Dragon Ball: the Strongest Majin Buu

Travel through time to become Majin Buu, start killing Babidi, liberate Majin Buu's true power, and dominate every universe, every dimension, every time and space. Beerus, the God of Destruction, is afraid; you cannot kill me, I am the God of Destruction. Buu is just a piece of trash in front of me. Majin Buu devoured Buu from countless parallel worlds, transformed again and again, and finally got rid of the title of Majin and became the supreme and invincible demon god.
