Recovery Girl is younger in this one - She has OFA instead of All Might (He doesn't exist)

Izuku has a regeneration/healing quirk

Izuku's quirk - Phoenix: The user heals both themself and other via flames that are generated by the user's wings. The fire can't be used as traditional fire unless interacting with a non-living object.

Izuku's hero name: Asclepius

(Give me some suggestions for this - Extra plot, friendships, ship, etcetera)
