Copperhead

History

Nothing is known about the life of the criminal known as Copperhead before he first appeared 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 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 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.

Copperhead was killed by Manhunter and has been identified as one of the deceased entombed below the Hall of Justice.

A new Copperhead has surfaced as a member of the Terror Titans. 
 
Blackest Night

In Blackest Night, Copperhead was kept in the Hall of Justice's morgue, but has been ressurected by the Black Lantern Corps. He is now helping the Black Lantern Justice League members along with Dr. Light, Alexander Luther of Earth-3, Maxwell Lord and many other dead Justice League villains.
