Main characters

Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles are a team of anthropomorphic mutant red-eared slider turtles who were 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

  • Voice actor: Jason Biggs (Season 1–2), Dominic Catrambone (Remainder of Season 2), Seth Green (Season 3–5)

Leonardo (nickname Leo) is an enthusiastic ninjutsu student, wears a royal blue mask, and fights with two long swords called Niten Ryu. The oldest and most mature of the four, 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 as sensei, which adds 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

Donatello (nickname Donnie or "Don") is the middle child and third brother of the family. 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.

Raphael

Raphael (nickname Raph) is the second oldest of the turtles. He wears a red mask and fights with two sai. Known for his rage, he commonly takes it out on Mikey, and on occasions Leo, due to their feud. Raphael sports a chip at the top of his shell as a result of Splinter's earlier encounters with the Kraang that were after him.

Michelangelo

Michelangelo (nickname Mikey) is the baby 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 the least mature turtle out of the four. He has an active imagination and he names all the mutated villains.

Allies

Splinter

  • Voice actor: Hoon Lee

Hamato Yoshi (also known as Splinter) 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. During a confrontation with the Kraang, Hamato Yoshi was mutated into a mutant brown rat upon coming into contact with a rat prior to the conflict. Since then ever since alluding 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 father-like role as sensei on his behalf.

April O'Neil

The sixteen-year-old daughter of Dr. Kirby O'Neil and the love interest/crush of Donatello. Unlike her previous incarnations, she possesses extraordinary 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 herself 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.

Karai

Hamato Miwa is the only child 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 16 years old. 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. Karai later mutated into a violet-and-white desert horned viper where an extra chemical ingredient enabled her to shift back and forth and assume hybrid forms. She is Leonardo's love interest throughout the series. She is one-eighth Chinese through her maternal great-grandfather.

Casey Jones

Villains and Adversaries

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.

  • Oroku Saki / Shredder / Super Shredder / Undead Shredder (voiced by Kevin Michael Richardson) – The 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 were 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 own 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 own 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.
  • Takeshi / Tiger Claw (voiced by Eric Bauza) – Takeshi was a Japanese boy who was mutated by the Kraang as a child into a 6 1/2 ft. humanoid mutant Bengal tiger called Tiger Claw with razor-sharp fangs and claws, heightened smell, and superhuman strength upon coming in contact with a Bengal tiger. He and his sister Alopex subsequently became circus performers 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 had been planning to have his revenge against his sister for her betrayal as she plans to do the same. He later lost his eye following 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 sliced off by Alopex and was replaced with a cybernetic arm. During the fifth season, Tiger Claw attempted to use Kavaxas to revive the Shredder. But the attempt nearly started an apocalypse and Tiger Claw renounced his vendetta against the turtles.
  • Chris Bradford / Dogpound / Rahzar (voiced by Clancy Brown) – Chris Bradford was a world-famous martial artist who is secretly a prized member of the Foot Clan, armed with a 400-year-old katana and owning a chain of dojos across the country for the purpose of recruiting Foot Soldiers. He mutated into the mutant Akita called Dogpound as a result of being bitten by Shredder's pet Akita Hachinko, hampering most 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-like form and is referred to as Rahzar since. He serves as Michelangelo’s personal rival ever since he pretended to befriend him in order to get info on Shredder. 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.
  • Xever Montes / Fishface (voiced by Christian Lanz) – Xever Montes was a Brazilian street urchin who was left to roam the criminal underworld of São Paulo, eventually being recruited by the Shredder after attempting to steal something belonging to him. He later mutated into the mutant snake-head Fishface after touching a snakehead in a Chinatown marketplace. Following the mutation, he wears a water-breathing rig and mechanical legs developed by Baxter Stockman. He is always paired up with Rahzar despite their rivalry and he serves as Raph’s primary rival on the battle field. He eventually leaves the Foot Clan in season five at the start of Kavaxas' apocalypse plans.
  • Baxter Stockman / Stockman-Fly – (voiced by Phil LaMarr) – Baxter Stockman 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 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 was bedridden in the aftermath of the Triceraton invasion, Stockman oversees Shredder's mutagen intake and created two bug-mutants 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.
  • Ivan Steranko / Rocksteady (voiced by Fred Tatasciore) – Ivan Steranko 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. However, a falling out resulted in Steranko being mutated into a mutant white rhinoceros called Rocksteady upon being pushed into a mutagen vat filled with white rhinoceros DNA. In Season 5, Bebop and Rocksteady decided to be "super heroes" and had moved to a different state.
  • Anton Zeck / Bebop (voiced by J.B. Smoove) – Anton Zeck was a professional thief in a high-tech suit with a purple X-ray visor, and invisibility function and other high-tech gadgets. Hired by Steranko to steal the Kuro Kabuto, Zeck was later mutated into a mutant common warthog called Bebop upon being shoved into a mutagen vat filled with common warthog DNA.
  • Chrome Dome (voiced by Nolan North) – A ninja android in a dark ninja outfit (which resembles Chris Bradford's full ninja outfit) armed with a plasma sword and whip. Chrome Dome was originally built by the Kraang to keep the Foot Clan sufficient with their invasion plan.
  • Hattori Tatsu (voiced by Michael Hagiwara) – A blind swordsman operating in Japan that was taken in by Shredder at a young age and became his right-hand man. Following Super-Shredder's death, Tatsu planned to succeed Shredder by obtaining the Kuro Kabuto and had some competition from Karai, who was once his pupil. As Tiger Claw and Rahzar claim the Kuro Kabuto, Tatsu's soul was drained from his body by Kavaxas.
  • Shredder Mutants – A trio of mutant 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 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 recreated 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.

    • Elite Footbots – The stronger versions of the Footbots that were created in order to strengthen the Foot Clan during its civil war with Karai's faction. They resemble Chrome Dome except for the fact that they wear metal kasas on their heads.
  • 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 found 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 plan to revive the Shredder.

The Kraang

The Kraang are a race of brain-shaped aliens from 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 actually Utroms that are now 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 have not mastered English and communicate in redundant speech. The Kraang also have enemies in the form of the Utroms that 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:

  • Kraang / Kraang Prime (voiced by Roseanne Barr in season 1 and 2, Rachel Butera in season 3) – A 25 ft. brain-shaped alien who is the leader of the Kraang and one of the main antagonists of the series. Originally an 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.

Prior to joining the Kraang willingly and 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, Subprime was last encountered by the Turtles months prior to his demise in "Trans-Dimensional Turtles".

    • Traag – 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 – A 20 ft. blue fire-spewing rock monster from Dimension X with regenerating abilities who resembles Traag (but is pale pink in color) 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.

Alien species

In addition to the Kraang, there are many other alien species throughout the show that are listed in alphabetical order:

Aeons

The Aeons are an ancient alien race of benevolent, ethereal beings that hail from the planet Zalvadal, a world of vast, beautiful gardens and tranquility that contains all of the sacred knowledge in the cosmos. They were the very first extraterrestrials to evolve into higher beings of mighty power. The very source of all their strength is a mighty crystallized artifact called the Sol Star, containing the very essence of power and life itself. 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 on 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. However, they may not have been aware of how the Sol Star fragment was gradually corrupting April to the point of insanity, in addition to further developing and magnifying most of her psionic abilities to tremendous levels.

Among the known Aeons are:

  • The First Seven - The very first Aeons to exist on planet Zalvadal. After one hundred millennia, their physical selves had disintegrated under unexplained circumstances. After which, each of their spirits were placed into the mystical Sol Star to exist for eternity.
    • Za-Naron (voiced by Mae Whitman via speaking through April) – A supremely powerful and dangerous female Aeon whose spirit dwelled within the mystical Sol Star fragment that was worn by April for most of Season 4. After all of April's psionic abilities are immeasurably magnified to uncontrollable levels, it suddenly awakened and released Za-Naron to the point of taking partial or full possession of April's mind and body.

Daagon

The Daagon are a race of aquatic fish-like aliens that reside in the cosmic ocean of Varuna, a liquid nebula over which they rule. They are one of the few aliens that served as the guardians of the Heart of Darkness fragments.

Among the known Daagon are:

  • Hiidrala (voiced by Lucy Lawless) – The queen of the Daagon with tentacled arms and hair. She is the only one to have complete power over the Cthugga.
  • Daagon Soldiers – The foot soldiers of the Daagon Empire. Michelangelo nicknamed them "Merdudes."

Neutrinos

In this show, the Neutrinos are a race of microscopic aliens.

Among the known Neutrinos are:

  • Neutrino Mercenaries (voiced by Clancy Brown) – A trio of Neutrinos who were sent by Bellybomb to infiltrate Mikey's mind for plans for the Heart of Darkness to give to Lord Dregg, but were defeated by the other Turtles after they were sent into Mikey's mind. After returning to the real world, they tried to escape only to be grabbed by Mikey who then squished them with his foot.

Salamandrians

The Salamandrians are a race of humanoid aliens that resemble newts and salamanders. For some unknown reason, the Salamandrians are the enemies of the Triceraton Empire.

Among the known Salamandrians are:

  • K'Vathrak / Newtralizer (voiced by Danny Trejo) – A fire-belly newt-type Salamandrian in a weapon-upgraded suit of high-tech armor with a huge mouth used to eat the Kraang where he was considered dangerous to them.

  • General R'Kavaka (voiced by Nolan North) - A Salamandrian general that Sal Commander and Mona Lisa report to.

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 wiped out the Kraang in the season three final, the Triceratons replace the Foot Clan as one of the main villains in the series. With the exception of 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) – The ruler of the Triceraton Empire, a 250-centimeter (8.2 ft) Triceraton with a more ornate uniform including a cape. Zanmoran is a cruel 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. When the Fugitoid is captured during an effort to rescue them, Zanmoran attempts to force him to repair the Black Hole Generator, but he refuses. The Turtles subsequently escape by briefly taking Zanmoran hostage.
  • Captain Mozar (voiced by Michael Dorn) – The Supreme Commander of the Triceraton army with a broken horn and a prosthetic beak, initially introduced as a captain. He is a 250-centimeter (8.2 ft) Triceraton who is a cunning and brutal military commander. He answers only to the Triceraton Emperor and aims to destroy the enemy at any cost. He debuts in "Annihilation: Earth" Pt. 1 where he leads the Triceraton invasion on Earth to destroy it and thus prevent the Kraang from using it as a new homeworld, and employs the Heart of Darkness previously used by the Kraang to destroy the Triceraton homeworld. However, the Turtles escape Earth's destruction and then travel back in time six months in an effort to prevent this event from happening. They would eventually cross paths with Mozar during their quest where he was promoted to Admiral for successfully retrieving the first piece of the Heart of Darkness. It is later stolen back by the Turtles during their raid on Emperor Zanmoran's ship. Mozar was later demoted back to Captain by the time he attacked the Ulixes in order to reclaim the Heart of Darkness fragment. Despite the fact that the Skeevix Virus launched at the Ulixes was defeated, his soldiers were successful at reclaiming the two fragments of the Heart of Darkness.
  • Sergeant Zog (voiced by Lance Henriksen) – A 260-centimeter (8.5 ft) Triceraton who serves as a scout for the Triceraton army, who is based on Zog from the Mirage Comics. He debuts in "Dinosaur Seen in the Sewers!" where he temporarily befriends Raphael. Due to being poisoned by Earth's atmosphere, he is initially delusional, striking at virtually any being he comes across and rambling on about his mission. After recovering his equipment at the Statue of Liberty, he recognizes Raphael's deception and attacks him before launching a beacon to summon the Triceraton armada to Earth. Left clutching onto a ledge on the Statue of Liberty, Zog refuses Raphael's offer of help and drops from the torch quoting "Long Live the Triceraton Empire."
  • Commander Zoran (voiced by Kevin Michael Richardson) – A commander in the Triceraton army.
  • Commander Zorin – The second-in-command of the Triceraton army who assisted Mozar in the attack on Earth.
  • Sergeant Zark – A sergeant of the Triceraton army who assisted Mozar in the attack on Earth.

Despite commanding a Triceraton garrison, a force of Robot-Raptors, and a Robo-Spinosaurus, she was defeated by the Turtles and their dinosaur allies. Zera is the first known case of a Triceraton female in the series, as all other Triceratons who have appeared onscreen have shared the stereotypical male design.
    • Lieutenant Zorg (voiced by Fred Tatasciore) – An overweight Triceraton who serves under General Zera.
  • Lieutenant Zovox (voiced by Michael Dorn) – A Triceraton that accompanied Captain Mozar to the planet Xaava-Dal.
  • Zarus (voiced by Kevin Michael Richardson) – A Triceraton scientist who accompanied Captain Mozar to the planet Xaava-Dal.
  • Zeno (voiced by John DiMaggio) – A 491-centimeter (16.11 ft) Triceraton warrior who was condemned to the Tri-Arena for not wanting to help Emperor Zanmoran search for the fragments of the Heart of Darkness. Since his imprisonment, he has become a star gladiator; he is thus reminiscent of the 2003 series character Traximus. Zeno fought the Turtles in the arena after giving them advice about their first match, but was later convinced to help them escape due to their shared contempt for the Heart of Darkness/Black Hole Generator.
  • Lieutenant Zax (voiced by Clancy Brown) – A Triceraton who assisted Captain Mozar into reclaiming the two fragments of the Heart of Darkness from the Turtles and later obtaining the final fragment of the Heart of Darkness from the planet Magdomar.

In the course of the series he continually aids the Turtles against the Kraang's plots and even seeks to assist the Earth Protection Force in bolstering their defense arsenal with alien technology, though his good intentions fall apart due to the paranoia of the EPF's leader, General Griffin. He is loosely based on Agent Bishop, a character and antagonist of the Turtles from the 2003 series.
