As many know, Harley Quinn will go down as a fan favorite of DC’s, having appeared on the big screen before many other iconic characters, even Wonder Woman. Since she has been in fans’ hearts for so long, people usually assume that she has been in comics for even longer, however, Harley Quinn actually made her debut in “The Joker’s Favor”, an episode of the Emmy winning cartoon, Batman: The Animated Series. That’s right, she was a cartoon before she was a comic. In fact, Harley Quinn was originally just supposed to be an add in for that particular episode, but the immense response to her personality made her develop into one of Batman’s main villains in the series.
As previously mentioned, Quinn became a main character later on in the show’s run. So, originally, she was just created for the show, and that was supposed to be it. However, a year after her first appearance in the show, she made her comic debut in Batman Adventures #12.
Today, Harley Quinn was a main character in not only the Suicide Squad live action film, but also stars in the upcoming Birds of Prey and the Fantabulous Emancipation of One Harley Quinn.
