Main characters

Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles is a team of anthropomorphic red-eared slider turtle mutants who have been hidden ever since their mutations within the sewers of New York City and usually go up to the surface only in the night time.

* Leonardo (voiced by Jason Biggs in seasons 1 & 2, Dominic Catrambone for the remainder of season 2 and Seth Green in seasons 3–5) is an enthusiastic ninjutsu student, wears a royal blue mask, and fights with two long swords called Katanas. Leo is the oldest and most mature of the turtles and the second oldest of Splinter's children, he is the fearless leader of the Ninja Turtles. In the aftermath of Splinter's passing, he reluctantly stepped up to the increasingly difficult role of sensei, which added even more pressure onto him. Since the episode ''"The Deadly Venom"'', he is the only Ninja Turtle who is capable of using the spiritual, healing abilities of "the healing hands" technique to heal himself and others which enshrouds his body in a white aura by chanting the mantra and the right hand seals.
* Donatello (voiced by Rob Paulsen) is the smartest and second youngest of his four brothers. He is in charge of the design and manufacture of all of the tools and weapons in the Turtles' arsenal. He is also a gifted hacker. He wears a purple mask and fights with a rokushakubo which converts to a naginata via a blade inside one end of the staff. He has a huge crush on April and a rivalry with Casey because of it. Despite his smarts, he can be anxious and can at times get into a rage, but is often the most gentle and ultimately means well. Paulsen had previously voiced Raphael in the 1987 series of the same name.
* Raphael (voiced by Sean Astin) is the strongest, most impulsive and second eldest of his four brothers who serves as the muscle. He wears a red mask and fights with two sai. Known for his rage, he commonly takes it out on his brothers. Raphael sports a crack at the top of his front shell as a result of Splinter's earlier encounters with the Kraang that were after him. Despite his anger issues and rebellious nature, he openly loves his family and allies.
* Michelangelo (voiced by Greg Cipes) is the youngest of the family and is a lover of video games, skateboarding, pranks and pizza. He wears an orange mask and fights with two nunchaku which convert into kusarigama via a blade inside of one of the sticks of each nunchaku and extra lengths of chain stored in the other. He loves to prank Donatello and Raphael the most. It is easy to tell that he is the youngest sibling on account of his most childish behaviors, being an immature turtle out of the four. He has an active imagination and he names all the mutated characters. Despite his immaturity, He is the most optimistic and kindhearted of the brothers, often bringing a lighter mood to the team's adventures.
* Hamato Yoshi / Splinter (voiced by Hoon Lee) is the son and heir of Hamato Yūta, the leader of the Hamato Clan whose rivalry with the Foot Clan came to an end when he was a child, and the adoptive father of the turtles. During a confrontation with the Kraang, Hamato Yoshi was mutated into a mutant brown rat upon coming into contact with a rat before the conflict. Since then ever since alluding to the Kraang, he trained the Turtles in ninjutsu. During the Triceraton invasion, he is killed by Shredder but this attempt is foiled when the turtles travel back in time to save Earth. In the second-to-last episode of Season 4, "Requiem" he is again murdered by Super Shredder and buried at the O'Neil farmhouse. His spirit continues to watch over his family, imparting wisdom and advice to Leonardo, who reluctantly takes on the more challenging fatherlike role of sensei on his behalf.

Allies

* April O'Neil (voiced by Mae Whitman) is the 16-year-old, daughter of Dr. Kirby O'Neil and the love interest/crush of Donatello. Contrary to her previous incarnations, she possesses extraordinarily strong psionic/extrasensory abilities; having been born a human/Kraang mutant hybrid, as a byproduct of her late mother being experimented on by the Kraang before she was born, which she gradually learns to develop further and increase considerably in strength as the show progresses; particularly in Season 4 and Season 5. Her psionic aura varies from being transparent, to white, to yellow. Since "Tale of Tiger Claw" her psychic and extrasensory powers have been greatly reduced, as she no longer can draw more strength from the mystical Sol Star necklace she had destroyed, but they are still far stronger than they were before she acquired the Aeons mystical gift. Her ninja weaponry is a Tessen and, later, a dragon tanto. She proves capable of such compassion for animals and also sees cyborgs as people for their personalities instead of bodies as shown by Professor Honeycutt. Donatello and Casey both have a crush on her and she has shown hints of feeling the same towards them too.
* Hamato Miwa / Karai (voiced by Kelly Hu) was the only 16-year-old human child, until mutated, and willful daughter of Hamato Yoshi (Splinter) and the late Tang Shen, who was taken away from Splinter by Oroku Saki when she was just an infant and renamed Karai. She is the oldest and only biological child of Master Splinter. Initially, she was their sworn enemy, but soon became a trusted ally after learning the truth about her parents and grew even closer to Leonardo, who had liked her since they first met. Karai later mutated into a violet-and-white horned viper where an extra chemical ingredient enabled her to shift back and forth and assume hybrid forms. She had grown to ally herself with her adoptive brothers; the Turtles, her true father; Splinter, April, Casey and their allies. She is one-eighth Chinese through her maternal great-grandfather.
* Casey Jones (voiced by Josh Peck) is the teenage son of a former NHL player at April's school who April is hired to tutor for an extra credit assignment. He later became an ally of the Turtles.

He eventually was again experimented on where he regained his power of speech and gained the strong psionic abilities of telepathy and telekinesis; quite similar to April's. He is the brains of the Mighty Mutanimals. Rockwell emits a light purple psionic aura; whereas April's varies from white, to pale blue, to bright yellow.
* Chompy Picasso (vocal effects provided by Dee Bradley Baker) is an alien turtle and the child of Tokka who has become Raphael's pet turtle since Season 4. Like his mother, Chompy can breathe fire.

Villains

Foot Clan

The Foot Clan is a ninja criminal organization that was founded 1,500 years ago in Japan by a ninja named Koga Takuza when he forged an alloy stronger than steel from the stolen sacred totems of his defeated adversaries to fashion a helmet known as the Kuro Kabuto.

* Shredder (Teenage Mutant Ninja Turtles), Oroku Saki / Shredder (voiced by Kevin Michael Richardson) is the ruthless and vengeful leader of the Foot Clan and one of the two main antagonists of the series. Adopted by the Hamato Clan after the original Foot Clan was defeated, Saki was raised as a brother to Yoshi until spurred by both his unrequited feelings for Tang Shen and learning his true heritage. As a result of an ensuing battle, Shredder was left badly burned and scarred after unintentionally killing Shen, leaving Yoshi to die while stealing away his daughter Miwa to raise as his child. Upon learning of Yoshi's survival, and later his mutation into Splinter, Shredder vowed a vendetta against him and the turtles. This led to his dealings with the Kraang and ultimately placing his want to kill Splinter over his survival. He does succeed in killing Splinter during the Triceraton Invasion, but the Turtles travel back in time to save Earth and warn Splinter, foiling Shredder's attempt and resulting in him being mortally wounded. Shredder had to subject himself to a refined mutagen to heal his wounds while gaining new power. This results in him becoming Super-Shredder who is larger with retractable claws and blades coming out of his back, arms, shoulders, parts of the legs, knees, and feet. He eventually succeeds in killing Splinter a second time by running him through with his mutated arm blades and is ultimately destroyed by Leonardo's katanas. But in season five, Shredder is revived as a zombie by Kavaxas, having lost sense of time while dead and gaining regenerative abilities and telekinesis. While forced to serve Kavaxas, the Zombie Shredder ultimately played a role in Kavaxas' defeat where he dragged him back to the Netherworld.

He and his sister Alopex subsequently became circus performers and then a pair of dangerous assassins, though she later removed his tail in a rage for making her a criminal as well as the fact that their parents were one of his victims. Since then, he has been planning to have his revenge against his sister for her betrayal as she plans to do the same. Later, he lost his left eye after his first engagement with the Turtles and ended up in the 1987 cartoon series dimension, but eventually returned and became Shredder's second-in-command. When Tiger Claw faced off against Alopex again, half of his right arm was severed by her and was replaced with a cybernetic arm. During the fifth season, Tiger Claw attempted to use Kavaxas to revive the Shredder. However, the attempt nearly started an apocalypse and Tiger Claw renounced his vendetta against the turtles.

He mutated into the mutant Akita (dog), Akita called Dogpound as a result of being bitten by Shredder's pet Akita Hachinko, hampering most of his fighting abilities as he attempted to find a means to restore his humanity. But being knocked into a mutagen vat caused Bradford to be mutated further into a near-skeletal werewolf form and is referred to as Rahzar since. He has served as Michelangelo's rival ever since he pretended to befriend him to get info on Splinter. After drowning in the season four finale following his fight with Leatherhead, Rahzar was brought back to life by Kavaxas in the fifth season. During the final fight with Kavaxas, Tiger Claw knocked Rahzar into the abyss leading to the Netherworld.

He eventually leaves the Foot Clan in season five at the start of Kavaxas' apocalypse plans.
* Baxter Stockman (voiced by Phil LaMarr) was a child prodigy who tried proving his brilliance at a science fair at school by presenting a volcano with real lava, which ended up burning down the gym and getting him Expulsion (education), expelled. Baxter was eventually brought into Shredder's services and reversed-engineered much of the Kraangs' technology before he briefly escaped. After being recaptured, Stockman was outfitted with a mutagen collar to hinder any further treachery. But after failing a few more times, the collar is triggered and Stockman is mutated into a mutant housefly while later placed in charge of mutagen experiments. While Shredder is bedridden in the aftermath of the Triceraton invasion, Stockman oversees Shredder's mutagen intake and creates Antrax and Scumbug to assist him in an attempt to replenish the Foot's wealth. He is finally restored to his original human form by Donatello's retro-mutagen during the final battle against Super-Shredder.
* Bebop and Rocksteady, Ivan Steranko / Rocksteady (voiced by Fred Tatasciore) was a Russian arms dealer and artifact collector with a gold tooth and a diamond right eye, who is an old friend and business partner of Shredder.

As Tiger Claw and Rahzar claim the Kuro Kabuto, Tatsu's soul was drained from his body by Kavaxas.
* Shredder Clones, Shredder Mutants is a trio of mutant Cloning, clones created by Stockman-Fly from the DNA of the Shredder and different crustaceans, all three of them based on the Shredder Elite from the Teenage Mutant Ninja Turtles (Mirage Studios), Mirage Comics. They serve as the guards of the Foot Clan's lab. While Mikey fights Stockman-Fly, the others fight the Shredder Mutants. Once Splinter manages to regain his mind, he defeats the Shredder Mutants by kicking them into the giant fan below. In "Meet Mondo Gecko", silhouettes of a second set of Shredder Mutants are seen among the audience during the race. In "Attack of the Mega Shredder!", the Shredder Mutants were re-created and were tricked into the mutagen vat by Bebop and Rocksteady, fusing them into a giant crustacean abomination called the Mega Shredder that went on a rampage in the city before it was destroyed by the Turtle Mech.

* Foot Cultists – As revealed by Fishface, the first Foot Cultist was an unnamed homeless man who mutated upon coming into contact with the Super-Shredder's mutagen blood and captured various people to mutate them into photophobic creatures that wear hooded cloaks. Because of their origins and Shredder-like appearance, the Foot Cultists possess the Shredder's genetic memory and act on it when Tiger Claw finds them. Tiger Claw used the Foot Cultists to obtain the Scroll of the Demodragon and the Seal of the Ancients to control Kavaxas in their plans to revive the Shredder.

The Kraang

The Kraang are a race of brain-shaped aliens from Dimension X (Teenage Mutant Ninja Turtles), Dimension X, piloting robotic bodies called Kraangdroids that are responsible for bringing some mutagen to Earth a thousand years ago. As revealed in "The War for Dimension X", the Kraang are Utroms that are psychically controlled by Kraang Prime resulting in the Kraang Hive Mind. As they became extensions of Kraang Prime's will with trace remnants of individuality, they all address one another as "Kraang", and they have not mastered English and communicate in redundant speech; for example, "Kraang, destroy the ones who call themselves 'the turtles' when that which is the signal is the signal that I give". The Kraang also have enemies in the form of the Utroms whom Kraang Prime could not place under mind control, and the Triceraton Empire for destroying their homeworld. The Kraang appeared to have mostly been destroyed during the events of "Annihilation: Earth!" Among the known Kraang are:
* Krang, Kraang / Kraang Prime (voiced by Roseanne Barr in seasons 1 and 2 and Rachel Butera in season 3) is a 25 ft. brain-shaped alien who is the leader of the Kraang and one of the main antagonists of the series. Originally a Utrom scientist, Kraang discovered a mutagen within the Kraathatrogon worms and used his research to evolve into his current state while using his gained psychic powers to enslave most of his species and rename them after himself. Kraang Prime is later destroyed in the episode of "Annihilation: Earth!" by the Triceratons when they shoot down the Technodrome which sunk beneath the harbor.
* Knight / Kraang Subprime (voiced by Gilbert Gottfried) is an Utrom turncoat with a robotic left eye, a huge scar, a blue tattoo across his right eye, and a robotic claw on his left front tentacle. Serving as the Kraang's master spy, being the only one among them to fully master the human language, Subprime poses as Irma Langinstein (voiced by Kate Micucci) who is April O'Neil's best friend in high school. Before joining the Kraang willingly and being revealed to be Bishop's brother as well as a hero among their kind, Subprime was originally known as Knight. It was also revealed that he is related to the 1980s Krang. While killed in "Annihilation: Earth!" by the Triceratons upon the Technodrome being shot down over the harbor, Subprime was last encountered by the Turtles months before his demise in "Trans-Dimensional Turtles".
* Ms. Campbell (voiced by Cassandra Peterson) is a research scientist from the World Wide Genome Project who takes an interest in April O'Neil and is revealed to be an unpiloted Kraangdroid.
* Kraang Soldiers (both voiced by Nolan North) are the generic foot soldiers of the Kraang. They mostly move around in the Kraangdroid bodies and the "Normans" which they use to blend into human society, yet they still retain their redundant speech patterns.

* Dracodroid is a two-headed cyborg dragon creature created by the Kraang that serves as their mode of transportation.
* Irma-Bots is a bunch of androids that resemble Kraang Subprime's Irma Laginstein disguise that was originally based on the designs by the Utrom Rook.

Dimension X creatures

The Kraang have used various creatures that come from Dimension X to help them in their plots. Among the Dimension X creatures are:
* Rock Soldiers are a duo of nearly identical 20 ft. humanoid rock monsters from Dimension X with regenerating abilities who serve the Kraang as guards.
** Traag is a 20 ft. lava-spewing rock monster from Dimension X with regenerating abilities who is in service to the Kraang. He first appeared in "TCRI", where he was brought by the Kraang through a portal that connected TCRI to Dimension X. He proved to be a challenge to the Turtles, so Leatherhead ended up dragging him through the portal back to Dimension X. In "Showdown", Traag was seen guarding the portal when the Kraang upgraded it with a force field. When the Turtles tried to destroy it, they drew the attention of him and the Kraang, so Leonardo used the laser to disintegrate Traag. In "Into Dimension X", Traag teamed up with Granitor to attack the Turtles near the Kraang's facility in Dimension X. However, they were both defeated by Michelangelo in his "savage" suit when he used his voice to break apart the part of the cliff both rock monsters were on.
** Granitor is a 20 ft. blue fire-spewing rock monster from Dimension X with regenerating abilities who resembles Traag (but is pale pink) and is in service to the Kraang. He first appeared in "Into Dimension X", where he teamed up with Traag to attack the Turtles near the Kraang's facility in Dimension X. However, they were both defeated by Michelangelo in his "savage" suit when he used his voice to break apart the part of the cliff both rock monsters were on.

Triceraton Empire

The Triceraton Empire is an empire that is inhabited by Triceratons, a race of ''Triceratops''-like aliens. Triceratons breathe nitrogen and the oxygen in Earth's atmosphere can lead to delusions. The Triceraton Empire has been at war with the Kraang for millennia, a conflict that has resulted in the destruction of the Triceraton home world through the Heart of Darkness (a black hole generator) and thus left the Triceratons obsessed with annihilating their enemies by any means necessary, such as destroying any planet that the Kraang want to take over. They are also enemies with the Salamandrians. In the first half of the fourth season, having appeared to wipe out the Kraang in the season three final, the Triceratons replaced the Foot Clan as one of the main villains in the series. Except for Captain Mozar, all the Triceratons introduced so far have names that start with Z. Among the known Triceratons are:
* Emperor Zanmoran (voiced by Michael Ironside) is the ruler of the Triceraton Empire, a Triceraton with a more ornate uniform including a cape. Zanmoran is a sadistic ruler, having decreed Earth's destruction due to its Kraang infestation. After the Turtles travel back in time to prevent this, they are captured during their infiltration of the Triceraton Mother Ship, and their efforts impress Zanmoran enough that he orders them to be thrown into the arena.

Once hidden away, the entire world turned pure evil and corrupted the Aeons as well. When April had restored the world to its former state and splendor by placing the mystical Sol Star in its rightful place, the grateful Aeons gladly gave her a small fragment of it, assuring her that it would grant her luck and great power.
