UUB

Uub is a fictional character in the Dragon Ball manga and anime series created by Akira Toriyama. He is introduced as the human reincarnation of Majin Buu, the villain from earlier arcs. Uub first appears at the end of Dragon Ball Z when Goku encounters him during the World Martial Arts Tournament. The elder Kai explains that the essence of Kid Buu resides within Uub’s body, though Uub has a pure heart and can choose to use that power for good.

Motivated by a sense of justice, Goku resolves to train Uub to become Earth's protector. Uub is depicted as humble, kind, and highly determined, with strong potential in martial arts and ki control.

Under Goku’s guidance, Uub trains to improve his fighting abilities; his power and skill are shown to grow through effort and discipline. He is intended to be the next generation's defender of Earth, representing the future of the series' martial arts tradition.

Beyond the main manga and anime, Uub has appeared in various Dragon Ball media, including video games and non-canon materials. His canonical role remains centered on his introduction at the end of Z and his training with Goku, making him one of the series’ notable successors to the series’ legacy of Earth's fighters.
