10 Best Comic Book Villains (That Had No Powers)

10. Harley Quinn

First showing up in the exceptional Batman: The Animated Series episode "Joker's Favor", Harleen Frances Quinzel was nothing more than a sidekick and punching bag to Mistah J. It would take her a while to find a place for herself in the pantheon of DC villains, but when she finally did she would become a constant thorn in the Dark Knight's side - as well as in that of the Joker's.

Her team up with her best-friend and later romantic partner, Poison Ivy, would see them pull off a string of capers that would leave Gotham's rich and privileged with highly inflated insurance policies, as the two stole anything that wasn't nailed down.

This strategy would actually end up vexing the Dark Knight, as her unpredictability always meant that he was never quite able to get a grip on her actions.

As the years passed she would be transformed into more of an anti-hero, with her face plastered on merchandise and comic books left, right and center, but there is no doubt that at her criminal peak, Harley Quinn was one hell of a villain.
