Inhabitants of New York
April O'Neil
April O'Neil
Voiced by: Veronica Taylor Foreign VAs
April O'Neil is an ally and big sister/motherly-figure to the Teenage Mutant Ninja Turtles.
- Adaptational Badass: The Aprils of the original comics, the Fred Wolf cartoon and the 90s live-action movies were generally damsels in distress and had little use in combat. Over the course of the series, this April becomes a good fighter in her own right after some training from Splinter.
- Adaptation Dye-Job: April's hair is now unnaturally red and given a purplish tone.
- All Girls Want Bad Boys: April is shown to have an attraction to Casey Jones, though their contrasting personalities often make them bicker.
- Badass Bookworm: A highly intelligent scientist and a certified Badass.
- Bare Midriffs Are Feminine: She's the Turtles' primary female ally who is primarily shown wearing a purple crop top.
- Battle Couple: With Casey, eventually.
- Big Sister Instinct: She loves and cares for the turtles that she's willing to risk her life to defend them.
- Cool Big Sis: She acts as this to the turtles.
- Leitmotif: A quiet, low-key theme that generally plays when she’s in her antique shop.
- Girly Girl with a Tomboy Streak: She is mostly very feminine and scientific and wears both a mifdriff revealing outfit and a clean and held back bun. Later becomes both a good fighter in her own right and efficient in jujitsu. She even becomes a full-blown Jungle Princess at one time and is able to take out the local giant hornets.
- Letting Her Hair Down: Inversion: If April's hair isn't in her trademark bun the situation generally isn't good.
- Mission Control: This version of April makes much more use of her scientific expertise and she often uses her computer skills to aid the Turtles. The most prominent example of this is in the "Return to New York" three-parter, where the Turtles and Splinter assault Shredder's tower, all the while April communicates with them and gives the layout of the building.
- Mythology Gag: In the episode "Secret Origins", April poses as a TV reporter to infiltrate a building, wearing a very familiar yellow jumpsuit; when she tries to "interview" the soldier supervising the blockade around the Utrom building (it's complicated), she explains that she's from "Channel 9 News *broken tag on jumpsuit flips down* er, Channel 6 News". Later, once the smoke clears, Leonardo says April would make a good reporter, to which she replied "In another lifetime, maybe."
- Nice Girl: She can be very headstrong and sassy, but she's mostly very sweet, kindhearted, caring and levelheaded to everyone she loves.
- Ninja: In-training from Season 3 and onward when she starts getting lessons from Splinter.
- Not So Above It All: Most notably in "April's Artifact" where she gets waaay into the Jungle Princess role and "The Christmas Aliens" where she sticks a spoon on her nose and grins stupidly.
- Prim and Proper Bun: She normally wears her hair like that, as she's very levelheaded and sometimes strict, though she also as a few silly moments (in "April's Artifact" where she gets waaay into the Jungle Princess role and "The Christmas Aliens" where she sticks a spoon on her nose and grins stupidly).
- Took a Level in Badass: In season 2's "April's Artifact", April and the Turtles are transported to an alien jungle planet. There, she becomes a full-blown Jungle Princess and is able to take out the local giant hornets. At the start of season 3, she also begins to train with Splinter.
- Unfazed Everyman: After her initial scream and/or faint upon meeting the turtles, she becomes this.
Casey Jones
Casey Jones
Voiced by: Marc Thompson Foreign VAs
Casey Jones is a hockey-masked vigilante who fights crime at night.
- Adaptational Angst Upgrade: He was given a tragic backstory (See Dark and Troubled Past below) that his original Mirage comics counterpart lacked (it's especially jarring considering Eastman and Laird originally conceived him as someone who became a vigilante because he watched way too many "bad cop" shows instead of the usual "someone killed his family" origin). This backstory, however, was adapted in the comics later onwards.
- Badass Normal: The only member of the team who doesn’t have any mutant powers or abnormal origins. Ninjitsu also doesn't rub off on him the way it does on April.
- Bash Brothers: With Raph.
- Battle Couple: With April.
- Batter Up!: Often wields a bat as well as his signature hockey stick.
- Berserk Button: He really hates the Purple Dragons. Especially their leader Hun.
- The Berserker: Initially since he's the one to throw himself into a fight before anyone.
- Big Brother Instinct: He will step headfirst into battle whenever the turtles are in trouble.
- Big Damn Heroes: Gets to do this occasionally. One stand out moment is him saving the Turtles, Splinter and April when they were outnumbered and surrounded by the Foot Clan. By barging into April's store with his motorbike
- Boisterous Bruiser: Often on the frontline and loves it.
- Brooklyn Rage: Has a Brooklyn accent and is easy to anger.
- Butt-Monkey: Is often on the receiving end of a lot of jokes.
- Car Fu: The Motorcycle variant, when coming to the rescue of the Turtles, he makes good use of his bike when fending off the Elite Foot.
- Character Catchphrase: It's revealed that the young turtles were teaching him all about martial arts and fighting (although they never found out) and each took turns to teach him what they knew. The cry comes from when Mikey was training him and told him to say "Gorogoro-sama!" (translation: Lord Thunder). But since Casey couldn't pronounce it correctly, he made his famous phrase "Goongala!".
- Combat Pragmatist: Even the bad guys admit that Casey just plain fights dirty.
- Cool Big Bro: He acts as this to the turtles.
- Cool Bike: Owns a pretty sweet Harley-Davidson style motorcycle that he understandably is rather proud of.
- Dark and Troubled Past: Casey's hatred of crime is rooted in this incarnation in his childhood. While Casey was still a kid, his father Arnold Casey Jones, Sr. refused to pay protection money to the Purple Dragons. His father's shop was burned down as a result, and a teenage Hun threatened Casey to tell his father to pay up next time. Despite being threatened not to, Casey's dad subsequently went to the police, but with no success; it's implied that the Purple Dragons later killed him for trying to turn them in.
- Early Installment Character-Design Difference: His child self in his debut episode looks like a smaller version of his adult self
◊ complete with long hair. In The Lesson, he has a different hairstyle◊ and that same design is reused◊ for the flashback sequence in Dragons Rising, which seems to be set at least a day or two earlier than the flashback from Meet Casey Jones. - Embarrassing First Name: Arnold. Casey is his middle name in this continuity.
- Fire-Forged Friends: His friendship with Raphael consistently begins this way, eventually leading to him befriending the other turtles and essentially being an honorary brother to them.
- Forgotten First Meeting: It is revealed in “The Lesson” that Casey actually first met the Turtles when they were young and they tried to help him but since the Turtles were disguised and he went by Arnold then neither are aware of it.
- Good Is Not Nice: In his debut episode. He gets better though.
- Heroic Build: He is built like a bodybuilder and is introduced while doing bicep curls with a dumbbell like in the comics.
- Hot-Blooded: Casey is mostly a very boisterous and energetic person with a large amount of gusto, but there are times where he can get so angry that even Raphael has been disturbed by it on occasion with his intense aggression against those he aims it towards.
- Hunk: He is a tall, muscular and handsome man who almost always wears sleeveless clothes.
- I Know Madden Kombat: Casey uses sports equipment as his main weapon.
- Improbable Weapon User: Hockey sticks, baseball bats, golf clubs, croquet mallets, cricket bats...
- The last being really amazing because you gotta know what a crumpet is to understand cricket!
- Innocently Insensitive: Pairs with the No Social Skills below. He just says the first thing that comes to mind and is confused when people, mostly April, are upset.
- Leitmotif: An aggressive guitar riff matching his demeanor.
- Mask Power: When going into action, Casey usually wears an unique old-school hockey mask.
- Middle Name Basis: First name is Arnold but goes by his middle name Casey. His mother still calls him Arnold though.
- Mr. Fanservice: His default outfit is a sleeveless muscle shirt that shows off his physique, and his abs are occasionally visible through his outfit. He is also Tall, Dark, and Handsome.
- No Social Skills: Due to his only focus being to get stronger and take down bad guys most of his life, he's not very well-versed in manners or even basic etiquette. A few of the first interactions with the turtles, and especially April, have him getting on everyone's nerves for never taking a hint or watching what he says.
- Overshadowed by Awesome: He straddles the line between Badass Normal and this depending on the situation. Being an important friend and ally to the Turtles, Casey kicks all sorts of ass when he and his buddies are leaping from roof to roof, beating up Purple Dragons, Foot Soldiers, and your average Mooks. But when it comes down to battling against more powerful enemies such as Karai, Agent Bishop, the Triceratons, General Khan, and the Shredder, it's made painfully clear that Casey isn't really in the same league as the Turtles and the bigger, nastier villains. Usually, he is taken out quite early on while the Turtles are able to battle the Giant Mooks, Dragons, and Big Bads on more even terms.
- Took a Level in Badass:
- Casey undergoes a bit of this in Back to the Sewer when training under Master Khan (he manages to sneak attack and take down all four of the Turtles in this episode) but brainwashing is involved and the show doesn't give any strong indication of whether he retained his newfound fighting skills afterwards.
- However, Casey still applies to this trope as it was revealed that when he was young, Casey lacked the confidence he shows as an adult, until the Turtles trained him to be assertive.
- Vigilante Man: As he grew older, Casey became a vigilante and started hunting down crooks — particularly Purple Dragons — in the streets, until he met Raph.
Angel
Angel
Voiced by: Tara Jayne
Angel: If I want to be a purple dragon, it's my own business.
A young girl from Casey's neighborhood, who wants to become a Purple Dragon.
- Back for the Finale: After not appearing since "Prodigal Son" from season 4, she returns for the finale of "Back to the Sewers", where she attends April and Casey's wedding.
- Canon Immigrant: Was originally created for this series, but a version of her was adapted in the IDW comics.
- Girlish Pigtails: Though she's tomboy.
- Fantastically Indifferent: Her reaction to seeing four mutant turtles? Calling them off the charts.
- Heel–Face Turn: Initially she wanted to become a Purple Dragon, but after seeing how bad they beat up and capture Casey, she goes to the Turtles and asks them for help in order to rescue him.
- Heel Realization: Seeing Casey getting hurt and locked up by Hun show Angel the error of her ways
- It's All My Fault: She blames herself for Casey getting captured by the Purple Dragons.
- Police Are Useless: In "The Darkness Within", Angel tried getting help from the police but they refused to look for her brother. Justified, since they needed to use the resources to rebuild after the Triceraton invasion.
- Parental Substitute: She and her brother live with their grandmother.
- Tomboy: She initially wanted to join the Purple Dragons and could take two thugs in a fight (for awhile at least).
The Professor
The Professor
Voiced by: Greg Carey and Dan Green
The Professor: I have a theory about that.
An intelligent homeless man, who's a friend of the Turtles.
- Another Story for Another Time: Or in his case, his "theories".
- The Bus Came Back: After "Garbageman", he reappears in "World Collide" part 1 and later attends April and Casey's wedding, playing the piano.
- Cloud Cuckoo Lander: Played with. The other homeless people see his "theories" as this, though in reality his theories are some, who are actually shared with the scientific community and a few of them are actually believed to be true.
- Defiant to the End: In "Garbageman", he refuses to kneel before the titular villain.
- Everyone Calls Him "Barkeep": He's only known as "The Professor" and we never discover his true name.
- I Choose to Stay: During "The Garbageman", him and his homeless friends are captured by the titular villain and are brought to his island, where they are forced to work as slaves. Despite this, after the Garbageman and his thugs' defeat, the Professor and the other vagrants decide to remain on the island, as it has both good food and shelter.
- King of the Homeless: After Garbageman's defeat, he becomes a good and wise leader to the homeless and gives a valuable aesop on recycling.
- The Professor: He's obviously one. Becomes a bit confusing in "Worlds Collide" part 1, where he interacts with Donatello and Fugitoid.Donatello: Professor!
Professor Honeycutt: Yes?
Donatello: No, the other professor.
Kirby King
Kirby King
Voiced by: Mike Pollock
Kirby: Life at best is bittersweet.
A gifted artist who's a tenant of April's. He found a mysterious crystal and, after attaching it to his pencil, anything he drew could come to life.
- Adaptational Origin Connection: The "magic crystal" Kirby found is the same kind the Turtles encountered in the underground city from the "Notes from the Underground" three-parter.
- Art Initiates Life: After attaching the magical crystal to his pencil, anything he drew came to life. Though after a while his drawings will disappear. Some of them are the warriors and the Black Horde.
- Ambiguously Brown: This applies to both Kirby and some of his human drawings.
- Another Dimension: It's eventually revealed that his drawings after disappearing are teleported to an alternate world, where his warriors and the Black Horde are at war.
- Heroic Sacrifice: When the portal connecting the other dimension to the real world starts shrinking, he orders Don to go first and even helps him pass through the rapidly shrinking portal. The portal closes leaving him trapped in the other dimension and all he manages to do is send a note to Don.
- No Celebrities Were Harmed: He's an obvious homage to Jack Kirby.
- One-Shot Character: He only appears in one episode.
- Power Crystal: He found one in a coal pile. When its attached to his pencil, whatever he draws comes to live.
- Purple Is Powerful: His magical crystal is purple and can bring his drawings to life.
- Seen It All: He is initially taken aback by Don's sudden appearance, believing him to be the owner of the warp crystal. But after Don clarifies he means no harm, he is not very surprised that a big Turtle is talking to him.Don: Say, doesn't my appearance freak you out a little?
Kirby: Fella, since my sketches started leaping off the page, I've seen freakier, believe me. - Teleportation: The only drawing that hasn't disappeared is a teleporter. It actually leads to the alternate world where the other drawings are transported. At the end of the episode, it begins to disappear. Donatello escapes in time, but Kirby doesn't.
Mutants
Quarry
Quarry
Click to see his human form
her human formVoiced by: Eric Stuart (Quarry) and Megan Hollingshead (Sydney)
Quarry: Those crystals are the embodiment of evil.
Quarry is one of the many individuals that were kidnapped and mutated by the Foot.
- Acid Attack: Her main form of attack.
- Censor Steam: When Quarry is unfrozen and reverted back to her human form in "Notes from the Underground, Part 3", there's some convenient steam that covers her naughty bits.
- Foreshadowing: If you look closely at Quarry's design, you may see that they have long hair. This foreshadows the reveal that he, or she, is in fact a girl.
- In "Notes from the Underground, Part 2", Quarry only remembers that their name started with an S. In "Return to the Underground", his name is revealed to be Sydney.
- Given Name Reveal: In "Return to the Underground", Quarry is permanently cured and tells the Turtles her name: it's Sydney.
- Horrifying the Horror: Just saying "horrified" will be an understatement. In "Notes from the Underground, Part 3", Quarry is absolutely terrified of Necropolis and the entity that lurks within it.
- "I Know You're in There Somewhere" Fight: In "Return to the Underground", the Turtles find that she has gone feral. Mikey tries this on her, but it doesn't work.
- It Can Think: While the other mutants are also quite intelligentnote , special mention goes to Quarry, since she understands how to use the underground crystals and how to use the Foot's technology.
- Naked on Revival: When Quarry seems to be cured at the end of "Notes from the Underground, Part 3", he, or in fact she, doesn't have any clothes.
- Samus Is a Girl: At the end of "Notes from the Underground, Part 3", Quarry is the first "cured" mutant and the Turtles discover that she is a girl, since her mutated form had an androgynous appearance.
- Suddenly Speaking: During the entirety of "Notes from the Underground, Part 1" and the first half of Part 2, she remains silent, up until she realizes that the Turtles are not their enemies.
- Tears of Joy: Quarry after returning to the surface as a human.
- Wall Crawl: As a mutant, Quarry is able to craw the walls of the caverns, though that isn't exclusive to her.
Stonebiter and Razorfist
Stonebiter and Razorfist
Stonebiter
Razorfist
Stonebiter and Razorfist are the companions of Quarry. Strong and intelligent, they are two of the three Underground Mutants who haven't gone feral.
- Ambiguous Situation: Are they not capable of speech due to their mutation, or are they capable but refuse to?
- Dishing Out Dirt: Sort of. Stonebiter has the ability to dig, but he doesn't have any powers over the earth.
- Genius Bruiser: Downplayed, as while they can pretty much use brute force when fighting the Turtles, the two have been shown to use tacticts against them: Stonebiter caused an earthquake that nearly engulfed the Turtles, while Razorfist pushed a giant boulder against them.
- Meaningful Name: Razorfist has giant pincers, while Stonebiter can dig through the earth.
- Mythology Gag: Stonebiter's appearance is very similar to Complete Carnage, a minor villain from the Mirage comics.
- Power Pincers: Razorfist has these.
- Red Eyes, Take Warning: Stonebiter has red eyes, but he isn't evil.
- Scary Scorpions: Razorfist resembles a giant mutated scorpion.
- Suddenly Speaking: While completely silent in the show, Razorfist says one line in a cutscene of the video game. He doesn't say anything else before or after.
- Temporarily a Villain: In "Return to the Underground", they go feral alongside all the other mutants until they are cured.
- The Worf Effect: They get hit pretty hard with this. In "Notes from the Underground, Part 1" and the first half of Part 2, they go head-to-head with the Turtles. Then in the second half of Part 2 and all of Part 3, they are scared from the other mutants and are easily overpowered by them. It serves to establish that the other mutants are much more powerful and fierce than they are.
Leatherhead
Leatherhead
Voiced by: FB Owens (Season 2-3), Gary Lewis (Season 4-BTTS)
An ally to the turtles with a scientific mind like Donatello and is often referred to as "LH".
- Aborted Arc: His desire to return to the Utroms as he noted in his debut episode is never brought up again since the Turtles lack the ability to contact the Utroms. Even when they do meet them again, Leatherhead is never depicted actively trying to go back with them as he originally wanted.
- Always Someone Better: Downplayed. He humbly admits that Donnie is his superior in regards to intellect, as well as conceding that Don did the majority of the work on the outbreak virus. He ends up being the Someone Better to Stockman of all people. Once he has access to Bishop's resources, he quickly develops a cure for the outbreak virus whereas Stockman was getting nowhere.
- Back for the Finale: After not appearing in seasons 5 and 6, he returns in season 7's "Wedding Bells and Bytes", where he attends April and Casey's wedding.
- The Berserker: After being experimented on and tortured by Bishop, this side of him will come out and you better hope you're not aligned with the Shredder or Bishop in any way.
- Berserk Button: Several:
- The Shredder. He's the one who is hunting down the Utroms, who raised him. When Leatherhead got his hands on him, he was completely destroyed. Also, do NOT say that you either work or have worked with the Shredder. Stockman learned that the hard way.
- Do NOT threaten to kill his friends. Marlin learned that the hard way.
- As he was tortured and experimented by Bishop, Leatherhead would lash out and attack him at every opportunity he gets.
- Beware the Nice Ones: Is for the most part a nice, easy going guy. Just don't hurt his friends, you especially don't want to be around him when he loses his temper.
- Big Damn Heroes: At one point, the Turtles are beaten up by Bishop's goons and are about to get gunned by them. Then Leatherhead shows up behind them. We hear slashes and screaming.
- The Bus Came Back: After not appearing since season 2's "What a Croc", he returns in season 3's "Worlds Collide" part 2.
- But Now I Must Go: He stays with the Turtles in early Season 3 following being freed from Bishop, but eventually decides that his temper is too volatile for him to continue living with them. He establishes a base in a nearby abandoned subway tunnel.
- Early-Bird Cameo: He made a brief cameo in "Secret Origins" part 2, where he was spotted by a soldier, before making his proper debut in "What a Croc".
- Emotional Bruiser: This version was quick to show off just how tender-hearted he is in addition to how tough he is.
- Genius Bruiser: Here he is not only intelligent but also well versed in various technical and scientific fields and therefore the Turtles and their friends (including Professor Honeycutt) find not only his giant strength but also his great intelligent helpful.
- Honorary True Companion: He's very close to the Turtles and Splinter but is prevented from living with them or joining their team full time due to the PTSD he suffered under Bishop which makes him prone to moments of serious instability. But whenever he's really needed, he'll always be there to lend them a helping hand.
- Interspecies Adoption: Is an alligator raised by Utroms.
- Load-Bearing Hero: At the end of "What a Croc", his lair begins to collapse. He holds the collapsing celling, giving the Turtles just enough time to escape with their lives, seemingly dying in the process. In later episodes, it's revealed he survived.
- Manly Tears: He is shown to openly weep on occasion when under significant duress... or when he attends Casey and April's wedding.
- Metamorphosis: From alligator to humanoid alligator.
- My God, What Have I Done?: Leatherhead says this almost word for word when he attacks Michelangelo in a fit of uncontrollable rage, leaving him unconscious and fearing him badly hurt/dead.
- No-Holds-Barred Beatdown: In "Exodus, Part I", Leatherhead finally comes face to face with the Shredder. Enough said.
- Sewer Gator: He was a pet alligator that was flushed into the sewers before he was mutated.
- Sixth Ranger: To the Turtles. He's often called in as extra support in their battles against Shredder and Bishop.
- Teeth-Clenched Teamwork: In "Good Genes" he nearly kills Stockman due to Bishop lying about having a cure for Donnie's mutation, but Splinter is able to convince him to stand down and work with Stockman for Donnie's sake. Leatherhead accepts and actually finds the real cure for the outbreak.
- Truer to the Text: His previous series' counterpart was notably a villain who antagonized anyone he saw as weaker. His 1987 incarnation was also not particularly bright. Starting with this incarnation, Leatherhead would only antagonize the Turtles due to misunderstandings and quickly became their friend akin to the original comics. This Leatherhead is also easily as smart as (or even smarter than) his Mirage comics counterpart, to the point that he rivals Donatello in terms of intellect (though he later confesses to being inferior to Don's smarts).
- Unexplained Recovery: Hun and Leatherhead both appear to fall to their doom in "Exodus, Part 1". They both appear later with no explanation of how they survived or what happened to them immediately after the episode. Granted, their fall was indoors and it is rather hard to determine how far they fell (and unlike the Gyoji, it is rather doubtful that the writers intended this to be their death).
- Unskilled, but Strong: He lacks any skill in unarmed combat, but he's sheer size and power means that for the most part he doesn't need it.
- What Happened to the Mouse?: He doesn't appear in Season 5, even with the threat of the Tengu Shredder and the fact that the Turtles summon almost every recurring character they can think of. He's later absent from all of Season 7 except the finale, despite the fact his technological savvy could've been of great use in recovering Splinter's data.
- You Can't Go Home Again: Leatherhead initially yearns to rejoin the Utroms, not aware they left Earth and their base of operations was destroyed.
Justice Force
Silver Sentry
Silver Sentry
TMNT's local Superman Substitute
Voiced by: Terrance Archie (Season 1-5), Marc Diraison (Fast Forward-Back to the Sewer)
Silver Sentry: I admire your good intentions, but this is a dangerous occupation.
One of Michelangelo's superhero idols and the leader of the modern-day Justice Force.
- Brainwashed and Crazy: Becomes an Unwitting Pawn to Dr. Malignus thanks to one of his mind-control bugs. Thankfully, Michelangelo is able to remove the bug from him.
- Canon Foreigner: He was created for this show.
- Captain Ersatz: Of Superman.
- Chest Insignia: A stylized bird—probably.
- Flying Brick: Goes with being a Captain Ersatz of Superman.
- The Leader: He leads the modern Justice Force.
- Leitmotif: Fittingly enough, he has a theme reminiscent of John Williams’ Superman theme.
- Superman Substitute: He's a Flying Brick, has an immensely altruistic nature, and well-liked by the public.
- Super-Toughness: Comes with being a Flying Brick.
- X-Ray Vision: Again, he’s a Superman Substitute. This is to be expected.
- The Worf Effect: Is casually swatted aside by the Triceratons (along with the rest of the Justice Force at the hands of their advanced weaponry) and the Tengu Shredder (who pulled a casual Punch Catch when Sentry attempted to attack him directly), despite being hands down the most powerful hero in the series.
Ananda
Ananda

Voiced by: Carrie Keranen
The daughter of two members of the original Justice Force, Ananda blamed the team for her mother's death and originally wanted revenge on the team. After being convinced by her father that her revenge was misplaced, she ends up joining the new incarnation of the team.
- Adaptational Superpower Change: In the comics her power was super strength, while here it's technopathy.
- Adaptational Villainy: In the original comic Dr. Dome was the one who sought out misplaced vengeance against the Justice Force, while she was the one to snap him out of it. Here it's the other way around.
- Ambiguously Human: Much like her father. She certainly looks human...with the exception of the dome under her helmet.
- Colour-Coded for Your Convenience: Domeoids that are under her control glow red, much like her dome.
- Heel–Face Turn: Started out as an enemy of the team in her first appearance, but went on to become one of its core members.
- Luke, You Are My Father: In the climax of "Return of the Justice Force", Ananda reveals to Dr. Dome that she is his daughter.
- Mini-Mecha: In "Return of the Justice Force", she uses her technopathy to control Dr Dome's mech. She's later seen in future episodes piloting it.
- Older Than He Looks: She appears to be in her mid twenties but based on Stainless Steel's comments about having carried around an old Justice Force Communciator for "almost forty years", she's presumably in her late thirties (unless Steel was counting the time when the team had been together before Ananda was born in that tally).
- Related in the Adaptation: In the original Mirage comics, the identity of her father is never revealed. Here, her father is Dr. Dome.
- Roaring Rampage of Revenge: In "Return of the Justice Force", it's revealed that she believes that the Justice Force is responsible for her mother's death, and uses the Domeoids to capture and eliminate the retired heroes.
- Superpowerful Genetics: She seems to have inherited her technopathy powers from her father.
- Technopath: She has the ability to control machines, just like her father.
- Uncanny Family Resemblance: She and Battling Bernice (daughter/mother) look identical, as in the comic books. Hell, Dr. Dome upon seeing her thinks she's Battling Bernice.

Nobody: Thanks to the politicians in your pocket, I'm nobody.
Ruffington: Then you won't be missed.
Ruffington: Then you won't be missed.
An unnamed cop who had his career placed in jeopardy when he started digging up too much dirt on Ruffington, who he was investigating. Unable to stand the corruption, he took on the identity of a masked vigilante to get through the red tape. He eventually joins the Justice Force in the fifth season.
- Adaptation Dye-Job: In the original comics, he wore a black and white costume (indicated from the cover of the issue he appeared in). In this series, the white parts are colored red.
- Badass Normal: He doesn't have any superpowers, but can hold his own just as well.
- Batman Parody: He is basically this universe's equivalent of Batman.
- Captain Ersatz: Like in the original comics, he serves as one of Batman, specifically Frank Miller's version.
- Dark Is Not Evil: Wears a costume, that is entirely black with exception of his hands and feet, which are red. He definitely has a sinister look, but he's on the good guy's side.
- Enemy Mine: In Season 5 he joins the Turtles’ army of heroes and villains banding together against the Tengu Shredder, and notably Ruffington is among Hun’s allies present.
- The Faceless: Any time he's seen without his mask his face is always obscured in shadows, so we never properly see what he looks like.
- Good Is Not Soft: He's on the good guys' side, but don't let that fool you. He's gonna use extreme measures to take out his opponents, even guns at one point.note In his next appearances, however, he stopped using them.
- Meaningful Name: After Ruffington ruined his career and personal life, he lost everything. In other words, he became a "nobody".
- Meaningful Rename: During his debut episode, he largely calls himself Nobody. However, after he foils Ruffington's weapons deal and leaves him to the authorities, the arms dealer asks him who he truly is. Nobody replies "somebody". In later appearances, he still goes by the "Nobody" alias, though.
- No Name Given: Aside from his superhero alias, his actual name is never revealed.
- Roaring Rampage of Revenge: His motivation in "Nobody's fool". After his career was put in jeopardy, he became a costumed vigilante, who would do anything in order to stop Ruffington and his illegal smuggling of weapons. After achieving his goal, however, he started operating as a superhero for New York City, and he would later become a member of the New Justice Force.

- Power Gives You Wings: She has butterfly wings.
- Recurring Extra: She never has any dialogue or characterization, but appears in most of the Justice Force episodes.

A former member of the original Justice Force, who would later join the team's second incarnation. His hair is made from metal and is capable of manipulating it.
- Meaningful Name: He's called "Metal Head" and his hair is made from metal.
- Prehensile Hair: His hair is said to be "fluid" and he can manipulate it. In "Return of the Justice Force", he's seen stabbing several Domeoids with it, while in his brief appearance in "Space Invaders" part 2, he uses it to walk and tries to break a Triceraton ship's windows.
- Spiky Hair: When he's in a civilian disguise and in his superhero form.
Green Mantle
Voiced by: Sean Schemmel
Real name: Al Gordon. He is a parody of Green Lantern if Green Lantern got his powers from a cape.
- Captain Ersatz: Of Green Lantern, specifically Hal Jordan. Al and Hal's names rhyme, and their costume and powers are very similar (save for the fact that Mantle wields a cape and Lantern uses a ring).
- Clothes Make the Superman: He was bestowed a super-powered cape from an alien tailor; this cape allowed its wearer to fly, have super strength, use the cape as a transforming weapon, and granted many other powers.

Steve: As real as this steel saucer on my noggin.
A former member of the Justice Force with a metal plate that gives him Super-Strength.
- Cool Old Guy: Despite being pretty old, he can still headbutt Domeoids with ease. And then, even before he was forced out of retirement, he was still a pretty cool old man, working at a comic book store.

Voiced by: Andrew Rannels and Sean Shemmel

Dr. Dome
Voiced by: Stuart Zagnit
A former member of the Justice Force, who left the team due to the Love Triangle between him, Stainless Steve and Battling Bernice.
- Adaptational Attractiveness: Okay, maybe attractiveness is abit of an overstatement, but let's just say Dr. Dome looks nowhere near as ugly as he was in the original comic.
- Adaptational Nice Guy: Unlike the original comic, where Dr. Dome was selfish Jerkass with a vendetta, he's portrayed as more sympathetic here.
- Ambiguously Human: He certainly looks human...with the exception of the dome on his head.
- Colour-Coded for Your Convenience: Domeoids that are under his control glow blue, much like his dome.
- Good All Along: He's initially believed to be controlling the Domeoids and ordering them to capture his former teammates. In reality, it's Ananda, who's controlling them.
- Love Triangle: He was in one with Stainless Steve over Battling Bernice.
- Meaningful Name: He's called Dr. Dome and has a giant dome on his head.
- Mini-Mecha: He pilots one in "Return of the Justice Force".

Utroms and Guardians
The Utroms
The Utroms
An advanced alien race that is connected to the origins of the Turtles. A group of them got stranded on Earth hundreds of years ago and since then, they only want to return to their home planet.
- Adaptational Late Appearance: The Utroms first appeared in the original comics in volume 1, issue 3. In this series, most early stories from volume 1 have already been adapted in season 1, while they make their debut at the end of said season.
- Alien Among Us: Obviously. A group of them crash-landed on Earth and, due to the primitive technology on Earth, had to wait in order of the technology on the planet to advance enough in order to return to their planet. During their time on Earth, they blended quite well in human society.
- Alien Noninterference Clause: The Utroms landed on Earth in medieval times. They strictly adhered to this to avoid skewing humanity's development. Once human technology had advanced enough, they started developing it to try and return home.
- Big Good: As a whole, the stranded Utroms more or less served as this in earlier seasons. Not only did they oppose the Foot Clan and the Shredder long before the Turtles and Splinter's creation, but they also were responsible for the heroes' creation, whose actions over the course of the series would lead to the downfall of Shredder and the Foot Clan.
- Cephalothorax: Their bodies resemble brains.
- Decontamination Chamber: After prolonged contact with the outside world, they have to go to one of these. Judging from the Utroms's reactions, it doesn't seem very pleasent.
- Good All Along: In "The Search for Splinter", the Turtles discover that the Utroms have kidnapped Splinter and put him in a pod. In reality, they rescued him and put him in the pod in order to heal his injuries.
- Glowing Mechanical Eyes: Their exosuits have these.
- Kangaroo Court: At the end of "Exodus" part 2, a group of Utroms act as judges during Ch'rell's trial and proceed to list every crime he has committed before banishing him to an ice asteroid. Despite the trope's name, this is arguably a subversion since Ch'rell is guilty as sin of everything the Utrom judges are condemning him for.
- Mobile-Suit Human: In order to blend with humans, the stranded Utroms salvaged some technology from their crashed ship and created such suits.
- Mythology Gag: One of them is named Krang, after the alien in the first cartoon loosely based on the Utroms. It's played for laughs as he's named and told to shut up in the same breath.
- Organic Technology: Some of their technology has shades of this.
- When the Turtles and Splinter get stuck in a trap from "Secret Origins", Donatello notes that the room has nerves and uses this to his advantage, literally by making the room sick and vomiting them.
- Pay Evil unto Evil: Stranding someone on a frozen planetoid to die all alone in a far-flung part of outer space might seem inhumanly cruel, but given the many, many crimes Ch'rell committed against Utroms, mutants and humans alike, the Utroms are frankly being lenient when they do this to him.
- Perfect Pacifist People: They are a pacifistic and scientific people. Fugitoid, when he is offered a new home on the Utrom's home planet, even remarks that he's thrilled to work with a race that will use his research for good. Subverted, as if they need to fight, they will fight. Also, there's Ch'rell a.k.a the Shredder.
- Really 700 Years Old: They have really long lifespans, which is indicated by both Mortu and Ch'rell, who have been on Earth since the times of Medieval Japan and haven't aged a bit.
- The Reveal: That the employees of the TCRI building are infact Utroms, and that the mutagen that transformed Splinter and the Turtles was a byproduct of their scientific attempts to return home.
- Skelebot 9000: Their exosuits (without any disguises) resemble skeletons.
- Starfish Aliens: They are small brain-like creatures who have small appendages.
- Technicolor Eyes: Their eyes have blue sclera and red irises.
- We Wait: In "Secret Origins", the stranded Utroms used their long lifespan to their advantage, waiting for Earth's technology to advance long enough and use it to return to their planet.

Voiced by: Dan Green

- The Captain: He was this before Ch'rell sabotaged his ship and crashed on Earth.
- Canon Foreigner: He was created for this series.

- Gone Horribly Wrong: Says this when the Turtles get trapped in the virtual reality program.
- Noodle Incident: In "Wedding Bells and Bytes", an Utrom informs Mortu that there is no sushi at the wedding, to which Mortu mentions that the last time he was near sushi he ended up smelling like soy sauce.

- The Promise: He promises the Fugitoid that they will somehow free the Turtles from the virtual reality program.
- Sdrawkcab Name: His name is "Utrom" spelled backwards.
- Strange Minds Think Alike: Both a past version of Mortu and Raphael have the same response to Ch'rell's threat: "Big talk, little slimeball."
- Tempting Fate: A rare "From bad to good" example. Mortu doesn't believe that the Turtles will be able to activate the internal fail-safe of the virtual reality program. They do.
Council of Three
Council of Three
Click to see their Utrom forms
Voiced by: Darren Dunstan (all of them)
Three high-ranked Utroms, who give advice to Mortu and lead the Guardians.
- Canon Foreigner: They were created for this series.
- The Dividual: They are nearly identical (even voiced by the same person), and the only thing that separates them is their different appearances.
- Finishing Each Other's Sentences: They all speak in such manor. An example from "The Shredder Strikes" part 1:Councilor 1: Find out—Councilor 2: What the Turtles—Councilor 3: Will do. If they—Councilor 1: Are with Saki—Councilor 1: We may be forced—All of them: To destroy them.
- Glowing Eyes: When they talk, their eyes glow.
- The Omniscient Council of Vagueness: They are the ones, who lead, or at least monitor, the Guardians. Played with, as they aren't actually evil and are in fact Utroms.
- Put on a Bus: After the "Secret Orgins" three-parter, where they return to the Utrom homeworld, they are never seen again (unless you count the recycled footage in "Exodus, Part 2").
The Guardians
The Guardians
An ancient organization, which was comprised of humans who were entrusted with the secrets of the Utroms. They seem to be the arch-enemies of the Foot Clan.

- Chuck Cunningham Syndrome: The Guardians were fairly prominent in season 1, aiding the Turtles in their battles against the Foot Clan. At the end of the "Secret Origins" three-parter of season 2, they get transported, alongside the Utroms and the Fugitoid, to the Utrom's homeworld, but (unlike both the Utroms and the Fugitoid) they never reappear again.
- Cool Shades: All of them wear dark shades. Even at night.
- Cool Sword: All of them have these and with them, they can defeat any Foot ninja they encounter. They even glow.
- Establishing Character Moment: In "Shredder Strikes" part 2, Leo is cornered by dozens of Foot Ninjas. Suddenly, a Guardian jumps down and proceeds to kick the Foot's butt.
- Lured into a Trap: The Guardian that Leo befriended, is lured to the Foot's HQ when the tower has seemingly reactivated. In reality, the Turtles wanted to get his attention and to ask him about the truth. When he says that he can't tell them the truth and leaves, the Turtles track him with a small tracking device.
- Men of Sherwood: Only one or two of the Utrom Guardian Ninjas have any dialogue or prominence, but when a whole detachment of them join in the battle against Shredder in "Return to New York Part III", they help win the day.
- Mysterious Watcher: In "The Shredder Strikes" part 1, two Guardians are watching Leo, who just met the Shredder for the first time.
- No Name Given: We never discover any of the Guardians' names. Not even the one that befriended Leo.
- The Omniscient Council of Vagueness: They are lead, or at least monitored, by "The Council". Played with, as they aren't actually evil and are in fact Utroms.
- The Reveal: In "The Search for Splinter", the Turtles realize that the Guardians are somehow connected to a company called TCRI, the company that created the ooze that mutated the Turtles.
- Samurai Ponytail: All of them have ponytails, but are more of a case of ninja-samurai combination.
- Samurai Shinobi: They are ninjas, who are loyal to their masters, the Utroms.
- Secret Test of Character: During the "The Shredder Strikes" two parter, the Guardians are monitoring the Turtles, seeing if they will accept Shredder's offer and join the Foot. When they discover that they rejected, a guardian helps Leo in a battle and introduces himself.
- Smoke Out: This is how the Guardian from "The Search For Splinter" part 1 leaves, when he can't tell the Turtles the truth.
- Undying Loyalty: To the Utroms.

Professor Honeycutt / The Fugitoid
Professor Honeycutt / The Fugitoid
Voiced by: Pete Zarustica
A scientist whose mind was accidentally transferred into a robot's body, and is forced on the run by groups who would use his inventions for their own purposes.
- Adaptational Late Appearance: In the original comics, he appeared as early as issue 5 of volume 1note . In this series, most stories from volume 1 (specifically the issues that were adapted into the "Shredder Strikes Back" two-parter and "The Return to New York" three parter) had been adapted in season 1, while Fugitoid makes his debut in "The Fugitoid".
- Badass Bookworm: Becomes one as the series goes on.
- Batman Gambit: Knowing the Triceratons and the Federation will relentlessly search and kill in order to obtain his teleportal, Fugitoid deletes the Teleportal plans and comes to Earth in "Worlds Collide" part 1, where he tries to surrender himself to them. If one of the sides captures him, he will upload a virus, that will cripple both sides' forces, which will force them to surrender. While this plan works with the Federation, the Triceratons realize this and use it to their advantage by destroying their helpless enemy...until Traximus' rebels come in and overthrow Zanramon.
- Bell-Bottom-Limbed Bots: Professor Honeycutt, a.k.a. The Fugitoid, falls cleanly under this.
- Brain Uploading: Thanks to a combination of lightning and his telepathic helmet, his mind was transferred into his robot's body.
- Disney Death: He sacrifices himself to cripple the Triceraton and Federation forces in the "Space Invaders"/"Worlds Collide" arc, and is given a space burial, but later returns several episodes later into the season.
- 11th-Hour Ranger: To the Turtles in late Season 3, assisting them in their final assault on the Shredder.
- Heroic Sacrifice:
- Pulls one in early Season 3 to cripple the war over his teleporter, but later returns alive and well.

- Just a Machine: Although it's not true, he is considered this by The Federation.
- The Professor: Obviously.
- Put on a Bus: In early Season 2 he leaves to live with the Utroms. At the end of Season 3, he returns to them and isn't seen again until the series finale.
- Took a Level in Badass: In the series finale, he's the very first of the Turtles' allies to leap into the fray against the Cyber Shredder's forces.
- Undying Loyalty: To the Turtles.Honeycutt: I am with you until the end.
- Unwanted Assistance: In the "Worlds Collide" three-parter, he's trying to surrender himself to the Triceratons now that he's wiped the data of his teleporter from his memory, and is annoyed that the Turtles are trying to save him from the warring aliens.
- Was Once a Man: A non-monstrous example. Honeycutt was once a human-looking alien scientist, who tried to free his robot companion when he entangled himself in wires. Due to a combination of his telepathic helmet and lightning, his original body was destroyed, while his mind was transported in his robot.
- Weaponized Teleportation: In both seasons 2 and 3, Honeycutt wants to completely defy this, as he has created a Teleportal that is wanted by both the Triceratons and the Federation, who would use it to conquer the galaxy by teleporting weapons of mass destructions to the cores of planets, which would result in the dead of untold millions.
Traximus
Traximus
Voiced by: FB Owens
Traximus: Raph, that is a rash, fool-hearty and extremely dangerous act. Count me in.
A Triceraton warrior who opposed Zanramon. Due to this, he was demoted and turned into a gladiator, forced to fight in "The Games".
- Bash Brothers: He becomes one with Raphael. Over the course of the "The Big Brawl" four-parter, they are put in a duel, in which Raphael won. Even then, Traximus took Raph for a drink and began to talk like good old friends. Traximus later helps Raph infiltrate Daimyo's fortress and discover why Splinter was imprisoned. In "Space Invaders" part 2, where the Turtles encounter Traximus for a third time, he jokingly asks them for a rematch. Raph is enthusiastic in meeting him again.
- Canon Foreigner: He was created for this series.
- Defeat Means Friendship: In "The Arena", he's defeated by Leo, who spares him. This act reminds him of what fighing with honor is, which makes him refuse to fight them later in the episode, thus becoming an ally of the Turtles.
- Expy: He's very similar to Maximus from Gladiator. Both of them are warriors who are turned into gladiators. He's also similar to Spartacus, as they both lead a rebellion. A succesful one in Traximus' case.
- Gatling Good: At the end of "World Collide" part 3, he's given a gatling gun by Mozar and destroys Zanramon's throne.
- Gladiator Games: He was demoted and forced to fight in the arena as a gladiator. He also participated in the Battle Nexus Tournament, though he wasn't there for just the battles, as he was looking for recruits for his Rebellion against Zanramon.

- Rebel Leader: In "Space Invaders" part three, it's revealed that he's leading a rebellion against Zanramon's regime.
- Rousing Speech: Two times:
- In "The Arena", he proclaims that Zanramon's regime is coming to an end.
- In "Worlds Collide" part 3, he succeeds in overthrowing him. He proclaims the beginning of a new era of peace and prosperity between the Triceratons and the Federation.
- Rule of Symbolism: In-Universe. He destroys Zanramon's throne, symbolising the end of Zanramon's regime and the return of honor to the Triceraton society. Before he does so, he has this to say:Let this be a symbol of things to come. From this day forward, none shall sit upon the throne of the Triceratons!
- Thrill Seeker: His quote from "Battle Nexus" part 3 suggests he is one. It's the quote for his character page.
- Totem Pole Trench: In "The Big Brawl" part 4, him and Raph reach the dungeon where Splinter is in such a manner.
Other Gladiators
Paz, Fists, the Twins, and Monkey Face.
Voiced by: N/A
Prisoners of the Triceraton Republic and unwilling participants in the Gladiator Games, along with Traximus and later the Turtles.- Always Identical Twins: The Twins are completely identical.
- Defeat Means Friendship: They start out fighting the Turtles and are beaten by them. Afterward, Monkey Face, Fists and one of the Twins share some of their food with the Turtles when Gruell the jailer tries to starve them, and all five of them refuse to fight them to the death in the arena.
- Green and Mean: Paz has green skin and the meanest expression of the five. While he does become an ally of the Turtles, he's also less friendly to them than the other gladiators.

- Manly Facial Hair: Monkey Face has an imposing gray beard that helps sell his role as an aged and experienced gladiator.
- Multi-Armed and Dangerous: Fists has four very muscular arms and uses them to wield a hammer with great force.
- Only Known by Their Nickname: With the possible exception of Paz, it's doubtful if any of them were born with the names the fans know them by.
- What Happened to the Mouse?: Fists isn't seen during the flashback of the others escaping, although Traximus implies that all of them made it. It's also unrevealed if the others join Traximus's resistance movement afterward.
Renet
Renet
Voiced by: Liza Jacqueline
An apprentice "Timestress" of Lord Simultaneous , whose job is to oversee and protect the timestream.
- Adaptational Modesty: No Cleavage Window for her.
- Astonishingly Appropriate Appearance: She's the current timestress and apprentice of Lord Simultaneous, and her outfit has clocks all over it.
- Character Development: She's largely much less of a whiny jerk in her second appearance, due to having gotten some experience with the Time Scepter.
- Damsel in Distress: For most of her appearances in "Time Travails" and "The Return of Savanti Romero" part 2, she is captured by Savanti Romero and the Turtles need to rescue her.
- Dissonant Serenity: In "Time Travails", she calmly explains how the "Orb of Hindsight" shows important events, before something horrible happens.Renet: Sometimes it's a bummer, 'cus everyone is like, about to be horribly destroyed and stuff.
- The Ditz: Renet is shown to be quite a scatterbrained person who came to her friends with good intentions, but with little practical skill she caused some problems across space and time.
- Forgotten Phlebotinum: She's completely and inexplicably absent from the Fast Forward season, where the Turtles are stuck in the future — because if she'd appeared she could instantly have fixed their predicament.
- Human Aliens: She looks like a human, but she comes from the 79th dimension.
- Most Common Superpower: She is notably endowed as well.
- Nice Job Breaking It, Hero: Already in her first appearance, Renet was sentenced to dusting in Lord Simultaneous library because she had accidentally reversed the evolution on a planet of giant worms, and got a six-week penalty. Quickly, she tried to use the Time Scepter to get though her sentence quickly. However, this played into the hands of Savanti Romero, who caused the arrival of the scepter with black magic.
- The Load: Due to not knowing how the Time Scepter works, and not really having any combat prowess, she's largely useless in a fight. Even the Turtles grow exasperated with her in her first appearance.
- Time Police: One in training, anyway.
- True Blue Femininity: Her outfit is mostly blue and it matches her Innocent Blue Eyes.
- Valley Girl: Her speech is this.
Miyamoto Usagi
Usagi
Voiced by: Jason Griffith
The guest-starring character from the comic Usagi Yojimbo.
- Bash Brothers: With Leonardo. The two became very fast friends, and Usagi even goes to the point of calling Leo brother during "The Real World" parts one and two. It helps they have the same weapons and that Usagi's just a more cynical version of him.
- Big Damn Heroes: In "The Real World" part 1, when Leo, Tomoe Ame and Noriyuki get ambushed by Hebi's minions, Usagi and Gennosuke come just in time to rescue them.
- Crossover: The characters and setting of Usagi Yojimbo show up more than once in the series.
- Early-Bird Cameo: He shows up in a flashback detailing how Drako tried to kill Splinter for defeating him, and helps Splinter.

- Gladiator Games: He participated in the Battle Nexus Tournament alongside the Turtles, Splinter and Gennosuke.
- Gratuitous Japanese: Often uses this.
- Hero of Another Story: The Turtles go on adventures with him and sometimes even encounter a few of his friends and battle some of his enemies. And even though Usagi's world isn't explored too much in the series, it's pretty clear that Usagi keeps himself busy as the main hero of his own world filled to the brim with his own allies, his own rogues, and even more of his own adventures.
- Honorary True Companion: He's a true friend to the Turtles, and to Leonardo in particular, but because he lives on another earth and has many of his own duties as a hero there, he can only occasionally team up with the Turtles on adventures.
- Let Us Never Speak of This Again: In "The Real World" part 1, he is forced to infiltrate Hebi's fortress with Leo, acting like ninjas in the process. While he does respect the Turtles, he doesn't really like ninjas.Usagi: Ugg! Ninja garb! I feel like I am cloaked with dishonor! We will speak of this matter to no-one!
- My Greatest Failure: Regards being Forced to Watch his master get killed in battle next to him as this.
- Rōnin: He was a samurai until his master was killed before his eyes, so by the time the turtles first meet him, he is an honorable ronin.
- Samurai Ponytail: A variation. His ears are tied together.
- Truer to the Text: Unlike the 1987 cartoon, which called him Usagi Yojimbo, this adaptation refers to him as Miyamoto Usagi, his name from his original comics.

- Back for the Finale: He reappears in "Wedding Bells and Bytes", where he attends April and Casey's wedding.
- The Bet: To the point of a Running Gag. In "Тhe Big Brawl" part 3, he wants to make a wager with the Turtles on who's gonna win the Battle Nexus Tournament. In "The Real World" part 1, he once again wants to make a wager with Lord Noriyuki on what would be the outcome of their mission:Gen: I don't suppose you're interested in a small wager on the outcome of this little adventure.
- Bounty Hunter: Is called one by Kojima in "Samurai Tourist", but he's never actually seen doing any bounty hunting. After Kojima's defeat, he explains that he will be able to share a rich bounty when him and Usagi turn Kojima over to the authorities, but that's about it.
- Dual Wielding: In "The Real World" part 1, he carries two katanas.

- Action Girl: She can handle Moriah quite well in a battle, though she needed some help when her opponent brought her servants.
- Adaptational Late Appearance: In the original comics, she appeared way back in volume 1. In this series, most of the stories from the first volume have already been adapted in seasons 1 and 2, while Jhanna makes her debut in season 4.

- Laser Blade: She uses one of this in her fight against Moriah.
- Literal-Minded: When her arm is injured and Donnie asks if she wants him to "look at it", she doesn't understand how looking at it will heal. Being an alien, it's justified.
