The Mighty Mutanimals (2021 Series)

The Mighty Mutanimals is a CGI Nickelodeon cartoon series which starts as a spin-off series from Nickelodeon's Teenage Mutant Ninja Turtles. It is loosely based on an old spin-off comic with the same name.

Synopsis

Set in an alternate timeline five months after the series finale of TMNT 2012, the Turtles learn about new enemies who are more deadly and stronger than the Foot Clan or the Kraang. And so, they decide to team up some allies and some former enemies to help them take down these forces before they destroy them all.

Characters

The Mighty Mutanimals

• Slash (Corey Feldman) - An immensely strong and compassionate mace-wielding mutant tortoise and the leader of the Mighty Mutanimals. Originally the beloved pet of the Ninja Turtle Raphael, Spike (as he was known as before his mutation) came to believe his master's brothers were horrible to him due to Raph venting his frustrations to his non-mutated friend for years and willingly consumed the contents of a mutagen canister that transformed him into a hulking teal-skinned terrapin with superior physical attributes and ninjitsu skills, but also warped his mind into believeing that the other Ninja Turtles mistreated Raphael and sought to destroy them, only to be defeated when Raph discovered his former pet's intentions and defeated him with a well-placed nerve attack. At some point after his defeat, Slash encountered the vindictive Newtralizer after the latter saved him from being imprisoned by the Kraang, striking up a friendship with the Salamandrian and aiding him as a partner in his mission to wipe out the nefarious aliens. Though initially pleased with the progress of their mission, Slash began to have second thoughts about his partnership with Newtralizer when the latter began displaying troubling signs of indifference towards the potential casualties that could be caused by his increasingly drastic attacks on the Kraang, which eventually led to Slash ending their partnership and striking out on his own. He and Newtralizer have a relationship similar to that of Leonardo and Raphael, meaning that they frequently bicker about what the team should do yet they ultimately respect each other at the end of the day. As leader of the Mutanimals, Slash is loyal and protective of his comrades; acting like a big brother figure to the younger members of the group. Slash always looks for ways to improve himself as a ninja, often training with Karai, Alopex, Splinter, and the Turtles to further his ninja skills.
• Alopex (Minae Noji) - The younger sister of Tiger Claw. Originally a human girl; Alopex and her brother were abducted by the kraang as children, and mutated. Eventually the two escaped, and found refuge in a circus before becoming assassins in the criminal underworld. Originally she held a grudge against Tiger Claw for everything that happened to her, and sliced off his tail. After her attempts to curse her brother with the Cursed Blades of Vengeance failed, Alopex wandered New York alone for sometime until she ran into the Mighty Mutanimals. After some soul searching she would eventually join them. Alopex can come off as cold and distant at times, but does care for her comrades, who've become a second family to her. She suffers from immense Post Traumatic Stress Disorder and trauma during her time as an assassin (Despite her targets being other criminals). Eventually Alopex would come to terms with her past and move on. She uses her super speed and twin Kamas in battle.
• Leatherhead (Peter Lurie) - A fierce-looking but benign mutant alligator and the enforcer of the Mighty Mutanimals. As a hatchling, the alligator who would become Leatherhead was the pet of a kind human teenager until the boy's revolted parents flushed the hatchling into the sewers where he was found by the Kraang and brought to their dimension, where he was used as a test subject for the Kraang's horrific mutagen experiments, an experience that that left him so psychologically damaged that the even hearing the word "Kraang" would drive him into a murderous frenzy. He eventually escaped from the Kraang's clutches with the power cell that powered their dimensional portal and made his way into the sewers, where he later encountered the Ninja Turtles when they saved him from a Kraang ambush and brought his unconscious body to their home. Thanks to the efforts of Michelangelo, Leatherhead became a valuable ally in their battle against the Kraang, entrusting them with the power cell he stole so that they could use it to power their recently-built Shellraiser. He hopes for a peaceful future between man and mutantkind.
• Newtralizer (Danny Trejo) - A hardcore and pugnacious Salamandrian bounty hunter and the weapons specialist and second-in-command of the Mighty Mutanimals. A longtime prisoner of the Kraang who despised the alien race almost as vehemently as Leatherhead, Newtralizer armed himself to the teeth with a wide arsenal of firearms, blades, and explosives to embark on a one-newt war against his former captors. Though devoted to his cause, Newtralizer was otherwise fully apathetic of the lives that were jeopardized by his actions and only cared about achieving his goals, a characteristic that caused for a bad first impression with the Ninja Turtles during their attempt to rescue Kirby O'Neil from the Kraang (despite the fact that Donatello had inadvertently freed the Salamandrian and allowed him to regain most of his arsenal). Some time after this venture, a raid on a Kraang facility earned Newtralizer a new partner in the form of Slash, the mutated former pet tortoise of the Ninja Turtle Raphael, though this partnership was short-lived after Newtralizer's obsession with ending the Kraang menace and indifference towards the potential casualties brought upon by his actions caused a repulsed Slash to betray him. After recovering from this encounter and realizing that his obsession with vengeance cost him the trust of his only friend, he now sees how heartless he was and promises to put humans first, if it means defending the city from peril. He is often partnered up with Slash. It's later revealed that he is actually a clone of a Salamandrian criminal known as K'Vathrak.
• Martin Milton/Sir Malachi (Jacob Wysocki) - A flamboyant and immature mutant sparrow and the mystic/diversion artist of the Mighty Mutanimals. Martin Milton was once an average 11-year old geek who hid his feelings of low self-esteem behind his obsession of the roleplaying game Mazes and Mutants, playing it every hour of every day. While feeding the birds on his roof to get some fresh air, a canister of mutagen fell on him and mutated him into a mutant sparrow with powerful illusion casting abilities, leading Martin to renaming himself Sir Malachi the sparrow wizard and heading into the sewers to continue his 24/7 roleplaying regiment. Eventually growing tired of playing alone, Malachi began to long for someone to play his beloved game with and eventually discovered the existence of the Ninja Turtles in the sewers before planting his board game near their home so that they would discover it and fall in love with it the same way he did. He has somehow gained legitimate magical powers ever since his encounter with the Turtles.
• Dr. Tyler Rockwell/Monkey Brains (Tom Kenny) - An extremely agile and intelligent mutant chimpanzee and the acrobat, strategist and psychic of the Mighty Mutanimals. Formerly a skilled and principled neurologist working in New York, Dr. Tyler Rockwell was betrayed by his selfish and immoral collaborator Victor Falco when the latter used a sample of mutagen and some monkey DNA they were experimenting on (both of which were given by the Kraang presumably to create a new mutant minion) to mutate him into a humanoid primate with enhanced strength, agility, dexterity, and emotion-sensing abilities, which Falco sought to extract to give himself mind-reading powers of his own. After managing to escape his imprisonment, Rockwell was later re-captured by the Ninja Turtles and brought back to Falco after the latter lied to them that Rockwell was merely a lab ape affected by the mutagen, which allowed Falco to inject his betrayed colleague's mutated blood into his body to grant himself telepathy which gave him an advantage over the Ninja Turtles. Fortunately, Donatello was able to shield his mind from Falco's telepathy and defeat him before freeing the grateful Rockwell into the city, though Falco managed to escape down an air vent the Turtles threw him into. Some time later, Rockwell was captured on the Kraang and experimented on, which caused him to regain his high intellect and power of speech (his natural voice sounding noticeably similar to the character Gibson from Super Robot Monkey Team Hyper Force Go!) while also enhancing his emotion reading ability to full-on telepathy, telekinesis, and clairvoyance. Having these newfound powers, he is able up a telepathic link with his teammates which makes the use of electronic communication unnecessary (except when the Turtles have to communicate with the Mutanimals through their T-Phones).
• Pigeon Pete (A.J. Buckley) - A jumpy and neurotic but sweet-natured mutant pigeon and the aerial specialist of the Mighty Mutanimals. Originally one of the millions of pigeons inhabiting New York City, Pete was captured by the Kraang and mutated into an anthropomorphic state with the power of speech, while still retaining his ability to fly. He is not as brave as his teammates, but is still a kindhearted mutant who is always willing to help others in need. He is also obsessed with bread, which acts as a source of humor for Slash and Mondo Gecko because they enjoy teasing him with it. After joining the Mutanimals, he becomes equipped with a weaponized harness with laser blasters positioned on his shoulder blades and a concussive blast projector positioned on his chest.
• Y'Gythgba "Mona Lisa" (Zelda Williams) - One of the latest members of the Mutanimals. She is a female Salamandrian warrior, and Raph's girlfriend. Originally a soldier in the Salamandrian army, Mona Lisa and her commander G'Throkka "Sal Commander" met the turtles on their quest for the blackhole generator fragments. After clearing up misunderstandings she became an ally to the Turtles and Mutanimals. Eventually she would stay on Earth as a representative (With both Bishop and G'Throkka's permission" and would aid the Mutanimals on their mission. Though her main reason for staying on earth is to be with Raph, Mona treats her new surroundings as a challenge - knowing that earth is different from other plants. Though Mona Lisa is a proud fighter, she can be humble and willing to admit when she's wrong. Being interested in Physics, Mona Lisa often looks for ways to create weapons using said science. Mona Lisa was once believed to be a pure salamandrian, only to learn that her mother was originally a Humanoid Terran from D'Hoonib who was mutated by a Space Pirate named Phineas Filch, making Mona Lisa half mutant. She wields a plasma sword and a blaster. She has a rivalry with Newtralizer due to his history with her commander.
• Jason "Mondo" Cabezo/Mondo Gecko (Robbie Rist) - A laid-back and fearless young mutant gecko and the infiltration expert of the Mighty Mutanimals, as well as an expert skateboarder and Candy Fine's boyfriend. Carefree and thrill-seeking, Jason Cabezo was once an average teenage skateboarder who spent most of his days skating down the streets of Manhattan with his pet gecko Lars on his shoulder. One night, while skating on his homemade half-pipe outside his home, Jason was struck from above by a falling mutagen canister (one of the many that were lost during the events of The Mutation Situation) and exposed to its contents when it shattered on him. Because he had recently touched his pet gecko Lars, Jason was mutated into a short, anthropomorphic mutant gecko with the ability to climb on walls and ceilings and was summarily kicked out of his home after his parents discovered his mutation. He owns a rocket-powered skateboard which he uses to travel around the city and is armed with a pair of energy blades that can be connected to make a dual-ended sword.

Allies

• Jack Kurtzman (Bob Odenkirk) - The benefactor of the Mutanimals. He often is the one to assign them on their missions. Originally a journalist, he stumbled on the Kraang, and aided the turtles with beating them. He gathered the Mutanimals together to combat the Kraang. Kurtzman cares deeply about the Mutanimals, but won't put up with their antics if it affects the team. He often acts like recon when the group is on their missions. One of Kurtzman's goals is to help mutants like the Mutanimals and the turtles be able to live in human society without fear of being shunned. He is working with the Utroms, and G'Throkka to ensure it.
• Kara Lewis (Wendie Malick) - A no-nonsense police officer. When she first met the Mutanimals, Kara was initially distrustful, and not because they weren't human. However Kara grew to trust the heroes as they worked to stop the Kraang. Kara acts like a mother figure to Jason and Malachi. Kara tends tries to stay calm in a situation, but won't hesitate to be reckless if needed.
• Mousepad (Jenny Slate) - A mutant mouse and a reserve member of the Mighty Mutanimals. She is an extremely intelligent (and slightly nerdy) young mutant (about Malachi's age) capable of creating incredible inventions and is armed with a cornucopia of self-made gadgets (which include magnetic boots, flight-enabling ankle jets, wrist blasters that fire electron beams and powerful adhesive paste, and a robot probe she can control thanks to circuitry in her helmet that can cling to her back or walk on four legs). After being mutated by the Rat King to act as a "mentee" in his quest for world domination, Mousepad was ordered to build a device that would allow her master to amplify the reach of his telepathic powers to every inch of the city. This didn't stand with the Mutanimals and they tried to stop the Rat King, only to be overwhelmed by the Squirrelanoids and be readied to die at Mousepad's hands. Out of desperation, Sir Malachi smooth talked Mousepad by complimenting her intelligence and inventions, causing the flattered mouse to develop a huge crush on him. This newfound affection, along with her uncertainty of helping her master, convinces her to rebel against the Rat King and help the Mutanimals defeat him, then to join the Mutanimals and their allies in their quest for battling the Kraang. She resides in an abandoned lab and acts as the Mutanimals' go-to-girl for technological expertise, having built Hot Spot's water cannon and the Punk Frog's weapons.
• Commander G'Throkka "Sal Commander" (Keith David) - Mona Lisa's commander and mentor. He and K'Vathra used to be comrades in arms until K'Vathrak betrayed his unit and left G'Throkka for dead. Though more level headed them most Salamandrians, G'Throkka won't hesitate to fight if needed. Though he was hesitant to trust the turtles, and the Mutanimals (especially Newtralizer), he would later see that Newtralizer and K'Vathrak were two different people. When Mona joined the Mutanimals, G'Throkka was assigned to oversee Earth and aid the Utroms, Kurtzman, and Mona Lisa in their mission to create the Pangalactic alliance.

It's later revealed that his family was also affected by the Kraang; unlike April's however, Casey's father had no idea of his wife's, Gabriella, connection. It's furthered shown that Casey and his family, via his mother's side, come from a long history of humans who weren't able to be mutated by mutagen.
• Hamato Yoshi/Splinter (Hoon Lee) - The turtles' mutant rat sensei and Karai's father. Hamato Yoshi was the son and heir of the leader of the Hamato Clan, whose rivalry with the Foot Clan came to an end when he was a child. It was this victory that brought into his family Oroku Saki (Shredder), the child of the Foot Clan's leader, who Yoshi welcomed into his clan as a brother, maintaining an intense but healthy competition with him in their ninja training. As they grew older, their brotherhood was tested (and failed) when both they fell in love with the same woman, Tang Shen, who ultimately chose Yoshi over Saki. As a result, ultimately because of Saki's own jealousy and hatred, their brotherhood ended bitterly, and Yoshi and Shen married and had a daughter named Miwa. Unfortunately, when Shredder learned of his Foot Clan heritage, he attacked Yoshi in the Hamato Clan monastery, seeking to avenge his clan's extinction. During their struggle, a blow meant for Yoshi took the life of Shen, and Shredder, blaming Yoshi for his own error, burned down the monastery and left Yoshi for dead. In disgrace at the loss of both his wife and child, Yoshi left Japan to start a new life in America as "Splinter". After moving to New York City, he had just purchased the Turtles, who were four baby non-mutated red-eared sliders back then, from a pet shop when he was bumped by a strange man in the street. Suspicious of the man, Yoshi followed him and witnessed a conversation between two human-disguised Kraangdroids, only to be spotted by the Kraang who attacked him to keep him quiet. During the fight, the canister the Kraang were carrying broke open and splashed the Turtles and Splinter with mutagen. As the result of stepping on a brown rat while entering the alley, Splinter mutated into a humanoid mutant brown rat. Realizing he could no longer live a normal life on the surface, he retreated to the sewers where he raised his pets as his sons for fifteen years and taught them the ancient Japanese fighting art of ninjutsu. He is very protective of his sons, daughter, students, comrades, and can sometimes be overprotective. Unlike in the previous series, Splinter survives his encounter with Shredder.

On one of her missions, she and Draxum destroyed the Kraang's latest work, and stole their latest creations "Lou and Hana." Down the line Amaya and Draxum would discover the Kraang's attempts to mutate five turtles. The incident would later mutate her into a Tiger. That would be the last night they would see the Kraang as she and Draxum believed their "Leader" Sub-prime was destroyed with thousands of Kraang Soldiers. For 15 years, Amaya hid with Draxum in the hidden city raising the five turtles and the two human clones as their children, and eventually fall in love. Amaya was surprised to see Yoshi and Karai alive, and horrified by everything they've been through. Amaya is a stern parent towards her children, but is loving and doting.

Robyn's competitive nature caused for a less-than favorable first impression upon meeting the Mutanimals, especially for Newtralizer since he considered Robyn a loose cannon and a hindrance to their mission. While attempting to stop Road Hog, El Hippo, and Megamoth from stealing a vat of mutagen (which had the DNA of a komodo dragon mixed with it thanks to Megamoth), Robyn's impulsivity became her undoing when her attempt to charge at Road Hog (who had humorously bent down to pick up a lost dime) caused her to trip over the mutant pig and fall into the vat of mutagen, resulting in her transforming into a mutant komodo dragon with enhanced agility and strength, sharp claws and teeth, powerful jaw strength, and acidic saliva, and was later dubbed "Komora" by Mondo Gecko. Though initially ashamed and bitter at her mutation, Robyn begins to enjoy her newfound mutant powers and eventually develops romantic feelings for Newtralizer, which later turn out to be mutual.

  • Traximus (Khary Payton) - A young (20 years old by human standards), strong-willed and devoted member of the Triceraton army, Traximus was well-known for his determination to stop the Kraang menace and creating his signature weapon: the gun staff. Though he originally upheld the ways of his people like many others in the Triceraton Army, Traximus eventually became disillusioned with his race's warmongering lifestile and hoped to abandon their conquest against the Kraang in favor of finding a new planet to re-populate on. Being a Triceraton, Traximus possesses greatly enhanced physical attributes and is also a skilled fighter with his gunstaff, a self-made weapon of his that functions as both a melee weapon and a blaster, being able to shoot lasers, concussive blasts, plasma, electricity, and bright light.

Stoic, apathetic, gloomy and brooding, Alathea’s indifferent nature conceals a compassionate heart and usually gives away to reveal a more playful and affectionate relationship with her boyfriend Traximus, who frequently turns to her for solace whenever he feels their conflict with the Kraang is unsolvable. In one such instance, Alathea encouraged Traximus to look outside Dimension Z on Earth for a way to gain leverage against the Kraang, which led to Traximus discovering the Ninja Turtles and the Mutanimals. She was later assigned the duty of brainwashing the mutants into being the Triceratons’ slaves, but was thwarted by Michelangelo and Traximus, who told her how corrupt their race had become in their war with the Kraang and implored her to come back to Earth with them. She declined, instead choosing to remain in Dimension Z to act as a mole for Traximus and the Mutanimals and giving them inside intel on the Triceratons’ operations.

Disappointed at seeing his comrade's creation destroyed, Road Hog managed to rebuild Opticlops but not without having to make some adjustments to his damaged AI chip that changed the once monotone Opticlops into a more lively, energetic android that eventually annoyed the rest of Mutant Master's army into expelling him from their ranks.

  • Cap'n Mossback/Crabcake (Ron Perlman) - A surly yet faithful mutant crab and Mutant Master's second-in-command and confidant. Originally a shrimper from New Orleans who came to New York to open his own restaurant, Cap'n Mossback's Cajun Cuisine was short-lived when a battle between the Mighty Mutanimals and the Kraang resulted in the building being reduced to rubble and Mossback swearing vengeance against the group of heroic mutants. During an attempt at ending the Mutanimals, Mossback's harpoon gun ended up breaking a tank of mutagen laced with crab DNA which poured onto him and mutated him into a large mutant crustacean with great strength, powerful crushing claws, ans a highly durable shell. Embittered by his mutation, Mossback soon met Mutant Master, who convinced the mutant crab to pledge his allegiance to him and aid him on his conquest for world domination.
  • Rufus Barnaby/Road Hog (Harland Williams) - A bumbling yet clever leather-wearing mutant pig and expert motorcyclist and the "Mighty Mutanimals" incarnation of Bebop. Originally a member of a biker gang called the Street Boars who came to New York to reclaim their mascot pig from a rival gang, Rufus Barnaby was mutated into an anthropomorphic swine after being struck from above by a falling mutagen canister while victoriously raising his gang's mascot into the air. While a subordinate of Mutant Master, he is a rather lighthearted, humorous and optimistic mutant who genuinely believes Mutant Master is helping the world by mutating it, though he is not above helping the Mutanimals if the situation demands it. In fact, his amicable nature and sense of humor make him the most approachable member of Mutant Master's army to the point where battles between him and any of the Mighty Mutanimals are surprisingly casual. Additionally, Road Hog is shown to be friends with numerous other mutants in the city despite the fact that some of them do not share his master's belief's of mutant supremacy, with Hardrock and Fang Glider being his closest friends outside Mutant Master's army. He is also a very skilled mechanic, having built his weaponized motorcycle and modifying other vehicles with weapons and whatnot. His main weapons are a crowbar and a long chain with a gutting hook attached to the end of it.

Originally a tough and ruthless yet past-his-prime Mexican wrestler named Santiago Delgado AKA El Malevolo, he was left disgraced after a greatly damaging losing streak drove him to start taking bribes, which got him banned from entering the ring again after getting caught. Seeing Delgado in his miserable state, Road Hog appealed to the disgraced Luchador's desire to become strong again by suggesting he got himself mutated, the only price being he must swear his allegiance to Mutant Master. All too eager to get revenge on those who he felt had wronged him, Santiago doused himself with a canister of mutagen that some hippo DNA mixed into it, transforming him into a massively rotund yet immensely strong and fast mutant hippopotamus, and took on the name El Hippo after extracting revenge on his enemies.

Initially growing up penniless on the streets of Jamaica, Jemarcus DeCosta rose from the gutter over time and became the world’s most notorious jewel thief, always staying one step ahead of the law by traveling the globe under the guise of a successful kickboxing instructor. While in New York after successfully stealing a rare diamond, Jemarcus came across a lone mutagen canister (one of the many that were lost during The Mutation Situation) inside a dumpster and took it back to his safe house, thinking it would make a good lava lamp. As he got comfortable with his pet wolf Caspian, Decosta was taken by surprise when the NYPD burst into his hideout to arrest him, which caused him to stumble and fall in alarm and spill the mutagen on himself and Caspian as he went to help his master. Because he had his bare arm slung over his wolf’s back when the mutagen came down on him, Jemarcus was transformed into a large, burly mutant wolf with superhumanly enhanced physical attributes, heightened senses, sharp claws and teeth, and the ability to disorient opponents by howling and fled into the city after furiously beating up the officers who startled him. Having sensed Jemarcus’ mutation into a wolf, Mutant Master sent Road Hog out to retrieve the mutant lupine and recruit him into the former’s army, which Dreadmon (the name given to him by Road Hog) agreed to do.
  • Trevor Carlyle/Terrorcuda (Billy West) - A tenacious and highly aggressive mutant barracuda and the "Mighty Mutanimals" incarnation of Xever/Fishface. Having been on the wrong side of the law since his teen years, professional burglar Trevor Carlyle committed crimes not only for self-gain, but also for the addictive feeling of adrenaline pumping through his body whenever he evaded the police, his philosophy being: “think fast, act quicker, live in the moment”. During one such heist, Trevor attempted to evade the police by making a shortcut through the city aquarium, only to stumble and fall into the barracuda tank and be bitten by one of the barracudas before managing to escape. Unfortunately, Trevor’s luck got worse after he was struck from above by a falling mutagen canister and was mutated into a legless mutant barracuda, forcing to jump back into the barracuda tank to avoid dying from asphyxiation where he was summarily caught by the cops and given to some scientists who wished to study (and perhaps dissect) him. While en route to the scientist's laboratory, Trevor was freed from the truck that was carrying him by Road Hog, El Hippo, and Dreadmon, who then took him back to their hideout so Mutant Master could recruit him. Trevor agreed to join Mutant Master's army after he promised Trevor he could make him go fast again, which was accomplished after Adrian built Trevor a breathing harness, robotic legs with wheels for feet to allow high-speed travel by skating, and retractable blades on his arms.

For a brief time, Adrian allowed his cousin to work at his company due to Baxter's own technological expertise but was forced to terminate Baxter's contract over his inability to get along with his co-workers and violating company policies due to his feeling that his kinship with Adrian made him above the rules. Adrian is composed, respectable, eloquent, sardonic; everything that Baxter isn't. He accidentally gets mutated into a death's head hawk moth and obtains the powers of flight, enhanced strength, wall-crawling and sticky goo projection from his mouth to trap enemies in cocoons. While he holds no animosity towards the Mutanimals, he's lead on to believe that they were the ones who mutated his cousin, thus making him an enemy.

Despite his good intentions, Timothy was completely inept as a crime fighter, having little to no combat skills despite Donatello's attempt to train him in basic self-defense. After being recruited into the Foot Clan (mainly to serve as a "cannon fodder") so he could gather intelligence on the Shredder's plans for the Turtles, Pulverizer volunteered to be the test subject for a supply of stolen mutagen, hoping it would turn him into a hero like the Turtles. Despite the Turtles' multiple attempts to dissuade and prevent him from mutating himself, Timothy managed to douse himself in mutagen, which caused him to mutate into a huge mutant blob of mutagen with floating organs and a disintegrating touch, a mutation that was the result of him not coming in contact with any living thing before the mutagen touched him. He was eventually frozen by Donnie to protect April, but freed by Mutant Master and planned to used him for his own purpose. However, coming in contact with Mutant Master and retro mutagen affected Timothy's mutation, granting him the ability to change forms like Karai.

Deciding to use his new powers to protect the ocean, Finney took on the identity of Man-Ray, champion of the sea, and began his mission to prevent the ocean from facing ecological devastation. Over time however, Finney's determination with fulfilling his altruistic ideals caused him to lose touch with his humanity, and his efforts to stop those he felt were harming the ocean became increasingly drastic to the point where they were considered acts of eco-terrorism, which eventually put him at odds against the Mighty Mutanimals. While Man-Ray holds no animosity towards the team of heroic mutants, even coming to aid them at rare instances, he will not hesitate to fight them if he feels they are interfering with his mission, making the relationship between them difficult to understand. In battle, he wields a trident.

Originally a powerful crime boss in New York's criminal underworld, Boss Hugo Giovanni realized he needed to step up his game when the city's mutant population began to make itself known to the public. Reasoning to his men that they would need to adapt to the changes in New York so as to avoid going the way of the dodo, Hugo enlisted the services of a semi-unwilling Adrian Stockman to help mutate him into a more powerful form. Using a canister of mutagen with the DNA of an orangutan mixed within it, Adrian was able to mutate Giovanni into a large, rotund, yet immensely strong and agile mutant orangutan, and was dubbed "Oranguton" by Mondo Gecko during his first encounter with the MM, which mildly annoys him since it references his weight. He wields a pair of brass knuckles and Kraang blasters in combat.
  • Cliff Douglas/Buttercup (Thomas F. Wilson) - An large, aggressive, dim-witted mutant bulldog and the enforcer of the Cobalt Brotherhood, as well as Oranguton's second-in-command.

After an important gold heist that was thwarted by the Mighty Mutanimals forced the gang to retreat without so much of an ounce of the stolen gold, Cliff’s wounded dignity and desire for payback against the Mutanimals was enough for Boss Giovanni to convince him to be mutated into an even stronger form than his human one. Using some mutagen mixed with some DNA from his recently deceased pet bulldog, Cliff was mutated by Adrian Stockman into a massive mutant bulldog with immense physical strength and heightened senses of hearing and smell. Feeling as though he was missing something, Cliff had his teammate Miguel Calavera make him a spiked collar as a fashion statement, but was oblivious to the fact that Miguel had added a nametag bearing the name “Buttercup” to the collar until a re-encounter with the Mighty Mutanimals, who officically dubbed him “Buttercup”. Unlike Chris Bradford's mutated forms as Dogpound and Rahzar, Cliff is much more in touch with his animal side as Buttercup, as evidenced by his habits of eating canned dog food, chasing squirrels and cats, and urinating on fire hydrants. He also wears black gym shorts.
  • Percival Blixton/Toxin (Charlie Adler) - An impatient and high-strung mutant poison dart frog and the strategist of the Cobalt Brotherhood.

After kidnapping Adrian Stockman and gaining an understanding of the mutagen’s workings after Boss Giovanni was transformed into a mutant orangutan, Blixton chose to be mutated into a poison dart frog, which granted him the ability to poison people through physical contact, leap great heights and distances, stick to surfaces with his sticky fingers, and fight with his prehensile, 30-foot long tongue. Unfortunately, Blixton’s mutation was considered a serious hazard to the gang by Boss Giovanni, who forced Blixton to don a suit and gloves to avoid poisoning his teammates.

His main weapons are a pair of fencing swords which he wields with deadly skill.
  • Cain Westwood/Snake Eyes (Michael Rosenbaum) - A lethal yet casual mutant diamondback rattlesnake and the marksman of the Cobalt Brotherhood. An expert at sharpshooting even as a child, Texas citizen Cain Westwood became employed as the resident marksman for Boss Giovanni’s Cobalt Brotherhood after he was dishonorably discharged from the armed forces. Following a failed gold heist (which took months of careful planning) that was thwarted by the Mighty Mutanimals, an agitated Cain agreed with his Boss that they would have to “level the playing field” and become mutants themselves to better defend themselves against the Mutanimals. Deciding to mutate himself into the same creature he first fired a gun at and killed as a boy, Cain was mutated into a mutant diamondback rattlesnake with great speed, venomous fangs, crushing coils and a flexible physiology that allows him to squeeze through small spaces and passageways (e.g. air vents) by compressing his body to certain degrees. He is also armed with metallic gauntlets that are equipped with retractable blades and wrist-mounted guns.

While serving time in prison, Basil encountered Boss Giovanni and became enlisted in the Cobalt Brotherhood after managing to break Giovanni and his subordinates out from prison. Following a botched gold heist that was thwarted by the Mighty Mutanimals, Basil agreed with his cohorts that the best way to combat the heroic mutants would be to become mutants themselves. As a way of paying tribute to his favorite poet, Edgar Allan Poe, Basil decided to be mutated into a raven but was instead mutated into a crow due to Miguel Calavera putting the wrong kind of DNA into the mutagen the former exposed himself to, much to Basil's annoyance. As Crowhead, Basil possesses the power of flight and sharp claws and talons for close-range combat.

Dropping out of college since his only source of income for tuition (his father's shares of stolen money from the Brotherhood's heists that he sent to Miguel to pay for his education) was gone, Miguel turned his talents to building devices that would aid the Brotherhood in their crimes. Following a botched gold heist that was thwarted by the Mighty Mutanimals, Miguel agreed with his cohorts that the best way to combat the heroic mutants would be to become mutants themselves, which led to him using some mutagen laced with black widow DNA to mutate himself into a deadly mutant spider with a venomous bite, the ability to stick and crawl onto various surfaces and attack foes using four sharp appendages sprouting from his back, and the power to generate webbing from his hands, mouth and backside.

Somehow learning of Xever's reputation, the Shredder had the Brazilian thug freed from prison and recruited into the Foot clan as their street operative who would perform some of the "dirtier" jobs for the Foot that required Xever's criminal expertise. Upon Shredder's discovery that his enemy Hamato Yoshi had taken refuge in New York City, Xever was assigned to aid his partner and rival Cris Bradford in finding and ending Splinter and his clan, only to face defeat at the hands of the Ninja Turtles after venturing into the sewers to capture them, then again after trying to enlist the Purple Dragons to help them bring down the Turtles for good. Sometime later, in an attempt to redeem themselves for their past failures, Xever and Bradford ambushed the Turtles while they were trying to diffuse a mutagen bomb constructed by the Kraang, an attempt that ended disastrously for the two villains after Bradford thrusted his sword into the mutagen bomb and doused the duo with mutagen, which caused Xever to mutate into a deadly mutant snakehead fish with venomous teeth (a mutation that was partially due to Xever holding a fish of the same species he had bought earlier that same night for dinner). Because his mutation cost him the use of his legs (which had been merged together into a tail fin) and eliminated any possibility of leaving any body of water without suffocating and dying, Xever was left confined within the aquarium of Shredder's throne room until the villainous scientist Baxter Stockman, who had accidentally thwarted one of the Foot's attempts at beating the Turtles and was summarily coerced into working for the Foot for his interference, allowed Xever to regain his fighting skills by building him a pair of powerful robotic legs and a breathing harness that would allow him to survive out of water. After the ordeal with Kavaxas, Xever had enough of all the madness that came with the Foot Clan, and decided to abandon it in turn for a simple life of Crime.
  • Baxter Stockman (Phil LaMarr) - An insidious and intelligent mutant housefly and mad scientist and the scientific genius of the Foot Clan. Possessing a gifted intellect but also an unethical personality, Baxter Stockman's first act of villainy was during his childhood when he brought a plastic volcano project that contained real lava to his school science fair, which resulted in the school's gymnasium being burnt down and Baxter getting expelled. As an adult, Baxter attempted to put his brilliance to good use by getting a job at T.C.R.I., only to be fired over an incident that involved a copier machine breaking down and ejecting ink. Having been mistreated all his life by his classmates and co-workers, Baxter snapped and swore revenge on those who wronged him, driving him to create a poorly-made suit of powered battle armor he used to try to break into the T.C.R.I. building, only for him to meet defeat at the hands of the Ninja Turtles. While receiving from the battle, Baxter came across Donatello's recently-created T-pod, a music player equipped with a highly advanced A.I. microchip, and plugged it into his armor, causing it to upgrade into a more powerful battle suit that allowed him to easily vandalize his former office and overpower the Turtles in their second encounter with Stockman. In a third fight against Stockman however, the turtles managed to gain the upper hand against the inventor by shoving a beehive into Stockman's face and eliminating the T-Pod, leaving Baxter defeated, riddled with bee stings and stuffed in a dumpster. Some time after his defeat, Stockman built a new group of small, dinosaur-like robots called M.O.U.S.E.R.S (an acronym for Mobile Offensive Underground Search Excavation & Retrieval Sentries) which he used to steal various loot and electronics in hopes of making himself rich. Unfortunately, Baxter's new venture caused him to come into conflict with the Purple Dragons after his M.O.U.S.E.R.S made off with some of their loot, yet he was able to spare himself from punishment at the hands of Dogpound by mentioning his robots were already working on eliminating the Ninja Turtles. Recognizing the value of Baxter's mechanical expertise, Dogpound coerced Baxter into helping hack into a cell phone that was stolen from April O'Neil, only to be thwarted when the Turtles managed to reprogram the M.O.U.S.E.R.S into attacking their foes and destroying the phone. Though displeased at Baxter for his interference in the Foot Clan's affairs, the Shredder decided to spare the meek scientist so that he could help Xever Montes (who had recently been transformed into a mutant fish during a fight against the turtles that left him unable to leave any body of water without facing the risk of death by asphyxiation) regain the ability to walk and fight on dry land. With the help of some stolen Kraang technology given to him by Shredder's daughter Karai, Baxter was able to construct a pair of powerful robotic legs that, coupled with a water-breathing rig he had also built to prevent Xever from suffocating on dry land, allowed Xever to regain his ability to walk and fight on dry land. Despite his success, Baxter was treated with little to no respect by Dogpound and Fishface (a nickname given to the mutated Xever in his fist battle against the Ninja Turtles as a mutant) and attempted to destroy them and the Turtles in a booby-trapped underground maze he constructed as a trap for the Turtles, only to fail when the Turtles, Dogpound and Fishface joined forces to escape the maze and defeat Baxter's robotic "Monster of Doom", yet he was able to escape at the last minute. He was mutated into a fly for awhile during his time with the shredder, only to be demutated by Michelangelo. Eventually Stockman gains the ability to switch between forms, similar to Karai. After the ordeal with Kavaxas, Stockman, finally finding his voice decides to abandon the Foot all together with Fishface and Tiger Claw.
  • Anton Zeck/Bebop (J.B. Smoove) - An eccentric mutant warthog and the master thief of the Foot Clan. An international super thief outfitted with a high-tech suit, Anton Zeck gained the ire of his employer Ivan Steranko after shooting out the Russian criminal's right eye, though Zeck insisted that he did not do it on purpose. In an attempt to get back on his boss' good side, Zeck agreed to steal Shredder's sacred helmet, the Kuro Kabuto, so that Steranko would forgive him for his past misdeed, only to fail due to the interference of the Ninja Turtles. Several months after this venture and the invasion of the Kraang, Zeck (who had taken up shelter with Steranko after the malfunctioning invisibility mechanism of his suit rendered him unable to escape the city undetected) and Steranko decided to hunt down the mutated Karai in hopes of using her as a means of convincing Shredder to help them get out of the ravaged city, only to thwarted again by the Ninja Turtles and left at the mercy of the infuriated Shredder. Despite Zeck's pleas to be spared out of fear of being mutated and losing his "good looks", Shredder had Baxter Stockman mutate the master thief into an anthropomorphic warthog with an enhanced sense of smell, a mutation that also caused parts of his suit to break apart and merge into his flesh. Aside from his expert infiltration skills as a thief and his unusual yet effective dance-like fighting style, Zeck is outfitted with a special suit (that merged with his body while he was mutated) equipped with various gadgets to help him in his heists, which include a cloaking mechanism that allows him to turn invisible, a belt with hip-mounted blasters, a pair of gloves equipped with laser blasters that can be used used to cut holes in glass or take out enemies from a distance, a backpack that allows him to slide up or down vertical surfaces, a pair of boots that can generate a pair of energy beams Zeck can ride on to get from one place to another, and a mohawk that can generate explosive mohawk-shaped bolts of energy.
  • Ivan Steranko/Rocksteady (Fred Tatasciore) - A powerful mutant rhino and the artillery expert of the Foot Clan. Hailing from Soviet Russia, Ivan Steranko was once a notorious weapons dealer and artifact collector, as well as a longtime acquaintance of the Shredder. Eventually coming to desire Shredder's legendary helmet, the Kuro Kabuto, Steranko ordered his subordinate Anton Zeck to steal the helmet to add to his collection of famous artifacts, promising to forgive Zeck for shooting out his right eye if he succeeded, only for Zeck to fail due to the intervention of the Ninja Turtles. Several months following this failure and the invasion of the Kraang, Steranko and Zeck decided to hunt down the mutated Karai to use her as a means to convince Shredder to help them get out of the ravaged city, yet were thwarted once more by the turtles who allowed Karai to escape and left at the mercy of the infuriated Shredder. Despite Steranko's attempts to use their acquaintanceship as a way to convince Shredder not to have him mutated and his insistence that he would be more useful to the latter as a human instead of a mutant, Shredder had Baxter Stockman mutate the unwilling Steranko into a large, immensely strong mutant white rhinoceros, a mutation that caused most of Steranko's outer clothes to burn away while also melting his metal shoulder pads and knuckle busters into his flesh.
