All April long, we'll be highlighting the wonderful world of comics, from interviews with creators and a look at the way the industry works to deep dives with our favorite characters, storylines and controversies. Stay tuned for more throughout the month, and let us know what you think in the comments or on Twitter @blastr!

Dateline: September of 1992. A striking red and black jester bursts from a cake on Batman: The Animated Series and a twisted star is born. Twenty-four years later, she's one of the most recognized faces in The Dark Knight's rogues gallery, a nefarious group that largely consists of characters who had a 50-year head start on our gregarious gal, Harley. What is it about this one-time henchgirl that's given her so much life beyond her humble cartoon origins with loyal fans in and out of the comics community?

Every time the character has crossed into a new medium, be it a starring role on the short-lived Bird's of Prey TV series, a memorable turn in the wildly popular Arkham games, or the mountains of merchandise spinning out of DC's Bombshells line, she's seen an exponential growth in her notoriety. With Margot Robbie bringing us Harley's Debbie Harry-inspired live-action film debut in David Ayer's Suicide Squad this summer, it's likely we'll see another leap in the sidekick-turned-antihero's pop culture presence.

Here's a list of 18 significant versions of Harley we've seen across comics, television, video games and more. Run down the rowdy roster of hellacious Harley Quinns and tell us which ones you love best.
