Irving was a henchman of Cameron Kaiser.
Facing a financial disaster, Kaiser decided to cash in insurance money by having the Joker wreck his brand new casino. He already redecorated it—from Camelot to Joker's Wild—to infuriate the Clown Prince of Crime; the only thing he needed now was to spring the Joker out of Arkham.
Irving infiltrated the Asylum as a guard in order to let Joker escape—though he had to do so without the Joker noticing it. He played it dumb, taking a feigning Joker to the sick bay, but "accidentally" leaving the doors open.
With the Joker on the loose, Irving returned to the casino. He caught Batman sneaking around in Kaiser's offices, but after a short fight the Dark Knight left Irving fighting a smoke pellet.
