Super Buu is the strongest of all the Buu Forms. He is also the coolest one of all. He was realeased from Majin Buu's body in a rage of anger. Super Buu is Majin Buus anger that was subdude by Mr. Satan. Mr. Satan was a vital part of Super Buu's existance. Think about it, If Mr.Satan wasn't shot, Majin Buu would not have gotten angry and realesed our beloved Super Buu.
Majin Buu's another form of the all-mighty Buu. He is the original form, the first to show up. As you can see he is the fat one out of the three forms. He was one to release Super Buu after his friend Mr. Satan was shot. At first, Majin Buu was originaly evil but switched side due to Mr. Satan.
This is actually Super Buu in a smaller form. He is mighty strong and he is pure evil. He beats up on vegeta in this form. This Buu is one cool kid haha.
Chocolate is probobly the funniest and coolest Buu out there. His fighting style is boxing and his favorite food is (as if you didn't know) chocolate. His boxing skills are amazing. Not even SSJ Gokou could match it. This Buu kicked Majin Buu's ass. He practicaly used him as a punching bag. Then it was Gokou's turn to get pummeled. He is a shining example of how strong the Buu's really are!
