This what if takes place during the tournament of power and had buu in place of tien. Universe 9s trio de danger is also not eliminated by goku and vegeta beating buu to a stand still nearly knocking him out. Buu becomes incredibly angry and his evil half splits away from him but instead of his evil half winning. The good half does.

Begin the what if short

Bergamo, Basil, and Lavender has just completed a long and enduring battle against majin buu. They managed to defeat him with a group attack. Lavenders poison did most of the work mostly negating buus regeneration abilities.

Lavender laughed as the majin barely stood on his own. "Hehehehe looks like my poison was took much for him!" He shouted as he chuckled a little

"I wouldn't be so sure" Bergamo said. Something felt off and everyone had noticed buu roared before he split into two. His good and evil halves glared and then began to battle one another before buu suddenly enveloped his evil half. The grey and pink slime matted around in a ball before a large bright light erupted in the arena. As the smoke cleared a taller more muscular majin stood before them and laughed a little. "You made Buu mad. Now buu gonna kick your ÀSS he shouted before powering up. His energy in his new super form didn't seem evil but but not the same as before. He chuckled crossing his arms facing the trio of brothers. "Well. Don't make Buu wait to long. That only make buu madder" he said before powering up as the battle resumed
