Warner Bros' upcoming DC digital streaming service has ordered a Harley Quinn animated TV series, and cinematic Harley Quinn Margot Robbie is expected to be pursued to voice the lead character. The new service has already ordered a live-action Titans series, and an animated Young Justice revival, both set to go live in 2018.

Harley Quinn first appeared in an episode of Batman: The Animated Series as a throwaway character and immediately captured the imagination of fans. The character was given her own origin story in the 1994 graphic novel The Batman Adventures: Mad Love, which introduced Quinn's alter ego Harleen Quinzel, an Arkham Asylum psychologist who falls in love with the Joker and becomes his partner in crime. Quinn made the leap to the big screen in 2016's Suicide Squad, and is set to next appear in the sequel Suicide Squad 2. Quinn is also expected to co-star in a Joker and Harley Quinn film and the all-female DC team-up Gotham City Sirens, though any and all DC-related movie plans have to be considered shaky after the less-than-stellar box office performance of Justice League.

Harley Quinn's enduring popularity among die-hard comic book fans, and her larger profile in pop culture thanks to Robbie's performance in Suicide Squad, has prompted DC's digital streaming service to order an animated series revolving around the character. As reported by Deadline, 26 episodes of the half-hour adult animated action-comedy series - emphasis on "adult" - have been ordered, and Robbie is Warner Bros' top choice to voice Quinn. Warner Bros. also released art for the series:

Deadline reports Harley Quinn will also feature Poison Ivy and other DC characters (making it something of an animated Gotham City Sirens), and will focus on Quinn finally dumping the Joker and trying to establish her own Gotham City criminal empire. Mary Tyler Moore meets Harley Quinn will be written and executive produced by Justin Halpern, Patrick Schumacker and Dean Lorey, whose DC-adjacent Powerless series failed to gain traction at NBC.

Very early concept art for Harley Quinn was shared by Deadline, and shows a design of Quinn in line with her 2014-era comic book look. The character has changed appearances multiple times over the years, and which version of Quinn to use will be a major decision for the creative team behind the animated series. How crazy and evil to make Quinn will also have to be worked out, though if she's trying to create her own criminal empire, one assumes she will be fairly evil and plenty crazy. Another big question is how the series will address the Joker, if he will be a major player beyond the early set-up where Quinn reportedly dumps him.

If Robbie can't be secured to play the lead, Harley Quinn producers could turn to Melissa Rauch who played the character in last summer's animated Batman & Harley Quinn team-up that premiered during SDCC.
