Krang

Krang (also spelled Kraang) is a fictional supervillain appearing in Teenage Mutant Ninja Turtles-related media, most frequently in the 1987 animated series and its associated merchandise, such as the Teenage Mutant Ninja Turtles Adventures comic book and most of the classic TMNT video games.

Krang's first comics appearance was in Teenage Mutant Ninja Turtles Adventures vol. 1, #1, published by Archie Comics in August 1988. In the 1987 TV series, Krang was voiced by Pat Fraley. He is still one of the primary antagonists to the Ninja Turtles, appearing as General Krang in the 2012 IDW comic publication. 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.

Krang was created by David Wise, with inspirations from the Utroms, to supply the Shredder with extraterrestrial technology.

In the 2012 series, Krang is referred to as Kraang Prime, and is the leader of a rogue hive mind faction of Utroms known as "the Kraang".

In Rise of the TMNT: The Movie, Krang is referred to as Krang Leader (credited as Krang One), who leads his siblings, Krang Sister (credited as Krang Two) and Krang Brother.

Iago PUC's ideas

 * Krang appears in in the Disney+ crossover miniseries Marvel's All-Star Multiverse, voiced by Steve Blum. Appearing in "Chariots of Fire", he engages on a turf war against Loki for dominance of Mustafar. This also puts him in conflict with Blaze the Cat and the Alliance leaders (Spider-Man, Captain America, Iron Man, Thor, Sonic the Hedgehog, Leonardo, Rey Skywalker and Optimus Prime), who arrive on Mustafar to stop them.
