* While there are many Minecraft roleplay series on the internet, there are four that ''really'' took off in the early 2020s; ''WebVideo/DreamSMP'', ''WebVideo/EmpiresSMP'', ''WebVideo/LifeSMP'' and the ''WebVideo/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 Life series fans when the Life series' 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, the Life series is very roleplay-focused but doesn't take itself too seriously (unless the content creator in question is Martyn LetsPlay/{{InTheLittleWood}}), 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]]

* 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/LifeSMP'' and the ''LetsPlay/HermitcraftServer'' (though Hermitcraft was already popular beforehand).

* 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/TheUnstoppableWasp'', ''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.
** They are also on good terms with their DC equivalent - fans of ''ComicBook/TeenTitans'' and ''ComicBook/YoungJustice''. And a significant part of ''Franchise/{{Batman}}'' fandom, the one that enjoys adventures of various Robins, Batgirls, and other teenage members of Bat-Family.
* Franchise/SpiderMan fans and ComicBook/{{Daredevil}} fans are on quite good terms. This is greatly helped by the fact that Spider-Man and Daredevil are very close friends in-universe (to the point that Daredevil is one of the only people Spider-Man trusts with his secret identity). This also extends to other New York-based, street-level heroes like the Heroes For Hire, Moon Knight, She-Hulk, and Darkhawk.
* Spider-Man fans tend to get along with ComicBook/{{Deadpool}} fans, partially due to both characters being well-known for snarky humor. It helps that the two often have really good crossovers.

* Fans of Matt Fraction and Kelly Sue [=DeConnick=] are extremely close with each other, which is rather fitting given that the two are married in RealLife.
* ''Franchise/{{Superman}}'' fans and Franchise/SpiderMan fans tend to get along well, despite the whole DC vs Marvel thing, perhaps because the two heroes are so similar that you can't really like one and hate the other. Doesn't hurt that the two have had three crossovers to themselves and two company-wide crossovers where they both appeared. The two fandoms became the other's sole confidant when the two franchises started facing the same problems.

* 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 have 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.
* ''Franchise/TeenTitans'' fans and ''Franchise/XMen'' fans do tend to get along well. Doesn't hurt that their respective [[MyRealDaddy daddies]] -- Creator/MarvWolfman and Creator/ChrisClaremont -- have spoken favourably of each other's run on the respective teams, especially that both had a crossover to themselves during the Eighties.

* ''Webcomic/ScandinaviaAndTheWorld'' and ''Webcomic/Polandball''

* The two gay male food historians of Youtube: Creator/BDylanHollis and ''WebVideo/TastingHistoryWithMaxMiller'', have a huge overlap in viewers, despite being pretty much the antithesis of each other. Max is more professional in presentation, releases videos on a regular schedule, and the videos are longer and more informative about the history of the featured dish. He also covers a broader scope of history, ranging from the dawn of civilization to the 1950's, and from cultures all around the world. But the actual dishes can be complicated to prepare and often have ingredients that are expensive and/or hard to find. Dylan, on the other hand, has shorter videos as they're primarily made for Tik[==]Tok (though he has a few longer ones on Youtube) and they're more comedic in tone, but he's less committed to a strict release schedule than Max. His scope is limited to (mostly) American dishes from the Civil War to the 1980's, but they're more accessible to the average viewer as most of his recipes come from old homemaking magazines and community cookbooks. In any case, two are constantly mentioned by fans in the comments of each other's videos, begging for a collaboration.

* The two gay male food historians of Youtube: Creator/BDylanHollis and ''WebVideo/TastingHistoryWithMaxMiller'', have aa ''lot'' of overlap in viewers.

The opposite of FandomRivalry. Two (or more) fandoms have a lot of overlap because of shared talent (sometimes the result of a ProductionPosse), because of similar subject matter, because they happened to air at about the same time, or for no real reason at all - they just like each other. Often people get into one fandom and are encouraged by this relationship to get into the other.

[[folder:Films -- Animation]]
* Compared to the television animation community, the animated film community doesn't have borders between Main/WesternAnimation and {{Anime}}.
* The fandoms of ''WesternAnimation/TheSecretOfNIMH'', ''WesternAnimation/AnAmericanTail'' and ''WesternAnimation/TheGreatMouseDetective'' all seem to get along with one another pretty well (as long as the topic of which film was better is avoided), with a lot of crossover fan-art and fan-fiction existing between them.
* Largely due to releasing around the same time and the respective protagonists' ages being close together, overlapping fandoms of the ''WesternAnimation/RiseOfTheGuardians'', ''WesternAnimation/{{Brave}}'', ''WesternAnimation/{{Tangled}}'' and ''Franchise/HowToTrainYourDragon'' movies became ''Fanfic/RiseOfTheBraveTangledDragons''. Fans of ''Franchise/{{Frozen}}'' are also on good terms with fans of these movies, probably because of the [[WesternAnimation/{{Tangled}} Rapunzel-Flynn cameo]] and Elsa's [[AnIcePerson similar powers]] to [[WesternAnimation/RiseOfTheGuardians Jack Frost]] ([[CrossoverShip in fact, the two are often shipped together]])
* ''WesternAnimation/BigHero6'' fans with the Franchise/MarvelCinematicUniverse fans. They have come up with possible crossovers that involve Hiro joining S.H.I.E.L.D. or Baymax greeting the Avengers.
* While most Franchise/DisneyAnimatedCanon fandoms get along, three in particular often intersect and get along ''especially'' well. "Four Seasons" is the FanNickname for ''Franchise/{{Frozen}}'', ''WesternAnimation/{{Tangled}}'', and ''WesternAnimation/{{Brave}}'' together. The name comes from the main girls being seen as representing seasons: Rapunzel (or Anna) is spring, Anna (or Rapunzel) is summer, Merida is autumn, and Elsa is winter.
* ''WesternAnimation/RiseOfTheGuardians'', ''Franchise/HowToTrainYourDragon'', and ''WesternAnimation/TheCroods'' fans tend to get along well primarily because said fans have a particularly strong liking to the central teenage, male character of each film ([[AnIcePerson Jack Frost]], [[DragonRider Hiccup Haddock]], and [[TheSmartGuy Guy Crood]], respectively).
* ''WesternAnimation/TurningRed'':
** With ''WesternAnimation/TheBadGuys2022'', as both movies came out in 2022, focus on [[UsefulNotes/FurryFandom anthromorphic animals]] and have similarly stylized, colorful animation.
** ''WesternAnimation/BrotherBear'' fans are likely to be on board as both films have protagonists who gain the ability to transform into ursine forms and learn to like their new forms with their families also learning to appreciate them too.
** ''WesternAnimation/{{Encanto}}'' fans also like to include Mirabel in the mix. The relation between the two grew stronger when it was revealed that [[spoiler:one of the themes was GenerationalTrauma, with [[CallingTheOldManOut Mei Lee calling out her mom for her high expectations]] and emotionally supporting her after learning of her past trauma, just like Mirabel did with Abuela Alma]].
** With ''Franchise/KungFuPanda'' potentially, due to the shared theme of anthropomorphic animals with prodigious strength, agility and mystical abilities. Both stories also have protagonists who pursue their dreams against all doubts.
** With ''WesternAnimation/{{Luca}}'', as both films involve young protagonists who can shapeshift and have to hide their non-human forms among humans. This often leads to fan works of Mei meeting Luca and Alberto, regardless of the disparate time periods.
** Surprisingly, with ''WesternAnimation/ParaNorman'' fans as well. Not only because both Norman and Mei deal with something they consider a "curse" (Norman his ability to see and talk with ghosts and Mei her panda transformation), but both must face down disapproving parents (their father and mother respectively), and said "curses" are vital in their respective climaxes, which ultimately end with [[spoiler:going into the spirit realm to calm down the antagonist. Mei meets the younger form of her mother in the spirit realm and helps her come to terms with herself, similar to how Norman talked down Agatha.]]

[[folder:Films -- Live-Action]]
* ''Film/{{Hulk}}'' and ''Film/{{Logan}}'' surprisingly get along because of the similar tone and dark uniqueness of both Marvel-related films. It also helps that both focus much more on character development.
* The fandom of the ''Film/HarryPotter'' films overlaps with that of Tim Burton's film of ''Film/SweeneyToddTheDemonBarberOfFleetStreet'' due to the many shared actors in both films. Comments on Website/YouTube clips of the latter often jokingly refer to [[Creator/AlanRickman Judge Turpin]], [[Creator/HelenaBonhamCarter Mrs. Lovett]], and [[Creator/TimothySpall Beadle Bamford]] as Snape, Bellatrix, and Pettigrew, respectively.
* ''Franchise/EvilDead'', ''Franchise/ANightmareOnElmStreet'', and ''Franchise/FridayThe13th''. In addition to being three of the biggest horror franchises to come out of TheEighties, its creators were fans of each other's work and referenced each other at least once in their respective films. All three had enough fans to warrant not only [[Film/FreddyVsJason a cinematic crossover between Freddy and Jason]], but also [[ComicBook/FreddyVsJasonVsAsh a comic book crossover between all three]].
* While ''Franchise/{{Alien}}'' and ''Franchise/{{Predator}}'' fans getting along was expected given [[Franchise/AlienVsPredator the series' famous crossover]], there's also an overlap with ''Franchise/{{Terminator}}'', as all were violent 80s sci-fi franchises with some shared cast and crew.
* Giant monster fans of multiple franchises tend to get along very well, despite studio rivalries. ''Film/{{Gamera}}'' fans and ''Franchise/{{Godzilla}}'' fans are prime examples. Fansites to one nearly always include the other and crossover fan-works are extremely common. In that vein, there are plenty of people who love ''Film/PacificRim'' and ''Film/Godzilla2014'' for being big budget giant monster movies in spite of their different tones (and there is a rivalry because of that).
* A surprising OddFriendship has formed between the ''Film/Deadpool2016'' and ''Film/WonderWoman2017'' fandoms even though the heroes are complete polar opposites. It may be because Deadpool's actor Creator/RyanReynolds himself offered his heartfelt congratulations to ''Wonder Woman'' when it outgrossed ''Deadpool''. This cordial relationship continued with ''Film/Deadpool2'' making some sly shout-outs to ''Wonder Woman'' that Gal Gadot personally found endearing and funny. It also helps that Creator/GailSimone previously wrote for both of the characters' comics.
* ''Franchise/MarvelCinematicUniverse'':
** The MCU fandom gets along better with the fandom of ''Film/{{Deadpool|2016}}'' than with those of [[Film/TheAmazingSpiderMan previous]] [[Film/XMenDaysOfFuturePast post-Avengers]] [[Film/FantasticFour2015 Marvel efforts]] by other studios mostly because Deadpool's black comedy and graphic violence would be better off in its own universe than in the LighterAndSofter MCU, as well as the entire aspect of Creator/RyanReynolds DoingItForTheArt and (very successfully) pushing his vision of an accurate adaptation of Deadpool onto the big screen. It helps that ''Deadpool'' made a few affectionate shout-outs to the MCU, with MCU producer Kevin Feige offering his consultation and approval to the production crew. This has only gotten stronger with Disney's acquisition of ''Deadpool'' studio Creator/TwentiethCenturyFox, as the buyout addresses any potential DuelingWorks animosity whether or not ''Deadpool'' and [[Film/Deadpool2 its sequel]] will be {{retcon}}ned or integrated into the MCU.
** Surprisingly, MCU fans are on much better terms with ''Film/MonsterVerse'' fans than ''Franchise/DCExtendedUniverse'' fans. This may be due to both franchises sharing the same actors such as Creator/AaronTaylorJohnson and Creator/ElizabethOlsen for ''Film/Godzilla2014'' and Creator/TomHiddleston, Creator/BrieLarson and Creator/SamuelLJackson for ''Film/KongSkullIsland''. It could also be the fact that Marvel had produced a Godzilla comic book line in the '70s, therefore some Marvel fans consider Godzilla an honorary Marvel character. Regardless, both fandoms like each other so much so that both fandoms would like to see a crossover with The Avengers fighting Godzilla or other famous Kaiju.
** While there ''was'' some rivalry going on, ''Film/CaptainMarvel2019'' fans generally do hold a cordial relationship with ''Wonder Woman'' and ''Film/Shazam2019'' fans. For the former, it was helped by their respective fanbases [[EnemyMine uniting against]] their GirlShowGhetto detractors, as well as the two movies' cast members and directors being supportive of one another (''Wonder Woman'' director Creator/PattyJenkins voiced her enthusiasm for the MCU superheroine movie, while ''Captain Marvel'' star Creator/BrieLarson has been open about being a big Wonder Woman fangirl growing up and even [[TearsOfJoy cried in happiness]] when she saw the movie). For the latter, that positive relationship was helped by ''Shazam'' director Creator/DavidFSandberg and star Creator/ZacharyLevi denouncing trolls trying to drag ''Captain Marvel'' down in favor of ''Shazam'', a sentiment that was repaid for with ''Captain Marvel'' fans encouraging others to go see and support ''Shazam''.
** ''Film/{{Black Panther|2018}}'' fans and ''Film/{{Aquaman|2018}}'' fans get along well with each other since they are the first films in their respective franchises to have both non-white leads and directors, giving the superhero movie genre some much-needed diversity. The fact that DCEU fans [[https://screenrant.com/black-panther-movie-dc-fans-raise-money/ raised money]] for black kids from impoverished backgrounds to see ''Black Panther'' in a nice theater makes it clear that some things (like giving kids of all backgrounds a hero they can see themselves in) override petty rivalries.
** Similar to the above fandom friendship, ''Black Panther'' and ''Film/WonderWoman2017'' fans tend to have a very cordial relationship since both films star a superhero from an often underrpresented group and proved the supposed "beliefs" that black and/or female superheroes don't sell well ''very'' wrong.
** While Star Wars fans as a whole, especially those into the sequels, have a rather massive rivalry with MCU fans for various reasons, the prequel fans and MCU fans have started to get along rather well. It helps that sequel era fans and prequel era fans have their own internal rivalry and "the enemy of my enemy" after all.
** ''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 in the years prior, 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.
* Several fans of ''Film/{{Willow}}'' have become fans of ''Film/{{Solo}}'', and several people who liked ''Film/{{Solo}}'' have discovered ''Film/{{Willow}},'' thanks to both movies being [[CultClassic oddball]] Lucasfilm productions that both happened to be directed by Creator/RonHoward. Especially since the idea of a sequel/follow-up to ''Willow'' floated around after that, eventually materializing into a Creator/DisneyPlus series project.
* Fans of Creator/HeathLedger's [[Film/TheDarkKnight Joker]] and Creator/JoaquinPhoenix's [[Film/Joker2019 Joker]] get along very well, helped by Ledger and Phoenix having been good friends before the former's untimely death and for both of them winning Oscars for their respective performances. However, it is frowned upon to compare the two, as they're playing very different interpretations of the same character.
* Due to the three films' shared satire/critique of the elite and wealthy as well as all of them coming out in 2022, fans of ''Film/TheMenu'', ''Film/TriangleOfSadness'', and ''Film/GlassOnion'' get along very well. So much so that the three movies have been dubbed by some as "2022's Eat the Rich Trilogy".

[[folder:Literature]]
* Creator/TerryPratchett fans and Creator/NeilGaiman fans, because of their collaboration on ''Literature/GoodOmens''.
** And Creator/DouglasAdams fans overlap with both!
** And Creator/DouglasAdams fans lap over with ''Series/DoctorWho'' fans, since Adams was a writer and producer for the show, and one of his books, ''Literature/DirkGentlysHolisticDetectiveAgency'', was basically a rewrite of an unused DW script. Then Creator/NeilGaiman wrote two ''Doctor Who'' episodes, showing his love for the series, cementing these relationships.
** Between 2005 and 2006, there was a major crash on a Creator/WilliamGibson message board, so the members of that board were essentially invited to hang out on the official Gaiman forum until the site issues were resolved. They did, and the two fandoms got along so well that some members wound up participating on both boards for years.
** There's also a lot of overlap between fans of Pratchett and Creator/RobertRankin, on the grounds that his style is somewhat reminiscent of what [[FanNickname Pterry]]'s might have been like if [[ThisIsYourPremiseOnDrugs he'd got into much, much harder stuff than scrumpy]].
* ''Literature/TheChroniclesOfNarnia'' and ''Literature/TheLordOfTheRings'', due to both being fantasy written by authors who were close personal friends and both had an intensely Christian worldview (which influenced their works to varying degrees). Interestingly enough, Tolkien, despite his friendship with Lewis, has stated his dislike for Narnia calling it an illogical pastiche of mythical elements.
* Many ''Literature/DiaryOfAWimpyKid'' fans tend to be fans of ''Literature/CaptainUnderpants'' due to both series being at the height of their popularity at the time as well as having similar art-styles, characters and humor. The fact that the former came out during the latter's 2006-2012 hiatus definitely helps (since it gives ''Captain Underpants'' fans something to pass the time with).
* Back when both series were originally coming out, the ''Literature/{{Sweep}}'' and ''Literature/CircleOfThree'' fandoms fed into each other, since they were both YA series about teenage witches coming out around the same time. There were many [=GeoCities=] sites dedicated to both.
* Fans of hard science fiction writers and series like Larry Niven, Robert Reed, David Brin, and Peter Watts tend to be pretty close-knit with each other.
* ''Literature/NineteenEightyFour'' and ''Literature/{{Fahrenheit 451}}'' readers, due to both novels revolving around {{dystopia}}n governments that censor material, being published relatively close in time to each other, and featuring elements that have become part of many real-life governments.
* ''Literature/WarriorCats'' and ''Literature/WingsOfFire'', due to the author Tui Sutherland being a member of Creator/ErinHunter and creating ''Wings Of Fire''.
** A variation: most ''Literature/TheBookOfTheNamed'' readers are former ''Literature/WarriorCats'' fans who wanted to read a more mature story about [[{{Xenofiction}} talking felines]]. See also ''Literature/TailchasersSong''.
** ''Literature/WarriorCats'' and ''Literature/GuardiansOfGaHoole'', both being {{Xenofiction}} with fantasy elements aimed at the same age group.
** ''Literature/WarriorCats'' fans tend to have good relations with fans of fellow {{Xenofiction}} novels ''Literature/{{Redwall}}'' and ''Literature/{{Silverwing}}''.
* ''Literature/FiftyShadesOfGrey'' and older ''Literature/{{Twilight}}'' fans naturally get along, considering the former started life as the latter's fanfiction.
* There's a ton of overlap between fans of ''Literature/TheRavenCycle'' and ''Literature/AllForTheGame'', and even a fair amount of crossover fan work despite the relative differences of the two series.
* There's a lot of crossover between the fandoms of ''Literature/OmniscientReadersViewpoint'', ''Literature/TrashOfTheCountsFamily'', and ''Literature/TheSClassesThatIRaised'' because of similarities in genre, setting, and themes.
[[/folder]]

[[folder:Podcasts]]
* ''Podcast/KakosIndustries'' attracted a large number of ''Podcast/WelcomeToNightVale'' fans due to their similar formatting and mix of horror and SurrealHumor. Emerging {{Fanon}} theory is that Kakos is somehow linked to fellow EvilInc company Strex Corp.
[[/folder]]

* Largely due to releasing around the same time and the respective protagonists' ages being close together, overlapping fandoms of the ''WesternAnimation/RiseOfTheGuardians'', ''WesternAnimation/{{Brave}}'', ''WesternAnimation/{{Tangled}}'' and ''WesternAnimation/HowToTrainYourDragon'' movies became ''Fanfic/RiseOfTheBraveTangledDragons''. Fans of ''WesternAnimation/{{Frozen|2013}}'' are also on good terms with fans of these movies, probably because of the [[WesternAnimation/{{Tangled}} Rapunzel-Flynn cameo]] and Elsa's [[AnIcePerson similar powers]] to [[WesternAnimation/RiseOfTheGuardians Jack Frost]] ([[CrossoverShip in fact, the two are often shipped together]])

* While most Franchise/DisneyAnimatedCanon fandoms get along, three in particular often intersect and get along ''especially'' well. "Four Seasons" is the FanNickname for ''WesternAnimation/{{Frozen|2013}}'', ''WesternAnimation/{{Tangled}}'', and ''WesternAnimation/{{Brave}}'' together.

* 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/LifeSMP'' 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]]

* Wrestling/ProWrestlingZero1 and Wrestling/ProWrestlingNOAH initially had, competitive if not quite hostile fan bases, who tended to be adamant about which one was better as it looked like one of the two could legitimately become the most successful promotion in Japan. NOAH had a more "real sport" presentation but otherwise more theatrical matches, while Zero 1's in-ring action tended to more grounded everything else about it [[WeirdJapaneseThing was anything but]]... but with the peaks of both companies passing, the fan bases grew a lot closer. Zero 1, in general, indirectly encourages this sort of thing with its atypical cosmopolitan atmosphere, resulting in a fair bit of crossover with fans of Wrestling/DramaticDreamTeam, FMW, GAEA/Marvelous, CMLL and even Action Zone Wrestling in Hawaii. Even if they don't actively follow it, there are a lot of fans familiar with and fond of Zero 1.

** With ''WesternAnimation/TheBadGuys'', as both movies came out in 2022, focus on [[UsefulNotes/FurryFandom anthromorphic animals]] and have similarly stylized, colorful animation.

* This is taken UpToEleven in Brazilian association football, where, back in The80s 2 big torcidas organizadas (basically the same as hooligan firms) groups were formed. Those were União Punho Cruzado, with supporters of Flamengo, Cruzeiro, São Paulo, Sport Recife and Internacional, along with foreign ally LDU Quito, and União Dedo Pro Alto (literally the middle finger), with supporters of Vasco da Gama, Atletico Mineiro, Palmeiras, Bahia and Grêmio.
