Time Loops Suck

Class 1-A is stuck in a time loop... Aizawa joins in the 10th loop, All Might joins in the 13th loop.. instead of Mineta... it's Shinso? Everyone is confused. They go through their 1st to third year Evey loop.. unless the some how die, then, they just get sent back earlier?

Ah, yes. Messing with villans is something they do to just pass time. Pranks are a regular thing.

What if Nezu looped since the beginning? Just never told them. He sits back, and enjoys every single one. Never interfering.
