History WesternAnimation / BatmanAndHarleyQuinn

* ThemeTuneCameo: The Batmobile's ringtone for the Watchtower is a riff from the theme to ''WesternAnimation/JusticeLeagueUnlimited''.

* PuppyDogEyes: [[spoiler:At the climax, Harley unleashes "the nuclear option," combining puppy dog eyes with CryCute, in an attempt to convince Ivy to quit working with the Floronic Man. It works.]]

* YouKeepUsingThatWord: Harley is annoyed at the fact people (such as Batman) call sociopaths as "psychopaths".

* GroinAttack: Harley gives Joker one.

* ActionFilmQuietDramaScene: [[spoiler: Harold's death]] is presented in a much more somber tone than the rest of the movie, ditto can be said for the scene following it between Harley and Nightwing.

* ComfortTheDying: In one scene [[spoiler: Dr. Goldblum]] is mortally wounded and trying to tell the heroes about Poison Ivy and Floronic Man's plot. [[PetTheDog Harley holds his hand and tells him when he gets to Heaven he should talk to her grandmother, as she thinks he'll like her.]]

* ContinuitySnarl: When exactly the film is set in uncertain. In particular, there some evidence to suggest it takes place ''before'' the [[spoiler: Tim Drake incident in ''WesternAnimation/ReturnOfTheJoker]]. The problem being: if that's the case it would mean Harley [[spoiler:redeemed herself, and got the life she had always wanted, only to throw it all away and go back to being a villain just a few years later.]] For obvious reasons, this makes little sense.[[note]] Tie-in comics to the DCAU and especially to "Batman Beyond" attempt to suggest what is depicted in "Return of the Joker" to be a timeline that's been averted, and now alternate timelines and futures have replaced them, as depicted in later "Beyond" and DCAU comics.[[/note]]

* CuttingTheKnot: [[spoiler: Floronic Man has high resistance and is unaffected by bullets. Harley points out that they could just set him on fire.]]

* EarnYourHappyEnding: [[spoiler: Harley more or less goes straight, and in the post credits scene, has gone back to being Dr. Harleen Quinzel and has her own TV show.]]

** Then [[spoiler:Swamp Thing]] makes his grand entrance, reducing Jason to a cowering mess. [[spoiler: Swamp Thing]] tells Jason that what he's doing is wrong, but says it's not his right to stop it and [[spoiler: Swamp Thing]] disappears without lifting a finger. Lampshaded by Harley:

* JerkWithAHeartOfGold: The "redeemed" Harley is still an obnoxious bitch most of the time. She' still turns out to be basically a good guy, even though [[spoiler: she seems to double-cross Batman and Nightwing, it's just a trick as she saves them again right after.]]

* StatingTheSimpleSolution: While Batman and Nightwing are discussing what to do about Woodrew since none of their high tech weapons work on him, Harley [[spoiler: says that since he's a plant, they could just set him on fire.]] It works.

* WorstAid: Averted. When [[spoiler: Harold is impaled by Jason]] Batman says not to pull out the spike in his chest since that would just lead to more bleeding. [[spoiler: Harold still dies though.]]

* YouHaveOutlivedYourUsefulness: [[spoiler: Harold, who The Floronic Man kills the moment he perfects his formula]].

* PsychopathicWomanchild: Harley, as usual. She's not as psycho as before but still has a very childish demeanor. [[spoiler: she gets better at the end.]]
* PuppyDogEyes: [[spoiler:Harley pulls this (and CryCute) on Ivy to attempt to convince her to quit working with the Floronic Man. It works.]]

* AlternateUniverse: Averted, in this case. Bruce Timm had previously gone on record prior to its release to declare that this movie is part of the DCAU continuity, (albeit with [[https://www.youtube.com/watch?v=gn3yml1__Pk minor continuity issues]]). With the art style heavily leaning towards that of ''The New Batman Adventures'' and all the cameos that showed up in the villains' club scene, it is clear that he does intend this to be part of the DCAU.

*** It has also several minor characters from ''WesternAnimation/BatmanTheAnimatedSeries'', mostly of them minor villains or henchmen of the main villains of the series: Min and Max, [[UnexplainedRecovery the twins that worked for Harvey Dent and were killed by Rupert Thorne]] at the end of "Two-Face" part 2; Farmer Brown's genetically modified daughter Emmy Lou; Selina Kyle's assistant Mavin; Rocco and Henshaw, Joker henchmen; Crocker from "Appointment in Crime Alley"; Driller, a safe-cracking thug from the episode "POV"; Joker's henchmen from "Beware The Creeper"; Roland Daggett's henchman Germs; Scarface's henchman Rhino; Lily and Violet from "Eternal Youth"; Enrique El Gancho (Ricky the Hook); Nitro; a Calendar Boy; Ratso from "Read My Lips"; Candace (a minor villain who worked for Rupert Thorne, and Bane, and Two-Face); Mr. Freeze's henchgirls, the Moles, from "Cold Comfort"; Penguin's Iceberg Lounge waitress from "The Ultimate Thrill"; Captain Clown (a robot) from "The Last Laugh", and Randa Duane from "Heart of Steel", parts 1 and 2; Maven, Selina Kyle's assistant from "The Cat and the Claw". And, for some inexplicable reason, [[AndZoidberg Ra's Al Ghul's bodyguard Ubu.]] Felix and Leo, two of Catwoman's henchmen from the 60s Batman, also do the Batusi.

* RomanticTwoGirlFriendship: PlayedWith, Harley and Ivy both care a lot about each other and a lot of their motivations and actions are fueled by their feelings for one another. That said though they end up having a pretty brutal fight in the climax. But Ivy is finally convinced to turn on Floronic Man when Harley gives her PuppyDogEyes. Then, when Floronic Man sees this, he describes Harley as Ivy's 'mate'.
-->'''Ivy''': ''(Hugging Harley and crying)'' [[VitriolicBestBuds I hate you so much]].

* RealityEnsues: Nightwing expresses disappointment that Harley is working at a sleazy place like Superbabes and points out that Harley could have used her psychiatric training to get better work. After she ties him up in her apartment, Harley informs Nightwing that she did try to get more respectable jobs, but her criminal background prevented her from being hired, and her only options besides the restaurant were in pornography.

* CuttingTheKnot: [[spoiler: Floronic Man has high resistances and is unaffected by bullets. Harley points out that they could just set him on fire.]]

* AlternateUniverse: Averted, in this case. [[WordOfGod Bruce Timm]] had previously gone on record prior to its release to declare that this movie is part of the DCAU continuity, (albeit with [[https://www.youtube.com/watch?v=gn3yml1__Pk minor continuity issues]]). With the art style heavily leaning towards that of ''The New Batman Adventures'' and all the cameos that showed up in the villains' club scene, it is clear that he does intend this to be part of the DCAU.

* BreatherEpisode: For the DC Animated Films as a whole. After several DarkerAndEdgier films in the series such as ''WesternAnimation/BatmanTheKillingJoke'' and ''WesternAnimation/JusticeLeagueDark'', WordOfGod even said that they wanted ''Batman and Harley Quinn'' to be more light-hearted.

* TheComicallySerious: As per tradition, any time that Batman interacts with Harley Quinn. If anything, he takes it UpToEleven in this film, as even in the face of such things as Nightwing and Harley in a tickle fight, flatulence filling the Batmobile, and a drunken thug ''mockingly Batusi-ing at him,'' Batman steadfastly refuses to engage with anyone's silliness.

* FakeStatic: Batman has Nightwing crinkle some paper next to the microphone to fake the sound of static when [[TheScrappy Booster Gold]] calls them suggesting other available superheroes to assist them and wanting to join them himself. He's not fooled.

* SchrodingersCanon: When fans asked Bruce Timm if the film was canon to the DCAU, [[WordOfGod he said he thought it was but that it was ultimately not his choice to make.]]

* TheGhost: A conversation between Batman and Sarge Steel confirms the existence of ComicBook/LadyShiva in the DCAU and a later one between him and ComicBook/BoosterGold similarly reveals the existence of Bloodwynd, Black Condor, and Triumph. The Superbabes scene also suggests the existence of ComicBook/{{Starfire}} and -- despite Galatea being an expy of her -- ComicBook/PowerGirl.

* TheComicallySerious: As per tradition, any time that Batman interacts with Harley Quinn.

* AdaptationalJerkass: Weirdly zig-zagged with Harley. While she's no longer a villain and sincerely trying to reform here, she's also much less pleasant as a person than the ''Animated Series'' version, who always comes across as kind of sweet and childlike, while ''this'' Harley is rude and obnoxious 90 percent of the time.

** In a SuspiciouslySimilarSong and no-DC example, Harley's song in the henchmen bar sounds like Music/{{Blondie}}'s "Hanging on the Telephone".

A movie in the WesternAnimation/DCUniverseAnimatedOriginalMovies line, ''Batman and Harley Quinn'' is an original story created by Creator/BruceTimm. It's about ComicBook/HarleyQuinn teaming up with Franchise/{{Batman}} against ComicBook/PoisonIvy and Jason Woodrue. It stars Creator/KevinConroy as Batman, Creator/LorenLester as Nightwing, [[Series/TheBigBangTheory Melissa Rauch]] as Harley Quinn, Creator/PagetBrewster as Poison Ivy, and Creator/KevinMichaelRichardson as Jason Woodrue. It uses the same animation style as ''[[WesternAnimation/BatmanTheAnimatedSeries The New Batman Adventures]]'', and Bruce Timm treated this story as part of the Franchise/DCAnimatedUniverse continuity.

* YouWouldMakeAGreatModel: Apparently, Harley received many proposals to be in adult movies or shoots, since no hospital would ever accept a former supervillain.

-->'''Old man:''' [[GettingCrapPastTheRadar Sheee had... the cutest smile.]]

* InsistentTerminology: When Batman calls Harley a psychopath, she insists she's a sociopath instead.(In truth she is neither, as while she's mentally ill she can feel things like compassion and remorse, something real sociopaths don't do.)

* NoodleIncident: As mentioned under "The Ghost", Lady Shiva exists in this universe, but all we know from that seen is that she retains her ties to the League of Assassins and was involved in a battle in Nanda Parbat that brought her into conflict Batman and A.R.G.U.S.

* TheGhost: A conversation between Batman and Sarge Steel confirms the existence of ComicBook/LadyShiva in the DCAU and a later one between him and ComicBook/BoosterGold similarly reveals the existence of Bloodwynd, Black Condor, and Triumph.
