Iceman is one of the most powerful mutants on the planet, and his ice-powers essentially mean he can manipulate the entire world's atmosphere. But Uncanny X-Men #314 reveals there is another element of his powers, one that has never been explored since; he has the potential to be a shapeshifter as well.

What level mutant is Iceman?

As mentioned by writer Mike Carey, Iceman is "an Omega-level mutant ... [and] has powers that can influence the ecosystem of the entire world." Iceman has yet to tap into his full mutant potential, but over the years he has taken more interest in developing his abilities.

Can Iceman be killed?

Iceman is virtually indestructible in this form: he can reform his shattered body, and even if the rest of his body is completely destroyed. Iceman has shown that his control over his powers are so great, that he simply cannot be killed.
