12->''"I'm sorry; can you go back to the part about {{ComicBook/Sonic the Hedgehog|ArchieComics}} meeting MOTHER[[BleepDammit BLEEP]]ING ComicBook/{{SPAWN}}?!"''

15There are {{Crossover}}s between works or universes which seem relatively logical, thanks to them being not too different. And then, there are these...
16
17A Weird Crossover is an unlikely crossover between works different enough, be it in themes, tones (e.g. mixing something very dark with something very upbeat), {{genres}} (e.g. merging a ScienceFiction or {{Horror}} franchise with one set in the normal world, or a specific {{superhero}} in a kind of setting they are usually not associated with), etc. It can be a full work, but there are many examples using it to create [[RealTrailerFakeMovie fake movie trailers]]. Also, there are examples of this trope serving to make a single InUniverse joke, the Weird Crossover work referred InUniverse being a ShowWithinAShow (or an unlikely project existing InUniverse). The trope is usually PlayedForLaughs, the joke being the unlikeliness of the crossover.
18
19For [[MediaNotes/{{Copyright}} obvious reasons]] (though official weird crossovers exist, sometimes involving universes inside the same franchise, shared copyright ownership, or {{Public Domain Character}}s), this trope is often restricted to {{Game Mod}}s, FanArt, FanFic, and various kinds of WebOriginal contents.
20
21Of course, Administrivia/TropesAreTools is in full effect for these types of stories. A well-written Weird Crossover can be an engaging story that preserves the original spirit of both works in a new setting, while a poorly done one can create all sorts of {{Glurge}} and MoodWhiplash that clashes with the tone of the two respective works.
22
23The opposite of CommonCrossover, and a specific form of CrackFic. Canonical (non fanwork) examples turn into SharedUniverse. A SuperTrope to DemographicDissonantCrossover. Related to CrossoverCosmology. Sometimes leads to FakeCrossover. Can overlap with IntercontinuityCrossover, MassiveMultiplayerCrossover, UnexpectedCharacter, and GuestFighter. When the unlikely combination is a mish-mash of generic creatures or concepts (instead of proper references to specific universes) it's a FantasyKitchenSink or a SciFiKitchenSink. Occasionally involved in RealTrailerFakeMovie. Crossovers between works with very different tones and settings are often a StoryBreakerTeamUp.

27!!Works Examples:
28
29[[folder:Advertising]]
30* The Advertising/MAndMs spokescandies have had multiple bizarre commercials that crossover with different brands to promote their products, including ''Franchise/StarWars'', ''Franchise/PiratesOfTheCaribbean'', ''Franchise/{{Shrek}}'', ''Franchise/{{Transformers}}'', ''Franchise/IndianaJones'', ''Literature/TheTwilightSaga'', ''Film/{{Iron Man|Films}}'', ''Film/JurassicWorld'', and of all things, Advertising/{{GEICO}}.
31* While [[Creator/ParamountPlus Paramount Mountain]]'s premise, commercials featuring different characters from Paramount's library isn't weird in of itself, it starts to get weird when [[DemographicDissonantCrossover characters from different demographics start interacting with each other]]. You could [[https://www.facebook.com/ParamountPlus/videos/no-strings-attached-mountain-edition-paramount/4010043105961045/ see a female puppet]] from ''Series/CrankYankers'' flirt with a ''Series/BigBrother'' contestant, or watch [[Series/KeyAndPeele Mr. Garvey]] [[https://www.youtube.com/watch?v=YEdNAzv1LD8 chew out]] a bunch of [[WesternAnimation/BluesCluesAndYou kids]] [[Film/MonsterHighTheMovie show]] [[WesternAnimation/AaahhRealMonsters characters]].
32[[/folder]]
33
34[[folder:Anime & Manga]]
35* ''Manga/CellsAtWork'' [[https://twitter.com/shokumonogatari/status/1408258649579872261?s=20 collab with]] the Japanese release of ''Tale of Food''[[note]]a raising sim RPG set in ''China'', about ''traditional Chinese cuisine'', and centering on the supernatural[[/note]].
36* The ''[[https://www.youtube.com/watch?v=fyp40FVEoPM Gundam vs Hello Kitty Project]]'' was released to [[MileStoneCelebration celebrate the anniversaries]] [[Franchise/{{Gundam}} of]] [[Franchise/HelloKitty both]] series.
37* The ''Manga/FistOfTheNorthStar'' mobile game, ''Legends [=ReVIVE=]'' has had multiple crossovers featuring series with their roots in martial arts such as ''Manga/BakiTheGrappler'', ''Franchise/StreetFighter'' and ''VideoGame/VirtuaFighter''. What was markedly not expected however was [[https://hokuto-revive.sega.com/en/info/detail/0057642baznW.html a crossover]] with, of all possible series, '''''Franchise/SonicTheHedgehog''''' [[MilestoneCelebration celebrating the series' 30th anniversary]].
38* ''Anime/IsekaiQuartet''. The only thing in common with the shows that appear in the crossover is that they're ''isekai'' {{Light Novel|s}} series published by Kadokawa. Other than that, it's really weird to see [[Literature/Overlord2012 the Emperor of Nazarick]] casually speaking with [[Literature/ReZero an ordinary human]], [[Literature/TheSagaOfTanyaTheEvil a soldier]] and [[Literature/KonoSuba a literal goddess]].
39* ''Manga/MoriartyThePatriot'' is a mashup of Literature/SherlockHolmes and Franchise/JamesBond.
40* In the combined 33rd and 34th issue of [[Magazine/ShonenJump Weekly Shonen Jump magazine]] released on July 19, 2021, ''Manga/OnePiece'' had [[https://twitter.com/Eiichiro_Staff/status/1414555146307080194 a crossover]] with, of all things, ''Literature/WheresWally'' (More popularly known in North America as ''Where's Waldo?'').
41[[/folder]]
42
43[[folder:Comic Books]]
44* Both the ''Franchise/{{Alien}}'' and ''Franchise/{{Predator}}'' franchises have had (separate) official ''ComicBook/{{Batman}}'' crossover comics.
45* Perhaps not quite as weird as some of the others listed here but ''Ape Nation'' is a crossover between ''Film/AlienNation'' and ''Franchise/PlanetOfTheApes''. The premise is that the Tenctonese slave ship was sucked into a black hole and arrived on the ape-dominated Earth in the future, landing in the Forbidden Zone. Caan, the captain of the Newcomer ship, has conquest in mind and is opposed by his brother Danada who enters into an alliance with the gorilla General Ollo and a human named Simon, who has the ability to speak. Another major character in the miniseries is named Heston.
46** Creator/BoomStudios crossed the Apes over with ''Film/KingKong'', ''Franchise/StarTrek'' and ''ComicBook/GreenLantern''.
47* ''Creator/ArchieComics'' sometimes makes comics that clash their PG, family-friendly image with adult-aimed series:
48** ''ComicBook/ArchieMeetsThePunisher'', which started off as an actual joke: then-Archie editor-in-chief Victor Gorelick was taking suggestions for a superhero crossover, writer Batton Lash jokingly suggested ''ComicBook/ThePunisher'', and then everyone across Archie and Marvel [[CrazyEnoughToWork steadily realized it actually could work]] (even Lash was surprised when Gorelick took his pitch seriously). The final product is very much written as a tongue-in-cheek affair, with Frank Castle being the most [[FishOutOfWater out of his element in trying to adjust to the wholesomeness of the Archie-verse]], and it was well-received and successful enough that it directly motivated the later crossovers below.
49** An ''ComicBook/ArchieVsPredator'' series started in 2015. It's a horror movie parody full of {{gorn}} and [[HotterAndSexier sexual situations]] parodying teen horror films, and is very clearly self-aware at [[RefugeInAudacity the sheer absurdity of its own premise and just rolls with it]].
50** The popularity of the above caused ''Archie Vs Film/{{Sharknado}}'' to be created.
51** ''ComicBook/SonicTheHedgehogArchieComics'' has an issue where the colorful cast of {{Funny Animal}}s have a brush with the dark, gritty [[NinetiesAntiHero '90s anti-heroes]] of Creator/ImageComics -- complete with a brief appearance from ''ComicBook/{{Spawn}}''. Even though this issue was released post-CerebusSyndrome, crossing a series aimed at children over with such dark and mature (well, mid-'90s "mature") series raised some eyebrows even in its day.
52* Even before Creator/WarnerBrothers absorbed Creator/DCComics, [=DC=] had the license to print Characters/LooneyTunes comics. In 2000, [=DC=] launched the four-issue series ''ComicBook/{{Superman}} and WesternAnimation/BugsBunny'' wherein the wacky Dodo meets Mr. Mxyzptlk, and they form a partnership to wreak havoc on both universes.
53** 2017 had another round of ''DC''/''Looney Tunes'' crossovers. Of particular note was ''Batman/Elmer Fudd'', which focused on how they're not that different and both trapped in a neverending battle with a chaotic enemy (the Joker and Bugs Bunny, respectively).
54** Another ''DC''/''Looney Tunes'' crossover made around the same time paired ComicBook/JonahHex with Yosemite Sam and WesternAnimation/FoghornLeghorn.
55** And let's not even get started on the oddity that is ''[[http://dc.wikia.com/wiki/Superman_Meets_the_Quik_Bunny_Vol_1_1 Superman Meets the Quik Bunny]]''.
56** DC's ''ComicBook/HannaBarberaBeyond'' franchise has given us such gems as a ''ComicBook/SuicideSquad''[=/=]''WesternAnimation/TheBananaSplits'' crossover.
57* ''[[http://dc.wikia.com/wiki/Lobo_Paramilitary_Christmas_Special_Vol_1_1 Lobo's Paramilitary Christmas Special]]'' - aka "Lobo vs Santa" - features ComicBook/{{Lobo}} being hired by the Easter Bunny to whack [[BadassSanta Santa Claus]].
58* There is a very old Disney comic story called "Thumper meets the Seven Dwarfs", where [[WesternAnimation/{{Bambi}} Thumper the rabbit]] encounters the Seven Dwarfs from Disney's ''WesternAnimation/SnowWhiteAndTheSevenDwarfs'', and Friend Owl and Flower also appear, and they even encounter the giant from a WesternAnimation/MickeyMouse cartoon ''WesternAnimation/BraveLittleTailor''!
59* Comic tie-ins for the ''Film/StarTrek2009'' universe had a couple odd crossover choices: DC's ''Star Trek'' meets ComicBook/GreenLantern, IDW's ''Star Trek'' meets ComicBook/LegionOfSuperheroes, Boom! Studios' ''Star Trek'' meets ''Franchise/PlanetOfTheApes''... for a lot of them, the only thing the two properties had in common was that they'd both gotten a recent reboot or film revival.
60** Prior to that, Marvel put out two Star Trek / X-Men crossovers, one as a comics miniseries and one as a ''novel.''
61* When Creator/DynamiteComics owned ''Franchise/EvilDead'', they did some very weird crossovers. Ash meets the Franchise/CthulhuMythos? Well, okay, they both feature a book called the Necronomicon. Ash meets ''Film/{{Darkman}}''? Okay, both Sam Raimi creations. Ash meets ''Series/XenaWarriorPrincess'' [[note]] Which seems to exist only to poke fun at the fact that Bruce Campbell played Autolycus [[/note]], or ''ComicBook/{{Vampirella}}''? Weird.
62* ComicBook/SpiderMan once helped Advertising/CapnCrunch battle the Soggies, though the conclusion to the story was never published.
63* In Brazil, ''[[ComicBook/MonicasGang Monica and Friends]]'', a very popular comic book franchise for kids, had a series of official crossovers in 2018 with the [[ComicBook/JusticeLeagueOfAmerica Justice League]] heroes and their antagonists.
64** The ''Monica Teen'' spin-off manga also crossed over with the Justice League for two issues during the same period. While a ''Monica Teen''/Justice League crossover seems less weird in theory, the weirdness in this case comes from the fact that not only the stories in the two issues are not related to each other, but they also contradict each other in several instances (for example, issue #25 establishes that the Justice League comes from an Main/AlternateUniverse, while in issue #26 all characters exist in the same universe and Monica and her friends have seen the Justice League saving the world for a long time).
65** Speaking of ''Monica Teen'', they have also previously crossed over with Creator/OsamuTezuka's characters, which also managed to show [[Manga/PrincessKnight Sapphire]], Manga/AstroBoy and Manga/KimbaTheWhiteLion interacting with each other, despite coming from different works from Tezuka.
66* ''ComicBook/MyLittlePonyTransformersFriendshipInDisguise'': Granted, they're both owned by Hasbro and have comics published by IDW, but still, this is a comic where giant fighting robots interact with cute talking ponies.
67* ''ComicBook/ScoobyDooTeamUp'', in which the Mystery Inc gang meet a new Creator/DCComics or Creator/HannaBarbera character each month, from classic characters like Batman, Wonder Woman, and The Flintstones to more obscure ones like Hong Kong Phooey or Angel and the Ape.
68* One ComicStrip/{{Garfield}} strip had him joining the Franchise/TeenageMutantNinjaTurtles because he wanted to eat their pizzas, they saw through his disguise when Odie tagged along, he had a turtle shell on his tongue, they beat them up and kicked them out of their lair.
69* With no fanfare, Creator/DCComics dropped a six-issue, Creator/LarryHama miniseries adapting two classic arcade games created by Creator/MidwayGames in the 80s. Which ones? ''VideoGame/SpyHunter'' and...''VideoGame/{{Paperboy}}''.
70* Creator/MarvelComics once had the license to print comic books based on ''WesternAnimation/TheRenAndStimpyShow'' (the patron saint for the GrossoutShow genre). This led to a crossover issue between ComicBook/SpiderMan and Powdered Toast Man because, according to the front cover, "NO ONE demanded it!", apparently.
71* ''Music/{{Eminem}} Vs ComicBook/ThePunisher'', a 2009 collaboration between Marvel and ''XXL'' Magazine.
72* During 2013, [[Creator/IDWPublishing IDW]] held a company-wide CrossThrough event featuring ''Mars Attacks!'', as the Martians invaded the universes and timelines of five different series they've all published back then. Some of those were decidedly weird matchups, namely ''ComicBook/{{Ghostbusters}}'', Music/{{KISS}} and even ''ComicStrip/{{Popeye}}''!
73* An 80s Marvel CrisisCrossover, ''The Evolutionary War'', involved the High Evolutionary, normally an Avengers/X-Men villain. At the time Marvel was doing a comic based on the sitcom ''Series/{{ALF}}'' -- and [[https://www.cbr.com/alf-marvel-evolutionary-war-crossover/ they decided to get ALF involved in the crossover too]].
74[[/folder]]
75
76[[folder:Fan Works]]
77* ''Fanfic/ARESTheGodsOfWar'' sees John-117 and Cortana (and later on others) from ''Franchise/{{Halo}}'' interacting with the FanService heavy world of ''VideoGame/GoddessOfVictoryNikke''.
78* ''Film/BatmanDeadEnd'' is a fan film about ComicBook/{{Batman}} meeting [[Franchise/AlienVsPredator a Xenomorph and a Predator]] while pursuing ComicBook/TheJoker in Gotham City.
79* ''Webcomic/ComicBookSNAFU'' is a MassiveMultiplayerCrossover featuring (among others) characters from Creator/MarvelComics, Creator/DCComics, Manga/FairyTail and...Anime/YuGiOh5ds.
80* ''Fanfic/CrasVivereParaBellum'' revolves around HitmanWithAHeart Franchise/JohnWick being reincarnated into the mostly idealistic ''Manga/MyHeroAcademia'' as [[ProneToTears Izuku]] [[ShrinkingViolet Midoriya]].
81* Announcements of [[Creator/{{Disney}} the Walt Disney Company]] buying Creator/MarvelComics and the ''Franchise/StarWars'' franchise gave birth to a lot of FanArt showing Mickey and Co. dressed as Marvel or ''Star Wars'' characters.
82* [[https://twitter.com/Jurassic_Live?t=DTHc5V74ybM5BmF7qwo4jg&s=09 Dinotracker]] has a series of fanart involving the girls of the idol series ''Franchise/LoveLive'' in the setting and roles of the ''Franchise/JurassicPark'' films.
83* Exaggerated in the fan video ''[[https://www.youtube.com/watch?v=82j_8I9Yi7k The Incredibles Get Sick!]]'', which is a crossover between ''Franchise/TheIncredibles'', ''WesternAnimation/{{Tangled}}'', ''WesternAnimation/{{Zootopia}}'' and ''WesternAnimation/DocMcStuffins''.
84* ''[[http://knapp-street.org/FeenMaggie/LASTheForce.html Laverne and Shirley Meet the Force]]'' is a crossover between ''Series/LaverneAndShirley'' and ''Franchise/StarWars''.
85* ''Fanfic/TheManyWorldsInterpretation'' is Creator/TerryPratchett's ''Literature/{{Discworld}}'' meets ''Series/TheBigBangTheory''. Magic meets science, a flat earth intrudes on the physics and cosmology of a spherical one, dysfunctional intellects clash in the context of a university full of egotists and oddballs...
86* ''Fanfic/MortalKombatVsTheOwlHouse'': A kids show like ''WesternAnimation/TheOwlHouse'' crossing over with a violent M-rated video game franchise like ''Franchise/MortalKombat'' would qualify as one.
87* From the mind of author Peter Guerin, we got ''Fanfic/TheMiserySenshiNeoZeroDoubleBlitzkriegDebacle'' and ''Fanfic/ReturnOfTheLawndaleMilitia'', which both involve ''WesternAnimation/{{Daria}}'' crossing over with ''Anime/SailorMoon'' in the former, and ''Manga/GunsmithCats'', ''Anime/RidingBean'' and ''Manga/HereIsGreenwood'' in the latter. An [[WhatCouldHaveBeen unproduced third instalment]] would’ve brought back Sailor Moon, along with ''WesternAnimation/TheRealGhostbusters'' and ''Manga/YoureUnderArrest''.
88* [[http://muzski.darkfolio.com/ Muzski]] created a series of ''Franchise/{{Tintin}}'' cover pastiches [[http://geektyrant.com/news/2012/6/11/the-adventures-of-tintin-and-the-horrific-world-of-hp-lovecr.html merging Tintin's universe with]] the Franchise/CthulhuMythos.
89* ''[[https://www.fanfiction.net/s/10890096/1/Ned-Flanders-in-Madagascar Ned Flanders in Madagascar]]'': Subverted. It appears to be a crossover between ''Franchise/{{Madagascar}}'' and ''WesternAnimation/TheSimpsons'', but it turns out that Marty was on drugs and tripped the whole thing.
90* ''Fanfic/NeonGenesisEvangeleMon'' is a crossover between ''Anime/NeonGenesisEvangelion'' and ''Franchise/{{Pokemon}}''. [[spoiler: It turns out to be an in-universe movie that the cast of the ''Pokemon'' anime are watching.]]
91* ''Old-Fashioned Remedies'' is an inappropriate ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfiction which features Boba Fett from ''Franchise/StarWars''.
92* Creator/PeterChimaera's ''[[Fanfic/PeterChimaerasDigimonTrilogy Digimon 3: Predator Vs Digimon]]'' is a TrollFic, which, like the title suggests, features a Franchise/{{Predator}} fighting a Franchise/{{Digimon}}. After their fight, they work together to unveil a sinister GovernmentConspiracy involving the FBI.
93* ''Fanfic/StarsAbove'', a crossover between ''Manga/LuckyStar'' and ''Franchise/MadokaMagica''... in which utter strangeness and impossibility of these two series crossing over is part of the plot.
94** By one of ''Stars Above's'' co-authors, there's also ''Fanfic/{{Respect}}'', a WhatIf story crossing over ''Madoka Magica'' and ''Anime/SmilePrettyCure''... and it's played for all the NightmareFuel possible.
95* ''Fanfic/TopHatsAndTigers'', a crossover between ComicStrip/CalvinAndHobbes and VideoGame/ProfessorLayton.
96* ''Fanfic/ToukenDanshiAndTheOrderOfThePhoenix'': It's ''Literature/HarryPotter'' meets ''VideoGame/ToukenRanbu''. What pushes it further still into this territory is the ''completely serious and unironic attitude'' the fic plays this wacky premise out.
97* ''Fanfic/UntilTheEndOfTime'' crosses over Anne Frank's ''Literature/TheDiaryOfAYoungGirl'' with ''Franchise/DragonBall''. It culminates in Goku taking down Hitler and marrying Anne.
98* ''[[https://my.w.tt/6Vg6fGMEsT Final Stand of Death]]'' has WebAnimation/DangerDolan and other random viewers watching what is clearly WesternAnimation/CelebrityDeathmatch FIC, with a group of [[TheDisembodied souls taking over]] new armor, i.e. Mecha, and tracking down the one who destroyed original bodies. Those in Script Form gives clues on who can it be, but who’ll be [[NoManOfWomanBorn The MacDuff to The MacBeth]] in the case.
99* ''[[https://archiveofourown.org/works/201650 All Good Truths]]'' is a ''Kingdom Hearts'' crossover where Xemnas and Xigbar travel to the world of ''Tailchaser's Song''. One is a Disney JRPG and the other is a fantasy adventure novel about cats.
100* Thanks to sharing a release date (and to the fact that they have ''nothing else'' in common otherwise, which made for an amusing juxtaposition), ''VideoGame/DoomEternal'' and ''VideoGame/AnimalCrossingNewHorizons'' received a number of pieces of crossover fanart featuring Doom Slayer and Isabelle hanging out together.
101* ''Fanfic/ZachIHateYou'' is a crossover between ''Webcomic/MiasWorld'' and Music/{{Tally Hall}}. It has lots of action, some [[UnusualEuphemism Unusual Euphemisms]], and a {{Random Events Plot}} that involves the [[TheMafia the Tally mafia]] and gangs. Defies logic on every level to the point where the author [[LampshadeHanging points it out frequently]].
102* ''Fanfic/InfinityTrainBlossomverse'' mixes ''[[Franchise/{{Pokemon}} Pokémon]]'' and ''[[WesternAnimation/InfinityTrain Infinity Train]]'', which is already rather strange, but then ''Fanfic/InfinityTrainBlossomingTrail'' Act 2 onwards adds, of all things, '''''[[Franchise/SilentHill Silent Hill]]''''' to the mix.
103** The prequel story ''Fanfic/InfinityTrainKnightOfTheOrangeLily'' is also a ''Pokémon'' and ''Infinity Train'' crossover with ''Anime/YuGiohVRAINS'' (albeit the latter is justified as the author has been shown to have a fondness for Specter) and wrestling (Paul London is in his ''Wrestling/LuchaUnderground'' incarnation).
104** Finally, ''Fanfic/InfinityTrainVoyageOfWisteria'' has a storyline where the Apex kids have to be dragged into the [[WesternAnimation/HazbinHotel The Hazbin Car.]]
105* ''WesternAnimation/InfinityTrain'':
106** ''Fanfic/InfinityTrainBoilingPoint'' mixes ''Infinity Train'' with ''[[WesternAnimation/TheOwlHouse The Owl House]]'', which is already kinda weird, since they're at opposite sides of the genre spectrum (The former is a horror fantasy comedy, the latter is a supernatural sci-fi anthology). Then you add [[spoiler: ''Fanfic/InfinityTrainBlossomingTrail'']] into the mix, and you know this trope's in play.
107** ''Fanfic/InfinityTrainStarFinder'' crosses ''Infinity Train'' and ''WesternAnimation/TheLoudHouse'', two series which are ''way apart'' in tone and genre (mature supernatural sci-fi and slice-of-life comedy, respectively).
108** While ''Fanfic/InfinityTrainSeekerOfCrocus'' is a re-telling of ''Blossoming Trail'', one of its side stories is one of the most bonkers crossovers of them all in the universe. ''Rey Mysterio vs the Cosmos'' is set in the world of a wrestling cartoon ''WesternAnimation/ReyMysterioVersusLaOscuridad'' combined with ''Lucha Underground'' and ''Series/KikaiSentaiZenkaiger'' with ''Pokémon'' and ''Infinity Train'' being in the background.
109* The first few chapters of ''Fanfic/OSMUFanfictionFriction'' has the Mobile Unit visiting Metropolis in order to have an adventure worthy of making into a fanfic form, mixing ''Series/OddSquad'' with ''ComicBook/{{Superman}}''. This is a staple trope of the author's works, as he has other fanfics that mix ''Odd Squad'' with other media like ''Series/{{Bewitched}}'' and ''Franchise/ScoobyDoo''.
110* [[https://i.imgflip.com/71c7k9.jpg So there's a picture of]] Mami Miura from ''Manga/TheIslandOfGiantInsects'' being placed in ''[[Literature/NineteenEightyFour 1984]]'' by George Orwell. If Mami was terrified of gigantic, man-killing bugs, imagine how horrified for her to be in a dystopian dictatorship that is Oceania? We bet she would be utterly horror-stricken to deal with the Big Brother's totalitarian control (to top it all, she's an IdolSinger in the source material).
111** That said, its likely Mami would be able fight the Ingsoc party, if the manga's sequel is any intention, though the victory would be near-impossible to achieve, due to the Thought Police.
112** It is also said that the hypothetical game would be HGame, again wouldn't be far too off for Mami's side of the crossover (only instead of {{Ecchi}} would be fully fledged {{hentai}} one). Perhaps Mami's sexual tactics would be much more vigorous, forceful and aggressive than she did with Matsuoka in the source material (which would give a devastating blow to the world she is placed in, since pornography in 1984 is either bad, forbidden or straight up FanDisservice)[[note]] Ironically, it is depicted to be a Platform/SuperNintendoEntertainmentSystem game, something Nintendo wouldn't allow at least until late 90s, unless if it's a bootleg.[[/note]].
113* ''Fanfic/YuGiOh5DsaLive'' is a crossover between [[Anime/YuGiOh5Ds an anime where card games are played on motorcycles]] and [[VideoGame/LiveALive a game that spans across time and space where the heroes fight off a villain who has the same name for some odd reason]], in which the heroes of the latter are stuck having to deal with the Dark Signers after the anime goes off the rails.
114[[/folder]]
115
116[[folder:Films -- Animation]]
117* The trailers for ''WesternAnimation/LiloAndStitch'' mix between the original film, ''WesternAnimation/BeautyAndTheBeast'', ''WesternAnimation/{{Aladdin}}'', ''WesternAnimation/{{The Little Mermaid|1989}}'' and ''WesternAnimation/{{The Lion King|1994}}''. They show Stitch interfering with the other movies' {{Signature Scene}}s before he gets scolded.
118* ''WesternAnimation/TheLegoMovie'' mixes several LEGO licensed universes. While ComicBook/{{Batman}} is a major character, there are many [[TheCameo cameos]] and {{One Scene Wonder}}s involving Creator/DCComics characters (ComicBook/{{Superman}}, ComicBook/GreenLantern, ComicBook/WonderWoman, etc), [[Franchise/HarryPotter Albus Dumbledore]], [[Franchise/StarWars Han Solo, Chewbacca, C3PO and Lando Calrissian]], [[Film/TheLordOfTheRings Gandalf the Grey]], [[Franchise/TeenageMutantNinjaTurtles Michelangelo]], etc. It is a rare example when the crossovers receive an InUniverse justification: TheReveal tells that [[spoiler:the animated part of the movie actually represents the imagination of a boy playing with his father's own LEGO collection.]]
119* ''WesternAnimation/TomAndJerryWillyWonkaAndTheChocolateFactory'' is proof that sometimes, [[Administrivia/TropesAreTools Tropes Are Not Good]]. The ''WesternAnimation/TomAndJerry'' DirectToVideo film series has been going in this direction for a while now, working the classic cartoon {{slapstick}} duo into {{Twice Told Tale}}s with the likes of Franchise/SherlockHolmes, Myth/RobinHood, ''Film/TheWizardOfOz'', and ''WesternAnimation/JonnyQuest'', [[FranchiseOriginalSin but those were seen as harmless and went under the radar of various reasons]].[[note]]Franchise/SherlockHolmes and Myth/RobinHood are both deep in the PublicDomain. ''Jonny Quest'' is, like ''Tom & Jerry'', a Creator/HannaBarbera original, and the company has always been notoriously crossover-happy. ''The Wizard of Oz'' was where things started to get iffy, but the film's longevity and the fact that the two originated under Creator/{{MGM}} gave the crossover ''some'' precedent.[[/note]] Crossing over with ''Film/WillyWonkaAndTheChocolateFactory'', however, [[AudienceAlienatingPremise had no such benefit,]] resulting in fandom snark, coming from the idea of ''Tom & Jerry'' being needlessly shoehorned into classic cinema.
120* ''WesternAnimation/HappyHalloweenScoobyDoo'' features Mystery Inc. meeting [[Characters/BatmanTheScarecrow the Scarecrow]]-- only in a first for a crossover involving ''ComicBook/{{Batman}}'' characters, Bruce Wayne himself isn't around to help, but instead said help is from Series/{{Bill Nye|TheScienceGuy}} and Creator/{{Elvira|MistressOfTheDark}}. [[spoiler:And Crane isn't even the main villain, but a RedHerring who happens to be an Elvira fanboy.]]
121* ''WesternAnimation/DCShowcaseSgtRock'' sees the titular ComicBook/SgtRock working with the Creature Commandos.
122[[/folder]]
123
124[[folder:Films -- Live-Action]]
125* ''Crazy Safari'', a crossover between ''Film/TheGodsMustBeCrazy'', a zany South African satire about the lifestyle differences between an isolated African tribe and some bumbling Westerners... and ''Film/MrVampire'', a supernatural horror-comedy about a killer ChineseVampire.
126* ''Film/Venom2018'' and ''VideoGame/Persona5'' had a collaboration for the film's Japanese release.
127* ''Film/{{Ted}}'' and ''VisualNovel/DanganronpaTriggerHappyHavoc'' had a collaboration due to the film and TheAnimeOfTheGame getting [=DVD=] releases around the same time. Other than that, the only thing the two have in common are talking teddy bears.
128[[/folder]]
129
130[[folder:Literature]]
131* The ''Literature/MrMen'' series of children's picture books launched a {{Spinoff}} line in 2017 [[http://io9.gizmodo.com/theres-going-to-be-a-whole-line-of-doctor-who-themed-mr-1787660174 crossing over its art and storytelling style]] with the characters and typical plots of ''Series/DoctorWho'', the live-action ScienceFiction TV franchise. Also counts as a FakeCrossover, but with real tie-in merchandise!
132** Another {{Spinoff}} line was launched in 2019, this time crossing over the ''Mr. Men'' art and storytelling style [[https://www.inquisitr.com/5415504/the-spice-girls-launch-their-own-childrens-book-with-mr-men-and-little-miss/ with the adventures of]] the Music/SpiceGirls.
133* Paul Kline's ''Sherlock Holmes and the Servants of Hell'' crosses the [[Literature/SherlockHolmes great detective]] over with ''Franchise/{{Hellraiser}}''.
134** Holmes gets hit with this a lot, since he's both immediately recognizable and [[PublicDomainCharacter free for anyone to use]]. He's especially popular in licensed novels, for some reason; a good example is his appearance in the Victorian segments of the ''Franchise/FinalDestination'' book ''Literature/DestinationZero''.
135[[/folder]]
136
137[[folder:Live-Action TV]]
138* The Halloween crossover between ''{{Series/Bones}}'' and ''Series/SleepyHollow''. ''Bones'' is largely reality based forensic science, albeit with a little ArtisticLicense and any paranormal stuff is MaybeMagicMaybeMundane territory, while ''Sleepy Hollow'' was a fantasy series inspired by the book, that was heavily based in the supernatural. The ''Bones'' was pretty mundane aside from Ichabod trying to find a convincing explanation for Brennan of why his handwriting perfectly matched a letter to George Washington written in the 1700s. The ''Sleepy Hollow'' half had the remains that had been retrieved from the lab re-animate and Ichabod and Abby had to fight the guy while Booth and Brennan conveniently missed seeing anything that would shake up their characterizations, particularly Brennan’s.
139* In ''Series/BoyMeetsWorld'', professional wrestler [[Wrestling/BigVanVader Vader]] appears as the father of Frankie and Herman. His name on the series is Francis Albert Leslie 'Frankie' Stechino, Sr., while the RealLife Vader is Leon Allen White.
140* ''Series/TheDrewCareyShow'' is a standard comedy show about office life. So when no one else than ''WesternAnimation/DaffyDuck'' makes a guest appearance in the beginning of a season 3 episode, it's a very surprising choice as a literal cartoon duck doesn't really fit in the usual sitcom setting.
141* Scott Bakula had a season or so long arc guest starring on ''Series/MurphyBrown'' as Murphy's love interest, and they almost got married. In Bakula's last episode, he leaves the newsroom bullpen via elevator and you see him [[Series/QuantumLeap glowing blue as if he's leaping]].
142* ''Series/OddSquad'': A Creator/{{CBBC}} promo for Season 2 crosses the show over with, of all shows, ''Series/StrangerThings''. Perhaps unsurprisingly, the promo has never been released outside of the UK, only being seen on CBBC's website, and has gotten no recognition by Creator/{{Netflix}}.
143* ''Series/SanfordAndSon''. A crossover with ''Series/HawaiiFiveO'' is heavily invoked in "The Hawaiian Connection" trilogy. While Fred and Lamont get caught up in a diamond smuggling ring that's being investigated by the actual Five-O, references to Steve [=McGarrett=] (famous hair and all) are made throughout, implying that in-Sanford-universe, [=McGarrett=] actually works for the actual Five-O.
144* A ''Series/SaturdayNightLive'' sketch from 1999 involved a humorous crossover between ''{{Series/Seinfeld}}'' and ''{{Series/Oz}}'', in which Creator/JerrySeinfeld is incarcerated at Oswald State Correctional Facility, where he [[SeinfeldianConversation casually chats]] about prison life with Tobias Beecher, Vernon Schillinger, Ryan O'Reilly, and Augustus Hill.
145** In 2023, the year of release of both Creator/{{HBO}}'s ''Series/{{The Last of Us|2023}}'' and ''WesternAnimation/TheSuperMarioBrosMovie'', SNL did a crossover between ''[[Franchise/SuperMarioBros Mario]] [[VideoGame/MarioKart Kart]]'' and ''VideoGame/TheLastOfUs'', starring the HBO series' Creator/PedroPascal himself.
146* ''Series/StarTrekStrangeNewWorlds'' crosses over with ''WesternAnimation/StarTrekLowerDecks'' in "[[Recap/StarTrekStrangeNewWorldsS2E07ThoseOldScientists Those Old Scientists]]". While both shows are in the Franchise/StarTrek Universe, one is an old school, earnest live action show and the other is an aggressively silly animated show. The episode sees two animated characters get sucked into the live action show and played by the actors who voice them.
147* The ''Series/{{Supernatural}}'' episode "[[Recap/SupernaturalS13E16ScoobyNatural ScoobyNatural]]" crossed over with an old episode of ''WesternAnimation/ScoobyDooWhereAreYou''. While both series share the common ground of featuring {{paranormal investigat|ion}}ors, ''Franchise/ScoobyDoo'' is a kids' show and ''Supernatural'' '''really''' isn't. In fact, some of the conflict comes from the Winchesters trying to shield Mystery Inc. from the nastier stuff that the latter aren't equipped to deal with.
148* In the ''Series/TheXFiles'' episode "X-Cops" the producers of an episode of ''Series/{{COPS}}'' run into Mulder & Scully while filming one of their episodes and end up following them as they investigate one of their cases.

151[[folder:Music]]
152* At one of the stranger points during the 60s, Music/TheMonkees and Music/JimiHendrix toured together. Apparently, the thinking behind this was that the Monkees were trying to increase their cool cred, while Hendrix was trying to get more mainstream popularity. Needless to say, the tour did not go well, mainly because the audiences were primarily made up of screaming young girls.
153* Music/BingCrosby and Music/DavidBowie [[https://www.youtube.com/watch?v=n9kfdEyV3RQ singing Christmas music together]]. Could there be two more dissimilar musicians in any universe? For bonus points, the cheesy banter of the christmas special quickly gives way to a pair of master musicians creating a beautiful blending of old and new sounds.
154* [[https://rave.dj/ Rave.DJ]] allows the user to input any two Website/YouTube videos of reasonable length to create a mashup, allowing a Weird Crossover between any two songs. Do you want to combine [[Music/{{Communications}} Rotary Dial]] and [[Music/MarinaDiamandis Bubblegum Bitch]]? [[https://on.soundcloud.com/BiyuCeuuRqBDeu9r5 Not only has it been done,]] but it works surprisingly well.
155[[/folder]]
156
157[[folder:Music Videos]]
158* The music video to Music/FallOutBoy's "[[https://www.youtube.com/watch?v=eCV2h1uHx3o The Carpal Tunnel Of Love]]" is a crossover with ''WebAnimation/HappyTreeFriends'', a cartoon where the entire joke is adorable animal characters dying in various gorey ways. The music video stays true to this theme by featuring the characters (including FunnyAnimal versions of the band) all dying in true ''HTF'' fashion.
159[[/folder]]
160
161[[folder:Podcasts]]
162* This is the entire premise of ''Podcast/InterstitialActualPlay'', which takes the initial idea of ''Franchise/KingdomHearts'' (''Final Fantasy'' and ''Disney'' characters crossing paths to save the world) and ramps it beyond what one could possibly imagine.
163** The first season restricted items to only the aforementioned two domains but still managed to create a plot involving [[VideoGame/FinalFantasyTacticsAdvance Marche Radiuju]], a slacker version of [[WesternAnimation/AGoofyMovie Roxanne]], and OC Edith teaming up with Series/CrissAngelMindfreak to stop the Organization XIII. They travel through the worlds of ''Film/HighSchoolMusical'', ''Series/PowerRangersRPM'', ''Franchise/SonicTheHedgehog'', and ''Series/{{Lost}}''--and the last of which is where things get ''real'' weird.
164** ''A Touch of Evil'' is the first of the one-shots in which there are no longer any limits. [[WesternAnimation/KimPossible Shego]] and [[Anime/PuellaMagiMadokaMagica Homura Akemi]] fight Kim Possible and keyblade master Fred Andrews in Series/{{Riverdale}} in order to kidnap Archie.
165** ''Reality and Other Falsehoods'': [[VideoGame/TonyHawksProSkater Tony Hawk]], Creator/OwenWilson, and [[VideoGame/{{Undertale}} Papyrus]] travel to the world of [[Franchise/TheElderScrolls Tamriel]] to fight [[spoiler: [[Anime/DragonBallZ Cell]]]].
166** ''A Rush of Sugar to the Head'': [[WesternAnimation/AvatarTheLastAirbender Azula]], [[WebAnimation/{{RWBY}} Cinder Fall]], and [[Franchise/SuperMarioBros Morton Koopa]] travel to [[WesternAnimation/WreckItRalph Sugar Rush]] to help King Candy destroy Vanellope.
167** ''Lonely Souls'': [[Anime/DigimonTamers Calumon]] and Bright Eyes (from the "Total Eclipse of the Heart" music video) travel to Series/TwinPeaks to free [[VideoGame/AnotherWorld Mycaruba]] and [[Music/DangerDaysTheTrueLivesOfTheFabulousKilljoys Party Poison]].
168** ''2 Family 2 Furious'': UsefulNotes/AmeliaEarhart, [[Film/TheFastAndTheFurious Brian o'Connor]], and [[Manga/JoJosBizarreAdventure Caesar Zepelli]] must fight against Lucky Lindy and Wrestling/BrayWyatt to save Wrestling/MattHardy and Webcomic/ProblemSleuth from being destroyed.
169[[/folder]]
170
171[[folder:Roleplay]]
172* ''Roleplay/InsaneCafeSeries'' has [[Series/KamenRiderKiva Wataru]], [[Roleplay/DarwinsSoldiers Dr. Zanasiu]], Franchise/ScoobyDoo, [[Franchise/{{Digimon}} Guilmon]], Franchise/SpyroTheDragon, and [[WesternAnimation/LiloAndStitch Nani]] as main characters... and that's only the tip of the iceberg!
173* ''Roleplay/NoPixel'' has included, among others, [[Series/TheWalkingDead Carl]] [[CaptainErsatz Crimes]], [[WesternAnimation/GoDiegoGo Diego]], [[VideoGame/AnimalCrossing Tom Nook]], [[VideoGame/Cyberpunk2077 Johnny Silverhand]], and [[WesternAnimation/SpongeBobSquarepants Plankton]] all co-existing alongside fairly "normal" original characters and [[VileVillainSaccharineShow realistically monstrous characters]].
174[[/folder]]
175
176[[folder:Pro Wrestling]]
177* In 1999 SFX Motorsports began building Wrestling/{{WCW}} themed monster trucks. Chad Fortune of The Pit Crew TagTeam and Wrestling/{{Madusa}} were the only wrestlers who drove their own trucks and since WCW buried both of them, they became more famous as monster truck drivers than pro wrestlers, especially Fortune, who retired from wrestling completely. Madusa still appeared on the shows of Wrestling/WorldWonderRingSTARDOM, Wrestling/NationalWrestlingAlliance, RISE and such, even if her driving commitments prevented her from wrestling on them.
178* The year was 1990. Wrestling/{{WCW}} aired the pay-per-view Capitol Combat, which involved, alongside some genuinely excellent matches, Wrestling/{{Sting}} being rescued from the Four Horsemen by... ''Franchise/{{Robocop}}''? Then later in 1998, [[Franchise/ChildsPlay Chucky]] would make an appearance to plug his latest movie.
179* Quite a few reality shows have crossed over with pro wrestling shows. ''Dana White: Lookin' For A Fight'' going with UFC and or Wrestling/JerryLawler's Memphis Wrestling isn't so weird. ''Series/{{Jackass}}''(FakeCrossover with Wrestling/{{TNA}}), ''Series/JerseyShore''(actual crossover'''s''' with TNA and Wrestling/JuggaloChampionshipWrestling), ''Series/{{Survivor}}''(With Wrestling/ImpactWrestling and Wrestling/RingOfHonor only being its most notable examples) are very weird. InUniverse, the Dave Prazak and Lenny Leonard were embarrassed to see Johnny Fairplay in the ring.
180* While Wrestling/KaijuBigBattel is technically staying in the same genre when it crosses over with other pro wrestling promotions, it doesn't happen very often for very good reasons. Even when those wrestlers come from other "weird" promotions like Wrestling/ProWrestlingZero1, Wrestling/{{Chikara}} or Wrestling/DramaticDreamTeam(for escalating levels of weirdness) they still tend to stick out like sore thumbs, to say nothing of the mostly regular wrestlers working for the WWN family promotions.
181[[/folder]]
182
183[[folder:Tabletop Games]]
184* ''TabletopGame/InterstitialOurHeartsIntertwined'' is designed to facilitate these, as one can imagine from the actual play described in the podcasts folder above. The mission statement is to play as existing characters, throw them together, and take them to worlds contradictory to their own.
185[[/folder]]
186
187[[folder:Toys]]
188* Companies behind ShoddyKnockoffProduct action figures frequently package together characters from different unrelated entertainment brands, resulting in very weird team ups. A good example is the [[http://knowyourmeme.com/photos/530109-bootleg-knock-off Sense of Right Alliance]], which posits a teamup between ''Franchise/{{Cars}}'', ''ComicBook/{{Batman}}'', ''ComicBook/FantasticFour'', ''Franchise/TheIncredibles'', ''Franchise/PowerRangers'', ''Franchise/{{Shrek}}'', ''ComicBook/SpiderMan'', and ''ComicBook/{{Superman}}''.
189* Which is not to say that official products don't indulge in some weird combinations themselves, such as ''Franchise/{{Transformers}} x [[Anime/NeonGenesisEvangelion Evangelion]]''. [[https://tfwiki.net/wiki/Evangelion See TFwiki for more info]]
190* ''Franchise/{{Transformers}}'' especially loves to do these sorts of things. Brought to a head with the ''Transformers Collaborative'' line of toys, which includes both fairly reasonable crossovers with the likes of ''Franchise/BackToTheFuture'' or the ''ComicBook/XMen'', and some that boggle the mind, like... ''Franchise/JurassicPark'', ''Film/TopGun'', and ''[[Franchise/UniversalHorror Dracula]]''?
191[[/folder]]
192
193[[folder:Video Games]]
194!!!Commercial VideoGames
195* ''VideoGame/BlackDesertOnline'', a fantasy MMORPG, has had some relatively normal collaborations with the dark fantasy manga ''Manga/{{Berserk}}'' and short-lived fantasy streaming series ''Series/Cursed2020''. In 2021, coming straight out of left field is a collaboration with Bugatti, (yes, ''that'' Bugatti that makes [[CoolCar exotic cars]]) complete with bright blue Bugatti "B"-emblazoned costumes for your character and its CoolHorse. One has to imagine how many MMO players the cross-promotion enticed into shelling out at minimum $3 million USD for their next automobile purchase.
196* ''VideoGame/BlazBlueCrossTagBattle'', Creator/ArcSystemWorks trying its hand at a MascotFighter, came out of nowhere by combining ''Franchise/BlazBlue'' (a series thought to be on hiatus after its GrandFinale), ''VideoGame/Persona4Arena'' (an era thought to be finished in the wake of ''VideoGame/Persona5''), ''VideoGame/UnderNightInBirth'' (a game that wasn't even very popular in Japan, and is extremely obscure outside of it), and finally, ''WebAnimation/{{RWBY}}'' (which made waves as an American-made {{Animesque}} WebAnimation series), in its roster. A fifth series, ''VideoGame/ArcanaHeart'', which features Moe-styled female characters, was added later on. In the 2.0 update, ''VideoGame/SenranKagura'' and ''VideoGame/AkatsukiBlitzkampf'' joined the fun as well.
197* ''VideoGame/{{Broforce}}'' stars a who's who for all sorts of action movies and TV shows... sorta. It's {{Downplayed|Trope}} in that they're all ''technically'' {{Lawyer Friendly Cameo}}s, but the copious RuleOfCool quotient keeps players from being too hung up on that detail.
198* VideoGame/CapcomVs may be the TropeCodifier within video games. The flagship series ''VideoGame/MarvelVsCapcom'' may be a big name now, but at the time, the sight of [[Franchise/StreetFighter a bunch of martial artists]] [[VideoGame/XMenVsStreetFighter slugging it out]] with the ''ComicBook/XMen'' had to raise a few eyebrows and created some playground and online debates. Creator/{{Capcom}} challenging {{anime}} giant Creator/TatsunokoProduction in ''VideoGame/TatsunokoVsCapcom'' is another crazy example.
199* ''VideoGame/CookieRunKingdom'' is a building sim RPG based off of ''VideoGame/CookieRun'', an EndlessRunner about living gingerbread men. While the crossover with Disney made sense (as they're all about sweets, wonder, and childhood innocence) the second crossover with ''Music/{{BTS}}'' doesn't as it depicts all seven members of Korea's number one boy band together (with all members playable ''and'' voiced!) as adorable cookies, which is not even counting the fact that BTS are ''real-life celebrities'' crossing over.
200* ''VideoGame/CrystalCrisis'' is a puzzle game containing characters from a widely disparate group of franchises. It includes several indie game characters like [[VideoGame/CaveStory Quote and Curly Brace]], [[VideoGame/OneThousandAndOneSpikes Aban Hawkins]]... [[VideoGame/TheBindingOfIsaac Isaac]], ''Manga/AstroBoy,'' and Johnny Turbo, the defunct [=TurboGrafx=] mascot!
201* One type of item in ''VideoGame/Dota2'' replaces the lines of the game's default announcer when equipped, and these are sometimes crossover items. These go from the expected (Dr. Kleiner from ''VideoGame/HalfLife'', [=GLaDOS=] from ''VideoGame/{{Portal}}'') to the unexpected (Adam Jensen from ''VideoGame/DeusExMankindDivided'', Mister Handy from ''VideoGame/Fallout4'', Wayne June from ''VideoGame/DarkestDungeon'', Rucks from ''VideoGame/{{Bastion}}'', the Narrator from ''VideoGame/{{Trine}}'', the Narrator from ''VideoGame/TheStanleyParable'', and WesternAnimation/RickAndMorty). There's also a HUD theme item based on ''Portal'' and a loading screen item based on ''VideoGame/FinalFantasyType0''.
202* ''VideoGame/DrawnToLife: WesternAnimation/SpongeBobSquarePants Edition''. You take the concept of ''Drawn to Life'' and its aspect of drawing pretty much anything and having it appear in the game, and then you apply that to the world of [=SpongeBob=]. At least this still works because of [=DoodleBob=].
203** There's also ''[=SpongeBob=] VideoGame/DinerDash'', though this one is less weird because of [=SpongeBob=]'s link through cooking with the Krusty Krab and the Krabby Patty.
204* ''VideoGame/DreamMixTVWorldFighters'' is described as "the only crossover where every character is an UnexpectedCharacter", and for good reason. It's a MascotFighter featuring Creator/{{Konami}}, Creator/HudsonSoft (before the latter's merger into the former) and Creator/{{Takara}} (the overseas equivalent to Creator/{{Hasbro}}), which results in the likes of [[Franchise/{{Castlevania}} Simon Belmont]], [[VideoGame/MetalGear Solid Snake]], VideoGame/{{Bomberman}}, [[Franchise/{{Transformers}} Optimus Prime]], [[Anime/BakutenShootBeyblade Tyson Granger]], Toys/LiccaChan, and so on joining to battle.
205* One "official" mod for ''VideoGame/TheElderScrollsVSkyrim'' (official in the sense that it was written by Creator/{{Bethesda}} and Creator/{{Valve}}, albeit mostly as a joke) has the Space Core from ''VideoGame/Portal2'' crash-land outside Whiterun.
206* ''Family Guy: The Quest For Stuff'': Various events have seen the cast of ''WesternAnimation/FamilyGuy'' joining forces with [[Series/StarTrekTheNextGeneration the crew of]] the ''[[Franchise/StarTrek Enterprise]]'', the ComicBook/JusticeLeague, the Film/{{Power Rangers|2017}}, the Film/MenInBlack, and many more. [[http://family-guy-the-quest-for-stuff.wikia.com/wiki/Characters A mostly up-to-date list is available here.]]
207* ''Franchise/FinalFantasy'':
208** In ''VideoGame/FinalFantasyAllTheBravest'', a mashup of ''Final Fantasy'' locations, bosses, monsters and characters co-exist in the same setting without much context as to why. ''VideoGame/FinalFantasyRecordKeeper'' attempts to justify this with an initial ExcusePlot involving paintings, which has been expanding significantly over the years.
209** ''VideoGame/MarioSportsMix'' and ''VideoGame/MarioHoops3On3'' feature characters from ''Final Fantasy'' and ''VideoGame/DragonQuest'' as unlockable characters. Needless to say, it's rather odd to see characters like the Slime, Black Mage and Moogle play traditional sports [[VideoGame/FinalFantasyX (emphasis on traditional)]] against Mario and friends. Thankfully, most of the characters got redesigned to fit more into the Mario universe.
210** ''VideoGame/FinalFantasyXIV'' and ''VideoGame/FallGuys''. Yes, really. This went both ways by adding a ''Final Fantasy'' themed battle pass to ''Fall Guys''.
211** A free piece of DownloadableContent for ''VideoGame/FinalFantasyXV'' [[https://www.gamespot.com/articles/free-final-fantasy-xv-dlc-adding-assassins-creed-e/1100-6452834/ mashes up]] the fictional world of Eos with the history-based ''Franchise/AssassinsCreed'' series.
212** ''VideoGame/FinalFantasyBraveExvius'' has an arm long list of crossovers, from the most obvious choices (''Franchise/KingdomHearts'', ''Franchise/DragonQuest'', ''VideoGame/WorldOfMana'') to the somewhat unexpected but that still make sense (''VideoGame/{{Xenogears}}'', ''VideoGame/NierAutomata'', ''VideoGame/OctopathTraveler'', ''VideoGame/ValkyrieProfile'', ''VideoGame/StarOceanIntegrityAndFaithlessness'', ''VideoGame/ChronoCross'', ''VideoGame/ParasiteEve''), the ones that happened because Creator/SquareEnix is somehow involved as either the developer or publisher (''VideoGame/DeusExMankindDivided'', ''Franchise/TombRaider'', ''VideoGame/JustCause3''), to non-game properties that still involve the company (''Manga/FullmetalAlchemist'') to the ones that came out of the blue (Music/KatyPerry, Music/ArianaGrande, Creator/AddisonRae).
213*** ''VideoGame/WarOfTheVisionsFinalFantasyBraveExvius'', by contrast, doesn't go too overboard with its crossovers (except for Addison Rae), but still ended up receiving one with ''VideoGame/Persona5''.
214* In recent years ''VideoGame/{{Fortnite}}'' has become the master of this type of crossover. While most collaborations are with immensely popular brands such as Creator/{{Marvel|Comics}}, Creator/DCComics, ''Franchise/{{Naruto}}'', etc., crossover-magnets like ''Franchise/StreetFighter'' and ''Franchise/{{Predator}}'', or tie-ins to [[Franchise/JohnWick contemporary]] [[Film/Dune2021 big]] [[Film/FreeGuy name]] [[Film/SpaceJamANewLegacy releases]] [[UnCanceled and]] [[{{WesternAnimation/Futurama}} revivals]], some of them come ''completely'' out of left field, such as [[Literature/MistbornTheOriginalTrilogy Kelsier]] and Series/ElChapulinColorado.
215* The normally semi-realistic ''VideoGame/{{Forza}} Horizon 3'' goes a bit crazy with its cross-promotional second DownloadableContent expansion and includes a set of islands full of twisting and looping Toys/HotWheels stunt tracks, as well as some life-sized, driveable Hot Wheels cars.
216** ''Forza Horizon 4'' also goes this route, making its second expansion Franchise/{{LEGO}}-themed.
217* ''VideoGame/FunkoPopBlitz'', being based on the [[Toys/FunkoPop multi-franchise toyline of the same name]], features a variety of pop culture characters as playable characters, often leading into weird combinations, from ''[[Franchise/UniversalHorror Universal Studio Monsters]]'' to ''UsefulNotes/GeneralMills'' cereal mascots to the ''Franchise/CareBears''. And they all can appear on the same game boards together!
218** The same applies to the board game ''Funkoverse''. Most ''Funkoverse'' sets revolved around various sci-fi or fantasy franchises like ''ComicBook/{{Batman}}'', ''Franchise/HarryPotter'', ''Franchise/JurassicPark'', and ''Series/GameOfThrones''; but then there were a few featuring things like ''Anime/{{Aggretsuko}}'' and even ''Series/TheGoldenGirls''.
219* ''VideoGame/GenshinImpact'' once had a crossover with ''VideoGame/HorizonZeroDawn''. While both are [[WideOpenSandbox Open-World]] games, one is a [[Creator/MiHoYo Chinese]] Fantasy {{Gacha Game|s}}, while the other is a [[Creator/GuerrillaGames Amsterdam]] ScienceFiction FuturePrimitive with {{Humongous|Mecha}} AnimalMecha as wildlife.
220* ''VideoGame/HarvestMoon'':
221** ''Harvest Moon'' is a farm simulator with heavy life sim elements. ''VideoGame/PopoloCrois'' is a JRPG series. Naturally they received a crossover -- though it's more ''[=PopoloCrois=]'' with a ''Harvest Moon'' edge -- named ''Return to [=PopoloCrois=]: A Story of Seasons Fairytale''. It's quite different from the normal ''Harvest Moon'', being a bit more like sister series ''VideoGame/RuneFactory'' but not featuring the marriage system signature of either series (as the protagonist is a KidHero).
222** ''VideoGame/DoraemonStoryOfSeasons'' is a ''VideoGame/HarvestMoon'' title featuring ''Manga/{{Doraemon}}'' characters.
223* ''VideoGame/{{IMGCM}}'': The collaboration event with ''Manga/TheQuintessentialQuintuplets'' is quite surprising, as ''The Quintessential Quintuplets'' is a casual light-hearted RomanticComedy about a tutor with his quintuplet students, while ''I=MGCM'' is an {{Urban|Fantasy}} ScienceFantasy about DemonSlaying {{magical girl warrior}}s. It's got lots of FanService, and some DarkerAndEdgier moments that edge into MagicalGirlGenreDeconstruction. When the story begins, the quintuplets are in Kamisaman's [[AnotherDimension other White Room]], communicating with Omnis and his heroines through the computer in the quintuplet's White Room.
224* On its most basic level ''Franchise/KingdomHearts'' is essentially "''Creator/{{Disney}}'' meets ''VideoGame/FinalFantasy''". In reality the ''Final Fantasy'' characters are essentially cameos loosely based on their original characters, while the main cast is a series of ''[=FF=]''-esque OriginalGeneration characters. There are also oddball crossovers such as WesternAnimation/DonaldDuck interacting with the cast of ''Film/{{Tron}}''. All of this is wrapped up around a story involving the OriginalGeneration which is infamous for being confusing (and before the [=PS4=] [[CompilationRerelease collections]], hard to keep up with thanks to initially coming out of wildly different platforms and ''story details'' often being locked to [[NoExportForYou certain international releases]]), and much darker than your average Disney cartoon.
225* ''VideoGame/TheKingOfFightersAllStar'', a mobile BeatEmUp, did a crossover with Wrestling/{{WWE}} in 2020 that featured characters like [[Wrestling/DwayneJohnson The Rock]] and Wrestling/TheUndertaker as playable characters.
226* ''VideoGame/LegoDimensions'' takes ''The LEGO Movie's'' crossover concept and ramps it up. The game's story mode alone has ComicBook/{{Batman}}, [[Film/TheLordOfTheRings Gandalf the Grey]], and [[WesternAnimation/TheLegoMovie Wyldstyle]] visiting, among other things, [[Film/TheWizardOfOz Munchkinland]], [[WesternAnimation/TheSimpsons Springfield]], [[Film/BackToTheFuturePartIII 1885 Hill Valley]], and [[VideoGame/Portal2 Aperture Science]]. Even more franchises were added through updates for the next two years.
227* ''VideoGame/MetalGearSolid3SnakeEater'' featured a bonus minigame where Solid Snake is assigned capture a bunch of escaped monkeys from the ''VideoGame/ApeEscape'' series. In turn, ''Ape Escape 3'' featured a bonus mini-game where the player controls a monkey named Pipo Snake who must rescue Solid Snake.
228* ''VideoGame/NicktoonsMLB'': A baseball video game starring various Creator/{{Nickelodeon}} characters? Not bad. Adding RealLife UsefulNotes/MajorLeagueBaseball players into the mix? Now, that's crazy!
229* ''VideoGame/PAYDAY2'' had a crossover with ''VideoGame/GoatSimulator'' of all things. This went both ways by also adding a ''PAYDAY 2'' based DLC to ''Goat Simulator''.
230** The fact that Ethan and Hila of {{WebVideo/h3h3Productions}} are in the PAYDAY universe [[AsHimself as themselves]] is also worth mentioning.
231* The Fun Farm level of ''VideoGame/PizzaTower'' includes VideoGame/MortTheChicken as a "special guest". For some reason. What's even weirder is the way this character even appeared in the game: the creators of ''Pizza Tower'' simply asked for permission to add Mort the Chicken to the game, and their response was a "sure, why not?".
232* ''VideoGame/PokemonConquest'' is a crossover between ''Franchise/{{Pokemon}}'', a very [[LighterAndSofter light and idealistic]], ultra-popular {{Mons}} series, and ''VideoGame/NobunagasAmbition'', a real-time strategy game about Sengoku-era Japan which is obscure outside of its own country. Turns out, the CEO of the Pokémon Company had been a big fan of the ''Nobunaga's Ambition'' series, and in turn the CEO of Creator/KoeiTecmo had been a big fan of the ''Pokémon'' series, which is how this even happened in the first place.
233* ''VideoGame/PowerWashSimulator'' sure is taking you to places you wouldn't expect to go clean up stuff. You got [[Franchise/TombRaider Croft Manor]], [[VideoGame/FinalFantasyVII Midgar]], and even [[WesternAnimation/SpongeBobSquarePants Bikini Bottom]].[[note]]The first two probably happened because Creator/SquareEnix is the publisher of the game, and Square Enix isn't shy about doing cross-game promotions (see FFBE above).[[/note]] Oh yeah, and ''TabletopGame/Warhammer40000'' is included in there too, and you even get to clean up [[Franchise/BackToTheFuture the DeLorean]] for good measure.
234* ''VideoGame/PuzzleAndDragons'' frequently has "collaboration" events featuring crossover characters, the full list of which can be found by following the link. In the case of ''Puzzle & Dragons: Franchise/SuperMarioBros Edition'', this became its own standalone game.
235* If you thought Katy Perry being in a ''Final Fantasy'' game was weird enough, then have we got a story for you: the mobile game ''VideoGame/RagnarokOrigin'' once had an event centered around Music/{{Psy}}. Yes, the K-pop star responsible for "Gangnam Style."
236* ''VideoGame/RockBand'' has always had a wide scope in what kind of music it considers eligible for its track-list, and that becomes very clear with the inclusion of ''Music/SpongeBobSquarePants'' tracks for the show's MilestoneCelebration.
237** An episode of ''WesternAnimation/SouthPark'' had a brief gag where Cartman sang "Poker Face" by Music/LadyGaga on ''Rock Band''. Thing is, ''Rock Band'' didn't have "Poker Face" on their track-list at the time, so the devs added that song in response through DownloadableContent... both the original version ''and Cartman's version''.
238* ''[[VideoGame/SegaSuperstars Sonic & Sega All-Stars Racing]]'' and its sequel went bonkers with their non-Sega characters, each of them being unrelated to Sega as much as they are unrelated with the other guests. There's the platform-exclusive characters, [[VideoGame/BanjoKazooie Banjo & Kazooie]] (Xbox 360), MediaNotes/{{Mii}}s (Nintendo), and Pyro, Heavy, and Spy from ''VideoGame/TeamFortress2'' (PC), but it gets weirder from there. WesternAnimation/WreckItRalph is also a racer, and this was way before [[WesternAnimation/RalphBreaksTheInternet his sequel]] where he met Sonic. Then there's also LetsPlay/{{Yogscast}}, a group of content creators that primarily cover ''Minecraft'', and the weirdest of them all, Danica Patrick is there to cross-promote NASCAR and the game.
239* ''Franchise/SonicTheHedgehog'':
240** ''VideoGame/SonicDash'' had special events featuring characters from ''VideoGame/AngryBirdsEpic'' and ''Franchise/HelloKitty''. In the case of ''Angry Birds'', it went both ways and ''Epic'' had its own ''Sonic Dash'' event. ''Sonic Dash'' also received a crossover with the ''VideoGame/PacMan'' franchise, which oddly enough features the final official appearance of Ms. Pac-Man, due to the [[ExiledFromContinuity legal limbo]] that character is in.
241** Sonic also crossed over with the ''VideoGame/YoshisIsland'' and ''Franchise/TheLegendOfZelda'' franchises in ''VideoGame/SonicLostWorld'', including meeting the Link from ''VideoGame/TheLegendOfZeldaSkywardSword'' in the latter, though the weirdness is tempered a bit due to all three franchises having been in the ''VideoGame/SuperSmashBros'' series prior.
242* ''VideoGame/SoulSeries'':
243** Each version of ''Soulcalibur II'' features a unique GuestFighter. The Xbox port featured ComicBook/{{Spawn}}, who was a bit of an odd duck compared to the other two guests, the [=GameCube=] port's [[Franchise/TheLegendOfZelda Link]] and the [=PlayStation=] 2 version's [[Franchise/{{Tekken}} Heihachi Mishima]].
244** ''Soulcalibur IV'' went a step further and included guests from ''Franchise/StarWars''. To be fair, ''Star Wars'' is set "[[ALongTimeAgoInAGalaxyFarFarAway a long time ago in a galaxy far, far away]]", but having Mitsurugi cross blades with Darth Vader didn't make the inclusion feel any less [[FishOutOfTemporalWater bizarre]].
245* ''VideoGame/StreetFighterXMegaMan'' probably counts: It's a ''Franchise/MegaMan'' game, where instead of Robot Masters, Mega Man fights the World Warriors from ''Franchise/StreetFighter''.
246* ''Franchise/SuperMarioBros'' has had several strange crossovers, including:
247** A Mario ''VideoGame/DanceDanceRevolution'' game, called ''[[VideoGame/DanceDanceRevolutionMarioMix Mario Mix]]''.
248** Crossing ''Mario'' and ''Franchise/SonicTheHedgehog'' isn't too weird, as they're longtime rivals in similar genres. Crossing them both in the UsefulNotes/OlympicGames, however, [[VideoGame/MarioAndSonicAtTheOlympicGames is]].
249** Similarly, Mario has crossed over with ''VideoGame/DragonQuest'' characters... in ''VideoGame/FortuneStreet'', an investment board game.
250*** Other ''Fortune Street'' titles have had ''Dragon Quest'' and ''VideoGame/FinalFantasy'' together, which like ''Mario and Sonic at the Olympic Games'' wouldn't be too weird if not for the game genre of the crossover itself.
251** ''VideoGame/MarioPlusRabbidsKingdomBattle'', as the name implies, revolves around a portal opening up over the Mushroom Kingdom and unleashing [[VideoGame/RavingRabbids the Rabbids]] upon [[Franchise/SuperMarioBros Mario's]] world. Thus, Mario, Luigi, Peach, and Yoshi team up with four good Rabbids dressed like them to rid the kingdom of the Rabbids' usual brand of chaos before it screws it up beyond compare.
252** There's also Franchise/HelloKitty and WesternAnimation/ShaunTheSheep appearing in ''VideoGame/SuperMarioMaker''.
253** ''VideoGame/MarioKart8'' had several Mercedes-Benz cars designed after real-life ones, available in a DownloadableContent pack.
254* ''VideoGame/SuperSmashBros'':
255** ''Smash Bros.'' brings together many of Nintendo's franchises and a number of other gaming greats, which range from cartoony all-ages series (''Franchise/SuperMarioBros'', ''Franchise/{{Kirby}}'', ''Franchise/{{Pokemon}}'') to serious, more realistic fare (''Franchise/TheLegendOfZelda'', ''Franchise/{{Metroid}}'', ''Franchise/FireEmblem''). On the extreme ends, ''VideoGame/MetalGear'' and ''Franchise/{{Persona}}'' deal with adult issues and have tons of social commentary and ''VideoGame/{{Bayonetta}}'' is sexed up to the point that some consider it a parody, while ''VideoGame/AnimalCrossing'' is a conflict-free FunnyAnimal life sim and ''VideoGame/WiiFit'' is a ''fitness program''.
256** The trailers have been known to highlight the dissonance on occasion. The ''VideoGame/SuperSmashBrosUltimate'' reveals for both [[Franchise/{{Metroid}} Ridley]] and [[VideoGame/FinalFantasyVII Sephiroth]] showed them seeming to graphically slaughter Mario, while [[Franchise/{{Tekken}} Kazuya]]'s involved him disposing of the bodies of other fighters (though Sephiroth's was explicitly a BaitAndSwitch and Mario was not actually harmed).
257** A good example of how diverse the series is comes from the Hero from ''VideoGame/DragonQuest'' and VideoGame/BanjoKazooie, both revealed at E3 2019 for ''Ultimate''. ''Dragon Quest'' is a JRPG series which is relatively obscure series in the West, but over in Japan it's a cultural phenomenon comparable to the likes of other video game juggernauts like ''Franchise/{{Halo}}'' and ''Super Mario Bros.'' Meanwhile, ''Banjo-Kazooie'' is a platformer game developed by Creator/{{Rare}}, a Western developer now owned by Microsoft, is fondly remembered by many people who grew up with a Platform/Nintendo64, and the eponymous characters have been highly requested for ''Super Smash Bros.'' as fighters since [[VideoGame/SuperSmashBros64 the first]] ''Smash'' game came out back in '''1999'''. Many took note of contrast between the two after they had been revealed.
258* Speaking of ''Franchise/{{Tekken}}'', the series is no stranger to weird crossovers itself. ''VideoGame/Tekken7'', for example, includes within its roster of fighters [[Characters/TheWalkingDead2010NeganSmith Negan Smith]] from ''Franchise/TheWalkingDeadTelevisionUniverse'' and Noctis from ''VideoGame/FinalFantasyXV'', along with ''Franchise/StreetFighter''[='=]s Akuma playing a big role in the game's story.
259* ''VideoGame/TokyoMirageSessionsFE'' is an interesting example. A crossover between ''Franchise/FireEmblem'' and ''Franchise/ShinMegamiTensei'' already seemed pretty out-there, but the final game ended up being weird by virtue of not being very much like ''either'' series: instead being a LighterAndSofter, DenserAndWackier game about idol singers that just happened to have some ''SMT'' mechanics and ''Fire Emblem'' characters.
260* As of 2020, there are ''Toys/{{Tamagotchi}}'' virtual pet toys themed around ''Anime/NeonGenesisEvangelion''. The toys let you raise an Angel from the dramatic, serious, action-packed, and not-very-kid-friendly ''Evangelion'' anime, one of the last things one would expect the kid-friendly, cutesy, feminine, and not-very-action-packed ''Tamagotchi'' franchise to cross paths with.
261* The Japanese-only game ''Arthur to Astaroth no Nazomakaimura: Incredible Toons'', released for the Saturn and Playstation in 1996, is a direct port of the puzzle game ''VideoGame/SidAndAlsIncredibleToons'', except replacing the cartoon characters with the cast of ''VideoGame/GhostsNGoblins''.
262
263!!!Non-Commercial VideoGames / {{Fan Game}}s / {{Game Mod}}s
264* ''VideoGame/DeadIsland''
265** The game has the ''[[Manga/FistOfTheNorthStar Fist of the Dead Star]]'' mod, which alters the game's physics and unarmed combat mechanics, allowing the protagonists to hit very fast and very hard while running very fast and jumping very high, thus turning them into alternate versions of Kenshiro. Of course, someone made [[https://www.youtube.com/watch?v=hoLadZotBuE a montage of gameplay footage with music and sound effects from the anime adaptation]] (the music is the opening theme of the French version).
266** It becomes even funnier when you realize that unarmed combat specialist John Morgan, the new player character of ''VideoGame/DeadIslandRiptide'', has actually been created as a reference to this mod.
267* The ''VideoGame/TheElderScrollsVSkyrim'' modding community includes several ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' mods, as well as ''ComicBook/SpiderMan'' and even ''WesternAnimation/ThomasAndFriends'' ones.
268* ''VideoGame/EquestriaAtWar'' is a GameMod combining the detailed [=WW2=] political and military simulation of ''VideoGame/HeartsOfIron'' with the colourful world of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', where the show's characters are thrust into conflicts that must be solved like a true wars rather than with the magic of friendship. Like a true crossover, our world's politicians and generals that would appear in ''VideoGame/HeartsOfIron'' and its mods are present as well, albeit with modified names and the bodies of fantasy creatures, but they otherwise interact with the world and MLP's characters with their real-life personalities and ideals.
269* ''VideoGame/{{Fallout 3}}'' and ''VideoGame/FalloutNewVegas'' have ''Franchise/StarWars'' and ''ComicBook/{{Batman}}'' themed-mods. You can also [[http://www.nexusmods.com/newvegas/mods/36205/ replace Mr. House with Dr. House.]]
270* Part of the fun of ''VideoGame/{{MUGEN}}'' is mashing characters and stages together to make your ''own'' Weird Crossover. [[Franchise/MortalKombat Scorpion]] and Manga/{{Doraemon}} fighting on [[Manga/DragonBall Namek]]? Sure, why not!
271* ''VideoGame/PulpAdventures'' averts this in its main campaign. The mod's description mentions Franchise/ConanTheBarbarian, Franchise/{{Zorro}}, and [[Radio/TheLoneRanger the Lone Ranger and Tonto]] as playable characters alongside a long list of fictional characters from the Thirties (Franchise/IndianaJones, Literature/DocSavage, ComicBook/TheRocketeer, Radio/TheShadow, ComicStrip/JungleJim, ComicStrip/DickTracy, etc.), but it turns that Conan, Zorro, and the Lone Ranger are only playable in special missions representing the protagonists of the main storyline reading books. On the other hand, the Rumble Room mode (custom game) allows any combination of characters in the player's party, and the crossover can be even weirder since all the characters from the unmodded game (basically an AffectionateParody of MediaNotes/TheSilverAgeOfComicBooks) are available too.
272* ''VideoGame/SuperSmashFlash'' is a ''VideoGame/SuperSmashBros'' FanGame infamous for including the likes of {{Original Character}}s and {{anime}} characters. The first game has a justification via SerendipityWritesThePlot; it started out as a ''Franchise/SonicTheHedgehog'' FanGame that got {{retool}}ed into a ''Smash Bros.'' fan-game, and had to use whatever sprites were available at the time for its roster. The SurprisinglyImprovedSequel ''Super Smash Flash 2'' was initially planned to go in largely the same direction, including more content and features from the official games while adding a handful of {{Original Character}}s and anime characters (specifically from ''Magazine/ShonenJump'' due the existence of ''VideoGame/JumpUltimateStars'' providing high-quality sprites to use), until the head of the project realized just what kind of potential the game was capable of midway through development, and {{retool}}ed it into a more high-standard game. That meant that all the {{Original Character}}s were scrapped from the game, and the ''Shonen Jump'' characters would've been as well if not a few of them ([[Manga/{{Bleach}} Ichigo]], Franchise/{{Naruto}}, and [[Franchise/DragonBall Son Goku]]) already being coded into earlier demos, and stayed in by GrandfatherClause. Eventually, [[Franchise/OnePiece Monkey D. Luffy]] was added to the roster due to popular request and to round out the selection of ''Shonen Jump'' fighters.
273* In ''VideoGame/WolfensteinVsStreetFighter'', B.J. Blazkowicz fights his way through ''VideoGame/StreetFighterII'' themed levels and shoots soldiers that are Ryu.
274* ''VideoGame/CuriousExpedition'' is a Roguelike where the player character is a HistoricalDomainCharacter competing against four others to be the most famous explorer, the four contenders being player characters randomly chosen at the start of the campaign. There's several mods adding new player characters, including fictional characters, some of them being from ''vastly'' different work (also clashing with the Vanilla characters, who are all 19th and 20th historical characters). Since the contenders are randomly chosen from both Vanilla and mod characters, depending on the mods installed you may have Literature/SherlockHolmes (and Watson), [[ComicBook/DisneyDucksComicUniverse Scrooge McDuck]] (with Huey, Dewey, and Louie), [[Franchise/{{Rambo}} John Rambo]], and [[Literature/{{Discworld}} Rincewind]].[[note]]All of them are actual character mods available on the Steam Workshop[[/note]] Or any combination between mod fictional characters and historical Vanilla ones, such as Film/MadMax, [[Franchise/TombRaider Lara Croft]], Charles Darwin, Marie Curie, and Sir Francis Burton[[note]]the three latter are Vanilla characters[[/note]]. The Vanilla characters are arguably [[AnachronismStew an historical equivalent of this]]: some of them weren't even alive at the same time (Charles Darwin / HP Lovecraft, for instance).
275* ''VideoGame/CMCPlus'' is a standalone GameMod for ''VideoGame/SuperSmashBrosCrusade'', a ''VideoGame/SuperSmashBros'' FanGame developed with open support for modding - while ''Crusade'' is designed from its inception to have a roster that could pass for an official ''Smash'' one with a few exceptions, ''CMC+'' embraces the unlimited potential imagination of character mods such that its developers' only criteria for roster inclusion is mod quality control. This lets the game go completely ''ballistic'' with its crossover weirdness, surpassing even that of the first ''Super Smash Flash'': Not only does it have more {{Original Character}}s and non-video game characters than the first ''Super Smash Flash'', it showcases the bizarre side of crossovers upfront with the addition of CrackFic fighters such as parodic interpretations of UsefulNotes/BarackObama, [[UsefulNotes/McDonalds Ronald McDonald]] and [[UsefulNotes/KentuckyFriedChicken Colonel Sanders]]. And even when putting the CrackFic characters aside, its roster runs the gamut from whimsical, family-friendly cartoony fare (''VideoGame/AHatInTime'' and ''ComicStrip/{{Garfield}}'' on top of the ''Smash'' Nintendo mainstays) to dark and depressing tales for adults (''VideoGame/NierAutomata'', ''Anime/PuellaMagiMadokaMagica''), and from pop culture juggernauts and social phenomena (''Franchise/{{Halo}}'', Creator/MarvelComics, ''VideoGame/AmongUs'') to forgotten obscurities and properties that have completely fallen by the wayside of relevance in TheNewTwenties (''VideoGame/MonsterTale'', ''VideoGame/BlueDragon'', ''Anime/MyHime'').
276* ''VideoGame/RakenzarnTales'' is a [[MassiveMultiplayerCrossover massive crossover]] fangame that any character from any series can join in. It's essentially ''Franchise/KingdomHearts'' meets ''VideoGame/SuperSmashBros'' meets ''VideoGame/SuperRobotWars''. Some choices are typical but some come off as a little funny. We have the obvious choices like ''WesternAnimation/LooneyTunes'', Creator/{{Disney}}, ''Franchise/SuperMarioBros'', ''Franchise/SonicTheHedgehog'', and ''VideoGame/FinalFantasy''. Then we have the strange choices like ''Anime/QueensBlade'' and ''VideoGame/DIDNapper'', just to name a few.

279[[folder:Web Animation]]
280* The fondly-remembered "Music/TheUltimateShowdownOfUltimateDestiny" includes the likes of Franchise/{{Godzilla}}, ComicBook/{{Batman}}, Shaquille O'Neal, Music/AaronCarter, UsefulNotes/AbrahamLincoln, [[Franchise/{{Transformers}} Optimus Prime]], Creator/JackieChan, Franchise/IndianaJones, a Franchise/{{Care Bear|s}}, and the MemeticBadass himself, Creator/ChuckNorris. That's not going into {{the cameo}}s appearing in the chorus lines, or TheCavalry needed to take down Chuck Norris. [[spoiler: Oh, and the winner was Series/{{Mister Rogers|Neighborhood}}.]]
281* ''Manga/JoJosBizarreAdventure'' and the Franchise/DisneyAnimatedCanon are on complete opposite extremes of tone and content in animation, so a fusion of the two? See ''WebAnimation/JoJosBizarreAdventureOneCartoonistsDream''. [[MemeticMutation The next thing you'll say is,]] "That's ridiculous!" And you would be [[NarmCharm wrong, but also right.]]
282* [[https://www.youtube.com/watch?v=KKKhmkPtUSk See also]] a UsefulNotes/MikuMikuDance video of the ''[=JoJo=]'s'' villains [[VillainsOutShopping performing]] [[VisualNovel/UtaNoPrinceSama "Maji Love 1000%"]].

286* Goldenmoustache ''[[http://www.goldenmoustache.com/le-groupe-facebook-secret-des-grands-mechants-92271/ Le groupe Facebook]] [[http://www.goldenmoustache.com/le-groupe-facebook-secret-des-grands-mechants-2-97047/ SECRET des]] [[http://www.goldenmoustache.com/le-groupe-facebook-secret-des-grands-mechants-3-103373/ Grands Méchants]]'' ("The Big Bads' Secret Facebook Group") is made of fake Facebook screenshots with comments of real-life dictators (UsefulNotes/AdolfHitler, UsefulNotes/JosefStalin, UsefulNotes/MaoZedong, [[UsefulNotes/TheRulersOfNorthKorea Kim Jong-Un]], UsefulNotes/SaddamHussein, etc.), current controversial personalities ([[https://en.wikipedia.org/wiki/Marine_Le_Pen Marine Le Pen]], [[https://en.wikipedia.org/wiki/J%C3%A9r%C3%B4me_Kerviel Jérôme Kerviel]], etc), and fictional villains ([[Franchise/StarWars Darth Vader]], [[Literature/TheLordOfTheRings Sauron]], the T-Rex from ''Franchise/JurassicPark'', [[WesternAnimation/{{Aladdin}} Jafar]], [[Franchise/TeenageMutantNinjaTurtles Shredder]], [[Literature/TheSilenceOfTheLambs Hannibal Lecter]], etc).
287* On the French Internet, the announcement of Creator/OmarSy having a supporting role in ''Film/XMenDaysOfFuturePast'' led to a recurrent joke about Omar Sy playing the same character as in ''Film/{{Intouchables}}'', now hired by Professor Xavier as his care-giver.
288* The WildMassGuessing pages on this very wiki are occasionally guilty of this when imagining connections between totally unrelated works and universe (''especially'' when trying to create connections with ''Series/DoctorWho'').
289* [[https://knowyourmeme.com/memes/i-think-were-gonna-have-to-kill-this-guy-steven "I Think We're Gonna Have To Kill This Guy, Steven"]] [[MemeticMutation memes]], which are fan edits of Haus of Decline's ''WesternAnimation/StevenUniverse'' [[https://twitter.com/hausofdecline/status/1647604800329072642 parody comic]] about Steven trying to negotiate UsefulNotes/AdolfHitler and Garnet suggesting Steven to kill him. People pair two characters from incompatible medias with one of them saying "I think we're gonna have to kill this guy, X" behind. The SurrealHumor along with NothingIsFunnier aspect makes this meme spread like wildfire.
290[[/folder]]
291
292[[folder:Web Videos]]
293* ''WebVideo/DerDisneygang'' is a crossover between the characters from the ''WebVideo/HitlerRants'' meme and the Disney Universe. In this crossover, Hitler legally buys the Disney brand, allowing him to rule over Disney with an iron fist. His arch nemesis Hermann Fegelein does not like this and starts a revolution against the Nazis.
294* The parodic French webseries ''Series/FlandersCompany'' is set in an universe in which appear very thinly veiled {{Lawyer Friendly Cameo}}s of various Creator/MarvelComics and Creator/DCComics characters, [[Franchise/StarWars Darth Vader]], [[Franchise/SuperMarioBros Mario and Luigi]], Franchise/HarryPotter, Franchise/{{Naruto}}, etc. The supervillains' highest authority seems to be a council featuring ComicBook/LexLuthor, ComicBook/{{Magneto}}, ComicBook/DoctorDoom, and Darth Vader.
295* ''[[http://www.dailymotion.com/video/xntgco_intouchables-feat-drive_shortfilms Intouchables (Feat Drive)]]'' is ''Film/{{Intouchables}}'' opening's scene, with the soundtrack replaced by the ''Film/Drive2011'' opening theme.
296* ''[[https://www.youtube.com/watch?v=Nsi06PG7w_0 Wes Anderson's The Shining]]'' (AKA ''The Grand Overlook Hotel''), is, you guessed, a fake trailer mixing ''Film/TheShining'' and ''Film/TheGrandBudapestHotel''.
297* ''[[https://www.youtube.com/watch?v=Xd1LstoEm8U Trololol S.T.A.L.K.E.R.]]'' is gameplay footage of ''VideoGame/{{STALKER}}: Shadow of Chernobyl'' (the Agroprom area) edited to sound like the famous [[https://www.youtube.com/watch?v=n2bKLqUKb9w Trololol Song]] was among the Zone's anomalies.
298* ''WebVideo/PoohsAdventures'': The series has many characters from completely different genres.
299* ''WebVideo/TheLifeAndTimesOfBullyDemise'' starts as a playthrough of various [=MDickie=] games, but culminates in a a crossover between games like ''VisualNovel/VirtuesLastReward'', ''VideoGame/{{Mode}}'', ''VideoGame/SpyFiction2003'', and more, all under the banner of professional wrestling.

301
302[[folder:Western Animation]]
303* ''WesternAnimation/BambiMeetsGodzilla''. ExactlyWhatItSaysOnTheTin.
304* Each episode of ''WesternAnimation/TheNewScoobyDooMovies'' has the Mystery Machine gang meet up with one or more people from out-of-universe, potentially from anywhere. Though most are simply celebrity guest stars, other franchises that have crossed over with this series include ''ComicBook/{{Batman}}'', ''Series/TheAddamsFamily'', ''Film/TheThreeStooges'', ''WesternAnimation/JosieAndThePussycats'', and WesternAnimation/TheHarlemGlobetrotters. Each time, the villain comes from the guest star's universe or at least fits their theme. It's notable that encountering mystical characters like Jeannie or the Addams Family doesn't faze [[AgentScully Velma]] in the slightest. Scooby and his friends' tendency to meet up with characters from other random series gets [[ParodiedTrope parodied]] in ''WesternAnimation/JohnnyBravo'' when he runs into them and he proves to be much less useful than any of the previous crossover characters.
305** The SpiritualSuccessor ''WesternAnimation/ScoobyDooAndGuessWho'' has seen team ups with characters such as Urkel from ''Series/FamilyMatters''.
306* ''WesternAnimation/BatmanTheBraveAndTheBold'' usually teamed Batman up with other DC Comics characters, but sometimes it went a little further out; bringing in Franchise/SherlockHolmes and Dr. Watson, the cast of ''Franchise/ScoobyDoo'', Music/WeirdAlYankovic, WesternAnimation/SpaceGhost, and Jeff "The Roastmaster" Ross.
307* The Emmy Awards committee produced ''WesternAnimation/CartoonAllStarsToTheRescue'', and had it simulcast on all three networks on Saturday 21 April 1990. The well-intentioned but hopelessly hamfisted effort to discourage drug abuse roped in characters from Creator/{{Disney}}, Creator/WarnerBros, Creator/DiCEntertainment, Creator/JimHenson, Series/{{ALF}}, Franchise/{{Garfield}}... Few studios were spared, resulting in a WhatWereYouThinking hodgepodge production.
308* Another [[Franchise/TheDCU DC]]/WesternAnimation/LooneyTunes example: The ''WesternAnimation/DuckDodgers'' episode "[[Recap/DuckDodgersS1E9 The Green Loontern]] sees the titular character teaming up with the [[ComicBook/GreenLantern Green Lantern Corps]].
309* Surprisingly averted with ''WesternAnimation/FredAndBarneyMeetTheThing'', an hour long cartoon block in 1979. Creator/HannaBarbera's Fred Flintstone and Barney Rubble never meet Creator/MarvelComics' ComicBook/TheThing from ''ComicBook/FantasticFour''. The show paired a half hour of ''The New Fred And Barney Show'' with another half hour of Ben Grimm, who could use his "Thing Ring" to transform from normal human to living rock being and back, contradictory to Marvel canon. Obviously, the show's title is a complete misnomer.
310** The show was later renamed ''Fred and Barney Meet the [[ComicStrip/LilAbner Shmoo]]''. However, they didn't meet the Shmoo either, the little creature once again having its own separate segments. The trope was finally played straight in the later ''WesternAnimation/TheFlintstoneComedyShow'' series, where they ''did'' actually meet the Shmoo in the ''Bedrock Cops'' segment, which features the three as part-time cops.
311* ''WesternAnimation/LiloAndStitchTheSeries'' had crossovers with ''WesternAnimation/KimPossible'', ''WesternAnimation/AmericanDragonJakeLong'', ''WesternAnimation/{{Recess}}'', and ''WesternAnimation/TheProudFamily'', thus connecting them all into a SharedUniverse of a {{Fantasy|Kitchen Sink}} and SciFiKitchenSink. This is especially strange for the latter two shows which are pretty much SliceOfLife shows.
312** However, ''Recess'' did have [[spoiler: Santa Claus actually existing]] along with the movie showing off various high level sci-fi equipment including a ''tractor beam'' while ''WesternAnimation/TheProudFamily'' did have two episodes involving a DealWithTheDevil with a Faustinian cariacature of ''Al Roker'', the superpower granting Proud Scary Snacks in their Halloween special and their own film involving ''mutated peanut people.'' Suddenly, the crazier moments of MagicalRealism make a lot of sense.
313* ''WesternAnimation/OKKOLetsBeHeroes'':
314** "The Power Is Yours!" is a crossover with ''WesternAnimation/CaptainPlanetAndThePlaneteers'', an infamous EdutainmentShow from TheNineties.
315** "Monster Party" has the girls from ''WesternAnimation/ScoobyDooAndTheGhoulSchool'' as childhood friends of Enid.
316** [[Franchise/SonicTheHedgehog Sonic & Tails]] even shows up in the show! Apparently, Sonic is a famous hero in this universe.
317* The ''WesternAnimation/SouthPark'' ''[[Recap/SouthParkImaginationland Imaginationland]]'' trilogy uses this as a part of its premise. Since the story is set in an alternate dimension created from the imagination of humanity, most of the supporting characters are already existing fictional characters. The rulers of Imaginationland are the Council of Nine, which members are [[Literature/TheChroniclesOfNarnia Aslan the Lion]], [[Literature/TheLordOfTheRings Gandalf the Grey]], [[Film/TheWizardOfOz Glinda the Good Witch]], UsefulNotes/{{Jesus}} (who is shown in Imaginationland despite existing in the ''South Park'' universe), [[Franchise/StarWars Luke Skywalker]], [[Franchise/TheMatrix Morpheus]], ComicStrip/{{Popeye}}, ComicBook/WonderWoman, and [[Myth/ClassicalMythology Zeus]]. The Evil side includes, among others, [[Franchise/FridayThe13th Jason Voorhees]], [[Franchise/TheLegendOfZelda Ganondorf]], the ghosts from ''VideoGame/{{PacMan}}'', ComicBook/{{Darkseid}}, etc. A more exhaustive list of ''Imaginationland'' characters can be found [[http://southpark.wikia.com/wiki/List_of_Characters_from_Imaginationland here]].
318* The ''WesternAnimation/StevenUniverse'' episode "Say Uncle" is a crossover with ''WesternAnimation/UncleGrandpa'', which is DenserAndWackier than ''Steven Universe''. The episode begins with a declaration that this is a FakeCrossover, and ends with Uncle Grandpa running down a checklist of other CN series he's visited -- and the ''WesternAnimation/SwatKats'' [[UnexpectedCharacter are on the list, too]].
319* AgentScully and AgentMulder of ''Series/TheXFiles'' appear on ''WesternAnimation/TheSimpsons'' when Homer reports seeing an alien.

323* Creator/LesInconnus use this trope at a point in the skit [[https://www.youtube.com/watch?v=tqdk0k_U8Zg "Les Escarres".]][[note]]literally "the bedsore", it's actually a pun about [[MediaNotes/AcademyAward the Oscars]] and their French equivalent the [[https://en.wikipedia.org/wiki/C%C3%A9sar_Award César Awards]][[/note]] One of the speeches given during the ceremony is spoken by a fake Japanese moviemaker, saying that his company has future movie projects with titles like ''Return of [[Literature/LesMiserables Jean Valjean]] and [[Series/ChoudenshiBioman Bioman]]'', and ''Theatre/CyranoDeBergerac Versus Franchise/TeenageMutantNinjaTurtles''.

325** [[http://www.cracked.com/article_18785_6-comic-book-crossovers-you-wont-believe-actually-happened.html 6 Comic Book Crossovers You Won't Believe Actually Happened]] is focused on official (i.e. non fan-made) crossovers whiche are: ComicBook/{{Batman}}[=/=]Franchise/SherlockHolmes, ComicBook/ThePunisher[=/=]Music/{{Eminem}}, UsefulNotes/{{Jesus}} [[CrossoverCosmology Versus]] [[Myth/ClassicalMythology Zeus]], ''ComicBook/XMen''[=/=]''Franchise/StarTrek'', ComicBook/SpiderMan and ComicBook/IronMan[=/=]''Series/GuidingLight'', and ComicBook/{{Superman}}[=/=]''Absolutely Anything'' (the article refers to crossovers with ''Franchise/MastersOfTheUniverse'' or ''the Quik Mascot'', of all things).
326** [[http://www.cracked.com/article_20113_5-insane-pop-culture-crossovers-that-almost-happened.html 5 Insane Pop Culture Crossovers That Almost Happened]] is a WhatCouldHaveBeen variant of the previous one, since it focused on official crossover projects which eventually didn't happen: ComicBook/GhostRider[=/=]WesternAnimation/CasperTheFriendlyGhost, Franchise/{{Rocky}} Balboa[=/=]''Franchise/GIJoe'', ''Series/QuantumLeap''[=/=]''Series/MagnumPI'', and ''[[Film/JayAndSilentBobStrikeBack Jay and Silent Bob]]''[=/=]''Franchise/{{Hellraiser}}''.[[note]]The fifth one isn't an actual crossover but the aborted concept of the third ''Film/{{Jaws|3D}}'' movie initially supposed to be a ''Film/NationalLampoon'' film[[/note]]
327** And then, there are several articles [[http://www.cracked.com/article_19992_5-fan-fiction-sex-scenes-you-wont-believe-exist.html about surreal]] [[http://www.cracked.com/article_20471_the-5-most-horrific-sex-scenes-in-fan-fiction-history.html sex scenes]] [[http://www.cracked.com/article_16554_the-5-most-baffling-sex-scenes-in-history-fanfiction.html taken from]] [[http://www.cracked.com/article_21189_the-6-most-horrifying-sex-scenes-in-fan-fiction-pt.-4.html fanfics]] (not necessarily all involving crossovers, though they often do).

328* In the ''WesternAnimation/{{Futurama}}'' episode "The Impossible Stream", one of the shows seen while Bender is flipping through the channels is ''Franchise/AlienVsPredator vs. WesternAnimation/{{Bluey}}''. The former two being horror films and the latter being a preschool show.
