I can change into reed richards, imagine that having his intelligence. But i would use this power to get Reed’s intelligence, Thor, & even eternity 😈 man ima be god. Or better infinity Ultron powers
I think I would create machinery (bio, etc.) to augment myself to make myself OP, while also taking possession of some of the infinity stones as well. I would then just enjoy mylife and see if I can travel the Omniverse.
