Characters
Allies Villains
 * Mighty Mutanimals
 * Leatherhead (Peter Lurie) - Leader of the Mighty Mutanimals. Like Professor X from the X-men and Goliath from Gargoyles, he hopes for a peaceful future between man and mutantkind.
 * Spike/Slash (Corey Feldman) - Enforcer.
 * Newtralizer "Newtie" (Danny Trejo) - Weapons specialist. After that betrayal with Slash, he comes to his senses and apologizes to him and swears to put people first, though he still has some temper problems.
 * Martin Milton/Sir Malachi (Paul Reubens) - Diversion Artist and Mystic. He has somehow gained legitimate magical powers.
 * Dr. Tyler Rockwell (Frank Welker) - Acrobat. He can now speak
 * Valerie Zuari/Fastcat (Cree Summer) - Runner. A new character who was formerly a homeless African American teenager before being mutated by the Kraang into a mutant cheetah with superhuman speed, reflexes, agility, night vision, and a prehensile tail. She seems to have a crush on Slash and flirts with him regularly.
 * 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 because they enjoy teasing him with it. He is given a pair of shoulder-mounted laser blasters by Mousepad.
 * Mondo Gecko (Ben Schwartz) - Infiltration expert. He is about 14 in human years and can stick to/climb up walls and ceilings. His main weapons are a pair of escrima sticks and kunai throwing knives.
 * Mousepad (Sarah Hayland) - Tech Operative. She is an albino mutant mouse with superhuman intelligence and limited technopathic abilities. She has been in Dimension X before and has stolen Kraang data and weapon blueprints to use against them. She also has a crush on Mondo Gecko.
 * Walkabout (Jennifer Hale) - Tracker and combat specialist. A female mutant red kangaroo with an Australian accent that was stolen from the Bronx Zoo and mutated by the Kraang in hopes of using her as a weapon against the TMNT. After the MM rescued her, she was grateful and agreed to join them as their tracker and combat expert. Being a kangaroo, she posessess immense strength in her lower body, allowing her to deliver powerful kicks and leap great distances, as well as using her tail as a third hand or an offensive weapon. She is also a skilled boxer, but often employs gimmicked boomerangs an bolas (which are hidden in her pouch) to take down enemies at a distance. Despite the fact that he could probablt eat her, Walkabout shares a mutual attraction to Leatherhead. She doesn't usually let any of her smaller teammates (like Mousepad, Malachi and Mondo) ride in her pouch because she is very ticklish in there, but she likes it anyway and thinks it feels nice.
 * Hardrock (Curtis Armstrong) - Excavation. A mutant armadillo
 * Screwloose (Max Casella) - Scout. A mutant mosquito and the only other member of the MM who can fly. He is very similar to Daxter from the Jak and Daxter video games, which is ironic since both characters are voiced by Max Casella.
 * Screwloose Flynn the Fnn (Richard Steven Horvitz) - Underwater operations. An unusual young blue-skinned amphibious creature hailing from Dimension X, Flynn (as he named himself) followed Leatherhead into the human world and decided to join the MM as their diver and operator. He can swim fast, breathe underwater, and control water and generate electricity. His skin is slippery and makes him hard to grab, and he can even inflate himself like a puffer fish to become stronger. He wields a trident as a weapon and looks up to Leatherhead. He somewhat resembles Tramm from Teen Titans
 * Conway Higgins (Logan Grove) - The MM's friend after they saved him from the Kraang who kidnapped his mother Bianca.
 * Jack Finney/Man Ray (Xander Berkeley) - A former environmentalist and oceanographer who discovered the sunken Technodrome while taking a ride in his submarine. He was captured by the Kraang and mutated into a mutant manta ray.
 * Marlene Atkins (Mae Whitman) - Conway's girlfriend and big fan of Sir Malachi.
 * Ignatius (Dante Basco) - Conway's best friend. He seems to be aware of the MM's existence.
 * Bianca Higgins (Grey Delisle) - Conway's mother and Kirby's partner and girlfriend. She is mutated into a butterfly by the Kraang.
 * Sally Cooper (Jessie Flower) - A mutant chipmunk and ally to the MM. She seems to have a crush on Malachi and flirts with him constantly. She is Marlene's best friend.
 * Bentley Masters (Rickey D'Sohn Collins) - The Mighty Mutanimals' first enemy. He makes his first appearance in The Pilot. He is a African American master thief from a long line of thieves. He is eventually defeated when Sir Malachi freezes him in solid ice. A running gag is the Mighty Mutanimals forgetting his name or misspelling it on purpose, annoying him to no end. He is a recurring villain.
 * Perry Barnes (Jeff Bennett) - The MM's second enemy. He appears in the second episode "Times Change. He is an anthropomorphic Chameleon and a master of disguise. He tried to infiltrate the MM but Leatherhead figured out his ruse. He is later thrown into a laundry chute.
 * Jay O'Neil (David Kaufman) - April O'Neil's evil cousin who became the MM's archnemisis and constantly tries to destroy them. A running gag is that the MM and other villains never take him seriously partly due to his name and partly due to his hunched back and permanent high pitched squeaky voice from a helium accident. He is the Baxter Stockman of the MM. He seems to have a high IQ shown when he created a robot suit. His aunt is always turning a blind eye to him but seems to be aware that he's evil. He appears in "I Think His Name's Jay O'Neil". The MM always throw him in the trash after they defeat him. He is mutated into a flying fish by Skipper McFingers.
 * Carmelita Elyers/Raptora (Nicole Sullivan) - A mutant vulture and elusive thief. She is always eluding the police due to her mutation. Pete has a crush on her. He defeats her by tricking her into a birdcage. She appears in "Pete in Love". It is implied that Pete still has feelings for her. She is the first female villain the MM ever face as well as the first mutant villain. Newtralizer, Slash, Leatherhead, Malachi, and Rockwell seem to enjoy teasing Pete about his feelings for Raptora.
 * Fishy Galore (Jack DeSena) - Fishface's son.
 * Penelope Sergeant (Jennie Kwan) - Fishy Galore's girlfriend.
 * Skipper McFingers (Jonathan Adams) - An African American mobster who works for the Kraang. It is revealed that he was responsible for the death of Conway's father. He appears in Newtralized Temper. He is defeated by Leatherhead. He mutates himself into a Gorilla.
 * Toxin (Carlos Alazraqui) - An mutant poison dart frog
 * Norton Gibbs/Flipper (Tara Strong) - A young mutant penguin who hates adults because he was unable to grow up. He appeared in Child's Play. He tried to turn everyone into kids because if he couldn't grow up no one could. He was defeated by the MM and magically turned into an adult by Malachi. He presumably reformed because of this.
 * Buttercup (Thomas F. Wilson) - A large mutant bulldog. As a running gag, the MM would laugh at his name.
 * Mutant Master (Mark Hamill) - An enemy more dangerous then both Kraang Prime or the Shredder. He is a supermutant, with the power to create mutants in his image and control them. He believes that he is doing what is best for the world, making a new world order, evolving humanity to mutanism, no ugliness and no pain.
 * Larry Shelton (Alex Polinsky) - A teenage mutant vampire bat and treasure hunter. He found some mutagen and allowed a bat to bite him so he could mutate himself.
 * Vincent Jeremiah/Voltor (Armin Shimmerman) - A mutant electric eel
