Basically, when you throw many characters belonging to a specific genre (or sometimes a distinct division of this genre -- e.g., the works of a certain author) into a MassiveMultiplayerCrossover, for the purpose of exploring and [[{{Deconstruction}} deconstructing]] -- and sometimes [[{{Reconstruction}} reconstructing]] -- said genre from a modern viewpoint (which may or may not be DarkerAndEdgier). It could use the actual characters and settings from said works, [[DoppelgangerCrossover or it could limit itself to using]] [[{{Expy}} Expies]] if said work isn't quite in the public domain (less common online, because [[FairUse copyrights matter somewhat less when no money changes hands]]).

Note that the MassiveMultiplayerCrossover itself here is just ''the means'', while ''the goal'' is the aforementioned genre exploration/deconstruction. Also note that it's only ''one'' of the possible uses for a MassiveMultiplayerCrossover, which may be implemented for numerous other purposes (e.g., [[RuleOfFunny fun]], [[RuleOfCool awesomeness]], [[{{Rule34}} sex appeal]], etc.).

A subtrope of MassiveMultiplayerCrossover, {{Deconstruction}} and sometimes {{Reconstruction}}. FanFic versions should also be placed under the DeconstructionFic trope.

* ''ViolenceJack'' has dark, twisted versions of many a GoNagai character. Considering what most of Go Nagai's characters are like to ''begin'' with...

[[folder:Comic Books]]
* Creator/AlanMoore ''loves'' this trope.
** ''ComicBook/LeagueOfExtraordinaryGentlemen Vols. 1 & 2'' did this with Victorian literaturem ''Black Dossier'' the sequel to did this with mostly 1950s British literature, and ''Vo1 . 3'' did this with early 20th century, 1960s and 1990s-2000s fiction. It's very likely that it was this graphic novel that influenced this trope's popularity in the last decade (especially in comics), so it's probably the TropeCodifier. Note that in the movie version a similar Massive Multiplayer Crossover is made mostly for RuleOfFunny and RuleOfCool, rather than {{Deconstruction}}. Thus, it's not an example of Deconstruction Crossover.
** ''ComicBook/{{Albion}}'' (created with Creator/AlanMoore's assistance) did this with 1950s-'70s British comics published by IPC.
** In ''Twilight of the Superheroes'', a script submitted by Alan Moore to DC, he wanted to do the same with the DC Universe.
** The original script for ''ComicBook/{{Watchmen}}'' was this: a crossover of several Charlton Comics characters intended for deconstructing the superhero genre from a modern viewpoint. The final work uses {{Captain Ersatz}}es of the Charlton characters instead.
** ''Comicbook/LostGirls'', with art by Melinda Gebbie, crosses the stories of ''Literature/AliceInWonderland'', ''PeterPan'' and ''Literature/TheWonderfulWizardOfOz''. The deconstructive part comes where instead of fantasy tales, they're all converted into similar stories of sexual awakening, often taking place when the girls are quite young [[spoiler:and sometimes with [[ParentalIncest family members]]]].
** The [[YoungbloodJudgmentDay ''Judgement Day'']] crossover Moore wrote for Awesome was this in spades, creating an enormous history for the Awesome universe apparently populated entirely by the CaptainErsatz novelty assortment.
* ''Comicbook/TheSandman'' does this with every comics, mythological or historical figure Neil Gaiman could work into the story.
* ''Comicbook/KingdomCome'': To some extent, it actually fulfilled the idea of ''Twilight of the Superheroes''.
** Basically, it starts with the idea "everything ever produced for DCComics was canon". All of it, ComicBook/{{Watchmen}}, VertigoComics, the [[TheBronzeAgeOfComicBooks experimental comics of]] TheSeventies, One shot characters from anthology comics, the SuperFriends Cartoon, all of it. Then, it took all the [[TheDarkAgeOfComicBooks contemporary trends in comics]], morally questionable storylines, BadAss [[NinetiesAntiHero Nineties Anti Heroes]], heroes and villains being [[AntiHeroSubstitute replaced]] with DarkerAndEdgier [[LegacyCharacter Legacy Characters]], and extrapolate them to their logical extremes. Then it took the [[TheGoldenAgeOfComicBooks Golden Age]] Generation of superheroes, and brought their powers to logical extremes, added biblical themes, and gave it to us in a photo-realistic "painted" style to make it more realistic, and disturbing. It certainly counts.
* ''{{Planetary}}'' did this with various fiction characters and genres. Most of the characters there are pastiches or {{Captain Ersatz}}s, and most genres are deconstructed in self-containing stories, regardless of the series' MassiveMultiplayerCrossover premise.
* J.Michael Straszynski's unfinished series ''TheTwelve'' did this with [[ExactlyWhatItSaysOnTheTin twelve]] various WWII-era Timely Comics superheroes, exploring the differences between modern and 1940s culture.
* ''Comicbook/{{Fables}}'' does this with fairy-tales and nursery rhymes.
* ''Comicbook/{{Twilight}}'', by Creator/HowardChaykin, did this with DCComics' [[TheSilverAgeOfComicBooks Silver Age]] science fiction characters. No relation to ''Twilight of the Superheroes''. Or [[Literature/{{Twilight}} that book with sparkling vampires.]]
* The {{JLA-Avengers}} miniseries. The plot of the series was all about the differences between the MarvelUniverse and TheDCU. Compared to the DCU, Marvel is a CrapsackWorld, and compared to Marvel, DC heroes are just [[SelfDemonstrating/TheJoker one bad day]] away from BewareTheSuperman.
[[/folder]]

[[folder:Fan Fic]]
* ''[[http://www.bladeandepsilon.com/hybridtheory.htm Hybrid Theory]]'' by Blade and Epsilon does this for the classic anime MegaCrossover and SelfInsertFic.
* ''FanFic/ADarkKnightOverSinCity'' explores the similarities and differences between the two comic franchises.
* ''Fanfic/MightyMorphinMechaRangers'' is a DeconstructiveParody crossover between lots of mecha anime (pretty much in the style of ''VideoGame/SuperRobotWars''), where the own tag says "This was either an awesome or a really bad idea!" the city that they supposedly have to protect clearly gets the second option.
* ''[[http://www.fanfiction.net/s/8116027/1/Fantasy-of-Utter-Ridiculousness Fantasy of Utter Ridiculousness]]'' can be considered a deconstruction of the FandomSpecificPlot of Yukari sending an outsider to Gensokyo. When the said outsider is [[WesternAnimation/MegasXLR Coop]], the girls are begging for him to leave.
* ''Fanfic/SleepingWithTheGirls'' brutally deconstructs the SelfInsertFic by demonstrating just what would happen if a person from the real world got sent to various anime worlds, but the rules of the real world applied to that person. It also demonstrates why having a GenreSavvy person from the real world in an anime world may not be the best thing for said anime world.
* Fanfic/BetweenMyBrotherAndMe: The characters aren't getting along, and are not opening up to each other (Yugi and the others don't tell about Battle City, May and Max can't tell about Atem and his past), Pokemon are being subjected to monsters and power far worse than Team Rocket can do to them, and the characters are dealing with a world that will literally kill them without guilt.
* ''{{Zulu Squad No Tsukaima}}'' [[https://www.fanfiction.net/s/10019351/1/Zulu-Squad-No-Tsukaima]] is a deconstruction of the {{Familiar of Zero}} crossovers in that the OC does not become Louise's familiar. Appropriate since the OC is an {{elite mook}} from {{Spec Ops The Line}}, which is a deconstruction of the military {{first person shooter}}.
* ''Fanfic/ChildrenOfTime''. The first season deals alternately subtly and heavily with the blood on [[Series/DoctorWho the Doctor's]] hands, and the BigBad deconstructs him thoroughly every chance he gets. Literature/SherlockHolmes as a Companion starts out well... and then his own caring, protective nature is turned against him, his need for control is played like his violin, and what he turns into shows just how far wrong a Companion can go. ThePowerOfLove and ThePowerOfFriendship are played against the heroes in some truly terrifying ways... And then [[EverybodyLives it all gets healed]] if not quite Reconstructed in the end.
* ''Fanfic/NoChanceForFate'' is a serious deconstruction of not only the FukuFic but also of the source material ''Manga/RanmaOneHalf'' and ''Anime/SailorMoon''. The standard plots for this kind of crossover are either either outright averted or subverted, often mixed with lampshade hanging or snarky mocking. The absurd plot points of the source material are dissolved in RealityEnsues and of course add more snarking. Yet, all this manages to show the true strength of the heroes, who still fight for the right cause.
* The ''FanFic/CodeMarsTrilogy'' is this for ''Anime/SailorMoon'' in the world of ''Anime/CodeGeass''. The former is usually stuck with BlackAndWhiteMorality and are screwed up when choosing between the oppressive [[TheEmpire Brittanians]] and [[YourTerroristsAreOurFreedomFighters the Black Knights.]] Adding to this is how the Black Knights are an [[DarkIsNotEvil exception]] to the DarkIsEvil [[LightIsNotGood and]] LightIsGood tropes. Moreover, they're in a world of HumongousMecha instead of normal supernatural monsters. Unless the shots are well-placed, Knightmare Frames NoSell the Scouts attacks.
** In the course of the story, the Scouts [[DeconReconSwitch get over this.]] They start in episodes 19 and 20 by showing their true selves and joining the Black Knights, accepting the DarkIsNotEvil trope. This is supported with incidents like the [[spoiler: SAZ Massacre]] and when an actual ''Sailor Moon''-like villain comes in to side with Britannia. Bonus points when they [[spoiler: get their AceCustom Knightmares]], and encounter phantom-like {{Mooks}}, allowing them to fiht enemies on the ground and against the [[MookMobile Mook Mobiles]].
* ''FanFic/AbigailAndTheRatsOfNIMH'' brings together characters from ''WesternAnimation/TheSecretOfNIMH'', ''WesternAnimation/OnceUponAForest'', ''Disney/TheRescuers'' and ''WesternAnimation/ChipNDaleRescueRangers'' and deconstructs the MouseWorld trope, exploring what would really happen if the oblivious humans in these kinds of stories actually started to notice the civilized rodents living among them. Naturally, NIMH becomes very interested.
[[/folder]]


[[folder:Films -- Animated]]
* ''Disney/WreckItRalph'' does this for VideoGames by having a PunchClockVillain from a 1980s-era game [[DudeWheresMyRespect get sick of being treated like dirt by the other characters from his game]], and decide to sneak into a FirstPersonShooter to earn a medal. HilarityEnsues, and this being a Disney film, ends up triggering an even bigger adventure for himself and others.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/WhoFramedRogerRabbit'' did this with {{Toon}}s. The original novel, ''WhoCensoredRogerRabbit'' was even DarkerAndEdgier and did it with newspaper comic strip characters instead.
* ''MurderByDeath'' did this with mysteries.
[[/folder]]

[[folder:Literature]]
* The novel [[http://en.wikipedia.org/wiki/Silverlock Silverlock]] contains characters and settings from Beowulf, Don Quixote, and countless others.
* Jonathan Swift wrote the satirical tract [[http://en.wikipedia.org/wiki/Tale_of_a_Tub A Tale of a Tub]] in 1694. It does this with {{Anthropomorphic Personification}}s of different sects of Christianity, deconstructing what Swift saw as the "flaws" in each.
* The Creator/NeilGaiman novel ''Literature/AmericanGods'' does this, along with a healthy dose of AllMythsAreTrue.
* This trope, combined with the LiteraryAgentHypothesis, is the main premise of many works taking place in Creator/PhilipJoseFarmer's Wold Newton Universe.
* The ''Literature/AnnoDracula'' series by Creator/KimNewman is a massive hodgepodge of characters vampire and non-vampire, fictional and non-fictional, Victorian and modern, running around in a world where Dracula killed Van Helsing and took over Britain.
* As previously stated, ''WhoCensoredRogerRabbit'' by Creator/GaryWolf.
* ''NurseryCrime'' by JasperFforde does this with nursery rhyme and fairy tale characters, to the point of postulating an entire murder mystery story around the age-old question of, "Why are the Three Bears' bowls of porridge different temperatures if clearly they were poured at the same time?"
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/OnceUponATime,'' for fairy tales in general and the Disneyfied versions in particular. Many of the episodes are from the POV of the Evil Queen from "Snow White and the Seven Dwarfs."[[/folder]]

[[folder:Theater]]
* ''IntoTheWoods'', containing characters from multiple fairy tales and weaving their stories together. The whole thing is deconstructed in the second act.
[[/folder]]

[[folder:Video Games]]
* There are some surprisingly convincing EpilepticTrees that interpret ''SuperSmashBrosBrawl'' as this. One theory states that Master Hand represents the forces of video game order (the rules by which video games function), Crazy Hand represents the forces of video game chaos (the unpredictability that makes video games fun), and [[spoiler:Tabuu represents the forces of SeriousBusiness and StopHavingFunGuys, what with his efforts to imprison Master Hand and destroy the world of video games]].
* ''VideoGame/SuperRobotWars'' games can turn into this to some degree, by showing how characters from one anime would react when facing plot and characters from others - friendships ([[GurrenLagann Kamina]] and [[GetterRobo Ryoma]] in [[VideoGame/SuperRobotWarsZ Z2]]) and rivalries ([[GGundam Domon]] and [[{{Daimos}} Kazuya]] in [[VideoGame/SuperRobotWarsMX MX]]) are formed, some characters turns different that in their source material ([[Anime/NeonGenesisEvangelion Shinji]] and [[GundamSEEDDestiny Shinn]], very often), some events are averted, villains fight one another ([[GaoGaiGar Zonderians]] vs [[Anime/TekkamanBlade Radam]] vs [[DetonatorOrgun Evolouders]] vs [[GaoGaiGar Eleven Lords Of Sol]] in [[VideoGame/SuperRobotWarsW W]]) or form alliances ([[{{Mazinkaiser}} Doctor Hell]], [[Lightnovel/FullMetalPanic Gauron]] and [[{{Zeorymer}} Hakkeshu]] in [[VideoGame/SuperRobotWarsJudgment J]]), not to mention characters making comments about events from other series.
-->'''[[CharsCounterattack Char Aznable]]:''' Your way will never bring true peace.
-->'''[[GetterRobo Ryoma Nagare]]:''' [[ColonyDrop And dropping a rock]] [[ShutUpHannibal on Earth will]]?
** ''VideoGame/SuperRobotWarsZ'' goes one step further by actually having some characters show in multiple versions of their animated continuities, in order to contrast the differences between them. For example, Classic Ryoma witnesses Armageddon Ryoma and is horrified by his much more violent nature.
[[/folder]]

[[folder:Web Comics]]
* ''BreakfastOfTheGods'' does this with breakfast cereal mascots.
* Most of Bleedman's {{Webcomics}} (e.g., ''PowerpuffGirlsDoujinshi'', ''FanFic/GrimTalesFromDownBelow'') do this with various WesternAnimation cartoons (at the same time changing their drawing styles to an {{Animesque}} one).
** And then ''FusionFall'' used that concept as well, retaining the Massive Multiplayer Crossover and the change to an {{Animesque}} style, but dropping any hints to {{Deconstruction}}.
* ''Webcomic/KidRadd'' seems to do this, but featuring {{Captain Ersatz}}es and pastiches rather than actual trandemarked VideoGame characters.
** It has it's own in universe versions of games like ''SuperMarioBros'', ''VideoGame/EarthBound'', ''FinalFantasy'', and even ''Deadly Towers'' and cheesy flash games. It really does well at showing what a character from one genre of games would look like if he was forced into a completely different genre but his character still followed the rules of his original game. For example, how would a platformer character for whom everything does equal damage, and only has four slots in his health bar deal with being put in an RPG where every character has thousands of HP? How would a fighting game character, who needs to take advantage of a character being temporarily stunned after being hit in order to perform combos deal with a platformer character who becomes temporarily invincible after being hit?
* ''CaptainSNES'' fits into this category fairly well. Not only are many of the villains aware that they are merely video game characters (which is, in at least one case, [[GoMadFromTheRevelation why they became villains to begin with]]), but characters who travel from one video game world to another are not always prepared for the different rules. (The [[http://www.captainsnes.com/2002/10/26/219-the-ways-of-the-mushroom/ comic]] where [[VideoGame/ChronoTrigger Magus]] writes of his experiences learning from [[SuperMarioBrothers Mario]] seems a good illustration of this.)
* [[http://sire.thewebcomic.com/ Sire]] is a comic about the ancestors of literary characters reliving their "Sire"s story and having to take cues and morals from the original work as not to earn a tragic ending. Rare as the characters are aware of the trope and use the deconstruction as a means to survive.
[[/folder]]

[[folder:Web Original]]
* ''ThereWillBeBrawl'' straddles the line of this and a a DarkerAndEdgier {{Parody}} of Creator/{{Nintendo}} [[VideoGames games]]. It uses a pre-existing Massive Multiplayer Crossover established by the ''VideoGame/SuperSmashBros'' franchise, and then constructs a world based around the end result of innocent and not-so-innocent characters fighting a purposeless war against each other for years.
* The [[http://www.newgrounds.com/collection/finalfightingfantasy Final Fighting Fantasy]] Flash series on NewGrounds does a good job at this. For the various FinalFantasy Characters, it starts off as what looks like a simple poorly written fan fic, but quickly [[GrowingTheBeard grows the beard]] and becomes quite epic.\\
It turns out that the [[InfinityPlusOneSword legendary weapons]] of the games where created by the ancients as a way of manipulating the game's protagonists into defeating the forces of evil, and thus restoring balance, however, after evil was defeated, the good guys can't stay around any longer, because they would tip the balance to far towards the light, so, the weapons transport them to another world, where they all meet each other, and (because of the influence the weapons have on their mind) convince them that the characters from the other games are evil, and thus they're forced into a fight to the death. The different characters named "Cid" that appear in every game is actually the same guy, manipulating things from behind the scenes. Unfortunately, FinalFightingFantasy has [[DeadFic been left unfinished]]
* ''Webcomic/CheshireCrossing''. Three girls believed to be insane are all sent to a new place. A 'boarding school'. But the three girls are [[Literature/AliceInWonderland Alice Liddell]], [[PeterPan Wendy Darling]], and [[Film/TheWizardOfOz Dorothy Gale]]. And the 'teacher' is Film/MaryPoppins. Has to be read, because it's definitely better than it sounds.
* MarvelDCAfterHours does this. Season 1 questions the validity of Franchise/{{Superman}}, Season 2 deals with what the heroes would be like if they all went through what Franchise/{{Batman}} did, and Season 3 revolves around the concept of the ContinuityReboot, and what it would be like to go through one. By the end, it is always ReConstructed.
[[/folder]]

[[folder:Western Animation]]
* Most of the humor in ''WesternAnimation/RobotChicken'' comes from this. For example, there's ''WesternAnimation/BeavisAndButthead'' join the ''WesternAnimation/TeenTitans'', and ''{{MTV}} Exposed'' on {{Franchise/Barbie}} and {{Bratz}}. Of course this is used mostly for [[DeconstructiveParody comedic purposes]].
* The point of ''WesternAnimation/DrawnTogether'' was to be like this, they took [[CaptainErsatz Captain Ersatzes]] of Comicbook/{{Superman}} (Captain Hero), [[Franchise/{{Pokemon}} Pikachu]] (Ling Ling), [[Franchise/TheLegendOfZelda Link]] (Xandir), BettyBoop (Toot), JosieAndThePussycats (Foxxy), the {{Disney Princess}}es (Clara), WesternAnimation/SpongeBobSquarePants (Wooldoor) and vulgar flash cartoons (Spanky) and put them in one house as a Parody of every RealityShow ever made. Unfortunately it [[SeasonalRot quickly devolved]] into [[BlackComedy dead baby humor]].
* ''WesternAnimation/TheVentureBrothers''. The Monarch is a deconstruction all the Campy Supervillians of TheSixties. Brock Sampson was something of a deconstruction of every ActionHero ever made, The Titular brothers themselves are a deconstruction of ''TheHardyBoys'' and ''JonnyQuest''. They also turned the gang from ''WesternAnimation/ScoobyDoo'' into a UsefulNotes/MansonFamily-type collection of [[TheSixties 60s]] and [[TheSeventies 70s]] era [[SerialKiller Serial Killers]]. They also have a rather interesting take on Comicbook/FantasticFour
* ''WesternAnimation/TurtlesForever'' has the Franchise/TeenageMutantNinjaTurtles from [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 cartoon]], the Turtles from [[WesternAnimation/TeenageMutantNinjaTurtles2003 the 2000s cartoon]] and the Turtles from [[Comicbook/TeenageMutantNinjaTurtlesMirage the Mirage comics]] meet. To clarify how well this actually works as a deconstructive crossover, the antics and personalities of the '80s Turtles--somewhat exaggerated but still grounded in the source material--annoy, confound, and irritate the 2003 turtles to no end. Even Michelangelo, eventually. Then they meet the original Mirage turtles (as written in issue 1), and even the 2003 guys seem like plushies by comparison. Yet, in the end, all versions of the Turtles are deemed just as valid as the others.
** It's been complained that the 1987 Turtles seem more cowardly. Of course they are; they're in a different world where they are not the main characters, the fourth wall is more rigidly in place, and the BigBad is both ruthless and competent. Goodbye, PlotArmor.
