In Dragon Ball Z Before the events of
Dragon Ball, as revealed in
Dragon Ball Daima, Majin Buu came into being when Bibidi commissioned the Demon World witch Marba to create a being that existed "solely to slaughter and destroy." Within a few years, taking credit as Buu's creator, they destroyed hundreds of planets. Buu later reached the world of the Kais where he killed two of the five
Supreme Kais who govern the universe. Their leader, the Grand Supreme Kai, and his apprentice, the Southern Supreme Kai, attempt to fight Buu despite being weakened from dealing with a separate threat earlier. Buu manages to absorb the two Supreme Kais, but the absorbed Grand Supreme Kai's influence dulls the Majin's destructive nature and turned him into his current form. But Buu was still too ferocious even for Bibidi to control, resulting in the Majin being temporarily sealed and moved to their next target, Earth. When Babidi threatens to re-seal him, Buu begins to obey his orders and destroys and kills everything and everyone in sight to get Piccolo, Trunks and Goten to come out of hiding. That is until Goku asks him why he lets Babidi boss him around, leading to Buu killing him, however he continues his mischief and destruction, unaware that what he is doing is wrong. Majin Buu attacks humans, destroying nearly all of the world's population, then builds a house by converting people into clay. He is resting in his house when
Mr. Satan befriends him while waiting for an opening to kill him. The friendship coupled with the affection from a dog he healed, has Buu resolve not to kill anymore when two civilians shoot the dog and then Mr. Satan. Gohan then arrives and clearly has the upper-hand over Super Buu, but Super Buu absorbs Gotenks and later Piccolo. Now stronger than Gohan, Super Buu, knowing that there is a time limit on Gotenks's fusion, planned ahead and can absorb Gohan as well. Though the Potara Fusion ran its course, Goku and Vegeta manage to retrieve Gohan, Piccolo, Goten, and Trunks before they completely separate the absorbed Fat Buu from Super Buu. Buu is initially overwhelmed, though he becomes enraged over seeing Mr. Satan injured by the battle collaterally and quickly overpowers Basil. After consuming a drug that increases his power, Basil seems to gain the upper hand on Buu with a buffer form coinciding with his attacks; however, Buu is unaffected by the attacks and defeats Basil with a Kamehameha wave. Buu then heals Mr. Satan. After the mini-tournament, Buu begins to train on Earth for the Tournament of Power. Due to the intensity of his training, Buu gains a slimmer and toned body and spars against Goku, beating him. Alas, also due to the intensity of his training, Buu falls asleep and will not wake for 3 months, forcing him to miss the Tournament of Power.
Frieza is temporarily resurrected to fight in Buu's place. Shortly after the events of the Tournament of Power and
Dragon Ball Super: Broly, Buu is kidnapped by the Galactic Patrol and taken to their headquarters alongside Goku and Vegeta. Merus, the Galactic Patrol's #1 elite patrolman, explains that an evil criminal named Moro has escaped from galactic prison an the Galactic Patrol need the Grand Supreme Kai, revealing that he and the Southern Supreme Kai sealed Moro before they got absorbed by Buu. As Goku and Vegeta went away to confront Moro, Buu is taken to New Namek where the Grand Supreme Kai's mind subverts Buu and uses the Majin's body as his own. The Grand Supreme Kai reveals he cannot seal Moro away since he lost his god
ki, which Kid Buu possessed when he fully separated from Buu. For the remainder of the arc, the Grand Supreme Kai remained dominant over Buu's body. At the climax of the fight, he collected god
ki from an oblivious Uub and sent it to Vegeta, who then later transferred it to Goku so Moro can be killed for good. The Grand Supreme Kai returns to his deep sleep soon after, with Buu oblivious to all that transpired.
