History Main / WeirdCrossover

* Another [[Franchise/TheDCU DC]]/WesternAnimation/LooneyTunes example: The ''WesternAnimation/DuckDogers'' episode "[[Recap/DuckDodgersS1E9 The Green Loontern]] sees the titular character teaming up with the [[ComicBook/GreenLantern Green Lantern Corps]].

* During 2013, 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}}''!

** 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'' and ''VideoGame/TheLastOfUs'', starring the HBO series' Creator/PedroPascal himself.

For [[UsefulNotes/{{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.

** 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 UsefulNotes/SuperNintendoEntertainmentSystem game, something Nintendo wouldn't allow at least until late 90s, unless if it's a bootleg.[[/note]].

* ''[[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), UsefulNotes/{{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.

* ''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 UsefulNotes/TheSilverAgeOfComicBooks) are available too.

* 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 [[UsefulNotes/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''.

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

A 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 he[=/=]she is 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.

* The farmland 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?".

** And there was also the time when ''VideoGame/MarioKart8'' had an actual real life Mercedes-Benz car. Like, one you can actually buy and drive yourself. I'm sorry, but who asked for this?

** Finally, ''Fanfic/InfinityTrainVoyageOfWisteria'' has a storyline where the Apex kids have to be dragged into the [[WebAnimation/HazbinHotel The Hazbin Car.]]
