Main characters In most versions, the Teenage Mutant Ninja Turtles are created when four baby turtles are exposed to radioactive ooze, transforming them into humanoids.

Leonardo

Leonardo, nicknamed Leo, is the leader of the ninja turtles, as well as the most disciplined and skilled. Naturally stoic and mature beyond his years, his main priority is to help his brothers to be the best ninjas they can. Because of his leadership, he is often challenged with the constant rebelliousness of Raphael. An expert swordsman, he wields two katanas and wears an ocean blue mask.

Donatello

Donatello, nicknamed Donnie, is the smartest and gentlest of the Turtles. An intellectual, he often attempts to reach his goals through science and technology rather than through violence and so frequently invents gadgets and vehicles. He is typically the passive turtle and Leonardo's second-in-command, always one step ahead of his brothers and coming up with solutions to complex problems when they cannot. Studying the art of Bojutsu, he wears a purple mask and wields an oak bō.

Raphael

Raphael, nicknamed Raph, is the most aggressive and temperamental of the turtles. Rebellious, cynical, and quick witted, he is often driven by his strong emotions and is more prone to temper loss than his brothers. He possesses a strong desire for independence, often going rogue whenever opportunity calls for it and displaying disapproval of authority. His quick temper tends to get the better of him, but he openly loves his family, and is fiercely loyal to his allies. He wears a red mask and wields a pair of sai.

Michelangelo

Michelangelo, nicknamed Mikey, is the least disciplined and most fun-loving turtle. He is usually portrayed as the most agile and naturally gifted, contrasting his free spirit and inability to take training seriously. The most stereotypical teenager of the team, he is an avid fan of pop-culture and often speaks with a surfer dialect. He yearns to live life to the fullest, resulting in a tendency to fool around whenever possible. He wears an orange mask and fights using nunchucks.

Splinter

Splinter is the mutant rat sensei and adoptive father of the Ninja Turtles. Generally depicted as wise and powerful, he raised the four turtles and trained them in the art of Ninjutsu. He is very cautious and protective of them, constantly warning them of the dangers on the surface. In stark contrast to his coarse gnarly appearance, Splinter always speaks in a quiet gentle dignified voice.

April O'Neil

April O'Neil is a confident, courageous, benevolent, intelligent, and outgoing human companion of the Ninja Turtles. She met the Turtles when they saved her from a group of Shredder’s henchmen chasing her down the sewers. She embarked on many of the Turtles' adventures and aids them by doing the work in public while the Turtles cannot.

Casey Jones

Casey Jones is a hockey-masked vigilante, armed with an assortment of sporting goods that he carries in a golf bag. He is a close ally of the Ninja Turtles, whom he met after having a martial-arts skirmish with the temperish Raphael regarding Casey's own inflamed behavior when battling the bad guys.

Recurring characters Hamato Yoshi Hamato Yoshi is a ninjutsu master whose history is always intertwined with Splinter's. In most versions, Splinter is either his pet rat or a mutated form of Yoshi himself.

Mighty Mutanimals The Mighty Mutanimals, a superhero group within the Teenage Mutant Ninja Turtles (TMNT) franchise, emerged in the comic-book series Teenage Mutant Ninja Turtles Adventures. Composed of various mutated animals, the team collaborated with the TMNT and has been featured in multiple iterations of the franchise since its inception.

In Teenage Mutant Ninja Turtles: Mutant Mayhem, the Mutanimals are former allies of Superfly who turned on him and allied with the Turtles.

Dreadmon Dreadmon is a native of South Africa. During an uprising, his father sent him and his mother to Jamaica, where they suffered from poverty. Dreadmon became a thief and eventually stole a talisman that transformed him into a red wolf hybrid.

Dreadmon appears in the IDW Publishing comics where he is depicted as a mutant black-backed jackal.

Jagwar Jagwar is a humanoid jaguar who is the child of a jaguar spirit and a tribal woman named Juntarra. After his mother left to continue her personal quest (completing "The Path of the Four Winds"), Jagwar lived in the rainforests of Brazil until his discovery by the TMNT in issue #14. Soon afterward, Jagwar became the leader of the Mighty Mutanimals.

In IDW Publishing, Jagwar is depicted as an anthropomorphic jaguar goddess and member of the Pantheon.

Leatherhead Leatherhead is a mutant American alligator and hot-headed ally of the Ninja Turtles.

In the Mirage continuity, Leatherhead was originally an ordinary alligator who escaped a pet store during a robbery and found his way into the sewers. While in the sewers, Leatherhead was found by a pair of TCRI Utroms and later mutated.

In the Archie Comics series Teenage Mutant Ninja Turtles Adventures, Leatherhead is a human named Jess Harley who lived in the swamps of Florida, and was transformed into a mutant alligator when Dimension X warlord Cherubae uses the Turnstone on him. At first, Shredder lures Leatherhead to work with him, until Leatherhead discovers that the Shredder is a villain. Leatherhead later becomes a wrestling hero at the Stump Asteroid and later a member of the Mighty Mutanimals.

Leatherhead makes his debut in the 49th issue of IDW Publishing's comic series. He appears very briefly, telling Dr. Harold and Professor Honeycutt that he had some mutagen that could be used to help heal Donatello.

Leatherhead in other media Leatherhead appears in Teenage Mutant Ninja Turtles (1987), voiced primarily by Jim Cummings and by Peter Renaday in the episode "Night of the Rogues". A green check mark indicates that a role has been confirmed using a screenshot (or collage of screenshots) of a title's list of voice actors and their respective characters found in its credits or other reliable sources of information. This version is a wild alligator who was mutated by mutagen that entered the swamp after a botched mission by Krang and Shredder and later becomes Shredder's ally. Leatherhead appears in Teenage Mutant Ninja Turtles (2003), voiced by Frederick B. Owens in the second and third seasons and by Gary K. Lewis in the fourth and seventh seasons. This version was originally an exotic pet who got flushed down to the sewer, where he was found and mutated by the Utroms. He was accidentally left behind during Shredder's attack, which forced the Utroms to flee Earth, and comes to live with the Turtles. After inadvertently attacking Michelangelo, Leatherhead chooses to live in an abandoned subway station near the Turtles' base, allowing him to keep in touch with them while ensuring their safety.
