Uub
Uub is a small Indian boy who came from a far-off village to compete in the Ten'kai'chi Bou'dou'kai, as his village needed the prize money to pay for supplies and food. What he was at first unaware of is that he is a culmination of a wish made by Goku on Kaioshin-kai. Uub is the re- incarnated form of Majin Buu. He is a small prick in appearance but he has the strength, skill, and speed of Kid Buu. Uub is the exact opposite of Majin Buu: he is not evil. In Dragonball GT Uub fuses with Fat Buu and becomes Uub-Buu, who is as strong as Goku or Vegeta in Super Saiyan 4.
