20 Harlequinesque Facts About Harley Quinn

On September 11th (yikes), 1992 (okay, whew), Harley Quinn made her debut on Batman: The Animated Series just as a walk-on foil for the Joker to break up the sausage fest in his gang. Creator Paul Dini never imagined that the character would not only show up in other episodes, but be fully immersed in the DC Universe due to popular demand. Over the past 20 years, Harley Quinn went from being the abused member of Joker’s gang to having her sense of agency to having multiple comic book series, her own movie, and her own cartoon show.

Whether you like her or don’t, Harley Quinn’s popularity isn’t going anywhere.
