So my theory about this story is. all of 1A stutents went back in time to dear old bodys form the first day in UA with all of dear memories and powers.
So, if Aizawa had been there with AFO, it would've been over. AFO's been able to live so long because of a quirk that extends his lifespan. Once erased, all those years would catch up to him at once. He'd become 130 years old in the blink of an eye. Only lucky coincidence kept Aizawa and AFO from being on the same battlefield all this time.
@@Sniper-rr2zx No. Mutations are things like Toru's invisibility, Ojiro's tail, and Tsu's frogginess. The life extension quirk had no physical affect. Also, Aizawa *can* erase mutant quirks, but he can't erase the mutation. If he erases Ojiro's quirk he's no longer able to use his tail, but the tail doesn't go away. If he erases Tsu's, she won't be able to wall-climb or stick out her tongue. The only reason he can't erase Toru's quirk is because he can't see her.
