->''"Only way I bust a fang is if I'm chewing on someone's leg."''

An alpha dog who is a lieutenant to the Foot Clan. He used to be the heir of one of New York's wealthiest families, until he journeyed to train in many martial arts, with his training in ninjutsu, and became a famous martial artist by owning a chain of dojos across America. Eventually he and his dojo chain joined the services of the Shredder and the Foot Clan after Oroku Saki refounded the clan. Becomes a dog-like mutant Dogpound and and later a bony werewolf-like super mutant Rahzar. He also had a television cartoon prior to meeting the Shredder, which is the cartoon gag for the fourth season.

* AdaptationalBadass: In ''The Secret of the Ooze'', Rahzar only relied on brute strength. Here, he's also a skilled ninja.
* AdaptationalIntelligence: The original Rahzar had the mentality of an infant, whereas here he's fully articulate and capable of speech.
* AdaptationalVillainy: In regards to becoming Rahzar. The original Rahzar was a [[Film/TeenageMutantNinjaTurtlesIITheSecretOfTheOoze stupid infant]], and here Rahzar is an unrepentant and pretty malicious loyalist to the Shredder.
* ADayInTheLimelight: "Mikey Gets Shellacne" partly revolves around his desire to be human again and his subsequent mutation into Rahzar. Later, he gets some focus in "The Forgotten Swordsman" in which [[spoiler: he is brought BackFromTheDead and considers leaving Shredder's Foot Clan.]]
* AlasPoorVillain: [[spoiler:Considering he died a monster when he always wanted to be human again, struggling helplessly as Leatherhead drowned him; only to be revived as an undead puppet for Kavaxas and suffering a final fate of falling into the Netherworld, it's easy to feel sorry for him.]]
* ArchEnemy: To Michelangelo, due to the events of "New Friend, Old Enemy". He barely returns the feeling, though, viewing Michelangelo as just another nuisance. Despite this, Mikey still evidently considers him cool, if the trip into Mikey's mind and the resurfacing of his cartoon show in the fourth season is any indication.
* ArrogantKungFuGuy: He has shades of it, especially as Dogpound.
* BackForTheDead: [[spoiler:He's brought back to life in the fifth season after he's anticlimactically killed off near the end of the fourth season. He lasts two episodes, and then dies anticlimactically ''again'']].
* BackFromTheDead: [[spoiler:Rahzar is drowned by Leatherhead in "Requiem", but he's revived by Kavaxas in "The Forgotten Swordsman" to assist the demodragon and Tiger Claw in applying this trope to Shredder as well.]]
* BadassNormal: Bradford was able to hold his own against the Turtles, usually being able to fight two at once.
* BadBoss: Consider who he works for, and this is a given; He is at one point seen kicking one of his own men while they're down when he's annoyed, and regularly belittles Baxter Stockman, sometimes alongside Montes. [[TheDogBitesBack The latter didn't work out for him.]]
* BarehandedBladeBlock: He can do this with just his ''fingers''.
* BeardOfEvil: As a human, though Dogpound still has his mustache. Rahzar has a flap of fur that almost gives the impression of a Reaper's hood due to how thin he is.
* BrokenPedestal: Mikey looked up to and [[HeroWorshipper worshipped]] him, but the discovery that Bradford is one of Shredder's men and was just using him to try to track down Splinter completely ''shatters'' that.
* TheBrute: Big, bad, and brutish. He's far from DumbMuscle though. He's also physically the tallest member of the Foot Clan, about a head and a half taller than his master [[spoiler: until Shredder's mutation]].
* CameBackWrong: Though it doesn't seem that way at first, [[spoiler: it is revealed in "End Times" that Rahzar, like Shredder, was also resurrected to serve as Kavaxas' undead puppet, which is proven when Rahzar assists the zombie Shredder in attacking Tiger Claw and destroying the Seal of the Ancients.]]
* CanonCharacterAllAlong: In the second season, he became the character Rahzar.
* CoDragons: With Xever Montes to Shredder, at least until Karai enters the scene. And notably this is after Bradford and Montes have fallen out of favor with Shredder.
* CoolHelmet: He has a Shredder-esque helmet, but he rarely wore it as a human.
* CruelAndUnusualDeath: [[spoiler:Being drowned by being dragged to the depths of the ocean is one Hell of a way to go.]]
* DeadpanSnarker: Sometimes.
* DeathByAdaptation: [[spoiler:In the original live-action films, Rahzar's fate was being reverted back into an ordinary wolf. Here, he first gets drowned by Leatherhead, then he gets brought back to life by Kavaxis only to suffer a DisneyVillainDeath two episodes later]].
* DecompositeCharacter: He has some characteristics of Hun from [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2003 series]], despite this show having its own version of Hun. He is a big, strong martial artist, the Shredder's Caucasian [[UndyingLoyalty very loyal henchman]], who happens to connect with the Turtles online (Hun unknowingly played an online game with the Turtles, while Bradford became friends with Mike online) and eventually mutates into this show's iteration of a famous mutant character from the franchise (Hun became Slash in ''WesternAnimation/TurtlesForever'', while Bradford became Rahzar).
* DemBones: His transformation into Rahzar.
* DemotedToDragon: In the second season, Karai becomes the new second-in-command and is left in charge, lowering his status to become TheBrute with Fishface. He later answers to Tiger Claw, but in contrast with his relationship with Karai, he forges a mutual respect with the new Dragon. His competence, loyalty and lengthy history with the Shredder also gives him a high position in the Foot Clan's hierarchy, and he mentions in season three that he's in charge whenever Tiger Claw isn't around.
* DisneyVillainDeath: [[spoiler:He's kicked off a cliff into a chasm leading straight into the Netherworld, where he's never seen again.]]
* TheDragon: He's the Shredder's Dragon in the second half of the first season, being his most trusted servant and the field leader, though he eventually loses this position to first Karai, then Tiger Claw.
* DroppedABridgeOnHim: DoubleSubversion. [[spoiler:Despite being MadeOfIron, he's drowned very easily by Leatherhead towards the end of the fourth season. He's brought back to life in the fifth season...only to get kicked into a chasm two episodes later, where he fell to his death with absolutely no buildup whatsoever]].
* DyingAsYourself: [[spoiler:Averted. His final death is when he's been forcibly taken over by Kavaxas, and he falls into the Netherworld fighting Tiger Claw.]]
* EmpoweredBadassNormal: He was already a competent martial artist as a human. He became even more dangerous ss Dogpound and Rahzar.
* EstablishingCharacterMoment: His BadBoss tendencies and rivalry with Montes are demonstrated within his introduction.
* EvilCannotComprehendGood: He describes Splinter's [[ThouShaltNotKill unwillingness to kill]] as "not having the stomach to finish the fight".
* EvilCounterpart:
** To Michelangelo, as he becomes a major ButtMonkey of the team (though Mikey embraces it).
** He was also this to Leonardo in season one, being TheLeader on the field.
* EvilSoundsDeep: As Dogpound and Rahzar.
* EvilVirtues: Bradford has a few of these traits, like his loyalty to the Shredder, his sense of honor in regards to his losses, and his valor in not giving up.
* FaceHeelTurn: Whenever he joined the Foot Clan. Before the start of the series, he had his own TV show centered around fighting crime.
* FalseFriend: When Michelangelo attempts to befriend him, he goes with it and uses the connection to attempt to learn more about the Turtles.
* {{Foil}}: Prefers a more pragmatic approach and is rather famous, while his partner is a street rat who likes to take a much more violent and sadistic approach. His attacks are also much more brute force-based.
* ForcedTransformation: He hates his mutation into Dogpound. Subverted when he mutates into Rahzar. Even then, he still would like to be human again.
* GeniusBruiser: Can be quite the ManipulativeBastard when he needs to be. Best shown when he manipulated Mikey.
* GlassCannon: Rahzar can hit fast and hard, but he can be easily taken out, likely due to his extremely lean frame. [[spoiler: He's helpless when grabbed by the much larger Leatherhead and can only flail helplessly as he's drowned in the river.]]
* HesBack: A villainous example when he becomes Rahzar in "Mikey Gets Shellacne".
-->'''Rahzar''': I feel the mutagen coursing though me. I'm faster, stronger, more powerful than ever. I feel like a ninja again.
* HelmetsAreHardlyHeroic: Or villainous, in that case. Back when he was human, he used to wear a Shredder-esque helmet in his first appearance. After revealing himself to Mikey, he never wears that helmet again, even while he's in civilian clothes and his ninja outfit.
* IJustWantToBeNormal: Wants to turn back into a human in "Mikey Gets Shell Acne", but changes his mind upon his second mutation into Rahzar. "The Lonely Mutation of Baxter Stockman" later shows that while he's comfortable as Rahzar, he'd still prefer to be human again.
* ImAHumanitarian: Implied in "City At War", where he suggests eating Karai and Shinigami after kidnapping them.
* ItsAllAboutMe: Shown in "The Lonely Mutation of Baxter Stockman" when he tells the Foot Bots to retrieve the Retro-Mutagen since it belongs to him, highlighting how self-centered and egotistical he is. Xever's "rich boy" remark during their debut and his status as a martial arts celebrity only help further this portrayal.
* {{Jerkass}}: Oh, so very much. He's a bad boss to the human foot soldiers and looks down on anyone not in his social class be it his street thug partner in crime Xever, subordinate Baxter Stockman, or his mutant archenemies the Turtles.
* KickThemWhileTheyAreDown: Does this to a defeated Foot Ninja.
* KnightOfCerebus: A minor example in that after his mutation into Rahzar, he's not played for laughs nearly as much as Fishface or Stockman.
* LeanAndMean: His Rahzar transformation causes him to become much skinnier.
* LightningBruiser: He was fairly quick as a human, but lost this aspect when he became Dogpound, becoming more of a MightyGlacier, a fact he complains about in "Mikey Gets Shellacne". He stops complaining when he mutates into the far more quick and powerful Rahzar, regaining this trait.
* LogicalWeakness: He can survive an absurd amount of punishment, but [[spoiler:he still needs to ''breathe''. Thus, Leatherhead dragging him underwater kills him just like it would anything else.]]
* MadeOfIron: As Rahzar, he survives numerous things that would normally get someone killed, including electrocution (to be fair, Fishface and Baxter (while still human, no less) also survives this), getting an explosive hockey puck stuck on his mouth and even '''''being ran over by a subway train'''''. [[spoiler: Being drowned by Leatherhead finally does him in, however.]]
* ManipulativeBastard: Poor Mikey.
* McNinja: When he was human, Bradford was a Caucasian American male trained in ninjitsu by the Shredder and tasked both in training recruits for the Foot Clan and eliminating the Hamato Clan.
* MightyGlacier: As Dogpound. His greater size makes him MUCH stronger, but also too slow to dodge and his fights tended to have him mostly standing still. By the second season he's grown to detest this and welcomes the second mutation into Rahzar.
* NiceCharacterMeanActor: InUniverse: He played a hero in his movies and cartoon show, but is really a bad guy.
* NiceJobFixingItVillain: Not only does his attempted TakingYouWithMe in "The Gauntlet" disarm the Mutagen Bomb, it covers him and Xever Montes in Mutagen, mutating them into a dog man and a fish man. It gets zigzagged though, since his mutant dog form has much more physical strength, along with increased sense of sound and smell at the cost of losing some of his speed and most of his stealth as a human ninja.
** That said, the sight of him and Montes getting mutated did distract the Shredder long enough for the Turtles to get away from the Shredder as he about to kill them.
* NinjaPirateZombieRobot: Ninja werewolf zombie mutant as Rahzar.
* NoCelebritiesWereHarmed: His look is based on Creator/ChuckNorris. The {{Foreshadowing}} cartoon in season four shows that his cartoons were send-ups to Norris' old shows, as well as an ad for his "kung fu khakis" (a play on Chuck Norris' own "Action Jeans") seen on the back of a magazine April is reading in his debut episode. He also shares his name with a martial artist who wrote the ''Young Samurai'' books.
* NotSoAboveItAll: He actually ''likes'' his cheesy old cartoon, fondly remembering voice recording sessions and even keeps up with fan sites about it.
* [[NumberTwo Number Three]]: He's third in command of the Foot Clan, mentioning that he's in charge whenever Shredder and Tiger Claw aren't around.
* OutOfFocus: He has a lesser role in the second and third seasons, even after his mutation into Rahzar. On occasion he has a starring role, but he's not nearly as prominent as he was in the first season. This is thanks to a combination of losing his title as TheDragon and the Foot Clan swelling in ranks. Returns to focus in a different manner in the fourth season; Mikey is still a fan of Bradford and manages to dig up an old cartoon of him from the 80's while on board the Fugitoid's ship (this same episode which shows this adaptation's debut also saw a hologram of all three of Bradford's forms (his human form, Dogpound, and Rahzar), be used, and they're serving Mikey). Bradford/Rahzar in the flesh doesn't physically appear in the season until the end of the "Turtles in Space" arc, and he and the rest of the Foot Clan are back in the enemy role for the "City at War" arc.
* PragmaticVillainy: While he does want to kill Michelangelo in "New Friend, Old Enemy", he says that he can't because Michelangelo is bait and will lead them right to the Turtles' lair. Later agrees to work together with the Turtles to escape Stockman's maze and ceases hostilities when its clear that both sides are too tired to keep going for the day.
* PrimalStance: After becoming Rahzar, he's often seen crouching or slouching.
* ProgressivelyPrettier: Inverted to nightmarish and freaky degrees. When Chris becomes Dogpound, he has bone covering parts of his body, and asymmetrical arms. And when he becomes Rahzar, he becomes symmetrical, but also has an emaciated apparently-undead appearance with [[GlowingEyelightsOfUndeath glowing eyes and exposed bones]].
* PunnyName: Mikey names him "Dogpound" as the first battle after his mutation has the Turtles "pounded by a dog" and Rahzar as a "razor-faced dog".
* RedAndBlackAndEvilAllOver: His original costume invoked it. Now his pants and eyes do.
* RedEyesTakeWarning: As Dogpound.
* RedOniBlueOni: The red to Montes's blue.
* TheRival: To Fishface. It's died down since Tiger Claw became Shredder's new lieutenant, but they're still far from fond of each other.
* SavageWolf: He becomes far more wolf-like after his second mutation and sees being unwilling to kill as "not having the stomach to finish the fight" while also being completely loyal to the [[HateSink monster]] that is the Shredder.
* SleevesAreForWimps: As Bradford.
* SpikesOfVillainy: His Foot uniform had spiky pauldrons. He also has spikes on his body as Dogpound and Rahzar.
* TheRightHandOfDoom: Dogpound's left arm is grossly oversized. His right hand, meanwhile, seems to be completely covered in bone.
** Averted as Rahzar, which balances him out.
* TakingYouWithMe: Says this word-for-word to the Turtles before breaking open the Kraang's mutagen bomb. All it does is end up mutating both himself and Montes.
* TeethClenchedTeamwork: Even before their mutations, he and Xever Montes hated each other and only worked together because of Shredder's orders.
* ThisIsGonnaSuck: When Shredder discovers the Kabuto was stolen right under his nose, Rahzar nearly breaks down in tears apologizing to his master, dreading the inevitable maiming. However, Shredder lets him off easy, having more important things on his mind.
* TookALevelInBadass:
** After being mutated, he gains invulnerability to the point where Leo slashes him with his katanas, and he [[BarehandedBladeBlock catches them]], and strength enough to pick up a car. Not that this stops the Turtles from defeating him.
** Takes another when he falls into a vat of mutagen, mutating again into Rahzar. Though he loses some of his brute strength, his speed and agility greatly increase.
* UnderestimatingBadassery: Though he already respects Splinter, he claims he doesn't have the stomach to kill his enemies. Little does he know that Splinter is currently carving through their troops like butter and outright killing them in the process. He learns to be much more wary of the old master after this.
* UndyingLoyalty: He is the only member of Shredder's inner circle who is utterly loyal to his master, as Fishface is in it for the thrills, Bebop, Rocksteady, and Stockman were all pressed into service, Tiger Claw originally never intended to stay with the Foot Clan, and Karai pulls a HeelFaceTurn. It waivers a bit when Tatsu offers him a place in his new Foot Clan, but ultimately Rahzar decides to remain loyal to the Shredder, and Rahzar's the ONLY member of the Foot Clan to remain loyal to Shredder [[spoiler:and Kavaxas after Shredder is shown to have CameBackWrong and Kavaxas starts the apocalypse, with Rahzar/Bradford becoming responsible for Tiger Claw losing the Seal of the Ancients and forcing Tiger Claw to fight and kill him, again.]]
* VillainDecay: He gradually became less of a threat over the course of the first season, but it was reverted upon his mutation into Rahzar, whereupon he becomes a competent threat again. It happens again, as he can often be taken down quickly, but he's not as laughable as he was during the final hours of his tenure as Dogpound.
* VillainWithGoodPublicity: He's a martial arts superstar with a chain of dojos across the country, but he's secretly Shredder's star pupil.
* VillainousFriendship:
** Type 3 with the Shredder, he's loyal and devoted to him, but the Shredder cares not for Bradford. Nevertheless, Shredder usually treats him with more respect than most of his other lieutenants due to his loyalty.
** He develops one with Tiger Claw in "The Legend of the Kuro Kabuto", showing respect for their skills and a mutual dislike of Fishface. Tiger Claw later goes through the trouble of [[spoiler: having his corpse recovered from the bottom of the river and has Kavaxas bring him back to life.]]
** He's old friends with Tatsu, and is the only character the ninja master treats with respect during "The Forgotten Swordsman".
* VillainsOutShopping: In "The Super Shredder", he's shown watching an old cartoon he starred in, ''Chris Bradford's 2 Ruff Krew'', and even eating popcorn, an activity he mentions often indulging in. When Stockman informs him that Shredder wants him during the show, he's not happy:
-->'''Rahzar''': Awww, right at the good part!
* VirtueIsWeakness: In "Showdown", he deems Splinter weak, remarking that Splinter may be Shredder's equal, but "doesn't have the stomach to finish the fight." He's proven wrong; just because Splinter [[ThouShaltNotKill prefers not to kill his enemies]] doesn't mean he won't if there's no other choice.
* WasOnceAMan: After becoming Dogpound.
* WolverineClaws: His nails merge with his fingers to create natural claws as Rahzar.
* WolvesAlwaysHowlAtTheMoon: In "The Invasion", he first appears howling at the moon to get the attention of the rest of the Foot Clan.
* WorthyOpponent:
** Even though he deems him weak for not willing to kill, Bradford holds a lot of respect for Splinter, acknowledging him to be just as strong as his master. He ends up getting proven wrong and stops laughing at this, as the scene has his narration playing over a montage of Splinter entering the Foot Clan's lair and ''very'' clearly slaughtering several Foot soldiers, proving he really will kill his enemy.
** Mikey, for a while, does consider Bradford/Rahzar this to him by virtue of still being a big fan of his, though Rahzar does not return this.
** Despite being nominally against mutants and Shredder's inner circle, Tatsu respects Rahzar enough to offer him a place in his new Foot Clan. Rahzar refuses.

[[caption-width-right:150:[-Fishface-] ]]

->''"Mostly I like having a job where I get to crack skulls every day."''

An thug who shares a complete knowledge of criminal street routes with the Foot. He used to be a Brazilian street bandit, but got caught one night stealing a briefcase full of money that happened to belong to the Shredder, and luckily for him, the Shredder bailed him out of prison, impressed enough with skills to take him as a subordinate. He becomes a mutant snakehead fish.

* AfroAsskicker: He was this while being a human.
* AppropriatedAppellation: Averted, "Meet Mondo Gecko" reveals he takes "Fishface" as an insult.
* ArchEnemy: He seems to be Raphael's, since when the Turtles and the Foot Clan fight, they usually fight each other.
* ArtificialLimbs: The reason why Stockman was taken by the Foot Clan is because the Shredder needs him to give Fishface both artificial legs and what appears to be a scuba tank that pumps water into Fishface's gills.
* AttackTheTail: Splinter beats him in "Showdown, Part 2" by tricking him into biting his own tail.
* AxCrazy: The most obvious case out of Shredder's henchmen.
* BadassAbnormal: As Fishface, once he got his robotic legs, he started to fight all four them, and win.
* BadassBiker: He drives a fearsome-looking motorcycle in "Pulverizer Returns!" and "Vengeance Is Mine".
* BadassNormal: Montes was still able to hold his own against the Turtles.
* BadBoss: One of the few things he shares in common with his partner is his disregard for his henchmen (to the point when given the role to lead the mission by Shredder, he was willing to let Bradford die, and ''admitted'' this to his face) and Stockman. As with Bradford, [[TheDogBitesBack he never anticipated the possibility that Stockman would go for revenge]].
* {{BFS}}: In "The Manhattan Project" onward, Montes is sometimes seen wielding a balisword. (A giant butterfly/balisong knife)
* BlessedWithSuck: As a fish, he needs water to breath and has no legs.
* CardCarryingVillain: He makes no attempts to hide how little he cares for others or how dangerous he is.
* CanonForeigner: He was created for the series.
* TheCasanova: Implied by his yearnings for a lover every now and then.
* CoDragons: With Bradford to [[BigBad the Shredder]], at least until Karai enters the picture. Notably this is also after Montes and Bradford have fallen out of favor with the Shredder.
* CruelAndUnusualDeath: [[spoiler: Averted. Raph tears off his apparatus and leaves him on land to seemingly suffocate to death, but he turns up in the fifth season.]]
* CursedWithAwesome: He can inject venom into his opponents by biting them.
* DanceBattler: He uses capoeira. And surprisingly, it sticks after he gets new legs in his mutated form.
* ADayInTheLimelight: Fishface gets to be the main antagonist of "Meet Mondo Gecko", hosting an underground race for the Foot Clan and other villainous mutants on a clan-wide day off.
* DeadpanSnarker: Sometimes.
* DecompositeCharacter: He is Rahzar's partner, a role usually given to Tokka, who is given a completely different role in this continuity unrelated to Shredder or the Foot Clan.
* DemotedToExtra: He has an incredibly minor role in the second season, not even speaking in some of his ''five'' appearances. He gets a ''slightly'' larger role in the third season, but he's still nowhere near as prominent as he was in the first season.
* DualWielding: Sometimes with switchblades.
* EmpoweredBadassNormal: As Fishface.
* EvenEvilHasStandards: In "End Times", he decides that [[spoiler: things have gotten ''way'' too weird for him to handle and leaves the Foot Clan.]]
* EvilCounterpart: He possesses a preference for violence as well as a somewhat bad temper, much like Raphael, the character he usually tends to fight, and thus could be considered the logical extension of his personality if he were raised by someone like the Shredder. These similarities are [[NotSoDifferentRemark called upon]] in "Baxter's Gambit", where a discussion as they're [[EnemyMine working together]] leads the two to conclude that they are "of a kind".
* {{Expy}}: Of Hun from the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]] via having connections to street gangs, specifically the Purple Dragons. The only difference is Hun is the leader of the Purple Dragons while Montes is merely an associate. There's also the fact that Montes and Bradford were both mutated into animals. The animal mutation would also make Montes and Bradford expies of Bebop and Rocksteady or, since Dogpound became Rahzar, Fishface becomes an expy of Tokka by default.
* ExtremityExtremist: He attacks mostly with his legs.
* FishPeople: He becomes a mutant snakehead fish after getting doused in Mutagen.
* {{Foil}}: Prefers violent behavior and he's just a street rat, rather than his partner, the famous and pragmatic Chris Bradford. His fighting style is also much more fast-paced and quick.
** He's mainly seen as one to Raphael, due to both loving violence, but Raph knowing restraint and control with it.
* ForgottenPhlebotinum: Fishface's ability to poison people/inject venom by biting them was only shown in "The Pulverizer" and has never been used since then.
* TheFriendNobodyLikes: Nobody in the Foot Clan really likes him.
* FreudianExcuse: Downplayed. In "Baxter's Gambit", he talks about his life as a street rat and how he had to become a thief in order to survive in the world, but he himself makes it abundantly clear that he ''likes'' to do terrible things.
* {{Hypocrite}}: Xever tells Stockman-Fly that he looks nasty, despite his appearance as a mutant snakehead fish being slightly hideous as well.
** He also tells Anton Zeck that he talks too much (though he immediately lampshades it by adding "[[HypocriticalHumor And that says a lot, coming from me!]]").
* IHaveManyNames: Downplayed, as he's referred to by his human name by the Foot Clan, and the name Mikey gave him by the Turtles.
* IJustWantToBeNormal: Downplayed, with his robotic legs and breathing apparatus, Montes is comfortable with his mutation, at least moreso than Bradford is, but when he thinks Stockman can change them back, he jumps on the chance.
* InformedSpecies: Despite being classified as a mutant snakehead, he bears absolutely ''no'' resemblance to one.
* {{Jerkass}}: Mikey explicitly calls him a jerk when he's in the process of [[KickTheDog kicking the dog.]]
* KnightOfCerebus: A minor one; he doesn't drain all of the comedy from a scene, but his sociopathic tendencies are ''not'' PlayedForLaughs and he makes the Turtles question their sense of ethics in a case of HeWhoFightsMonsters in the first episode where he takes center stage.
* LackOfEmpathy: It provides a major ethical dilemma for the Turtles.
* LightningBruiser: As Fishface, he gains rocket boots that allow him to move faster than when he wa human.
* NamesToRunAwayFromReallyFast: Sounds like "sever", and he uses knives.
* TheNapoleon[=/=]PintSizedPowerhouse: Once mutated into Fishface, he is the shortest (even with the robot legs) and smallest member of the Foot Clan, but can still put up a fight.
* NoCelebritiesWereHarmed: His look as a human is based on Jim Kelly, the famous martial artist.
* ObviouslyEvil: He doesn't hide his nature from anyone and has no problems telling people about how he sent to prison,= before Shredder broke him out.
* TheOnlyOneAllowedToDefeatYou: He says it to Raphael when he saves Raph from one of Stockman's traps.
* OptOut: [[spoiler:When asked if he wants to help defeat the zombified Shredder, Kavaxas, and Tiger Claw, he says that things are getting too weird for him, and that he'd just rather go back to basic, street level crime instead]].
* OutOfFocus: Was sidelined for several episodes after becoming Fishface, not doing much of anything until being upgraded. Shredder even mentioned that he was barely worth keeping around.
* PsychoForHire: He says so to Raph:
-->'''Raphael''': "So, you do all this because you owe Shredder?"\\
'''Fishface''': "Eh, mostly I like having a job where I get to crack skulls every day."\\
'''Raphael''': "[[NotSoDifferentRemark Okay, I can relate to that]]."
* RedOniBlueOni: The blue to Bradford's red.
* TheRival: To Rahzar.
* ScaryBlackMan: Though not as dark as other examples, so he may be Black Hispanic or Brazilian instead.
* SlasherSmile: He often has one of these as a human. However, since he is unhappy with his transformation, Fishface doesn't smile as much.
* ScrewThisImOuttaHere: [[spoiler:After he sees Shredder CameBackWrong courtesy of Kavaxas, Xever/Fishface helps the Turtles against the Foot Cultists, tells them a few things, and then beats it.]]
* TheSociopath: Has no regard for any form of life whatsoever, is completely morally [[TheUnfettered unfettered]], and displays many other sociopathic traits. "Baxter's Gambit", however, does show a slightly softer side of him in his interaction with Raphael.
* TakingYouWithMe: [[spoiler: Kicks Bradford into the black hole in "Annihilation Earth!" before being sucked in himself.]]
* TheTeamBenefactor: WordOfGod implies that Fishface's underground mutant entertainment ring is one of several sources of income for the Foot Clan.
* TeethClenchedTeamwork: Has a mutual hatred of Bradford despite the fact they're usually the ones assigned to work with each other the most. [[spoiler: In "The Forgotten Swordsman", he's visibly fuming at having to retrieve Bradford's drowned corpse from the river.]]
* TookALevelInBadass: Once Stockman finishes his new legs and breathing tool, he quickly shows in "The Pulverizer" that his new legs are even ''more'' versatile than his original ones, and on top of that, he has venomous teeth.
* UnexplainedRecovery: [[spoiler: He somehow survived his apparent death in "Owari" and returns alive in the fifth season.]]
* TheUnfettered: Described as such by Raph.
* VillainDecay: He's mostly relegated to a comedic role in season two, where he's slapped around by the Shredder to make a point, demonstrates more submissive behavior in regards to Tiger Claw (though this may be a skill difference and instincts taking prominence), that jar with his general control of the situations he was in season one. His level of competence has also gone down, as in "The Invasion", he was defeated by an exhausted Leo in ''one hit''. He starts to get some of his villainy back in season three, shown when he beats Zeck in a fight using his dark wit and cunning, and even gets to be the main antagonist of an entire episode, running an underground mutant entertainment ring.
* VillainousFriendship: A Downplayed Type 4 with the Shredder. Like Bradford, the Shredder doesn't really care for him, but finds him useful enough to spring from jail and even commissions robot legs for him to stay in the fight. Unlike Bradford, Montes isn't necessarily loyal to the Shredder, mostly just in it for the thrills.
* VillainousRescue: [[spoiler:He actually helps the Turtles fight off several of the Foot Cultists by shining a lantern when they were getting ready to overwhelm them. He then gives them info on the Cultists being mutated humans before he bails out of the Foot Clan.]]
* WasOnceAMan: After turning into Fishface.

[[caption-width-right:150:[-Stockman-Fly-] ]]

A bug-eyed mad scientist who shares a complete knowledge of inventing and genetic mutations with the Foot Clan. He used to be a TCRI employee, but was fired for a spilled copier toner incident so he decided to take revenge on all those who ever mocked him. However, after 2 solo outings against the Turtles, he and his MOUSERS accidentally interfered with a plan to destroy them that happened to have been masterminded by the Shredder, and luckily for him, the Shredder spared his life, impressed enough with skills to take him as a subordinate. Finding little respect from his new teammates, he turned on them and briefly went solo again, before being brought back to the Foot Clan. He becomes a mutant housefly when botched experiment ideas result in Shredder mutating him; [[spoiler: Baxter's the third to last human member of the clan to mutate, with Karai following a few episodes later (partially due to Stockman's help) and Shredder mutating by Stockman's hand in the fourth season.]]

* AccidentalMisnaming: People [[RunningGag will frequently]] get his name wrong every appearance after "I Think His Name Is Baxter Stockman". Even ''he'' got his own name wrong at one point.
* AdaptationalUgliness: This grosser incarnation of his Fly form makes the 1987 version adorable by comparison.
* AfroAsskicker: When in the more dangerous version of his PoweredArmor.
* AttackItsWeakPoint: His head was left exposed after the Stockman-Pod upgraded into a HumongousMecha.
* AntiVillain: In "The Lonely Mutation of Baxter Stockman", he only wishes to become human again, either via Donatello's Retro Mutagen, or more horrific means such as dipping a human in Mutagen and then going in himself, the results of which probably wouldn't even work.
* BeCarefulWhatYouWishFor: When first mutated, he wanted nothing more than to cure himself of it, constantly trying to make his own retro-mutagen and failing. By the time of his last appearance, upon being demutated, Stockman ungratefully yells at Mikey for, as he had begun to ''like'' being a mutant fly, due to the factbl that he was "smarter, stronger, and people liked him" in spite of being super disgusting.
* BigCreepyCrawlies: After his mutation.
* BlackAndNerdy: He is black and is a nerdy scientist.
* BodyHorror: His mutation was one of the most grotesque of the show.
* BroughtDownToNormal: He gets retro-mutated back into a human with one of Donatello's Retro Mutagen grenades in "Owari", and he actually does not take this well due to losing his abilities as a fly.
* ButtMonkey: Got this a lot back when he worked at TCRI, and it doesn't get better when he meets the Turtles and is pressed into the Foot Clan.
* CardCarryingVillain: Doesn't seem to deny that he's this trope, when Michelangelo asks why he's a villain.
* CompositeCharacter: He appears to be based on the comic book and 2003 versions in name and ethnicity, but his design (hairstyle, clothes, and physique), personality, and threat level borrows aspects of the version seen in the 1987 series. As of "The Lonely Mutation of Baxter Stockman", he has become a mutant fly, another trait of his 1987 counterpart. [[spoiler: He also appears to have [[HiddenAgendaVillain ulterior motives]] in his services to the Foot Clan, like his 2003 version, if his holographic chart in "The Noxious Avenger" means anything.]]
* TheDogBitesBack: After being picked on for almost every episode by the Turtles and threatened by his higher-ups, he decides to take payback in "Baxter's Gambit".
* DoomyDoomsOfDoom: To the point that everyone could see it coming from a mile away.
* EvenEvilHasStandards: In "The Super Shredder", he initially refuses to [[spoiler: infuse Shredder with the rest of the mutagen, insisting that the mutagen is unstable and could have disastrous side effects. Of course, he quickly gives in when Shredder threatens him with death.]]
* EvilCounterpart: He loves technology, [[NotSoHarmless can be quite dangerous]] even though he's [[ButtMonkey mocked and sometimes even underestimated by his coworkers]], likes wearing purple and is kind of a dork, much like Donatello.
* EvilGenius: His role when working for the Shredder or when trying to use it to be a solo villain.
* EvilIsHammy: Nowhere near as much as his 2003 counterpart, but he still has his moments.
* ForcedTransformation: Was originally human before being turned into a fly mutant. [[spoiler:When Stockman is returned to his human form in "Owari", he complains, saying that while he looked disgusting as a fly mutant, he was smarter, stronger, and faster.]]
* FourEyesZeroSoul: Played with. While he's a bad guy who wears glasses, he lacks the cold-blooded sociopathic nature that generally comes with this trope.
* IJustWantToHaveFriends: Deep down, he just wants to have people sincerely like and respect him. This is the primary reason he hates being returned to being a human, as he had gotten smarter with his science and Shredder had begrudgingly complimented him on both his loyalty and his perfection of the [[spoiler:Super Shredder]] mutation while he was a mutant fly.
* KickTheDog: When he's got the [[spoiler: insane Splinter locked up]], he offers him cheese, only to eat it himself at the last second.
* LaughablyEvil: His dorky demeanor and tendency to get angry over the Turtles insulting him made him quite entertaining. He loses this trait briefly after he becomes a fly mutant, however, but even after becoming a source for comic relief, he's not ''quite'' as LaughablyEvil as he once was. Even after becoming a fly mutant however, he still has some genuinely comedic moments such as when he gets into a WimpFight with Pigeon Pete in the episode, "Clash of the Mutanimals".
* MadScientist: Both in the sense of being angry at the world and not being very sane. Stockman starts as a typical deranged scientist, but he becomes an Eggman/Wily/Hojo grade Mad Scientist once he mutates, as this actually helps him mastermind plot-altering experiments [[spoiler:such as Karai and Shredder's mutations]] and gives him some fighting abilities against the Turtles, but he also slips further into insanity.
* NerdGlasses: Going with his nerdy portrayal in the series. He loses the glasses when he mutates, no longer needing them.
* NoRespectGuy: Comes with being a huge ButtMonkey. He does start get some slightly more civil treatment following his mutation and subsequently more or less complete loyalty to Shredder.
* NotSoHarmlessVillain[=/=]IneffectualSympatheticVillain: He treads the line between these two, the latter to the extent that in his first appearance, Mikey actually suggests that they get him some ice cream rather than kick his butt. After he mutates, he goes off the deep end but also becomes more competent with his experiments; [[spoiler:Stockman's the one who created the mutagen that ensnares Karai and later created the brainwashing worms used on her, and then he mutates Shredder into Super Shredder later]].
* PoweredArmor: He had one in his first appearance. It was initially kind of crappy, but was upgraded by the T-Pod.
* RobotMaster: He uses machines to win his fights often, ranging from his powered suit to the mousers.
* SanitySlippage: After his mutation into a fly in "The Lonely Mutation of Baxter Stockman", he's become far less trusting and crazy thanks to it.
* SlasherSmile: When he uses the T-pod to upgrade his armor, he tries this, but it turns out too pleasant and goofy. He improves it in "Baxter's Gambit".
* StrawLoser: As part of being a villainous nerd, his pathetic nature almost makes him pitiable despite his clearly evil intentions.
* TrademarkFavoriteFood: After mutating into a fly, he has started to constantly eat candy bars.
* TookALevelInBadass: Once he mutates into a fly, he dismantles a Foot Bot and subdues Rahzar long enough to escape temporarily. He also proves to a more difficult opponent for the Turtles without any technological aid, and begins to mastermind much more dangerous and plot-altering experiments, [[spoiler:such as the mutagen for a trap that accidentally mutated Karai, the worms that brainwash her, and then the mutation of Shredder]].
* UncertainDoom: In "Owari", he's [[spoiler:demutated by the Turtles, and last seen knocked out by Mikey before the Shredder sets the mansion on fire with a molotov cocktail. He's not shown amongst the surviving members of the Foot Clan in the next season (he's never shown again ''at all''), but his death remains unconfirmed.]]
* UndyingLoyalty: He becomes a relatively loyal and active member of the Foot Clan after his mutation and when it's clear that staying with them is his best shot at becoming human again. In "Owari" he even loudly declares that nobody can stand against [[spoiler: the Super Shredder, his last creation before being de-mutated back into a human]], having become pretty fanatical by that point.
* UngratefulBastard: [[spoiler: When he's returned to human form by the Turtles, he complains that he liked the strength, speed, and intelligence he had as a mutant. Mikey punches him for being ungrateful.]]
* UsedToBeASweetKid: "Baxter's Gambit" has him talk about his backstory, and he states that he used to be a nice kid. [[UnreliableNarrator It's not easy to guess if he's telling the truth or not.]]
* WasOnceAMan: He gets turned into a fly mutant in "The Lonely Mutation of Baxter Stockman". "Owari" features him getting changed back into a human with retro-Mutagen.
* WhatHappenedToTheMouse: Baxter's final appearance in the series was in the Season 4 finale "Owari", where he is de-mutated by Mikey. While everyone else in the Foot Clan was either killed ([[spoiler:Shredder, Rahzar]]) or parted ways ([[spoiler:Fishface, Tiger Claw, Bebop, and Rocksteady]]), it is never explained what happened to Baxter after that episode.
* WhosLaughingNow: His motivation, though he hasn't been very good at his revenge schemes so far.

-->'''Voiced by:''' Creator/EricBauza

->''"When have I ever failed you, Master Shredder?"''

The most feared assassin in all of Asia, the Shredder hired him to help him in his fight against the Hamato Clan.

* AnArmAndALeg: [[spoiler:Gets his right arm cut off by Alopex as a warning that she could've just as easily taken his life.]]
* ArchEnemy: Is this with Alopex.
* ArtificialLimbs / SwissArmyAppendage [[spoiler:Used to replace his right arm.]]
* AsskickingLeadsToLeadership: He's Shredder's new second-in-command in New-York, and the new leader of the Foot Clan after [[spoiler:Shredder's death in season 4 finale]] and is, fittingly, by far the most skilled and dangerous of Shredder's lieutnants, save for Hattori Tatsu,being often able of taking on the four turtles and other fighters on his own. Only Splinter, the Shredder himself, Alopex and Tatsu can be considered better fighters than him.
* BackstabBackfire: [[spoiler:When he attempts to shoot Alopex in the back after she spares his life, she darts back and cuts off the arm that he's using his gun in.]]
* BarefootCartoonAnimal: He doesn't wear shoes.
* BigEater: Loves to eat, whether it's skim milk, fish, or cheesy junk food.
* BodyHorror: Not quite as bad as other examples, but for starters, his tail was cut off when he was first introduced. When he comes back, he's missing his left eye and part of his right ear. [[spoiler:In "Tale of Tiger Claw", he loses another body part to his sister Alopex, his right arm.]]
* BreakoutVillain: The most popular addition to the mythos introduced in the show, and a character that WordOfGod would like to see become a recurring character in subsequent adaptations. Tellingly, he's the only member of the Foot Clan outside of the Shredder who doesn't undergo a large amount of VillainDecay, gets the most character development, and becomes the most important Foot character besides Shredder and Karai.
* CainAndAbel: [[spoiler:Alopex and Tiger Claw are brother and sister who have grudges against each other. However Alopex, despite hating him for killing their parents, spares him. Tiger Claw immediately tries to shoot her in the back, but she dodges and slices his arm off.]]

* CatsAreMean: He's a mutant tiger who associates himself with the villainous Foot Clan.
* CatsAreSuperior: He's a tiger warrior who's very overconfident in his ninja skills.
* ConservationOfNinjutsu: How effective and dangerous he is to the turtles and their allies often depends of whenever he is facing them alone or with the Shredder and/or other Foot clan lieutenants. When alone he often is able of facing the turtles and their allies by himself, and even have the upper hand in several occasions, but is fought more evenly and even suffers AmusingInjuries such as being hit and run over by a van or [[GroinAttack punched in the crotch by April]], when with his fellow Foot Clan members.
* CorporalPunishment: One of his duties as TheDragon is to inflict this upon the lower Foot Clan members should they fail or particularly piss off Shredder. He gets to deal it out on Bebop and Rocksteady at the end of "Attack of the Mega Shredder".
* {{Determinator}}: He manages to cut his way out of the Kraathatrogon, defeat the 1987 Turtles, and jump through dimensions, defeating every enemy in his way, including a whole army of Kraang, all to return and have his revenge.
* TheDragon: Despite being a bounty hunter, he becomes Shredder's top lieutenant full-time after Karai defects, and serves him faithfully. This is reinforced in "Owari", where he's the last of the Inner Circle to fall to the Turtles before they face Super Shredder.
* DragonAscendant: The fifth season shows that Tiger Claw is now in charge of the Foot Clan [[spoiler: since Shredder was killed by Leo. His goal now is to revive Shredder, which is why he releases Kavaxas and presses him into the Clan.]]
* TheDreaded: Has this reputation thanks to being far and away the most powerful member of the Foot Clan besides Shredder himself. His appearance on the battlefield is a real cause for alarm and any battle he joins immediately becomes an uphill one for the Turtles.
* EnemyMine: Once his [[spoiler:usefulness as Kavaxas's master is expired and Undead Shredder destroys the Seal of the Ancients to start TheEndOfTheWorldAsWeKnowIt, Tiger Claw wastes no time in trying to blast Shredder and help the Turtles defeat Kavaxas. After Kavaxas and Undead Shredder are defeated and sent back to the Netherworld, Tiger Claw declares a truce with the Foot Clan now in an even deeper hole.]]
* EqualOpportunityEvil: He states that racism is ridiculous and he would never distrust or dislike a person only because they are a dog mutant, even though he is a feline.
* EstablishingCharacterMoment: He makes his respect for the Shredder and disdain for the Foot Clan apparent very quickly, and when Karai is about to attack Tiger Claw, he pulls a gun on her without skipping a beat.
* EvenEvilHasStandards:
** Though he did not try to stop it, he was somewhat unnerved when he believed Shredder planned to mutate Karai.
** He's becoming increasingly resentful of Shredder regarding his apathy towards the fate of humanity at the hands of the Kraang.
** He's horrified when [[spoiler: Shredder kills Splinter before the latter can save the Earth from the Triceratons, his master happy to let the Earth be destroyed if he can triumph over Splinter.]]
--> [[spoiler:'''Tiger Claw:''' "Shredder, what have you done?!"]]
--> [[spoiler:'''Shredder:''' "Hamato Yoshi is finished! The Earth can be destroyed for all I care! I have finally won!"]]
** He's equally horrified when [[spoiler: he discovers that Kavaxas was [[EvilIsNotAToy using him as a pawn in order to destroy the world]], and unhesitatingly teams up with the Turtles to stop him.]]
* EvilIsNotAToy: [[spoiler:In the first episode of the fifth season, he summons Kavaxas to Earth to resurrect the Shredder for him, using the Seal of the Ancients to keep him in line. Three episodes later, Kavaxas does so... but Shredder CameBackWrong as the demodragon's puppet and destroys the Seal of the Ancients, allowing Kavaxas to begin TheEndOfTheWorldAsWeKnowIt.]]
* EvilVersusOblivion: In "End Times", when [[spoiler: Kavaxas betrays him and brings about the apocalypse, Tiger Claw has no desire to see the world end and willingly teams up with the Turtles to stop him]].
* {{Expy}}:
** Of Boba Fett from ''Franchise/StarWars'', especially with the ShoutOut of the Boba's defeat by jetpack and Sarlacc.
** He also bears a number of similarities to [[Franchise/GIJoe Major Bludd]], since both are powerful international mercenaries who've lost an eye and an arm, have a number of high tech gadgets at their disposal, and combat a ragtag bunch of misfit warriors who've wronged them.
** While Tigerclaw himself is an OriginalCharacter, he bares a heavy resemblance to Old Hob from the [[ComicBook/TeenageMutantNinjaTurtlesIDW IDW comic series]]; a humanoid cat-mutant with an affinity for guns with a grudge against the Hamato Clan for the loss of his eye
* EyepatchOfPower: His journey through dimensions, fighting his way home, seems to have cost him an eye.
* FamilyUnfriendlyViolence: On the receiving end in "Tale of Tiger Claw" when Alopex [[spoiler: slices his arm off, ''on-screen''. We even see the severed arm laying limp on the ground.]]
* FemaleFelineMaleMutt: Inverted. [[spoiler:He was mutated into a humanoid tiger while his sister Alopex was mutated into a female fox]].
* FreezeRay: One of his weapons that he employs in combat, presumably to assist in capturing opponents alive.
* FurryConfusion: In "Owari" it's revealed that he owns pet tigers, despite being one. [[FridgeBrilliance Then you remember that he was formefly human]], and likely doesn't see anything wrong with owning non-anthropomorphic tigers as pets.
* GoodScarsEvilScars: He's Shredder's [[TheDragon Dragon]], and is missing his tail, and later loses an eye and his right arm, and gains an EarNotch.
* GroinAttack: April eventually masters an ability called "Dragon's Tail", and uses it to give Tiger Claw one of these, knocking him out. And this is after Casey gave him one.
* HeelFaceTurn: [[spoiler: He forms a truce with the Turtles once Kavaxas and Zombie Shredder are defeated. Unfortunately, this happens in his final episode.]]
* TheHeavy: While Shredder is incapacitated, Tiger Claw is the most prominent antagonist in the fourth season.
* InvincibleVillain: While it's not to the same extent of the Shredder, Tiger Claw counts as this since the Turtles are usually incapable of defeating him in fights, let alone landing any blows on him. Heck, it wouldn't be surprising to see him comfortably fair well or be on par with the Shredder himself.
* {{Jerkass}}: He doesn't seem to particularly care about Shredder's Foot Clan, and makes that thought known when Karai talks badly of him.
* {{Jetpack}}: He has one that allows him to obtain an aerial advantage.
* KickTheDog:
** In "The Wrath of Tiger Claw", he has no qualms against harassing Murakami, a blind old man, for information on the Turtles. Karai is [[EvenEvilHasStandards disgusted]].
-->'''Karai''': There's no honor in this.\\
'''Tiger Claw''': I didn't come here for honor.
** In "Owari", [[spoiler: he mocks Splinter's death to Leo's face.]]
-->'''Tiger Claw''': Do you feel it, boy? The weight of the world crushing you, now that [[spoiler:your sensei is gone?!]]
* KnightOfCerebus: He's not a very funny character and, much like his master, episodes where he's prominent are bound to be more serious. See TheDreaded as well.
* KnownOnlyByTheirNickname
* TheMusketeer: Tiger Claw uses a machete for melee combat and two {{Ray Gun}}s for long range battle.
* MyGodWhatHaveIDone: His reaction in "End Times" when [[spoiler:he realizes he was Kavaxas' UnwittingPawn all along]].
* NotSoAboveItAll: While scoffing at the idea that he and Bradford wouldn't get along because he's a cat and Bradford's a dog, he comments that he does want to eat Xever because he's a fish.
** He has always been the most serious, strict and stoic of the villainous mutants, but "Meet Mondo Gecko" shows him among the crowd of villains watching Xever's underground racing event, which he enjoys with a bag of popcorn and gets pretty pumped up during the race.
* OnlySaneMan: He is this in the Foot Clan when you compare him to its other members. Shredder has been driven insane with his desire for vengeance on Splinter, Bradford is fanatically loyal to Shredder, Xever is an AxCrazy immoral killer, Bebop and Rocksteady are bumbling, largely comical forced recruits, and Stockman has lost a great deal of his sanity.
* PantheraAwesome: He's a mutant tiger and is consistently a tough opponent for the heroes.
* PetTheDog:
** Despite his hatred for Karai, he tries to assure Shredder that the Hamato Clan will pay for [[spoiler: her mutation]], upon seeing how distraught he was about it.
** In "Annihilation Earth!", he's probably the biggest team player during the Foot Clan's brief alliance with the Hamato Clan against the Triceratons, helpfully providing cover fire and support for April and Casey.
* ThePowerOfHate: Claims this allowed him survive being swallowed by the Kraathatrogon and make his way home after being stranded in the 1987 universe.
* ProfessionalKiller: He's described as "Asia's deadliest assassin" in his introduction. The only one who has ever managed to defeat him was ''Splinter himself''. The closest thing to a victory any of the Turtles have had against him was when Leo knocked him down briefly in "The Invasion".
* PromotionToOpeningTitles: He appears in the opening in his first appearance, "The Manhattan Project".
* PunchClockVillain: While loyal to the Shredder, Word of God is that Tiger Claw did ''not'' intend to stay with the Foot Clan for the rest of his life before season five.
* PutOnABus: According to WordOfGod, "End Times" is Tiger Claw's last appearance in the series.
* RocketPunch: [[spoiler: His mechanical arm can fire its fist at his opponents.]]
* ScarfOfAsskicking: Has a nice-looking blue scarf, and Tiger Claw has had to fight out of Dimension X more that once, including when he was originally mutated with Alopex.
* SeeksAnothersResurrection: In the fifth season, [[spoiler:his primary goal is to bring the Shredder BackFromTheDead. It's the entire reason he summons Kavaxas.]]
* PoliticallyIncorrectVillain: Coinciding with his having TookALevelInJerkass, in "The Wrath of Tiger Claw", he has absolutely zero qualms against threatening Murakami, a blind man, for information on the Turtles' location.
* ThatPoorCat: In "Casey Jones vs the Underworld", after Casey delivers a GroinAttack to him. Again in "City at War", when April uses the "Dragon's Tail" move to give him another GroinAttack.
* ThenLetMeBeEvil: Ever since his mutation, he feels as if cannot go back to his normal life anymore. Instead, now accepts being the monstrous mutant he is now.
* TookALevelInJerkass: He was villainous but still honorable in his first appearance. Upon his return, his honorable side was no more and he's just now filled with rage and focused solely on revenge, but eventually it began to even out again as he began showing more shades of EvenEvilHasStandards again.
* UnwittingPawn: In "End Times", [[spoiler:it turns out that he was this to Kavaxas all along; Kavaxas needed his help to accomplish three objective in order to bring about TheEndOfTheWorldAsWeKnowIt: killing a strong warrior (Tatsu), resurrecting an evil warrior (Shredder), and destroying the Seal of the Ancients that was used to keep Kavaxas in line.]]
* VillainousFriendship:
** Has a mutual sense of respect for Bradford. This doesn't save Bradford from being subjected to a beating for his failures, however. [[spoiler: Tiger Claw goes through the trouble of having his corpse retrieved from the bottom of the river and has Kavaxas bring him back to life.]]
** He has a more genuine one with the Shredder, as he's the only lieutenant who regularly receives genuine respect from his master. Shredder is much more willing to listen to him on matters, [[spoiler:and even when he's become the raging, insane Super Shredder, he still audibly softens when Tiger Claw tries to get him to rest and calls him "old friend".]] It's to the extent that his main goal in the fifth season is to [[spoiler:use Kavaxas' power to resurrect the Shredder.]]
* WasOnceAMan: He was only a child when he was mutated.
* WeUsedToBeFriends: With Alopex. His sister from his time as a young human boy, who was mutated alongside him, fought alongside him, and then betrayed him after she found out he killed their parents.
* WorthyOpponent: He develops a serious level of respect for Splinter, marveling at him fighting off a deadly poison after nearly killing him.

[[caption-width-right:150:Rocksteady]]

A Russian rock-head who provides more-advanced weapons and security for the Foot Clan. He used to be a Russian arms industry officer who allied with the Shredder as a business partner in the mafia, but his attempts to steal Shredder's helmet and hunt Karai in exchange for a safe departure from the Kraang-invaded city, which were thwarted by the Turtles, got him captured and, luckily for him, Shredder had him work full time in the Foot Clan as punishment for his minor betrayal. He becomes a mutant white rhinoceros.

* ActorAllusion: This would not be the first or the last time Creator/FredTatasciore played a Russian Rhino supervillain in New York City, having played the Rhino in five different ''ComicBook/SpiderMan'' games.
* AdaptationalBadass: This version of Rocksteady is more dangerous and difficult to take down than the 1987 version.
* AdaptationalIntelligence: He's more capable of formulating a plan and improvising when it goes wrong than the 1987 Rocksteady.
* AdaptationalNationality: In the previous adaptations that Rocksteady appeared in, he was portrayed as being an American. In this adaptation, he is a Russian.
* AffablyEvil: At least when interacting [[OldFriend with Shredder anyway]].
** And later with [[VitriolicBestBuds Zeck/Bebop]].
* AllThereInTheScript: His name is only shown in the end credits in his debut episode; it is mentioned in "The Legend of the Kuro Kabuto".
* AmbiguouslyGay: He displays some interest in his pal Bebop and has some effeminate qualities in his character. See ShipTease.
* AppropriatedAppellation: When Mikey is told to distract him and Zeck, he gives them the names "Bebop and Rocksteady". Ivan Steranko ''loves'' the moniker of Rocksteady.
* ArmsDealer: His role in "Enemy of My Enemy".
* AscendedExtra: He had a minor role in his debut episode before becoming the [[CanonCharacterAllAlong 2012 version of Rocksteady]].
* {{BFG}}: Wields a weapon which is more or less a Gatling gun.
* BodyHorror: His Golden Knuckles and shoulder pads are melted into his flesh after his mutation into Rocksteady.
* TheBrute: Begins sharing the role with Bradford in the Foot Clan after being mutated.
* CanonCharacterAllAlong: For the first two seasons, he appears to be a completely original character who functions independently. In season three, he is hit with mutagen and becomes the 2012 version of Rocksteady.
* CharacterizationMarchesOn: His first two appearances were more stoic and businessman-like, while his later appearances [[{{Flanderization}} play up his Russian aspect]] and he seems to have a few CloudCuckoolander traits, particularly after becoming Rocksteady.
* TheCollectorOfTheStrange: As of the episode "The Legend of The Kuro Kabuto", he reveals that he has been after The Shredder's Helmet for quite awhile, though none of the thieves he has hired have succeeded in stealing it, indeed, they have failed to even come back alive, He says this is because "The Shredder has eyes in back of head." One has to wonder how he has managed to keep his involvement in the numerous theft attempts a secret. Steranko's collection isnt really that strange, but it does have a collection of rare antique military weaponry, and a large stuffed polar bear, among other things
* TheComicallySerious: Due to his lack of skills with the English language, he's prone to messing up common sayings, but has no idea how goofy he really sounds.
* DarkIsEvil: He dresses in all black. It's later [[Subverted subverted]] when he becomes Rocksteady.
* DivergentCharacterEvolution: Played with. While this Rocksteady keeps most aspects of the 1987 version's design, he has gold knuckles and shoulder plates.
* EarlyBirdCameo: He makes a brief appearance in "Enemy of My Enemy" before becoming a supporting then main cast member.
* EvenBadMenLoveTheirMamas: Rocksteady very much loves his mother. [[spoiler: It's how Bebop convinces him to pull a HeelFaceTurn and save the world.]]
* EvilSoundsDeep: It's Fred Tatasciore behind the mic, voice of [[ComicBook/TheIncredibleHulk Hulk]] and [[VideoGame/CallOfDutyZombies Nikolai Belinski]] (the latter of whom shares a dialect and the exact same delivery as Steranko), after all.
* EvilVersusEvil: Though Shredder trusts him enough to make deals with him, Steranko is actually really only out for himself, to the point of trying to steal the Shredder's helmet.
* {{Flanderization}}: His HuskyRusskie traits become more played up as time goes on, and while he was [[TheComicallySerious Comically Serious]] as a human, after he mutates into Rocksteady he becomes more of a DumbMuscle and a {{Cloudcuckoolander}}. Whether this is due to his "career change" or an effect the mutagen had on his mind is anyone's guess.
* {{Foil}}: To Zeck, being a bigger, stronger fighter, though with a slightly skewed grasp on reality, and whom gets used to his mutation fairly quickly and accepts the Rocksteady name wholeheartedly.
* GeniusBruiser: He's fairly cunning and quite the powerhouse in battle.
* HammerAndSickle: To fit his Russian background, Rocksteady's trademark weapons are a matching set of a hammer and sickle.
* HeelFaceTurn: [[spoiler: After expressing horror at Kavaxas' evil and the 1987 Shredder and Krang's attempt to destroy the world, Rocksteady and Bebop decide to give up villainy for good and become superheroes.]]
* HonorBeforeReason: Rocksteady is a man of honor, being aghast when the Turtles use ExactWords against him and refraining from killing the 1987 Turtles when they're down.
* HuskyRusskie: He comes from Russia and is a pretty big guy.
* HypercompetentSidekick: Rocksteady and Bebop are both this when it comes to working for the 1987 versions of Shredder and Krang, from being able to complete all their missions successfully to [[spoiler: being able to totally curbstomp both the 1987 versions of Shredder and the Turtles alike]].
* ImplacableMan: After transforming into Rocksteady, it becomes damn near impossible to knock him down and outside of Aliens and Martial Arts Masters he's the only one seen to overpower a ''Triceraton'', easily treating one as a punching bag.
* InstantCostumeChange: A weird example: Steranko's pants switch from all-black to camo print after being mutated.
* KarmaHoudiniWarranty: Turns out Shredder does end up tracing Zeck's attempt to steal his helmet back to Steranko, captures them both, and mutates them. Seems Steranko should've taken that "eyes in the back of his head" notion a little more to heart.
* LightningBruiser: He's a huge guy, but he's just as quick on his feet in battle. Even more so as Rocksteady, being a rhino and all.
* TheManBehindTheMan: To Zeck in "The Legend of the Kuro Kabuto" and the Purple Dragons in "A Chinatown Ghost Story".
* OldFriend: Explicitly says that he and Shredder are this. According to him before being mutated, for at least 10 years. However, he later hires Anton Zeck to [[EvilVersusEvil steal Shredder's helmet]].
* PowerFist: He appears to be wearing golden brass knuckles, with hammer and sickle insignias on them. After being mutated into Rocksteady, [[BodyHorror they're melted into his flesh]]. He puts them to good use in his first fight with the Turtles in "Serpent Hunt", leaving a sickle imprint on Raph's forehead.
* PromotionToOpeningTitles: As Rocksteady.
* RedRightHand: His fake eye, which he got because Zeck accidentally shot his eye out. Lampshaded when Zeck tries to make him feel better about it, telling him that before he was just a regular arms dealer, and now people will think of him as "the cool eyeball guy".
* ScrewThisImOuttaHere: Both he and Bebop bail out of the Foot Clan [[spoiler:after Shredder [[CameBackWrong Comes Back Wrong]] thanks to Kavaxas and helps the demodragon start the end of the world.]]
* ShipTease: He's gotten a few moments with Bebop, including [[spoiler: holding each other as they die in "Annihilation Earth!",]] proclaiming he loves him in "Half-Shell Heroes" (even though it was largely PlayedForLaughs), and the two of them holding hands to share Bebop's invisibility, then giving each other an odd look as they realize they're still holding hands and slowly separate in "In Darkest Plight". Rocksteady is also holding Bebop in a protective position when [[spoiler:Undead Shredder is brought to life by Kavaxas]]. Their moment of holding hands with hearts in the background during "The Big Blowout" make it ''very'' unlikely there isn't anything more than friendship between the two, either.
* SpellMyNameWithAThe: Occasionally refers to himself as "The Rocksteady".
* SpikesOfVillainy: He has two shoulder pads with spikes on them.
* TheStarscream: Plotting to overthrow Shredder with Zeck/Bebop. [[spoiler: They eventually defect from the Foot Clan and pull a HeelFaceTurn]].
* ThemeNaming: With Zeck. Both have the surnames of classic Marvel Comics artists.
* ThirdPersonPerson: Tends to refer to his full name when referring to himself.
* TookALevelInDumbass: Once an intelligent mob boss who had the respect of Shredder himself, Rocksteady soon became the DumbMuscle upon getting mutated.
* TheUnfought: He gets electrocuted into submission before he can put up any kind of fight. In his first proper starring appearance in "Serpent Hunt", he gives the Turtles a hell of a fight and only gets worse after his mutation.
* VillainDecay: He was once a powerful mob boss with his own organization, but Shredder turned him into his DumbMuscle that obeyed his every command.
* VitriolicBestBuds: With Zeck/Bebop. [[spoiler: When they're being sucked into a black hole to their deaths, they hold each other so they don't have to die alone.]]
* WasOnceAMan: Is mutated into Rocksteady by Shredder for both being behind the theft of the Kuro Kabuto helmet and for trying to hurt Karai.
* TheWorfEffect: Goes down incredibly quickly at the hands of [[spoiler: a brainwashed Karai]].

[[caption-width-right:150:Bebop]]

A master thief who can turn invisible, along with a host of other gadget powered abilities. Works as Steranko's agent. He becomes a mutant warthog.

* AdaptationalBadass: While he is still incredibly goofy, he is a BunnyEarsLawyer and a genuinely good fighter rather than the incompetent idiot his 1987 counterpart was.
* AdaptationalSlimness / AdaptationalCurves: The previous versions of Bebop have traditionally been fat and big, while this Bebop is slim and fit (and smaller), even after becoming a warthog mutant. [[ShownTheirWork This makes sense, given that warthogs aren't that fat in real life, and are actually smaller than rhinos]].
* AffablyEvil: At least when interacting [[VitriolicBestBuds with Steranko/Rocksteady anyway]].
* AmbiguouslyBi: He has some ShipTease moments with Rocksteady, but unlike the Rhino, Bebop has also admitted that he's a ladies man too.
* AppropriatedAppellation: Averted. Unlike his partner Rocksteady, Bebop absolutely hates his new moniker.
* BattleBoomerang: He can throw mohawk shaped [[EnergyBall energy bolts]] that can boomerang back to him from [[FightingClown his mohawk.]]
* AtrociousAlias: He [[LampshadeHanging lampshades]] how silly and nonsensical his mutant name is, but the other characters (including his partner) continue to refer to him with it anyway, much to his chagrin.
* BerserkButton: ''HATES'' being called Bebop. Though he at least tolerates it from Rocksteady.
* BewareTheSillyOnes: While he might look like a joke compared to the likes of the Shredder, this ain't [[WesternAnimation/TeenageMutantNinjaTurtles1987 your dad's]] Bebop. Before he was mutated, he was a master thief with a suit that makes him invisible, shoots lasers, lets him skate on light-rails and a host of other gadgets. When he tries to steal the Kuro Kabuto, he manages to nick it from the Shredder's lair without getting caught and runs circles around an army of the mutants and ninjas, only failing due to bad luck. Even mutated, he is still able to hold his own when fighting the Turtles despite having no official martial arts training to speak of.
* BlindWithoutEm: His mutation caused him to lost his sight, forcing him to keep his visor on to see.
* BodyHorror: Parts of his costume appear to have merged into his flesh after becoming Bebop.
* BunnyEarsLawyer: He's a very competent thief, but he's extremely eccentric. When Steranko questions his ability to steal Shredder's helmet, Zeck tells him to lick his SpearOfDestiny, revealing that he replaced the real spear with one made of marzipan, just to prove he could. The fact that Steranko does this without hesitation seems to imply that Zeck does that kind of thing all the time.
* CallingCard: Because of his gigantic ego, he actually throws his business card at Rahzar just before making his exit.
* CanonCharacterAllAlong: He is introduced in season two, but gets mutated and becomes Bebop much later.
* DanceBattler: He dances literally every single time he gets into a fight. [[ConfusionFu This is most likely how he manages to throw off the Turtles]].
* DivergentCharacterEvolution: As Bebop, he is much less bulky than the 1987 version, differentiating him more from Rocksteady. He's also more cynical and irritable than his partner, though the latter is more because of his mutation and the nickname that comes with it.
* DoNotCallMePaul: An inversion, in that he hates his mutant name instead of his real one.
-->'''Bebop''': I am ''not'' gonna be called Bebop, got me? That is the dumbest name ever!
* EvilIsHammy: Pun aside, Bebop is very over-the-top in his personality.
* EyeScream: Post-mutation, his visor seems melded to his head. And may even be his eyes now.
* {{Foil}}: To Steranko, being a slimmer, weaker fighter, who is a bit more of a realist, and whom absolutely hates his mutation and the name, Bebop, that ended up coming with it.
* FragileSpeedster: He's quick on his feet, but is much lankier and more fragile than most of his other versions.
* HardLight: His boots can generate beams of this in the air to skate on, usually between two points. His mohawk energy balls also seem solid, as he can use them as boomerangs.
* HatesBeingNicknamed: While Ivan takes to "Rocksteady" pretty quickly, Anton does ''not'' like being called "Bebop". Later on he lets people address him by it, likely out of resignation.
* HeelFaceTurn: [[spoiler: After expressing horror at Kavaxas' evil and the 1987 Shredder and Krang's attempt to destroy the world, Bebop and Rocksteady decide to give up villainy for good and become superheroes.]]
* HypercompetentSidekick: Bebop and Rocksteady are both this when it comes to working for the 1987 versions of Shredder and Krang, from being able to complete all their missions successfully to [[spoiler: being able to totally curbstomp both the 1987 versions of Shredder and the Turtles alike]].
* InvisibilityCloak: When powered up his suit can make him invisible. He can also plug in some type of cord to apply the affect to his backpack.
* IronicName: This incarnation of Bebop is more of a DanceBattler. Bebop is a type of jazz that created to not be danced to.
** [[FridgeBrilliance That's most likely reason why Zeck hates his nickname]].
* JiveTurkey: Speaks in slang most of the time.
* {{Kiai}}: He makes Music/{{Michael Jackson}}-esque sounds whenever he fights. Donnie points out that he uses it to distract his opponents, while April points out that it makes his InvisibilityCloak pointless.
* {{Leitmotif}}: He's got a very jazzy theme whenever he starts to do his work.
* MotorMouth: He has a tendency to ramble that can be to his detriment, April managing to hit him despite being invisible because he wouldn't shut up.
* MythologyGag: His mohawk and visor match Bebop's from the 1987 show. A not-so subtle hint about his mutation.
* NoCelebritiesWereHarmed: He dances and shouts like Music/MichaelJackson.
* PoweredArmor: His suit allows him to become invisible and create walkways with his TronLines, aside from shooting laser beams and a BattleBoomerang.
* PromotionToOpeningTitles: As Bebop.
* PurpleIsPowerful: His suit has purple TronLines when it's powered on. He can also throw purple boomerangs from his mohawk.
* ScrewThisImOuttaHere: Both he and Rocksteady bail out of the Foot Clan [[spoiler:after Shredder [[CameBackWrong Comes Back Wrong]] thanks to Kavaxas and helps the demodragon start the end of the world.]]
* ShipTease: He's gotten a few moments with Rocksteady, including [[spoiler: holding each other as they die in "Annihilation Earth!",]] Rocksteady proclaiming he loves him in "Half-Shell Heroes" , and the two of them holding hands to share Bebop's invisibility, then giving each other an odd look as they realize they're still holding hands and slowly separate in "In Darkest Plight". Rocksteady is also holding Bebop in a protective position when [[spoiler:Undead Shredder is brought to life by Kavaxas]].
* SkewedPriorities: At the beginning of "The Pig And the Rhino," he seems less upset about being mutated and more upset that the animal that he was mutated into isn't cool enough.
-->'''Bebop:''' Look at me! You turned me into a dang pig! I don't wanna be a pig! Ladies don't love pigs! Can't you turn me something cool, like a mongoose?
* SmallNameBigEgo: "I don't want to be a mutant, I'm too handsome! The ladies love me!"
* TheStarscream: Plotting to overthrow Shredder with Rocksteady.
* TheNicknamer: He calls Ivan Steranko "Big S" and "Baby Ivan".
* TheNoseKnows: After mutating, he uses his enhanced sense of smell to track down the Turtles, saying that his nose is "better than a bloodhound". A case of ShownTheirWork, as warthogs like all pigs have a very acute sense of smell.
* ThemeNaming: With Steranko. Both have the surnames of classic Marvel Comics artists.
* TronLines: His suit is covered in them.
* VitriolicBestBuds: With Steranko/Rocksteady. [[spoiler: When they're being sucked into a black hole to their deaths, they hold each other so they don't have to die alone.]]
* WasOnceAMan: Is mutated into a warthog both for stealing the Kuro Kabuto helmet and for hurting Karai.
* WeaksauceWeakness: He legitimately is almost as deadly as Rocksteady but [[MotorMouth he just]] [[TrashTalk doesn't know when]] [[YouTalkTooMuch to shut up]] and fight, especially when he's cloaked.
* WhereDoesHeGetAllThoseWonderfulToys: Has an impressive array of high tech gear capable of laser blasts, invisibility, hard light constructs, and special tracking features built into his suit. Where he got the suit is unknown.

[[folder:Kavaxas]]
!Kavaxas
->'''Voiced by:''' Creator/MarkHamill

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/hothead2012.png]]

A powerful supernatural enemy who is brought to Earth by Tiger Claw [[spoiler:to help him resurrect the Shredder, who was killed by Leo in the last episode of the fourth season]].

* ArcVillain: Of the first story arc in the fifth and final season of the show.
* BeamSpam: Can rapid-fire laser blasts from every fingertip.
* BigRedDevil: Kavaxas is a humanoid dragon from Hell.
* BreathWeapon: Can breathe green fire much like [[WesternAnimation/SleepingBeauty Maleficent]].
* CanonForeigner: He was created for the series, though it seems he was inspired by Hothead from the NES version of ''VideoGame/TeenageMutantNinjaTurtlesTournamentFighters''. Michelangelo even calls him Hothead.
* CardCarryingVillain: Proclaims "Now is the season of evil!" when he takes center stage as the BigBad in "End Times" and brings on an apocalypse.
* ComboPlatterPowers: He has SuperStrength, NighInvulnerability, PlayingWithFire powers, is immune to April's PsychicPowers, capable of BeamSpam, and can [[BackFromTheDead raise the dead]].
* CurbStompBattle: His first encounter with the Turtles ends as such in his favor; Kavaxas shrugs off everything they throw at them and forces them to retreat, with Kavaxas only being prevented from pursuing and killing them by Tiger Claw's order to stand down.
* DemonLordsAndArchDevils: Calls himself the "ruler of the netherworld" when Tiger Claw unleashes him. If he is not {{Satan}}, he is this.
* DraconicHumanoid: His face is rather human-looking, but he has red scales, a tail, wings, and fire breath.
* DraggedOffToHell: The [[spoiler: end of "End Times" sees him dragged back to the Netherworld by the Shredder.]]
* TheDragon ([[AccidentalPun No Pun Intended]]): Agrees to become this to Tiger Claw, albeit with a bit of scorn in his voice, when Tiger Claw takes control of the Foot Clan following [[spoiler:Shredder's death]].
* DragonWithAnAgenda: He's ''not'' happy with being forced to obey Tiger Claw, and in "Heart of Evil", he clearly has his own ulterior motives to [[spoiler:resurrect Shredder. Turns out he not only needed to revive Shredder, an evil warrior, but also destroy another warrior, Tatsu, and have Shredder destroy the Seal of the Ancients that Tiger Claw used to keep him in line, allowing Kavaxas to bring about the apocalypse]].
* DragonsAreDemonic: Kavaxas is referred to as a demodragon.
* TheEndOfTheWorldAsWeKnowIt: This mixed with TakeOverTheWorld is in fact Kavaxas's primary goal, and [[spoiler:resurrecting Shredder, an evil warrior, is one of three steps necessary for Kavaxas to have him conquer Earth, with the destruction of a warrior like Tatsu at Kavaxas's hands and the destruction of the Seal of the Ancients the other two steps to raise spirits such as the now-dead Tatsu and Ho Chan to help him overtake Earth.]] Kavaxas is the third villain in this ''TMNT'' continuity to threaten Earth with this trope after Kraang Prime and Captain Mozar and the Triceratons.
* EvilIsHammy: Kavaxas has a very powerful presence and speaks loudly, courtesy of Creator/MarkHamill.
* EvilIsNotAToy: When Tiger Claw summons him, he nearly kills him for daring to try to control him until Tiger Claw produces the amulet that will keep him in line. [[spoiler:Played straight when Shredder is brought back as a zombie under Kavaxas's control and then stomps on the amulet, ending Tiger Claw's control of Kavaxas and allowing him to start the apocalypse. In his debut episode, Donnie's research even states that the ritual to summon Kavaxas has been used for millennia, and every attempt ends in tragedy.]]
* EvilLaugh: Kavaxas gives off several of these kinds of laughs, including when the Turtles visit his lair after he has [[spoiler:resurrected Shredder]].
* {{Expy}}: Seems to have a few things in common with the Tengu Shredder from the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]]. Supernatural demons, dragon theme, and the BigBad of the fifth season.
** Also, Mark Hamill voicing an evil dragon? Hello, [[VideoGame/TheLegendOfSpyro Malefor]].
** He shares a bit in common with Drako from the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]], being a red dragon-like being with some degree of mystical ability.
** He shares a few similarities to Dragon Lord from ''Series/NinjaTurtlesTheNextMutation'', being a DraconicHumanoid who was imprisoned in an EldritchLocation, is too tough to be taken on by the turtles' ninjitsu or their [[TheSmurfettePrinciple token female]][=/=][[TokenSuper super's]] super-abilities and basically replaces the Shredder as the new BigBad after he is indisposed. He even declares that he will eat April and gain her powers when he sees them first hand, something that Dragon Lord declared with the turtle's mutant physiology.
* FlatCharacter: While the rest of the Foot Clan have tragic backstories and {{Freudian Excuse}}s that give their villainous natures a sense of depth, Kavaxas has no real reason to be evil beyond being a Demon-lord, seeking to unleash Hell on Earth for its own sake.
* FourFingeredHands: Kavaxas has four fingers on his claws.
* HoistByHisOwnPetard: The amulet that brought him to Earth and the person who needed his power to be resurrected ([[spoiler:Shredder]]) are the very things that send him back to the Netherworld.
* InSeriesNickname: Mikey dubs him "Hot Head".
* InvincibleVillain: From the minute he's introduced, Kavaxas absolutely ''dominates'' every fight he's in, turning battles from martial combat to just trying to survive long enough to escape. In the end, the Turtles only manage to defeat him by [[spoiler:reassembling the Seal of the Ancients and ordering Kavaxas to go back to the Netherworld.]]
* TheJuggernaut: For all practical purposes, Kavaxas cannot be defeated in a direct confrontation. Even after the Turtles managed to defeat Super Shredder, Kavaxas beats them all despite Tiger Claw forcing him to fight hand to hand. Leonardo hitting him in the face with his swords causes them to shatter to pieces, and April's MindOverMatter doesn't effect him. The ONLY thing that can do ANYTHING to him is the Seal of the Ancients.
* KnightOfCerebus: There is '''nothing''' funny or lighthearted going on whenever Kavaxas is onscreen. He's one of the most dangerous villains in the entire TMNT multiverse and is treated as a very serious threat by the Turtles.
* LegionOfDoom: He forms one of numerous villains the Turtles have faced.
* MyMasterRightOrWrong: He's ''not'' happy about having to obey Tiger Claw, but since Tiger Claw possesses [[RestrainingBolt the Seal of the Ancients]], he has no choice. This also applies to [[spoiler:Michelangelo when he reassembles the seal and orders Kavaxas to end the apocalypse and return to the Netherworld, orders Kavaxas are forced to obey (undead Shredder ensures Kavaxas is sent back).]]
* MultiversalConqueror: As he states in "End Times", he intends to conquer all dimensions.
* {{Necromancer}}: He can revive the dead. Does this with Rahzar, but to revive Shredder he needed his head, heart, and body.
* NighInvulnerability: '''Nothing''' hurts him. Leo's swords [[WreckedWeapon shatter against him]] when he strikes him in the face.
* NoSell: He's immune to April's PsychicPowers, claiming it's because he's not of their reality.
* OmnicidalManiac: If his line to rule all dimensions in a throne of bone and begin an age of suffering, it definitely indicates upon ending all life on Earth, kavaxas will move onto reign death and destruction across the rest of the universe to conquer them all. The fact that his own method of conquering Earth is througha genocidal takeover indicates it.
* OurDemonsAreDifferent: He comes from the underworld and is classified as a demon on the TMNT Wiki.
* OurDragonsAreDifferent: He's a Demodragon.
* PowerParasite: He mentions wanting to devour April and gain her powers.
* PlayingWithFire: As is expected for a demon dragon, he can breathe fire. He can also toss green {{fireballs}}.
* RestrainingBolt: The Seal of the Ancients, a mystical amulet that protects the wielder from Kavaxas's attacks, and also [[MyMasterRightOrWrong forces him to obey anyone who possesses it without question]]. The destruction of this amulet is one of the three steps required to [[spoiler:start the end of the world with Kavaxas in control, but Mikey reassembles it with bubble-gum, reverses that, and forces Kavaxas and Undead Shredder to abandon Earth.]]
* RuleOfThree: He has three objectives he must accomplish on Earth to initiate his own [[TheEndOfTheWorldAsWeKnowIt End of the World]] scenario with him as the ruler. They are, destroy a strong warrior ([[spoiler:Tatsu, the blind swordsman who attempts to take control of the Foot Clan in "The Forgotten Swordsman"]]), revive an evil warrior ([[spoiler:Shredder himself, who was killed by Leo in "Owari"]]), and destroy the Seal of the Ancients.
* SatanicArchetype: He's described as the "ruler of the Netherworld" and the "Lord of the Demodragons", he steals the souls of mortals, and is an expert manipulator.
* SpikesOfVillainy: Kavaxas has spikes on his shoulders.
* TechnicolorFire: His fire breath is green.
* ThisCannotBe: His reaction in "End Times" when [[spoiler:Mikey repairs the Seal of the Ancients with bubble-gum. According to Kavaxas, the Seal was supposed to be unfixable.]]
* WhoDares: His first lines when Tiger Claw summons him:
-->'''Kavaxas''': Mortal! You ''dare'' call upon Kavaxas, Lord of the Demodragons, Ruler of the Netherworld?! I will burn you and the rest of these abominations to ASH!
* WingedHumanoid: Kavaxas has the classic demon wings on his back.
* YourSoulIsMine: Can steal the souls of others, as [[spoiler:Tatsu and the Hammer]] find out the hard way.

%%[[caption-width-right:350:some caption text]]

Founded by Oroku Karai/Hamato Miwa after managing to escape the Shredder's brainwashing, she establishes herself as the new head of the Foot Clan as the Shredder is recuperating and his own Foot Clan are losing territory in New York City. While morally ambiguous, this version of the Foot Clan are allies to the Turtles against the Shredder's Foot Clan. By the end of "End Times", the Shredder is rendered DeaderThanDead and his mutants permanently disbanded, leaving Karai's ninja clan as the only remaining Foot Clan.

* AntiHeroTeam: [[DarkActionGirl Karai]] and [[DarkMagicalGirl Shinigami's]] Foot Clan contrast with the Hamato Clan in many ways. While the Hamato Clan are a FamilyOfChoice and RagtagBunchOfMisfits who only wish to keep their home and their family safe from things that threaten them, Karai's Foot Clan act more like a gang protecting their territory from invading elements they see as a threat. Karai's vendetta against the Shredder (and the many ways she inconveniences him) are [[ItsPersonal entirely personal]]. With this in mind, they are most definitely allies and -- apart from a few hard feelings for past events -- are on the same page.
* PrivateMilitaryContractors: To bolster their ranks, Karai manages to get ahold of a group of mercenaries skilled in ninjitsu.
* RedIsHeroic: While the Shredder's Foot Ninjas and Foot-bots [[DarkIsEvil all dress in black]], Karai's ninjas all dress in Hamato-clan red, representing them as allies of the Turtles.
* RenegadeSplinterFaction: In season four, after the Triceraton invasion is thwarted, Karai starts her own branch of the Foot Clan for the express purpose of taking Shredder out once and for all. Karai's branch of the Foot Clan is allied with the Turtles, and that while she claims that she wants to bring honor to the Foot and make her true father proud, she also desires revenge on the Shredder for everything that he has done.

[[caption-width-right:350:Click [[labelnote:here]]https://static.tvtropes.org/pmwiki/pub/images/kaai3.jpg[[/labelnote]] for spoilers]]
[[caption-width-right:350:[-"C'mon, let me in on the fun."-] ]]

The Shredder's [[DaddysLittleVillain daughter]] who takes over as TheDragon after Bradford and Montes fall out of favor with Shredder. [[LongLostRelative Leonardo bonds with her]] and he desires to see her become good. Little does Karai know that her [[LukeYouAreMyFather entire life is a lie]], as she finds herself becoming a major pawn in the war between the Hamato and Foot Clans.

* AdaptationalBadass: [[spoiler: She is the first version of Karai to be mutated]].
* AdaptationalHeroism: While [[AdaptationalVillainy more prone to morally questionable actions]], she is more capable of disobeying her father than previous versions and, unlike previous versions, [[spoiler: defects from the Foot Clan, only to get mutated and eventually brainwashed back in until Splinter uses his healing mantra to free her, and after the space arc, forms her own version of the Foot Clan that is allied with the Turtles]].
* AdaptationalVillainy: Played with. While she still displays some shades of AmbiguouslyEvil and isn't as bad as her 2003 counterpart after JumpingOffTheSlipperySlope, Karai doesn't really share the NobleDemon shades of her comic book counterpart or her 2003 counterpart pre-JumpingOffTheSlipperySlope, and is much more mischievous than both.
* AdaptationalWeaponSwap: In the comics and most versions, Karai typically uses a katana. Here, she uses a wakizashi.
* AesopAmnesia: [[spoiler: When she learns the truth about what happened between Splinter, Shredder, and Tang Shen, she runs off to pick a fight with Shredder only for Shredder to point out that he taught her everything she knows which results in her getting mutated and later brainwashed. As of season four, Karai has been targeting Shredder's various hideouts and gives it up in favor of going after Shredder himself.]]
* AllThereInTheScript: [[spoiler: Production materials for Karai's snake form call it "Kiba".]]
* AmbiguouslyEvil: Subverted in "The Alien Agenda", where the "ambiguous" part disappears. Played straight again in "Enemy of My Enemy" though, and the end of "Karai's Vendetta". Though she eventually pulls a HeelFaceTurn.
* AntagonisticOffspring: Shredder revealed to Splinter that after their fight, Shredder took Miwa away and changed her name to Karai. However, Shredder told her a different story, reversing his and Splinter's positions, [[spoiler: so Karai didn't realize she's this until seeing the photo of the Hamatos in the Turtles' Lair, which includes her mother. She becomes this in the fourth season after Shredder is put in critical condition.]]
* AntiHero: When she appears in the fourth season, she's no longer under Shredder (either on her own will or [[spoiler:via brainwashing worms]]), and leads a small Foot faction that includes Shinigami; [[spoiler:their goal is stamping out what's left of Shredder's influence in New York after Karai becomes an ally to her real father, Splinter, who had incapacitated Shredder after his attempted BackstabBackfire in "Earth's Last Stand"]].
* AntiVillain: Subverted, [[spoiler: then later played straight: something of a WoobieDestroyerOfWorlds example (she's only evil due to circumstances she couldn't control when she was a baby) with shades of NobleDemon (though as noted below, she's kind of erratic on that).]]
* ArchEnemy: To Leonardo as of "Enemy of My Enemy" and April as of "Karai's Vendetta". Until she finds out the truth later on in season two and, starting with "City At War", it's safe to say they've all patched things up. [[spoiler:She begins treating Shredder as the hateful ArchEnemy she wants dead after she finds out the truth, even retaining her desire to attack him while mutated. It takes until the fourth season for her to finally be able to go after Shredder.]]
* ArrogantKungFuGuy: She is especially this trope in "Karai's Vendetta".
* ArtifactAlias: Even after her identity as Miwa is discovered and she finds out, the Turtles and their allies exclusively refer to her as Karai; only Splinter, her true father, calls her Miwa.
* BadassBiker: In her street clothes and due to having a motorcycle that she drives in "Enemy of My Enemy" and "Karai's Vendetta".
* BadassNormal: She has no special powers beyond her training and no transformations or robotics to enhance her in any way. [[spoiler:Until she is mutated, however.]]
* BackToBackBadasses: Finally works together in a TagTeam with April in "The Insecta Trifecta" to fight off swarms of insect mutants, even helping each other preform combo attacks.
* BerserkButton: [[spoiler:While she doesn't have her mind or ability to even communicate after her initial mutation, she still somehow retains utter hatred of Shredder/Oroku Saki. When confined prior to brainwashing, whenever he approaches her cell, she bolts and tries to attack him. Once she's freed of the brainwashing, her entire goal is getting back at Shredder.]]
** Also, insulting her mother's death is a bad idea too.
* BigRedButton: Apparently cannot resist the urge to press them, as seen in "The Alien Agenda".
* BrainwashedAndCrazy: [[spoiler: She's a victim of this toward the end of season three thanks to the mind control worms. She is however freed of this by the very end of said season and disappears shortly afterward, returning after the "Turtles in Space" arc with Shinigami.]]
* CainAndAbel: She's the Cain to the Turtles' Abel [[spoiler:as she's the biological daughter of Hamato Yoshi/Splinter raised by Shredder]] until she goes through CharacterDevelopment where she learns the truth and goes through a HeelFaceTurn
* CardCarryingVillain: Lampshaded in "The Alien Agenda".
-->'''Raph''': She's ''bad news''!\\
'''Leo''': No, she's not!\\
'''Karai''': Yeah, I am.
* CharacterDevelopment: She goes from being a rather hedonistic and self-serving young lady who relishes in her supposed freedom to being more responsible, serious and composed. It's implied that this was the result of learning the truth on her past meant reevaluating everything she knew along with the horrors associated.
* CoolBike: Uses one in both "Enemy of My Enemy", "Karai's Vendetta", and "City at War", the last one with Shinigami as a co-rider.
* CoolHelmet: A Motorcycle helmet for the aforementioned CoolBike.
* CompositeCharacter:
** As in the 2003 series, Karai has elements of the original Karai from the comics, Pimiko, the Shredder's daughter in the Image series, and Lotus Blossom, a Foot Clan ninja who served as Leonardo's love interest.
** She also shares some similarities with a minor villain from the Mirage comics called the Mistress. Just like the Mistress, Karai is a biological relative of Tang Shen who is manipulated by the Shredder into believing that Hamato Yoshi was the antagonist in their love triangle and the Shredder was the good one.
* TheCorrupter: Tries to be this to Leo. He in turn, [[HighHeelFaceTurn tries to get her to become good.]] In the fourth season, Leo actually joins her Foot Clan for one episode and does stuff like blowing up armories.
* CurbStompBattle: Her fight with April is her giving one of these to her... until April gets her to let her guard down by mentioning her MissingMom.
* DaddysLittleVillain: Shredder is her adoptive father, and he's raised her to be a deadly assassin with a scheming mind.
* DarkActionGirl: She's been able to hold her own against any of the Turtles and has no trouble at all with the Kraang-droids.
* DarkIsEvil: She primarily wears dark colors and makes no secret about how dangerous she is to the Turtles.
* DarkIsNotEvil: Karai continues to wear black even after her HeelFaceTurn.
* DatingCatwoman: In only one episode, she and Leo connected pretty well. Subverted later in "The Alien Agenda" when she betrays Leo and he gives up on her. Shades of this pop up again in "Enemy of My Enemy"... only to end up coming apart at the seams again.
* DesignatedGirlFight: When the Foot Clan starts going on the offensive, Karai singles out April as a viable hostage to use against Splinter and the Turtles, personally trying to kidnap her and even tries to use her as a test-subject for Chrome Dome's lethality. Even after she becomes an official ally to the Hamato Clan, she mocks April for being "weak" and dares her to take her weapon back from Shinigami, though she does eventually apologize in the end.
* DramaticIrony: Karai at one point was trying to kill the Turtles and April. Now, she's helping them, including saving April, who she once considered an enemy from Tiger Claw.
* DeadpanSnarker: Compared to her previous versions, this version of Karai is much more snarky and less serious, willing to snark even in front of her father.
* DecompositeCharacter: Her usual trait from the comics and previous adaptations of coming from Japan to try to take over the Foot Clan in New York after [[spoiler: Shredder's defeat]] is given to Hattori Tatsu.
* DelinquentHair: She wears BoyishShortHair with tails and two tone dye. It goes well with her bad reputation, which she is very proud of.
* DisasterDominoes: Once she discovers the truth about her parentage more than halfway through season two, her life immediately goes downhill, with her being captured twice, [[spoiler:then mutated into a near-mindless creature, then brainwashed as Shredder's loyal servant. It takes until the second half of season four for her to get back on her feet in a meaningful way.]]
* DragonWithAnAgenda: Starting with season two. She's later demoted, much to her chagrin, when Tiger Claw joins the Foot Clan. She was never seen in the episodes between "The Manhattan Project" and "The Wrath of Tiger Claw", so it's unknown if she became TheDragon again.
* EmpoweredBadassNormal: [[spoiler: Gets mutated into a snake creature in "Vengeance is Mine", but the fact that the mutagen was tampered with also allows her to return to human form. Deemphasized, however, as the mental effects, even in her human form, are extreme. She can barely speak. She eventually recovers from the mental effects, though. By the second half of season four, she can shift in and out of the form at will.]]
* EnemyMine: Briefly with the Turtles against the Kraang, but then subverted [[KickTheDog when she takes a broken droid and abandons the Turtles to fight the mutant monster she created.]]
** She does this again in the aptly-titled "Enemy of My Enemy", where she actively seeks out the alliance after learning of the danger of the Kraang. Once again, it doesn't last, but this time, it's the Turtles' fault rather than her own.
* EvenEvilHasLovedOnes: Her true father, Splinter. And despite never having met her, her mother.
* EvenEvilHasStandards:
** When the Turtles betray her trust in "Enemy of My Enemy", she is unsurprisingly disgusted with them for doing so, though she has [[{{Hypocrite}} little room to talk.]]
** In "The Wrath of Tiger Claw", she refuses to harass Murakami, a blind old man, for the Turtles' location.
* EvilCounterpart: To Leonardo, both are the best students of their masters.
* EvilFeelsGood: In her debut episode, she thrives on the freedom being a member of the Foot Clan grants her, and tries to convince Leo that BeingGoodSucks and to just do whatever he wants. When she tries to steal a priceless katana and goad Leo into doing the same, Leo tells her she doesn't have to do such things, to which Karai retorts "[[ForTheEvulz That's what makes it fun!]]"
-->'''Karai''': Don't tell me the goody-three-toes thing doesn't wear thin after a while.\\
'''Leo''': Better than the alternative.\\
'''Karai''': Which is what? To have fun? To cut loose? To live your own life?
* EvilVersusEvil: Briefly against the Kraang.
* FacialMarkings: Are they makeup or tattoos? Who knows.
* TheFarmerAndTheViper: Leo constantly tries to reason with her early on, insisting [[YouAreBetterThanYouThinkYouAre she's not as bad as she claims to be]]. Karai responds by doing such acts as creating a monstrous super-mutant by mistake and ditching the Turtles to clean up her mess and going out of her way to torment and attack both the Turtles and April as RevengeByProxy against Splinter, all while mocking Leo to his face for thinking any different of her.
* FauxAffablyEvil: She was friendly and sociable to the Turtles, but still very much a bad girl. [[spoiler:Following their betraying her trust, she develops a full-blown hatred of them for a while.]] In "Karai's Vendetta", her normally sociable and easygoing personality here only serve to highlight the sadistic pleasure she takes in hunting April. [[spoiler:After discovering the truth about her parents and Shredder, she returns to affable, then Faux Affable comes back when she's brainwashed toward the end of season three.]]
* FightingFromTheInside: [[spoiler:After being mutated in "Vengeance is Mine", she manages to stop herself from killing Splinter. In "Serpent Hunt", her human side is trying its best to resist the reptilian instincts, but it's made clear that she was fighting a losing battle before Baxter Stockman "cured" her and then brainwashed her. She gets better.]]
* FlirtyStepSiblings: [[spoiler:With Leo]], although when they first meet, neither is aware that they are step-siblings.
* FireForgedFriends: With April.
* ForTheEvulz:
-->'''Leo''': Karai, [[YouAreBetterThanYouThinkYouAre you don't have to do this.]]\\
'''Karai''': I know. That's what makes it ''fun''!
* FriendlyEnemy: To the Turtles, at least on her end. [[spoiler: The "friendly" part was cut for a while, though she seems to be rekindling with them after discover that they're practically her brothers. This gets cut again in season three, but brainwashing worms are to blame this time. Finally becomes a semi-ally in the second half of season four.]]
* GreenEyedMonster: Shows signs of it towards April in "Karai's Vendetta", when she angrily demands to know what makes April so special as she's [[NoHoldsBarredBeatdown pounding her into the dirt]]. Her jealousy towards April returns in "Target: April O'Neil", when she's in the middle of [[RoaringRampageOfRevenge trying to kill her to spite Splinter and the Turtles as well as end one of her most hated rivals]].
* AHandfulForAnEye: A signature move she uses often, especially on Leonardo.
* HartmanHips: Karai's butt and thighs are rather large, and often emphasized by her skintight ninja gear.
* HighHeelFaceTurn: [[spoiler: She is the only female villain on the Foot Clan and she finally sides with the Turtles for real after learning that Splinter was her true father all along.]]
* HealingFactor: Revealed to have one in "Broken Foot" [[spoiler:at least when it comes to skin damage, as she heals the burn to the side of her head by performing a mild transformation and "shedding" the damaged skin]].
* HeelRealization: [[spoiler: Feigned believing that Splinter was her true father to get the Turtles to bring her back to their lair. It actually hit when she saw Splinter had a copy of the full picture of Tang Shen and Yoshi, of which she had only ever had the Tang Shen half.]]
* HellbentForLeather: Her street clothes.
* HiddenAgendaVillain: Her actions and expressions during the coda of "The Alien Agenda" indicate she has reasons all her own to make sure the Foot Clan get advanced technology.
* HulkSpeak: [[spoiler: As Kiba. It's a plot point, as she can only give vague clues to where she hides. She can speak normally later.]]
* {{Hypocrite}}: She's not in the best position to criticize the Turtles for betraying her when she had earlier done the exact same thing and showed absolutely no remorse doing so.
** In season one, she remarked that Shredder was "obsessed with revenge". In season two, she becomes bent on taking revenge against Splinter, even disobeying Shredder's orders to do so.
** She stops Shredder from killing a weakened Splinter by claiming it would be dishonorable, except she was the one who fired the tranquilizer dart at him in the first place while he was fighting off Tiger Claw.
* HypocriteHasAPoint: While she has little room to talk when she calls the Turtles out for betraying her trust in "Enemy of My Enemy", she's not wrong in calling them out; Karai was nothing but honest about being untrustworthy in "The Alien Agenda", agreeing with Raph rather than Leo about being "[[CardCarryingVillain bad news]]". She never made Leo any promises ''not'' to betray their alliance, while Leo did with her. Also, it should be noted that after all of the discussion about whether or not to trust Karai, the Turtles are the ones who double-crossed ''her'' this time, not the other way around.
* InkSuitActor: Her facial design and figure is a splitting image of her voice actress Kelly Hu.
* JerkassHasAPoint: While it is true that the Shredder is the Turtles' enemy, in choosing to try and take him out they show that this is more important than their alliance with Karai, which was the source of Karai's disappointment. She thought the Turtles, in particular Leo, was better than that and was willing to work with her against a common enemy and is right to say that Leo was the one who betrayed her this time, not the other way around.
* JerkWithAHeartOfJerk: She seems this way at the end of "The Alien Agenda". Later appearances subvert this and show that she really does have good qualities and that it's just (literally) difficult for her to express them due to her LackOfEmpathy.
** JerkWithAHeartOfGold: She is starting to become a better person now that she knows of her true heritage. Still won't give up her desire for revenge against Shredder though... but has made amends with the Turtles and even April.
* JumpingOffTheSlipperySlope: Starting in "Karai's Vendetta", where following her coming to hate the Turtles, she fully goes from an AffablyEvil FriendlyEnemy to a sadistic and FauxAffablyEvil seeker of vengeance. It only got worse when Splinter became involved, leading her to commit such acts as trying to kill the Turtles and/or April [[RevengeByProxy just to personally hurt him and make him suffer]]. It comes to an end in "The Wrath of Tiger Claw", where [[spoiler:she discovers the truth about her parentage and completely backpedals]].
* KickTheDog: She abandons the Turtles to fight an EldritchAbomination she created, which causes Leo to give up on her...until the next time they met, anyway.
** While her rage against Splinter is understandable and even pitiable since it's a huge lie Shredder has fed her all her life, she certainly doesn't come off too well trying to kill the Turtles or April just to personally hurt him (or settle her jealousy-induced grudge against April).
* LackOfEmpathy: As stated above, she abandons the Turtles even though the EldritchAbomination attacking them was her own fault, and when Leo points out that he trusted her, she mocks him. Then again, she was raised by a full-fledged sociopath, so it isn't very surprising. She moves past this fortunately
* LaserGuidedTykeBomb: Shredder's more or less made her his pawn in his revenge against Splinter.
* LoveMakesYouEvil: A variation. While Karai was always a villain, her hurt at Leonardo's betraying her trust in him prompts her to go from a FriendlyEnemy with a DatingCatwoman type relationship with Leo to a hateful ArchEnemy. Her desire to avenge her mother Tang Shen eventually leads her to conflict with Shredder, [[spoiler: which leads to her mutation into a snake creature and eventually her brainwashing.]]
* MakeUpIsEvil: She has red lipstick and heavy eyeshadow.
* MasterSwordsman: She appears to be as good as Leo, if not better.
* MeaningfulName: Karai means "Weapon". Which is more or less what Shredder is using her as; a means to hurt Splinter, as she's actually his daughter.
** [[spoiler: "Kiba" is Japanese for "fang". Fitting, considering her mutation...]]
* TheMindIsAPlaythingOfTheBody: After becoming a [[spoiler: snake mutant she can't help but see Splinter as prey.]]
* MissingMom: Mentioned in "Karai's Vendetta", which is later revealed to be Tang Shen. Turns out she was told by Shredder that Splinter killed her, when it was in fact the other way around.
* MoralityPet: A twisted example. She is this to Shredder, but he has no qualms of [[AbusiveParents subtly threatening her life]] and kidnapped her from real birth father, Splinter, just out of spite. [[spoiler: However, when she was mutated into a humanoid snake, he showed great anger and sadness, vowing revenge against Splinter and the Turtles for what they did to her. Even though it was entirely ''his'' fault.]]
* MoralMyopia: She called the Turtles out for betraying her even though she betrayed them first.
* MorphicResonance: After [[spoiler: mutating, she retains her snake form's eyes, tongue and teeth when in her humanoid form.]]
* MyGodWhatHaveIDone: [[spoiler: Says this after alerting Tiger Claw to the location of the lair (without the "My God" part) when she realizes that Hamato Yoshi is indeed her real father.]]
* NiceJobBreakingItHero: The pummeling Karai gives to Hattori Tatsu in "The Forgotten Swordsman" leaves him unable to [[spoiler:fight Kavaxas, who steals both his soul and the Kuro Kabuto, two steps to reviving Shredder and starting TheEndOfTheWorldAsWeKnowIt.]]
* NiceJobFixingItVillain: She accidentally creates [[EldritchAbomination Justin]]. Leo even points out it's her fault, [[LackOfEmpathy but she doesn't care.]]
* NiceGirl: Didn't start off this way, but slowly has become one since her HeelFaceTurn.
* NobleDemon: Zigzags on this like all hell. She may occasionally show signs of honor and compassion, but this is interspersed with trying to kill the guys [[SinsOfTheFather for Splinter's (alleged) crimes]] and [[TargetedToHurtTheHero April just to hurt the guys.]]
* OnlySaneMan: Unlike the Shredder, she understands thwarting the Krang's alien invasion of Earth should probably take priority over revenge on the Turtles. Also counts as PragmaticVillainy.
* OutOfFocus: From "Vengeance Is Mine" to "City at War" (roughly two seasons and two out-of-universe years), even though she's still critical to the plot, it's only by virtue of being a plot device with little development on her own following her mutation.
* PetTheDog: She is actually willing to help with no strings attached in "Enemy of My Enemy" and even shares a moment of empathy with April in "Karai's Vendetta" that allows April to escape her.
* PragmaticVillainy: In "The Alien Agenda" in contrast to [[RevengeBeforeReason Shredder]].
* PromotionToOpeningTitles: Her reflection appears in Shredder's mask in the season two opening.
* PsychoticSmirk: She makes one at the end of "The Alien Agenda".
* RaisedByOrcs: Karai was [[spoiler:born the daughter of Hamato Yoshi (later named Splinter after his mutation)]], but she was raised by the Shredder as a member of the Foot Clan, being involved in all of the illegal and dishonorable activity that entails.
* RavenHairIvorySkin: Save for a part of the former that's dyed blonde.
* RealNameAsAnAlias: She goes undercover using the name Harmony. However, "Karai" does not mean "harmony". [[spoiler:"Miwa"]], however, does.
* ReformedButRejected: [[spoiler: Raph is skeptical of her HeelFaceTurn until her mutation.]]
* RedemptionQuest: Starting with season four, she is currently sided with the Turtles and their friends and trying to make up for all the wrongs of the past (even saving April from Tiger Claw in "Darkest Plight").
* RelatedInTheAdaptation: This version of Karai is actually Miwa, the biological daughter of Hamato Yoshi/Splinter.
* RelativeButton: In "Requiem", Shredder declares to her that it's fitting that she should die just as her mother did: in an inferno. Karai promptly flies into a rage and tries to stab Shredder directly in the heart... only for [[spoiler:her blade to [[WreckedWeapon shatter against it]].]]
* RedeemingReplacement: From "City at War" onwards, she and her Foot Clan branch seek to be this to Shredder's own clan. Karai states outright that she seeks to rebuild the Foot Clan under better circumstances and restore its honor after everything Shredder did to pervert it.
-->'''Karai''': I want to rebuild the Foot Clan. Bring back honor to a clan that Shredder poisoned for almost two decades.
* RevengeBeforeReason:
** From "Enemy of My Enemy" onward. While initially pragmatic enough to prioritize trying to stop the Kraang, when the Turtles betray their alliance to attempt to take out Shredder, she flies off the handle and swears revenge on them, to the extent that she doesn't even care about stopping the Kraang anymore.
** Even after her HeelFaceTurn, she falls into it in "Vengeance is Mine". [[spoiler:Karai completely blows off Splinter's words that [[VengeanceFeelsEmpty vengeance only leads to more pain]] and attacks Shredder with the intent to get back at him for everything he's done. It backfires ''spectacularly'' since Shredder taught Karai everything she knows, leading to Karai being captured, used as bait for the Turtles, and ultimately mutated.]]
* RoaringRampageOfRevenge: Against the Turtles as of "Enemy of My Enemy" [[spoiler: up until "The Wrath of Tiger Claw".]]
-->'''Karai''': Our deal's off! You want a feud? [[ArchEnemy You've got one!]]
* RousseauWasRight: Cruelly subverted. Her abandoning the Turtles to a monster she created causes Leo to give up on her.
** Double subverted in "Enemy of My Enemy" where she actively seeks out an alliance with the Turtles, reigniting Leo's hope that there's goodness in her.
* SillyRabbitIdealismIsForKids
-->'''Leo''': I trusted you!\\
'''Karai''': [[LackOfEmpathy I know!]] [[LampshadedTrope That's messed up, right?]]
** This gets turned on its head later:
-->'''Karai''': I thought you were my [[FriendlyEnemy friend!]] [[DramaticIrony How could you betray me!?]]
* SpikesOfVillainy: Downplayed. There's a few small ones on her armor. Her street clothes feature a jacket that has a ton of these.
* SssssnakeTalk: [[spoiler:Post-mutation, any words in English from her are this until "City at War".]]
* StealthHiBye: To Leonardo in "New Girl In Town".
* TheUnReveal: It is never exactly revealed where Karai was between the end of "The Fourfold Trap" and when Raph and April meet her in "City At War".
* TheVamp: She's very privy on using her feminine wiles to get what she wants, especially from males like Leo and Casey Jones who find her attractive. When she undergoes her mutation, she goes straight into SnakesAreSexy territory and even kisses Casey to poison him just for kicks.
* TragicKeepsake: She has a picture of her mother that was actually a photo of both her birth parent with Splinter conveniently cut out of the picture.
* TragicMonster: She was mutated into a snake creature all because of Shredder's carelessness in attacking Leo when he tried to free her from her restraints.
* TokenGoodTeammate: She was this for the Foot Clan before Shinigami came along. Even before her HeelFaceTurn, she was probably the least evil member of the Foot Clan.
* TooManyMouths: In her [[spoiler:snake creature form, aside from her snake arms she also has a mouth on the back of her head.]]
* UnwittingPawn: [[TragicVillain Her entire LIFE]].
* WellDoneSonGuy: In the "Well Done, Daughter!" Gal version. Karai has shades of this beneath her supposedly care-free exterior. Shredder means alot to her and works to make him proud of her, though toned with dark underones given how the Shredder is.
** More tragically, this is the case [[spoiler: with her ''real father'', Hamato Yoshi/Splinter. She's hesitant to join the Hamato and insist tries to redeem the Foot. It's implied that beyond the emotional damage inflicted on her by Shredder, it's the result of her past guilt in warring with them before she learned the truth and possibly her own shame with how she used to be. To further add to the tragedy, Splinter makes it clear that he is already proud of her.]]
* YouAreBetterThanYouThinkYouAre: Leo tried to make her realize this early on, but so far, he [[IgnoredEpiphany hasn't gotten through]]. It takes her finding out the truth about her family for it to sink in.
* YouKilledMyFather: She believes that Splinter killed her mother. Except it's all a lie, and Splinter is her biological father. She is extremely shocked and displeased when she learns the truth.
* YoungerAndHipper: Like April, she's been aged down to 16 years old.

[[folder: Shinigami]]
->'''Voiced by:''' Creator/GwendolineYeo
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shinigamitmntnick_18.jpg]]

A Japanese young woman with dark powers.

* ActuallyPrettyFunny: She admits Mikey regularly makes her laugh.
* {{Animorphism}}: She is able to take on the form of a black cat with a pair of glowing, yellow eyes.
* BadPowersGoodPeople: Shinigami is a witch-ninja with some rather unsettling abilities like hypnosis and transforming into a black cat, yet she is very much an ally of the turtles as a member of Karai's splinter-group Foot Clan and is [[PerkyGoth generally very nice]].
* BladeOnARope: Shinigami uses a kusarigama with a crescent shaped blade and hypnotic stone attached to it as a weight.
* CanonForeigner: She was created for the series.
* DanceBattler: Her combat involves quite a lot of dancing around, though not nearly as often as Bebop.
* DarkIsNotEvil: Despite her Goth/Witch motif and an honorary Foot clan member, she is actually very nice and flirtatious, having allied with the Turtles on various occasions.
* DatingCatwoman: Perhaps taking a cue from Leo, Mikey wants this with Shinigami.
* ExcessiveEvilEyeshadow: Well, it ''looks'' evil at least...
* GamerChick: Is seen playing on a [[spoiler:[[Platform/PlayStationPortable PSP]]]] in her spare time.
* GothGirlsKnowMagic: Shini has a goth look to her that somewhat crosses with Japanese witch traits, and she has a good deal of magic tricks up her sleeve.
* GirlyGirl: Shows signs of this when [[spoiler:Leo]] joins her and Karai on a raid on Shredder's resources. The first thing she does upon seeing ill gotten cash is squeal in delight and exclaim how much they can buy with the money.
* InSeriesNickname: Often referred to as "Shini" by her friends/allies.
* JerkassToOne: Throughout much of her debut episode, Shinigami constantly taunts and toys with April [[ItAmusedMe just for the fun of it]]. Thankfully though, she later [[HeartfeltApology apologizes to April for her actions]].
* KungFuWizard: In addition to her magic tricks and traps, Shinigami is a powerful ninja and nails the Turtles and April the first time they meet.
* LadyOfBlackMagic: An attractive, composed, and feminine kunoichi with magic, summoning bats from shadows and illusory powers to stun enemies.
* TheLancer: [[spoiler:Becomes one to the HeelFaceTurn Karai.]]
* [[{{Ninja}} Kunoichi]]: Karai's right hand [[spoiler:in the Rogue Foot.]]
* NamesToRunAwayFromReallyFast: It means "death god".
* NiceGirl: Ironically, considering her motif, but once you get on her good side, she's actually quite friendly. She's willing to goof off sometimes, and gets along with Mondo Gecko in "Requiem".
* NonIndicativeName: Shinigami means "God of Death". While Shinigami herself is Japanese, she fashions herself after a western style witch rather than an eastern demon. She's not even an enemy, just an old friend of Karai, and generally friendly to the Turtles also.

* PullARabbitOutOfMyHat: Has been seen to pull objects out from her hat.

* RobeAndWizardHat: She wears a witch hat and [[CapeWings a short cape that resembles bat-wings]].

* SupernaturalGoldEyes: Shini has gold eyes and possesses a few supernatural traits.
* TokenHuman: [[spoiler:As of "The Super Shredder", Shinigami is now the only non-{{Mook}}person in the Foot Clan to even be a human; Karai, despite taking a human form throughout, is still a mutant, and Shredder becomes a mutant later on.]]
* UndyingLoyalty: [[spoiler:To Karai, and she is pissed at the Shredder for what he's done to her friend.]]
* VagueAge: It's unclear whether she's a teenager or a young adult.

!Purple Dragons

[[folder:Hun]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/6868faa234a1d0a7db94279b956b9466.png]]
->'''Voiced by:''' Creator/EricBauza

The Purple Dragons' new leader, who makes his debut in the third season.

* AdaptationalComicRelief: Toned down, but the 2003 and comic book versions of Hun were both threatening, serious villains who were usually not played for comedy. This version of the character, while still a formidable foe, is considerably more over-the-top and comically hammy in his Bruce Lee-esque mannerism.
* AdaptationalWimp: This version of Hun is much less of a threat than 2003 Hun was even after his VillainDecay set in. In the fourth season, he's largely there just to get beat up as soon as he appears.
* ArrogantKungFuGuy: He avoids Casey's attacks merely by tilting his head, blocking with his fist, and catching one of Casey's pucks and then proceeds to beat up Casey with regular martial arts.
* BadBoss: When he introduces himself to Casey, he steps on one of the Purple Dragon's face.
* BewareTheSillyOnes: His kung-fu yells may sound over-the-top, but his moves are no laughing matter.
* CurbStompBattle: Effortlessly takes down Casey in his first scene.
* BruceLeeClone: A rare villainous example.
* DecompositeCharacter: He is Hun InNameOnly, while most of Hun's more recognizable characteristics are instead given to Chris Bradford. His name, his clashes with Casey, his status as the leader of the Purple Dragons and him having [[TattooedCrook tattoos]] are the only characteristics similar to the original Hun.
* EvilCounterpart: To Casey. He's an normal human brawler allied with a group mutants and feels he has to prove himself to keep up.
* EvilVersusEvil: Averted. Even though the Purple Dragons were working independently from the Foot Clan in their last appearance, Hun has helped the Purple Dragons re-ally with the Foot Clan. His gang's current allegiance is unknown in the wake of the Shredder's injuries.
* FlatCharacter: He never had much development besides being a hammy BruceLeeClone.
* FunnyBruceLeeNoises: ''All the time.''
* GeniusBruiser: Much like the original Hun.
* GroinAttack: He finishes off Casey by throwing his own puck at him and it looks like he aimed for that particular area.
* InNameOnly: The only similarities this version of the Hun really has with the 2003 and comic book versions of Hun are his name and role as leader of the Purple Dragons, being entirely different in aesthetic, combat, and personality.
* LightningBruiser: Once again, much like the original Hun.
* OutOfFocus: After his introduction, he quickly disappears after "Meet Mondo Gecko". He returns in the fourth season as a minor antagonist.
* RaceLift: Whereas 2003 Hun was originally Caucasian white, this version of Hun is Asian.
* ShoutOut[=/=]BruceLeeClone: His appearance was based off of Creator/BruceLee.
* SunglassesAtNight: He always wears a pair of sunglasses with purple lenses, even when meeting Shredder in the middle of the night.
* TokenHuman: The only one of Shredder's chief lieutenants who is wholly human.
* UnderestimatingBadassery: He doesn't look like much, especially compared to mutants like Rahzar or Tiger Claw, but Casey makes the mistake of underestimating Hun and gets his ass kicked for his troubles.

[[folder:Fong, Tsoi, and Sid]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/Fong_4961.png]]
[[caption-width-right:150:[-Fong-] ]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/Tsoi_794.png]]
[[caption-width-right:150:[-Tsoi-] ]]
[[quoteright:150:https://static.tvtropes.org/pmwiki/pub/images/Sid_7288.png]]
[[caption-width-right:150:[-Sid-] ]]

A trio of thugs who make up the Purple Dragons, a street gang roped into working for the Shredder by Bradford, Montes, Stockman and Steranko. Fong and Sid are both voiced by Creator/AndrewKishino, while Tsoi is portrayed by Creator/JamesSie.
----
* AbandonedWarehouse: Their headquarters is an empty fortune cookie factory.
* AdaptationalWimp: The Purple Dragons are usually a large, city-wide gang that menaces New York in most adaptations. Here, they're just a small group of guys that cause trouble in their neighborhood and commit minor crimes.
* AllThereInTheScript: Only Fong's name has been mentioned on-screen. Tsoi and Sid's names appear in the episode credits.
* BadassCrew: Subverted. They're weaker than the Foot Ninjas and are treated as CannonFodder by the Turtles. They are in the running for the Turtles' least threatening adversaries. This is lampshaded FIERCELY when Hun takes over.
* BigThinShortTrio: Sid is big, Fong is thin and Tsoi is short.
* TheBrute: Sid. He has the largest build of the three, [[DownplayedTrope even if he isn't as tough as he looks]].
* TheCameo: They make one in "Showdown".
* CanonForeigner: They were created for the series.
* DartboardOfHate: A picture of an actual turtle, with a red ninja mask scrawled on it.
* GangBangers: They are the gang "The Purple Dragons".
* GoldfishPoopGang: While they do show up rather often they aren't ever seen as much of a threat.
* {{Jerkass}}: All of them.
* LeanAndMean: Fong is extremely gaunt.
* {{Mooks}}: They are weaker than Foot Ninjas, and thus make better cannon fodder.
* OddlySmallOrganization: We have never seen that many Purple Dragons despite being a prominent street gang.
* OutOfFocus: After Bradford and Montes got mutated, they started to appear less and less, until eventually making an unvoiced cameo in "Showdown". The only roles they take in season two were a brief fight with Casey in "The Good, the Bad, and the Casey Jones", and function as Steranko's artifact retrievers until he got mutated, and then as Ho Chan's henchmen in "A Chinatown Ghost Story", but then [[WhatHappenedToTheMouse abruptly disappear from the plot]] after being asked about Ho Chan when he throws them away.
** Even in "Casey Jones Vs. the Underworld", they only appear in the opening.
* PetTheDog: In "Never Say Xever", Fong hands Leonardo his out-of-reach Katana blades as a reward for showing mercy when he was fighting him, to help defeat Xever and save Murakami.
* RousseauWasRight: [[spoiler: When it look like Xever, Bradford, and the Foot Ninjas have the Turtles beat, Fong tosses Leo (who had let him go earlier) his sword, [[TheDogBitesBack though it was possible he did it to get back at Xever for knocking him around]]]].
* ShameIfSomethingHappened: They're introduced trying to extort Murakami, and a later episode reveals they have to pay tribute to the Shredder, presumably for the "privilege" of operating under his name.
* {{Tattooed Crook}}s: Like most stereotypical gang members.
* TerribleTrio: Subverted. They're a trio of bad guys, but they lack the needed individuality that comes with this trope, all having more or less the same personality.
* TookALevelInBadass: They're granted powers by Ho Chan in "A Chinatown Ghost Story", which makes them more effective. While tougher, the Turtles take them down with as much difficulty as an average mutant. Ho Chan then removes their powers out of annoyance for the shoddy performance.
* TheTriadsAndTheTongs: They all appear to be Chinese.

!Foot Soldiers and Other Associates

[[folder:Koga Takuza]]

The founder of the Foot Clan, he's well known in Japanese history for the group's creation. He was also responsible for the creation of the Kuro Kabuto.
----
* CanonForeigner: He was created for the series.
* GreaterScopeVillain: Downplayed; while he is the founder of the Foot Clan, it's unknown if he and his clan were truly villainous before eventually Oroku Saki took control in the present day.
* {{Ninja}}: One of the first in the Foot Clan.
* PosthumousCharacter: Having founded the Foot Clan before they were wiped out and the Kuro Kabuto being an heirloom, this is most likely his status.
[[/folder]]

[[folder:The Foot Ninjas]]
[[quoteright:145:https://static.tvtropes.org/pmwiki/pub/images/foot-w145-h275_7914.png]]

The openly acknowledged CannonFodder of the Foot Clan.
----
* AdaptiveAbility: "Follow The Leader" introduces us to [[MythologyGag robot Foot Ninja]], who catch on to a person's attack pattern as a fight goes on.
* AdaptationalBadass: The Footbots seem to be far more dangerous and powerful here due to their AdaptiveAbility, whereas they were just CannonFodder in the 1987 series.
* BadassArmy: Subverted, then played straight upon the introduction of the Foot Bots.
* CannonFodder[=/=]{{Mooks}}:
* CoolMask: With almost bug-like eyes, like most versions of the Foot Clan.
* DarkIsEvil: Mostly black, fitting their role as stereotypical ninjas.
* FacelessMooks: They are never seen unmasked, and the robotic foot wouldn't have a face aside from their "masks" any way.
* IneffectualSympatheticVillain: And lampshaded by the Turtles in "Pulverizer Returns". Justified because it turns out that most of them are not properly trained ninjas but rather just anyone the Foot Clan can find and recruit.
* {{Kiai}}: Robot Foot Ninja constantly shriek in small bursts.
* MalevolentMaskedMan: As mentioned they are malevolent and are never seen without wearing their masks.
* MechaMooks: Shredder eventually runs out of properly trained Foot Ninjas, as they've all been arrested, badly injured, or just flat out quit. As a result, he ends up trading out to the Footbots in season two, which are far more expendable.
* MultiArmedAndDangerous: Some Footbots have these.
* {{Ninja}}: They serve as this for the Foot Clan.
* RedAndBlackAndEvilAllOver: Their primary color scheme.
* RedEyesTakeWarning: The lenses on their masks are red.
* ReplacementMooks: Season Two replaces the human mooks with robots who are far more powerful than the previous ones.
** And AGAIN in season four, with the ELITE Footbots!
* VillainDecay: In their debut appearance, the Footbots give the Turtles a lot of trouble, mostly due to their AdaptiveAbility. But over time, they became just as ineffectual as the human Foot Ninja were, with said AdaptiveAbility seemingly non-existent.
* TheVoiceless: Aside from the robotic foot's monkey-like shrieks.
* WeHaveReserves: {{Deconstructed}}: Shredder is largely unconcerned with throwing his troops at the turtles no matter how many that get beat up...which results in him running out of trained ninja and having to resort to grabbing anyone they could recruit. Turns out people with years of training aren't expendable.
* WhatHappenedToTheMouse: What happened to the human soldiers once Shredder replaced them with the robots is never seen or mentioned.
[[/folder]]

[[folder:Shredder mutants/Mega-Shredder]]

* AdaptationSpeciesChange: They're hybridized mutants rather than just human clones with bizarre traits.
* AttackOfTheFiftyFootWhatever: [[spoiler: They become a giant monster after falling into a tank of mutagen.]]
* BodyHorror: [[spoiler: Another set of them is dumped into a vat of mutagen and they are fused together to form a giant horrifying monster that attacks New York.]]
* FamilyUnfriendlyDeath: They are all killed in graphic ways (one of whom was pushed into a fan) by Splinter.
* GiantEnemyCrab: Each of the Shredder mutants appear to be based on a crustacean. Mini-Shredder a shrimp, Claw Shredder appears to be based on more of a lobster, and judging by the shell on its back Shiva-shredder may just be a crab.
* MythologyGag: The Shredder Mutants were originally from the Mirage Comic storyline "Return To New York" in 1989, and also appeared in the 2003 adaptation of the story.
* MultiArmedAndDangerous: Shiva-Shredder.
* PragmaticAdaptation: The three's nature as hybrid mutant clones of the Shredder being created by Stockman make more sense here, due to the Foot Clan coming off as largely traditional before their team up with the Kraang.
* RentAZilla: [[spoiler:As the Mega-Shredder.]]
* ShoutOut: Shiva-Shredder has a lot of resemblance to [[Franchise/MortalKombat Goro]], though the character predates Goro by several years if you go by his original comic version.
* UnderestimatingBadassery: The Turtles underestimated Mini-Shredder due to his height and obviously being (quite possibly) a mutant shrimp. They quickly learn that was a mistake.

[[folder:Chrome Dome]]
[[quoteright:145:https://static.tvtropes.org/pmwiki/pub/images/chromedome-w145-h275_6523.png]]

An upgraded robotic foot ninja created using Chris Bradford's armor, first sent out to hunt down April.
----
* AIIsACrapshoot: Created for Karai to destroy April, but the Kraang put in an override program to capture her instead. It later malfunctions, and starts trying to destroy everyone in sight instead.
* EliteMooks: In the fourth season, [[spoiler: the Chrome Dome design is improved upon and mass-produced.]]
* EnergyWeapon: Whips, chucks, and [[LaserBlade swords]].
* EyeBeams: Uses these to bisect the [[DeadlyDisc manhole covers]] shot at it by the Shellraiser.
* {{Flight}}: Via RocketBoots.
* ImpaledWithExtremePrejudice: Defeated when Mikey impaled it with its own LaserBlade, and later again by Karai.
* KingMook: Far more advanced than the Footbots, and based on Bradford's old armor instead of the standard Foot uniforms. It gives the team a hell of a fight.
* MythologyGag: Named after Chromedome from the 1987 series.
* PaletteSwap: It's pretty clearly the human Bradford in his ninja garb, but with some minor alterations in color and proportion.
* RobotMe: Of Bradford, pre-mutation.

[[folder:The Foot Cultists]]
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/foot_cultists.png]]

Creatures from the sewers who have complete loyalty to the Shredder and [[spoiler:assist Tiger Claw and Kavaxas in their quest to revive Shredder in the fifth season. What started as a fight between Splinter and Super Shredder caused some of the latter's mutagen to leak into the sewers where a hobo touched the mutagen and mutated into the first Foot Cultist and soon spread the effect to other people, all with Shredder's memories.]]
----
* AndThenJohnWasAZombie[=/=]AsteroidsMonster: Ordinary people touching Super Shredder's mutagen is what makes them multiply.
* CanonForeigner: They were created for the series.
* {{Cult}}: They're more or less the Cult of Shredder and literally worship him.
* {{Expy}}: With the reveal that they were [[spoiler:New York sewer-dwelling homeless people mutated into {{Humanoid Abomination}}s by toxic waste (in this case Super-Shedder's mutagen-infused blood)]], they are a reference to the monsters from ''Film/{{CHUD}}''.
* InvincibleMinorMinion: These monsters are the toughest terrestrian mooks the Turtles have fought up to the fifth season, able to catch the Turtles' weapons and survive long falls.
* ReligionOfEvil: The Foot Cultists are devoted solely to Shredder and Tiger Claw, worshipping the former.
* WeakenedByTheLight: For all of their combat abilities, bright light is enough to keep them away.
* WhatHappenedToTheMouse: The Foot Cultists are never seen again after Fishface chases them off with the light of his lantern. There is no mention of what happened to them after Kavaxas and Shredder are send back to the Netherworld and Tiger Claw forms a truce with the Turtles, nor are there any plans discussed to [[spoiler:change them back into regular people]].

->'''Voiced by:''' Creator/MichaelHagiwara

A swordsman who comes to New York [[spoiler:after Shredder's death to recover the Kuro Kabuto and take over the Foot Clan]].
----
* AdaptationalBadass: Compared to his live action movie counterpart, this version of Tatsu proved to be far more dangerous.
* AntagonistTitle: Tatsu is the titular character in "The Forgotten Swordsman".
* BackForTheDead: [[spoiler:His spirit returns along with sorcerer Ho Chan to attack one half of the Hamato Clan's forces in "End Times". Unlike Ho Chan, who had to be confronted by Splinter's spirit, Tatsu's spirit is quickly disposed of by April, Casey, Donnie, and Raph.]]
* BigBadEnsemble: He tries to form a Foot Clan separate from Tiger Claw's by claiming the Kuro Kabuto. [[spoiler: Too bad he was killed off in his first episode]].
* BigBadWannabe: He had all the making of being a powerful BigBad, and was one of the Turtles' deadliest foes. Unfortunately, [[spoiler:Kavaxas proves to be more dangerous, and Tatsu was quickly killed by the demodragon within seconds]].
* BlindWeaponmaster: See HandicappedBadass below.
* CanonImmigrant: He is a character who was introduced in the 1990 live-action film, and makes his animated debut here.
* CompositeCharacter: He is derived from the 1990's film character, as the Shredder's right hand man who tries to take control of the Foot Clan [[spoiler: following Shredder's defeat]]. This also brings forth traits from previous versions of Karai, as he comes from Japan to try to take over the New York Foot Clan.
* DisabledInTheAdaptation: Tatsu was of clear sight in the 1990 film, but is blind in this adaptation.
* TheDragon: He mentions that he was once the Shredder's right-hand man back in Japan.
** Not to mention, his name also means "dragon" in Japanese.
* DragonAscendant: He's gunning for this, [[spoiler: trying to start a new Foot Clan in the wake of Shredder's death. Tiger Claw, however, has a trump card in Kavaxas.]]
* EvilLaugh: Gives off a pretty good one when he returns [[spoiler:as a spirit in "End Times".]]
* EvilerThanThou: For all of Tatsu's skills, [[spoiler:he is hopeless against Kavaxas when the demodragon plays this trope on him, though Snake Karai having pummelled him through bites did not help his chances of not being killed by Kavaxas.]]
* HandicappedBadass: Tatsu is blind, but one of the best swordsman in the world.
* LogicalWeakness: Tatsu relies on his sense to compensate for his blindness. Leo and Karai take advantage of this by setting off several explosions using Casey's pucks and attacking while he is vulnerable.
* MythologyGag: He uses a sword in this adaptation. His original actor, Tobishiro Obata, was a professional swordsman.
* NamedByTheAdaptation: This Tatsu is given a first name, Hattori.
* SoLastSeason: The guy is basically a SuspiciouslySimilarSubstitute to the [[spoiler: pre-mutated Shedder]]. While he still manages to beat down the Turtles and their allies in the same manner as Shredder, they were able to defeat to him in the end, showing how much stronger our heroes have gotten. After his defeat [[spoiler: he is shortly killed off by the true main threat of the fifth season]].
* TheyKilledKennyAgain: [[spoiler:[[DownplayedTrope Downplayed]], as he never really comes back to life, he just returns as a spirit. But he is destroyed in both of the only two episodes he appears in. The first time, as a human, and then again as a spirit a couple episodes later when he tries to attack the Hamato Clan.]]
* TooPowerfulToLive: Tatsu is easily as powerful as Shredder himself, mopping the floor with the Turtles, Karai, Shinigami, and Bradford and Xever. [[spoiler: He's quickly killed at the end of his first episode.]]
* WeCanRuleTogether: He offers Bradford a place in his new Foot Clan as his second in command, and is notably the only member of the Foot Clan that he encounters who is granted such kindness. Bradford refuses, deciding to remain loyal to the Shredder.
* WeHardlyKnewYe: [[spoiler: Kavaxas takes his soul at the end of his first episode.]]
* TheWorfEffect: He shown to be as strong as the [[spoiler: pre-mutated]] Shedder, and was to able fight off the Turtles, Karai, Shinigami, April and Casey. However, [[spoiler: he was quickly killed off by Kavaxas, just to show how much more dangerous the demodragon is in comparison. Granted, thanks to Karai, he was already injured when he was confronted by Kavaxas]].
* YourSoulIsMine: [[spoiler:He's the victim of this trope courtesy of Kavaxas.]]

!The Vizioso Mafia

[[folder: Don Vizioso]]
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/don_vizioso.jpg]]
->'''Voiced by:''' Creator/BrianBloom

TheDon of New York's Italian mafia, who agrees to fold to the Foot Clan. After Shredder is put on life support halfway through the fourth season, Vizioso, now no longer affiliated with the Foot Clan, attempts to take control of the city's crime business.
----
* AdiposeRex: He's a grossly obese gang lord who controls enough turf that Shredder meets with him personally to bring him to heel.
* AffablyEvil: Pretty cordial with Shredder, and once he joins the Foot Clan, affably asks how he can be of service to the Shredder.
* ArchEnemy: Donnie regards him as this due to his bigotry against mutants and attempting to vivisect him.
* BigBadEnsemble: In Seasons 4-5. With the Shredder incapacitated and later dead, the Don steps up to make his bid for power separate from Shredder's Foot Clan.
* BigBadWannabe: This trope was even in effect before he became an independent villain. Shredder was quickly able to scare him into submission in season three. His later attempts to take control of New York's underbelly in Seasons 4 and 5, while still dangerous, are no match for the Hamato Clan when it comes down to it.
* BigEater: He is never seen ''not'' eating something, usually in massive portions.
* CanonForeigner: He was created for the series.
* CrazyPrepared: His chair in his restaurant turns out to be a jetpack chair, which he uses to attack and escape the Turtles and Mutanimals when they confront him.
* TheDon: Obviously. In Season 4 he starts getting addressed as "the Don" by the heroes.
* EvilVirtues:
** Camaraderie. As much of a slob and a prick he is, it's pretty clear that his subordinates genuinely respect him (unlike the Shredder, who rules over his minions with fear).
** Patience. While it is clear that he hates being under the Shredder's thumb, he's smart enough to kiss his ring (metaphorically speaking) and stay out of his way, waiting it out until the Shredder is out of the way before going back to running the streets.
** Resourcefulness. Despite being an old-fashioned gangster in an age of mutants, aliens and ninjas, Vizioso is shown to be good enough at old-fashioned crime that he was still able to remain active in New York, finding opportunities in the fallout of the Kraang invasion possessing the right contacts and resources to create a weapons to fight against mutants.
* {{Expy}}: He's more or less the show's answer to [[Franchise/StarWars Jabba the Hutt]]: an obese, disgusting gang lord antagonist who even revolts the BigBad.
* FantasticRacism: He despises mutants enough that he arms his men with anti-mutant weaponry.
* FatAndProud: Implied, he's got a big fancy painting of himself practically nude in his dining room, suggesting he's very proud of and enjoys his colossal size as a symbol of his wealth and power that's gotten him so fat.
* FatBastard: Casually remarks that the devastating Kraang invasion has brought new opportunities for gang lords like him and the Shredder, and is also hugely fat.
* FatSlob: Definitely, he has horrible table manners.
* ImAHumanitarian: [[spoiler:It's implied that he plans to eat Shredder's heart, believing it would give him his powers.]]
* JabbaTableManners: He's got atrocious manners, and even spits up a meatball he hadn't chewed before speaking to Shredder.
* KnowWhenToFoldEm: One quick gesture from Shredder regarding a sliced meatball is all it takes for Vizioso to cede control of his empire to Shredder. When his favorite leg-breaker is coldly and messily killed by a Satanic demon, he decides to give up on New York and move his operation back to Italy.
* MythologyGag: Seems to be based on the 80's character Blobfather, though he never mutates and his blob nature remains because of his fat.
* ScrewThisImOuttaHere: After Kavaxas [[spoiler: kills the Hammer and deals his mob a nasty defeat,]] Vizioso decides to move his operation to Italy and leave New York for good.
* SmallNameBigEgo: Downplayed. The Don thinks he's a huge, intimidating threat, but he's really only just huge for the most part. He's cunning and powerful enough to run a normal mafia in a city of aliens and mutants, but he's ultimately no match for the powers that be despite his ego.
* TrademarkFavoriteFood: Being an Italian-American Mafia don, he has a predisposition towards Italian Food, stuffing his face with spaghetti, calzones, Italian sausage, etc.
* UnusuallyUninterestingSight: While the rest of the city is still recovering from the Kraang invasion and mass mutation, Vizioso has brushed himself off and gone right back to ruling the mob. He's also pretty unfazed by having to deal with a mass-murdering ninja master and his army of robots and mutants. He finally reaches his limit in Season 5 when the powers he's dealing with get too occult and dangerous, and he decides to head back to Italy.
* VillainousGlutton: He's always seen eating, be it a large table of Italian food, or an endless stream of concession snacks and takeout.
* VillainousWidowsPeak: He's got one.

----
* AlwaysIdenticalTwins: This are no differences for these identical twin brothers.

A bombastic heavy-hitter for the Visioso mafia.
----
* CanonForeigner: He was created for the series.
* CharacterCatchphrase: "Hey-yo"
* FamilyUnfriendlyDeath: His death at the hands of Kavaxas is not a pretty one, as evidenced by a shot of his body afterwards.
* KilledOffForReal: His soul is drained from him by Kavaxas in "Heart of Evil"
* NoNameGiven: He is never referred to by his real name.
* NoCelebritiesWereHarmed: He looks (and sounds) alot like Creator/SylvesterStallone.
* NotQuiteDead: He is crushed by a chandelier in "Heart of Evil", but is later shown to have survived. However, he later is actually killed in the episode.
* YourSoulIsMine: Loses his life via this trope to Kavaxas in "Heart of Evil" the same way [[spoiler:Hattori Tatsu]] did one episode earlier.
