Deku’s original costume was sort of like a Bunny and this guy’s got that name so the matchup was perfect. Bunny is a strong hero who always does his best to achieve his goals but at the end of the day his physical enhancement ability isn’t quite up to par with Deku’s strength quirk. Deku’s power is much greater than that of Bunny’s and he will be able to very quickly secure the win here. He can move faster than Bunny can perceive him. Deku wins.
