Harley Quinn steals cosplayers' hearts at Comic-Con 2016

One of the most popular versions of Harley Quinn we've seen here at Comic-Con in San Diego is the villian played by Margot Robbie in the upcoming "Suicide Squad."

This cosplayer went with the original jester outfit Harley Quinn wore in her first appearance on "Batman: The Animated Series."

Harley was created by Paul Dini and Bruce Timm for a small role on "Batman: The Animated Series." Harley's surprising popularity with viewers resulted in the creation of her backstory, and her permanent place in the DC universe.

Dr. Quinzel was originally an Arkham Asylum psychiatrist who became fascinated with the Joker. Her life changed dramatically when she fell in love with her patient and abandoned her career to become the Joker's infamous sidekick, Harley Quinn.

DC Comics describes Harley Quinn as the "poster girl for chaos' terrifying allure."

Because any popular character will be genderbent.

He even made a male version of the shirt! Wonder if there's a Missus Jay around.

Actress Margot Robbie admitted to The New York Times that wearing Harley Quinn's skin-tight outfits sometimes made her feel "self-conscious."

Cosplayers can't get enough of Suicide Squad Harley.
