In the 1987 Teenage Mutant Ninja Turtles cartoon background story, Krang was originally a warlord from Dimension X who commanded an army of Rock Soldiers under the leadership of General Traag and Lieutenant Granitor. He took the completed Technodrome (a powerful mobile battle fortress) for himself, and then banished Drakus (who helped Krang build it) to Earth. Eventually, Krang would be banished from Dimension X as well, but not before being stripped of his body and reduced to a brain like-form. It is revealed in a later episode that he originally belonged to a species of reptilian like monsters, similar in nature to a T-Rex.
