Iceman (Super Ice Slide)
"Iceman has the mutant ability to turn himself into a being of living ice. Once he does that, he can create almost anything he wants: ice slides, ice weapons, ice shields, not to mention icicles and snowballs. And when he really concentrates, he can create a blinding snowstorm even in the middle of July! But most important of all, the X-Men know that no matter how hot the battle, Iceman always keeps his cool."
