Well... *Deletes some of your memory, you no longer know how to control Omnipotence nor can you ever remember having it*
We now have somebody who is Omnipotent, but doesn't know he is too. While I have Nothingness Manipulation (Which is basically power over non-existance)
This would actually make for a pretty good story, a bunch of demi-god tier protagonists and their Omnipotent friend, who the Nothingness Manipulator removed the memory of ever being Omnipotent from... Nah, who am I kidding. It would be a crap story... It would be a good piece for potential kek though.
HAHAHA I can create solar systems, summon warp storms, crap lightning, and I can even manipulate other peoples abilities. I AM CHAOS INCARNATE!
