these are the different forms of Majin Buu

Evil Kid Buu when fights the 5 Kaiou-shins, absorbs them all, except for North Kaiou-shin, the Kaiou-shin we see in the show. When he absorbs I think West Kaiou-shin[correct me if i'm wrong], who was really big and strong, he got really big and strong. But then, when he absorbed Dai Kaiou-shin, who was really fat and nice, we get Fat Majin Buu, the Buu that is resurected By Babi-di, Bibi-di's father.

When Fat Buu, befriends Satan, he basically becomes the Good Fat Buu, that winds up saving Gokou and the rest on Kaiou-shin Kai[Kaiou-shin's planet], and then goes on to be a good guy in dbgt. But when his dog gets killed, he gets so mad that he splits into 2. One, the pure good and fat Buu, the other, the skinny Evil Buu. Evil Buu beats Good Buu, then eats him, and becomes Super Buu.

Super Buu absorbs Piccolo and Gotenks, to become something like "Super Buupenks" and then absorbs Gohan to become something like "Super Gobuupenks". Then, he absorbs Vejitto as well.

When Vejitto is absorbed, Gokou and Vejita split back to themselves, and they free everyone that has been absorbed by Buu. When they do this, the only thing that is left of Buu, is the original Buu, before any of the Kaiou-shins, or any of the Z team was absorbed. *Note, I used absorbed for most of the time, when he ate some of the people, so don't mind that*
