Allies
Cody Jones
- Voiced by: Christopher C Adams
Casey and April's great-grandson and heir to both O'Neil Tech and the Jones fortune.
- Ascended Fanboy: Grew up reading April and Casey's journals about the turtles. The entire Fast Forward season started because he made a device to watch their adventures through time and accidentally yanked them into the future.
- The Cameo: He briefly appears in the finale, watching the wedding of his great-grandparents through the Time Window.
- Character Development: He grows up, learns to care for himself, and realizes the monster that his uncle is.
- Conveniently an Orphan: Both of his parents are dead and his only relative is his Obviously Evil Uncle.
- Gadgeteer Genius: Invented Time Travel. By accident.
- Interspecies Romance: Clearly wants this with the alien Starlee Hambrath as Playtime's Over revealed, and soon enough it seems they eventually start dating.
- Lonely Rich Kid: The only people in his life before the Turtles and Splinter came to the future were his robot butler and Evil Uncle, so he's thrilled to have his personal heroes crash at his penthouse.
- Non-Idle Rich: To Serling's dismay.
- Put on a Bus: As the Turtles return to the present and with them the setting of the show, Cody is left behind in 2105 and only makes one cameo in the finale after the Season 7 premiere.
- Raised by Robots: Or rather, robot. Since his parents apparently died while he was pretty young, Serling took care of him most of the time. He did have his uncle, but Serling was more of the parental unit in his life.
- Relationship Upgrade: With Starlee as of "Turtle X-Tinction".
- Ship Tease: With Starlee in Playtime's Over.
- Significant Green-Eyed Redhead: Due to the fact he's April and Casey's future great-grandson, he has his great-grandmother’s red hair and green eyes.
- Tagalong Kid: Before he learns to become a competent fighter.
- Teen Genius: An intellect on par with Donnie's.
- Trademark Favorite Food: Serling briefly mentions he has a favorite blueberry something, but doesn't get to elaborate.
Serling
- Voiced by: Marc Thompson
Cody's robotic caretaker, who only barely tolerates the turtles.
- Arm Cannon: As Turtle X Mark II
- Back-to-Back Badasses: With Splinter in Bad Blood.
- Badass Boast: During the Darkest Hour of Dunn's attack in Turtle X-tinction.Serling: It will be a cold day in Hades before I allow you [Cody] to come to harm!
- Battle Butler: He was no slouch in fighting beforehand, but becomes the new Turtle X armor late into the sixth season.
- Berserk Button: Messing with Cody. Dun learned this the hard way.
- Character Development: Eventually stops being so uptight and learns to be more flexible, and forges a strong friendship with the Turtles, and comes to terms with the fact he can't protect Cody from everything.
- Disney Death: See Heroic Sacrifice.
- Fish out of Temporal Water: In the seventh season. He ends up being sent back into the 21st century by Viral, and doesn't entirely enjoy the experience, though
Word of God says he ended up thinking his stay was worth it when he got to witness the wedding of Casey and April. - Heroic Sacrifice: Pulls one in Turtle X-Tinction.
- Mini-Mecha: As Turtle X Mark II
- Odd Friendship: With Splinter, the only member of the 2000's cast who doesn't harass or mock him.
- Robot Butler: He's a fully sentient robot and Cody's primary caregiver.
- Servile Snarker: He's a butler who can snark with the best of them.
- Take a Third Option: Initially he would prefer that Cody never see combat, but after Dunn goes rogue, Serling becomes the Turtle-X Mark II so Cody can still go into battle, but Serling can still protect him as well.
- Transforming Mecha: He can transform into the Turtle X Mark II to serve as Cody's guardian quite literally.
- True Companions: He may dislike the Turtles, but he gets along very well with Master Splinter, and later Donatello.
- Undying Loyalty: To Cody, becoming Turtle X Mark II to better protect him.
- What Happened to the Mouse?: At the end of the series, he's still in the present day, but is nowhere to be seen in Turtles Forever. Presumably he might've been sent back to his own time in the aftermath of April and Casey's wedding but isn't given a single mention as to his whereabouts.
Starlee Hambrath
- Voiced by: Amanda Lipitz
An O'Neil Tech intern and friend of Cody Jones. Both she and Cody seem to have an attraction towards each other.
- All Women Are Lustful: In Playtime's Over, she manages to swindle Cody into a date and is happily attached to his arm, batting her eyes flirtatiously and giggling giddily.
- A Day in the Limelight: Enter the Jammerhead's main subplot revolves around her and her family coming to visit.
- Full-Name Ultimatum: Pulls one on Cody Augustus Jones when pretending to be mad over him ditching her in the mall.
- Interspecies Romance: Clearly wants this with Cody as Playtime's Over revealed, and soon enough it seems they are dating.
- Nice Girl: A sweet girl who's loyal to Cody and the gang.
- O.O.C. Is Serious Business: She's a nice, sweet girl, but her mother irritates her so much she becomes very agitated very quickly.
- Relationship Upgrade: With Cody as of "Turtle X-Tinction".
- Rollerblade Good: Always seen on roller blades.
- Rubber-Forehead Alien: Pointy ears, blue skin, and large eyes differentiate her from standard humans.
- Satellite Character: Averted. Her romance with Cody isn't focused on too much, and we meet her some time before she confesses her feelings, so it doesn't dominate her character.
- Ship Tease: In Playtime's Over, she manages to swindle Cody into a date and is happily attached to his arm, batting her eyes and giggling. Eventually gets a Relationship Upgrade as they're dating by "Turtle X-Tinction".
- Single Woman Seeks Good Man: She was already trying to start dating Cody, but falls for him harder when she sees him run off to save the Turtles.
- Teen Genius: Cody's age and just as smart.
Constable Aloysius Biggles
- Voiced by: Sean Schemmel
A robot who serves as an officer of the New New York Peacekeepers and who keeps running into the turtles.
- British Copper: In intent if not in reality.
- Butt-Monkey: To the point that the main gag of a preview of an episode revolved around his really long fall from a skyscraper, and Michelangelo finally admits at the end of the promo that someone should probably save him. Funnily enough, in the episode proper this is not played for laughs.
- Character Catchphrase: “'Allo 'Allo 'Allo. Wot's all this then?”
- Inspector Javert: Occasionally, most notably in Playtime's Over.
- Ridiculously Human Robot: Despite being presumably programmed for the job, he rather dislikes the paperwork it involves.
Turtle Titan II
Turtle Titan II
- Voiced by: Marc Diraison
A man from the future, who takes on Michelangelo's old super-heroic identity.
- Animal-Themed Superbeing: By virtue of being a human imitating a turtle.
- Broken Pedestal: When he first meets Michelangelo, the time-displaced original Turtle Titan, he's perturbed by how shallow he can be and temporarily abandons the alter ego in response to this, although they later resolve their issues.
- Fire-Forged Friends: Him and Michelangelo become this.
- Identical Grandson: Of Silver Sentry.
- Jetpack: How he flies.
- Legacy Character: A twofer, continuing the legacies of both Michelangelo and Silver Sentry.
- Rebuilt Pedestal: After almost abandoned due to Michelangelo's jealously and pride, the two team up to defeat Triplet Threat, and after Michelangelo learns his successor is the grandson of his idol, he accepts that the legacy of Turtle Titans is in good hands.
Enemies
Darius Dun
- Voiced by: David Zen Mansley
Cody's uncle and legal guardian, he uses his position as the C.E.O. of O'Neil Tech to facilitate various shady dealings.
- Ambiguous Situation: Whether Darius ever really cared for Cody at all at any point is called into question by a video clip of him affectionately scratching a younger Cody's head. While in the present he has no qualms about trying to murder his nephew, the clip raises the question of whether it was always an act, or if he perhaps did care about Cody in the past.
- Ambiguously Related: We never really find out if he's actually related to Casey and April by blood or simply became Cody's uncle by marrying into the O'Neil/Jones family or having a sibling who did so.
- Bad Boss: He's downright abusive to the Dark Turtles, viewing them as savages and often berates them for failing him.
- Berserk Button: Cody says he hates being called "fatty."
- Big Bad Ensemble: With Sh'Okanabo for the Fast Forward. His attempts to supplant O'Neil Tech from Cody is one of the main overarching plots of the season.
- Broken Pedestal: Cody loved his uncle Darius, even if he was willing to disobey him from time to time, and was completely mortified to learn not only that he was evil, but he'd been lying to his and other people's faces for years without remorse.
- Canon Immigrant: He is introduced into the IDW comics, a whopping decade after his debut in Fast Forward.
- Contrasting Sequel Antagonist: To Ch'Rell, aka the Shredder. Whereas Ch'Rell was an alien who took upon the identity of a prominent politician, Darius Dunn is a completely normal human being and the CEO of O'Neil tech, who is largely seen as legitimate. The Turtles also pick up on his true nature quickly, whereas the Shredder almost managed to convince Leonardo he was altruistic when they first met.
- Corrupt Corporate Executive: Runs a weapons cartel under Cody's nose and deals with criminals like Boss Zuko.
- Devil in Plain Sight: Splinter and the Turtles are quick to pick up on his villainous nature, but their warnings keep falling on deaf ears.
- Evil Uncle: Only using his nephew for his own monetary gain.
- Fat Bastard: He's gigantic and obese, likely from a lifetime of nothing but a fat salary and lavish treatment, and is very much a villainous bastard.
- High-Class Glass: Wears a monocle.
- Illegal Guardian: He's Cody's legal guardian, but he's a dangerous criminal.
- Karma Houdini: As a result of Fast Forward not continuing into another season for his storyline to be resolved, Darius Dun ends his run in the series still at-large.
- Knight of Cerebus: By virtue of being Cody's Evil Uncle, he has a far more personal effect on the heroes when he finally does get outed and nearly kills Cody and Serling.
- Manipulative Bastard: As Cody is too young to understand how the company works, he basically can get whatever he wants done if he explains it to Cody in simple terms. He also plays his nephew and the police like a fiddle.
- Motion-Capture Mecha: As of DNA is Thicker than Water, he is able to control his suit without wearing it.
- Obviously Evil: He is giant fat man with a smug attitude.
- Parental Substitute: Is Cody's main figure of authority until he goes rogue.
- Powered Armor: Has a suit of his own that he wears if challenged.
- Pragmatic Villainy: Before he is outed, he does his best to stay in Cody's good graces including bailing Splinter out of jail when he surely wouldn't mind if the dangerous, intelligent master stayed there. After his outing, he at least bothers to feed the Dark Turtles so they don't starve, even though he only offers them paltry meals like a single large steak for them to fight over.
- Regent for Life: Non-monarchy example. Though Cody is the true owner of O'Neil Tech, he's too young to run the company itself so Darius is the CEO. He clearly never intended to let Cody take control of the company himself even when he came of age.
- Seven Deadly Sins:
- Greed: All of his actions are purely to make a profit for himself.
- Wrath: He does not take the loss of the company well and seeks to make Cody suffer for every single moment of his revenge.
- Gluttony: While not actually seen, he's very fat which suggests he eats more than he should.
- Sloth: He's an Orcus on His Throne type who usually lets minions do his dirty work, even after he's exposed and forced out of the company.
- Pride: He has a massive ego which is stoked by easily duping the authorities, his company, and his own nephew for years without consequences.
- Envy: He's implied to resent his nephew for being smart enough to build a functioning time window.
- Lust: He strongly lusts for more money and power than he already has.
- Spell My Name With An S: Sometimes, his name is spelled "Darius Dunn."
- Took a Level in Jerkass: One of Serling's home movies was of him affably ruffling a younger Cody's hair, implying at some point in the past he actually was a good uncle to him.
- Villain Has a Point: While he himself never makes the argument, the episode "Race for Glory!" shows that Cody was obviously too young to run his family's company, meaning Darius or someone else would've had to run it for him until he was old enough to do it himself. It's just a shame about the whole Evil Uncle thing...
- Villain with Good Publicity: He starts out this way at the beginning of his arc. Eventually he is exposed.
- What Happened to the Mouse?: Thanks to the Aborted Arc of the Fast Forward season, his final fate was never revealed.
- You Monster!: Splinter is repulsed by him.Splinter: I have met many monsters in my time, Dunn, but it takes a special breed to direct such bile and hatred against a child!
Sh'Okanabo
- Voiced by: Sean Schemmel
An alien invader who has determined that Earth is the ideal planet for him to spread his gene-seed.
- Back for the Finale: After his own Time Window goes haywire, he disappears until the penultimate (though for all effects the final) episode of Fast Forward.
- Bad Boss: Treats Viral very poorly.
- Big Bad Ensemble: With Darius Dun for Fast Forward. His plans to initiate the Day of Awakening is the other long-running storyline of the season.
- The Dreaded: Sh'Okanabo has amassed a reputation as a space boogeyman, who's shrouded in myth and legend. Only this legend is all too real.
- Enemy Mine: Briefly joins forces with the Turtles to defeat the Shredder and the Foot Clan in Timing is Everything.
- Expy: He shares more than a few similarities to Lord Dregg.
- Evil Versus Oblivion: In Timing is Everything. His and Viral's attempts to use the Time Window technology to warp the Earth through time causes time and space to be torn apart. Since this is counterproductive to his plans to conquer Earth, he assists the Turtles in putting things back together.
- Faux Affably Evil: Puts an air of manners when he is making deals Darius Dun and Torbin Zixx, but when he doesn't need to maintain the façade he is a cruel sadist.
- Galactic Conqueror: He's conquered countless planets before arriving to earth, infesting them with his Kanabo drones.
- Karma Houdini: He tricked Torbin Zixx into smuggling a bomb onto a spacecraft and while Zixx did rat him out to the turtles, who in turn reported it to Bishop, Sh'Okanabo never got in trouble for almost hurting many innocent beings.
- Karma Houdini Warranty: His luck finally runs out Day of Awakening, where he's finally killed by the Turtles.
- Killed Off for Real: Destroyed by a light grenade from Donnie and Raph.
- Knight of Cerebus: Episodes that feature him as the main antagonist are far more serious with larger ramifications.
- Light Is Good/Dark Is Evil: He looks dark and works in the shadows, is never seen walking around in daylight, if weak enough, sunlight can hurt him and he was killed by a solar grenade.
- Spikes of Villainy: Especially in his first form.
- Villain Team-Up: With fellow Big Bad Darius Dun in Bad Blood.
- The Virus: Anyone infected with his gene seeds becomes a Kanabo drone subservient to him.
- Voluntary Shapeshifting: He can change his body at will, spawning tentacles or becoming a large slime monster.
- Weakened by the Light: Kanabo drones suffer from this weakness to Earth's sunlight. Sh'Okanabo is initially immune until the Gene Seeds are damaged, forcing him to flee Earth.
Viral
- Voiced by: Eva Christensen
An A.I. who serves under Sh'Okanabo.
- Cyber Cyclops: In her corporeal form, anyway.
- Death of Personality: At the beginning of the seventh season, she happens upon a digital copy of Ch'rell's memory which forcefully takes her over, completely purging Viral's essence while reformatting and commandeering her body. So effectively for the rest of the final season, Cyber-Shredder is the one inhabiting what remains of her body (while giving it a new upgrade) while Viral's personality is dead and gone.
- The Dragon: Was Sh'Okanabo's lieutenant during his arc.
- Dragon Their Feet/Dragon Ascendant: She returned to menace the Turtles again in the first episode of the Back to the Sewer season, then was assimilated by a digital copy of Ch'rell's memory, which used her data and became the Cyber-Shredder, who was the Big Bad of that season.
- Digitized Hacker: Her greatest strength.
- Fish out of Temporal Water: She gets stuck in the twenty-first century at the beginning of season 7.
- Shapeshifter Weapon: Her corporeal form is based on a shape-shifting training bot, whose limbs can turn into things like chainsaws.
- Smurfette Principle: She is the sole female (or at least referred to as female) villain in the whole Fast Forward season. In fact, she and Starlee are the only females of note in the season.
- Underestimating Badassery: Viral is quite bad in gauging her opponents' competence. During her first encounter, she trapped the Ninja Turtles (sans Don) in level 2 of a training simulation program and is caught completely off guard when the Turtles successfully defeat their opponents and sit around waiting for her. This is also what ultimately causes her downfall as she dismisses the Cyber Shredder's data vault as a "rudimentary piece of tech", despite it being clearly strong enough to keep her out. This directly leads to her death.
Jammerhead
- Voiced by: Tom Wayland
A cyborg who runs the Street Phantoms, a New York gang.
- Canon Immigrant: He is later introduced in the IDW comic series about a decade after Fast Forward.
- Compressed Hair: His hair is completely obscured by his hood despite the fact that it's several feet high.
- Contrasting Sequel Antagonist: To Hun, being the leader of a New York gang, but unlike Hun, a surprisingly intelligent bruiser and martial artist who will often try and ignore the Turtles unless they get involved, Jammerhead is skinny and reliant on his augmentations to fight, often acting impulsively, such as prioritizing getting rid of the Turtles whenever the opportunity arises.
- Cyborg: Allows him to add new technology to upgrade himself.
- Intangible Man: Like all members of the Street Phantoms, thanks to their phasing technology.
- It's Personal: He develops a personal hatred of the Turtles after they first cross paths. In following appearances, he eagerly tries to settle up with them whenever possible.
- Not-So-Harmless Villain: He's the Starter Villain to the Turtles in the sixth season and isn't the toughest villain all around in various appearances. However, in "Enter The Jammerhead", he ends up being able to thrash the Turtles and Splinter because he downloaded the skills of various martial arts masters into his system.
- Slasher Smile: His default expression.
- Smarter Than You Look: He looks like a wimpy little imp, but he's a genius who's got enough skills to poise a serious threat to the Turtles. He's constantly upgrading not only his tech, but himself as well.
- Smug Snake: Is a small time criminal with a massive ego.
- Starter Villain: He is the first villain of the Fast Forward season that the Turtles face, and is taken out by them. He later reappears in three more episodes.
- Took a Level in Badass: In "Enter The Jammerhead" he downloads multiple martial arts into his system and becomes a considerably more difficult opponent than usual for the Turtles and Splinter.
The Inuwashi Gunjin
A quartet of winged humanoids who serve as Darius Dun's reluctant enforcers.
- Anti-Villains: They work for Darius Dun only because they have been implanted with electronic machines that Dun uses to torture and contain them. They kidnap Cody and threaten to kill him if Dun (who needs Cody alive) won't free them. They note the turtles' honor for repeatedly saving Cody who's little help to them (at the time). They finally decide to follow the turtles' example of honorability and give them time to escape from drowning.
- Forced into Evil: They aren't bad guys, they are just forced to work for a bad guy.
- Heel–Face Turn: They all pull one once they are finally freed from Dun's control.
- Last of Their Kind: Due to the wars they fought in ending, they are considered obsolete.
- Mirroring Factions: To the Turtles, being a quartet of Color-Coded Characters that value honor and are the only ones of their kind.
- Proud Warrior Race Guys: Their race was once the most feared force of earth and sky.
- The Voiceless: The leader and the red member are the only ones to ever speak. The other two only make grunts or remain silent.
- Winged Humanoid: Very large ones.
- Worthy Opponent: As they witness the turtles saving multiple times Cody who's not much of a help in a fight, they remark that to be truly honorable.
The Dark Turtles
- Voiced by: Michael Sinterniklaas (Dark Leo), Frank Frankson (Dark Raph), Sam Riegel (Dark Don) and Wayne Grayson (Dark Mikey)
Created by Sh'Okanabo from the turtles' genetic material, these four mutant turtles serve Darius Dun. They are all voiced by the same actors for the original turtles.
- All There in the Script: In the show proper, they're only referred to as the turtles' clones. Even among themselves, they only call each other insults or mocking nicknames. It seems to be understood within the series that they use the same names as their clones, but only Dark Leo is ever referred to as "Dark Leo" by Don and that's because the original Leo is in the room. The other three are never referred to as such. But the credits and other materials call them the "Dark Turtles."
- Averted in the episode DNA is Thicker than Water, where Dark Raph refers to himself and his brother as Dark Turtles ("Every dark turtle for himself!")
- Ax-Crazy: All of them, but Dark Mikey especially has a few screws loose and is the most violent.
- Becoming the Mask: In "DNA is Thicker Than Water", Dark Leo initially only saves Cody to infiltrate his penthouse, but the end of the episode suggests that the time he spent with the Turtles may genuinely have set him down a path toward being better, as he divides the steak among his brothers while not taking any for himself rather than trying to hoard it.
- Big Brother Instinct: Dark Leo's time with the turtles rubs off on him towards the end of DNA Is Thicker Than Water, where he divides up the meat among his brothers. This action is so unexpected that it sparks confusion among them.
- Inverted with Dark Don, who rescues Dark Leo at the end of their first appearance.
- Big Little Brother: Dark Leo is the oldest brother, but he's the shortest amongst his brothers (at least going by their official heights, in their first appearance, he appears to be slightly taller than Dark Mike) while Dark Don, who is either the second youngest one or the second oldest (According to Kevin Eastman, Don is older than Raph) is tallest among the Turtle clones.
- Color-Coded Characters: The color of each turtles' skin more or less corresponds to their counterparts' bandanna colors, though Dark Mikey is more yellow with orange eyes.
- Dark Is Evil: At first. They were more than eager to try destroying their original counterparts.
- Dark Is Not Evil: They have the capacity to be better if they were given the chance.
- The Dragon: They serve as Dun's henchmen from their debut episode onward, but Dark Leo is the best candidate.
- Dumb Muscle: Dark Raph. He was so stupid that he couldn't pick up Mikey's sarcasm.
- Evil Twins: The reflections of the four main heroes.
- Forced into Evil: While it doesn't occur in the same way as with their predecessors, the Gunjin, the episode DNA is Thicker Than Water implies they have the capacity to be better turtles if it weren't for Dun.
- Geek Physiques: Dark Don is the tallest and skinniest of the quartet.
- Hidden Depths: If you watched closely, you'll notice several interesting behaviors for the dark turtles that conflict with their normal, boorish demeanor.
- In one scene during DNA Is Thicker Than Water, Dark Leo is shown to stand in attention to Dunn — while the others stand casually — and seems genuinely upset about failing him. He, like original Leo, seems to bear the most responsibility of the four and, perhaps, wishes for the approval of his authority figure. That's not to mention his Character Development through the whole episode.
- Dark Raph takes Mikey's comment about his appearance rather hard and Dark Mikey evens says that he's become sensitive about his looks. Considering how happy he was when he thought Mikey called him better looking than original Raph, it seems Dark Raph wants to feel handsome and have someone accept him.
- I'm a Humanitarian:Dark Raph: Let's crack your shell open and see if there's a yummy cream filling inside!
- Laughing Mad: All of them, primarily Dark Mikey.
- Oddball Doppelgangers: The turtles aren't very normal themselves, but their clones are... something else. Lampshaded by Dark Mikey.Dark Mikey: Clones from your tissue, but with lots and lots of issues!
- Off with His Head!: In their first two appearances, Dark Leo threatened to cut off someone's head.Dark Leo: (holding his sword next to Cody's neck) No sudden moves, or your friend here loses his head.Leonardo: How long have you been working for Dun?Dark Leo: Details, details. You should be paying attention to more immediate matters, like keeping your head on!
- Prehensile Tail: Dark Don is the only member with a tail. He uses it mostly for combat, but he has grabbed things with it.
- Psycho Rangers: Clones of the turtles who all have their own personality quirks.
- Reptiles Are Abhorrent: Unlike the main heroic turtles.
- Slasher Smile / Psychotic Smirk: They at least show off one.
Torbin Zixx
- Voiced by: David Elliot
A famed mercenary who has several run-ins with the turtles.
- Advertised Extra: Downplayed. He appears alongside Bishop in the opening credits, implying an important role in the series but makes only three appearances altogether. In reality, he shows up about as many times as the Inuwashi Gunjin, the Dark Turtles, and Triple Threat, with his importance in the series being no greater or lesser than theirs.
- Ambiguously Human: The basic outline of his body looks human but he doesn't have an Earth-based name and it's uncertain if he has more alien features underneath his mask. It's ultimately unclear if he's a human from Earth who became an intergalactic mercenary that took on a more exotic name for "space cred" or he's one of those Human Aliens like what you'd find in the Federation.
- Break the Haughty: For all his smug, condescending attitude towards everyone, he finally loses his composure in Zixxth Sense when Donatello turns the tables on him and leaves him to deal with an angry crime lord looking to settle a debt with him.
- Characterization Marches On: When he made his first appearance, he was an unscrupulous mercenary but towards the end, he showed that he did have some standards by not wanting to help Sh'Okanabo kill a lot of innocent people, hinting that he could've eventually pulled a Heel–Face Turn and become something akin to a Lovable Rogue ally to the Turtles. However, in his subsequent appearances, his morality is played down and he's simply presented as a cheap swindler the Turtles continue to have an antagonistic and difficult relationship with.
- Combat Pragmatist: He's an extremely dirty fighter.
- Consummate Liar: He alternates between lying and telling the truth, so one can never tell when he's being honest.
- Con Man: Almost every time he goes up against the Turtles, he swindles them.
- Deconstructed Character Archetype: Of the Han Solo-esque Lovable Rogue variety. He's a cynical, snarky mercenary who butts heads with the heroes and has a single moment where he shows himself to have a Hidden Heart of Gold when he reveals he's against Sh'Okanabo's plan to kill innocent people and helps to save the Turtles. Beyond that, despite teaming up with the Turtles in subsequent appearances, he doesn't display any further character development to become a better person and remains an overall selfish Jerkass and a shameless Con Man who swindles the Turtles and everyone else without remorse. And rather than making a full Heel–Face Turn and joining the Turtles to help defeat a Big Bad like Sh'Okanabo, he ends his run in the series being caught in a situation where Karma Houdini Warranty finally catches up to him and he receives a fate more befitting of a Saturday-Morning Cartoon villain than anything else.
- Even Evil Has Standards: Deliver/smuggle an illegal package for an alien? Sure. Said package turns out to be a bomb that could've potentially hurt many innocent humans and aliens? Yeah, big mistake. And for all his bad qualities, he doesn't seem to be too keen on actually allowing the Turtles to die or rot in prison, as shown when he saved them in his first appearance and by the time of his final appearance, at which point the Turtles were at their wits end with his swindling ways, at least has the decency to bust them out of Boss Zukko's prison.
- Hated by All: Zixx's constant double dealing and lies have made him numerous enemies and left in debt to various criminals. Boss Zukko reveals that Zixx has quite a few bounties on head but decides to keep Zixx for himself to make him suffer.
- Heroic Sacrifice: Volunteers to make one in the final episode of Fast Forward to save Earth from a dark matter asteroid. It's actually his ship, which he escaped to with a device that had been jury-rigged to destroy the asteroid.
- Karma Houdini Warranty: In his first two appearances, he was always able to either escape capture or swindle the Turtles. However, in his final appearance during Zixxth Sense, the Turtles are able to finally turn the tables on him and switch the transmitter Zixx was trying to steal with a coffee machine. And once Zixx fails to deliver the transmitter to the alien crime lord he was working for, he found himself in some rather precarious crosshairs as the alien crime boss decided he had enough of Zixx and turned on him violently.
- Post-Final Boss: He's essentially this for the sixth season. Sh'Okanabo is the climactic Big Bad the Turtles had to fight and defeat in the second-to-last episode of the season while Zixx is the final Fast Forward rogue they confront. Ultimately, Zixx's story is wrapped up without the Turtles even having to fight him in a spectacular battle but instead, tricking him and getting him into serious trouble with an alien crime boss to completely wrap up Fast Forward.
- Small Role, Big Impact: He only has three major appearances, but the first one results in Sh'Okanabo getting his ship past Earth's defense grid and being able to set up shop beneath New York.
- Smug Snake: He speaks to the Turtles and many of his alien criminal associates alike with the same smug, condescending tone of voice. Eventually, his overconfidence leads to him paying the price big time when Donatello switched his transmitter with a coffee machine and ensured Zixx had to deal with a crime boss who wouldn't put up with his nonsense anymore.
- Wild Card: Is an unpredictable mercenary who will do whatever it is benefits him. This has involved helping the Turtles as well scamming them.
Triple Threat
Green: "Hey sports fans, I'm back!"
Red: "And I wanna put the hurt on someone!"
Yellow: [laughing] "Hurt, dirt, shirt, giraffe!"
— Headlock Prime
A pro-wrestler turned criminal who sports three heads, each with its own personality.
- Cloud Cuckoo Lander: The yellow-skinned, rightmost head.
- Color-Coded Characters: Each head is colored differently: red for the violent head, blue for the calculating head, and yellow for the clouduckoolander head.
- Cyclops: "Green" is the only uni-eyed head among them.
- Genius Bruiser: The green, middle head is considered the brains of their plans.
- The Giant: Keeping with his wrestling theme, he's the largest known wrestler.
- Multiple Head Case: Triple Threat has three heads sharing one behemoth sized wrestler body.
- Not So Above It All: Despite being considered the rational head out of the three, "Green" does seem to enjoy partaking some mindless fighting if they align with their overall plan.
- Red Is Violent: "Red" tends to be the most gung-ho about charging into a fight, along with instigating new ones.
- Wrestler in All of Us: Considering their pro-wrestling background, a lot of their throws and holds, consist of brutally familiar wrestling maneuvers.
- Wrestling Monster: A more literal example. His debut episode, Headlock Prime, has him hijacking Madison Square Garden's latest wrestling event to take revenge against modern wrestling, adopting his own Heel persona to beat down current wrestlers unequipped to handle unscripted violence.
