Teenage Mutant Ninja Turtles/Characters
Characters from the long-running comic book series Teenage Mutant Ninja Turtles, as well as some exclusive to some of its non-comic incarnations.

![]() | This page needs some cleaning up to be presentable. This page describes characters from many different versions of the story. Several characters' allegiances shift between incarnations. This page needs to be split into separate pages, one for each version of the story. (Also, shouldn't there be an entry for Miyamoto Usagi somewhere on two of those new pages?) |

Heroes
Leonardo
Leads. Always in control. Identifiable by his blue bandana and his twin swords.
Appears in: all continuities.
- Authority Equals Asskicking: Consistently the most skilled Turtle, he falls into the leadership role by default.
- The Cape (trope)
- The Chains of Commanding: 4Kids Series, 4th film.
- Child Soldiers: Of the four, it's Leonardo who exemplifies this the most.
- Combat Pragmatist: Leonardo's sense of honor dictates that he fight fairly, but when he's pushed into a corner or there is no other alternative, he will not hesitate to slice off your head.
- Determinator
- Dual-Wielding
- Emotions vs. Stoicism
- Four-Temperament Ensemble: Phlegmatic.
- Guilt Complex: He is very bad with this. Very bad.
- The Hero
- Heroic BSOD: Mirage Comics, 4Kids Series.
- Heroic Spirit: A big reason why he's a determinator.
- Heterosexual Life Partners: With Miyamoto Usagi.
- Honor Before Reason
- Indy Ploy: Alarmingly, a lot of his plans qualify as this. Most of the time, however, they actually work.
- Jack of All Stats: Videogames.
- Katanas Are Just Better: Obviously.
- Martial Pacifist: Mirage Leonardo, in the future.
- Master Swordsman
- 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.
- The Messiah: Even after all the betrayals and all the terrible things he's seen, Leo still expects the best out of people.
- Metamorphosis
- Named After Somebody Famous
- Nerves of Steel: Captured by aliens, trapped thousands of miles from Earth with no way back, poisoned and weaponless? For Leonardo, that's a training run.
- Old Master: Mirage Leonardo, in the future.
- A Protagonist Shall Lead Them: Leonardo usually gets the most lines of dialogue, and most of the stories are told from his perspective. Even when he's not presented as the main character (such as the TMNT movie), he plays a major role.
- Red Oni, Blue Oni: The blue to Raphael's red.
- 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.
- Sliding Scale of Idealism Versus Cynicism: In the 4Kids series, he starts out at the very end of the Idealism scale, even believing the best of the Shredder and then this 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: All the turtles train hard, but Leonardo--whether or not by his own design--is almost always subjected to the kind that involves complete isolation, distant countries, and/or imminent death.
- In the 4Kids series, Leonardo as a child is suffering from 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.
- Standardized Leader: Usually in his most basic, stripped-down incarnations.
- Thou Shalt Not Kill: Mirage Leonardo, in the future.
- Took a Level in Badass: In all incarnations, the turtles all go through this, but Leonardo is the one who most clearly demonstrates the trope. One example is in the first season of the 4Kids cartoon where 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 4Kids cartoon's fourth season, combined with Heroic BSOD.
- Weapon of Choice: Twin Katanas Are Just Better.
- "Well Done, Son" Guy: Most of what Leonardo does is to please Splinter. Whether or not this is a good thing is still a debate in fandom.
- What the Hell, Hero?: Leo gets this in the 4Kids cartoon from his brothers and Splinter when he's on the verge of becoming a Knight Templar.
- Wise Beyond Their Years: In childhood flashbacks, he's usually the turtle acting like the adult. And for a teenager, he deals very well with duties and responsibilities most adults would be unable to fathom.
Raphael
Is cool but crude. Throws the first punch. He wears red and fights with a pair of sais.
Appears in: all continuities.
- Aloof Big Brother: Partially inverted. He's younger than Leonardo making him an aloof little brother, but older than Michelangelo and Donatello, playing straight for them.
- The Berserker: Mostly (every continuity but Fred Wolf cartoon).
- The Big Guy
- Brooklyn Rage
- Deadpan Snarker: Fred Wolf cartoon.
- He has his moments in the movies as well:
Raph: (Examines one of Casey's bats) A Jose Canseco bat?? Tell me... you didn't pay money for this...
- Expy: Of Wolverine in the Mirage comics.
- Eyepatch of Power: All of his future incarnations.
- Fire-Forged Friend: With Casey, in most incarnations.
- Four-Temperament Ensemble: Choleric.
- Glass Cannon: Fastest move rate and attack speed in most games he is featured in, but he has to kiss enemies to hit them with his sai, and has the lowest health. The lack of strength is completely inverted in the comics.
- Good Is Not Nice
- Hair-Trigger Temper
- Jerk with a Heart of Gold
- Jerkass Facade: Oh, he cares. He just doesn't want anyone else to know he cares.
- The Lancer
- Medium Awareness / No Fourth Wall: Fred Wolf series.
- Metamorphosis
- Named After Somebody Famous
- Red Oni, Blue Oni: The red to Leonardo's blue.
- Secret Identity: Nightwatcher, in the fourth movie.
- Took a Level in Jerkass: If you're more familiar with the Fred Wolf cartoon.
- Weapon of Choice: Sai Guy.
- Wolverine Publicity
Donatello
Does machines. Is the brains of the bunch. Marked with a purple headband, and fights with a bo staff.
Appears in: all continuities.
- Adorkable
- Badass Bookworm
- Beware the Nice Ones/Quiet Ones
- 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.
- Also an example of It's a Wonderful Plot, where a character often sees that their team or the whole world is worse off for their absence.
- Big Little Brother: Taller than Leo but, fittingly, tied with Raph.
- Brainwashed and Crazy: Not quite brainwashed, but mutated and certainly crazy enough to live up to the spirit of the trope during the Good Genes arc-- unwitting Face Heel Turn included.
- Crazy Prepared: "What I really want to know is why Don carries around a pigeon puppet..."
- Doesn't Like Guns: Mirage comics.
- 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.
- First-Person Smartass: Whenever he's the one voicing the opening narration in the 2003 series.
- Foolish Sibling, Responsible Sibling: The responsible to Michelangelo's foolish.
- Four-Temperament Ensemble: Melancholic.
- 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.
- 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.
- Layman's Terms: Often the one doing the translating, sometimes visibly annoyed.
- Martial Pacifist: According to his official profile, he'd like to be one.
- Metamorphosis: Twice-- once in the backstory, once at the end of the 2003 toon's fourth season.
- Mighty Glacier: In most games. Slow as a... Well, turtle, but has the most health and the longest reach.
- Mr. Fixit
- Named After Somebody Famous
- Nice Guy
- Number Two: In the original comic series.
- Omnidisciplinary Scientist
- OOC Is Serious Business: Played backwards, actually. We get the 'serious business' part within the first few minutes of Same as it Never Was. Just before the episode's Bittersweet Ending, the OoC part comes in.
- Out-of-Character Moment: Don absolutely slaughters Ch'rell at the end of SaiNW, a far cry from his usually pacifistic actions. Understandable, of course given the circumstances.
- The Professor
- The Smart Guy
- Technical Pacifist: In some incarnations.
- Teen Genius
- Weapon of Choice: Simple Staff.
- Weirdness Magnet: Even amongst his brothers. He's been to at least three different worlds/dimensions that the others haven't, at any rate.
Michelangelo
Is a party dude. Wiseguy. The most laid-back of the turtles, who lists among his interests pizza, comic books, and more pizza. Wears an orange-yellow bandana, and duels with nunchaku.
Appears in: all continuities.
- Annoying Younger Sibling
- Ascended Fanboy: Sorta, he's a big comic book geek who happens to be a superhero himself.
- In the Mirage comics he's a comic book geek who gets to write for comic books and even becomes a published novelist.
- 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. Yup.
- Taken to it's furthest extreme in 2007's TMNT where Mikey is the shortest turtle and has huge adorable Blue Eyes (we know it doesn't make sense, but it's cute, dammit)
- Beware the Nice Ones
- Big Eater: In the 'Fred Wolf cartoon, he'd often annoy his brothers by eating all the pizza.
- 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.
- Butt Monkey: Especially in the cartoons. If any of the Turtles klutzes out or has something bad happen to them for comic effect, it's Michelangelo.
- Characterization Marches On: Depending on the version, really - in the comic books, he isn't really a party dude, but more of a down-to-Earth type of guy as opposed to his brothers. He was able to author a book at one point.
- In the Mirage comics he often traded back and forth with Donatello as The Smart Guy with Donny being the expert in science and technology while Mikey's specialty was culture and literature.
- Cloudcuckoolander
- Crouching Moron, Hidden Badass: (4Kids series): Although he can always kick ass, his skills will occasionally take a bump as the plot requires, allowing him to take on foes that would normally defeat him or his brothers.
- Dope Slap: Gets it a lot in the 4Kids series.
- Foolish Sibling, Responsible Sibling: The foolish to Donatello's responsible.
- Four-Temperament Ensemble: Sanguine.
- Genre Savvy: 4Kids series.
- Hard Work Hardly Works: Although the trope is disproved by Leonardo, there is an element of this to Mikey's abilities, and he is consistently considered to be the most naturally gifted of the turtles despite his lack of focus and dedication to training.
- 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
- Hooks and Crooks: Occurs in later seasons of the original cartoon, due to censorship in England.
- He also uses one briefly in the 4Kids cartoon as a callback.
- Jumped At the Call: 4Kids series.
- Keet
- Kid Appeal Character
- Kindhearted Cat Lover
- The Knight Who Says Squee: 4Kids cartoon.
- Lightning Bruiser: Michelangelo runs faster than Leo and Don and has more health than all of his brothers. However, his nunchucks are slow and have little range (Turtles in Time, The Arcade game, Manhattan Project).
- Metamorphosis
- Real Men Wear Pink: in Back to the Sewers he was positively delighted when April asked him to be her Maid of Honor, when people tried to call him the more gender-neutral "Turtle of Honor" he would correct them.
- The Red Mage: In the games, average movement speed and faster attack speed than Don, but defensively weaker than Leo.
- Screams Like a Little Girl: 4Kids series.
- Secret Identity: Turtle Titan (4Kids cartoon).
- The Slacker: 4Kids series.
- Surfer Dude: Mostly in the 'Fred Wolf cartoon, although aspects of this remain in other incarnations.
- Took a Level in Jerkass: In the Next Mutation series. To a lesser extent, in the 4Kids series as well.
- Trademark Favorite Food: Though pizza is the favorite food of all four turtles, Michelangelo eats it more obsessively than the other three, especially in the 'Fred Wolf cartoon.

- Action Girl

- The Chick
- Funny Foreigner: She never did manage to learn that the Turtles lived in the "sewer" and not in the "toilet."

- But fan drawings love to emphasize them. Really, Venus isn't a Base Breaker, her breasts are!

- Retcon: During her introduction, Venus was somewhat clumsily inserted into the Turtles' already-established origin.

Renet
An apprentice "Timestress" whose job it is to oversee and protect the timestream.
Appears in: Mirage comics, 4Kids cartoon
- Character Development: (Mirage) Initially a ditzy, irresponsible and overly impulsive girl, she eventually evolves into a mature, responsible and self-reliant woman -- after having spent some time as grim-faced, solemn and reluctant. What makes it confusing is that, thanks to her traveling back and forth through time, we don't necessarily see this development in chronological order.
- In fact, we're informed that her parents originally made her take the job as an apprentice timestress in the hope that she would undergo some much-needed Character Development.
- Deus Ex Machina: In the Mirage comic Juliet's Revenge the fully-adult, post-Character Development Renet plays this role (having changed so much that the Turtles don't recognize her at first). For the most part, however, she averts this.
- The Ditz: In her pre-Character Development appearances.
- Dumb Blonde: Again, pre-Character Development she's the embodiment of this trope.
- Forgotten Phlebotinum: She's completely and inexplicably absent from the Fast Forward season of the 4Kids cartoon, where the Turtles are stuck in the future -- because if she'd appeared she could instantly have fixed their predicament.
- Ms. Fanservice: (Mirage) About the only thing that stays consistent about her appearance is her huge breasts and tendency to wear skintight (and sometimes rather revealing) clothes.
- Most Common Superpower: It's especially prominent in the Mirage comic (especially if Jim Lawson is drawing her), but the 4Kids cartoon version is notably endowed as well.
- Shout-Out: The third movie prominently features a time travel scepter that looks very similar to Renet's.
- Time Police
- Took a Level in Badass: (Mirage) It's a long way from the Damsel in Distress we're first introduced to, to the nearly god-like woman who shows up to save the Turtles from certain death.

Appears in: Mirage comics, 'Fred Wolf cartoon, Archie comics, 4Kids cartoon, Dreamwave comics, IDW Comics.

- What Happened to the Cat?: When Shredder attacks April's apartment in issue 10, Klunk is nowhere to be seen, and isn't even mentioned when April, Casey and the Turtles escape. (This is doubly frustrating because he was explicitly shown to be in the apartment in the Leonardo special, which takes place immediately before.) He remains unmentioned for several issues before he shows up on Casey's farm with no explanation at all.
