Overview Teenage Mutant Ninja Turtles •
Leonardo (voiced by
Cam Clarke) – The blue-masked turtle who wields two
katana. He is the leader and commander of the Turtles and is the closest to Splinter. He is the most serious, level-headed member of the team, who values his leadership. •
Donatello (voiced by
Barry Gordon in most episodes,
Greg Berg in six Season 3 episodes and one episode of the "Vacation in Europe" side-season) – The purple-masked turtle who wields a
bō staff. He is the scientist and intellectual of the team who is constantly tinkering with various inventions. Donatello's capabilities in science and technology have been key factors for the Turtles' successes in their battles with Shredder and other villains. •
Raphael (voiced by
Rob Paulsen in Season 1–9, Thom Pinto in two Season 3 episodes,
Hal Rayle in the "Vacation in Europe" side-season,
Michael Gough in Season 10) – The red-masked turtle who wields two
sai. Although Raphael is depicted as angry, impulsive, and violent in most other
TMNT media, he is the comedian of the team who often comes out with sarcastic and witty remarks in the 1987 series. He provides some of the comic relief for the show, constantly breaking the fourth wall. •
Michelangelo (voiced by
Townsend Coleman) – The orange-masked turtle who wields a pair of
nunchakus, which is later changed to a
grappling hook. He is the goofy, fun-loving "party animal" of the team who often speaks in surfer slang, and is the source for many of the show's
catchphrases, such as "Cowabunga!". More so than any other Turtle, he is obsessed with
pizza and enjoys experimenting with various toppings, even when the other Turtles find it gross. He is also considered to be the least intelligent member of the team, especially by Raphael. Michaelangelo is the most laid back character, though he is shown to be very skilled with his nunchaku. He also provides much of the comic relief albeit without Raphael's sarcasm.
Allies and friends •
Master Splinter/Hamato Yoshi (voiced by
Peter Renaday in most appearances,
Townsend Coleman in two Season 5 episodes) – A soft-spoken yet strict and wizened sensei who used to teach Oroku Saki, until the latter set him up for an offense towards his master which he did not commit and was exiled from the Foot Clan. Since then, he has lived in the sewers of Manhattan as a homeless man with the rats and his four pet turtles as his only friends. Upon being exposed to the same mutagen that changed the turtles into their present anthropomorphic forms with his DNA, Hamato Yoshi transformed into a humanoid mutant
rat (as he had most recently been with the rats) and raised the Turtles as his sons (who nickname him "Splinter" from his habit of breaking wood), training them in
ninjutsu. It is later revealed that one of his distant ancestors was the founder of the Foot Clan. • '''
April O'Neil''' (voiced by
Renae Jacobs) – A redheaded TV reporter from Channel 6 News (later a freelance reporter in Seasons 9 and 10) who discovers the Turtles' home in the sewers and befriends the TMNT. She is frequently kidnapped by Shredder and other villains, usually as bait to lure the Turtles out of hiding. •
Irma Langenstein (voiced by
Jennifer Darling) – Channel 6's clumsy, dating-obsessed secretary who debuts in Season 2. She is April's best friend who later also befriends the TMNT. Following the destruction of the Channel 6 Building in Season 8, Irma is slowly phased out of the show. A similar character would be used in the
2012 series. •
Casey Jones (voiced by
Pat Fraley) – A violent, impulsive, and overzealous street-fighting vigilante who is friends with the Ninja Turtles. He fights using sports equipment and wears a hockey mask. •
Zach "the Fifth Turtle" (voiced by
Rob Paulsen) – A 14-year-old who looks up to the Turtles and is their biggest fan. • '''''' (voiced by
Townsend Coleman) – Zach's older brother. •
Punk Frogs – The mutant
frog counterparts of the TMNT who were accidentally mutated by Krang and trained in martial arts in the hopes that they would be a match for the Turtles. Further emulating his rival Splinter, Shredder names the four frogs after his own personal heroes:
Attila the Hun,
Genghis Khan,
Napoleon Bonaparte, and
Grigori Rasputin. Despite their innocent, docile nature, they are also extremely naive, and as such, they were easily misled by Shredder into believing that the Turtles were "evil" and that Shredder was a "good person". However, they eventually turned against Shredder and became their allies. These frogs all speak with Southern American accents. •
Attila the Frog (voiced by
Cam Clarke) – A Punk Frog who wields a mace. •
Genghis Frog (voiced by
Jim Cummings) – A Punk Frog who wields an axe. •
Napoleon Bonafrog (voiced by
Pat Fraley) – A Punk Frog who wields a whip. •
Rasputin the Mad Frog (voiced by Nicholas Omana) – A Punk Frog who wields a bow and arrow. • '''''' – An alien race of teenagers from Dimension X whose only goal in life is to have fun. •
Dask (voiced by Thom Pinto) – A male Neutrino. He spends some time tinkering with his Starmobile. •
Kala (voiced by
Tress MacNeille) – A female Neutrino. She seems to have the strongest friendship with Michelangelo out of all the Turtles. • '''''' (voiced by
Pat Fraley) – A hipster Neutrino. • '''''' (voiced by
Jan Rabson impersonating
Cliff Edwards) – A native of the distant utopian planet Shell-Ri-La (the name being a pun on
Shangri-La), which is home to a peaceful, but generally defenseless
alien humanoid turtles called the Turtleoids. He arrives on Earth to seek for the Turtles' help in protecting his homeworld from a few threats. • '''''' (voiced by
Bumper Robinson) – Introduced in Season 9, he travels to New York City to study martial arts under Splinter, but is accidentally exposed to a mutagen which causes him to spontaneously oscillate between his human and mutant forms. He was an important ally to the TMNT in their battles against Lord Dregg. In Season 10, he temporarily leaves to finish his studies after Donatello stabilized his mutation, although he returns upon learning from April that the Turtles were captured by Dregg, Krang, and Shredder. While on his way to rescue the Turtles, Carter found that he could still mutate. At the end of "Turtles to the Second Power", Carter accepts Landor and Merrik's offer to travel with them to the future so he can be fully cured of his mutation. •
Landor and Merrik (voiced by
Kevin Schon and
Roxanne Beckford) – Two time-travelers from the future.
Villains Main villains •
The Foot Clan – An evil ninja organization. •
Oroku Saki/The Shredder (voiced by
James Avery in Season 1 to the first half of Season 7,
Dorian Harewood in four Season 3 episodes,
Pat Fraley in one Season 3 episode,
Jim Cummings in one Season 5 episode and most of the European side-season,
Townsend Coleman for the second half of Season 7, and
William E. Martin in Season 8 and 10) – The nemesis of the Turtles and Master Splinter. He is usually the main villain in other media, but in this series Shredder always, against his will, has to take orders from Krang, although their relationship evolves over time into more of an equal partnership (with Shredder even risking his life to save Krang on numerous occasions). His real name is Oroku Saki, a member of the Foot Clan in Japan and a student of Hamato Yoshi/Splinter. Saki was jealous of Yoshi's leadership within the Clan and sought to usurp him. He responds by framing Yoshi for an offense towards the sensei and has him exiled. Shortly afterwards, Saki takes control of the Foot Clan and transforms it into an army of crime under his command. Along with Krang, Rocksteady, and Bebop, he is the primary antagonist of the show until the end of Season 8, when the Technodrome is destroyed and they are all banished to Dimension X. Although he and Krang return for three episodes in the final season, they are eventually sent back to Dimension X, and they are not seen again for the rest of the series. •
Rocksteady (voiced by
Cam Clarke) – One of Shredder's incompetent, oafish henchmen. Originally the Caucasian male leader of an unnamed street gang, Rocksteady was mutated into a humanoid black rhinoceros. Like Bebop, he is extremely unintelligent (although he is shown on multiple occasions to be slightly more intelligent than Bebop) and serves as comic relief for most of the series. •
Bebop (voiced by
Barry Gordon in most episodes,
Greg Berg in six Season 3 episodes and one episode of the "Vacation in Europe" side-season) – An African-American male with a mohawk, sunglasses, and a nose ring who, along with Rocksteady, is one of Shredder's henchmen. Prior to meeting Shredder, he belonged to the same street gang as Rocksteady, serving as the latter's second-in-command. As part of Shredder and Krang's experiment, he was transformed into a humanoid
common warthog. •
Baxter Stockman (voiced by
Pat Fraley) – A blond Caucasian
inventor (as opposed to the dark-haired African-American he was portrayed as in the Mirage comics) who tried to bill his rat-catching Mousers to the Ajax Pest Control company. They did not like his suggestion, saying it would put them out of business, and threw him out of the building. Embittered, he readily agrees to join forces with Shredder, who orders him to replicate his Mousers and hunt down Splinter and the Turtles. After the Ninja Turtles defeated the Mousers, Baxter Stockman was arrested and thrown into an asylum. Shredder later traded Stockman to Krang for the return of Bebop and Rocksteady. When Krang found no use for Stockman and decided to kill him, a
fly that had been with Baxter in the disintegrator unit soon merged with him, turning him into a humanoid fly. He has occasionally plotted revenge against the Ninja Turtles and Shredder. Baxter Stockman has a twin brother named Barney who was also a mad scientist and threw fits whenever the Turtles mistook him for Baxter. •
Z (voiced by
Townsend Coleman) – A sentient computer found on an abandoned spaceship who allied with Baxter Stockman. •
Chrome Dome (voiced by
Peter Renaday) – A towering robot who was created by Shredder to keep an eye on the Foot Soldiers in the episode "Planet of the Turtleoids". It was destroyed during its fight with the Turtles. In "Night of the Rogues", Chrome Dome was rebuilt by Shredder and is among the villains who Shredder recruited to attack the Turtles. •
Foot Soldiers – A group of robotic ninjas who serve Shredder. •
Krang (voiced by
Pat Fraley in most episodes,
Townsend Coleman in three Season 3 episodes) – An extremely intelligent, disembodied brain from Dimension X who commands the
Technodrome. Like Shredder, he aspires to conquer the Earth, although he does not share Shredder's obsessive hatred of the Turtles and Splinter (instead of viewing them as more of an annoyance/obstacle), preferring instead to focus on world conquest. He funds and helps plan most of Shredder's schemes, although they often bicker with one another over tactics. In Season 7, it is revealed that Krang was originally a
Tyrannosaurus-like creature with regenerative powers before he lost his body and was banished from Dimension X. •
Rock Soldiers – The Rock Soldiers are an army of sentient rock humanoids from Dimension X. As mentioned in "Michaelangelo's Birthday," the Rock Soldiers were created when Krang used mutagen on some rocks. The Rock Soldiers are incredibly strong, but they are not very bright. •
General Traag (voiced by
Peter Renaday) – Traag is a Rock Soldier general who is loyal to Krang. •
Sergeant Granitor (voiced by
Pat Fraley impersonating
Peter Lorre) – Granitor is a high-ranking gray Rock Soldier who is loyal to Krang and works under General Traag. • '''''' (voiced by
Tony Jay) – An alien
warlord who serves as the chief
antagonist for the final two seasons of the series, following Shredder and Krang's exile to Dimension X in Season 8. At the end of the final season, Dregg is banished to Dimension X as well. Although he starts out as a cold, calm, and calculating villain, his sanity gradually deteriorates over the course of Season 10, as he becomes increasingly obsessed with destroying the Turtles once and for all. In the process, he alienates all of his remaining followers, including his second-in-command Mung, who accuses him of losing sight of their quest for world domination. •
HiTech (voiced by
Rob Paulsen in Season 9,
Cam Clarke in Season 10) – An
arthropod-like alien in high-tech armor who served as Dregg's second-in-command. When Mung proves more efficient as second-in-command, Dregg blasts HiTech off in a pod to "orbit the galaxy". •
Mung (voiced by
Cam Clarke) – A hunchbacked
beetle-like henchman of Dregg who replaced HiTech in the final season. He is a technical and mechanical genius where he even surpasses HiTech himself. Mung usually supplies Dregg with his self-replicating "microbots" to build whatever he wants in a matter of hours. •
TechnoGang – A gang of
insect-like foot soldiers who serve Dregg. •
Batmen – A group of ugly winged humanoid bats who serve as the alternate foot soldiers for Dregg.
Recurring villains •
The Street Gang – A street gang that Bebop and Rocksteady lead. It is loosely based on the
Purple Dragons from the comics. •
Scrag – A member of Bebop and Rocksteady's faction with wild red hair and wears sunglasses. He got mutated into a mutant
bat. Scrag's name came from the original storyboard for "Turtle Tracks" and a coloring book. •
Grunt – A member of Bebop and Rocksteady's faction who sports a yellow mohawk and wears sunglasses. He got mutated into a mutant
lizard. His name came from the original storyboard for "Turtle Tracks." •
Dopey – A cap-wearing big-nosed member of Bebop and Rocksteady's faction who got partially-mutated into a mutant
elephant where he sported an elephant trunk and an enlarged right arm. His name came from the original storyboard for "Turtle Tracks." •
Dumbo – A short, fat, and bald-headed member of Bebop and Rocksteady's faction who got mutated into a mutant
three-toed sloth. His name came from the original storyboard for "Turtle Tracks." • '''Lugnut's Gang''' - There is the street gang that is led by Lugnut who Bebop and Rocksteady's faction are associated with. It is also loosely based on the
Purple Dragons from the comics. •
Lugnut (voiced by
Townsend Coleman in "The Gang's All Here," Nicholas Omana in "Once Upon a Time Machine") – The bald-headed leader of the gang that Rocksteady and Bebop's faction are a part of. •
Jersey Red (voiced by
Renae Jacobs) – A tough woman who is a member of Lugnut's faction. •
High Five (voiced by
Rob Paulsen) – A member of Lugnut's faction. •
The Rat King (voiced by
Townsend Coleman) – A homeless man living in a dilapidated portion of the New York City sewer system, not too far from the Turtles and Splinter. He usually carries around a hypnotic
flute to mesmerize any rodent nearby, especially mutant rats. In these episodes featuring him, the Rat King would often enact some sort of plot to establish his own rat-controlled government and end human rule forever, thus believing that all rats (which he counted himself as) were more superior than every other species, whom he described as "inferior non-rodents". The Rat King appeared as a recurring villain from Seasons 3 to 7 onwards, until he is finally apprehended by the police in the second episode of Season 8. •
Leatherhead (voiced by
Jim Cummings in three appearances,
Peter Renaday in "Night of the Rogues") – A large
alligator from
Florida who has mutated into humanoid form when he swam through a mutagen-polluted part of his swamp. He hunted the Turtles' allies the Punk Frogs, and then went to New York to hunt the Turtles themselves. One time, he fights the Rat King, but join forces with him in later episodes. •
Slash (voiced by
Pat Fraley) – An ordinary
turtle from Earth who was mutated by Bebop and Rocksteady. He is a muscular, vicious humanoid turtle with brute strength, dynamic durability, spikes on his shell, vortex breath, hardened claws, and a pair of
Shaolin swords, but very low intelligence (although he does temporarily acquire a genius-level IQ in his second appearance). Slash is also extremely attached to a small, plastic palm tree standing inside the bowl prior before exposure of super mutagen and calls it his "binky". •
Organised crime figures - The Teenage Mutant Ninja Turtles have gone up against different members of Manhattan's criminal underworld. •
Don Turtelli (voiced by
Peter Renaday) - A
crime boss known for using feathers to tickle his victims' feet. •
Pinky McFingers (voiced by
Peter Renaday in most appearances,
Cam Clarke in "Donatello's Duplicate") – A high-ranking crime boss with a gang at his disposal. McFingers once sponsors Baxter Stockman's twin brother Barney Stockman to create a "gag-a-magnifier" device that increases the comedy power of jokes. They planned to hook up the funniest comedian to it and transmit the joke waves all over the city, making everyone hysterically helpless. This enabled McFingers and his two goons would go out and rob the city. He and his men kidnapped comedians until they kidnapped Raphael. They tied Raphael up in a sack and took him to their hideout where strapped down, McFingers tells him of his brilliant plan. Being the funniest comedian, Raphael is forced to start telling his jokes. However, the rest of the turtles rescue him and the other comedians and turn the device against Stockman and the McFingers gang, all of whom end up arrested. •
Big Louie (voiced by
Peter Renaday) – A high-ranking
gangster with a gang at his disposal who sometimes works with the Shredder. •
Mad Dog McMutt (voiced by
Townsend Coleman) - A bulldog-like human gangster. His secret headquarters is a giant fire hydrant and he has a dog-shaped car and helicopter. •
Tempestra (voiced by Gaille Heideman) – A
sorceress from the arcade game "Tempestra's Revenge" who was brought out by a freak thunderstorm. She possesses telekinetic powers, can create different creatures to fight for her, and can control the weather. After Leonardo encountered Tempestra upon playing the arcade game, he called in the rest of the Turtles to fight her. Tempestra was defeated when Leonardo trapped her in the circuit board from the wrecked arcade game. In "Night of the Rogues", Tempestra was freed offscreen by Shredder who is among the villains used by him and Krang to destroy the Turtles where she was the one who led them. Tempestra has also appeared in three video games associated with this show. •
Groundchuck and Dirtbag (voiced by
Robert Ridgely and
Pat Fraley) – A mutant red-furred
cattle in armor and a mutant
mole who were accidentally created by Shredder's mutagen due a series of events caused by Kerma. •
H.A.V.O.C. – Short for Highly Advanced Variety Of Creatures, H.A.V.O.C. is a gang of mutants. The Turtles meet H.A.V.O.C. in the process of thwarting a robbery, meeting mutants and H.A.V.O.C. members Raptor, Amok, and Overdrive, and then later, the H.A.V.O.C. leader, Titanus. The Turtles find out that while H.A.V.O.C. has offered the Turtles a safe haven from those who think they are the villains, H.A.V.O.C. is actually creating mutants instead of protecting them and actually tries to turn the entire city into mutants. The Turtles spend a few episodes of season 8 battling H.A.V.O.C. After they get rid of the boss, none of the other mutants appear again. •
Titanus (voiced by
Ron Feinberg) – A large unspecified mutant from the future who is the leader of H.A.V.O.C. In his final appearance, he ends up trapped in the time of dinosaurs and vows to have revenge against the Turtles if it is the last thing he ever does. •

In H.A.V.O.C. in the Streets, Titanus breaks him out of jail and turns him into an electric mutant. Synapse keeps the Turtles busy for a while until Donatello forces him through a ham radio, leaving him trapped on the radio airwaves.
Other characters •
Channel 6 News Staff – The workers of Channel 6 News that often have involvements with the Ninja Turtles. Following the destruction of the Channel 6 News building during Season 8, these characters slowly faded out of the series. The old Channel 6 building also made a cameo appearance in the crossover movie
Turtles Forever as the 2003 Turtles take a detour in the dimension of their 1987 counterparts. • '''''' (voiced by
Pat Fraley in most episodes,
Townsend Coleman in three episodes of Season 3) – April's stubborn and irascible boss at Channel 6 News, and the human antagonist of the Turtles. He wrongfully believed the Turtles were a "menace" and bullied April to expose them since he usually had to pay for the damages caused by the Turtles' battles. His hatred for the TMNT intensified following the destruction of the Channel 6 building by Shredder in Season 8, an incident he falsely blamed on the Turtles. He often favored Vernon more, which was likely due to the fact that Vernon shared Burne's distrust of the TMNT and did not hesitate to cast a negative light on them in his news coverage. In the 2014
Teenage Mutant Ninja Turtles film, a genderbent adaption of this character named
Bernadette Thompson was used where she was portrayed by
Whoopi Goldberg. • '''''' (voiced by
Pat Fraley in Season 1,
Peter Renaday in Seasons 2–8 and
Townsend Coleman in one Season 5 episode) – April's cameraman, rival news reporter, and the second human antagonist of the Turtles. In Season 1, he had more of a serious and dedicated personality, although shades of the cowardice and rivalry with April that would define Vernon's character throughout the rest of the series would sometimes surface. Despite that, he was still willing to help April get her story in the Season 1 finale, "Shredded and Splintered". From Season 2 onwards, he was written as a selfish, egotistical, opportunistic, and cowardly cameraman and co-reporter who would often go to great lengths to steal April's thunder, although he was quick to cede all of the more "dangerous" assignments to April, not willing to put himself in harm's way. Like Burne, he also wrongfully believed that the Turtles were a menace to society and often actively participated in Burne's anti-mutant campaigns, even though the Turtles had saved his life on many occasions. Vern appears in the 2014 TMNT film and its
2016 sequel portrayed by
Will Arnett. ==Production==
