[[caption-width-right:330:Old School.]]

The page for the comic series spotlighting everyone's favorite CanonImmigrant and PerkyFemaleMinion, Dr. Harleen Quinzel, also known as Harley Quinn!

The first series lasted for 38 issues, from December 2000 to January 2004, plus a special tying in with the ''Our Worlds At War'' event, with the complete run collected in graphic novels. Initially it was written by Karl Kesel, with A. J. Lieberman taking over for the last year or so.

The series begins when, after a failed scheme, SelfDemonstrating/TheJoker gets so pissed at Harley that he kicks her out of his gang - the rest of the series deals with Harley trying to make it on her own. Initially she tries freelance henching, but that doesn't exactly work out, so she starts her own gang instead. With... mixed results.

A running theme in the first part is Harley's childlike inability to take responsibility for her own actions, or even acknowledge/realize any consequences besides her having fun, which reaches TearJerker levels at times, though the comic itself is more than a little madcap. Also heavily involved is Harley's [[InLoveWithLove love of Love]], and her being willing to do pretty much anything in the name of it.

The last set of storylines, following the change in writers, happen after a time skip and feature a noticeable GenreShift to a more noirish style, downplaying Harley's cheery quirks and madcap adventures and instead playing her more like a jaded expy of Comicbook/{{Catwoman}}. This did not last.

In true tradition of the Batman side-comics, the Caped Crusader himself does not appear very often, nor, interestingly enough, does the Joker beyond the first issue or so.

Note that the title character predates this series. She had debuted in ''WesternAnimation/BatmanTheAnimatedSeries'' during 1992. Her first comic book appearance was in ''ComicBook/TheBatmanAdventures'' #12 (September, 1993). Her introduction to the mainstream DC universe took place in the one-shot ''Batman: Harley Quinn'' (October, 1999).

Harley got a second series in the ComicBook/{{New 52}}, which debuted in November 2013, and has had a number of specials. It's written by Jimmy Palmiotti and Amanda Conner of ''ComicBook/PowerGirl'' fame, and follows Harley and her antics on Coney Island after she inherits an apartment complex there. As of this writing, it is [=DC=]'s highest-selling comic book with a female lead.

'''''Note: This isn't a character page.''''' This page is about Harley's solo series and the character/plot tropes therein. For character tropes that appear in the DCU as a whole (and/or appearing elsewhere, but ''not'' these series), see [[Characters/BatmanRoguesGallery her character page here.]]

!!These Series Contain Examples Of:


[[folder:Pre-New 52 series]]
* AesopAmnesia: A major lesson Harley learns in the series is that she doesn't need the Joker in her life. Unfortunately, at some point between the end of the series and her next appearance in the comics, Joker must have gotten to her again, which is sadly ''very'' in character.
* AllegedLookalikes: InUniverse. The third issue has a man who says he can never hold down a job because he looks just like...''SelfDemonstrating/TheJoker'' (Harley had guessed Al Gore with a bad haircut). He doesn't and is clearly delusional, eventually leading to his own death out of sheer idiocy.
* AntiVillain / AntiHero: Harley, who fluctuates between a good-hearted villain and devious but heroic ''very'' rapidly. Sometimes in the same issue.
* ArtShift: Several times in the first part of the series the art shifts to a sort of "Harleyvision," which shows the world how she sees it: rendered in more cartoony version of the DCAU style, where nobody dies and everything plays out like a WesternAnimation/LooneyTunes cartoon. This becomes harrowing at times, [[http://scans-daily.dreamwidth.org/23706.html such as when Harley blows up a traitorous minion]] and we see, in Harleyvision, a Looney Tunes-esque scene where the woman's face is covered in soot, her hair is frizzy, and her eyes are swirled like a stunned cartoon character after an explosion... and then later someone runs through the same hallway and we instead see the truth: the minion's mangled corpse.
* BadBoss: Harley runs into this twice - with Joker and Two-Face. She herself kills several of her minions, but only after they [[TheStarscream betray her,]] with one notable exception.
* BiTheWay: True to form, this series has a long stretch of time with Harley and Ivy being very... close roommates, this time in Metropolis. Amusingly, at the same time Harley - in disguise as a mild mannered reporter - has a semi-fictitious relationship with Jimmy Olsen.
* BlondesAreEvil: Though not naturally.
* BoundAndGagged: Happens several times to Thorn after she is defeated by Harley and Ivy. Also happens to Sasha Bordeaux, Agent Chispazo, and a number of other characters.
* [[BunnyEarsLawyer Bunny Ears Psychologist]] - Harley, in spades. She barely ever acts like anything but an unrestrained loon, but occasionally she makes it known that she's ''still'' a university-educated psychologist. Later in the series, after she mostly loses the "bunny ears," she gets a day job in the field and takes a few patients (one or two of which want to kill her).
* CanonImmigrant: Harley, from WesternAnimation/BatmanTheAnimatedSeries: while she appeared in the comics before this, this was where she came into her own and got a lot of character establishment.
* ChildrenAreInnocent: With Harley as a (wo)manchild rather than a regular one. She is, however, widely regarded by others as being extremely innocent, of the "not aware of doing evil" variety, just, in her mind, having fun - this does, however, involve a laundry list of psychologically stunted systems of denial. She sees the world like a game of make-believe, and is oblivious to the fact that she is hurting people and doesn't truly acknowledge the danger of what she does or other people's danger to her - though she in more lucid moments claims this is less innocence and more a rejecting of the world in favor of her own reality.
** InnocenceLost: A major plot point in the second half, involving Harley herself, who realizes what kind of person she truly is and fully, if sadly, embraces it, and a girl she kidnapped, who loses her sight thanks to Harley's greed. [[InvertedTrope Inverted]] with the girl in question, who regains a bit of her innocence after being free of everyone pursuing her (now that she doesn't have what they want anymore) to the point that she ''pities'' people like Harley.
* ClarkKenting: Harley parodies (and lampshades) this trope while in Metropolis, disguising herself as a mild-mannered, if kooky love columnist for the Daily Planet - without ever realizing one of her coworkers is Superman.
* CrapsackWorld: Gotham, as par for the course.
* EvilVsEvil: And a lot of it.
* FauxActionGirl: Gritty vigilante Thorn tries is easily defeated and tied up by Harley and Ivy in each of her appearances, barring the first.
* ForScience: At one point Harley and Ivy capture a meddling Thorn in Metropolis, and while having her at their mercy discover her split civilian "Rose" personality. Harley is intrigued and gets the idea to put her through even more emotional trauma to see how many times they can get her personality to split. Ivy plays along, but she on the other hand [[ForTheEvulz just wants to torture her for the hell of it.]]
* FreudianExcuse / StartOfDarkness: One story gives us a flashback to before Harley met the Joker, where a psychological experiment gone terribly wrong with her old fiancÚ, resulting in his suicide, drives her to a philosophy of meaninglessness and emotional fragility long before she ever sets foot in Arkham, and it's this, if anything, that starts her on her road to villainy, with the Joker just guiding her to her destination.
* FriendOrIdolDecision: Harley kidnaps a girl whose eyes are needed for some sort of convoluted and very lucrative underhanded venture - but while she is protecting her from others who want the money (and don't care whether the girl lives), the two sort of bond. So then, it comes down to Harley whether to give up the girl and make a mint or save her. Long story short, the girl ends up blind and Harley ends up richer, completely depressed and unable to look at herself in the mirror.
* GeniusDitz: The series itself goes back and forth as to whether Harley truly is a brilliant psychologist or whether she cheated her way through school and was not fit to do it in the first place - though it eventually settles on the former.
* GenreShift
* GirlishPigtails: When out of costume, she usually styles her hair like this.
* GirlsNightOutEpisode: Several times in the beginning of the series, where a female villain eventually teams up with other female villains and they fight female heroes, particularly the "sleepover" episode.
* GoodAngelBadAngel: Often. Her shoulder devil alternately appears as either the Joker or herself in costume, while her shoulder angel is consistently Dr. Harleen Quinzel. Fairly often, however, they shift roles from "good/evil" to "reason/insanity" or "common sense/impulsiveness."
* HappyHarlequinHat: Goes with the costume.
* IgnoredEnamoredUnderling: To the Joker, of course. The series as a whole is one long attempt by her to get over this, especially the first half, with varied success.
* JetPack: Harley steals one at some point. She runs into trouble when it explodes.
** ToastedBuns: Harley references this while jetpacking away from Superman - which makes sense, as the jetpack in question is small enough to fit in her lower back and at one point is directly facing into her behind.
* KilledOffForReal: Harley, at one point, gets caught up in a massive explosion. The next few issues take place in Hell. [[BackFromTheDead She gets better.]] Also, Lewis, though Harley never registers that she killed him.
* LampshadeHanging: Harley mentions in issue 13 how it's always night time in Gotham City.
* LikeABadassOutOfHell: Third type. She's thrown out because she keeps spreading her positive attitude, not something that they like in a place where you're supposed to "Abandon All Hope".
* LoveMakesYouCrazy: Harley, natch.
* LoveRedeems: Of a sort. Harley, being a lover of love, decides to help it grow wherever she can - being in love is the easiest way to get her to spare you. Early on she fights Two-Face to save a hostage he was taking as his own because she felt the story was romantic, and later on she plays matchmaker to a pair of bounty hunters trying to bring her in.
* MentorOccupationalHazard: Happens twice - to Lewis in the beginning, who was trying to guide the driftingly insane Harley to something better than the world he was stuck in. Harley herself killed him, shooting him through the chest to stop him from killing hostages, though she does not acknowledge that she had fatally injured him. Later happens to the old ex-con Harley befriends, who was implied to have done a lot to help her into the relative sanity she had by the end of the series.
* NietzscheWannabe: Gotham breeds this - in this series there's Joker, Lewis (to an extent: this is one of the reasons why he did not feel sad about finally being killed), and Harley to an extent.
* PsychoExGirlfriend: For a time, Jimmy Olsen of all people dates Harley [[ClarkKenting without realizing who she is.]] This does not end well for Jimmy when it doesn't work out.
* PsychoForHire: Several, including a traitorous henchman Harley for some reason continues to hire.
* [[PsychopathicManchild Psychopathic Womanchild]]: Harley herself, who acts and thinks like a child at play; this is particularly noticeable with the addition of the aforementioned Harleyvision - the world as she sees it where, again, ''nobody dies'' and everything is like a game or cartoon. Harley herself does not register the true consequences of her actions, and doesn't even realize she's been killing people until she meets with up her victims in Hell (long story), and even then it takes her a while to realize they're dead - she thinks she's still alive because she doesn't register having killed anyone.
* SexyJester: Naturally. She even tries to keep the theme in her own gang for a while.
* ShipperOnDeck: During the first run, Harley notices the UnresolvedSexualTension between two detectives and decides to encourage them to get together. [[spoiler:She ends up killing Lewis, the most developed and sympathetic of her henchmen, to keep him from being a MomentKiller -- although she thinks it's just a flesh wound thanks to Harleyvision.]]
* ShoutOut:
** In one of the early [[GirlsNightOutEpisode Girls' Night Out issues]], the obscure [[LovelyAngels duo of Bad Girls]], the Body Doubles, appear cosplaying as Creator/AdamWarren's version of the ''ComicBook/DirtyPair''. The vigilante Thorn also shows up in a disguise that looks like Creator/DarkHorseComics' "Ghost" character.
** Volume one of the collected editions is called "Preludes and Knock Knock Jokes", a riff on the first volume of ''ComicBook/TheSandman''.
** The issues with the CarnivalOfKillers includes expie of Clownface and Panda from ''ComicBook/BodyBags''.
* SlumberParty: Harley held a supervillainess sleepover in one issue.
* SplitPersonality: Two-Face appears at one point, so that's a given. However, the storyline where he appears also involves a businessman allegedly having an affair with a woman who turns out to be his wife's split personality. Also, Rose and Thorn appear when Harley goes to Metropolis.
* TheStarscream: When Harley starts her own gang she gets several, including a remnant of one of Joker's gangs who is disappointed she isn't more violently destructive.
* StartOfDarkness: It's Harley's comic, so of course we'll see it. But the kicker is that it's not how you might remember it.
* TooSpicyForYogSothoth: Her constant, unyielding focus on love and joy caused her to get banished from hell.
* TheUnreveal: ''Weaponized'' in fact. Harley's StartOfDarkness involved her professor's experiment killing her boyfriend, but it's never shown whether Harley shot him in assisted suicide or he just shot himself. Harley finds out that professor has been after the answer for all these years and refuses to tell him.
* VillainousHarlequin
* VillainProtagonist: Of course.
* WidgetSeries: It's hilariously goofy. Let's leave it at that.

[[folder:New 52 series]]

[[caption-width-right:330:ComicBook/{{New 52}} School.]]

* DependingOnTheArtist: While she's drawn by several artists in issue 0, the colors of her clothes and hair alternate between "red and black" or "red and blue". Her permanent artist goes for the red and black colors.
* [[DifferentWorldDifferentMovies Different World, Different Comics]]: Averted in issue #0. The comics Harley is reading are all from DC Comics' ''ComicBook/{{New 52}}''.

* FlashForward: The ''Futures End'' tie-in, as part of the theme for the New 52 comics that month, flashes five years ahead to feature Harley meeting up with the Joker on a desert island (and [[{{Foreshadowing}} dropping hints as to what's about to happen in the present day]]).

* ImagineTheAudienceNaked: In #0, Harley finds herself dreaming that she is performing in front of an audience of comic book fans. She forgets her lines and tries to remember this piece of advice, but gets confused as to whether she is supposed to imagine the audience naked or herself naked. Ultimately she imagines herself naked and starts belting out her lines, only the dream changes so she is now in church.
* ImprovisedWeapon: In issue 3, to stop the love-crazy convicts that are after her, Harley breaks into a tool store to gear up. Her arsenal includes a weed whacker, [[AnAxeToGrind an axe]], [[NailEm a nail gun]], and a [[ExplosiveBarrels propane tank]].

* LighterAndSofter: Than most of the other books in the New 52, which tend to be very serious.
* LimitedWardrobe: Averted, as she's shown to have different outfits, most of them in red and black. She wonders how Superman can wear the same thing all the time.

* MeaningfulName: Sy Borgman, also known as Syborg, got cybernetic limbs at some point in his life.
* MulticoloredHair: The left side of Harley's hair is black and the right side of her hair is red, matching her clothes.

* RasputinianDeath: One of Sy's enemies is an old man in a coma. Sy cuts his life support, but he doesn't die. Sy cuts his breathing tube, but still doesn't die. Then Harley takes a crack at it and blows into the breathing tube, [[BloodyHilarious making the man's arteries explode]]. That finally does it.
* RetiredBadass: Issue 4 introduces [[{{Cyborg}} Sy Borgman]], a former government agent of the Sixties who got blown up taking out a Russian terrorist group. His arm, leg and eye were replaced state-of-the-art (for the time, at least) bionics, but in his old age, they're just extra weight.

* ShaggyDogStory: In issue 4, one of Harley's patients is a elderly woman who is sad that her family rarely sees her. Sickened, Harley goes to the family's house, kidnaps them, forgets about them for a while, remembers them, takes them to the pier, and berates them for neglecting their elder. However, the elderly woman's son reveals [[spoiler:that they see her all the time; she just has Alzheimer's disease, which makes her forget]]. Harley then realizes she should've looked at the files first.

* VictoriasSecretCompartment: Harley finds her wanted poster in the shirt of a hitwoman that tried to kill her. [[MistakenForGay Big Tony thought she was searching for something else at first]].
