Dragon Ball Super: Godslayer

He transmigrates into a new timeline. During a sparring match between Son Goku, Vegeta, and Beerus, one of their blows accidentally left Beerus with only one arm. This provoked the dissatisfaction of the eleven Gods of Destruction, the Grand Priest, and Zeno. The Gods of Destruction slaughtered the families of Son Goku and Vegeta, so the two fused into Vegito and went on a rampage, killing gods in their home universe. When they reached Universe 10, they obtained the Time Rings and began traveling wildly through time and space. They found a suitable universe, summoned Super Shenron, and became immortal. At last, they slaughtered the Grand Priest and Zeno, becoming the new gods of that universe.
