Upon learning of Yoshi's survival, and later his mutation into Splinter, Shredder vowed a vendetta against him and the turtles. This led to his dealings with the Kraang and ultimately placing his want to kill Splinter over his own survival. He does succeed in killing Splinter during the Triceraton Invasion but the Turtles travel back in time to save Earth and warn Splinter, foiling Shredder's attempt and resulting in him being mortally wounded and subjecting himself to a refined mutagen to heal his wounds while gaining new power. This results in him becoming Super-Shredder who is larger with retractable claws and blades coming out of his back, arms, shoulders, parts of the legs, knees, and feet. He eventually succeeds in finally killing Splinter a second time by running him through with his mutated arm-blades, and is ultimately destroyed by Leonardo's katanas.
• Chris Bradford/Dogpound/Rahzar(voiced by Clancy Brown) - Chris Bradford was a world-famous martial artist who is secretly a prized member of the Foot Clan, armed with a 400-year-old katana and owning a chain of dojos across the country for the purpose of recruiting Foot Soldiers. He mutated into the mutant Akita called Dogpound as a result of being bitten by Shredder's pet Akita Hachinko, hampering most his fighting abilities as he attempted to find a means to restore his humanity. But being knocked into a mutagen vat caused Bradford to be mutated further into a near-skeletal werewolf-like form and is referred to as Rahzar since.
• Xever Montes/Fishface (voiced by Christian Lanz) - Xever Montes was a Brazilian street urchin who was left to roam the criminal underworld of São Paulo, eventually being recruited by the Shredder after attempting to steal something belonging to him.

Following the mutation, he wears a water-breathing rig and mechanical legs developed by Baxter Stockman.
• Baxter Stockman / Stockman-Fly - (voiced by Phil LaMarr) - Baxter Stockman was a child prodigy who tried proving his brilliance at a science fair at school by presenting a volcano with real lava, which ended up burning down the gym and getting him expelled. Baxter was eventually brought into Shredder's services and reversed-engineered much of the Kraangs' technology before he briefly escaped. After being recaptured, Stockman was outfitted with a mutagen collar to hinder any further treachery. But after failing a few more times, the collar is triggered and Stockman is mutated into a mutant housefly while later placed in charge of mutagen experiments. While Shredder was bedridden in the aftermath of the Triceraton invasion, Stockman oversees Shredder's mutagen intake and created two bug-mutants to assist him in an attempt to replenish the Foot's wealth. He is finally restored to his original human form by Donatello's retro-mutagen.

He later lost his eye following his first engagement with the Turtles and ended up in the 1987 cartoon series dimension, but eventually returned and became Shredder's second-in-command.
• Ivan Steranko/Rocksteady (voiced by Fred Tatasciore) - Ivan Steranko was a Russian arms dealer and artifact collector with a gold tooth and a diamond right eye, who is an old friend and business partner of Shredder. However, a falling out resulted in Steranko being mutated into a mutant white rhinoceros called Rocksteady upon being pushed into a mutagen vat filled with white rhinoceros DNA.
• Anton Zeck/Bebop (voiced by J.B. Smoove) - Anton Zeck was a professional thief in a high-tech suit with a purple X-ray visor and armed with high-tech gadgets. Hired by Steranko to steal the Kuro Kabuto, Zeck was later mutated into a mutant common warthog called Bebop upon being shoved into a mutagen vat filled with common warthog DNA.
• Shredder Mutants - A trio of mutant clones created by Stockman-Fly from the DNA of the Shredder and different crustaceans. They serve as the guards of the Foot Clan's lab. While Mikey fights Stockman-Fly, the others fight the Shredder Mutants. Once Splinter manages to regain his mind, he defeats the Shredder Mutants by kicking them into the giant fan below. In "Meet Mondo Gecko," silhouettes of a second set of Shredder Mutants are seen among the audience during the race.

Kraang

The Kraang are a race of brain-shaped aliens from Dimension X, piloting robotic bodies called Kraangdroids that are responsible for bringing some mutagen to Earth a thousand years ago. As revealed in "The War for Dimension X", the Kraang are actually Utroms that are now psychically controlled by Kraang Prime resulting in the Kraang Hive Mind. As they became extensions of Kraang Prime's will with trace remnants of individuality, they have not mastered English and communicate in redundant speech. The Kraang also have enemies in the form of the Triceraton Empire and the Utroms who Kraang Prime could not place under mind control. Among the known Kraang are:

  • Traag - A 20 ft. lava-spewing rock monster from Dimension X with regenerating abilities who is in service to the Kraang. He first appeared in "TCRI," where he was brought by the Kraang through a portal that connected TCRI to Dimension X. He proved to be a challenge to the Turtles, so Leatherhead ended up dragging him through the portal back to Dimension X. In "Showdown," Traag was seen guarding the portal when the Kraang upgraded it with a force field. When the Turtles tried to destroy it, they drew the attention of him and the Kraang, so Leonardo used the laser to disintegrate Traag. In "Into Dimension X," Traag teamed up with Granitor to attack the Turtles near the Kraang's facility in Dimension X. However, they were both defeated by Michelangelo in his "savage" suit when he used his voice to break apart the part of the cliff both rock monsters were on.
  • Granitor - A 20 ft. blue fire-spewing rock monster from Dimension X with regenerating abilities who resembles Traag (but is pale pink in color) and is in service to the Kraang. He first appeared in "Into Dimension X," where he teamed up with Traag to attack the Turtles near the Kraang's facility in Dimension X. However, they were both defeated by Michelangelo in his "savage" suit when he used his voice to break apart the part of the cliff both rock monsters were on.

Alien species

Main article: List of Teenage Mutant Ninja Turtles alien races

In addition to the Kraang, there are many other alien species throughout the show:

Aeons

The Aeons are an ancient alien race of benevolent, ethereal beings that hail from the planet called Zalvadal; a world of vast, beautiful gardens and tranquility that contains all of the sacred knowledge in the cosmos. They were the very first extraterrestrials to evolve into higher beings of mighty power. The very source of all their strength is a mighty crystallized artifact called the Sol Star, containing the very essence of power and life itself. Once hidden away, the entire world turned pure evil and corrupted the Aeons as well. When April had restored the world to its former state and splendor, by placing the mystical Sol Star on its rightful place, the grateful Aeons gladly gave her a small fragment of it, assuring her that it would grant her luck and great power. However, they may not have been aware of how the Sol Star fragment was gradually corrupting April to the point of insanity. Among the known Aeons are:

• Za-Naron (voiced by Mae Whitman) - A supremely powerful and dangerous Aeon that seems to dwell within the mystical Sol Star fragment that is worn by April. After all of April's psionic abilities are immeasurably magnified to uncontrollable levels, it suddenly awakens Za-Naron and she takes possession of April, planning to use her powers to save Earth by destroying humanity.

Daagon

The Daagon are a race of aquatic amphibian aliens that reside in the cosmic ocean of Varuna, a liquid nebula over which they rule. They are one of the few aliens that served as the guardians of the Heart of Darkness fragments. Among the known Daagon are:

• Hiidrala (voiced by Lucy Lawless) - The queen of the Daagon with tentacled arms and hair. She is the only one to have complete power over the Cthugga.
• Daagon Soldiers - The foot soldiers of the Daagon Empire. Michelangelo nicknamed them "Merdudes."

Neutrinos

In this show, the Neutrinos are a race of microscopic aliens.

• Neutrino Mercenaries (voiced by Clancy Brown) - A trio of Neutrinos who were sent by Bellybomb to infiltrate Mikey's mind for plans for the black hole generator to give to Lord Dregg, but were defeated by the other Turtles after they were sent into Mikey's mind. After returning to the real world they tried to escape but Mikey grabbed them and squished them with his foot.

Salamandrians

The Salamandrians are a race of humanoid aliens that resemble newts and salamanders. The known Salamandarians are:

• Newtralizer (voiced by Danny Trejo) - A fire-belly newt-type Salamandrian in a weapon-upgraded suit of high-tech armor with a huge mouth used to eat the Kraang where he was considered dangerous to them.

Triceraton Empire

The Triceraton Empire is an empire that is inhabited by Triceratons, a race of Triceratops-like aliens. Triceratons breathe nitrogen and the oxygen in Earth's atmosphere can lead to delusions. The Triceraton Empire has been at war with the Kraang for some time, a conflict that has resulted in the destruction of the Triceraton homeworld through the Heart of Darkness (a black hole generator) and thus left the Triceratons obsessed with annihilating their enemies by any means necessary such as destroying any planet that the Kraang want to take over. In the first half of the fourth season, they replace the Kraang and the Foot Clan as one of the main villains in the series. With the exception of Captain Mozar, all the Triceratons introduced so far have names that start with Z. Among the known Triceratons are:

• Emperor Zanmoran (voiced by Michael Ironside) - The ruler of the Triceraton Empire, a 250-centimeter (8.2 ft) Triceraton with a more ornate uniform including a cape. Zanmoran is a sadistic ruler, having decreed Earth's destruction due to its Kraang infestation. After the Turtles travel back in time to prevent this, they are captured during their infiltration of the Triceraton Mother Ship, and their efforts impress Zanmoran enough that he orders them to be thrown into the arena. When the Fugitoid is captured during an effort to rescue them, Zanmoran attempts to force him to repair the Black Hole Generator, but he refuses. The Turtles subsequently escape by briefly taking Zanmoran hostage.
• Mozar (voiced by Michael Dorn) - The Supreme Commander of the Triceraton fleet with a broken horn and a prosthetic beak, initially introduced as a captain. He is a 250-centimeter (8.2 ft) Triceraton who is a cunning and brutal military commander. He answers only to the Triceraton Emperor and aims to destroy the enemy at any cost. He debuts in "Annihilation: Earth" Pt. 1 where he leads the Triceraton invasion on Earth to destroy it and thus prevent the Kraang from using it as a new homeworld, and employs the Heart of Darkness previously used by the Kraang to destroy the Triceraton homeworld. However, the Turtles escape Earth's destruction and then travel back in time six months in an effort to prevent this event from happening. They would eventually cross paths with Mozar during their quest where he was promoted to Admiral for successfully retrieving the first piece of the Heart of Darkness. It is later stolen back by the Turtles during their raid on Emperor Zanmoran's ship. Mozar was later demoted back to Captain by the time he attacked the Ulixes in order to reclaim the Heart of Darkness fragment. Despite the fact that the Skeevix Virus launched at the Ulixes was defeated, his soldiers were successful at reclaiming the two fragments of the Heart of Darkness.
• Sergeant Zog (voiced by Lance Henriksen) - A 260-centimeter (8.5 ft) Triceraton who serves as a scout for the Triceraton army. He debuts in "Dinosaur Seen in the Sewers!" where he temporarily befriends Raphael. Due to being poisoned by Earth's atmosphere, he is initially delusional, striking at virtually any being he comes across and rambling on about his mission. After recovering his equipment at the Statue of Liberty, he recognizes Raphael's deception and attacks him before launching a beacon to summon the Triceraton armada to Earth. Left clutching onto a ledge on the Statue of Liberty, Zog refuses Raphael's offer of help and drops from the torch, apparently to his death declaring "Long Live the Triceraton Empire."
• Commander Zoran (voiced by Kevin Michael Richardson) - A commander in the Triceraton army.
• Commander Zorin - The second-in-command of the Triceratons who assisted Mozar in the attack on Earth.
• Sergeant Zark - A sergeant of the Triceraton army who assisted Mozar in the attack on Earth.
• General Zera (voiced by Kate Mulgrew) - A female Triceraton that was introduced in the TV film "Half-Shell Heroes: Blast to the Past". She is in command of a Triceraton operation in the Cretaceous period seeking to obtain the rare mineral Chronite and use its time traveling properties to conquer and plunder various time periods. Despite commanding a Triceraton garrison, a force of Robot-Raptors, and a Robo-Spinosaurus, she was defeated by the Turtles and their dinosaur allies. Zera is the first known case of a Triceraton female in the series, as all other Triceratons who have appeared onscreen have shared the stereotypical male design.
  • Lieutenant Zorg (voiced by Fred Tatasciore) - An overweight Triceraton who serves under General Zera.
• Lieutenant Zovox (voiced by Michael Dorn) - A Triceraton that accompanied Captain Mozar to the planet Xaava-Dal.
• Zarus (voiced by Kevin Michael Richardson) - A Triceraton scientist who accompanied Captain Mozar to the planet Xaava-Dal.
• Zeno (voiced by John DiMaggio) - A 491-centimeter (16.11 ft) Triceraton warrior who was condemned to the Tri-Arena for not wanting to help Emperor Zanmoran search for the fragments of the Heart of Darkness. Since his imprisonment, he has become a star gladiator; he is thus reminiscent of the 2003 series character Traximus. Zeno fought the Turtles in the arena after giving them advice about their first match, but was later convinced to help them escape due to their shared contempt for the Heart of Darkness/Black Hole Generator.
• Lieutenant Zax (voiced by Clancy Brown) - A Triceraton who assisted Captain Mozar into reclaiming the two fragments of the Heart of Darkness from the Turtles and later obtaining the final fragment of the Heart of Darkness from the planet Magdomar.
• Triceraton Soldiers (Various Voices) - The foot soldiers of the Triceraton Empire.

Utroms

The Utroms are the peaceful counterparts of the Kraang who resisted Kraang Prime's mind control. The Utroms are ruled by the Utrom High Council who are named after chess pieces. Among the known Utroms are:

• Queen (voiced by Cassandra Peterson) - An Utrom who is a member of the Utrom High Council. She pilots a recolored version of Mrs. Campbell and wears a tiara in her base Utrom form.
• Bishop (voiced by Nolan North) - An Utrom that pilots a Kraangdroid in sunglasses and is the original designer of the Kraangdroid body. He is Kraang Subprime's brother and broke the Utrom vow of non-involvement in Earth affairs by contacting the Turtles to warn them of the Technodrome's rise from the sea and of the imminent arrival of the Triceraton armada. Bishop also took part in efforts to bring down the Technodrome before the Triceratons arrived, and then to stop the Heart of Darkness from activating, but was thwarted in both attempts. The Turtles later met Bishop again-though from his perspective it was for the first time-when they traveled into the past to try and prevent Earth's destruction. He is revealed to be an old friend of Professor Honeycutt's, but was unaware of the Professor's brain being installed into a robotic body. He and the rest of the Council meet to discuss the Turtles' request for their help, only to be attacked by Kraang Sub-Prime and his forces. Later Bishop and his peers lead an Utrom attack on Kraang Sub-Prime's base, during which Bishop engages his former brother-previously known by the name Knight-and defeats him. After Kraang Sub-Prime's apparent destruction, Bishop then reveals to the Turtles the locations of the last remaining components of the Black Hole Generator. He later returned to help the Turtles save the world from the fiery wrath of Tokka, and is now in charge of TCRI.
• Rook (voiced by Kate Micucci) - An Utrom who is a member of the Utrom High Council. She pilots a recolored version of Irma Langinstein, revealed to be the creator of the droid model with a grudge against Kraang Subprime for stealing her design.
• Pawn (voiced by Nolan North) - An Utrom who is a member of the Utrom High Council and speaks with a French accent. He pilots an Utrom-colored Kraangdroid identical to those used by most of the Utrom, with the addition of a curly mustache.

• Varuna Sea Monster - An unnamed alien sea creature resembling the Loch Ness Monster that comes from the cosmic ocean of Varuna.

Besides breathing fire, Tokka can also fly even into space.
