'''Harley Quinn''' ('''Dr. Harleen Frances Quinzel, MD''') is a fictional character appearing in [[American comic book]]s published by [[DC Comics]]. She was created by [[Paul Dini]] and [[Bruce Timm]] for ''[[Batman: The Animated Series]]'' as a [[henchwoman]] for the [[Joker (character)|Joker]], and debuted in its 22nd episode<!-- the article for jokers favor lists it as the 22th episode -->, "[[Joker's Favor]]", on September 11, 1992. While intended to appear in one episode, Quinn became a recurring character within the [[DC Animated Universe]] (DCAU) as the Joker's sidekick and love interest, and was adapted into [[DC Comics]]' [[Canon (fiction)|canon]] seven years later, beginning with the [[One-shot (comics)|one-shot]] ''Batman: Harley Quinn'' #1 (October 1999). Quinn's [[origin story]] features her as a former [[psychologist|psychiatrist]] at [[Gotham City]]'s [[Arkham Asylum]] who was manipulated by and fell in love with the Joker, her patient, eventually becoming his accomplice and lover. The character's alias is a [[word play|play]] on the [[stock character]] [[Harlequin]] from the 16th-century [[Theatre of Italy|Italian theater]] {{Lang|it|[[commedia dell'arte]]}}.

Following her introduction to the comics in 1999, Harley Quinn was depicted as the former [[Florence Nightingale syndrome|doctor turned sidekick and lover]] of the Joker as well as the criminal associate and best friend of [[Poison Ivy (character)|Poison Ivy]]. Later stories depicted Quinn as an independent [[supervillain]] who has left her [[Codependency|codependent]] relationship with the Joker behind, beginning with the publication of her [[ongoing series]], ''[[Harley Quinn (comic book)|Harley Quinn]]''. After years of scarce appearances in comics, Quinn returned in a leading role in 2009 with the ''[[Gotham City Sirens]]'' series, as part of an unstable alliance with Poison Ivy and [[Catwoman]]. The character's design was modernised in 2011 for DC's "[[The New 52]]" line-wide relaunch, with the character since regularly featuring as an antihero in the ''[[Suicide Squad]]'' and ''[[Birds of Prey (team)|Birds of Prey]]'' team books. Other changes included fronting her own light-hearted Harley Quinn comic book and being established in a new romantic relationship with Poison Ivy.<ref name="intoherown">{{cite web|last=Knight|first=Rosie|title=Brilliant Women of Batman: Harley Quinn Comes Into her Own|website=[[DC Comics]]|date=May 22, 2019|url=https://www.dccomics.com/blog/2019/05/22/brilliant-women-of-batman-harley-quinn-comes-into-her-own|access-date=March 4, 2021}}</ref> In 2021, DC's line-wide ''[[Infinite Frontier]]'' relaunch brought Quinn back to Gotham City and reestablished her as a [[superhero]] seeking redemption for her past actions, and now she currently acts as an [[antihero]].

Harley Quinn's abilities include expert [[gymnastic]] skills, proficiency in weapons and hand-to-hand combat, complete unpredictability, immunity to toxins, and enhanced strength, agility, and durability. Quinn often wields [[clown|clown-themed]] gag weapons, with an oversized [[mallet]] being her signature weapon. Additionally, she has a pair of pet [[hyenas]], Bud and Lou, who sometimes serve as her [[attack dog]]s.

Harley Quinn has become one of DC Comics' most popular and profitable characters. She has been featured in many of DC's comic books and adapted in various other media and merchandise. DC Comics Publisher [[Jim Lee]] considers Harley Quinn the fourth pillar of DC Comics' publishing line, behind [[Superman]], [[Batman]], and [[Wonder Woman]].

Originally voiced by [[Arleen Sorkin]] in the [[DC Animated Universe]], she has since appeared in many other DC projects voiced by actresses such as [[Tara Strong]], [[Hynden Walch]], [[Laura Bailey]], [[Jenny Slate]], [[Melissa Rauch]], [[Laura Post]], and [[Kaley Cuoco]]. Cuoco provided the character's voice in the 2019 animated series ''[[Harley Quinn (TV series)|Harley Quinn]]''. [[Mia Sara]], [[Margot Robbie]], and [[Lady Gaga]] have portrayed the character in live action media.

Dini had several names in mind while naming the character, such as [[Columbine (stock character)|Columbine]], and eventually settled on the name "Harley Quinn".<ref>{{cite web|url=https://www.angelfire.com/tv/harleyquinn/interview.html|title=Interview with Paul Dini|website=[[Angelfire]]}}</ref> Dini chose the name for the character to be in line with other Batman characters's names being [[puns]], and also because he thought "Harley was a fun name for a girl".<ref name="digitalspysecrethistory">{{cite web|last=McCabe|first=Joseph|title=Harley Quinn – her secret history, according to her creators Paul Dini and Bruce Timm|website=Digital Spy|date=November 30, 2018|url=https://www.digitalspy.com/movies/a837762/harley-quinn-bruce-timm-paul-dini-interview/|access-date=March 15, 2021}}</ref><ref name="Strangebuttrue"/> The name Harley Quinn is a [[word play|play]] on [[Harlequin]], a [[stock character]] from the [[sixteenth-century]] Italian physical comedy [[theater]] {{Lang|it|[[commedia dell'arte]]}}.<ref name="The Hollywood Reporter 2016" />

In designing the character, Timm did a "simplified supervillain version" of traditional Harlequin gear; from the {{Lang|it|commedia dell'arte}} original, he took the [[jester hat]], [[ruffled]] collar, diamond pattern, and domino mask and put them on a red-and-black [[bodysuit]], on which the diamonds were strategically placed for easier animation.<ref name="The Hollywood Reporter 2016" /><ref name="funlovingpsycho" /> Timm took Harley Quinn's red and black color scheme from the [[Golden Age of Comic Books|Golden Age]] comic book character [[Daredevil (Lev Gleason Publications)|Daredevil]].<ref name="The Hollywood Reporter 2016" /> Dini had previously made a rough design for the character, which Timm improved on.<ref name="Riesman 2020" />

After seeing Harley Quinn in the [[rough cut]] of "Joker's Favor", the producers of ''Batman: The Animated Series'', which include Dini and Timm, were impressed with the result, with Dini wanting to bring the character back for more episodes.<ref name="backissue">{{cite magazine |last=Trumbull|first=John |date=September 2017 |title=Crazy in Love: A Harley Quinn History |url=https://books.google.com/books?id=xBgxDwAAQBAJ&pg=PA67 |magazine=[[Back Issue!]] |publisher=[[TwoMorrows Publishing]] |access-date=March 21, 2021}}</ref><ref name="The Hollywood Reporter 2016" /> Timm and another producer, [[Alan Burnett]], were initially reluctant of this and thought that giving Joker a girlfriend "played more towards his comedic side" and would "humanize him too much", which contrasted their vision for Joker as a character who is "as serious a threat as possible to Batman".<ref name="backissue" /><ref name="The Hollywood Reporter 2016" /> Nevertheless, months after "Joker's Favor", Harley made a second appearance on the show in the episode "The Laughing Fish" and became the Joker's love interest.<ref name="The Hollywood Reporter 2016" /> Harley Quinn gained popularity with fans of ''The Animated Series'', with the character being featured more on the show and eventually starring in her own episodes, such as 1993's "Harley and Ivy", which introduced a friendship/romance between her and fellow supervillain [[Poison Ivy (character)|Poison Ivy]], and 1994's "Harlequinade" and "Harley's Holiday", which explored her life without the Joker.<ref>{{cite web|last=Black|first=Dorian Reyes|title=How Did Harley Quinn & Poison Ivy's Romance First Start?|website=ScreenRant|date=April 5, 2020|url=https://screenrant.com/harley-quinn-poison-ivy-romance-origin/|access-date=March 22, 2021}}</ref><ref name="gftostar"/><ref name="itistolaugh">{{cite book|last=Owens|first=Emilee|title=The Ascendance of Harley Quinn: Essays on DC's Enigmatic Villain|chapter-url=https://books.google.com/books?id=rtg5DwAAQBAJ&pg=PP1|date=October 12, 2017|publisher=McFarland|isbn=978-1-4766-2999-5|chapter="It is to laugh": The History of Harley Quinn}}</ref> Harley Quinn then became a [[recurring character]] in the [[DC Animated Universe]], appearing in ''The Animated Series'' sequel ''[[The New Batman Adventures]]'', the direct-to-video film ''[[Batman Beyond: Return of the Joker]]'', and in non-Batman animation such as ''[[Superman: The Animated Series]]'', ''[[Static Shock]]'', and ''[[Justice League (TV series)|Justice League]]''.

====Name origin====
''Mad Love'' establishes Harley Quinn's full name to be Harleen Frances Quinzel. "Harleen Frances" was taken from Sorkin's first and middle name, Arleen Frances, while "Quinzel" came from one of Dini's former [[Emerson College]] instructors, who was surnamed Quenzel.<ref name="Strangebuttrue"/>

====Introduction to mainstream DC continuity====
Harley Quinn was adapted into the mainstream [[DC Universe]] with the 1999 one-shot graphic novel ''Batman: Harley Quinn'', written by Dini and illustrated by Yvel Guichet,<ref name="batmanhqreview">{{cite web|last=Goldstein|first=Hilary|title=Batman: Harley Quinn Review|website=[[IGN]]|date=May 25, 2005|url=https://www.ign.com/articles/2005/05/25/batman-harley-quinn-review|access-date=March 21, 2021}}</ref> which put her origin in the middle of the ''[[Batman: No Man's Land]]'' story line.<ref>{{cite web|last=Howie|first=William|title=Batman: How No Man's Land Changed Harley Quinn's Origin|website=Comic Book Resources|date=December 16, 2020|url=https://www.cbr.com/batman-harley-quinn-comics-origin/|access-date=March 21, 2021}}</ref> Dini changed Harley and the Joker's relationship to be darker to match the Joker's character in the comics; in the story, the Joker attempts to kill Harley at the first opportunity. Harley's immunity to toxins and enhanced strength and agility, which were gained from a special formula created by Poison Ivy, were carried over from ''Batman: The Animated Series'', with Dini stating that they would give her a sort of "physical edge" over Batman and other heroes.<ref name="backissue" /><ref name="batmanhqreview" />

''Suicide Squad'' was canceled in April 2014 to coincide with the conclusion of the "[[Forever Evil]]" storyline.<ref>{{cite web|last=Ching|first=Albert|title=Six DC Series to End in April, Including "Superman Unchained" and "Nightwing" [UPDATED]|website=Comic Book Resources|date=January 21, 2014|url=https://www.cbr.com/six-dc-series-to-end-in-april-including-superman-unchained-and-nightwing-updated|access-date=July 11, 2021}}</ref>

====New origin====
In the seventh issue of ''Suicide Squad'', Glass revised Harley Quinn's origin story, making it reflect the Joker's origins. In the story, the Joker takes Harleen Quinzel to the [[chemical plant]] where he originated and pushes her into a vat of chemicals against her will, which bleaches her skin and drives her insane, resulting in her transformation to Harley Quinn.<ref name=autogenerated2>{{harvp|Owens|2017|p=9}}</ref> This origin was received negatively by fans, who felt that its removal of Harley Quinn's choice to become the Joker's accomplice willingly, as depicted in her previous origin stories, took out an essential part of her character.<ref name=autogenerated2 />

Harley Quinn's second ongoing series, written by husband and wife [[Jimmy Palmiotti]] and [[Amanda Conner]], with the interior art illustrated by Chad Hardin and John Timms, explored Harley Quinn leaving Gotham City and starting her own life in her hometown of Brooklyn, depicting her as a [[landlord]] in [[Coney Island]], where she shares an [[apartment building]] with a supporting cast of "[[sideshow]] freaks".<ref name="sdccharley">{{cite web|last=Phegley|first=Kiel|title=SDCC EXCLUSIVE: Conner & Palmiotti Launch "Harley Quinn" Monthly|website=Comic Book Resources|date=July 16, 2013|url=https://www.cbr.com/sdcc-exclusive-conner-palmiotti-launch-harley-quinn-monthly/|access-date=July 12, 2021}}</ref><ref name="Riesman 2020"/><ref>{{cite web|last=Opam|first=Kwame|title=The creative team behind Harley Quinn on letting an icon grow|website=The Verge|date=October 8, 2016|url=https://www.theverge.com/2016/10/8/13213252/harley-quinn-creative-team-palmiotti-conner-dc-comics-nycc-2016|access-date=July 12, 2021}}</ref><ref name="harleycbrreview">{{cite web|last=Mozzocco|first=J.

====Controversies====
The cover of the first issue of the ''New 52''{{'}}s ''Suicide Squad'' title drew controversy for its sexual depiction of Harley Quinn.<ref name="Riesman 2020"/> This also caused some fans of the character to send Adam Glass [[hate mail]] and personal threats.<ref name="glasscbrtv"/>

In September 2013, DC Comics announced an art contest entitled "Break into comics with Harley Quinn!", in which contestants were to draw Harley in one of four different suicide scenarios. This contest drew controversy not only because it was announced close to [[National Suicide Prevention Week]], but also because of the sexualized portrayal of Harley Quinn in the fourth scenario, in which the character attempts suicide while naked in her bathtub, which was highly criticised. The [[American Foundation for Suicide Prevention]], [[American Psychiatric Association]], and [[National Alliance on Mental Illness]] all responded to the controversy in an emailed group statement to the ''[[Huffington Post]]'': "We are disappointed that DC Comics has decided to host a contest looking for artists to develop ways to depict suicide attempts by one of its main villains – Harley Quinn". After seeing the reactions to the contest, DC Comics apologized, saying they should have made it clear it was a dream sequence that was not supposed to be taken seriously. In the final version, the bathtub scene was cut and replaced with Harley Quinn sitting on a rocket while flying in space.<ref>{{cite web|url=http://www.dccomics.com/blog/2013/09/05/break-into-comics-with-harley-quinn#1|title=Break into comics with Harley Quinn!|work=DC Comics|date=September 5, 2013|access-date=January 10, 2015}}</ref><ref>{{cite news|url=https://www.huffpost.com/entry/dc-comics-harley-quinn-suicide-_n_3913842|work=[[The Huffington Post]]|first=Cavan|last=Sieczkowski|title=Awful Comic Contest Asks For Drawings of Naked Woman Committing Suicide|date=September 12, 2013}}</ref><ref>{{cite web|url=http://jezebel.com/dc-comics-contest-draw-a-naked-woman-committing-suicid-1265537616|title=DC Comics Contest: Draw a Naked Woman Committing Suicide|first=Callie|last=Beusman|work=Jezebel|date=September 6, 2013 |access-date=January 10, 2015}}</ref>

===''DC Rebirth''===
In June 2016, the [[DC Rebirth]] event relaunched DC Comics' entire line of comic book titles. Both ''Harley Quinn'' as well as ''Suicide Squad'' were rebooted, with the latter starting with the one-shot issue ''Suicide Squad: Rebirth'' #1 (October 2016). Harley Quinn's ''DC Rebirth'' design included pink and blue dyed hair tips and a jacket inspired by [[Margot Robbie]]'s portrayal of the character in the 2016 film ''[[Suicide Squad (2016 film)|Suicide Squad]]'', a change established in the last issues of her ''New 52'' series.<ref>{{cite web|title=Harley Quinn's Complete Costume History in DC Comics|last = King|first = Samantha|website=Screen Rant|date=April 11, 2021|url=https://screenrant.com/harley-quinn-costume-history-new-52-comics/|access-date=January 27, 2022}}</ref><ref>{{cite web|last=Shiach|first=Kieran|title=Harley Gets A 'Cinematic' Makeover In 'Harley Quinn' #26|website=ComicsAlliance|date=March 24, 2016|url=https://comicsalliance.com/harley-quinn-cinematic-makeover/|access-date=January 27, 2022}}</ref>

Harley Quinn is skilled in using various weapons, often employing weaponized clown-themed gag items, including [[pop gun]]s, [[rubber chicken]]s, and a gun that shoots a boxing glove, as well as oversized [[pistol]]s and [[mallet]]s, the latter being her signature weapon.<ref>{{Cite comic|writer = Scott Beaty|artist = Bruce Timm|story = The Origin of Harley Quinn|title = Countdown to Final Crisis|volume = 1|issue = #10|date = February 2008|publisher = DC Comics}}</ref><ref>{{cite web|last=Nason|first=Max|title=Harley Quinn: Her 10 Best Gag Items/Weapons, Ranked|website=CBR|date=February 7, 2020|url=https://www.cbr.com/harley-quinn-best-gag-items-weapons-ranked-compared/|access-date=September 11, 2021}}</ref><ref>{{cite web|title=The Most F'd Up Moments in HARLEY QUINN's Premiere Episode, "Till Death Do Us Part"|website=[[DC Universe Infinite]]|date=December 3, 2019|url=https://www.dcuniverseinfinite.com/news/most-fd-moments-harley-quinns-premiere-episode-till-death-do-us-/|access-date=September 11, 2021|quote=When Harley attacks the yacht in the first scene, she's using a giant mallet, which has been her signature weapon since the ''New Batman Adventures'' episode "Holiday Knights".|archive-date=September 11, 2021|archive-url=https://web.archive.org/web/20210911022411/https://www.dcuniverseinfinite.com/news/most-fd-moments-harley-quinns-premiere-episode-till-death-do-us-/|url-status=dead}}</ref> Other weapons she uses include: unconventional weapons, such as a [[baseball bat]]; [[explosive weapons]] such as [[bazookas]], customized [[bombs]], and [[dynamite]]s;<ref name="bestweapons">{{cite web|last=Fida|first=Bisma|title=Harley Quinn's Bat: 10 Of Her Favorite Weapons|website=CBR|date=December 6, 2019|url=https://www.cbr.com/dc-comics-harley-quinn-bat-favorite-best-weapons/|access-date=September 11, 2021}}</ref> [[firearms]], such as [[pistols]], [[assault rifles]], and [[machine guns]];<ref name="bestweapons"/> Harley Quinn also has a pair of pet hyenas, Bud and Lou, which she can order to attack her opponents.<ref name="dcuinfiniteprofile"/>

Despite being mentally unstable and sometimes distracted, Harley is highly intelligent. Her intellect extends to her psychological, tactical and deception abilities, but she does not stand out for particular strategic or scientific skills and often remains subordinate to the Joker, who between the two is the genius and the inventor. Harleen Quinzel earned a bachelor's degree in psychology and as a former Arkham [[psychologist]], was highly qualified in [[psychoanalysis]], [[criminology]], and [[forensic psychiatry]]. While not on par with Joker, she is still an expert tactician, deceiver and escapologist, and still shows traces of her psychological experience. Harley Quinn is the only person besides the Joker to concoct Joker Venom, the Joker's signature weapon, and is shown to have reverse-engineered its formula and developed an antitoxin.<ref>{{Cite comic|writer=Dixon, Chuck & Beaty, Scott|artist =Ruhn, Andy|colorist=McCraw, Tom|letterer=Schubert, Willie|editor=Idelson, Matt & Castro, Nachie|story=Part Four: Everyone Knows This Is Nowhere|title=Joker: Last Laugh|volume=1|issue =#4|date=December 2001|publisher=DC Comics|page=22}}</ref><ref>{{Cite comic|writer=Kesel, Karl|penciller=Woods, Pete|inker=Lipka, Mark|colorist=Pantazis, Peter|letterer=Lopez, Ken|editor=Idelson, Matt & Castro, Nachie|story=Night and Day|title=Harley Quinn|volume=1|issue=#13|date=December 2001|publisher=DC Comics}}</ref> She also has an indomitable pathological will.

Just like Poison Ivy, sometimes and not as much, Harley uses her feminine charm to attract men but only to manipulate them. Unlike the Joker, she is able to simulate sanity, thus being able to pretend to be a "normal" person. In this way, she disguised herself as a security guard, a lawyer and even Poison Ivy and Batgirl.

=== Bud and Lou ===
'''Bud and Lou''' are a pair of [[spotted hyena]]s and the pets of Harley Quinn. Their names are references to the comedy duo of [[Bud Abbott]] and [[Lou Costello]]. Originally created for ''Batman: The Animated Series'' alongside Harley Quinn, Bud and Lou have since appeared in other forms of media following their debut. An alternate hyena pet, named Bruce, after Bruce Wayne, appears in the 2020 film [[Birds of Prey (2020 film)|''Birds of Prey'']].<ref>{{Cite web |last=Chrysostomou |first=George |date=February 14, 2020 |title=Harley Quinn: 10 Things You Didn't Know About Her Hyenas |url=https://www.cbr.com/dc-harley-quinn-hyenas-facts/ |access-date=April 7, 2025 |website=CBR |language=en}}</ref>

===The Joker===

| quote = "So Harley in her earlier incarnation really felt like she was the one for the Joker, that she could catch him and cure him and bring him back to humanity. But actually, in the process, she lost hers. Before she knew it she had fallen head-over-heels in love with him. I think initially he was looking to play her and get what he could out of her, and then realized he had opened Pandora's box and this woman in her madness could match him at just about anything he does. I think he finds that, in some ways, very sexy and attractive. But he's not really set up to love in the way a regular person is. I think there are sparks and intensity and weird passion of a sort to their relationship, but I would not call it a loving relationship in the traditional sense".

==Fictional character biography==
===DC Animated Universe===
{{main|DC Animated Universe}}

Harley Quinn first appeared in ''[[Batman: The Animated Series]]'' (1992–1995), voiced by [[Arleen Sorkin]], who subsequently reprised her role in other [[DC Animated Universe]] series, including ''[[Superman: The Animated Series]]'' (1996–2000), ''[[The New Batman Adventures]]'' (1997–1999), ''[[Static Shock]]'' (2000–2004), and ''[[Justice League (TV series)|Justice League]]'' (2001–2004), as well as the film ''[[Batman Beyond: Return of the Joker]]'' (2000).

Originally a career-oriented [[psychiatrist]] , Dr. Harleen Quinzel's life took a radical turn when she chose to take an internship at [[Arkham Asylum]] for a semester of college. Convinced by the [[Joker (character)|Joker]] himself to do it, Harleen interviewed him and learned he was abused as a child by his alcoholic father (later learning this backstory to have been one of several different stories he had told to others, some with different details each time), and after more interviews, determined [[Batman]] was the primary source of the Joker's anger and was to blame for his actions, but that she also had fallen in love with him. Harleen helped the Joker escape and, renaming herself Harley Quinn, became his sidekick in hopes that she could win his love, going on a crime spree across the [[United States of America]].<ref name="Mad Love">"[[The Batman Adventures: Mad Love#In other media|Mad Love]]{{Broken anchor|date=2025-01-25|bot=User:Cewbot/log/20201008/configuration|target_link=The Batman Adventures: Mad Love#In other media|reason= The anchor (In other media) [[Special:Diff/1183331081|has been deleted]].}}" (''[[The New Batman Adventures]]''; 1999)</ref>

After assisting Joker in attempting to assassinate [[Jim Gordon (character)|Commissioner James Gordon]] by planting a bomb at a dinner in his honor, she was subdued by Batman, and subsequently an accomplice in virtually all of Joker's criminal schemes.<ref>"[[Joker's Favor]]" (''[[Batman: The Animated Series]]''; 1992)</ref> On occasion, she would be kicked out of Joker's gang when unintentionally upstaging or annoying the Joker, on one of these occasions teaming up with [[Poison Ivy (character)|Poison Ivy]], with the two becoming close friends and a successful crime duo independently.<ref>"[[Harley and Ivy]]" (''[[Batman: The Animated Series]]''; 1993)</ref> While imprisoned on her own in [[Arkham Asylum]], Batman offered her a pardon in exchange for helping him track down the Joker after he had stolen a nuclear bomb.<ref>"[[Harlequinade (Batman: The Animated Series)|Harlequinade]]" (''[[Batman: The Animated Series]]''; 1994)</ref> The day she is declared rehabilitated and paroled, Harley's hyperactivity and unfamiliarity with the "real" world leads to her accidentally kidnapping someone and being returned to Arkham yet again.<ref>"[[Harley's Holiday]]" (''[[Batman: The Animated Series]]''; 1994)</ref>

In the 31-episode ''[[Gotham Girls]]'' web series, Harley joins forces with [[Poison Ivy (character)|Poison Ivy]] and [[Catwoman]] in a co-starring role.

After several failed attempts at rehabilitation, Harley returns to the Joker's side. However, after another failed attempt to kill Commissioner Gordon leads the Joker to forget their anniversary, Harley re-examines her life and decides that as Batman was the cause of the Joker's obsession, she should capture and kill him herself, doing so by falsely pretending to have found sanity and luring Batman into a trap. Recognizing Harley to have come closer to killing him than Joker has ever done, Batman tricks her into facilitating his escape by making her call the Joker and tell him what she has done, knowing that he would not allow anyone other than himself to kill Batman, pushing her aside and unknowingly knocking her out a window. Recovering in Arkham, Harley decides that the Joker will never truly love her, before returning to her devotion upon seeing that he has left her a rose in a vase by her bedside table, with a note hoping that she gets better soon.<ref name="Mad Love" /> Harley later references having convinced the Joker to attend [[couple's counseling]] with her.<ref>"[[List of Justice League episodes#48|Wild Cards, Part II]]" ([[Justice League (TV series)|''Justice League'']], 2003)</ref>

In the film ''[[Batman Beyond: Return of the Joker]]'', flashbacks reveal Harley's apparent final actions after returning to the Joker again were assisting him in kidnapping [[Tim Drake]] and torturing him into insanity to transform him into their son "J.J", so that they can start a family together. She later fought [[Batgirl]] who angrily chastised her for even helping Joker commit a heinous act but fell deep into an abyss, leading to the latter presuming her dead, though she survived as depicted in the present, where she appears at the end of the film, revealed to have reformed and become the grandmother of the Jokerz members, the Dee Dee Twins, who address her as "Nana Harley".

===DC Universe===
{{main|DC Universe}}

[[File:Classic and modern Harley Quinn.png|thumb|257x257px|The classic and modern iterations of Harley Quinn. Art by [[Terry Dodson|Terry]] and [[Rachel Dodson]].]]
Harleen Quinzel was a psychologist at Arkham Asylum, and after meeting the Joker, she became his frequent accomplice, took on the name Harley Quinn, and got into a codependent relationship with him. She eventually splits up with him, and becomes a solo criminal, forming a criminal gang called the Quinntets. Following the Quinntet's dissolution, Harley Quinn moves to Metropolis with her best friend Poison Ivy, where she works as a love columnist in the ''[[Daily Planet]]'' under the alias Holly Chance. She then moves back to Gotham City, where she then voluntarily incarcerates herself in Arkham.<ref name="auto" /> Harley Quinn then spends a year applying for parole, only to see her request systematically rejected by Bruce Wayne, the layman member of Arkham's medical commission. She is kidnapped by Peyton Riley, the new female [[Ventriloquist (character)|Ventriloquist]], who offers her a job; Harley turns the job down out of respect for the memory of Arnold Wesker, the original Ventriloquist, who attempted to cheer her up during her first week in Arkham while the Joker was still on the loose. She then helps Batman and Commissioner Jim Gordon foil the impostor's plans. Although Riley escapes, Bruce Wayne is impressed with Harley's effort at redemption and agrees with granting her parole.<ref>''Detective Comics'' #831 (June 2007) by Paul Dini</ref> She then briefly joins the [[Secret Six (comics)|Secret Six]], then decides to quit.<ref>''Birds of Prey'' #105 (June 2007)</ref>

====''Final Crisis''====
{{main|Countdown to Final Crisis}}

During ''[[Countdown to Final Crisis]]'', a reformed Harley Quinn resides in an Amazon-run women's shelter. Having abandoned her jester costume and clown make-up, she now only wears an Amazonian stola or chiton. She befriends the former Catwoman replacement [[Holly Robinson (character)|Holly Robinson]] and then succeeds in persuading her to join her at the shelter, where she is working as an assistant. They are both brought to [[Themyscira (DC Comics)|Themyscira]] by "Athena" (really [[Granny Goodness]]) and begin Amazon training. Holly and Harley then meet the real Athena and encounter Mary Marvel. The group reveals Granny's deception, and Holly, Harley, and Mary follow her as she retreats to [[Apokolips]]. Mary finds the Olympian gods, whom Granny had been holding prisoner, and the group frees them. Harley is granted powers by Thalia as a reward. Upon returning to Earth, the powers vanish, and Harley and Holly return to Gotham City.

====''Gotham City Sirens''====
{{main|Gotham City Sirens}}

Harley Quinn then joins forces with Poison Ivy (Pamela Isley) and Catwoman (Selina Kyle) in the series ''[[Gotham City Sirens]]''. In ''[[Gotham City Sirens]]'' #7, Harley Quinn visits her family in her hometown of [[Bensonhurst]], Brooklyn, during the holiday season. Harley's father is a swindler who is still in jail, and her brother, Barry, is a loser with dead-end dreams of rock stardom. Her mother, Sharon, wants her to stop the "villain and hero stuff". The dysfunctional, "horrible" experience while visiting family causes her to return home to the Sirens' shared Gotham City hideout where Harley, Catwoman, and Poison Ivy spend the rest of Christmas together. Following several adventures with Catwoman and Ivy, Harley betrays them and breaks into Arkham Asylum, intending to kill the Joker. However, Harley ultimately chooses instead to release the Joker from his cell, and together the two orchestrate a violent takeover of the facility that results in most of the guards and staff members either being killed or taken hostage by the inmates.<ref>''Gotham City Sirens'' #20–23. DC Comics.</ref> Harley and the Joker are eventually defeated by Batman and Catwoman, and Harley is last seen being wheeled away while bound in a straitjacket and muzzle.<ref name="Gotham City Sirens' 2011"/> Shortly afterward, Poison Ivy breaks into Harley's cell and attempts to kill her for her betrayal, but instead offers to free her if she helps her kill Catwoman, who had left both of her fellow Sirens behind in Arkham. Harley agrees, and the two set out to trap Catwoman.<ref name="ReferenceC"/> During the ensuing fight, Catwoman says she saw good in them and only wanted to help. As Batman is about to arrest them, Catwoman helps the two of them escape.<ref>''Gotham City Sirens'' #26 (August 2011). DC Comics.</ref>

====''The New 52'' and ''DC Rebirth''====
{{main|The New 52|DC Rebirth}}

Like her previous incarnations, Harleen Quinzel was still the Joker's psychologist, but before she becomes Harley, the Joker pushes her into a vat of chemicals, bleaching her skin white and driving her insane (this story later revealed as a lie Harley tells herself, having jumped into the vat herself). Harley Quinn is forced to join the Suicide Squad by Amanda Waller. Harley Quinn then leaves Gotham City and moves back to her hometown of [[Brooklyn]] and resides in [[Coney Island]].

====''Infinite Frontier''====
{{main|Infinite Frontier}}

Harley Quinn moves back to Gotham City in an attempt to reestablish herself as a hero, aiding the Batman Family and trying to make up for her past "where she often [[Enabling|enabled]] the Joker".<ref name="phillipsdcinterview"/>

On Robbie's portrayal of the character in the film, Dini commented: "I think they really got the essence of the character down, and they made her quite a lot of fun and appealing in so many ways. She's not totally the animated version, and it's not totally the Jimmy Palmiotti and Amanda Conner version, but it kind of borrows from all of them and creates its own reality and its own fun. There are so many moments in that movie that I just think are wonderful. [...] When I saw her running, laughing hysterically, pushing a shopping cart full of [[Peeps]], I said, "That's my girl". All those little [[impish]] things that she did in the movie – sitting down eating cereal, watching [[Tweety Bird]] cartoons, and just kind of skipping through life cheerfully oblivious of the devastation she's caused – that's Harley".<ref>{{cite web|title=Paul Dini Talks Batman: the Adventures Continue|website=DC Universe Infinite|date=April 3, 2020|first=Joseph|last=McCabe|url=https://www.dcuniverseinfinite.com/news/paul-dini-talks-batman-adventures-continue/|access-date=September 6, 2021|archive-date=September 7, 2021|archive-url=https://web.archive.org/web/20210907123239/https://www.dcuniverseinfinite.com/news/paul-dini-talks-batman-adventures-continue/|url-status=dead}}</ref>

====''Batman: The Enemy Within''====
Harley Quinn appears in ''[[Batman: The Enemy Within]]'' (the sequel to ''[[Batman: The Telltale Series]]''), voiced by [[Laura Post]].<ref>{{cite web|last1=Dornbush|first1=Jonathon|title=Telltale's Batman: The Enemy Within First Harley Quinn Clip Revealed|url=https://www.ign.com/articles/2017/09/23/telltales-batman-the-enemy-within-first-harley-quinn-clip-revealed|website=IGN|date=September 23, 2017|access-date=September 27, 2017}}</ref><ref name="btva" /> This version was driven insane following her father's long bout with mental illness and eventual suicide. Attempting to avoid her father's fate, she joins a criminal organization called the Pact to steal a virus able to cure her hereditary condition. This depiction initially reverses the dynamic between Harley and the Joker. Quinn manipulates and abuses her former patient at Arkham Asylum, named "John Doe", who is infatuated with her. As the series progresses, John's confidence will increase, and depending on the player's choices, he will either aid Bruce Wayne in capturing Quinn or transform into the traditional version of the Joker. In the latter outcome, Harley becomes the Joker's girlfriend, and the two use the virus to threaten Gotham City.
