Majin Buu was conjured into existence long ago by the evil wizard Bibidi. A powerful fighter who has destroyed many planets in his past, Majin Buu’s body is rubbery giving him great advantage in battles. He has now been unleashed by Bibidi’s son, Babidi, to destroy Earth. Like many of the bad guys in Dragon Ball Z, Majin Buu exists in multiple forms. The series starts off with child-like Majin Buu, in his more evil being called Evil Buu and in an even more powerful form called Super Buu. He is in his Evil Buu form very briefly before transforming to Super Buu. Child-like, Majin Buu does not have a strongly developed sense of good and bad. He agrees to stop hurting people when he discovers it bothers Hercule. Unfortunately the threat to Earth is not over. For from Majin Buu, Evil Buu emerges. He manages to survive until the end of DBZ, becoming best friends with Mr. Satan, and competing in the World Martial Arts tournament.
