Paul Dini & Bruce Timm (2019)

Following an unsuccessful yacht robbery, Harley Quinn is sent to Arkham Asylum; though she firmly believes that her boss and lover the Joker will break her out. A year later, her best friend, Poison Ivy, gets her out during a prison break and tries to convince her that he does not love her. Despite Ivy’s support, Harley’s attempt to break up with the Joker fails after he sweet-talks her into staying with him. The Riddler, who also escaped Arkham, provokes the Joker into sending Harley to kill him. The Riddler captures her and Batman before giving the Joker the choice to save one while the other dies. When Joker ultimately chooses Batman, Harley finally realizes she never meant anything to him. After learning Ivy and Riddler devised the death trap to drive that point home and she was never really in any danger, Harley undergoes a costume change and officially breaks up with the Joker and declares her intention to make a name for herself in the criminal underworld.

The series follows Harley Quinn’s adventures after she breaks up with the Joker and her attempt to join the Legion of Doom, forming her own crew consisting of Poison Ivy, Clayface, Doctor Psycho, King Shark, and Sy Borgman. When she finally achieves this goal however, she inadvertently distances herself from her newfound friends and continues to face problems from the Joker, who refuses to accept the idea of Harley becoming a supervillain on her own.
