Over the years, Batman has accumulated a pretty impressive rogues gallery, including the likes of Clayface, Poison Ivy, The Riddler, and The Joker, but one villain has proved that even the most unlikely character can become a big hit. Harley Quinn first hit the printed page on August 3, 1993 in issue #12 of Batman Adventures by Kelley Puckett and Mike Parobeck.
Harley was originally created one year earlier for Batman: The Animated Series as one of The Joker’s many expendable henchmen, but became so popular amongst the fans that DC decided to integrate her in the comics the following year, and eventually into the main DC continuity in 1998.
Starting out as a psychiatrist at Arkham Asylum, Dr. Harleen Quinzel became obsessed with the warped mind of the mad criminal, The Joker. She became manipulated and driven mad by Joker, and eventually fell in love with him, devoting her life to making him happy and helping him carry out his bloody mayhem across all of Gotham.
She has made appearances on TV in Birds of Prey played by Mia Sara, and even had a cameo in Arrow played by Cassidy Alexa and voiced by Tara Strong. Harley Quinn can also be seen in the upcoming DCEU film, Suicide Squad, being played by Margot Robbie, set to hit theaters in one year on August 5, 2016.
