|~ Copperhead to Batman|
Before appearing in Gotham City, Copperhead was already famous throughout South America for her skills as an escape artist. Having successfully broke out of 14 different Prisons. She also has tattoos that suggest a connection to a Central American gang.
The Eight Assassins
Copperhead is one of the eight assassins hired by Black Mask (Joker) to eliminate Batman. While Batman uses the memory card of the Drone to identify the assassins on the Batcomputer, Copperhead is seen in the GCPD being interrogated by a cop, she kills the cop when she escaped and got an evelope to kill Batman. She is seen in Sionis Industries after Batman arrives. While searching for Black Mask in the Steel Mill, Batman encounters a dead Joker Thug inside the Elevator Shaft. After scanning his body, Batman discovered he was killed by a poison in his system.
While interrogating Black Mask, Copperhead ambushes and attacks Batman, managing to poison him with her deadly claws. Black Mask escapes during this and Copperhead escapes too, with Batman heading to ground level after telling Alfred Pennyworth to drop an antidote. While on his way, Batman had hallucinations of Alfred saying his a dishonor to the Wayne family and both the Bank Manager and Commissioner Loeb complaining that Batman didn't save them.
Batman enters the ground level and then finally encounters Copperhead, and due to the nerutoxin affecting his mind, various copies of herself are created in Batman's mind and attack him. When Batman fights off waves of Copperhead's clones, Batman gained the antidote and used it, curing him. Copperhead makes a final attempt to kill him but is taken down and imprisoned in a Metal Crate. She tells Batman that Joker and other assassins are at a meeting, while pleading to be released, Batman ignores her and locks her up. He then calls the Police to capture her, imprisoning her in Blackgate Prison.
