Ice Winxes are humanoid creatures that are able to conjure ice in all it's forms. They despise mankind, but they coexist with them. That won't stop them from killing said humans if they wrong them. Shoto Todoroki is a strange case, he is both an Ice Winx and a Fire Sprite, creatures on opposite ends of the spectrum. His Mother is an Ice Winx, and his Father is a Fire Sprite, so he can use both fire and ice. He's stoic, blunt and dense, but at the same time. He's a huge sadist.
