Plot Synopsis

Harley Quinn has finally broken things off once and for all with the Joker and attempts to make it on her own as the criminal Queenpin of Gotham City in this half-hour adult animated action-comedy series. The series features Harley Quinn, Poison Ivy, and a whole cast of heroes and villains, old and new, from the DC Universe. On Friday, November 29, 2019 at 3:01am ET/12:01am PT, DC Universe released the first episode of HARLEY QUINN, with additional episodes scheduled to debut subsequent Fridays.

DC Universe premiered the sophomore season of HARLEY QUINN on Friday, April 3, 2020. Harley Quinn has taken down the Joker and Gotham City is finally hers for the taking...whatever's left of it that is. Gotham has become a desolate wasteland, left in ruins, following the huge earthquake caused by the collapse of Joker's tower. Harley's celebration in this newly created chaos is cut short when Penguin, Bane, Mr. Freeze, The Riddler, and Two-Face join forces to restore order in the criminal underworld. In the season opener, "New Gotham," Gotham is declared no longer part of the United States, and the newly formed Injustice League tries to seize control of the city away from Harley. A new episode debuts each subsequent Friday.

For its third season, HARLEY QUINN moved to HBO Max, where it debuted on Thursday, July 28, 2022. Wrapping up their "Eat. Bang! Kill. Tour," Harley Quinn and Poison Ivy return to Gotham as the new power couple of DC villainy. Along with their ragtag crew -- King Shark, Clayface, Frank the Plant -- "Harlivy" strives to become the best version of themselves while also working towards Ivy's long desired plan of transforming Gotham into an Eden paradise. Three Season 3 episodes of HARLEY QUINN dropped on Thursday, July 28, 2022, with a new installment debuting each Thursday through September 15.
