Main characters[edit]

In most versions, the Teenage Mutant Ninja Turtles are created when four baby turtles are exposed to radioactive ooze, transforming them into humanoids.[1]


Leonardo, nicknamed Leo, is the leader of the Ninja turtles, as well as the most disciplined and skilled. His main priority is to help his brothers to be the best ninjas they can. Because of his leadership, he's often challenged with the constant rebelliousness of Raphael. An expert swordsman, he wields two katanas and wears an ocean blue mask.[2]


Raphael, nicknamed Raph, is the most violent and temperamental of the turtles. Rebellious, cynical, and quick witted, he is often driven by his strong emotions. He possesses a strong desire for independence, and often displays animosity towards his brother Leonardo over his leadership and their conflicting methods. His quick temper tends to get the better of him, but he openly loves his brothers, father, and allies.[1] He wears a red mask and uses a pair of sai.[2]


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.[1] Studying the art of Bojutsu, he wears a purple mask and wields an oak .[2]


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.[1] The most stereotypical teenager of the team, he often speaks with a Southern Californian dialect and expresses his love of pizza whenever brought up. He wears an orange mask and fights using nunchucks.[2]


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[edit]

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 squadron of MOUSERS 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[edit]

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[edit]

Hamato Yoshi[edit]

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[edit]




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

Mondo Gecko[edit]

Ray Fillet[edit]

Wingnut and Screwloose[edit]


Slash is a humanoid turtle who is either an enemy or ally of the Ninja Turtles depending on the version.

In the Archie comics continuity, he is a turtle-like alien from a tropical planet in Dimension X. Slash's home world was eventually destroyed by alien invaders, leaving him the only homeless survivor of his kind. He was later found by Krang, who made a deal with him to find his way back to Earth, and in return, Slash came under the former's leadership and kept the Ninja Turtles busy while Krang sought to possess Shredder's body, but to no avail. Slash's rampage caught the attention of the Mighty Mutanimals, who captured him and brought him to their island. With Leatherhead's help, Slash was able to control his violent spree and informed that he would be allowed to stay in a grove of lush palm trees he so loved. Grateful, he went on to become a member of the Mutanimals, ultimately sacrificing himself later to save the Turtles.

In the 1987 animated series, Slash (voiced by Pat Fraley) was Bebop's pet turtle, mutated by Rocksteady to carry out an assignment that Shredder wanted them to do. However, when the plastic palm tree he loved in his tank was accidentally dropped down an air duct by Bebop, Slash went berserk and stole Shredder's shaolin, chasing them around the Technodrome before going to Earth on Bebop's part. There, he ran into a corrupt businessman building condos in the sewers until the Ninja Turtles foiled it. As payback, the businessman sent Slash to smash the Freedom Bell, which would tarnish the Turtle's reputation and give them a bad name. The Turtles eventually stopped them and sent Slash into space aboard a trash rocket, which unknowingly contained a plastic palm tree that he was so content with. After having a run-in with a race of super-intelligent aliens who hooked him up to a machine to grant him their intelligence, Slash returned to Earth with fancy weaponry and equipment of his design and planned to turn everyone into turtles to become the number 1 supreme turtle. This was foiled when Donatello tricked him into thinking that he turned the Turtles into humans to lure Slash into a rooftop fight. Thus, Slash was reverted to his low-level intelligence and launched into space once again.

In the IDW comics, Slash was introduced as Specimen 6, a snapping turtle experiment at StockGen mutated with Old Hob's DNA assigned to hunt down the Ninja Turtles and Splinter. However, his mind became unstable and gave him a savage nature, so Specimen 6 was contained in a special tank guarded by the Rock Soldiers. He was later freed due to April O'Neil's diversion to retrieve the Turtle Tracker for the Ninja Turtles. After punching one of the Rock Soldiers, he escaped from the lab into the night. From then, Slash began lurking around the city as a mindless monster injuring people and damaging their property, such as attacking Michelangelo's pizza-delivering friend Woody and leaving scratch marks on April's van. After ripping off the shirt of a thug the Turtles just apprehended, he followed them to an abandoned church and attacked them in the church basement. Though proven more powerful than the Turtles, Slash was accidentally impaled by Leonardo and left to fall into the sewers. He eventually survived the wound and was washed ashore to be woken up by Old Hob, who told him that they should work together to hunt down anyone with a connection to StockGen. Slash was shown the error of his ways when Michelangelo gave him a candy bar that he instantly fell in love with. He agreed to help the Turtles escape from one of Shredder's traps. He was an integral part of a mission to reclaim Leonardo from the Foot Clan, and developed a strong antipathy towards Hun, whom he knew as the "Dragon Man". At the mission's conclusion, he was given a new black mask by Leonardo, as well as a bladed gauntlet. Slash's life changed forever when Hob began producing new mutants, but discovered that Lindsey Baker's psychotropic compound was crucial to the process. He took a syringe of Splinter's compound-infused blood, declaring that he wanted to be a "hero" like Michelangelo. Mikey tried to reassure Slash that he himself was not even a hero and that the two of them were both still just children, but Slash injected himself anyway. After a few minutes of agonizing pain, he suddenly began to think more clearly and speak more eloquently than before. With his new intelligence, he became the co-founder of Hob's new mutant army, the Mutanimals, and was involved in Hob and Splinter's attack on the Foot Clan.

In the 2012 animated series, Slash (voiced by Corey Feldman) was introduced as Spike, a young box turtle who 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 owner'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, Spike even developed a hatred for the Ninja 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 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. After engaging his former owner, he survived the fall off the roof top and fled into the night. However, the incident left Raphael with a lasting regret. Slash was captured a few times by the Krang 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 krang. 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 krang, 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 Krang'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 Krang.

Slash appears as a boss in the video games Teenage Mutant Ninja Turtles III: The Manhattan Project, the Super NES version of Teenage Mutant Ninja Turtles: Turtles in Time and Teenage Mutant Ninja Turtles: Shredder's Revenge.

Mutagen Man[edit]

Mutagen Man is a character in the "Teenage Mutant Ninja Turtles" franchise that suffers a bizarre encounter with mutagen that exposes his internal organs and resides in a special robotic suit.

In the 1987 animated series, Mutagen Man (voiced by Rob Paulsen) was introduced as Seymour Gutz, a nerdy mailman who became dismembered after falling into a special vat of mutagen.

In the IDW comics, Mutagen Man is a failed attempt at combining several different animal breeds into one mutant. When The Mutanimals found him strapped to a bed, they tried to free him. Although he is told that he's being saved, Mutagen Man has a different idea of the term by forcing Old Hob's gun to his dome and urging him to fire. Hob refuses and they all escape the facility together. Later, Mutagen Man was given the name "Seymour Guts" by Mondo Gecko.

In the 2012 animated series, Mutagen Man (voiced by Roger Craig Smith) was introduced as Timothy, a young ineffective ice cream vendor who, after witnessing the Turtles' first battle with Baxter Stockman from his apartment window, dedicated himself into fighting crime as a wannabe superhero in a turtle costume called The Pulverizer. When he was exposed to mutagen, he dissolved into a 6-foot (1.8 m). mutant blob of mutagen with floating organs and a disintegrating touch. He kept in a special mutagen container by Donatello, who keeps him in his room in the lair and promises to help him find a way to turn back to normal.


Ninjara's real name is Umeko, but for reasons that were never fully revealed she goes by the name "Ninjara". While Splinter first thought she was an "atomic child", she was actually once part of an ancient race of humanoid foxes living on a hidden island off the coast of Japan. She ended up becoming a thief and assassin for the villainous dog-man Chien Kahn, but then had a change of heart when she met the Turtles, and fell in love with Raphael. She helped out on many missions, from the Far and the Middle East to Dimension X. Her family life was explored more in detail when her younger brother managed to track her down and convince her to come back home. The Turtles discovered the island was hidden by fog banks, but despite this, it had been discovered by an opportunistic, greedy hunter. She was a powerful member of the team from issue #29 until issue #70 from the TMNT Adventures from Archie comics.


Professor Zayton Honeycutt, also known as Dr. Zayton Honeycut, is a semi-retired scientist from the planet D'Hoonib whose mind was transferred into his working robot as both were struck by lightning. As he refused to build a transmat device (a means of teleportation) for General Blanque of the Federation military in their war against the Triceraton Republic, he was categorized as a "Fugitoid" (short for "fugitive android"). The character was introduced in a series of strips in the Gobbledygook comics that was later finished in a one-off self-titled comic book and then guest starred in the original TMNT issues 5 to 7, later became a recurring character in the main TMNT comic.

In the IDW comics, Professor Honeycutt was a Neutrino scientist who used to work for Krang. Honeycutt's wife Marra worried about the influence of evil that was oppressing the Neutrino people, including their family. She convinced him that they should join the Neutrino resistance, and so they did. Three months later, Krang's armies had found where the resistance compound was and targeted it for attack. A fire broke out, and the living quarters were locked down due to safety protocols. Rather than let Marra, their son Ely, and the rest of the families burn to death, Honeycutt used SAL to breach the flames and override the safety protocols. By doing so, he sacrificed his own body where he became trapped within SAL in the process. Honeycutt saved the families, but his victory was short-lived. Sergeant Granitor ordered an attack on the fleeing families killing them all. Honeycutt could do nothing but watch them die on the security monitor. Not long after, Honeycutt had made it back to the lab, and Granitor and some Rock Soldiers found him. Honeycutt restrained himself from tearing apart the man who gave orders to kill his family and instead escaped through the portal he had been working on. Now in New York City on Earth, Honeycutt masqueraded as a blonde male to hide from the Rock Soldiers. Honeycutt took a job with Baxter Stockman at StockGen calling himself Chet Allen. Stockman worked with Krang, so Honeycutt was hidden within plain sight. Krang referred to the professor's new form as a "fugitive android". Rather than involve more innocents in the fight, Honeycutt allied himself with the Foot Clan. Although Honeycutt knew the Foot Clan were evil, they were enemies of Krang and his forces as well.

The Fugitoid appeared in the 2003 Teenage Mutant Ninja Turtles animated series voiced by Oliver Wyman. Here his mind was transferred into the robotic body of his helper robot SAL after the pair were struck by lightning while Honeycutt was wearing a psychic amplifier device. Both the Triceratons and the Federation pursued him seeking to obtain his Teleportal device to gain the upper hand in their ongoing conflict, but Honeycutt found surprising allies in the Turtles. They wound up back on Earth courtesy of the Utroms' transmat, which later transported Honeycutt and the Utroms to their homeworld. However, upon learning that the Triceratons had pursued him to Earth, Honeycutt returned there after erasing the Teleportal blueprints from his mind. He was eventually captured by the Federation, but managed to infect their fleet with a computer virus that shut them down, with his body being fried in the process. Honeycutt's sacrifice touched both sides, and a peace soon resulted between the two. Honeycutt later returned, having uploaded a copy of his mind into Earth's satellite network prior to his demise. Leatherhead later built him a new body using Earth technology, and he would continue to provide aid to the Turtles, eventually officiating at April and Casey's wedding. He is also a playable character in the brawler game Teenage Mutant Ninja Turtles: Smash-Up for the Wii.

The Fugitoid appears in the 2012 animated series, voiced by David Tennant.[3] He first appears at the conclusion of season 3 aboard his vessel, the Ulixes, just in time to save the Turtles, April O'Neil, and Casey Jones from a black hole created by the Triceratons. After they escape, he introduces himself and promises them that they are about to embark upon a great adventure. He revealed that he was a normal scientist until his body was destroyed by the Triceratons for turning down their offer to make weapons for them. His brain survived and was placed in the body of his robotic assistant, and he set out to stop the Triceratons from causing any more harm. He also formed an alliance with the Utrom some time prior to becoming a cyborg, and later approached them with the Turtles in an effort to learn the whereabouts of the black hole generator fragments. The reason for Fugitoid's involvement was later revealed in "Earth's Last Stand": he had created the black hole generator and then sold it to the krang, only learning later the ghastly use to which it would be put. Despite the distrust this prompts in the Turtles, April, and Casey, Fugitoid manages to recover the generator and execute his plan: combining his power source and that of his ship to destroy the generator while wiping out the Triceraton fleet in the process. A past version of the Fugitoid then arrives and takes the now duplicate versions of April, Casey, and the Turtles on an adventure; meanwhile, in the wreckage of the Triceraton fleet, present-day Honeycutt's head is shown to be intact and apparently partially functional.

Despite being something of a major character, the Fugitoid makes no video game appearances.

Supporting characters and allies[edit]

Tang Shen[edit]

Tang Shen appears in the Mirage comics as the lover of Splinter’s owner Hamato Yoshi.

Then Shen appears in the IDW comics as Hamato Yoshi's wife.

In the 2003 animated series, Tang Shen debuted in flashbacks in the Season 4 episode "Tale of Master Yoshi", which was told by Leonardo to Splinter and the other Turtles. In this version, Tang Shen had been an orphan raised by the Ancient One, in Tokyo, Japan, who eventually took in the orphaned Hamato Yoshi and his friend Yukio Mashimi as his own sons. As the years passed, she fell in love with Hamato Yoshi, and took in a hungry, innocent rat as a pet. As her bond with Yoshi strengthened, an even greater rift occurred in Yoshi's longtime friendship with Mashimi. Blinded by jealously and hatred, Yukio had ruthlessly murdered Tang Shen in cold blood. Her premature demise is what prompted Hamato Yoshi to challenge his former best friend and adopted brother to a duel. It was Tang Shen's everlasting kindness, beauty and love that made him name the pet rat "Splinter". Her grave is located on a hill of flowers, where Hamato Yoshi was eventually laid to rest as well.

In the 2012 animated series, Tang Shen had been the loving wife of Hamato Yoshi (who eventually mutated into the mutant-rat Splinter), and had borne a daughter whom they named Miwa. Her decision in choosing Hamato Yoshi over his adopted brother, Oroku Saki, had caused intense hatred to fester between them. Further taken over by vengeance, jealously and rage, Oroku Saki had staged an attack on Yoshi, attempting to finish him once and for all. However, Tang Shen intervened to defend her husband; a fatal decision, as the final blow meant for Yoshi had struck her instead. Fifteen years after her tragic demise, Hamato Yoshi had moved to New York City (which had been her own desire), where he had purchased four baby turtles, encountered a krangdroid, and mutated into the rat-mutant Splinter via their mutagen. To keep her memory alive, several photographs of her remain with her husband in the Dojo, and a torn color picture (with her shoulder held by her husband Hamato Yoshi, who the Shredder had torn off to further make his fabrications more real) kept by her teenage daughter Miwa, who had been abducted by Oroku Saki as an infant and renamed Karai. She is even seen in memories of Splinter's. She makes her first and only live appearance in "Tale of the Yokai" when the Turtles travel back sixteen years previously via Renet's time specter. She had expressed her dislike at her husband wanting to save the last of the Hamato clan, as she believed ninjas had no place in the modern world, not wanting her only child to follow in the path of her father. She was later approached by Oroku Saki, now clad in Foot Clan attire, and said that she had made her choice. She was asked to take little Miwa and leave as the two adopted brothers faced off in a death-duel. In the prequel episode "Lone Rat and Cub" Tang Shen was seen in the black-and-white picture of her next to her husband, holding their baby daughter between them. She was last seen in a vision of Splinter's when he debated whether he had the discipline to be a proper father, for either Miwa (were she alive) or the baby mutant Turtles.

Mr. O'Neil[edit]

There have been different versions of April's father in the TMNT franchise.

In the Mirage Comics, he is named Robert O'Neil. Not much is known of O'Neil, only that he is an antique dealer who owned his own shop, "Second Time Around", and a proficient businessman. One day his daughter Robyn was born, but his wife could no longer bear any children. In his examination of a few things that he purchased, but had not yet sorted, he had found a strange crystal, O'Neil attached the crystal to a pencil and was miraculously able to bring his drawings to life. O'Neil decided to satisfy his wife's desire to have children, but all of his attempts to create babies broke into nothing, as he had drawn them with a pencil. Sometime later O'Neil tried again with an ink pen, the result did not disappear this time and grew into a young woman: April.

Nearly thirty years later O'Neil died of a serious illness (probably cancer) and bequeathed his entire estate to his daughters, he gave April his old antique shop (but by then it was already destroyed by the Shredder and the Foot Clan when they had sought vengeance on April's new friends, the Turtles). All his life he had the secret of her origin concealed from April, until she had to learn through a chain of dramatic circumstances that she was not a naturally-born creature, and only some time later with Renet's Help was she finally able to discover the truth. This realization gave April a severe emotional crisis, and she left her old life behind for a while to find a new meaning to her existence.

In the 2012 animated series, he is named Kirby O'Neil, voiced by Keith Silverstein. In this show, Dr. Kirby is a psychologist, but was mutated into a mutant bat in the season 2 premiere "The Mutation Situation" and coined "Kirby Bat" until he was cured in season 3's "Battle for New York".

In the IDW Comics, April's father is named John O'Neil. John experienced a stroke that left him wheelchair-bound and reliant on his wife Elizabeth. Their daughter April considered abandoning her studies to help look after him, but her parents argued against it. Up until his stroke, John was employed as chief assistant at StockGen, the genetics laboratory of Baxter Stockman, which is responsible for the transformation of Splinter and the Turtles into mutants. He also knew of the Ooze, the base material for Stockman's experiments. It was through his initiative that April was able to secure her internship, through which she later became acquainted with the Turtles, but he and his wife already had a hunch that something in this laboratory was not right.

Some time later, the Turtles were traced by agents of the Foot Clan to the O'Neil Farm, while Elizabeth learned of the Turtles in a very dramatic way. After April and Splinter had declared her necessary, Elizabeth received from her daughter a vial of Ooze, which she used to heal her husband from the effects of his stroke. Then they returned to New York to be closer to their daughter, and opened their old antique shop again. They later invited Casey to live with and work for them there, which attracted the ire of Hun. Fortunately, their neighbors on the same street came out to assist the O'Neils, and peace was restored. During the Triceraton invasion, John and Elizabeth remained in the Second Time Around store for some days, anxious about April's safety. Eventually April and Baxter Stockman brought them to the T.C.R.I. building, where John and Elizabeth were reunited with their daughter.

In the 2014 film, April's father was referred to as Dr. O'Neil and was portrayed by Paul Fitzgerald. He was a scientist working at Sacks Groups Ltd as one of the creators of the TCRI mutagen. Splinter was the one who informed April that her father was killed by Eric Sacks and the Shredder destroying their lab.

Mrs. O'Neil[edit]

There have been different versions of Mrs. O'Neil in the TMNT franchise.

In the Mirage Comics, she was named Bridget O'Neil.

In the 2012 animated series, Mrs. O'Neil (voiced by Renae Jacobs) was the loving wife of the psychologist Kirby O'Neil, and the late mother of sixteen-year-old April O'Neil. Many decades ago, when she herself was a child, her grandfather had discovered the Krang residing deep underneath the O'Neil's family farmhouse. After unmistakably awakening the Krang, the brain-like extraterrestrial creatures paid him back by performing experiments on him and his entire bloodline; including Mrs. O'Neil. In her adult years she had fall in love with and married an Irish scientist by the name of Kirby O'Neil. She was eventually captured and experimented on by the Krang while she was pregnant with April. As a result, her daughter was born a human/Krang hybrid mutant; possessing an array of exceptionally powerful psychic abilities, as a result of her Krang DNA. When April was six years old, the Krang came for her. While her husband was able to escape to New York City, Mrs. O'Neil was recaptured and "put into stasis." One decade later (in Episode 55 "Buried Secrets"), she was discovered by the Turtles, Casey Jones, and her teenage daughter. She explained how her whole family's difficulties with the Krang raged on for many years, and seemed happy to be reunited with her daughter. She wondered of Kirby's whereabouts, to which the Turtles assured her that he was "on a safari in Puerto Rico." She attracted the suspicions of the sharp and intuitive Michelangelo, who planned to expose her true motives by any means. She was later revealed to be a clone of the real Mrs. O'Neil as an infiltration experiment infused with the human DNA of the real Mrs. O'Neil and Krang DNA; thus having only her memories. April expressed her sadness at losing her family all over again, even if it truly was not her mother, and wondered if she was indeed gone forever or was still alive somewhere. A family photograph of her, alongside her husband and infant daughter, was shown in "The Krang Conspiracy" which had been kept by Jack Kurtzman. She was first referenced by April in "Karai's Vendetta". April mentioning the tragic loss of her mother as a child, caused Karai to feel sympathy for April, as she, too had lost and never knew her own mother, Tang Shen.

In the IDW Comics, April's mother was named Elizabeth O'Neil, who was a journalist (similar to April's status as a reporter from various TMNT media adaptations). Elizabeth was first introduced when April, the Turtles, Casey, and Splinter were forced to flee New York to their home in Northampton. While April and Casey worked on keeping the Turtles and Splinter a secret, Elizabeth showed having some knowledge of the mutagen due to her past career as a reporter. When the Foot Clan tracked them down and attacked Elizabeth along with her husband John found out about the existence of the Turtles and Splinter. After the group fled, Elizabeth used a part of the mutagen April left behind to help heal John from his stroke due to its healing properties. Afterwards, the two moved to New York and took up residence in the Second Time Around store, where they maintain a good relationship with their daughter and her other friends, where they also allowed Casey to stay with them due to issues he has with his father.

Justice Force[edit]

The Justice Force is a superhero team that was around during the Golden Age.

First appearing in the Mirage Comics issue "Dome Doom", the Turtles and Casey meet the older versions of the Justice Force in Northampton at the time when their former member Doctor Dome attacked them with his Domeoids. The fight ended when Battlin' Bernice's daughter named Ananda showed up to chastise Doctor Dome for ruining her mother's life. Stainless Steel Steve broke up the argument and offered Doctor Dome a redemption which he took. When Lilith swore vengeance on Shadow Jones for the death of Sloan, April and Casey asked Stainless Steel Steve and Metal Head to help Splinter watch over their stepdaughter.

In the 2003 TV series, the Justice Force first appears in the episode "Return of the Justice Force". The Turtles and Casey head to Northampton where they enter Steve's comic book store to look for a lost issue that would've helped Michelangelo know the fate of Battlin' Bernice. They meet the Justice Force when Doctor Dome started using his Domeoids to abduct them. It was soon discovered that Doctor Dome's secret daughter with Battlin' Bernice named Ananda was behind this where she wanted revenge on the Justice Force for letting her mother die. When Ananda was defeated, Doctor Dome reconciled with his daughter and also reconciled with Stainless Steve Steel. In later episodes, Ananda and Metal Head formed a second incarnation of the Justice Force that consisted of Silver Sentry, Chryalis, and Tsunami with Stainless Steel Steve in an advisor role and Zippy Lad training the new recruits. Their membership was later expanded with Nobody, Raptarr, and Nano in the episode "Membership Drive" while also gaining Michelangelo as the Turtle Titan. The Justice Force are among the allies of the Turtles who assist them in the fight against the Demon Shredder's forces. The episode "Super Power Struggle" revealed another former member called the Green Mantle who lost his powered cape in a battle and was found by Raphael during the fight with Dr. Malignus. When Dr. Malignus was defeated, the security guard at the convention turned out to be Green Mantle's true identity of Al Gordon who reclaims the special cape and rejoins the Justice Force. The Justice Force are among those who attended April and Casey's wedding and helped to fight the Cyber-Shredder.

Stainless Steel Steve[edit]

Stainless Steel Steve is the leader of the Justice Force who gets his name from the round metallic saucer on his head which can smash through anything.

In Mirage Comics, Stainless Steel Steve and Doctor Dome competed for the love of Battlin' Bernice.

When Ananda came into view and broke up the fight, Stainless Steel Steve offered Doctor Dome a chance at redemption.

Stainless Steel Steve appears in the 2003 animated series voiced by David Wills impersonating Adam West. During the Justice Force's fight with Doctor Dome, Michelangelo mentioned that Stainless Steel Steve once saved Doctor Dome from the Living Volcano and Doctor Dome once cured Stainless Steel Steve of the creeping alien rust. When Ananda was defeated and had reconciled with Doctor Dome, Stainless Steel Steve thanked the Turtles and Casey Jones for their help and even made Michelangelo an honorary member of the Justice Force. In "Super Power Struggle", Stainless Steel Steve appeared in an advisor role to the second incarnation of the Justice Force at the time when Raphael found the Green Mantle's powered cape. Following Dr. Malignus' defeat, Stainless Steel Steve picked up Al Gordon from the hospital and reunited with the Justice Force while reclaiming his cape.

In Mirage Comics, he and Stainless Steel Steve competed for the love of Battlin' Bernice. When the Justice Force disbanded, Doctor Dome had a falling out with them. Years later, Doctor Dome started targeting the Justice Foce members to draw out Battlin' Bernice which also brought him into conflict with the Turtles and Casey Jones. When Battlin' Bernice's daughter Ananda shows up to break up the fight, she chasitizes him. Stainless Steel Steve offered Doctor Dome a chance at redemption which he accepted.

Doctor Dome appears in the 2003 animated series, voiced by Stuart Zagnit. He was suspected of being behind the abductions of the Justice Force when they arrived in his lair. When Doctor Dome clashed with Stainless Steel Steve where he blamed him for what happened to Battlin' Bernice, Michelangelo tried to get them to remember the times when they worked together like when Stainless Steel Steve once saved Doctor Dome from the Living Volcano and Doctor Dome once cured Stainless Steel Steve from the creeping alien rust. It is then discovered that Doctor Dome's secret daughter Ananda was behind this where she wanted revenge on the Justice Force for letting her mother die. The Turtles threw off Ananda's concentration on the Domeoids to defeat her. Doctor Dome then reconciled with Ananda. Michelangelo recapped to Joey Lastic that the strategy to defeat Ananda was the same one the Justice Force used to defeat the Grim Repo in issue #57 when he gained control of Doctor Dome's brain.

Punk Frogs[edit]

The Punk Frogs are a group of mutant frogs who are the counterparts of the Ninja Turtles.

In the 1987 series, the Punk Frogs are created by Shredder when mutagen landed in their part of the swamp. Shredder convinced them that he was a good guy and to be his warriors where he named them after would-be conquerors and dictators. Shredder trained them to fight the Turtles whom he had convinced the frogs into believing were bad guys. Each of the frogs were named after Shredder's own "heroes". After the Turtles saved them from being captured by Captain Hoffman, they realized that the Turtles were good guys and that the Shredder was a bad guy and broke ties with him. Afterward, the frogs became friends with the Turtles, with Attila emerging as the group's leader. They may even be described as having the character traits of the Ninja Turtles.

In Ninja Turtles: Superman Legend the Punk Frogs (except Napoleon Bonafrog) make a cameo.

In the 2012 series, the Punk Frogs were created by mutagen poured into their pond near the O'Neil family farmhouse by Mrs. O'Neil's Krang clone. Besides Attila, Genghis, Napoleon, and Rasputin, there are a substantial number of Frog Soldiers working for them. Evidently remembering the actions of humans in destroying their swamps to make room for cities, they swore revenge upon them, and briefly considered the Turtles brothers in need of liberation until learning that they were friends with April and Casey. Afterwards, the Punk Frogs

In the comic series published by IDW, the Punk Frogs are a faction in Mutant Town ever since Old Hob's mutagen bomb went off in a part of New York City. Besides Atilla, Genghis, Napoleon, and Rasputin, there are other members of the group consisting of Bloody Mary, Bonnie, Clyde, and Zetian. The Turtles came into conflict with them when the Punk Frogs thought that one of the Turtles kidnapped Bonnie. When the Turtles claimed that they didn't do it during the attack, they also claimed that it must've been some other mutant turtle that was the culprit. Clyde and the Turtles find that Dr. Jasper Barlow cobbled Bonnie together with a prosthetic shell that was implanted with a dragon scale and other turtle-like parts where he called her "Venus". After Dr. Barlow was thwarted, Clyde took Bonnie's original arms back to the Punk Frogs where he informed them that Bonnie is "dead" and that the Turtles weren't responsible.

In the 2012 animated series, Napoleon Bonafrog (voiced by Jon Heder) is depicted as a clumsy frog disliked by his brethren, which leads to his befriending Michelangelo. Much of his behavior was a nod to Heder's character in Napoleon Dynamite.

In the IDW comics, Napoleon is a tall and well-built member of the Punk Frogs and wields a whip.

Renet Tilley[edit]

Renet Tilley is a rather reluctant, spoiled, and impulsive teenager whose parents, also denizens of the 79th Level, hoped that apprenticing her to Lord Simultaneous would help her develop some kind of common sense. Curious and impatient as she was, she did not care very much for studying. Renet first met the Turtles fooling around, when one day out of boredom she snatched her master's Time Scepter and was caught by him. She replied immediately and time-traveled off with Lord Simultaneous' Sceptre of the Sands of Time to Earth – more specifically to 1986 New York City. Renet and the Turtles became friends, but Simultaneous appeared and sent Renet into a panic. Fleeing Simultaneous further, she and the Turtles went to 1406 A.D., straight into a castle siege. The castle belonged to the dark mage Savanti Romero, a former, but exiled student of Simultaneous, and the besiegers were the soldiers of Cerebus, who was after some scrolls, that Romero had stolen. Romero also managed to grab the Time Scepter, and the Turtles and Renet had to contend with Cerebus' help to attack the castle and get the Sceptre back from Savanti Romero. The force was no match for Romero's magic. Before it came to the worst, Simultaneous appeared. Romero attacked Lord Simultaneous who took the Time Scepter again and cast Savanti into prehistoric times. He handed the scrolls to Cerebus, sent the Turtles back again to their time, and sent Renet to wipe dust in his huge library. Later, she assists the Turtles in defeating Savanti Romero in prehistory when Romero plans to alter the Earths orbit and prevent the asteroid impact that wiped out the dinosaurs, meaning humanity, and mutant Turtles, will never exist. After defeating Romero, the group is stranded in prehistory for several months after the Scepter is lost in the ocean, but it is eventually recovered. Renet makes a third appearance saving the Turtles from Romero's demonic bride, Juliet Romero. This time she appears as a deity-like woman with full control over her time manipulating powers.

In the 2003 animated series, Renet (voiced by Liza Jacqueline) undergone some minor changes in her backstory, where she is shown to be quite a scatterbrained person who came to her friends with good intentions, but with little practical skill she caused some problems across space and time. This leads to her transporting herself and the Turtles back to the medieval age to which Savanti Romero was banished, which resulted in the loss of the Time Scepter to Ultimate Drako, the fused form of the Ultimate Ninja and Drako. It would later be recovered and entrusted to Renet again, leading to another encounter with Romero in the Cretaceous Period. She would later appear at April and Casey's wedding, watching from a distance.

In the IDW comics, Renet has her debut in a special story, where she "invites" the Turtles to the interdimensional Battle Nexus tournament. In this version she is also Lord Simultaneous' pupil in magic, dimension travel, and apparently his successor in the Dimensional Council. At the time in which she appears for the first time, the cruel Councilor Nieli hosted a series of merciless gladiator fights, which only he really liked. Renet was also against the games for personal motives, because one of the champions, the warrior Baltizar, had won her heart. For this reason, they brought the Turtles to the hub of the dimensions and helped the culmination of these events to instigate an uprising against Nieli which meant that Nieli was banished and the games were transformed into a far more peaceful affair.

In the 3D CG 2012 animated series, Renet (voiced by Ashley Johnson) is a young immature timestress from the future who, like Michelangelo, makes rash decisions that sometimes gets her and others into trouble. She is also becomes the object of Michelangelo's affections. After taking her master's time scepter to keep it out of the hands of mutant time master Savanti Romero, she traveled back in time to get help from the Ninja Turtles. She ended up banishing Savanti to the Middle Ages, but was forced to pursue him to preserve history. This eventually got Renet and the Turtles to lose the scepter to Savanti, but after a series of conflicts, they recovered it. However, while traveling them back to their present, she lost the Turtles to sixteen-years-prior Tokyo, Japan, due to the mystical time scepter taking matters into its own hands. After six months from her perspective, she was able to locate them and return them to the twenty-first century. In the fifth and final season of the show, "When Wolds Collide, Part One" a hologram of her is first seen in Michelangelo's room. She appears to still keep in touch with the Turtles, particularly Mikey, who still has a crush on her. In the Monstrous Tales saga (consisting of four episodes "The Curse of Savanti Romero", "The Crypt of Dracula", "The Frankenstein Experiment" and "Monsters Among Us!") Renet returns to 21st century New York City, once again needing the Ninja Turtles help in stopping her Savanti Romero from making an unbeatable army of the undead by traveling back to the ancient past, to the time when Dr. Frankenstein began his monstrous scientific experiments.


Tattoo is a sumo wrestler whose tattoos can be used as weapons.

In the Teenage Mutant Ninja Turtles episode "Planet of the Turtleloids" Pt. 1, Tattoo (voiced by Rob Paulsen) was not a human being at all but a hamster mutated by the Shredder into human form. The Ninja Turtles encounter him vandalizing a pet shop. After a scuffle in which a confused angered Tattoo wraps himself up in electrical wire, he is electrocuted and reverted into hamster form. Leonardo deduces that Shredder kidnapped the hamster from that very same pet store and all he wanted was to return home.

In the Archie Comics he asked Splinter for a favor and requested that the TMNT rescue his chihuahua dog "Inky" from a group of Yakuza who wanted him to throw his next fight for gambling purposes. Tattoo states that he can't lose the match as it will ruin his career. The TMNT vow to help him get his pooch back without having to throw the match. While Tattoo is engaged in his Sumo match, the TMNT, Ninjara and the Warrior Dragon infiltrate the mob headquarters and rescue the feisty pup. Tattoo wins his match and the Turtles return Inky to his beloved master. The wrestler awards Leonardo a katana as thanks for saving his dog.

Alopex is a mutant arctic fox who debuted in the IDW comics. Originally a normal arctic fox in Alaska, she was captured by scientists and taken away from her family to be experimented on with mutagen, granting her human-like intelligence and altering her body. She was rescued from the laboratory by Shredder and recruited into the Foot Clan, whom she loyally served for years. In her first appearance in Teenage Mutant Ninja Turtles: Micro-Series, she attempts to trick Raphael into bringing her to their lair, but he manages to catch onto her scheme.[4]

Shredder later tested her commitment to the Foot by burning down the forest she grew up in. While she continued serving him, she vowed to kill him one day. She ultimately defects to the Turtles' side when they fought the Shredder to reclaim a brainwashed Leonardo from him. While their relationship with her is tense at first after she follows them to April's parents' farm, she ultimately gains their trust thanks to Leonardo vouching for her and bonds with Raphael. After Splinter kills Shredder and takes over the Foot Clan, she helps train the new recruits and forms a close friendship with Angel aka Nobody.

However, she is brainwashed by Kitsune into an assassination attempt on Splinter. Though it's successfully prevented, she runs back to Alaska to fight of Kitsune's influence, and with help from Raphael and Angel, she's able to rid herself of it completely. She returns home and begins dating Raphael while helping the Turtles monitor Mutant Town as part of the Splinter Clan (even getting her own green mask in the process), but she later separates from them when they decide to work together with Shredder to prepare for the Rat King's Armageddon Game[5] and adopts Old Hob's mutated weasels to form the Claw Clan.

Alopex appears in the 2012 series voiced by Minae Noji. This version is a mutant red fox who possesses superhuman speed and the sister of recurring series villain Tiger Claw. When she and her brother were children in Japan, they wandered into a portal on a playground and ended up getting captured by the Kraang, who mutated and experimented on them for months. When they eventually escaped, they ran away from home knowing the rest of their village would see them as monsters, joining a circus and later becoming top-level assassins. Alopex developed a vendetta against her brother for forcing her into a life of crime and murdering their parents and rebelled against him, cutting off his tail in the process. In "Tale of Tiger Claw", she comes to New York to finish her brother off and steals the Cursed Blades of Vengeance to do so, accidentally cursing Casey Jones in the process.

Tatsu is a Foot Clan Warrior and the Shredder's second-in-command in Teenage Mutant Ninja Turtles, Teenage Mutant Ninja Turtles II: The Secret of the Ooze, and the 2012 animated series.

In the films, Tatsu (portrayed by Toshishiro Obata, voiced by Michael McConnohie) is a skilled martial artist who oversees the training of Shredder's army. He rarely speaks except to Shredder or to give orders to the Foot Ninja or those training to join the ranks. He leads the attack on April O'Neil's home in the first film, and later fights with Casey Jones at the Foot lair. Though initially overpowering the vigilante, he is defeated after Casey finds a golf club among the various stolen items stockpiled by the Foot and uses it to subdue Tatsu. In the second film, he is shown to have escaped police custody, and attempts to take leadership of the Foot until the Shredder is revealed to be still alive. He leads the Foot Ninja who steal the mutagen from TGRI, and helps oversee the rebuilding of the Foot army. However, he is easily defeated near the end of the film by the Turtles all slamming their back shells into him.

Tokka and Rahzar[edit]

Tokka and Rahzar are a mutant alligator snapping turtle and gray wolf employed by Shredder and enemies of the Ninja Turtles.

Tokka and Rahzar first appear in Teenage Mutant Ninja Turtles II: The Secret of the Ooze with Tokka face-performed by Rick Lyon, in-suit performed by Kurt Bryant, and voiced by Frank Welker while Rahzar is face-performed by Gord Robertson, in-suit performed by Mark Ginther, and also voiced by Frank Welker. As a snapping turtle and gray wolf abducted from the Bronx Zoo by the Foot Clan, Tokka and Rahzar were mutated into more intelligent humanoid forms by kidnapped TCRI professor Jordan Perry under Shredder's orders, but during the process, Perry secretly altered the mutagen with the DNA of human children. This eventually gave the duo childish personalities, thus humiliating Shredder by thinking the word "master" meant "mama". However, Perry had sympathy for them and showed Shredder their full obedience, thus convincing to keep them around. The duo even proved to be more than a match for the Ninja Turtles. After failing to stop them from rescuing Perry, Shredder had them cause destruction to an old neighborhood. The next day, Shredder had the Foot encounter April and have her deliver the Turtles a message telling them to meet the Foot Clan at a construction site near the docks or else Tokka and Rahzar will be sent out again. This time, they will be sent into Central Park. The Turtles note that Tokka and Rahzar won't avoid any people there. Perry had prepared a retro-mutagen for the Turtles to use, which retro-mutated both Tokka and Rahzar after a brief battle during a Vanilla Ice concert. The fate that followed the duo's retro-mutation remained unknown, but it's most likely that they could've been carted back to the zoo.

In the 1987 animated series, Tokka (voiced by Rob Paulsen) and Rahzar (voiced by Townsend Coleman) were out-of-control alligator snapping turtle and gray wolf zoo exhibits mutated into their current mutant forms when Shredder infected their habitats. Following their first encounter with the Ninja Turtles at the Crystal Palace Mall, Tokka was captured by a mutant hunter and taken to Dirk Savage, leaving Rahzar to report back to Shredder. Rahzar made a big deal with Tokka's capture and went to fight Dirk alone, yet it was unclear of whether or not the duo was reunited following the rescue mission.

In the series finale of the 2003 animated series titled "Turtles Forever", two Cyber Foot members are mutated into the 2003 incarnations of the characters and play a brief role as members of the Mutant Foot Soldiers.

In the 2012 animated series, Tokka (vocal effects provided by different sound effects) and Rahzar (voiced by Clancy Brown) are given drastically different origins. As a result, they were never seen together in this series.

Rahzar is introduced first as Chris Bradford, a celebrity martial arts star who is a prized pupil of Shredder, owning chain of dojos across the country with their ninjutsu classes used for the purpose of recruiting Foot Ninjas. When Shredder learned of Splinter's presence in New York, he sent by Bradford to find and kill both him and the Ninja 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 he failed to trick the Turtles into leading him and the Foot to Splinter and numerous repeated failures, Shredder became enraged at his incompetence. During a fight with the Turtles, Bradford and Xever were doused with mutagen, and as a result of being earlier 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 simply dubbed Dogpound. However, he hated his larger, clumsier form. Dogpound was later mutated into a near-skeletal werewolf-like version of his previous form with more agility, which he found more acceptable. Being given the new name Rahzar by Michelangelo, he continued to serve the Shredder until his death at the hands of Leatherhead towards the end of the fourth season. Rahzar was resurrected by the demon Kavaxas in the fifth season, only to be revealed to be serving as Kavaxas's puppet. Rahzar fell into the Netherworld during Kavaxas's attack on the mortal realm, never to return.
Tokka, on the other hand, is introduced as Tokka Picasso, a monstrous female turtle-like alien assigned by the Utroms to guard the final piece of the Black Hole Generator. In her first appearance, she attempts to recover the Black Hole Generator piece from when Lord Dregg was able to steal it. However, the piece was seemingly destroyed by the explosion of a dwarf star triggered by the Triceratons, though Tokka's son Chompy survived and remained with the Turtles. Tokka subsequently was revealed to have survived the ordeal and ventured to Earth to collect her son but decided to allow him to stay with Raphael after realizing he was in good hands with him. Tokka departed Earth, though Raphael conceded that one-day Chompy would have to return to the stars with his mother.

In the comic series published by IDW, Tokka and Rahzar appear as two of Old Hob's mutant creations. He was to sell them as "recruits" to Karai and the Foot Clan.[6]

The Shredder Clones are the Clones of the Shredder. They consist of:

  • Claw Shredder – A clone of Shredder with crustacean-like claws.
  • Mini-Shredder – A small clone with a wrist blade on each arm.
  • Shiva Shredder – A hulking brute with four arms.

The Shredder Clones first appeared in the Mirage Comics. Shredder claims that they were created through a combination of ancient magic, modern science, and a Paramecia Coloniex (a species of colony worms created by the Foot Clan) where they turned the remains of someone into a replica of said person while claiming that the Paramecia Coloniex fed on Oroku Saki's charred remains

The Shredder Clones appear in the 2003 animated series. They were referred to as Mutant Shredder Clones where they were kept in liquid vats within the Foot Clan's headquarters. They resembled the Shredder more where the Claw Shredder was less crustacean-like. The Turtles and Splinter fought them where the Claw Shredder was emerging from the rubble and the Mini-Shredder and Shiva Shredder were last seen on top of a falling elevator. Their fates after that were unknown.

The Shredder Clones appear in the 2012 series, voiced by Kevin Michael Richardson. They were referred to as the Shredder Mutants where they were created by Baxter Stockman through a combination of Shredder's DNA and different crustaceans. They are first seen in "Return to New York" where they served as the guards to Stockman-Fly's laboratory. The Turtles fought them and Stockman-Fly during a mission to rescue Splinter. Once Splinter regained his mind, he defeated the Shredder Mutants by knocking them towards the fan beneath the mutation device. In "Attack of the Mega Shredder", Leonardo and Michelangelo sneak into Stockman-Fly's lab to obtain some Brain Worms and are caught by Rocksteady, Bebop, and the Shredder Mutants. When Rocksteady and Bebop planned to mutate the Turtles, Leonardo states that they should mutate more animals. This causes Rocksteady and Bebop to dump the Shredder Mutants into the mutagen vat which fused them into a gigantic blob-like super-mutant dubbed Mega-Shredder as it goes on a rampage in New York. When the Mega-Shredder's young Oroku Saki-like tongue was cut off by the Turtles due to it serving as the brain, the Mega-Shredder dies.


Krang is an alien warlord that comes from Dimension X in several incarnations of the series. The 1987 animated series featured him as disembodied brain, others as a rogue Utrom, such as the TMNT comic strips and the IDW comics.

In the 2012 series, Krang is referred to as Kraang Prime, and is the leader of a rogue hive mind faction of Utroms known as "the Kraang".

In Teenage Mutant Ninja Turtles: Mutant Mayhem, a woman named Cynthia Utrom is in charge of TCRI. Her surname and connection with Shredder (which is implied in the post credits scene) suggest that she may be revealed to be Krang in the future sequel.

Rock Soldiers[edit]

The Rock Soldiers (sometimes called Stone Warriors) are sentient humanoids that are made from rocks.

In the 1987 cartoon, the Rock Soldiers work for Krang and come from Dimension X. It was revealed in "Michelangelo's Birthday" that they were made when Mutagen fell on some rocks. Different voice actors voiced the generic Rock Soldiers: Rob Paulsen and Peter Renaday.

The Archie Comics version of the Rock Soldiers are the same. It also features the exclusive Rock Soldier Morg.

In the IDW comics, the Rock Soldiers were created by General Krang.

In the 2012 cartoon, the Rock Soldiers work for the Kraang.

General Traag[edit]

General Traag is the leader of Krang's loyal Rock Soldiers from Dimension X.

In the 1987 cartoon, Traag (voiced by Peter Renaday) came following the Neutrinos through the dimensional portal. After a small skirmish with the turtles, the Neutrinos teamed up with them and Michelangelo and Donatello sent both Traag and Granitor back through the portal and to their own dimension. Traag would make further appearances in the series until the eight season finale "Turtle Trek". As "Turtle Trek" ended with the Technodrome stranded in Dimension X, it can be assumed Tragg is still in Dimension X somewhere.

He appeared in Archie Comics arcade game, and Teenage Mutant Ninja Turtles II: Back from the Sewers.

In the IDW comics, he is called "Captain Tragg" and helped Krang in trying to conquer the home planet of the Neutrinos and completely escaped after the battle in which the END rocket from Professor Honeycutt put all of the weapons of Krang's forces out of action.

In the 2012 cartoon, Traag is a 20 ft lava-spewing rock monster 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. Traag and Granitor alongside smaller Rock Soldiers were later summoned by the 80's Shredder and the 80's Kraang to attack New York where they fought the Ninja Turtles and the Mighty Mutanimals. With help from the local Rocksteady and Bebop, the Ninja Turtles sent the Rock Soldiers back to Dimension X and defeated the 80's Shredder and the 80's Krang.

Sergeant Granitor[edit]

Sergeant Granitor is General Traag's right-hand man and one of Krang's loyal Rock Soldiers from Dimension X.

In the 1987 cartoon, Granitor (voiced by Pat Fraley) came to Earth following the Neutrinos through the dimensional portal, originally appearing inside the Technodrome. After a small skirmish with the turtles, where the turtles destroyed the rock warrior's weather-making machine, the Neutrinos teamed up with them and Michelangelo and Donatello sent both Granitor and General Tragg back through the portal and to Dimension X.

He appeared in the arcade game as the 4th scene's (7th stage) boss, and Teenage Mutant Ninja Turtles II: Back from the Sewers.

In the IDW comics, he is called "Sergeant Granitor" and commanded an assault on a Neutrino resistance bunker, to capture the Fugitoid and bring him back to Krang. Due to Granitor's command, the Neutrino bunker was destroyed and many innocent Neutrinos killed along with Fugitoid's family. Later on he and several other Rock Soldiers was searching the demolished base for Fugitoid. Granitor realized that the Fugitoid was in fact Honeycutt and chased him through a portal to Earth. However, the Fugitoid used his morphing abilities to shapeshift himself into human form and get lost in the crowd.

In the 2012 cartoon, Granitor is a 20 ft blue fire-spewing rock monster 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. Traag and Granitor alongside smaller Rock Soldiers were later summoned by the 80's Shredder and the 80's Kraang to attack New York where they fought the Ninja Turtles and the Mighty Mutanimals. With help from the local Rocksteady and Bebop, the Ninja Turtles sent the Rock Soldiers back to Dimension X and defeated the 80's Shredder and the 80's Krang.

Baxter Stockman[edit]

Baxter Stockman is a mad scientist and human enemy of the Ninja Turtles, becoming employed by Shredder in most incarnations.

In the Mirage era, after creating the MOUSERS, with April O'Neil as his computer programmer, Stockman used them to commit strange bank robberies by allowing them to dig small tunnels leading into the vaults. April found out and tried to escape through the MOUSER factory elevator, but Stockman sent the elevator (with her still in it) down to the sewer level, where a squadron of MOUSERS were waiting to capture her. The Ninja Turtles saved her and successfully infiltrated the factory, stopping Stockman and leaving him in police custody. However, he escaped some time later and began using technology from DARPA to build a robot body for him to install his own brain into, making him a cyborg. Stockman tried getting revenge on the Turtles, but his new body was electrocuted and seemingly destroyed. Only his glasses remained.

In the 1987 animated series, Stockman (voiced by Pat Fraley) was a misguided Caucasian inventor who tried building his MOUSERS for the Ajax Pest Control company, but was told that it would only run them out of business and was kicked out of the building. Watching the whole scene through security cameras, Shredder approached him, offering an even better job, which Stockman accepted. Shredder had Stockman create a master control device for the MOUSERS so that the Foot Clan could use them to destroy the Ninja Turtles. However, the Turtles destroyed these MOUSERS and found Stockman's name on one of them, thus leading them to confront him and escape in his van (which later became the Turtle Van). Though he was defeated and committed to an asylum, Stockman was later freed by Shredder when Krang withdrew Bebop and Rocksteady to Dimension X. Following various incidents made by the Turtles during his service in the Foot that all ended with him getting abused by Shredder, Stockman was tasked to accompany Bebop and Rocksteady through an unstable portal to Dimension X to meet with Krang. Krang saw no use in his scientific expertise and decided to kill him by tossing him into a mutagen-powered disintegration chamber, which instead mutated Stockman into a mutant housefly due to letting a housefly land on his clothes and get tossed into the unit with him. Krang informed Shredder about what happened to Stockman. Blaming the Turtles and Shredder, Stockman fled Dimension X to take his revenge but was convinced by Shredder that the Turtles alone were responsible for his mutation and took him back to the clan, promising to have him retro-mutated once they have the Turtles pay.

In the 2003 animated series, Stockman runs a wealthy corporation on behalf of the Shredder, but when he begins failing his master due to the intervention of the Turtles, Stockman begins suffering brutal mutilation and torture at the hands of Hun as punishment. At the end of season 1, Stockman makes a play to kill Shredder and the Turtles, but is defeated when his enemies team up. Stockman is forced to rejoin the Shredder only to turn on him again early into Season 2. Stockman joins the New York mafia during the power vacuum after the Shredder's apparent death, but is conscripted once again and is tortured so severely that he is reduced to a brain and an eyeball attached to his spinal cord in a jar. During season 3, Stockman forms an uneasy alliance with Hun who has also been feeling the Shredder's wrath after too many failures, but decides to defect Agent Bishop's Earth Protection Force. In Season 4, Stockman attempts to create a clone body for himself, but the body deteriorates and he subsequently dies after an encounter with the Turtles. However, Bishop resurrects him from the dead, much to his dismay. Stockman remained with Bishop until decades after the end of Season 7, in which he was presumably killed in a lab accident. Stockman survived until the year 2105 when he tried to take revenge on Bishop, who was now the president of Earth. However, he was convinced by the reformed Bishop as well as the Turtles, who had been transported into the future, to stand down and make peace. Bishop promised to help Stockman finally regain a healthy human body.

In the IDW comics, Stockman is the head of the StockGen company that created the Turtles and Splinter, who was tasked by Krang to experiment on mutagen. He would later become the Mayor of New York City.

In the 2012 animated series, Stockman (voiced by Phil LaMarr) was a child prodigy who was constantly bullied growing up. After several encounters with the Turtles, Stockman finds himself forcibly conscripted into the Foot Clan. Despite managing to flee on his own for a time, he is brought back in by Dogpound and threatened with being mutated should he step out of line. Shredder later goes through with mutating him into a fly after deeming his work unsatisfactory, and the mutation destroys much of Stockman's sanity. Stockman has no choice but to swear loyalty to the Foot Clan. Stockman begins receiving more civil treatment from the Shredder as he begins serving full-time as his chief scientist, engineer, and medical officer. In his last appearance during the season 4 finale, the Turtles spare Stockman's life during their assault on the Shredder's compound. Michelangelo uses retro-mutagen on him, turning him back into a human. However, Stockman is furious upon regaining his humanity, insisting he was stronger as a mutant.

In the 2014 film, Baxter Stockman (portrayed by K. Todd Freeman) appears briefly in a scene as one of Eric Sacks' scientists at TCRI. The role was later recast to Tyler Perry in Teenage Mutant Ninja Turtles: Out of the Shadows.[7] Although a prominent industrialist and a genius who graduated MIT at 15, he is soon revealed to be working with the Foot Clan, using salvaged alien technology to rescue Shredder from jail by teleporting him away during a prison transport. Upon Shredder testing the purple mutagen on Bebop and Rocksteady, he notes that it taps into dormant animal DNA in their system from a point before life on Earth began to evolve in different routes causing them to mutate into a humanoid common warthog and black rhinoceros. When Shredder learns that the component Stockman has is one of three parts to a teleporter that would allow the alien warlord Krang to dispatch his ultimate war machine to Earth, he arranges for Stockman to assemble the other pieces. Once the portal device is complete however, Shredder dismisses Stockman's efforts and has him taken away to the Foot Clan's facility in Tokyo. April's news broadcasts mention that Stockman is currently "missing".

In the 2018 series Rise of the Teenage Mutant Ninja Turtles, he is depicted as a young boy named Baxter Stockboy who works at his family's grocery store. He attempts to gain popularity online through the use of his inventions.

Baxter Stockman appears in Batman vs. Teenage Mutant Ninja Turtles, voiced by Keith Ferguson. Baxter is shown to be a mutant housefly. While he works for the Foot, he often expresses uncertainty about whether he is an employee or a hostage, considering that he has never actually been paid for his efforts. When he is confronted by Robin during the final showdown, Baxter swiftly surrenders as he affirms his uncertainty about his status, prompting Robin to remark that Baxter is a great disappointment. He would later be evacuated when the hideout began to explode.

Stockman appears in the 2023 animated film Teenage Mutant Ninja Turtles: Mutant Mayhem, voiced by Giancarlo Esposito.[8] He is a former TCRI scientist who created the mutagen and housed a select few animals, including a housefly. Baxter is killed during a raid, but his mutations escape thanks to the fly, who acts as a separate character named Superfly (voiced by Ice Cube), who plans to construct a superweapon so that he can build a mutant army and enslave humanity for treating him and his family as outcast. He would later mutate into "SuperDuperFly" after being exposed to mutagen that merges him with a giant whale and other animals from the Brooklyn Zoo, where he uses his new form to destroy New York, eventually the Turtles and other mutants manage to defeat Superfly by using anti-mutagen and reduces him to a normal fly, where he is taken custody by Cynthia Utrom.

In the original TMNT arcade game, the Turtles face the human version of Stockman on the third level (The Sewer). He flies around the screen in a flying contraption throwing Mousers to attack the Turtles. When the game was released on the NES, the rematch with Rocksteady and Bebop on the parking garage level was replaced with a second battle with Baxter Stockman in his mutated fly form.

In Teenage Mutant Ninja Turtles: Fall of the Foot Clan for the Game Boy, Stockman's fly form is fought on the third level (The Highway). He swoops back and forth across the screen and shoots fireballs.

In Teenage Mutant Ninja Turtles II: Back from the Sewers for Game Boy, Stockman is the mid-boss in Stage 5.

In Teenage Mutant Ninja Turtles: The Manhattan Missions, human Stockman can be seen in his lab while you fight Usub Gerstalk.

In Teenage Mutant Ninja Turtles: Turtles in Time, Stockman once again returns in fly form on the first level (the construction site). He first appears on screen and says, "Terminate the turtles!" He attacks from the air and walks around and shoots at you with an Uzi. First he attacks with his Uzi, but after being damaged enough to lose the Uzi, he pulls out a weapon he used in the original cartoon (which bears similarity to a revolver), which fires 'solid energy' fists and feet to strike at the turtles, snickering whenever he lands a hit with it.

In Teenage Mutant Ninja Turtles: The Hyperstone Heist for Mega Drive/Genesis, Stockman appears in human form as the fourth boss. He flies around in a machine while dropping Mousers on the player (much like the first arcade game).

The fly version of Stockman appears in the background of "Scrapyard" stage in the SNES version of Teenage Mutant Ninja Turtles: Tournament Fighters.

In addition to cutscenes, he was a boss in Teenage Mutant Ninja Turtles, which was based on the 2003 animated series.

He appeared as a boss in Teenage Mutant Ninja Turtles 2: Battle Nexus for the Game Boy Advance as the penultimate boss bout.

He appeared as a boss in Teenage Mutant Ninja Turtles: Arcade Attack.

Although not a boss, Stockman is the prime antagonist for the 2014 Teenage Mutant Ninja Turtles movie video game adaptation for the Nintendo 3DS.

In the 2022 beat-'em-up Teenage Mutant Ninja Turtles: Shredder's Revenge, Baxter Stockman is a mutated fly-human-hybrid mad scientist who assembles and activates Krang to fight against the turtles. He is given the parts of the Krang body by Bebop and Rocksteady and Tempestra, then gains the final piece when the destruction of Metalhead activated its appearance. He is chased down by the Turtles, April, Splinter, and Casey Jones, who fight him and knock him unconscious, though he activates Krang before he can be defeated.

Lord Dregg[edit]

Lord Dregg is an alien warlord from Dimension X who replaced Shredder as the main antagonist in the last two seasons of the 1987 cartoon, voiced by Tony Jay. In his first appearances, he attempted to take over the world, but his plans were constantly foiled by the Turtles. Eventually, he started a smear campaign against them, which turned the citizens of New York against them and in favor of him. This all came to an end in the episode "Doomquest". He is unable to fight the titular villain, and when the Turtles do so, he flees in fear, and the populace finally discover that the Turtles were heroes and Dregg was the villain (after April showed them a tape of his true motives). His last attempt involved using a robotic suit to absorb the powers of several other aliens, and kill the Turtles. His plan failed after Donatello and Michelangelo used Krang's android body to shrink him down and banish him to Dimension X.

A new version of Dregg who's named Vrinigath appeared in the fourth season of the 2012 cartoon, voiced by Peter Stormare. He appears as an insectoid crime lord originating from the Planet Sectoid 1. When the Turtles incur his wrath while they were at a space port on a planet not being in the Federation, Dregg becomes one of their most dangerous enemies. He soon hires the bounty hunter Armaggon to hunt down the Turtles, later joining him in the Cosmic Ocean of Veruna in an effort to destroy the Turtles and claim a piece of the Black Hole Generator entrusted to the Daagon. Having been thwarted in this attempt, Dregg has Armaggon capture the Salamandrian G'Throkka/Sal Commander, and blackmails him and his comrade Mona Lisa/Y'gythgba into helping him capture the Turtles in exchange for sparing their world. However, after betraying them, Dregg is defeated by the Turtles and Salamandrians working together and apparently revealed to be a cyborg insect lifeform. Dregg then tracks the Turtles to Magdomar, home of the last Black Hole Generator fragment, in order to exact revenge for their destruction of his Scorpinoid. After failing to defeat them alone, Dregg contacted the Triceratons, offering to help them locate the generator fragment in exchange for a hefty bounty and the Turtles for his own vengeance. He then struck again, only to be apparently knocked into a sea of lava; however, he then swoops in during the confrontation between the Triceratons, Turtles, and Tokka and succeeds in stealing the fragment. Pursued by a flight-capable Tokka, he offers the Triceratons the fragment in exchange for saving him from her and an even larger bounty than earlier agreed upon. The Triceratons allow him on board their flagship but then jettison him into space. Dregg survived and teamed up with Newtrilizer in a plot to unleash the Vreen on New York City and take over Salamandria. Both of them are defeated by the Turtles, Sal Commander, and Mona Lisa.

Purple Dragons[edit]

Symbol of the Purple Dragons gang.

The Purple Dragons are a street gang that is documented to have connections with the Foot Clan in few incarnations and have clashed with the Ninja Turtles in several series.

They first appeared in the Mirage comics as the toughest gang from the Lower East Side in New York City. They often are led by Hun and have a connection to the Foot Clan, though not always. The leader of the "Black Dragons", apparently cut a deal with Officer Miller, which resulted in Hun being locked up and allowed him to gain control of the Purple Dragons. He then helped the Purple Dragons' one-time-rival Shredder wipe out the group, turning them into the Black Dragons: a gang subservient to the Foot Clan. In their first fight against the Teenage Mutant Ninja Turtles, the Purple Dragons found that their guns and knives are useless against their martial arts. The turtles managed to kill most of the members before the police arrive.[9] The Purple Dragons appear again 25 years later in 2009. Decades ago, the gang's leader Hunter Mason (the true identity of Hun) delivered a brutal beating to a teen-aged Casey Jones, one of the Purple Dragons' bitterest enemies, prior to being thrown in jail. After being released from jail, Hun wiped out the Black Dragons, declaring his intentions to rebuild his criminal empire.[10]

In the 1987 series, Bebop and Rocksteady are part of a street gang that works for Shredder. This gang is possibly based on the Purple Dragons.

In the IDW comics, the Purple Dragons are led by Angel Bridge. Unlike the other incarnations, the Purple Dragons are a "community watch"[11] where they do not like mutants or ninjas from the Foot Clan causing trouble on their turf. Angel's father Brooklyn S. Bridge and Arnold Jones (who is the identity of Hun in this continuity) had formerly used the Purple Dragons where their activities made the streets of Brooklyn unsafe. The leadership of the Purple Dragons was wrested from Angel by force by a resurrected Hun. As a result, the Purple Dragons reverted to their former existence as a violent street gang.

In the 2003 Teenage Mutant Ninja Turtles TV series, the Purple Dragons are led by Hun and have connections with the Foot Clan. Following the Shredder's exile from Earth by the Utroms and the discovery that Shredder was an Utrom named Ch'rell, Hun began to strengthen the Purple Dragons, developing them from just a street gang to a country-wide organized crime syndicate. They began to steal illegal goods (particularly high tech Triceratons and Federation weaponry from the government), but accidentally brought a mutant called Finn. Hun also broke his previous connection with the Foot Clan to spread their influence in the city. The Purple Dragons were among those who helped the Teenage Mutant Ninja Turtles fight the Tengu Shredder's forces.

In the 2012 Teenage Mutant Ninja Turtles animated series, the Purple Dragons are a Chinese American gang who have connections with the Foot Clan.

In the 2018 Rise of the Teenage Mutant Ninja Turtles animated series, the Purple Dragons are a trio of snobby, tech club students at April's high school who use their skills for criminal acts. They are rivals with the Turtles, especially Donatello from how they both use technology.


Hunter "Hun" Mason is the leader of the Purple Dragons featured in the 2003 animated series.[12]

Hun (voiced by Greg Carey) was an exceptionally large, muscular Caucasian with blonde hair that he wore in a ponytail and Purple Dragon and Foot tattoos on his arms.[12] Having served as a lieutenant to the Shredder and the leader of the Purple Dragons for years, he served as a recurring foe of the Turtles and a personal nemesis for Casey Jones, having set fire to a store owned by Casey's father and killing him. Hun was subsequently included into the Mirage comic line. In the IDW comics, Hun is the former alias of Arnold Jones, who in his youth was a member of the Purple Dragons, until a girl he met brought him back to an honest life. In the 2012 animated series, Hun (voiced by Eric Bauza) is the new Chinese leader of the often-defeated Purple Dragons bearing a resemblance to Bruce Lee and possessing considerable martial arts skill.[12]

Rat King[edit]

The Rat King is a more enigmatic enemy of the Ninja Turtles, with an apparent telepathic influence over rats. He is one of the only villains from the Mirage comics to reappear in the 1987 series, and he later appears in the 2003 and 2012 series.

Agent Bishop[edit]

Agent John Bishop – was first introduced as simply John is a character in Mirage Comics who first appears in Tales of TMNT Vol 2 #61 as a cameo connected to Razorback.

A superhuman version of the leader appeared in the 2003 series with a wildly different story, that of the Earth Protection Force, a group dedicated to protecting Earth from extraterrestrial attack, in the 2003 animated series, voiced by David Zen Mansley.

Originally a soldier in the Civil War, he was abducted by aliens, which embittered him towards extraterrestrials and led him to start the EPF. Through unknown means-possibly the use of clones of himself created using alien technology-Bishop survived into modern times, and first came into conflict with the turtles when the D'Hoonib Federation and the Triceraton Republic brought their war to Earth. Having forged an alliance with the Federation, Bishop helped them secure the Fugitoid Professor Honeycutt in exchange for having the Turtles to examine. Bishop had previously captured and experimented upon the Turtles' friend Leatherhead, who had previously been thought deceased, and in examining him and the Turtles found their genetic mutations to hold great promise for his never-ending war with aliens. The Turtles and Leatherhead managed to escape his clutches and fought him, but Bishop's abilities proved impressive enough to enable his escape as well. Bishop would clash with the Turtles several times, notably kidnapping Shredder's adopted daughter Karai and Master Splinter, whose mutated rodent DNA proved to be the missing piece Bishop needed to finish his Slayer Project. The Slayers, genetically enhanced clones of Bishop himself, were intended to infiltrate the human populace and weed out aliens in disguise, with little regard for any innocents who might be innocently claimed. However, the Turtles managed to destroy the Slayer project, with the only remaining specimen going renegade and reemerging as the Rat King, with Bishop being impaled by a hook used by Splinter. The Turtles would engage a returning Bishop on a number of future occasions, notably as a result of a faked alien invasion leading to him saving the President and the resulting genetic mutations that swept across New York. Eventually, Bishop would recruit Baxter Stockman to aid him and became a begrudging ally to the Turtles against the new Tengu Shredder.

A future version known as President Bishop appears in TMNT: Fast Forward. As head of the Pan-Galactic Alliance, he maintains as a friendly pro-alien liaison to the Turtles in the future after flashbacks reveal an alien prisoner saved his life 50 years in the past.

An alternate version of Bishop, an Utrom, was introduced in the 2012 television series; this one appears as an ally rather than an enemy of the Turtles and battled the Kraang. He was voiced by Nolan North.[13]

An IDW version of John Bishop exists, as the son of Wayne Bishop,[14] founder of the EPF acting very similar to the 2003 version in addition to having a robotic body.[15]

Go Komodo[edit]

Go Komodo appears in volume 3 of the original comics, published by Image Comics. He's a powerful Japanese businessman with properties in New York who surrounds himself with the trappings of a feudal Japanese daimyo. He secretly has a curse that causes him to transform into a large Komodo dragon, and seeks the Turtles and Splinter to learn the secrets of the mutagen in their blood to gain control of the condition. To that end he hires cyborgs to assault the TMNT, setting into motion the events of the series.

King Komodo[edit]

King Komodo is a mutant Komodo dragon who was part of Go Komodo's menagerie before being accidentally mutated. He winds up biting off Leonardo's hand (which later grew back). He winds up turning on Go Komodo, killing him and taking his identity when he realizes he can transform into an identical appearance. He leaves to take over Go Komodo's Japanese operations on friendly terms with the turtles.

Groundchuck and Dirtbag[edit]

Groundchuck and Dirtbag are a mutant cattle and a mutant mole.

Groundchuck and Dirtbag first appeared in "Planet of the Turtleloids" Pt. 1 voiced by Robert Ridgely and Pat Fraley. Shredder and Krang originally planned to mutate a lion and a gorilla at a zoo to be their latest henchmen Due to the Turtleloid Kerma leading the two animals away while Shredder and Krang were getting the Mutagen dispenser prepared, a cattle and a mole were accidentally released by Bebop and Rocksteady and were mutated instead. Groundchuck was given high-tech armor and a crossbow while Dirtbag received road worker clothes and a high tech shovel as a weapon. They would later be transported to Shell-Ri-La by Kerma where they acted on their own and briefly sided with the two-headed dragon Herman the Horrible (who was actually a robot piloted by the Turtleloids Bork and Dwork). When the villains were defeated, Groundchuck, Dirtbag, and the rogue Turtleloids were locked up. In "Escape from the Planet of the Turtleloids, Groundchuck and Dirtbag escape from prison where they allied with the cyborg space pirate Captain Dredd. All three were defeated by the Turtles and Kerma.

In the IDW Publishing series, two characters loosely based on Groundchuck and Dirtbag named Chuck and D.B appear. While Chuck was a mutant cattle with a missing eye, a metal right horn, a bandaged right leg with a knee pad on it, and grafts, metal plating, and screws on him, D.B. was a mutant naked mole rat with bolts on his back and a skin graft on his right leg and right foot. They are among the humans that were mutated by Old Hob's bomb. Chuck and Dirty went to go work with Jasper Barlow where they became his assistants.


Antrax is an ant villain.

In the 1987 TV series, Antrax appears in the episode "Night of the Rogues" where he is voiced by Pat Fraley. He is among the villains that Shredder assembled to attack the Turtles. His toyline bio states that Antrax is Krang's executioner from Dimension X.

In the 2012 TV series, Antrax is a mutant ant that was created by Baxter Stockman. It's abdomen can produce clones of itself.


Scumbug is an insect villain.

In the 1987 series, Scumbug appears in the episode "Night of the Rogues" where he is voiced by Barry Gordon. He is among the villains that Shredder assembled to attack the Turtles. His Toyline bio states that Scumbug was formerly an exterminator that was hired by Shredder and Krang to fumigate the Technodrome that was suffering from a cockroach infestation until he came into contact with some mutagen and one of the cockroaches.

In the 2012 series, Scumbug is voiced by Ted Biaselli. He is an unnamed stuck-up businessman who Baxter Stockman kidnapped and mutated into a stag beetle/spider mutant.

A female version of Scumbug in Teenage Mutant Ninja Turtles: Mutant Mayhem, with her vocal effects provided by a blend of Alex Hirsch and some uncredited voice actors. Despite the advertisements identifying the character as "himself", the film, as well as the filmmakers, clearly identify her as female.[16] Scumbug is depicted as a mutant cockroach and the only one who does not speak. She can only speak in "vermin" that Splinter can understand. By the end of the movie, the two of them become a couple much to the Turtles' disgust.

Savanti Romero[edit]

Savanti Romero is a former servant of Lord Simultaneous and an enemy of Renet. He appears in the Mirage and IDW Comics.

In the 2003 animated series, Romero is voiced by David Zen Mansley. He retains his Mirage backstory of being a transformed treacherous apprentice of Lord Simultaneous, and is first shown trying to capture the Time Scepter in Earth's Middle Ages. When foiled by the Turtles and Renet, Lord Simultaneous banished him further back in time to Earth's Cretaceous Period. Romero would serve as the main antagonist of the "Return of Savanti" two-parter in which he tries to avert the asteroid impact that would wipe out the dinosaurs, seeking to rule the Earth in a world where humanity never evolves. The Turtles and Renet once again defeated him, and this time Romero perished for good.

In the 2012 series, Romero is voiced by Graham McTavish and is much more comedic than his 2003 counterpart. As with his previous incarnations, he is defeated by the Turtles and Renet in Earth's Middle Ages and banished to the Cretaceous Period. However, he makes his way back to the present and begins traveling through time to build an army of monsters, bringing in the likes of Count Dracula, a mummy, a werewolf, and Frankenstein's monster. Romero enters a power struggle with Dracula who commands most of their forces, and agrees to an equal partnership with him. However, Dracula is killed during the final battle with the Turtles and Romero is returned to the Cretaceous Period, this time being killed by a dinosaur for good.

Upon the ship landing on an Eden World where Rocksteady and Bebop were on, the two of them accompanied the villains back to Earth. Once on Earth, Bellybomb grafts Krang to Shredder's body while the Turtles were busy fighting Rocksteady, Bebop, and Slash. After the Turtles freed Shredder from Krang's control, Bellybomb and Krang were sent back to Morbus while Slash escapes.

Venus de Milo[edit]

Venus de Milo was introduced as the first female Ninja Turtle in Ninja Turtles: The Next Mutation and was originally created specifically for that iteration. Unlike the four original Turtles she wasn't trained in Ninjutsu and rather utilised ancient shamanistic magic and manipulated orbs to fight. She dons an aqua colored bandanna. Within the continuity of the series when Splinter rescued the Turtles, he accidentally left Venus behind. She made her way to Chinatown and was found and raised as a daughter by a Shinobi magician who named her Mei Pieh Chi.[18]

A new version of Venus was released in the IDW Comics continuity with Issue #127 on March 30, 2022.[19] This incarnation is a Frankenstein-like creature with telepathic abilities created by the mad mutant surgeon Doctor Jasper Barlow from the remains of a female Punk Frog named Bonnie.


Jennika (nicknamed Jenny) is the second female turtle introduced in the franchise after Venus de Milo. She was created for the IDW Comics series. She wears a yellow mask and her weapon of choice are tekko kagi claws. She was initially a human foot clan member. After being defeated in an assassination attempt on Splinter, she was put under the tutelage of Leonardo and began to warm up to her new family. After being stabbed by Karai, Jennika was given an emergency blood transfusion from Leonardo. The mutagen and turtle DNA in Leo's blood bonded with Jennika and mutated her into a mutant turtle.[20] Despite her loyalty to the team, due to her near-death experience, Jennika still has unresolved anger issues towards Karai.

Baron Draxum[edit]

Baron Draxum (nicknamed Barry) is from Rise of the Teenage Mutant Ninja Turtles (voiced by John Cena in season one,[21][22] Roger Craig Smith in season two). As the self-proclaimed protector of all Yōkai, Draxum seeks to mutate humanity to avert a prophecy predicting their destruction.[23]



The Neutrinos are extra-dimensional beings from Dimension X. They first appeared in the 1987 animated series as a group of elf like aliens, a trait which is carried over to the Archie and IDW comics. The notable members were Dask, Kala, Zak, Princess Trib, King Zenter and Queen Gizzla.

A group of Neutrinos appear in the 2012 series but re-worked as microscopic antagonists and with a different more bulky, intimidating design.

The Neutrinos appear as cameo characters in the 2022 beat-'em-up Teenage Mutant Ninja Turtles: Shredder's Revenge.


The Triceratons are a race of alien Triceratops governing a wide empire/Triceraton Republic. They are enemies of the Turtles and the Fugitoid. They're featured in the 1987, 2003 and 2012 animated shows.


Dimension X[edit]

Dimension X is a parallel dimension that has various adaptions in each media appearance:

In the 1987 cartoon, Dimension X is the home of several characters, most notably Krang, one of the series' main antagonists. Krang typically uses the Dimensional Portal located inside the Technodrome for transportation between Dimension X and Earth, although other portals and means of travel are occasionally seen. It is depicted as a hostile, war torn galaxy with foreboding landscapes and many fierce monsters. Although it is also home to many peaceful species such as the Neutrinos.

In the Archie Comics, Dimension X is a spiral galaxy in which numerous inhabited (or habitable) worlds are located. It was originally governed by theocrats, banishing all warlords.[24] Later, there's a conflict between the Imperial Aerwyl Fleet and the Nova Squadron.[25]

In the IDW Comics, Dimension X is depicted as a warzone controlled by Krang where the Utroms, the Triceratons, and the Neutrinos are fighting for their planets.[26]

In the 2012 Teenage Mutant Ninja Turtles TV series, Dimension X is the home dimension of the Kraang and the Utrom. So far, it is known that the pink air of the Kraang's part of Dimension X is nitrogen mixed with sulfur and that it is very foggy. The water of Dimension X has hydrocarbon that can melt anything in the Dimension of Earth. For some reason, the water had no effect on April O'Neil when some of it was accidentally splashed on her (it was later revealed to be because she's a human/Kraang hybrid which also made her immune to the Mutagen's effects). Time moves faster in Dimension X, with Leatherhead spending decades there within the period of a year passing on Earth. Dimension X is also home to the Triceratons and has served as the battleground for a war between them and the Kraang.

Dimension X was featured, unnamed, in the 2016 sequel film to Teenage Mutant Ninja Turtles. The filmmakers first expressed interest in featuring the Dimension X in the sequel in 2014.[27] In the film, Shredder is transported from a police convoy to the Technodrome in Dimension X in which he agrees to help Krang conquer Earth. The Technodrome is later transported to Earth in the film's climax, though the Turtles manage to return it to Dimension X. The film never shows the Dimension X's exterior as the only scene taking place there is inside the Technodrome, while it appears off-screen in the climax.

Crossover characters[edit]

Several characters from other comic book series have crossed-over into the TMNT universes. Notable appearances are listed below:


Cerebus the Aardvark[edit]

Flaming Carrot[edit]


Knight Watchman[edit]

Power Rangers[edit]

Sarah Hill/Horridus[edit]

Savage Dragon[edit]

Miyamoto Usagi[edit]

Miyamoto Usagi is a samurai rabbit and master swordsman from an alternative universe's 16th century Edo period in Japan, where animals are the dominant species, not humans. He appeared in two episodes of the 1987 series. Usagi Yojimbo is a comic book series created by Stan Sakai starring the rōnin hero rabbit, Miyamoto Usagi, which had several crossovers with the TMNT comics; however, the TV show writers did not understand the distinction and misnamed the character after the comic book.

The character returned for the 2003 animated series with his actual name Miyamoto Usagi, and became a friend and close ally of the turtles, especially developing a strong friendship with Leonardo, since both are swordsmen, and during Season 4 he is summoned by Splinter to talk with Leonardo about Leo's new harsher attitude (as a result of the Turtles and Splinter nearly sacrificing themselves against Utrom Shredder at the end of the third season). Leonardo also ended up in Usagi's dimension when Ultimate Draco scattered the five mutants to different parts of the multiverse. In the series finale, he is invited to April and Casey's wedding.


Wild West C.O.W.-Boys of Moo Mesa[edit]

The Wild West C.O.W.-Boys of Moo Mesa are a trio of anthropomorphic cattle that work as cowboys, defending their home of Cowtown from various criminals. The group consists of Marshal Moo Montana, Dakota Dude, and Cowlorado Kid.

In issue #21 of Tales of the TMNT, the Teenage Mutant Ninja Turtles aided the C.O.W.-Boys into stopping the Masked Bull (the criminal alias of Sheriff Terrorbull) from stealing a magic crystal shard.
