He was originally Uranai Baba's strongest fighter, but was bumped down one rank by Grandpa Son Gohan. His Akkumaito Kousen has the unusual ability to make people explode into pieces by expanding the evil inside of their heart; apart from that, his skill as a fighter is unbelievable, having won the Tenka-ichi Budokai twice in the past. He gave Son Goku a run for his money and tried to blow him to shreds, but unfortunately for him, he didn't know that Goku had a pure heart. He returns in Dragon Ball Z to give his energy to Goku's Super Genki Dama. His name is a pun on Akuma (悪魔 "devil").
