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 5 years after the series finale of TMNT 2012, the Turtles learn about huger enemies, more evil and stronger than the Shredder or the Kraang. And so, they decide to team up some allies and some former enemies to help them take down this force before it destroys them all.

The Mighty Mutanimals

 * Slash (Corey Feldman) - Leader of the Mighty Mutanimals. He and Newtralizer have a Leo and Raph arguable relationship.
 * Leatherhead (Peter Lurie) - Enforcer. He hopes for a peaceful future between man and mutantkind.
 * Newtralizer (Danny Trejo) - Weapons specialist and second-in-command. After his betrayal, he has gained a new energy form from the teleporter which made him stronger; invincible to any damage. He sees how heartless he was and promises to put humans first, if it means defending the city from evil. He is often partnered up with Slash.
 * Sir Malachi (Paul Reubens) - Diversion Artist and Mystic. He has somehow gained legitimate magical powers ever since his encounter with the Turtles.
 * Dr. Tyler Rockwell/Monkey Brains (Tom Kenny) - Acrobat. With a device Donnie created, he can now speak and he sounds like Gibson from the "Super Robot Monkey Team Hyper Force Go!" cartoon series. He acts as the brains for the team, coming up with logical solutions and providing information. By the time the Mutanimals were formed, Monkey Brains' psychic abilities had evolved from simple emotion reading to full-on telepathy, telekinesis, and clairvoyance. Having these newfound powers, he sets 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).
 * Pete The Pigeon (A.J. Buckley) - Aerial Specialist. 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 he joined the Mutanimals, he was given a pair of shoulder-mounted laser blasters by Donnie.
 * Mondo Gecko (Robbie Rist) - A mutant lizard skateboarder and Candy Fine's boyfriend. He owns a rocket-powered skateboard which he uses to travel around the city. His weapon of choice is a pair of kama.

Allies

 * The Ninja Turtles:
 * Leonardo/"Leo" (Seth Green) - The Leader.
 * Donatello/"Donnie" (Rob Paulsen) - The Brains. He has a massive crush on April O'Neil and is the one who founded the Mutanimals.
 * Raphael/"Raph" (Sean Astin) - The Muscle. Slash's former owner.
 * Michelangelo/"Mikey" (Greg Cipes) - The Wild One. Leatherhead's first mutant friend.
 * April O'Neil (Mae Whitman) - The half-human/half-Kraang teenager. She trains Candy in the art of ninjutsu, like Splinter before her.
 * Kirby O'Neil (Keith Silverstein) - April's dad and the mutant formerly known as Kirby-Bat.
 * Casey Jones (Josh Peck) - Street-banging vigilante and Raphael's best friend.
 * Hamato Yoshi/Splinter (Hoon Lee) - The turtles' sensei.
 * Candy Fine (Stephanie Lemelin) - Mondo's rebellious girlfriend. She trusts the Mutanimals with her life and is Casey's cousin. She was originally a Foot Clan kunoichi, but was banished due to her rebellious nature. After her banishment, she became a roller derby player, which gave her great skill on rollerblades. After accepting training from April, she was given a pair of escrima sticks for combat. She loves Mondo for who he is, and is good friends with the other Mutanimals and Jesse.
 * Jesse the Creeper (Dante Basco) - Casey's childhood friend who was thought to have perished in a fire caused by the Purple Dragons; when in reality he survived and swore vengeance against them. He was also given permission from Mondo to become Candy's boyfriend should he ever die in battle.
 * Angel (Cree Summer) - Casey's childhood friend from the ghetto. She originally worked for the Purple Dragons, but then joined the Mutanimals after she rescues them from a Purple Dragon ambush.
 * Carter (Shawn Harrison) -
 * Rebel Triceratons:
 * 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. While searching New York one night to find a way to gain the upper hand against the Kraang, Traximus observed a brawl between a Kraang battalion, the Ninja Turtles and the Mutanimals and decided that the mutants would make valued allies in their war against the Kraang. After proposing this idea to his superiors, Traximus was given the task of making first contact the mutants and bringing them to Dimension Z after gaining their trust, the former which he completed by aiding the good mutants in fending off a Kraang ambush. After building a friendship with the mutants (particularly Michelangelo despite their greatly opposing personalities), Traximus escorted his new acquaintances to Dimension Z only to unwittingly lead them into an ambush where they were knocked out and captured, though Mikey managed to escape. Confronting his superiors about the ambush, Traximus was appalled to discover that they intended to brainwash the Turtles and Mutanimals into serving them instead of simply asking for allegiance as previously suggested by Traximus. While heading back to his quarters in remorse, Traximus ran into Michelangelo who, while furious at the former’s involvement with the current ordeal, understands that it was never his intention for the current situation to turn out and offers him a chance at redemption, which Traximus takes. After freeing his mutant friends and opening the portal to Earth, Traximus implores his girlfriend Alathea to leave with them to help fight the Kraang on their own, but she refuses, instead choosing to remain in Dimension Z to provide Traximus and the Mutanimals inside intel on the Triceratons’ operations. When they all return to Earth, Traximus departs, but not before being labeled an honorary Mutanimal by Slash. 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.
 * Alathea (Cricket Leigh) - Seemingly the only female member of the Triceraton army, Alathea is a young yet very skilled warrior whose agility and skills with a spear make her a formidable opponent, though she is mostly favored as a scientist for the army. 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.
 * Monza Ram (Jason Spisak) - The former leader of the Triceraton All-Star Team and Traximus' friend.
 * Trobec (Yuri Lowenthal) - A former member of the Triceraton All-Star team.

 * Ace Duck (Jeff Bennett) - A mutant duck and the pilot for the Turtle Blimp. He used to work for the Foot Clan before he joined the Mutanimals and their allies.
 * Renet (Ashley Johnson) - The current Master of Time, and the object of Michelangelo's amorous affections. She can control time at her will, and guards a sacred relic known as the Scepter of the Sands of Time from the Savanti sorcerers: Romero and Juliet.
 * Scale Tail (Kelly Hu) - A mutant serpent that is later revealed to be Karai, Splinter's daughter.
 * April Jones (Megan Fox) - April 20 years into the future. She's married to Casey, and is now an agent for the EPF (Earth Protection Force). She still remains an ally to the Turtles and Splinter.
 * Commander Jason Bishop (Chris Cox) - The commanding officer of the Earth Protection Force's Black Squadron. He will do anything to protect the Earth from hostile alien forces from otherworldly dimensions.
 * The League of Mutants:
 * King Lionheart (Kelsey Grammer) - The leader of the LOM, he was once a Shakespearean actor that got mutated by the Kraang into a lion. After the Mutanimals bust him out of a Kraang prison, he joins their cause for battle. He uses a steel-tipped sword and protects himself with his fireproof shield.
 * Halfcourt (Chris Rock) - A mutant giraffe with a basketball player motif and an ally of the the Mutanimals. His air pump gun is his main weapon, along with his endless supply of basketballs.
 * Sandstorm (Brian George) - A mutant dromedary from the sands of Saudi Arabia and Halfcourt's half-cousin. His diamond lamp can grant him anything he desires. His diamond lamp also works as a pistol, gunning down any Kraang in his way. He also carries a scimitar, but he rarely uses it.
 * Monty Moose (Dave Thomas) - A mutant moose with a Canadian Mountie motif who joins the LOM after the Mutanimals free him from a Kraang prison. He relies on his sword and revolver.
 * Sergeant Bananas (R. Lee Erney) - A mutant gorilla. He was formerly a drill sergeant in the Vietnam War named Sergeant Emmett Patton. While leading an attack on an enemy base, Patton was separated from his platoon and stumbled upon a secret laboratory that belonged to the Triceratons. He was discovered, captured, and used as a guinea pig for the Triceratons' mutagen experiments, which mutated him into his current apelike form after he was doused with mutagen that was mixed with some gorilla DNA. Despite being held captive for years, his will would not break and he eventually escaped to seek retribution against the Triceratons. After the Mutanimals bust him out of a Kraang prison, he swears a lifetime of gratiude and joins the LOM. He relies on his brute strength and huge, hairy fists.
 * Hot Spot (Josh Keaton) - A mutant dalmation who was once the pet of a Chinatown firefighter. He joins the LOM after the Mutanimals rescue him from the Kraang prison. He owns a handheld pressurized water cannon.
 * Dr. El (Jonathan Adams) - A mutant elephant and voodoo witch doctor. Originally from Africa, he got captured and later mutated by the Kraang into an elephant. He later joins the LOM after the Mutanimals rescue him from the Kraang prison. He uses black magic to win his battles.
 * Russell "Russ" Gregory/Walkabout (James Patrick Stewart) - A mutant kangaroo. Originally named Russell "Russ" Gregory, he was once a dedicated game warden and professional outdoorsman who kept a vigil watch over the Australian wildlife preserve he worked at. One day, after reuniting a kangaroo joey with its family, Russell was abducted by the Kraang and unwillingly mutated into a kangaroo (since the joey's DNA was still on his person when he mutated). After doing hard time in the Kraang's mutant prison, he was freed by the Mighty Mutanimals and took on the name "Walkabout" before joining the League of Mutants. Because of his mutation, Walkabout possesses great strength in his lower body, allowing him to leap great distances and can deliver powerful kicks. He uses two boomerangs and a hunting knife.
 * Panda Khan (Lauren Tom) - A female mutant panda martial artist. Formerly an inhabitant of the Bronx Zoo, she was abducted and mutated by the Triceratons. She had the knowledge of different martial arts (namely karate, jujitsu, judo, samurai and kung fu) implanted into her mind, making her a master of hand-to-hand combat. Personality-wise, she is a kindhearted individual with a strong sense of compassion, and is often the first one to put her life on the line to protect the innocent.
 * Mousepad (Lacey Chabert) - A mutant mouse. 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. After being mutated by the Rat King to act as a "mentee" in his quest for world domination, she 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 the mouse's hands. Out of desperation, Sir Malachi smooth talked the mouse 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.
 * Wingnut (Richard Steven Horvitz): Originally an ordinary fruit bat residing in the Bronx Zoo with Panda Khan, Wingnut was abducted by the Kraang and used as a test subject for their mutagen experiments, an experience that drove him to madness. Despite his insanity, Wingnut retained a kind spirit and swore to avenge himself for what the Kraang had done to him. Befriending the mutant mosquito Screwloose, the two formed an unorthodox yet dedicated crime-fighting duo to combat the Kraang menace. He can fly, has sharp claws to fight with, and can emit sonic screams.
 * Screwloose (Max Casella) - A mutant mosquito. Originally an ordinary mosquito, he was captured by the Kraang and doused with mutagen with human DNA in it, turning him into his current state. He is a wisecracking, likeable mutant who claims to be a fearless and formidable opponent to the Kraang, but he is usually the first one to flee in the face of danger.
 * Cactus Butt (David Spade) -
 * Hardrock (Curtis Armstrong) - A squat, pugnacious but good-hearted and charming mutant armadillo with a passion for demolitions and explosions. Being an armadillo, he can curl up into a nigh-indestructible ball that can roll around at high speeds and ricochet off walls (like Cannonbolt from Ben 10). In combat he uses his sharp claws and numerous homemade explosives. He is dressed in black pants, black gloves, and blue goggles.
 * Mrs. Jones (Rena Sofer) - Casey's long-lost mother.
 * The Punk Frogs: A tribe of mutant frog warriors who reside in the forests outside of New York.
 * Attila the Frog (Maurice LaMarche): The stern but fair leader of the Punk Frogs. Thanks to some advice by Sir Malachi and Mousepad's genius, he gains a powerful mace as a weapon.
 * Genghis Frog (Kevin Michael Richardson): The former general of the frog army and the most aggressive member of the Punk Frogs, though he still respects Attila's leadership. Thanks to some advice by Sir Malachi and Mousepad's genius, he gains a battle axe as a weapon.
 * Rasputin the Mad Frog (Maurice LaMarche): Attila's advisor and right-hand frog and the resident genius of the Punk Frogs. Thanks to some advice by Sir Malachi and Mousepad's genius, he gains a bow and quiver of custom arrows as weapons.
 * Napoleon Bonafrog (Jon Heder): The youngest member of the Punk Frogs and the current general of the frog army. Thanks to some advice by Sir Malachi and Mousepad's genius, he gains a bullwhip as a weapon.

Enemies

 * Mutant Master's Army
 * Mutant Master (Mark Hamill) - The self-proclaimed ultimate mutant who can turn anyone he touches into a mutant under his command and the primary antagonist of the series. He plans to turn all the people in the world into mutants so he can be the supreme mutant.
 * Cap'n Mossback/Crabcake (Jim Cummings) - Mutant Master's second-in-command. Originally a shrimper from New Orleans, he joined Mutant Master for $45,000. Due to his constant failures to destroy the Mutanimals, he gets mutated into a crab in "Mossback and Mutants Don't Mix".
 * Road Hog (Harland Williams) - The "Mighty Mutanimals" incarnation of Bebop; a bumbling, leather-wearing mutant pig biker who, while a subordinate of Mutant Master, is a rather positive, humorous and optimistic mutant who genuniely believes Mutant Master is helping the world by mutating it, though he is not above helping the Mutanimals if the situation demands it. He is also a very skilled mechanic, having built his weaponized motorcycle and modifying other vehicles with weapons and whatnot.
 * Santiago Delgado/El Hippo (J.B. Blanc) - The "Mighty Mutanimals" incarnation of Rocksteady; a mutant hippo. 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 alliegence 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 hippopotomas, and took on the name El Hippo after extracting revenge on his enemies.
 * Cyber Samurai (Peter Jessop) - The "Mighty Mutanimals" incarnation of Chrome Dome; an intelligent yet slinky, skinny robotic samurai created by Adrian Stockman to serve Mutant Master. He is equipped with wings for flight, laser eyes, space-age armor, rocket fists, and an energy sword.
 * Jemarcus DeCosta/Dreadmon (Dave Fennoy) - The "Mighty Mutanimals" incarnation of Chris Bradford/Dogpound/Rahzar; a mutant wolf. 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 jumping from country to country. While in New York after successfully stealing a rare diamond, Jamarcus 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 Marques/Terrorcuda (Billy West) - The "Mighty Mutanimals" incarnation of Xever/Fishface;.
 * Adrian Stockman/Megamoth (Dorian Harewood) - Baxter Stockman's cousin. He is composed, respectable, eloquent, sardonic; everything that Baxter wasn'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.
 * Old Hob (Steven J. Blum) - A mutant cat who acts as the commanding officer for Mutant Master's army of mutants.
 * Mutagen Man (Roger Craig Smith) - The Turtles' ex-biggest fan.
 * Jack Finney/Man-Ray (Xander Berkeley) - A mutant manta ray. Originally named Jack Finney, he was once a dedicated oceanographer and environmentalist who worked hard to protect the ocean he so deeply cared for. While out on his boat late one night to rescue a manta ray from a fishing net, Jack was struck from above by a lone canister of mutagen (one of the many that were lost during the events of The Mutation Situation) and mutated into an anthropomorphic manta ray with superhuman strength, underwater breathing, powerful swimming speed, limited flight, electricity projection from his tail, and telepathic control over marine life. 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.
 * Boss Hugo Giovanni/Oranguton (Maurice LaMarche): 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.
 * Natalie Gates/Queen Bee (Tara Strong) - Natalie Gates was formerly a teenage melittology (beekeeping) student and a classmate of Candy Fine’s who suffered constant maltreatment and mockery at the hands of her High School cheerleading captain Melissa Doyle, leaving her in a seemingly perpetual irritable and surly disposition. After a particularly cruel prank was pulled on her during her school’s homecoming dance (in which one of her own beehives was dropped on her head), Gates went off the deep end and swore revenge on those who wronged her, creating a weaponized bee-themed costume and taking to the skies as the highly vindictive and waspish vigilante named Queen Bee.
 * Buttercup (Thomas F. Wilson) -
 * Savanti Romero - The former apprentice of Renet's father, he plans to obtain the Scepter of Time so he can control all time.
 * Savanti Juliet (Lauren Tom) - Savanti Romero's sister, she works with Romero to obtain the Scepter and rule all time.
 * Clown Frown - A mutant clown/demon hybrid, he penetrates the dreams of people while they're asleep and takes on the form of their worst fear.
 * Victor Falco/Rat King (Jeffrey Combs) - A ruler of rats and a major enemy of the Mutanimals, the Turtles and Splinter. He fell into some sewage water after his long fall and swore vengeance against Splinter and the Turtles, vowing to rule the city.
 * The Squirrelanoids: The result of an average squirrel innocently consuming the contents of a broken mutagen canister would be perhaps the most horrifying mutants yet created. Originally possessing the power of self duplication while inside a host's stomach, an encounter with the Ninja Turtles granted said squirrels a more monstrous appearance after they used Raphael as a host; the teenage terrapin's mutated blood transforming them into horrific, skeletal, red-furred abominations with immense strength, speed, agility, sharp claws, and a prehensile tongue.
 * Foot Clan
 * Oroku Saki/Shredder (Kevin Michael Richardson) - The leader of the Foot Clan and Splinter's archenemy.
 * Tiger Claw (Eric Bauza) - Shredder's second-in-command. He gains a cybernetic eye to replace his missing one, allowing him to see in infared vision.
 * Rahzar (Clancy Brown) -
 * The Kraang (Nolan North) - Aliens from Dimension X with dreams of taking over Earth. Leatherhead's archenemies.
 * Triceratons - Alien race of anthopomorpic triceratops who are the Kraang's rivals in world domination. They originate from Dimension Z, which has an atmosphere similar to Dimension X's, but not as toxic.
 * Zanramon (Tony Todd) - The emperor of the Triceratons.
 * Commander Mozar (Kevin Grevioux) -
 * Netherdead (Peter Lurie) - Leatherhead's dark clone. Created by the Kraang.
 * The Insane Mutant Rejects
 * Bloodsucker - Their leader, a mutant leech. He doesn't speak, and communicates through telepathy, which is translated by Armaggon.
 * Armaggon (Steven J. Blum) - Second-in-command, a mutant shark from the future.
 * The Racy Vest-Wearing Monkey (Frank Welker) - A mutant gorilla. Gets very vicious when someone calls him a "racy vest-wearing monkey" (which is kind of ironic, considering that it his name).
 * Ramhorn (Fred Tatasciore) - A mutant ram. Is very agressive towards his teammates, but he still respects them.
 * Count Rattington (Tim Curry) - A mutant rat. Dressed like Alex from Stanley Kubrick's "A Clockwork Orange".
 * Insectoid (Dee Bradley Baker) - A mutant insect. His insanity is at a maximum level, making him a very dangerous enemy.
