History MassiveMultiplayerCrossover / VideoGames

** With ''[[VideoGame/SuperSmashBrosBrawl Brawl]]'' (the third iteration), the series took it a step further by adding third-party {{Guest Fighter}}s to the mix, with Creator/{{Konami}}'s Solid Snake from the ''Franchise/MetalGear'' series and Creator/{{Sega}}'s VideoGame/SonicTheHedgehog joining the fight.[[note]]''Sonic'' was actually intended to be in ''Melee'', but by the time Creator/MasahiroSakurai could ask Sega, the game was too far along its (already brutal) development. Similarly, Creator/HideoKojima wanted Snake in ''Melee'', but he requested too late in the game's development.[[/note]]

Bison]], [[VideoGame/FinalFight Haggar]], [[VideoGame/FatalFury Andy Bogard, Lawrence Blood, Mai Shiranui]], [[Franchise/SuperMarioBros Mario, King Koopa]], VideoGame/SonicTheHedgehog, [[Franchise/TeenageMutantNinjaTurtles Leonardo]], and [[Franchise/DragonBall Goku]].

** This isn't limited to the characters either, a plugin allows you to have the campaign of an idtech 1 compatible .iwad to generate with enemies from all across these games, That spot where you find, say, a [[VideoGame/{{Doom}} Baron of Hell]] might instead have a [[VideoGame/{{Marathon}} Juggernaut]], a [[VideoGame/DarkForces Phase II Dark Trooper]], or an [[VideoGame/HalfLife1 M1 Bradley]].

* In Japan, ''VideoGame/TheUnholyWar'' was given a makeover as "Little Witching Mischiefs" and featured seven of the first magical girls to exist from ''Anime/SallyTheWitch'', ''Anime/HimitsuNoAkkoChan'', ''Anime/HanaNoKoLunlun'', ''Anime/MahouTsukaiChappy'', ''Anime/MahouShojoLalabel'', ''Anime/MajokkoMegChan'', and ''Anime/CuteyHoney''.

There's no relation between those two titles [[spoiler: except for the same villain, named Zetsumu]].

* Creator/BandaiNamcoEntertainment's ''Nendoroid Generation'' is an obscure UsefulNotes/PlayStationPortable crossover RPG where you can see characters from ''Literature/HaruhiSuzumiya'', ''Anime/MagicalGirlLyricalNanoha'', ''LightNovel/TheFamiliarOfZero'', ''VisualNovel/SteinsGate'', ''Franchise/BlackRockShooter'', ''Anime/DogDays'', ''VisualNovel/FateStayNight'', and even the popular doujin series which is the ''Franchise/TouhouProject'', in cute Nendoroid forms in a story that no one seems to bother understanding.

* ''VideoGame/LittleBigPlanet'' can become this by combining DownloadableContent, you can have Franchise/{{Batman}}, [[Film/BackToTheFuture Marty McFly]], Franchise/SpiderMan and [[WesternAnimation/TheNightmareBeforeChristmas Jack Skellington]] in [[Franchise/TheMuppets the Muppet Theater]], or [[Franchise/ToyStory Buzz Lightyear]], [[WesternAnimation/TheIncredibles Mr. Incredible]], [[Franchise/PiratesOfTheCaribbean Jack Sparrow]] and WesternAnimation/{{SpongeBob|SquarePants}} in [[WesternAnimation/AdventureTime the Land of Ooo]].

Heroes from ''{{VideoGame/Warcraft}}'', ''{{VideoGame/Starcraft}}'', ''{{VideoGame/Diablo}}'' and ''VideoGame/{{Overwatch}}'' get mixed up with a multiverse ExcusePlot and fight to the death across different battlegrounds. Eventually, characters from Blizzard's non-franchise titles, like ''VideoGame/{{Blackthorne}}'' or ''VideoGame/TheLostVikings'' may join.

* Yet another pastiche of ''SRW'' would be ''VideoGame/BattleMoonWars'' which merges the three major published {{Franchise/Nasuverse}} canons together: ''VisualNovel/{{Tsukihime}}'', ''VisualNovel/FateStayNight'', and ''LightNovel/TheGardenOfSinners''.

* ''Dengeki Gakuen RPG: Cross of Venus'' is a UsefulNotes/NintendoDS ActionRPG that throws ''LightNovel/ShakuganNoShana'', ''LightNovel/IriyaNoSoraUFONoNatsu'', ''LightNovel/KinosJourney'', ''LightNovel/ACertainMagicalIndex'', ''LightNovel/HarukaNogizakasSecret'', ''Literature/BludgeoningAngelDokurochan'', ''LightNovel/{{Toradora}}'' and ''LightNovel/AsuraCryin''' (with cameos from ''Literature/SpiceAndWolf'', ''LightNovel/{{Baccano}}'', ''LightNovel/{{Inukami}}'' and the LightNovel/BoogiepopSeries) together into a CrisisCrossover.

Part of the reason for the game's obscurity lies in the fact that it was never given an English version, nor did anyone make an English patch.
** It was said that Shana from ''LightNovel/ShakuganNoShana'' and Madoka from ''Anime/PuellaMagiMadokaMagica'' would appear in the game as DLC characters, but there seems to be no evidence aside from them being in the character lists on various websites.

* ''Fantasia Re:Build'' is an RPG set to release on [=iOS=] and Android devices this year that is a Crossover between various light novel series under Kadokawa's Fantasia Bunko imprint, including ''LightNovel/HowToRaiseABoringGirlfriend'', ''Literature/SkyWizardsAcademy'', ''LightNovel/ChromeShelledRegios'', ''LightNovel/{{Slayers}}'', ''LightNovel/AntiMagicAcademyThe35thTestPlatoon'', ''LightNovel/TheLegendOfTheLegendaryHeroes'', ''LightNovel/DateALive'', ''LightNovel/TokyoRavens'', ''LightNovel/CoffinPrincessChaika'', ''LightNovel/Gamers2015'', ''LightNovel/HighSchoolDXD'', ''LightNovel/AkashicRecordsOfBastardMagicInstructor'', and ''LightNovel/FullMetalPanic''.

** First there was the ''[[http://www.nick.co.uk/games/nickelodeon-super-brawl-world/s1ri7l Nickelodeon Super Brawl World]]'' browser game. Years later, the company went full ''Super Smash Bros.'' with ''VideoGame/NickelodeonAllStarBrawl'', which even included ''Franchise/{{Garfield}}'', who had been purchased by Nick but had yet to get his show by the game's release.

* The ''VideoGame/SuperSmashBros'' series centers around having a huge assortment of different Creator/{{Nintendo}} characters duking it out, from powerhouse franchises like ''Franchise/SuperMarioBros'' and ''Franchise/{{Pokemon}}'' to one-off retro games like ''VideoGame/IceClimber'' and ''VideoGame/DuckHunt''.
** With ''[[VideoGame/SuperSmashBrosBrawl Brawl]]'' (the third iteration), the series took it a step further by adding third-party {{Guest Fighter}}s to the mix, with Creator/{{Konami}}'s Solid Snake from the ''Franchise/MetalGear'' series and Creator/{{Sega}}'s VideoGame/SonicTheHedgehog joining the fight.[[note]]''Sonic'' was actually intended to be in Melee, but by the time Creator/MasahiroSakurai could ask Sega, the game was too far along its (already brutal) development. Similarly, Creator/HideoKojima wanted Snake in Melee, but he requested too late in Melee's development.[[/note]]

** Fully realized in ''VideoGame/SuperSmashBrosUltimate'' for UsefulNotes/NintendoSwitch: '''''every playable character in Smash Bros. history is selectable''''' (''and then some''). The game even has more content from third-parties, with Simon and Richter Belmont from Konami's ''Franchise/{{Castlevania}}'' and Ken from ''Franchise/StreetFighter'' as fighters and Creator/{{Konami}}'s VideoGame/{{Bomberman}}, Yacht Club Games's VideoGame/ShovelKnight, and Rathalos from Creator/{{Capcom}}'s ''VideoGame/MonsterHunter'' as [[AssistCharacter Assist Trophies]], with the latter also being a boss. And with DLC, you may add Joker from ''VideoGame/Persona5'', heroes of ''Franchise/DragonQuest'', [[VideoGame/BanjoKazooie Banjo & Kazooie]], Terry from ''VideoGame/FatalFury'', Steve from ''VideoGame/{{Minecraft}}'', Sephiroth from ''VideoGame/FinalFantasyVII'', Kazuya from ''VideoGame/{{Tekken}}'', and Sora from ''Franchise/KingdomHearts'' to the mix. All told, there's more than ''thirty different game franchises'' represented in the playable characters alone, and dozens more when you count stages, music, assist trophies, Mii costumes, and spirits, such as ''VideoGame/VirtuaFighter'', ''VideoGame/SimCity'', ''VideoGame/{{Rayman}}'', ''VideoGame/{{Tetris}}'', ''VideoGame/{{Galaga}}'', ''Franchise/AssassinsCreed'', ''VideoGame/{{Undertale}}'', ''VideoGame/{{Cuphead}}'', ''VideoGame/MetalSlug'', ''VideoGame/{{Fallout}}'', ''VideoGame/{{Warframe}}'', ''Franchise/ResidentEvil'', ''VideoGame/NoMoreHeroes'', ''VideoGame/{{Shantae}}'', ''VideoGame/DevilMayCry'', ''Franchise/TheElderScrolls'', and ''VideoGame/{{Doom}}''. By the time the game's DLC cycle ended, the playable roster alone had fighters from '''40''' different series.

* ''VideoGame/CastlevaniaHarmonyOfDespair''. Dracula's come to life inside a book chronicling his various reincarnations. Unfortunately for him, so have [[VideoGame/CastlevaniaChroniclesOfSorrow the guy that beat him for good, his reluctant reincarnation following that defeat, their witch friend]], [[VideoGame/CastlevaniaSymphonyOfTheNight Dracula's human-sympathising son, the Belmont that said son freed from mind control, the girl that helped them]], [[VideoGame/CastlevaniaI the Belmont Dracula cursed, who then killed Drac ''again'' to beat said curse]], [[VideoGame/CastlevaniaOrderOfEcclesia an amnesiac with magic siphoning powers]], [[VideoGame/CastlevaniaPortraitOfRuin the duo that beat him and Death at the same time]], and [[VideoGame/GetsuFumaDen Getsu Fuma]].

** Similarly, ''Battle Stadium D.O.N.'' is the same, but specifically has characters from ''Manga/DragonBall'', ''Manga/OnePiece'', and ''Manga/{{Naruto}}'' (hence the D.O.N.).

* NES pirate cartridge ''VideoGame/KartFighter'' drops the characters from ''VideoGame/SuperMarioKart'' into a fighting game, while ''World Heroes 2'' (not to be confused with the actual ''VideoGame/WorldHeroes'' games) includes [[Franchise/StreetFighter Ryu, Chun Li, M. Bison]], [[VideoGame/FinalFight Haggar]], [[VideoGame/FatalFury Andy Bogard, Lawrence Blood, Mai Shiranui]], [[Franchise/SuperMarioBros Mario, King Koopa]], VideoGame/SonicTheHedgehog, [[Franchise/TeenageMutantNinjaTurtles Leonardo]], and [[Manga/DragonBall Goku]].
** The Mega Drive bootleg ''[[ColonCancer Top Fighter 2000 MK VIII]]'' attempts to take this one step further, (albeit with fewer characters) with UsefulNotes/MuhammadAli, (yes, the legendary boxer) UsefulNotes/MichaelJordan, (yes, the NBA star) [[VideoGame/StreetFighterII Ryu]], [[Manga/DragonBall Goku]], [[VideoGame/TheKingOfFighters Kyo]], ComicBook/{{Cyclops}}, [[VideoGame/FatalFury Ryo and Geese Howard]] all playable characters. The title screen features the former two, while the intro sequence (which includes ''Ali punching Jordan in the face'') implies that they were going for an UltimateShowdownOfUltimateDestiny between them.

* ''Dengeki Gakuen RPG: Cross of Venus'' is a UsefulNotes/NintendoDS ActionRPG that throws ''LightNovel/ShakuganNoShana'', ''LightNovel/IriyaNoSoraUFONoNatsu'', ''LightNovel/KinosJourney'', ''LightNovel/ACertainMagicalIndex'', ''LightNovel/HarukaNogizakasSecret'', ''LightNovel/BludgeoningAngelDokurochan'', ''LightNovel/{{Toradora}}'' and ''LightNovel/AsuraCryin''' (with cameos from ''LightNovel/SpiceAndWolf'', ''LightNovel/{{Baccano}}!'', ''LightNovel/{{Inukami}}!'' and the LightNovel/BoogiepopSeries) together into a CrisisCrossover.
** ''VideoGame/DengekiBunkoFightingClimax'', a traditional fighter for arcade and consoles starring characters from Dengeki Bunko properties, including [[LightNovel/SwordArtOnline Asuna]], [[LightNovel/ShakuganNoShana Shana]], [[LightNovel/ACertainMagicalIndex Mikoto Misaka]], [[LightNovel/{{Oreimo}} Kirino Kousaka]], [[LightNovel/{{Durarara}} Shizuo Heiwajima]], and [[LightNovel/AccelWorld Kuroyukihime]]. Representing Sega's own stake in the game (since they developed it) is [[VideoGame/VirtuaFighter Akira Yuki]] (with Pai Chan as an AssistCharacter), serving as the game's GuestFighter boss. There's no relation between those two titles [[spoiler: except for the same villain, named Zetsumu]].
* ''VideoGame/DreamMixTVWorldFighters'' is a fairly bizarre crossover FightingGame featuring characters from Creator/{{Konami}}, Creator/HudsonSoft, and Creator/{{Takara}}. It's a shame it wasn't very good; where else could you pit VideoGame/{{Bomberman}}, [[Franchise/{{Castlevania}} Simon Belmont]], [[Franchise/MetalGear Solid Snake]] and [[{{Transformers}} Optimus Prime]] against each other?

** ''VideoGame/SuperBomberman R'' and ''Super Bomberman R Online'' both feature a lot playable cameos, ranging from well-known characters from Creator/{{Konami}}'s repertoire like [[VideoGame/{{Castlevania}} Simon Belmont]] and [[Franchise/SilentHill Pyramid Head]], to other recognizable third-parties like [[Franchise/{{Halo}} Master Chief]] and VideoGame/RatchetAndClank, to more out-there choices like [[VideoGame/PrincessTomatoInTheSaladKingdom Princess Tomato]] and [[VideoGame/RumbleRoses Reiko Hinomoto]].

* VideoGame/{{Widenyo}}, a very addicting and [[ForcedLevelGrinding grind-tastic]] turn-based strategy game featuring 156 characters from a multitude of Creator/{{Alicesoft}} games.

* [[VideoGame/OneThousandAndOneSpikes 1001 Spikes]] has many different characters from other games - Commander Video from ''VideoGame/BitTrip'', Sugimoto, President Thompson and Zombie from Tempura of the Dead, Juni from VideoGame/KnyttStories, Nyx from VideoGame/NyxQuest, and Curly Brace from ''VideoGame/CaveStory''. It even has an author avatar of Jonathan Blow (who made VideoGame/{{Braid}} ).

* The ''VideoGame/DarkParables'' series is pretty much this for {{fairy tale}}s. Although there is only one playable character - the Fairy Tale Detective, who resolves the issues preventing HappilyEverAfter - there is an ever-expanding cast of characters from a variety of classic tales, all of whom interact with one another in some way or another. Thus you see things like Literature/SnowWhite's twin brother being engaged to Literature/{{Rapunzel}}, and [[Literature/JackAndTheBeanstalk Jack]] confronting [[Literature/GoldilocksAndTheThreeBears Goldilocks,]] and Literature/{{Pinocchio}}'s father being married to Literature/{{Cinderella}}'s FairyGodmother - among many other connections.
* ''Videogame/{{Tetris}}'' (Bullet-Proof Software, 1989) for the NES: The best ending has Peach clapping, Mario and Luigi dancing, Bowser on accordion, Samus on Cello, Link playing the flute, Pit playing violin, and Donkey Kong on drums.

* ''Fantasia Re:Build'' is an RPG set to release on [=iOS=] and Android devices this year that is a Crossover between various light novel series under Kadokawa's Fantasia Bunko imprint, including ''LightNovel/HowToRaiseABoringGirlfriend'', ''LightNovel/SkyWizardsAcademy'', ''LightNovel/ChromeShelledRegios'', ''LightNovel/{{Slayers}}'', ''LightNovel/AntiMagicAcademyThe35thTestPlatoon'', ''LightNovel/TheLegendOfTheLegendaryHeroes'', ''LightNovel/DateALive'', ''LightNovel/TokyoRavens'', ''LightNovel/CoffinPrincessChaika'', ''LightNovel/Gamers2015'', ''LightNovel/HighSchoolDXD'', ''LightNovel/AkashicRecordsOfBastardMagicInstructor'', and ''LightNovel/FullMetalPanic''.

* ''Heavy Burger'' is a love letter to the Creator/{{Data East}} game library (Now owned by Marvelous via G-Mode), in which you control one of four [[VideoGame/{{BurgerTime}} Peter Peppers]] killing each other on different arcade games of the now-defunct company.

* With ''VideoGame/{{Fortnite}}'' having a lot of Crossover Collaborations, we can have a match forming with Film/JohnWick, Franchise/{{Batman}}, [[Franchise/MarvelCinematicUniverse the Avengers]] and [[Franchise/StarWars the Jedi]] to pit against [[ComicBook/{{Thanos}} Thanos]], the Black Order and the Stormtroopers altogether, with more additions to be added in the future.

* An old (and never finished) ''VideoGame/{{Doom}}'' mod ''[[https://doomwiki.org/wiki/EarthBound_Doom EarthBound Doom]]'' not only had you playing as the protagonists of ''VideoGame/EarthBound'', but added enemies taken from many different shooter games, including ''Heretic'', ''Hexen'', ''Duke Nukem 3D'', ''[[VideoGame/ShadowWarrior1997 Shadow Warrior]]'', as well as one or two monsters from ''VideoGame/{{Blood}}'' and ''Strife''.

** The ''VideoGame/MarvelVsCapcom'' games, (''VideoGame/XMenVsStreetFighter'', ''VideoGame/MarvelSuperHeroesVsStreetFighter'', ''VideoGame/MarvelVsCapcomClashOfTheSuperheroes'', ''VideoGame/MarvelVsCapcom2'' and now ''VideoGame/MarvelVsCapcom3'') pit the characters of the various game series produced by Creator/{{Capcom}} against the heroes and villains of the MarvelUniverse in, naturally, a fighting tournament. Only the sketchiest rationale is drawn for this.

* With the inclusion of [[VideoGame/TheLegendOfZelda Link]], [[VideoGame/AnimalCrossing Villager]] and [[VideoGame/AnimalCrossing Isabelle]] as DLC and [[VideoGame/{{Splatoon}} the Inklings]] in the UpdatedReRelease, as well as [[VideoGame/FZero the Blue Falcon]] as a kart and [[VideoGame/FZero Mute City, Big Blue]] and [[VideoGame/{{Excite}} Excitebike Arena]] as tracks, ''VideoGame/MarioKart8'' becomes this, to an extent.

*** And then ''Project X Zone 2'', the sequel, [[UpToEleven added Nintendo Characters into the mix]] (Specifically Fiora from ''VideoGame/XenobladeChronicles1'' and Chrom and Lucina from ''VideoGame/FireEmblemAwakening'').

* Capcom's own MascotFighter: ''VideoGame/CapcomFightingEvolution''. The only game where we were able to have a [[StreetFighter Zangief vs. Alex]] fight[[note]]Before the release of ''VideoGame/StreetFighterV'' anyway[[/note]], and which not only had the distinction of being the only Capcom-made[[note]]''VideoGame/SNKVsCapcomSVCChaos'' doesn't count, it was made by {{Creator/SNK}}[[/note]] crossover not featuring [[VideoGame/{{Darkstalkers}} Morrigan]], (Anakaris, Demitri, Felicia and Jedah, plus Pyron as one of the final bosses, were the VideoGame/{{Darkstalkers}} representants) but also the only game where we were able to fight as one (or two) of the ''VideoGame/RedEarth'' characters who aren't Tessa. (Leo, Hauzer, Hydron and Kenji were the representants)

** ''VideoGame/StreetFighterXTekken'' and ''Tekken x Street Fighter'' however are actual fighting games featuring Namco (''VideoGame/{{Tekken}}'') and Capcom (''StreetFighter'') characters.

* ''VideoGame/DeadByDaylight'' started off with only original characters, but over several [=DLC=] patches, began adding licensed characters and maps from horror movies, tv-shows, and other video games. This started with Michael Myers and Laurie Strode from ''Franchise/{{Halloween}}'', Bill from ''VideoGame/Left4Dead'', Leatherface from ''Film/TheTexasChainsawMassacre'', Freddy Krueger and Quentin Smith from ''Franchise/ANightmareOnElmStreet'', Amanda Young and David Tapp from ''Franchise/{{Saw}}'', Ghostface from ''Film/{{Scream}}''[[note]]The character underneath the mask is a CanonForeigner; only the mask and name are licensed, because the rights to the mask and the movie are separate.[[/note]], Ash from ''Franchise/EvilDead'', the Demogorgon, Nancy Wheeler and Steve Harrington from ''Series/StrangerThings'', Pyramid Head and Cheryl Mason from ''Franchise/SilentHill'', Nemesis, Jill Valentine, and Leon Kennedy from ''Franchise/ResidentEvil'', and Pinhead from ''Franchise/{{Hellraiser}}''. Skins based off of characters from the web series ''WebVideo/CryptTV'' were also added for some of the game's original characters.

** Fully realized in ''VideoGame/SuperSmashBrosUltimate'' for UsefulNotes/NintendoSwitch: '''''every playable character in Smash Bros. history is selectable''''' (''and then some''). The game even has more content from third-parties, with Simon and Richter Belmont from Konami's ''Franchise/{{Castlevania}}'' and Ken from ''Franchise/StreetFighter'' as fighters and Creator/{{Konami}}'s VideoGame/{{Bomberman}}, Yacht Club Games's VideoGame/ShovelKnight, and Rathalos from Creator/{{Capcom}}'s ''VideoGame/MonsterHunter'' as [[AssistCharacter Assist Trophies]], with the latter also being a boss. And with DLC, you may add Joker from ''VideoGame/Persona5'', heroes of ''Franchise/DragonQuest'', [[VideoGame/BanjoKazooie Banjo & Kazooie]], Terry from ''VideoGame/FatalFury'', Steve from ''VideoGame/{{Minecraft}}'', Sephiroth from ''VideoGame/FinalFantasyVII'', Kazuya from ''VideoGame/{{Tekken}}'', and Sora from ''Franchise/KingdomHearts'' to the mix. All told, there's more than ''thirty different game franchises'' represented in the playable characters alone, and dozens more when you count stages, music, assist trophies, Mii costumes, and spirits, such as ''VideoGame/VirtuaFighter'', ''VideoGame/SimCity'', ''VideoGame/{{Rayman}}'', ''VideoGame/{{Tetris}}'', ''VideoGame/{{Galaga}}'', ''Franchise/AssassinsCreed'', ''VideoGame/{{Undertale}}'', ''VideoGame/{{Cuphead}}'', ''VideoGame/MetalSlug'', ''VideoGame/{{Fallout}}'', ''VideoGame/{{Warframe}}'', ''Franchise/ResidentEvil'', ''VideoGame/NoMoreHeroes'', ''VideoGame/{{Shantae}}'', ''VideoGame/DevilMayCry'', ''Franchise/TheElderScrolls'', and ''VideoGame/{{Doom}}''.
