Young and impressionable, Dr. Harleen Quinzel was a psychiatrist assigned to Arkham Asylum. While attempting to heal the Joker’s mind, Quinzel found herself captivated and fell in love with him, proceeding to help him in his escapes from Arkham and assisting her puddin as his henchwoman; Harley Quinn.
In the alternate future Harley assisted The Joker during the climatic battle between the Justice League and the Society. She was killed after she used her body to shield The Joker from an explosion caused by a combination of Black Adam, The Flash, and Green Lantern's powers. She appears to have killed or assisted in killing Robin sometime prior to this, as she is seen wearing his tattered cape.

- Despite having a comical personality, Harley Quinn has the stance of a flirty female character.
- Part of Harley's psychosis is that she sees violence as it is depicted in comedy cartoons, as such she doesn't see the blood or traumatic injuries that her "pranks" inflict. Instead they are visually translated into cartoonish images that only she can see.
- Harley has two hyenas that she keeps as pets; Bud and Lou (named after the comedic duo Bud Abbott and Lou Costello). Originally the Joker's pets, the villain never really cared for the two and they were quickly adopted by Harley.
- After discovering her existence during a conversation with ex-Suicide Squad member Jewelee, Harley occasionally makes prank calls to Oracle late at night.
- Harley is openly bisexual and a swinger. A proponent of free-love, sexual experimentation, sexual play and casual liaisons, Harley has no qualms with engaging in sexual relationships with men or women for fun but will not engage in such activities if she feels a relationship will be destroyed by it. In addition to the Joker, one of her more notable lovers is her close friend, Poison Ivy, with whom she shares an open relationship/friends-with-benefits arrangement.
