A resurrected Michael would use fast forward to avoid dealing with an inhumanely strong & fast child.
You keep thinking that the remote's fast forward option can make him batman & that's partially valid. But you're not directly countering my arguement of the no limits fallacy.
I'll give an example. 2 characters have
reactive evolution or reality warping. Theoretically, they should stalemate, but having better evidence that proves which use/potency of said ability is better would give the entity with better use/potency of said ability an advantage.
Michael's fast-foward button has been shown to make him a fat rich CEO &
obey Michael's commands. So at best, he's going to be some cool, athletic general of a military.
Frisk is capable of befriending or even killing the entirety of the Underground in Undertale on their own. They're also way stronger & faster than any human. How does that compare to being some sick general?
As always, I can always edit the battle conditions to deal with the preparation gap if it becomes a problem.
