Speaking of the Joker, Harley Quinn is better known as the sidekick to that iconic villain. She was invented by the creators of Batman: The Animated Series, and has since become a fan-favorite antihero in comics and films.
Harley Quinn’s origin story is well known in the comics but has yet to be clearly detailed in the cinematic world. Elements of her backstory are seen in The Suicide Squad and in 2020’s Birds of Prey. She begins as psychiatrist Harleen Frances Quinzel, treating patients at Arkham asylum. While on assignment, she falls for the Joker’s persuasive personality and becomes his criminal sidekick.
One might argue Joker simply unlocked her true anti-establishment nature, helping her realize her self-actualize. Either way, she eventually breaks free of Mr. J in the new movie, and has become a symbol for women everywhere who choose to say “fuck the system” and embrace their free spirits.
You can stream Birds of Prey, or the Fantabulous Emancipation of One Harley Quinn on HBO Max.
