He was portrayed by Juan Riedinger.
A.J. and fellow thug Bruno Mannheim ambushed Chloe Sullivan outside a gala event. Lois Lane heard her screams and went to her aid; she whacks Bruno with her stiletto heels before kicking A.J. down. However, Bruno escapes with Chloe's handbag and car, which contains her laptop. A beaten A.J. sarcastically asked Lois if she's some sort of superhero, to which Lois replies she's Stiletto.
A.J. was arrested, but was released on bail and returned to the Ace of Clubs which Bruno recently took over. The new bartender Jimmy Olsen arrived late to work where Bruno and A.J. noticed he had his camera and took it away from him, admiring it before recognizing Chloe and Stiletto in his pictures. A.J. then shoved Jimmy onto the balcony where Bruno beats him, demanding to know where Stiletto is, before hitting him with the camera so that it falls over the balcony rail into the street. Bruno then told A.J. to find out who Chloe was while Ricky would unlock her laptop.
At the Talon, Chloe was coming downstairs into the basement when A.J. attacked her. He held a knife on her demanded she tell him who Stiletto was. She manages to break free, but A.J. catches up to her and pinned her against a wall with a knife. As he was about to slit her throat, Doomsday emerged from the basement of the Talon drags him away and brutally killed him. After Doomsday finished him off, Chloe bagged up A.J.'s remains in two large garbage bags and threw them into a dumpster at the back of the Talon.
A.j.'s remains were later found by the police in the dumpster and Clark Kent realized that Davis Bloome was still alive.
