Andrew Carter

Andrew Carter is a hardened criminal suffering from paranoid delusions and a murderer.

Batman: Arkham Origins
Andrew Carter had an extensive criminal record, and had been released from Blackgate Prison in November, with his having to undergo court-mandated therapy sessions. By Christmas, however, Carter had stopped going to the therapy sessions, and sought to join Bane's gang. After presumably being supplied with Venom, he underwent an initiation, where he proceeded to throw an air conditioner fan at an unsuspecting victim, who had presumably uncovered sensitive info about Bane's plans that necessitated his death. Upon completing the murder, Carter then was ordered to wait for Bane's arrival before he is to be dispatched on his mission. However, Batman, having deduced Carter's role in the murder as well as his instability, arrived and knocked out the unit, and interrogated Carter regarding what Bane had planned for Carter. Carter, however, refused to talk, resulting in Batman knocking him out and leaving him to be arrested by the GCPD.
