Anthony was a henchman of the Scarecrow in his first criminal caper.
Anthony, along with Nigel, assisted the Scarecrow in his campaign against Dr. Long and Gotham State University. Although not especially intelligent, he was sharper than Nigel and didn't annoy the Scarecrow as much.
When Batman boarded the Scarecrow's blimp in its flight from the university, Scarecrow ordered Anthony to climb out onto the blimp's surface to shoot him. Batman disarmed him and in the fight that followed both of them tumbled off the blimp together. Batman stopped his fall with his grapple, while Anthony fell to the street below, but his fall was stopped by a door canopy.
