* ''Fanfic/{{Paradoxus}}'': The Setting Merge flavor, to be specific. [[VideoGame/WorldOfWarcraft Azeroth]] and [[WesternAnimation/WinxClub Magix]] now happen to exist in the same multi-dimensional universe. It's just they are too far apart that, ''normally'', they would've never interacted at all. Here we have Galadwen and Eudora's constant interdimensional traveling and meddling ''and'' [[spoiler: Daphne]]'s time travel shenanigans, so things are definitely not normal (more like deranged). Now, there are already some canon points that keep this idea within the realm of possibility: there are elves in both franchises, [[ObviousCrossoverMethod interdimensional traveling is confirmed and used]] in both of them, and both of them have entities capable of creating entire dimensions (the First Ones for ''World of Warcraft'' and the Great Dragon for ''Winx Club''). Though it's worth noting the Great Dragon is not equal to the First Ones, but to the Titans (like Sargeras), which helps to even out the power scales and avoid a PowerCreepPowerSeep scenario and allows for the [[TeamUpSeries teaming-up plot]] this crossover roots from.

* ''[[https://www.fanfiction.net/s/10714818/1/Fallout-SG-1 Fallout: SG-1]]'' is a blending of ''VideoGame/{{Fallout}}'' and ''[[Franchise/StargateVerse Stargate]]''; In this universe, ''SG-1'' is composed of an old Daniel Jackson who lived most of his life on Abydos, [[Characters/FalloutNewVegasCompanions Veronica Santangelo, Arcade Gannon]], and of course [[TokenNonHuman Teal'c]]. Carter was an astronaut for the [[AlternateHistory USSA]], which fits what regularly occurs to her during the show's regular visits to [[AlternateUniverse alternate realities.]]

* ''Fanfic/SchoolIdolDays'' uses the characters of ''Anime/LoveLive'' with the plot of ''VisualNovel/SchoolDays''. [[DarkFic It's about as jarringly brutal as it sounds.]] Its sequel, ''School Idol Days S'', averts this, as it is based on ''Anime/LoveLiveSunshine'' but has an original story.

* Many works by Lightyearpig have done this. The ''Fanfic/MarvelGemsUniverse'' inserts characters from the Franchise/MarvelUniverse into ''WesternAnimation/StevenUniverse'', ''Fanfic/FoolyFalls'' and ''Fanfic/GravitySoul'' feature [[WesternAnimation/GravityFalls Dipper and Mabel Pines]] interacting with characters from ''Anime/{{FLCL}}'' and ''Manga/SoulEater'', ''Sly Cooper: Boiling Blood'' transports VideoGame/SlyCooper into the Boiling Isles from ''WesternAnimation/TheOwlHouse'', and ''Fanfic/ShelluvaBoss'' has the Immediate Murder Professionals from ''WebAnimation/HelluvaBoss'' being hired to kill the Franchise/TeenageMutantNinjaTurtles.

* ''[[https://archiveofourown.org/works/16803172/chapters/39439951 Battle Spirit]]'' features [[Manga/BattleTendency Joseph Joestar]] as [[WesternAnimation/AvatarTheLastAirbender the Avatar]] training to defeat a trio of dark spirits.

* ''Fanfic/ADifferentKindOfTruth'' has Johnny Joestar from Part 7 of ''Manga/JoJosBizarreAdventure'' replace the SilentProtagonist of ''VideoGame/Persona4'', disability and bitterness included. It also makes Personas closer to Stands.

* ''FanFic/VanishingAct'' ties together the worlds of ''Franchise/{{Persona}}'' and ''Manga/JojosBizarreAdventure''. This leads to such developments as [[VideoGame/Persona3 Aigis]] being based off the technology used to create [[Manga/BattleTendency Stroheim's cyborg body]], [[VideoGame/Persona5 Hifumi Togo]] [[spoiler:being a Stand user whose ability makes her a natural shogi champion]], and the main thrust of the fic, [[Manga/DiamondIsUnbreakable Shizuka Joestar]] becoming a PhantomThief.

* In ''Fanfic/RachelTheVampireSlayer'', the settings of ''Literature/{{Animorphs}}'' and ''''Series/BuffyTheVampireSlayer'' are merged.

* ''VideoGame/HoloFunk'' is a ''VideoGame/FridayNightFunkin'' overhaul mod featuring the cast of ''WebAnimation/{{hololive}}'' in an AlternateUniverse with the tone of ''FNF''. It also features multiple characters from several other sources [[note]]''VideoGame/{{Yakuza}}'', ''VideoGame/{{Pico}}'', and several other [[VirtualYoutuber VTubers]].[[/note]] and the original ''Friday Night Funkin''' cast rewritten into the context of the ''[=HoloFunk=]'' universe, with most being featured [[Fanfic/TheDragonsPizzeria in the backstory]].

** ''[[https://www.deviantart.com/rvbomally/art/In-At-The-Undeath-356611550 In At The Undeath]]'' is a fusion of ''Literature/Timeline191'' and the author's own timeline ''Literature/VivereMilitareEst'', with the [[ANaziByAnyOtherName Freedom Party regime]] using preternatural forces in an attempt to win the Second Great War much like the Axis in ''Militare Est''.

* Various AlternateHistory works by ''Creator/Rvbomally'':

* ''Fanfic/TheFirstSaniwa'', a ''VideoGame/ToukenRanbu''/''VideoGame/{{Onmyoji}}'' crossover that merges aspects of both games' canons and uses one game's canon to explain the other's. For example, Yorimitsu is the ancestor of the present day saniwa, [[spoiler:the canonical fact that Onigiri isn't actually the personification of the sword he represents allows him and Higekiri to exist in the same universe]], and [[spoiler:Kuro Seimei]] is actually the work of Historical Revisionists.
