While imprisoned on Neutrino, Kraang hires the bounty hunter Hakk-R to eliminate several material witnesses in order to get the trial cancelled, but Hakk-R fails thanks to the efforts of the Turtles. When the Turtles learn of Krang's genocidal plans thanks to their human friend April O'Neil, a former intern at Stock Gen, they, together with their ally, the Fugitoid (a former Neutrino scientist whose mind is trapped in a robot body and who was forcibly conscripted by Krang to complete his terraforming machine, the Technodrome), and the Foot Clan stop Krang from destroying the Earth, and the Utrom warlord is surrendered to the Neutrinos for trial for his numerous war crimes. It is through Stockman's experiments that the Teenage Mutant Ninja Turtles and Splinter evolve into intelligent, humanoid mutants. In order to augment his troops, Krang, initially disguised as a despotic human warlord, forms a business relationship with Baxter Stockman, head of the genetics research institute Stock Gen, and supplies him with Ooze, which could be used as a natural mutagen on Earth's organisms. Krang, who was as brutal as his father but opposed his uncautious politics, fled with a few survivors of his people through an interdimensional portal to Burnow Island on Earth, where he established a base from which he intended to terraform this world into a new home for his people. However, his megalomanic expansion drive both deprived his home planet of its most essential natural resource, the Ooze, and incited rebellion among the subjugated people of Dimension X, eventually leading to the destruction of Utrominon. He is the heir of Quanin, the former Prime Minister of the Utroms' ruling council who appointed himself Emperor and aggressively expanded the Utrom domain into an empire. In the IDW Comics Krang is both an Utrom and a denizen of Dimension X. Krang's physical appearance was inspired by the Utroms from the original TMNT comic book. In the final season of the 1987 animated series, Krang showed signs of psychic powers when he hypnotized one of Lord Dregg's soldiers into obeying his and Shredder's commands, saying it would only work on weak-willed people. In the 2012 series, Krang is not Krang, but "the Kraang" and is a plural name for a species of aliens. Krang was created by David Wise, with inspirations from the Utroms, to supply the Shredder with extraterrestrial technology. The character made his first live action appearance in the 2016 sequel, Teenage Mutant Ninja Turtles: Out of the Shadows, with his voice provided by Brad Garrett. He is still one of the primary antagonists to the Ninja Turtles, appearing as General Krang in the 2012 IDW comic publication.
In the 1987 TV series, Krang was voiced by Pat Fraley. 1, #1, published by Archie Comics in August 1988. Krang's first comics appearance was in Teenage Mutant Ninja Turtles Adventures vol.
