Harley Quinn is the unpredictable bubbly and violent former Arkham Asylum therapist. She's stuck in a codependent abusive relationship with Joker, and is his henchmen. Sometimes she dates Poison Ivy. She's one of batman's most dangerous villains, but plays dumb even though she is intelligent. Sometimes she works for the suicide squad or cooperates with batman, but she mostly does terrible things. Her hyenas, her precious babies Bud and Lou are sick and need treatment.
