Started as a random being, but then he just started training. after a day, he made a chamber that was unbreakable, and within a graham's number of years becomes 0.0000000000000000000000000000000000000000001 nanoseconds outside. He spent a quadrillion years in the outside world trying to achieve infinite power, then realized Infinity was puny compared to his current state. He came out, decided to rip reality, and noticed by moving his fingers he could control reality. A simple sign would destroy existence and revert everything into The Beginning. He was Destruction. By the way, he can destroy a graham's number of omnipotent beings without really trying... except he still notices it because he is all seeing. Omnipotent beings are supposed to be invincible, but gods don't do logic.
