Fifteen years have passed since the events of Dragon Ball GT and the world is enjoying a reign of peace. This peace is, however, shattered when a monster named Haifeiru lands on Earth. Haifeiru appears to be searching for the dragonballs.
During his search, he comes across Vegeta's descendant, Vegeta Jr.. Their meeting erupts into a fight, and Vegeta is shocked when he realizes that Haifeiru can withstand his attacks without much, difficulty. The match comes to a halt as Haifeiru picks up another high Power Level. Presuming it to be a stronger opponent's, Haifeiru flies off in the direction of the new Power Level, abandoning the match with Vegeta.
