Dragon Ball GT 2

Five years have passed since he flew away with Uub, the reincarnation of Majin Buu, to train him; and now Goku, due to an unforeseen circumstance, has returned to being a child. The adventures follow one another, as do the battles and the enemies. Following the clash with the cruel and powerful Super Cyborg 18, many have fallen, and to bring them back to life our heroes gather the Dragon Balls as usual. But something does not go as planned: humans have expressed too many wishes, and the spheres have become polluted with negative energy, giving life to seven new evil dragons that spread throughout the world bringing terror and destruction.
