Harley Quinn is the Joker's right-hand woman. A deadly combination of intelligence, beauty, athleticism, and psychosis, Harley has been devoted to the Joker - her "puddin"- since the early '90s.

If you're thinking of dressing as Harley this Halloween, here are some helpful character tips, costume options, and a DIY Hammer tutorial to take your Harley Quinn cosplay to the next level!

Where did she come from?

If you're looking to cosplay Harley Quinn, it's helpful to know a little bit about her origins. Like so many of the comic book characters in the DC universe, Harley has multiple origin stories. Unlike many characters, however, her first appearance was not in the pages of a comic book. Quinn first appeared in Batman: The Animated Series, as a way to add some variety to the Joker's frequent appearances. She was meant to be the animated version of a walk-on role but she was so popular with fans that she eventually became a regular facet in the series. Her popularity continued to grow to the point that she was eventually written into the comic book universe, and since then she has added live-action shows and video games to her repertoire.

Where did her name come from?

Quinn's origin begins with the story of Dr. Harleen Quinzel, a psychiatrist at Arkham Asylum responsible for treating The Joker. Eventually, she fell in love with him and helped him escape the asylum! The Joker then dubbed her Harley Quinn, and the rest, as they say, is history.
