"I'm willing to bet that if Iceman manipulated his size to become some gigantic ice monster, he'd even throw The Hulk into space lol, didn't someone say that icemans potential can even allow him to teleport eventualy ?"
He actually performed both of those acts in AoA:
- increasing his size, and strength, by taking in moisture from the surrounding air.
- travelling great distances in a matter of seconds by "moisture molecular inversion".
Iceman gets a solid 9:
- Present 616 Bobby is getting so good that he can control the enthalpy of chemical reactions.
- Plummit environments to sub zero temperatures within a matter of seconds.
- Reconstitute his form after being blasted into pieces (in his ice form).
- Heal any damage sustained to his flesh form by converting to his ice form.
- Almost instantaneously resolidify after being vaporised , experiencing minimal side effects to his biochemistry (although at present this is extremely mentally taxing).
