This is a list of alien races from Teenage Mutant Ninja Turtles.


The Antarians hate violence and appear in the "Invasion of the Turtle Snatchers" episode of the 1987 cartoon, when a family from a planet orbiting Antares travels to the Earth.[1] The family members are named Klaatu, Barada, & Nikto (a nod to the famous phrase from The Day the Earth Stood Still.[2]

The Kraang[edit]

Main article: Krang

The Kraang are a species of aliens that appear in the 2012 TV series, which are an homage to both Krang and the Utroms. Like the untroms, they can have human disguises, however, they are all identical. They are the main antagonists of the series. The Kraang's voices are provided by Nolan North, with at least one female Kraangdriod voiced by Cassandra Peterson. Their leader Kraang Prime is voiced by Roseanne Barr.[3] Not unlike the Utroms in the Mirage comics and 2003 TV Series, their history is intertwined with the Turtles. It was they who attacked Splinter while he was holding the not-yet-mutated Turtles, causing them to fall into the ooze. When the mutated turtles went to the surface world 15 years later, they find the Kraang about to kidnap April O'Neil and her father. After a failed attempt due to a lack of chemistry, the turtles invade the Kraang base and rescue April, but fail to save her father. After several other encounters, the Turtles find the Kraang abusing Leatherhead and save him. Later, Leatherhead tells them that the power cell he was protecting powers the portal to their dimension. The Turtles escape with the power cell in an empty subway car. Donatello modifies this into the Shellraiser, their mode of transportation, but they procure the power cell when Donnie saved an unskilled wanna-be hero named the Pulverizer instead of getting the cell.

The turtles find the Kraang's lair in the TCRI building, and use Leatherhead to get in. They are knocked out by poisonous gas and faced with an invincible rock monster called Traag. Luckily, Leatherhead comes in and is able to overpower Traag, but can't destroy him. Leatherhead then drags him through the portal to save the turtles from his evil. Since then, the Kraang have tried several dangerous invasion plots, but have been foiled by the turtles.


The Neutrinos appear in the 1987 cartoon, Archie Comics, IDW comics and the video game Teenage Mutant Ninja Turtles: Tournament Fighters, and are peace-loving teenagers from Dimension X, who travel by flying craft looking a lot like 1950's and 60's American automobiles.


Polarisoids appear in the "Camera Bugged" and "Welcome Back, Polarisoids" episodes of the 1987 cartoon, when a family from a planet orbiting Polaris travels to the Earth. Their camera is able to shrink people and objects and teleport them inside the camera.[4] The family members's names are Frip, Millimeter, F-Stop & Say Cheese[5]

Rock Soldiers[edit]

Sons of Silence[edit]

Sons of Silence is a group of aliens in the Archie Comics.[6]

Stump & Sling[edit]

Stump & Sling are two tree-like wrestling promoters on the Stump's Asteroid.[7]


Triceratons refers to the alien race, resembling anthropomorphic Triceratops dinosaurs.

They are recurring characters in the Mirage comics

The Triceratons appear in only one episode of the 1987 animated series, "Night of the Dark Turtle", and are not seen again.

They also appear in various video games.

The Triceratons were featured in the 2003 animated series as a race that desires galactic conquest. They have advanced technology, a strong government, and gladiatorial battles. Due to the Triceratons' hostility towards humans, Earth attempts a nuclear attack on their planet. There are many notable Triceraton figures in the series.

An individual Triceraton is briefly seen in Tiger Claw's flashback in the episode "The Wrath of the Tiger Claw" of the 2012 series.

Commander Mozar[edit]

Commander Mozar is the military commander of the Triceraton Republic in the Mirage comics and 2003 series. Mozar is the counterpart of General Blanque when it comes to military matters. Mozar is the dedicated right hand of Zanramon, the Triceraton Prime Leader. He led the mission into territory controlled by the Federation of D'Hoonib, seeking to capture Professor Honeycutt. He succeeded, thanks to help from Blanque's private aid. However, he also captured the Turtles in the bargain.

In the third season of the 2003 series, during the massive Triceraton invasion of Earth, Mozar begins to resent Zanramon's tyranny and bloodlust, and is visibily disturbed when he is ordered to leave the majority of their troops to fend for themselves in order to save the homeworld from Honeycutt's virus. When the rebel leader Traximus arrives to depose Zanramon, Mozar holds no objection and gladly orders his troops to stand down as his leader is overthrown. He remains a right hand to Traximus after Zanramon's fall from power.


Traximus was a noble warrior of the Triceraton Republic who believed that its old virtues should be restored in the 2003 series and the video game Teenage Mutant Ninja Turtles 2: Battle Nexus. He spoke to the council and, at the orders of the tyrannical Zanramon, found himself in the dungeons with warriors taking part in "The Games". He was left to rot in his despair until he was bested by Leonardo, who spared his life with honor. Inspired by this act of kindness, Traximus regains hope that the current dictatorship can be overthrown, and leads the other gladiators to freedom in the midst of the chaos surrounding the Turtles' escape. He participates in the Battle Nexus tournament, though only to court more warriors to aid him in his cause. He is eliminated from the tournament by Raphael, but the two work together to free the imprisoned Splinter from the Daimyo's son, and Traximus is ultimately the one who saved the protagonists from falling into a rift in time and space when he anchors his axe into the ground and holds onto them all. In the third season, as the Triceratons invade Earth, Traximus has recruited a larger following after the Battle Nexus, and he aids the Turtles in rescuing the captured Donatello. At the end of the six-part story arc, Traximus has finally overthrown Zanramon and declares the war with the Federation to be over, expressing his wish for a new age of peace and honor to begin, with no further absolute rulers as Zanramon was.


Zanramon is the Prime Leader Zanramon of the Triceraton Republic led the war against the Federation of D'Hoonib in the Mirage comic book and in the second Ninja Turtles animated series. Zanramon first appears in TMNT (vol. 1) #6, where he captures the turtles and Professor Honeycutt, wishing to acquire Fugitoid's teleporting technology for the Republic's use. The turtles' captivity is short-lived, however, as they manage not only to free themselves and the Fugitoid but to take Zanramon hostage as well. While making their escape, Zanramon is accidentally shot by his own guards and presumed dead by the turtles. Zanramon is not heard of again until TMNT (vol. 4) #28, where Michelangelo is informed that Zanramon had survived, and was no longer Prime Leader of the Triceratons: after the Fugitoid's escape, the then-leader lost political capital, and he was quickly deposed by opposing factions.

In the 2003 series, when Professor Honeycutt was brought to him, he offers the robot full civil rights and privileges of a Triceraton citizen, but eventually resorts to forcing Honeycutt to build his teleporter lest he execute the Turtles. However, the Turtles survive both the Triceraton prison and the gladitorial arena, and take the prime leader hostage, culminating in the theft of his personal space cruiser. When Honeycutt is traced to Earth months later, Zanramon orders a full strike on the planet. Humanity ultimately loses the battle with the Triceratons, when even the Justice Force and nuclear weapons can turn the tide, and Zanramon demands they turn over the Professor or the Earth is destroyed - also revealing Donatello to the entire world (though this thankfully has no lasting effects on the Turtles' secrecy). The Turtles return, rescue Donatello, and once again steal Zanramon's cruiser, to his rage. When Donatello is able to convince him that the Professor is not on Earth, Zanramon orders a retreat, only to deploy his forces yet again when the Professor finally appears on Earth. To Commander Mozar's disgust, Zanramon exhibits increasing amounts of ruthlessness, even to the point of abandoning the majority of his armed forces. Zanramon is immediately dethroned by Traximus, and is forced to occupy a cell facing his nemesis, former Federation leader Blanque.


In the Mirage comics, Zog was one of two Triceraton soldiers left on Earth when the Utroms left. Some time later, Raphael found him in the sewers, and the Turtles used him to aid in their attack on the Foot. His mind was almost nothing, often laughing and priding himself on "knowing all." He mistook the Turtles for leaders of a Triceraton invasion and referred to Raphael as commander Zoraph. Having sustained substantial damage by a number of Foot ninja, he was eventually killed by the three mutated Shredder clones when he charged too far ahead of the team.

In the 2003 series, Zog was one of the Triceratons teleported to Earth mid-battle with the Federation over Honeycutt's teleporter. However, while the other Federation and Triceraton forces are returned home by the Utroms, Zog became lost in the sewers, and was found by the Turtles choking to death from lack of his native air. Believing the Turtles to be Triceraton-allied military leaders, Zog pledges his undying loyalty to them and later "General" Splinter, in particular befriending Michelangelo. Zog participates in the Turtles' assault on the Shredder's feighter ship, and was a valuable asset thanks to his size and ferocity. Zog personally battles the Shredder and proves to be quite a match for the Utrom. In a heroic sacrifice, Zog grabbed hold of the Shredder and tossed them both into the flames of the sinking ship, in an attempted murder-suicide, wishing for his story of loyalty and honor to be told by his commanding officers. Tragically, the Shredder survives this attack, but the Turtles recognize that Zog gave them their lives with his sacrifice.

When the Turtles travel back in time to the Cretaceous era, they encounter a Triceratops who befriends Michelangelo, who wonders if he is an ancestor of Zog, though Donatello quickly reminds him of Zog's nature as an alien. Nevertheless, Michelangelo dubs the Triceratops Zog in his friend's memory, and the dinosaur proves to be an invaluable ally during the Turtles' stay in the Cretaceous. In the final 'Back to the Sewers' season, Michelangelo encounters a ceratopsian with the horns of a Triceratops and the frill of a Styracosaurus, who he dubs Zog II, proving that the Turtles, despite the four season amount of time that had passed, had not forgotten the sacrifice of their friend.

Captain Zarax[edit]

Captain Zarax appears in the 1980s animated series.

Voiced by Dorian Harewood.


The Utroms are aliens in the Teenage Mutant Ninja Turtles universe that resemble the brain.


Main article: Krang

Krang is suggested to be an Utrom in the daily comic strip.

An Utrom named Krang (who has no resemblance to the original) makes a small appearance in the 2003 series.

General Krang is considered an Utrom in the IDW Comics. He is one of the major antagonists in the series and is more cunning and threatening than the 1987 version.


Korobon is an Utrom who declared himself ambassador to Earth from the Utrom Confederation. He addressed the U.N. on live television and explained what the Utroms had planned to do on Earth. He appeared in Volume 4 of the Mirage comic.

Mr. Mortu[edit]

The name is actually "Utrom" spelled backwards, Mr. Mortu is an Utrom commander (voiced by Dan Green) and one of the Utroms stranded on Earth when the Utrom criminal Ch'rell forced the prison ship transporting him to crash in feudal Japan in the 2003 series. He remains on Earth though the centuries, later stationed at the Utrom's Tokyo headquarters following World War II. He is saved from muggers by a young Hamato Yoshi and Yukio Mashimi, who discover his secret during the scuffle. He inducts both into the ranks of the Guardians, and is forced to evacuate the Tokyo facility after Mashimi betrays them to the Shredder.

In the present day, he is stationed in New York City in the TCRI building, the Utroms' New York base of operations. When Splinter is injured in the Turtles' assault on the Shredder's headquarters, Mortu has him brought to the TCRI building and cared for, unbeknownst to the Turtles. When the Turtles return to Earth from their voyage across space, it is Mortu who transmatted them home and who brings the healed Splinter to them. He shows the Turtles and Splinter the origins of the Utroms on Earth using a communal mind pod, but the experience goes terribly wrong when Baxter Stockman hacks the system and traps the Turtles and Splinter in the simulation. As the Shredder (by then revealed to be the alias of the criminal Ch'rell) and his forces destroy the building, Mortu and the Utroms transmat back to their homeworld. Before they leave, Mortu presents Splinter with gift: an orb containing memories of his master Yoshi from the Guardian archives.

When the Turtles later destroy the Shredder's starship with themselves aboard in an effort to keep him from plundering the galaxy, Mortu's forces arrive seconds before the detonation, encasing the Shredder's ship in a stasis bubble long enough to transmat the Turtles and Splinter to safety, and the Shredder and his accomplices to holding cells. Mortu later presides over the tribunal meeting that sentences the Utrom Ch'rell to exile aboard an icy asteroid.

Mortu attended the O'Neil-Jones wedding as an honored guest. He mentions a bad experience at a previous wedding that seems to have involved being mistaken for an entree at a sushi buffet, which he remains bitter about.

Professor Obligado[edit]

Professor Obligado was a brilliant Utrom scientist. His life and death are shown in the back pages of several issues of the current Tales of the TMNT. "Obligado" means "obligated/forced to" in Spanish, although his name more likely comes from the brain component "medulla oblongata".


Slashuur is a character that appears in the video game "Teenage Mutant Ninja Turtles 2: Battle Nexus". According to it, Slashuur is an Utrom who was slashed when Shredder attacked his own home planet. He survived, but not without two scars. He is a former competitor of the Battle Nexus. For unknown purposes, he became known as the greatest mercenary in the multiverse, which was after he somehow achieved his Slashuur exosuit, with the cost of his own memory. He worked under Shredder, not knowing he was attacked by him. His weapon is a sickle called Gengetsu, which drains people's energy upon impact, feeding it to Slashuur. He has three known costumes. They have the same design, just different colors. The first one is orange, which appears when Slashuur appears in Episode 4-5. The second one is black, which appears when Slashuur appears in Episode 10-3. The third one is when he is a playable character. It is white. After fighting the Turtles twice, he learns what really happens. Slashuur then assists them in their battle in Episode 11, but only in the cutscenes. He doesn't appear in the 2003 series, similar to Planet Zero's appearance in that same game. He is voiced by Jason Griffith.

Dr. Xeinos[edit]

Based on a storyline by Leatherhead creator Ryan Brown, Dr. Xeinos is an Utrom scientist who was caught in the blast of the TCRI building in the Image and Mirage comics. Left behind and abandoned on Earth after the Utroms fled for their homeplanet, he was found by and befriended Leatherhead who nursed him back to health. He also played chess with Splinter. He was revealed to be the one who found Leatherhead in the sewers when he was still a normal alligator.

Ch'rell the Utrom Shredder[edit]


A Zipp is in the 1987 show a little creature from Dimension X, appearing during season 4 ("The Big Zipp Attack"), and increases itself when eating. It also eats metal, and reduction requires them eating Rigidium, a very rare metal on the Earth.[8]
