Copperhead- Arkhamverse (Batman Arkham Origins 2013)

First Appearance: Batman Arkham Origins (2013)

Copperhead was a female assassin, who was well known throughout Soth America for 14 diffrent escapes from various prisons. She is also believed to be in a gang, due to having similar tattooes to other known criminals and numerous people taking up the alias of Copperhead, both male and female.

Copperhead came to Gotham on the orders of Black Mask (the Joker), but was arrested by police and held in custody. During her interrogation, the police man was in the middle of saying that she would not be able tio escape again, but is killed by Copperhead, who gets out of her handcuffs and brakes his neck using her legs. She then obtained her contract to kill Batman. She was caught on the Penguin's drone, which Batman used to find out about the assassins and Black Mask's plot to kill him.

At some point during her task, she worked out that Black Mask was really being impersinated by someone else.

Copperhead lurks around the Sionis Steel Mill, waiting for Batman to arrive and sneaking after him in the shadows (a presence he can feel, but not identify.)  She attacks a thug in an elevator using her neurotxins and watches Batman as he realeses Roman Sionis from his trap and tries to interroagte him. She arrives and he tries to bribe her, but she says that they are empty words from a "fallen king." She poisons Batman and escapes, saying that she has killed him and soon he will realises this. Batman identifies the toxin she used from her claws so that Alfred could synthesise a cure. 

She goades and mocks Batman as he struggles to the loading bay, the toxin creating images of the dead bank manager and Gillian Loeb. He eventually meets her, who he persevies as being multiple copies of herself and after a long fight mangaes to use the cure. He eventaully over powers her and hurls her into a storage container. She begs him not to seal her inside, revealing the Joker is holding a meeting with all the assassins and tries to create a deal for him to release her, but  Batman sees through this and sarcastically thanks her, sending an annomyonous tip and leaving her for the police to pick up. She calls him a "Pendejo" through the crate as he exits the room.
