Purple Dragons

As a whole

A New York street gang consisting of mostly teenage thugs, thieves and killers.

All There in the Script: From just watching the episodes, most of the Purple Dragons' names are never revealed or spoken on-screen. Their names, however, could be found in external media.^note
Ascended Extra: Like the Shredder, the Purple Dragons were one-shot characters that appeared in the very first issue of the comic book, though unlike the Shredder, it would be decades before they became a permanent part of the Turtles' rogues' gallery.
Enemy Mine: In the fifth season finale, they fight alongside the Turtles, their allies, Karai’s Foot Clan, and the EPF against the Tengu Shredder.
Equal-Opportunity Evil: The Purple Dragons are shown to have a few females in their ranks. They also don't seem that bothered about the idea of Angel joining them.
Pipe Pain: Most of the Purple Dragons are seen carrying pipes as weapons.
Out of Focus: They appeared often in early episodes of Season 1, but their prominence quickly declined. In the "City at War" three-parter of Season 2, they return as one of the factions that fights for control over New York. In Season 3, they only appear once in a Christmas Episode. Subverted when Hun returns and transforms them into a competent criminal organization, thus becoming more prominent in Season 4.
Overshadowed by Awesome: They are quite capable in a fight, but as the series introduced aliens, robots and so on, this trope inevitably took into effect. Season 4 subverts this when they are turned by Hun into a criminal organization.
Starter Villain: The very first opponents the Turtles fought.
Tattooed Crook: Most, if not all of them, have tattoos.
Took a Level in Badass: They started out as a street gang, although they had connections with the Foot Clan, they were the Starter Villains the Turtles easily took care of in the first episode before facing off the Foot, who give them a run for their money. By season 4, Hun manages to turn the gang into a legit criminal organization and by the final season and Turtles Forever they were one of the biggest threats in the show, to the point that their headquarters are now comparable to the Shredder's.
What Happened to the Mouse?: Sunny, Two Ton and the rest of Hun's old Mooks are rarely if ever seen among the new, organized crime style Purple Dragons that Hun forms after Shredder's defeat.

John/Johnny

Johnny

Voiced by: Eric Stuart

Johnny: You're going down, freaks! Nobody messes with the Purple Dragons! Especially wearing stupid turtle costumes!

The ringleader to the first group of Purple Dragons the Turtles run into, who were attempting to rob an armored car. After the Turtles thwarted the robbery, he is seen reporting his failure to Shredder, who kills him for botching the job.

Canon Foreigner: Created for the show.
'80s Hair: Has some of the wildest hair of the Purple Dragons.
Killed Offscreen: Is last heard screaming before he is presumably killed by Shredder.
Red Shirt: Killed by Shredder.
We Hardly Knew Ye: Is introduced and killed in the same episode he appears in. He mostly exists to give an introduction to the Shredder, and demonstrate Shredder's unforgiving nature.
You Have Failed Me: Shredder does not take his failure lightly.

Hun

https://static.tvtropes.org/pmwiki/pub/images/hun054.jpg

Voiced by: Greg Carey (Seasons 1-4, Back to the Sewer), David Zen Mansley (Season 5, Fast Forward)

Hun: Oh, crud.

Real name: Hunter Mason. A hulking, tattooed gangster who serves as the leader of the Purple Dragons street gang and Shredder's second-in-command, at least until Karai comes along.

Animorphism: To a mutant turtle, in Turtles Forever.
Arch-Enemy: To Casey in most continuities. He killed Casey's father.
Badass Normal: A borderline case. He's never explicitly stated or shown to have any superhuman or mutant abilities, but he's still capable of giving a hard time to the Turtles on his own. And some of his feats of strength and durability do appear to skirt the lines of being borderline superhuman (or peak human at the very least).
Badbutt: His Character Catchphrase is clearly a replaced swearword, and he gets in as much street gangster as he can in a kids' show. His favored gun is a rocket launcher, which is a bit more kid-friendly than small arms and lets him actually hit something more often.
Bare-Fisted Monk: Hun's fists are his main weapons.
Brains and Brawn: The Brawn to Stockman's Brains. At least when both worked for the Foot.
Breakout Villain: He was originally created as just muscle for the Foot, but ended up well-liked for his surprising amounts of characterization, landing him not just more story prominence, both as an enforcer and one of the antagonists of Season 4, but eventually became part of the original Mirage comics, and a franchise mainstay.
Brought to You by the Letter "S": In the final season, he wears a belt with a dragon on the buckle, that looks like the English alphabet "S" written backwards. Once he mutates into a hulking humanoid turtle, he starts resembling Slash, making the belt buckle with the backward "S" appropriate.
The Brute: He is not stupid, but still, he is the Shredder's biggest and strongest enforcer.
Cain and Abel: Given that he views the Shredder as something of a father figure, he is essentially the adoptive brother of Karai, but he absolutely despises her and tries to have her killed many times. In Rogue in the House, Part 2, he manages to capture Splinter and forces the Turtles to surrender, but when Karai is tasked to execute Leo and his brothers, Hun sets Leo free and tells him that he might spare Splinter if he manages to take Karai out, indicating that he hates Karai more than he hates the Turtles, which is saying a lot. When he is tasked to rescue Karai from Bishop, he does so very reluctantly and because doing so would redeem him in the Shredder's eyes than out of genuine empathy towards her and even briefly gloats how he always wanted to see her dead but now he must rescue her.
Canon Character All Along: Implied. In Turtles Forever, he mutates into a large mutant Turtle with spikes on his body, which coupled with his Purple Dragons belt buckle resembling a backwards "S", suggests that he's a 2003 series version of 1987 villain Slash, albeit never explicitly referred to as such.
Canon Immigrant: He was originally created for the 4Kids show, but got popular enough to be adapted back into the comics, and later introduced (though considerably different) in the Nickelodeon cartoon. A slightly more Truer to the Text incarnation of him also appears in the IDW comics, though he is still a little different from the 2003 version.
Character Catchphrase: "Oh, crud"
Character Development: While initially very loyal to the Shredder, after learning about him being an alien, he leaves the Foot Clan and sheds a lot of his brute tendencies to turn the Purple Dragons from a petty gang of thugs into a lucrative crime organization, pulling off very successful heists in the process.
Charles Atlas Superpower: His strength, speed and durability are quite impressive for a supposedly normal human.
Closet Geek: He loves an MMORPG named SuperQuest. He has no problem admitting this to one of his unfortunate underlings, who stumbles upon him when he is enjoying the game. But he threatens never to reveal this to anyone. To quote the man himself:
"That's right, I'm a hardcore gamer. Have been for years! Tell anyone and I'll rip your tongue out!"
Deadpan Snarker: He often makes quips during fights and mocks Karai and Stockman using witty comments.
Hun: (Attacking Leo) Trust me, this is gonna hurt you a lot more than it hurts me.
The Dragon: To Shredder, though he eventually became Co-Dragons alongside Karai.
Dragon Ascendant: When Hun finds out Oroku Saki is actually an alien named Ch'rell, he leaves the Foot Clan, and does a complete makeover of the Purple Dragons, transforming them from simple street thugs into a veritable army that pulls off some very high risk and high reward theft jobs from multinational corporations and even the military.
- However, come Turtles Forever after he gets mutated into a turtle, he willingly decides to get Demoted to Dragon and serve Ch'rell once again.
Dragon with an Agenda: In Turtles Forever, after getting mutated into a humanoid Turtle, he goes back to serve Ch'rell, but his ultimate goal is revenge. He makes it clear, once the Turtles survive Ch'rell's atempt to kill them, that he doesn't care about the Shredder, he just wants to kill the Turtles. However, he lets go of his grudge when he realizes that Ch'rell is trying to wipe out the entire mutliverse and with his dying breath, asks the Turtles to stop him.
Dumb Muscle: In Season 5, and his Season 6 cameo, he's a childish buffoon. The rest of the time, he's a subversion: He has the muscle and looks the part, but he's actually fairly smart and a capable leader.
Empowered Badass Normal: In Turtles Forever.
Enemy Mine:
- In Season 3, he forms an uneasy working relationship with Stockman since after numerous failures, he finally understands how much it sucks to be on the Shredder’s bad side. They even work together on one occasion to try to kill Karai and Chaplin, their prospective replacements. That said, they still hate each other for all the misery they’ve caused each other and they inevitably turn on each other the first chance they get.
- In Season 5, he and the Purple Dragons are among the many heroes and villains who fight alongside the Turtles to defeat the Tengu Shredder.
Evil Counterpart: His Sibling Rivalry with Karai is like a dark mirror to that of Raph and Leo. While Raph is able to ultimately accept that Leo is the leader and gets along with him, Hun absolutely refuses to serve Karai. Fittingly enough, he transforms into Slash, after coming into contact with the 1987 universe mutagen and 2003 Raph.
Evil Is Bigger: He is by far the biggest and tallest major human villain, with his official height being 7'2" and his Charles Atlas Superpower allows him to trade blows with Triceratons and Leatherhead almost effortlessly.
Evil Sounds Deep: He has a pretty darn deep voice.
Expy: After becoming a huge, fanged, grimacing mutant turtle covered in spikes he's pretty much Slash in all but name.
Fantastic Racism: He despises non-humans after becoming an enemy of the Turtles. When Ch’rell is unmasked, he cuts ties with the Foot, disgusted that he was serving an Utrom (who he had also been led to believe were evil aliens). He eventually comes around to respect his former boss by the time of Season 5, but still refers to him as a disgusting slug. Call it karma, when he turns into a humanoid Turtle himself in Turtles Forever.
Hun: Do you know the thing I hate most in all the world? Turtles! Now I look in the mirror all I see is you! AND I HATE YOU EVEN MORE!
Fat Bastard: Subverted as he's all muscle, but he occasionally gets jokes to this end from the Turtles.
Flanderization: His portrayal in Season 5 and his cameo in Season 6 play up his more buffoonish side, and reduce him to a childish, more traditional brute of a character. It’s dialed back in Season 7.
Forgiven, but Not Forgotten: In Season 4, despite their history, Karai invites him to the opening of the Oroku Saki Memorial Library, and he accepts. They then have a completely civil conversation and go their separate ways peacefully.
Genius Bruiser: He is extremely smart, and uses his brains and brawns to his advantage. He single handedly turned the Purple Dragons from a street gang into a powerful criminal organization by season 4.
Gold-Colored Superiority: In the Back to the Sewer season, after he successfully turns the Purple Dragons gang into a crime organization, he starts wearing a gold fingerless glove with gemstones, kind of like a fingerless Infinity Gauntlet.
Guilty Pleasures: In-show variation with Hun. Running the Purple Dragons is one thing, but who would've thought he plays the same MMORPG that Mikey does? Not to mention he, unknowingly, met the Turtles in it and helped them get Splinter's data bits.
Hidden Depths:
- In Season 1, he comes off as a hulking brute, but shows very strong strategic capabilities, such as anticipating Raphael would escape and lead the Foot Clan right to the Turtles' lair in "The Way of Invisibility". These strategic capabilities would become much more pronounced in Season 4, after turning the Purple Dragons into a powerful organization, with several successful heists to their name.
- Back to the Sewers reveals that he's a gamer.
Karmic Transformation: In Turtles Forever, he ends up mutated into a Slash-esque Turtle after being in contact with both 2003 Raph and the old cartoon's Mutagen. To say he doesn't take it well would be quite an understatement.
Large and in Charge: A tremendous mountain of a man who's stated to weigh in excess of 500 lbs and the leader of the Purple Dragons.
Leitmotif: A deep, sinister guitar riff.
Lightning Bruiser: Don't let his size fool you, Hun is astonishingly fast—more than fast enough to be a match for the turtles.
Most Gamers Are Male: Size doesn't seem to matter for him.
Out of Focus: In Season 5, he only appears in the season finale due to the focus on the Turtles' war with the Tengu Shredder.
Pet the Dog: In Season 7, believing the Turtles are random players online, he amicably gives them first dibs on the treasure so they can get Splinter's data, and returns Mikey's wish that they could be friends in real life. This is an act of pure friendliness he didn't have to do whatsoever, but it's the nicest thing he's ever done.
Punctuated! For! Emphasis!: Is it any surprise that Hun has at least one moment of this? Hun: "Arrrrrgh! Go away! WE! PLACED! NO! ORDER!"
Rank Scales with Asskicking: One of the two constants about him is that he always is the leader of the Purple Dragons, and the strongest in the gang.
Scars Are Forever: Hun sports a trio of matching scars on his face, courtesy of a pre-mutation Splinter.
Sleeves Are for Wimps: He very rarely wears any thing with sleeves.
Smarter Than They Look: He looks like a big, dumb, brute, but he is a lot smarter. He managed to lead the Purple Dragons and turn them into a legitimate and powerful criminal organization following the Shredder's defeat.
Strong and Skilled: Barring his low showings where he gets taken out easily like a chump, Hun is presented as a fighter who's brutally strong enough to smack Karai around with a support beam and skilled enough in the martial arts to really give a hard time to all the Turtles and at one point, defeat and capture Splinter off-screen in "Rogue in the House" during some of his more flattering portrayals.
Strong as They Need to Be: Tends to go back and forth in how skilled and powerful of a fighter he is. Sometimes he'll be really powerful, to the point where he can take down multiple Turtles at once. Other times a single Turtle like Leonardo or Raphael will be able to take him down. In some episodes he'll be portrayed as The Juggernaut and it'll take a lot to bring him down. Then in other episodes, he'll get taken out easily in a humiliating fashion. How competent and dangerous of a fighter he is will always vary from one episode to another.
Tattooed Crook: He sports twin tattoos of the Foot and Purple Dragon symbols, removing the former after he leaves the organization for good.
Took a Level in Badass: In Season 4, Hun transforms the Purple Dragons from a petty street gang working for the Foot into a far more sophisticated organization operating on its own.
Undying Loyalty: He is this for Shredder, even before he finds out he is an Utrom. In fact, he reenters his service in Turtles Forever after the latter is brought back to Earth.
Would Hit a Girl: He was willing to hit April, hoping that losing her would cause the turtles to lose their fighting spirit. In "City at War, Part 3", Hun smacks Karai around with a support beam.

Dragon Face

Dragonface

Voiced by: Cedric Leake

A recurring Purple Dragon who acts as their second-in-command.

Dirty Coward: In Fallen Angel, after his gang is confronted by the Turtles and Casey, he orders his men to attack, while he himself hides in a nearby store. He also is visibly terrified when Hun returns in City at War, Part 2, after trying to take over as the leader. Hun quickly tosses him away like a ragdoll.
Dragon Ascendant: He proclaims himself as the new Purple Dragons' leader in "City at War, Part 2." This is defied by Hun.
Only Known by Their Nickname: His real name is never revealed.
Right Behind Me: He proclaims himself as the new Purple Dragons' leader, just as Hun is listening to him from above.
Tattooed Crook: Has a giant Dragon tattoo on his face.
What Happened to the Mouse?: After the "City at War" three-parter, he's never seen again.

Two Ton

Voiced by: Ted Lewis

The brawniest member of the original Purple Dragons gang.

Batter Up!: Seems to carry a bat.
Chained by Fashion: Has a large chain beneath his stomach.
Demoted to Extra: He seems to be John's Number Two in the first episode but is a pretty minor Mook after John is replaced, save for in "The Christmas Aliens".
Meaningful Name: A ton is a measuring unit for how heavy something is^note and he's probably the fattest member of the Purple Dragons.
Perma-Stubble: He always has a somewhat unshaven chin.
Stout Strength: He has a pretty thick stomach, but is a stronger fighter than most of the Purple Dragons.

Spike

Voiced by: Eric Stuart

The Bait: In "The Way of Invisibility", Spike and two other Purple Dragons spray graffiti depicting a Purple Dragon eating four turtles in order to draw out Raphael to be captured by the Foot Tech Ninjas.
Batter Up!: Spike usually wields a baseball bat or two in his fights against the Turtles and Casey.
Evil Redhead: Spike is a red-haired Gangbanger who steals from charity and tries to beat Casey to death while he's unconscious.

Spuds

Voiced by: Brian Mallard

The leader of the Northampton branch of the Purple Dragons.

Adaptational Villainy: In the original comics, he was a thug who was a part of Sid's gang. In this series, he's the leader of the Northampton branch of the Purple Dragons.
Evil Debt Collector: Spuds smugly holds April and Casey at gunpoint and ransacks the Jones farmhouse while trying to collect on the gambling debt Casey's cousin owes him.
Oral Fixation: Spuds is a toothpick-chewing thug.
The Precious, Precious Car: He really, really, really likes his car. He likes it so much that when Casey threatens to shoot it if he doesn't leave their farmhouse, he immediately leaves.
Smug Snake: Spuds spends most of his screen time smugly holding Casey and April at gunpoint and bragging about how the Purple Dragons aren't just street punks and bookies anymore, but he's easily defeated by April in a fight. He also frantically promises to leave for good when Casey threatens to shoot up his Cool Car.

Sunny

Ascended Extra: Sunny has no audible dialogue until his final appearance, where he leads Spike and Two Ton in hijacking a truck full of toys meant for charity.
Combat Pragmatist: He tries to hit Angel, a much younger girl, from behind during a fight at the gang's clubhouse.
Would Hit a Girl: In "Fallen Angel", he's the first one to step in the ring and fight Angel, a girl much younger than him.

Independent villains^note in order of introduction

Baxter Stockman

https://static.tvtropes.org/pmwiki/pub/images/2617364452_ef286fdef5_opng.png

One of his many, many forms.^{For some of the others...}

Voiced by: Scott Williams ^{Foreign VAs}Arnaud Léonard (FR)

A Mad Scientist and creator of the Mouser robots. While he sold them off as a means to rid the city of the rat problem, he was really using them to rob banks while under the Utrom Shredder's employ.

Adaptational Angst Upgrade: The original comic Stockman reveled in being evil, to the point where he deliberately turned himself into a cybernetic juggernaut. In the 1987 cartoon, the worst he suffered was bring accidentally turned into a mutant fly and eventually trapped in another dimension. Here, it's made very clear his time under Shredder is absolutely miserable, he loses his human body unwillingly, and the trauma takes a toll on him both physically and mentally.
- In all honesty, this Stockman would probably find being a mutant fly mercy compared to losing body parts to the point of just being a brain in a jar.
An Arm and a Leg: ...and an eye, and another arm and another leg and so forth...until he's reduced to a literal Brain in a Jar. A lot of it comes from Shredder living up to his threats of punishing him for his failures.
Arc Villain: For the Mousers arc, which composed the first three episodes of the series. Shredder may be his financial backer, but Stockman is the creator of the Mousers and is responsible for destroying the turtles' first home.
Ascended Extra: He's a rather minor antagonist in most major TMNT incarnations, but ends up being one of the most recurring and plot-critical villains as the series goes on.
Back from the Dead: In "Insane in the Membrane", Stockman dies when his new human body plummets helplessly into the river. A few episodes later, Bishop revives him, as he still needs his brain for his work.
Badass Bookworm: In his more powerful mechanized suits, Stockman proves he can put up a fight against the Turtles. He once forced the Shredder himself to briefly team up with them to take him down.
Bad Boss: He fully intended to murder April when she discovered the Mousers' true purpose. Sure, he's almost never in a position of authority again in the series, but this is pretty bad, and it is a small piece of a character so generally unlikeable that him being increasingly mutilated over the series' run (ironically as punishment for repeatedly failing the Shredder) elicits little in the way of sympathy.
Big Bad Wannabe: He really seems to want to be taken seriously as a criminal mastermind, but never manages to get very far in the process.
Brains and Brawn: The Brains to Hun's Brawn. At least when both worked for the Foot.
Body Horror: In "Insane in the Membrane", after four seasons of losing body parts, Baxter Stockman finally obtains a new body via cloning. Soon enough, however, he discovers that it's unstable, as his limbs start deteriorating and melting off. His mind had gone with it before being retrieved and placed back in his jar.
Brain in a Jar: By mid-season 2, his punishments from the Shredder and Hun have become so severe that he's been reduced to this, and he stays this way for the rest of the series. After his Heel–Face Turn in Fast Forward, Bishop implies that getting him a new human body will be easy.
Break the Haughty: Pretty much his entire CAREER is this, but "Insane in the Membrane" is where it really sinks in.
Butt-Monkey: He loses everything, gets slowly cut apart and has to replace his gradually increasing missing body parts with cybernetic parts, then transfers his mind into a clone body which degenerates, causing him to go insane and die. Then he gets brought back as a Brain in a Jar, unable to even have peace in death.
Can't Kill You, Still Need You: Deconstructed badly. His employers find his intellect crucial, but his insufferable personality means they are all too willing to abuse him and mutilate him as long as his brainpower is still intact for use. Eventually he's hacked away until he's a brain in a jar and eventually becomes a full-on Death Seeker over time. Even when he's killed, his enemies bring him back to use his intellect again for their schemes, essentially making Stockman wish he had been killed ages ago and begging to be put to rest.
Chronic Backstabbing Disorder: He frequently attempted to sabotage the people working with him, generally to make himself look better, or because he wanted revenge, though considering the abuse the Shredder and Hun inflict on him it's rather understandable. He cuts it out after being hired by Agent Bishop, for the most part.
Clone Degeneration: Within a week, Stockman's new human body deteriorates.
Composite Character: He is Baxter Stockman and starts out the same way he did in the original comics, but him eventually being reduced to a disembodied brain who needs an android body to move around, makes him similar to Krang from the 1987 animated series.
- His status as a disembodied brain (with only one eye and a spine) in a tank also brings Mutagen Man to mind.
Corrupt Corporate Executive: He was one before his body kept getting destroyed.
Deadpan Snarker: He often makes sarcastic remarks towards everyone, including the Shredder, which makes him a Servile Snarker as well. Even in the Bad Future of "Same as it Never Was", he maintains his sense of humor.
Oroku Saki: I do not tolerate failure.
Baxter Stockman: Which is why you would make a lousy scientist.
Death Seeker: Eventually after everything that happens to him he has enough of his miserable life and wants to die, but he's not even allowed to die because Bishop still needed him.
Determinator: He never seems to lose his smug edge or ability to concoct new schemes, no matter how many limbs get cut off, up to and including his entire body. Repeatedly. The Black Knight would be impressed.
Earn Your Happy Ending: Surprisingly, yes. It takes well over a century to happen, but Stockman finally catches a break in the Fast Forward episode "Head of State" where genetics research has advanced enough that Bishop can grant him a new body that won't fall apart like the last one, and his new Mousers are even commissioned by the Department of Agriculture, so his work can do some good for a change.
Even Bad Men Love Their Mamas: "Insane in the Membrane" reveals he did love his mother and her death haunts him.
Evil Genius: He's a scientific prodigy that uses his work for evil.
Evil Gloating: He is prone to doing this, which rarely works out for him:
- In "Return to New York, Part 3," just about every word out of his mouth is either bragging about his intellect or trash-talking everyone around him. He particularly loves reminding Shredder how his money paid for all of Stockman's gear. It bites him in the ass when he brags that each component of his Powered Armor has its own backup power source... which allows Donnie to realize that the Arm Cannon that was lopped off earlier still works.
- In "What a Croc!", he's successfully convinced Leatherhead that he's an ally and the Turtles are his enemies. He would have won right there, had he not decided to recall how many times the Turtles defeated him while he was working for the Shredder while he has them at his mercy, which exposes his true colors to Leatherhead and puts him at the receiving end of the croc's Unstoppable Rage.
Evil Is Hammy: Especially when he loses his sanity in "Insane in the Membrane".
Fatal Flaw: Pride. Stockman is incapable of seeing any flaws in his genius or knowing to quit when he's ahead that he's constantly blindsided by his opponents time and again when they take advantage of his hubris to defeat him. While he is indeed a genius, he never thinks to put it to use in less destructive ways and always tries to avenge any slights against him when it would've been better to leave well enough alone and cut his losses.
Fingore: Occurs to him in "Insane in the Membrane" as a result of his new body's degeneration.
Four Eyes, Zero Soul: In most continuities, he wears glasses.
Genius Bruiser: Particularly in "Insane in the Membrane", where he gets a new Super-Soldier body and is able to hold off both the Turtles and Casey. Keep in mind, he did this while said body was decaying.
Heel–Face Turn: Is eventually convinced to repent in Fast Forward and joins the reformed Bishop.
Hoist by His Own Petard: In "Return to New York". He's Crazy-Prepared with his Power Armor, including a back up power supply for each component in addition to the main power source. Donatello takes this as an understanding that a severed Arm Cannon should still be fully functional. Cue a hilarious Oh, Crap! from Stockman before Don blows him up with his own weapon.
Hypocrite: He calls mutants like the Turtles "stupid freaks". This coming from a talking head in a robot body. This version is notoriously vain, so it fits him perfectly.
I Just Want to Be Normal: He desperately wants to be restored to a human form.
Implacable Man: Lampshaded by Leonardo and Shredder:
Leonardo: What do we have to do, to stop this guy?
Shredder: I have asked myself that question many times.
Ineffectual Sympathetic Villain: He's actually quite competent when he sticks to his lane of inventing and science, but Stockman really gets the short end of the stick when he attempts to outwit his superiors. His increasing mutilation and dwindling sanity makes it hard to not pity him.
Inferiority Superiority Complex: While he has a massive ego, "Insane in the Membrane" reveals he has some serious self-esteem issues.
Insufferable Genius: Much to the chagrin of everyone around him. Shredder only puts up with him because he's useful. Hun is quick to note a benefit of having Stockman as a Brain in a Jar is that the volume for his voice can be turned off. When reviving him to continue his work on a cure for the mutant outbreak, Bishop openly admits he could do without Stockman's personality.
Joker Immunity: He's survived multiple apparent deaths. Leonardo even lampshades it upon Stockman's death in "Insane in the Membrane", pointing out that he's come back from worse and "only time will tell" if it's really the end of him; sure enough, Bishop soon revives Stockman.
Killed Off for Real: Subverted. Despite his Joker Immunity, his death in "Insane in the Membrane" was the real deal. Bishop explicitly raises him from the dead this time.
Large Ham: Almost ever bit of his actions and dialogue are a show of his arrogance.
Leitmotif: A bombastic orchestral piece that highlights his Mad Scientist nature.
Mad Scientist: Emphasis on the "Mad".
Mini-Mecha: Uses one in "Return to New York, Parts 2 and 3".
Nice Job Fixing It, Villain: His efforts against Shredder have come to the Turtles' aid a few times;
- In "Secret Origins, Part 3", after Honeycutt imitates Shredder's voice, he overrides the voice commands Shredder had on Stockman's mechanical body. This gave Stockman the chance to attack and temporarily incapacitate Shredder, allowing the Utroms to escape.
- "New Blood": Chaplin's robots are proving too strong for the Turtles. Stockman knows that if Chaplin's creations succeed, then Shredder won't have any need for his services. So he discretely sabotages the controls to make it look like an accident.
- "Exodus": Shredder is on the verge of killing the Turtles and Splinter, but Stockman reprogramed the systems on Shredder's ship to disable its defenses, causing it to take hits from Bishop's attempts to shoot it down. A lucky mission hit causes security to go haywire and lock Shredder out the engine room.
Never My Fault: Whenever his plans go wrong, he puts the blame on someone else. Notably Hun. This eventually reaches it's peak in “Insane in the Membrane” where when his clone body starts to fail him he somehow comes to the conclusion April was the cause of all his problems since that was the start of his path to his current predicament when ironically it was his sending his mousers after her that lead her to the turtles and in turn the defeats that followed. It never occurs to him that teaming with a very dangerous indiviual like the Shredder was not his wisest move.
No One Could Survive That!: In Season 2, Don blew him up with missiles and yet, he somehow survived that, including a several hundred meters fall on the ground.
Not Helping Your Case: While Shredder is indeed a terrible boss, at least part of why he abuses and maims Stockman so terribly is because Stockman can't keep his pride in check, keep his mouth shut and bide his time, instead of acting smug and insufferable before a madman with very little tolerance to disrespect, and even less for failure.
Omnidisciplinary Scientist: His primary field is usually robotics, evidenced by his famous Mousers, but he'll show expertise in everything from genetics to archaeology as suits the plot. However, giving his repeated blunders after joining Bishop, he should have stuck to robotics exclusively.
Out of Focus: He only appears in one episode of Season 5 besides the finale due to the focus on the Turtles’ battle with the Tengu Shredder.
Powered Armor: Occasionally wears this.
Sanity Slippage: Suffice to say, after four seasons of abuse his mind finally begins to snap and the results are not pretty.
Serial Prostheses: Thanks to the Shredder's attitude towards failure. He loses an eye, a hand, and ends up in a wheelchair before trying to take his revenge in a Mini-Mecha. When that fails, he's reduced to a head attached to a robot. It gets worse from there.
Scars Are Forever: Especially when they were from the Shredder's punishments.
Small Name, Big Ego: While a genius scientist, he greatly overestimates his chances whenever a real conflict starts.
Smug Snake: He greatly overestimates his cunning, and has a bad habbit of maintaining a smug and insufferable attitude before even the Shredder, despite the very numerous punishements and mutiliations that he inflicted on him.
The Starscream: Time and again, he betrays the Shredder, which would normally be a surefire way to punch his ticket to execution, but his intelligence makes him too valuable to kill off. That doesn't mean he has to be in one piece, however.
Spared by the Adaptation: Downplayed horribly. He doesn't die... But he really wishes he had.
Third-Person Person: He is prone to this when gloating.
Trauma Conga Line: Let's see: Every time he failed Shredder he was punished by having a body part sliced off, he has been reduced to a severed head inside a spider robot and then a brain, he has died only to be brought back to life because his intellect was too valuable to lose, after four seasons of abuse he finally gets a new human body again only to discover it's physically unstable and literally going to pieces. And he's not even allowed to rest in peace.
Unwanted Revival: Bishop has him brought Back from the Dead after the events of "Insane in the Membrane", needing him to complete the cure for the mutant outbreak. Stockman is mortified that he wasn't left to rest in peace.
Used to Be a Sweet Kid: He used to be a fairly benevolent and principled scientist too until his ego and arrogance got the better of him.
Was Once a Man: He NEVER stays human.
We Can Rebuild Him: Every time he takes a beating that would kill a normal human, the Foot simply rebuild him. When he actually does die, Bishop has him brought back.
Welcome Back, Traitor: Despite his betrayals, Shredder keeps him around because he's too useful while also trying to take steps to ensure Stockman can't turn on him in the future.
Wetware CPU: As he loses more and more of his body, Baxter begins becoming this.
Would Hit a Girl: Stockman on a few instances shows he is perfectly willing to get April killed if she gets in his way.
Yank the Dog's Chain: "Insane in the Membrane" for him. He transfers his mind into a new organic body, only for it to start rotting away. He goes insane throughout the episode, and seemingly gets a Redemption Equals Death when he saves April. But he isn't even allowed to die as Bishop brought him back.

Nano

To see other incarnations^note

Voiced by: Veronica Taylor (child), Anthony Salerno (adult)

Nano: Daddy!

A sentient nanomachine colony who escapes its creators and causes trouble. They can control, disassemble, reassemble, and assimilate devices and objects.

Alas, Poor Villain: Its supposed death when Harry tries to free it but accidently drops it into molten metal is quite saddening. Harry saw Nano as a son and mourns over it. Even The Turtles feel sad for Nano afterwards.
Anti-Villain: It either has the mindset of a child or is being controlled by outside forces; either way, it is rarely entirely responsible for its actions.
Dragon-in-Chief: His former boss and "father" Harry is an average human.
Earn Your Happy Ending: After spending his first two appearance as a villain, he finally redeems himself, becomes a hero and joins the Justice Force, essentially getting a family, something he always wanted.
Heel–Face Turn: He finally redeems himself in Membership Drive. He finally matures enough to understand that he had been behaving like a bad guy and apologizes to the Turtles for his actions during their past encounters and gets to join the Justice Force. He also gets to attend April and Casey's weeding in the Grand Finale.
I Just Want to Be Loved: It views itself as a child who wants to be loved by its "mother", the doctor who created it, and its "father", Harry the con artist.
Instant A.I.: Just Add Water!: For unexplained reason, the nano-machine colony started personifying, to its creator's chagrin.
Leitmotif: A curious, innocent techno piece that reflects the childish nature of Nano.
Not Evil, Just Misunderstood: As the other tropes point out, he's more a misguided child than a villain, and as such reforms into a superhero of the Justice Force in his third appearance.
Not Quite Dead: He's seemingly killed in his first two appearances but returns.
Obliviously Evil: Given its childish demeanor, Nano often takes actions for love and approval, often not realizing the damage it does to others.
Self-Duplication: Part of what makes Nano hard to destroy, as the nano-machines replicate too fast to make the Turtles' strikes be effective.
Tragic Villain: Sure, it caused destruction almost everywhere it went, but its supposed death scenes are rather disheartening.

Harry

Voiced by: Eric Stuart

Harry: Kid, I got a feeling you are the lucky break I've been waiting for!

A con artist who's the first person to encounter Nano. While initially scared of him, he later adopts Nano as his own son and uses him to commit crimes.

Accidental Murder: He tries to free Nano from an electromagnet, which he does, only for Nano to fall in a mass of molten metal. Subverted in "Modern Love", where Nano is revealed to have survived.
Characterization Marches On: At the end of "Nano", he genuinely cared for Nano and was devastated when he was presumably killed. In "Modern Love: The Return of Nano", he just sees Nano as a means to an end and wants nothing else to do with him.
Cradling Your Kill: An interesting version of this. Harry, after seemingly killing Nano, finds his mask and picks it up, talking to it and apologizing for what he just did.
Even Evil Has Loved Ones: He saw Nano as a son and mourns his death.
Jerk with a Heart of Gold: Played with. He initially cares only about himself, but eventually gets attached to Nano and is genuinely devastated when Nano is presumably killed. Of course, he's overjoyed and happy when Nano returns in Season 2...so he can continue committing crimes again.
Mistaken for Aliens: He mistakenly thinks the Turtles are invaders from Mars.
My God, What Have I Done?: He regrets getting Nano seemingly killed.
Nice Job Fixing It, Villain: At the end of "Nano", Nano gets immobilized by a large electromagnet. Harry tries to free him by disabling the electromagnet's power source. Which he does, only for Nano to fall in a mass of molten metal, seemingly killing his "son".
Non-Action Guy: He is a normal human, so he has to use Nano to defend himself.

Garbageman

Voiced by: Mike Pollock

Garbageman: Garbage is power.

A morbidly obese man who finds something special in garbage and wants to build an empire out of it.

Ambiguous Situation: An exact reason as to why he has to use vehicles to move around is never given. Is he an Evil Cripple or a morbidly obese man who can't move normally?
- The cancelled Nightmares Recycled episode reveals he is Hun's conjoined twin and surgically removed by a back alley surgeon, and tossed aside as garbage while Hun was kept and raised.
Animal Mecha: A Type 1 example. It's revealed in "Junklantis" that he built multiple robotic whales, which him and his mooks use to sunk ships.
Canon Foreigner: He was created for this series.
Crazy-Prepared: His truck from "Garbageman" has flamethrowers, buzzsaws, can spill oil and can drive underwater.
- Once again in "Junklantis", after his robotic whale gets destroyed, he escapes with a mini sub that he later uses to attack Mikey and Donatello.
Disposable Vagrant: He kidnaps homeless people with his truck and turns them into the subjects of his kingdom for this exact reason. Donatello even mentions that the police haven't issued any missing person reports because they either haven't noticed or simply don't care.
Evil Laugh: The very first thing he does (outside of his truck at least) is laugh maniacally.
Evil Plan: Has two:
- In "Garbageman", he wants to create his own kingdom on an island with homeless people as his subjects.
- In "Junklantis", he sinks ships and his mooks steal anything valuable from them in order to build his new underwater home.
Fat Bastard: He's obese, unpleasant and filthy.
Filler Villain: He doesn't have any connections to the major villains and isn't important to the Shredder storyline.
Island Base: His initial base of operations in "Garbageman".
Gas Mask Mooks: His followers wear gas masks.
New Era Speech: The Garbageman gives one to the homeless people he has kidnapped to make them his slaves.
The Garbageman: Before I brought you to this island, you were nothing but human garbage. No home, no purpose, no value. But now, I have recycled you, given you work sifting through the refuse that this city stupidly squanders to build my fortune. Behold the birth of my empire, invisible to the outside world until it is too late!
Screw the Rules, I Have Money!: Leo assumes that this is how the Garbageman has been able to operate unhindered. A few payoffs to the right people, and as long as he doesn't draw too much attention to himself, his island is off the radar.
Sinister Car: His truck from "Garbageman". Combines this with Red and Black and Evil All Over as it is entirely black with red headlights.
Tom the Dark Lord: In "Garbageman", the Turtles didn't took the idea of a guy called Garbageman going around and kidnapping people all that seriously. In the very next scene, the Garbageman proceeds to ransack the entire hideout of the homeless people and kidnap everybody.
Uncertain Doom: After being defeated by Donatello and Michaelangelo in "Junklantis", he sinks to the bottom of the ocean....and we never see him again. In "Garbageman", he fell in the water and survived, but here he sinks deep into an underwater ravine.
Underwater City: After his initial defeat, he creates a new home underwater. Michalangelo calls it "Junklantis".
Villain Has a Point: After the Garbageman's first defeat, the Professor says that the former's New Era Speech was correct on one thing; a lot of valuable items are thoughtlessly disposed of by the society.
Visionary Villain: In "Garbageman", he wants to force the kidnapped homeless people to build for him an empire out of the trash.

Dr. Malignus

https://static.tvtropes.org/pmwiki/pub/images/tmnt_blog012_06.png

Voiced by: David Brimmer

Dr. Malignus: Did I mention he's completely under my control?

Silver Sentry's arch-enemy, who uses his engineering prowess to commit super-crimes.

The Bus Came Back: He made just one appearance in the first season during Michelangelo's teamup episode with Silver Sentry and remains absent for the remainder of the series (aside from appearing in a story told by Michelangelo during Fast Forward) until the seventh and final season where he makes one more official appearance.
Card-Carrying Villain: As to be expected from his name, he proudly calls him an evildoer and refers to his plans as evil.
Evil Laugh: As part of his super-villain schtick, he is quite prone to laughing maniacally.
Hoist by His Own Petard: His second appearance in Back to the Sewers shows him holding the only weakness to Raph's Green Mantle cape, a yellow thimble. Raph and Mikey having accidentally ripped it in half, throw it at him, making him lose his energy. He even lampshades it saying sometimes he says too much.
Villain of Another Story: The Arch-Enemy to Silver Sentry and is implied to have battled him frequently in the past, but always managed to get away. Until Michelangelo came in.
Villain: Exit, Stage Left: Mentions that he always has an escape plan, allowing him to remain at large despite Silver Sentry foiling his plans. But he didn't count on Michelangelo getting in the way of said plan.

Black Horde

Various drawings of Kirby, who turned evil and attack the Warriors.

Art Initiates Life: All of them were originally drawn by Kirby before being given life by the crystal on Kirby's pencil.
Carry a Big Stick: One of them is seen carrying a club.
Forehead of Doom: One of them has a noticeable monstrous forehead.
Flat Character: All they want is to slaughter all of Kirby's Warriors and the residents of their city, but aside from that we know nothing about them.
The Horde: Obviously, though they aren't the minions of some Evil Overlord.
Horns of Villainy: A lot of them have horns.
Logical Weakness: They were all originally drawings of Kirby, who still has them in his sketchbook. How to defeat them? By drawing their original sketches with chains.
Would Hurt a Child/Would Hit a Girl: They want to slay everyone in the Warriors' city, including the women and children.
You All Look Familiar: The Black Horde has 4 different designs, so expect them to get reused a lot.
Zerg Rush: Their numbers are in the hundreds.

Dr. Abigail Finn

https://static.tvtropes.org/pmwiki/pub/images/dr_finn.png

^{Click to see her assistant}

Voiced by: Megan Hollingshead

Dr. Finn: There's a monster back there and I am going to hunt it!

Doctor Finn is a gifted hunter and host of the TV show "Monster Hunter". She has footage of a monster near Casey's farmhouse and won't give up until she finds it.

Anti-Villain: While Finn inspires less sympathy than the cryptid she's pursuing, she isn't trying to kill the Green Man and merely wants to prove that monsters exist (which they do, in great numbers), and finally earn the respect of her fellow scientists and the public. Her methods are also relatively humane compared to Marlin, another hunter who appears in Season 3.
Brawn Hilda: Her muscles are comparable to Casey's.
Bunny-Ears Lawyer: She's extremely hammy and a lunatic, but is extremely competent at her job.
The Cuckoo Lander Was Right: She's technically right about there being a monster in the woods, since the monster in the video is Mikey. In reality, there is a monster in the woods and the Turtles do their best to stop her from capturing it.
The Determinator: Donatello has this to say about her:
Dr. Abigail Finn doesn't give up. If she can't find what she's looking for out there, she'll come looking in here. She's obsessed with monster hunting.
Glory Seeker: She wants to get famous by hunting monsters.
Large Ham: She can't say a word without being overdramatic. Even when talking about cable show deals, she's dramatic.
Omnidisciplinary Scientist: She's a brilliant technologist and biologist.
Obliviously Evil: She is just the host a TV shows about hunting monsters. She doesn't know (to be fair, there isn't any way for her to know) that the Green Man she's searching for is a benevolent monster, who just wants to be left alone with its kids.
Show Within a Show: She's the host of "Monster Hunter".
Surveillance Drone: She uses these when she searches for the monster in the woods.

New York Mafia

Big Boss

Voiced by: David Brimmer

Big Boss: There's a gang war coming now that the Shredder is out of the picture and nothing's gonna stand in my way. Nothing!

Big Boss is a member and leader of the New York Mafia. He's an opportunistic individual who prefers to act from a position of strength, his Mafia becoming more active when the Foot Clan gets weakened.

Canon Foreigner: Him, alongside his entire organization, was created for this series.
The Don: He leads the New York Mafia.
Expy: He's very similar to The Kingpin, as they're both crime bosses who lead criminal organizations. Tho Big Boss gets more involved into the fights of his Mafia and doesn't appear overweight.
Enemy Mine: During the "City at War" three-parter, he makes it pretty clear that he despises his new ally, but due to circumstances (his organization being in a war with the Foot and the Purple Dragons, which it's losing) he's forced to work with them. His new ally turns out to be Baxter Stockman, who designed a robot that they can use in their fight against the other villains.
Evil Power Vacuum: After Shredder's apparent death in "Secret Origins", his Mafia, the Foot Clan and the Purple Dragons are all fighting for control over New York.
Evil Sounds Deep: His voice isn't as deep as the Shredder's, but it's still impressive.
Good Old Fisticuffs: In his first appearance, he fights Raphael with his bare fists. Though in his later appearances, he uses a rocket launcher.
Large and in Charge: He's the leader of the New York Mafia and can easily defeat Raphael (a blind Raphael at least) in a fight.
Villain in a White Suit: His main outfit is a white suit.
What Happened to the Mouse?: After the "City at War" three parter, he is never seen again alongside his entire organization.

Weasel

Voiced by: Michael Sinterniklaas

Weasel: Boss! We got us a problem.

A member of the New York Mafia and Big Boss' lieutenant.

Butt-Monkey: He gets kicked twice by Tyler, a little kid.
Four Eyes, Zero Soul: He wears goggles and fully intends to kill Tyler.
Only Known by Their Nickname: He's called "Weasel" and we never discover his real name.
Would Hurt a Child: He fully intends to take out Tyler.

Turtlebot

A robotic duplicate of the Turtles, who was created by Baxter Stockman.

All Your Powers Combined: A variation. The Turtlebot was programmed to know each of the Turtes' fighting styles.
Canon Immigrant: It debuted in the first video game adaptation before making its way into the show during Season 2.
Crippling Overspecialization: It was designed to perfectly mimic and counter the Turtles' usual fighting styles. Once they completely alter their fighting styles by switching weapons, however, it can't adapt to the changes and is defeated quickly.
Flat Character: This thing is a evil robotic duplicate of the Turtles and...that's about it.
Logical Weakness: The Turtlebot was programmed to know each of the Turtles' fighting styles...with their weapons of choice. When they switch their weapons around, it is easily defeated.
Mythology Gag: The Turtlebot looks like Metalhead.

Texas Roughnecks

Bobby (left), Slim (middle) and Robby (left)

Voiced by: Wayne Grayson (Bobby), Ted Lewis (Slim) and Marc Thompson (Robby)

Slim: There she is, boys. Now you all bag 'er and tag 'er.

A group of cowboy-inspired criminals who want to steal the Golden Puck for their boss, a man named Mr. Arboost.

Cowboy: They are stylized after cowboys, have southern accents and use lever-action-looking laser-rifles.
Identical Twins: Robby and Bobby are basically indistinguishable without their respective green and blue shirts.
Oral Fixation: In "The Golden Puck", Slim chews a match during most of the episode. Thanks to this, the Turtles and Casey are able to find his matchbox and track him to the hotel him and the others are staying.
Revenge: Their boss, a man named Mr. Arboost, ordered them to steal the Golden Puck, because the authorities wouldn't let him have a Super Slam Hockey Team.

Mr. Touch and Mr. Go

Mr. Touch(right) and Mr. Go(left)

Voiced by: Marc Thompson(Touch) and Pete Zarustica(Go)

Mr. Touch: Am I late, Mr. Go?

Mr. Go: Fashionably, Mr. Touch.

A duo of assassins who are hired by Hun in order to take out the Turtles.

Adaptational Backstory Change: In Mutant Nightmare, the third video game adaptation of the series, Touch and Go work for Bishop instead of Hun.
Big Guy, Little Guy: Mr. Go is an average sized man. Mr. Touch is a huge guy, to the point that he is possibly the only human character in the show who can directly look Hun (who is 7'2") in the eye without having to look upwards.
Canon Foreigner: The pair were created solely for the 2003 show and have not appeared in any other incarnation either before or after the series.
Hired Guns: They are hired by Hun in order to eliminate the Turtles.
Punch-Clock Villain: They don't really hate the Turtles, as they just hunt them down for the money.
Villain in a White Suit: Mr. Go wears one of these.
Wonder Twin Powers: Their powers are only activated when they bump their fists.
What Happened to the Mouse?: They reappear in "Nobody's Fool" as some of Hun's henchmen, but after that they're never seen again.

Marlin

Voiced by: Marc Thompson

Marlin: Ladies, let the hunt begin!

Marlin is an egocentric hunter, whose obsession with hunting the most exotic, dangerous game results in him hunting down Leatherhead.

Cloudcuckoolander: He's a bit too attached to his weapon and robot companion.
The Determinator: He would do anything in order to hunt his game.
Dies Differently in Adaptation: In the original comics, he was killed by another hunter. Here, he's dealt with by Leatherhead.^note
Egomaniac Hunter: He hunts the most exotic, dangerous game he can find, which results in him hunting Leatherhead.
Evil Poacher: He's hunting Leatherhead in New York.
Expy: He's similar to Kraven the Hunter as they both have an obsession with finding and hunting the next big game. Unlike Kraven though, Marlin doesn't have any problems with using guns during his hunts.
The Greatest Story Never Told: Invoked when he says this:
It's a shame, really. No one will know that with my last breath, I hunted down five of the most amazing animals I've ever seen.
I Call It "Vera": He calls his gun "Betsy".
Laser Hallway: He sets up one in the sewers during his hunt for Leatherhead.
Robot Buddy: He has a robot companion he calls "Amelia".

Skonk

Voiced by: Sean Schemmel

Skonk: They are dug deep in the Big Apple and nobody is doing a freaking thing about it, until now!

The radical leader of a terrorist organization, whose motivation is to eliminate any aliens that roam the planet.

Beware the Silly Ones: Raphael initially dismisses Skonk and the rest of H.A.T.E. as a bunch of wackos, but Donatello warns him that they still got some dangerous tech at their disposal. He's immediately proven right.
Conspiracy Theorist: His organization and him believe that there are aliens who have remained on Earth after the Triceraton invasion.
Fantastic Racism: Him and his organization absolutely hate aliens and want to rid the world from them.
Fun with Acronyms: His organization is called "Humans Against the Extraterrestrials", a.k.a H.A.T.E.
Insane Troll Logic: Skonk says the supposed alien sightings have all taken place in New York City, so the only solution is to blow up the city with a nuke.
Mistaken for Aliens: During his encounters with the Turtles, he initially assumes they are aliens, who want to foil his plans.
Not-So-Well-Intentioned Extremist: He proclaims himself a defender of humanity, but has no qualms killing other humans to carry out his scheme of alien genocide.
Race Lift: In the original comics, Skonk was black. Here, he's white.
Spared by the Adaptation: In the original comics, he was killed by the bomb he detonated. Here, he is left to the authorities.
Western Terrorist: He wants to blow up New York City with a nuke, because he believes that the city is inhabited by aliens.

Ruffington

Voiced by: Marc Diraison

Ruffington: Some costumed vigilante has been nosing around my plant. I've had to take precautions.

A corrupt supplier and smuggler of high-tech weapons, whose biggest clients seem to be the Purple Dragons.

Arms Dealer: After the Triceraton invasion, there are a lot of high-tech weapons around the Earth, and he's the one who's selling them.
Corrupt Corporate Executive: In a flashback from "Nobody's Fool", he is said to be a weapons supplier for the government. In the meantime, he also supplies weapons to gangs and other illegal clients.
Create Your Own Hero: At one point, a New York detective discovered his corrupt ways and was about to expose him. Due to this, Ruffington used his power and influence to ruin said detective's career forever. The said detective consequently turned to vigilantism in order to stop Ruffington and became the superhero known as Nobody.
Fantastically Indifferent: In "Nobody's Fool", what is his reactions to seeing two mutated turtles and a costumed vigilante? Mild annoyance. Possibly justified, since the weapons he is selling are of alien origin and that several episodes earlier the Triceraton invasion took place.
Ruffington: What's with the costumed freaks around here? Take them out.
Four Eyes, Zero Soul: He's a corrupt weapons supplier, who wears glasses.
Non-Action Big Bad: He's just an ordinary human, so he has to use mooks to protect himself and his weapons.
Screw the Rules, I Have Connections!: After Nobody discovered his corrupt ways, he used his power and influence to ruin his career.
Spared by the Adaptation: Ruffington was killed in the comic that "Nobody's Fool" is based on.
Who Are You?: Happens two times: when he first meets Nobody and when he gets captured by him.
Ruffington: Who are you?
Nobody: Thanks to the politicians in your pocket, I'm nobody.
Ruffington: Then you won't be missed.
—-
Ruffington: Tell me who you are! I have to know!
Nobody: [beat] Somebody.
What Happened to the Mouse?: After his brief appearance in the "Enter the Dragons" two-parter^note, we never see him again.

Necro Creature

https://static.tvtropes.org/pmwiki/pub/images/necro_monster.png

Voiced by: Sean Schemmel

Necro Creature: Feel my power, see my strength! You cannot fight me, you cannot win!

An extra-terrestrial entity that landed on Earth hundreds of years ago. Now, it attracts anyone to its presence and corrupts them by using their fears and inner greed.

Animalistic Abomination: It has the body of a scorpion and the head of an octopus. Not to mention its mouths, wings on its back and many, many tentacles.
Badass Boast: As the creatures emerges from the ground, it says one of these. ^noteThe boast is actually quoted above
Been There, Shaped History: It's implied that the creature is responsible for why Europeans came to America, which means that without it, the modern-day world wouldn't exist.
Came from the Sky: The creature landed on Earth hundreds of years ago in North America with an asteroid.
Canon Foreigner: This creature was created for this series.
Combat Tentacles: Throughout most of the episode it appears in, we can only see its tentacles. At the end, when it reveals itself, it's discovered that the tentacles are coming out of its face.
The Corrupter: Its defining power. This creature can telepathically communicate with anyone it wants to, no matter the distance ^note, and can promise them anything they desire. It uses their fears and greed against them, in order to achieve its goals. And even when they try to resist and stop the creature, its grasp over them is too strong for them to battle.
Eldritch Abomination: Certainly. This creature came from space, corrupts people and tortures them by making them live their worst nightmares for who knows how long and for who knows what reason. This creature has manipulated humanity for at least several hundreds of years, is a giant mass of Body Horror and from what we know is immortal.
Expy: The creature is an obvious homage to the various eldritch abominations that were created by H. P. Lovecraft, though it's most similar to Cthulhu and Nyarlathotep:
- The creature is visually similar to Cthulhu, since both of them are massive, have octopus-like heads and have wings,^note though they differ, as Cthulhu is more humanoid, while the creature is more scorpion-like.
- The creature also bears some similarities with Nyarlathotep, as they both usually speak in human languages and manipulate humanity in order to achieve their goals (both of which are also unknown).
Evil Is Bigger: When the creature reveals itself at the end, it completely dwarves Leo (the scene is pictured above).
Evil Sounds Deep: Whenever it speaks, it has a deep voice.
Hellgate: What separates the creature's chamber and outside world is a gate. Its chamber is filled with dead humans who have been previously tortured for the rest of their lives. Hell, above the gate is written "Abandon all hope, ye who enter here" in Latin.
Greed: How it attracts new victims to its presence. If the creature doesn't devour them, then it will promise them immense wealth if they follow its orders and fall under its influence. The victims, even if they try to resist it, wouldn't be able to fight back since by this point they would have been under its influence for too long.
Mind Rape: When it puts its victims through their worst nightmares, it also tortures and mindrapes them. Nice!
Mix-and-Match Critters: It looks like a cross between an octopus and a scorpion, but with dragon wings.
Nightmare Weaver: After the creature captures its victims, it puts them in organic pods, where it makes them live their worst nightmares. And from the fact that the Turtles discover that in the other pods, there are skeletons, it's likely the creature makes its victims live their worst nightmares for the rest of their lives.
No Name Given: The creature's name is never revealed. We don't even know if it has one.
Not Quite Dead: After the Turtles assume the creature has been defeated and leave, it's revealed that it has survived and continues to attract new victims to its presence.
Red and Black and Evil All Over: If the chamber that the creature inhabits isn't entirely dark, then it is illuminated by its light, making the entire chamber entirely red with very sharp shadows.
Red Eyes, Take Warning: This creature and everyone that's under its grasp has red eyes.
Vagina Dentata: Its mouth resembles...well, you know.
What Happened to the Mouse?: The end of "The Darkness Within" certainly indicates that the creature has survived and that it might return, but it doesn't.

The Slayer / The Rat King

The Slayer/ Rat King

https://static.tvtropes.org/pmwiki/pub/images/slayer.jpg

To see his Rat King persona^note

Voiced by: David Zen Mansley

Bishop when describing the Slayer: A handsome devil, if I do say so myself.

A man dressed up in rags and bandages who shares a rapport with rats.

Aborted Arc: His episode ending, which clearly indicated he was going to return, but it never happened. Closest he ever came to returning was watching April and Casey's wedding in the final episode.
Adaptational Badass: In his first comic appearance, he didn't have any major fighting skills; he relied on vantage points. This version is the Slayer from last season—a Super Soldier that can take on all five heroes at once and survive all kinds of punishment.
Adaptational Late Appearance: His first appearance, "Bishop's Gambit", doesn't occur until Season 3, late in the series, and doesn't don the Rat King identity until "I, Monster", a Season 4 episode. Due to this, he doesn't play any role in the "City at War" arc (where he appeared posthumously in the Mirage comics), which was in Season 2.
Adaptational Villainy: In his first comic appearance, the Rat King only menaced the Turtles and Casey because he sincerely believed they were other monsters trying to take his territory from him. Also, he only fed dead or dying animals to his rats before the heroes came along, whereas this episode implies he's been feeding them humans for some time.
Ambiguously Brown: Like his genetic template Bishop, he has tan skin which could either reference genetic heritage or just time outdoors.
Back for the Finale: After a long absence through the series, he makes a small cameo watching April and Casey's wedding.
Bandaged Face: In his second appearance, he's covered in bandages.
Canon Character All Along: The Slayer that he originally was appears to just be another one of Bishop's one-off experiments, but ends up becoming the Rat King.
Comic-Book Movies Don't Use Codenames: He is never referred to as "Rat King".
Exorcist Head: As the Slayer, he can twist his head around.
Mind Control: Subverted. It is never said how he controls rats, but presumably it is related to his being formed from mutated rat (Splinter's) DNA.
Mix-and-Match Man: He is one of these, using DNA from Bishop, Splinter, among other possible sources.
Spared by the Adaptation: He was Killed Off for Real in the Mirage Comics, which the show is more closely based on, but lives in this version.
Suddenly Voiced: In "I, Monster", he is somehow able to speak.
Super-Soldier: His Slayer persona was designed to be one. He is a prototype bio-mechanical super soldier created by Agent Bishop using genetically manipulated, alien, the Turtles', his own and Splinter's DNA.

Moriah

Voiced by: Megan Hollingshead

Moriah: Poor Jhanna! Someone like you would never understand politics.

An alien woman who's the tyrannical ruler of her people. She was challenged by Jhanna to fight in a duel, the winner of which will become the new ruler of her people.

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 Moriah makes her debut in Season 4.
Adaptation Species Change: Sort of. In the original comics, she was a part of a human-looking alien race, while in this series, she's a part of a more alien-looking race, having blue skin and all.
Bare Midriffs Are Feminine: In her battle against Jhanna, she wears an outfit that shows her midriff.
Combat Pragmatist: She would do anything in order to win against Jhanna, like bringing her servants^note to the battle or throwing dust in Jhanna's eyes.
Challenging the Chief: In this case, she's the chief. Jhanna challenged her for a duel, the winner of which will become the new ruler of her people.
Combat Stilettos: She fights Jhanna in high heels.
Dark Action Girl: She can handle Jhanna quite well in a battle, but also relies on her servants.
Evil Redhead: She's the tyrannical ruler of her people, who has red hair.
Facial Markings: She has purple markings on her face.
Green-Skinned Space Babe: Much like Jhanna, she's an attractive blue alien woman, who fights Jhanna in her official attire, that shows her midriff and quite some skin.
Kicking Ass in All Her Finery: She battles Jhanna in quite an intricate outfit.
Near-Villain Victory: Her minions were nearly victorious in killing Jhanna, until the Turtles assisted and helped her.

Elemental Motifs: With the exception of the serpent, each represents an element: earth (the Rock Monster), water (the liquid creature), and air (the pterosaur).
Feed It a Bomb: The rock creature and the water one are tricked into devouring bombs that blow them apart.
Half the Man He Used to Be: Leonardo cuts the serpent in half, but the half with its tail just grows a head, while the half with the head grows a tail, leaving the Turtles with two serpents to fight.
Kill It with Water: The serpent reacts to water as if it's acid and is reduced to a pile of sludge after being engulfed by a wave.
Sole Survivor: The pterosaur is seemingly the only one to survive the episode.
Throw Down the Bomblet: The Rock Monster has a belt of grenades and is happy to use them. It's blown into pieces after one of those grenades is hurled into its mouth.
The Voiceless: None of them have any dialogue, just shrieks, burps, and growls.
What Measure Is a Non-Human?: They're grotesque-looking (by human standards) and the three with the most inhuman features suffer onscreen deaths (unless Bizarre Alien Biology somehow lets them regenerate), while the more humanoid looking flier is only knocked out.

The King of Thieves and his accomplices

The King of Thieves

https://static.tvtropes.org/pmwiki/pub/images/king_of_thieves.png

The King of Thieves

Hadji

Voiced by: Sean Schemmel (King of Thieves)

Hadji: Will we use that money to buy the item?

King: Of course not, my dim companion. It must be stolen, for am I not the King of Thieves?

A professional criminal out to steal the statue of a thievery god and bring the creatures within it to life. He is accompanied by a dim-witted sidekick named Hadji and also hires several costumed local criminals to steal the statue from April's shop.

Adaptational Nice Guy: He's a nasty piece of work, but his comic counterpart brainwashes homeless people to steal the statue and then murders them. In the show, he simply sends other thieves to steal the statue and sends them on their way afterward.
Batter Up!: Two of the men he sends to rob April's shop use a baseball bat against Michelangelo.
Dark Is Evil: The King of Thieves is a greedy brunette megalomaniac who wears a dark coat and hat.
Evil Brit: The King of Thieves is a ruthless schemer with a British accent.
Evil Sorcerer: After he obtains the statue, he proceeds to summon multiple thieving monsters and demons, who he sets out to steal for him.
Fatal Flaw: Two, Pride and Greed. The man revels in his (presumably self-appointed) title and orders the monsters he's summoned to keep stealing more and more. He refuses to spend money on anything that he can steal instead (even when hiring thieves to assist him probably costs more), which draws the Turtles' attention when he steals April's statue.
Multi-Armed and Dangerous: The thievery god he brings to life has six hulking arms capable of inflicting a lot of damage in a fight.
No Ontological Inertia: After the thievery god is defeated by the Turtles and turns to dust, so does every monster and demon that spawned from it
Percussive Pickpocket: He bumps into a man on the street and lifts his wallet.
Small Name, Big Ego: Despite his title, the King of Thieves pays other thieves to do anything riskier than pickpocketing for him.
The Watson: Hadji serves as someone for the King of Thieves to brag about his plans to.

Jencko and the Turks

Jencko

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2021_11_03_133313.png

Voiced by: Sean Schemmel

A ruthless and mean-spirited thug, who's the leader of a gang called the "Turks"

Bad Boss: Believing that a member of his gang is ratting them out, he decides to beat him up.
Canon Foreigner: Was created for the series.
Pipe Pain: Uses a pipe to beat a member of his own gang who he believes is ratting them out.
Token Evil Teammate: Jencko is this in his own gang. Nobody knows some of the other members through his police work and believes they're not all bad, but he tells the Turtles that Jencko definitely is.
Would Harm a Senior: After an old man sees him beating up a member of his own gang, Jencko proceeds to chase him and if it weren't for the police, he most likely would have been beaten to a pulp.

The Turks

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2021_11_03_141504.png

The gang led by Jencko

Heel–Face Turn: After Nobody gave them a speech, all of them bar Jencko give up and disband.
The Mole: X-ray acted as an informant to Nobody.

The Brotherhood

https://static.tvtropes.org/pmwiki/pub/images/brotherhood_2.png

An alien race of reptiles, who claim to want to bring peace and prosperity to Earth.

Asshole Victim: At the end of "Trouble with Augie", the Brotherhood soldiers and their leader get killed by the giant hornets from "April's Artifact". Though they certainly deserved it.
Bitch in Sheep's Clothing: They initially present themselves as a peaceful race, who want to bring prosperity to Earth. In reality, they travel through dimensions and feed on everything they encounter. They also plan on eating humanity when Augie fixes their teleporter.
Clark's Third Law: They initially invoke this trope, calling Augie a "magician" and all. Subverted, as they do know what Augie is and in fact are manipulating him to fix the teleporter.
Dirty Coward: At the end of "Trouble with Augie", their leader tries to run away from the giant hornets, leaving the rest of his men to die.
Karmic Death: They travel to different dimensions and eat everything they encounter. At the end of the episode, they get eaten by the giant hornets from "April's Artifact".
Killed Off for Real: The Brotherhood leader and his soldiers get killed by the giant hornets from "April's Artifact".
Lizard Folk: They are all giant bipedal lizards.
Manipulative Bastard: Their leader is manipulating April's uncle Augie, claiming his race only wants peace and prosperity. And he believes them. They manipulate him, as they want him to fix the broken teleporter, so they can continue on eating whatever they encounter.
Reptiles Are Abhorrent: They resemble reptiles and want to conquer Earth and eat humanity.
To Serve Man: Their motivation. They travel to different dimensions, conquering them and eating the inhabitants. It even gets lampshaded:
Uncle Augie: The Brotherhood wish to serve humanity!
Donatello: Yeah. Medium rare. Like that Twilight Zone episode!

Family and Relatives

Augustus O'Neil

Voiced by: Marc Thompson

Augie: I leave behind this journal and my compass pendant, should any other poor soul end up in this infernal place.

Augustus was April's uncle, who some time ago mysteriously disappeared.

Apocalyptic Log: In "April's Artifact", during his time in the alternate dimension, he documented his days while traversing the dimension and searching for a way back home.
Badass Bookworm: During his time in the alternate dimension, he has been mathematically analyzing the cube that teleported him there in order to find how it works and to find a way back home. There, he also survived getting attacked by giant hornets for at least several years.
Cool Uncle: He is April's uncle, who would regularly be missing for several months and return with various trinkets. Now, he's lost in alternate dimensions, has survived giant insects and is searching for a way back home.
The Homeward Journey: His subplot revolves around him returning to Earth.
In-Universe Nickname: April calls him Uncle Augie.
Long-Lost Relative: At the beginning of "April's Artifact", April mentions that he often went on journeys for months, but one day he never came back. In reality, he has been transported to an alternate dimension.
Mistaken for Aliens: In "Trouble with Augie", he meets Donatello and initially thinks he's a being from another dimension.
Trapped in Another World: Before he disappeared, he found a mysterious cube that, after activating it, transported him in an alternate dimension.
Unwitting Pawn: In "Trouble with Augie", he's being manipulated by the Brotherhood in order to fix the teleporter, so they can come to Earth and eat humanity.
Wide-Eyed Idealist: In "Trouble with Augie", he truly believes that the Brotherhood will bring prosperity and peace to Earth. Of course, it's discovered that he's being manipulated by them and soon tries to sabotage their plans.

Mrs. Jones

https://static.tvtropes.org/pmwiki/pub/images/caseys_mom.png

Voiced by: Kayzie Rogers

Mrs. Jones: Who's this crazy woman, Arnold?

Casey: Ma, I told you never to call me that.

Casey's mother.

Back for the Finale: She returns in "Wedding Bells and Bytes", where she attends April and Casey's wedding.
Secret Test of Character: Upon first meeting April, she subjects her to an increasingly aggravating series of chores, all while being rude and bossy to her. When an exasperated April finally completes the tasks, Mrs. Jones becomes much nicer, even inviting April to call her "Mom", implying that she wanted to see if April's devotion to Casey was strong enough that she'd be willing to go through anything for him.
Secret-Keeper: The end of "H.A.T.E." implies that during April's tests, she saw Leo and Splinter helping her and asks Casey to tell her about them someday. She seems to not have told anyone about them with the exception of Sid.
So Proud of You: She is most impressed with how April handled her tests.
Unnamed Parent: Her name is never revealed.

Arnold Jones, Sr.

Voiced by: Brian Maillard

Casey: Please, Pops, don't go.

Arnold Jones, Sr.: I gotta, kiddo. I put everything we had into that store. I can't just let them get away with this. I'm going to the police.

Casey: But they said no cops! They said if you—

Arnold Jones, Sr.: Casey, sometimes you just gotta stand up for what's right, even if the odds are against you. Even if you're all alone. You gotta just stand up and do the right thing.

Casey's father.

Death by Origin Story: It is heavily implied that Hun is personally responsible for his death. And this is why Casey holds a grudge against Hun.
Deceased Parents Are the Best: He appears via flashbacks in only one episodes and is established as a law abiding Nice Guy. He is also long dead by the time the events of the first episode take place.
Depending on the Writer: In the short-lived Dreamwave comics by Peter David, which adapted the early episodes of this show, he was portrayed as an abusive father. In the show itself, Arnold Sr. is a loving father and husband who taught Casey to always do the right thing. Turtles Forever establishes that the Dreamwave comics is an Alternate Universe in the multiverse, so they are two different versions.
Strong Family Resemblance: He looks a lot like his son, only with shorter hair, bigger sideburns and a slightly average physique, as opposed to Casey's bodybuilder-like appearance.

Sid Jones

Voiced by: Johnathan Todd Ross

Sid: Last time I checked, this was my grandma's house, too.

Casey's cousin, who's in debt with the Purple Dragons.

Adaptational Heroism: In "Cousin Sid", he's a desperate man, who's searching for his grandfather's treasure, but in the comic the episode is based on, he was the ringleader for a gang of thugs in his quest to find the treasure. Here, he's just a guy who owes a lot of money to the Purple Dragons, who show up at the farm to check on his progress. The episode also ends with Sid on fairly good terms with Casey, whereas he was a real mess in the comic.
Back for the Finale: After not appearing since "Cousin Sid", he attends April and Casey's wedding in "Wedding Bells and Bytes".
Consummate Liar: As well as a Bad Liar. Is implied by Casey to have lied multiple times in the past, but Casey doesn't get fooled by him in the present.
It's All About Me: Casey accuses Sid of this and he isn't wrong.
Not-So-Badass Longcoat: He wears a trenchcoat, but he isn't badass at all. In fact, he's quite desperate and pathetic.
- Subverted in "Wedding Bells and Bytes", where he battles the Cyberfoot alongside the other characters, but by that point he's wearing a nice suit.
Perma-Stubble: He seems to not have shaved for a long time.
Secret-Keeper: In "Wedding Bells and Bytes", Mrs Jones says that she told him about the Turtles and Splinter on the condition that he will not tell anybody, otherwise she'll "bust his kneecaps."
Took a Level in Badass: In "Cousin Sid", he's a desperate man, who's been searching for his grandfather's treasure for a long time. In "Wedding Bells and Bytes", he battles the Cyberfoot alongside everyone else.
Trenchcoat Warfare: In "Cousin Sid", he is forced by Casey to leave their old farmhouse. He refuses and pulls out a Federation blaster.
Unseen No More: He was mentioned by Casey way back in "Tales of Leo" from Season 1, but he wouldn't appear until "Cousin Sid" from Season 4.

The Federation

As a whole

https://static.tvtropes.org/pmwiki/pub/images/the_fed.png

A militaristic civilization that aspires to conquer the galaxy. It is one of the dominating forces in the galaxy, the other being their enemies — the Triceratons.

Adaptational Late Appearance: In the original comics, the Federation appeared as early as issue 5 of the first volume, in what was essentially a crossover.^note In this series, most of the stories that happened after their introduction had already been adapted in Season 1, while the Federation make their debut in Season 2.
Evil Versus Evil: The Federation is in a constant conflict with the Triceratons.
Human Aliens: They are practically indistinguishable from humans, which is pretty noticeable when General Blanque stands next to Agent Bishop.
Leitmotif: A militaristic tune that resembles an army hymn.
People's Republic of Tyranny: They are a militaristic force that wants to conquer the galaxy, which calls itself the Federation.
Periphery Demographic: In-Universe. Blanque mentions that "Triceraton Gladiators", a.k.a. "The Games", are very popular on D'Hoonib.
Standard Human Spaceship: Overlaps with Evil Is Angular. Their spaceships are fairly rectangular, which can be seen when Fugitoid infects the whole Federation fleet with a virus as we get to see the entire fleet.
Villain Team-Up: In "Worlds Collide", they work with Bishop and his Earth Protection Force. The Federation offers them alien technologies if they recover the Fugitoid, who's on Earth.

General Blanque

https://static.tvtropes.org/pmwiki/pub/images/blanque.png

Voiced by: Pete Zarustica

Blanque: The teleportal must be ours! The Fugitoid must be captured!

The Head of the Federation's Armed Forces. General Blanque is a ruthless warmonger who will do anything to achieve victory over his enemies.

Adaptational Karma: In the original Mirage comics, he goes unpunished for persecuting the Fugitoid and trying to force him to create a Weaponized Teleportation device against his will. In this series, however, he gets his comeuppance when he comes to Earth to capture the Fugitoid and forcibly extract the blueprints for the teleportal from his head. The Fugitoid tricks Blanque into uploading a virus that disables the entire Federation fleet while the Turtles and their allies subsequently defeat Blanque and his men; Blanque is last seen in a Triceraton prison with Zanramon.
Big Bad Ensemble: General Blanque and Zanramon are this for the "Triceraton-Federation War" arc.
Evil Redhead: Has orange hair and is a corrupt warmonger.
Galactic Conquerer: He wants to rule the galaxy under the banner of the Federation.
General Ripper: He's the head of the Federation's military, a ruthless warmonger and is consumed by the idea of ruling the galaxy under the Federation.
Hoist by Their Own Petard: Blanque is defeated in "Worlds Collide, Part 3" after Honeycutt turns his own tech against him. After all, Honeycutt is responsible for designing most of the Federation's technology.
Internal Reveal: In "Turtles in Space, Part 5", Mozar reveals that Lonae is a spy for the Triceratons. He's obviously surprised, but the audience knew that since Part 1.
Non-Action Big Bad: He largely orders his men to do the dirty work.
Weaponized Teleportation: The reason why both him and Zanramon want the Fugitoid, as he has created a teleportal that can be used to transport weapons of mass destructions directly into their enemies, essentially allowing them to conquer the galaxy with ease.

Lonae

Blanque's personal aide.

Bowdlerise: In the original comics, she was a drug addict that wanted more of the Triceraton's drugs, which served as her motivation as to why she was giving them intel. Here, she wants to get more rich.
Greed: Her sole motivation as to why she's a double agent for the Triceratons. In "The Trouble with Triceratons", she demands more in exchange for the intel. Even Mozar is disgusted.
The Mole: Is this for the Triceratons, as she provides Mozar with intel on the Fugitoid's whereabouts, eventually leading to his capture.
Rewarded as a Traitor Deserves: She gets what she deserves when Mozar reveals her betrayal to General Blanque, who has her arrested and presumably executed for it.
Small Role, Big Impact: Lonae appears in only 4 episodes total. However, she's the one who gives the Triceratons intel on the Fugitoid, which escalates the Triceraton-Federation conflict into a full-blown war. This war eventually reaches Earth and effects all following seasons. With other words, she's responsible for the events of rest of the show.
The Smurfette Principle: She's the only female character we see that serves in the Federation.
Uncertain Doom: In the original comics, she uses drugs and overdoses. Here, she lives up until "Triceraton Wars", where Mozar reveals to Blanque that she is a double-agent for him. Blanque, obviously furious, orders her to be "seized". Lonae is presumably killed as we never see her again and is even replaced by another assistant in a following scene.
The Watson: In "The Fugitoid", she asks Blanque on why he wants the Fugitoid so badly. He proceeds to explain his entire plan to her.

The Triceratons

As a whole

A alien race of warriors that's under the dictatorial rule of Zanramon. They are in constant conflict with the Federation for control and dominion over the galaxy.

Badass Army: The teaser for "Space Invaders, Part 1" shows them in a fight against the Federation's army and winning.
Batman Can Breathe in Space: Averted, as they need proper gear to survive in space.
Easily Thwarted Alien Invasion: Played with and subverted. The only way the Turtles can stop the invasion is to convince Zanramon that the Fugitoid isn't on Earth...which they do. But as they are about to leave, the Fugitoid actually shows up. This not only brings them back, but also brings the Federation to Earth, leading to massive battles above the planet.
- Though the invasion is eventually stopped, it has effects on the entire season as humans now know that aliens exist, there's advanced alien technology in demand and Bishop makes himself prominent. Shredder also uses the alien tech to his advantage, wanting to return to the stars and have his revenge upon the Utroms.
Evil Is Angular: Interestingly, they seem to have a triangle motif: the Arena from the eponymous episode is triangle-shaped, the Triceraton Republic's logo is a black triangle with red lines, while their technology from their blasters to the space fighters are covered with triangles.
Evil Versus Evil: They have been in a war with the Federation for who knows how long.
Gladiator Games: "The Games" from "The Arena".
Humanoid Aliens: They are humanoid space dinosaurs.
Imperial Stormtrooper Marksmanship Academy: Their laser accuracy is astoundingly bad.
Mind Rape: The Triceraton mind probe. A helmet that, when put on, scans the wearer's brain and practically tortures them. It was used on Donnie, who needed mental help from Splinter in order to resist it.
Ninja Pirate Zombie Robot: They are space dinosaurs. Some of them are also cyborgs!
People's Republic of Tyranny: They are called the "Triceraton Republic" and are under the dictatorial rule of Zanramon.
Proud Warrior Race: One of their main characteristics. They are very capable fighters and have created "The Games" for entertainment.
Villain Respect: While the Triceratons as a whole aren't that villainous (with the exception of their leaders), they come to respect the Turtles after "The Arena". The two announcers also come to feel this way towards them, noting how they fight like Triceratons.

Zanramon

Voiced by: Stuart Zagnit

Zanramon: Build me the teleportal device or your friends will perish!

The tyrannical ruler of the Triceraton Republic.

0% Approval Rating: He is hated by pretty much everyone. General Blanque hates him, which is to be expected, though. Traximus despises him for sinking the Triceratons to such a low level, fighting without honor and respect. Even Mozar begins to resent him by "Worlds Collide" for his Bad Boss behavior.
Adaptation Dye-Job: In other incarnations, he generally looks like any other Triceraton. In this series, however, he's red.
Adaptational Villainy: Probably the most evil incarnation of the character. While he's quite similar to his original comics counterpart, what sets him apart is him being a massive jerkass and his willingness to kill his defenseless enemies in the "Worlds Collide" three-parter.
Arc Villain: Shares this role with General Blanque for the "Triceraton-Federation War" arc.
Bad Boss: To Mozar. Zanramon mistreats him more and more, eventually leading to Mozar refusing to protect him from Traximus and his rebellion.
Berserk Button: When things don't go his way, he's prone to getting angry and destroying anything that's around him.
Big Bad Ensemble: Zanramon and General Blanque are this for the "Triceraton-Federation War" arc.
Blatant Lies: He claims that he'll use the Fugitoid's teleportal device "for peace".
Combat Pragmatist: He is not a fighter, but he would do anything in order to win the war against the Federation.
The Coup: He is overthrown by Traximus and his rebels in "Worlds Collide" part three.
Dirty Coward: When the situation gets messy, he orders his men to protect him.
Establishing Character Moment: His very first scene, in which he meets the Fugitoid. At first he's respectful and friendly towards the professor, until he refuses to build the teleportation device. Then, Zanramon snaps and begins to threaten to kill the Fugitoid if he doesn't build it, before collecting himself and reassuring the professor that he'll use the device "for peace".
Faux Affably Evil: He initially acts friendly and respectful towards the Fugitoid when they first meet, though he quickly drops the façade and shows his true self.
Hate Sink: Zanramon is a Bad Boss, who's a coward and only thinks about himself. He would cause the deaths of innocent people and defenseless enemies if it means victory and is an all around jerkass.
Hypocrite: He claims that Triceratons fight with "honor and nobility", something he completely doesn't do.
It's All About Me: He has a massive ego and would do anything to protect himself.
Insignificant Little Blue Planet: This is how he refers to Earth in the teaser of "Space Invaders, Part 1".
Jerkass: A huge one at that. He mistreats his minions, especially Mozar, with their failure to capture the Fugitoid, which comes to bite him later.
The Napoleon: He is much shorter than the other Triceratons.
Non-Action Big Bad: He leaves the military matters to Mozar and is quite weak for a Triceraton.
Non-Standard Character Design: Unlike the other Tricerations, who have a bigger build, Zanramon has a much shorter build from them.
Oh, Crap!: His reaction when Blanque reveals that he has the Fugitoid.
President Evil: He's the prime leader of the Triceraton Republic, who doesn't hesitate at sacrificing his own men if it means to protect himself and wages a ruthless war for a device, that would be more devastating than the war itself.
Sadistic Choice: He forces the Fugitoid to build the teleportal or the Turtles will be executed.
Spared by the Adaptation: In the original comics, he's taken hostage by the Turtles and gets accidentally shot by his own men when they tried to free him. In "Triceraton Wars", this scene is adapted, but he survives. However, volume 4 of the Mirage comics revealed that he survived his injuries and his current fate remains unknown, but that issue came out in 2006, several years after the episode was released.
Weaponized Teleportation: The reason why both him and Blanque want the Fugitoid, as he has created a teleportal that can be used to transport weapons of mass destructions directly into their enemies, essentially allowing them to conquer the galaxy with ease.

Commander Mozar

https://static.tvtropes.org/pmwiki/pub/images/mozar.png

Voiced by: Dan Green

Mozar: Greetings, Professor Honeycut. We have been looking for you for some time.

The commanding officer of the Triceraton Armed Forces. His primary objective is to capture the Fugitoid and bring him to the Republic.

Adaptational Heroism: While he isn't a nice guy by any means, compared to his incarnations from the original comics and 2012 series, he's the most heroic incarnation of the character to date. In this series, he has an Even Evil Has Standards mentality and even does a Heel–Face Turn at the end of the "Worlds Collide" three-parter.
Ascended Extra: In the original comics, Mozar's purpose in the storyline is to capture the Fugitoid...and that's about it. He was a minor Triceraton commander, who in fact looked like any other generic Triceraton soldier. In this series, he's given an expanded role. He still hunts down the Fugitoid, but is also leading the Triceraton Armed Forces and is given an Even Evil Has Standards mentality. Also, Zanramon keeps mistreating him more and more, eventually leading to him doing a Heel–Face Turn and allowing Traximus to overthrow Zanramon.
Artificial Limbs: His left arm is mechanical.
Badass Boast: While escaping from D'Hoonib with the Fugitoid, he has this to say:
The Federation shall fall! We will hatch our brood in the ruins of their cities!
Determinator: He would do anything in order to capture the Fugitoid.
Even Evil Has Standards:
- In "The Trouble with Triceratons", he's genuinely disgusted at Lonae's greed.
- In "Worlds Collide, Part 3", the Federation's fleet has been infected with a virus and is essentially defenseless. He refuses to attack them due to honor. He also lets the rebellion capture Zanramon and remove him from power.
Eyepatch of Power: Wears an eyepatch over his left eye.
The Heavy: He's personally hunting the Fugitoid down in both Seasons 2 and 3.
Heel–Face Turn: He orders his men to drop their weapons and allows Zanramon to get overthrown, bringing an end to Zanramon's regime.
Hidden Depths: Downplayed, but in "Worlds Collide", he hesitates at first to abandon a group of his men, showing that he does care about his soldiers.
Honor Before Reason: He refuses to attack the Federation's fleet, because they are defenseless.
Mistreatment-Induced Betrayal: Due to his repeated failure to capture the Fugitoid, Zanramon mistreats Mozar more and more, which eventually leads to him refusing to protect the Prime minister and allowing him to get overthrown.
Oh, Crap!: His reaction when Blanque reveals that he has the Fugitoid.
Tracking Device: He uses one to search for the Fugitoid in "World Collide, Part 1".

Zog

https://static.tvtropes.org/pmwiki/pub/images/zog.png

Voiced by: David Zen Mansley

Zog: For the Republic! For victory!

A Triceraton soldier who gets stranded on Earth. Due to the planet's atmosphere, he comes to believe that the Turtles are Triceraton commanders and helps them in a mission against the Foot Clan.

Adaptational Badass: In the original comics, he's slain by one of the Shredder clones^notemade from worms, it's a long story. Here, he can take the actual Shredder in a fight and survives getting backstabbed by him.
Adaptational Late Appearance: In the original comics, he appeared in the "Return to New York" storyline. Here, this storyline had already been adapted in Season 1, and Zog appears in Season 2's "Rogue in the House" two-parter.
Cloudcuckoolander: He thinks the Turtles are Triceraton commanders and sees the Foot as goons of the Federation. Justified, since Earth's atmosphere effected his brain and he wasn't thinking straight.
Dies Differently in Adaptation: In the original comics, he was killed by the Shredder Mutants. In this series, he sacrifices himself in order to take out Shredder.
Early-Bird Cameo: He made a brief appearance in "Secret Origins, Part 1", where he falls down a tunnel and into the sewers.
Heroic Sacrifice: He sacrifices himself in order to finish Shredder once and for all. He doesn't succeed.
The Juggernaut: He can go through dozens of Foot ninjas and destroys several robots. He even overpowers Hun, picks him up and throws him off the ship.
Large Ham: Most of his dialogue is of the "Glory to the Republic!" and "Death to the Federation" sort.
Undying Loyalty: Technically, to the Triceraton Republic. And since his mind isn't straight, he's very loyal to the Turtles, thinking they are Triceraton commanders.

The Triceraton All-Stars

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2022_01_29_101718.png

Voiced by: David Zen Mansley (Monza Ram)

Famous, undefeated Triceraton gladiators.

Blood Knight: Most gladiators are condemned convicts, but the All-Star team do it by choice (as Monza Ram is seen unrestrained and guarding Professor Honeycutt at one point).
The Paragon Always Rebels: They are respected champions of the Triceraton Gladiator Games and trusted subordinates of the Prime Leader. After they lose a match, inadvertently letting the Turtles and Professor Honeycutt escape, they are sentenced to death themselves. Rather than loyally accept this fate, they join Traximus's rebellion and start working toward Prim Leader Zanramon's downfall.
Spikes of Villainy: They are sinister gladiators with spiked gauntlets (Monza Ram's is particularly fierce-looking) who are sent against the Turtles. Averted after their Heel–Face Turn.
The Voiceless: None of them besides Monza Ram ever speak.

Zed and Raz

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2022_01_29_101812.png

Voiced by: Wayne Grayson and Mike Pollock

The Gladiator Games announcers.

Bantering Baddie Buddies: They're chatty sports announcers who work for the villain and have an established rapport.
Punch-Clock Villain: They're abetting a vile blood sport, but it's an entrenched part of their culture and they show more respect than malice toward the Turtles while watching them compete.

Gruell

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2022_01_29_101600.png

Voiced by: Wayne Grayson

The jailer who watches over the imprisoned gladiators.

Fat Bastard: He's the fattest triceraton in the show, and after Prime Minister Zanramon, the cruelest.
Off Screen Karma: He never suffers any comeuppance beyond some minor humiliation, but he's presumably put out of a job after his enemy Traximus overthrows Zanramon.
Oral Fixation: One of his horns has been broken off and replaced with an ivory prosthetic. Gruell occasionally removes the prosthetic to use as a toothpick.
Wardens Are Evil: Gruell watches over condemned gladiators and delights in mocking them, whipping them, and serving them poor food. After the Turtles cross him, he tries to send them into the arena without their weapons.
Whip of Dominance: He's a sadistic jailer who carries a whip and is happy to use it on the prisoners.

Underground Mutants

As a whole

There are more than just three

Humans who were kidnapped by the Foot and experimented upon, turning them into the monsters that lurk in the caverns beneath the city.

Canon Foreigner: All of them were created for this series.
Code Name: They were each given these by the Foot.
Earn Your Happy Ending: Oh boy, do they go through hell:
- Firstly, they were kidnapped by the Foot and turned into mutants. Due to the mutations, they were all slowly going feral and there seemed to be no hope in finding a cure.
- Secondly, in the "Notes from the Underground" three-parter, they met the Turtles and by the end seemed to be cured...until they step out of the Crystal Moon's light (what cures them) and revert back to being mutants. This forced them to stay near the Crystal Moon until the Turtles could find a cure.
- Thirdly, the Crystal Moon eventually fell, reverting them back into the feral mutants that they were before. Fortunately for them, in "Return to the Underground", the Turtles return with a proper cure and they return to the surface, more overjoyed than anyone can imagine.
It Can Think: Well, played with. When they first freed themselves from the Foot and attacked them, the scientists were surprised that they were intelligent at all. However, as time progressed, their minds have been slowly deteriorating and are practically going insane.
No Name Given: Four out of the seven mutant's names, code name or otherwise, are never revealed.
Only Known by Their Nickname: Each of them was given a code name by the Foot. This is taken up to eleven, since they also don't know their true names, referring to each other with their given code name. Played with, as we only know three out of the seven mutants' nicknames and we later discover Quarry's real name: it's Sydney.
Pay Evil unto Evil: The underground mutants are fairly benevolent creatures^note, but after getting free, they enacted brutal revenge upon the scientists who'd enslaved and mutated them.
Was Once a Man: All of them were once humans who were kidnapped by the Foot and turned into mutants.
What Happened to the Mouse?: Quarry mentions that at least two other mutants disappeared while searching the tunnels (presumably kidnapped by the High Mage), but they never appear in the Y'Lyntian city.
With Great Power Comes Great Insanity: After being experimented upon by the Foot, their minds have been slowly deteriorating. By the time the Turtles meet them, 4 out of the 7 mutants have gone feral and aggressive, and when the Turtles return to the Underground, all of them have gone feral.

The Others

https://static.tvtropes.org/pmwiki/pub/images/feral_mutants.png

Leo: Why do you have to keep them out?

Quarry: Because they attack us. They are violent, uncontrollable. Their minds have deteriorated.

Four Underground Mutants whose minds have deteriorated. They wander the caverns aimlessly and attack anything on sight, including the Turtles, the non-feral mutants and each other.

The Berserker: All of them. They will attack anyone on sight, including each other in "Return to the Underground".
Big Creepy-Crawlies: The blue mutant resembles an insect.
Convection, Schmonvection: In "Return to the Underground", the spider mutant is hit by Raphael and falls into molten lava, yet she easily just shrugs it off and gets up from it as if nothing happened.
Cyclops: The stone mutant, that resembles Stonebiter, has one eye.
Evil Counterpart: Three out of the four mutants resemble more evil, feral versions of Quarry, Razorfist and Stonebiter.
Evil Is Bigger: They are more feral and brutal than Quarry, Stonebiter and Razorfist. Not only that, but they tower over them.
Gender-Equal Ensemble: When they are reverted back to their human form, they are revealed to be this.^note
Giant Spider: The four-legged mutant resembles a spider.
No Name Given: Unlike the non-feral mutants, their names, code names or otherwise, are never revealed.
Named by the Adaptation: In the video game adaptation, the red scorpion mutant was named "King Nail" and served as the final boss for the "Notes from the Underground" series of levels.
Spikes of Villainy: The stone mutant has multiple spikes across his back made from stone, while the red scorpion mutant has more natural-looking protrusions.

Y'Lyntians and their servants

Y'Lyntians

The former inhabitants of the island of Y'Lyntias. Long ago, they created an advanced civilization with technology far more advanced than any contemporary human technology. However, in recent years, they are forced to live underground, waiting for the perfect moment, when they can resurrect their former empire.

Ambiguously Human: They certainly come from Earth, but they are so...odd. Most of them have pale skin, sharp claws, unnatural-looking eyes and most of them are bald (with hair on the sides). Hell, the aliens of the Federation look more human than they are.
Atlantis: Their history inspired the legend of Atlantis.
Beneath the Earth: After the fall of their empire, they were forced to take refuge in the caverns of the Earth, where they can wait for the perfect moment to resurrect their empire.
Dying Race: After the fall of their empire, their numbers have been slowly declining. Still, there are at least a few hundred of their race left, since in "The Entity Below", we see the underground city entirely populated. Versallia also mentions at the end of the episode that there are more surviving Y'Lyntians, who are more peaceful than the main group.
Fantastic Racism: During the height of their empire, most considered humanity to be inferior. Nowadays, while there are those, who still believe this, others have moved on.
Master Race: They consider themselves superior to humanity. Due to this, they enslaved many individuals and mutated them in order to carry out specific roles better^note.
Power Crystal: The backbone of their advanced technology. Years ago, a series of meteorites fell on their island. From the meteorites, they salvaged crystals, which they used to create more advanced tech than what humans at the time had ( to specify, it was the time of Ancient Greece).
Small Role, Big Impact: The Y'Lyntians only make five appearances (two in person, two in flashbacks, and one in cocooned states), but their influence is felt in some way across all seven seasons. They originally built the heroes' lair as an observation post. Their presence plays a role in the two episodes of the Underground mutants arc where they don't actually appear. And each of their three former Slave Races is the focus of an episode, and Raptarr from the third such race becomes a recurring character for the rest of the show.
When the Planets Align: When this happens, their energy crystals are overcharged with energy. They plan on using said energy to bring the island of Y'Lyntias from the depths of the ocean, thereby causing massive environmental disasters and eliminating most humans on the planet.
You All Look Familiar: As can be seen in their character picture, most Y'Lyntians resemble each other. The only ones that are distinct, are Versallia, who's the only female Y'Lyntian we see, and the High Mage, who resembles the normal Y'Lyntian but with a hood and red eyes.

High Mage

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2021_03_25_183515.png

Voiced by: David Zen Mansley

High Mage: I refuse to let this city die! There's so much to pass on. They must stay, and so must you!

The High Mage, also known as the Entity, is a high-ranking Y'Lyntian, who was given the task of monitoring the outside world, while his brothers would be in cryogenic sleep, waiting for the moment, when they can retake the world they once ruled.

Bald of Evil: He's bald, though his has hair on the sides of his head.
Evil Sounds Deep: Has a deep voice that accompanies his sinister looks.
Face Framed in Shadow: During his first few appearances in "Notes from the Underground, Part 3", his face is largely obscured.
Good Eyes, Evil Eyes: His eyes are narrow like a reptile.
Hoist by His Own Petard: Throughout "Notes from the Underground, Parts 2 and 3", he uses light orbs to capture the Turtles and the Underground Mutants and incases the mutants in ice. At the end of Part 3, Mikey sets him flying through a wall, dropping them. Mikey then picks them up, throws them at him and incases him in ice, to his dismay.
In the Hood: During his first few appearances, he wears a hood that obscures his face.
Last of His Kind: He claims to be this in "Notes from the Underground, Part 3". Of course, the Turtles eventually discover that he really was lying.
Horrifying the Horror: He completely horrifies Quarry.
Living Lava: In "The Entity Below", he discovers that the Turtles have returned and summons four lava monsters to hunt them down.
Loners Are Freaks: The Turtles assume he has gone mad due to being alone for so long, though they feel sympathy for him due to this. In reality, he was always a freak.
Power Crystal: He uses one of these to control the city around him.
Really 700 Years Old: In "The Entity Below", the High Mage is implied to have been wandering the city and the Underground for at least several thousands of years.
Sympathy for the Devil: In "Notes from the Underground, Part 3", the Turtles genuinely feel sorry for him after his defeat, because he was alone for so long and just wanted company. Of course, when they discovered in "Return to the Underground" that he really wasn't alone, they took back their sympathy for him.
Technicolor Eyes: His eyes have red sclerae.
White Hair, Black Heart: He has white hair and wants to retake the world that his race once ruled by eliminating most of humanity and turning the rest into slaves.

Versallia

Voiced by: Caren Manuel

Versallia: I am an Y'Lyntian, but I am not like the others. We must stop them.

A Y'Lyntian woman, who detests the cruel and evil ways of her people.

Before the Dark Times: After freeing the Turtles from the cell they were placed in, she brings them to a room, where she explains the history of the Y'Lyntians before they were forced to move underground. Played with, as the times were good for the Y'Lyntians, but not very much for humanity.
The Smurfette Principle: She is the only Y'Lyntian woman we ever see in the series.
Token Heroic Orc: She's the only Y'Lyntian we see, who doesn't want to rule the world with an iron fist. Kind of subverted by the end of "The Entity Below", as she mentions that there are other, more peaceful Y'Lyntians like her.
Was It Really Worth It?: She asks herself this after stopping the other Y'Lyntians by sabotaging the crystals and sinking the city in lava, presumably killing them.

Green Men

https://static.tvtropes.org/pmwiki/pub/images/green_man_5.png

Green Men, also known by the Y'Lyntians as beasts-of-burden, were humans, who were enslaved and mutated with the power of the crystals into beasts, who performed manual labor.

Gentle Giant: They are generally peaceful and benevolent.
Made a Slave: All Green Men were former human slaves.
Monster Is A Mummy: The Green Man from "The Monster Hunter" is revealed to be this.
Offscreen Moment of Awesome: It isn't shown how, but at least some of the Green Men survived the destruction of Y'Lantias, which is impressive considering that they couldn't just fly away like the Avians or swim away like the Merpeople.
Phlebotinum Rebel: They eventually rebelled against the Y'Lyntians alongside all the other servants and nearly destroyed their entire civilization.
Posthuman Nudism: They were clothed when they had been human, but after their mutation, they now walk around in the buff.
Real After All: In "The Monster Hunter", there really is a Green Man in the woods and the Turtles do their best to stop Dr. Finn from capturing it.
Was Once a Man: All Green Men were once humans, who were mutated into the hulking beasts they are in order to fulfil a specific role. In their case, it's manual labor.

Merpeople

The Merpeople, also known as the Water-Breathers, were the aquatic servants of the Y'Lyntians. In recent years, their numbers have been dwindling, but the Turtles set them on a path to recovery.

Adaptational Backstory Change: In the original comics, they were just a race of Fish People. In this series, they were humans, who were turned into their current forms by the Y'Lyntians.
Creepy Good: The merpeople are a civilized race who are just trying to be left alone while protecting their own. Still they look pretty creepy when they're angry and have several scenes of ominously following the heroes during their rafting trip.
Last of His Kind: When the Merwoman telepathically communicates with April, she claims that the five of them are the last of their kind. Though, at the end of the episode, the Turtles help them save their eggs, setting them on a path to recovery.
Lightning Bruiser: The Merpeople are strong enough to break their shackles during the Battle of Y'Lyntias, and move nearly as fast as the Teenaged Mutant Ninja Turtles in combat.
Made a Slave: All Merpeople were former human slaves.
Non-Mammal Mammaries: The Merwoman the Turtles encounter in "Sons of the Silent Age" has notable breasts. Possibly justified, since Merpeople were originally humans.
Phlebotinum Rebel: They eventually rebelled against the Y'Lyntians alongside all the other servants and nearly destroyed their entire civilization.
Posthuman Nudism: They were clothed when they had been human, but after their mutation, they now walk around in the buff.
Really 700 Years Old: When the Merwoman telepathically communicates with April, she's revealed to have been a young child during the time of the Y'Lyntians.
The Smurfette Principle: Out of the five remaining Merpeople, only one of them is female.
Was Once a Man: All Merpeople were once humans, who were mutated into the aquatic dwellers they are in order to fulfil a specific role. In their case, it's hunting for food.

Avians

The Avians are the sky servants of the Y'Lyntians. After they rebelled and freed themselves, they created a city in the sky, where they can live in peace.

Fantastic Racism: The Y'lyntians forced the Avians to live in a floating bird cage due to feeling they "befouled" their city.
Hidden Elf Village: After freeing themselves from the Y'Lyntians, they created an undetectable city in the skies that can only be found with a crystal diadem.
Was Once a Man: All Avians were once humans, who were mutated into the these forms in order to fulfil a specific role. In their case, it's patrolling the skies.
Winged Humanoid: After being mutated by the Y'Lyntians, they grew wings and could fly.

Mephos

Voiced by: Dan Green

Mephos: We are gods among insects!

An Avian who wants his race to come out of hiding and take over the surface world.

Artificial Limbs: His real wings were removed as punishment for his rebellion. As a result, he now has back metal wings.
Combat Pragmatist: He'll happily attack Raptarr if he's distracted or target his already-wounded spots to take him out.
Crippling the Competition: He was punished for crimes against his race by having his wings torn from his back and being forced to live as a human.
Dark Is Evil: Mephos is black haired with black (metal) wings, and pale grey skin.
Fantastic Racism: Mephos is constantly referring to residents of the surface by monikers such as insects and apes with a sneer. He even uses the word "befouled" indicating that he is not so different from his ancestors' slavers.
Feather Flechettes: His cybernetic wings allow him to do this.
We Can Rule Together: Mephos makes a half-hearted effort for Raptarr to join him.

Time Masters

Lord Simultaneous

Voiced by: David Lapkin

Simultaneous: Let me show you the true and good powers of the Time Scepter.

The lord and master of all time and space, Lord Simultaneous is the mentor of Renet and an ally of the Turtles. He possesses an object called the Time Scepter, which seems to have a mind on its own.

Good All Along: In "Time Travails", when he meets the Turtles for the first time, Renet says that he "wants to kill her", so they assume he's evil. At the end of the episode, they realize that he's just her annoyed mentor.
Donatello: Dusting? This was all about dusting?!
Hidden Depths: In general, he's very cynical, uncaring and even cold-hearted at times, but in "The Real World, Part 2", he shows his caring side when he sympathizes with Daimyo and brings his son back to life in order for Daimyo to raise him right this time.
Huge Holographic Head: He appears as one of these in "Time Travails".
Human Alien: He looks like a human, but in reality he comes from the 79th Dimension.
It Can Think: In "Time Travails", he mentions that the Time Scepter seems to have a mind of its own. In "The Real World, Part 2", this is proven true when it interacts with the Daimyo's War Staff in order to put everything as it should be.
Meaningful Name: He can simultaneously see what is happening at any moment, at any time.
No Celebrities Were Harmed: His voice actor plays him with a Gilbert Gottfried impression.
Pet the Dog: In "The Real World, Part 2", after seeing how devastated Daimyo is due to the death of his son, Simultaneous brings his son to life in order for Daimyo to raise him right this time.
The Stoic: In "Time Travails", his reactions to the Turtles' and Renet's time shenanigans are strong, but self-contained, annoyance. Hell, in the same episode, he gets attacked by Ultimate Drako and he doesn't even react, just zaps him with the Time Scepter, which freezes him in place.
Time Master: He's the current lord of all time and space.

Savanti Romero

^{Click to see his original form}

Voiced by: David Zen Mansley

Savanti to Renet: Silence! I don't know how Lord Simultaneous puts up with you, but I will soon put him out of that misery!

The former apprentice of Lord Simultaneous, Savanti Romero wants to obtain the Time Scepter from his former mentor and rule all of time and space.

Adaptational Late Appearance: In the original comics, he first appeared in issue 8 of volume 1. In this series, most of the stories from the first volume had already been adapted in Seasons 1 and 2, and Savanti makes his first appearance in Season 3.
Ambition Is Evil: He wants to rule all of time and space.
A Pupil of Mine Until He Turned to Evil: He was Lord Simultaneous' apprentice, who attempted to steal the Time Scepter. Due to this, he was banished to the Medieval Ages and turned into a demon-looking monster.
Blade Below the Shoulder: His bone armor from "Return of Savanti, Part 2" has these.
Death by Adaptation: In this series, he gets killed during his battle with the Turtles in the "Return of Savanti" two-parter. In the original comics, he survived the encounter.
Death by Materialism: In "Return of Savanti, Part 2", Donatello pushes the Time Scepter to fall in the waters below him. Savanti tries to catch it and he does, only for the lightning that he ordered to hit Renet instead hit him, causing him to plummet to the waters below.
Dragon Rider: In "Time Travails", he's shown to ride a red dragon who turns out to be Ultimate Drako in disguise .
Establishing Character Moment: In "Time Travails", he is first seen when Renet uses the "Orb of Hindsight". Then, he is gloating about how he's going to obtain the Time Scepter and have his revenge upon the time lord that banished him, establishing his motivation and plans.
Evil Laugh: He's quite prone to doing this.
Evil Sorcerer: He can use spells to raise armies of dead soldiers and to enlarge grotesque insects.
Evil Sounds Deep: He has a deep voice that accompanies his demon-looking form.
From Bad to Worse: When the Turtles met him for the first time in "Time Travails", he was already an evil sorcerer who wanted to kill Lord Simultaneous and rule the universe. When they meet him again in the "Return of Savanti" two-parter, he wants to use the Time Scepter to erase the Turtles and humanity from existence.
- This also happened to him in "Time Travails". As he hated being banished to the Medieval Ages, at the end of the episode, Lord Simultaneous banishes him even further to the prehistoric times. Though he ends up using his predicament to his advantage in the "Return of Savanti" two-parter.
Horned Humanoid: After he attempted to steal the Time Scepter, Lord Simultaneous turned him into this.
Horns of Villainy: In his demonic form, he has demon-like horns.
Killed Off for Real: He's killed at the end of the "Return of Savanti" two-parter.
Magic Staff: In the "Return of Savanti" two-parter, he's using one of these to control the dinosaurs around him.

Pointy Ears: In both his original and demon forms.
Raptor Attack: With his magical staff, he controls a pack of raptors.
Revenge: His main motivation:
- In "Time Travails", he wants to obtain the Time Scepter and kill Lord Simultaneous, who banished him to the Medieval Ages.
- In the "Return of Savanti" two-parter, he wants to get rid of the Turtles and humanity as a whole by making the asteroid that killed the dinosaurs miss Earth, thereby erasing them from existence.
Skeletons in the Coat Closet: In "Return of Savanti, Part 2", he gets armor made from dinosaur bones.
Terror-dactyl: Savanti rides a pterosaur in "Return of Savanti, Part 2" and uses it to capture Renet.
Time Master: He was Lord Simultaneous' former pupil. Needless to say, he's way more experienced with using the Time Scepter than Renet is.
Was Once a Man: A human-looking alien at least. After he attempted to steal the Time Scepter from Lord Simultaneous, he was turned into a demon-looking monster and was banished to the Medieval Ages.

Alternate Worlds

Characters from "Reality Check"

Super Turtles

Shellectro (upper right), Blobboid (lower right), Graviturtle (upper middle), and Griddex (left)

Voiced by: Michael Sinterniklaas (Graviturtle), Sam Riegel (Shellectro), Frank Frankson (Griddex) and Wayne Grayson (Blobboid)

The Super Turtles are alternate counterparts of the Turtles, who battle crime with their super-powers.

Alternate Self: As a whole, they are alternate counterparts to the main Turtles, but to be more specific:
- Graviturtle is the alternate counterpart of Leonardo and the leader of the Super Turtles.
- Shellectro is the alternate counterpart of Donatello and can use his electric powers to manipulate technology.
- Griddex is the alternate counterpart of Raphael and can sizeshift.
- Blobboid is Mikey's alternate counterpart, but is a bit more serious.
Danger Room Cold Open: Mikey first meets them when they are in a training simulation.
Gravity Master: Graviturtle's super-power.
Home Base: Their main head-quarters is a shell-shaped building in the middle of the city.
Meaningful Name: With the exception of Griddex:
- Shellectro has powers over electricity.
- Graviturtle can manipulate gravity.
- Blobboid is a Blob Monster.
Mirror Self: Zig-zagged. Blobboid is a bit more serious than Mikey, but compared to the other Super Turtles, he's the most laid back.
No Longer with Us: When Mikey asks what happened to their version of Splinter, all he gets is that "we lost him"... Mikey realizes what that means at the end of the episode. They lost him to evil because he's known as Sliver, the Big Bad of their world.
Odd Name Out: While the other Super Turtles are named after their powers, Griddex can change his size, but his name doesn't reflect his powers.^noteat least to such an obvious degree
Shapeshifter: Blobboid's second super-power. He uses this to masquerade as Mikey and trick Sliver into letting him out.
Shock and Awe: Shellectro's super-power. With this, he can manipulate any technology he touches.^noteaka disarming a bomb and so on
You Are Not My Father: They do not consider Sliver their father after he turned evil.

Sliver

Voiced by: Darren Dunstan

Sliver: Behold, the end and the beginning!

The former mentor of the Super Turtles, who turned evil.

Adaptational Superpower Change: In the original comics, he didn't have any powers, relying on his skills as a fighter. Here, he has the abilities of his sons.
Adaptational Villainy: In the original comics, he was still a villain, but was more of a dragon to Dr. Shreddarius. In this series, due to Dr. Shreddarius being Adapted Out^note, Sliver has been made the Big Bad of the Super Turtles.
All Your Powers Combined: Since he trained the Super Turtles how to use their powers, he also has them and can use them even better.
A Pupil of Mine Until He Turned to Evil: Inverted. He turned to evil, not his students.
Big "NO!": He lets one out when the bomb destroys his tower along with him.
Even Evil Has Loved Ones: Despite them being his arch-enemies, he truly loves his sons and wants to rule the world together with them.
Evil Counterpart: He's an evil alternate counterpart of Splinter.
Evil Mentor: He was once the Super Turtles' mentor, who now is a villain.
Hoist by His Own Petard: In "Reality Check", he plans to use a bomb to destroy everything with the exception of his tower. At the end, Shellectro reprograms it, so it would destroy everything inside the tower.

Red Eyes, Take Warning: He has bright glowing red eyes.
Spikes of Villainy: His armor has bone-like spikes.
We Can Rule Together: He wants to take over the world and rule it with his sons.

Characters from "Across the Universe"

Team Fitts

Falcon and Methania

Falcon

Methania

Voiced by: David Wills (Falcon) and Bella Hudson (Methania)

A team who participates in an intergalactic charity race. Falcon acts as the pilot, while Methania acts as the navigator.

Bare Midriffs Are Feminine: Throughout the entirety of "Across the Universe", Methania sports such an outfit.
Forgotten First Meeting: In the Season 6 episode "Race for Glory", it is implied that Raph met Falcon when the latter was a child. Falcon shows no indication that he remembers Raph in "Across the Universe" from Season 3. However, there is no confirmation that these Falcons are the same person and it is possible that the kid Falcon was actually a descendant of the adult Falcon instead.
Human Alien: Falcon certainly looks human, but he also certainly doesn't come from Earth. May have been subverted in the Fast Forward episode "Race for Glory", where Raphael seems to meet a younger version of him.
Red Is Heroic: Played with. They are more heroic than their opponents, but still Falcon wanted to win at all costs much like them. Though Raph eventually teaches him that "winning without honor, that's just not winning".
Red Oni, Blue Oni: Falcon and Methania. Falcon is the more brash and hot-headed one. Matheria is calmer, far-thinking, and more reasonable. Their color scheme even matches.

Commissioner Morrey

https://static.tvtropes.org/pmwiki/pub/images/morrey.png

Morrey: A little danger never hurt anybody.

The man who organized the race that Team Fitts participates in.

Bald of Evil: He doesn't have any hair on his head and has an utter disregard for the lives of his racers.
Corrupt Corporate Executive: Commissioner Morrey deliberately sends the racers into dangerous terrain, such as tunnels filled with man-eating worms and a rainforest filled with hostile tribal cannibals on the grounds that it's good for ratings if some of the racers get hurt or even killed.
Engineered Public Confession: Methania uses a hidden camera to expose Commissioner Morrey by getting him to brag about how he's sending the races to their deaths for ratings, and he can just get more racers.
Non-Action Big Bad: He's the Big Bad of "Across the Universe" since he sends the racers to their deaths just for the ratings, but he can't defend himself at all.
Rubber-Forehead Aliens: He's basically a pink bald human.

Team Koyoshada

Tripper Nitro and Jag Majoria

Voiced by: Unidentified actors.

Team Fitts's over-competitive and underhanded rival racers.

Sore Loser: Tripper throws his helmet to the ground after coming in second by a few seconds.
Ungrateful Bastard: After Raphael and Falcon save them from hostile Mud Riders, Tripper and Jag resume the race and leave them to fare for themselves with almost no hesitation.

Nobby Blue

Voiced by: Jonathon Todd Ross

The Planet Racers announcer.

Reasonable Authority Figure: He expresses concern for the racers when Morrey is exposing them to danger and helps expose his corrupt superior with an Engineered Public Confession.

Characters from "Same As It Never Was"

The Future Turtles

Future Mikey

Future Leo

Future Raph

Voiced by: Wayne Grayson (Future Mikey), Frank Frankson (Future Raphael), Michael Sinterniklaas (Future Leo)

Future Mikey: We were a team. Without you, it just didn't work.

In a Bad Future, the Turtles went on their separate ways due to Donatello disappearing and the victory of the Foot Clan. But when Donatello reappears one day, they reunite and go on one last battle against the Shredder.

Alternate Self: They are from an alternate dimension according to Peter Laird and it is confirmed by Turtles Forever.
Ambiguous Situation: Is Leonardo blind or did he just take to wearing Sunglasses at Night to look more badass? It's hard to tell.
- Word of God confirms that Future Leo is not blind, just scarred.
An Arm and a Leg: Mikey doesn't have a left arm.
Badass Longcoat: Future Leo wears one of these.
- Actually, his attire is strikingly similar to that of the Guardians, earlier in the series, implying he may have become one or at least helped himself to a spare...
Eyepatch of Power: A variation. A part of Future Raphael's bandana is stitched.
Family-Unfriendly Death: All of them get killed in cruel and brutal ways during their assault against the Shredder. In order:
- Future Mikey gets overwhelmed by the Karai bots and brutally slashed and mauled to death.
- Future Leo fights Future Karai one-on-one and defeats her. As he is about to finish her, a Karai bot appears behind him. He manages to take the bot out, giving Karai just enough time to backstab him.
- After seeing Future Leo getting killed, Future Raphael gets infuriated and attacks Karai, only for him to get slashed and killed by her as well.
Future Badass: All of them. They were already badass in the present, but in the future they reach new levels. Given the Time Skip, it's justifiable:
- First encountered and least recognizable is Michelangelo - who within the first couple minutes not only takes out a patrol on his own (with spiked nunchaku, no less), but destroys several tanks and a helicopter with one of the goons' own guns. This contrasted with the bubbly, hyperactive, superhero-idolizing version of Mikey present throughout the rest of the show. It's a little jarring and yet completely awesome.
- Raphael is missing an eye and wears a bomber jacket.
Losing the Team Spirit: Future Mikey explains to Donnie how after he disappeared, the team just fell apart. That Donatello was The Heart of the team and without him, everyone went on their separate ways.
Putting the Band Back Together: After Donatello reappears, the Future Turtles reunite one last time in order to take out the Shredder.
Same Character, But Different: All of them, though special mention goes to Mikey. He has changed from the turtle making jokes and being generally hyperactive to the turtle that in the first couple of minutes defeats an entire Foot squad, including a helicopter. He is disturbingly accepting of the fact that the world sucks, and thoroughly willing to call Don out for "abandoning" them. And all of this is justified due to the Time Skip.
Took a Level in Cynic: Mike has lost practically all of his fun-loving and laidback nature as a result of everything that's happened, sort of like a proto-Last Ronin.
This Is Unforgivable!: Occurs to Future Raphael, when Future Leo gets killed.

Future April

Voiced by: Veronica Taylor

Future April: Donatello! You came back!

After the Shredder's victory, April has been leading a resistance against him.

Future Badass: Certainly. In the present, she was still a badass^note, but in the future, she leads the resistance against the Shredder. She even uses a bazooka to fell Karai at one point.
Rebel Leader: She is the leader of at least a part of the Resistance against the Shredder.
Same Character, But Different: In the present, April is the owner of an antique shop, but is still capable in a fight. In the future, she leads a part of the Resistance against the Shredder.
Sole Survivor: She's the only future character from "Same As It Never Was" to survive the assault against the Shredder.

Future Hun and Stockman

Voiced by: Greg Carey (Future Hun) and Scott Williams (Stockman)

Future Stockman: Don't be impolite, Hun. Say hello.

Future Hun: Greetings, Donatello.

When Hun and Baxter Stockman were about to be executed by the Shredder, they were rescued by April and her Resistance. Due to this, they joined her side in order to take out the Foot Clan.

Admiring the Abomination: When the group is outlining to Donnie how they couldn’t possibly reach the Shredder, Stockman chimes in that even if they did, they couldn’t beat his armor - he designed it, after all.
Alas, Poor Villain: Even when Hun begs the Shredder to take him back, it’s very easy to pity him for how far he’s fallen, only to be met with a sadistic crushing by his former master.
Brain in a Jar: Future Stockman is this, though that isn't really different from his present-day counterpart.
Despair Event Horizon: Hun clearly crossed it when Shredder decided to execute him, leading to his current state. It’s a good look at what would’ve happened in the prime timeline had his streak of bad luck in Season 3 kept going.
Formerly Fit: Hun is extremely muscular in the present day. In the future, he is wheelchair bound and evidently he doesn't get much exercise and has become very fat.
Hair Today, Gone Tomorrow: In the present, Hun had blonde hair with a ponytail. In the future, he is bald. Though his present day counterpart's hairstyle does look a little bit like he is suffering from male pattern baldness.
Heel–Face Turn: Off-screen, they were rescued from execution. This made them join April's side in the battle against the Shredder.
How the Mighty Have Fallen: Both of them get hit with this:
- Stockman, even if he was mistreated, was one of the highest ranked subordinates of the Shredder, designing weapons and armor for him. In the future, he was about to be executed and is attached to Hun, one of the people he hated the most permanently. Still, he continues to design weapons and armor, but now for the Resistance.
- Hun gets hit the hardest with this. He was once The Dragon to Shredder, even when he later shared the role with Karai. He had insane strength for a human and was capable of defeating the Turtles quite easily. But in the future? Oh boy. The 30 years did him dirty. He's now bald, is a cripple, his strength is gone and is on the Shredder's kill-list.
Killed Off for Real: Both of them get killed by the Shredder, when he stomps on them.
The Load: Hun due to being crippled and having lost everything. Stockman averts this as he is now The Smart Guy for the resistance.
Rewarded as a Traitor Deserves: When Future Hun begs the Shredder to be on his side again, much to Future Stockman's dismay, Shredder simply stomps on them, killing them both.
The Smart Guy: Stockman serves as the chief engineer and weapon designer for the resistance.
Those Two Guys: Very much not by choice, thanks to Stockman being implanted in Hun’s shoulder.

Future Shredder

Voiced by: Scottie Ray

Future Shredder: I want Donatello's head brought before me! With or without his body!

After Donatello disappeared, the Shredder was victorious. He had taken over the entire planet and rules it with an iron fist. Now he wants to expand his empire to the stars, wanting to conquer the galaxy.

Characters from Usagi's world

Tomoe Ame

Voiced by: Rachael Lillis

Tomoe Ame: Ninja Scum!

A samurai cat girl who's an ally of Usagi and Lord Noriyuki.

Action Girl: She's very capable in a fight, even if she gets captured.
The Bait: She's used by Lord Hebi as this to lure both Noriyuki and Usagi to him.
Cat Girl: She's a more anthropomorphic example.
Damsel in Distress: She gets captured by Lord Hebi's mole mooks at the beginning of "The Real World, Part 1".
Good All Along: An example from her perspective. She initially thinks that Leonardo is a minion of Lord Hebi and attacks him on sight. After he defeats and spares her, she realizes that he isn't her enemy.
Take Me Instead: After she's defeated by Leonardo, she offers herself to be taken instead of Noriyuki, not realizing that Leo is not a minion of Lord Hebi.

Lord Hebi

https://static.tvtropes.org/pmwiki/pub/images/hebi_1.png

Big "NO!": He lets out one when his plans get foiled.
Card-Carrying Villain: Hebi openly admits that he only seeks to loot and pillage once he takes Noriyuki's lands and sees such a dream as beautiful.
Meaningful Name: Hebi is a Japanese word for "snake".
Orcus on His Throne: He largely sits back in his castle, giving orders to his mooks.
Reptiles Are Abhorrent: Obviously. Gets invoked when Leo says this:
Leo: It's guys like you that gives us, honorable reptiles, a bad name.
Revenge: His motivation in "Samurai Tourists". He hires Kojima in order to take out Gen, Usagi and Leo, all of who foiled his plans.
Snakes Are Sinister: He's an evil snake lord, who wants Lord Noriyuki to be assassinated
Sssssnaketalk: Hebi predictably speaks like thisssss in "The Real World" part 1 and "Samurai Tourist".

Would Hurt a Child: He sends his assassins to kill Lord Noriyuki, who is just a kid.

Tunneling mole ninjas from Usagi’s dimension who serve Lord Hebi as kidnappers and thugs.

Fast Tunneling: They can dig through the ground at rapid speeds.
What Happened to the Mouse?: They are never seen again after capturing Gen and Lord Noriyuki.

Chizu and the Neko Clan

Voiced by: Caren Manuel (Chizu)

A group of humanoid feline ninjas who work for Lord Hebi.

Adaptational Villainy: In the comics, Chizu and her clan are honorable warriors and allies of Usagi. In their sole appearance in the show, they fight Usagi on behalf of an odious villain who wants to kill a young child and usurp his feudal position.
Cats Are Mean: They are cat-like assassins and thugs with no apparent depth.
Consummate Professional: Chizu shows deep focus and no emotion while accepting orders to attack the heroes and then giving her men orders during the attack.
Faceless Mooks: Most of them wear face-concealing black masks and they act as enforcers.
Screw This, I'm Outta Here: The ninjas present for the climax of their one episode run away after The Cavalry arrives at Lord Hebi's castle.
What Happened to the Mouse?: Chizu is last seen delivering a message to the heroes halfway through her one episode.

Kojima

Black Cloak: He wears one of these before he encountered Usagi and Leo.
Evil Sounds Deep: He's an assassin, who talks in a very deep voice.
Mythology Gag/Continuity Cameo: Since Gen wore clothes in "Samurai Tourists" that made him resemble Rocksteady, it can be said that Kojima, the assassin boar, is a possible nod to Bebop.
Professional Killer: He was hired in order to kill Usagi, Gen and Leo.
Villainous Breakdown: Kojima remains quite confident for most of the battle, but after getting smacked around by Leo and seeing all the heroes about to gang up on him, he loses his cool.
Worthy Opponent: Kojima congratulates Usagi for the fight he's put up. Before trying to deliver the final blow, he promises to remember him.
"Take comfort in that."

Others

Bishop

^{Click to see him in 2105}

Voiced by: David Zen Mansley ^{Foreign VAs}Jean-Marc Delhausse (FR)

Bishop: Very well, Michelangelo. When you scream my name, pleading to make the pain stop, begging for mercy, you may call me Bishop.

A government agent who will do absolutely anything to protect Earth from alien invasions. Head of the Earth Protection Force.

Alien Blood: Despite being human. After he was impaled by a hook in one episode, one could briefly see a thick, silver-colored liquid seeping through his clothes.
Ambiguously Human: He was definitely human at some point, but after a certain event some 200 years ago, it's no longer clear what he is.
Anti-Villain: He genuinely tries to protect humanity from potential alien invaders. The problem is, he is sadistic, amoral, suffers a huge case of Fantastic Racism against aliens and mutants as a whole, and conducts horrible experiments to reach his goals.
The Atoner: In Fast Forward, it's revealed that he turned over a new leaf and was a key player in fostering the positive human-alien relationships that would lead to their peaceful coexistence in the future.
Back for the Finale: After being absent for the entirety of the final season, he makes a cameo watching April and Casey's wedding with approval.
Badass Bookworm: Bishop's a government operative who rightfully claims that knowledge is his business and he can easily beat the turtles, Hun and Karai.
Badass Longcoat: Part of his signature look is a long trenchcoat.
The Bad Guy Wins: In "Aliens Among Us". He stages an Alien Invasion and creates monsters to act as aliens to abduct the president so he can fake a rescue. The Turtles intervening does nothing to stop it as the president mistakes them for hostile aliens, letting Bishop pull off his fake rescue anyways.
Benevolent Boss: He can be stern or angry toward Stockman, but for the most part, shows genuine concern for his condition (if just because he still needs Stockman's knowledge) and, unlike the Shredder, never threatened to kill or mutilate him for his failures.
- Bad Boss: Implied to be this to the rest of his men, given that he threatened to use one for genetic research.
Big Bad Ensemble: He's the most prominent antagonist in the third season not aligned with the Foot. After the defeat of Ch'rell in the fourth season, he forms an ensemble with Hun and Karai, with Stockman as his Dragon.
Breakout Villain: He's introduced in the third season, and not only ended up becoming one of the Turtles' signature foes in the 2003 series, but eventually became popular enough to get included in the comics and appear in other adaptations as well.
Canon Immigrant: A character who talks while off-panel in one issue of the Mirage Comics has been confirmed by Word of God to be him.
Clark Kent Outfit: His default outfits make him appear average, but when he is shirtless, or wearing skintight bodysuits, his physique is comparable to that of Silver Sentry.
Clone Degeneration: He survived so long by regularly cloning himself in a new body that ends up degenerating after a while, forcing him to do it over and over again.
Combat Pragmatist: He ends up using his own tie to fight the Turtles, Karai and Hun and still continues to kick ass.
Dark Is Evil: As a villain, his suit is black.
Deadpan Snarker: He often communicates this way. Mostly before his Heel–Face Turn
(Baxter Stockman reluctantly informs Bishop on the outbreak of mutations in New York City)
Bishop: Doctor, do you have a theory on this?
Bacter Stockman: There could be any number of explanations really.
Bishop: Give me your favorite.
Enemy Mine: Twice:
- When the mutagen he used to create a fake alien invasion ends up unleashing mutants on New York, he teams up with the Turtles and Leatherhead to end it.
- In the fifth season, he is amongst the many villains who join force with the Turtles to stop Tengu Shredder.
Even Evil Has Standards: Is horrified when he learns the mutagen he used in his fake alien invasion caused an outbreak of mutations in New York.
False Flag Operation: After doing nothing during the Triceraton invasion (thanks to his deal with the Federation), his attack on the Shredder’s mansion, and the escape of the mutated T9581, the President is on the verge of shutting down the EPF. Bishop responds with one of these, creating a faux alien invasion to kidnap the President and make it appear as though Bishop is saving his life. It works marvelously well as the President, grateful for the apparent rescue, pledges full support to the EPF.
Four Eyes, Zero Soul: He's never seen without a pair of sunglasses, and he's a bad guy.
Freudian Excuse: In 1815, Bishop was a soldier in the War of 1812 who was abducted by aliens, being experimented on and genetically altered, turning him into the xenophobic Well-Intentioned Extremist he is in modern times who's willing to cross any moral boundary in order to keep Earth safe from alien incursions. Given his past, it's quite understandable why he became the man he is today, though in no way does this justify all the lives he's ruined and the people he's hurt. His actions become even less justified when you consider that some of the beings he's (tried to have) tortured such as Leatherhead, the Turtles, and Splinter, despite being byproducts of the alien Utroms' mutagen, are actually native to Earth and notably NOT aliens in any sense.
From Nobody to Nightmare: A mere soldier who was the victim of an extraterrestrial project, and went on to become an almost Ax-Crazy Covert Group leader who will do anything to get his point across, regardless of the consequences it may have.
Guns Akimbo: His most frequent weapons when using firearms.
Hated by All: In modern times, the Turtles, Splinter, Leatherhead, and even the Foot Clan thoroughly despise him and Raphael even went on record as to say he hated Bishop more than his Arch-Enemy Hun. Even an important political ally to Bishop like the President of the United States doesn't seem to like Bishop all that much and has chewed Bishop out for constantly acting on his own. And Baxter Stockman, the closest thing Bishop has to a friend in the show, quickly grew disillusioned with working under Bishop, based on how Bishop has constantly stalled him from working on a new human body or brought him back from the dead even though Stockman wanted more than anything to rest in peace.
Heel–Face Turn: In Fast Forward, he goes from wanting all aliens and mutants exterminated to helping to foster close relationships between them and humanity.
Heel Realization: In Fast Forward, he became a better person after an alien he was experimenting on saved his life, altering his view of extraterrestrials considerably.
He Who Fights Monsters: He was experimented on and never wants that fate to befall another human, but himself has experimented on aliens, regardless of their innocence. Not to mention his experimentations on Earthlings, including other humans.
Hypocrite: He wants for no other human to befall the fate of being experimented on by extraterrestrial forces, but has done the same to aliens themselves. This isn't even getting into the fact he's heavily implied to have mutated Finn in "Dragon's Brew", whose wedding he was the best man for. Furthermore, despite all his talk about protecting humanity from alien threats, he has no problem with killing off a large portion of humanity through integration of his slayer soldiers into the population and will easily threaten the President himself as part of a selfish plan to secure more organization funding.
Iconic Sequel Character: He's one of the most well-known characters in the 2003 incarnation, despite his first appearance being in Season 3, the midpoint of the series.
Implacable Man: Bishop is very hard to take down, provided you can actually get a hit in on him.
Improbable Weapon User: He'll use anything up to and including his tie and glasses in a fight.
Karma Houdini: Though he at least learnt from his mistakes and tries to atone for what he did.
Knight Templar: His noble intentions have turned him into a zealous maniac.
Leitmotif: He has a snippet of military march-esque music that often plays during his scenes.
Light Is Good: In Fast Forward where he's become good, his suit is white.
The Men in Black: Clearly meant to invoke this motif with his sunglasses, black suit, and tie look. (Though with a Badass Longcoat for some variety.) He's also a government agent investigating aliens, mutants, and other paranormal activities.
My God, What Have I Done?: When he learns that the mutagen he created his fake aliens with caused an outbreak of mutations in New York, he is horrified that his actions created such a danger to the world.
A Nazi by Any Other Name: Leads an army of faceless mooks, dreams of using his experiments to create in his own words a "genetically perfect race," and is shown to be perfectly okay with exterminating half the world's population if it came down to it when Splinter calls him out.
One-Man Army: He can hold his own against all four of the Turtles, AND Karai and Hun all at the same time. He's also seen effortlessly fending off the Foot Elite in "Exodus".
Out of Focus: In Season 5, he only appears in one episode outside of the season finale due to the focus being outside of New York for half the season. He gets Demoted to Extra in Season 7 when he only makes a single cameo in the closing moments of the series finale.
Promotion to Opening Titles: From the fourth season to the sixth season.
Playing with Syringes: He tends to break out strings for research such as to take mutant DNA.
Powered Armor: Starts using a suit in Season 4.
Rank Scales with Asskicking: Leads a government agency and is by far the best soldier in it. Exaggerated in "Fast Forward" when he's president of Earth.
Really 700 Years Old: He's somewhere around 220.
Sinister Shades: In his usual attire, battle outfit, and in Fast Forward.
Super-Soldier: Thanks to the genetic research that was done on him by aliens, and altering his DNA to prolong his life.
Supporting Leader: When the Turtles and Karai are fighting the Demon Shredder, Bishop takes command of the Purple Dragons AND the Justice Force along with his own men.
Touched by Vorlons: Got a stronger body and much longer life thanks to aliens experimenting on him, though he wasn't happy with the latter part.
Tragic Bigot: Downplayed due to his actions. He was a colonial soldier who ended up being experimented on by aliens, which gave him an everlasting hatred of anything inhuman.
Unwitting Pawn: In "Good Genes", he is promised an alien artifact of great power by an unknown entity, and has the Turtles retrieve it for him. When he gets it, he ends up destroying it, which frees the Foot Mystics from Karai's control, leading to the return of the Demon Shredder.
Universally Beloved Leader: In the Future after his Heel–Face Turn, Bishop had founded the Pan Galactic Alliance, and making his goal to help other alien civilizations, he became the respected and beloved President of Earth.
Villain with Good Publicity: Downplayed. He's a very secretive government agent and very few people know of his actual existence. However, he has the backing of the United States government and by the fourth season, the unconditional support of the President himself, which makes him arguably as big of a threat to the Turtles as the Foot Clan, if not moreso. He becomes yet another downplayed example by the time of Fast Forward because by that time, everyone knows of his existence and he's extremely well liked by almost everybody on Earth... but by that time, he's pulled a Heel–Face Turn and is no longer an actual villain.
Well-Intentioned Extremist: In the present, he has one mission: to protect Earth from an alien invasion. As shown during the Triceraton invasion, aliens have shown that they can be a threat to Earth. Emphasise on CAN, however, as they are others who are peaceful. In order to achieve his mission, however, he has used other aliens and even one of his only friends, whose wedding he attended as the best man, as unwilling test subjects for genetic experiments, faked an alien invasion and kidnapped the President in a ploy to guarantee funding for his agency the Earth Protection Force, attempted to produce a sleeper army of Super Soldiers to covertly kill people suspected of being aliens, and ironically prolonged the Triceraton invasion in order to fulfill the terms of an agreement with the Federation.
You Fool!: Delivers one to the Turtles in "Alien Among Us" when they broke off the dish he used to project a fleet of fake flying saucers, explaining the ship he used to abduct the President was remote controlled and they destroyed the remote.

Hamato Yoshi

Yoshi, moments before his demise

Voiced by: Eric Stuart

Yoshi: He, who lives without honor, will end without honor.

A master of ninjutsu and Splinter's former owner.

A Day in the Limelight: "A Tale of Master Yoshi" focuses on him.
Adaptation Relationship Overhaul: In the original comics and most Truer to the Text adaptations, he is killed by Oroku Saki and in the comics, Yoshi only personally knew Saki's older brother Oroku Nagi. Here, the real Oroku Saki existed centuries before and hence has no idea who Yoshi is and it is Yoshi (as a mystical spirit warrior) who kills Saki.
Always Someone Better: Even as children, Yoshi always outdid Mashimi.
Ancient Tradition: He began to train and eventually became a Guardian after meeting Mortu and finding his secret.
Big Damn Heroes: He manifests as a spirit in the Season Five finale to save Splinter from the Tengu Shredder.
Big "NO!": After discovering that Tang Shen has been killed.
Childhood Friend Romance: He met Tang Shen when he was adopted by the Ancient One and fell in love in their later years.
Defiant to the End: In "The Shredder Strikes, Part 1", Splinter tells the Turtles how Yoshi was ambushed by the Shredder's men. He was unarmed, and outnumbered by more than ten to one, but he still wouldn't go down without a fight. And even though he did go down, he was willing to die before he told the Shredder anything, and his last words to the villain were to insult him, saying, "He who lives without honor will end without honor."
Finishing Move: In the finale of Season 5, Yoshi manifests as a spirit and slices the Tengu Shredder in half, finishing him once and for all.
Gladiator Games: It's revealed in flashbacks from "Battle Nexus" that he participated in the tournament. After his death, he was replaced by Splinter.
Scream Discretion Shot: In a flashback from "The Shredder Strikes, Part 1", he gets electrocuted by Hun. We see his silhouette as he's screaming.
Red Oni, Blue Oni: He is the Blue Oni, while Mashimi is the Red Oni.
Roaring Rampage of Revenge: After discovering Tang Shen has been killed, he travels to the Foot's headquarters in search for Mashimi, while fighting any Foot who's in his way.
Plot-Triggering Death: It is his death that led to Splinter meeting the turtles that would become his sons and mutating, and eventually their family's series-wide conflict with the Foot. In Season Five, the Ninja Tribunal even admit this is the real reason why they did not aid Yoshi in fighting against the Utrom Shredder — Yoshi had to die in order to ensure Splinter and the turtles would exist, and eventually help defeat the Tengu Shredder. From their tone of voice, they didn't like the decision any more than Splinter did, even if it was necessary.
Posthumous Character: He was killed before the events of the show by the Shredder.
Pre-Mortem One-Liner: To the Tengu Shredder before he kills him.
Hamato Yoshi: This, demon, IS your very last breath!
Truer to the Text: As of this writing, he's the only incarnation of Hamato Yoshi in television animation to be a separate character from Splinter who owned him as a pet, and was killed off prior to Splinter becoming a mutant, rather than one and the same as Splinter.
We Used to Be Friends: As kids, Yoshi and Mashimi were like brothers. However, Mashimi over time became jealous of him, leading to him joining the Foot Clan.
Whole Costume Reference: He wears Bruce Lee's yellow jumpsuit when fighting his way through the Foot clan's citadel. He also wears Lee's black Tangzhuang suit, despite being Japanese.

The Mayor of New York City

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2022_01_29_100121.png

Voiced by: Uncredited actor

The well-meaning, but easily-misled mayor of NYC.

Corrupt Politician: He seems like a nice person but accepts bribe from both Ch'rell and Karai shamelessly.
Horrible Judge of Character: Shredder and Karai play him like a fiddle to further their plans to cement power and steal alien technology left over from the Triceration Invasion, while he's convinced that they are kind-hearted philanthropists. His suspicions are occasionally aroused, but are always quickly banished due to a Seamless Spontaneous Lie or a large donation toward the city's disaster relief efforts.
Mayor Pain: He casually keeps accepting bribe from the Foot in almost his every appearance.
Nice Guy: Horrible Judge of Character moments aside, he's very polite and considerate.

The U.S. President

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2022_01_29_100027.png

Voiced by: Uncredited actor

The president of America, and Bishop's unenthusiastic superior.

No Party Given: Whenever he's onscreen, there is nothing to indicate his political leaning.
Reasonable Authority Figure: He picks up on the pattern of Bishop being ineffective or too gung-ho and threatens to shut down the EPF if Bishop doesn't fix his behavior. He only changes his mind when some Engineered Heroics make the EPF look like a useful and necessary organization.
Small Role, Big Impact: He only appears in a couple of episodes, but he has the power to shut down the EPF if he chooses, and Bishop's attempts to prevent this cause the S-Gray outbreak that influences the second half of season 4 and season 5.

Dr. Richards

Dr. Marion Richards

Voiced by: Veronica Taylor

The scientist who created Nano.

Smart People Wear Glasses: She's a bespectacled woman involved in ground-breaking science.
The Spock: She is a serious woman who views her invention displaying emotions and personality as an unwanted flaw.

Yukio Mashimi

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2021_03_30_113952.png

Voiced by: Sean Schemmel

Hamato Yoshi's friend and surrogate brother.

Adaptation Relationship Overhaul: He is an expy of Oroku Nagi, Hamato Yoshi's rival and Oroku Saki's older brother. Mashimi is Hamato Yoshi's adoptive brother turned rival, while the Shredder is just his boss.
Dirty Coward: When Yoshi breaks into the Foot's lair to challenge Mashimi to a duel, Mashimi balks at this by standing by and letting the rest of the Foot Ninja do the work for him. However, Shredder will have none of that and orders Mashimi to duel or be killed by him as punishment for the Utroms and Guardians escaping.
Expy: For Oroku Nagi, who was Adapted Out, being the one to compete with Hamato Yoshi for Tang Shen's feelings.
Green-Eyed Monster: Eventually, Tang Shen not requiting his feelings and Hamato Yoshi going onto a promising ordeal resulted in Mashimi murdering Tang Shen, and betraying Yoshi to the Foot Clan.
My God, What Have I Done?: Before he dies, he asks Yoshi to forgive him for all the horrible atrocities he caused.
Mythology Gag: He and Oyuki Mashimi, a character from the Archie comics, share the same last names and their first names are anagrams of each other. This may be a coincidence as his name is probably a reference to a real life person (see No Historical Figures Were Harmed).
No Historical Figures Were Harmed: His name derives from real life historical figure Yukio Mishima, a controversial post-war Japanese right wing nationalist and novelist. Like Mishima, Mashimi is also an important Japanese character in the post-WWII era relative to the 2003 series and while he doesn't commit seppuku, he does have a Small Role, Big Impact on the Turtles' origin story.
Small Role, Big Impact: All his actions, from the betrayal of the Utroms and Yoshi, combined with joining the Foot Clan and the murder of Tang Shen have caused the creation of Splinter and the Turtles as they are today.
You Have Failed Me: Shredder was furious at Yukio when the Utroms and the Guardians escape through pods, something he was unaware of when he was a member. He forced Yukio to face Yoshi alone as a chance to redeem himself.

Tang Shen

Voiced by: Karen Neill

An orphaned girl who was adopted by the Ancient One. She met fellow orphan Hamato Yoshi and they both fell in love.

Adoring the Pests: She found Splinter when he was still a wild rat and stopped Mashimi from killing him, choosing to instead feed him and make him her pet.
Childhood Friend Romance: She met Hamato Yoshi when he was adopted by the Ancient One. Later, they would fall in love.
Flower Motifs: She's associated with cosmos flowers. She holds one in her introduction, a few are seen on the ground near her hand after she dies, and they grow on her grave afterwards.
Friend to All Living Things: When she sees a hungry rat in the kitchen, she adopts him as a pet. Yoshi would later name him Splinter.
Small Role, Big Impact: She's a Posthumous Character who only appears in flashbacks, but her adoption of Splinter was what led to him becoming Yoshi's pet and the eventual mentor to the turtles.
Sound-Only Death: When she's killed by Mashimi, we can only hear her scream.
Yamato Nadeshiko: She's a beautiful and gentle Japanese woman.

Tyler

Voiced by: Tara Jayne

Tyler: Don't call me "kid".

A small kid whose mother gets kidnapped by the Mafia. While being chased by them, he encounters Raphael, who helps him.

The Determinator: He's very determined to save his mother, with or without Raph's help.
Insistent Terminology: He gets quite angry when Raphael calls him "kid".
Too Much A Like: Initially Tyler and Raphael don't get on very good terms, because both are hotheads. Subverted however, when they have to work together in order to save Tyler's mom and by the end of the episode, they do get on good terms.
Your Other Left: While Raphael gets temporarily blinded, Tyler has to give him directions. As you can imagine, this happens.

The Caretaker

^{Click to see him in his youth(SPOILERS)}

The Caretaker: I gave him the same warning I give them all, but he ignored me.

The caretaker of Volpehart Manor, who claims to be under the influence of the Necro Creature.

And I Must Scream: Basically what C.F. Volpehart's life became. He eventually reformed and wanted to kill the monster, but he had spent too long under its grasp, so he was helpless to act. Being immortal, this suffering persisted until the Turtles won.
Deal with the Devil: How his supposed ancestor, C.F. Volpehart, gained his wealth.
Generation Xerox: He claims that he is a descendant of C.F. Volpehart. Both him and Volpehart are under the influence of the Necro Creature. Justified, since they are one and the same.
Ignored Expert: The caretaker constantly warns people to stay away from Volpehart manor and not to search for more of the coins of the Necro Creature, but they never listen to him.
No Immortal Inertia: After the Necro Creature is defeated, he's released from its grasp, reveals to Angel that he is C.F. Volpehart and collapses into dust.
Really 700 Years Old: The caretaker is revealed to be C.F. Volpehart, given immortality from the monster a thousand years ago.
Significant Anagram: C.F. Volpehart/ H. P. Lovecraft.
Unfazed Everyman: Donatello is surprised that he isn't shocked to see four mutated turtles with ninja weapons. The caretaker explains:
The Caretaker: I have seen many strange things in my life. Very little surprises me.
Walking Spoiler: There's a reason why most of his folder is filled with spoilers.

T9581

https://static.tvtropes.org/pmwiki/pub/images/t985.png

"T9581" was accidentally released by the Purple Dragons after they steal several crates from Bishop. While it may appear as a simple rampaging monster, there's more to it than meets the eye.

Alien Blood: After the creature gets ripped apart by Hun's laser machine gun, he bleeds green blood.
Body Horror: He has several extra limbs, extra eyes, is ripped apart in two and heals himself.
Dark Is Not Evil: He looks monstrous, but he isn't evil.
Extra Eyes: The creature has five eyes.
Harmless Freezing: In the container, from which the Purple Dragons freed him, he was frozen, but quickly overpowers Hun of all people when he is freed.
Healing Factor: In one of the most gruesome scenes from the episode he appears in, he gets ripped apart in two by Hun's laser machinegun and retreats. The creature nearly dies, until he remembers his past life, after which he reattaches both of his halves with tentacles.
It Can Think: Bishop, when tracking the creature, notes how he remembers his past life before he was presumably mutated by him.
The Juggernaut: After he's freed, the creature quickly overpowers Hun, who fights back.
Mix-and-Match Critters: He has the legs of a spider, two different arms and a human head.
Not Quite Dead: At the end of "Dragon's Brew", the creature is engulfed in a large explosion with everybody thinking he has been killed, but the ending shows that he has survived.
Only Known by Their Nickname: The container, from which the creature was freed, had "T9581" written on it. It's later revealed that this was his designation when he was serving in the Navy. The closest we get to knowing his full name is "J.Finn", which was written on his dogtags.
Small Role, Big Impact: Despite one appearing in episode, his escape forced Bishop to create a fake alien invasion in a desperate attempt to save his operations from being shutdown by the President, thus causing the mutant outbreak in New York City afterwards, and setting the return for the Tengu Shredder in the process.
Tragic Monster: Probably the most tragic example of the whole series. He was once a man, J. Finn, who was living the best time of his life: he was a Navy officer, married the woman he loved and even had a child with her. Unfortunately, things go very downhill from here. It's implied that before his child was born, he was captured then mutated by Bishop, turning him into the monster he currently is. And the worst of all, he knows it. It seems that there's no way for him to turn back into a human and is forced to live the rest of his life in this monstrous form, knowing full well that he would never meet his wife and child ever again.
What Happened to the Mouse?: The creature certainly survived the battle from "Dragon's Brew", but he doesn't return.

The Ultimate Gamer

Voiced by: Carrie Keranen (player) and Sean Schemmel (avatar)

An MPORG player who clashes with the Turtles while they are recovering lost databits in cyberspace, late in season 7.

Anti-Villain: The Ultimate Gamer is arrogant, ruthless to her video game opponents, endangers the Turtles, and hates to lose, but as far as she knows, it's just a videogame and not an actual matter of life and death.
Asian and Nerdy: The player behind the ultimate gamer is a young Asian girl who is exremely talented at video games and has thick spectacles and braces.
The Dreaded: Players of the SuperQuest video game are terrified of having to fight the Ultimate Gamer.
Gamer Chick: She is a preteen girl who devotes her time to videogames.
Samus Is a Girl: She uses imposing male personas in the game but is a young girl in real life.

Sarge and Frank

https://static.tvtropes.org/pmwiki/pub/images/screenshot_2021_12_30_093758.png

Voiced By: Ted Lewis and Brian Mallard (Sarge), and Pete Capella (Frank)

Two beat cops who repeatedly come across the aftermaths of the Turtles' adventures.

Comic-Book Fantasy Casting: They resemble the writers of the original comic, Kevin Eastman and Peter Laird.
No Name Given: Neither cop is ever named onscreen, and Frank's name only comes from a Schrödinger's Canon comic.
Old Cop, Young Cop: Sarge has gray hair, while Frank is referred to as "rookie" in the pilot. Sarge also seems to have more of a Weirdness Censor than his partner.
Police Are Useless: They aren't incompetent, but in a city full of mutants, aliens, and masked superheroes, the two cops rarely get to do anything useful besides arresting crooks who have already been incapacitated or distracted.
