History Main / CommonCrossover

** The Veil of Death from the Department of Mysteries is sometimes also used as a link to the GateOfTruth, and as well-written stories such as ''[[http://www.fanfiction.net/s/6436196/1/Penance Penance]]'' can attest, it can work to a strong degree.

** As for Specific Fandoms, crossovers with ''Franchise/{{Resident Evil}}'' can occasionally happen, with both series being famous for their impact on the SurvivalHorror genre, being competitors at the start, and having similarities to each other. It also helps that the Resident Evil characters in particular, can barely catch a break in terms of trauma from the events of the series making them easy candidates to get stuck in Silent Hill, or even helping the other characters out in Silent Hill.

** To put things in perspective: Website/ArchiveOfOurOwn lists the top 10 most popular characters in every fandom, and [=OTGW=]'s list includes Dipper, Mabel and Bill Cipher.

* ''VideoGame/TalesOfVesperia'' and ''Blazblue''. At least according to the author of the fanfic. Though it's in the Tales of section rather than the Crossover section.

* ''Series/{{Castle|2009}}'' and ''Series/{{Bones}}'' seem to be crossed over a fair bit. There's also more than a few crossovers with ''Series/{{Firefly}}'' that tend to suggest some kind of connection between Richard Castle and Malcolm Reynolds (although the sheer amount of {{Actor Allusion}}s ''Series/{{Castle}}'' makes to ''Series/{{Firefly}}'' help this along).

* ''WesternAnimation/{{Amphibia}}'' and ''WesternAnimation/TheOwlHouse'' are extremely common to make crossovers between. The reason is simple: They are very similar shows, that released within a year of each other, and most fans of one show are also fans of the other. It's to the point that it's almost {{Fanon}} that they are set in the same multiverse. Supporting this, a scene in ''Owl House'' briefly shows Anne, the protagonist of the former show, in a news page as a missing girl, indicating the two may be actually taking place in a shared universe.

* ''WesternAnimaton/HazbinHotel'': Pick a character whose primary trait is killing Demons or otherwise going to Hell. Somehow, all roads for them will lead to the titular Hotel. Prominent examples include [[VideoGame/{{Doom}} Doomguy]], [[VideoGame/DevilMayCry Dante]]. [[VideoGame/{{Ultrakill}} V1]], [[VideoGame/{{Helltaker}} the Helltaker]], and even freakin' ''[[Fanfic/APeacefulAfterlife Yoshikage Kira]]''.

** With ''WesternAnimation/TeenTitans'', mostly because of Raven/Naruto, two people with pasts involving demons. It helps that ''Teen Titans'' ends with Raven unattached.

* ''WesternAnimation/DannyPhantom'' / ''WesternAnimation/TeenTitans'' crossovers are common amongst the fandom.

[[/folder]]

* The Franchise/CthulhuMythos fits well with anything vaguely fantasy, horror, sci-fi, or mystery, from ''Literature/SherlockHolmes'' to ''TabletopGame/DungeonsAndDragons'' to the MarvelUniverse. Hence ''TabletopGame/CthulhuTech''. There was even a ''Franchise/{{Batman}}'' Elseworld that revolved around Arkham Asylum crossed over with the Cthulhu Mythos, making it a professional version of this trope.

** Third Edition campaign ''Red Hand of Doom'' and Fifth Edition ''TabletopGame/TyrannyOfDragons'' are often placed in the ''TabletopGame/{{Dragonlance}}'' universe, due to the fact that the BigBad of that setting, dragon queen Takhisis, is a blatant {{Expy}} of the main villain of the two modules, dragon godess Tiamat.

** This reaches the logical conclusion with the ''Amalgam'Verse'', as shown in the fanfics ''Fanfic/TheBridge'' and ''Fanfic/GodzillaNewEra''- nearly every kaiju story ''ever'', from the aforementioned Godzilla, Gamera, Ultra Series, and Pacific Rim, straight through to Film/Cloverfield, Film/Gorgo, and even numerous American 50s giant monster movies, have been fused into a single world, using the Heisei Godzilla series as the base and building from there. Though at first it existed only to provide background for ''The Bridge'', [[WeirdCrossover a crossover with My Little Pony]], it has since been expanded on via ''New Era'' and the series of short stories called ''Tales of the Amalgam'Verse''.
