Main characters

Teenage Mutant Ninja Turtles

The Teenage Mutant Ninja Turtles are a team of humanoid 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 / "Leo" (voiced by Jason Biggs in season 1 and most appearances in season 2, Dominic Catrambone in various episodes of season 2, Seth Green in season 3) - Leonardo is an enthusiastic ninjutsu student, wears a blue mask, and fights with two katana swords called Niten Ryu.

• Raphael / "Raph" (voiced by Sean Astin) - Raphael 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.

• Michelangelo / "Mikey" (voiced by Greg Cipes) - Michelangelo is the youngest of the turtles 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.

• Donatello / "Donnie" (voiced by Rob Paulsen) - Donatello 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.

Allies

• Hamato Yoshi / Splinter (voiced by Hoon Lee) - The Turtles' ninjutsu sensei and adoptive father. Hamato Yoshi was the heir of a peaceful and Zen-philosophical ninja clan that had a historical rivalry with the Foot Clan until it came to an end with the Foot's defeat when he was 2 years old, and it was victory that brought into the Hamato family Oroku Saki (Shredder), the Foot Clan's heir, who Yoshi welcomed with a brotherly bond and maintained a peaceful partnership with throghout their ninjutsu training. Despite being raised as brothers, both Saki and Yoshi eventually became rivals due to the love of a young woman named Tang Shen, whose decision to favor Yoshi left the brotherhood with a great strain, and Yoshi and Shen married and had a beautiful baby daughter named Miwa. However, Shen believed that Miwa was unfit within the Hamato Clan and wished that the family would move to a better life in New York City, but Yoshi turned the offer down, telling that he has numerous responsibilities here in Japan, with an aging father to take care of and a clan to remain loyal to. Feeling pity for Shen, Saki persuaded her that that he is willing to do such a favor with the family, frustrating Yoshi and deepening the rivalry even further until Saki discovered his true heritage one night and turned on his former brother until their battle set the Hamato Clan monastery in a blaze that eventually killed Shen, scarred Shredder's head and wiped out the entire Hamato Clan. Blaming Yoshi for his own error, Shredder adopted Miwa and set out to rebuild the Foot Clan into a ninja crime syndicate while leaving Yoshi for dead. Saddened over the loss of his wife and daughter, Yoshi moved alone to New York under the alias of "Splinter". Having just bought the Turtles from a pet store, Splinter was taking them home when he overheard a conversation in a nearby ally between two human-disguised Kraangdroids who tried to kill him for spying on them. He fought back, eventually knocking a canister of mutagen out of their hands and getting covered with the mutagen inside when it smashed, and the Turtle's bowl with it. As the result of stepping on a brown rat while entering the alley, Splinter mutated into a humanoid mutant brown rat while the Turtles mutated into their current mutant forms. Realizing that acceptance in society is no longer an option, Splinter retreated into the sewers, where has since raised and trained the Turtles in ninjutsu and gave them their names from a Renaissance art book that he found in a storm drain.

• April O'Neil (voiced by Mae Whitman) - The Turtles' first human friend and Donatello's love interest and possibly girlfriend, with Kraang-like powers that were the result of various experiments the Kraang made on her mother before she was born to ensure the birth of the perfect human-Kraang mutant. Realizing how special she was, her father Kirby saved the baby April and escaped to New York City until sixteen years later, when the Kraang finally caught up with them and saw their chance to get her, but the Turtles intervened. While the Kraang got away with Kirby, April's aunt took her in, and the Turtles promised to save her father, thus succeeding after several attempts. She was even offered by Splinter to be trained as a kunoichi. This friendship with the Turtles was left in a disappointing strain when her father was accidentally mutated, but after they saved her from the Foot Clan, she eventually mended their relationship by apologizing for her attitude and sealing it with her first kiss for Donatello, who went on to help her discover the truth about her origin and thus retro-mutated her father.

• Casey Jones (voiced by Josh Peck) - The 17-year-old son of a former NHL player at April's school who April is hired to tutor for an extra credit assignment, and eventually became something more than friends, much to Donatello's jealousy. This unfortunately almost put April and Casey in jeopardy when the Turtles saved both humans from Mutagen Man and a squad of Foot-Bots led by Karai and Chrome Dome, so after April met with the Turtles again to owe them her gratitude for their mistake that caused her father's mutation, Casey took up the role of getting rid of all the criminals and troublesome mutants inhabiting the city as an amateur vigilante. He encountered Raphael during a fight with the Purple Dragons and later followed him to the Turtle Lair, where he is introduced by April to the other three Turtles and Splinter. However, he unknowingly led a pair of Foot-Bots to the lair as well, so he and Raphael had no other choice but to set aside their differences and stop them before the lair's location is exposed to the Foot Clan.

• Hamato Miwa / Karai (voiced by Kelly Hu) - Hamato Miwa was the beautiful daughter of Hamato Yoshi (Splinter) and Tang Shen, who was adopted into the Foot Clan by Oroku Saki (Shredder) following his battle with her father that resulted in her mother's death and the scarring of his own face. Shredder has since raised her as his own, telling her that Splinter is responsible for her mother's death. Leonardo immediately saw some good in her when they first met, despite his brother's and Splinter's doubts, and tried to befriend her as his love interest. However, after Splinter found out about Karai's true identity, he first told Leonardo and some time later the other Turtles and April (whose tessen was he originally wanted to give Karai) that Leonardo might be right about the good in her, if she accepts the truth. Leonardo tried several times to tell her the truth, but she dismissed it as a lie. But after eavesdropping on the Turtles' conversation about her, she began to have doubts towards whether or not Shredder is telling the truth. She lied to April that she'll believe she is Splinter's daughter and initially allowed Leonardo to take her to the Turtle lair (to Raphael's dismay) in order to lead Tiger Claw, but soon found out that she really was being told the truth, and began to regret her actions. Karai eventually made up for it by helping the Turtles fight Tiger Claw, but he overpowered her and took her back to Shredder, who responded by imprisoning her until her rescue by the Turtles, who then brought her back to their lair. However, after hearing the story of their rivalry and her mother's death, she returned to face Shredder alone, but got captured again and used as bait for a trap in Stockman-Fly's lab to mutate the Turtles into snakes (reasoning that, as the natural enemy of the rat, the mutated turtle-snakes would then eat Splinter, who would be unable to fight his sons). But Shredder accidentally caused Karai to fall into the mutagen instead, turning her into a mutant white horned viper with two extra heads for hands and a venomous spit that went on a rampage before escaping as she regained control of herself when about to kill Splinter. Although Donatello hoped to create retro-mutagen to cure Karai, it was revealed that she is a special kind of mutant and can almost completely change back to her human self, retaining only her snake eyes and tongue. During the Kraang's invasion on the city, she went to reside in the Coney Island amusement park until the Turtles found her there. However, after a fight over the retro-mutagen meant for Karai, Bebop and Rocksteady finally captured her and brought her back to Shredder, who promised to cure her of her misery. This was a success though when Karai was restored to human form while retaining certain mutant abilities, only to be brainwashed into once again regarding Shredder as her father and serving him.

• Kirby O'Neil (voiced by Keith Silverstein) - The psychologist father of April O'Neil, who meets the Turtles when he and April are captured by the Kraang.

• Timothy / Pulverizer / Mutagen Man (voiced by Roger Craig Smith) - Timothy was an ineffective teenage ice cream truck vendor fights crime as Pulverizer after witnessing the Turtle's first battle with Baxter Stockman. Due to not coming into any contact with any animal, Timothy dissolved into a mutagen-drinking blob called Mutagen Man.

• Jack J. Kurtzman (voiced by Robert Forster) - A private investigator and journalist investigating the disappearance of Kirby O'Neil and other missing scientists.

• Ice Cream Kitty (vocal effects provided by Kevin Eastman) - A stray tabby cat that April finds in an alley and, deciding to find it a home, asks Mikey to raise as his pet. It mutated into Ice Cream Kitty upon eating Neapolitan Ice Cream that was covered in mutagen.

• Mighty Mutanimals - A team of mutant animals brought together by Jack J. Kurtzman to fight the Kraang.
  • Spike / Slash (voiced by Corey Feldman) - Spike was a young box turtle that was flushed into the sewers from his original owner's home and saved from drowning by Raphael, who took him in as his pet. He used to listen to his owners's angry ranting about his troubles with his family and learned ninjutsu by watching Raphael practice it in his room. Although no one knew at the time, Slash even developed a hatred for the other Turtles, thanks to hearing Raphael's angry chants all his life. One night, he drank from a canister of mutagen that spilled in Raphael's room, mutating himself into a 6 ft. humanoid mutant box turtle with a spiked shell, long fingernails for makeshift weapons, heightened smell and superhuman agility. Obtaining a mace, Slash joined the other Turtles on patrol but revealed his true intentions by beating Donatello and Michelangelo, to Raphael's horror. The following murderous spree nearly took Leonardo's life, but after engaging his former owner, he survived the fall off the roof top and fled into the night, though the incident left Raphael with a lasting regret. Slash eventually got captured a few times by the Kraang during several run-ins with them. In the last of these run-ins, he was freed by Newtralizer and allied with him to start a violent but effective crusade against the Kraang. Despite having a dislike for the Turtles, he still shares the same beliefs they were taught regarding protection of the innocent. So, when the amoral Newtralizer to destroy all humans and Kraang, Slash realized the position he put Raphael in and sided with the Turtles and Casey Jones to stop him. He then made amends with them and declines the offer to rejoin their team before departing, saying that he was better operating solo. As soon as the Kraang's invasion started, Raphael began hoping that Slash survived. He eventually did, however, and was later recruited as leader of the Mighty Mutanimals as they worked with the Turtles to take back the city from the Kraang.
  • Leatherhead (voiced by Peter Lurie) - An American alligator that was originally owned by a kind boy until his parents found out and flushed him down their bathroom toilet into the sewer. The Kraang found him, took him back to Dimension X and experimented on him, mutating him into an 8 ft. humanoid mutant alligator with a tough hide, uncontrollable force in his spirit, keen senses and superhuman strength. But since they were unable to break his spirit, Leatherhead eventually escaped through the portal that they used to travel to Earth. Stealing the power cell that powered the portal, he returned to the sewers and guarded the cell with a maze of booby traps, swearing to keep it away from the Kraang (so they wouldn't start their invasion) at the cost of his own life. 6 months later, the Kraang found him attacking sewer workers near his lair and demanded the power cell's location. The Turtles saved him, and after being convinced by Michelangelo to take him back to their lair to be nursed back to health, the other three Turtles went out to find the power cell. Unfortunately, Leatherhead attacked them after finding out and went berserk, only to be kicked out of the lair by Splinter. Michelangelo, feeling sorry for his new friend, followed him back to his lair (with the other Turtles following), where Leatherhead explained the power cell's purpose and entrusted it into their hands as soon as the Kraang returned to demand it back. After the Turtles lost the cell to the Kraang, they went to Leatherhead to ask for the portal's location, and in return, he helped them fight against Traag when the Kraang used the portal to bring him through. However, when they started using the portal to bring something else (possibly Granitor) through, Leatherhead sacrificed himself by entering the portal to stop it, dragging Traag with him. He was later revealed to have survived the portal closing and has rapidly aged (due to the time difference between Earth and Dimension X). After sending a message to the Turtles through a Kraang communication orb warning them that the Kraang have perfected their mutagen, Michelangelo led a rescue mission for Leatherhead and together they stopped the Kraang from pouring the mutagen through the various portals while Donatello closed them all down, thus leaving one open for them to return to their own dimension. As soon as the Kraang's invasion started, Leatherhead accompanied Splinter with finding the Turtles (who fled the lair when the Kraang invaded it) until they were cornered by Shredder, who seemingly killed him by slicing into his hide and sending falling into the river. He survived the wounds, however, and was later recruited as second-in-command of the Mighty Mutanimals as they worked with the Turtles to take back the city from the Kraang.
  • Pete (voiced by A. J. Buckley) - An common wood pigeon that was mutated by the Kraang into a humanoid mutant wood pigeon with a tan human-like torso, razor-sharp talons and mutagenic growths all over his body and kept as their prisoner. During his captivity, he shared a cell with Kirby O'Neil, who taught Pete how to speak and had him deliver a message warning of a mutagen bomb the Kraang planned to detonate on the city to his daughter, following either Pete's release by the Kraang or escape from their custody. Pete stalked April for a few days and frightened her with his alleged attack before the Turtles ambushed him and tackled him to the ground. Despite being captured, he was able to tell them his true intentions and delivered April Kirby's message before leading her and the Turtles to the Kraang base where Kirby was being held. Pete was later recruited as a spy for the Mighty Mutanimals, helping the Turtles take back the city from the Kraang.
  • Dr. Tyler Rockwell / Monkey Brains (voiced by Tom Kenny with vocal effects provided by Frank Welker) - Tyler Rockwell was a British neurochemist who was mutated into a mutant monkey by Dr. Victor Falco.
  • Garson Grunge / Muckman (voiced by Nolan North in earlier appearances, Grant Monninger in later appearances) - Garson Grunge was a humble sewer worker who had encounters with mutants in the past, such as getting attacked by Leatherhead, a Squirrelanoid, Fungus Humongous' fear spores and Pizza Face's minions. Following the end of the Kraang's invasion on the city he began working as a garbageman until he heard a commotion involving the Turtles fighting Bebop and Rocksteady at an abandoned Kraang lab and got hit in the face with a canister of mutagen (which Bebop intentionally threw at Michelangelo) while investigating it. As the result of falling into the dumpster, Grunge mutated into a 6 ft. humanoid mutant made entirely out of garbage with a banana peel cap, an exposed and eroded skeleton, a toxic vomit, control over other garbage and dissolving abilities that the press dubbed "Muckman". Convinced by Joe Eyeball to be a hero when he found the Purple Dragons mugging a man, Muckman stopped them and beat them up. The man witnessed the action and talked about it on Joan Grody's show, becoming New York's new sensation. When the Turtles and April found Muckman and Joe Eyeball, Muckman blamed the Turtles for his mutation, yet both groups had to leave before Joan Grody could get a full glimpse of the Turtles. Upon seeing the news on Muckman, Bebop and Rocksteady planned to take advantage of this and looked for him. When they found him, he thought they were with the Turtles until they claimed that they weren't with them. They then convinced him to help them rob a Kraang lab again by claiming that it contains a cure, though Joe became suspicious of their motives. When the Turtles caught up to them, Muckman began to attack, but Bebop stopped him and told him to get the chemical while he and Rocksteady dealt with the Turtles. Muckman joined the fight and the Turtles were defeated, but they tried to reason with him and were all knocked out by Bebop's grenade. Rocksteady threw Muckman into the lab and is blasted with the Kraang's traps. Muckman found the chemical they were looking for but was blasted by another trap as Rocksteady took it from him. As a result, Muckman helped the Turtles by shooting slime at the chemical, destroying it while allowing Bebop and Rocksteady to retreat. After apologizing to the Turtles, he covered up their existence by telling Joan Grody that they were just people in costumes like the Pulverizer.
  • Joe Eyeball (voiced by Grant Monninger) - Muckman's partner and conscience, which was originally Garson Grunge's left eye until it gained a form of his own during the mutation.

As the result of placing his pet leopard gecko, Lars, on his shoulder, he mutated into a 4 ft. humanoid mutant leopard gecko and was left by his parents out on the streets, where he spent his days skateboarding until he was taken in as an errand boy by Fishface (who was called "Mr. X" by his underlings). Fortunately, Mondo made quick friends with Michelangelo and Casey Jones, and eventually saw the true colors of his boss when he was challenged to race against him.

Villains

• The Foot Clan - A power-hungry and barbaric ninja clan that was founded 1,500 years ago in Japan by an 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. Although wiped after a long conflict with the Hamato Clan under the leadership of Takuza's recently-perished descendant, Oroku Kaiji, the clan itself was restored into a national crime syndicate by Kaiji's son, Oroku Saki, as he inherits the Kabuto and rechristens himself as "the Shredder".
  • Oroku Saki / Shredder (voiced by Kevin Michael Richardson) - The leader of the Foot Clan and one of the primary antagonists of the series. Oroku Saki was the son and heir of Foot Clan leader Oroku Kaiji, who was orphaned as a baby when the Foot went extinct after a long-term conflict with the peacekeeping Hamato Clan. However, when the Hamato Clan leader Hamato Yuta, discovered the poor Saki in the blazing ruins of the Foot Clan as another son. Despite being raised as brothers, both Saki and Yoshi eventually became rivals due to the love of Tang Shen, whose decision to marry Yoshi drove Saki to discover his true heritage and turn on his former brother, eventually destroying everything Yoshi held dear, including Tang Shen (who Saki killed by accident) and the entire Hamato Clan (starting with the destruction of the Hamato Clan monastery, which resulted with Saki's head getting burned scarred and hairless). Blaming Shen's death on Yoshi, Shredder decided to spare Yoshi and Shen's baby daughter Miwa and raise her as Karai while transforming the newly restored Foot Clan into a powerful crime syndicate. Fifteen years later, after learning of Yoshi's continued existence and students in New York, Shredder traveled there to seek revenge. After several attempts kill the Ninja Turtles, he learned of the Kraang through Karai, but was uninterested in what use they have for his cause until he found that their resources, including mutagen (which eventually created the Turtles and turned Yoshi into Splinter) were a great use of upgrading the Foot into mutants and robots. Shredder later captured a Kraang after finding out that it and it's race were hunting the Turtles as well. This had him to form an alliance with the Kraang to move him closer to Splinter, but it dissolved after a number of incidents, leaving the Foot to recruit his own mutants and continue their conflict with the Turtles. The conflict at first started to improve with Splinter drawn out and April O'Neil and Casey Jones revealed as Turtle allies, but was then pushed in the other direction when the Turtles exposed the truth to Karai, who got mutated into a snake while facing Shredder alone. Enraged, Shredder renewed his alliance with the Kraang and helped them take over the city, which not only exposed Shredder's true nature to the world but also made him the dominant power of New York's criminal underworld.
  • 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. When Shredder learned of Splinter's presence in New York, he sent Bradford with Xever Montes (Fishface) to find and kill both him and the Turtles, first tricking Michelangelo into a faux friendship on a social media website. Bradford revealed his deception when he had Michelangelo captured, sparking a bitter hatred from him. However, after failing to trick the Turtles into leading him and the Foot to Splinter and numerous repeated failures, Shredder became enraged at his incompetence. Fortunately, Bradford was prepared to die with honor than continue his life of shame when confronting the Turtles near a Kraang mutagen bomb with Montes. In a final attempt to finish them off, he stabbed open the mutagen bomb, which instead caused the mutagen inside to wash only him and Montes off the building. As the result of getting bitten in the knuckles by Shredder's pet akita Hatchiko, Bradford mutated into an 8 ft. humanoid mutant akita with a spiked back, a large left arm, heightened senses and superhuman strength that Michelangelo dubbed "Dogpound". Despite being stronger, Dogpound continued to be more incompatible at carrying out the Foot's plans due to gaining less agility than he was as human. He eventually found hope when Karai ordered him to return Baxter Stockman (Stockman-Fly) back into the Foot, believing that he could retro-mutate him. However, during a fight with Michelangelo in Stockman's lab, Dogpound fell into the lab's mutagen vat and mutated into a near-skeletal werewolf-like version of his previous form with amazing agility an bony claw projection that Michelangelo dubbed "Rahzar". Having to have regained his speed and reflexes, Rahzar proved to be more deadly than before but was tricked by Michelangelo into attacking the power generators and electrifying himself and the rest of the Foot Clan. When Shredder returned from Japan, he commented that Rahzar looked terrible, but continued to employ him as an operative.
  • 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, learning how to survive on his own by pick-pocketing. Over time, he developed his thievery ways very professionally by stealing from private property, but was finally caught by the authorities one night while burglarizing a briefcase that was later revealed to be Foot Clan property and put in prison. However, this was until he was bailed out and recruited into the Foot Clan by Shredder, who trained him as his street contact and a cut-throat killer armed with a pair of butterfly knives. When Shredder learned of Splinter's presence in New York, he sent Montes with Chris Bradford (Dogpound / Rahzar) to find and kill both him and the Turtles, but the plan to trick the Turtles into leading them to Splinter failed. As a result, Shredder put the clan under Montes's command, much to Bradford's dismay. After learning of the Purple Dragons' fight with the Turtles at Mr. Murakami's noodle shop, Montes held Murakami hostage in order to draw out the Turtles (who held Bradford hostage in return). However, after failing to trick the Turtles to sacrifice their lives for Murakami (mainly because of Fong's mercy for Leonardo) and numerous repeated failures, Shredder became enraged at his incompetence. He later mutated into the mutant snakehead Fishface after touching a snakehead in a Chinatown marketplace. Following the mutation, he wears a water-breathing rig and mechanical legs.
