Captain Cold

a former villian from the DC Comics.

Raised by an abusive father, Len Snart sought to start a criminal career following the death of his grandfather. At first, he attempted simple thievery with a band of thugs. After this failed to produce satisfactory results, he went solo. During a botched robbery of a cyclotron, Snart's gun was altered by the cyclotron's radiation, allowing it fire beams of pure cold, and from time to time, cast illusions. Putting togther a blue and white parka, Len became Captain Cold, one of the Flash's deadlist enemies. He is currently the leader of the Rogue's Gallery. But in the New 52, after the Crime Syndicate was defeated, Cold stopped his life of crime and became a member of the Justice League along with  Lex Luthor.
