The last villain of the Dragonball Z saga. Created by Bibidi and resurrected by his son Babidi using an enormous of saiyan energy, gathered from Gohan and his fight with Majin Vegeta. The names of these three characters are a reference to Cinderella; Bibbity, Bobbity, Boo!

When Buu first appears out of his Ball that he has been sealed inside for a million years (according to Babidi), he acts very childish due to his absorbing of the Grand Supreme Kai: Daikaioh.

Ironically, in his original state (called Kid Buu) he is more powerful than any other of his fused states, due to his natural, deep-seeded need for destruction and without Daikaioh's good influence, he becomes and unstoppable killing machine, blowing up planet after planet, resulting in him being blown to smithereens and reforming.
Majin Buu (in his kid buu form) had to be defeated with a spirit bomb containing the energy of every person on earth (or at least, all the fans of Mr. Satan (Hercule)).

Majin Buu is a giant fat pink monster from the dragonball z series. he has the consistency of play-doh and turns people into candy using the weird tentacle on his forehead. he starts out as a villain, but eventually becomes a good guy. also, he has the most annoying and incomprehensible voice in the world.
Majin Buu: Buu no like you!

Gohan: WTF?!

Buu: WHEEEEEEEEE!!!! (starts running around in circles)

Gohan: Ooookay, i'll just kill u now. (blows up buu's head)

Alternate spelling of Majin Boo. He is the fat pink dude on DBZ who likes to eat things that used to be people. He likes doing the fat all day long with his rubber ducky and inflatable Yoshi doll. Can also be called Stupid Buu, Retard Buu, or The Load of Fat.
Majin Buu reminds me of a girl in my 6th period class...
