Iceman (Robert Louis "Bobby" Drake) is a fictional superhero appearing in American comic books published by Marvel Comics and is a founding member of the X-Men. Created by writer Stan Lee and artist Jack Kirby, the character first appeared in The X-Men #1 (September 1963).

Iceman is a member of a subspecies of humans known as mutants, who are born with superhuman abilities. He 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. Iceman often makes ice slides which form rapidly beneath and behind his feet, moving him along the slick surface at high speeds. He is also able to form exceedingly complicated structures within relative short time, such as miniature cities.
