What do you think I am, I'm Krang! Indisputable ruler of Dimension X!
~ Krang

Krang is one of the two main antagonists (alongside the Shredder) of the 1987 Teenage Mutant Ninja Turtles cartoon series. He is also the central antagonist of the episode "Trans-Dimensional Turtles" in Season 4 and one of the two main antagonists (alongside the Shredder) of the Wanted: Bebop and Rocksteady arc in Season 5 of the 2012 TMNT series.

He is an alien warlord from Dimension X who seeks to both conquer Earth and his home Dimension. He is also the partner of Shredder, whom he often argues and fights with. Truly he is from the dimension of the 2012 show where he was banished by his cousin, Kraang Subprime for his stupidity and because of his insane methods of conquering realms.

He was voiced by Pat Fraley in the 1987 series and the crossovers with the 2012 Teenage Mutant Ninja Turtles series, and Bradford Cameron in Turtles Forever.


1987 series


Before the series started, Krang was once a feared, powerful warlord from Dimension X, a place of continuous war. He controlled an army of Rock Soldiers, under the leadership of his right hand man, General Tragg. One day he was captured and was stripped of his body reducing him to a living brain. Krang (or what was left of him) was then banished from Dimension X, along with his mobile fortress, the Technodrome, to Earth, in hopes he would never return. However, during his stay on Earth, General Tragg continued the war against Dimension X natives, The Neutrinos.

Sometime before the Turtles and Splinter were mutated, Krang met the leader of the Foot Clan, Oroku Saki aka The Shredder, the two began an uneasy alliance. Krang allowed Shredder to access his advance technology in exchange for a new body, in which Krang himself designed. Despite this, Shredder did not live up to this deal as he was afraid that Krang would try to overthrow him. It wasn't until Shredder's countless failed attempts to kill Splinter and the Ninja Turtles that new had to create Krang's new body. When Krang's body was complete, he almost was successful in killing the Turtles and bringing his troops to Earth, but the Turtles foiled his plans and sent Krang, Shredder, and the Technodrome back to Dimension X, and from that point forward, Shredder had no choice but to follow Krang's orders.

Turtles Forever

Krang was one of the main antagonists in the crossover special Turtles Forever, appearing with much of the cast of the 1987 show, crossing over with the 2003 Ninja Turtle series. He is portrayed as ineffectual and easily defeated, though the 2003 Shredder makes use of his Technodrome to try to destroy the Ninja Turtle multiverse. Krang uses his enlargement powers to try to fight 2003 Shredder and save the multiverse, but is quickly defeated.

2012 series

In the episode "Trans-Dimensional Turtles" of the 2012 Nickelodeon Teenage Mutant Ninja Turtles series, he is the secondary antagonist (Shredder does not appear because his voice actor, James Avery, died several years prior). In the special crossover, the 80s turtles summoned the modern turtles to their dimension to help them stop Krang, who had planted a bomb in the city.

After a brief fight in the 80s dimension, all the turtles and Krang go to the modern dimension and Krang plants another dimensionizer bomb on the channel 6 building. The turtles and Krang fight again, this time the 80's turtles use their weapons and Krang temporarily grows to giant size. After he is repeatedly kicked in the face by all the turtles (after he fell over), he escapes to the Technodrome in Dimension X, while the turtles discover that the bombs he's been planting were powerful enough to destroy their entire dimension and that they had a short amount of time to shut them all off.

Unfortunately, Kraang Subprime hacks their dimension transporter and sends them to the Technodrome, much to Krang's displeasure. It is then revealed that Krang is actually Subprime's cousin and that he was banished to the 80's dimension because Subprime thought he was an idiot. After helping Subprime fight the turtles, Krang is then beaten and re-banished by Subprime after the turtles state that the dimensionizers were meant to destroy the dimensions that the Kraang were planning on mutating, angering Subprime beyond belief.


Krang was likely based on the Utroms, who unlike Krang, were a benevolent race of natural brain looking aliens. However, Krang is not an Utrom, in the episode "Invasion of the Krangezoids", Krang cloned himself and while they appear to be brain like creatures at first, the cloning process allowed the cloned Krangs to "re-grow" their bodies as "Some lizards can re-grow their tails" it was here when the first (and only) time we get to see Krang's natural form, which were 10 to 12 foot tall hunched back lizard-like humanoids with Krang's "brain" as their head.

However when Krang was stripped from this form, he appears as large pink brain around the size of a basketball with large eyes and a wide mouth with sharp pointed teeth two long slimy tentacles, and a ridged forehead, to move around he designed a tall, powerful, bulky human-like android with many built in weapons including a chip where Krang and his body can grow to giant proportions, Krang himself would rest in the stomach controlling his body. When his body isn't in use, he uses a much smaller bipedal machine known as a "bubble walker" which is equipped with several weapons.

It is unknown why after Krang was stripped from his natural form, that he never tried to find a way to re-gain it, especially after he found out his clones were able to re-grow their bodies.

Whenever Krang speaks, he sometimes croaks like that of a lizard, possibly due to his reptile heritage.


Krang is known for being a brilliant scientist, having designed countless weapons, including his well known android body. He is a cold, cunning, manipulative and somewhat a sadist, as he claims that he enjoys watching "people and animals suffer" In the Archie Comics he is known to be responsible for his massacre on the characters Wingnut and Screwloose homeworld Huanu, and destroying all life on a planet known as Hyrobl.

Despite his frail appearance, many other villains fear Krang, including Shredder, who denies this, Bebop, Rocksteady, and Baxter Stockman (before he crossed mutated into a humanoid fly) Krang is known to have several enemies other then the TMNT and Splinter, this includes Shreeka, a Dimension X criminal who is wanted in thirteen galaxies and was Krang's old partner in crime (and possibly an old girlfriend), Maligna the Malignoid queen, and Lord Dregg, an evil alien warlord and villain of the last two seasons of the series. Despite Shredder's obsession with the Turtles and Splinter, Krang doesn't see them as mortal enemies, but as minor setbacks who need to be destroyed. However, he still hates them for foiling his schemes meaning he is simply better at not letting his temper get the best of him.

While many of his later incarnations are much more dangerous, Krang is fairly comedic during his debut during the 1987 series. While very sadistic, he is also arrogant which is part of the reason the Turtles foiled so many of his schemes. He is also less of a threat outside of his suit.



  • It was revealed in the New York 2015 Comic Con that Krang would appear in the 2012 series season 4 along with the 1987–1996 series Turtles.​ The episode aired in late-March 2016.​
