WHAT-IF during the battle against Overhall, Mirio dodged the Quirk-Erasure bullet, avoiding the loss of his quirk?

As the battle progressed and Eri grew more excited, her quirk activated, but instead of rewinding Mirio's existence, she instead unconsciously fast-forwarded his quirk, granting him a potent increase in strength.

Sadly, with the strengthened quirk came the future Mirio's shadow, a will that made up the essence of his future self...

With a powerful quirk, a quirk he could not control, Mirio permeated through the barriers separating the Multiverse, finding himself in a new universe - The Marvel Cinematic Universe.
