Copperhead's special snake suit was upgraded by Darkseid's forces, and all of Copperhead's super-abilities stem directly from it. The snake-suit has the following characteristics:
Burglary * Safe Cracking
Herpatology * Carousing * Poker
The Secret Society of Super-Villains
Nothing is known about the life of the master criminal called Copperhead before he first appeared on the scene in Gotham City, confounding the police with a series of rapid-fire thefts. Using his unique uniform, the serpentine king of crime stole a variety of precious gems and artifacts before he was finally apprehended through the combined efforts of Batman, Batgirl, and Wonder Woman.
After spending several years in prison, Copperhead finally managed to escape with the aid of an old colleague who smuggled him a new and improved snake-suit. Once outside the prison walls, Copperhead learned that his new costume had been provided by the fledgling Secret Society of Super-Villains, who invited him to become one of their founding members. Accepting the invitation, Copperhead served on and off with the ever-changing organization until it apparently dissolved.
Although Copperhead was returned to prison several times during his association with the Secret Society, his whereabouts at the time of this writing are unknown.
