Fictional character biography The embodiment of entropy, Imperiex takes the form of pure energy contained inside a colossal, humanoid set of armor. Since the dawn of time, he has repeatedly destroyed the universe to create a new one from the ashes of the old. He is first mentioned when Mongul II arrives on Earth stating that Imperiex has destroyed his Warworld and is heading for Earth. Mongul convinces Superman to help him fight Imperiex, and the two apparently manage to defeat it.
