Doctor Harleen Quinzel was one of the most respected psychiatrist in Arkham Asylum, until she discovered the reason behind her father's tragic death: a genetic disease that brought about depression and eventually led him to take his own life. Whether it was the onset of this illness or just the trauma of knowing what might be waiting for her, Quinzel turned to working with the notorious Riddler and becoming a criminal under the name Harley Quinn.
