Harleen Quinzel also known as Harley Quinn, is a former psychiatrist and the on-off girlfriend to The Joker.
Harleen Quinzel worked as a psychiatrist at Arkham Asylum. When The Joker was imprisoned there by the masked vigilante Batman, she took a particular interest in him, regularly visiting and speaking with him. Harleen was gradually psychologically sabotaged and manipulated by the psychopath and eventually falling in love with him, and the Joker got her to do him a favor, which was giving him a machine gun. Shortly thereafter, Joker's goons broke into the asylum and and successfully broke their boss out. Before leaving however, Joker sadistically subjected Harleen to shock therapy, but she took the pain.
Harleen later chased the Joker down and managed to get him to stop his car. She nearly killed him with a gun, even shooting a man who approached them. The Joker took the gun and taunted her. Harleen wanted to come with him and he took her to Ace Chemicals. While there, she was told to say the oath and was asked of she would die for him. She responded in the affirmative, and allowed herself to fall in the vat of chemicals that created the Joker years back. The Joker considered leaving her to die, but promptly changed his mind and jumped in after her, pulling her up to the vat's surface. He then kissed her and Harleen awakened with the same frontotemporal dementia that her lover received via exposure to the chemicals and oxygen deprivation as the Joker broke down into maniacal laughter.
From that point on, the Joker dubbed her "Harley Quinn", giving her a red-and-black Harlequinn costume, and the duo of psychopathic lovers would go on a number of crime sprees in Gotham City together, which would often result in the duo coming into conflict with Batman, becoming (as Amanda Waller would later claim) the king and queen of the Gotham City Underworld.
The Joker, with Harley's help, managed to kill Batman's partner, Robin. To add injury to Batman's loss in hopes of driving their mutual adversary insane, Joker spray-painted " HAHAHA JOKE'S ON YOU BATMAN" in yellow on the Robin suit. A devastated Batman would later place the damaged and vandalized suit in an exhibit in the Batcave.
