Majin Buu

Majin Buu (Japanese: 魔人ブウ, Hepburn: Majin Bū), generally spelled Majin Boo in subtitles of the Japanese anime, and rendered as Djinn-Boo in the Viz Media manga, is a fictional character and final antagonist in the Dragon Ball manga series created by Akira Toriyama, before the release of Dragon Ball Super. He made his debut appearance in chapter #460 "Majin Buu Appears?!", first published in Weekly Shōnen Jump magazine on March 1, 1994. Majin Buu has had multiple origins throughout the series. Canonically, he is a genie-like magical life form known as a "Majin," created by the witch Marba after being asked by Bibidi, due to him not having the ability to do so. In Dragon Ball Z, he is explained as being a creation of the evil warlock Bibidi, who is unleashed by his son, Babidi, onto Earth. Alternatively, In a later interview, Dragon Ball's author Akira Toriyama states that Buu had existed outside of Bibidi and that Bibidi simply knew how to summon Majin Buu.

Majin Buu was sealed away by Bibidi and brought to Earth; however, whilst being sealed away, Bibidi was killed and Buu remained sealed away and dormant. During the events of Dragon Ball, he is revived by Bibidi's son Babidi in order to continue his father's plan to conquer the entire universe.
