Gotham's Blackgate Penitentiary once had a Gallows Tree from which 313 criminals with death sentences were hanged. The wood from that tree was whittled by an inmate into the puppet Scarface, and that inmate was murdered by Arnold Wesker, a man who soon fell under Scarface's influence. While most believe that Scarface is simply a tool through which Wesker, as the criminal mastermind, the Ventriloquist, acts out a dark side to his personality, Wesker himself believes that Scarface is possessed by the souls of who died beneath the gallows Tree, and the puppet actually motivates him to commit the duo's many crimes.
Arnold Wesker is a ventriloquist with multiple personalities. His puppet is a gangster named Scarface. Under the puppet's psychological influence, Wesker is a dangerous and ruthless criminal and crime boss. It has been implied that the Ventriloquist suffers from multiple personality disorder. Wesker was originally a timid orphan whose deep repression erupted into a barroom brawl, resulting in him being sent to Blackgate Prison. There he encountered the ventriloquist dummy Scarface and promptly murdered the man who'd carved the dummy. The two are now inseparable, directing a series of criminal activities. While most believe that Scarface is a tool by Wesker is simply acting out a dark side to his personality, the Ventriloquist sees himself as a reluctant lackey who is forced to do Scarface's bidding.
