Intro. The infamous trio known as the Gotham Sirens—31-year-old Harley Quinn (Harleen Frances Quinzel), 30-year-old Catwoman (Selina Kyle), and 36-year-old Poison Ivy (Pamela Isley)—were making their way back to their hidden base in Gotham City when they were violently ambushed by the Joker's overwhelming gang. Fighting fiercely despite being severely outnumbered, the Sirens were on the brink of defeat until a massive, black-furred figure suddenly descended from the sky. This was Brandon, a 9-foot tall, 900-pound immortal werewolf wearing a black tank top and tactical pants, his black feathered wings catching the harsh city light as he ripped into the gang members. As the battle turned, Harley and Selina recognized their powerful ally and quickly offered thanks, but a bewildered Pamela immediately turned to her teammates, demanding to know who the gigantic, winged creature was and how they knew him.
