History Crossover / VideoGames

** Perhaps less crossover than {{cameo}} but the fates of the characters from the TV show of ''TabletopGame/DungeonsAndDragons'' is on a wall in ''Baldur's Gate II''.

* Every ''Mario'' game that Creator/SquareEnix has worked on (''VideoGame/SuperMarioRPG'', ''VideoGame/FortuneStreet'', and ''Mario Hoops 3-on-3'') has included characters from their own series in some form. ''SMRPG'' features a BonusBoss utilizing the boss, victory, and Prelude themes from ''VideoGame/FinalFantasyIV'', ''Hoops'' features [[VideoGame/FinalFantasyI a Ninja, a White Mage, a Black Mage,]] a Moogle, and a Cactuar as unlockable characters, and roughly half the roster of ''FS'' is made up of ''VideoGame/DragonQuest'' characters (with some ''Final Fantasy'' characters appearing in [[NoExportForYou previous Japan-only installments]]).

* Sega's VideoGame/{{Maimai}} arcade game enjoys doing this every now and then.
** The SEGA section is ExactlyWhatItSaysOnTheTin. The songs are from SEGA games, like [[VideoGame/SonicTheHedgehog Live and Learn]], [[VideoGame/BurningRangers Angels With Burning Hearts]], and [[VideoGame/PhantasyStarUniverse Save This World]].

* ''VideoGame/MarioAndSonicAtTheOlympicGames'', a MassiveMultiplayerCrossover of the two [[Franchise/SuperMarioBros biggest]] [[VideoGame/SonicTheHedgehog mascots]] in video games and their ensemble competing in the Olympic Games.

** ''Mario Kart 8'' includes characters, karts, and stages from ''Franchise/TheLegendOfZelda'', ''VideoGame/{{Excitebike}}'', ''VideoGame/FZero'', and ''VideoGame/AnimalCrossing'' in its DLC. The UpdatedRerelease ''Mario Kart 8 Deluxe'' adds the Inklings from ''Franchise/{{Splatoon}}'' and a battle stage based on the first game's Urchin Underpass stage as well.
* ''VideoGame/{{Mari0}}'' is a fan-made {{freeware|games}} crossover between ''VideoGame/SuperMarioBros'' and ''VideoGame/{{Portal}}''. You play as Mario... except you have a portal gun.

** Its sister series, ''VideoGame/RakenzarnFrontierStory'', is this as well with the added premise of AlternateUniverse. It's possible this is an even BIGGER crossover than Rakenzarn Tales since we'll be seeing different versions of characters. This includes two versions of Mario: the Mario we all know and love... and the Mario from Series/TheSuperMarioBrosSuperShow.

** While the roster of Nintendo characters was small in [[VideoGame/SuperSmashBros64 the original game]], it increased considerably in ''VideoGame/SuperSmashBrosMelee'', which not only added more characters to the existing universes but also went as far as introducing characters from franchises that were relatively obscure back then, such as the [[VideoGame/IceClimber the Ice Climbers]], [[Franchise/FireEmblem Marth and Roy]], and [[VideoGame/GameAndWatch Mr. Game & Watch]].
** Starting with ''VideoGame/SuperSmashBrosBrawl'', it's also crossed-over with third-party characters [[VideoGame/MetalGearSolid Solid Snake]] and VideoGame/SonicTheHedgehog. ''VideoGame/SuperSmashBrosForNintendo3DSAndWiiU'' extends it with VideoGame/PacMan, Franchise/MegaMan, [[Franchise/StreetFighter Ryu (and later, Ken)]], [[VideoGame/FinalFantasyVII Cloud Strife (and later, Sephiroth)]], and VideoGame/{{Bayonetta}}. As of ''VideoGame/SuperSmashBrosUltimate'', [[VideoGame/{{Castlevania}} Simon and Richter Belmont]], [[VideoGame/Persona5 Joker]], the Heroes of ''Franchise/DragonQuest'' [[labelnote:*]] specifically, those of [[VideoGame/DragonQuestXI XI]], [[VideoGame/DragonQuestIII III]], [[VideoGame/DragonQuestIV IV]] and [[VideoGame/DragonQuestVIII VIII]][[/labelnote]], [[VideoGame/BanjoKazooie Banjo & Kazooie]], [[VideoGame/FatalFury Terry Bogard]], [[VideoGame/{{Minecraft}} Steve]], [[VideoGame/{{Tekken}} Kazuya Mishima]], and [[Franchise/KingdomHearts Sora]] have all joined as well.

* ''VideoGame/StarlinkBattleForAtlas'' features ''VideoGame/StarFox'' characters in a original storyline in the Switch version.

* ''Iron Man and X-O Manowar in Heavy Metal'' is a cross over between ComicBook/IronMan and ComicBook/XOManowar. There was also a comic.

* ''[[LightNovel/IsItWrongToTryToPickUpGirlsInADungeon DanMachi]]: VideoGame/MemoriaFreese'':
** The ''LightNovel/KinosJourney'' crossover, ''Travelers and the Labyrinth Country'' featured Kino herself(In both three and four-star, plus the schoolgirl version from ''LightNovel/GakuenKino'' when it was added during the rerun.), Shizu, and Photo, as well as Hermes(the god), dressed as Kino, as [[PlayerCharacter Adventurers]], while Ti alongside Hestia, who was dressed as Photo, was an assist.

** ''Dungeon and Goblins'' crosses over with ''LightNovel/GoblinSlayer''. Appearing characters include Goblin Slayer himself, Priestess, Noble Fencer, High Elf Archer, Sword Maiden, and Cowgirl. Cowgirl and Heavy Warrior-dressed variants of Chigusa and Ouka respectively also appeared. Sword Maiden as well as forms of Amid and Ryu dressed as Sword Maiden and High Elf Archer respectively also appeared during part 2.

* ''VideoGame/GranblueFantasy'' is not only a FantasyKitchenSink within its own universe, but it's also so in a meta sense, as it has been the host of several events meant to join the universes of different copyrights with itself. At the time of this writing it has crossed over with ''Franchise/StreetFighter'', ''VideoGame/TheIdolmasterCinderellaGirls'', ''LightNovel/{{Slayers}}'', the ''VideoGame/TalesSeries'', ''VideoGame/SakuraWars'', ''VideoGame/SamuraiShodown'', ''Anime/KatsugekiToukenRanbu'', ''Manga/CardcaptorSakura'', ''Manga/AttackOnTitan'', ''Anime/LoveLive'' and ''VideoGame/Persona5''.

** Non-Yoko Taro works included for crossover events are ''Tsuri Star'', ''VideoGame/SpaceInvaders'', ''VideoGame/FinalFantasyBraveExvius'', ''Anime/CodeGeass'', ''LightNovel/ReZero'', ''VisualNovel/HigurashiWhenTheyCry'', ''Manga/RozenMaiden'' and virtual idol group Gems Company[[labelnote:note]]The group's music is composed by [[Music/{{MONACA}} the same group]] who did the music for ''[=SINoALICE=]''[[/labelnote]].

** Starting with ''Super Smash Bros. Brawl'', it's also crossed-over with third-party characters [[VideoGame/MetalGearSolid Solid Snake]] and VideoGame/SonicTheHedgehog. The Wii U and 3DS games extend it with VideoGame/PacMan, Franchise/MegaMan, [[Franchise/StreetFighter Ryu (and later, Ken)]], [[VideoGame/FinalFantasyVII Cloud Strife (and later, Sephiroth)]], and VideoGame/{{Bayonetta}}. As of ''Ultimate'', [[VideoGame/{{Castlevania}} Simon and Richter Belmont]], [[VideoGame/Persona5 Joker]], the Heroes of ''Franchise/DragonQuest'' [[labelnote:*]] specifically, those of [[VideoGame/DragonQuestXI XI]], [[VideoGame/DragonQuestIII III]], [[VideoGame/DragonQuestIV IV]] and [[VideoGame/DragonQuestVIII VIII]][[/labelnote]], [[VideoGame/BanjoKazooie Banjo & Kazooie]], [[VideoGame/FatalFury Terry Bogard]], [[VideoGame/{{Minecraft}} Steve]], [[VideoGame/{{Tekken}} Kazuya Mishima]], and [[Franchise/KingdomHearts Sora]] have all joined as well. Other characters from other series are also represented through [[VirtualPaperDoll Mii Fighter]] costume DLC, including ''VideoGame/VirtuaFighter'' and ''VideoGame/{{Undertale}}''. ''Ultimate'' also features third party Assist Trophy characters who come from series not represented by playable characters like VideoGame/{{Bomberman}}, VideoGame/ShovelKnight, and [[VideoGame/MonsterHunter Rathalos]], as well as characters like ''VideoGame/{{Shantae}}'' and ''VideoGame/{{Rayman}}'' making cameos in Spirits mode.
** Thanks to the first line of Toys/{{amiibo}} being made for Smash Bros, games compatible with amiibo have crossover content ranging from costumes in a ''Manga/OnePiece'' game to the ''Fire Emblem'' characters being playable in ''VideoGame/CodeNameSteam''.

* VideoGame/ClubPenguin has various parties focused around other Creator/{{Disney}} works, where rooms are decorated themed around the work, party-exclusive rooms based on the work, outfits from the work are made available, and the characters are meetable. Some examples include Creator/MarvelComics, ''Franchise/StarWars'', ''Franchise/{{Frozen}}'', ''WesternAnimation/MonstersUniversity'', and ''Franchise/TheMuppets''.

* ''VideoGame/AlchemistCode'' has a lot of collaborations and crossovers with famous series such as ''Anime/FateStayNight'', ''VideoGame/{{Disgaea}}'', ''Anime/FullmetalAlchemist'' and so on. However, the most notable crossover is with the game ''VideoGame/PhantomOfTheKill'' as not only they frequently collab with each other, but also they were published by the same company that published them, Fuji Games for Japanese version while Gumi Inc. is for the Global version.

** Way before that, thanks to [[GameMod players modding the game]], you can have various characters from many other games be playable within Left 4 Dead and Left 4 Dead 2.

* ''VideoGame/HeroesOfTheStorm'' is a MOBA which crosses over Creator/BlizzardEntertainment's [[VideoGame/{{Warcraft}} magnum]] [[VideoGame/StarCraft opus]] [[VideoGame/{{Diablo}} games]], [[VideoGame/{{Overwatch}} the newest one]], and [[VideoGame/TheLostVikings some of their classics]] into one big fun brawl.

* ''VideoGame/StarCraft'' had an unofficial crossover with ''Manga/RanmaOneHalf'' in a campaign called Vision of the Future. Unfortunately, the file is currently unavailable as the site that had it expired.

* ''VideoGame/AliensVsPredator''. The Atari Jaguar game and the two PC games are considered classics in the [[FirstPersonShooter FPS]] genre.
* ''[[VideoGame/AllStarFighters All-Star Fighters]]'' is a crossover of the various games made by Creator/D3Publisher from its Simple series of budget games, of which the most notable include the VideoGame/{{Onechanbara}} series and VideoGame/EarthDefenseForce series.

* ''VideoGame/AstroBoyOmegaFactor'' is a CrossOver action game of ''Anime/AstroBoy'' and other works by Creator/OsamuTezuka.
* In the Story Mode of ''VideoGame/BattlePrincessMadelyn'', Don Ramiro of fellow [[VideoGame/GhostsNGoblins GnG-alike]] ''VideoGame/MalditaCastilla'' shows up to give Madelyn advice and aid when she travels to his native Spain.

* Blockland has a [[VideoGame/{{Roblox}} ROBLOXian]] add-on that can make it be this.

* ''VideoGame/CrashBandicootPurpleRiptosRampage'' and ''VideoGame/SpyroOrangeTheCortexConspiracy''. Both games features [[Franchise/SpyroTheDragon Spyro]] and [[VideoGame/CrashBandicoot Crash]] teaming up to defeat their respective enemies: Ripto and Dr. Cortex.

* While we're at it, the first official mod for ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', after the long-awaited HD Texture Pack... was a collaborative effort between Valve and Bethesda, showing just where that [[EnsembleDarkhorse adorable little]] [[VideoGame/{{Portal2}} Space Core]] wound up.

** The Nintendo Switch release of Skyrim allows you to find items from ''VideoGame/{{The Legend of Zelda}}'' series, such as Link's Tunic from ''[[VideoGame/TheLegendOfZeldaBreathOfTheWild Breath of The Wild]]'', the Master Sword, and the Hylian Shield.

** Special mention goes to ''[[VideoGame/CodenameSTEAM Codename: S.T.E.A.M.]]'', which is a Steampunk game with historical characters and fables. AND Marth, Ike, Robin, and Lucina, if you have their amiibo.

** ''Forza Motorsport 6'' features the Chryslus Rocket 69 from ''VideoGame/{{Fallout 4}}'' as DLC.

** [[VideoGame/{{Shadowverse}} Shadowverse]] from the same company has started to make crossovers with various franchises allowing you to play as characters from those. As of writing it's limited to ''VisualNovel/FateStayNight'' and ''Franchise/StreetFighter'', so it's very possible to have an epic battle where Ryu faces Saber ... using a [[WebVideo/{{YuGiOhTheAbridgedSeries}} children's card game]]
* ''VideoGame/HalfLife'' and ''VideoGame/{{Portal}}'' were originally different universes altogether. ([=GLaDOS=] vaguely alludes to the events of Half-Life once in passing, but that was just an easter egg.) But then! In ''VideoGame/{{Portal 2}}'' you can find the drydock for a ship called the Borealis, and ''VideoGame/HalfLife2: Episode 2'' ends with Gordon Freeman about to set off to find it.

* ''VideoGame/HeroesOfTheStorm'' is a MOBA which crosses over Creator/BlizzardEntertainment's [[VideoGame/{{Warcraft}} magnum]] [[VideoGame/{{Starcraft}} opus]] [[VideoGame/{{Diablo}} games]], [[VideoGame/{{Overwatch}} the newest one]], and [[VideoGame/TheLostVikings some of their classics]] into one big fun brawl.

*** [[VideoGame/GanbareGoemon Goemon]] ("Ganbare Goemon Medley")

* ''{{VideoGame/MUGEN}}'' is technically the ultimate crossover game, as, for example, you can fight a Touhou character with a ''Franchise/MortalKombat'' character. That's just a basic example, as well!

* [[VideoGame/NightsIntoDreams NiGHTS]] is featured in both of the ''VideoGame/SonicAdventure'' [[VideoGame/SonicAdventure2 games]], and while he bears no real significance to the plot, he is a part of a level in each, moreso in ''VideoGame/SonicAdventure''.

** ''Dead or Alive 5'' has [[GuestFighter Guest Fighters]] from VideoGame/VirtuaFighter and [[VideoGame/FatalFury S]][[VideoGame/TheKingOfFighters NK]] appear, as well as Naotora Ii from ''VideoGame/SamuraiWarriors''
* ''VideoGame/PAYDAYTheHeist'', with its gameplay so inspired by ''VideoGame/Left4Dead'', went the full mile and released a heist based on Mercy Hospital from ''[=L4D=]'''s "No Mercy" campaign.
* ''VideoGame/PAYDAY2'' takes it even further and has (at last count) had a crossover with [[VideoGame/HotlineMiami Hotline Miami]] [[VideoGame/HotlineMiami2WrongNumber and its sequel]], Franchise/JohnWick, [[VideoGame/CounterStrike Counter Strike: Global Offensive]], Swedish DJ Alesso, The [[Film/PointBreak Point Break 2015 reboot]], [[Film/HardcoreHenry Hardcore Henry]], [[VideoGame/GoatSimulator Goat Simulator]], [[Film/Scarface1983 Scarface]], Film/ReservoirDogs, VideoGame/{{Speedrunners}}, and VideoGame/EnterTheGungeon.

* ''VideoGame/PokerNightAtTheInventory'' has [[VideoGame/TeamFortress2 the RED Heavy]], [[WebAnimation/HomestarRunner Strong Bad]], [[Webcomic/PennyArcade Tycho]], and [[VideoGame/SamAndMaxFreelancePolice Max]] get together for a game of poker. The sequel adds [[VideoGame/SamAndMaxFreelancePolice Sam]], [[VideoGame/{{Borderlands}} Claptrap]], [[WesternAnimation/TheVentureBrothers Brock Samson]], and [[Franchise/EvilDead Ash Williams]], with [[VideoGame/{{Portal}} GLaDOS]] as the dealer.
* Pop 'n Pop, an obscure puzzle game does this with both the gameplay and the characters. The gameplay is essentially [[VideoGame/BubbleBobble Puzzle Bobble]] with a few elements from ''VideoGame/SpaceInvaders'' thrown in while the roster is made up of characters from various Taito arcade games.
** Averted in North America, [[DolledUpInstallment where it was rebranded as a ''Yogi Bear'' game]].

** Ran's classmate, the unnamed [[ClassRepresentative Chairperson]], also happens to study Dan's self-invented martial art, Saikyo-ryu, with [[JokeCharacter predictable results]].

** Another crossover event with ''VideoGame/Drakengard3'' featured Zero, One, Accord and Mikhail [[spoiler: in human and dragon form]], as well as some weapons (including weapons from the first 2 ''Drakengard'' games) and enemies from that franchise [[spoiler:like the Intoners turned into Nightmares]]. The event's revival in June 2019 later added [[spoiler: Two, Three, Four and Five]].
** The third Yoko Taro work to get a crossover event is the original ''VideoGame/NieR'' (specifically the ''Replicant'' version), with both versions of Brother Nier, Kaine, a human Emil and Devola and Popola as a single character being playable. The June 2020 revival run adds [[spoiler: Yonah as well as the King of Facade as a double unit with Fyra.]]
** Non-Yoko Taro works included for crossover events are ''Tsuri Star'', ''VideoGame/SpaceInvaders'', ''VideoGame/FinalFantasyBraveExvius'', ''Anime/CodeGeass'', ''LightNovel/ReZero'', ''VisualNovel/HigurashiWhenTheyCry'', ''Manga/RozenMaiden'' and virtual idol group Gems Company[[labelnote:note]]The group's music is composed by [[Music/{{MONACA}}the same group]] who did the music for ''[=SINoALICE=]''[[/labelnote]]. From the ''LightNovel/ThatTimeIGotReincarnatedAsASlime'' event onwards, crossover events will be held simultaneously between the JP and Global servers.

* Every ''Mario'' game that Creator/SquareEnix has worked on (''VideoGame/SuperMarioRPG'', ''VideoGame/FortuneStreet'', and ''Mario Hoops 3 on 3'') has included characters from their own series in some form. ''SMRPG'' features a BonusBoss utilizing the boss, victory, and Prelude themes from ''VideoGame/FinalFantasyIV'', ''Hoops'' features [[VideoGame/FinalFantasyI a Ninja, a White Mage, a Black Mage,]] a Moogle, and a Cactuar as unlockable characters, and roughly half the roster of ''FS'' is made up of ''VideoGame/DragonQuest'' characters (with some ''Final Fantasy'' characters appearing in [[NoExportForYou previous Japan-only installments]]).

** Starting with ''Super Smash Bros. Brawl'', it's also crossed-over with third-party characters [[VideoGame/MetalGearSolid Solid Snake]] and VideoGame/SonicTheHedgehog. The Wii U and 3DS games extend it with VideoGame/PacMan, [[Franchise/MegaMan Mega Man]], [[Franchise/StreetFighter Ryu (and later, Ken)]], [[VideoGame/FinalFantasyVII Cloud Strife (and later, Sephiroth)]], and VideoGame/{{Bayonetta}}.

* Namco's ''Tales of the World'', starting with ''Nakiri Dungeon 3'', and including the ''Radiant Mythology'' spin-offs, take characters from all the ''VideoGame/TalesOf'' titles, which otherwise only exist as [[SpiritualSuccessor spiritual sequels.]]

** [[RuleOfThree And there's another for the 1.4.3]], this time it was a massive crossover update with [[VideoGame/DontStarve Don't Starve Together]]. On Terraria's end, it received the Deerclops, as well as Chester and a whole lot of new items. There was even a secret seed that allows the world made with it to mimic Don't Starve Together's darkness and hunger mechanics. And for Don't Starve, it received the Eye of Cthulhu ([[AdaptationNameChange which is known as the Eye of Terror]]), an eyeball pet, and some additional items. Fittingly, due to the [[BossFight selling]] [[{{Cyclops}} points]] of these updates- it was known as the Eye for an Eye update.
* ''VideoGame/UnderNightInBirth'' featured two [[GuestFighter Guest Fighters]] in the game's "Ex: Late" update: Eltnum, implied to be Sion Eltnum Altasia from ''VideoGame/MeltyBlood''; and Akatsuki, the protagonist of ''VideoGame/AkatsukiBlitzkampf''.

* Even the venerable ''VideoGame/MarioKart'' series does this... although ''most'' of the characters are Marioverse stalwarts, Donkey Kong and Diddy Kong are their ''VideoGame/DonkeyKongCountry'' incarnations. Being co-developed by Namco, the ''Mario Kart GP'' arcade games go further than the home console versions and include characters from Pac-Man.

* ''7.62 High Caliber'' has a mod named ''Blue Sun'', which turns the native game in a cross-over with ''VideoGame/JaggedAlliance 2''[[note]]''7.62 High Caliber'' being the official sequel of ''Brigade E5: New Jagged Union'', SpiritualSuccessor to the ''Jagged Alliance'' series[[/note]]: there are dialog lines mentionning the country Arulco (''7.62 High Caliber'' being set in another BananaRepublic suffering from a civil war), several dozen of mercenaries from the ''Jagged Alliance'' series can be hired, the weaponseller Bobby Ray can be contacted by radio, a sidequest involves Elliot who fled Arulco to escape from Deidrenna's constant brutality, etc.

* The finale of ''VideoGame/GhostRecon: Advanced Warfighter 2'' has the Ghosts call in an air strike, and in ''VideoGame/{{HAWX}}'', you get to play the mission from the jet fighters' point of view. A similar crossover occurs between ''VideoGame/GhostReconFutureSoldier'' and ''HAWX 2''.

** ''Ais Catastrophe'' crosses over with ''LightNovel/DateALive'', During the event in its first run, it had two sets of summon-able characters. The ''Date'' set features Tohka and a Ais(dressed as Tohka's inverse form) as Adventurers while also featuring Kotori as an assist. The ''Live'' set featured Kurumi and Origami as adventurers while Hestia, dressed as Kotori, can be summoned as an assist. Kaguya can also be earned as an assist by clearing the event story.

* The finale of ''VideoGame/GhostRecon: Advanced Warfighter 2'' has the Ghosts call in an air strike, and in ''VideoGame/{{HAWX}}'', you get to play the mission from the jet fighters' point of view. A similar crossover occurs between ''Future Soldier'' and ''HAWX 2''.

* ''VideoGame/MarioPlusRabbidsKingdomBattle''; as its name suggests, crosses the ''Mario'' franchise with the ''VideoGame/RavingRabbids'' franchise.

* Crossover/IdentityV

* VideoGame/BraveFrontier has recruitable characters from VideoGame/ChainChronicle and vice versa. The characters may come from separate universes, but they are naturally under the same game ownership of Gumi.

* ''VideoGame/{{Rage}}'' has [[Franchise/{{Doom}} Space Marine]] and [[VideoGame/{{Fallout}} Vault Boy]] bobbleheads.

* The ''VideoGame/RivalSchools'' games have had a few crossovers with Creator/{{Capcom}}'s more popular fighting game series ''VideoGame/StreetFighter''; the most obvious was Sakura Kasugano, Ryu's HeroWorshipper, being a playable character in the console versions of the game. There is also a character known as Ran Hibiki, whose name is almost exactly the same as that of Dan Hibiki. Just what her relationship to him is undetermined, assuming there is a relationship at all and it is not simply an {{homage}}.

* ''VideoGame/GranblueFantasy'' is not only a FantasyKitchenSink within its own universe, but it's also so in a meta sense, as it has been the host of several events meant to join the universes of different copyrights with itself. At the time of this writing it has crossed over with ''VideoGame/StreetFighter'', ''VideoGame/TheIdolmasterCinderellaGirls'', ''LightNovel/{{Slayers}}'', the ''VideoGame/TalesSeries'', ''VideoGame/SakuraWars'', ''VideoGame/SamuraiShodown'', ''Anime/KatsugekiToukenRanbu'', ''Manga/CardcaptorSakura'', ''Manga/AttackOnTitan'', ''Anime/LoveLive'' and ''VideoGame/Persona5''.
** [[VideoGame/{{Shadowverse}} Shadowverse]] from the same company has started to make crossovers with various franchises allowing you to play as characters from those. As of writing it's limited to ''VisualNovel/FateStayNight'' and ''VideoGame/StreetFighter'', so it's very possible to have an epic battle where Ryu faces Saber ... using a [[WebVideo/{{YuGiOhTheAbridgedSeries}} children's card game]]

* ''VideoGame/{{Tamagotchi}}'':
** It's had crossovers most prominently with ''VideoGame/{{Aikatsu}}'' and Creator/{{Sanrio}}.

** The 1997 Mothra Tamagotchi, released as a tie-in to ''Film/RebirthOfMothra2'', allows the player to raise various {{kaiju}} such as Film/{{Mothra}} and Franchise/{{Godzilla}}.
** There's also the toy [[Manga/{{Doraemon}} Doraemontchi]] and the functionally-equivalent Doramitchi.
** The Tamagotchi Nano model, introduced in 2010, has been reused for numerous crossovers since. These include [[Ride/DisneyThemeParks Tokyo Disney]] Easter mascots Usatama and Usapiyo, [[Creator/{{Sanrio}} Gudetama]], [[Franchise/{{Pokemon}} Eevee]], ''VideoGame/PacMan'', and ''Anime/NeonGenesisEvangelion''.

** Perhaps less crossover than {{cameo}} but the fates of the charactera from the TV show of ''TabletopGame/DungeonsAndDragons'' is on a wall in ''Baldur's Gate II''.

* ''VideoGame/PuyoPuyo'' and ''VideoGame/{{Tetris}}'', two popular FallingBlocks games come together for ''Puyo Puyo Tetris''.
