First, there are way too many combatants. Read the forum rules. Second, assuming we are talking about 'god' iceman, he would immediately pretty much destroy anyone who didn't have an INSANE level of durability. He's been pitted against the best, and has come out on top in these forums. It's kind of sad, but Iceman truly could be a match for all these by himself.
