11* ''Fanfic/OneHundredOneWaysToKillJarJarBinks'' has fictional characters from various horror franchises killing Jar-Jar Binks from the Star Wars prequel trilogy.
12* ''Fanfic/AIsA'' uses [[Series/StargateSG1 Stargate Command]] as the vehicle to launch into the multiverse, including [[Manga/FairyTail wizards]], [[WesternAnimation/TheLegendOfKorra benders]] [[VideoGame/CommandAndConquerTiberianSeries commandos]], and [[WesternAnimation/MyLittlePonyEquestriaGirls teenagers]].
13* ''Fanfic/AbigailAndTheRatsOfNIMH'' combines several 80's and 90's MouseWorld cartoons (''WesternAnimation/OnceUponAForest'', ''WesternAnimation/TheSecretOfNIMH'', ''WesternAnimation/ChipNDaleRescueRangers'', and ''WesternAnimation/TheRescuers''), which could at least in theory take place in a shared universe, with a little imagination. The adventure starts when scientists from NIMH, in search of the intelligent rats that escaped from their labs years ago, raid Dapplewood forest (the setting of ''Once Upon a Forest''), and the story develops into a CrisisCrossover as the scientists become more aware of the mouse civilization that's been right under their noses.
14* ''FanFic/AdoptedDisplaced'' is about various ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' characters getting sent different universes and being adpoted by characters from those worlds. Universes include ''VideoGame/TeamFortress2'', ''Franchise/RatchetAndClank'', ''Franchise/SamAndMax'', ''VideoGame/GodOfWar'', ''VideoGame/DevilMayCry'', ''Franchise/DCAnimatedUniverse'', ''ComicBook/IronMan'', ''Franchise/{{Metroid}}'', ''ComicBook/{{Deadpool}}'', ''WesternAnimation/WreckItRalph'', ''VideoGame/MegaManClassic'' and ''VideoGame/MegaManX'', ''Franchise/AvatarTheLastAirbender'', ''VideoGame/JakAndDaxter'', ''WesternAnimation/JackieChanAdventures'', ''VideoGame/SlyCooper'', ''Franchise/TheElderScrolls'', ''VideoGame/{{Portal}}'', ''VideoGame/{{Mother}}'', ''Franchise/StarFox'', ''WebAnimation/RedVsBlue'', and ''Franchise/DespicableMe''. Universes that are set to appear include ''Series/StarTrekTheNextGeneration'', ''VideoGame/FinalFantasyIV'', ''[[Literature/DirtyPair Dirty Pair Flash]]'', ''WebVideo/DragonBallZAbridged'', ''VideoGame/KidIcarus'', and possibly, ''WesternAnimation/GravityFalls'', ''VideoGame/{{Darkstalkers}}'', and ''WebVideo/SwordArtOnlineAbridged''.
15* ''[[http://aykfrpg.forumotion.net/forum.htm The Adventure You'd Kill For]]'' was a roleplaying forum thread game, in which fictional murderers (and a handful of legitimate soldiers) are imprisoned together by supernatural jailers and [[https://www.youtube.com/watch?v=eeqLGbjSpXA forced to work together in order to escape.]] Characters included are [[ComicBook/TheSandman the Corinthian]], [[Series/{{Heroes}} Sylar]], [[VideoGame/MetalGearSolid3SnakeEater the Fear, Naked Snake / Big Boss]], [[Franchise/AssassinsCreed Altair]], and [[Film/KillBill Beatrix Kiddo / The Bride]]. [[Webcomic/TheOrderOfTheStick Belkar Bitterleaf]], [[ComicBook/SinCity Dwight McCarthy]], [[ComicBook/JohnnyTheHomicidalManiac Johnny C.]], ComicBook/TheJoker, [[Franchise/ANightmareOnElmStreet Freddy Krueger]], Theatre/SweeneyTodd, [[Literature/TheLordOfTheRings Saruman the White]], [[Literature/TheSilenceOfTheLambs Hannibal Lecter]], [[Literature/HarryPotter Bellatrix Lestrange]], [[Franchise/TheWitcher Geralt of Rivia]], [[Film/TheTexasChainsawMassacre Leatherface]], and many more. However a lapse in activity for several years led to it becoming an OrphanedSeries.
16* ''Fanfic/AdventCrossoverCrisis'', found [[https://www.fanfiction.net/s/8731849/1/Advent-Crossover-Crisis here]], combines over 30 pieces of fiction, although it kinda depends on how you slice it.
17* ''[[http://murpg.proboards.com/index.cgi?board=ageofheroes Age of Heroes]]'' is a roleplaying campaign which starts with Marvel and DC which then crams in anything that can be fit in. ''Castlevania, Soul Calibur, Yu Yu Hakusho'', and more. Now it might seem that such a campaign would collapse under its own weight, but it seems to be doing quite well.
18* The ''Fanfic/AkaneNoMai'' franchise consisted of ''VideoGame/Persona5'', ''VideoGame/CodeVein'', ''VideoGame/{{Nioh}}'' and ''Manga/{{Kakegurui}}''. However, it downplayed this trope as it mainly focuses on ''Persona 5'' and ''Code Vein''.
19* ''Fanfic/AllWorldsAlliance'' written by [[https://www.fanfiction.net/u/8286539/someonestupED someonestupED]] is a series of fanfics stories which features an ensemble cast of characters that attends a place called the AWA Academy and at the same time, they go on adventures by traveling across the multiverse while fighting the forces of chaos.
20* ''Fanfic/AllStarWarzone'' is a massively compilation of fighting game movesets done for characters from...anything and everything. From games to literature, TV shows and webcomics...even notorious memes and people like Belle Delphine get sets of their own.
21* The title team of ''[[https://www.fanfiction.net/s/10709775/1/The-Amasing-Soopr-Teem THE AMASING SOOPR TEEM!]] includes ComicBook/SpiderMan, [[Franchise/TeenageMutantNinjaTurtles Splinter]], [[Franchise/{{Transformers}} Bumblebee]], Franchise/{{Godzilla}}, [[Film/TheWizardOfOz Dorothy Gale]], [[Franchise/DespicableMe the Minions]], and a flying "super puppy". And in one chapter they go to WesternAnimation/{{Ninjago}}. [[CrackFic If you think this sounds like something two little kids would make up]]... well, it is.
22* The ''Fanfic/AnimeXMarvel'' series revolves around various anime series having numerous elements from the ''Franchise/MarvelUniverse'' like the Franchise/MarvelCinematicUniverse Spider-Man entering the ''Literature/ReZero'' Universe, [[Manga/MyHeroAcademia Izuku Midoriya]] becoming WesternAnimation/{{Iron Man|ArmoredAdventures}}, [[Manga/{{Naruto}} Naruto Uzumaki]] becoming the apprentice of Film/{{Doctor Strange|2016}} or [[Manga/DemonSlayerKimetsuNoYaiba Tanjiro Kamado]] becoming the host to ComicBook/{{Venom}}.
23* The fanfic ''FanFic/AnotherWorld'' is a story about a boy (Or rather, the AuthorAvatar) that stranded on a world that is a big mashup of ''VideoGame/{{Terraria}}'', ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Franchise/{{Pokemon}}, Manga/BoboboboBobobo, Franchise/SonicTheHedgehog, Franchise/SuperMarioBros, Series/DoctorWho, and {{Webcomic/Homestuck}}.
24* Given the popularity of chat fics on Website/ArchiveOfOurOwn, it seems inevitable that they'd mix with this trope sooner or later. Examples include ''[[https://archiveofourown.org/works/12006930/chapters/27169158 Welcome to the Party Line!]]''[[note]]crossing over ''Franchise/Ben10'', ''WesternAnimation/DannyPhantom'', ''WesternAnimation/StarVsTheForcesOfEvil'', ''WesternAnimation/StevenUniverse'', ''WesternAnimation/PennZeroPartTimeHero'', ''WesternAnimation/{{Grossology}}'', ''WesternAnimation/MyLittlePonyEquestriaGirls'', and ''WesternAnimation/MiraculousLadybug''[[/note]] and ''[[https://archiveofourown.org/works/13197339/chapters/30188601 Send Read Receipts]]''[[note]] which crosses over the first four on the previous list, plus ''WesternAnimation/TheLifeAndTimesOfJuniperLee'', ''WesternAnimation/GravityFalls'', ''WesternAnimation/KimPossible'', ''WesternAnimation/GeneratorRex'', ''WesternAnimation/AmericanDragonJakeLong'', ''WesternAnimation/TheSecretSaturdays'', and ''WesternAnimation/ElTigreTheAdventuresOfMannyRivera''[[/note]].
25* ''[[https://www.fanfiction.net/s/992536/1/Arisugawa-s-Locket Arisugawa's Locket]]'' has a cast of "regulars" that includes characters from ''Anime/RevolutionaryGirlUtena'', ''Anime/SailorMoon'', ''Anime/TenchiMuyo'', ''Manga/ExcelSaga'', ''Anime/HandMaidMay'', ''Anime/TheVisionOfEscaflowne'', and ''Manga/RanmaOneHalf'', and that list gets longer as the story goes on. The "guest stars" can come from, well, pretty much anywhere in the anime world, and on rare occasions, a live action show like ''Series/BuffyTheVampireSlayer''. The rampant crossing over is explained by the fact that [[Anime/TenchiMuyo Washu]] equipped the titular bar with a version of her Time and Space device, allowing it to exist over multiple dimensions.
26* The ''FanFic/BattleFantasiaProject,'' where the nationally televised attempted suicide of a magical girl reveals the existence of magic to the world, and the existence of magical girls to eachother. Includes ''Anime/SailorMoon'', ''Franchise/LyricalNanoha'' (post-''A's''), ''Manga/CardcaptorSakura'', ''Literature/{{Kampfer}}'', ''Anime/PuellaMagiMadokaMagica'' ''all'' the ''[[Anime/PrettyCure Precures]]'' and others.
27* [[https://www.deviantart.com/bearquarter2008 Bearquarter2008]] has made a couple of them.
28** ''Bearquarter's Franchise/ToyStory'' trilogy stars [[WesternAnimation/MrPeabodyAndSherman Sherman Peabody]] as Sheriff Woody, [[WesternAnimation/JimmyNeutronBoyGenius Jimmy Neutron]] as Buzz Lightyear, Cindy Vortex as Jessie the Yodeling Cowgirl, Trent from ''WesternAnimation/TotalDrama'' as Andy, [[WesternAnimation/TheAmazingWorldOfGumball Gumball Watterson]] as Mr. Potato Head, [[Franchise/HowToTrainYourDragon Toothless]] as Rex, [[WesternAnimation/SpongeBobSquarePants Spongebob]] as Slinky, [[WesternAnimation/GravityFalls Mabel Pines]] as Bo Peep, Duncan as Sid, [[VideoGame/BackyardSports Vicki Kauaguchi]] as Bonnie, and has multiple characters in it as well.
29** Bearquarter2008 is currently planting the seeds for his Crossover Event, "The Ultimate Infinity War", inspired by [[Franchise/MarvelCinematicUniverse the Infinity Saga of the Marvel Cinematic Universe]]. His first fic, [[https://www.fanfiction.net/s/13164494/1/A-Hero-to-Look-Up-To A Hero to Look Up To]] is the Stage setter for the saga.
30* ''[[Fanfic/EyesOnMe Be Wherever You Are]]'' is, first and foremost, a ''WesternAnimation/StevenUniverse'' Human [=AU=] fanfic that also combines the likes of ''Manga/FullMetalAlchemist'', ''WesternAnimation/{{Arthur}}'', and ''WesternAnimation/SpongebobSquarepants''.
31* ''FanFic/BloodAndRevolution'' is, originally and nominally, a ''Manga/RurouniKenshin'' story. It blossoms until it includes 15 other series, most notably ''Manga/YuGiOh'', ''Manga/InuYasha'', and ''Manga/CardCaptorSakura''.
32* ''FanFic/BothSyllables'' combines ''WesternAnimation/InvaderZim'', ''Franchise/LiloAndStitch'', and ''WesternAnimation/BuzzLightyearOfStarCommand''.
33* ''Fanfic/TheBridge'' mixes together not just the titular Franchise/{{Godzilla}} and ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' series, but the world the kaiju characters come from is one huge amalgam timeline that includes ''Film/PacificRim'', Film/{{Gamera}}, ''Film/WarOfTheGargantuas'', ''Film/{{Cloverfield}}''; and nearly a dozen lesser known kaiju properties such as Yonggary and Raiga. Equestria also has pony versions of characters from ''Manga/SailorMoon''.
34* ''Fanfic/BridgesBurned'' uses this to offer [[WesternAnimation/MiraculousLadybug Marinette]] a form of payback against her classmates after they all [[FairWeatherFriend turn their backs on her]]. She starts by bringing [[Franchise/{{Superman}} Lois Lane]] by for a visit, exciting her former friend Alya, who idolizes her... only to introduce her to her friend ''Aurore'' instead. Creator/JJAbrams is the next to visit, and starts trying to recall Nino's name before she corrects him to Claude. One by one, she arranges for friends who ''didn't'' betray her to meet people her former friends idolize, both fictional and real-life figures, rewarding them with various life-changing opportunities, while those who betrayed her are forced to watch others live out their dreams.
35* The massive ''[[http://www.fanfiction.net/s/3587925 Chicago Convergence]]'' includes characters from ''[[Literature/MythAdventures Another Fine Myth]]'', ''Literature/{{Bolo}}'', ''Series/BuffyTheVampireSlayer'', ''Series/{{Charmed|1998}}'', ''Literature/CatchTwentyTwo'', ''Series/DarkAngel'', ''Series/DiagnosisMurder'', ''Series/DoctorWho'', ''Series/DueSouth'', ''Series/EarlyEdition'', ''Series/ForeverKnight'', ''Series/FridayThe13thTheSeries'', ''Literature/HammersSlammers'', ''Franchise/{{Highlander}}'', ''Franchise/IndianaJones'', ''Series/KnightRider'', ''Series/KungFuTheLegendContinues'', ''Literature/TheLordOfTheRings'', ''Series/SheWolfOfLondon'', ''Series/{{MacGyver|1985}}'', ''Series/MartialLaw'', ''VideoGame/MechWarrior'', ''Film/MenInBlack'', ''Series/MurderSheWrote'', ''Series/NashBridges'', ''Series/KolchakTheNightStalker'', ''Series/QuantumLeap'', ''Series/QuincyME'', ''Series/RelicHunter'', ''Series/SevenDays'', ''Series/{{Sliders}}'', ''Series/SpaceAboveAndBeyond'', ''Series/SpecialUnit2'', ''Series/StargateSG1'', ''Franchise/StarWars'', ''Film/TheTerminator'', ''Literature/TheBlackCompany'', ''ComicBook/TheIncredibleHulk'', ''Series/ThePretender'', ''Series/TheSentinel'', ''Film/TheWizardOfOz'', ''Film/TimeBandits'', ''Series/TheTimeTunnel'', ''WesternAnimation/TheTransformers'', ''Series/{{Viper}}'', ''Series/WalkerTexasRanger'', and ''Series/TheXFiles'' all coming to UsefulNotes/{{Chicago}}. It manages to stay both coherent and hilarious.
36* ''Fanfic/CardsOfRemnant'' is an odd example. It's only a crossover between ''Franchise/YuGiOh'' and ''WebAnimation/{{RWBY}}'', but the story includes elements from seemingly ''every'' Yu-Gi-Oh! series, even ones that were never directly connected in canon. Some ArcWelding is done to make them all fit together and fit within Remnant.
37** From ''[[Anime/YuGiOh Duel Monsters]]'': The Three Legendary Dragons exist on Remnant, with Ozpin possessing Timaeus, and Amber having possessed Hermos before Cinder stole it. Various creation myths likewise revolve around the Egyptian Gods.
38** From ''[[Anime/YuGiOhGX GX]]'': The Academies use the same student ranking system as Duel Academia, and [[spoiler:the Signer Dragons are heavily implied to be related to the Light of Destruction.]]
39** From ''[[Anime/YuGiOh5Ds 5D's]]'': The Signers and their associated Dragons exist here, with several members of Team STRQ being Signers, and Ruby herself possessing Aki's mark and Black Rose Dragon. Turbo Duels likewise exist, with both Yang and Pyrrha having D-Wheels, Yang's of course being Bumblebee. [[spoiler:Nora's mother meanwhile possessed a Rune-Eye, with Nora now in possession of Thor, Lord of the Aesir.]]
40** From ''[[Anime/YuGiOhZEXAL ZEXAL]]'': The Number cards exist in Remnant, with Pyrrha possessing Number 86 ''and'' [[spoiler:forging Number 101.]] Jaune meanwhile is a fan of the "Onomatopoeia Gang", based on Yuma's monsters, and [[spoiler:takes on Yuma's role by partnering with Astral.]]
41** From ''[[Anime/YuGiOhARCV ARC-V]]'': Pendulum monsters are highly favored by Faunus duelists, the White Fang even possessing a member known as the "Odd-Eyes Bandit" due to their usage of a Performapal deck [[spoiler:said duelist being Blake. The Four Dimensional Dragons also choose the members of Team RWBY to forge their cards, with Salem all but said to be desiring to revive Z-ARC.]]
42** From ''[[Anime/YuGiOhVRAINS VRAINS]]'': Atlas has pioneered Link Summoning, with Penny using Yusaku's deck, including Decode Talker and Cyberse Clock Dragon as her aces.
43* ''Fanfic/ChristianHumberReloaded'' includes quite a few franchises, including ''Anime/DragonBallZ'', ''Toys/{{Bionicle}}'', ''Franchise/FinalFantasy'', ''Franchise/KingdomHearts'', ''Manga/InuYasha'', ''VideoGame/StarCraft'' and more, typically by Vashblade visiting one of their worlds or acquiring a power featured in that series.
44* ''Fanfic/ChildOfTheStorm'' and its associated stories has ''Literature/HarryPotter'' and the ''Franchise/MarvelCinematicUniverse'' for a basis, but swiftly mixes in elements of various versions of the ''Franchise/MarvelUniverse'' and ''Franchise/DCUniverse'' including ''ComicBook/UltimateMarvel'', ''ComicBook/TheSandman'', ''WesternAnimation/XMenEvolution'', ''Film/XMenFilmSeries'', ''{{Series/Smallville}}'', ''Literature/TheDresdenFiles'', ''Series/StargateSG1,'' ''[[Series/Merlin2008 Merlin]],'' and elements of ''Literature/TheLordOfTheRings'' and ''Literature/OldKingdom ''(the latter two described InUniverse as fiction based on reality).
45** And during the finale of Book I, reality is crumbling, leading to a few cameos from characters that are explicitly fictional InUniverse, including [[spoiler: the 4th Doctor. [[SugarWiki/FunnyMoments Darcy promptly swipes his jelly-babies.]]]]
46** On top of all of this, it is ReferenceOverdosed, with shout outs galore to ''Series/DoctorWho'', ''{{Series/Torchwood}}'', ''Series/BuffyTheVampireSlayer'', ''Film/PacificRim'', ''Film/ThePrincessBride'' and many others abounding.
47* ''Fanfic/ChildrenOfTime'' is, first and foremost, a [[Series/DoctorWho Who]][[Literature/SherlockHolmes lock]] series, but, as befits the ''Who'' side of things, it incorporates more than just those two 'verses. ''WesternAnimation/SherlockHolmesInTheTwentySecondCentury'' eventually comes into play, providing us with the second season, Robin Hood makes guest appearances, and other 'verses are hinted at existing or are being saved up for future use.
48* ''Fanfic/CitadelOfTheHeart'' did ''[[SubvertedTrope not]]'' start off as one of these, but eventually evolved into it over time. Originally starting off as a re-imagining of ''VideoGame/PokemonBlackAndWhite'' with some elements of the anime, the first fic of the installments of ''Citadel Of The Heart'' is called ''Truth and Ideals''. Due to how everything got started off, ''Citadel Of The Heart'' is currently the name of both the entire Crossover Fic and a planned CrisisCrossover planned later down the road. So far the currently uploaded stories are based on ''Anime/DigimonAdventure'', ''Anime/DigimonTamers'', the aforementioned ''VideoGame/PokemonBlackAndWhite'', ''WesternAnimation/DinoSquad'', ''Literature/SwordArtOnline'', and ''WesternAnimation/CodeLyoko'', as well as having the author's original works being recycled and re-purposed for this giant continuity in the making, and so far also including small roles or cameos from future installments such as ''VideoGame/CustomRobo''[[note]](Ray 01 cameoing in ''Truth and Ideals'')[[/note]], ''WebAnimation/{{RWBY}}''[[note]](Grimm inspired Ultra Beasts appearing in the final arc of ''Truth and Ideals'')[[/note]], ''VideoGame/{{Rampage}}''[[note]](the three original monsters from the games appearing similar to their movie incarnations as special case mutations in ''[=DinoSquad RX=]'')[[/note]], and ''Franchise/KingdomHearts''[[note]](What the author, as well as some of his friends, have drawn comparisons between ''Citadel Of The Heart'' in regards to other MassiveMultiplayerCrossover media as a whole)[[/note]]. A work in progress list of further installments can be found under [[Timeline/CitadelOfTheHeart the fic's timeline page]].
49* ''Roleplay/CollectionQuest'' is gradually trucking toward this stage. Not only is Danny summoning characters from a number of worlds, but some very powerful beings from the various worlds are starting to notice when Vees pokes around their reality...
50* ''Fanfic/ComesACrossover'' is a mega parody of this trope. Various characters from all over culture, from anime, video games, comic books, and cartoons are all gathered together in the ''WesternAnimation/EquestriaGirls'' world due to the walls of reality being broken down by a magical artifact. Characters are introduced in each chapter due to the ridiculous situation and their interactions help drive the plot forward as they try to figure out a way to fix reality and put everyone back where they belong.
51* Due to TheMultiverse being so intertwined into the lore and story of ''Roleplay/{{Communication}}'', there are WAY TOO MANY franchises that are featured here to account for.
52* ''[[http://www.fanfiction.net/s/8383248/1/ Concept Road]]'' is an adventure spanning through many video game and anime universes with {{Shout Out}}s [[ReferenceOverdosed galore.]]
53** The strong point of the story seems to be the fact that the plot is written like an [[RolePlayingGame RPG]] complete with tutorial fights, [[SidequestSidestory side-quests]], [[RandomEncounters mob]] and {{boss battle}}s, {{NPC}}s and appropriate {{BGM}} if you’re willing to go through the ([[Website/YouTube actually simple]]) effort of opening them. (The [[http://archiveofourown.org/works/620663/chapters/1119976 AO3 version of the story]] has working hyperlinks).
54** ''[[Fanfic/ConceptRoad A more detailed description can be found here.]]''
55* ''[[http://lubakmetyk.infinology.net/others/bootleg/act1.html Convergence]]'' is another one, set on ''Series/BabylonFive'', from the late 90s. Politics and squabbling between the many authors eventually drove everyone away.
56* ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'' takes ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', mixes it with the [[spoiler: ''WesternAnimation/MyLittlePonyTVSpecials'']], as well as having [[spoiler:[[Series/{{Sherlock}} Mycroft Holmes]], [[Series/DoctorWho the Doctor]]]], and [[VideoGame/GrandTheftAutoV the crew of GTAV]] on the heroes' faction. Moreover, [[spoiler:Prime!Discord]] is also shown to be a DimensionalTraveler and uses the skills, weapons and likeness of the warriors he's met to help out the protagonists.
57** Its reboot, ''FanFic/{{SPECTRUM}}'', considerably dials down on the crossover aspect, preferring instead to intertwine the canon show and its supplemental materials along with the [[spoiler: ''WesternAnimation/MyLittlePonyTVSpecials'']].
58* ''Fanfic/CoreLine'' (a fanfiction and RPG setting). A computer virus has devastated the Earth. [[EarthIsABattlefield Earth is a multiversal battlefield]]. Real vs Fiction, canon vs. non-canon, various shows clashing against each other.
59* ''Fanfic/{{CRISIS|Thuktun}}'' is notable for mainly being a MassiveMultiplayerCrossover of {{Crossovers}}, with some unaltered franchises thrown into the fray. Franchises include ''Literature/{{Animorphs}}'', ''Anime/AttackOnTitan'', ''Franchise/{{Batman}}'', ''Film/{{Gamera}}'', ''Franchise/{{Godzilla}}'', ''Literature/FootFall'', ''Literature/KnownSpace'', ''Franchise/{{Superman}}'', ''TabletopGame/Warhammer40000'', and ''Literature/{{Worm}}'', to name some examples.
60* ''[[https://archiveofourown.org/series/1932643 Crossover Universe]]'' is a series on Website/ArchiveOfOurOwn that has characters from ''WesternAnimation/{{Arthur}}'', ''WesternAnimation/SpongeBobSquarePants'', ''Franchise/ScoobyDoo'', ''WesternAnimation/GravityFalls'', WesternAnimation/ClassicDisneyShorts, ''WesternAnimation/KimPossible'', ''WesternAnimation/RickAndMorty'', ''Franchise/KingdomHearts'', and more, with [[WesternAnimation/SamuraiJack Aku]] as the BigBad.
61* ''[[http://www.fanfiction.net/s/5032746 CrossWorld: Episode 1]]'', by Hejin57, a.k.a. Kareem Elamrani. Usually, a MassiveMultiplayerCrossover will contain either anime or WesternAnimation, but this is one of the few exceptions. Crossworlds is an unfinished work containing, so far, characters from ''WesternAnimation/DextersLaboratory'', ''WesternAnimation/CodenameKidsNextDoor'', ''Franchise/SonicTheHedgehog'', ''WesternAnimation/TheNightmareBeforeChristmas'', ''WesternAnimation/ThePowerpuffGirls'', ''WesternAnimation/SamuraiJack'', and, of all things, ''Literature/HaruhiSuzumiya''. It's about as {{crack|Fic}}y of an idea as one would expect.
62** The same author has also written ''[[http://www.fanfiction.net/s/5576875 Cross Chronicles]]'', a more conventional MassiveMultiplayerCrossover of ''Literature/HaruhiSuzumiya'', ''Manga/KenichiTheMightiestDisciple'', ''Anime/TengenToppaGurrenLagann'', ''Manga/MidoriDays'', and ''VisualNovel/FateStayNight''. What's more, the fanfic itself is set in the universe of ''VideoGame/ValkyriaChronicles''. Interestingly enough, even though the two fics are completely different, the same PlotDevice is used to get all the different fandoms together in both of Hejin's {{Massive Multiplayer Crossover}}s.
63* ''FanFic/CrownsOfTheKingdom'' is this for many, many Disney characters and all of the areas of Disneyland.
64* ''Fanfic/DairantouSaintZearth'' is really shaping up to be one, [[JustifiedTrope Justified by a Rule of the Author's]] which states that any work of Fiction caught with a Trope Page is fair game to be added. Not including main components heirlooms and Manga/{{Bokurano}} there are also pilots from ''Franchise/KingdomHearts'', ''WebComic/ElGoonishShive'', and even ''Franchise/ToyStory'' of all things! But it just doesn't end there, ''Franchise/{{Negima}}'', ''Manga/{{Chobits}}'', ''WebAnimation/BonusStage'', ''WesternAnimation/InspectorGadget'', and the CityOfAdventure most of this fanfic takes place in happens to be [[WesternAnimation/BigHero6 San Fransokyo]], complete with a freakin' [[Literature/TheDevilIsAPartTimer MgRonalds!]]
65* ''[[http://www.maison-otaku.net/~rhea/Shiva/Shiva1.html Dance of Shiva]]'', by John Biles, blends five classic {{anime}} -- along with {{Crossover Cameo}}s from and {{Shout Out}}s to at least a dozen other sources -- to create a story that is by turns action-packed, comedic, and unabashedly mystical.
66* ''[[http://slifertheskydragon.deviantart.com/art/Danny-Phantom-Rebirth-page-1-2-71036519 Danny Phantom Rebirth]]'' is yet another ''WesternAnimation/DannyPhantom'' MassiveMultiplayerCrossover webcomic.
67* ''FanFic/DarkHearts'' is ostensibly an AlternateUniverseFic that's a crossover of ''Franchise/KingdomHearts'' and ''VideoGame/FinalFantasyVII'' except for the fact that one of the main characters is also {{Dracula}} and we also have appearances from [[Anime/BlackButler Sebastian Michaelis]] and [[WesternAnimation/TheSimpsons Lionel Hutz]], with more crossovers implied in future chapters.
68* ''FanFic/DaveStdiderPokemonTraner'' takes any character from anything you've ever loved, throws their canon personalities out of the highest window of the Empire State Building, and puts them into the Pokémon world without any explanation whatsoever.
69* ''[[http://becky4paws.deviantart.com/gallery/38103386 Despite The Darkness I: A Tale After Tradgity]]'' [sic]: "A story on how the Darkness of ones imagination can be evil. It starts off as sounding like a sequel, but it is not. It is the first of it's series of books to come." Works involved in this crossover are ''VideoGame/{{EarthBound|1994}}'', Music/MichaelJackson, ''WesternAnimation/EdEddNEddy, VideoGame/Mother3, LetsPlay/TheRunawayGuys'' and ''Franchise/SuperMarioBros'' (''VideoGame/SuperPaperMario, VideoGame/SuperMarioWorld'' and ''[[VideoGame/SuperMarioGalaxy Super Luigi Galaxy]]'').
70* Creator/DetsniyOffSkiword has fanfics that end up turning into this, either through characters, or just elements of the other series. Just for starters, his ''VideoGame/KidIcarus'' fanfic ends up also being a fanfic of ''VideoGame/Left4Dead'', ''Anime/PantyAndStockingWithGarterbelt'', ''VideoGame/FinalFantasyVII'', ''Manga/DeathNote'', ''WesternAnimation/MyLittlePonyAndFriends'', ''WesternAnimation/MyLittlePonyG3'', ''Franchise/SailorMoon'', ''Franchise/KingdomHearts'' and ''Anime/CodeGeass''.
71* ''[[http://www.fanfiction.net/s/1291211 DDM: Digimon and Duel Monsters]]'' blends elements and characters from ''Franchise/{{Digimon}}'', ''Franchise/YuGiOh'', ''Manga/CardcaptorSakura'', and ''Franchise/{{Pokemon}}'' into a single setting.
72* The ''FanFic/DimensionalHeroes'' features five groups, each made up of characters both from anime and video game series and created by the five authors collaborating, placing them into the events of video games and anime.
73* One of the earliest well-known examples is 1981's "The Doctor and the Enterprise" by Jean Airey, which crosses ''Series/DoctorWho'' and ''Series/StarTrekTheOriginalSeries'' when the Fourth Doctor's TARDIS materializes in the transporter room of the USS Enterprise on her way home at the end of her Five Year Mission, and they end up traveling to a [[PaperThinDisguise barely-veiled]] {{Expy}} of Literature/{{Darkover}}.
74* ''[[http://spoon300.deviantart.com/gallery/31302955 Doctor Who: The Manga]]'' starts with the [[Series/DoctorWho Eleventh Doctor]] asking [[Manga/FullmetalAlchemist Trisha Elric]] to take in a little girl who is on the run from [[WesternAnimation/GeneratorRex Providence]] who are working on recreating The Technology of the titular characters of {{ComicBook/Livewires}} to create an Army of [[Franchise/KingdomHearts Keyblade weilders]], [[FromBadtoWorse and that's just the first three pages...]]
75* "[[http://ryuu-sei-oh.deviantart.com/art/Dragon-Ball-Xceed-Dragon-Ball-OC-Story-CH1-353621468 Dragon Ball Xceed]]" is a massive multiplayer crossover fic with the potential to be the biggest because the author intends to EVENTUALLY cross it over with everything. At least everything he can get his hands on. All in one big as hell universe. But for starters it already crossed over ''Anime/DragonBallZ'', ''Franchise/{{Batman}}'', ''Franchise/{{Superman}}'', ''ComicBook/TheMightyThor'', ''Anime/PuellaMagiMadokaMagica'', ''Anime/YuGiOhGX'', ''Anime/StrikeWitches'', and ''WesternAnimation/FamilyGuy''. Keep in mind that this fic is not written like normal fanfiction and is also about... 90% for comedy. In other words, this fic was mostly made for shits and giggles.
76* ''[[http://reseda-ptah.livejournal.com/37284.html Drawing the Line]]'' stars just about every animated character Creator/StephenColbert has ever played. Let's see--[[Series/TheColbertReport Stephen]] hires [[WesternAnimation/HarveyBirdmanAttorneyAtLaw Stephen]] to sue [[Series/TheDailyShow Jon]], who hires [[WesternAnimation/HarveyBirdmanAttorneyAtLaw Stephen]] to defend him...
77* Dreamwidth [[JournalRoleplay is host to]] an ever-increasing number of what are called multifandom roleplaying games. Some rewrite characters to fit new settings, but most are true Mega Crossovers, bringing characters together from their home canons. ''[[http://community.livejournal.com/dramadramaduck Drama Drama Duck]]'', for instance, uses the premise that people from different universes are [[HandWave somehow]] able to communicate with each other over the Internet (including people who can travel between worlds, allowing characters to meet face to face). Individual games can have very different setups, genres, possible restrictions on acceptable characters or canons, and guidelines like the involvement of {{Original Character}}s or [[OCStandIn canon OCs]].
78* ''Fanfic/DreamworldParadox'': A story where [[WesternAnimation/EdEddNEddy Ed, Double-D, Eddy, and Rolf]] as well as three {{Original Character}}s attend a massive high school and go on insane adventures. It is unknown what limit there will be to the characters but if there is a series, chances are a character from it will be appearing in some way.
79* ''Fanfic/DucktalesTwentyYearsLater'': A ContinuationFic for ''WesternAnimation/DuckTales1987'', but it also draws heavily on elements from WesternAnimation/TheDisneyAfternoon including ''WesternAnimation/TaleSpin'', ''WesternAnimation/DarkwingDuck'', ''WesternAnimation/TheThreeCaballeros'' and references to various comics, animated shorts. More importantly, it uses the timeline from ''ComicBook/TheLifeAndTimesOfScroogeMcDuck'' to pinpoint where and when this takes place as a continuation.
80* ''Fanfic/EarthsAlienHistory'' is a timeline on Website/AlternateHistoryDotCom dedicated to mixing together as many sci-fi franchises as possible into a coherent story. The count stand at one hundred and three involved at this point as of this writing.
81* ''FanFic/EddwardWrightAceAttorney'' is a crossover between ''WesternAnimation/EdEddNEddy'', ''VisualNovel/AceAttorney''... and ''VideoGame/{{Portal}}'', that last one being explained by the author's previous crossover, ''[[http://www.fanfiction.net/s/7861246 Port-Ed 2]]''. Adding to that, there's also the RecursiveFanfiction between the second and third stories with ''WebAnimation/TurnaboutStorm'', which is itself an IntercontinuityCrossover between ''Ace Attorney'' and ''WesternAnimation/MyLittlePonyFriendshipIsMagic''; thus making that four works being crossed over.
82* ''Fanfic/TheElementsOfHarmonyAndTheSaviorOfWorlds'' is a subtle example. In addition to CanonWelding the G1 ''Franchise/MyLittlePony'' show and ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship is Magic]]'', it's also established that the Earth of MLP is the same Earth as in ''WesternAnimation/{{Jem}}'', ''WesternAnimation/DungeonsAndDragons1983'', and the original ''Franchise/{{Transformers}}'' and ''WesternAnimation/GIJoeARealAmericanHero'' (WordOfGod refers to it as "Hasbro Earth"). [[spoiler: As of the latest chapters, it's more direct, as official FirstContact between Earth and Equestria has occurred.]] It's also shown in one of the side stories that the story incorporates the fan theory that Doctor Whooves is [[Series/DoctorWho the Doctor]], which brings that series in as well.
83* ''Fanfic/TheEmiyaClan'' is a [[http://forum.fanfiction.net/forum/The_Mechanics_of_In_Flight/88086/ forum]] [[http://forum.fanfiction.net/topic/88086/42932494/1/ community]]-created series of omakes/snippets based from [[http://www.fanfiction.net/u/1263379/gabriel_blessing Gabriel Blessing's]] ''Fanfic/InFlight'', featuring a theoretical GOOD END to the story that involves the next generation of children resulting from the inevitable harem. There's easily over a dozen regular "authors" and even more regular forum goers who swap ideas and characterization analysis with each other. It involves a large cast[[note]]the Clan has been crossed with (as of this writing): ''VideoGame/DevilMayCry'', ''Franchise/{{Digimon}}'', ''Franchise/{{Disgaea}}'', ''Literature/FullMetalPanic'', ''Franchise/HarryPotter'', ''Manga/{{Hellsing}}'', ''Manga/NegimaMagisterNegiMagi'', ''Franchise/LyricalNanoha'', ''Manga/OuranHighschoolHostClub'', ''Franchise/{{Persona}}'', ''Franchise/{{Pokemon}}'', ''Manga/RanmaOneHalf'', ''Manga/RosarioPlusVampire'', ''Franchise/SailorMoon'', ''Literature/HaruhiSuzumiya'', ''Literature/ACertainMagicalIndex'', ''Manga/BunnyDrop'', ''VideoGame/ValkyriaChronicles'' and a few others... not including the Franchise/{{Nasuverse}} and ''Manga/{{Sekirei}}'' elements already present in the fanfic it's based on[[/note]], most of them {{Original Character}}s on which, of course, YMMV.
84** The forum itself has actually imposed upon itself a strict code of discipline and mutual convergence to root out wanderings, FanWank, or other forms of trope misuse. Because of the nature of the community, new authors are added regularly, but work quality and content is kept in line by a democratic system for new crossovers and ideas that will be accepted as {Canon}.
85** Currently the Clan features [[VisualNovel/FateStayNight Shirou Emiya]], 24 wives, and 28 children (Further additions have been capped at this number). This is not counting various relatives, family friends, and clientele that show up in the stories on a regular basis. Usually, each child gets their own crossover(s), while the entire family (or a part of it) may participate in a story sometimes.
86** A few of the authors have compiled their works [[http://www.fanfiction.net/community/In_Flight_OMAKES/92945/99/1/1/ here]] (many more stories have been added past this point).
87* Creator/EmmaIveli is very fond of multi-crossovers. Such fics that invoke this trope are the ''Fanfic/TheNewLivesSaga'' (men from various anime being reincarnations of [[Manga/SailorMoon the Sailor Senshi]]), ''Fanfic/HarryPotterAndThe7ReincarnatedSpirits'' (seven women from various anime are reincarnated in the Potterverse), and ''Fanfic/MyHeroesReborn'' (UA students as the reincarnations of characters from various franchises). As you can see, they almost always involve {{reincarnation}}.
88* ''Fanfic/{{Empathy}}'' is a three-way crossover between ''WesternAnimation/InsideOut'', ''WesternAnimation/BigHero6'', and ''WesternAnimation/Home2015'', though in addition to those there are subtle references that suggest that other films (such as ''Franchise/DespicableMe'' and ''WesternAnimation/TheIncredibles'') exist in the same universe as well.
89* ''[[http://www.fanfiction.net/s/7919803 Eternal Flowers]]'', is a very strange example. It is loosely set in the Manga/{{Chobits}} universe, connected to Manga/XxxHolic because of {{Creator/CLAMP}}. It also involves [[Manga/NegimaMagisterNegiMagi Negima!]] and ''Anime/PuellaMagiMadokaMagica'' somehow...
90** It's actually a series. The accompanying stories are [[http://www.fanfiction.net/s/8791003 Bakamonogatari]], [[http://www.fanfiction.net/s/8574284 Puella Magi Yuuko Magica]], and the "crossroads" story that combines them all is called [[http://www.fanfiction.net/s/8796552 Parallel Souls]].
91* ''[[http://www.fanfiction.net/s/4412960 Eureka]]'', A fanfic that contains ''Ranma 1/2'' and ''Eureka'' at its core, works the idea that there's another division of "Eureka". Namely, there's the American Normal Science Branch, and the Japanese MAD Science Branch. In the end, it includes ''Ranma 1/2, Eureka, The Road To Cydonia, Dragon Ball Z, Chobits, Project A-ko, Tenchi, Neon Genesis Evangelion, Cooking Master Boy, Yu Yu Hakusho, Bleach, Kim Possible, Venture Brothers, Knight Sabers, Robotech, Naruto'' (''Naruto'' is actually only acknowledged as a manga, but still helps the cast), ''All Purpose Cultural Catgirl Nuku Nuku, Pokemon, Dexter's Lab, Jimmy Newtron, Invader Zim, X-Com, Men in Black, Pinky and the Brain, Full Metal Panic, Power Puff Girls, My Life As A Teenage Robot, Marvel Comics, Series/StargateSG1, Power Rangers, Franchise/SailorMoon, Dark Titans'' (a fanfic), ''Raiders of the Lost Ark'', and ''Gundam'' as, usually, vague little references that you will miss unless you know that series/movie/setting. However, some of them also play larger roles, or more obvious appearances.
92* ''Fanfic/EvaSessionsSomeplaceVastAndDry'':
93** Ex-Navy SEAL and CIA operative-turned-mercenary [[Film/UnderSiege William "Bill" Strannix]] [[spoiler:gets hired by Kihl to kidnap Rei and her "Mermaid" sisters from the NERV Evangelion Center, and later, make an attempt on Shinji's life at the latter's safehouse in Detroit.]]
94** [[VideoGame/DeusExHumanRevolution David Sarif]] is one of NERV's chief backers through his company Sarif Industries, [[spoiler:and later dispatches Adam Jensen to help rescue Shinji and his bodyguard Hunter from a safehouse in Detriot under siege by SEELE-backed mercenaries]]
95** [[Franchise/GhostInTheShell Daisuke Aramaki]] of the Public Security Bureau becomes the government agency version of FriendOnTheForce for Gendo, providing him with intelligence regarding SEELE activities [[spoiler:and sending Motoko Kusanagi's team to help defuse a hostage situation at the NERV Evangelion Center]]
96** [[Series/RedDwarf Arnold Rimmer]] cameos as a NERV technician [[spoiler:who assists Naoko Akagi in starting up Unit-00 for the first time with Rei as its pilot.]]
97** [[Series/{{Fringe}} Peter Bishop]] visits NERV as a representative of Massive Dynamic, [[spoiler: another potential backer that Yui and Naoko are attempting to sway to their side over SEELE.]]
98* ''Fanfic/EventHorizonStormOfMagic'' is a crossover between ''Literature/ASongOfIceAndFire'', ''Literature/TheLordOfTheRings'', ''TabletopGame/{{Warhammer}}'', and [[spoiler:later on, ''WesternAnimation/TheLegendOfKorra'']], all of which are planets in a single star system located in an original sci-fi universe set TwentyMinutesIntoTheFuture (and it's heavily implied that The Company[[TradeSnark ™]] is the megacorp from ''Film/{{Avatar}}''.)
99* ''[[http://relativeequinox.deviantart.com/gallery/#/d3gh3hh The Fandom Wars]]'' is a standard example of a Mega Crossover, though it concentrates almost entirely on the two factions of the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' world, whom are being internally manipulated into participating in the War that they didn't want to join in the first place, and the Anime Faction, one of the 'Big Three' major military powers and most likely (at least at first) to win. The series can be found in four parts. Be warned that it is very middle-tier.
100* ''Fanfic/FantasticFoxesOfZootopia'' does something similar to ''Take a Stand'', taking numerous animal-based intellectual properties and [[FusionFic mixing them into the world of]] ''WesternAnimation/{{Zootopia}}''. A major difference is that unlike ''Take a Stand'', ''Fantastic Foxes'' doesn't limit itself to Disney franchises; other than ''Zootopia'', the characters that get the most focus hail from ''WesternAnimation/FantasticMrFox'' and ''Anime/{{Aggretsuko}}''.
101* ''VisualNovel/FateStayNight'' and its various spin-offs have practically become a breeding ground for {{MassiveMultiplayerCrossover}}s, usually in the form of [[CoolVersusAwesome which non-canonical Servant]] [[UltimateShowdownOfUltimateDestiny can kick another non-canonical Servant's ass]]. ''Fanfic/FateZeroSense'', ''Fanfic/FateZeroSanity'', their sequels and countless other ones have put nearly every possible match-up imaginable together.
102* ''[[http://forums.civfanatics.com/showthread.php?t=271473 Fictionalization IV]]'', a GameMod for ''VideoGame/{{Civilization}} IV'', does this for pretty much all of fiction. Dracula's armies of toy soldiers Vs. Dr. Doom's flying saucer? ''HELL YEAH!''
103* The ''Roleplay/FictionalISOTMapGame'' series on AlternateHistory.com. Each game features many nations from different fictional sources.
104** The 1st Game had ''Anime/CodeGeass'', ''Franchise/HarryPotter'', ''Franchise/{{Transformers}}'', ''Franchise/StarWars'', ''Literature/Timeline191'', ''VideoGame/{{Fallout 1}}'', ''VideoGame/RomeTotalWar'', ''VideoGame/AgeOfEmpiresIII'', ''Literature/AColderWar'', ''Film/MontyPythonsLifeOfBrian'', ''TabletopGame/{{Warhammer}}'', ''Literature/TheDraka'', ''Literature/{{Worldwar}}'', ''Literature/WorldWarZ'', ''Film/{{District 9}}'', ''Film/{{Avatar}}'', and ''Series/GameOfThrones''.
105** Game 2 had ''WesternAnimation/{{Futurama}}'', ''Franchise/IndianaJones'', ''Literature/{{Leviathan}}'', ''Franchise/{{Halo}}'', ''Series/DoctorWho'', ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/Warhammer40000'', ''Literature/Timeline191'', ''Literature/{{Worldwar}}'', ''Literature/{{Fatherland}}'', ''Literature/TheLordOfTheRings'', ''Literature/RuledBritannia'', Boneshaker, DC and Marvel comics, ''Franchise/StarWars'', ''Literature/{{Dinotopia}}'', ''Literature/AnnoDracula'', ''WesternAnimation/RockyAndBullwinkle'', ''WesternAnimation/AvatarTheLastAirbender'', ''VideoGame/TeamFortress2'', and Joe Steele.
106** The third game had ''Literature/WorldWarZ'', ''Film/RedDawn1984'', ''Literature/RomanceOfTheThreeKingdoms'', ''TabletopGame/Warhammer40000'', ''Franchise/HarryPotter'', ''Franchise/DragonBall'', Marvel comics, ''VideoGame/{{Fallout 1}}'', ''WesternAnimation/AvatarTheLastAirbender'', ''Literature/Timeline191'', ''Series/BattlestarGalactica1978'', ''Franchise/{{Transformers}}'', ''Series/StargateSG1'' and ''Series/StargateAtlantis'', ''Literature/RavnicaCycle'', ''VideoGame/CommandAndConquerTiberianSeries'', ''WesternAnimation/SamuraiJack'', ''Literature/GulliversTravels'', ''TabletopGame/CrimsonSkies'', ''Franchise/TheElderScrolls'', ''Literature/TheLordOfTheRings'', ''Literature/{{Leviathan}}'', ''Literature/DarknessSeries'', ''Literature/TheDraka'', ''Literature/AColderWar'', ''Literature/TheHandmaidsTale'', ''Literature/TheChroniclesOfNarnia'', ''VideoGame/RuneScape'', ''Franchise/{{Pokemon}}'', ''Literature/IslandInTheSeaOfTime'', ''Franchise/MortalKombat'', ''Film/TheWizardOfOz'', ''Series/StarTrekTheNextGeneration'', ''Film/{{Godzilla1998}}'', ''Theatre/TheTempest'', ''Film/TheLostWorldJurassicPark'', and ''Literature/TwentyThousandLeaguesUnderTheSea''.
107** The fourth (and current) game has ''Series/DoctorWho'', ''Literature/TheGunsOfTheSouth'', ''WesternAnimation/TheLegendOfKorra'', ''Anime/CodeGeass'', ''WesternAnimation/TheNightmareBeforeChristmas'', ''Literature/TheDraka'', ''Franchise/StarWars'', ''Literature/{{Worldwar}}'', ''VideoGame/MassEffect2'', ''Theatre/{{Hamlet}}'', ''Literature/TheBoysFromBrazil'', ''Franchise/{{Pokemon}}'', ''Franchise/PowerRangers'', ''Webcomic/TheOrderOfTheStick'', ''Literature/Timeline191'', ''Manga/{{Naruto}}'', ''Literature/ArabianNights'', The Rising, ''Film/TheInventionOfLying'', ''VideoGame/CommandAndConquerRedAlertSeries'', ''ComicBook/New52'', ''Literature/ThePeshawarLancers'', ''Literature/{{Fatherland}}'', ''Series/BattlestarGalactica1978'', ''TabletopGame/{{Warhammer}}'', ''Website/SCPFoundation'', the ''Franchise/CthulhuMythos'', ''WesternAnimation/CaptainPlanetAndThePlaneteers'', ''Literature/{{Discworld}}'', ''Literature/{{Dinotopia}}'', ''Film/TheWizardOfOz'', ''Literature/TheHobbit'', and ''Film/DeathRace2000''.
108* The ''[[https://archiveofourown.org/series/5567 Fifteen Mokona on a Dead Man's Chest]]'' series has thus far managed to include characters from at least 22 different series created or worked on by Creator/{{CLAMP}}.
109* [[http://www.fanfiction.net/s/5389450 The Finale of the Ultimate Meta Mega Crossover]]. Featuring Literature/AFireUponTheDeep x [[Literature/HaruhiSuzumiya The Melancholy of Haruhi Suzumiya]] x Manga/AhMyGoddess x [[Literature/HaroldShea The Incomplete Enchanter]] x Literature/TheChroniclesOfAmber x Literature/CallahansCrosstimeSaloon x Series/BuffyTheVampireSlayer x Franchise/StarWars x Creator/RobertAHeinlein x FanFic/ShinjiAndWarhammer40K x FanFic/ThousandShinji x [[http://www.fanfiction.net/s/3736100/1/ Once More With Feeling]] x Manga/ReTake x Literature/{{Discworld}} x WesternAnimation/SouthPark x Film/TheMatrix. ''In the first 1400 words.''
110** Oh, and it also has Mr. Rogers from Music/UltimateShowdownOfUltimateDestiny.
111** This reaches almost Lovecraftian proportions when it goes on to include [[spoiler:all possible characters whose universes can be simulated by a Turing machine.]] Of course, most of them are off-screen.
112* ''[[https://5earths.info The Five Earths Project]]'': The five Earths are based on the main pre-Crisis Franchise/DCUniverse Earths, but some fics feature counterparts of characters from elsewhere. In [=PaladinLgt=]'s Earth-2 fics, the LA Special Crimes Unit includes [[Literature/TheDresdenFiles Karrin Murphy]], [[Literature/TheAvenger Richard Benson III]], [[Anime/{{Slayers}} Lena Inverse]], [[ComicBook/IronMan Anthony Stark]] and [[VideoGame/BaldursGate Minsc and Boo]], as well as a couple of actual DC characters (Johnny Jones Jr, the son of Genius Jones, and an Earth-2 version of [[ComicBook/JusticeLeagueOfAmerica Snapper Carr]]).
113* ''Fanfic/FracturedSovereignGFC'' pulls in three universes--''VideoGame/MassEffect''[=/=]''Franchise/StarWars''[=/=]''VideoGame/{{Borderlands}}''. Then its sequel ups the ante by pulling in ''Franchise/{{Halo}}'', from which the [[spoiler:Flood]] becomes the BigBad due to some serious [[NegativeSpaceWedgie Negative Space Wedgies]] caused by all those fancy faster-than-light drives that were helping stomp the Reapers.
114* ''Roleplay/AGameOfGods'' involves a group of mysterious beings kidnapping a host of beings from across the multiverse and throwing them into strange and perilous situations. The main cast of characters are diverse, and many of the worlds that the characters visit are drawn from other works of fiction.
115* ''[[https://archiveofourown.org/works/14487714 Game of Mass Destruction]]'' features ComicBook/TheJoker as president and ComicBook/HarleyQuinn as the First Lady and presenter of a reality TV show called Game of Mass Destruction where contestants are forced to destroy robots, have sex and kill each other for a share of $2 billion dollars. The contestants come from multiple fandoms including ''Naruto, Digimon, Pokemon, Sailor Moon, Ace Attorney, Doki Doki Literature Club, Corpse Party, Gravitation, Yu-Gi-Oh, Black Clover, Citrus, Death Note, The Cat Lady and The Letter.''
116* ''FanFic/GogglesAndTheTears'' starts where ''VideoGame/SystemShock2'' ends, with the reveal that SHODAN's far from destroyed. [[VideoGame/HalfLife Gordon Freeman]], [[VideoGame/BioshockInfinite Booker DeWitt]], and [[VideoGame/{{Marathon}} Mjolnir Recon 54]] are all drawn to the ''UNN Von Braun'' through Tears leaking into their universes, crossing paths with the Soldier, "Goggles". SHODAN now sees [[RealityWarper Elizabeth]] as her key to godhood, and will go to any lengths to get it, even if it means traveling back in time to Columbia and using a physical body.
117** [[spoiler: ''VideoGame/{{SOMA}}'' makes an appearance near the end when Goggles willingly gives himself up to SHODAN in exchange for her sparing his teammates, being sent to Pathos-II to be toyed with by a WAU-infested cyborg clone of SHODAN.]]
118** It should be noted that the caricature of Gordon Freeman used here is based on ''WebVideo/FreemansMind'', primarily because the author considered it his headcanon.
119** And a bunch of other cameos appear in the Sea of Doors, masked as parallel universes.
120* ''[[http://www.fanfiction.net/s/4869171 Grand Tour]]'' Started as a ''Manga/RanmaOneHalf'' and ''Franchise/StarTrek'' (both ''Series/StarTrekDeepSpaceNine'' and ''Series/StarTrekVoyager'') crossover, it quickly spiraled into more series, including ''Franchise/LyricalNanoha'' with many series acting as a one-chapter one-shot or a cameo mentioning at most.
121** The ''[[http://www.fanfiction.net/s/4869171/20 last]]'' chapter tops practically everything when it comes to fight scenes.
122*** And now it's ''[[http://www.fanfiction.net/s/4869171/21 complete]]''. What a ride.
123*** Update! Now with a [[http://www.fanfiction.net/s/5418545 sequel]]! Awesome.
124* ''[[https://greatmultiverse.fandom.com Great Multiverse]]'' A Fanon wiki made up of alternate universe collide with one another and an open community. Usually with multiverse wars, alternate version, powerful eldritch entities, and a lot of fandom you can think of. Most of the wars were started by the [[Characters/HalfLifeTheCombine The Combine]] invading many universes for conquest of the infinite multiverse as they can.
125* ''Fanfic/GuiltyCrownTheLostKingdoms'' is a Anime/GuiltyCrown retelling with Anime/PuellaMagiMadokaMagica as guests and takes place in an AU setting of Fanfic/YuYuGiDigiMoon. Later on, Anime/SwordArtOnline exist that the events take place after GHQ's downfall.
126* The ''Fanfic/HalloweenUnspectacular'' anthology series tends to rely on this, especially in the entries related to its {{Myth Arc}}s. It's usually just various [[Creator/{{Nickelodeon}} Nicktoons]], but later editions also bring in ''WesternAnimation/GravityFalls'', ''WesternAnimation/StevenUniverse'', and Creator/MarvelComics (both the Franchise/MarvelCinematicUniverse and the mainstream comics) as well as others.
127* ''Fanfic/TheHaterGood'' crosses over cartoons that a ton of people in RealLife hate. Their universes were banished to a void and they live together in harmony. The ones showcased so far are ''WesternAnimation/PigGoatBananaCricket'', ''WesternAnimation/PickleAndPeanut'', ''WesternAnimation/RocketMonkeys'', ''WesternAnimation/{{Breadwinners}}'', ''WesternAnimation/FanboyAndChumChum, ''WesternAnimation/SanjayAndCraig'', and ''WesternAnimation/SpaceChickensInSpace''.
128* ''Fanfic/HereBeMonsters'' combines a lot of different video-game, movie, and cartoon universes in a [[TheMultiverse Multiverse-like]] fashion with various monsters and figures from mythologies around the world.
129* ''Fanfic/HeroesSeries'' is a crossover between various properties- ''Franchise/MarvelCinematicUniverse'', ''Franchise/{{Arrowverse}}'', ''Literature/TolkiensLegendarium'', ''Franchise/{{Buffyverse}}'', ''Series/{{Smallville}}'', ''Film/XMenFilmSeries'', ''Series/Charmed1998'', ''Series/Merlin2008'', ''Franchise/TheVampireDiariesUniverse'', Franchise/DCExtendedUniverse, ''Series/{{Firefly}}'' and Series/DoctorWho to name a few.
130* ''FanFic/HorseshoesAndHandGrenades'' and its other stories, is a crossover with ''many'' previous Kamen Rider shows. The main show is ''[[Series/KamenRiderFourze Kamen Rider Fourze]]'', but it also has Kamen Riders like: [[Series/KamenRiderAmazon Amazon]], [[Series/KamenRiderV3 Riderman]], [[Series/KamenRiderDenO Den-O]], [[Series/KamenRiderDouble Double]], [[Series/KamenRiderOOO OOO]] and [[Series/KamenRiderWizard Wizard]]. It also has a cameo by [[Series/KamenRiderDragonKnight Kit and Maya]]. Many of the stories take place through SimultaneousArcs as there are different adventures that are being told throughout the story's universe.
131* ''FanFic/Hottie3TheBestFanFicInTheWorld'' and its sequel ''Hottie 4: Even Better Sequel''.
132* ''Fanfic/HybridTheory'' by Blade and Epsilon viciously satirizes the MassiveMultiplayerCrossover by presenting such a world -- but then having some of its inhabitants realize that it couldn't possibly have existed before a certain point because of the conflicting [[BackStory backstories]] of its component parts.
133** For readers who are a little slow, at one point the story focuses on, in quick succession, the [[Manga/BlueSeed Yamato-no-Orochi]], the [[VideoGame/TheKingOfFighters Yamato-no-Orochi]] and the [[Manga/RanmaOneHalf Yamato-no-Orochi]].
134* [[http://www.fanfiction.net/s/8532906 iFight Crime With Victorious]] takes ''Drake and Josh'', ''Series/ICarly'', and ''Victorious'', the latter which share their own universe, and puts them together for a superhero story.
135* ''Fanfic/InfinityCrisis'' began as a team-up between a group of superheroes from the Franchise/{{Arrowverse}} and the Avengers of the Franchise/MarvelCinematicUniverse to stop Thanos after [[spoiler:his Snap ended up affecting much of the multiverse instead of just the Avengers' Earth]]. In the first story, the Justice League of the Franchise/DCExtendedUniverse also got involved. From there, it has exploded into a group of over ''one hundred'' spin-off and side stories by various authors that have added the ''Film/XMenFilmSeries'', ''Franchise/PowerRangers'', ''Series/TheOrville'', ''WesternAnimation/HeManAndTheMastersOfTheUniverse'', ''WesternAnimation/Thundercats1985'', ''WesternAnimation/GIJoeARealAmericanHero'', ''WesternAnimation/TheTransformers'', ''Series/OnceUponATime'', ''Film/{{Descendants}}'', ''Film/{{Maleficent}}'', ''Theatre/{{Wicked}}'', ''Franchise/TeenageMutantNinjaTurtles'' and ''many'' more.
136* ''FanFic/TheInfiniteLoops'': The multiverse is on the fritz, so every world is put in a [[GroundhogDayLoop time loop]] while the admins patch things up. Occasionally a universe will reset as being merged with another universe. Or characters from one reality will be shuffled into another. Or loopers will use abilities native to a different loop that would make no sense in their current setting. Or the Admins will all dump them together in one loop [[LetsYouAndHimFight for a big brawl they can watch.]]
137* ''Fanfic/InfinityLegionHeroesUnite'' is a CrisisCrossover with a threat spanning multiple (animated) universes, so this is a given. So far, we have characters from ''WesternAnimation/DannyPhantom'', ''WesternAnimation/MyLifeAsATeenageRobot'', ''WesternAnimation/ElTigreTheAdventuresOfMannyRivera'', ''WesternAnimation/SymBionicTitan''[[note]]The story is set primarily in Sherman[[/note]], ''Franchise/Ben10'', ''WesternAnimation/GeneratorRex'', ''WesternAnimation/TheSecretSaturdays'', ''WesternAnimation/MiraculousLadybug'', ''WesternAnimation/MaxSteel'', ''WesternAnimation/RandyCunninghamNinthGradeNinja'', ''WesternAnimation/KimPossible'', ''WesternAnimation/StarVsTheForcesOfEvil'', ''WesternAnimation/SamuraiJack''[[note]][[spoiler: Featuring the surprise return of Ashi!]][[/note]], and ''WesternAnimation/PennZeroPartTimeHero'' in the mix.
138* ''Roleplay/TheInsaneQuestOfUnfathomableRandomness'', a PlayByPostGame, is an odd example. While it does take place in a universe that crosses over with ''Franchise/SuperMarioBros'', ''Franchise/TheLegendOfZelda'', ''Franchise/PiratesOfTheCaribbean'', ''Manga/{{Naruto}}'', ''Franchise/{{Pokemon}}'', ''Manga/OnePiece'', ''VideoGame/NoMoreHeroes'', and ''Manga/PandoraHearts'' (among others), none of the characters from these series are the main characters. Instead, the story focuses on a cast of original characters and settings created (mostly) from scratch by the Game Master and the participants of the game, with the characters from the above series only appearing as supporting roles, cameos, and occasionally antagonists. But other than that, the concept is pretty much the same.
139* ''Fanfic/TheInstituteSaga'' started off with Franchise/{{Superman}} and ''WesternAnimation/XMenEvolution'' before adding the rest of the Franchise/MarvelUniverse as well as [[ComicBook/{{Supergirl}} more DCU characters]], ''WesternAnimation/{{Gargoyles}}'', ''Franchise/HarryPotter'' and even some mentions to [[Fanfic/MakeAWish other]] [[https://www.fanfiction.net/s/9754636/1/The-Contract fanfics]].
140* ''Fanfic/InstrumentsOfTime'' is a massive crossover fanfiction with more than fifty characters from many different works of fiction (including ''ComicStrip/{{Dilbert}}'', ''Franchise/GIJoe'' and ''Franchise/{{Tintin}}'') and shows various teams of heroes attempting to save the universe from destruction, while various teams of villains conspire to take it for themselves.
141* In ''FanFic/TheJadedEyesSeries'' Franchise/HarryPotter has [[Manga/{{Hellsing}} Alucard]], [[Literature/TheVampireChronicles Lestat]], and [[WesternAnimation/{{Gargoyles}} the Avalon Clan of gargoyles]] among his many allies.
142* ''Fanfic/TheJeanGreySchoolNewYork'' is a fanfiction that seems to utilize Marvel's mutants as a kind of backdrop linking various fictional characters together. Notably it features [[WesternAnimation/EdEddnEddy Ed,]] [[WesternAnimation/PhineasAndFerb Phineas and Ferb,]] [[WesternAnimation/FostersHomeForImaginaryFriends Goo,]] and [[WesternAnimation/KingOfTheHill Joseph Gribble,]] as mutants attending a version of the Jean Grey Academy for Higher Learning in Manhattan.
143* ''Fanfic/JoJoNewUniverse'' is primarily an adaptation of ''Manga/JoJosBizarreAdventure'' with the human versions of characters from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' joining in. However, some parts are mainly adaptations of ''Literature/FateZero'', ''Franchise/{{Danganronpa}}'', ''Anime/NeonGenesisEvangelion'', and ''VideoGame/Persona5'', with characters from other media like ''Franchise/LupinIII'' joining in as well.
144* ''Roleplay/JourneyThroughTheMultiverse'' takes the multiverse-hopping premise from ''Series/KamenRiderDecade'' and ''Franchise/KingdomHearts'' and plays it with a huge multiversal war for power, with multiple factions taking part in the war.
145* ''Fanfic/JusticeSocietyOfJapan'': A SuperFic set in Franchise/TheDCU, staring characters from Anime/CodeGeass, Anime/TengenToppaGurrenLagann, VisualNovel/FateStayNight, ''VideoGame/XenobladeChronicles1'', ''VideoGame/FinalFantasyXIII'', Anime/PuellaMagiMadokaMagica and ''Anime/ParanoiaAgent'', with occasional references to ''Franchise/KingdomHearts'' and ''Anime/TigerAndBunny''.
146* ''Fanfic/KaijuRevolution'' features many different monsters from all manner of works from across different media, though the main focus is on the Franchise/{{Godzilla}} franchise.
147* ''FanFic/KoujaNoSenshi'': A Franchise/SailorMoon Mega Crossover series featuring Powerpuff Girls, Courage, and more.
148* ''FanFic/KingdomCrossovers'' fuses a lot of things, with [[WesternAnimation/InvaderZim Zim]] being the Franchise/{{k|ingdomHearts}}eybearer and going from everything, from ''ComicStrip/{{Garfield}}'' to ''TabletopGame/{{Warhammer 40000}}''.
149** Due to the MassiveMultiplayerCrossover nature of ''Franchise/KingdomHearts,'' many fanfics based on that canon will also use it as a catch-all explanation for blending together pretty much anything and everything. Just explain it as a new planet and there you go.
150** ''Manga/TsubasaReservoirChronicle'' is subject to this too for the same reason. There was actually a very short-lived (thank the heavens for it) fic with Tsubasa and Kingdom Hearts crossing over.
151* Many ''ComicBook/LeagueOfExtraordinaryGentlemen'' fics, since that's the original premise.
152** ''[[https://www.fanfiction.net/s/10295381/1/The-Black-Dossier-Volume-II The Black Dossier, Volume II]]'' details many non-British incarnations of the League, from a Western League comprising [[Film/TheLegendOfZorro Joaquin]] [[https://en.wikipedia.org/wiki/Ghost_of_Zorro Mason]], [[Film/TheSearchers Ethan Edwards]], [[Film/DollarsTrilogy the Man With No Name]], Series/{{Maverick}}, and [[https://en.wikipedia.org/wiki/Garter_Colt Lulu Colt]] to a sixties-Spy incarnation with [[Series/TheManFromUNCLE Nape Solo]], [[Film/OurManFlint Derryk Flint]], [[Series/GetSmart Agent 86]], [[Series/MissionImpossible James Phelps]], and [[Series/ISpy Kel Robinson]].
153** ''[[https://www.fanfiction.net/s/11463846/1/The-League-of-Extraordinary-Gentlebeasts The League of Extraordinary Gentlebeasts]]'' is set in a MouseWorld where [[WesternAnimation/AnAmericanTail Tanya Mousekowitz]], [[Literature/TheWindInTheWillows the Sea Rat]], [[Literature/TheJungleBook Rikki-Tikki-Tavvi]], [[Literature/AlicesAdventuresInWonderland the March Hare]], and the Mouse from ''Literature/TheMidnightFolk'' are recruited by a precursor to [[WesternAnimation/DangerMouse the Danger Angency]] to deal with a threat in [[Literature/DeptfordMice Deptford]].
154* ''[[http://tthf.me/Glvw The League of Extraordinary Women]]'' by Diane Castle. After the defeat of Voldemort, the Wizarding World is under attack by a new threat, and a prophecy sends Hermione Granger across universes to put together a team of heroines to combat it. She recruits [[Series/StargateSG1 Samantha Carter]], [[Series/BuffyTheVampireSlayer Buffy and Willow]], [[Series/TheBionicWoman Jaime Sommers]], [[Series/TheSecretWorldOfAlexMack Alex Mack]], and [[{{ComicBook/Catwoman}} Selina Kyle]]. There are three sequel stories:
155** ''[[http://tthf.me/1lBo Cross Purposes]]'': A collection of stories about what happens after all the heroines go back to their home universes, and look up the local counterparts to their former teammates, with mixed results.
156** ''Fanfic/TheSecretReturnOfAlexMack'': Alex returns to her universe, and applies what she's learned to becoming a real superhero and putting together her own team. This has most of the above crossovers in it, adds in several more from which Alex recruits new members for her team. (And then someone recruits ''her''.) It then adds in just about every B movie monster and bad guy, ever, for them to fight. In addition, other authors have begun contributing to this world as well.
157** ''[[http://tthf.me/jlpp Hermione Granger and the Boy Who Lived]]'' is a slightly more restrained {{Prequel}} to ''Secret Return'', which so far is, to start with, a Franchise/HarryPotter/Franchise/JamesBond crossover. Given the author, it will no doubt cross over with a lot more.
158* ''Fanfic/LifeAfterDeathTrilogy'' by [[http://www.fanfiction.net/s/6058725 SilverGryphon8]] and [[http://www.fanfiction.net/s/6058725 GamineMadcap]] ''Film/SpiderMan2''/''Theatre/AMidsummerNightsDream'' crossover starring Doctor Octopus and Robin Goodfellow. It is confirmed by the authors that the list of crossovers and cameos will include: ComicBook/{{Daredevil}} and most of the Franchise/MarvelUniverse, ''Series/{{Bones}}'', the Literature/CalLeandros books, ''Literature/TheDresdenFiles'', ''Film/TheSorcerersApprentice'', Series/DoctorWho, and more.
159* ''Fanfic/LockedInDigital'' has Izuku forced to go through nine different games (''Literature/SwordArtOnline'', ''VideoGame/{{Slender}}'', ''VideoGame/FiveNightsAtFreddys1'', ''VideoGame/{{Outlast}}'', ''VideoGame/{{Bioshock}}'', ''VideoGame/DarkSouls'', ''VideoGame/ResidentEvil'' and ''VideoGame/DeadSpace'') after he was kidnapped by a MadScientist before attending U.A.
160* ''Fanfic/LostTalesOfFantasia'' is a DarkFic that incorporates ''anything'' Creator/{{Disney}} has ''ever'' released into an epic saga set in World War II. The main protagonists are WesternAnimation/MickeyMouse, WesternAnimation/PeterPan, [[WesternAnimation/KimPossible Shego]], [[WesternAnimation/ThePrincessAndTheFrog Prince Naveen]], and a young [[WesternAnimation/PhineasAndFerb Reginald Flynn]]. The main villains are [[WesternAnimation/SleepingBeauty Maleficent]], [[WesternAnimation/TheMadDoctor Doctor XXX]], [[WesternAnimation/AliceInwonderland Al]][[AdaptationalVillainy ice]], [[WesternAnimation/TheAdventuresOfIchabodAndMrToad the Headless Horseman]], and UsefulNotes/AdolfHitler. And those are just the ''major'' characters.
161* ''Fanfic/TheLoudHouseRevamped'' is the current titleholder of the ''longest'' fanfiction in Fanfiction.net. It's a story wherein a self-insert teams up with the characters from [[WesternAnimation/TheLoudHouse the Loud House]] and partakes on many adventures into various worlds along with a ''massive'' amount of people.
162* ''Roleplay/LynchingITP'' is a cross between this, an [[Literature/InheritanceCycle Eragon]] / Literature/TheTwilightSaga HateFic, and a set of PlayByPostGames.
163[[/folder]]
164
165[[folder:M -- Z]]
166* ''Fanfic/MagicalGirlsUniteRetransformed'' sets it's sights to be the biggest MagicalGirl crossover in fanfic history, featuring franchises both well known and obscure in a celebration of the genre.
167* ''[[https://archiveofourown.org/works/35244157/chapters/87829909 Main Character Syndrome (With Exceptions)]]'' written by The_Ravenclaw_Werewolf show ''40 characters'' [[note]][[Anime/CowboyBebop Spike Spiegel]], [[WesternAnimation/AvatarTheLastAirbender Zuko]], [[WesternAnimation/TheLegendOfKorra Korra]], [[Manga/OuranHighschoolHostClub Fujioka Haruhi]], [[Manga/DeathNote L]], [[Manga/BlackButler Ciel Phantomhive]], [[Webcomic/HetaliaAxisPowers North Italy]], [[Manga/FullmetalAlchemist Edward Elric]], [[Manga/BlueExorcist Okumura Rin]], [[Manga/HunterXHunter Killua Zoldyck]], [[Manga/KurokosBasketball Kuroko Tetsuya]], [[Manga/AttackOnTitan Levi Ackerman]], [[Franchise/{{Danganronpa}} Naegi Makoto]], [[Anime/{{Free}} Nanase Haruka]], [[Anime/KillLaKill Mankanshoku Mako]], [[Manga/{{Haikyuu}} Shouyou Hinata]], [[Manga/AssassinationClassroom Shiota Nagisa]], [[Manga/FoodWars Yukihira Souma]], [[Webcomic/OnePunchMan Saitama]], [[Manga/{{Erased}} Fujinuma Satoru]], [[Manga/MyHeroAcademia Midoriya Izuku]], [[Webcomic/MobPsycho100 Kageyama "Mob" Shigeo]], [[Anime/YuriOnIce Katsuki Yuuri]], [[Manga/KissHimNotMe Serinuma Kae]], [[Manga/TheDisastrousLifeOfSaikiK Saiki Kusuo]], [[Manga/MissKobayashisDragonMaid Kobayashi]], [[Manga/TheRoyalTutor Heine Wittgenstein]], [[Manga/{{Kakegurui}} Suzui Ryōta]], [[Manga/CellsAtWork White Blood Cell U-1146]], [[Manga/ThePromisedNeverland Emma]], [[Manga/KaguyaSamaLoveIsWar Fujiwara Chika]], [[Manga/FruitsBasket Honda Tohru]], [[Manga/DemonSlayerKimetsuNoYaiba Kamado Tanjirou]], [[Manga/DrStone Ishigami Senku]], [[Manga/{{Given}} Satō Mafuyu]], [[Manga/{{Beastars}} Legoshi]], [[Manga/WelcomeToDemonSchoolIrumaKun Suzuki Iruma]], [[Manga/ToiletBoundHanakoKun Hanako]], [[Manga/JujutsuKaisen Gojō Satoru]], and [[Anime/SK8TheInfinity Hasegawa Ranga]].[[/note]] from different series being kidnapped by an unnamed god-like entity and is currently stuck in an unknown dimension. For the time being, the 40 characters spend their time trying to navigate and learn about their new surroundings, each other and their home worlds, the culture and values they go by, and [[LetsWatchOurShowPlot watching each other's journeys at the start of their own series]].
168* ''Fanfic/TheManyWorldsInterpretation'' manages to incorporate just about every significant character from ''Series/TheBigBangTheory''. As rhere aren't too many core characters here, this is understandable. However, the other half of the crossover is the ''Literature/{{Discworld}}'', ''Lots'' of Discworld characters pop in to augment the cast, both canonical and Creator/AAPessimal's OC's.
169* ''Webcomic/MariosDayJob'': A webcomic starring Mario and Luigi of Franchise/SuperMarioBros fame as (apparently) the only plumbers in Video Game Land. Linked universes include ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', Franchise/{{Pokemon}}, VideoGame/HarvestMoon (which could count for this trope on it's own) and ''VideoGame/AnimalCrossing''.
170* ''Fanfic/TheMaskedToonSinger'' pulls characters from all over the multiverse to compete on ''Series/TheMaskedSinger'', which is hosted by [[WesternAnimation/MyLittlePonyFriendshipIsMagic Pinkie Pie]] and judged by WesternAnimation/SpongeBobSquarePants, Franchise/{{Shrek}}, [[WesternAnimation/TeenTitans2003 Starfire]] and VideoGame/{{Shantae}}.
171* ''[[http://www.fanfiction.net/s/3003169 Mega Man Battle Network: A NetNavi and a Mew Mew]]'' is a {{novelization}} of the seven ''VideoGame/MegaManBattleNetwork'' games with a crossover twist.
172* ''[[https://www.fanfiction.net/s/9320201/1/Mega-Ultra-Super-Heroes-Unite Mega Ultra Super Heroes Unite]]'' by [[https://www.fanfiction.net/u/2155229/mon-ra mon-ra]] brings together heroes from ''WesternAnimation/DannyPhantom'', ''WesternAnimation/ElTigreTheAdventuresOfMannyRivera'', ''WesternAnimation/RandyCunninghamNinthGradeNinja'', ''WesternAnimation/AmericanDragonJakeLong'' and ''WesternAnimation/SheZow'' for an epic superhero crossover. Later installments would up the roster even more with shows like ''WesternAnimation/StevenUniverse'', ''WesternAnimation/{{Supernoobs}}'' and ''WesternAnimation/TheLifeAndTimesOfJuniperLee'', among others.
173* ''[[http://www.fanfiction.net/s/1230821 Mirrors Multiplied]]'' is one of the earlier and more well-known ''Manga/RanmaOneHalf'' mega crossovers on the net.
174* The ''Fanfic/MRATrilogy'', full stop. The first installment is listed as just a ''WesternAnimation/{{Frozen|2013}}'' fanfic, but includes also WesternAnimation/{{Mulan}}, [[WesternAnimation/ThePrincessAndTheFrog Tiana]], [[WesternAnimation/GravityFalls Dipper]] and many other characters, either as "[[DesignatedHero prota]][[HeManWomanHater gonists]]" or [[StrawFeminist femnazis]]. The others are remarkably more self contained: "MRA Effect", as the name implies, is mostly about ''Franchise/MassEffect'' characters with token mentions of the previous fic's exploits and a backstage war with WesternAnimation/{{Moana}}, and the final chapter is mostly about ''WesternAnimation/TheLandBeforeTime'' characters, with only the token mention of what happened before.
175* ''FanFic/TheMUSHUVerse'', a TeamUpSeries featuring various animated protagonists who band together against the forces of evil. Each subsequent story in the series adds on several shows to its continuity, though some might only get as much as a cameo:
176** ''[[https://www.fanfiction.net/s/9320201/1/Mega-Ultra-Super-Heroes-Unite Mega Ultra Super Heroes Unite]]'': Focuses on WesternAnimation/DannyPhantom, WesternAnimation/ElTigre, WesternAnimation/RandyCunninghamNinthGradeNinja, WesternAnimation/AmericanDragonJakeLong, and WesternAnimation/SheZow.
177** ''[[https://www.fanfiction.net/s/9820764/1/Ultimate-Rocking-Rivals-Unite Ultimate Rocking Rivals Unite]]'': [[LongList Adds on]] WesternAnimation/AtomicBetty, WesternAnimation/KimPossible, WesternAnimation/BuzzLightyearOfStarCommand, WesternAnimation/StarWarsTheCloneWars ([[FridgeLogic somehow]]), WesternAnimation/MyLifeAsATeenageRobot, WesternAnimation/WordGirl, WesternAnimation/KidVSKat, WesternAnimation/MaxSteel2013, WesternAnimation/PhineasAndFerb, WesternAnimation/DextersLaboratory, WesternAnimation/ThePowerpuffGirls, Series/TheAquabatsSuperShow, Franchise/TheIncredibles, WesternAnimation/TheFairlyOddParents, and WesternAnimation/TheAwesomes.
178** ''[[https://www.fanfiction.net/s/10299331/1/Vacationing-Hero-Families-Unite Vacationing Hero Families Unite]]'': Throws ''WesternAnimation/LiloAndStitchTheSeries'', ''{{WesternAnimation/Freakazoid}}'', and ''WesternAnimation/MakingFiends'' into the mix.
179** ''[[https://www.fanfiction.net/s/10527559/1/Super-Eggheaded-Geniuses-Unite Super Eggheaded Geniuses Unite]]'': Brings in WesternAnimation/InvaderZim, WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius, WesternAnimation/JohnnyTest, WesternAnimation/BigGuyAndRustyTheBoyRobot, WesternAnimation/TotalDrama, WesternAnimation/TheLifeAndTimesOfJuniperLee, WesternAnimation/TronUprising, WesternAnimation/TeenageMutantNinjaTurtles2003, and {{WesternAnimation/Robotboy}}.
180** ''[[https://www.fanfiction.net/s/10926190/1/Secret-Files-of-OWCA Secret Files of OWCA]]'': Centers in on WesternAnimation/ScoobyDooMysteryIncorporated, WesternAnimation/ChipNDaleRescueRangers, WesternAnimation/ThePenguinsOfMadagascar, WesternAnimation/InspectorGadget, {{Franchise/Tintin}}, Anime/SpeedRacer, WesternAnimation/CodenameKidsNextDoor, WesternAnimation/MuchaLucha, and WesternAnimation/CourageTheCowardlyDog.
181** ''[[https://www.fanfiction.net/s/11597897/1/Amazing-Mystical-Warriors-Unite Amazing Mystical Warriors Unite]]'': Includes ComicBook/MonsterAllergy, WesternAnimation/StevenUniverse, WesternAnimation/JackieChanAdventures, and {{WesternAnimation/WITCH}}.
182** ''[[https://www.fanfiction.net/s/11773174/1/Agents-of-WADDLES Agents of WADDLES]]'': Adds WesternAnimation/ParaNorman, {{WesternAnimation/Coraline}}, WesternAnimation/TheWildThornberrys, WesternAnimation/GrowingUpCreepie, {{WesternAnimation/Fillmore}}, WesternAnimation/SallyBollywood, WesternAnimation/TheReplacements, Literature/EdgarAndEllen, WesternAnimation/StarVsTheForcesOfEvil, WesternAnimation/KickButtowskiSuburbanDaredevil, [=The DaVincibles=], Get Ace, {{WesternAnimation/Detentionaire}}, and WesternAnimation/XiaolinShowdown.
183* ''Fanfic/MyHeroPlaythrough'' is set in a variant of the Manga/MyHeroAcademia universe, where Izuku has the power of Webcomic/TheGamer. Hints in story and WordOfGod imply there is more of Webcomic/TheGamer to the story than just Izuku's powers (if [[Characters/TheGamer Shin Sun-Il]] being name dropped as a Korean Hero can be called a hint). In addition, four members of class 1-A and one member of class 1-B are replaced by characters from five other series, namely [[Franchise/SailorMoon Mizuno Ami]], [[Manga/ACertainScientificRailgun Misaka Mikoto]], [[ComicBook/Batgirl2000 Cassandra Cain]], [[Literature/FateApocrypha Mordred Pendragon (here having her name adapted as Penryu Modura)]], and [[Manga/{{Gamma}} Shimooka Hikari]]. Also, Tokiwadai from the Railgun series is referenced as a special Heroine training middle school.
184* ''Fanfic/MyLifeAsATeenagedVonNeumannDevice'' primarily focuses on ''WesternAnimation/MyLifeAsATeenageRobot'', but is absolutely ''loaded'' with subtle and not-so-subtle references to other Nickelodeon and Cartoon Network cartoons. Among other things, the Cluster has been having trouble with [[WesternAnimation/InvaderZim the Irkens]] and [[WesternAnimation/TheFairlyOddParents the Yugopotamians]], and Dr. Wakeman's old college roommate was [[WesternAnimation/EvilConCarne Dr. Ghastly]].
185* ''FanFic/NackAndPsycho'': A Mega Crossover that is also a [[Franchise/SonicTheHedgehog Sonic]] ContinuityReboot starring [[VideoGame/SonicTripleTrouble Nack the Weasel]] and [[Film/WhoFramedRogerRabbit Psycho]] as the main characters.
186* "The Never-Ending Battle" by Rob Morris. Take ''[[Series/{{Mash}} M*A*S*H]]'' as the core fandom. Add in that several of the characters just happen to be ''Franchise/{{Highlander}}''-style Immortals and that before becoming Mulder's nemesis the Cancer Man was running experiments in Korea in the early 50's. Oh, and Sherman Potter is descended from a ''[[Series/BuffyTheVampireSlayer BtVS]]''-style Slayer and came home from WWI with one [[Series/ForeverKnight Nick Knight]] in tow. Then there's Hawkeye and Hot Lips' roles in the Eugenic Wars from ''Franchise/StarTrek'', not to mention the way that most of the human crew-members of ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' can trace their family bloodlines back to someone who served at the 4077th. And let's not forget about BJ's wife Peggy... and her half-sister [[Series/{{Bewitched}} Samantha Stevens]]. By the time Franchise/{{Godzilla}} shows up you don't even bat an eye. Of course Godzilla and ''M*A*S*H'' can co-exist in the same universe -- giant lizard monsters aren't really that strange.
187* [[http://neverendingstrugglerpg.freeforums.org/ Neverending Struggle: Multiverse at War]] is a forum RPG based entirely on this trope. Basically, in a world where all fictional characters live, a war breaks out. Each separate faction (Individual Armies) is trying to take over the world. It has an incredible amount of 3 players, probably because of lack of advertisement.
188** Also, from the same person who manages that, comes ''[[http://www.fanfiction.net/s/4457855 Ookami no Monogatari]]'' and ''[[http://www.drunkduck.com/Wolfeye_City/index.php?p=631162 Wolfeye City]]''. Ookami no Monogatari is about a group of characters from different dimensions (fictional works)--at the moment, ''Manga/OnePiece'' and ''VideoGame/MegaManX''--being lead by a teenage girl to various missions. Wolfeye City also uses the AuthorAvatar trope, since it's about Alter-Egos, the comic representations of the author and some of her friends, fighting demons who are trying to destroy the city, who is filled with anime and video game characters. All three are Better than it Sounds. Though, Erase Alpha, the author, must love this trope.
189** All three are {{dead|Fic}}. And now [[http://neverendingstruggle.free-forums.cc Neverending Struggle V2]] and [[http://imagine.forummotions.com/ IMAGINE]], both MassiveMultiplayerCrossover [=RPGs=] (not very active at the moment though).
190* ''[[http://www.fanfiction.net/s/3695276 Never Too Young]]'' by Koolkame. ''WesternAnimation/{{Ben 10}}, WesternAnimation/{{WITCH}}, WesternAnimation/DannyPhantom, WesternAnimation/TheLifeAndTimesOfJuniperLee, WesternAnimation/AmericanDragonJakeLong,'' with cameos from ''Manga/NegimaMagisterNegiMagi, WesternAnimation/BackToTheFuture: TheAnimatedSeries, WesternAnimation/XMenEvolution, WesternAnimation/JusticeLeagueUnlimited, ComicBook/FantasticFour'' and ''WesternAnimation/JonnyQuest''.
191* ''Fanfic/NewGameNewLife'', written by ''[[https://www.fanfiction.net/u/10922478/Adudefromthesea Adudefromthesea]]'' is a [[SelfInsertFic self insert]] MassiveMultiplayerCrossover FusionFic. Set in the 90s at the start of ''Manga/RanmaOneHalf'', a young man finds himself in the body of a teenager named Ōe Hiroshi and [[{{SuddenGameInterface}} seeing floating boxes reporting his status]]. Pretty much every manga, anime, and/or video game made or set during TheNineties is present in this setting. Plus a few more that can be reasonably adapted.
192* The ''Nicholas Andersen Trilogy'' takes elements from ''Inside Out'', ''4th Moon Of Xyth'', ''The House Of The Dead'', ''Star Wars'', ''SCP Foundation'', ''Percy Jackson And The Olympians'', ''El Eternauta'', and ''Miraculous Ladybug''. Altough the focus is primarily on ''Inside Out'' for the first part and ''Miraculous Ladybug'' for the third, the rest of the works provide either tools for the characters, or antagonists to defeat.
193* ''Webcomic/NicktoonsTales'' is a fancomic that sews all Nicktoons settings into one planet, as well as original characters living on that planet.
194* [[http://nickfanon.wikia.com/wiki/The_Nintendo_Show! The Nintendo Show]] has, to name a few, Mortal Kombat, Angry Birds, Pokemon, Bomberman, Metal Gear Solid, and many, many others fighting the villians.
195** Also, in the same series, there is a planet with all ''anime'' settings sown into it.
196* ''[[http://addventure.bast-enterprises.de/28839.html Nuclear Fusion]]'' on the [[http://addventure.bast-enterprises.de/ Anime Adventure]]. Noteworthy because it manages to mix up elements of over one hundred completely unrelated series and manages to combine them into a single massive Fallout inspired Post-Nuclear world, and not only make sense, but tell an interesting and unique story.
197* ''[[http://s1.zetaboards.com/Obscurite_Musicale/index/ Obscurité Musicale]]'' is an active RPG that crosses over, mostly,''Theatre/ThePhantomOfTheOpera'', ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'', and ''Theatre/LesMiserables''-- as well as ''Theatre/JekyllAndHyde'', ''Billy Budd'', and ''Theatre/SpringAwakening''. As well as one or two actual historical figures, and a less-vampiric [[Theatre/TanzDerVampire Herbert von Krolock]]. You guessed it-- it's very, very AU, but serious in tone. The in-character chatbox can't have the same said for it, being the ungodly place that spawned the pairing of [[Literature/TheTwilightSaga Edward]] and [[ComicBook/TheSandman the Corinthian]]. They're both on crack, of course. Just different kinds of crack. It's... weird. Some parts hang together fairly well. Some are a bit weird.
198* A recent remake of Disney's ''WesternAnimation/OnceUponAStudio'' aptly named ''Fanfic/OnceUponAStudioVersionTwoPointOh'' takes this even further than the existing short, and shows WesternAnimation/{{Moana}}'s father returning (voiced once again by Creator/TemueraMorrison), cameos by the Spring Sprite and Yo-Yo Flamingo from WesternAnimation/Fantasia2000, and even [[WesternAnimation/TheLionKing1994 Mufasa]] [[GhostReunionEnding in ghost form]].
199* ''[[http://www.fanfiction.net/s/4131406 Overkill]]'' starts out as a ''Manga/{{Naruto}}''/''[[Franchise/LyricalNanoha Nanoha]]'' crossover, and then becomes the author asking, [[AuthorAppeal "How many fictional characters can I conceivably put in this?"]]
200* ''FanFic/OzyAndMillieAdventures'' is this. Webcomic/OzyAndMillie have, so far, encountered Literature/TheCatInTheHat and the Literature/MrMen in this fanfic.
201* ''FanFic/PaperMarioX'' is a series of {{novelization}}s of the ''VideoGame/PaperMario'' games... with characters from ''Franchise/TheLegendOfZelda'', ''Franchise/SonicTheHedgehog'', ''Franchise/{{Kirby}}'' and ''Franchise/{{Metroid}}'' added to the story.
202* ''[[http://www.fanfiction.net/s/8708822/1/ The Perfect Hero]]'' is a story in which a GaryStu goes through inumerous series, continuities and even RealLife creating instantly [[HappyEnding happy endings]] for everyone. [[spoiler: In the end, it's a deconstruction of the GaryStu trope because even if he has the power to create happy endings, he has no power to create a happy ending for himself]].
203* ''Personality Conflicts'' by Ellen Brand melds ''Franchise/PowerRangers'' with a spade of unrelated properties, including ''WesternAnimation/DannyPhantom'' and ''Manga/CaseClosed'', but her masterpiece is probably the ''[[http://www.fanfiction.net/s/264803 Trial Arc]]'', where the Rangers are forced to defend Zordon in galactic court for his actions over the course of the series, while a resurrected villain forces the ''Series/VRTroopers'', ''Series/{{Beetleborgs}}'', ''Series/MaskedRider'', and previous crossover allies ''[[WesternAnimation/TheRealGhostbusters the Ghostbusters]]'' to defend Earth. Also notable as the storyline provides a [[GrandFinale "proper" finale]] for each of PR's sister shows.
204* ''Fanfic/{{PRIMARCHS}}'' not only pulls this off, but ''justifies it'' from the 2nd arc onwards by the inclusion of an entity called the Plot Hole.
205* ''[[http://www.florestica.com/brandall/poe/index.htm Process of Elimination]]'' starts off primarily as a ''Manga/RanmaOneHalf'' and ''Anime/TenchiMuyo'' story, but has many additional anime added to its story.
206* ''[[http://www.fanfiction.net/s/3415504 Prodigy]]'' is a crossover between: ''Literature/HarryPotter'', ''{{Series/CSI}}'', ''Series/{{House}}'', ''Series/GreysAnatomy'', ''{{Series/Numb3rs}}'', ''Psych'', ''Series/LawAndOrderSpecialVictimsUnit'', ''Series/NCIS'', and possibly even more.
207* ''[[http://www.tthfanfic.org/Story-8583/Greywizard+Prophecies+We+Don+t+Need+No+Stinking+Prophecies.htm Prophecies? We Don' Need No Stinkin' Prophecies]]'' by Greywizard (also on Twisting The Hellmouth) shows a Franchise/{{Buffyverse}} where Harry Potter was raised by a married Xander and Buffy, and the forces of the Watcher's Council include characters from, according to the author: ''Tears of the Sun; Blackhawk Down; White Sands; Series/{{ER}}; ComicBook/{{Witchblade}}; Series/{{Supernatural}}; ComicBook/{{Raven}}; Series/PSIFactor; Film/CityOfAngels; Film/UnderSiege; Series/ChicagoHope; Series/StargateSG1; Series/TheXFiles; Series/NYPDBlue; The Craft; ComicBook/RogueWarrior''; the Creator/TomClancy novels; ''Franchise/XMen; Rainbow Six; Franchise/LawAndOrder''; the ''Film/LethalWeapon'' movies; the ''Amber'' books; ''Film/AlienVsPredator; Film/PracticalMagic; [[Literature/TheExecutioner Phoenix Force]]''; and ''Series/SabrinaTheTeenageWitch'' (plus another ''Buffy'' fanfic, plus ''Buffy'' and ''Literature/HarryPotter'' themselves, for a total of 29 sources).
208* ''Fanfic/TheQuestForTheHoleyGrail'' is a RougeAnglesOfSatin tale of Myth/KingArthur and Lancelot's quest for the titular grail, which is joined by Literature/HarryPotter, Hagrid, "[[Franchise/IndianaJones indian Jones]]", "[[Literature/TheLordOfTheRings the lord of the rings people]]", Series/DoctorWho, "professor snake" (a character who can only be Professor Snape), and inexplicably, WesternAnimation/ScoobyDoo and the Mystery Machine. They eventually have a massive epic battle with the "drak ones", who include the "lick king from [[VideoGame/WorldOfWarcraft Wrodl fo Warcraf]]", "Voldermor", Sauron, and the "russian woman from [[Film/IndianaJonesAndTheKingdomOfTheCrystalSkull indian Jones and the crystal skull]]".
209* ''Fanfic/TheReactsverse'' crosses over ''WebAnimation/{{RWBY}}'' with ''VideoGame/FireEmblemAwakening'' and ''Anime/PuellaMagiMadokaMagica'', in addition to other series lacking a Reactsverse fic, like ''Franchise/{{Persona}}'' and ''Literature/{{Toradora}}'' as well as the ''Franchise/{{Nasuverse}}''.
210* WebVideo/TheReviewTeam is shaping up to be this quite a lot. The title itself is a self-admitted [[ArtifactTitle artifact title,]] as it now focuses on the adventure of a team of 10 heroes and villains from across the multiverse (mostly cartoons) to help an eccentric knight hold off a number of baddies, such as a mysterious Great Evil, [[VideoGame/PrimalRage Necrosan,]] evil generals, monsters of all shapes and sizes, and...well, let's just say it doesn't take itself seriously at the right times. Currently, the series is still in development and the Tropes page is going through a major change while the artist redraws everything from Seasons 1-3.
211** Thus far, the main franchises are ''Franchise/{{Godzilla}}'', ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', ''WesternAnimation/AdventureTime'', ''Franchise/{{Transformers}}'', ''Film/BatmanAndRobin'', ''WesternAnimation/TheAmazingWorldOfGumball'', and so on! And that's not even counting the {{Original Character}}s, whom thankfully know their place, yet still have prominent roles.
212* ''Webcomic/{{Roommates}}'' and its ''{{Webcomic/Buildingverse}}'' Spin-Offs. ''Webcomic/GirlsNextDoor'', ''Webcomic/DownTheStreet'', ''Webcomic/{{Superintendent}}'' and ''Webcomic/MeanwhileUpstairs'' are all FanWebcomics on Website/DeviantArt, that bring various fictional characters together in an out of canon world. The main characters are from ''Film/{{Labyrinth}}'', ''Theatre/LesMiserables'', ''Literature/ThePhantomOfTheOpera'' and ''Franchise/PiratesOfTheCaribbean'' (DTS adds ''Literature/{{Dracula}}'' and ''Literature/{{Frankenstein}}'', MU ''{{Literature/Nightside}}'' and ''Series/CriminalMinds'') with countless [[TheCameo cameos]] ShoutOut s etc..
213* ''Fanfic/ScrambleverseAFicForAllAndNone''
214* ''Fanfic/TheSecretLifeOfDolls'', A Dollfic by Creator/CleolindaJones, writer of ''Movies in Fifteen Minutes''.
215* ''Fanfic/ShatteredSkiesTheMorningLights'', which brings together all five of the most famous MagicalGirl series: ''Franchise/SailorMoon'', ''Manga/CardcaptorSakura'', ''Anime/PrettyCure'', ''Franchise/LyricalNanoha'', and ''Anime/PuellaMagiMadokaMagica''.
216* ''Fanfic/ShinnenNewYear'' is a massive story of being set after Anime/GuiltyCrown. It is also the series finale of Fanfic/KaniusProductionAbridged.
217* Fanfic/SleepingWithTheGirls, by Admiral Tigerclaw, is essentially a {{Deconstruction}} of the SelfInsertFic, in which a normal guy (albeit one who's been through boot camp) is thrust into various fictional worlds by an unusual mechanism: He 'jumps' to each world the moment he falls asleep, and he wakes up in the same bed as a female character. Naturally, HilarityEnsues. Note that the action scenes are military-focused (with good reason) and many times more epic than you may remember them being in that particular episode.
218* ''Website/SNAFUComics'' have several webcomics that are crossovers. The most crossover-ish of them are ''Webcomic/PowerpuffGirlsDoujinshi'' and ''Webcomic/GrimTalesFromDownBelow'', which feature crossovers of almost every Creator/CartoonNetwork and Creator/{{Nickelodeon}} cartoon (mostly, indeed, from CN).
219* ''Fanfic/SognicMalltiverseOfMadness'': The series features a variety of characters from various parts of the ''Franchise/SonicTheHedgehog'' franchise, including both games and cartoons. It also features other FunnyAnimal video game characters, including [[VideoGame/FiveNightsAtFreddys Freddy, Bonnie, and Chica]], VideoGame/AeroTheAcroBat (referred to as Airo Arco-Bat), and VideoGame/{{Bubsy}} (referred to as Bubzy Bobket.) Bubzy also states that other "90's video game mascots" are canon to this world, though which ones exactly haven't been revealed yet. There are also some {{Original Character}}s.
220* ''Fanfic/SongsOfTheSpheres'' features characters from more than 20 franchises regularly and more than two scores more less regularly.
221* ''[[http://www.fanfiction.net/s/3613566 Sonic the Hedgehog: Rise of Nazo]]'' is a Mega Crossover that is based on ''Nazo Unleashed''. Two more Mega Crossovers followed after it.
222** Another Sonic Mega Crossover ''[[http://www.fanfiction.net/s/3027838 Catch Me if you Can]]'' has Dr. Eggman skillfuling dupeing a pack of ''{{Magical Girl}}s'' to attack Sonic. This is one of his most clever plots as Sonic is shown to have gynophobia.
223** And then there's another Mega Crossover called ''[[http://www.fanfiction.net/s/3989072 Multi-Dimensional Melee!]]'' which manages to include some pretty unlikely characters, and yet primarily focus on Sonic. The story follows an [[WesternAnimation/SpiderManTheAnimatedSeries accidentally familiar plot]] which includes a CrackPairing, several {{Original Character}}s, [[BreakingTheFourthWall fourth wall breaking]], a [[HeWhoMustNotBeSeen faceless]] [[BigBad plot orchestrator]], and a seemingly decent amount of followers. Several {{continuity nod}}s and series trademarks are also thrown here and there.
224* The infamous ''[[https://www.fanfiction.net/s/9532463/1/Sonic-s-Ultimate-Harem Sonic's Ultimate Harem]]''. A story in which Sonic (who isn't actually Sonic but rather a self-insert) tells Mario about his endeavors involving sleeping with over '''360''' women from 107 different franchises. These include: ''1080 Snowboarding, ARMS, Ace Attorney, Akame Ga Kill!, American Dad, Anarchy Reigns, Ao No Exorcist, Battle Chasers, Battleborn, Bayonetta, Ben 10, Big Hero 6, Bioshock, Black Lagoon, [=BlazBlue=], Bleach, Bloodrayne, Borderlands, Call of Duty, Code Geass, Crash Bandicoot, DC Comics, Danger Girl, Danny Phantom, Darksiders, Darkstalkers, Dead or Alive, Devil May Cry, Digimon, Donkey Kong Country, Dragon Ball, Dragonaut the Resonance, Fairy Tail, Final Fantasy, Fire Emblem, Freedom Planet, G.I. Joe, Ghost in the Shell, Guilty Gear, High School DXD, Highschool of the Dead, Jak and Dexter, Kid Icarus, Kill la Kill, Killer Instinct, Kim Possible, King Of Fighters, Kingdom Hearts, League of Legends, Legend of Zelda, Lollipop Chainsaw, Loonatics Unleashed, Looney Tunes, Lupin the Third, Majikoi, Marvel Comics, Mass Effect, Metroid, Mobile Suit Gundam, Mortal Kombat, My Hero Academia, My Little Pony, Naruto, Ninja Gaiden, One Piece, Overwatch, Paladins, Panty and Stocking with Garterbelt,Pokemon, Queen's Blade, RWBY, Ratchet and Clank, Rayman, Resident Evil, Rumble Roses, Sailor Moon, Shantae, Skullgirls, Sly Cooper, Soul Calibur, Soul Eater, Space Channel 5, Star Fox, Star Wars: The Clone Wars, Street Fighter, Super Mario, Swat Kats, TUFF Puppy, Teen Titans, Teenage Mutant Ninja Turtles, Tekken, Tengan Toppen Gurren Lagann, The Fairly Oddparents, The Incredibles, The Secret Saturdays, Thundercats, Tomb Raider, Total Drama, Virtua Fighter, Vocaloid, Who Framed Roger Rabbit, Witchblade, Wonder over Yonder, Wreck-it-Ralph, Xiaolin Showdown, Young Justice and Yu-Gi-Oh!''.
225* ''[[http://suburbansenshi.com Suburban Senshi]]'', which brings in all sorts of series into the ''Franchise/SailorMoon'' universe.
226** Justified (well, as justified as such a thing can be in the fanfic industry) in the ''Sailor Moon Expanded'' universe; a method of trans-dimensional travel allows characters from the Sailor Moon universe to travel to other dimensions on the conceit that ''every anime and manga ever produced'' has its own separate universe. The various Dark Kingdom Renegades seemed to run into this quite often in their early years on Earth, having traveled to the worlds for ''Anime/BubblegumCrisis'' and ''Manga/RanmaOneHalf'' just for starters, and later to ''Anime/{{Urotsukidouji}}'' (aka ''Legend of the Overfiend''), where Titanite (youma Sailor wannabe, for those just joining us) encountered said Overfiend. With her disguise device set to Sailor uniform... [[{{Squick}} and broken]]. Thankfully, the author managed to avoid following the obvious to its conclusion in a manner most awesome. And in an [[DeadFic unfinished story]], Titanite finds herself in ''Anime/NeonGenesisEvangelion'', and unfamiliar with the series, tries to understand it in terms of the classic HumongousMecha shows she's seen in the past.
227** To make things doubly interesting, the laws of these various dimensions seem to apply themselves to trans-dimensional visitors over time. Thus, in the Ranmaverse, [[AloofBigBrother Calcite]] takes on the mannerisms of a wizened martial arts master, and felinoid Margrave becomes even more {{catgirl}}ish than usual. The DKR use this to their advantage; as long as they remain in the ''Sailor Moon'' universe and work on behalf of the forces of good, they are nigh indestructible.
228* ''FanFic/Spongebob2019'' brings almost all of the Nickelodeon characters together to defeat a now out-of-character and power hungry ''WesternAnimation/SpongebobSquarepants'', with appearances from other shows that aren't originally from the main Nick lineup like ''WesternAnimation/BeavisAndButthead'' (MTV), ''WesternAnimation/BluesClues'' (Nick Jr.), ''Series/{{Degrassi|TheNextGeneration}}'', ''Series/H2OJustAddWater'' (Creator/TeenNick) and ''Series/PowerRangersSamurai'' (This airs on Nick in the US, but not really a Nick original).
229* ''FanFic/TheStoryToEndAllStories'' is one gigantic crossover. It includes characters from ''Series/DoctorWho'', ''Literature/TheHungerGames'', ''Franchise/StarWars'', ''Franchise/IndianaJones'', ''Film/ThePrincessBride'' and ''Series/MysteryScienceTheater3000'', among many others. It also features an appearance by the king of crossovers, JustForFun/JohnMunch.
230* ''Fanfic/TheStringsWePull'' sees ''VideoGame/{{OneShot}}'', ''VideoGame/{{Deltarune}}'', ''VideoGame/{{OFF}}'', ''VisualNovel/PurrfectApawcalypse'', ''VideoGame/NightInTheWoods'', ''VideoGame/TheHex'', ''VideoGame/{{Inscryption}}'' and ''Podcast/TheMagnusArchives'' crossing over.
231* ''Fanfic/SunsetsIsekai'': Where do we even start? Nearly every chapter crosses over with some work or other- fanfics (some of which are themselves crossovers), TV shows, video games, manga… Many chapters even cross over with more than one work at a time.
232* ''FanFic/SuperMagicaWars'' (found [[http://www.fanfiction.net/s/9026860 here]]) is a MagicalGirl and-then-some themed ''VideoGame/SuperRobotWars'' type fic, with its primary roots in ''Anime/MagicalGirlLyricalNanohaAs'', but including a batch of series that fit the theme without explicitly being MagicalGirl series, like ''Manga/BusoRenkin'' and ''Series/{{Garo}}''. Taking on the [=SRW=] theme, it also includes one or more original characters, and as a surprise guest, it includes ''Anime/PuellaMagiMadokaMagica''... but as ''FanFic/MagicaMadokaVeneficusPuella'' rather than the canon version.
233* [[http://alaxr274.deviantart.com/gallery/33810717 Super Milestone Wars]]
234** [[http://alaxr274.deviantart.com/gallery/36864527 Super Milestone Wars 2]]
235*** [[http://alaxr274.deviantart.com/gallery/36864534 Kamen Rider x Super Sentai x Super Milestone Wars: Crossover Taisen]] is a crossover of Super Milestone Wars 2, Franchise/KamenRider and Franchise/SuperSentai.
236* ''Fanfic/SuperRWBYSisters'' takes the world of WebAnimation/{{RWBY}} and throws it into the world of Creator/{{Nintendo}}. In addition, there are several "guest" universes such as ''Franchise/SonicTheHedgehog'', ''Franchise/{{Danganronpa}}'', ''VideoGame/ShovelKnight'', ''VideoGame/{{Shantae}}'', ''VideoGame/DevilMayCry'', ''Anime/AkameGaKill'', ''VideoGame/{{DOOM}}'', ''VideoGame/Persona5'' and much more.
237* ''Fanfic/SuperSentaiVsPowerRangersTheLiveblog'' serves as one to several ''Power Rangers'' and ''Super Sentai'' series similar to the work covered, ''Fanfic/SuperSentaiVsPowerRangers''. It also adds several Sentai and Ranger actors into the mix.
238* ''Fanfic/SuperSmashBrosTheAnimatedSeries'': It was inevitable, given [[VideoGame/SuperSmashBros the games it's based on]], but the series also throws in characters from ''WesternAnimation/BatmanTheAnimatedSeries'', ''Anime/AttackOnTitan'', ''WesternAnimation/{{Coco}}'', ''Anime/DragonBallZ''...and ''Animation/SuperWings'', weirdly enough.
239* In ''[[http://www.thekeep.org/~rpm/sw/ The (sur)Real World]]'' a Japanese TV network does its own version of ''Series/TheRealWorld'', and thus sticks together in one house Nuku-Nuku (''Anime/AllPurposeCulturalCatgirlNukuNuku''), Washu (''Anime/TenchiMuyo''), Urd (''Manga/AhMyGoddess''), Mamoru Chiba (''Anime/SailorMoon''), Kyosuke Kasuga (''Manga/KimagureOrangeRoad''), Ataru Moroboshi (''Manga/UruseiYatsura''), and Ranma Saotome (''Manga/RanmaOneHalf'').
240* ''FanFic/{{Survivability}}'' tells its own plot in the Manga/{{Bleach}} universe through KPop characters (from at least 4 different fandoms).
241* [[http://www.fanfiction.net/s/6895088 Sweet Dreams]] has ''Film/{{Labyrinth}}, Franchise/ANightmareOnElmStreet, Film/{{Inception}}'' and ''ComicBook/TheSandman1989''.
242* ''Webcomic/TailsGetsTrolled'' starts off with ''Franchise/SonicTheHedgehog'' and ''Franchise/SuperMarioBros'', two [[DuelingWorks semi-related]] franchises, but then goes batshit by having characters from both series team up (or become enemies) with characters from ''WesternAnimation/LooneyTunes'', ''ComicBook/TheIncredibleHulk'', and ''VideoGame/LeagueOfLegends''. And even more characters from other franchises are almost constantly introduced, to the point where it's hard to name all of them.
243* ''Fanfic/TakamachiNanohaOf2814'' fuses together ''Franchise/LyricalNanoha'', the DCAU, ''Manga/FateKaleidLinerPrismaIllya'', ''Manga/NegimaMagisterNegiMagi'', ''Anime/SailorMoon'', and ''Manga/CardcaptorSakura'' in a [[RuleOfCool hilariously awesome story]]. It begins with, shortly before becoming a MagicalGirl... Nanoha ends up becoming a Franchise/GreenLantern. And then the rest of the franchises get added in until it can become easy to lose track of who's doing what (especially since the Negima and Cardcaptor Sakura characters are convinced that to be proper magical girls they're required to use {{Code Name}}s). The story has just finished going through the first two seasons of Nanoha (the second of which ends up being combined with [[VisualNovel/FateStayNight the Holy Grail War]]), and has begun on the first season of WesternAnimation/JusticeLeague with more and more craziness added in thanks to the crossovers.
244** Anything by [[http://www.fanfiction.net/u/849822/ Shadow Crystal Mage]] will invariably become this once it has enough chapters. Special mention also goes to [[http://www.fanfiction.net/s/2677761 Raikiri Triken]].
245* ''Fanfic/TakeAStand'' inserts characters from virtually every animal-based Disney franchise into ''WesternAnimation/{{Zootopia}}''. Of particular note, Robin Hood and Maid Marian are Nick's parents. The third installment takes it a step further by opening a portal to the Marvel Comics Universe.
246* ''[[http://www.tthfanfic.org/story.php?no=11757 Tales From The Barman...]]'' and ''[[http://www.tthfanfic.org/story.php?no=19941 Tales From The Barman... Part II]]'' implement a MassiveMultiplayerCrossover through the device of a bar run by Xander of ''Series/BuffyTheVampireSlayer'', in Cleveland after the end of the series. Each chapter is its own small crossover fic, ranging from vignettes to full stories, with characters from dozens of settings ranging from Michael Moorcock's Eternal Champion to ''Series/{{Cheers}}'' making an appearance and telling their tales.
247* ''Tales Of Toons: Fanfic/KnightOfLolicon'', which was shilled on this wiki, and is a crossover of ''Anime/DragonBallGT'', ''Franchise/{{Transformers}}'', ''Manga/InuYasha'', ''Manga/OnePiece'', ''Manga/{{Naruto}}'', ''Franchise/SailorMoon'', ''Manga/CardcaptorSakura'', ''Anime/PowerpuffGirlsZ'', ''Anime/FutariWaPrettyCure'', ''Anime/MermaidMelodyPichiPichiPitch'', ''Manga/AhMyGoddess'', ''Manga/LoveHina'', ''Anime/PetitePrincessYucie'', ''Literature/HaruhiSuzumiya'', ''Manga/NegimaMagisterNegiMagi'', ''Franchise/{{Pokemon}}'', ''Anime/DigimonTamers'', ''Franchise/YuGiOh'', ''Manga/ZatchBell'', ''Manga/RozenMaiden'', ''Franchise/TheLegendOfZelda'', ''VideoGame/StarOcean'', ''VideoGame/{{Xenogears}}'', the VideoGame/TalesSeries, ''Franchise/FinalFantasy'', and [[spoiler: Literature/{{Lolita}}. Yes, ''Lolita''.]]
248* The story ''The Terran Jedi'' over on Twisting The Hellmouth throws in many random cameos into a story where Xander is a Jedi Master, including but not limited to ''Franchise/StargateVerse, Discworld, Torchwood, Harry Potter,'' and ''{{Series/Frasier}}'' (of all things).
249** The ''Stargate'' parts have become so frequent and so large that they have long since gone beyond cameos, and at this point it reads like a straight crossover. The spin-off stories also make ''{{Series/NCIS}}'', ''{{Series/Haven}}'', and ''{{Series/Castle|2009}}'' part of this universe.
250* The ''Fanfic/ThereWasOnceAnAvengerFromKrypton'' series takes the Franchise/MarvelCinematicUniverse and adds other shows and movies into. To date, this includes ''WesternAnimation/TheOwlHouse'', ''WesternAnimation/GravityFalls'', ''Series/Supergirl2015'', ''WesternAnimation/Ben10'', ''Franchise/TalesOfArcadia'', ''WesternAnimation/MiraculousLadybug'', ''Literature/PercyJacksonAndTheOlympians'', ''WesternAnimation/DannyPhantom'', ''WesternAnimation/VoltronLegendaryDefender'', ''WesternAnimation/StevenUniverse'', ''WesternAnimation/SheRaAndThePrincessesOfPower'', ''Anime/DragonBallSuper'', and ''WesternAnimation/InfinityTrain''. And those are just the properties that get major focus, with allusions and references to even more scattered throughout.
251* [[http://browse.deviantart.com/?qh=§ion=&q=three+kingdoms+reimu#/d30b3nf The Three Kingdoms]] is another mega-crossover involving characters and objects from different game franchises, novels, movies and anime to suddenly start appearing in our world at December 21 2012, marking the Doomsday. After a short amount of joy, politics decided that these 'newcomers' were dangerous due to their magic capabilities, superior technology and other abilities. An event called Bad Apple Event led to [[http://touhou.wikia.com/wiki/Reimu_Hakurei Hakurei Reimu]] from the ''Franchise/TouhouProject'' video game franchise annexing the entire US which could be read on the prolouge. The Vocaloids and Miku eventually caught wind of the event and decided to annex other countries in the name of protecting them from Reimu. Of course, eventually, the kingdom of Gensokyo and Yamaha formed with war between them. They were soon joined by Haruhi no Suzumiya after realizing her god-like powers. By then, the three kingdoms have formed and the crossover 'The Three Kingdoms' led to Haruhi planning an invasion. This mega-crossover contains a variety of different creations (from HMS Thunderchild, Alex Mercer, Familiar of Zero, Star Wars, Strike Witches, Metal Gear and even One Piece).
252* ''TroperWorks/ThreeMessengers'' is somewhere between this trope and a Crossorgy. Production at present is slow because of how much there is that the author isn't sure about in one of the source works.
253* [=TKR2=], a now-defunct massive fanfic series by multiple authors started off as a fairly straight ''Series/KnightRider''/''Series/TeamKnightRider'' fanfic, then expanded to cross over with ''Franchise/StarWars'' (a lead character becomes a Jedi Master), then ''Franchise/StarTrek'' (another lead character becomes a ''Borg queen''--one episode has our heroes on a chase across dimensions, culminating in the Starship Voyager landing to help talking cars fight Darth Vader, while a young Creator/GeneRoddenberry, Glen Larson, and Creator/GeorgeLucas, who had apparently been out necking, look on), ''The Invisible Man'' (He gets a talking car), ''Franchise/{{Highlander}}'' (yet another character is an immortal--''and also a Jedi''), ''Hercules: The Legendary Journeys'' (In a very complex crossover, a character described as looking like Kevin Sorbo teams up with the real Kevin Sorbo, and also Hercules), ''Series/{{Teletubbies}}'' (They're evil aliens), ''Barney'' (He's ''A Great Old One''), Film/JamesBond (He teams up with our heroes to stop a supervillain plotting to ''build a giant lightsaber with which to cut the earth in half''), and ''Series/{{Survivor}}''. Really.
254* ''[[http://www.fortunecity.com/tinpan/johnette/139/tog.html Together Again]]'' by Chris Davies crosses over several anime, including ''Gall Force'', ''Anime/SailorMoon'', ''Anime/NeonGenesisEvangelion'', and many more, along with numerous non-anime sources including ''Franchise/StarWars'', ''TabletopGame/{{GURPS}} International Super Teams'' and DC's ''Sandman''.
255* While [[http://mega-poneo.deviantart.com/gallery/62840836/Tomica-Hero-Rescue-Pups Tomica Hero Rescue Pups]] stars characters from ''WesternAnimation/PawPatrol'' and ''Series/TomicaHeroRescueForce'', it's also very heavy on ''Franchise/StarWars'' and ''VideoGame/{{Bayonetta}}'' elements, complete with a Sith lord named Darth Longinus leading Neo Terror's remnant.
256* ''Fanfic/TheTooniverseEmissary'' [[https://www.fanfiction.net/s/11797963/]] is a homage to ''VideoGame/TheSubspaceEmissary'' (itself a Massive Multiplayer Crossover) that involves cartoons and anime series instead of video game series, as its title suggests. Series involved include ''WesternAnimation/SpongeBobSquarePants'', ''WesternAnimation/StarVsTheForcesOfEvil'', ''WesternAnimation/TheAmazingWorldOfGumball'', ''WesternAnimation/TheSimpsons'', ''WesternAnimation/PhineasAndFerb'', ''WesternAnimation/SouthPark'', ''WesternAnimation/FamilyGuy'', ''WesternAnimation/MiloMurphysLaw'', ''WesternAnimation/{{Pelswick}}'', ''WesternAnimation/ThePowerpuffGirls''... [[OverlyLongGag we could do this all day, you know]].
257* The story ''Toons'' takes place in a world where the characters of the author's favorite cartoons live. And that is a '''''lot''''' of shows, from the popular (eg ''Franchise/Ben10'') to the more obscure (eg ''WesternAnimation/{{Grossology}}''). [[https://www.fanfiction.net/s/10211960/1/Toons Here's the full list.]]
258* ''Fanfic/ToonZoneWrestling'' features the titular wrestling federation, which has an exceptionally eclectic roster. Said roster includes characters from: ''WesternAnimation/AdventureTime'', ''VideoGame/BackyardSports'', ''WesternAnimation/GravityFalls'', ''WesternAnimation/StevenUniverse'', ''Series/RobotWars'', ''VideoGame/{{Undertale}}'', and ''VideoGame/TonyHawksProSkater'', among other franchises, various [=YouTubers=], real-life athletes and celebrities, and [[OriginalGeneration characters from the creator's other projects]].
259* ''Fanfic/TopDog'', by Creator/DogheadThirteen, is a shared universe with several different storylines happening at once; the three main stories involve ''very'' AU versions of ''Literature/HarryPotter'', ''Manga/RanmaOneHalf'', and ''Manga/{{Naruto}}''. It pulls in characters and references from everywhere under the sun, including ''Anime/TenchiMuyo'', ''Series/{{Firefly}}'', ''Franchise/StarWars'', ''Franchise/StarTrek'', ''Webcomic/GirlGenius'', ''Webcomic/SluggyFreelance'', and more.
260* [[http://ideas.wikia.com/wiki/Torchic_and_Pals/Happy_Tree_Pokemons_and_Others Torchic and Pals]] has LOTS OF Characters such as Pokemon, Happy Tree Friends, Skylanders, Moshi Monsters and many, many other Characters!
261* The ''WesternAnimation/TotalDrama'' crossover fic ''Fanfic/TotalDramaCruise'' features characters from multiple series competing together.
262** The first season has [[WesternAnimation/TotalDrama Sammy, Lindsay, Dawn, Eva, Scott, DJ]], [[WesternAnimation/EdEddNEddy Eddy, Rolf]], [[Anime/PokemonTheSeries Ash Ketchum, Clemont]], [[Manga/MyHeroAcademia Fumikage Tokoyami]], [[Literature/KonoSuba Aqua]], [[WesternAnimation/GravityFalls Wendy Corduroy]], [[Anime/PantyAndStockingWithGarterbelt Stocking]], [[Anime/KillLaKill Ryuko Matoi, Mako Mankanshoku]], [[WesternAnimation/WackyRaces Peter Perfect]], [[Anime/AttackOnTitan Armin Arlert]], [[WesternAnimation/TheSecretOfKells Brendan]], [[Literature/GoblinSlayer Priestess]], [[WesternAnimation/{{Metalocalypse}} Murderface]], [[VisualNovel/CorpseParty Satoshi, Yuka]], [[WesternAnimation/Hero108 Mighty Ray]], [[WesternAnimation/AmericanDad Terry Bates]], [[WesternAnimation/TeenageMutantNinjaTurtles2012 Michaelangelo]] and [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 Beast-Man]].

273* [[http://traitorgame.wikia.com/ The Traitor Game]] is like CLUE. Except with various fictional characters dropped into a setting and violently murdering people amidst a usually epic background. So far, we've had Trigon getting beat up by [[Anime/NeonGenesisEvangelion Asuka, Rei,]] [[Franchise/{{Superman}} Cyborg Superman]], [[ComicBook/Marvel2099 Doctor Doom 2099]], and a slew of others by the usage of Yellow Lantern rings... actually, just go read the summaries there.
274* ''Roleplay/TheTravelsverse'' is a collection of both Nintendo and other game series that are connected via Super Smash Brothers, by Bulbagarden Member Instrutilus. Though a majority of the action seem takes place on Sinumonas, the name of the Pokémon World here, the person in charge, Instrutilus, has expressed interest in looking at other series to help connect the universe, rather then just having [[CrossoverShip Link and Samus]] live on the planet and several references to the Super Smash Brothers Core, a collection of the universes greatest fighters that was named after an old tournament they once participated in.
275* ''[[http://psychoe.deviantart.com/art/TCD-prologue-27019744 TRES]]'' is a lesser-known webcomic which stars several characters from different anime and has a ''Manga/TsubasaReservoirChronicle'' influence.
276* ''Wrestling/UltimateCrossoverWrestling'' combines not just wrestling organizations (WWE, TNA, etc), but anime, games, tv and movies.
277* ''[[https://www.fanfiction.net/s/2899225/1/Ultimate-Smash-Adventure Ultimate Smash Adventure]]'' involves the Videogame/SuperSmashBros fighters both the original game and Melee (plus only a few of the Newcomers that appear in Brawl, as the fic itself was written and completed while Brawl was still under development) working as a Justice League-esique team dedicated to protecting the multiverse. They travel several to worlds and fight villains from various video game and anime worlds (such as VideoGame/TalesofSymphonia, or Manga/OnePiece), as well as even the [[ComicBook/UltimateMarvel Ultimate Marvel universe]].
278* ''FanFic/UndocumentedFeatures'', created by Creator/EyrieProductionsUnlimited. This story is more or less continually written since the early 1990s by a dedicated creative team, running into many many megabytes of stories. ''UF'' blends together so many sources that ''no one'' has a definitive count of them, and has successfully combined them all into a single galaxy-spanning space opera epic with an internal history of thousands of years. The earlier works are admittedly crude -- the first installment was intended as a joking "we could do something like this" example meant to be discarded when the "real" writing began -- but ''UF'' (and other EPU) stories since the middle to late 1990s have all been of exceptional quality and workmanship.
279** Also by the fine folks at EPU, ''Fanfic/NeonExodusEvangelion'' starts off looking like just an ambitious AlternateUniverseFic for ''Anime/NeonGenesisEvangelion'', but before long it becomes clear that this is a MassiveMultiplayerCrossover world involving at least a dozen sources besides ''NGE'', and that it only tangentially ''resembles'' {{canon}} ''Evangelion''. Interesting to note that, much as ''Evangelion'' was a {{deconstruction}}, ''Neon Exodus Evangelion'' is a deconstruction of what the authors felt was the meaningless nihilism of the original, and the fic can be somewhat hard to warm to.
280* ''Fanfic/UnexpectedEncounters'' (MassiveMultiplayerCrossover with ''Anime/{{Aggretsuko}}'' and ''Anime/SonicX'', with some cameos from characters from other sagas such as ''Manga/{{Beastars}}'', ''Franchise/StarFox'', ''Literature/KaiketsuZorori'', ''WebAnimation/HappyTreeFriends'', and ''Franchise/RatchetAndClank''). The characters from ''WesternAnimation/{{Zootopia}}'', ''Aggretsuko'', ''Kaiketsu Zorori'', ''Star Fox'' and ''Ratchet & Clank'' belong to the same universe, while the characters from ''Sonic X'', ''Beastars'' and ''Happy Tree Friends'' come from three different dimensions.
281* ''[[http://www.sfdebris.com/unity.asp Unity]]'' is for the most part simply a crossover between ''Franchise/StarWars'' and ''Franchise/StarTrek'', albeit an exceptionally large and epic one. Then suddenly its last few chapters involve Seven of Nine and Mara Jade crossing into all kinds of other franchises: ''Franchise/{{Halo}}'', ''Franchise/{{Hellraiser}}'', ''VideoGame/WingCommander'' (where they note the resemblance a character played by Mark Hamill has to Luke), ''Film/NightOfTheLivingDead1968'', ''Literature/TheWarOfTheWorlds'', the Franchise/MarvelUniverse, ''Franchise/{{Transformers}}'', ''Literature/TheLordOfTheRings'', ''Franchise/TheHitchhikersGuideToTheGalaxy'', ''Franchise/{{Alien}},'' and ''Series/{{Battlestar Galactica|2003}}''. After that last one, Number Six even tags along and plays a key role in the final battle.
282* ''Fanfic/UnityForce'' by [[https://www.fanfiction.net/~meetoureyes meetoureyes]] features a ragtag of characters in all forms of media that includes animes, TV series, video games, etc. They are sent to the multiverse to either protect the worlds from getting destroyed or to lend a helping hand to someone's problems. The heroes all situate in a place known as the Unity Force Academy in Unity Force Earth.
283* Creator/{{Vathara}}'s Urban Legends universe, which includes or alludes to easily twenty or more series.
284* ''[[http://www.fanfiction.net/s/93246/1/ The Virus]]'', by Chris Jones. This short story--which was a originally a simple crossover between ''Manga/RanmaOneHalf'' and ''Anime/TenchiMuyo'' with a few cameos from other series--expanded unexpectedly into [[http://web.archive.org/web/20051228140921/furinkan.net/display.php?pageid=11 a shared-world megacrossover]] where characters from dozens of fandoms had to deal with the after effects of a Juraian virus which had incorporated Ranma's gender-bending curse into itself, and then transmitted it ''permanently'' to ''every living human''.
285* ''Fanfic/{{Vigil}}'' is a combination of this and a FusionFic that rolls together the settings of ''Franchise/MassEffect'', ''Videogame/XCOMEnemyUnknown'', ''Videogame/{{FEAR}}'', ''Tabletopgame/EclipsePhase'', and ''Videogame/{{Destiny}}'', with elements of ''Videogame/SidMeiersAlphaCentauri'' and ''Franchise/{{Terminator}}'' for good measure.
286* ''Fanfic/WhenLegendsMeet'' is a crossover between various properties- ''Literature/TolkiensLegendarium'', ''Franchise/MarvelCinematicUniverse'', ''Franchise/StarWars'', ''Franchise/{{Buffyverse}}'', ''Series/{{Smallville}}'', ''Series/{{Supernatural}}'', ''Franchise/{{Arrowverse}}'', ''Franchise/KingdomHearts'', ''Franchise/CompilationOfFinalFantasyVII'' and ''Franchise/DragonBall'' to name a few.
287* ''FanFic/WhereOnEarthSpies'' is a WebSerialNovel that began as a crossover between ''[[Literature/WheresWally Where's Waldo]]'' and ''Franchise/CarmenSandiego'' in which they are the best agents at two competing secret agencies. FoeYayShipping Ensues. After the first chapters, the author expanded into other properties, incorporating (among others) the GEICO Gecko, Advertising/ErinEsurance, and Allstate's Mayhem. It can be found [[http://pentharis.deviantart.com/gallery/?offset=24#/d4bjjwf here]].
288* ''Fanfic/WhotrekTheUltimateAdventure1'' starts out as just a crossover between Franchise/StarTrek and Series/DoctorWho, but it quickly turns into one of these.
289* In an example from the 1990s, "The Witness" by Michele Martin combines Series/{{Highlander}}, Series/ForeverKnight, Series/QuantumLeap, Series/TheXFiles, and Series/{{Starman}}, in an admirably coherent plot with accurate characterization. Several other series make brief cameos.
290* ''FanFic/WithASnap'' takes place after the events of Film/AvengersInfinityWar. Thanos’ snap not only affected the MCU, but every universe and reality. Other heroes from other universe join the Avengers as they search for Thanos, and a way to undo the snap. This is a massive crossover between the MCU and various series including, but not limited to: WesternAnimation/{{Ben 10}}, WesternAnimation/MiraculousLadybug, WesternAnimation/DannyPhantom, WesternAnimation/MyLifeAsATeenageRobot, WesternAnimation/SymBionicTitan, WesternAnimation/KimPossible, WesternAnimation/TheSecretSaturdays, WesternAnimation/ElTigreTheAdventuresOfMannyRivera, WesternAnimation/OKKOLetsBeHeroes, WesternAnimation/SheRaAndThePrincessesOfPower, WesternAnimation/TransformersAnimated, Franchise/PowerRangers, Series/DoctorWho, Series/StargateSG1, Literature/ACertainMagicalIndex, and Webcomic/OnePunchMan.
291* The series ''Fanfic/WithPearlAndRubyGlowing'' is about characters from several different movies and shows attending a sexual assault support group. Initially, it started out with just media from Franchise/DisneyAnimatedCanon, but it eventually expanded to other types of children's animated media, with even live-action shows, movies, and musicals getting thrown into the mix. There are plans to include adult-animated shows in a future spin-off.
292* ''Fanfic/WithThisRing'' is primarily a ''WesternAnimation/YoungJustice'' fanfic, but it includes occasional snippets of alternate versions of the main character in other universes, from ''TabletopGame/WarhammerFantasy'', to ''Literature/{{Gate}}'', to ''Manga/DeathNote'', to ''WesternAnimation/CaptainPlanet'', and many more. On occasion, they even interact with the main storyline; the ''WesternAnimation/Thundercats2011'' protagonist was a key part of [[spoiler:defeating Krona]], and the Renegade protagonist dates [[WesternAnimation/MyLittlePonyFriendshipIsMagic Luna]].
293* ''FanFic/TheWorldOfTheCreatures'': Takes place inside a fan's head, so various characters from different franchises get to meet - Most notably Franchise/{{Batman}}, [[Series/BuffytheVampireSlayer Buffy Summers]], and [[Series/DoctorWho The Doctor]]
294* Years ago there was a combination fanfic/webcomic called ''The Wrath of Invincar''. The main characters of ''Literature/{{Slayers}}'' and ''Anime/TheVisionOfEscaflowne'', who had been placed in a ''Gilligan's Island''-esque setting, set out on a quest to defeat...a green Smurf, with [[HilarityEnsues hilarity ensuing]] along the way. Such antics included Gaav settling an argument with Phibrizzo by pinning him beneath [[Franchise/ScoobyDoo the Mystery Machine]]; much mockery by the [[Film/MontyPythonAndTheHolyGrail French knights]]; and a showdown between Lina Inverse and WesternAnimation/QuickDrawMcGraw. Sadly, the story has since been taken off the Internet for space reasons.
295* ''Fanfic/YouGotHaruhiRolled'' usually isn't a crossover, but the court case arc has the conceit that all characters from all fiction exist in the same CityOfAdventure, so the author included cameos from every fictional universe he could think of.
296* ''Fanfic/YuYuGiDigiMoon'' is an ambitious crossover between ''Manga/YuYuHakusho, Franchise/YuGiOh, Anime/DigimonTamers, Anime/DigimonFrontier'' and ''Franchise/SailorMoon''. Later stories include ''Anime/DigimonAdventure, Anime/DigimonAdventure02, Anime/YuGiOhGX'' and ''Anime/YuGiOh5Ds''.
297* Curtis Wildcat's ''[[https://archiveofourown.org/works/27736435/chapters/67887550 Zero Context: Taking Out the Trash]]'' is set in a ScienceFantasy world called Muffinville, home to all sorts of both scientific and magical odds and ends. The protagonists include [[VideoGame/KidIcarusUprising the Goddess of Nature and her chief lieutenant]], [[Anime/PowerpuffGirlsZ Kaoru Matsubara]], a sentient doll of [[Literature/{{Slayers}} Lina Inverse]] and a trio of [[Franchise/{{Pokemon}} Pokémon]]; another protagonist uses a [[VideoGame/{{Descent}} Pyro-GX starship]] to get from place to place, a meeting early in the story is held in an [[Franchise/StarWarsLegends Eclipse-class Star Dreadnaught]] repurposed as a restaurant, and the main antagonist uses a [[ComicBook/IronMan "dark-toned Hulkbuster rip-off"]] to help him fight... and that's just for starters.

300!!Other fan works:
301
302[[folder:Fan Games]]
303* ''VideoGame/AbobosBigAdventure'' has characters and elements from several dozen NES games mashed together.
304* ''VideoGame/BrutalMario'' has Mario crossover with Final Fantasy Tactics, Kirby, Mega Man Classic, World of Mana, ''VideoGame/SaGaRPG'' and much more.
305* ''[[VideoGame/CardSagaWars Card Sagas Wars]]'' ([[http://cardgallery.tales-tra.com/main_csw.htm see here]]) is another ambitious fangame, combining many characters from several different games. It's the sort of thing that can only exist due to dedicated fans or else the legalities of it would make ''everyone's'' heads spin.
306* ''VideoGame/CMCPlus'' is a ''VideoGame/SuperSmashBrosCrusade'' modification that includes many different franchises and characters (over '''200''' playable) in the PlatformFighter setting. Including veteran fighters from the vanilla game, plus some extra newcomers from their respective company/franchises; other IP's from games and non-games previously unassociated with ''Crusade''; and truly oddball additions that can only happen in a CrackFic setting (UsefulNotes/BarackObama, [[UsefulNotes/KentuckyFriedChicken Colonel Sanders]], and [[UsefulNotes/McDonalds Ronald McDonald]]).
307* [[http://gokou-sama.deviantart.com/ Gokou Sama (aka Somarinoa or Thor Steinbach)]] is currently working on the following MassiveMultiplayerCrossover Video Games: [[http://ultimateshowdowns.wikia.com/wiki/Ultimate_Showdown Ultimate Showdown]] (top down action game about characters from everything engages massive duel of death) and [[http://ultimateshowdowns.wikia.com/wiki/Amalgam_Online Amalgam Online]](Alien-themed MassiveMultiplayerCrossover Strategy game)
308* ''VideoGame/GwangeDash'', an indie [[BulletHell shmup]] featuring ships, enemies and bosses from a lot of different shooters, including ''[[VideoGame/DonPachi DoDonPachi]]'', ''VideoGame/{{Guwange}}'', ''VideoGame/{{Ketsui}}'', ''VideoGame/{{Ikaruga}}'', ''VideoGame/TwinCobra'', ''VideoGame/{{Gradius}}'', ''VideoGame/BattleGaregga'', ''VideoGame/RadiantSilvergun'' and countless more.
309* ''VideoGame/HappyTreeFriendsAdventures'', a series of platformer games starring the titular WebAnimation/HappyTreeFriends and [[Franchise/SuperMarioBros Bowser]] (and his usual minions from his home franchise). However, it also features other characters, music, and elements from other franchises. Those franchises include ''VideoGame/{{Contra}}'', ''VideoGame/TwinBee'', ''Franchise/MegaMan'', ''VideoGame/{{Gradius}}'', among others. It also helps that currently the series has a large cast.
310* ''[[https://www.wattpad.com/1158324255-interdimensional-academy Interdimensional Academy]]'' starts off with various characters from ''VideoGame/{{Deltarune}}'', ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', ''Music/{{VOCALOID}}'' and ''Manga/MissKobayashisDragonMaid'' attending a magical school together, and adds characters from [[spoiler: VideoGame/{{Danganronpa}} and VideoGame/{{OMORI}}]] in the most recent chapters, as well as a few characters that weren't mentioned earlier.
311* ''VideoGame/Mari0'' takes the original ''{{VideoGame/Super Mario Bros|1}}.'' and gives Mario a Videogame/{{Portal}} gun. It also includes a ''{{VideoGame/Minecraft}}'' mode.
312* ''VideoGame/MushroomKingdomFusion'', a [[http://s4.zetaboards.com/mkfusion/index/ fangame-in-progress]], sends Mario and Luigi (later a host of others) across a few of the most famous gaming franchises in order to bring down [[Franchise/{{Castlevania}} Legion]] before he can successfully fuse all worlds and drain the energy from the reaction... or something. The creators are keeping the plot a secret--will they finish before it becomes the gaming equivalent of a DeadFic? Given the ambition of the project, it unfortunately did not... but hey, [[VideoGame/MetalGear Solid Snake]] is mentoring them! If that doesn't make it awesome, what does?
313** Its sister project ''VideoGame/SuperMarioFusionRevival'', though more Mario-centric (as in, only Mario and Peach thus far are playable characters), still features levels and areas from many other franchises once outside the first world. A smaller and less ambitious project then MKF, but built with a stronger engine and with great care put into each stage. [[http://youtu.be/0wDHsFnTzQk Take a look for yourselves.]]
314* ''VideoGame/RakenzarnTales'' is shooting for this. Its world, Rakenzarn, claims to be home to all fictional characters and incorporates a huge number of characters, either playable or as [=NPCs=]. While popular ones like Mario, Sonic, Naruto and Deadpool aren't too surprising, there are lesser-known and unlikely ones like [[Manga/UFOBaby Kanata Saionji]], [[Manga/UltraManiac Nina Sakura]], Manga/{{Himawari}}, and VideoGame/{{Tomba}}.
315* ''Super Mario RPG: Armaggeddon'' is a crossover ROM hack of ''VideoGame/SuperMarioRPG'' that allows Mario's team to fight various characters from the ''Franchise/FinalFantasy'' and ''Franchise/{{Pokemon}}'' franchises, as well as engage in battle with [[VideoGame/ChronoTrigger Magus]]. In this game, defeating Tonberries gives you armor that absorbs certain elements.
316* ''VideoGame/TerrordromeTheGameRiseOfTheBoogeymen'' is a fighting game featuring characters from thirteen[[note]](''Film/TheTexasChainsawMassacre'', ''Franchise/ANightmareOnElmStreet'', ''Franchise/EvilDead'', ''Franchise/{{Halloween}}'', ''Film/ChildsPlay'', ''Franchise/FridayThe13th'', ''Film/{{Scream}}'', ''Film/{{Phantasm}}'', ''Film/ManiacCop'', ''Film/{{Candyman}}'', ''Film/ReAnimator'', ''Franchise/{{Hellraiser}}'' and ''Film/{{Pumpkinhead}}'')[[/note]] different horror movie franchises.
317* ''[[VideoGame/XenoFighters Xeno Fighters R]]'', a BulletHell Shmup featuring ships and characters from ''VideoGame/{{Gradius}}'', ''VideoGame/{{Raiden}}'', ''Legendary Wings'', ''Twinbee'', ''Galaga'', and more.

321* [[https://www.youtube.com/watch?v=5iVJEijl8lQ Crossover World]]. Saying anything else would ruin it.
322* The granddaddy of all {{Fan Vid}}s is the [[https://www.youtube.com/watch?v=-840keiiFDE Daicon IV Opening]], made for a Japanese anime convention in 1983 by a group who would go on to become Creator/StudioGainax. It's impossible to list (although [[http://web.archive.org/web/20071016064255/http://www.anime-classic.net/AC/modules/wiwimod/index.php?page=DaiconWiki&back=WiwiHome somebody tried]]) all the sci-fi, fantasy, movie, comic book and game references found in these five incredibly animated minutes.
323* ''WebAnimation/DeadFantasy'' unites (mostly) female characters from ''Franchise/FinalFantasy'', ''Franchise/KingdomHearts'', and ''VideoGame/NinjaGaiden'' as they end up having to fight each other in very brutal ways.
324* [[https://www.youtube.com/c/HatLovingGamer Hat-LovingGamer]]'s video, ''[[https://www.youtube.com/watch?v=vB0vVR6OwF8 I thought this was Sonic 2]]'' begins with the FinalBoss fight of ''VideoGame/SonicTheHedgehog2'', and every time the Death Egg Robot is hit, the entire franchise changes, replacing Sonic and the robot with another hero and villain, all rendered and animated in the style of Sonic: [[VideoGame/SuperMarioBros2 Mario and Birdo]], [[Franchise/TheLegendOfZelda Link and Ganondorf]], [[Franchise/{{Kirby}} Kirby and King Dedede]], VideoGame/CrashBandicoot and Dr. Cortex, etc. It eventually cycles back to ''Sonic 2'' but with Eggman as the hero and Sonic as the robot, before being defeated. [[https://www.youtube.com/playlist?list=PLVS15h7xpPFYzGxlWgF2jsCcbua0_bCIG Each subsequent video]] starts with a different ''Sonic'' protagonist (Tails, Knuckles, Amy, etc) but follows a similar formula with more franchises being added.
325* In episode 6 of ''WebVideo/KOnTheAbridgedSeries'' when Yui loses her voice, Ritsu asks several other abridged characters if they know where Yui's voice is, characters such as Abridged Taiga, Abridged Tristan, Abridged Nagisa, Abridged Potato, Abridged Rin, and even Abridged ABRIDGED Ritsu.
326* Niconico video list [[http://www.nicovideo.jp/mylist/16424696 Muv-Luv Crossovers]], blends the ''Unlimited'' storyline of ''Franchise/MuvLuv'', and splices it with the ''VideoGame/GunparadeMarch'' universe, in addition to having characters from ''Anime/{{Zegapain}}.'' Running parallel to the story is the Planet Faery setting of ''Literature/SentouYouseiYukikaze'', in which [[Anime/ArgentoSoma Ryu Sohma]] becomes the copilot to Rei Fukai after his transformation from Takuto Kaneshiro. And both worlds are fighting what seemed to be a combination of JAM, BETA, and/or [[Anime/SoukyuuNoFafner Festum]], and it seems that [[spoiler:Sumika is the AI core of Yukikaze, linking the two worlds]]. The story is told in VisualNovel-style dialogues interspersed with footages from anime/games related to the media, as well as careful splicing to ensure that everything is consistent. The "opening" animation of the series proper is in the second episode, but while it starts with Muv-Luv setting and the beginning of Argento Soma, Yukikaze's arc proper starts at episode 6. As of 12 February 2011, the series has 10 episodes ranging from 20 to 30 minutes. Unfortunately, since the series is very heavy on dialogues, non-Japanese speaking viewers would have quite a problem in following it.
327* Many VideoGame/{{MUGEN}} video series on [=YouTube=], when they're not just series of fights, will be a MassiveMultiplayerCrossover, such as:
328** The 7th Moon MUGEN series by [[https://www.youtube.com/user/angeldagdag angeldagdag]]
329** The WebAnimation/HvHMUGEN series by [[https://www.youtube.com/user/solkenneth003 solkenneth003]]
330** DRB Origins, ODC Wisdom and ECE Mystery by [[https://www.youtube.com/user/TheOfficialFallen TheOfficialFallen]]
331* ''[[https://www.youtube.com/watch?v=RB74RUZO9ZI Phoenix Wright Anime Attorney]]'' is an AMV that's edited in a way that makes it seem as though Phoenix Wright is interacting with characters from various other anime series.
332* A mixed-negative example: the infamous cringe-worthy ''WebVideo/PoohsAdventures'' series would count as this, albeit VERY poorly executed. It's done this to the point where it's [[http://poohadventures.wikia.com/wiki/Pooh%27s_Adventures_of_Scooby-Doo_and_the_Ghoul_School downright unhealthy]].
333* [[https://www.youtube.com/watch?v=QeMNekTCpYw The Pursuit of Happiness]] is a crossover between ''abridged series'', featuring ''WebVideo/NullmetalAlchemist'', ''WebVideo/CodeMent'', ''Soul Whatever'', ''WebVideo/NonePiece'', and ''WebVideo/DanganRonpaAbridgedThing''.
334* The [=Disney/NonDisney=] editor community on [=YouTube=] does this often in their videos but seem to be having their own crossover event with a project called ''[[https://www.youtube.com/watch?v=6ugAPnosQ20 The Sixth Sense]]''. It involves an amalgam of plots reminiscent of ''X-Men'', witch hunts, government conspiracies, giving various animated characters powers and having them interact. Already, people have mini-storylines and connections to other characters which will probably continue into the official project.
335** It has also inspired a fanfiction which can be read [[http://www.fanfiction.net/s/6338303/1/The_Sixth_Sense here]], though it is sadly no longer up.
336* ''WebAnimation/Supermarioglitchy4sSuperMario64Bloopers'' started out as simple videos with the ''Franchise/SuperMarioBros'' cast, but as time went on characters from ''Franchise/{{Pokemon}}'', ''VideoGame/{{Minecraft}}'', ''Series/{{Teletubbies}}'', ''Franchise/SonicTheHedgehog'', ''Franchise/TheLegendOfZelda'', ''Franchise/{{Splatoon}}'', and even some original characters joined in.
337* ''WebVideo/TheUltimateEdChronicles'' is this to an absurd degree. The first film featured ''[[WesternAnimation/EdEddNEddy the Eds]]'' teaming up with ''Franchise/KingdomHearts'' characters and [[Film/TransformersFilmSeries the Autobots]] to take down the combined forces of [[WesternAnimation/SleepingBeauty Maleficent]] and the Decepticons, and that's only the ''beginning''.
338* The Music/UltimateShowdownOfUltimateDestiny.
339* There exists a small community of [=YouTubers=], some taking on the identities of fictional characters, who specialize in editing together massive crossover videos. Despite how their videos appear, they try not to use the ''Pooh[='=]s Adventures'' formula, instead trying to craft original stories or making movie parodies (taking the dialogue of various films/trailers and dubbing them over clips of their favorite fictional characters, who play the parts of the characters in the original work). Members of this community include [[https://www.youtube.com/channel/UC4fycBtIaFX9X5eN7JWT--A Ren the God of Humor]], [[https://www.youtube.com/user/brermeerkat Aaron the Viking Meerkat]], [[https://www.youtube.com/user/PrincessRapunzel18 Princess Rapunzel]], [[https://www.youtube.com/channel/UCiHmNShh8EEjkl7VOgeLyLA The Misfitz]], [[https://www.youtube.com/channel/UCPxlDDBoAsWShr367QYHv1g Princess Twilight Sparkle]], [[https://www.youtube.com/user/Jke130 Jessica Espinoza]], and various others.
