I would be super awesome with mind powers that can mind fuck you so hard that you shit ur pants then start crying and run home, terrified so much that eventually would become a vegetable zombie which of course would be under my control.
So basically Id have a zombie horde roaming over the world and all those who oppose would be eaten alive. People would call me "Dictator of the universe", but eventually also "The Holy Mind" since I would create a world of peace and harmony in which all humans would have the same rights and privileges, an unchanging balance called Equilibrium.
Yeah cool story.
