Biography
Bobby Liebowitz was a white male with shaggy brownish-blonde hair. He was a resident of Gotham City and went to high school with Harleen Quinzel. Bobby and Harley were supposed to go to the senior prom together, but Bobby dumped Harley in favor of another girl, which broke her heart.

Many years later, Harley caught sight of Bobby while working a case with Batman and Nightwing. Completely distracted from the more urgent matter at hand, Harley took off running after Bobby, who fled the scene. They chased each other through the streets of Gotham, nearly being struck by oncoming traffic. She then pursued him up the side of a building and across several rooftops. She finally caught up with him in an alley and beat the snot out of him, finally exacting her revenge for the pain he caused her so many years ago.
