     In General 
  • Adaptational Backstory Change: This reimagined version of the Turtles and Splinter are actually natives of Star City (Green Arrow's home turf) as opposed to the Big Applesauce of New York City in most adaptations since New York in Earth-27 has been wiped out from the map following the "Manhattaning".
  • Badass Family: Undeniably so, as they regularly fight off hordes of aliens, monsters, and maniacal humans.
  • Badass Normal: Well, in comparison to most other mutants anyway. The Turtles all rely on their martial arts training, incredible teamwork, and iron will against aliens, superpowered beings and other villains who may have more unnatural capabilities that can be used in battle.
  • Bald of Awesome: By virtue of the Turtles being hairless and very skilled ninjas.
  • Four-Temperament Ensemble: Leonardo the melancholic, Donatello the phlegmatic, Raphael the choleric and Michaelangelo the sanguine.
  • Happily Adopted: The Turtles love and respect Splinter as if he were their real father.
  • Healing Factor: All Mutagen mutants have a healing factor.
  • Metamorphosis: From turtles to humanoid turtles, and from a rat to a humanoid rat.
  • Named After Somebody Famous: The Turtles are named after iconic Renaissance artists.
  • Trademark Favorite Food: Though pizza is the favorite food of all four turtles, Michelangelo eats it more obsessively than the other three.
  • Two Girls to a Team: Thanks to the addition of Venus and Artemisia.
  • Super Toughness: The turtles' shell is about as resilient as kevlar.
  • Weapon of Choice: Each of them has their trademark weapons; Leo has his Twin Katanas, Ralph's Dual Sais, Mikey's Nunchucks and Donnie's Bo Staff.

     Leonardo "Leo" Splinterson 
https://static.tvtropes.org/pmwiki/pub/images/tmnt_leo.jpg

Leonardo is the calm, focused, and disciplined leader of his brothers, the Teenage Mutant Ninja Turtles. Nicknamed "Leo".


  • The Ace: He's The Leader and The Paragon. Although, all of this overachieving is nicely offset by the fact that he's a giant dork and still doesn't really get that much respect from his brothers.
  • Adorkable: Seriously, when did you ever expect to see Leonardo who's into Sci-Fi television shows and tries to emulate them? His adorable face shape, smile, voice, and big blue eyes don't hurt either.
  • Authority Equals Asskicking: Consistently the most skilled Turtle, he falls into the leadership role by default.
  • Berserk Button: More often than not, Raphael is this. Especially when the latter disobeys him or mocks him for being a Teacher's Pet.
  • Blue Is Heroic: His signature blue bandana and he's the leader of the turtles.
  • 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 has twin katanas as his Weapon of Choice, as with most versions. He named both of them as Musashi and Kamiizumi.
  • Emotions vs. Stoicism: A lot of what he puts up with has him wondering if he should fight or remain still.
  • Fanboy: Through he loves all animated series, his favorite is Space Heroes, an old cartoon of what looks like a cheap rip-off of another sci-fi series. Leo found the entire collection of VHS tapes in a dumpster. He often refers to his team as "Hero Turtles" and not "Ninja Turtles".
  • Heroes Prefer Swords: As the leader of the group, Leo gets the shiny swords.
  • The Leader: He is the Levelheaded and Charismatic type. He's the most balanced and mature of his brothers, and he knows how to use people's skills.
  • 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. He had Splinter teach him Japanese and esoteric practices of spiritual nature, which his brothers had little interest in.
  • Trademark Favorite Food: His favorite pizza toppings are onions, black olives, green peppers, and mushrooms

     Raphael "Raph" Splinterson 
https://static.tvtropes.org/pmwiki/pub/images/tmnt_raphael.jpg

Often misunderstood, or dismissed as the dark one, Raphael is known to go to the extremes with his anger. He has a hard time handling his temper, pressured from the unfair facts of life. Most known for his twin sai, red bandanna, and the nickname "Raph" from his brothers and friends.


  • 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 called the "Shell Cycle".
  • The Big Guy: As with many of other versions, Raphael is the strongest of the Turtles; whenever there's a need for brute strength, he's the turtle to call.
  • Good Scars, Evil Scars: He have three deep cuts on his left cheek due to a cat slashed him with multiple cats when he tried to pet the cat as a child which would later developed his actual fear of cats.
  • 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.
  • Jerk with a Heart of Gold: He's more abrasive than the others, but is still as heroic as the other Turtles. He loves his brothers, friends, and adopted father unconditionally.
  • Real Men Eat Meat: His favorite toppings are all meats.
  • Red Is Heroic: His signature red bandana, and while a bit rough, he's the co-leader of the turtles.
  • Red Oni, Blue Oni: He is the red to Leonardo's blue, as reflected by the color of their headbands.
  • Trademark Favorite Food: His favorite pizza toppings are pepperoni, Italian sausage, bacon, and beef.
  • Why Did It Have to Be Snakes?: While he won't openly admit it, Raphael is afraid of flying, cats and cockroaches. He can deal with flying by pulling his mask over his eyes and he can bring himself to tolerate Mikey's pet cat, he is constantly glaring at Klunk. Raphael's fear of cockroaches is a different story as Raph will visibly lock up before bolting away.

     Donatello "Donnie" Splinterson 
https://static.tvtropes.org/pmwiki/pub/images/tmnt_donnie.jpg

Donatello is the scientist and engineer of the turtles. Most known for his Bo Staff, purple bandanna, and the nickname "Donnie" or "Don" as called by his brothers and friends. He is responsible for all the turtles vehicles of transportation.


  • 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.
  • 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: Despite being younger than Leo and Raph, Donnie is the tallest out of the Turtles at the height of 5'3" / 1.6 m.
  • 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.
  • Geek Physiques: Donnie is the tallest of the four brothers, standing half a head taller than Raph or Leo, and is skinny compared to the others.
  • Purple Is Powerful: His signature purple bandana, and while not the best fighter, he's certainly the smart one among the turtles.
  • The Reliable One: He's the one that builds most of their supplies and support items that his brothers rely on him for.
  • 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."
  • Teen Genius: He is a teenage, well-trained ninja who is a technological genius, acquainted with alien technology, and well-versed in fields such as biology and chemistry, seen when he invents retromutagen (with his brother's help at least).
  • Trademark Favorite Food: His favorite pizza toppings are chicken, mushroom, green pepper, and tomatoes.

     Michelangelo "Mikey" Splinterson 
https://static.tvtropes.org/pmwiki/pub/images/tmnt_mikey.jpg

Mikey is the comedian of the brothers, always making a joke. He is the fastest fighter of the group with his two nunchaku. Most known for his orange bandanna, the nickname "Mikey" as called by his Brothers and Friends, and the signature phrase of "cowabunga".


  • The Baby of the Bunch: As is typical of most portrayals of Mikey, he's the youngest, most immature and spacey of his brothers, though no less dangerous.
  • Badass Adorable: Silly, loves 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.
  • Big Eater: Thinks of pizza far more than his brothers.
  • Brilliant, but Lazy: He's every bit as good a fighter as his brothers and Splinter even says that he has more natural talent than all of them, but is also the most laid-back and prone to goofing off.
  • Catchphrase: The most famous "Cowabunga!"
  • 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.
  • Keet: Extremely energetic and has a childlike persona when he goods off a lot.
  • Plucky Comic Relief: As always, Mikey is the least serious of the turtles and the funny guy of the group.
  • 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.
  • Taught by Television: He knows how to do a blood transfusion thanks to watching enough medical dramas.
  • Trademark Favorite Food: His favorite pizza toppings are pepperoni, ham, pineapple, and jalapeño.

     Splinter (Hamato Yoshi) 
https://static.tvtropes.org/pmwiki/pub/images/splinter_erath_27.jpg

A rat mutated by exposure to the mutagenic ooze, Splinter raised the Teenage Mutant Ninja Turtles and trained them in the art of ninjutsu. He is also the mortal enemy of Shredder. He is a father figure to the turtles and is easily able to fight them all at once.

  • Action Dad: He is the Turtles' adoptive father and master ninja mentor.
  • Badass Beard: Has a long beard that fits his Old Master look.
  • Feeling Their Age: Splinter was already aged past the lifespan of a normal domesticated rat when he mutated and as such is quite old.

  • Old Master: He's much older than the Turtles, but is still a capable fighter when he needs to be.
  • Papa Wolf: For all of his snark with his disciples, he genuinely loves them. Threatening them is a good way to get Splinter to show how much ass he can still kick.
  • Prehensile Tail: Splinter has trained his tail to be somewhat prehensile. He often uses this to trip or ensnare opponents, or disarm them.
  • Related in the Adaptation: Yoshi was adopted by Ra's al-Ghul alongside Saki, making him foster brother of Talia, Nyssa and Dusan al-Ghul. That would make him adoptive uncle of Damian Wayne, Connor Hawke and Malcolm Merlyn.
  • Was Once a Man: Originally a human named Hamato Yoshi, he was killed by Shredder, reincarnated as a rat who was mutated into a more humanoid appearance.
  • We Used to Be Friends: Hamato and Oroku Saki were adopted brothers and best friends, but different paths in life have now turned them into bitter enemies.

     Venus de Milo 
https://static.tvtropes.org/pmwiki/pub/images/venus_de_milo_earth_27.jpg
  • Adaptation Dye-Job: Her bandana was originally cyan, but here it's white.
  • Basement-Dweller: April has decided to let her stay in her basement, hoping her sister Robyn doesn't have to change a fuse or something.
  • Dual Tonfas: Fights with a pair of silver-white tonfas.
  • Light Is Good: Wears a white bandana and she's a friendly, if amnesiac, turtle. Or maybe not...
  • Manchurian Agent: She was unknowingly sent by Shredder to capture Splinter and obtain his blood, not being aware of the personality implanted in her mind by Chikara.
  • Odd Name Out: Venus was named after the famous armless statue of the Greek/Roman Goddess of Love due to her habit of drawing her arms into her shell as a means of self-soothing when she's nervous, frightened, or just uncomfortable. Yes, April is aware that the name doesn't fit the theme of the other turtles.
  • Psychic Link: By some unknown means, Venus is able to tap into the quasi-psychic or spiritual connection of the Teenage Mutant Ninja Turtles.
  • Split Personality: Leatherhead reveals that Kitsune used her magic to take control of her mind, creating two personalities, the sweet and innocent "fake" personality and the "real" ruthless personality that serves the Foot Clan.

     Artemisia (Jennika Smith) 
https://static.tvtropes.org/pmwiki/pub/images/artemisia_earth_27.jpg
  • Badass Teacher: Though she is an exceptional trainer in martial arts, she can teach any subject which she has sufficient familiarity with.
  • Broken Pedestal: Grows increasingly disillusioned with Karai and the Foot Clan for turning her brother into a mutant, to the point she refuses her orders and helps the turtles. This makes Karai run her through with a sword.

  • Friend to All Children: Jenny has a soft spot for children and is a skilled instructor, particularly who working with children.

  • Hidden Depths: At first it might look she has an icy demeanor but her true nature features a more complex personality when she lets her guard down. She enjoys good food, spirited debates, and has a soft spot for children of all ages. As to her thoughts on pizza? She likes her Hawaiian style.
  • Named by the Adaptation: In the comics her last name was unknown, but here it's the common surname of Smith.
  • Parental Abandonment: Her father Jeffrey Smith abandoned her, her mother and half-brother Robert before she was even born, while her mother suffered from MacGregor's Syndrome forcing the siblings to take her of her and later died during the Cataclysm of the Glades. She thought her mother's death was a Mercy Kill.
  • Pet the Dog: Tells a (quite incompetent) ninja trainee named Jason to just quit since he has no aptitude for being a ninja rather than punishing him for his carelessness.
    • While hiding her identity she also tries to make her half-brother Rob Smith, who had joined the Sons of Batman, to leave Gotham before conflict between the Foot and other Gotham criminals explodes.
  • Related in the Adaptation: She's the half-sister of Rob Smith/Rocksteady, Christopher Smith/Peacemaker, Giselle Smith/Gazelle of the Advena Legion and Samuel Smith, an enemy of the WildC.A.T.S..

Her ancestor Simon "Slow Go" Smith was a bounty hunter that befriended Jonah Hex.

https://static.tvtropes.org/pmwiki/pub/images/keno_andrada_earth_27.jpg
Keno is a pizza delivery boy and martial artist, as well as an ally of the Ninja Turtles and April O'Neil.
  • The Casanova: Keno is a big flirt. He has an incredible knack for remembering pick-up lines and has little shame in employing them regardless of the situation. The kid's got confidence.

  • Code Name: His Ops Moniker is Courier.
  • Disappeared Dad: His father Ernesto Andrada passed away of kidney disease when he was 14.

Other Allies

https://static.tvtropes.org/pmwiki/pub/images/leatherhead__earth_27__commission_by_phil_cho_ddm5gu7_fullview.jpg
  • Aloof Ally: While at first he opposed the turtles, he now serves as a reluctant ally in exchange for food and medicine, living near the turtles' lair as an extra security measure.
  • The Berserker: He's got a nasty temper, and when provoked or threatened, he will slip into an animalistic rage that is very difficult to stop.
  • Foil: Can be seen as one for Killer Croc. While Leatherhead is a mutated humanoid alligator, Waylon Jones is a human whose mutation eventually turned him more and more crocodilian. And while Leatherhead is a Genius Bruiser, Killer Croc is rather Book Dumb and usually serves as The Brute. Leatherhead is actually considering becoming a vegetarian while Killer Croc is known to have eaten people in the past.

  • Sewer Gator: He's very familiar with Star City's sewer system and can maintain his needs without much problem.

  • Vegetarian Carnivore: He is an omnivore. In fact, so little of his diet includes meat he has considered becoming a vegetarian or even a vegan if he could find a more sustainable source of food. Though he may one day enjoy a tofu lifestyle, he's content to eat what he can find. On rare occasion, he'll even take Mikey up on his offer and join the bros for pizza.
