Devil

The Devil is a being that inhabits the Underworld, who has been there for eternity. He knew nothing at first, but soon learned many things. He has infinite mental capacity, and thus can know an infinite amount of things and people, and is immortal. He can also freeze time for himself while time continues to flow around him, improve people's mental capacities, teleport anywhere in the Underworld, and bridge the gap to other universes, only if they were created for him.
