Dragon Ball - Zeroverse

Several years have passed since Goku first took Uub under his wing, and the young warrior has grown remarkably strong under his mentor’s rigorous guidance. Satisfied with his student's progress, Goku decides it is time to truly test Uub’s abilities by entering him into the next Tenkaichi Budokai tournament. However, unbeknownst to the fighters preparing for the martial arts competition, a sinister threat is quietly gathering strength in the shadows. A mysterious adversary originating from Universe 0—a realm predating the broader multiverse conflicts—desperately seeks to cross over into their reality. To achieve this impossible feat, the entity requires the ultimate wish-granting power of the Dragon Balls. Setting a dark plan into motion, this unknown enemy revives the wicked sorcerer Babidi to help secure them. Exploiting the latent darkness hidden deep within the young fighter, Babidi awakens the dormant remnants of Majin Buu sleeping inside Uub, twisting the boy into a mindless puppet under his control. With Uub corrupted and the Dragon Balls targeted, Goku and his allies must unite to thwart this dangerous scheme, fighting at all costs to prevent the invader from breaching the boundaries of their universe.
