* ''TabletopGame/TheWorldOfDarkness'' is a MorePopularSpinoff of ''TabletopGame/ArsMagica'', though the two gamelines are now thoroughly divorced from one another (and suggesting a crossover of the two is [[DorkAge not a good idea]]). Nonetheless, a large percentage of current Ars Magica fans discovered the game after coming from the World of Darkness and following the trail of the [[TabletopGame/MageTheAscension Order of Hermes]] and the [[TabletopGame/VampireTheMasquerade Tremere]].

* ''Webcomic/IWantToBeACuteAnimeGirl'' and ''Webcomic/Rain2010''. due to both comics being centered around a trans girl and her supportive friends.

* On Twitter fans of Franchise/{{Batman}} on and off antagonist/love interest Talia Al'Ghul, ComicBook/GreenArrow villain Shado, ComicBook/TeenTitans villain Cheshire and ComicBook/LadyShiva has come together as a "Murdermoms" fandom, bonding over the fact all four characters are extremely deadly assassins, have complicated relationships with their good-aligned children (Damian Wayne, Emiko Queen, Lian Harper and Cassandra Cain, respectively) and suffer from numerous writers trying to make them more villainous than their fans actually like them to be.

* Among ''Naruto'' fanfictions, ''Fanfic/TruePotential'' and ''Fanfic/SonOfTheSannin'' share many of the same readers, as both fanfics feature Naruto in a different team with Hinata under a female sensei that doesn't get much spotlight in the manga, heavy focus on the jinchuriki as characters as opposed to mere {{MacGuffin}}s, and arcs covering similar topics (such as the Kirigakure Civil War, or Hidan and Kakuzu invading Takigakure to capture Fu). The fact that the authors are friends and enjoy and reference each other's fanfic helps as well.
* Among ''My Hero Academia'' fics, ''Fanfic/AmazingFantasy'', ''Fanfic/NeitherABirdNorAPlaneItsDeku'' and ''Fanfic/ThievesCanBeHeroes''. The authors have professed to be fans of each others' work and the three of them went so far as to reference each other as being part of the same multiverse. It's perhaps best shown by [[https://images-wixmp-ed30a86b8c4ca887773594c2.wixmp.com/f/fb799238-e124-4857-a88e-7f95bc55eec0/ddjokyk-667787e3-0519-4a12-8408-49b394314fbe.jpg?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ1cm46YXBwOjdlMGQxODg5ODIyNjQzNzNhNWYwZDQxNWVhMGQyNmUwIiwiaXNzIjoidXJuOmFwcDo3ZTBkMTg4OTgyMjY0MzczYTVmMGQ0MTVlYTBkMjZlMCIsIm9iaiI6W1t7InBhdGgiOiJcL2ZcL2ZiNzk5MjM4LWUxMjQtNDg1Ny1hODhlLTdmOTViYzU1ZWVjMFwvZGRqb2t5ay02Njc3ODdlMy0wNTE5LTRhMTItODQwOC00OWIzOTQzMTRmYmUuanBnIn1dXSwiYXVkIjpbInVybjpzZXJ2aWNlOmZpbGUuZG93bmxvYWQiXX0.CmwvhoTbOtB-kMKCpnl8PM50rzwFbqT-o54nruZEBaI this fanart]] of the stories' respective Izukus together.

* Among ''Naruto'' fanfiction, ''Fanfic/TruePotential'' and ''Fanfic/SonOfTheSannin'' share many the same readers, as both fanfics feature Naruto in a different team with Hinata under a female sensei that doesn't get much spotlight in the manga, heavy focus on the jinchuriki as characters as opposed to mere {{MacGuffin}}s, and arcs covering similar topics (such as the Kirigakure Civil War, or Hidan and Kakuzu invading Takigakure to capture Fu). The fact that the authors are friends and enjoy and reference each other's fanfic helps as well.

* Fanfic/AManOfIron fans and [[Fanfic/TheInfiniteLoops The Jurassic Loops]]. Mr. Chaos and GarnettFox are friends and many fans of each story have crossed over to try out the other. Tends to be the case when it comes to many of Mr. Chaos' stories, as he is a massive supporter of Fanfiction and will regularly direct people to try out new stories. He also has happily encouraged people to borrow ideas he originally came up with to help start their own stories, resulting in shared fandoms.

** ''VideoGame/{{Helltaker}}'' creator Vanripper often cites Monster Prom as his inspiration to create his game and some of his fanart of it even made it to the in-game Monster Prom gallery. But their respective fandoms truly bonded when [[HornyDevil Modeus]] was announced as a playable character in Monster Prom's sequel, ''Monster Camp''.

* ''WesternAnimation/RiseOfTheGuardians'', ''WesternAnimation/HowToTrainYourDragon'', and ''WesternAnimation/TheCroods'' fans tend to get along well primarily because said fans have a parituclarly strong liking to the central teenage, male character of each film ([[AnIcePerson Jack Frost]], [[DragonRider Hiccup Haddock]], and [[TheSmartGuy Guy Crood]]), respectively.

* Creator/RoosterTeeth fans have a significant degree of overlap with fans of Freddie Wong (due to the two being good friends), LetsPlay/SeaNanners (since Adam started as a Rooster Teeth fan before breaking out on his own), ''Machinima/ArbyNTheChief'' (since creator Jon Graham and Rooster Teeth get on extremely well and have collaborated many times) and ''Franchise/{{Halo}}'' (owing to their flagship series ''Machinima/RedVsBlue'').

* While there are many Minecraft roleplay series on the internet, there are four that ''really'' took off in the early 2020s; ''LetsPlay/DreamSMP'', ''LetsPlay/EmpiresSMP'', ''LetsPlay/LastLifeSMP'' and the ''LetsPlay/HermitcraftServer'' (though Hermitcraft was already popular beforehand). Naturally, there's quite a bit of overlap between fandoms, especially with the latter three. Fans often reassure one another when a particularly painful piece of lore drops (for example, Dream SMP fans trying to comfort Last Life fans when Last Life's Season 2 finale dropped on November 16th, a very significant date for Dream SMP fans), and the different roleplay styles of each server are often compared and contrasted for comedic purposes.[[note]]Hermitcraft puts the roleplay second to actual gameplay and generally keeps things very light, Last Life is very roleplay-focused but doesn't take itself too seriously, Empires takes its roleplay very seriously but sticks to a high-fantasy aesthetic and keeps the tone fairly light, and DSMP also takes its roleplay very seriously, but does not shy away from exploring extremely dark themes like war, trauma, mental illness and abuse.[[/note]]

* The fandoms for Creator/{{Sprout}} and Creator/NickJr are very good friends, even to this day.

[[/folder]]

* ''Literature/HarryPotter'' and ''Literature/TheHungerGames'' fans are best buddies. They've oftentimes joined together [[FandomRivalry against]] ''Literature/{{Twilight}}''. In any case, there are loads of "The Potter Games" and "District 9¾" pages with an emblem of an owl carrying a broom inside the Mockingjay pin.

* Among ''Naruto'' fanfiction, ''Fanfic/TruePotential'' and ''Fanfic/SonoftheSannin'' share many the same readers, as both fanfics feature Naruto in a different team with Hinata under a female sensei that doesn't get much spotlight in the manga, heavy focus on the jinchuriki as characters as opposed to mere {{MacGuffin}}s, and arcs covering similar topics (such as the Kirigakure Civil War, or Hidan and Kakuzu invading Takigakure to capture Fu). The fact that the authors are friends and enjoy and reference each other's fanfic helps as well.

* In the same way as AEW and NXT, current top joshi promotions ''Wrestling/{{TJPW}}'' and ''[[Wrestling/WorldWonderRingStardom STARDOM]]'' are practically friendly rivals at the most, which if you look at it both promotions kinda complement each other (i.e. one promotion covering the other's weaknesses).

* Fans of various Creator/MarvelComics books about teenage superheroes -- ''ComicBook/{{Runaways}}'', ''ComicBook/AvengersAcademy'', ''ComicBook/YoungAvengers'', ''ComicBook/NewMutants'', ''[[ComicBook/NewXMenAcademyX New X-Men]]'', ''Sentinel'', ''Gravity'', ''ComicBook/AvengersTheInitiative'', Sam Alexander ComicBook/{{Nova}}, ''ComicBook/NewWarriors'', ''ComicBook/JourneyIntoMysteryGillen'', ''ComicBook/LokiAgentOfAsgard'', ''ComicBook/MsMarvel2014'', ''ComicBook/AllNewGhostRider'', ''ComicBook/TotallyAwesomeHulk'', ''ComicBook/{{Ironheart}}'', ''ComicBook/TheUnbelievableGwenpool'', ''ComicBook/TheUnbeatableSquirrelGirl'', ''ComicBook/UnstoppableWasp'', ''ComicBook/MoonGirlAndDevilDinosaur'' and so on -- tend to stick together. This also extends to various Spider-themed teens from alternate universes, like ''ComicBook/SpiderGirl'', ''ComicBook/UltimateSpiderMan'' or ''ComicBook/SpiderGwen''. And while not all of them like the main Franchise/SpiderMan, he is getting a lot of respect for how influential his original stories were to the genre. Titles like ''ComicBook/AllNewAllDifferentAvengers'' or ''ComicBook/{{Champions|2016}}'' tried to capitalize on it by bringing up several of these characters together and further strengthening the fandom bonds.

** ''Film/SpiderManNoWayHome'', due to its premise, managed to bring fans of the MCU Spider-Man, fans of the ''Film/SpiderManTrilogy'' and fans of ''Film/TheAmazingSpiderManSeries'' together in celebration. There had been ''much'' rivalry over who's the best actor between Creator/TobeyMaguire, Creator/AndrewGarfield and Creator/TomHolland, and this film's [[TheMultiverse Multiverse]] approach at least signifies that neither Maguire nor Garfield have been forgotten by Creator/SonyPictures and Creator/MarvelStudios and haven't been invalidated due to the {{Continuity Reboot}}s.

[[folder:Western Animation]]
* ''WesternAnimation/BobsBurgers'' with ''WesternAnimation/{{Archer}}'' due to Creator/HJonBenjamin starring as the titular characters in both series. The Season 4 premiere of the latter was a crossover episode where Archer has amnesia and thinks he's Bob Belcher. The season 4 finale guest starred Eugene Mirman and Creator/KristenSchaal as one-off characters, both using the same voices they use for Gene and Louise respectively.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Fans of ''WesternAnimation/EdEddNEddy'' moved on to this show, since both shows have a similar tone, the latter show has some of the same cast and crew as the former, and the target demographic of the former (kids) is now the PeripheryDemographic of the latter (college students).
** Many fans of ''WesternAnimation/ThePowerPuffGirls'' and ''WesternAnimation/FostersHomeForImaginaryFriends'' also got into ''Friendship Is Magic'' because of Creator/LaurenFaust's contributions to all three shows.
** ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fans are on very good grounds with ''WesternAnimation/GravityFalls'', ''WesternAnimation/AdventureTime'', ''WesternAnimation/RegularShow'', ''WesternAnimation/SpongeBobSquarePants'', ''WesternAnimation/InvaderZim'' and even modern ''WesternAnimation/SouthPark'' fans, mostly due to certain similarities between various characters and humor (with Zim having less similarities to [=SpongeBob=] as the others). ''WesternAnimation/TheMarvelousMisadventuresOfFlapjack'' as well, since some members of the crew went on to be involved in shows such as ''Gravity Falls'', ''Adventure Time'', and ''Regular Show''.
** Going back a little further, fans of ''WesternAnimation/{{Doug}}'' and ''WesternAnimation/HeyArnold'' are very friendly with fans of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', due to the similar SliceOfLife nature between the shows. This also makes sense, considering those who [[TheNineties grew up watching the two Nickelodeon shows]] (with a ChannelHop for the former) are in the PeripheryDemographic for ''[=FiM=]''.
** Fans of ''WesternAnimation/AvatarTheLastAirbender'' and its sequel, ''WesternAnimation/TheLegendOfKorra'', have a friendly rivalry with fans of ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Things can get pretty heated over [[FandomRivalry which of the two is better]], but there's a lot of crossover between the two fandoms, and most of those who aren't fans of both are still pretty cool with the other show.
** ''WesternAnimation/DanVs'' fans and bronies tend to get along quite well, with fans from both sides often citing that the shows are the absolute [[OppositesAttract polar opposites]] of each other.
** Bronies and fans of ''WesternAnimation/StevenUniverse'' get along quite well due to the similar nature of the shows and both fanbases sharing a lot of members. This is in spite of a [[VocalMinority small but loud]] portion of the latter's fans that tried to stir up trouble over a certain event and trigger a FandomRivalry, and a handful of bronies even claim [[NiceJobFixingItVillain is how they came to learn of Steven Universe to begin with]].
** The fandoms of both this show and ''WesternAnimation/SofiaTheFirst'' generally get along well due to how they're both TV-Y rated shows that reinvigorated interest for shows in their respective networks, on top of similarly catchy music, and themes on love, family, and friendship.
* ''WesternAnimation/{{Beetlejuice}}'' and ''WesternAnimation/TheRealGhostbusters'', for several reasons. They’re both well-received {{Animated Adaptation}}s of live action movies from the 80s, their premises both feature characters dealing with ghosts like it’s no big deal, and they were both early attempts to break out of the AnimationAgeGhetto via solid writing
* Fans of ''WesternAnimation/TheAmazingWorldOfGumball'' are open to anything. This is both ironic and fitting, given the show’s context. The only thing the fans (and even the show itself) legitimately dislike is the Chinese knockoff, ''Animation/MiracleStar''.
* A rather odd example: the fandoms of ''WesternAnimation/HeyArnold'' would often get along with fans of ''WesternAnimation/{{Recess}}'' and have grown to have mutual respect for each other, probably due to the similarities between the two shows. This used to be the reason they originally [[FandomRivalry hated each other]], but now that there is no threat of competition, fans of either are now often fans of both. [[note]]However, see WesternAnimation/{{dueling shows}}, as ''Recess'' is the winner against ''Hey Arnold'', even though the latter came out first.[[/note]]
* Many of the prominent {{Fanfic}} writers for ''WesternAnimation/AdventuresOfTheGalaxyRangers'' also wrote fanfic for ''WesternAnimation/JonnyQuestTheRealAdventures'' back in the 1990s. These days, newcomers to the fandom tend to be fans of ''WesternAnimation/XMenEvolution'' who discovered it via Red Witch and other fanfic writers. Later on, the ''Galaxy Rangers'' fan writers ended up writing ''Series/{{Leverage}}'' fanfic, partly because of the similarities in the character types (Doc and Hardison, Nathan and Zach, Shane and Spencer).
* There's a lot of overlap between fans of ''WesternAnimation/TheLegendOfKorra'' and ''WesternAnimation/YoungJustice''--both are slightly dark series written with a preteen/teenage crowd in mind, and ''Young Justice'' aired on Cartoon Network in the time slot right before ''The Legend of Korra'' on Nickelodeon.
* In the same block as ''WesternAnimation/YoungJustice'', ''WesternAnimation/TheLegendOfKorra'' and ''WesternAnimation/GreenLanternTheAnimatedSeries'' also have a lot of fandom crossover. This is thanks in no small part to the fact that one of the writers of GLTAS, Giancarlo Volpe, worked on the previous Avatar series and he has plugged his previous team's new show several times on Tumblr (and they return the favor.)
* There's also overlap between the two ''Avatar'' series and ''WesternAnimation/StarWarsTheCloneWars''; in addition to the aforementioned Giancarlo Volpe also previously worked on ''The Clone Wars'', ''Clone Wars''' supervising director Dave Filoni was a director on the first season of ''WesternAnimation/AvatarTheLastAirbender''. Voice actor Creator/DeeBradleyBaker has also cited his roles in both shows to be his favorite voice acting roles.
* Fans of Creator/GregWeisman shows seem to blend into one big fandom.
* ''WesternAnimation/YoungJustice'' and ''WesternAnimation/GreenLanternTheAnimatedSeries'' fans have banded together. As the two headliners of Cartoon Network's weekend morning "WesternAnimation/DCNation" block, they air in back-to-back time slots--and they were both subject to epic [[ScrewedByTheNetwork screwing by Cartoon Network]] when they were abruptly shelved about eight hours before airing their third episode after coming off summer hiatus. Fans want to see them back before January 2013. When both shows were canceled at the same time, the fandoms banded further together in support of both shows, using the FandomNickname "Symbiosi" (which, in ''Young Justice,'' is the Atlantean word for "together").
* While they do have a minor FandomRivalry, most ''WesternAnimation/AdventureTime'' fans are also ''WesternAnimation/RegularShow'', ''WesternAnimation/TheMarvelousMisadventuresOfFlapjack'', and/or ''WesternAnimation/StevenUniverse'' fans. This is thanks to the fact that the creator of Steven Universe, Rebecca Sugar, is a former ''Adventure Time'' writer who was known for writing fan favorite episodes like "[[TearJerker Simon and Marcy]]," and they both originally aired on Cartoon Network on Monday nights within the same hour (although ''Steven Universe'' has moved to Wednesdays).
* There's also considerable overlap between fans of ''WesternAnimation/GreenLanternTheAnimatedSeries'' and ''WesternAnimation/TeenageMutantNinjaTurtles2012'', as several fans of the former began to watch the latter after the DC Nation hiatus happened. [=TMNT2012=] also overlaps a lot with ''WesternAnimation/SuperRobotMonkeyTeamHyperforceGo!'' due to Ciro Neili producing the former and creating the later. He throws a lot of references to monkey team into TMNT and boy have the fans noticed.
* ''WesternAnimation/{{Gargoyles}}'' and ''Franchise/StarTrek'' fandoms get along excellently considering many ''Trek'' alumni have done character voices for the Disney series, especially Jonathon Frakes and Marina Sirtis as the major antagonists, David Xanatos and Demona respectively.
* ''WesternAnimation/AmericanDragonJakeLong, WesternAnimation/DannyPhantom'', and ''WesternAnimation/RandyCunninghamNinthGradeNinja'', all being {{Kid Hero}}es who WakeUpGoToSchoolSaveTheWorld and seem like they'd be good friends were they ever in the same universe, were given the crossover name "The Secret Trio" by fans on Website/{{Tumblr}}. This fanbase also has some overlap with the ''WesternAnimation/{{Detentionaire}}'' fanbase and ([[http://archiveofourown.org/works/7180583/chapters/16298627 thanks to]][[https://queenofhearts7378.tumblr.com the works of]] a writer known as [=QueenofHearts7378=]) the ''WesternAnimation/MiraculousLadybug'' fanbase.
* The fandoms of ''WesternAnimation/TotalDrama'', ''WesternAnimation/{{Sixteen}}'', and ''WesternAnimation/{{Stoked}}'' are all quite friendly with each other, due to all of them sharing similar tone and comedy, as well as being about Canadian teenagers. No surprise given that all three series are from [[Creator/FreshTV the same creators]]. ''WesternAnimation/{{Grojband}}'' can sometimes be included as well, although its vastly different tone and direction (due to being the brainchld of different people than the other 3) doesn't always make this the case.
* ''WesternAnimation/DannyPhantom, WesternAnimation/ParaNorman,'' and ''WesternAnimation/DudeThatsMyGhost'', because of the plot revolving around ghosts.
* Many ''WesternAnimation/SpongeBobSquarePants'' fans are usually friendly with the ''Adventure Time'' fans. Mostly because former writers from ''[=SpongeBob=]'' had worked on or are still currently working on ''Adventure Time''.
* There is a case with ''Adventure Time'' and ''WesternAnimation/PhineasAndFerb'', despite the two being completely different. This is because former writers had worked on the show. One of the creators (Dan Provenmire) was an occasional writer for ''[=SpongeBob=]'' (and a director for ''Family Guy'' episodes from Season 2-Season 5). It helps that both shows have an EnsembleDarkhorse character voiced by Olivia Olson (Marceline and Vanessa, respectively).
* Many ''WesternAnimation/HeyArnold'' fans are usually friendly with ''Rugrats'' fans as both shows are very character driven, aired on Nickelodeon around the same time, specialized in heartwarming moments and have similarities in characters. It's worth noting that Craig Bartlett is a former ''Rugrats'' writer, and left to create ''Hey Arnold''.
* Unlike their [[SpiritualSuccessor spiritual predecessors]], ''WesternAnimation/AmericanDad'' and ''WesternAnimation/{{Futurama}}'' fans are very friendly with each other because both shows are considered better than their predecessors, they're not as popular nor as successful as them, they have a similar style of humour and they both share some writers and producers. Both show's also underwent a relatively minor dose of SeasonalRot when they moved from Fox to their new respective channels.
* In the 2000s, many ''WesternAnimation/SpongeBobSquarePants'' and ''WesternAnimation/FamilyGuy'' fans liked both shows and were very friendly with each other because both started in the same year, were cancelled around the same time and revived in 2005, had similar jokes, an absurd tone, and characterisation and both suffered through a heavy dose of SeasonalRot around the same time for similar reasons. Not to mention they both replaced established franchises as flagship shows for their respective networks (''WesternAnimation/{{Rugrats}}'' and ''WesternAnimation/TheSimpsons'').
* Fans of ''WesternAnimation/LooneyTunes'' and ''WesternAnimation/TomAndJerry'' get along very well for the most part because of their large focus of slapstick and the fact that the studio behind ''Looney Tunes'', Creator/WarnerBros got the rights to ''Tom And Jerry'' through their ownership of the pre-1986 MGM library.
* The FiveManBand of [[TheEighties 1980s]] cartoons is often said to be composed of ''WesternAnimation/HeManAndTheMastersOfTheUniverse1983'', ''Anime/{{Voltron}}'', ''WesternAnimation/{{Thundercats}}'', ''WesternAnimation/TheTransformers'' and ''WesternAnimation/GIJoeARealAmericanHero''. And, if you talk to your typical children of the Eighties, you'll see it's for good reason.
* ''WesternAnimation/SpongeBobSquarePants'' and ''WesternAnimation/RegularShow'' as well, at least for the fact that the shows have similar characters.
* Just like The Secret Trio and Fanfic/RiseOfTheBraveTangledDragons, fanbases of certain animated shows- with KidHero stars battling the supernatural and strange -have united to create a composite team-up universe, featuring the Mystery Kids. The most frequent members of this team-up are the protagonists of WesternAnimation/GravityFalls, WesternAnimation/ParaNorman, WesternAnimation/{{Coraline}}, VideoGame/{{Psychonauts}}, and to a lesser extent, WesternAnimation/InvaderZim and WesternAnimation/DannyPhantom.
* ''WesternAnimation/GravityFalls'', ''WesternAnimation/StevenUniverse'', ''WesternAnimation/TheLegendOfKorra'', and ''WesternAnimation/OverTheGardenWall'', all of which have a very mature feel to them compared to most modern cartoons, and are all plot-driven. The similarity of GF and OTGW's respective sets of sibling protagonists combined with overall air of mystery, outdoorsiness and demonic presence also renders the two shows uniquely compatible. In a poke at the infamous trio of [[Series/{{Supernatural}} Super]][[Series/DoctorWho who]][[Series/{{Sherlock}} lock]], the crossover between ''Steven Universe,'' ''Gravity Falls'' and ''Over the Garden Wall'' has been dubbed Steven Falls Over.
* The fandoms of ''WesternAnimation/TeenTitans'' and ''WesternAnimation/DannyPhantom'' have been and still remain very friendly, with each show ''still'' having the other as their number one crossover on Fanfiction dot net over ten years later. Both shows came out around the same time and revolved around teenage superheroes and both were relatively lighthearted while still being able to go into some pretty dark territory, so it's not too surprising. Generally, if you were a fan of one, chances were you were also a fan of the other. In some circles, there was even a bit of a joke that Danny was the unofficial sixth Titan.
* Fans of ''WesternAnimation/GravityFalls'' are enjoying other modern animated shows that resemble ''Gravity Falls'' and have staff who are friends of Creator/AlexHirsch. Some shows include:
** ''WesternAnimation/StarVsTheForcesOfEvil''. Star Butterfly has been positively compared to Mabel for sharing Mabel's GenkiGirl personality, love of cute and colorful things like puppies and rainbows, and friendship with a savvy guy.
** ''WesternAnimation/DuckTales2017''. Not only is Alex Hirsch's girlfriend a director of the show in the first season, but the new Webby has been favorably compared to Mabel for her GenkiGirl personality and love of grappling hooks.
** ''WesternAnimation/RickAndMorty''. Not only is co-creator Creator/JustinRoiland a personal friends of Alex Hirsch, but ''Rick and Morty'' also has many references to ''Gravity Falls'' including a brief CrossoverPunchline [[https://www.youtube.com/watch?v=821TmxO95iE between the two shows]]. The fact that [[spoiler: Stanford is confirmed to have traveled through several dimensions]], a popular fanon has popped up that Rick and [[spoiler: Stanford]] were friends [[CrossoverShip if not more]]. The most common bit of fanon is that Rick Sanchez helped [[spoiler: Stanford]] obtain the Infinity-Sided Die, and smuggle it through inter-dimensional customs. %%The fact that Gr
** Fans of ''WesternAnimation/TheOwlHouse'' and ''WesternAnimation/{{Amphibia}}'', two other Creator/DisneyTelevisionAnimation shows, are friendly with both ''Gravity Falls'' fans and each other. Both shows were announced together, as well as having [[TrappedInAnotherWorld similar premises]] and being created by ''Gravity Falls'' alumni. The latter series even had Alex Hirsch voice frog versions of Grunkle Stan and Soos in a ''Gravity Falls'' homage.
* Fans of ''WesternAnimation/TheDragonPrince'' are on friendly terms with fans of other animated Netflix shows, like ''WesternAnimation/SheRaAndThePrincessesOfPower'' and ''WesternAnimation/VoltronLegendaryDefender''. (Though there's also quite a bit of FandomRivalry going on between those three in particular for reasons that shall not be gotten into on this page)
* ''WesternAnimation/InvaderZim'' and ''WesternAnimation/RickAndMorty'' fans get along since both sci-fi works involve heaping piles of BlackComedy aimed at exploring the meaningless of life. As with Alex Hirsch, Justin Roiland is good friends with Creator/JhonenVasquez with the two trading friendly jabs on social media.
* Thanks to Emman sharing ideas and stuff about them (like a hypothetical [[LighterAndSofter family-friendly]] approach to a ''Grand Theft Auto''/''Saint's Row'' game like ''LEGO City Undercover'' for the latter), the fans of ''WesternAnimation/TheLoudHouse'' and ''WesternAnimation/GoofTroop'' (especially with both [[WesternAnimation/AGoofyMovie Goofy]] WesternAnimation/AnExtremelyGoofyMovie Movies) are starting to be friends since they're both family-friendly animated comedies focusing on Family Relationships in Urban settings.
* Because of their {{moe}} cast, similar protagonists, and having some of the same crew[[note]]both are animated by Creator/GuruStudio, as well as Michela Luci voicing characters in both shows[[/note]], the fandoms of ''WesternAnimation/TrueAndTheRainbowKingdom'' and ''WesternAnimation/AbbyHatcher'' get along well.
* The fandom of ''WesternAnimation/KiddVideo'' is on good terms with that of ''WesternAnimation/{{Jem}}'', as both are 1980s cartoons focusing on bands.

[[folder:Music]]
* Although one band (Music/TheHollies) can be considered the shiniest of 60's sunshiny pop and (Music/ProcolHarum) can be considered, er, '''something else''', both bands and the their respective fandoms ''adore'' each other. No joke, the number of times that members of their band have helped out the others is legion. The friendship extends very much to the fans, and many times a Hollies fan is a Procol Harum fan and vice-versa. It helps that when Procol Harum had a date on Top Of The Pops in their earlier incarnation as The Paramounts, but had recently had all their gear nicked - guess who lent them theirs? And that the respective drummers, of said bands, Bobby Elliott and B.J. Wilson quickly became BFF's until Wilson's untimely death in 1990.
* Most jazz and classical music fans and players will like each other and go to each other's concerts. Classical fans also tend to like film scores, as they're usually done in a classical style.
* Metal bands which don't have a rivalry usually have some overlap.
** This is subverted by Music/{{Metallica}} and Music/{{Megadeth}}, whose fandoms have rivalries but have tons of shared fans who appreciate both bands. Both fanbases appreciate Mustaine's recordings with Metallica such as "No Life Till Leather", and in fact, the latter is how a lot of Metallica fans got into Megadeth.
* Gospel drummers and extreme metal drummers are often friendly and will look to each other for guidance; gospel drummers often look to extreme metal drummers for guidance on fluidity, stamina, and consistency at high tempos, while extreme metal drummers often look to gospel drummers for guidance on groove and syncopation, fill ideas and accents, and stick control.
* ''Franchise/KagerouProject'' and ''Music/EvilliousChronicles'' fandoms, to the point that most fans are fans of the other one involved. Mainly due to that both are epic RockOpera franchises (Evillious more than Kagerou Project) and use Vocaloid to create SugarWiki/AwesomeMusic. In Tumblr, Kagerou Project also shares many fans with other Vocaloid song series that have original characters, such as Shuuen no Shiori Project and Mikagura School Suite.
* Music/YukiKajiura and Music/YokoKanno have both this and FandomRivalry, depending upon the specific persons talking.
* Fans of the Music/FooFighters and Music/QueensOfTheStoneAge seem to get along well, since their front-men are involved in several projects together (Music/DaveGrohl has even guested on a few [=QotSA=] albums) along with being poster-boys for modern alternative rockers' habit of [[AttentionDeficitCreatorDisorder having too many damn side-projects]].
* Fans of Music/AmyWinehouse either overlap with due to their similar styles, or are friendly with fans of Creator/{{Adele}}, Music/LadyGaga and Music/PalomaFaith as the latter three have all regularly cited Amy as an influence. (The fact that they all did so when Amy was alive is especially appreciated by some of her fans, as it helped to counteract the negative press Amy was recieving at the time.)
* Fans of Music/QueensOfTheStoneAge and Music/NineInchNails are also quite friendly; it helps that the two bands have toured together, and performed together at the 2014 Grammys (with Music/DaveGrohl and [[Music/FleetwoodMac Lindsey Buckingham]], to boot).
* Fans of Music/RedHotChiliPeppers like Music/FooFighters because the bands are longtime friends. They toured together in 1999 and did some MTV specials together. RHCP fans who are fans of Dave Navarro's time in the band tend to like Music/JanesAddiction too, especially as Flea was briefly in the band.
* Music/{{Nightwish}} and Music/SonataArctica share a lot of fans, probably because the bands have toured together and the members are friends.
* Music/MrBTheGentlemanRhymer and Music/ProfessorElemental have both this and FandomRivalry, depending upon the persons talking.
* The fandoms of Music/ToriAmos, Music/{{Bjork}}, and Music/PJHarvey have a lot of people in common. It's probably because they all started their solo careers during the early '90s and [[http://www.yessaid.com/interviews/94-05Q.html were in an interview together.]]
* Music/{{Otep}}, Music/AmandaPalmer, and Music/EmilieAutumn. They're apparently all friends IRL. Also, to some extent, Music/CourtneyLove and Emilie Autumn (because Emilie was in Courtney's backing band), but that sometimes turns into FandomRivalry instead.
* Music/TupacShakur fans and Music/TheNotoriousBIG fans [[FandomRivalry used to not get along]]. Then, 1997 came around with both rappers having been murdered, and the two fandoms are now far more amicable on account of DeadArtistsAreBetter taking effect.
* Music/EnterShikari fans and Hadouken! fans. We don't know the exact reason, but it's nice to be friends, right?
* Also Music/TheQemists and Music/EnterShikari, due to the latter being featured and remixing many of the former's songs.
* Thanks to many world tours and live concerts made together, together with similar sounding music, Music/{{Goldfrapp}} and Music/{{Ladytron}} have a severe fandom overlap. Ladytron named themselves after a song by Music/RoxyMusic. Music/BrianEno, a former member of Roxy Music, is a fan of them. So, yeah, Ladytron's fandom is also in good terms with the ones of Roxy Music and of Brian Eno.
* MelodicDeathMetal bands Insomnium and Omnium Gatherum have very strong ties with each other, to the point where they both share a huge portion of their respective fan bases and the two bands are collectively known as Insomnium Gatherum. They also share a guitarist (Markus Vanhala) which has only served to increase their collective fanbase.
* Music/PinkFloyd fans tend to like Music/KateBush because Pink Floyd guitarist David Gilmour discovered her and has appeared on several of her albums.
* Music/DanBull fans tend to get along well with fans of LetsPlay/InTheLittleWood and to a lesser extent the LetsPlay/{{Yogscast}}, due to Dan recording tracks with both of them and getting along especially well with the former. Similarly, his fandom has developed a growing relationship with ''WebVideo/EpicRapBattlesOfHistory'' fans, in part due to Dan's [[KnightOfCerebus terrifying]] depiction of Jack the Ripper.
* Music/IcedEarth and Music/BlindGuardian fans have coexisted since the bands toured Germany together in the early 90s and became fast friends. When Jon Schaffer (of Iced Earth) and Hansi Kursch (of Blind Guardian) formed their side project Demons And Wizards and released two albums, which solidified the connection in the eyes of fans.
* Music/LanaDelRey fans are often also fans of Music/MarinaDiamandis. The artists themselves like each other's work and their shared love of satirical lyrics wins over many fans.
* The Music/WithinTemptation and Music/TarjaTurunen fandoms have been united by marriage ever since the release of "Paradise (What About Us)," a duet between Sharon Den Adel and Tarja, with a music video that pushed the HomoeroticSubtext through the roof. The [[PortmanteauCoupleName Sharja]] ship promptly took off, with the corresponding merger of the fans.
* Hudson Mohawke and Rustie fans get along quite swimmingly, possibly thanks to both being Scottish hip hop/trap producers that usually enter GenreBusting territory, and are subscribed to the same label - Warp Records[[note]]of Music/AphexTwin, Music/{{Autechre}}, and Music/BrianEno fame[[/note]]. It also helps the fact that they both appeared in a handful of games such as ''VideoGame/SleepingDogs'' and ''VideoGame/WatchDogs2''[[note]]Of which Hudson Mohawke composed the original score.[[/note]].
* In quite possibly one of the [[OddFriendship weirdest friendly fandoms]], UsefulNotes/{{Synthwave}} and HeavyMetal have a pretty close and friendly fandom to one another. This also goes into many of the artists of synthwave have backgrounds in metal such as Perturbator, Master Boot Record, Dance with the Dead, Scandroid, Hexenkraft, and the list goes on.
* Music/BillyBragg and Music/KirstyMacColl's fandoms overlap a lot. Not surprising since Bragg and [=MacColl=] were themselves friends and recurring collaborators, and [=MacColl=]'s cover of Bragg's "A New England" is a common [[GatewaySeries/{{Music}} gateway]] into both fandoms.
* Fans of one ProgressiveRock band, such as Music/PinkFloyd, Music/{{Yes}}, Music/KingCrimson, Music/JethroTull, Music/PorcupineTree, Music/{{Rush}}, Music/{{Genesis}}, etc., tend to be fans of other major bands in the genre. There's also quite a bit of overlap between the prog and metal fandoms, largely due to several major metal bands, including Music/DeepPurple, Music/BlackSabbath, Music/LedZeppelin and Music/{{Queen}} (all of whom are listed as [[http://www.progarchives.com/subgenre.asp?style=38 "prog related"]] on the website Prog Archives) dabbling in the genre, along with the classical influences on metal musicians, as well as Music/KingCrimson, Music/PinkFloyd, Music/{{Hawkwind}}, and Music/{{Rush}} heaving a heavier take on prog in turn. In the U.S., the two genres were both played on the same FM rock stations, which further encouraged the overlap between prog rock and metal fandom. And then there's the entire ProgressiveMetal subgenre that combines elements of both. Pink Floyd seems to be the primary exception to people that don't like progressive rock. The band's lyrical themes and lack of pretension seem to help.
* Music/{{Rammstein}} fans and Music/MarilynManson fans have a great deal of overlap due to them being dark IndustrialMetal bands with a penchant for creating controversy with their lyrical subject matter and imagery. It helps that Manson is friends with the band.
* Music/BabyMetal fans share a noticeable overlap with fans of Music/JudasPriest and Music/RobZombie thanks in part to the two's interactions with the band[[note]] Rob Halford joining the girls for covers of two of Priest's [[SignatureSong Signature Songs]] and Zombie defending the band from [[NoTrueScotsman metal gatekeepers]] bashing the girls online and praising them as one of the most energetic and engaging metal acts in years.[[/note]] and for the energetic and theatrical live shows they perform.
* Fans of {{country music}} stars Music/GarthBrooks and Music/TrishaYearwood are frequently one and the same, unsurprisingly so since the two have been regular collaborators and duet partners since the beginning of their careers and frequently toured together. To the glee of many of their fans, who had suspected mutual {{UST}} for years, they began dating around 2000 and married in 2005. Ever since, Trisha almost always does a brief set in the middle of Garth's concerts, usually including "She's In Love With The Boy", "Walkaway Joe", and "How Do I Live", three of her biggest hits. Go ahead, count how many of the fans in the audience know every single word. (It's most of them.)[[note]]Interestingly, Garth said upon meeting Trisha that he'd felt like [[LoveAtFirstSight he had just met his wife]] -- which was awkward since he'd already been married to his first wife for 13 months at the time. He and Sandy divorced in 2000, a year after Trisha divorced her second husband, Bobby Reynolds of The Mavericks. According to both, they're [[OneTrueLove the loves of each other's lives]].[[/note]]
* A ''[[OddFriendship really]]'' [[OddFriendship odd case of this]] was forged between the fanbases of experimental HipHop trio Music/DeathGrips and lighthearted IndiePop trio Music/KeroKeroBonito. Both projects are wildly different in tone -- Death Grips is known for being [[SensoryAbuse challenging, aggressive, and abrasive]], while KKB is known for being [[LighterAndSofter cute, down-to-earth, and generally upbeat]] -- and yet they've found similar overlap, partly because they've broadly found success through [[MemeticMutation meme culture]], with each having developed unique cult status among the internet, and partly because they ''are'' so diametrically-opposing. It also helps that in their own ways, both groups and their audiences have a sense of humor regarding their popularity -- case in point, [[https://www.youtube.com/watch?v=ZexwGDjxrpk KKB's live cover of Death Grips' "I've Seen Footage"]] provoked wildly enthusiastic AudienceParticipation.
* Music/{{Halestorm}} and Music/{{Lovebites}}, since Lovebites' name is a ShoutOut to a Halestorm song. Lovebites opened for Halestorm on their 2019 tour of Japan.
* Music/TaylorSwift fans tend to get on with (and overlap with) fans of Music/OliviaRodrigo, since Rodrigo is [[TheKnightsWhoSaySquee a big fan of Swift's]], citing her as one of her biggest inspirations and saying she'd love to write or record a song together. Swift, in turn, has shown Rodrigo a lot of support, sending her a personal letter of congratulations when she had her first hit, and letting her sample one of her songs for her debut album. Both women are singer-songwriters with intimate, narrative lyrics inspired from their own lives, who dabble in many different genres, so you can see why fans of one would like the other, and there's in general a mutual respect between the fandoms as well as the artists.
