I don't have any friends.
hobbitx you are partially right, Iceman can freeze CO2 as well, but it goes further.
Iceman doesn't need H2O. At the fullest extent of his power Iceman can freeze more than just water. Way more. He can freeze any gas or liquid by reducing it's temperature to absolute zero. He could solidify hyrdogen, but not for long. The higher the substances initial temperature, and the lower the melting point, the harder it is to freeze an element, and the faster it melts.
This does not mean he can beat everyone. Most of the people mentioned can beat him. Bishop is another case. Iceman does not emit cold energy. cold is not energy, its a lack thereof. So essentially, Iceman absorbs energy in immense quantities, heat energy to be exact. When he absorbs most or all of an object's heat energy, it freezes. Bishop would have is hands full with Iceman, he doesn't emit any energy for Bishop to absorb.
