Harley Quinn is a DC Comics villain that actually first appeared on a Batman cartoon before being incorporated into the printed stories. Harleen Frances Quinzel, M.D. was a psychiatrist at Arkham Asylum, who falls in love with the Joker and becomes his accomplice and on-again, off-again sidekick, following a Harlequin theme to fit how her “Puddin'” is a court jester. Harley has been voiced by Arleen Sorkin, Hynden Walch and Tara Strong in cartoons and video games, and portrayed by Mia Sara in the short-lived Birds of Prey series and Margot Robbie in the 2016 film Suicide Squad.
