-- Harley Quinn src

Harleen Quinzel, better known as Harley Quinn, was the Joker's partner-in-crime until the madman was killed by Superman. From that day forth, she worked to oppose Superman and became a crime fighter-in-training.


Harleen Quinzel was an intelligent psychiatrist at Arkham Asylum before she was seduced into madness by the Joker, her patient at the time. Becoming "Harley Quinn", the two clowns terrorized Gotham City and found themselves constantly in combat with its protector - Batman.

About four years prior to the Joker's death, Harley became pregnant with the Joker's child and went into hiding for a year. Having a girl, she named her Lucy Quinzel and left the baby with her sister before returning to Gotham, only to discover the Joker hadn't even noticed her absence.[1]

Years later, the Joker set his sights on terrorizing Superman and, with Harley by his side, he used Scarecrow's Fear Toxin to trick the hero into killing Lois Lane and his unborn child. Distraught over what he'd done, Superman killed the Joker in retaliation and began establishing a new fascist Regime.[2] [3]

Year One

Superman hired Lobo to capture Harley, but Harley eluded him twice, and finally led him to the Arrowcave where she, Black Canary, Green Arrow, and Speedy defeated Lobo. Harley used her physiatric ability to determine the cause of Lobo's aggression. She figured that Darkseid belittled Lobo, and suggested that Lobo go back and defeat Darkseid, to which Lobo agreed.[4]

Injustice: Year Five

Disillusioned with working so closely with the Insurgency, Harley "went rogue", being a vigilante without a team but still considering the Insurgency her allies. She spent her time investigating a Joker-memorial street gang lead by Jason Bard before Superman discovered the gang's existence and slaughtered all 200 of them.[5]

Distraught over the massacre, Harley decided to give up her alias altogether and, after being her own therapist, dyed her hair back to blonde and returned to being "Harleen Quinzel". Not too long after, though, Harleen found herself in the middle of another Joker-themed anti-Regime gang and, deciding they needed a competent leader so they wouldn't be killed like the last group, returned to being Harley Quinn to lead them.[6]

On the night that Batman and Lex Luthor attempted to teleport an alternate reality Justice League to fight the Regime with them, Harley and her gang were requested by Batman to act as a distraction for the Regime, targeting a green pill factory. The attack caught the attention of the new Regime recruit Man-Bat, but Harley successfully defeated him while on half a green pill.[7] Batman and Luthor's mission, too, was a success, and several alternate reality heroes (and a villain) were transported to Earth.

Injustice: Gods Among Us

Harley Quinn, now going by the name Harleen, confronts the alternate Joker in Gotham City, believing him to be an impostor, as 'her' Joker was killed by Superman after destroying Metropolis. After a fight between the two, Harleen realizes from the Joker's fighting style that he is the real Joker and is overjoyed to see him.

Harleen takes the Joker to the abandoned Arkham Asylum, hideout of the Joker Clan, a criminal force assembled in the Joker's memory. The Joker is quick to assume control of the Clan, using one of the durability enhancing pills given by Superman to his flunkies on himself. Shortly after this, Regime soldiers lead by Hawkgirl and Nightwing break into the hideout and attack the Clan. As the Joker fights off Hawkgirl and Nightwing, Harleen sends an S.O.S. to Insurgency Batman via a communication device given to her by the Insurgency. The Insurgency forces, consisting of the alternate Wonder Woman, Green Lantern, and Green Arrow, Aquaman, and the native Batman, soon arrive and drive back the Regime. Batman orders Harleen and her men to lay low for the time being and takes the Joker into custody, believing him to be too dangerous to be let loose.

When the Insurgency begins their bid to save the displaced Batman from being executed, Harleen receives orders from the Insurgency Batman to have the Joker Clan occupy as much law-enforcement as they can while they infiltrate Stryker's Island. Harleen complies, but goes against Insurgency Batman's orders and releases the Joker from his cell, although she fears that Batman may be angry with her for doing it.

Harleen and the Joker hijack a Regime vehicle and confront the Insurgency Lex Luthor in Metropolis as he heads to aid the Insurgency against the Regime. The Joker orders Harleen to take down Luthor and take his suit, but she ultimately fails. Fed up with Harleen, the Joker fires her and tries to kill her. However, Luthor intervenes and takes down the Joker in a fight. Enraged by his betrayal, Harleen prepares to kill the Joker with his own knife, but is ultimately convinced by Luthor to let him go, saying she's outgrown him.

In the epilogue, Harleen is shown escorting the Joker at gunpoint to the portal back to his dimension.

Harley Quinn Injustice GAU Epilogue 0001

"The defeat of Superman filled Harley with confidence. She knew what she was capable of and knew what she wanted. She traveled to the visitors' Earth and freed the Joker from prison. Returning to her world, they married in a ceremony that set Gotham ablaze.

At the reception, the cake-cutting ceremony took a gruesome turn. As her new husband playfully mashed her face into the cake, years of abuse took its toll. Something in Harley snapped. She used the ceremonial knife to slash Joker's throat.

Still wearing her wedding gown, Harley now resides permanently in Arkham Asylum."

Main article: Injustice 2 Vol 1

After the fall of Superman's regime, Harley was invited by Batman to join him in his reconstruction effort to fix all the worldwide damage Superman had caused. Of course, Harley accepted but, not long after, she was kidnapped by Amanda Waller and once again forced to join the Suicide Squad. However, not long after that, Waller was murdered by a Batman impostor who commandeered the Suicide Squad for the League of Assassins.

Forced to do the League's bidding or risk having her head explode, Harley and the Squad were sent to distract a group of heroes by crashing Green Arrow and Black Canary's wedding. The distraction proved successful, and the League managed to kidnap some of the heroes' children - Harley's estranged daughter Lucy as well. Back at the League's secret base in the Amazon Rainforest, Harley was forced to reveal her true parentage to her daughter before Quinn and the children attempted to make an escape. Thanks to Batman and the children's parents, the rescue was a success, though at the expense of the League of Assassins' endangered animal sanctuary.

Harley Quinn Injustice 2 Epilogue

"I still can't believe it. Me. Bringing down Brainiac. Who knew? Still, Bats surprised me, offerin' me a spot in the Justice League. Not totally sure he ain't crazy, but who says no to that guy? Y'know, being good feels good. But every now and again, every once in a while, I get this irresistible urge to go out and bash some heads!

Hopefully being good will stick long term. 'Til I'm sure, my kid Lucy's still gonna known me as her crazy Aunt Harleen. Maybe someday I can giver her the real scoop."



  • Mental Illness: Dr. Quinzel was driven insane by the Joker. Even after breaking free of his control, she still has homicidal impulses that she can usually overcome.[8]
