[[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 ''ComicBook/OurWorldsAtWar'' 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, ComicBook/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'' in 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 ran for 31 issues from November 2013 to July 2016, and 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.

In June 2015, it got a SpinOff miniseries by Palmiotti, Conner, and Justin Gray, ''Harley Quinn/Power Girl'', recounting a lost adventure set during the duo's partnership in the main series, featuring Vartox of ''Power Girl'' fame. In December of the same year, DC launched a second spin-off called ''Harley's Little Black Book'', by Palmiotti and Conner, a ''ComicBook/TheBraveAndTheBold''-style team-up series that features Harley partnering with a different DC hero or villain in each issue. In April 2016, it got a third spin-off, the miniseries ''Harley Quinn and Her Gang of Harleys'', written by Palmiotti and Frank Tieri.

A third series launched in August 2016 as part of ''ComicBook/DCRebirth'', now twice-monthly, but with little initial change from the previous volume, keeping Palmiotti and Conner as writers, and Harley on Coney Island. From issue #36, Frank Tieri took over as writer for nine issues, before Sam Humphries became the new ongoing writer with #45.

'''''Note: This isn't a character page.''''' This page is about Harley's various solo series and the tropes therein. For character tropes related to all appearances by Franchise/TheDCU incarnation of the character, see Characters.BatmanRoguesGalleryPart1.

!!These series provides 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...''ComicBook/TheJoker'' (Harley had guessed UsefulNotes/AlGore 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 a 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.
* BarredFromTheAfterlife: In one issue Harley was killed and sent to Hell, but was banished from the place due to her focus on joy and love. Clearly, in a place where you're supposed to "Abandon All Hope", the staff doesn't like having someone like that around.
* BerserkButton: The entire Bat-family attack Harley when she dresses as ComicBook/{{Batgirl}}. Dick, especially, is very pissed.
* 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 ComicBook/JimmyOlsen.
* 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.
* 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.
%%* EvilVersusEvil
%%* {{Fanservice}}
* 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.]]
* FourthWallObserver: Usually an imaginary Harley comments to viewers on events in the comic.
* FreudianExcuse / StartOfDarkness: One story gives us a flashback to before Harley met the Joker, where a psychological experiment gone terribly wrong with her old fiancé, 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 has her hair in pigtails. Fitting considering how childish she is.
* 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: Completing her harlequin inspired outfit is her iconic red and black hat, though it has two flaps and no bells.
* 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.
* 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.
* JetPack: Harley steals a jet pack at some point. She runs into trouble when it explodes.
* 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.
* LoveMakesYouCrazy: Harley's backstory, of course.
* LoveRedeems / LoveFreak : 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.
* MaleGaze: If an issue is drawn by Terry Dodson, you can be sure that there is a butt shot of Harley or ComicBook/PoisonIvy (also Catwoman once).
* 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.
* MsFanservice: She often wears a tight jester suit and switches it out for what can best be described as a bikini designed to resemble her former appearance.
* 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
* 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 Adam Warren's version of the ''LightNovel/DirtyPair''. The vigilante Thorn also shows up in a disguise that looks like Creator/DarkHorseComics' [[ComicBook/GhostDarkHorseComics "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 expies 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.
* StrawNihilist: 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.
* 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.
* 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 the professor has been after the answer for all these years and refuses to tell him.
* VillainProtagonist: While she has some heroic moments the series is largely about her committing a lot of crime and trying to establish her own criminal empire without the guidance of the Joker.

[[folder:New 52/Rebirth series]]

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

* AccidentalInnuendo: Bernie, Harley's taxidermy beaver, is subject to this in-universe, such as when Harley asks Ivy if she wants to "meet [her] beaver", which Ivy misinterprets sexually before seeing what Bernie is.
* ActuallyPrettyFunny: ComicBook/PoisonIvy spends most of Issue 7 being exasperated at Harley, but she lets out a brief laugh after Harley says the assassin [[ItMakesSenseInContext ripped in half by a fence ]]"went [[CrossesTheLineTwice Splitsville]]".
* AllJustADream: Most of issue 0 takes place in a dream Harley is having after wishing for her own comic. It's a very [[MindScrew crazy]] dream where she talks with the comic's writers and holds auditions for artists to draw her comic.
* AllThereInTheManual: The fifth graphic novel collection, ''The Joker's Last Laugh'', has a bonus story, "Be Careful What You Wish For", which introduces [[BroughtDownToNormal ex-genie]] Jimm Salabim.
* AlterKocker: Sy Borgman is an old man who speaks Yiddish almost every time he opens his mouth.
* AlternateSelf:
** The Power Girl who shows up in the series is the Kara from Conner's pre-''ComicBook/{{Flashpoint}}'' series, not the New 52 Kara, saying in ''Harley Quinn/Power Girl'' that she's the sole survivor of her timeline and had that whole Earth-2 thing happen. How she ended up crashlanding near Harley is left mysterious.
** Harley meets her own alternate self when she visits [[ComicBook/DCComicsBombshells the Bombshells world]] in ''Little Black Book'' #4, which has... unexpected consequences.
* AntiHero: Harley doesn't try to cause trouble, it just happens, and she enforces justice in her own way, like freeing a neglected dog and punishing the owner, and rescuing an old woman who was robbed and giving her some money despite her own day going wrong in every way possible.
* ArsonMurderAndJaywalking: Almost literally. The criminals on the van in Issue 3 are an arsonist, eight murderers, two mass murderers, two serial killers, and a pervert.
* ArtShift: In issue 0, Harley realizes that she needs an artist to draw her comic. The writers give her ''seventeen'' to choose from. Artists include [[ComicBook/PowerGirl Amanda Conner]], Jim Lee, Creator/BruceTimm, and [[ComicBook/TinyTitans Art Baltazar]]. In the end, she settles on Chad Hardin as her artist.
-->'''Harley:''' Seventeen artists to tell me how good I look? Eat your heart out, Pud'n!
* AscendedFangirl: The first issue of ''Harley's Little Black Book'' reveals that Harley is a huge Wonder Woman fan, and in the book Harley gets to team up with her.
* AttentionDeficitOohShiny: Happens to Harley a lot. In one issue she plans to break into Arkham to rescue Ivy, but is distracted by the pizza in the restaurant she parachutes into.
* AuthorAvatar: In issue 0, the comic's writers, Jimmy Palmiotti and Amanda Conner, appear to Harley as disembodied voices. Jimmy's speech balloon is blue and Amanda's is green. They appear in person in Darwyn Cooke's segment.
* BachelorAuction: In the ''Harley Quinn Valentine's Day Special'' #1, Bruce Wayne is New York for a charity bachelor auction, and Harley decides she has to be the one to win a dream date with Franchise/TheDCU's most eligible bachelor. HilarityEnsues.
* BaitAndSwitch: Issue 2 opens up with Harley back together with the Joker, but it turns out that it was just a wax statue of him.
* BeautifulDreamer: In issue 2, Ivy wakes up in bed with a sleeping Harley [[spoiler:surrounded by several cuddly cats and dogs]]. She says "Aww…my cute little psycho" and kisses Harley's cheek before wandering off.
* BiTheWay: Harley keeps up her very close friendship with Ivy, as well as being romantically interested in men. Amanda and Jimmy [[WordOfGod confirmed]] that as far as they're concerned, Harley and Ivy are girlfriends who aren't hung up on monogamy. As time goes on Harley and Ivy becomes more openly affectionate and are seen kissing.
* BigBreastPride: In #22, Harley is briefing the Gang of Harleys when she notices that Harley Queen is topless. She asks Queen why, and Queen replies:
-->"Number one, just ''look'' at these! Number two... Well, just ''look'' at 'em!"
* BigDamnHeroes: Big Tony shoots a hitwoman that was sneaking up on Harley while she was relaxing.
* BigEater: This Harley sure can stuff her face.
-->'''Nate''' ''(the hot dog stand guy)'': When you eat that much, where does it all go?\\
'''Harley:''' Ha! You'll figure it out when I walk away from here.
* BikerBabe: Harley rides around in a [[VisualPun Harley Davidson]] and tends to wear a red and black biker jacket.
* BitingTheHandHumor:
** Dan [=DiDio=] shows up in the Comic-Con special, where among other things he mentions that the next New 52 September event will have 4-D covers - basically 3-D, with the 4th D standing for [=DiDio=], as he'll be in the background of every issue - that involved mining one of the most remote places on Earth and melting part of the South Pole in the process, and that DC will be launching a line with ''no'' editors to overlook the content which they don't expect to sell at all, so they're giving them a low print run.
** Harley's comic faces rejection at Comic-Con because DC isn't looking for anything new or original.
** In #8, Harley launches a barrage of dog poop with the Scatapult at the DC office, where a "Gnu 52" reboot (where a villain forces Zatanna to turn everyone into antelope and wildebeest) is being pitched by [=DiDio=]. You can also see Jim Lee and Geoff Johns there.
** The name of the boss demon in ''Harley's Little Black Book'' #3 is [[SdrawkcabName Nad Oidid]].
* BlackComedy: A good deal of the book is focused on this, but the crowning example has to be when Ivy and Harley are betting on which side of a fence a corpse stuck on it will fall on. They also use scientific analysis to justify their predictions. [[spoiler: As it turns out, the body splits in half and falls on both sides, making both correct.]]
* BlueAndOrangeMorality: Harley has a twisted sense of right and wrong. When she sees a dog getting neglected by his owner, she frees the dog and drags the owner by her motorcycle.
* BondageIsBad: Harley seems to be a fan of this, both as the dominant and the submissive. To give an obvious example, one issue starts with her waking up in her rather messy apartment with last night's date behind her, duct-taped to the wall; two pages later, she sees a patient dressed in a gimp outfit (her treatment consists of "integral psychotherapy" through "introspection and dissection", a fancy way of saying she hogties him). Unfortunately, this leads to a horrific nightmare where she's in bed with Mason, who turns into "Mistuh Jay" mid-embrace.
* BoundAndGagged: The comic has had a heavy emphasis on ballgags, with Harley using one to gag a victim at least once per issue as they have progressed. Harley herself was bound and gagged in the first issue of ''Harley Quinn and Her Gang of Harleys''.
* TheBoxingEpisode: In ''Harley's Little Black Book'' #5 Harley and Superman square off in the boxing ring in a story that's an homage/parody of the famous ''Superman vs Muhammad Ali'' comic.
* BreakingTheFourthWall:
** Issue 0 has Harley and [[AuthorAvatar the writers]] breaking the fourth wall so much, it'll give ''ComicBook/{{Deadpool}}'' a run for his money. The end of the issue has them swear they'll stop breaking the fourth wall by issue 1. (That doesn't stop them jumping up and down on the pieces of the wall later on, though.)
** At the end of ''Harley's Little Black Book 2'', Harley kisses [[Franchise/GreenLantern Hal Jordan]] and squeezes his butt. Why? She's seen this on the cover.
* BrickJoke:
** In Issue 0, Harley likes artist Stephane Roux's art and says she'll have him draw half of issue 2. He does.
** At the end of Issue 3, Harley throws an aphrodisiac plant Ivy gave her out of her window, after she suffered some LovePotion shenanigans because of it, and it lands in the sea lion pool at the zoo. Many issues later, there's a newspaper headline about a sea lion baby boom.
** In the annual, Harley fantasizes about being Godzilla when hurtling across New York city via catapult. The mass hallucination she induces later includes a scene of Harley as Godzilla.
* BunnyEarsLawyer: While Harley may be crazy and has an unusual appearance, she's still a licensed psychiatrist, and manages to secure a job as a therapist. Subverted in that her appearance is never noticed by others, and that she dresses up as Harleen for her job.
* TheBusCameBack: Captain Horatio Strong, an obscure character from the '70s ''Superman'' comics.
* CallBack: In the Comic-Con special, Harley's got a score to settle with Amanda and Jimmy from back in issue #0. (Yes, that was a dream. Harley's relationship with the fourth wall appears to be just as quirky as everything else in her life.)
* TheCameo:
** [[ComicBook/{{Shazam}} Mr. Mind]] shows up in the first page of ''Harley Quinn/Power Girl'' #1... only to be puked on by a motion-sick Harley.
** ''Harley Quinn/Power Girl'' #3 has Creator/GrantMorrison pop up in the middle of a MushroomSamba. Which is fitting, considering.
** Bizarro and Jimmy Olsen show up in the ''Road Trip Special'', tying into the ''ComicBook/{{Bizarro}}'' miniseries.
** ''Little Black Book'' #2 has a guest appearance from Creator/GeoffJohns as a Franchise/GreenLantern fanboy bidding against Harley for a real GL ring.
** Issue 30 features cameos from numerous DC characters in Harley's dream, including Batman, Superman, Wonder Woman, the Suicide Squad, several Bat-villains, and several of Conner's previous characters (Power Girl, Starfire, Terra).
* CaptainErsatz:
** Captain Horatio Strong is the DC version of ComicStrip/{{Popeye}}.
** Harley faces a talkative and crazy mercenary in a full red and black suit called Red Tool. [[ComicBook/{{Deadpool}} Sounds familiar, eh?]]
* CaptainEthnic: Intentionally invoked with the Gang of Harleys. The Jewish member is dubbed Hanuquin, while the Indian member is dubbed Bolly Quinn. Averted with Harley Queen. She's Chinese-American, but Harley chose to give her [[CaptainGeographic a name that reflects the fact that she lives in Queens]], rather than anything pertaining to her ethnicity.
* CarnivalOfKillers: The $2 million bounty placed on Harley's head brings a veritable army of hired killers out the woodwork looking to claim it.
* TheCasanova: Big Tony claims to have a lot of devotees.
* CatchPhrase: Harley very frequently says "Holee [awful rhyme fitting the situation]" (emphasis on the ''ho''), such as "Holee Tracheotomolee!" when she throws a knife into a would-be assassin's throat.
** Harley also says several variations on "I think I died and went to Heaven!"
** Also "Whoopsie daisies!" whenever she screws up.
* ClarkKenting: Harley tries to give an amnesiac Power Girl a secret identity by way of this. Remedied by adding a ponytail.
--> '''Power Girl:''' ''(about the glasses-only disguise)'' You must think I'm an ''idiot''. Only a moron couldn't tell the difference.
* CleavageWindow: Harley puts a diamond-shaped one on her superhero costume, and another one above her backside.
* {{Cliffhanger}}: Subverted in issue 4. Harley and Sy get caught in an explosion. The ending narration starts off with the typical "Will they survive?" thing before admitting that of course they'll live.
* ColorCodedCharacters: The Gang of Harleys in their mini and Vol. 3.
* ComicBookTime: Harley was a huge fan of Wonder Woman when she was a little girl...which makes no sense given the timeline. Given this series, [[RuleOfFunny the discrepancy was almost certainly intentional]].
* CompanionCube: Bernie, Harley's stuffed beaver, whom she also [[HearingVoices imagines speaking]]. He's [[DeadpanSnarker pretty snarky]].
%%* CoolOldGuy: Sy Borgman.
* CoversAlwaysLie: The covers of #35-6 (the Man-Bat arc) depict Man-Bat-transformed Harley as a CuteMonsterGirl with unchanged facial features. In the interior art, she's depicted with the usual Man-Bat design, including horrific bat head.
* CutAndPasteComic: The same panel is reused three times when Harley and Ivy are looking out the window and making the aforementioned bet. In Issue 4, the art is mostly reused for both times Harley drives away (after knocking down the opposing roller derby team, and after releasing the Rubenstein family.)
* CuteAndPsycho: Harley, as usual. Acknowledged when Poison Ivy calls a sleeping Harley "my cute little psycho".
* CutenessOverload: [[NightmareFetishist Harley]] when faced with an alien hydra in ''Harley Quinn/Power Girl'' #1.
* DaydreamSurprise: In #14, Harley's been having a really crappy day, but things are finally starting to look up for her... then she gets a nasty Joker-flavored surprise and wakes up.
* DeadpanSnarker: Bernie, pretty much every time his voice issues out into Harley's mind.
** Ivy, although her snark isn't nearly as venomous as before the New 52:
--> '''Harley:''' Is everyone as excited as I am?
--> '''Ivy:''' No. It's not possible.
** Santa here, after removing a humbug from Harley's ear:
--> '''Harley:''' That... That itty-bitty thing is what drove me insane?
--> '''Santa:''' Something tells me you had a pretty good head start.
* DefectingForLove: [[spoiler:Zena]] changes sides [[DecemberDecemberRomance for Sy]].
* 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:
** Averted in issue #0. The comics Harley is reading are all from DC Comics' ''ComicBook/{{New 52}}''. Near the end, she picks up a comic, not realizing that it's her own. If you look closely, you can see that it foreshadows how issue #0 will end.
** Harley's DreamSequence in issue #30 has her going to see ''[[Film/SuicideSquad2016 The Kill Yourself Crew]]''.
* DisproportionateRetribution: Harley tends to go overboard when it comes to people she thinks are bad.
* DoubleEntendre: A good helping of it, mainly coming from Harley. Complete with ThatsWhatSheSaid.
* DropTheHammer: Harley's WeaponOfChoice is a huge mallet.
* EasterEgg: In Issue 7, a rather creepy grinning face can be seen under Harley's bed.
* EmbarrassingTattoo: After being abducted and knocked out by Red Tool, Harley wakes up with a red hammer and Red Tool's phone number tattooed on her ass. Harley, needless to say, is pissed at this turn of events.
* EpisodeZeroTheBeginning: The series starts off on issue #0 with Harley choosing which artist to draw her comic. It also has her getting some property in Coney Island where the series will take place.
* EvenEvilHasStandards:
** In the first issue, Harley [[WhatADrag drags a man behind her motorcycle]] after she catches him hurting a dog.
** In issue #4, Harley kidnaps a family that she believes is neglecting their grandmother. Just as she's about to drown the BoundAndGagged hostages, she learns that the whole thing was a huge misunderstanding, and releases them.
* EvenTheGirlsWantHer: After watching Harley (non-fatally) mow down a group of rival derby girls with her car, one of her teammates remarks "Wow. That was kinda hot."
* EvenTheGuysWantHim: Both the male and female news reporters confess a desire to go on the auctioned date with Bruce Wayne.
* EvilAlbino: Harley has bleached white skin (plus her MulticoloredHair and mismatched eyeshadow) from taking a dip in the same chemicals that gave the Joker his appearance. When going to a job interview for a therapist, she uses makeup and a wig to give herself the skin color and blonde hair she had back when she was Harleen.
%%* {{Fanservice}}
* FlashForward: The ''[[ComicBook/TheNew52FuturesEnd 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]]).
* FriendToAllLivingThings: Harley goes so far as to volunteer her time at a pet shelter on Christmas, then breaks into a home to make sure the owners aren't mistreating an adopted dog.
* FunetikAksent: Harley's Brooklyn accent (although it's rather inconsistent), and several of the Russian bad guys fought by Harley and Sy.
* GangOfHats: Harley creates a gang who all dress like her in order to help her fight crime and organise her life.
* GettingCrapPastTheRadar:
** Invoked in one of the artists' sequences in Issue 0, which Conner shuts down because it [[ThinkOfTheCensors wouldn't make it past editorial]], and played straight for the title of Issue 7.
** Harley appears to say some serious profanity after her tooth is knocked out by a brutish roller derby opponent. However, it sneaks past since she's taking it out of her mouth while saying it, rendering the profanity as the garbled, "mygluggin'toooph!"
* GirlOnGirlIsHot: The burlesque play in Issue 9 where Queenie kisses Harley gets a very positive reaction from the crowd.
* HandicappedBadass: This series introduces several new ones to the DCU. Sy Borgman and the blind Coach of the Gang of Harleys are prime examples of this trope.
* HehHehYouSaidX: Harley does this a ''lot''.
-->'''Harley (after Power Girl's soda cup is shot):''' Oh, ''no!'' Don't worry, we can get another cup. Heh, I said ''[[GagBoobs cup]]''.
--> '''Harley (after Manos calls for his pipe organ):''' HA! He said ''Cosmic Organ''.
* HiredGuns: Harley has to deal with all sorts of mercenaries and bounty hunters since she has a bounty on her head worth over $2 million.
* HumongousMecha: In issue 29 Harley fights a man with both using giant transforming mecha.
* HypocriticalHumor: Harley points out the obvious case of StevenUlyssesPerhero surrounding Sy Borgman's name. Never mind that her own name is Harleen Quinzel.
* ICallItVera: In #5, we learn that Harley calls that huge hammer "Beatrice." "She never runs out of bullets."
* IDontLikeTheSoundOfThatPlace: Harley Sinn has her secret hideout on the Island of Horrible Death. Presumably she named the place herself.
* ISeeDeadPeople: According to ''Harley's Little Black Book'' #3, Harley's been able to see ghosts at least since medical school. ComicBook/{{Zatanna}} has no idea why.
* ITakeOffenceToThatLastOne: In ''Harley's Little Black Book'' #5, an alien conqueror tells Big Tony "Quiet, whimpering maggot!". Tony replies:
-->"What? I don't whimper!"
* 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.
* ImprobableWeaponUser: At one point, Harley uses some linked model trains as a whip.
* 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 [[ExplodingBarrels propane tank]].
* InLoveWithYourCarnage: Summer absolutely loves how brutal Harley can get in the roller derby - and out too, as seen by her reaction when Harley takes her car and runs over a rival team who had just defeated the Bruisers in her absence in #4. The others are pretty horrified, but Summer thinks it was "kinda hot".
* IronicNickname: One of Harley's tenants is a short guy named Big Tony.
* {{Irony}}: Before her chemical bath (and, technically, before the New 52), Harleen had to wear makeup to become Harley. Now, Harley has to wear makeup to become Harleen for a job.
* [[{{Landlord}} Landlady]]: Harley becomes one when she inherits an apartment complex on Coney Island full of circus freaks. They're nice people, but their rents alone won't pay the bills, so Harley has to get a few extra jobs to compensate.
* LeaningOnTheFourthWall: Issue 30, the last before the ''ComicBook/DCRebirth'' relaunch, is something of a commentary on ''Rebirth'', with Harley refusing to let things be changed and standing up for the past, and Ivy finding a solution that combines the best of both worlds, in line with ''Rebirth'''s intended ethos.
* LighterAndSofter: Than most of the other books in the New 52, which tended to be very serious, despite this one having a lot of death and even some gore.
* LimitedWardrobe: Averted, as she's shown to have different outfits, most of them in the red and black jester-themed pattern she's known for. She wonders how Superman can wear the same thing all the time.
* LoonyFan[=/=]StalkerWithACrush: Harley discovers she has one in issue 9. She sympathises, thanks to her own obsessive issues... and manages to persuade him to get some therapy. [[spoiler:But later the Joker manages to get in touch with the guy and things go way down south...]]
* LovesMyAlterEgo: According to the ''Valentine's Day Special'', Harley prefers Bruce Wayne over Batman, particularly when it comes to kissing (Bruce doesn't reciprocate).
* MaleGaze: There are many panels in the series focused squarely on Harley's butt.
** Issue 13 has one panel which is just the backside of her Power Girl outfit showing off the outfit's butt window.
** Issue 26 has a panel where her butt is dead center as a leering guy with a metal detector makes an unwelcome comment about it as she walks by.
** Issue 29 takes it up a level, with a panel focused on the butt of a TransformingMecha in Harley's image.
* MatchCut: A scene transitions from an imminent decapitation to a meatball falling on a diner floor.
* MeaningfulName: Sy Borgman, also known as Syborg, got cybernetic limbs at some point in his life.
* MirandaRights: Spoofed in #9 because Harley won't shut up about its terms (and even throws in a reference to Comicbook/{{Daredevil}} at the lawyer part).
* MsFanservice: Even more than the pre-New 52 version. She often is half-naked and object of MaleGaze.
* MuggedForDisguise: The first issue of ''Harley's Little Black Book'' has Harley knocking Franchise/WonderWoman unconscious so she can steal her costume.
* MulticoloredHair: Initially, the left side of Harley's hair is black and the right side of her hair is red, matching her clothes. After her makeover, she's blonde, with half her right pigtail blue and half her left pigtail red, much like her Franchise/DCExtendedUniverse look.
* MushroomSamba: A good portion of Issue 3 of Harley Quinn/Power Girl ends up turning into some weird version of ''Literature/FearAndLoathingInLasVegas''.

*** Harley references her time in the ComicBook/SuicideSquad, which is misinterpreted by the artist.
*** Bruce Timm's page not only has Harley in her ''WesternAnimation/BatmanTheAnimatedSeries'' costume, but she also does a theater version of her "[[GettingCrapPastTheRadar Rev up your Harley]]" scene where she forgets her lines.
*** Harley's original costume also appears in a portrait of her in Art Baltazar's page.

** In "Be Careful What You Wish For", Harley wishes to be Wonder Woman. Jimm Salabim asks ''which'' Wonder Woman she wants to be - the classic warrior on horseback, the [[Series/WonderWoman TV one]], the '70s comics one with the white slacks, the Perez-era one, the New 52 one... Harley asks how he knows this, given he's been stuck in a bottle for the last few centuries. Jimm says it's [[AWizardDidIt genie powers]] whose workings he doesn't understand.
** In vol. 3 issue 12, there's a kinda-sorta dream sequence going over the Joker and Harley's history that includes ''Mad Love'', with Harley in her original costume.
* NoHoldsBarredBeatdown: In #25, when the Joker tries to convince Harley to let him out when she comes to rescue Mason, Harley goes right into his cell and beats him up and follows it up by telling him she's over him and threatening to kill him if she ever hears from him again or if he ever threatens her friends and family.
* NoodleIncident: The second time Harley and Power Girl go to another dimension is skipped over.
* NoteFromEd: Queenie asks if they can't use another colour in the costumes of the Gang of Harleys, since using just red and black makes the place look like the bargain basement section at Hot Topic. [[ComicallyMissingThePoint Editor Chris Conroy takes the opportunity to plug the official Harley merchandise at Hot Topic.]]
* OffscreenMomentOfAwesome: The story takes Harley and Power Girl to a space dimension after being sent through the Clock King's portal. However, once they return to Earth, they are promptly sent back through. The book cuts to their second return. What happened in between was subsequently depicted in full in the entire ''Harley Quinn & Power Girl'' spin-off miniseries.
* TheOneGuy: Harvey Quinn is the only guy in the Gang of Harleys.
* ParkingPayback: In ''Harley Quinn Holiday Special'' #1, Harley is looking for a car to steal and decides to steal the one that is taking up two parking spaces because it is taking two parking spaces.
* PayEvilUntoEvil: Harley's not shy about killing those who try to kill her. In issue #2, a hitman tries to run her over. She ties him up and later throws him to her hungry new pets to save her stuffed beaver. The next morning, there's nothing but his bones left.
* PekingDuckChristmas: In ''Harley Quinn Holiday Special'' #1, Harley takes a MallSanta out for dinner on Christmas Eve to thank him from saving her from a humbug that was stuck in her ear (MakesJustAsMuchSenseInContext). The only place that is open is a kosher deli.
* PerfectlyCromulentWord: Harley loves these too. Only in the first page of the ''Rebirth''-branded Issue 4 we have "destructavated" and "vacationating".

** In issue 1, Harley rescues a neglected dog from his owner and keeps him as her own. The dog is much happier living with her.

* PinPullingTeeth: Bolly Quinn is shown doing this in the 'meet the gang' page of ''Harley Quinn and Her Gang of Harleys'' #1.
* {{Polyamory}}: Amanda and Jimmy refer to Harley and Ivy as "girlfriends without the jealousy of monogamy".
* PunnyName:
** Sy Borgman, and most of the Russians, whose names are actually pretty subtle until read out loud. They include: Ivana Brekemoff [[note]] I wanna break 'em off[[/note]], Kosta Armanoleg [[note]] Cost an arm and a leg [[/note]], Borya Tatierski [[note]] Bore you to tears[[/note]], Yuri Beyznatofin [[note]] Pays not often [[/note]] and Zena Bendemova [[note]] Bend 'em over [[/note]].
** Edgar's full name is Edgar Fullerton Yeung. In other words, egg foo yung.
* ARareSentence: From ''Harley Quinn and Her Gang of Harleys'' #6:
-->'''Harvey Quinn:''' One of Power Girl's robot boobs saved your life. Well, that's a sentence I never thought I was gonna say.
* 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.
* ResolvedNoodleIncident: The ''Harley Quinn & Power Girl'' miniseries described what happened during Harley's and Kara's second dimensional trip in the New 52 issue 12.
* 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 with state-of-the-art (for the time, at least) bionics, but in his old age, they're just extra weight.
* RoadTripPlot: The special one shot ''Harley Quinn Road Trip Special'' features Harley, Ivy, and Selina travelling together to get the ashes of Harley's beloved uncle. Hijinks ensue with {{Fanservice}} and [[MushroomSamba a dream/hallucination sequence]] included.
* RobotBuddy: Edgar Fullerton Yeung, or "Eggy" as Harley calls him. Either a robot or cyborg (the comic cuts away when he begins telling Harley and company his origin, returning when he finishes) shaped like an egg on a floating platform who can assimilate a variety of robotic torsos. Originally, he captured Harley simply out of loneliness, but now works as a handyman in her apartment. His later recounting of his family background implies he's a cyborg, as he mentions having parents.
* RollerbladeGood: In order to pay the bills of her new home, Harley tries out for a roller derby team. She absolutely demolishes her competition and the team leader is proud to have her aboard.
* RunningGag:
** There's much LampshadeHanging of the many {{Dream Sequence}}s and {{Mushroom Samba}}s in the series.
** Harley's repeated fangirling at Comic-Con, which consists of "Hey, it's that guy/girl who [long-winded summary of their most famous roles]. I LOVE that guy/girl!"
** Edgar's secret origin, which involves an astonishing number of NoodleImplements.
* SelfDeprecation:
** In issue 0, Harley and Catwoman try to rob a yacht and the book's writers, Jimmy Palmiotti and Amanda Conner, try to stop them. Amanda tells Jimmy not to hurt Harley because she's gonna pay their bills. Catwoman then riffs on Jimmy's other comics, All-Star Western and Batwing.
-->'''Harley:''' Is she serious?\\
'''Catwoman:''' You see the numbers on All-Star Western and Batwing? [[note]]They weren't very high.[[/note]]
-->'''Harley:''' Yeah, let's go easy on him. Maim, not kill.
** In the same issue Bernie calls Jimmy the cowboy guy because he writes ''All-Star Western''. He also calls Amanda the one who draws the [[ComicBook/PowerGirl girls with the big...]]
-->'''Amanda Conner:''' Hey, I'm talented! I can draw a '''lot''' of different-sized boobs!
** In #16, letterer John J. Hill breaks the fourth wall to complain about the lack of consideration he gets from Amanda and Jimmy, having to reletter the comic three or four times over with all the changes to the scripts they throw at him. (He also appears to be chained up.)
* SexyJester: A lot of Harley outfits have a design and color pattern similar to that of a typical court jester and show off a lot of skin.
* 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.
** Poison Ivy's plan to end the hit on Harley. While she successfully finds out who placed the hit [[spoiler:(it was Harley herself; turns out she did that while ''sleepwalking'' to ensure no one would try to disturb her in her new life - regardless of how counterproductive the whole thing may seem)]], some assassins come in and destroy the computer before she can take over and cancel the bounty, leaving Harley to deal with the problem.
* ShoutOut:
** In Issue 1, a blue and green van called the [[Franchise/ScoobyDoo Munchie Machine]] can be seen at the roller derby.

** In issue 9, Harley mentions [[Comicbook/{{Daredevil}} a blind lawyer she knows in Hell's Kitchen]]. She also references ''Series/IDreamOfJeannie''.

** The movie posters at the cinema Harley and Ivy visit in #16 all come from that month's themed variant DC covers, parodying classic movie posters. The films they see are ''Film/MadMaxFuryRoad'' and ''Film/FiftyShadesOfGrey''.
** Also in #16, Edgar's using a number of his robotic bodies to multi-task. Harley, noting how the bodies are dressed, wonders if he calls it "the Music/VillagePeople mode".
** Harley reveals in ''Harley's Little Black Book'' #3 that she bought a full set of (non-functional) ''Franchise/{{Ghostbusters}}'' equipment in case she ever needed to go ghost-hunting.
** Issue #29 is called [[Film/DestroyAllMonsters "Destroy All Mobsters!"]], featuring Harley noting that she can see [[Film/{{Titanic 1997}} "Leo an' that blue necklace!"]] in a Titanic-themed snowglobe, and wondering where Creator/CharltonHeston is upon seeing an [[Film/BeneathThePlanetOfTheApes Omega Bomb]].
** Issue #30 references ''Literature/ATreeGrowsInBrooklyn'', with the title being "A Tree Blows Up Brooklyn", and Big Tony commenting "''This'' tree grows in Brooklyn, so it's all of ours ta fight for."
** Issue #2 of Volume 3. The green alien that became a cow (and caused a ZombieApocalypse) is a reference to a famous ''ComicBook/FantasticFour'' story with the Skrulls hypnotised and turned into cows.

--> '''Big Tony:''' [[DistractedByTheSexy Yer telling me]]!
* {{Stripperiffic}}: While she had a traditionally conservative costume where only her face is uncovered, the New 52 makes her outfit incredibly revealing. This is lampshaded by Harley herself (in the Suicide Squad series), at one point referring to her look as a "stripper clown outfit".
* SugarApocalypse: Art Baltazar's page in issue 0 has her visiting the ''ComicBook/TinyTitans'' universe. She hates how sugary sweet the setting is and tries to smash the Titans with her mallet. She gets even more mad when she realizes they [[BloodlessCarnage don't even bleed]].
* SuperDeformed: Harley when pleading with Power Girl in issue 13, her eyes going anime-sized and streaming with tears.
* TakeThat:
** Harley dismisses Batman's origin in #9 as ridiculous.
** Issue 12 lampoons the cosmic elements of the Marvel Universe, namely Comicbook/{{Thanos}}, the Infinity Gauntlet, and the Cosmic Cube.
** Issue 15 features a potshot at ''Film/AvengersAgeOfUltron'' (or perhaps the perception that a billion grossing film can bomb), with a newspaper headline about a superhero BoxOfficeBomb that features an Ultron stand-in with a GagNose, whose failure is somehow blamed on Kim Jong-un.
** The ''Valentine's Day Special'' takes aim at pointless comic crossovers that go nowhere and Wall Street bankers.

* TykeBomb: The first issue of ''Harley's Little Black Book'' shows that she has always been dangerously close to losing it, such as showing an incident when she was very young where she nearly hangs one of her classmates and smashes another in the face with a book hard enough to break her nose.
* TheUnreveal: Edgar's backstory, which he tells the group after they've recovered from the hallucinogens. Once he starts telling, the comic cuts to another scene.
** In v3 #6, Tony asks Edgar what he is. Edgar tells him about his upbringing, but not about what he actually is. (He apparently has parents, so there's that.)
* UnusuallyUninterestingSight: Harley herself. Justified for her apartment building in that all of the carnival freaks live there, but no one bats an eye anywhere else she goes.
* ValentinesDayEpisode:
** Issue 3 takes place on Valentine's Day and Harley has no Valentine. To cheer herself up, she eats a berry from one of Poison Ivy's plants and goes out for a night in the town. Unfortunately, the berry turns out to be a LovePotion that makes anyone who smells her go crazy for her. And she just happens to pass by a prison bus full of convicts. Bloody hijinks ensue.
** The ''Valentine's Day Special'' sees Harley win a date with Bruce Wayne at auction (the auction gets interrupted by robbery and kidnapping, but they do manage to have the date).
* VehicleRoofBodyDisposal: Goes comically awry in ''Harley Quinn and Her Gang of Harleys'' #2.

However, he wakes up, falls off the roof of the train and gets hit by a train going in the opposite direction.

* YiddishAsASecondLanguage: With all the Yiddish Sy Borgman says, you won't have to wonder if he's Jewish.
* ZombieApocalypse: Volume 3 starts with Coney Island invaded by zombies. Their origin? An alien named Vertigax crash-landing on a farm and disguising himself as a cow, who accidentally gets butchered. After the meat-processing, we see that Vertigax has been shipped all over as various meat products (particularly Coney Island hot dogs), contaminating everyone who eats him. This, naturally, results in zombies.
