Harley Quinn is a deranged supervillain suffering from hybristophilia.
She helped him escape and took on her own criminal alter ego as Harley Quinn, a nickname she had throughout her life that the Joker was fond of. Quinn is almost just as violent and predictable as Joker himself, and her only goal is to earn his approval.
Because of his cruel and abusive nature, she is in some ways just another one of his victims. However, she is still incredibly dangerous.
