Best Harley Quinn Comics (Updated: September 2025)

Unlike most DC characters who began as comic book creations, Harley Quinn first appeared in the 1992 animated episode of Batman, “Joker’s Favor.” Originally meant for just one appearance as a contrast to the Joker, she quickly became popular with both the show’s creators and viewers, leading to her becoming a regular character. Two years later, her backstory was explored in the comic book *The Batman Adventures: Mad Love*, which revealed she was once Harleen Quinzel, a psychologist who fell in love with the Joker while interning at Arkham Asylum. After that, she became an increasingly important character within the broader DC universe.
