to regain his sentience and become the final villain of the series]].
* BrightIsNotGood: The true appearance of her hotel is full of bright implements with a fairly comfortable atmosphere, and Big Mama herself has a human disguise with an emphasis on very light colors. The hotel is also home to a blood sport, and Big Mama herself is one of the series' main antagonists.
* ChronicBackstabbingDisorder: Unless it's in her best interests to [[PragmaticVillainy play nice]], she will most likely betray the other party: she takes the Oozesquitoes from the Turtles in "Bug Busters" (which she provided the resources to capture) to make more Battle Nexus contestants, and her backstory involves [[spoiler:buddying up with Lou Jitsu only to kidnap him and force him to partake in the Battle Nexus (though her feelings were genuine)]]. In "Many Unhappy Returns", [[spoiler:Leonardo actually [[ExploitedTrope exploits]] her untrustworthy nature; he escalates the deal to help them in exchange for a fight in the Battle Nexus so much that when she inevitably does betray them, he's already come up with a countermeasure that not only gives them an advantage in the fight, but also forces her to honor the bargain due to the show they put on.]]
* CoolTrain: Has a Mystic Train that Draxum uses in "Insane in the Mama Train".
* ClassyCravat: Wears a violet one in human form.
* DiscOneFinalBoss: [[spoiler:She's set up as the new main villain of Season 2 after Baron Draxum is depowered and the Shredder is brought under her control, only to lose control of the latter soon after enacting her masterplan.]]
* EveryoneCallsHimBarkeep: It's never mentioned what her real name is, and she even refers to herself as "Big Mama" when speaking in the third person
* EvilIsNotAToy: [[spoiler:Despite her countermeasures, she ultimately still ends up losing control of the Shredder, ending up severely injured and her hotel being destroyed.]]
* EvilVersusEvil: She's opposed to Baron Draxum, but only because she wants to mutate people to drum up more contestants for the Battle Nexus.
* FriendlyEnemies: [[spoiler:With [[AmicableExes her ex-boyfriend Splinter aka Lou Jitsu]]. When she isn't threatening the lives of him and his sons, she exhibits a clear attraction towards him. Splinter in turn can't help but maintain a slight torch towards her as well]].
* HasAType: If her history with Lou Jitsu and her present day reaction to Bullhop is any indication, she's attracted to men who can dance.
* ILied: She frequently alters the terms of her agreements at the last second to solely benefit herself.
* ImpaledWithExtremePrejudice: [[spoiler:In the BadFuture at the beginning of the movie, Big Mama's corpse can be seen impaled upon a girder amongst the rubble.]]
* ImpossibleHourglassFigure: In her human guise.
* InterspeciesRomance: She was quite taken by Bullhop when he impresses her with his skills on the dance floor. [[spoiler:In the past, she was in a relationship with Lou Jitsu, before he was turned into Splinter. Later episodes show that she still has feelings for him and even outright helps the turtles and their allies when she hears that Splinter's life is in danger.]]
* {{Irony}}: [[spoiler:Big Mama seals the populace of New York and the Hidden City in an orb in "Battle Nexus: New York" as a bargaining tool against the Turtles. This ends up ''helping'' the Turtles as this is before Big Mama loses control of the Shredder, and significantly diminishes the risk of Shredder killing everyone in New York and the Hidden City.]]
* ObviouslyEvil: She's a Jorōgumo, and runs a hotel which freely streams the Battle Nexus, which she casually describes in a manner that indicates that its contestants don't generally survive. Leonardo was the only one who was rightly suspicious of her.
* PerfectlyCromulentWord: She's fond of using grandmother-like designations or descriptions which often aren't real words. Baron Draxum is apparently familiar enough with this trait that it annoys him enough to tell her to knock it off when they first meet again.
* PurpleIsPowerful: Her main color motif in both youkai and human form, signifying the position of power she holds in her hotel and the Battle Nexus.
* SeductiveSpider: Big Mama is a spider Yokai known as the Jorogumo. Like the mythological creature she takes the form of a beautiful woman to lure in unsuspecting victims to become fighters for her Battle Nexus. She is very flirty with [[spoiler:Splinter/Lou Jitsu]] even after the latter learned of her malevolent nature, and many other males throughout the show.
* SilverFox: Her status as a youkai makes it difficult to determine exactly how old she is, but it's noted within the show that she wears her age very well.
* TermsOfEndangerment: She's prone to giving everyone cutesy nicknames even as she threatens them or tosses them into life-or-death battles for her own amusement. [[spoiler:Her genuine feelings for Lou Jitsu, her "snuggle muffin beefcake", did not stop her from kidnapping him and throwing him into the Battle Nexus.]]
* TsuchigumoAndJorogumo: She's an attractive woman that turns into a GiantSpider youkai. Her backstory with [[spoiler:Lou Jitsu]] even borrows closely from classic jorōgumo tales of men being enticed by the youkai's human guise. However, her spider form's bulky, fur-covered design is more typical of the male tsuchigumo (or the even more monstrous ushi-oni).
* VillainousCrush: Shown to have some feelings towards [[spoiler:Bullhop]] after her dance with the latter, and has a history with [[spoiler:Lou Jitsu]] as it turns out. [[spoiler:She and Lou used to actually be a couple...before she revealed her true form and kidnapped Lou to become a fighter in the Battle Nexus. [[AmicableExes She actually is still attracted to him when she meets him as Splinter, even moreso now that he's a mutant in fact.]] And in "Rise" when she hears that his life is in danger, she helps out the turtles.]]
* VoluntaryShapeshifting: She has a sort of mystical device her and her workers wear, which allow her to look human.
* WhiteHairBlackHeart: Has white hair but she's an AffablyEvil yokai.
* {{Youkai}}: She calls herself and the beings who work under her as such, and is modeled off (if not outright) a Jorōgumo.

* AllThereInTheManual: Their names are never spoke out loud.
* BountyHunter: Their job means they're loyal to whoever pays the, or in the council's case, willing to have their time working for the Baron forgiven if they do as ordered.
* CastingGag: Fred Tatasciore previously voiced Rocksteady in the 2012 series, who was also a big guy with a Russian accent in a duo who battle the Turtles. He's also had experience voicing buff characters with Russian accents besides a Turtles' villain.
* HuskyRusskie: One of them has a Russian accent, which makes little sense since they're from an underground city in New York.

* CoolUncle: While he isn't his uncle, his relationship with the turtles gives off this vibe.
* DemBones: He's a sharply dressed living skeleton. He sometimes uses his left arm as a cane.
* DeadpanSnarker: Hueso is definitely sarcastic enough to deal with Leo's antics.
* HeroOfAnotherStory: "Portal Jacked!" shows that he has a troubled history with his pirate brother (who dragged him into his crimes).
* JerkWithAHeartOfGold: He doesn't like having the Turtles in his pizzeria, and is always quick to reject going along with their antics (often being dragged along anyway) due to how much they annoy him. That being said, he's willing to show respect when he feels they've earned it.
* MeaningfulName: His name means "Mister Bones" in Spanish.

* {{Gonk}}: Courtesy of being made completely of flesh and no bones.
* MeaningfulName: "Piel" means "skin" in Spanish.

* GenkiGirl: She's lively and energetic.
* GracefulLadiesLikePurple: Her attire is in different shades of purple.
* IJustWantToBeNormal: Expresses this wish in her debut episode since she turns out to actually be a yokai. Ironically on a day April's trying to appeal to be normal ''to her''.
* LosingAShoeInTheStruggle: She helps the Turtles beat up the Foot Clan that attack April and her, but in the aftermath, noticed her boots were gone after she went back to human form. [[spoiler: This was due to the shoes being part of Shredder's armor with the Foot Clan having managed to grab them during the fight.]]

[[folder:"The Crying Titan" '''(UNMARKED SPOILERS)''']]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/dead_krang.png]]

An ancient being who granted Oroku Saki's wish for power by turning him into the Shredder. It may also be the creature inside the Crying Titan, and thus the source of Empyrean and all Yokai's power. And on top of that appears to be a member of the Krang.
----
* AbusivePrecursors: It's implied that it's part of an alien race who ended up creating yokai, but this one in particular created the Shredder's armor.
* AmbiguousSituation: Karai assumes it was an {{oni}}, but its resemblance to Krang suggests it may be of extraterrestrial origin. It's also possible it's the pilot of the Crying Titan, meaning it may be long dead.
* GreaterScopeVillain: It created the Shredder and possibly all {{yokai}}, but it's only seen in flashback. If it's the being in the Crying Titan, then it appears to have already died or gone dormant.
* JackassGenie: It gave Oroku Saki the power to protect the Foot Clan, but it also turned him into a power-hungry tyrant.
* LastEpisodeNewCharacter: It's only shown in the series finale.
* MythologyGag: Its appearance is clearly modelled after Krang, which brings to mind the 2003 cartoon version of the Shredder who was an alien that took over the identity. It also emits the same screeching sound as the 2012 cartoon incarnation of Krang. If it's also the pilot of the Crying Titan, then it references Krang's android body from the 1987 series being capable of growing in size.
* NoNameGiven: Karai doesn't identify it by any name.
* {{Oni}}: Karai describes it as "an oni", though [[CallAPegasusAHippogriff it doesn't bear much resemblance]] to the typical depiction, and she is very much mistaken to its true nature as an alien.
* WalkingSpoiler: Its existence reveals the true origin of the Shredder, and possibly all {{yokai}}.

->'''Voiced By:''' Creator/ThuropVanOrman

A ridiculously friendly Capybara mutant.
----
* BewareTheNiceOnes: "Todd Scouts" shows that he can be plenty dangerous when he has to defend himself, specifically because he can summon hoards of forest critters to overwhelm his opponents.
* CloudCuckooLander: Todd is a sweetheart, but definitely has his moments of oddness.
* CoolUncle: While he isn't their uncle, Todd has this relationship with the turtles.
* FriendToAllLivingThings: His kindness extends to all animals, and they in turn love him. This also means he has a startling degree of control over all wildlife, as demonstrated in "Todd Scouts" when he summons hoards of forest critters to fight off the [[DepravedDentist rogue dentists]] [[ItMakesSenseInContext pursuing him and the turtles]].
* GoodIsNotSoft: In "Todd Scouts", when the turtles and him are attacked by rogue dentists, he essentially goes [[Anime/DragonBallZ Super Saiyan]] in order to defeat them.
* HairOfGoldHeartOfGold: He has a blond hairdo, and is unequivocally the most genuinely kind of the cast.
* HeroesLoveDogs: He's introduced enthusiastically manning a dog shelter in "Repo Mantis".
* HiddenDepths: [[spoiler:"Anatawa Hitorijanai" reveals that he's also a master blacksmith and keeps a forge underneath his home.]]
** He also has some knowledge of Japanese history since he points out that ninjas first used repurposed farm tools as weapons.
** In the opening of the Movie, he can be seen fighting with the resistance.
* NiceGuy: His main defining feature is his sheer niceness towards everyone, even blatantly evil characters like Draxum's makeshift League of Evil Mutants. Even when he's wronged, he doesn't seem capable of holding a grudge for too long. It's so much a part of him that when Meat Sweats accidentally assimilates him, he also becomes incredibly nice.
* ObliviouslyEvil: He ended up accidentally joining the League of Evil Mutants in the titular episode because he thought it was just a friendly get-together. He didn't really do anything while he was a part of the group though.
* PowerUpFood: He can drink his Lemonade Especial for a "Lemon Rush" which basically involves going Super Saiyan and turning his animal empathy up to rally an [[ZergRush unstoppable rush of animals]].
* SmallRoleBigImpact: [[spoiler:He creates gardening tools for the Turtles to use as replacement weapons in the series finale, which, due to the Turtles' Hamato Ninpo, transform into their iconic weapons.]]
* TenderTears: He sheds these when he thinks the turtles aren't taking him seriously in "Todd Scouts".
* TrademarkFavoriteFood: Lemonade; he's constantly shown making it.

A bellhop turned mutant bull/dance aficionado.
----
* CrouchingMoronHiddenBadass: Despite his clumsiness following his transformation, and lack of skill as a fighter/ninja, he successfully infiltrates Big Mama's party and almost finishes the turtles' mission on his own.
* IKnowMortalKombat: He learns to dance well enough to impress Big Mama by playing the turtles' DDR game.
* TheKlutz: Post-transformation, he basically the epitome of this. Was notable quite graceful beforehand, and attributes said klutziness to not being used to being a towering, top-heavy bull.
* OurMinotaursAreDifferent: He was turned into a humanoid bull, akin to a minotaur.
* NoCelebritiesWereHarmed: If being a bellhop and a klutz wasn't enough, his human form is a dead ringer for Creator/JerryLewis. Even after being transformed, he once flees a dance, leaving a shoe behind, a la ''Cinderfella''.
* StealthPun: He's quite beefy.
* TheThingThatWouldNotLeave: The turtles originally planned an appreciation day to make up for turning him into mutant. This stretches across two weeks.

A professional wrestler once considered unbeatable, he was defeated by Leonardo by accident and has sworn revenge against the turtles for ruining his perfect record. He's later bitten by an oozequito and mutated into a polar bear.
----
* BearsAreBadNews: His motif as a wrestler has him dress as such, he really did became a bear however when he mutated.
* BrightIsNotGood: He wears what appeared to be a white bear pelt and considered an icon to his fans, But his personality is that of a petty arrogant cheating jerkass.
* BritishTeeth: Even before his mutation, his teeth were crooked and yellow.
* BrokenPedestal: Raph looks up to him until it's discovered that he is willing to cheat to win. Though Raph is back to being his fan in Ghostbear's next appearance.
* EmpoweredBadassNormal: He's able to take on the turtles with nothing but his strength and dirty tricks, before he eventually gets bitten by an Oozesquito in his third appearance.
* EvilIsPetty: After losing his wrestling title to the turtles (by accident no less), he always seeks to get even with them in petty ways. The turtles literally use this against him in 'Late Fee'.
* IntangibleMan: Becomes this after his mutation, which makes his name all the more fitting.
* JerkAss: His debut episode shows how much of a jerk he is, and has dedicated himself to giving the turtles a HORRIBLE time as such, whether it be returning a DVD or causing them to fight one another.
* {{Revenge}}: His goal is to get revenge on the turtles for ruining his professional wrestling career.

A goldfish that was formerly a pet to Splinter and the turtles. She was accidentally flushed down the toilet and mutated after eating an oozesquito. She came back for revenge, but turned out was just a plan to scare the brothers about the dangers of lying.
----
* AffectionateParody: Her debut is a parody of horror movies, in particular ''Film/IKnowWhatYouDidLastSummer'' (sharing the hook weapon of the film's antagonist), but she also does [[Film/TheRing Sadako's]] famous "well crawl".
* BaitAndSwitch: It seemed like Piebald was a villain and was out to get the turtles, but she turned out to be a good guy after all. Her acting evil was merely part of Splinter's plan to teach the boys a lesson. Piebald actually seems quite friendly.
* DarkIsNotEvil: She utilizes quite a few fear tactics and is in a dark cloak, but turns out to be helping Splinter teach a lesson to the Turtles about lying. She also doesn't seem to hold a grudge against the Turtles at all, at best saying that trying to cover up her apparent death wasn't really their best moment.
* FishOutOfWater: Quite literally. Being a mutant enabled her to walk on land.
* HappilyAdopted: She was adopted by Splinter and the turtles as a pet until she was flushed. At the end of the her debut episode, Piebald seemed on very good terms with Splinter still. She even refers to him as her father.
* HooksAndCrooks: Her main weapon seems to be a hook.
* {{Invisibility}}: Seemingly one of her main abilities.
* NiceGirl: Was actually one after all.
* OneShotCharacter: She only appears in "Flushed, but never Forgotten".

* HostileAnimatronics: He's a former SuckECheeses mascot that turned into a murderous robot as a result of a mishap in his circuitry.
* NonStandardCharacterDesign: Barring his robotic implements, he looks more like a retro cartoon character, having PieEyes. Given that he's a cartoon mascot who has likely been around for a while (and who has had multiple iterations over the years), it's likely the retro design aspects are a holdover from previous iterations.

-->'''Voiced by:''' Ramone Hamilton (English), Pamela Cruz (Latin American Spanish)

A young [[MeaningfulName stock boy]] who runs an online video show that he's hoping will make him famous.
----
* AdaptationNameChange:
** He's a young version of franchise-wide nemesis Baxter Stockman, and his surname is changed to "Stock''boy''" to play upon this.
** His trademark Mouser robots appear in "The Mutant Menace", but he refers to them as "microbots".
* AdaptationalNiceGuy: He's arguably less villainous than he usually is. While Stockman was an evil scientist who performed on living organisms, Stockboy primarily wants to make money and a name for himself by making videos, which he does by putting people in danger, but is still far less actively evil than usual.
* AgeLift: He's much younger than how he appears in most iterations, going from an adult man to a little boy.
* BadassNormal: Stockboy doesn't have any powers, but is intellectually gifted for someone of his age. He has the Gumbus robot and his microbots to prove it!
* CanonCharacterAllAlong: He's initially presented as a new character, and just a DistressedDude whose misfortune brings the main characters to the plot, but the end of his debut episode reveals that he's this series' incarnation of TMNT antagonist Baxter Stockman.
* ChildProdigy: Despite being a little kid, his intelligence is enough to rival that of both Donnie and the Purple Dragons.
* CutLexLuthorACheck: Stockboy wants money, but only thinks to use his advanced robotics for a ScoobyDooHoax meant to ''get publicity for his online videos''.
* HisNameReallyIsBarkeep: He's a grocery store stock boy, makes videos under the name "[[XtremelyKoolLetterz Stockboi]]", and his family name is "Stockboy". April makes fun of him having such an on-the-nose name.
* MythologyGag: He has the hairstyle of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] version, serving as a quick hint to his identity in his debut.
* RobotMaster: Like most versions of Baxter Stockman, he's creates robots for his schemes, though his initial one is piloted.
* ShorterMeansSmarter: Justified due to being younger, although overall it's still a VagueAge whether he's a ChildProdigy or TeenGenius.
* TruerToTheText: Baxter Stockman is traditionally depicted as working with the Foot Clan, which started back in the 1987 cartoon, with (almost) all later adaptations [[LostInImitation using this approach]] in some way. But in ''Rise'', Baxter Stockboy has no ties to the Foot Clan at all, which, despite Stockboy being [[AgeLift younger]] and [[AdaptationalNiceGuy slightly less evil]], is actually a bit closer to the original [[ComicBook/TeenageMutantNinjaTurtlesMirage comics]], where Baxter was an independent antagonist who never worked with Shredder or the Foot Clan (and possibly never even knew about them to begin with).
* YoungerAndHipper: In previous incarnations, he's an adult. Here, he's a young boy. Hence why [[AdaptationNameChange he's called "Stockboy" instead of "Stockman"]].

* FateWorseThanDeath: She's a youkai who's stuck being the main character of a kid's show, and thusly almost never hears the screams she needs to be more than an inanimate doll.
* KryptoniteFactor: While the fearful screams of others empowers her, laughter weakens her.

A club at April's school who moonlight as criminals.
----
* AdaptationDeviation: Probably among the most significantly reinvented aspects of the ''TMNT'' mythos for this series, even after Baxter Stockboy. Rather than being a New York gang who works under the Foot Clan, they're a tech club comprised primarily of three teenagers who commit cyber-crimes. The gang also have no relation to the Foot Clan, with the Purple Dragons generally being a subsidiary of that organization.
* AdaptationalIntelligence: Previous iterations of the Purple Dragons weren't portrayed to be very smart, but in Rise, they're quite talented with computers and other tech based activities/crimes.
* BigThinShortTrio: Jeremy is the "Big", Jase is the "Thin", and Kendra is the "Short".
* ButtMonkey: Jase is regularly mocked and abused by the other Purple Dragons. When Donatello joins the group, Jase is initially excited because he believes it means he's no longer at the bottom of the totem pole, only for Kendra to immediately squash his hopes on that matter.
* TheCracker: They use their hacking skills for crimes, including robbing a bank. They also just steal things physically.
* EvilIsPetty: Their second appearance is them trying to kill Donnie's brothers with his own tech, simply in revenge for their first confrontation.
* IKnowYourTrueName: They call Donnie by his alias ''Othello Van Ryan'' in "The Purple Jacket". However, they call him by his real name in "The Purple Game", likely learning through hacking his gamer profile.
* InNameOnly: The Purple Dragons are generally a street gang subsidiary to the Foot Clan in other incarnations, whereas this one is a tech club with no relation to the Foot.
* NerdyBully: A tech club with a smug sense of superiority towards other tech geeks, including hanging them on their computers by the underwear. That's before they turn out to be outright criminals.
* SmurfettePrinciple: Kendra is the only female Purple Dragon.
* {{Tuckerization}}: All three of them were named after crew members who worked on the 2012 series.
* WeUsedToBeFriends: Subverted--April and Kendra have known each other since they were in Kindergarten, but it's unknown if they were ever actually friends at any point before the start of the series.

An actor and martial artist who opened up several dojos across New York, replacing ones formerly owned by Lou Jitsu.
----
* AdaptationNameChange: He's based off Chris Bradford from the 2012 series, but this incarnation has a more European name due to being [[NoCelebritiesWereHarmed based off of]] Creator/JeanClaudeVanDamme.
* AdaptationOriginConnection: Inverted. In the 2012 show, Chris Bradford was a high-ranking member of the Foot Clan and was taught martial arts by The Shredder. Here, Kristoff has nothing to do with the Foot Clan, instead being a self-proclaimed rival of Master Splinter.
* AmbiguouslyRelated: His top student bears a notable resemblance to him and is especially focused on pleasing him, suggesting they could be father and son.
* DemotedToExtra: In the 2012 series, Chris Bradford was Shredder's [[TheBrute brutish]] and [[CoDragons one of his high-ranking underlings]], appearing in every season of the show. Here he's a one-off bad guy with no affiliations with the Foot Clan.
* EvilCounterpart: While Splinter was mutated against his will, but makes the most out of his new form, Kristoff allowed himself to become a monster by combining with his komodo yokai for more strength.
* {{Expy}}: On top of being a Creator/JeanClaudeVanDamme ripoff, he also borrows a lot from ''Film/TheKarateKid'' antagonist [[Characters/TheKarateKidJohnKreese John Kreese]]; black-clad sensei of a ThugDojo that encourages his students to use his teaching to hurt innocent people and reacts to losing fair-and-square [[SoreLoser with an irrational thirst for vengeance]]. Even his dojo's motto -- "strike fast, strike hard, no mercy" -- is the similar to [[Characters/TheKarateKidCobraKaiAndAssociates Cobra Kai's]].
* {{Jerkass}}: He and his students regularly go to the last remaining Lou Jitsu dojo in New York just to torment the students that can't even fight back.
* NoCelebritiesWereHarmed: He's pretty clearly a pastiche of Creator/JeanClaudeVanDamme.
* TeamMemberInTheAdaptation: Inverted; unlike his 2012 counterpart, he has no relation to the Foot Clan.

-----
* AlliterativeName: '''M'''arcus '''M'''oncrief and his famous role of '''J'''upiter '''J'''im.
* TheCloudcuckoolanderWasRight: [[spoiler:Played with. While he considers his former sidekick Red Fox and the scorpion creature he tracks down in his second appearance as aliens, they actually ''do'' turn out to be non-human. [[RightForTheWrongReasons Specifically, a Yokai and a mutant]].]]
* HeelFaceTurn: [[spoiler:While still crazy, he's much more benign by the end of his first appearance, and makes a genuine effort to be a superhero in his second appearance (albeit largely ineffectual).]]
* LostInCharacter: [[spoiler: Not only does his apartment look exactly like a set piece from his films, but he's convinced that fans costumed up as enemies he's faced off against are real. And he sets his sights on the turtles...]]
* MeaningfulName: An old definition of Marcus means "to harvest". In his first appearance, [[spoiler:he collects cosplayers dressed as monsters and puts them on display.]]

A wrestling referee and broadcaster.
----
* AlliterativeName: '''J'''essica '''J'''aclyn.
* CombatReferee: Especially when her wrestling matches become no-rules grudge competitions.
* LargeHam: Her career as a professional wrestler announcer, naturally she puts on an [[Main/FunPersonified excitable]] announcer personality.
* MsFanservice: She is an attractive, curvy woman with a large bust, flexible legs, HartmanHips, and managed to get in a BoobsAndButtPose in her debut episode.
* OneShotCharacter: She solely appears in one episode and is never seen again in the series outside of a single brief cameo.
* PerpetualSmiler: She is usually seen with '''[[Main/StepfordSmiler a big smile on her face]]'''.
* ScrewTheRulesIMakeThem: Throughout her debut episode, she constantly keeps changing the regulations of the wrestling matches to keep things exciting. The wrestling match between the Turtles and Ghost Bear ultimately ends with her declaring herself the victor.
* XanatosSpeedChess: Even when the unexpected keeps happening during her wrestling matches, like Leo accidentally falling on top of and knocking out Ghostbear when she was able to declare him champion, ''[[Main/TheShowMustGoOn she just rolls with it]]''.

-->'''Voiced by:''' Eric Bauza

A famous action movie star that the Turtles are a big fan of and whose films Splinter uses as training material. We later find out that there's more to him than meets the eye...
----
* AdaptationPersonalityChange: Most previous incarnations of Hamato Yoshi were disciplined and peaceful men who were heavily devoted to tradition. Lou Jitsu, on the other hand, was a loud and bombastic movie star who completely blew off his clan's duties for fame and fortune.
* AdaptationalAttractiveness: To go with the AdaptationPersonalityChange above, while most versions of Hamato Yoshi are distinguished but otherwise reserved middle-aged men, if not older, Lou Jitsu happily flaunted his good looks and sex appeal in his prime.
* AnimalMotifs: He has a phoenix as a main decorative motif on his jumpsuit symbolizing his metaphorical death as Lou and his rebirth as Splinter.
* ADayInTheLimelight: "Goyles, Goyles, Goyles" focuses on the day he became mutated into Splinter and took the turtles that would become his sons.
* BadassNormal: He was a former Battle Nexus Champion and seemingly the only human to ever have won the Battle Nexus. He was so skilled that Baron Draxum, whose opinion of humans is low, decided to use his DNA for his mutant army. Given that he's really Hamato Yoshi, this shouldn't come as a surprise.
* BlaxploitationParody: His movies reek of an Asian spin on Blaxploitation and are heavily played for comedy. The fact that he took a stage name based on a martial art instead of using his real name of "Hamato Yoshi" only amplifies the satirical angle.
* BrokenAce: A handsome, famous, not to mention genuinely skilled martial artist... who was kidnapped and forced to be a gladiator by his own lover (who turned out to not even be a human at all), resigned himself to be a warrior alchemist's guinea pig, and was ''then'' turned into a rat-human hybrid for trying to save the innocent test subjects of said alchemist.
* CanonCharacterAllAlong: "The Evil League of Mutants" heavily implies, and "Shadow of Evil" confirms, that he's this series' incarnation of Splinter. "Insane in the Mama Train" further reveals that Lou Jitsu is just a stage name and his actual name is indeed Hamato Yoshi.
* CharacterCatchphrase: He shouts "Hot Soup!" in his films. It's so iconic that he even has a video game called "Hot Soup!" In fact, it's a bit of {{Foreshadowing}} when Raph shouts it in "Origami Tsunami" because he was imitating his father.
* ChekhovsGunman: After he's introduced in "Origami Tsunami", get used to seeing his face since "The Evil League of Mutants" reveals that he's not just an action film star...
* ChickMagnet: Lou Jitsu was known to be a ladies' man. A flashback in "Turtledega Nights: Rat Man" has a cat yokai swoon over him (and the same one swoons over him years later), while "The Ancient Art of Ninja Hide and Seek" and "Many Unhappy Returns" reveals that he has history with Big Mama.
* CompositeCharacter: Combined with SparedByTheAdaptation, but much like [[WesternAnimation/TeenageMutantNinjaTurtles1987 his 1987]] and [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 incarnations]], he's a still living Hamato Yoshi who mutates into Splinter, not a dead man whose pet becomes mutated and the Turtles' mentor.
* CoolShades: The sunglasses he always wore were gold and shiny.
* CutenessProximity: "Goyles, Goyles, Goyles" had him ''coo'' over the baby turtles that would eventually become the "Mad Dogs", even giving pre-mutated Leo and Raph the names "Green" and "Green #2"
* DespairEventHorizon: "Goyles, Goyles, Goyles" has him exhausted from fighting in the Battle Nexus, to the point that he's sworn off fighting.
* DelinquentHair: He rocked an epic pompadour.
* FriendToAllLivingThings: "Goyles, Goyles, Goyles" had him befriend a rat when he was stuck meditating in his cell and he cooed over the turtles. Unfortunately, his rat friend bit him seconds before Lou was covered in mutagen...
* HeroOfAnotherStory: Lou had an interesting life; aside from being a famous movie star, he's also a former Battle Nexus Champion and has history with Big Mama too!
* ImprobableWeaponUser: He was known for this, with Splinter trying to train his sons with movies involving ladders and fish in "The Evil League of Mutants". Baron Draxum actually recognized this fighting style from the turtles, making him realize that Lou was still out there.
* InterspeciesRomance: He was a ladies' man both in the human and Youkai realms. A flashback shows him making a cat mutant swoon with a flirtatious wink, and it's implied in "The Ancient Art of Ninja Hide and Seek" that he had a romantic history with Big Mama, then confirmed in "Many Unhappy Returns". Granted, he wasn't aware that Big Mama was a Youkai at the time before she revealed her true form, [[FailedASpotCheck despite the really obvious signs.]]
* LadykillerInLove: He genuinely fell in love with Big Mama and was planning to propose to her. Unfortunately, that pretty much flew out the window after she revealed her true form to him and kidnapped him to become a Battle Nexus combatant. As shown by the way he looks at the picture of him and Big Mama when he retrieves it he likely still can't help but hold a candle for her.
* MrFanservice: He's a ''very'' handsome man. The show also likes [[FemaleGaze emphasizing his chest and backside]].
* MundaneUtility: Downplayed. Hamato Yoshi used his impressive martial arts skills to become a movie star [[StageName called Lou Jitsu]] rather than commit to his duties to stopping the Foot Clan.
* NeverFoundTheBody: Draxum mentions that the last he saw of Lou was when his lab was destroyed and he took the turtles with him. Because Lou Jitsu would eventually become Splinter.
* NoCelebritiesWereHarmed: His name, along with him being a movie star martial artist known for improvisation is most likely based on Jackie Chan with a little Bruce Lee on the side.
* PunnyName: It's a play on either "Jiu Jitsu", a type of martial art or "Ninjutsu" which is the fighting style of ninjas. The latter is probably forshadowing that Lou is Splinter.
* RageBreakingPoint: "Goyles, Goyles, Goyles" has him absolutely exhausted from the Battle Nexus fights and swearing off fighting...until he learns that Draxum wants to mutate the baby turtles for his army. Cue ''pissed off rampage''.
* ShowWithinAShow: He's the star of various action films that the turtles watch and Splinter uses as teaching material. "Hot Soup: The Game" even shows he had his own video game based on him. Of course it makes sense Splinter would be so attached to these films and video game since he ''was'' Lou Jitsu.
* SignificantDoubleCasting: He has the same voice actor as Splinter. Because they're one and the same.
* SparedByTheAdaptation: Combined with CompositeCharacter, but much like his 1987 and 2012 incarnations, he's a still living Hamato Yoshi who mutates into Splinter, not a dead man.
* StageName: Lou is this to Hamato Yoshi/Splinter.
* TwoAliasesOneCharacter: He's Splinter before he was mutated into a rat man by Baron Draxum.
* WalkingSpoiler: It's safe to describe him as an action star that the Turtles are fans of. Anything past ''The Evil League of Mutants'' and ''Shadow of Evil'' however...

!!Villains:
[[folder:Baron Draxum]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/barondraxum_1.png]]
-->'''Voiced by''': Creator/JohnCena [EN](Season 1), Creator/RogerCraigSmith [EN](Season 2), Raúl Anaya (Latin American Spanish)

An unspecified {{Youkai}} warrior and alchemist from the "Hidden City." He is also known as the "Maker of Mutants." As the self-proclaimed protector of all yokai-kind, Baron Draxum seeks to mutate humans into mutants.
----
* AffectionateNickname: Mikey and April call him "Barry" [[spoiler:once he steps down from being a villain.]]
* AmbiguouslyGay: In a flashback Draxum is seen ogling Lou Jitsu, who's striking a dashing pose with his shirt torn open. [[spoiler:Draxum is also considered to be the Turtles' second father, and it's implied that he still has a fondness for Splinter]].
* AntiVillain: He's not really antagonistic towards the Turtles, and his goals seem to have the aim of the protection and betterment of youkai kind. However, he lacks empathy for humans and seems to be plotting genocide by conversion.
* BadassBaritone: Has a deep, booming voice provided by John Cena. Roger Craig Smith replicates it fairly well after taking over the role.
* BeautifulAllAlong: [[spoiler:Underneath the mask he's quite handsome, at least by human standards]].
* BeingGoodSucks: [[spoiler:In the series finale, he briefly complains that life was a lot easier when he didn't like the Turtles or Splinter, but still finds himself having to stop Shredder from simply killing Splinter.]]
* BigBadEnsemble: He's one of the major antagonists of the series, the other being Big Mama. Draxum is responsible for creating the Oozesquitoes [[spoiler:and the Turtles]], which will go on to create several villains of the Turtles' RoguesGallery, while Big Mama wishes to use said mutants as contestants for the Battle Nexus.
** BigBadWannabe: [[spoiler: Ultimately, he and Big Mama are dethroned by the revived Shredder as the main villain.]]
* BrutalHonesty: When asked if mutation would hurt by a pizza delivery boy who'd stumbled into his hidden city, he responded by telling him that if was doing it right, [[BluntYes Yes.]]
* CardCarryingVillain: He calls his VillainTeamUp the "Evil League of Mutants".
* CastingGag: John Cena voices a villain who has the ability to turn invisible in reference to Cena's [[Memes/{{WWE}} "You can't see me"]] catchphrase and the memes surrounding it.
** Him being a villain could be seen as one. Online WWE fans have been very vocal in their desire for John Cena to undergo a FaceHeelTurn, but for more than a decade, he's been the same uncomplicated good guy. [[spoiler:There's also irony to be found in the fact that Baron Draxum makes a HeelFaceTurn after Cena stopped voicing him.]]
* CharacterDevelopment: [[spoiler:By the end of "Repairin' the Baron", he seems to be trying to make a genuine effort to live alongside the human race. Also, through no small effort on Mikey's part, Draxum has gradually been reconciling with the TMNT family, proving to them that he's a changed man through heroic, selfless acts.]]
* TheComicallySerious: He's got a fairly serious personality, but has his fair share of comedic moments, often from [[NotSoStoic when his stoicism is broken]]. Case in point:
--> '''Big Mama''': Scrambulent to see you again, Baron Draxum, but you really must learn to use the ''dimbly door''.
--> '''Baron Draxum''': ''You'' must learn to use ''real words''!
* CurbStompBattle: He utterly trounces the turtles during their first battle despite their best efforts. Donnie is the only one who manages to get a hit in, and that was by complete accident as Draxum was blindsided by Donnie's out-of-control staff.
* CrushFilter: When he sees the turtles for the first time, this filter is applied over them. It's more him marveling at the success of his experiment though.
* DarkMessiah: He has proclaimed himself as the Protector of Mutantkind. His means of doing so involves plotting genocide on the human populace via conversion. [[spoiler:After obtaining the Shredder armor, he decides to just eradicate the human race the old-fashioned way.]]
* DecompositeCharacter: [[spoiler:His personal enmity with Splinter/Hamato Yoshi is similar to previous incarnations of Shredder and Splinter, both of whom had never met in this continuity due to the Shredder being a centuries-old demon. He also briefly controls the Foot Clan, and tries to become the Shredder, but ultimately fails due to [[EvilIsNotAToy underestimating]] how dangerous both the group and armor are.]]
* DiscOneFinalBoss: Draxum is initially introduced as the main villain of the series, but by mid-Season 1, the Foot Clan take over as the main antagonists, with Draxum working with them. [[spoiler:Even taking over the Clan seems to have been part of their plan, with their plan to have Draxum wear the armor [[UnwittingPawn so that it'll eat his life force]]. By Season 2, he's no longer the main villain, and [[HeelFaceTurn ends up joining the heroes]] too.]]
* EmperorScientist: The head of an underground mutant city and an alchemist to boot.
* EvilCounterpart: He seems to be a bit of one to Donatello, having a fixation on his scientific pursuits that borders on unhealthy. He even gets a CrushFilter when seeing the Turtles for the first time, apparently brought to tears by the perfection of their mutations.
* EvilVersusEvil: Baron Draxum and Big Mama don't get along with Big Mama wanting to use Draxum's Oozesquitoes to make more warriors for her Battle Nexus. Draxum on the other hand wants to use them to get rid of the "human problem" and is not pleased that Big Mama is using his Oozesquitoes.
* EvilIsHammy: John Cena brings a lot of his showmanship to Draxum. Even at his most serious, his every word is a dramatic declaration. And that's not getting into him going full-ham while singing the solo for "Warring Warrior Scientist".
* EvilIsNotAToy: [[spoiler:He underestimates the power of the Shredder's armor, trying to take its power for himself, only to end up [[{{Irony}} having his own life force drained]] as he's spat out. Later on in "Air Turtle", Draxum is on the other side of this trope when he repremands Leonardo for using a dangerous mystic artifact to enhance the abilities of a failing basketball team (which ends up turning the players into demons).]]
* EvilSoundsDeep: Again, courtesy of John Cena, who gives him a very booming voice. It remains even after Roger Craig Smith takes over the role [[spoiler:(although Draxum makes his HeelFaceTurn by the time Smith replaced Cena)]].
* EvilutionaryBiologist: His plans for mankind involve transforming them into mutants with his Oozesquitoes.
* ExpressiveMask: It's revealed in ''Repairin' the Baron'' that he's been wearing a fully-encompassing helmet the entire time, one that happens to have eye holes that are capable of emoting. [[spoiler:It falls off and breaks at the end of the episode as he saves the lives of a human woman and her child, symbolizing his HeelFaceTurn]].
* FakeDefector: [[spoiler:He complies with the Shredder's demands in the series finale, and says that he always planned on betraying Splinter and his family. It turns out to be a ploy to try and ambush Shredder that is doomed the moment he enacts it, and reaffirms he's genuinely changed.]]
* GeniusBruiser: An intelligent alchemist responsible for creating the Ooze, and is no slouch in combat, easily beating the less experienced turtles. Huginn and Muninn call him a "Warring Warrior Scientist" in their song.
* GoodCostumeSwitch: [[spoiler:His mask falls off and shatters on the ground while trying to save two humans in "Repairin' The Baron", which seems to cement his HeelFaceTurn. It's very telling that Draxum doesn't redon his original armor after this; instead, his outfit is now entirely nonthreatening, consisting of a kimono and a hairstyle very similar to Splinter's.]]
* GreenThumb: He is able to summon large purple vines for a variety of purposes, such as strangulation, transportation, and even making a [[{{ChainsawGood}} chainsaw]] for some reason.
* HeelFaceTurn: [[spoiler:At the end of "Repairin' the Baron", he decides to attempt to live among the humans rather than try to destroy them after a lot of coaxing from Mikey. He still hates humans, but seems to be making a greater effort to tolerate them. Later on in "Hidden City's Most Wanted", Draxum finally reconciles with Splinter, apologizing for his past misdeeds against the TMNT family before giving himself up to the Hidden City police so that Splinter and Michelangelo can escape (Splinter and Mikey return the favor and bust Draxum out of prison later along with the rest of the TMNT family who had each also gotten arrested during their own various misadventures in the city). In "Battle Nexus: New York" Draxum risks his life several times trying to free the citizens of New York from a mystic artifact that Big Mama had trapped them all in.]]
* HowTheMightyHaveFallen: [[spoiler:He's living in an apartment room unable to do anything but shout empty threats at people come his return in "Repairin' the Baron", and that was after Mikey originally found him homeless on the streets. Due to the Shredder draining his life force, he can't even manifest his vines, at least not until the end of the episode. Sometime after his HeelFaceTurn, he regains his old strength, allowing him to manifest his vines easily once again.]]
* {{Jerkass}}: Draxum is very blunt and rather uncompromising, and also casually ruins the lives of people he comes across. [[spoiler:After his HeelFaceTurn, he starts [[JerkWithAHeartOfGold warming up]] to the Turtles and humans, although not by much.]]
* JerkassHasAPoint: [[spoiler:He tells Splinter in "Hidden City's Most Wanted" that he wouldn't even ''have'' his sons if it weren't for Draxum experimenting on him, which Splinter ends up agreeing with.]]
* LackOfEmpathy: He doesn't really have very much regard for human life, with many having their lives ruined due to being mutated by his Oozesquitoes, and had no qualms with manipulating the Foot Recruit to [[spoiler:take over the Foot Clan]]. [[spoiler:Even after his HeelFaceTurn, he rules the cafeteria with an iron fist, and still seems to want to dabble with Oozesquitoes before April tells him to knock it off. He also tells Splinter that he gave him purpose by using his genes to create the Turtles in "Hidden City's Most Wanted", trying to deflect that he ultimately destroyed any chance of Splinter returning to his old life, although Draxum does apologize for his actions. He also plainly states, when Splinter says that he doesn't want the Turtles seeing some of his most sensitive memories in "E-Turtle Sunshine of the Spotless Mind", that that isn't ''his'' problem.]]
* MookMaker: He apparently created the Ooze, and the Oozesquitoes as a means of distribution. He's also capable of summoning a large mutant to battle the turtles for him in the pilot.
* MoralLuck: [[spoiler: This is the crux of why Mikey considers him family. If he hadn't mutated Splinter and the turtles, the turtles wouldn't exist and would never have become a family. Draxum also argues that Splinter's life is actually better now than it was before he had his sons, which Splinter eventually accepts. That said, Mikey does acknowledge that he didn't mutate them for the right reasons and Draxum does eventually apologize to Splinter for doing so.]]
* MyGodWhatHaveIDone: [[spoiler: The look on his face when beholding the reborn Shredder at the end of Season 1 ''screams'' this as he realizes that in his paranoia towards humans he wound up unleashing what might be the ''true'' destroyer of Yokai-kind.]]
* NotSoAboveItAll: Barring his [[TheComicallySerious stoic reaction]] to most things that annoy him, he decides, after Huginn and Muninn flatter him enough, to join in on the VillainSong in "The Evil League of Mutants".
* ObviouslyEvil: He looks borderline demonic, has a deep voice, and outright tells a teenager he's going to mutate that it will hurt. [[KickTheDog If he's doing it right]].
* OOCIsSeriousBusiness: The fact that he casually swats away an Oozesquito and mostly ignores fighting the Turtles in "Shadow of Evil" tips the Turtles off that Draxum might be planning something big.
* ReformedButNotTamed: [[spoiler:Even after he decides to reconsider his campaign against the human race, he still retains much of his ruthless and prideful personality. When he takes up a job in the human world as a cafeteria worker, he runs his cafeteria more like a boot camp, where even the most minor of infractions warrant the threat of physical violence. He also hasn't completely given up on turning people into mutants using Oozesquitoes.]]
* SelfFulfillingProphecy: [[spoiler:He wants to stop the threat to youkai kind...only to find out too late that ''he'' was the one who caused it by teaming with the Foot Clan and letting them resurrect Shredder.]]
* SurroundedByIdiots: He gives off this vibe in all of his interactions. Not surprising given he's more competent and serious than any other villain in the show. [[spoiler:Or so he thought. The goofier tendencies of the Foot Lieutenant and Brute keep him from realizing that they're manipulating him into resurrecting the Shredder.]]
* SuspiciouslySimilarSubstitute: He's an armored villain whose actions [[spoiler:contributed to ruining Hamato Yoshi's life, which also resulted in the creation of the Turtles]], similar to the Shredder. Downplayed after Season 2, where [[spoiler:he becomes heroic and he and Splinter eventually bury the hatchet.]]
* TerrifyingRescuer: [[spoiler:His appearance scared the woman and child he tried to rescue, but they soften up to him after he saved them]].
* ThickerThanWater: [[spoiler:Upon finding him living on the streets homeless, Mikey decides to help him get his groove back and try to turn him around on his opinion on humans in ''Repairin' the Baron'' on account of him being the turtles' creator. Note though that this is pretty much ''only'' Mikey's opinion of the guy for much of the episode until Draxum's HeelFaceTurn at the end.]]
* ThirdPersonPerson: He will occasionally refers to himself in the third person, usually when making a BadassBoast.
-->'''Baron Draxum''': Baron Draxum does not surrender!
* UnreliableNarrator: His memories of [[spoiler: Lou Jitsu]] paint the man as [[BloodKnight a fierce warrior who enjoyed his time in the Nexus]]. The truth was less so.
* UnwittingPawn: [[spoiler: The Foot Lieutenant and The Foot Brute manipulated him into donning the Shredder Armor over the course of the first season, empowering the Shredder with his life energy to help the ancient demon revive.]]
* VillainExitStageLeft: [[spoiler:He manages to use his remaining strength to escape through a portal during the Shredder's resurrection while the Foot are distracted. Though considering Muninn and Huginn are shown searching for new employment in a following episode, he never returned home.]]
* VillainousCheekbones: As suggested by his helmet shape, he has these. [[spoiler:Ironically, they only get put on full display after he's undergone a HeelFaceTurn.]]
* WalkingSpoiler: The extent of his history with the Turtles and everything that happens to him post Season 1 reflects some massive changes and revelations within the story.
* WorthyOpponent: He holds [[spoiler:Lou Jitsu aka Splinter]] in high regard for his fighting abilities.
* WeCanRuleTogether: He wants the Turtles on his side, and offers to train them in the pilot. This is of course rejected. [[spoiler:Poetically enough, ''he'' eventually ends up joining ''them'']].
* WellIntentionedExtremist: [[spoiler:Upon hearing a prophecy about the end of youkai kind, Draxum is on a one-man quest to stop said threat. Unfortunately, he assumes that said threat is humanity...]]

[[folder:Huginn and Muninn]]
-->'''Voiced by''': Creator/TimSimons (Huginn), Creator/SamRichardson (Muninn)

Two gargoyles that are perched on Baron Draxum's shoulders.
----
* HeterosexualLifePartners: Huginn and Muninn have been close friends since their bootcamp days.
* {{Jerkass}}: Huginn seems to delight in tormenting and frightening others, as shown by his only vocalizations during his first appearance being malicious laughter. This aspect is downplayed in later episodes in favor of his friendship with Muninn.
* MythicalMotifs: Huginn and Muninn were named after the ravens perched on Odin's shoulders who flew around the world and whispered knowledge into Odin's ear. Although [[IronicName neither are very bright]].
* NiceJobFixingItVillain: "Goyles, Goyles, Goyles" reveals that [[spoiler: Huginn and Muninn accidentally destroyed Draxum's mutagen supply in their attempt to assist him in his battle with Lou Jitsu. The spilled mutagen not only created Splinter but delayed Draxum long enough for the turtles to grow and face him in the present.]]
* OutOfFocus: They only show up once in Season 2 in "Goyles, Goyles, Goyles" (which [[ADayInTheLimelight headlines]] them), due to most of their interactions being tied to Draxum, [[spoiler:who went into hiding after Season 1, and later [[HeelFaceTurn became allied with the heroes]]]], and [[WhatHappenedToTheMouse never appear again afterward]].

[[folder:Big Mama]]
-->'''Voiced by:''' Creator/LenaHeadey (English), Rocío Garcel (Latin American Spanish)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/bigmama_profile_render.png]]
[[caption-width-right:350:[[labelnote:Her human disguise]]\\
https://static.tvtropes.org/pmwiki/pub/images/bigmama_human_form_pic_4.png[[/labelnote]]]]
A shapeshifting spider youkai who runs the Grand Nexus Hotel, which operates as a hotel for humans and a hub of activity for youkai. Beneath her cheery exterior lies a rather ruthless crime boss who's always looking to expand viewership for the Battle Nexus, a popular gladiatorial arena in the Hidden City.
----
* AbhorrentAdmirer: Subverted. Even after the revelation that she's giant spider youkai, Splinter still has feelings for her. It helps that he becomes non-human.
* AffablyEvil: She seems to have some real fondness for the mutants working under her, but she runs the Battle Nexus, which is essentially blood sport. Her compliments toward Donatello's technology also seem to be, to some extent, genuine, even if it's obviously playing to his ego.
* AFormYouAreComfortableWith: She's capable of shape-shifting from her spider form into a more human-looking form, albeit a purple human.
* AmazingTechnicolorPopulation: Her human disguise has purple skin and white hair.
* BigBadEnsemble: By the end of "Bug Busters", she's become another major antagonist on equal footing with Baron Draxum (and later the Foot Clan when they ally with Draxum) due to using his Oozesquitoes to create more mutants to participate in the Battle Nexus. [[spoiler:At least that was the case until season two, where Baron Draxum undergoes a HeelFaceTurn and she's kicked out of the BigBad role by the Foot Clan once they regain control of Shredder.]].
* BigBadWannabe: [[spoiler: Following "Many Unhappy Returns", she appears discretely at the end of multiple episodes to steal away prior villains to set up her grand reveal in "Battle Nexus: New York" to turn New York into her new Battle Nexus arena. However, as soon as her plan is introduced, she loses control of her main asset, ''The Shredder'', to the Foot Recruit, with the Shredder later regaining his sentience and becoming the final villain of the series]].
* BrightIsNotGood: The true appearance of her hotel is full of bright implements with a fairly comfortable atmosphere, and Big Mama herself has a human disguise with an emphasis on very light colors. The hotel is also home to a blood sport, and Big Mama herself is one of the series' main antagonists.
* ChronicBackstabbingDisorder: Unless it's in her best interests to [[PragmaticVillainy play nice]], she will most likely betray the other party: she takes the Oozesquitoes from the Turtles in "Bug Busters" (which she provided the resources to capture) to make more Battle Nexus contestants, and her backstory involves [[spoiler:buddying up with Lou Jitsu only to kidnap him and force him to partake in the Battle Nexus (though her feelings were genuine)]]. In "Many Unhappy Returns", [[spoiler:Leonardo actually [[ExploitedTrope exploits]] her untrustworthy nature; he escalates the deal to help them in exchange for a fight in the Battle Nexus so much that when she inevitably does betray them, he's already come up with a countermeasure that not only gives them an advantage in the fight, but also forces her to honor the bargain due to the show they put on.]]
* CoolTrain: Has a Mystic Train that Draxum uses in "Insane in the Mama Train".
* ClassyCravat: Wears a violet one in human form.
* EvilIsNotAToy: [[spoiler:Despite her countermeasures, she ultimately still ends up losing control of the Shredder, ending up severely injured and her hotel being destroyed.]]
* EvilVersusEvil: She's opposed to Baron Draxum, but only because she wants to mutate people to drum up more contestants for the Battle Nexus.
* FriendlyEnemies: [[spoiler:With [[AmicableExes her ex-boyfriend Splinter aka Lou Jitsu]]. When she isn't threatening the lives of him and his sons, she exhibits a clear attraction towards him. Splinter in turn can't help but maintain a slight torch towards her as well]].
* ILied: She frequently alters the terms of her agreements at the last second to solely benefit herself.
* ImpossibleHourglassFigure: In her human guise.
* InterspeciesRomance: She was quite taken by Bullhop when he impresses her with his skills on the dance floor. [[spoiler:In the past, she was in a relationship with Lou Jitsu, before he was turned into Splinter. Later episodes show that she still has feelings for him and even outright helps the turtles and their allies when she hears that Splinter's life is in danger.]]
* ObviouslyEvil: She's a Jorōgumo, and runs a hotel which freely streams the Battle Nexus, which she casually describes in a manner that indicates that its contestants don't generally survive. Leonardo was the only one who was rightly suspicious of her.
* PerfectlyCromulentWord: She's fond of using grandmother-like designations or descriptions which often aren't real words. Baron Draxum is apparently familiar enough with this trait that it annoys him enough to tell her to knock it off when they first meet again.
* PurpleIsPowerful: Her main color motif in both youkai and human form, signifying the position of power she holds in her hotel and the Battle Nexus.
* SeductiveSpider: Big Mama is a spider Yokai known as the Jorogumo. Like the mythological creature she takes the form of a beautiful woman to lure in unsuspecting victims to become fighters for her Battle Nexus. She is very flirty with [[spoiler:Splinter/Lou Jitsu]] even after the latter learned of her malevolent nature, and many other males throughout the show.
* SilverFox: Her status as a youkai makes it difficult to determine exactly how old she is, but it's noted within the show that she wears her age very well.
* TsuchigumoAndJorogumo: She's an attractive woman that turns into a GiantSpider youkai. Her backstory with [[spoiler:Lou Jitsu]] even borrows closely from classic jorōgumo tales of men being enticed by the youkai's human guise. However, her spider form's bulky, fur-covered design is more typical of the male tsuchigumo (or the even more monstrous ushi-oni).
* UncertainDoom: [[spoiler:In "Battle Nexus: New York", Foot Recruit destroys the Grand Nexus Hotel, but Big Mama's fate isn't shown; while Foot Recruit ''does'' tell her that she should probably run, the Hotel is destroyed and we don't see her clearly get away. "Rise" reveals that she survived the destruction of her hotel, but was horribly injured as a result and had to be hospitalized.]]
* VillainousCrush: Shown to have some feelings towards [[spoiler:Bullhop]] after her dance with the latter, and has a history with [[spoiler:Lou Jitsu]] as it turns out. [[spoiler:She and Lou used to actually be a couple...before she revealed her true form and kidnapped Lou to become a fighter in the Battle Nexus. [[AmicableExes She actually is still attracted to him when she meets him as Splinter, even moreso now that he's a mutant in fact.]] And in "Rise" when she hears that his life is in danger, she helps out the turtles.]]
* VoluntaryShapeshifting: She has a sort of mystical device her and her workers wear, which allow her to look human.
* WhiteHairBlackHeart: Has white hair but she's an AffablyEvil yokai.
* {{Youkai}}: She calls herself and the beings who work under her as such, and is modeled off (if not outright) a Jorōgumo.

[[folder:The Shredder]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shredder_1.png]]
[[caption-width-right:350:''"You are no match for The Shredder!"'']]
--> '''Voiced by:''' Creator/HoonLee
The true leader of the Foot Clan. A set of cursed demonic armor brought to malevolent life, it's as powerful as it is vicious.
----
* AdaptationalAbomination: Downplayed. The Shredder in other incarnations is generally human, but in this series is a demonic set of armor that devoured the wearer and their soul.
* AdaptationalBadass: In other incarnations, Shredder is merely very proficient at combat, albeit usually at a greater skill level than the Turtles. This incarnation, however, is [[ExaggeratedTrope literally]] a [[AdaptationalAbomination destructive demon]] [[spoiler:that the Turtles have ''significant'' difficulty battling in their first real fight against him, [[ImplacableMan often because he just gets back up after a heavy hit]]]]. In most incarnations, Splinter alone is a worthy adversary to the Shredder, but in this case [[spoiler: not even Splinter and the Turtles ''together'' (along with April and Draxum), even empowered with mystic weapons this time, are capable of holding him back for more than a few minutes and find it nearly impossible to actually hurt him. He's shown being able to level buildings with the sheer air pressure of his blows alone, let alone when they connect.]]
* AdaptationalHeroism: [[spoiler:Oroku Saki was actually a good man who only became the Shredder after making a deal with a demon so he could defend his village, and it's implied that this version is [[AndIMustScream trapped in his own body]], and leaves the heroes on peaceful terms after the Shredder is defeated.]]
* AdaptationalNonsapience: Shredder acts like a raging animal with no intelligence, though the legends imply that he wasn't always this way. [[spoiler:He regains his sapience at the end of "E-Turtle Sunshine of the Spotless Mind"]].
* AdaptationalSympathy: [[spoiler:Oroku Saki's reasons for becoming the Shredder vary across continuities, but is generally an identity he adopts to become [[TheDreaded feared]]. In ''Rise'', Oroku Saki became Shredder out of a desperate attempt to protect his Clan, only for his soul to be devoured by the armor.]]
* AncientEvil: He's been dormant for hundreds of years due to his armor being broken apart.
* AndIMustScream: [[spoiler:It's implied at the end of "Shreddy or Not" that the good man Oroku Saki still exists, but his will is buried under the evil armor, and is ultimately freed by the end of "Rise".]]
* AnimatedArmor: Is a demonic set of armor that gained life after consuming his wearer.
* ArchnemesisDad: In very technical terms. [[spoiler:The body he possessed and eventually consumed is that of Karai's father]].
* AttackAnimal: [[spoiler:Thanks to a mind control collar, he effectively became this to Big Mama, who restyled him as her Battle Nexus champion and main muscle. Then the Foot Recruit gets control of him in "Battle Nexus: New York"]].
* BadBoss: [[spoiler:In the series finale, once he reattains his sentience, he initially only shows [[MeanBoss mild annoyance]] at the antics of his three henchmen, but once Foot Lieutenant and Foot Brute get stuck under rubble, he tells Foot Recruit to abandon them.]]
* BigBad: [[spoiler:After spending much of the series as the GreaterScopeVillain, he steps into the role fulltime by the second season, but spends much of it as a mindless, raging brute. Upon regaining his sentience, he becomes the TrueFinalBoss of the series.]]
* CameBackWrong: [[spoiler:When he's fully brought back, he behaves more like a wild animal rather than someone you'd expect to be the leader of an evil ninja clan. Several characters make note of this, suspecting something went wrong during his resurrection. His physical form is also in flux, constantly phasing in and out of reality. It turns out to be due to missing his will, due to it being sealed away in another dimension. His sapience is restored in "E-Turtle Sunshine of the Spotless Mind" after his will is released from the Twilight Realm]].
* ClippedWingAngel: [[spoiler:He's still plenty powerful when he's brought back, but his mind has apparently regressed to a feral beast, and he constantly phases in and out of reality, keeping him from delivering the finishing blow to the turtles time and again.]]
* CompositeCharacter: He's a demonic entity and resembles the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] Demon Shredder's original Tengu form, but the Foot Clan serves under him, much like traditional incarnations, which the Demon Shredder notably lacked beyond his Mystics (who were acquired by the Foot Clan the Utrom Shredder set up later in the timeline), and sports the [[WesternAnimation/TeenageMutantNinjaTurtles1987 1987]] Shredder's purple colors. His larger size also gives him a resemblance to [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze Super Shredder]]. The series finale also reveals [[spoiler:his armor was created by an Utrom, giving him elements of Ch'rell.]]
* ContrastingSequelAntagonist: [[spoiler:Unlike Baron Draxum and Big Mama, both of whom had extensive resources, relied upon henchmen or allies, and were usually content to play the long game. The Shredder, by the final arc of the series, and the one where [[BigBad he takes center stage]], has very few henchmen to rely upon, is more likely to fight on the front lines, and is very proactive in getting to his plans.]]
* DealWithTheDevil: [[spoiler:He made a deal with a demon to transform him into the Shredder in order to defend the village. What he didn't know was that the process would corrupt his very soul.]]
* DramaPreservingHandicap: In his first appearance, [[spoiler: he's constantly phasing in and out of reality at random intervals, which is good news for the Turtles, since every encounter with him is an utter CurbStompBattle. The Shredder phasing out of reality in the middle of their first encounter was the only thing stopping him from slaughtering them all on the spot. [[FromBadToWorse Then he regains his sapience in "E-Turtle The Spotless Mind"]]]].
* TheDreaded: Just seeing the Foot Clan's sigil makes ''Splinter'' [[OOCIsSeriousBusiness get off of his butt]] to try to stop Shredder's armor from being completed. [[spoiler:As soon as the heroes realize that they've been fighting the Shredder in "Battle Nexus: New York", Splinter almost ''immediately'' commands everyone to retreat.]]
* EvilSoundsDeep: His roars and [[EvilLaugh chuckles]] have a noticeably bass-y reverb to them. [[spoiler:His actual speaking voice is actually slightly higher-pitched, but [[PowerEchoes still retains the reverb]]]].
* FlashStep: [[spoiler:He seems to have gained (or perhaps regained) the ability to do this some time before "Battle Nexus: New York"]].
* GreaterScopeVillain: He's the master of the Foot Clan, as well as an AncientEvil that even Master Splinter treats with the upmost seriousness, and stopping the Foot from reassembling his armor is a major plot point of the season.
* HateSink: [[spoiler:Upon regaining his sapience, the Shredder is firmly established to be a destructive murderer whose only concern is becoming invincible so he can continue his killing spree, he's [[BadBoss completely willing]] to throw away the lives of his henchmen (which significantly shakes the Foot Recruit's faith in him), and sees everyone as beneath him. Oroku Saki, however, [[AvertedTrope is not]] this trope, being an otherwise decent person who was pushed into a desperate situation, with the Shredder being a distinct entity.]]
* HumanoidAbomination: The Shredder has a humanoid shape, but is capable of inhumanly powerful feats such as [[spoiler:[[RazorWind cutting buildings]] with just the aftermath of swinging his arm, and shows some SizeShifting capabilities in the final battle, making him resemble a flaming EnergyBeing.]]
* ImplacableMan: [[spoiler:In "Many Unhappy Returns", no matter what the Turtles throw at him, they don't slow him down. It takes them discovering he's ticklish, can be blinded, and that he's attracted to sudden, bright flashes of light for them to gain any sort of advantage. When he returns in "Battle Nexus: New York", the combined efforts of ''eight'' fighters only serve to distract him slightly. It's only after getting cut in half by one large CombinationAttack from the entire Hamato Clan that he finally goes down for good]].
* InTheHood: [[spoiler:He wears a long hooded cloak while under Big Mama's control as the "Shadow Fiend"]].
* TheJuggernaut: This incarnation of Shredder is a powerhouse who raw power is unmatched and allows him to effortlessly overpower the turtles on several occasions. It takes ''everything'' and more for the heroes to finally defeat him in the finale.
* JumpScare: Any time ''anything'' related to his armor appears on screen in season 1, a sudden and brief flash of The Shredder's demonic face flashes on screen and gives a hoarse roar to indicate that Shredder is far more terrifying and dangerous than any other villain seen thus far. [[spoiler: Season 1 also closes on one that could very feasibly be Shredder ''actually roaring at the heroes.'']]
* KnightOfCerebus: The very first episode he's directly mentioned in is noticeably more serious, and rife with frightening, almost JumpScare level imagery showing the level of Shredder's atrocities, with even the villains being much more [[NoNonsenseNemesis direct]] than usual (barring a brief relapse from the Foot Lieutenant and Foot Brute). [[spoiler:His first real appearance in the series, while playing him a bit more for humor due to comedic weaknesses, shows him as a threat that is so outside of the Turtles' league that he very likely would have killed them if he wasn't [[DramaPreservingHandicap phasing in and out of reality]]. Once the Shredder's will is restored, he proceeds to cause the show's DarkestHour.]]
* MagicFromTechnology: A flashback in the second part of the season 2 finale strongly implies that [[spoiler: the Shredder's armour was created and given to Oroku Saki by an Utrom (misinterpreted as a demonic oni) centuries ago, and is therefore advanced alien technology]].
* ManBitesMan: He tries to use his razor sharp teeth to attack his opponents at multiple points, he still does this even after he [[spoiler:regains his intelligence]].
* MechanicalAbomination: The series finale heavily implies [[spoiler:he's a suit of armor made from alien technology, and his [[ShapeshifterWeapon shapeshifting]] abilities heavily involve transforming his body into metallic tools or weapons.]]
* MythologyGag: This isn't the first time Shredder's been portrayed as a demonic entity, with the [[LegacyCharacter original]] in the 2003 incarnation being as such, and the armor in this incarnation looks very similar to that of the Tengu Shredder's original form. He also has other numerous stylistic similarities to the incarnations from that series, such as his glowing pink eyes that evoke the [[RedEyesTakeWarning red eyes]] from the 2003 version, the three-pronged crest on his helmet resembles that series' Foot Clan sigil, and his voice is edited to [[PowerEchoes reverberate]] like that series' bearers of the identity.
** While the Shredder's steel claws are otherwise phased out of this continuity, [[spoiler:he briefly creates them a few times in the series finale in close range scuffles.]]
* NoNonsenseNemesis: [[spoiler:After regaining his sentience, he ''immediately'' decides to try and kill Karai in her weakened state due to her having defeated him before, and ignores anything that could distract him from becoming invincible.]]
* NotHimself: [[spoiler:He behaves more like a rabid beast than an evil warlord when he's brought back to life. Multiple characters make note of how this behavior isn't in line with the legends. It's revealed to be a result of his will being sealed in the Twilight Realm, which is released at the end of "E-Turtle Sunshine of the Spotless Mind".]]
* PullingThemselvesTogether: No mortal weapon can pierce his armour, although some ''mystic'' weapons can. It's not much better though, since pieces of Shredder's armour that crack or break off almost instantly reconnect themselves.
* RazorWind: [[spoiler:When fought in "Battle Nexus: New York", he takes a swing at Draxum that he just barely dodges. The shockwave from said swing cuts all of the surrounding buildings in half.]]
* RealAfterAll: Splinter thought that the Shredder's legend was just a story.
* RelatedInTheAdaptation: [[spoiler:This version of Oroku Saki is a distant ancestor of Splinter/Hamato Yoshi and the Turtles, as the Hamato clan was founded by his daughter Karai.]]
* SealedInsideAPersonShapedCan: Downplayed. [[spoiler:While his body can move, it lacks his will and is a wild animal. In "E-Turtle Sunshine of the Spotless Mind", once Karai is released, Shredder's will, sealed away in the Twilight Realm, returns to his body.]]
* ShapeshifterWeapon: [[spoiler:He can turn his body into a variety of tools or weapons, such as drills or his iconic steel claws.]]
* ShoutOut: [[spoiler:He turns into a large energy being resembling ''Anime/TengenToppaGurrenLagann'''s Granzeboma, and frequently turns his hands into drills.]]
* SmugSuper: [[spoiler:His true personality is a combination of this and an ArrogantKungFuGuy. He views everyone else, [[BadBoss even his own followers]], as completely beneath him, but considering just what it takes to put him down and his raw destructive power, he's got ''a lot'' to back up his mentality]].
* SpikesOfDoom: [[spoiler: After he gets his sanity back he displays the ability to summon a field of metallic spike from the ground as a means of taking out multiple opponents at once]].
* SuddenlyVoiced: [[spoiler:He finally speaks at the end of "E-Turtle Sunshine of the Spotless Mind", when he regains his sapience.]]
* UnskilledButStrong: [[spoiler:Whether he's a mindless animal or sapient, he shows very little finesse or strategic ability while fighting. This weakness is offset by his obscene strength (enough that he can cut buildings and destroy most of Big Mama's tower with just the ''air pressure'' of his blows) and durability, to the point ''eight'' people fighting against him in "Battle Nexus: New York", many of them being exceptional martial artists, are the ones at a disadvantage.]]
* VileVillainLaughableLackey: [[spoiler:Upon becoming sapient, most of the humor and levity comes from Foot Recruit, Foot Lieutenant, and Foot Brute's interactions with him, with the Shredder himself being a [[HateSink despicable]], no-nonsense monster.]]
* VillainousBreakdown: Implied. [[spoiler:After Casey betrays him and he loses his chance to consume Splinter's essence, his intent seems to shift to simply killing the Hamato Clan without taking Splinter's essence, to the point of turning into a [[OneWingedAngel much stronger form]] to overpower and demoralize them after they join their mystic powers together for one powerful attack. When the Hamato Clan regains the advantage through the help of the spirits of their ancestors, all he can do is shout the word "[[BigNo NO!]]"]]
* VocalDissonance: [[spoiler:When he regains the capacity for speech, his voice turns out to be fairly normal sounding despite it coming from a hulking, monstrous suit of armor]].
* TheVoiceless: [[spoiler: Coinciding with his mental regression into a mindless beast, he doesn't speak. All he does is roar, growl, and let out the occasional [[EvilLaugh evil chuckle]]. He finally speaks in the four part series finale.]]
* WasOnceAMan: [[spoiler:Oroku Saki was once a regular man until a demon corrupted his soul and transformed him into the Shredder.]]
* WeaksauceWeakness: [[spoiler:As it turns out, he's ticklish in the back of the knees. He's also left completely disoriented and open whenever he's blinded. Finally, he's single-mindedly attracted to and distracted by flashing bright lights. All three discovered weaknesses are used to successfully restrain him with Big Mama's collar. These weaknesses don't come up in any of his subsequent fights, however.]]

[[folder:The Foot Clan]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/riseoftmntfoot.jpg]]
-->'''Foot Brute Voiced by''': Creator/MauriceLaMarche (English), David Allende (Latin American Spanish)\\
'''Foot Lieutenant Voiced by''': Creator/RobPaulsen (English), Daniel Lacy (Latin American Spanish)\\

The Foot Clan are a group of evil ninjas bent on taking over New York City! They have the power of teleportation through hidden gateways and the ability to create and control Origami Ninjas.

The known members include a short man credited as "Lieutenant", a large man credited as "Brute", and later on a female recruit (who has a separate entry).
----
* AncientArtifact: They spend the first season scouring New York for powerful artifacts, including a power gauntlet. [[spoiler: It's eventually revealed that the artifacts in question are pieces of ''[[ArchEnemy The Shredder's armor.]]'']]
* AdaptationDeviation: While previous incarnations of the Foot Clan had dabbled with magic, this one is much more heavily tied to the supernatural, and are essentially a cult devoted to the Shredder.
* AmbiguouslyHuman: Despite the Foot Clan usually being human, the both the Lieutenant and the Brute are extremely odd looking, having purple skin and creepy facial features. Both Lieutenant and Brute have question marks on the human entry of their official bios. [[spoiler:It doesn't help that their master, The Shredder, is a demonic set of AnimatedArmor in this continuity.]]
* ArchEnemy: Seem to consider the Turtles as such (although the Turtles themselves don't seem to even be aware of it), due to them constantly having put a stop to their plans. They even [[spoiler:team up with Baron Draxum under the mutual assurance they'll defeat the Turtles together]].
* BaldOfEvil: Not a hair on either of their evil heads.
* BrainsAndBrawn: The Lieutenant is the brain to the Brute's brawn.
* BullyingADragon: [[spoiler: While they were in their rights following the rules of the organization, treating Baron Draxum in a demeaning manner as opposed to an equal partner was a big mistake on their part, especially after he used those same rules to usurp control of the Foot Clan from them. They do get one over Draxum in the end though, manipulating him into resurrecting the Shredder for them.]]
* CompositeCharacter: The organization appears to take after different versions of the Foot Clan across different incarnations; they're a ninja group as per usual, but the AmbiguouslyHuman nature of the main enforcers and cult-like nature are respectively similar to the Foot Mystics from the 2003 cartoon, and the Foot cult from Season 5 of the 2012 cartoon, [[spoiler:with the same goal as both; resurrection of the Shredder]].
* CoDragons: For the Shredder. The Lieutenant and Brute appear to be of equal standing with their only authority being over the Recruit and the Origami Ninjas. They later become Baron Draxum's when he usurps control of the clan.
* DragonWithAnAgenda: Despite Draxum forcing them to yield to his authority, they still plan to bring back the Shredder and successfully manipulate him into putting the armor on, reviving their master.
* EarlyInstallmentWeirdness: The Foot Lieutenant and Foot Brute's ability to create Origami Foot Soldiers is largely dropped midway through Season 1 in favor of flesh-and-blood soldiers, and they never do it in Season 2 (albeit largely due to [[OutOfFocus not showing up]] until the final episodes).
* EvilDuo: They're always causing trouble together.
* EvilIsPetty: In "Mystic Library", once they see the Turtles are at the titular location, decide to interfere with whatever they're doing for no other reason except revenge for frequently being defeated.
* EvilSoundsRaspy: The Foot Lieutenant speaks in a raspy whisper that sounds like the result of a lifetime gargling sharp pebbles.
* EyesAlwaysShut: The Brute has eyes, they're just not visible most of the time.
* FatAndSkinny: The Foot Brute is built like a monster truck, and is at least four times wider than the Lieutenant.
* GlassCannon: The Origami soldiers are strong enough to knock Raph clear across the room, but are about as durable as you'd expect for beings made out of paper.
* TheHeavy: [[spoiler:With the Shredder gone, the Foot Clan spend much of Season 1 moving heaven and earth to resurrect him.]]
* {{Irony}}:
** They are big fans of Lou Jitsu but they are unaware that he's actually the last living descendant of [[spoiler:their ancient enemies, the Hamato clan]].
** [[spoiler:The Foot Clan's descent into evil was inadvertently caused by Oroku Saki trying to prevent it from being wiped out. Now the Foot Clan is effectively a cult that worships the Shredder, who will wipe out humanity if left unchecked.]]
* HiddenAgendaVillain: They're looking for artifacts for an unspecified reason. "The Longest Fight" ends with them stealing some sort of sharp gauntlet (with the Turtles thinking they just tried to steal what they call a "puny ring"), and they attempt to steal a similar gauntlet in "Stuck on You". "Shadow of Evil" sets the record straight, [[spoiler:revealing that they're acquiring pieces of the Shredder's armor to resurrect him]].
* LogicalWeakness: Their Origami soldiers are naturally pretty fragile, and water easily destroys them, and also renders them unable to create more.
* ManipulativeBastard: [[spoiler:They offer Draxum the Shredder armor in exchange for his assistance in tracking down the pieces, conveniently omitting the fact that the armor would drain his life force to reanimate itself.]]
* MookMaker: The Lieutenant is adept at origami, which allows him to deploy several Soldiers at once.
* NoNameGiven: They're credited as the "Foot Lieutenant" and "Foot Brute", with no hint to their real names given.
* NotSoAboveItAll: The Lieutenant and Brute are fans of the Lou Jitsu movies, with the former, generally the smarter and more serious of the two, gushing about the films in "Hot Soup: The Game" alongside the Brute. "End Game" shows this extends to them being so awed by [[spoiler: Splinter, a transformed Lou Jitsu, clobbering their minions that they forget to dodge his attack.]]
* NotSoHarmlessVillain: They often banter with one another, frequently engage [[VillainsOutShopping in various mundane activities]] and will gush about Lou Jitsu but they are also fairly competent fighters in their own right and they successfully [[spoiler:manipulate Draxum into wearing the life draining Shredder armor so as to resurrect their demonic master]].
* PaperMaster: They can bring their Origami soldiers to life as this series' incarnation of the Foot Soldiers.
* PowerTattoo: They have an orange foot tattoo on their faces that appear to emit flames. It's apparently part of being elevated to full clan status and is received via getting ''kicked in the face'' by a high-ranking member of the clan.
* TheRival: The Foot Brute acts as this to Raphael in their battles and in the opening.
* ShooOutTheClowns: [[spoiler:Shredder leaves the Foot Lieutenant and Foot Brute for dead under rubble in the series finale, which both sidelines the humor in favor of focusing on the urgency of defeating the Shredder, and instigates the Foot Recruit's HeelFaceTurn.]]
* UncertainDoom: [[spoiler:After being buried under rubble in "Rise", the Foot Brute and Foot Lieutenant don't show up again.]]
* ZergRush: Their Origami Soldiers aren't very tough, but make up for it with sheer abundance.

[[folder:Foot Recruit]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tumblr_pn0ygx69nk1xh4d0to6_1280.png]]
-->'''Foot Recruit Voiced by:''' Creator/ZeldaWilliams (English), Pamela Cruz (Latin American Spanish)

A young woman who very desperately wants to become a full member of the Foot.
----
* AdaptationalVillainy: [[spoiler:Unlike previous iterations of Casey Jones, who's an ally of the Turtles from the start, this version is a fanatic follower of the Foot Clan and a recurring villain up until her HeelFaceTurn in the finale.]]
* BadassNormal: Usually fights unarmed against the superhumanly strong heroes, and without access to the supernatural powers of her senior officers.
* BladeOnAStick: She wields one in the finale, notable in that [[spoiler:the tip gets bent during her HeelFaceTurn, putting it into the shape of a [[FiveSecondForeshadowing hockey stick.]]]]
* BloodKnight: The Recruit's predilection towards violence is so intense that the Lieutenant and Brute actually [[EvenEvilHasStandards show some concern towards her]].
* BoyishShortHair: Her hair is cut very short, and there's very little that's feminine about her.
* CanonCharacterAllAlong: [[spoiler: "Rise" reveals that she's indeed this show's version of Casey Jones.]]
* ChildProdigy: She was apparently accepted into every clan she applied to as a child.
* ChildSoldier: She's apparently been training with the Foot since she was seven.
* TheComicallySerious: She reacts to every situation with the same bombastic intensity she always has, even if she's just doing something mundane like going on a coffee run for her bosses.
* CompositeCharacter: You would be forgiven in thinking that she was this series' version of Karai, being a DarkActionGirl that runs the Foot Clan when the Shredder isn't and has a love/hate relationship with the turtles, but the series finale reveals [[spoiler:that she's actually this series' incarnation of Casey Jones.]]
* DarkActionGirl: The Recruit is just as deadly as her two superiors, being just as capable of keeping up with the Turtles. [[spoiler:She becomes a more straightforward one after her HeelFaceTurn]].
* TheDragon: Despite being lower on the totem pole than the Lieutenant and Brute, she winds up becoming the Shredder's in the finale, before undergoing a HeelFaceTurn.
* DudeWheresMyRespect: She expresses frustration when a group of Foot initiates are promoted to full membership while she gets passed over, despite her being there longer than any of them.
* EvenEvilHasStandards: [[spoiler:She's completely unnerved by the Shredder's command to just abandon the Foot Brute and Foot Lieutenant in the rubble, which contributes to her HeelFaceTurn.]]
* EvilCounterpart:
** Similar to April in how she's a passionate tertiary member of a group of ninjas... Except evil. Splinter himself compares the two in "Always Be Brownies", albeit without explicitly naming April.
** She's also positioned as one to Mikey in her debut episode. Both are sensitive to criticism and hopeful to prove themselves to their teammates... but she lashes out ''far'' more intensely than Mikey.
* EvilGloating: Has a bad habit of standing still and laughing at her enemies [[ArrogantKungFuGuy whenever she's winning in a fight]], which just allows her opponents to turn the tables on her.
* {{Foreshadowing}}: Toward her [[CanonCharacterAllAlong true identity]]:
** In "Always Be Brownies", the Girl Scout organization she runs is called "Grandma CJ", and there's sports equipment in her room, [[spoiler:which hints that she's actually '''C'''asey '''J'''ones.]]
** In "Battle Nexus: New York", she fights [[EnemyMine alongside]] the Turtles against the Shadowfiend, prominently using April's baseball bat which she threw to her. [[spoiler:Baseball bats are one of Casey Jones' staple weapons, and the fact she fights with the Turtles is hinting at [[HeelFaceTurn her redemption]].]]
* GenderFlip: [[spoiler:She's the show's incarnation of Casey Jones.]]
* GirlScoutsAreEvil: In "Always be Brownies", she [[OffscreenMomentOfAwesome somehow]] ends up founding and running an organization analogous to the Girl Scouts with the intention of taking over the world through bake sales. The members of her organization, who are preteen girls at most, are all trained in ninjutsu, including bladed weapons.
* GivenNameReveal: In "Rise", she [[spoiler:quits the Foot Clan]] and reveals her name [[WhamLine in a rather dramatic fashion]]:
--> "The name's [[spoiler:Cassandra, ''[[CanonCharacterAllAlong Cassandra Jones]]''!]]"
* HeelFaceTurn: [[spoiler:After seeing the full extent of Shredder's cruelty, Foot Recruit decides to turn on him and join the good guys.]]
* HiddenDepths: "Always Be Brownies" has her running a successful Girl Scouts-esque organization, with the end of the episode suggesting that she also engages in sports, due to sports equipment being able to be spotted in her room. [[spoiler:The latter turns out to be [[{{Foreshadowing}} a hint]] that she's really Casey Jones.]]
* {{Irony}}: She angrily tells Big Mama in "Battle Nexus: New York" [[spoiler:that she enslaved her master, the Shredder. However, Shredder was so insane, she had to ''keep'' him under the same control to serve him in the long term.]]
* LargeHam: She spends a lot of her screentime gesturing dramatically while shouting.
-->'''The Recruit:''' (as she jumps off a building) '''"FOOT CLAAAAN!"'''
* NoIndoorVoice: There's rarely a moment where she isn't shouting.
* NoNameGiven: Is simply credited as "The Foot Recruit" in and out of universe, and eventually even that's shortened down. [[spoiler:It's revealed that her name is [[CanonCharacterAllAlong Casey Jones]]]].
* NotSoAboveItAll: Just like her bosses, the Recruit isn't above goofy behavior. During her fight with Raphael during "Insane in the Mama Train" she even gets locked in a prolonged "bring it on"-off and knocks his hand off course so he uses the train's transport system to jump to the wrong room with a mischievous smirk.
* NotSoHarmlessVillain: [[spoiler: Becomes a lot less funny and a lot more threatening once she gets control of The Shredder.]]

** [[spoiler:In "Battle Nexus: New York", she talks ''much'' more quietly to Big Mama after taking control of the Shredder and preventing her escape.]]
** [[spoiler:After Shredder abandons his Lieutenant and Brute, she's so shaken by it that she doesn't [[LargeHam speak bombastically]], even when trying to deny that she's having second thoughts about being the Shredder's General.

* UndyingLoyalty: The Recruit is fanatically loyal to the Lieutenant and Brute, blindly obeying any order they give her, until she clashes with them over controlling Shedder when she wants to set him free. [[spoiler:She ultimately turns on the Foot after witnessing The Shredder's cruelty even to them.]]

-->'''Voiced by:''' John Lydon (English), Miguel Ángel Ghigliazza (Latin American Spanish)
----
* AssimilationBackfire: This happens with him in ''Nothing But Truffle'' twice.
** Absorbing Todd's unique skill backfired on him and made him a nice and friendly person.
** And finally [[spoiler:absorbing the Were-Tree gives him a weakness to silver, even with the advantages]].
* AsLongAsItSoundsForeign: Meat Sweats talks with an accent that tends to fluctuate with each line. Typically, he sounds like an odd mix between Irish and German, but he also has a tendency to switch to British, French, and at one point even begins speaking like ''a pirate''.
* BizarreAlienLimbs: While not "alien," per se, those gloves he wears actually cover up the fact that he doesn't have any real hands anymore. When he removes them, his arm splits into several tentacles, which can be used to grab things like normal hands or [[EnergyAbsorption absorb the energy]] of whatever he touches (as well as taste it, apparently).
* CatchPhrase: "Unleash the flavor!"
* EnergyAbsorption: His main ability as a mutant. He can absorb the energy and special abilities of any mutant (and presumably human) he touches if he can hold them long enough.
* EvenEvilHasStandards: He's somewhat taken aback by the news that Splinter stole from his own sons, [[SubvertedTrope although]] judging by his tone it could've just been [[DeadpanSnarker his idea of a humorous comment]].
** He is also shown to be concerned about crashing a civilian when Splinter speeds his vehicle.
* GluttonousPig: Probably purposefully invoked. Doesn't help that he's also a chef.
* IAmAHumanitarian: Does not have a problem eating other mutants or porkchops for that matter.
* IJustWantToBeNormal: Or returned to his old appearance, at least. He doesn't seem to mind the benefits his mutant form offers (increased strength and the ability to absorbs others' powers), but in ''Cloak and Swaggart'' he is quite distressed when he loses his human appearance once again. He also seems to miss being the host of his cooking show.
* KnowWhenToFoldEm: After having his truck damaged and being forced to release his mutant catches, he throws Splinter off, deciding that no meal is worth this.
* MeanBrit: Zigzagged. He's a cannibalistic pig man who sometimes has a British accent, but his accent also fluctuates.
* NoCelebritiesWereHarmed: Seems to be based on Gordon Ramsey.
* PowerCopying: He can absorb the life of other mutants, and steal their powers.
* SupremeChef: He was a celebrity chef as a human, and characters who've eaten his cooking rave about how delicious it tastes. His poisoned pizza puffs in their title episode practically fall under ImpossiblyDeliciousFood considering everyone who gets a taste keeps attempting to eat them, ''even after being told that they're poisoned''.
* VillainousGlutton: Doubles as a FatBastard.

* GreaserDelinquents: He dresses the part with a leather jacket and slick pompadour.
* HiddenDepths: He has a love for cats. He even keeps taking care of his cat after she mutants and starts wanting to eat him, despite how dangerous the task of just feeding her can be.
* KickTheDog: His recruitment alongside the more overtly villainous Meat Sweats and Hypno-Potamus is prefaced by him trying to repossess the breathing tank of an old lady, showing that he can be just as dastardly as the other mutants Draxum conscripted.
* MoneyFetish: Gets very excited at the idea of a couple rich guys (Donnie and Mikey in disguise) buying his junk, to the point he almost sold his whole junkyard because they talked up their wealth so much.
* SlayingMantis: Not afraid to use his sickles.
* WingdingEyes: Has dollar signs for eyes at one point when he thinks Donnie and Mikey are a couple guys with cash to burn (literally).

* HostileAnimatronics: He's a former SuckECheeses mascot that turned into a murderous robot as a result of a mishap in his circuitry.
* NonStandardCharacterDesign: Barring his robotic implements, he looks more like a retro cartoon character, having PieEyes. Given that he's a cartoon mascot who has likely been around for a while (and who has had multiple iterations over the years), it's likely the retro design aspects are a holdover from previous iterations.
* PsychopathicManchild: Type B, having been an entertainer robot for kids, he's obsessed with parties and birthdays.

* ExoticEyeDesigns: His take the form of two red, scribble-like rectangles in yellow sclera.

* IronButtMonkey: Every episode with him in it features him getting stepped on at the very least. He somehow always manages to shrug his injuries off.
* NonMammalianHair: Maintains his poofy blond from his human days.
* NotSoHarmlessVillain: Seems to be becoming this as of ''Stuck On You'', albeit still a huge ButtMonkey. [[spoiler: Unfortunately, he loses the gauntlet to Baron Draxum at the end of ''Warren & Hypno, Sitting in a Tree''. So he's back to being harmless.]]
* PintSizedPowerHouse: He's this while wearing the enchanted gauntlet [[spoiler:that is a part of Shredder's armor]], which gives him SuperStrength and the ability to fire devastating energy blasts.

* SmallNameBigEgo: Considers himself the turtles' greatest nemesis, but they barely even notice him, let alone remember him.
* TheOnlyOneAllowedToDefeatYou: He won't allow anyone else to destroy the Turtles but him, which is why he saves them from Hypno-Potamus in his debut episode.
* UnknownRival: Not only to the turtles, but as he considers himself their greatest nemesis, he clashes with other villains who target them. April is the only person who takes him seriously (as his number one fangirl).

* AngryAngryHippos: A former stage magician turned massive humanoid hippopotamus and a talented criminal.
* BattleCry: Mezmer-ROO!
* CombatPragmatist: Some villains might take a hypnotized opponent and put them in a cell or death trap. Mezmer-Ron? Just as likely to cut the heads off his enemies while they're in an entranced state.
* EvenEvilHasLovedOnes: As a human, he was close to his pet hippo, Doug, and he wishes to resurrect him.
** Likewise, he genuinely cares for Warren, his best friend/roommate/[[AmbiguouslyGay it's complicated]].
* HypnoRay: Courtesy of his voice; it seems magical in nature and can even keep his targets suspended mid-air.
* MagicKnight: In addition to having the strength and murderous deadliness of a hippo, he still has all his magical abilities, some of which have been amplified by his mutation.
* SuperpowerLottery: His mutation made him big, strong, fast, and tough, which contrasts sharply with Warren Stone in the episode they both premiered in, whose mutation gave him none of those qualities.

* IntangibleMan: Becomes this after his mutation, which makes his name all the more fitting.

-->'''Voiced by:''' Ramone Hamilton (English), Pamela Cruz (Latin American Spanish)
* AdaptationNameChange:
** He's a young version of franchise-wide nemesis Baxter Stockman, and his surname is changed to "Stock''boy''" to play upon this.
** His trademark Mouser robots appear in "The Mutant Menace", but he refers to them as "microbots".
* AdaptationalNiceGuy: He’s arguably less villainous than he usually is. While Stockman was an evil scientist who performed on living organisms, Stockboy primarily wants to make money and a name for himself by making videos, which he does by putting people in danger, but is still far less actively evil than usual.
* AgeLift: He’s much younger than how he appears in most iterations, going from an adult man to a little boy.
* BadassNormal: Stockboy doesn’t have any powers, but is intellectually gifted for someone of his age. He has the Gumbus robot and his microbots to prove it!
* CanonCharacterAllAlong: He's initially presented as a new character, and just a DistressedDude whose misfortune brings the main characters to the plot, but the end of his debut episode reveals that he's this series' incarnation of TMNT antagonist Baxter Stockman.
* ChildProdigy: Despite being a little kid, his intelligence is enough to rival that of both Donnie and the Purple Dragons.
* CutLexLuthorACheck: Stockboy wants money, but only thinks to use his advanced robotics for a ScoobyDooHoax meant to ''get publicity for his online videos''.
* HisNameReallyIsBarkeep: He's a grocery store stock boy, makes videos under the name "[[XtremelyKoolLetterz Stockboi]]", and his family name is "Stockboy". April makes fun of him having such an on-the-nose name.
* MythologyGag: He has the hairstyle of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003]] version, serving as a quick hint to his identity in his debut.
* RobotMaster: Like most versions of Baxter Stockman, he's creates robots for his schemes, though his initial one is piloted.
* ShorterMeansSmarter: Justified due to being younger, although overall it's still a VagueAge whether he's a ChildProdigy or TeenGenius.
* TruerToTheText: Baxter Stockman is traditionally depicted as working with the Foot Clan, which started in the 1987 cartoon, with almost all later adaptations [[LostInImitation using this approach]] in some way. In ''Rise'', Baxter Stockboy has no ties to the Foot Clan at all, which, despite Stockboy being [[AgeLift younger]] and [[AdaptationalNiceGuy slightly less evil]], is actually a bit closer to the original [[ComicBook/TeenageMutantNinjaTurtlesMirage Mirage comics]], where Baxter was an independent antagonist who never worked with Shredder or the Foot Clan (and quite possibly never knew them to begin with).
* YoungerAndHipper: In previous incarnations, he's an adult. Here, he's a young boy. Hence why [[AdaptationNameChange he's called "Stockboy" instead of "Stockman"]].

-->'''Voiced by:''' Creator/TaniaGunadi (Kendra), Eugene Byrd (Jase), Creator/KyleMassey (Jeremy)
A club at April's school who moonlight as criminals.
----
* AdaptationDeviation: Probably among the most significantly reinvented aspects of the ''TMNT'' mythos for this series, even after Baxter Stockboy. Rather than being a New York gang who works under the Foot Clan, they're a tech club comprised primarily of three teenagers who commit cyber-crimes. The gang also have no relation to the Foot Clan, with the Purple Dragons generally being a subsidiary of that organization.
* AdaptationalIntelligence: Previous iterations of the Purple Dragons weren’t portrayed to be very smart, but in Rise, they’re quite talented with computers and other tech based activities/crimes.
* BigThinShortTrio: Jeremy is the “Big”, Jase is the “Thin”, and Kendra is the “Short”.
* TheCracker: They use their hacking skills for crimes, including robbing a bank. They also just steal things physically.
* EvilIsPetty: Their second appearance is them trying to kill Donnie's brothers with his own tech, simply in revenge for their first confrontation.
* IKnowYourTrueName: They call Donnie by his alias ''Othello Van Ryan'' in "The Purple Jacket". However, they call him by his real name in "The Purple Game", likely learning through hacking his gamer profile.
* InNameOnly: The Purple Dragons are generally a street gang subsidiary to the Foot Clan in other incarnations, whereas this one is a tech club with no relation to the Foot.
* NerdyBully: A tech club with a smug sense of superiority towards other tech geeks, including hanging them on their computers by the underwear. That's before they turn out to be outright criminals.
* WeUsedToBeFriends: Subverted. Kendra and April evidently knew each other since kindergarten. Although, it was unknown if they were friends before the start of the series.

[[folder:Kristoff Van Bradford]]
-->'''Voiced by:''' Creator/PeterStormare
An actor and martial artist who opened up several dojos across New York, replacing ones formerly owned by Lou Jitsu.
----
* AdaptationNameChange: He's based off Chris Bradford from the 2012 series, but this incarnation has a more European name due to being [[NoCelebritiesWereHarmed based off of]] Creator/JeanClaudeVanDamme.
* AmbiguouslyRelated: His top student bears a notable resemblance to him and is especially focused on pleasing him, suggesting they could be father and son.
* EvilCounterpart: While Splinter was mutated against his will, but makes the most out of his new form, Kristoff allowed himself to become a monster by combining with his komodo yokai for more strength.
* JerkAss: He and his students regularly go to the last remaining Lou Jitsu dojo in New York just to torment the students that can't even fight back.
* NoCelebritiesWereHarmed: He's pretty clearly a pastiche of Creator/JeanClaudeVanDamme.
* TeamMemberInTheAdaptation: Inverted; unlike his 2012 counterpart, he has no relation to the Foot Clan.

[[folder:"The Oni" '''(SPOILER CHARACTER)''']]
An ancient being who granted Oroku Saki's wish for power by turning him into the Shredder. It may also be the creature inside the Crying Titan, and thus the source of Empyrean and all Yokai's power.
----
* AbusivePrecursors: It's implied that it's part of an alien race who ended up creating yokai, but this one in particular created the Shredder's armor.
* AmbiguousSituation: Karai assumes it was an {{oni}}, but its resemblance to Krang suggests it may be of extraterrestrial origin. It's also possible it's the pilot of the Crying Titan, meaning it may be long dead.
* GreaterScopeVillain: It created the Shredder and possibly all {{yokai}}, but it's only seen in flashback. If it's the being in the Crying Titan, then it appears to have already died or gone dormant.
* JackassGenie: It gave Oroku Saki the power to protect the Foot Clan, but it also turned him into a power-hungry tyrant.
* LastEpisodeNewCharacter: It's only shown in the series finale.
* MythologyGag: Its appearance is clearly modelled after Krang, which brings to mind the 2003 cartoon version of the Shredder who was an alien that took over the identity. It also emits the same screeching sound as the 2012 cartoon incarnation of Krang. If it's also the pilot of the Crying Titan, then it references Krang's android body from the 1987 series being capable of growing in size.
* NoNameGiven: Karai doesn't identify it by any name.
* {{Oni}}: Karai describes it as "an oni", though [[CallAPegasusAHippogriff it doesn't bear much resemblance]] to the typical depiction, and she may be very mistaken to its true nature.
* WalkingSpoiler: Its existence reveals the true origin of the Shredder, and possibly all {{yokai}}.

-->'''Voiced by:''' Eric Bauza

A famous action movie star that the Turtles are a big fan of and whose films Splinter uses as training material. We later find out that there's more to him than meets the eye…
----
* AdaptationPersonalityChange: [[spoiler:Most previous incarnations of Hamato Yoshi were disciplined and peaceful men who were heavily devoted to tradition. Lou Jitsu, on the other hand, was a loud and bombastic movie star who completely blew off his clan's duties for fame and fortune.]]
* AdaptationalAttractiveness: To go with the AdaptationPersonalityChange above, [[spoiler:while most versions of Hamato Yoshi are distinguished but otherwise reserved middle-aged men, if not older, Lou Jitsu happily flaunted his good looks and sex appeal in his prime.]]
* AnimalMotifs: He has a phoenix as a main decorative motif on his jumpsuit symbolizing [[spoiler:his metaphorical death as Lou and his rebirth as Splinter.]]
* ADayInTheLimelight: "Goyles, Goyles, Goyles" focuses on [[spoiler:the day he became mutated into Splinter and took the turtles that would become his sons.]]
* BadassNormal: [[spoiler:He was a former Battle Nexus Champion and seemingly the only human to ever have won the Battle Nexus. He was so skilled that Baron Draxum, whose opinion of humans is low, decided to use his DNA for his mutant army. Given that he's really Hamato Yoshi, this shouldn't come as a surprise.]]
* BlaxploitationParody: His movies reek of an Asian spin on Blaxploitation and are heavily played for comedy. [[spoiler: The fact that he took a stage name based on a martial art instead of using his real name of "Hamato Yoshi" only amplifies the satirical angle.]]
* BrokenAce: A handsome, famous, not to mention genuinely skilled martial artist... [[spoiler:who was kidnapped and forced to be a gladiator by his own lover (who turned out to not even be a human at all), resigned himself to be a warrior alchemist's guinea pig, and was ''then'' turned into a rat-human hybrid for trying to save the innocent test subjects of said alchemist.]]
* CanonCharacterAllAlong: [[spoiler:"The Evil League of Mutants" heavily implies, and "Shadow of Evil" confirms, that he's this series' incarnation of Splinter. "Insane in the Mama Train" further reveals that Lou Jitsu is just a stage name and his actual name is indeed Hamato Yoshi.]]
* CatchPhrase: He shouts "Hot Soup!" in his films. It's so iconic that he even has a video game called "Hot Soup!"
* ChekhovsGunman: After he's introduced in "Origami Tsunami", get used to seeing his face since [[spoiler:"The Evil League of Mutants" reveals that he's not just an action film star...]]
* ChickMagnet: Lou Jitsu was known to be a ladies' man. A flashback in "Turtledega Nights: Rat Man" has a cat yokai swoon over him (and the same one swoons over him years later), [[spoiler:while "The Ancient Art of Ninja Hide and Seek" and "Many Unhappy Returns" reveals that he has history with Big Mama.]]
* CompositeCharacter: [[spoiler:Combined with SparedByTheAdaptation, but much like [[WesternAnimation/TeenageMutantNinjaTurtles1987 his 1987]] and [[WesternAnimation/TeenageMutantNinjaTurtles2012 2012 incarnations]], he's a still living Hamato Yoshi who mutates into Splinter, not a dead man whose pet becomes mutated and the Turtles' mentor.]]
* CoolShades: The sunglasses he always wore were gold and shiny.
* CutenessProximity: [[spoiler:"Goyles, Goyles, Goyles" had him ''coo'' over the baby turtles that would eventually become the "Mad Dogs", even giving pre-mutated Leo and Raph the names "Green" and "Green #2"]]
* DespairEventHorizon: [[spoiler:"Goyles, Goyles, Goyles" has him exhausted from fighting in the Battle Nexus, to the point that he's sworn off fighting.]]
* DelinquentHair: He rocked an epic pompadour.
* FriendToAllLivingThings: [[spoiler:"Goyles, Goyles, Goyles" had him befriend a rat when he was stuck meditating in his cell and he cooed over the turtles. Unfortunately, his rat friend bit him seconds before Lou was covered in mutagen...]]
* HeroOfAnotherStory: [[spoiler:Lou had an interesting life; aside from being a famous movie star, he's also a former Battle Nexus Champion and has history with Big Mama too!]]
* ImprobableWeaponUser: He was known for this, with Splinter trying to train his sons with movies involving ladders and fish in "The Evil League of Mutants". [[spoiler: Baron Draxum actually recognized this fighting style from the turtles, making him realize that Lou was still out there.]]
* InterspeciesRomance: He was a ladies' man both in the human and Youkai realms. A flashback shows him making a cat mutant swoon with a flirtatious wink, [[spoiler:and it's implied in "The Ancient Art of Ninja Hide and Seek" that he had a romantic history with Big Mama, then confirmed in "Many Unhappy Returns". Granted, he wasn't aware that Big Mama was a Youkai at the time before she revealed her true form, [[FailedASpotCheck despite the really obvious signs]].]]
* LadykillerInLove: [[spoiler:He genuinely fell in love with Big Mama and was planning to propose to her. Unfortunately, that pretty much flew out the window after she revealed her true form to him and kidnapped him to become a Battle Nexus combatant. As shown by the way he looks at the picture of him and Big Mama when he retrieves it he likely still can't help but hold a candle for her.]]
* MrFanservice: He's a ''very'' handsome man. The show also likes [[FemaleGaze emphasizing his chest and backside]].
* MundaneUtility: Downplayed. [[spoiler:Hamato Yoshi used his impressive martial arts skills to become a movie star [[StageName called]] Lou Jitsu rather than commit to his duties to stopping the Foot Clan.]]
* NeverFoundTheBody: Draxum mentions that the last he saw of Lou was when his lab was destroyed and he took the turtles with him. [[spoiler:Because Lou Jitsu would eventually become Splinter.]]
* NoCelebritiesWereHarmed: His name, along with him being a movie star martial artist known for improvisation is most likely based on Jackie Chan with a little Bruce Lee on the side.
* PunnyName: It's a play on either "Jiu Jitsu", a type of martial art or "Ninjutsu" which is the fighting style of ninjas. [[spoiler:The latter is probably forshadowing that Lou is Splinter.]]
* RageBreakingPoint: [[spoiler:"Goyles, Goyles, Goyles" has him absolutely exhausted from the Battle Nexus fights and swearing off fighting...until he learns that Draxum wants to mutate the baby turtles for his army. Cue ''pissed off rampage''.]]
* ShowWithinAShow: He's the star of various action films that the turtles watch and Splinter uses as teaching material. "Hot Soup: The Game" even shows he had his own video game based on him. [[spoiler:Of course it makes sense Splinter would be so attached to these films and video game since he ''was'' Lou Jitsu.]]
* SignificantDoubleCasting: He has the same voice actor as Splinter. [[spoiler:Because they're one and the same.]]
* SparedByTheAdaptation: [[spoiler:Combined with CompositeCharacter, but much like his 1987 and 2012 incarnations, he's a still living Hamato Yoshi who mutates into Splinter, not a dead man.]]
* StageName: [[spoiler:Lou is this to Hamato Yoshi/Splinter.]]
* TwoAliasesOneCharacter: [[spoiler:He's Splinter before he was mutated into a rat man by Baron Draxum.]]
* WalkingSpoiler: It's safe to describe him as an action star that the Turtles are fans of. Anything past ''The Evil League of Mutants'' and ''Shadow of Evil'' however...
