Majin Buu

Majin Buu (魔人ブウ, Majin Bū?, also translated as "Majin Boo") is a magical life form created by the wizard, Bibidi, billions of years before the events of Dragon Ball took place. He is eventually sealed by Bibidi after he becomes uncontrollable, and Bibidi's son, Babidi makes it his goal to revive Buu. After being released, Buu appears as an innocent looking pudgy pink genie-like creature. He is very naive and easily influenced, and he has a very volatile balance between his gentle and evil sides. After Buu kills Babidi, he becomes close friends with Hercule, which eventually causes him to expel his evil side. This evil manifests, and it manages to defeat and absorb the good side, resulting in a tall, slender form, who calls himself "Evil Buu." He is interested in a challenge, and later goes on to absorb Goten and Trunks as Gotenks, Piccolo, and Gohan.

It is revealed by the surviving member of the Kaioshin that the fat form of Buu is actually the result of the original assimilation of their leader into his body. The original is a sleek, child-sized being who is obsessed with chaos and destruction. The original is restored after Goku and Vegeta remove the good side from Super Buu. The good side is later spit out by the original, and he goes on to live with Hercule on Earth, while the original is killed by Goku, who wishes for him to be reincarnated as a good person. King Yemma, hearing the wish, reincarnates him into a child named Uub.

All forms of Buu have a rubbery body that is easily damaged. He can regenerate instantly from any wound, regrow any part of his body, and he can even restore himself from vapor. It is possible for him to become so worn down that his regeneration begins to fail. He can reconfigure body portions into weapons, including stretching his extremities. Buu also can heal damaged beings, shapeshift, and transfigure other objects and organisms. He can also absorb other organisms by enveloping them with his body, and can replicate fighting techniques, even after witnessing them once.

In the original Japanese Buu and all his forms are currently voiced by Kōzō Shioya in all media. In the Ocean Studio dub Scott McNeil would voice Fat Buu, Brian Dobson would voice the Evil and Super Buus, and Ward Perry would voice Kid Buu. McNeil would voice the renamed Mr. Buu in the Blue Water dub. In the Funimation dub Josh Martin voices Fat and Kid Buus, and Justin Cook voices Evil and Super Buu. Martin and Cook voice Buu in all video games with exception of Dragon Ball GT: Final Bout where Buu, in kid form, was voiced by Dougary Grant. Buu was rated by Wizard magazine as the 40th greatest villain of all time.[13] David F. Smith of IGN states that although he is tough, Majin Buu's pink complexion prevents anybody from taking him as a serious threat.[14]
