...........ok.......I got this idea staring at a poster my sisters have just sitting on the wall of Anna, Elsa, and Olaf.......

So Izuku's quirk would be called Snowman

He is a snowman who is very childish

He can create a small blimp of clouds to keep himself from melting

If he does melt he just has to be put into a cold environment to reform

He can create some bursts of ice to do damage

......I'm having mixed feelings about some of these ideas now....
