Doomsday is an ancient, Kryptonian deformity created by Lex Luthor using General Zod's remains in an attempt to kill Superman. The creature proved extremely powerful, being completely unharmed by a point-blank nuclear detonation and capable of easily holding his own against the combined might of Superman and Wonder Woman. Only when Superman sacrificed himself to impale Doomsday with a Kryptonite spear was Doomsday finally killed.
