The Turtles and Splinter

The main heroes group. The TMNT with their master, Splinter.

    open/close all folders 

     As a whole 

  • Badass Family: Undeniably so, as they regularly fight off hordes of aliens, monsters, and maniacal humans.
  • Bald of Awesome: The Turtles by virtue of being hairless reptiles.
  • Brains and Brawn: Don and Raph
  • Color-Coded Characters: In the Mirage comics, the Turtles all wore red bandanas (not that it mattered much in a black-and-white comic), leaving their distinct weapons as usually the best way to tell them apart. The series follows the 1987 choice of give Leonardo blue, Donatello purple and Michaelangelo orange, while Raphael kept red. Lampshaded in Turtles Forever when the Mirage Turtle call "silly" both the 1987 and 2003 versions for this. For the first time, their weapons as well as their bandanas have their individual colors.
  • Divergent Character Evolution: While not as extreme as subsequent adaptations (which give them more overtly different body types and design quirks), the show follows the earlier 1987 toys and 1990s videogames in having each turtle in different shades of green.
  • Happily Adopted: The Turtles love and respect Splinter as if he were their real father and outright call him "father" regularly. This bemuses the 1987 Turtles, who do not see Splinter as a father figure in the same sense that these Turtles do.
  • Know When To Fold Them: The Turtles sometimes invoke this, with Raph on one occasion settling on a "tactical retreat". This is also the Ancient One's first lesson, when a bitter Leo faces a losing battle against intangible demons.
    Leo: To surrender is not the warrior's way!
    The Ancient One: You won't be much of a warrior without a head!
  • Metamorphosis: From turtles to humanoid turtles, and from a rat to a humanoid rat.
  • Named After Somebody Famous: They are all named after iconic Renaissance artists.
  • Ninja: They are a clan of ninjas.
  • Le Parkour: And roof hopping as they are real urban ninjas.
  • Red Oni, Blue Oni: Raph and Mike are Red, Leo and Don are Bluenote  This often shifts with their personalities as Raph is Hot-Blooded and has a bad temper while Leo keeps a cool head and is serious about keeping things in order. Mikey likes to fool around a lot and is a prankster while Don is more into technological advancements and is way more focused on his duties than Mikey.
  • Trademark Favorite Food: Averted in this series. Direct references to pizza are intentionally few and far between across the seven seasons, and they often mention eating ice cream, Chinese food, hot dogs, and various other foods. However, pizza is still the most potent health item in most video games based in this continuity.
  • Undying Loyalty: To each other.
  • Unusual Euphemism: They often use the word "Shell" in the place of the word "Hell". Which often leads to some pretty corny one-liners.
  • Weirdness Magnet: Noted several times:
    Michelangelo: How come all the weird stuff always happens to us? I mean, we were just minding our own business, when WHAM, that time lady fell out of the sky, right on top of us! Now we're stuck here AND we've gotta go to that creepy-looking place! It just doesn't seem fair!!!
  • Would Hit a Girl: The Turtles have no problems with attacking Karai, although to be fair, she is more than capable of holding her own in a fight.


The leader, always in control. In this version, he is more well-balanced and serious than in the 1987 TV series and first three films. He spends the most time training and takes the Bushido code of honor to heart, mentioning it several times within the show. As the responsible one, he usually tries to stop his brothers from going on crazy missions (without Splinter's permission) before getting dragged into it himself. Like the Mirage comics and the film pentology, Leo and Raphael have disagreements constantly, particularly in the City at War trilogy.

  • The Ace: Becomes arguably the most skilled of the four brothers due to also spending a lengthy amount of time training under the Ancient One, and was the first of the Tribunal's warriors to manifest a dragon avatar.
  • Authority Equals Asskicking: Consistently the most skilled Turtle, he falls into the leadership role by default.
  • Big Brother Instinct: Even though he's never officially stated to be the oldest he definitely acts like The Leader which makes him fiercly protective over his family.
  • The Chains of Commanding: Michelangelo notes this in "Samurai Tourist", that Leo takes the burden of being the leader so his brothers can do what they want: Dontaello's free to pursue his technological inventions, Raphael's free to let loose and fight, and Mikey's free to just relax because their brother's in control.
  • Character Development: Really beautifully put into the mix in season 4 where he becomes the best fighter of the bunch while trying and failing to master his anger and fear after being defeated and stabbed in season 3 before finally reverting to his original personality.
  • Cultured Warrior: If one of the turtles is going to be in touch with Japanese traditions, it's gonna be Leo.
  • Deconstruction: In "Samurai Tourist", Mikey — yes, Mikey — gives an accurate analysis as to why Leo takes the burden on being the leader: so that he lets his brothers be themselves.
    Mikey: I think you all [Donatello, Raphael and Casey] should just lay off the poor guy [Leonardo]. I mean, it can't be fun always being the responsible one. And we're the ones who really benefit: Raph's free not to think cause Leo does all the thinking for him, Don's free to dream, and I'm free to take it easy all because Leo's busy being responsible enough for all of us.
  • Determinator: Even when he's up against an impossibly powerful enemy, Leo won't give up until he's unconscious or worse.
  • Dual Wielding: He always wields two swords, and if one is broken he still fights with the other one.
  • Emotions vs. Stoicism: A lot of what he puts up with has him wondering if he should fight or remain still.
  • Heroes Prefer Swords: As the leader of the group, Leo gets the shiny swords.
  • Heroic BSoD:
    • After being ambushed by the entire Foot Clan and being easily defeated by the Foot Elite, and his family being forced to evacuate New York after April's home is destroyed, Leo falls into a state of depression. Raph is able to help him get out of it by training him to get back into fighting shape, and by forging a new pair of swords.
    • After the Turtles and Splinter are forced to commit suicide to stop Shredder in "Exodus", Leo is traumatized, feeling that because he wasn't good enough, his family had to kill himself. He remains in this funk for most of Season 4, before training with the Ancient One helps him learn that he isn't at fault for not being able to do anything else.
  • He’s Back: Happens to Leo twice: First during "Return to New York", when he confronts the Foot Elite which nearly killed him during their first encounter, and again in "Prodigal Son", the conclusion to his season 4 character arc.
  • Heterosexual Life-Partners: With Miyamoto Usagi.
  • Katanas Are Just Better: Obviously. Although Leonardo's swords are often much more closely modeled around the ninjato.
  • Knight Templar: Leonardo's story arc in the 4th season have him nearly cross over into Knight Templar territory. His rage gets so bad he actually wounds Splinter and has to be sent away to Japan to learn from Splinter's master.
  • The Leader: Has been a born leader ever since he was a child showing great skills as one, the opening explains it perfectly. "Leonardo, always in control."
  • Master Swordsman: He uses his katana very skillfully.
  • My God, What Have I Done?: Leonardo has an example of this in "The Ancient One", when he loses control and injures Master Splinter. The look on his face after it happens and his subsequent remorse show he was clearly shocked, and deeply regretted his actions.
  • No-Holds-Barred Beatdown: He gets into quite a few of these. If he's not on the receiving end, he's usually administering it.
  • Not So Above It All: Despite being the serious one, Leo's not above having fun and joking with his brother's when he gets the chance.
  • Red Oni, Blue Oni: The blue to Raphael's red, in terms of their headbands and in personality.
  • Samurai: Leonardo is technically a ninja, but a lot of the tenets he quotes are in line with samurai. It's no surprise he and Usagi got along swimmingly.
  • Sanity Slippage: After his devastating injuries when he fought the Shredder, Leo is increasingly losing his cool by the minute and is pushing himself way too far and goes as far as to almost harm his family. He does this to Splinter when he is frustrated during his training in an Unstoppable Rage.
  • Scars Are Forever: To an extent. In the Season 3 finale, the Shredder breaks off part of his upper shell. All throughout Season 4 the crack in his shell remains as he descends into Knight Templar territory, and even after he recovers it refuses to heal. Not until the Fast Forward reboot, anyway.
  • Sliding Scale of Idealism vs. Cynicism: He starts out at the very end of the Idealism scale, even believing the best of the Shredder and then his daughter Karai. As the seasons progress he shows signs of being capable of sliding down the other way — he does this in the fourth season — though he remains mostly rooted in idealism.
  • The Spartan Way: Leonardo as a child was suffering from a fear of heights. Splinter brings him to the top of a gigantic reservoir and pretends to be in danger of falling. Leonardo forces himself to crawl out and save him, and apparently conquers his fear in the process.
  • Strong and Skilled: By far Leo is the most proficient ninja out of all of his brothers who are either Skilled, but Naïve, Unskilled, but Strong, or Weak, but Skilled.
  • Took a Level in Badass: In the first season he can barely handle fighting one of the Foot Elite, and is nearly killed trying to take on all four. By the end of the fourth season, he not only takes on all four without apparent difficulty, but also bests Karai, the incumbent Shredder, in the process.
  • Took a Level in Jerkass: During the first half of the fourth season, combined with Heroic BSoD from his devastating failure and his now present Hair-Trigger Temper. He gets over it after training with the Ancient One.
  • Unstoppable Rage: During the fourth season when he wounds Splinter while he is overcome with grief and anger. He continues this when he is sent to train with the Ancient One and during his travels he succumbs to his wrath once more against a pair of giants.
  • Weapon of Choice: Twin Katana. He briefly takes on Feraji's sword in mid-season 5.
  • What the Hell, Hero?: In a reverse from usual situation, Raph calls Leo out in 'The Ancient One' for injuring Master Splinter when Leo loses control in a fit of rage.
    Raphael: Leo, what the shell is your problem?!
  • Wrecked Weapon: Done to Leonardo's swords in the episode "The Shredder Strikes Back, Part 1", as the climax to the ass-kicking the character gets in that episode. And again in "Big Brawl, part 1" by a Gom-Tai.

Raphael's personality in this adaptation is more like his Mirage counterpart; he is angrier and more sardonic, but not quite as violent (although he is still impulsive). Count on him to throw the first punch. One incident emphasising his quickness to anger is where he almost smashed Michelangelo's head in with a pipe is shown here. In this adaptation, Raphael speaks with a similar Brooklyn accent used in the movies.

  • Aloof Big Brother: Partially inverted. He's younger than Leonardo making him an aloof little brother, but older than Donatello and Michelangelo, playing it straight for them, as he has more of a harsher personality and has a lone wolf mentality whenever he is feeling pressured.
  • Badass Biker: He is shown to be a skilled motorcyclist and has his own motorcycle, the "Shell Cycle".
  • Bash Brothers: With the rest of his brothers. Along with Casey as well.
  • Berserk Button:
    • He loves his bike and quickly turns to rage if anyone messes with it.
    • Did we mention how much Raph hates bugs? In "April's Artifact", he gets pushed too far after recovering from the paralysis given to him by one of the hornets, declaring in a Punctuated! For! Emphasis! fashion that bugs must pay.
  • Big Brother Bully: To Mikey, especially when his younger brother annoys him and he won't hesitate to teach him a lesson.
  • Big Brother Instinct: When a beaten and battered Leo is tossed tbrough the window, Raph's first instinct is to go hunt down who did this to his brother.
  • Big Damn Heroes: In the "City At War" arc (with some help from Splinter).
  • The Big Guy: The most aggressive and probably strongest member.
  • Brooklyn Rage: Not only because he's an angry New Yorker — the first movie even gives him a Brooklyn accent.
  • Catchphrase: "I got your X right here." and also "You and me are having words."
  • Driven by Envy: Downplayed. Raphael appears to live in the shadow of Leonardo and resents his brother's social position in the group. However, though at times he may seem quite jealous of Leonardo, Raphael's rivalry with him is heavily toned down in comparison to the comic books, and Raphael rarely shows a deep hatred towards Leo as the series progresses.
  • Fire-Forged Friends: With Casey, as they originally came to blows numerous times when they first met. However, facing off with the Purple Dragons not only integrated Casey into the Turtles' family, but solidified their friendship.
  • Hair-Trigger Temper: Especially early on in the series where he was very quick to anger as his spar with Mikey shows he had trouble controlling his temper when he is enraged.
  • Hot-Blooded: Raphael has a very fiery temper and a determined willpower and will often be the loudest of the turtles approaching Boisterous Bruiser territory especially with this quote in the opening. "Count on Raphael to throw the first punch!"
  • Jerk with a Heart of Gold: He's more abrasive than the others, but is still as noble as the other Turtles.
  • Jerkass Has a Point: Raph's attitude during the "City at War" trilogy. What the Hell, Hero? stems from the fact that he refuses to believe that the Turtles were responsible for New York's gang war between the Foot Clan, Purple Dragons, and the Mob and he sounds like he doesn't care about the innocent people who have been caught in the crossfire. This stems from his statement that the Turtles' involvement would only "add fuel to the fire", in other words, make the situation worse and to be honest, Raph wasn't wrong; apart from Leo saving a gang of mobsters from an exploding warehouse and evacuating a man trapped in a bus, the Turtles weren't making much progress to end the war until Karai showed up and offered a truce.
  • The Lancer: Raphael will throw the first punch. His rivalry with Leo is played up in this series, and he's Number Two taking charge when Leo is absent.
  • Middle Child Syndrome: Played with. Raphael isn't the middle turtle, but he feels as if no one understands him.
  • Number Two: He's generally calling the shots when Leo isn't around.
  • Red Is Heroic: He's always a hero but typically in on-going series he plays the lancer to Leo while in one-off stories he is the main protagonist who usually has to overcome his anger.
  • They Really Do Love Each Other: Despite sometimes being a jerk to his brothers, Raphael is very protective of them.
  • This Is Unforgivable!: Raph doesn't take too well to having been paralyzed by one of the hornets in the episode "April's Artifiact".
  • Throwing Your Sword Always Works: Raph throws his sai a lot.
  • Took a Level in Kindness: It's more so "losing a level in jerkass", but by Back to the Sewers, Raph was no longer beating up Mikey or challenging Leo's authority, though he still flung a few insults here and there and even those were reduced.
  • Unskilled, but Strong: Raphael has immense strength and great ability, but his temper often clouds his judgement and often acts out in his rage moments.
  • Unstoppable Rage: You had better hope you never catch Raph on a bad day where he is extremely angry.
  • Weapon of Choice: Sai Guy.
  • What the Hell, Hero?: In "Meet Casey Jones", Leo and Don call Raph out when he loses his temper and almost attacks Mikey with a metal pipe.
    Leonardo: Raphael! Have you lost your mind?!
    Donatello: You OK, Mikey? What were you thinking, Raph?!
  • Why Did It Have to Be Snakes?: A running gag throughout the series is Raphael's fear of bugs (entomophobia). However, in this adaptation, it is less a phobia, and more of an intense hatred and disgust

The wiseguy. Known as "Mikey" to his brothers, his personality is more akin to the Mirage comics than the 1987 TV series. Still the comic relief, he often makes statements that spoof pop culture, although he uses less surfer language than in the 1987 cartoon series. His trademark nunchaku are once again his primary weapons, but he has used other weapons such as grappling hooks and those of his brothers.

  • Adaptational Jerkass: Not the most jerkish of jerks, but this Michelangelo is a lot slower to show the warm, emotional side that characterizes most of his other versions. In the other continuities, Mike is an unquestioned Nice Guy, but he's more a Jerk with a Heart of Gold in this adaptation.
  • Arbitrary Skepticism: Michelangelo is the first to encounter Leatherhead, and when he tells them, the rest of the Turtles disbelieve him. At this point in the series, they have already encountered/know the existence of ninjas, criminal organizations, superheroes, cryptids, aliens, and mystical forces, yet a giant crocodile (mutated in the same way they were) is unbelievable. Leo does admit to remembering the giant alligator he encountered with Raph in the sewers when they were young, however.
  • Attention Whore: Especially after he wins the Battle Nexus tournament as he brags about being a multiverse champion.
  • Arrogant Kung-Fu Guy: Mikey is very arrogant and often underestimates his opponents with his childlike personality. Especially after he won the Battle Nexus Tournament and claims that he doesn't need training.
  • Badass Adorable: Silly, loves him some comic books, childish, always willing to crack a joke and and can kick tons of asses with his nunchucks.
  • Beware the Nice Ones: He's the friendliest and silliest of the Turtles, but he can be downright dangerous when he wants to be.
  • Beware the Silly Ones: Raph thought he was in for a cakewalk when they were matched up in the Battle Nexus. Unfortunately, years of joking on Raph means that Mikey knows exactly how to push his buttons and make him come undone. Mikey wins the fight with almost nothing but his mouth.
  • Big Eater: He'd often annoy his brothers by eating all the pizza and is almost always hungry.
  • Boisterous Bruiser: He loves to throw his weight around.
  • Brilliant, but Lazy:
    • He's usually portrayed as having great potential, but because of his more laidback personality, he'll focus on something more fun instead. Despite training the least, he's usually seen as at least being a better fighter than Don. He managed to beat Raph in the Battle Nexus, (and win the tournament overall via fluke at first, but later legitimately defended his title in a rematch that was rigged against him). Splinter notes that if he trained as seriously as the others, he would probably be consistently the best turtle.
    • This is enforced with his Weapon of Choice (the chucks, see below), the laziest of the turtles is the one wielding the most complex and difficult weapon. That's not something one can do without a gift for it.
    • "Graduation Day: Class of 2105" has him nearly fail to graduate to the next rank of ninjutsu because he's been slacking off too much, but he's able to make it up in one night or so.
  • Butt-Monkey: If any of the Turtles klutzes out or has something bad happen to them for comic effect, it's Michelangelo.
  • Catchphrase: The most famous "Cowabunga!"
  • Character Development: Michelangelo finally grows up, begins to use his innate skills to his full potential, and proves his worth as a thoughtful member of the team.
  • Crouching Moron, Hidden Badass:
    • In Michelangelo's first centric episode, he becomes a superhero, saves another superhero, and during all this learns a lesson on why he's a ninja: because it's what he does best.
    • In "Touch and Go", Splinter tells him that he is the most naturally athletic of his brothers and he is crowned the winner of the Battle Nexus on a technicality (although with Leo's training, he wins outright in "Grudge Match").
  • Fun Personified: The most consistent source of laughs and fun in the series, even during its darker moments.
  • The Heart: Although he exasperates his three brothers on a constant level, when a serious rift between their bond takes place, he usually is the one to try and patch things up...usually via humor.
  • Hidden Depths: In spite of being the laziest of the Turtles, he's the one with two of the weapon that's the most difficult to master. He's also surprisingly introspective and sometimes analyzes the nature of his brothers.
  • The Gadfly: He loves to rile up his brothers, especially Raphael, by annoying them with puns, jokes and chatter at inappropriate moments. Sometimes he's not annoying them on purpose, but other times he definitely is.
  • It's All About Me: He has frequent moments like this, and can be extremely self-centered and selfish at times. Luckily, this doesn't stop him from wanting to do the right thing when the chips are down.
  • Jerk with a Heart of Gold: Perhaps unintentionally from the creator's perspective, but he can be a pretty big jerk in this series, partly due to his frequent Innocently Insensitive and It's All About Me moments, as well as his role as The Gadfly. However, he's never malicious or intentionally cruel and, when it comes down to it, he really is a good guy who wants everyone to get along.
  • Jumped at the Call: He's usually the most nonchalant about all the weird and out-there places the Turtles are taken to - especially when it involves superheroes.
  • Kindhearted Cat Lover: Just like in the comics, Mikey adopts a stray kitten he names "Klunk", who sticks around for the rest of the series.
  • Keet: Extremely energetic and has a childlike persona when he goods off a lot.
  • Large Ham: Especially as the Turtle Titan.
  • Legacy Character: Not himself, but his superhero persona, the "Turtle Titan", inspires Silver Sentry's descendant around the year 2105 and he begins work under the title. Mikey is initially enraged and tries to undermine him until he learns how much his old persona meant to the kid, and relents.
  • Lovable Coward: This version of Michelangelo is a bit of a scaredy-cat compared to other versions, at least early on. He's by far the most easily spooked of the Turtles and the one most likely to scream in fear or suggest giving up in the face of overwhelming adversary. Over the course of the series he gradually becomes more of a Cowardly Lion, and at the end of the cartoon his cowardice has pretty much vanished.
  • Leeroy Jenkins: He doesn't usually think of a strategy before heading into battle.
  • Papa Wolf: To his kitten, Klunk. When Karai attacks the lair in Season 4, he pulls out all the stops to escape with Klunk unharmed, and the kitten is better taken care of then he is.
  • Plucky Comic Relief: He got this role in the show and held onto it throughout all other versions with his funny business. "The wise guy is, Michaelangelo."
  • Pungeon Master: Much to his brothers' continued annoyance. His constant puns almost always trigger negative reactions from his brothers — ranging from groans, Facepalms, and derogatory looks, to outright physical punishment such as head-slaps, flicks, and pulling the ties of his ninja mask. However, his brothers aren't immune to it either: on the rare occasions when one of them says a bad pun they'll almost always get a similar Lame Pun Reaction from another turtle, though it's typically not as aggressive as the reactions dished out on Mikey.
  • Real Men Wear Pink: In Back to the Sewers, he was positively delighted when April asked him to be her Maid of Honor and when people tried to call him the more gender-neutral "Turtle of Honor" he would correct them.
  • Screams Like a Little Girl: Does he ever have the most high pitched scream.
  • Secret Identity: Turtle Titan, a superhero he drafted up in "The Unconvincing Turtle Titan".
  • Skilled, but Naïve: Mikey has very great potential to be a good ninja with his strength and skill but he's just way too lazy and arrogant to improve his abilities.
  • The Slacker: Splinter even calls attention to the fact that he's the most naturally talented, but trains the least.

The brains of the bunch. Donnie is still the smartest turtle, like the other versions, and is more pacifistic compared to his brothers. He gets easily excited over new tech or fascinating creatures, causing him to be distracted even during bad situations. Because of this, he loves the future for its new technology and gadgets. Despite seeing things such as time travel, other dimensions, and aliens, he still maintains a scientific view of the world and disbelieves any wild fantasies not seen in first-person.

  • Adorkable: Especially when squeeing over new technology and goes full on nerd mode.
  • Badass Bookworm: He's an Omnidisciplinary Scientist par excellence as well as a skilled warrior.
  • Badass in Distress: The time he was captured by the Triceratons, and the end of the outbreak arc after being mutated a second time. Less dramatic instances are scattered throughout the series, too, usually when it would be easy for him to solve a problem/end an episode before its time.
  • Badass Pacifist: He would prefer not to use his weapons and fists to solve a problem. Emphasis on prefer.
  • Beware the Nice Ones: He may be the most gentle of the Turtles, but you don't want to earn his genuine wrath.
  • Beware the Quiet Ones: Usually the quietest, most thoughtful member of the team, but also one of their most crucial assets and leaders.
  • Big Little Brother: Taller than Leo but, fittingly, tied with Raph, despite being younger than the two.
  • Bond Breaker: Donatello was warped into an alternate future where he had disappeared for 20 years. Without his resourceful, tech savvyness, the Turtles were disbanded and the Shredder had succeeded in world domination. The supporting cast made up the last rebel resistance.
  • Fighting from the Inside: A variant while he was prisoner on board the Triceraton mother ship, resisting against borderline Mind Rape. He held out for awhile, but needed help to fend the assault off.
  • Future Me Scares Me: One episode of the Fast Forward season has a future journal suggesting that robot butler Serling might be Donatello's future self. Donnie and his brothers are grossed out by the idea. Fortunately, the journal is a fake set to discourage the turtles from trying to learn too much about the future.
  • Gadgeteer Genius: Considering that he's self-taught, living in a sewer, and working mostly with scavenged junk, Don's inventing abilities are downright super-reptilian.
  • Gentleman Snarker: He's second only to Splinter where polite snarking is concerned, but still retaining his smart qualities.
  • Intelligence Equals Isolation: Not often, but on occasion he's sequestered off in his lab. Most noticeable in 'Return to the Underground'.
  • The Klutz: A trait that doesn't come up often — but if/when it does, it's always in the middle of a fight or stealth mission.
  • Lovable Nerd: Ever so much, when he geeks out about his projects.
  • The Reliable One: He's the one that builds most of their supplies and support items that his brothers rely on him for.
  • Resist the Beast: Happens to Donatello in "Adventures in Turtle Sitting". He even begs April and Casey to "stay away from" him as he runs off, before he mutates fully and starts to attack them.
  • Sesquipedalian Loquaciousness: Donatello, being the smart turtle, is particularly fond of this. A notable example is in "The Shredder Strikes Back, Part 1", when he and Raphael are watching a football match on television.
    Raphael: 'Panthers', 'Rams', 'Bears', they even got 'Dolphins'. You'd think they'd have room for something a little more...reptilian.
    Donatello: The 'Turtles'? My friend, unfortunately the lowly turtle has been saddled by society with the stereotype of being velocity challenged.
    Raphael: Say what?
  • The Smart Guy: In terms of science and technology he outclasses his brothers with his intellectual brain and often comes up with their most valuable resources "Donatello, the brains of the bunch."
  • This Is Unforgivable!: In "Same as it Never Was", after stating a Big "NO!" upon watching the Karai Legions kill Future Mike to his horror, Don gets pushed too far. His response? "You'll pay for this, Shredder! If it's the last thing I do, YOU WILL PAY!"
  • Weak, but Skilled: Unlike his brothers Don isn't the strongest of them but he makes up for it with his skill long range weapon or his technological advancements.
  • Weapon of Choice: His famous Simple Staff.
  • Weirdness Magnet: Even amongst his brothers as he nerds out over the littlest of technology.
  • Wrong Genre Savvy: Demonstrated a couple of times — like trying something he saw in a movie during a fight with the Foot. It doesn't work.

Splinter is the adoptive father of Leonardo, Raphael, Donatello, and Michelangelo. He raised them and taught them in the art of Ninjutsu. He is portrayed as a dark gray rat in monk's robes and is stated to weigh 90 lbs.

  • Adaptation Dye-Job: Splinter's fur is turned gray for this series.
  • Adaptational Heroism: The comic Splinter made no bones about the fact that he was training the turtles to avenge Hamato Yoshi's death. This version avoided telling the turtles about the Shredder so that they wouldn't get a desire for vengeance like he did.
  • Adventure Rebuff: Splinter tries this several times, unsuccessfully.
    Splinter: How many times have I told you not to sneak out to the surface?
    Michelangelo: This month?
    Donatello: Five hundred and twelve, actually.
  • Big Good: He and the Ancient One take up the role in the back half of the fifth season.
  • Blood Knight: Entered into a tournament of the Nexus multiverse to prove his strength and fight many skillfull warriors.
  • Bow and Sword, in Accord: Splinter is armed in this manner in the first episode of the "Exodus" two-parter.
  • Cool Old Guy: Sometimes joins the Turtles in their pastimes of fun and their jokes.
  • Deadpan Snarker: Fans tend to agree that he has some of the best lines in the show that shows off some of his sarcasm.
  • I'm a Doctor, Not a Placeholder: In one of the clip show episodes, the Turtles and Casey get into a play fighting scuffle. April jokingly asks Splinter if he'll teach the Turtles manners next. However, he's a teacher of ninjutsu, not a teacher of proper etiquette.
    Splinter: Miss O'Neil, teaching them the ancient art of ninjutsu is hard enough. I am afraid even I can't work miracles.
  • Koan: Splinter is fond of these. Subverted on one occasion when he had to explain what he was saying.
    Splinter: Remember, my sons, even the mighty oak bows before the raging storm winds.
    Mikey: Huh?
    Splinter: Be careful and do not become overconfident!
  • Leitmotif: A tranquil theme played on a flute.
  • Not So Above It All: He loves his soap operas, beats out Casey and Raph in poker several times, snarks periodically about his sons' antics, and even cracks a joke here and there.
  • Old Master: An elderly master of ninjutsu. He's much older than the Turtles, but is still a capable fighter when he needs to be.
  • Offhand Backhand: When the Shredder and the Foot Ninja attack April's antique shop, Master Splinter smacked a Foot Soldier with his stick without even turning back. He does this again to another Foot ninja when Karai invades the Lair and maybe once more at one point in between.
  • Overprotective Dad: Not just towards the turtles but also towards April, Casey, and Cody (who also has Serling). Even risking his own life despite being older.
  • Papa Wolf: He will not take kindly to anyone who harms his four students.
  • Parents in Distress: For all of the times Splinter has rescued his sons, he has to be rescued by them often as well.
  • Pint-Sized Powerhouse: Short and skinny but a force to reckoned with.
  • Rodents of Unusual Size: While he's still the shortest of the main cast, he's much larger than any normal rat.
  • Simple Staff: His short walking stick
  • Team Dad: To the Turtles and eventually to Casey and April, helping the latter two deal with their training and even relationship problems.


How well does it match the trope?
