Fat Buu, is the kid-like creature that is lovable, but at the same time is a complete badboy. How'd Majin
Buu get so...... kooky?
Evil kid Buu, was originally created by Bibidi, father to Babidi.
Evil kid Buu, set to destroying the world, but the kais tried to stop him.
As Majin Buu absorbed more kais, his evil was smothered more and more. So, the pattern is as follows:
Evil kid Buu -> Super Buu-> Fat Buu
Majin Buu was influenced by Hercule and stopped killing. Now, Majin Buu lives in a world, with people who
have no idea he even killed them.
