History CrossOver / FanWorks

* ''Fanfic/TheAmazingSpiderLuzInAcrossTheOwlVerse'' is a crossover of ''WesternAnimation/TheOwlHouse'' and ''Franchise/SpiderMan''where Luz has Spider-Man's powers.

{{Crossover}}s are huge in all fanworks, and some of the biggest reasons to create them. Without pesky things like UsefulNotes/{{Copyright}}s or UsefulNotes/{{Trademark}}s, it's incredibly easy to combine any and all works together.

* Originally, the intent was for ''Fanfic/MyBravePonyStarfleetMagic''; to be completely separate from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', but eventually it became a crossover, and then was fully integrated into a ''Franchise/MyLittlePony'' story.

* ''Fanfic/ACertainMagicalFriendship'' crosses ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' with ''LightNovel/ACertainMagicalIndex'' using a magic portal that rebuilds characters as they move between the two settings. In Academy City, Twilight is a human cabal magician. In Ponyvile, Misaka is a pegasus who likes to keep lightning bolts in her fur. Which is fine, right up until villains start moving between the two worlds as well...

* ''Fanfic/TheCriesOfHaruhiSuzumiya'' is a crossover between ''LightNovel/HaruhiSuzumiya'' and ''VisualNovel/HigurashiWhenTheyCry''.

* ''Fanfic/KyonBigDamnHero'' manages to become a crossover between LightNovel/HaruhiSuzumiya and ''Website/TvTropes'', with ''VisualNovel/HigurashiWhenTheyCry'' and bits of [[spoiler:''VideoGame/HalfLife'']] added in as well.

* ''Fanfic/TheShieldsDragon'' takes ''VideoGame/{{Yakuza}}''-series protagonist Kiryu Kazuma [[spoiler:post-''VideoGame/Yakuza6'']] and transports him to the world of ''LightNovel/TheRisingOfTheShieldHero'', with his fighting-styles converted into the world's SuddenGameInterface. Ass-kicking ensues.

* These [[https://www.youtube.com/watch?v=O2sUOlf-DVs two]] [[https://www.youtube.com/watch?v=0SRUCfgSj_0 videos]] make a sort of crossover between ''Manga/LuckyStar'' and ''LightNovel/HaruhiSuzumiya''.

** ''Fanfic/TheHillOfSwords'', a ''LightNovel/TheFamiliarOfZero'' crossover wherein Louise summons Shirou as her familiar. This FanFic revived the whole concept of "Let's have Louise summon a different person than Saito !"

* ''Fanfic/SpinelsNewBestFriend'': A crossover between ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' and ''WesternAnimation/StevenUniverse'' set at the end of [[WesternAnimation/StevenUniverseTheMovie the movie]], where Spinel decides to run away after everything she did, deciding she's done too much to deserve forgiveness. She takes the warp pad to some random planet and rejuvenates herself... and is given to Pinkie Pie as a gift, and becomes her new friend.

* ''Fanfic/PokemonCrossingFlyMeToTheMoon'': ''VideoGame/AnimalCrossing'' villagers live in the ''Franchise/{{Pokemon}}'' world; several villagers become trainers, gym leaders, or join villainous teams.

* ''Fanfic/TheDragonAndTheButterfly'' is a crossover fic between ''WesternAnimation/HowToTrainYourDragon'' and ''WesternAnimation/Encanto''. Here, Hiccup and Toothless left the archipelago before the former learned about the dragon nest. While searching for a new home, the two are caught in a storm and land in a magical part of Colombia...

* ''Fanfic/GodsAngelsAndKings'', aka ''Hail to the King'', is a crossover between ''Franchise/{{Godzilla}}'' and ''Anime/NeonGenesisEvangelion'', using a amalgamated continuity for the former that also incorporates ''Series/ZoneFighter''. The rewrite replaces Zone Fighter with Series/{{Ultraman}}.

* ''Object Shows Unite'' is a crossover between many different ObjectShows [[note]]''WebAnimation/BattleForDreamIsland'', ''WebAnimation/InanimateInsanity'', ''WebAnimation/ObjectUniverse'', ''WebAnimation/ObjectMayhem'', ''Inanimate Fight-Out'', ''WebAnimation/ChallengeToWin'', ''WebAnimation/BrawlOfTheObjects'', ''WebAnimation/ObjectOverload'', ''The Strive for the Million'', ''Object Illusion'', ''WebAnimation/ObjectLand'', ''Next Top Thingy'', ''WebAnimation/ObjectHavoc'', ''Object Insanity'', ''WebAnimation/BrawlForObjectPalace'', ''WebAnimation/ObjectLockdown'' and ''Lockout'', ''[[WebAnimation/PaperPuppets Paper Puppets Take 2]]'', ''WebAnimation/ObjectMadness'', ''WebAnimation/ObjectInvasion'', ''WebAnimation/ObjectTerror'', ''WebAnimation/ObjectConnects'', ''[[WebAnimation/ObjectFiller Object Filler Again]]'', ''WebAnimation/YetAnotherGameshow'', ''Battle for the Respect of Roboty'', ''WebAnimation/UltimateInsanity'', ''WebAnimation/ModernObjects'', ''WebAnimation/OpenSourceObjects'', ''Nonexistent Living'', ''WebAnimation/AnimatedInanimateBattle'', ''Incredible Items'', and ''The Object Project''[[/note]] as well as the author's own OriginalCharacters.

** There's a small collection of ComicStrip/CalvinAndHobbes[=/=]Literature/HarryPotter crossovers, all involving Calvin being a wizard. Luckily this corner of fan fiction seems to be untouched by SturgeonsLaw, although that may be because they're so small in number. [[http://www.fanfiction.net/Harry_Potter_and_Calvin_Hobbes_Crossovers/224/266/ Give em a look.]] [[http://www.fanfiction.net/s/6548722/1/Calvin_and_Hobbes_in_the_Wizarding_World This one is particularly good so far.]]

* Decent [[http://www.fanfiction.net/Pokemon_and_Digimon_Crossovers/80/257/ Pokemon/Digimon crossovers]] are not that common in fanfiction, but of late some interesting new submissions have popped up. SturgeonsLaw may be applicable due to grammar issues, but those with decent grammar tend to be alright.

* Literature/TheWTFJournal crosses over at least five fandoms.

''Fanfic/ShatteredSkiesTheMorningLights'': By the same author as ''FanFic/StarsAbove'' and ''FanFic/{{Respect}}'' below, this is a full-blown CrisisCrossover that brings together the casts of ''Franchise/SailorMoon'', ''Manga/CardcaptorSakura'', the ''Anime/PrettyCure'' metaseries, ''Franchise/LyricalNanoha'', and ''Franchise/MadokaMagica'' to try to save their universes and all of reality.

* ''[[https://www.fanfiction.net/s/3510991/1/One-Piece-A-Smash-Adventure One Piece: A Smash Adventure]]'' by [[https://www.fanfiction.net/u/794512/Specter24 Spectre24]] has ''Manga/OnePiece'' characters crossover with various Nintendo franchises related to ''VideoGame/SuperSmashBros''.
** Due to its increased popularity, other users have attempted to make similar crossovers based on this. Most notable is [[https://www.fanfiction.net/u/447022/Game2002 Game2002]] who basically took the same concept, this time with ''Touhou'' characters. His [[https://www.fanfiction.net/s/5681268/1/Touhou-Journey-to-the-Smashing-Beyond crossover]] was also a huge hit among fans.

* Fanfic/KhaosOmega uses this prominently by sending someone (usually the [[ArtifactTitle titular]] [[RedBaron Amethyst Angel]], a modified version of [[VideoGame/GalaxyAngel Galaxy Angel II's]] [[DarkSkinnedRedhead Anise Azeat]]) to another game's world. With a massive dose of multiverse theory on top of it, and a faction of immortal multiverse-traveling crime fighters (of whom the aforementioned Amethyst Angel is a high-ranking member, and founded by six siblings (five of whom are based on real-life people Khaos knows including third-oldest Jet being based on Khaos himself), things can go crazy insanely fast.[[/index]]]

*** "Voldemort has found a way to go back [[ArtisticLicensePaleontology thousands of years]], to the time of the great dinosaurs"? That's not a promising opening line. There's even a [[http://www.fanfiction.net/s/5426174/1/ Land Before Time MassiveMultiplayerCrossover series on FanFiction.net.]] Too bad [[SturgeonsLaw it's about the same as 90% of all fanfics.]]

* ''Fanfic/WaterAerobicsForTheAquaphobic'' centers on most of Hogwarts' student body (and a couple of Death Eaters) being cursed into various forms after Umbridge brings them on a poorly-thought-out field trip to Jusenkyo from ''Manga/RanmaOneHalf''. [[VideoGame/TombRaider Lara Croft]] is also mentioned in passing as giving no end of trouble to the Gringotts employees in Egypt.

* ''[[http://archiveofourown.org/works/10027490 Operation Epic Beer Run]]'' and ''[[http://archiveofourown.org/works/10027490 And Miles To Go Before I Sleep]]'' cross ''Film/TheMartian'' with the Franchise/MarvelCinematicUniverse via [[spoiler: Dr. Beck being one of Bucky Barnes's descendants]].
