Ok I've got an idea from where to start and sht and how to continue.
just need to ask something. when God meets madara. madara will wish for his limiter to be removed. meaning every fight he gets in he will progress further getting stronger as the fight goes this way he will be op but there will be fight scenes. a perk given to him by God will be that he cant be erased by higher beings. (he will have all his powers before that aswell meaning sasanoo)
