Majin Boo (魔人ブウ, Majin Bū) is a fictional supervillain who first appears in the Dragon Ball manga created by Akira Toriyama. As the manga was adapted to anime, it was split into two sub-series; Boo appears in the second sub-series called Dragon Ball Z, and a third anime-only sub-series called Dragon Ball GT. Following the success of Dragon Ball, he also makes a minor reappearance in Toriyama's self-parody called Neko Majin Z.
