Iceman possesses the power to instantly decrease the temperature of ambient water vapor in his immediate environment to below zero degrees Celsius, thereby freezing it into ice. He is able to make ice that will not break unless he wills it to. In this manner he is able to quickly form a great variety of ice structures, including projectiles, shields, ladders, baseball bats, etc. He often makes ice slides which form rapidly beneath and behind his feet, moving him along the slick surface at high speeds.
