History CrossOver / Fanworks

{{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.

* ''Fanfic/MegamiNoHanabira'' is a crossover between the unrelentingly dark ''Franchise/ShinMegamiTensei'' and the SugarWiki/{{WAFF}}-y GirlsLove {{Eroge}} ''Sono Hanabira Ni Kuchizuke Wo''.

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

* ''Fanfic/DemonOfJustice'' is older than Website/FanFictionDotNet and crosses ''Anime/MobileSuitGundamWing'' with ''[[Literature/TheWarGods Oath of Swords]]'', a high fantasy series.

* ''Fanfic/IfWishesWerePonies'' is a crossover between ''Franchise/HarryPotter'' and ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Harry arrives in Equestria before recieving his Hogwarts letter. Shenanigan ensue. There are dozens of stories under the Harry Potter tag on Website/FimfictionDotNet.

* ''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 that 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. A little while after, 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.

''The Legend of Hyrule Hearts'' crosses over ''Franchise/TheLegendOfZelda'' and ''Franchise/KingdomHearts'', with later stories also involving ''VideoGame/LadySia'' and ''VideoGame/GoldenSun''.

* ''Fanfic/BondBreaker'' has a SelfInsert of the author get pulled around the multiverse by a race of godlike beings wanting to find the answer to the "is there a God?" question. He gets to visit Manga/{{Naruto}}, [[Anime/NeonGenesisEvangelion NGE]], VideoGame/MassEffect, Literature/HarryPotter, Franchise/TheLegendOfZelda, WesternAnimation/{{Frozen|2013}}, Anime/SwordArtOnline, Franchise/StarWars, ''TabletopGame/Warhammer40000'', VisualNovel/FateStayNight and [[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]], to name a few.

* In ''Fanfic/AmazingFantasy'', Izuku turns down [[PointOfDivergence turns down an alleyway]] instead of walking under a bridge and gets bitten by a genetically-altered (and possibly radioactive) spider, giving him the powers of ComicBook/SpiderMan. A few weeks later, a [[OlderAndWiser 47-year-old]] Peter Parker drops into Izuku's universe after a brawl with Mysterio.

* ''Fanfic/InfinityTrainBlossomingTrail'' is an ''WesternAnimation/InfinityTrain'' crossover with ''Anime/PokemonTheSeries'' where Chloe Cerise decides to find herself and grow not by going through a Pokémon journey, but by visiting the infinite dimensions in the Infinity Train itself.

* In ''Fanfic/AmazingFantasy'', Izuku turns down [[ForWantOfANail turns down an alleyway]] instead of walking under a bridge and gets bitten by a genetically-altered (and possibly radioactive) spider, giving him the powers of ComicBook/SpiderMan. A few weeks later, a [[OlderAndWiser 47-year-old]] Peter Parker drops into Izuku's universe after a brawl with Mysterio.

* ''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.
