Mephias

Mephias was an evil demon shaman who became Shaman king hundreds of years ago. He was killed. He might have been defeated by a young Goldva. He had two guardian ghost's they were a spider and a dragon. Their names were unknown. He and his guardian ghosts made him invincible. He only caused chaos as Shaman king. He is strong enough to destroy Asakura Yoh but he would probably never help.

Mephias appears in Shaman King: Master of Spirits and reappers in Shaman King: Master of Spirits 2 for game boy advance.
