Ninja Turtles[edit]

• Raphael (voiced by Omar Benson Miller^[1]) – A 15-16-year-old (17-18 in the movie) Alligator snapping turtle and the oldest brother of the group; before the second-season finale, he was the team's leader, and he informally named themselves the "Mad Dogs". Zane formerly wields two tonfa in a battle that can amplify his own physical strength with red mystical energy constructs and he had been given new sais in the season two four-part finale with the ability to make clones of himself made from the same energy.^[2] He has a habit of speaking in the third person in battle. Zane has numerous catchphrases: "Jumpin' Jackflash" when surprised, "Hot Soup" as a battle cry and "Power Punch-Jitsu" when using his tonfas.

• Leonardo (voiced by Ben Schwartz^[1]) – A 14-15-year-old (16-17 in the movie) Red-eared slider, and the team's current leader as of the Season 2 finale. He is known as the trickster of the group and thinks that his one-liners will "fire up the team", but is shown to have actual encouraging charisma. Leo wields an ōdachi sword in a battle that can open portals, but he had been given new katanas in the season two finale that allows him to teleport himself or others.^[3] Despite coming off as arrogant, Leo has an insecure side and feels a need to always be right. By the end of the four-part "Finale" episodes, Splinter makes Leo the new leader of the group.

• Donatello (voiced by Josh Brener^[1]) – A 14-15-year-old (16-17 in the movie) Soft shelled turtle, is the "genius of the team" and relishes praise from others. He has a sidekick drone named S.H.E.L.L.D.O.N. along with many battle shells that he makes to help him in battle because of his species. He rejects claiming a magical weapon like his brothers and instead wields a high-tech version of his traditional bō staff in a battle that can transform into a multitude of weapons like drills or a rocket-powered hammer. This was destroyed near the end of season two and was replaced with a mystic bō staff with magic energy versions of his gadgets. The new mystic staff could also link up with his technological attachments.^[2]

• Michelangelo (voiced by Brandon Mychal Smith^[1]) – A 13-14-year-old (15-16 in the movie) box turtle who is the youngest jokester, prankster brother. He is an affectionate and sensitive artist, and is also called the wild card of the group. Mikey wields a kusarigama in a battle that can become a fire spirit, but he had been given a new set of nunchaku in the season two finale with the ability to extend to great length and control will.^[4]

Allies[edit]

• Hamato Yoshi / Splinter (voiced by Eric Bauza^[1]) – Splinter is a mutant gray rat who is the Ninja Turtles' sensei and father. He is fond of watching the projects of Lou Jitsu, milk, and cake. His training of the Turtles manifests in copying and watching Lou Jitsu tapes, which is revealed to be more effective than the brothers expected. In "The Evil League of Mutants" and "Shadow of Evil", Splinter is revealed to be Hamato Yoshi as he neglected to carry out the Hamato Clan's mission in preventing Shredder's return by working in Hollywood under the stage name of "Lou Jitsu", and in the four-part "Finale" revealed he resented his family's mission to it forcing his mother to leave him while he was young. He acquired a large fanbase during his career including Baron Draxum, who used his genetic sample to create the Turtles, and some members of the Foot Clan. The flashback sequences of "Many Unhappy Returns" and "Goyles, Goyles, Goyles" reveal how Yoshi was abducted by Big Mama to fight in the Battle Nexus and his later mutation, from being constantly bitten by a rat, while Draxum used his DNA to create the Turtles.

• April O'Neil (voiced by Kat Graham^[1]) – An African-American human friend of the Ninja Turtles, she has already known them for 5 years before the beginning of the show and the turtles look to her as an older sister figure.^[5] April is a fun-loving virtuous, if tomboyish, girl with glasses who is constantly looking for a job to support herself which constantly goes wrong. "Hypno: Part Deux!" shows that despite her bravado, she has a hard time making friends at school and is nervous about high school gatherings. When fighting, she also wields any blunt weaponry she can find, mostly a baseball bat.^[6] In "Warren & Hypno, Sitting in a Tree", it is revealed that April knows who Warren Stone is as she was part of a fan club dedicated to him called the Stoneheads, and she is 16 years old (later 18 years old in the film). In "Donnie vs. Witch Town", April's bat gets enchanted during her visit to the Hidden City's Witch Town district.

• Baron Draxum (voiced by John Cena in season one,^[7][8] Roger Craig Smith in season two) – A maroon-skinned Yōkai warrior and alchemist from the Hidden City with maroon hair and faun-like legs, who has the power to augment his own body by crushing purple pods in his hands, and can manipulate giant purple tentacle-like vines to grab objects, enemies, or as a means of transportation. As the self-proclaimed protector of all Yōkai, Baron Draxum seeks to mutate humanity to avert a prophecy predicting the destruction of the Yōkai.^[9] An incident amidst an earlier attempt to turn humanity into Yōkai led to the creation of the Teenage Mutant Ninja Turtles while causing Hamato Yoshi's transition into Splinter, attempting to win the former to his side before joining forces with the Foot Clan to reassemble the Kuroi Yōroi and revive Shredder. In "How to Make Enemies and Bend People to Your Will", Draxum exploits a loophole in the Foot's rules to becomes its leader through tactics that enable him to gain a shard of the Kuroi Yōroi that the Foot Lieutenant and Foot Brute failed to acquire. In the episode "End Game", Draxum equips the restored Kuroi Yōroi armor intending to destroy humanity once and for all. The Foot Lieutenant and Foot Brute address him as Shredder, but he rejects the title, confused with the name "Shredder". Due to a Jupiter Jim action figure being wedged in a hole in the back of the helmet, the Turtles managed to attack that part and cause the armor to fall off of Draxum, though the armor is revived after siphoning some of Draxum's life force, degrading his body to nearly a corpse and weakening his powers considerably. After the Foot Recruit emerged from the portal she opened to assist her senseis, Draxum used his weakened abilities to escape through it. In "Repairin' the Baron", Mikey takes in a weakened Draxum and teaches him to tolerate humans with Raph's help. After saving a mother and daughter from the Ferris wheel during Garm and Freki's attempt to capture him at Albeartoland while losing his mask in the process, and slowly starting to regain his lost power, he starts to tolerate humans, after which Raph and Mikey get him a job working at the cafeteria at April's school. In the four-part "Finale" episodes, Draxum realized that Shredder was the threat to the Yōkai mentioned in the prophecy, not humanity.

• Cassandra "Casey" Jones (voiced by Zelda Williams) - First appearing under the alias of the "Foot Recruit", Cassandra Jones is a female member of the Foot Clan with a hyper-aggressive personality who is a gender-bent version of Casey Jones, and debuted in "Hot Soup: The Game". In "How to Make Enemies and Bend People to Your Will", Cassandra assists Baron Draxum in getting a Kuroi Yōroi fragment from a statue in the botanical gardens so that she can be able to move up. In "Battle Nexus: New York", Cassandra was placed on a cruise by Shredder so that Big Mama can make New York into the Battle Nexus. She was the one who found that Big Mama was controlling the Shredder using a control device on him and its associated magic ring. When she claims the magic ring, Cassandra controls the Shredder into destroying the Grand Nexus Hotel as she shouts the Foot Clan's name. When the Shredder regained his power of speech, he promoted Cassandra to the rank of Foot General and had her perform the ritual to drain Splinter's essence. After witnessing Shredder's uncaring for his followers, Cassandra defected to the Turtles' side and helped to defeat the Shredder while revealing her true name to them. The film Rise of the Teenage Mutant Ninja Turtles: The Movie revealed that she is the mother of Casey Jones in the future.

• Casey Jones (voiced by Haley Joel Osment) - Cassandra Jones' son from the future who appears in Rise of the Teenage Mutant Ninja Turtles: The Movie and adheres more to the character's traditional design. He was trained by Leonardo, who sends him back in time to stop the invasion of the Krang. In battle, he wields a hockey stick with a chainsaw attached to one end.

• Hamato Karai (voiced by Gwendoline Yeo) - The founder of the Hamato Clan and the biological daughter of Oroku Saki. After her father became the Shredder, she created the new Hamato Clan and ultimately defeated Shredder at the cost of her being imprisoned in the Twilight Realm with him, since then her clan has been preventing the foot from reviving their master. She ultimately was freed by the Turtles, who call her "Gram-Gram," and managed to channel her essence into April's body to give the Turtles the rightful ninja skills their required through April.

• Mayhem / Agent 64 – An unspecified cat/dog-like creature with short-range teleportation abilities that becomes April's pet.^[10] It is an agent that worked for the Council of Heads against Baron Draxum and was sent to monitor him.

• Todd Capybara (voiced by Thurop Van Orman) – A friendly mutant capybara and selfless charitable proprietor of Cuddles Cakes Puppy Rescue on Long Island. In exchange for Todd giving up his RV, Michelangelo and Donatello build a new type of residence for Todd and his rescue puppies. In "Portal Jacked", Todd has a picture in Run of the Mill Pizza that lists him as a "best customer".

• Señor Hueso (voiced by Eric Bauza impersonating Antonio Banderas) - A skeleton who uses his own left arm for a cane. He is the doorman and manager of the pizza parlor called Run of the Mill Pizza in New York's mystical Undercity. In "Portal Jacked", Senor Hueso has the brother named Capitán Piel. Señor Hueso's name is Spanish for "Mr. Bone".

• Stanley / Bullhop (voiced by Dave Foley) - A Canadian immigrant and bellhop who worked at The Grand Nexus Hotel that was actually a front for Big Mama's Battle Nexus. When the Oozesquitos swarmed in the hotel, the Turtles tried to keep Stanley from getting stung only to fail. As a result of his consumption of beef jerky as noted by Big Mama, Stanley is turned into a mutant bull and flees the hotel. After the Turtles try to make up for their mistake, he becomes their friend and develops advanced dancing skills. This character is a homage to Jerry Lewis' role in the film The Bellboy.

• DIGG - A trio of girl rock musicians longing for their breakthrough. Turned into a mutant burrowing animal by the Oozesquitos during one of their gigs, they attempt a misguided scheme to win themselves an attentive debut audience by targeting the different pizzerias. With the Turtles' aid, they finally become an attraction as pizzeria musicians while also reuniting a family of pizza makers.
  • Prairie Dog (voiced by E. G. Daily) - A mutant prairie dog who is the group's lead singer and guitarist.
  • Ground Hog (voiced by Betsy Sodaro) - A mutant groundhog who is the group's dig-obsessed drummer. She tends to say "dig" when she is burrowing.
  • Honey Badger (voiced by E. G. Daily) - A mutant honey badger who is the group's secondary guitarist. She is the strongest of the group.

• Sunita (voiced by Kody Kavitha) - A slime Yōkai that can explode and reassemble at will. She can assume a human form thanks to a special amulet. At the time of meeting April and the Turtles, Sunita was wearing metal boots that turned out to be a part of the Kuroi Yoroi leading her to be targeted by the Foot.

• Frankenfoot (voiced by Rob Paulsen) - A patchwork Origami Ninja put together by Raph as a sparring partner. He becomes a permanent member of the team, even earning a Mad Dog insignia courtesy of Mikey.

• S.H.E.L.L.D.O.N. (voiced by Greg Cipes) - An A.I. invention that is devoted to its creator Donnie causing a disgruntled Raph, Leo, and Mikey to reprogram and thus inadvertently turning it against their brother. Donnie was able to fix it and it occasionally fights alongside them in the form of a drone.

• Piebald (voiced by Chelsea Peretti) - A goldfish that is owned by Splinter and was accidentally flushed down the toilet by Leo months ago. After traversing through the sewers and nearly being eaten by Trash Wizard, Piebald swallowed an Oozesquito and mutated into her current form with camouflage abilities. She secretly returned to the lair and masterminds a scheme with Splinter to teach the Turtles a lesson about the dangers of lying through picking them, Splinter, and Frankenfoot off one by one.

• Gentry (voiced by Evanna Lynch) - A young Yōkai witch from the Hidden City's Witch Town district who befriends April and (though much less) Donatello.

• Hamato Atsuko (voiced by Keiko Agena) - Hamato Yoshi's late mother who died in her duty to her family's destiny to contain the Shredder while Yoshi was still a child. She was Karai's descendant.

Villains[edit]

• Foot Clan – A ninja clan seeking to resurrect the Shredder and take over New York City. They can make origami ninjas out of paper and have the power of teleportation through hidden gateways. In "Shadow of Evil", it is revealed that the Foot uses a shoe store called the Foot Shack as a front for their activities. Most of its members have been fans of the Lou Jitsu films. In "How to Make Enemies and Bend People to Your Will", Baron Draxum took command over the Foot after exploiting a loophole in the clan's rulings of leadership. However, in "End Game" and "Many Unhappy Returns", it is revealed that the Foot were just manipulating Draxum into donning the Kuroi Yōroi so it could drain his life force to reassemble and resurrect the Shredder.
  • Oroku Saki / Shredder (voiced by Hoon Lee) - The original leader of the Foot Clan. 500 years ago, Oroku Saki was possessed by the demonic Kuroi Yōroi armor that swallowed his soul after having to make a deal with a powerful Oni (Krang), to forge this nigh-unstoppable armor. Shredder terrorized Japan until he was defeated by the Hamato Clan with his armor being broken into pieces and scattered across the world to prevent his return. The Foot and Baron Draxum began seeking out the fragments of the Kuroi Yōroi to reassemble it and resurrect the Shredder, the latter being tricked into wearing the armor so his life force can be siphoned. Shredder reconstitutes himself after the Turtles broke the armor off of Draxum, though only as a feral beast due to something that went wrong with his resurrection. Big Mama provides a mystic collar for the Turtles and Splinter to trap Shredder in another dimension, though she makes a secret last-minute alteration to this plan. This was revealed to have involved placing a control device on the Shredder and using the associated magic ring to control Shredder into being "Shadow Fiend" and abducting Meat Sweats, the Foot Recruit, Hypno-Potamus, Ghostbear, and Carl Sando for her Battle Nexus tournament in New York. When the Foot Recruit claims the magic ring, she controls the Shredder into destroying the Grand Nexus Hotel as she shouts the Foot Clan's name. When the Turtles, April, and Splinter went into the Twilight Realm to get the weapon needed to defeat Shredder, the side effect caused Shredder to regain his intelligence. After he captured Splinter and Baron Draxum, Shredder made the Foot Recruit his general perform a ritual to drain Splinter's essence. With help from the Hamato Clan, the Turtles defeated Shredder by vanquishing the Kuroi Yōroi for good and brought back Oroku Saki to the Hamato Clan.
  • Foot Lieutenant (voiced by Rob Paulsen) – A leading officer of the Foot Clan.
  • Foot Brute (voiced by Maurice LaMarche) – A buff member of the Foot Clan who works alongside Foot Lieutenant.
  • Jocelyn (voiced by Cree Summer) - A Foot Initiate who gains the mark of the Foot in "How to Make Enemies and Bend People to Your Will". Foot Recruit claimed to Baron Draxum that she got the mark because her parents are "big donors".
  • Foot Soldiers (Various Voices) - An army of ninjas that are associated with the Foot Clan.
  • Origami Ninjas – Ninjas made out of paper that is created by Foot Lieutenant and Foot Brute.

• Krang - parasitic aliens who invaded the earth a long time ago but were defeated and banished to another realm, they have also brought Empyrean to the earth, which is the source of Yōkai power, and when the Foot Clan came under attack, they gave Oroku Saki the Dark Armor which eventually consumed his soul and turned him to the Shredder, and Foot clan became their worshipper. Only three of them managed to survive by the time they were freed, one was their leader who was banished again by Leo, the other was a female warrior with a temper who was captured by humans and the third one who's mute was in charge of bringing the Technodrome and controlling it who was apparently destroyed with it.

  • Krang Two (voiced by Toks Olagundoye) - The sadistic and temperamental member of the Krang.
  • Krang Three - The silent member of the Krang.

• Huginn and Muninn (voiced by Timothy Simons and Sam Richardson^[11]) – Two small gargoyles with retractable wings that were often seen sitting on Baron Draxum's shoulders. Huginn has a frog-like body and a cat-like head and tail while Muninn has a frog-like body and a tapir-like head. Their names and presence as Draxum's constant companions are a play on Odin's ravens Huginn and Muninn. In the episode "Goyles, Goyles, Goyles", Huginn and Muninn are shown to be looking for new employment after Draxum went into hiding due to his life force being drained by the Kuroi Yōroi. It is then shown in a flashback that Huginn and Muninn were constantly mistreated by their fellow gargoyles before being hired by Draxum. It is also revealed that it was actually their fault Hamato Yoshi escaped and destroyed Draxum's laboratory, killing all of Draxum's other test subjects. The duo is not seen again for the rest of the series.

• Garm and Freki (voiced by Fred Tatasciore) – Two guardsman warriors that worked for Baron Draxum who are experts at armed combat. They can also ride giant demon-like dogs. In "Repairin' the Baron", Garm and Freki are offered forgiveness from the Council of Heads if they bring Draxum to the Hidden City to stand trial for his crimes. They are later mentioned by Draxum to Raph and Mikey to be bounty hunters that work for whoever has the most money. Their names are a play on the wolf monster Garmr and Odin's wolf Freki.

• Oozesquitos – A swarm of mutant mosquitoes that are often used by Baron Draxum.^[12] They store mutagen in their abdomens to inject anyone they bite which turn them into mutants. The Oozesquitos are first seen when Draxum tests the mutagen on a delivery guy named Stewart. In the Turtles' first encounter with Draxum, they accidentally unleash the Oozesquitos into New York City. The episode "Bug Buster" reveals that Big Mama uses the Oozesquitos so that they can fight for her entertainment in the Battle Nexus much to the annoyance of Draxum. He also had a hand in the Ninja Turtles' origins. As Draxum called them his "bugs", Huginn and Muninn stated that the Turtles called them Oozesquitos, which is catchy to them.

• Mutant Silverfish – A bunch of mutant silverfish. If they are attacked, the Mutant Silverfish will split into smaller silverfish that would later aggregate back to their original state.

• Rupert Swaggart / Meat Sweats (voiced by Johnny Rotten^[11]) – Rupert Swaggart former celebrity chef who was turned into a mutant domestic pig upon being stung by an Oozesquito while hitting a failing contestant with a slab of pig meat during his TV show "Kondescending Kitchen".

Meat Sweats habitually makes any mutant he catches into his "meals" to strengthen the "flavor".^[13]

• Albearto (voiced by Tom Kenny impersonating Ed Wynn^[11]) – An animatronic brown bear used at children's birthday parties in Albearto's Pizzeria.^[14] After a small child short-circuited him, April had Donatello upgrade him where a stage mishap caused Albearto to get electrocuted and come to life. In "Al Be Back", Albearto returns where his head was salvaged by Baxter Stockboy in exchange for the cheat codes for the dance game. While on a car, he places his head on a new Albearto body in front of the birthday kids, gets the manager's handprint for the security scanner, and animates his bear "brothers" from failed franchises to attack Albearto Land where Albearto also animated the Albearto animatronics there. The Ninja Turtles put on a concert that Albearto and his animatronic "brothers" attend which causes most of them to destroy themselves after the Ninja Turtles' singing drives them mad. Albearto is the only one to escape, but his final fate is left unclear.
  • Al-Beardo the Pirate (voiced by Tom Kenny) - An animatronic bear pirate with a hook for a right hand, an eyepatch over his right eye, and a left peg leg who is the mascot of a failed Albearto's British- and pirate-themed franchise called "Al-Beardo's Squid and Chips".

• Warren Stone (voiced by John Michael Higgins^[11]) – A semi-successful and narcissistic news anchor who mutated into a small mutant earthworm with an earthworm tail instead of legs after being stung by an Oozesquito.^[14] If cut in half, Warren can regenerate. Since his mutation, he self-declared himself the greatest foe of the Teenage Mutant Ninja Turtles always ignore him. Warren Stone later gains a gauntlet that can shoot beams which he named Charlotte. This was later found to be one piece of the Kuroi Yoroi that was needed to revive Shredder. In "Warren & Hypno, Sitting in a Tree", Warren has become a roommate of Hypno-Potamus and also loses the gauntlet to Baron Draxum so that the Foot Clan can use it in their plot to revive Shredder, though April does remember who Warren is since she was part of the Stoneheads. While heavily implied in the show but not outright confirmed, social media posts from writer Russ Carney and executive producer Andy Suriano have confirmed that he and Hypno-Potamus are a couple. ^[15][16]

• Mezmer-Ron / Hypno-Potamus (voiced by Rhys Darby^[11]) – Mezmer-Ron successful stage magician and hypnotist who mutated into a hippopotamus after he was stung by an Oozesquito that merged him with his pet hippopotamus Doug.^[14] Driven by envy, Hypno-Potamus strives to outachieve any magician with an even greater "trick" than they can produce, and find a way to bring Doug back to life, leading to his clashes with the Teenage Mutant Ninja Turtles. In "Warren & Hypno, Sitting in a Tree", Hypno-Potatmus has become a roommate of Warren Stone, later being captured by Baron Draxum in an attempt to lure Warren and the turtles to him so Draxum could capture them and take Warren's gauntlet - a plan that Hypno took part in in order to secure Warren's safety. However, once it was revealed that Draxum had no real intent to keep Warren safe, Hypno temporarily sided with the turtles - resulting him saving Warren's life and the two leaving peacefully. While heavily implied in the show but not outright confirmed, social media posts from writer Russ Carney and executive producer Andy Suriano have confirmed that he and Warren Stone are a couple. ^{[15] [16]}

She is the owner of an extradimensional gladiator arena called the Battle Nexus which is hidden in the secret sub-level of The Grand Nexus Hotel that is owned by her human form. Big Mama uses the Oozesquitos in her possession to mutate anyone into mutants so that they can fight for her entertainment in the Battle Nexus. Her plot has brought her into conflict with Baron Draxum who felt that Big Mama was misusing the Oozesquitos. Hinted in "The Ancient Art of Ninja Hide and Seek", the episode "Many Unhappy Returns" reveals that Big Mama was the ex-girlfriend of Hamato Yoshi and the indirect cause of his mutation when she abducted him to fight in the Battle Nexus. In "Battle Nexus: New York", Big Mama transported the population of New York to a cruise inside a mystical sphere so that she can have the Turtles and their mutant enemies fight her Battle Nexus Champions. Once the Battle Nexus Champions are defeated, the Turtles go to the Grand Nexus Hotel to confront Big Mama and her latest champion Shadow Fiend. The Foot Recruit found that Shadow Fiend is actually Shredder who is being controlled by a control device on him by Big Mama using the device's associated magic ring. Once the Foot Recruit claimed the magic ring and gains control of the Shredder, she tells a cowering Big Mama that she is about to lose everything as she advises her to start running.
