Hyena was a criminal who operated in Gotham City in the 1980s, constantly dealing with Bruce Wayne Jr. as Batman. She admired batman's greatest enemies and studied all their best schemes.

During one chase six bystanders were sent to hospital. Everyone assumed it was the fault of Batman, but it was in fact the fault of Gotham Police. Batman manged to track down Hyena, and defeated her henchmen in ten seconds. When Hyena attacked Batman thinking she could overcome him, she was easily tossed against the wall unconscious, and then bound for the police to find.
