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."
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.
