Majin Buu , generally spelled Majin Boo in subtitles of the Japanese anime, and rendered as Boo the Djinn in the Viz Media manga, is a fictional character and one of the main antagonists in the Dragon Ball series by Akira Toriyama. 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. 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, Toriyama states that Buu had existed outside of Bibidi and that Bibidi simply knew how to summon him. The 2024–2025 anime series Dragon Ball Daima reveals that Buu was created by the Demon World witch Marba when she was commissioned by Bibidi.
