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.
Gyaos is a powerful Kaiju but tends to get overlooked next to the stronger ones. He still has one of the best designs though. Either way none of that will be enough to stop Bunny here. Bunny has super strength and moves really quickly while in his powered up mode. Gyaos won’t be able to keep up and while his defense is good enough to endure this for a while, he won’t be able to hang in there forever. Ultimately with no way to counter attack, his time will be up. Bunny wins.
