Stephanie "Yo, Gully! Remember me? Maybe you'd like another try at killing me?
Gully: Actually...I'd love one.
The leader of a gang working with The Cluemaster, who kidnapped Stephanie in Robin #15 with Arthur's consent. Tim rescued Stephanie, and later when they went after Gully, he tried to shoot Stephanie, but Tim jumped in front of her (he was only a little hurt as a result, thanks to his Kevlar costume) and Stephanie knocked Gully out by hitting him in the head with a diamond.
