History
Jack Frost was an original member of the Liberty Legion, a group of superheroes in the Marvel Universe who fought on the homefront during World War II. His powers included the ability to form and manipulate ice from his hands–similar to Iceman.
Jack Frost was also an alias of Gregor Shapanka, before he changed his name to the much more poetic Blizzard.
