Jeremiah Arkham was present when Hugo Strange unveiled D.A.V.E. at Arkham Asylum. Arkham only had a brief appearance so it is unknown if he was one of Gotham's corrupted officials under the employee of Black Mask.
In the not to distance future Jeremiah Arkham became the second Black Mask. He took control of Gotham's underworld. However, because corruption had already been stopped after the original Black Mask was defeated Arkham did not have the same resources as Roman Sionis did. He was quickly defeated and placed in his own asylum.
