Harley Quinn Definitively Proves She's a Hero With One Sacrifice
For years, Harley Quinn has worked as the villainess by Joker's side ever since her introduction to DC Comics, but over time, she's finally become a hero in her own right. Harley was a psychiatrist at Arkham Asylum but she was swayed towards the allure of evil by DC's most evil Gotham resident. From then on, she embarked on a path of villainy as Joker's sidekick and romantic partner.
