Empra appears in both Demikids Light Version and Demikids Dark Version, but only speaks and is fought in Dark Version by Akira and Gale. He rules Valhalla and has created severe unrest among the demon world. In his quest he has destabilized time, causing the time rifts shown all over the game. His goal throughout the game is to conquer the realm of Dem and Lucifer, control Valhalla, and the time tower, then spread into the human world until he controls it all.
