History CrossOver / FanWorks

* ''Fanfic/PointMeAtTheSkyrim'' is a crossover between ''Literature/{{Ward}}'' and ''VideoGame/TheElderScrollsVSkyrim'', with the superhero Antares (aka Victoria Dallon) awakening on the cart to Helgen with no memory of how she got there.

* ''Fanfic/DungeonKeeperAmi'' is an improbable mix of ''VideoGame/DungeonKeeper'' and ''Anime/SailorMoon''. And quite good.

{{Crossover}}s are huge in all fanworks, and some 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.

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

* ''WebAnimation/ZanyToTheMax'' has an episode where the Warners (it's an ''WesternAnimation/{{Animaniacs}}'' fan series) enter the world of ''Literature/TheTimeMachine'' and try to help the Time Traveler find Weena as part of a contest. If they win, they will be able to [[ImTakingHerHomeWithMe take Weena home with them]]. [[spoiler: They don't win. WebAnimation/{{Homest|arRunner}}ripe [[AuthorAvatar Runner]] does instead.]] The episode is implied to turn into a MassiveMultiplayerCrossover by the end.\\
--> '''News Reporter:''' We just got reports of [[WesternAnimation/ThePowerpuffGirls three super-powered sisters from the city of Townsville, Animenia]], in the Warner Bros. studio.\\
'''Yakko:''' Super-powered sisters? Townsville, Animenia? [[BorrowedCatchPhrase Yes!]] Come, Warners. We must prepare for tomorrow.\\
'''Wakko:''' Why, Yakko? What are we going to do tomorrow?\\
'''Yakko:''' [[WesternAnimation/PinkyAndTheBrain The same thing we do every day, Wakko]]. Unfortunately, I have no idea what that is.\\
'''WesternAnimation/PinkyAndTheBrain''': They're zany, and they're the Warners, eight, eight, eight, eight, eight.

* ''Fanfic/TheWhiteWolfOfWesteros'' is a crossover between Series/GameOfThrones and Literature/TheWitcher. It begins at the end of VideoGame/TheWitcherIII with Ciri going to face the white frost, but something goes wrong, and upon going after her, Geralt is flung into the Game of Thrones just a few months before the main story would begin.

* ''WebAnimation/ZanyToTheMax'' has an episode where the Warners (it's an ''WesternAnimation/{{Animaniacs}}'' fan series) enter the world of ''Literature/TheTimeMachine'' and try to help the Time Traveler find Weena as part of a contest.

* One of the most prevalent type of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fan fics and fan works in general. The most regular kinds are those such as ''Fanfic/BetterLivingThroughScienceAndPonies'' (''VideoGame/{{Portal}}'') and ''WebAnimation/TurnaboutStorm'' (''VisualNovel/AceAttorney''), where another series' characters are transported to Equestria, sometimes [[FisherKingdom turning into ponies in the process]], and {{Fusion Fic}}s such as ''Fanfic/FalloutEquestria'' ([[VideoGame/{{Fallout}} guess]]) and ''Fanfic/FriendsOfASolarEmpire'' (''VideoGame/SinsOfASolarEmpire'').

* The longtime crossover champion for TV shows is ''The Witness'' by Michele Martin, which managed to cross ''Series/ForeverKnight'', ''Series/{{Highlander}}'', ''Series/TheXFiles'', ''Series/QuantumLeap'', and the ''Series/{{Starman}}'' TV series. Believe it or not, the fic manages to keep all those balls in the air successfully, and even bring in cameos from a few other series, all while following a coherent plot and keeping the characters in-character!

There is also [[https://1d4chan.org/wiki/Codex_-_The_Banished a codex for the Banished,]] the heretic Covenant from ''Halo Wars 2.''
* [[https://www.fanfiction.net/s/12381819/1/The-Connie-Ronnie-Switcheroo The Connie-Ronnie Switcheroo]] largely takes place in the ''WesternAnimation/TheLoudHouse'' universe, where two of the characters are observing an AlternateUniverse where one of those characters (Ronnie Anne Santiago) has swapped places with a character from ''WesternAnimation/StevenUniverse'' (Connie Maheswaran), resulting in the two characters befriending the opposite main characters (Lincoln Loud and Steven Universe) of those respective shows. This is achieved by using mutliversal transmitter goggles, which were apparently borrowed from [[Franchise/RickAndMorty Rick Sanchez]] of all people.
* The game-idea series [[http://crossoverx.wikia.com/wiki/Crossover_X_Wiki Crossover X]] practically ''lives'' on this trope. It even uses the word "crossover" in its name.

WordOfGod states that the series will cross over into multi-crossover territory in later parts. The second part [[spoiler: will establish pairings. Link is said to be paired with Sia, the titular princess of ''VideoGame/LadySia'' and Sora will be paired with Sheba from ''VideoGame/GoldenSun'']]. How that will work out remains to be seen...
** WordOfGod still hasn't mentioned ''how'' the characters will travel to the other worlds, but perhaps that'd get into spoiler territory.

Uncommonly for the genre, it is an amalgamation of the two universes (the characters from Bungo Stray Dogs follow the laws of the Madoka Magica universe) and the characters of the franchises don't meet eachother. The endnote implies that it is part of a larger crossover universe.
* ''[[http://www.fanfiction.net/s/7843635/1/Portalborn Portalborn]]'' is actually inspired by the ''VideoGame/Portal2'' Mod for ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''.

However, thanks to the interdimensional meddling of Elune's elf ChosenOne and Sargeras' new lieutenant (also an elf), plus the fact there are elves in both dimensions, now Magix and Azeroth have met. Or, rather, Bloom (now Eraklyon's queen) gets suddenly stripped out from the planet while investigating a rare disease (a new Undead Plague, workings of the Burning Legion elf) that has killed thousands of citizens. And she appears in Sin'dorei territory, gets to meet Sylvanas Windrunner and Elune's ChosenOne.

It's filled with tons of continuity nods and has everything, from ''WesternAnimation/TheWildThornberrys'', ''WesternAnimation/InvaderZim'', and ''WesternAnimation/DoraTheExplorer'' to ''WesternAnimation/{{Doug}}'', ''WesternAnimation/AaahhRealMonsters'', ''WesternAnimation/CatDog'', and ''WesternAnimation/MyLifeAsATeenageRobot''. Seriously; it is also [[RuleOfCool awesome]].
* 1d4Chan's [[https://1d4chan.org/wiki/Codex_-_The_Covenant Codex: the Covenant]] is a set of [[GameMod fan-made rules]] for fielding ''Franchise/{{Halo}}'s'' [[ScaryDogmaticAliens Covenant]] in ''TabletopGame/Warhammer40000'' battles. The HeroUnit lore involves Covenant heroes battling [=IoM=] SpaceMarines; for example, Cheif Tartarus threatening to eat Blood Ravens Chapter Master Gabriel Angelos. There is also [[https://1d4chan.org/wiki/Codex_-_The_Banished a codex for the Banished,]] the heretic Covenant from ''Halo Wars 2.''
* [[https://www.fanfiction.net/s/12381819/1/The-Connie-Ronnie-Switcheroo The Connie-Ronnie Switcheroo]] largely takes place in the ''WesternAnimation/TheLoudHouse'' universe, where two of the characters are observing an AlternateUniverse where one of those characters (Ronnie Anne Santiago) has swapped places with a character from ''WesternAnimation/StevenUniverse'' (Connie Maheswaran), resulting in the two characters befriending the opposite main characters (Lincoln Loud and Steven Universe) of those respective shows. This is achieved by using mutliversal transmitter goggles, which were apparently borrowed from [[Franchise/RickAndMorty Rick Sanchez]] of all people.

* The game-idea series [[http://crossoverx.wikia.com/wiki/Crossover_X_Wiki Crossover X]] practically ''lives'' on this trope. It even uses the word "crossover" in its name.

* ''[[http://www.fanfiction.net/s/10020026/1/Delivered-From-Frollo Delivered From Frollo]]'' crosses ''The Hunchback of Notre Dame'' with ''Fantasia''.
* ''VideoGame/DeltaTraveler'' is a crossover between ''VideoGame/{{Undertale}}'' and ''VideoGame/{{Deltarune}}'', where Kris and Susie wake up in the underground.

* [[http://www.fanfiction.net/s/5803383/1/Divine_Intervention Divine Intervention]] The [[Film/TheBoondockSaints MacManus brothers]] meet the [[Series/{{Supernatural}} Winchester brothers.]] And it is COOL.
* A favourite for many seems to be ''Series/DoctorWho'', due to the remarkable ease with which the Doctor can be inserted in any story just by having the TARDIS land there.
** The first well-known example 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.
** One of the most famous, ''Fanfic/TheManWithNoName, is a ''Series/{{Firefly}}'' / ''Doctor Who'' crossover, which some say should be officially added to {{Canon}}.
** Yet it VERY strangely lists one of the unofficial rules of the internet dealing with crossovers (specifically, [[Franchise/TouhouProject rule ⑨]]
** There's also ''Fanfic/AHero'', a crossover with ''Anime/PuellaMagiMadokaMagica'' which subverts most ''Series/DoctorWho'' crossover formulas by instead inserting [[ScaryDogmaticAliens Dalek]] [[MadScientist Sec]] to fix the mess.
** Another crossover that's become increasingly popular is Superwho, which combines ''Doctor Who'' with ''Series/{{Supernatural}}''.
*** Add one more show, ''Series/{{Sherlock}}'', to get Superwholock, which has become quite popular on Tumblr.
** All it took was one scene where a pony had a David Tennant-like hairstyle and an hourglass on his quarter. The result is that under crossovers at Website/FanFictionDotNet, ''Doctor Who'' is the most popular thing to cross into the world of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', beating out Franchise/SonicTheHedgehog.
** ''Fanfic/ChildrenOfTime'' crosses Ten's era with Literature/SherlockHolmes '''and''' ''WesternAnimation/SherlockHolmesInTheTwentySecondCentury''. Holmes and Watson take Martha Jones' place in Season 3 as Companions, with just a handful of episodes staying close to the original. The Eleventh Doctor is planned to make an appearance eventually...

* ''Literature/TheDresdenFiles'' has a lot of crossovers, including a rare crossover with ''Series/{{Buffy|The Vampire Slayer}} that ''doesn't'' involve its "Halloween" episode. [[https://www.fanfiction.net/s/6600971/1/Higher-Stakes-A-Fanfiction-of-the-Dresden-Files Higher Stakes: A Fanfiction of the Dresden Files]] is complete. It contains spoilers for ''Changes'' and the ''[[ComicBook/BuffyTheVampireSlayer Buffy Season 8]]'' comics, replaces everything after ''Changes,'' and after the ''Buffy'' comics arc "Time of Your Life".

* ''Webanimation/EverythingIsBroken'' is about ''Webanimation/HappyTreeFriends'' characters playing ''Westernanimation/MyLittlePonyFriendshipIsMagic'' {{creepypasta}} games that [[TheGamePlaysYou come to live and attack them]].
* [[http://www.fanfiction.net/u/1263379/gabriel_blessing Gabriel Blessing]] is well known for his two ''VisualNovel/FateStayNight'' crossovers:
** ''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/InFlight'', a ''Manga/{{Sekirei}}'' crossover where Shirou discovers his NotQuiteDead mother, Takami Sahashi, and replaces Minato as the Ashikabi of the North.

* [[https://archiveofourown.org/works/14487714 Game of Mass Destruction]] crosses over multiple fandoms and has The Joker as president.
* The ''Series/{{Glee}}'' fanfic ''Fanfic/HuntingTheUnicorn'' becomes a three-way crossover with ''Series/{{Firefly}}'' and ''Series/CriminalMinds''. [[spoiler: After Blaine and Kurt get rescued from Blaine's stalker,]] Blaine is taken to the Blue Sun hospital for his concussion, where Simon Tam treats him. He later calls the BAU when Blaine's distressed but incoherent rambling gives Simon the suspicion that [[spoiler: the stalker sexually assaulted Blaine.]]
* ''[[Fanfic/GodsAngelsAndKings 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}}
* Fanfic wise, it's almost impossible to find a fandom that ''doesn't'' have a crossover with ''Literature/HarryPotter''.
** There are crossovers of ''WesternAnimation/TheLandBeforeTime'' with ''Franchise/StarWars'', ''[[Literature/InheritanceCycle Eragon]]'', ''VideoGame/MegaMan,'' and, in one case, ''VideoGame/{{Halo}}.'' [[http://www.fanfiction.net/s/3007925/1/Star_Wars_The_Land_Before_Time_A_Jedis_Destiny Amazingly, many find that the Star Wars/Land Before time crossover in question is actually good.]]
*** [[http://www.fanfiction.net/s/4307557/1/Harry_Potter_and_the_Land_Before_Time Found the cross between Harry Potter and The Land Before Time!]]
*** "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.]]
** There is a really good one between ''Literature/HarryPotter'' and ''VideoGame/FinalFantasyVIII'' that starts when Harry, age 5, is magically transported to the world of [[VideoGame/FinalFantasyVIII FF8]] and once there he becomes a fine Gunblade fighter and is somehow able to use [[VideoGame/FinalFantasyVIII FF8]] magic and do everything one can in the game... without using Guardian Forces. He later has to go back to his own world, where an evil Dumbledore lays in waiting... See [[http://www.fanfiction.net/s/3471134/1/ here for the prequel+ Philosopher's Stone]] arc, [[http://www.fanfiction.net/s/3531911/1/ here for the Chamber of Secrets]] arc and [[http://www.fanfiction.net/s/3580477/1/ here for the Prisoner of Azkaban]] arc. It's a pity that the third arc is not finished...
** 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.]]
** Harry Potter in ''Film/ThePrincessBride''. Hermione dreams the people she knows into the plot of the movie, with herself in the role of the Grandson being read the book by Dumbledore. [[http://www.fanfiction.net/s/135041/1/Harry_Potter_and_the_Florinese_Dream No, really!]]
** One involved the plot of ''Pretty Little Liars'' being re-imagined in the Potter universe. Unlike most other crossovers, the characters of both series don't actually meet. [[http://www.fanfiction.net/s/6701410/1/Pretty_Little_Witches Here it is]]
** Since both Harry and Edward Elric are looking for the PhilosophersStone at some point, there's a lot of crossover fanfiction with ''Manga/FullmetalAlchemist''.
** ''Snakeskins'' is, without a doubt, one of the best fanfics in the whole crossover with ''Webcomic/HetaliaAxisPowers'' fandom, in which the two universes are blended amazingly and England and Italy are still their immortal Nation-tan selves while they're at Hogwarts. It... sounds kinda confusing, but it's a lot simpler in context.
** ''Fanfic/HarryPotterBecomesACommunist'' does some crossovers with other ''Harry Potter'' fanfics. This consists of, to date, brief appearances by the Professor Quirrell from ''Fanfic/HarryPotterAndTheMethodsOfRationality'', Ebony Dark'ness Dementia Raven Way from ''FanFic/MyImmortal'', and Rhysenn Malfoy from ''Fanfic/TheDracoTrilogy''.
* Franchise/{{Highlander}}. You can dump Duncan or Connor or any of the other Immortals in almost any historical period; or assume, for a series set today that this or that character is Immortal; or for series set in the future, assume that someone from a 20th/21st C. series was a Highlander and hadn't lost his/her head before then. Of all the methods that ''Series/LawAndOrderUK'' fanfic writers used to revive the murdered DS Matt Devlin, revealing that he was an Immortal--as well as technically crossing over with ''another'' [[Series/HoratioHornblower series]] in the story ''[[https://fanfiction.net/s/7622098/1/Declassified Declassified]]'' by revealing that he was also Archie Kennedy--might have been the most creative.
* In the ''Fanfic/SkyholdAcademyYearbook'' series, ''I Must Be Going'' manages to be both this trope ''and'' SelfInsertFic. It's a crossover from the reader's point of view, being a merging of ''VideoGame/DragonAgeInquisition'' and ''Film/ThePrincessBride''. However, it's a StoryWithinAStory, written and narrated by Varric Tethras; and to the people listening to him read it, it's a SelfInsertFic because ''they're'' the ones in it.

* ''Fanfic/InvaderFranny'' was an unfinished crossover between Nickelodeon cartoon ''WesternAnimation/InvaderZim'' and the children's book series ''Literature/FrannyKStein'' where Franny starts attending the Skool, befriends Dib and ends up time-traveling to a BadFuture where she and Dib have to help Franny's future self take down an evil future version of Dib named Dark.
* ''Fanfic/JauneArcLordOfHunger'' is a crossover between ''WebAnimation/{{RWBY}}'' and ''Franchise/StarWars'', specifically the ''Franchise/StarWarsLegends'' continuity. The fic's premise sees Jaune get possessed by the Force ghost of [[VideoGame/KnightsOfTheOldRepublic Darth Nihilus]] right before he enrolls into Beacon Academy.

*** The sequel to the What-Ifs (this one involving Kazuya and the Rune Angels while continuing to honor the original's variances in terms of who Arnold and Tact are in relationships with in each parallel universe) sees Amethyst herself appear (suggested by Khaos himself for the chapter that would become Natsume's route for Kazuya as a way to avoid the CrossDresser episode). Amethyst was identified as a Khaos character by the other author whose lead OC prominently appeared in Khaos' christmas special (and one of his works, along with the Natsume-eventually route of the What-Ifs, are mentioned specifically as how Arnold Williams (the lead OC of the author behind Khaos creating Jace Davies and Marty Jordan) and William Johnson (the lead OC of the author who identified Amethyst as Khaos') made it to the Christmas party).
*** Three works by former author "Witchan" featured Khaos' characters (Jet and Amethyst, plus Taylor 'Thundrana' Johnson and Georgia Millar, appear in a Mario Kart story that Khaos still references often (usually in tandem with Khaos' own sequel); Jet and Amethyst, alongside Rochelle, appear in the inspiration of a story series since fused with another author's own similarly-themed Pokemon stories (three in particular follow eventual Rainbow Angels Rosa Copeland, Roxanne Mazaki, and Jasmine Levesque as prostitutes though Jasmine goes out of her way to hide her being one); and Rochelle herself appears in a third where a tech malfunction by overloading leads to Rochelle creating an upgraded variant of the tech in question).

* Two ''Series/LawAndOrderUK'' fanfics:
** One that crosses over with ''Series/{{Highlander}}'' and ''Series/HoratioHornblower'' has Matt Devlin recovering from the bullet wounds he sustained and explaining to a stunned Alesha and Ronnie that he's immortal and is really Archie Kennedy of the latter series (also probably lampshading [[Creator/JamieBamber Jamie Bamber's]] ChronicallyKilledActor status).
** Another sent Matt and Ronnie to Washington, DC to work with the ''Series/{{NCIS}}'' team. Rather [[HilariousInHindsight amusing]] considering that a) Creator/JamieBamber eventually began a recurring role on the show, and b) thehe team actually did work with UsefulNotes/BritishCoppers at one point.
* ''Fanfic/LegacySekiroKimetsuNoYaiba'' has Sekiro living hundreds of years into the time of Demon Slayer, where demons now roam the land due to Kibitsuji Muzan. Taking in an orphaned boy named Kiyoshi, Wolf decides to help the boy channel his thirst for {{revenge}} into becoming a legendary demon slayer and his successor as the One-Eyed Fox.
* ''Fanfic/LightAndDarkDEUXTheNewAdventuresOfDarkSoichiro'' is a FanSequel to ''Fanfic/LightAndDarkTheAdventuresOfDarkYagami'', which crosses over with other {{Troll Fic}}s, with the description advertising the presence of [[Fanfic/CodeGeassAwesomeOfTheRebellion Awesome de Britannia]], and [[Fanfic/MyImmortal Enoby]].
* ''Fanfic/TheLoneTraveler'': The eponymous Traveler, Harry Potter from a [[Fanfic/HarryPotterAndTheNightmaresOfFuturesPast Nightmares of Futures Past]]-type universe, moves through the multiverse, ''Series/QuantumLeap'' style.
* 4 crossovers with ''WesternAnimation/LooneyTunes'' and ''WesternAnimation/WinxClub'' have been done by [[http://www.fanfiction.net/~looneywriter looneywriter]] and [[http://www.fanfiction.net/~kidswbyungsta kidswbyungsta]]. Sure enough, keeping in with the Looney Tunes style of humor, as well as adding characters from ''WesternAnimation/{{Animaniacs}}'', ''WesternAnimation/TinyToonAdventures'', and ''WesternAnimation/PinkyAndTheBrain'' may have helped them grow to be loved by many on Website/FanFictionDotNet.
* One of the most prevalent type of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fan fics and fan works in general. The most regular kinds are those such as ''Fanfic/BetterLivingThroughScienceAndPonies'' (''VideoGame/{{Portal}}'') and ''WebAnimation/TurnaboutStorm'' (''VisualNovel/AceAttorney''), where another series' characters are transported to Equestria, sometimes [[FisherKingdom turning into ponies in the process]], and {{Fusion Fic}}s such as ''Fanfic/FalloutEquestria'' ([[VideoGame/{{Fallout}} guess]]) and ''Fanfic/FriendsOfASolarEmpire'' (''VideoGame/SinsOfASolarEmpire'').
** Another example is ''Fanfic/TheLittlePonyLegend'', crossing over ''Friendship is Magic'' with ''WesternAnimation/TheLegendOfKorra''. It's also something of a self-insert fic, as the ponies are "inserted" into Korra's plot and vice versa over the course of the seven fics present.
* 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.
* There's a fanfic series by [[https://www.fanfiction.net/u/4205892/GamesMaster64 GamesMaster64]] called "The Legend of Hyrule Hearts" (shortened to [="LoHH"=] by the author), which crosses over ''Franchise/TheLegendOfZelda'' and ''Franchise/KingdomHearts'' ... for the first story anyway... WordOfGod states that the series will cross over into multi-crossover territory in later parts. The second part [[spoiler: will establish pairings. Link is said to be paired with Sia, the titular princess of ''VideoGame/LadySia'' and Sora will be paired with Sheba from ''VideoGame/GoldenSun'']]. How that will work out remains to be seen...
** WordOfGod still hasn't mentioned ''how'' the characters will travel to the other worlds, but perhaps that'd get into spoiler territory.
*** WordOfGod states there's also 20 parts planned, with about five specials. This guy's in it for the long haul. The series appears to be dead, but the author blames it on writer's block and real-life being busy.
* It's easier to count the things that Naruto hasn't had crossovers with when it's had crossovers with ''ComicStrip/TheBoondocks'', ''VideoGame/DukeNukem'', ''WesternAnimation/AquaTeenHungerForce'', ''Film/MeanGirls'', ''Godzilla'', ''Franchise/FridayThe13th'' and probably the strangest with ''Series/MarriedWithChildren''.
* ''Fanfic/TheManyWorldsInterpretation'' brings together dysfunctional academics from two fictional universities: the core crew from ''Series/TheBigBangTheory'' interact with the Faculty of [[Literature/{{Discworld}} Unseen University]]. As Ponder Stibbons has a meeting of minds with Leonard Hofstadter, aided and hindered by Sheldon, Howard and Raj, women from two worlds have to act as a collective TeamMom for them.
* ''Fanfic/TheMountainAndTheWolf'': ''Series/GameOfThrones'' meets ''TabletopGame/WarhammerFantasy''. More specifically, the Mountain's duel with Oberyn Martell happens against someone very different, very large, and very keen about certain bloodthirsty gods...
* ''Fanfic/{{Myrmridon}}'' by Ser Serendipity has Team 8 from ''Manga/{{Naruto}}'' take on a mission in ''Manga/HunterXHunter''[=’s=] NGL.
* [[http://www.fanfiction.net/s/7897742/1/Platinum-Angel This fic]], a crossover of ''Manga/{{Chobits}}'' with, of all things, ''Franchise/AssassinsCreed'' (trope page [[Fanfic/PlatinumAngel here]]). Word from the author is that the eventual sequel will add ''Manga/MidoriDays'' to the mix as well.
* ''[[Fanfic/TheLongRoad2015 The Long Road]]'' is an AlternateTimeline crossover story of the ''WesternAnimation/RiseOfTheGuardians'' and ''WesternAnimation/HowToTrainYourDragon'' canons, not to be confused with a ''Dragon Ball Z'' fanfic [[Fanfic/TheLongRoad of the same name]].
* ''Fanfic/ObjectShowsUnite'' 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.
* ''Fanfic/OfLovebugsAndPromises'' is an Avengers KidFic set in the ''Series/WhiteCollar'' universe with Phil Coulson being an agent of (a different state's branch of) the FBI's White Collar Unit.
* This is basically the whole point of ''Fanfic/TheOmniverseEvent''. Currently, the fandoms include ''ComicStrip/CalvinAndHobbes'', ''Franchise/BerniceSummerfield'', ''Franchise/YuGiOh'', and ''Series/StarTrekVoyager'', with the promise of a lot more on the way.
* ''[[https://archiveofourown.org/works/16749352/chapters/39293203 Only Void Remains]]'' is a crossover of ''Manga/BungoStrayDogs'' and ''Anime/PuellaMagiMadokaMagica'' and follows the plot of the Light Novel ''Dazai Osamu and the Dark Era'' roughly. Uncommonly for the genre, it is an amalgamation of the two universes (the characters from Bungo Stray Dogs follow the laws of the Madoka Magica universe) and the characters of the franchises don't meet eachother. The endnote implies that it is part of a larger crossover universe.
* Fanfic/{{Paradoxus}} crosses over VideoGame/WorldOfWarcraft and WesternAnimation/WinxClub. Azeroth and Magix are both dimensions created by the First Ones, just so far away from each other it ''normally'' wouldn't have been a chance to clash. However, thanks to the interdimensional meddling of Elune's elf ChosenOne and Sargeras' new lieutenant (also an elf), plus the fact there are elves in both dimensions, now Magix and Azeroth have met. Or, rather, Bloom (now Eraklyon's queen) gets suddenly stripped out from the planet while investigating a rare disease (a new Undead Plague, workings of the Burning Legion elf) that has killed thousands of citizens. And she appears in Sin'dorei territory, gets to meet Sylvanas Windrunner and Elune's ChosenOne. Some time afterward, Bloom and Stella are assassinated by the now multi-dimensional menace ([[BreakTheCutie in front of the former's kid daughter]]) and it's up to [[FanCreatedOffspring their daughters]] to try and fix the situation.
* 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.
* ''Fanfic/PokemonCrossingFlyMeToTheMoon'': VideoGame/AnimalCrossing villagers live in the Franchise/{{Pokemon}} world; some become trainers, gym leaders, or villainous teams.
* ''[[http://www.fanfiction.net/s/7843635/1/Portalborn Portalborn]]'' is actually inspired by the ''VideoGame/Portal2'' Mod for ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''. In starts off using the original elements of Fall of the Space Core after pitting [[{{Tsundere}} The]] [[BloodKnight Dragonborn]] with the weird and cooky [[CrazySurvivalist Doug Rattmann]]. It gets crazy, then evolves with a mysterious and adventurous plot.
* ''Fanfic/QuinnInWonderland:'' [[Series/{{Glee}} Quinn Fabray]] falls DownTheRabbitHole and ends up in [[Literature/AliceInWonderland Wonderland]]
* The ''Manga/RanmaOneHalf'' fandom loves to create crossovers. There exists several archives devoted to them. Particularly common are crossovers with ''Franchise/SailorMoon'' which has a sub genre called the FukuFic that has more fan fics written for it than most anime has fan fics total.
* Raquaza Master's [[http://s1.zetaboards.com/PokeTown_2/index/ Pokemon Squad]] fanfics are supposed to combine the characters from Franchise/{{Pokemon}}, ''WesternAnimation/KaBlam!'', ''Series/BarneyAndFriends'' (Barney is going to be one of the main antagonists), ''WesternAnimation/DannyPhantom'', ''WesternAnimation/{{Animaniacs}}'', ''Series/SesameStreet'' (Elmo's going to be an upcoming villain), many video games, and much, much more.
* The fancomic ''Webcomic/{{Roommates}}'' by [[http://asherhyder.deviantart.com/ Ashe Rhyder]] and its spinoff ''Webcomic/GirlsNextDoor'' by [[http://pika-la-cynique.deviantart.com/ Pika la Cynique]] are this -- a crossover between ''Film/{{Labyrinth}}'', ''Theatre/ThePhantomOfTheOpera'', ''Franchise/PiratesOfTheCaribbean'', ''Literature/LesMiserables'', and occasionally ''Literature/HarryPotter'' -- the many fandoms that appeared only once or twice are too numerous to count. Both by now run rather independently of each other, with a frequent ContinuityNod and ShoutOut to each other during their many, many storylines. And they are also awesome.
* If you [[AlternateUniverseFic relocate]] ''WesternAnimation/ChipNDaleRescueRangers'' from TheEighties to TheSeventies, you can cross it over with ''Series/{{Kojak}}''. ''Fanfic/TheRodSquad'' does so briefly.
* Creator/RoseOfPollux writes these occasionally.
* The ''Fanfic/RoyalHeights'' combines three animated shows and places them into a sci-fi/fantasy school setting. But not in the way one would expect.
* [[RulesOfTheInternet Rule ⑨]]: If it exists, there is a crossover with ''Franchise/TouhouProject''. [[FanficRecs/TouhouCrossover The series even has its own article.]]
* Due to their popularity, it's very easy to find on [=deviantArt=] crossovers involving ''LetsPlay/TheRunawayGuys'', mostly by [=ThatOneNPC=]. The guys have crossed over with such works as ''Film/TheWizardOfOz'', ''Literature/AliceInWonderland'', ''VideoGame/Portal2'', ''VideoGame/{{Slender}}'', ''VideoGame/ProfessorLaytonVSAceAttorney'' and ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' ([[http://fav.me/d4vqwcn no really]]), to name a few.
** Each of the guys themselves has been subject to individual crossover fanart. For instance, [[http://fav.me/d4wius7 here]] is fanart crossing over LetsPlay/{{Chuggaaconroy}} with VideoGame/ProfessorLayton. (Chugga liked it, by the way.)
* ''Fanfic/SayItThrice'' is a blending of ''WesternAnimation/DannyPhantom'' and the film ''Film/{{Beetlejuice}}.'' Two years post-movie, Lydia is forced by circumstance to move to Amity Park to live with her mother's sister, and befriends Danny, Sam, and Tucker.
* [[http://www.fanfiction.net/community/Seanzilla115-s-Multi-crossover-stadium/86737/3/0/1/ Seanzilla115's Multi crossover stadium]], This Fanfiction community contains some of the greatest crossover stories by the greatist authors Fanfiction.Net has to offer.
* ''Fanfic/ShinjiAndWarhammer40K'' is sort of an odd example. It is not a story where the universes meet, being more of a ForWantOfANail story about Shinji getting a large amount of TabletopGame/Warhammer40000 pieces and rulebooks as a child. His different (happier) childhood makes for a more dynamic protagonist and leads him to influence the rest of the cast into making things that fit the 40K ethos more than the original Evangelion series did. It's not the straightest example of a universe to universe CrossOver.
* ''Fanfic/SOE2LoneHeirOfKrypton'': Between Franchise/{{Superman}} and ''Anime/NeonGenesisEvangelion''. Asuka knew she had been conceived by sperm donor. What she did not knew was her biological father was an alien from another planet, and his DNA confered vast powers on her. Shortly after finding out about it, she becomes ''ComicBook/PowerGirl'' and later ''ComicBook/{{Supergirl}}''.
* ''Fanfic/ThousandShinji'': Between ''Anime/NeonGenesisEvangelion'' and ''TabletopGame/Warhammer40000''. A Sorcerer of Thousand Sons Legion fumbles a spell and travels back in time, finding a young Shinji Ikari and raising him.
* ''Fanfic/TheVampireOfSteel'' is a cross between ''Series/BuffyTheVampireSlayer'' and ''ComicBook/{{Supergirl}}'', set in a [[Franchise/TheDCU DC Universe]] where Sunnydale exists.
* Is there anyone Franchise/SonicTheHedgehog hasn't met yet? The blue hedgehog has had crossovers with [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_Percy_Jackson_and_the_Olympians_Crossovers/253/2622/ Percy Jackson]], [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_Godzilla_Crossovers/253/448/ Godzilla]], [[http://www.fanfiction.net/Transformers_Beast_Wars_and_Sonic_the_Hedgehog_Crossovers/65/253/ Transformers]], [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_Halo_Crossovers/253/1342/ Halo]], [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_iCarly_Crossovers/253/2898/ iCarly]], [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_Gorillaz_Crossovers/253/2340/ Gorillaz]], [[http://www.fanfiction.net/Mighty_Ducks_and_Sonic_the_Hedgehog_Crossovers/243/253/ the Mighty Ducks]], [[FanFic/FuckTheJesusBeam Tengen Toppa Gurren Lagann]], [[https://www.fanfiction.net/Sonic-the-Hedgehog-and-Strawberry-Shortcake-series-Crossovers/253/4511/ Strawberry Shortcake]] and [[https://www.fanfiction.net/Sonic-the-Hedgehog-and-Tinkerbell-Crossovers/253/3713/ Tinkerbell]]. Are any of these even remotely connected?
** But [[http://www.fanfiction.net/Sonic_the_Hedgehog_and_Mario_Crossovers/253/347/ we all know who the big winner is...]]
** [[http://www.fanfiction.net/s/7891955/1/Sonic-Generations-Friendship-is-Timeless This]] fanfiction crosses over ''Franchise/SonicTheHedgehog'' with the cast of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', in a reimagining of the plot of ''VideoGame/SonicGenerations''. It goes far beyond what the original game gives, showing the author did their research. For instance, Ponyville serves as the central [[NoPunIntended hub]], similar to the White Void in the game, the Death Egg Robot battle in the original is replaced with Nightmare Moon and in this fanfiction, Tails fights Metal Sonic instead of Sonic, possibly a reference to ''VideoGame/SonicTheHedgehog4''. The author has even adapted the updated canon of Friendship is Magic into the fanfic. However, how the author intends to implement alicorn Twilight is currently unknown.
** ''VideoGame/SonicManiaAndHatsuneMiku'': A ''very'' well-done GameMod of ''VideoGame/SonicMania'' that replaces the titular character with [[Music/{{Vocaloid}} Hatsune Miku]] wearing a Sonic parka, amongst a few other things.
* It's crazy just how many crossovers on Website/FanFictionDotNet exist between ''Franchise/SonicTheHedgehog'' and ''Franchise/SuperMarioBros''. Sure, [[VideoGame/MarioAndSonicAtTheOlympicGames this may have become canon]] but authors were doing it way before then.
* Franchise/SpiderMan has a slew of crossovers on Website/FanFictionDotNet. [[http://www.fanfiction.net/s/5011834/1/Web_of_Shadow_Fallout This one]] crossed with the Franchise/TeenageMutantNinjaTurtles, and [[http://www.fanfiction.net/s/3914495/1/A_Hospital_In_Jersey this one]] crossed with ''Series/{{House}}'' are quite good.
* ''Fanfic/StarsAbove'': A crossover between ''Franchise/MadokaMagica'' and ''Manga/LuckyStar'', in which the magical beings and darkness of the former invade the normal, everyday schoolgirl life of the latter... and it blossoms into an unlikely YuriGenre romance.
** ''Fanfic/{{Respect}}'', by one of the authors of ''Stars Above'', crosses ''Madoka'' with ''Anime/SmilePrettyCure''. It explores a WhatIf scenario in which [[TheCutie Yayoi]] becomes a Puella Magi instead of a Precure.
** ''Fanfic/ShatteredSkiesTheMorningLights'': Also by the same author, 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.
* ''Franchise/StarWars'' and ''Franchise/StarTrek''. The rivalry between their fanbases and The UltimateShowdownOfUltimateDestiny makes it a bygone conclusion feature some, and for those to require at least one major battle between the United Federation of Planets and the Galactic Empire, but there are certain exceptions.
** Another good one is [[http://sfdebris.com/unity.asp Unity]] by notable contributor Website/SFDebris. What is a wormhole was connected from the Delta Quadrant circa Voyager's fifth season to the Star Wars Universe circa early Return of The Jedi, (disrupting the Rebel Alliance's attempt to attack the second Death Star.) Involved every character from TNG forward moving well into the future and exploring all the potential interactions in detail.
** To complete the trifecta of renowned ''Star Wars'' vs. ''Star Trek'' fanfics, there's [[http://bbs.stardestroyer.net/viewtopic.php?t=404&highlight= StarCrossed]].

* ''Fanfic/{{Survivability}}'': The ''Manga/{{Bleach}}'' universe with an original plot, starring characters from different KPop groups (Music/DongBangShinKi, Music/SHINee, Big Bang, Music/SuperJunior, Music/B2ST, +other solo singers and actors).
* ''[[http://www.fanfiction.net/s/6095074/1/Takamachi_Nanoha_of_2814 Takamachi Nanoha of 2814]]'' is a ''Anime/MagicalGirlLyricalNanoha'' Crossover with ''ComicBook/GreenLantern''. Then, it started to cross over with ''everything'' by chapter 3. Written by the almost infamous Shadow Crystal Mage, so you know it's good. [[Fanfic/TakamachiNanohaOf2814 Now with its own page.]]
* ''Fanfic/TangledAdventuresInArendelle'': Going on their honeymoon, the main cast of ''Franchise/{{Tangled}}'' goes to visit [[WesternAnimation/Frozen2013 Arendelle]] for a month..[[OhCrap just at Queen Elsa's coronation]].

* ''[[Fanfic/TokimekiPokeLiveAndTwinbee Tokimeki PokéLive! and Twinbee]]'' is a lighthearted Seinen style crossover between ''Franchise/{{Pokemon}}'', ''Franchise/LoveLive'', ''VisualNovel/TokimekiMemorial'' and ''VideoGame/TwinBee'' that focuses on female characters from the ''Pokémon'' games, ''VideoGame/LoveLiveSchoolIdolFestival'', ''Love Live! Perfect Dream Project'', ''Tokimeki Memorial:Forever with You'' and ''Twinbee'' with female characters from other franchises making cameo appearances in various main stories. And there's also a Shonen style (Although still pretty lighthearted) spin off called ''Tokimeki PokéLive! and Twinbee Side Stories'' that have male Pokémon characters making appearances depending on the story arc and in addition, focuses more on characters who don't appear in the main stories at all or who don't appear that often in the main stories.
* At least 300 crossovers of ''WesternAnimation/TotalDrama'' are available on fanfiction.net

* When ''Fanfic/WithStringsAttached'' was first conceived, it was supposed to be a [[Music/TheBeatles Beatles]]/''TabletopGame/DungeonsAndDragons'' crossover. Luckily, the author quickly matured out of that notion, and the story turned into something far more interesting and complex, though its {{RPG}} roots are quite evident still.
* The longtime crossover champion for TV shows is ''The Witness'' by Michele Martin, which managed to cross ''Series/ForeverKnight'', ''Series/{{Highlander}}'', ''Series/TheXFiles'', ''Series/QuantumLeap'', and the ''Series/{{Starman}}'' TV series. Believe it or not, the fic manages to keep all those balls in the air successfully, and even bring in cameos from a few other series, all while following a coherent plot and keeping the characters in-character!

If they win, they will be able to [[ImTakingHerHomeWithMe take Weena home with them]]. [[spoiler: They don't win. WebAnimation/{{Homest|arRunner}}ripe [[AuthorAvatar Runner]] does instead.]] The episode is implied to turn into a MassiveMultiplayerCrossover by the end.

* Fanfic/{{Paradoxus}} is a cross overs VideoGame/WorldOfWarcraft and WesternAnimation/WinxClub. Azeroth and Magix are both dimensions created by the First Ones, just so far away from each other it ''normally'' wouldn't have been a chance to clash. However, thanks to the interdimensional meddling of Elune's elf ChosenOne and Sargeras' new lieutenant (also an elf), plus the fact there are elves in both dimensions, now Magix and Azeroth have met. Or, rather, Bloom (now Eraklyon's queen) gets suddenly stripped out from the planet while investigating a rare disease (a new Undead Plague, workings of the Burning Legion elf) that has killed thousands of citizens.
