mechikabura

A former rival to Chronoa and the leader of most of the demons in Dragon Ball Heroes. He initially appeared as an old man, but used the dragon balls to make himself younger. He is often referred to as the "Dark King" and is the original creator of Dogidogi.
Following his supposed death, he often appears in the conscience of whoever is given his "Dark King" powers in an effort to find a new body to control. He has yet to succeed.
