3. Iceman

Admittedly, Iceman’s power levels have been depicted as being all over the place but, at his most powerful, he is an absolute beast and a massively underrated and underestimated character.

On the face of it, his power – which is essentially complete control over water vapour and ice – doesn’t seem like much, but when you also consider that the scale of his power is massive and that water can be found abundantly in every living object, you realise he’s extremely dangerous.

An Omega-level mutant, Bobby Drake has frozen every water molecule in characters as powerful as Legion – meaning he could easily do exactly the same to someone like Hulk.

Thor – a hugely powerful character who has fought and defeated countless Frost Giants – has admitted being fearful of Iceman’s power and Iceman has even created ice so sharp that it has badly injured the Asgardian hero.

Iceman can turn his own body into solid ice or water vapour – the latter of which makes him nigh physically unkillable – and, even in his normal form, he can heal from damage instantly using his power.

Such is the scale of his power, he can freeze entire environments in seconds – including Hell itself (yes, Bobby Drake has literally made Hell freeze over).

He could freeze Hulk’s brain or entire body with a mere thought – and he has actually trapped Hulk in a block of ice that he couldn’t escape from on-panel.
