Harleen Quinzel as Harlequin
Another prime example of an animated character’s popularity forcing them back into the official comic book canon is Harlequin. Harleen Quinzel was a psychiatrist at Arkham Asylum who was assigned to the Joker. Not only did she fail to reform him, but her deep probing of his mind drove HER insane and she fell madly in love with him.
She was initially written as a desperate, clingy stalker used exclusively for comic relief. However, in recent continuity, she has grudgingly recognized that the Joker never loved her, and has become a thorn in Batman’s side in her own right.
