Friendly Fandoms

The opposite of Fandom Rivalry. Two (or more) fandoms have a lot of overlap because of shared talent (sometimes the result of a Production Posse), 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.


Examples:

    Inter-Media/General 
  • In spite of the oft-hyped tensions between fans of Star Wars and those of Star Trek, truth is, the two sagas are so different, they don't really step on each other's toes. And in the modern times, true pop-culture geeks understand the economics of how TV and film projects get the go-ahead or not, therefore, fans of both works tend to look at the others' success as being a boost to their own favorite.
  • Stranger Things fans tend to get on quite well with fans of It (2017) due to both being stories about child characters set in the eighties and both having Finn Wolfhard in the cast.
  • Due South and Hard Core Logo. Because Canadians have to stick together, eh?
  • There's a great deal of overlap, probably unsurprisingly, between fans of Horatio Hornblower, Aubrey-Maturin, Pirates of the Caribbean, Temeraire and Jane Austen. It's more generally known as the Age Of Sail fandom.
  • My Little Pony: Friendship Is Magic:
    • Considering it's a show that teaches the magic of friendship, it makes sense why the fandom is on good terms with many others.
    • Doctor Who and MLP:FIM have developed some harmony between each other, mostly due to a fan-favorite minor character in the latter show reminding everybody of the Tenth Doctor.
    • The Bronies have developed friendships with a lot of fandoms in general, but it seems that the biggest one is the friendship between the Valve fandom. Mostly because the Valve games helped to spread the word on its early days, specially Team Fortress 2. Many Team Fortress 2 crossovers have been made, to the point of having designed characters from the show to represent the characters from the game in the crossovers, and many references to the game in the pony-related videos in YouTube. Also helped by the steadily growing number pony models for Garry's Mod and Source Filmmaker, which are used to create most TF2 fanvids.
    • TF2 and MLP fans get along for the most part, but there are the Vocal Minorities who love TF2 and despise MLP, and those who worship MLP and detest TF2.
    • One notable fandom overlap with MLP is Dwarf Fortress. It seems odd, but just about a third of the DF community is a brony. It helps that, when a pony conversion mod was made, the ponies proved themselves to be quite capable of dealing with the usual dwarven troubles, surpassing the dorfs themselves at times.
    • Bronies and Sonic the Hedgehog fans get along quite well. Fan art often emphasizes the similarities between characters of the two series (i.e., Sonic and Rainbow Dash, Knuckles and Applejack, and so on). Most fans at least. The Vocal Minorities of both fandoms seem to unreasonably hate each other for no reason, leading to Equestria Daily banning Sonic-related content.
    • Homestuck sees a good deal of camaraderie with Bronies, partially due to both franchises tending to dominate attention across the internet and being resultant. Naturally, this also causes some strife. The fact that fan favorite badass Dirk Strider is a Brony serves to smooth out the edges.
    • Bronies also tend to get along with Blood and Ice Cream Trilogy fans, most likely inspired by Edgar Wright responding favorably to a fan-made crossover of My Little Pony and Scott Pilgrim vs. The World.
    • Unsurprisingly, many Bronies are also associated with the Furry Fandom, likely due to both fandoms being centered around cartoon animals and producing a large amount of fan art. This topic has been controversial in the past, and that's all there is to be said about the subject.
    • Quite a few PAW Patrol fans also happen to be bronies.
    • Given the nature of the fandom, the bronies tend to cross ponies with everything at some point, even leading to getting a rule of their own added to the Rules of the Internet (Rule 85) and that rule being accepted in the standard list now. That being said, you would be hard-pressed to find any fandom the bronies as a whole truly do not like. As for vice versa, your mileage may vary.
  • The Mystery Science Theater 3000 fandom has a large crossover percentage with Transformers fans. This gives the Transformers fandom a healthy dose of self-awareness about itself bordering on Self-Deprecation. It's no accident that the ironic use of Ruined Forever originated with Transformers fans; in return, Dull Surprise became a meme regarding the poor artwork of Pat Lee. The MST3K influence is very heavily felt on the Wiki/TFWiki.
  • You can expect many Touhou fans to be Puella Magi Madoka Magica fans and vice versa. Especially if they cosplay.
    • The Touhou fandom is also very friendly with the Vocaloid fandom, since both are series popularized by fan-submitted content.
  • There is a lot of overlap between fans of the video game Titanfall and the anime and manga series Attack on Titan, both of which center on conflicts between massive "Titans" and infantry with equipment to enhance mobility.
  • Rival fandoms who team up with each other to fight a bigger Rival Fandom can develop into this over time. The rivalry between Mario and Sonic has developed into this, for example.
    • Sega has also stated that once they couldn't afford to make consoles anymore they preferred making games for the GameCube because of the similarities between the Nintendo and Sega fandoms. It's no wonder that those fanbases love to team up against the Sony and Microsoft fandoms.
  • Many AlternateHistory.com users are fans of Code Geass, due to the series being set in an alternate history. A good deal of timelines on the site are also Code Geass fanfics.
  • With the advent of the new Doctor Who, there seems to be a deliberate effort underway to unite Who fans and Star Trek fans. Besides little things like Patrick Stewart being a big Who fan and Freema Agyeman and John Barrowman being Niners, there's also Stewart and David Tennant appearing in an OldVic production of Hamlet. And now, there's an official crossover comic from IDW publishing pitting the Enterprise-D and the 11th Doctor against a super-villain alliance between the Borg and Cybermen.
  • A great deal of Hellsing fans are well-versed in the Darker and Edgier reboot of the Castlevania franchise. While both universes have a character named Alucard, it's the seemliness between Hellsing's Alucard and Castlevania's Dracula that unites them. note 
  • Sherlock and Cabin Pressure, due to the shared presence of Benedict Cumberbatch.
  • Western Animation fans and Anime fans are beginning to get along pretty well. Several Western Animation characters are even drawn in Anime style on DeviantArt, most notably the South Park characters (the latter probably helped by the fact that Trey Parker, one of the creators of the aforementioned show, is a fan of anime).
  • There are several Homestar Runner/Penny Arcade crossover artworks and fanfictions on DeviantArt, especially thanks to Poker Night at the Inventory.
  • Fans of Batman: The Animated Series tend to easily become fans of the Batman: Arkham Series, since Paul Dini, head writer of BTAS, wrote for the Arkham series, and many VAs from the DCAU returned to voice their respective characters, notably Kevin Conroy as Batman and Mark Hamill as The Joker. Quite notable in that most fandoms of each Batman adaptation tend to be venomous towards each other.
  • If you're a fan of The Elder Scrolls V: Skyrim, chances are you're also a fan of A Song of Ice and Fire, particularly HBO's Game of Thrones series. A sizable portion of Skyrim's library of Game Mods is devoted to adding Game of Thrones-related content to the game — there is more than one mod that adds a fully-modeled Longclaw, for example.
  • There's also some overlap between Game of Thrones fans and players of Crusader Kings II, since the latter is essentially a medieval politics simulator. There's a Game of Thrones-themed Game Mod which is reasonably popular, which has in turn inspired a number of After-Action Report fan fictions. Now that there is also a mod for Crusader Kings II that allows you to play as one of the rulers in Tamriel, it seems the cycle is now complete.
  • With the release of The Avengers, the Tumblr-born SuperWho to SuperWhoLock pattern mentioned in the TV section continued, and now we have SuperWhoAvengeLock. Any and all smaller combos of the four show up too.
  • Since, in Japan, Pretty Cure airs in the same kids block as Super Sentai and Kamen Rider, they're going to be grouped together in a lot of fans' minds anyway, but it has a special relationship in 2012 due to the Japanese fandom almost unanimously deciding that Yayoi is a Toku fan, and, like most fan things, exaggerating it. To wonderful effect.
  • Many Axis Powers Hetalia fans also like the lesser-known Scandinavia and the World, due to the similar premises of the series.
  • There is quite a bit of overlap between the fandoms of Discworld and Slayers.
  • It seems there are a fair few My Little Pony fans (as in, fans of the franchise in general, not Friendship is Magic in particular) who are also Pokémon fans, perhaps due to both of them being child-oriented and collecting-oriented.
  • Hell, a fair chunk of tumblr is dedicated to giant love piles of fandom friendship. Excellently exemplified by this post.
  • Fans of Comic Books, collectible card games like Magic: The Gathering, tabletop wargames like Warhammer 40,000, and roleplaying games like Dungeons & Dragons see considerable overlap, since all are often found under the same roof.
  • Many fans of Les Misérables (2012), followed Aaron Tveit and George Blagden, the actors who portrayed fan favorite characters Enjolras and Grantaire, to their next projects, Graceland and Vikings. This led to a lot of mingling and friendship between the three fandoms.
  • Ultra Series fans and Godzilla's fandom tend to overlap a fair bit, thanks to their shared love of kaiju and special effects wizard's Eiji Tsuburaya's influential involvement in the early days of both franchises.
  • Pacific Rim:
  • Gravity Falls, ParaNorman, Coraline, and Psychonauts form what is collectively called "Mystery Kids". Gravity Falls is also commonly seen with Welcome to Night Vale and Twin Peaks.
  • The Nippon Ichi and When They Cry fanbase, namely due to the former being big players in movements to localize the later.
  • Fans of post cancellation Family Guy and The Big Bang Theory are often friendly with each other because both shows rely on pop culture references for jokes and have very similar humor. Of course, this would would also lead to include Friendly Hatedoms of both.
  • The World of Tanks and Girls und Panzer fandoms are essentially the same people, and both the game and the show became runaway Sleeper Hits by drawing on each other's success, particularly in Japan where the latter's cult following started.
  • League of Legends and anime fans in general with some overlap of Fandom Rivalry. It also helps to note that there are a lot of anime-like cliches in the game, the Riot staff members being anime geeks themselves, and the voice actors who voiced champions in this game also work in the anime dubs themselves.
  • Homestuck:
    • Homestuck and Axis Powers Hetalia used to have quite the rivalry, but after realizing that the two fandoms overlap a lot, they've made up and declared themselves each others Moirails. Hetalia has also struck a cord with some AlternateHistory.com users as well, with all the frequent Alternate Universe Fic opportunities.
    • Homestuck and Dangan Ronpa also have a decent overlap, which makes sense since both series have a tendency to kill off their Loads and Loads of Characters after fleshing them out and giving them unique personalities, and both series involve teens having to deal with The End of the World as We Know It in different ways. It's also thought the fans of the former latched onto the latter because the former is on hiatus leading up to the final act.
    • Fans of Homestuck tend to overlap with fans of Undertale a great deal, due to both of them involving the musical genius of Toby Fox.
    • Also for a short while with the OFF fandom, though it faded into flavor of the month territory.
    • 17776 deserves special mention, as upon becoming popular it was instantly compared to Homestuck, and therefore the fandoms of both overlapped heavily.
    • It'd actually be quicker to list the fandoms Homestuck DOESN'T overlap with.
  • Hannibal and Welcome to Night Vale have so many fans in common that co-producer Jeffrey Cranor attributed the spike in Night Vale's popularity on Tumblr to the simultaneous rise of the Fannibals. It's easy to see what they have in common: both shows are horror-oriented and surreal, with Creepy Good protagonists and a very morbid sense of humour, and while Hannibal is a much more serious show, its fandom tends to be light-hearted and irreverent in a way that doesn't clash with the Night Vale fandom's sense of whimsy.
  • Since Wicked and Frozen have similar themes, share Idina Menzel playing a main character, and have an "I Am Becoming" Song as their Signature Song, fandoms between the two overlap a lot.
    • There's also some overlap with the anime Kill la Kill. Both feature, anti-respectively, an Ice Queen and an Ice Person (who happens to be a queen) with fitting amounts of blue in their character designs, stepping out of a hidebound, tradition-controlled isolation, and both feature two formerly close sisters brought back together. It certainly helps that Frozen premiered during Kill's run on TV.
    • In addition, the fandom of Captain America: The Winter Soldier also tends to overlap with Frozen's fandom, with the conflict between the two sisters being compared to that of the one between Steve Rogers and Winter Soldier/ Bucky Barnes, to the point that it is common for fans to draw Anna and Elsa as the former two.
    • Frozen and Tangled is more common than any other princess movie crossover. A large portion of it has to do with a small Rapunzel cameo at the start of the film.
  • Fans of Fighting Games, particularly Street Fighter, also tend to love Dragon Ball. Considering both predominantly feature a bunch of martial artists firing off ki blasts, it's really no surprise.
  • Curiously enough, there seems to be a budding overlap between Kantai Collection and Axis Powers Hetalia. Which makes sense given that both series include personified beings as well as involve World War II and history to some degree.
  • The Sonic the Hedgehog fandom may have a notorious vocal minority that seems to dislike anything that isn't Sonic (and is remarkably picky about Sonic), but even they get along well with Batman fans. This is most likely because these Sonic fans grew up during The '90s, whose perception of Sonic was shaped tremendously by Sonic SatAM (the Saturday morning series simply titled Sonic the Hedgehog and Archie Comics' Sonic the Hedgehog, both of which were incredibly dark series for their target audiences), and Batman: The Animated Series and Tim Burton's Batman had a similarly dark and bleak feel.
    • Surprisingly, another Sonic example is Sonic the Hedgehog and Mortal Kombat, due to both franchises starting in the early 90s, both franchises being the go-to series for the Sega Genesis, and both being popular game series in the western world, despite the fact that Sonic is a family-friendly franchise and Mortal Kombat is an adult-targeted franchise.
  • The Book of Life:
    • The fandom boasts multiple crossover fanarts, especially with SpongeBob SquarePants.
    • This movie sparked a lot more interest in the Pixar movie Coco that is based on the Day of the Dead. The movie originally had a lot of flack from many wondering how you could even make a movie about the holiday, but The Book of Life proved you could make a good movie that wasn't just a Halloween redress.
    • Unsurprising, considering the mutual love for friendly, skeletal protagonists, but a lot of The Nightmare Before Christmas fans love the film. A common headcanon is that La Muerte is related to Jack Skellington, perhaps his mother or sister.
    • Kubo and the Two Strings also gets a lot of love from Book of Life fans due to the films' similar themes and fledgling cult status. The friendship between Gutierrez and Kubo creator Shannon Tindle helps as well.
  • A lot of Detective Conan fans enjoy Sherlock due to their main influence being the Sherlock Holmes canon. For some strange reason, they also enjoy Doctor Who.
  • The Dark Souls fandom generally gets along quite well with the Berserk fan base, due to the latter being s big inspiration for the former. Many fans bond over the similarities between the two franchises, enjoying the Expies, Shout Outs, and creating Berserk characters and builds in the games. This got even more pronounced with Bloodborne.
  • There's some overlap of mecha anime (especially Super Robot) fans and fans of tokusatsu series such as Kamen Rider or Super Sentai (and by extension, Power Rangers). It helps that Super Sentai outright has giant robots. For a while it wasn't too unusual to see tokusatsu threads on /m/. Generally, super robot fans will appreciate anything that has that "Super Robot Spirit" even if it doesn't have mecha.
  • Rhythm Game fans and Love Live! fans tend to have some sense of overlap. While part of this can be attributed to Love Live! School Idol Festival, there are rhythm game fans who watch Love Live! School Idol Project too.
    • Another Love Live! example, though only in the beginning phase so far, is CatDog and Love Live! on DeviantArt. There is some fanart of Honoka Kousaka meeting and even befriending Dog and a series of oneshot crossover fanfictions where Honoka lands in Nearburg is currently being written by a Deviantartist named SonicAndHildaFan11.
  • Steven Universe and Dragon Ball Z get along well since both series feature use of the Fusion Dance trope to combine characters into more powerful forms, and crossovers showing Arc Villain Peridot as Vegeta and Jasper as Nappa are very common.
    • In a more general sense, there are a lot of anime fans who are also fans of Steven Universe and vice versa. This has the side effect of having created a one-sided Fandom Rivalry, however, due to anime fans who aren't interested in Steven Universe getting inundated with Steven Universe discussion everywhere they go.
  • The Lion King, Balto, Wolf's Rain, Arashi no Yoru ni, Lady and the Tramp, Warrior Cats, and Spirit: Stallion of the Cimarron get along a lot due to being animal-centric works.
  • The Fox and the Hound, Leafie, a Hen into the Wild,Bambi, Ringing Bell, Watership Down, The Animals of Farthing Wood, and The Plague Dogs often share fans and fans tend to get along due to them being depressing animations about animals.
  • A lot of Undertale fans enjoy JoJo's Bizarre Adventure, likely due to similarities between DIO and both the Mad Dummy and Mettaton EX, as well as between Asriel and the Fallen Child and young Jonathan Joestar and Dio Brando, respectively.
  • At least on Tumblr, there is a good overlap between Les Misérables fans and Hamilton fans. Makes sense considering the similarities between Hamilton and the theatre adaptation of Les Misérables: both are musicals based on historical events, with some of their plot revolving around a(n attempted) revolution. It probably also helped that Hamilton debuted around the time Les Misérables fans were running out of material from the 2012 film adaptation.
    • For some reason, there was a period around 2016 when many Manga/Haikyuu fans were also Hamilton fans. Counterpart Comparison turned out to come surprisingly easily.
  • Labyrinth fans and Strange Magic fans tend to have a lot of overlap due to similarities between Jareth and the Bog King and the overall aesthetic of the film. Undertale pops up in the Labyrinth fandom as well, probably because both take place underground. With the popularity of Roommates and Girls Next Door, Pirates of the Caribbean, Phantom of the Opera and Les Misérables fans often have some presence in Labyrinth-dominated spaces, and vice versa.
  • The RWBY fandom has quite a few Studio Gainax or Studio Trigger fans in it, especially Kill la Kill and Tengen Toppa Gurren Lagann, mostly because of their Troperrific and Rule of Cool status. Justified as the creator of RWBY Monty Oum stated that at least two of Gainax's animes (the aforementioned Gurren Lagann and Neon Genesis Evangelion) influenced his show and confessed to enjoying the latter.
  • A peculiar case concerns GameStop customers, who tend to also be fans of the burger chain Smashburger due to their respective logos looking suspiciously similar.
  • TRON fans? Chances are, they're also working with ReBoot (very similar premise and computer humor). TRON: Uprising fans also gravitate towards Star Wars Rebels (similar themes and Doomed by Canon), or the Voltron reboot. And yes, they're also terribly friendly with The Big Lebowski, Babylon 5, and Scarecrow and Mrs. King
  • Fans of Warhammer 40,000 are, in many cases, also fans of JoJo's Bizarre Adventure. Probably because both franchises tend to be seen as both hyper-masculine and filled with balls-to-the-wall Crazy Awesome characters.
  • Yuri!!! on Ice and Check, Please! have a very close knit fandom. Both series focus on an ice sport (figure skating and hockey, respectively), and Queer Romance. Among other similarities, Yuri and Jack share an anxiety disorder while Bitty used to be an ice skater.
  • Many Yuri!!! on Ice fans are also Voltron: Legendary Defender fans. The massive popularity of male/male ship Klance probably has something to do with this.
  • For whatever the reason, the Warrior Cats fandom is really into Hamilton. The two fandoms share a lot of fans and there are numerous fan-animations to Hamilton songs.
  • Wonder Woman
    • Wonder Woman and Battlefield 1 fans really get along with each other as both of their works are set in World War I and are credited for reigniting popular interest in the conflict.note  There are many jokes and memes about how Wonder Woman would be great DLC material for Battlefield 1. Also both entries have their own version of a "killer" – Battlefield 1 has been called the COD Killer for having superior critical reception than its rival game Call Of Duty Infinite Warfare while the titular heroine of Wonder Woman is called a "God Killer" for killing the Ares the God of War.
    • In sharp contrast to the animosity between the DCEU and Arrowverse fans, there is a strong friendship between Wonder Woman and Super Girl fans. Diana and Kara are idealistic, cheerful superheroines who love ice cream and are praised as ideal female role models. It helps that there respective leads are good friends in real life.
    • While DCEU and MCU fans can't stand each other either online or in person, Wonder Woman and Agent Carter fans get along with each other. Both Diana and Peggy have been praised for being strong female superheroes in a World War setting who face sexism and discrimination for their gender. As an added bonus, Gal Gadot and Hayley Atwell are very supportive of one another and have made appearances together at fan conventions to promote female leads in geek culture.
  • Rogue One fans? Odds are that they also like Halo: Reach. Both are Darker and Edgier prequels of popular sci-fi franchises involving special forces squads for going on a Suicide Mission to recover data on a superweapon for the heroes of the original trilogy.
  • Supernatural and Good Omens, due to Good Omens sharing a lot of parallels with the later seasons of Supernatural (They feature the Apocalypse, not to mention both having Noble Demon characters named Crowley). Good Omens may get also thrown into the aforementioned SuperWholock fandom.
  • Many Flight Rising players are fans of Wings of Fire due to both being set in a world of sapient dragons in elemental regions.

    Anime & Manga 
  • While they are not too similar plotwise, many fans of Fullmetal Alchemist also enjoy Soul Eater. Perhaps because of their similar cast and production, or the similar messages and tones, the two are subject to much crossover. Also, they both ran in Monthly Shonen Gangan for nine years.
  • In general, fans of Dragon Ball are usually fans of One Piece, due to the similar art style and tone. It helps that Eiichiro Oda practically idolizes Akira Toriyama.
  • Basically any series by CLAMP has a significant fan overlap with any other series done by the same group. The fact that CLAMP wrote a Massive Multiplayer Crossover, Tsubasa -RESERVoir CHRoNiCLE-, that included characters from almost every series they've ever done essentially created a pan-series fandom.
  • Studio Gainax has a similar story, with fans that cross-over the studio's series more often than not. Popular cross-overs include FLCL-This Ugly Yet Beautiful World and Tengen Toppa Gurren Lagann-Panty & Stocking with Garterbeltnote .
  • Gainax fans and Studio Trigger fans are having close bonds. Just look at all those cross-overs between Kill la Kill and Gainax works, especially Panty & Stocking and Gurren Lagann!
  • The Puella Magi Madoka Magica and Type Moon fans are quite close to each other, and are frequently crossed over in fan art and the like. Probably due to author Gen Urobuchi being the writer of Fate/Zero. They even share memes between each other, with the Madoka fanbase using "Unlimited Gun Works" to describe Mami and Homura, and the Fate fanbase borrowing the "being meguca is suffering" meme for several Fate/Zero characters, particularly Lancer.
    • Also with other Studio Shaft productions. Especially Bakemonogatari (the glassy, modernistic backgrounds are somewhat similar, and Homura shares a voice and appearance with Hitagi (and, earlier, with Hanikawa)), Hidamari Sketch (artist Ume Aoki designed Madoka's characters, with Madoka herself bearing a strong resemblance to Hidamari's viewpoint character Yuno), and occasionally Sayonara, Zetsubou-Sensei for the show's emphasis on despair.
    • They also seem to get along with the When They Cry fanbase.
    • There's also a significant overlap with the Rebuild of Evangelion fandom in the form of fanart of Homura and Kaworu as friends, mostly due to both of them being interpreted as having same-sex crushes on their respective protagonists and going through multiple timelines in order to save them (a theory in Kaworu's case, confirmed in Homura's case). It's also something of a Running Gag for both fandoms to comfort each other over the Mind Screw and Tear Jerker natures of their respective series.
    • Shockingly, Madoka fans are rather amicable with the Tengen Toppa Gurren Lagann fandom. This is shocking due to the fact that both anime come from completely different genres, both at first seem to be on opposite ends of the Sliding Scale of Idealism vs. Cynicism and both have nearly different artstyles. However, aside from a few subtle similarities, the overlap comes mostly from the main characters Madoka and Simon who both started out as nearly identical characters before developing into similar but different characters at the end.
    • Princess Tutu and Puella Magi Madoka Magica tend to get along, as both are deconstructions of the Magical Girl genre that take a dark outlook.
  • The Attack on Titan fandom and Free! fandom are quite close, especially on Tumblr and Twitter, despite being from complete opposite genres. Interactions mainly consist jokes of characters crossing over, comparisons being made between them, or roleplaying.
  • While not as tight-knit, Big Windup, Yowamushi Pedal, Diamond no Ace and Kuroko no Basuke also tie in as sports anime Friendly Fandoms. People who watch one sports anime tend to get sucked into others, and as a result, there's a lot of fandom overlap.
  • Valvrave the Liberator Haruto/L-elf shippers, overcome with emotion from the Tear Jerker ending, jumped onto Hamatora, which began shortly after VVV ended. The "Nice Art" ship was observed to be similar to HaruEru, and thus, the Coffee Ship was born (named after Haruto's comment that he could be like sugar to L-elf's bitter coffee). Sorey/Mikleo of Tales of Zestiria, Inaho/Slaine (OrangeBat) of Aldnoah.Zero, and others have since been accepted into the coffee brotherhood.
  • Kuroh/Shiro of K, Shion/Nezumi of No. 6, and Allen/Kanda of D.Gray-Man are the "Black and White" ships, and are often compared and drawn in crossover fanart together like the Coffee Ships.
  • Quite a few Humongous Mecha fandoms have befriended one another thanks to the Super Robot Wars franchise. This is largely because SRW doesn't just Crossover the shows, but integrates their plotlines into a cohesive whole, which results in characters from different series befriending one another and often leads to better Character Development and happier endings.
  • Naruto and Queen's Blade is one hell of this, taking into account both series belongs to different demographics (Shōnen and Seinen respectively). The only thing they have in common is both series are action-oriented and the fact, at least regarding Naruto, is the fact some characters, like Ino Yamanaka, Tsunade, Hinata Hyuga and few other females definitely would not being too out of place in the Queen's Blade universe in any stretch.
  • Robotech fans are often very friendly with fans of the slightly earlier anime import Star Blazers. They tend to be of the same generation and most are fans of both. They are both sister icons of Old School anime largely associated with the "first wave" of Western anime fandom. Also, the opinion of purists notwithstanding, the two shows are the most successful early attempts by American anime importers that attempted to preserve the integrity of their respective original Japanese series (allowing more mature themes such as death, relationships, and character development).
  • Bokura no Hentai and Wandering Son fans tend to intersect and be friendly. This largely is because Marika is a Nitori expy in many ways, they both deal with transgender issues, and the former manga began just after Wandering Son ended.
  • There's a lot of mixing and friendliness between fans of Hunter × Hunter, Fullmetal Alchemist, and Naruto. When the Naruto manga ended many fans gravitated towards the Hunter X Hunter manga and 2011 adaptation, while a lot of Fullmetal Alchemist 2003 fans are fond of Hunter X Hunter 1999, with some also being fans of Hunter X Hunter 2011.
  • The "Big 3" - Naruto, One Piece, and Bleach - are friendly rivals. There's a lot of insult trading between them but many fans enjoy, or at least respect, the others as well.
  • Studio Ghibli fans tend to be "Studio Ghibli fans" rather than fans of individual movies. Fanartists and cosplayers enjoy crossing over as many Ghibli characters as possible. Also, hardcore Disney fans who tends to balk at the "weirdess" of anime in general tend to make an exception to Studio Ghibli due to their beautiful animation and general G-rating (don't tell them about Grave of the Fireflies)
  • Back in the day, there was a pretty well-known overlap between fandoms for One Piece and JoJo's Bizarre Adventure, primarily on the basis that they both have very distinct art styles, that Eiichiro Oda and Hirohiko Araki are extremely pop culture savvy in regards to both Japanese and western media and flaunt it in their work whenever they can, and that both series are Long-Runners whose stories have only gotten wilder and wilder since they began.
  • There is a ton of camaraderie between fans of Fist of the North Star, JoJo's Bizarre Adventure, and Berserk thanks to all three series' reputation for MANLINESS and the similar appearances of their protagonists and art styles. The three are sometimes called "The Holy Trinity of MANIME''.
  • Over the years, the Fandom Rivalry between fans of Pokémon and Digimon has mostly subsided, and the fandoms have become more and more friendly with each other. It's likely BECAUSE of the former rivalry that the two have grown close.
  • Lyrical Nanoha and Senki Zesshou Symphogear, since both shows feature Magical Girls with insane amounts of badassery and firepower... which begs the question: Which fandom beat the other up for them to become friends?
  • This was the case for fans of the works of Key/Visual Arts, but the popularity of both Angel Beats! and the TV adaptation of CLANNAD means that there are now a lot of people who like only one or both of those two and don't feel the need to get into any of the others. Angel Beats! especially, as it's very different from the romances. Still, a lot of the old guard are flat-out "Key fans" instead of just "Angel Beats fans," etc.

    Comic Books 
  • This often happens in Marvel and DC, when characters from various corners of their worlds are placed on the same team and these appearances are well-received and fans enjoy their faves' interactions.
  • Fans of various Marvel Comics books about teenage superheroes — Runaways, Avengers Academy, Young Avengers, New X-Men, Sentinel, Gravity, Avengers: The Initiative, Sam Alexander Nova, New Warriors, Journey into Mystery, Loki: Agent of Asgard, new Ms. Marvel and All-New Ghost Rider — tend to stick together. This also extends to various Spider-themed teens from alternate universes, like Spider-Girl, Ultimate Spider-Man or Spider-Gwen. And while not all of them like the main Spider-Man, he is getting a lot of respect for how influential his original stories were to the genre. They are also on good terms with their DC equivalent - fans of Teen Titans and Young Justice. And a significant part of Batman fandom, the one that enjoys adventures of various Robins, Batgirls and other teenage members of Bat-Family.
  • Spider-Man fans and 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 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 the Marvel horror line, that is books like Ghost Rider, Morbius, Werewolf by Night and Blade, are very friendly with each other and with Doctor Strange fans. In fact, a lot of fans of Marvel magic-themed characters seem to be getting along very well.
  • Franco-Belgian Comics, particularly Tintin and Astérix.
  • Fans of Swamp Thing and Animal Man tend to get along. Which is ironic, since their respective daddies - Alan Moore and Grant Morrison - really don't like each other.
  • Fans of Matt Fraction and Kelly Sue Deconick are extremely close with each other, which is rather fitting given that the two are married in Real Life.
  • Superman fans and Spider-Man fans tend 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.
  • Supergirl fans and Batgirl fans tend to get along marvelously, perhaps because of the similarities between both heroines (both are distaff counterparts of famous male heroes, both have been looked down on by comic fans because of it, both were fridged for decades, replaced and eventually brought back). Or perhaps because they are always friends in every comicverse and even other media as The DCAU, Super Best Friends Forever or DC Super Hero Girls. Regardless of the reason, Kara Zor-El fans use to be Barbara Gordon (or Stephanie Brown) fans too, and vice versa; and both fandoms respect each other.

    Films — Animation 

    Films — Live-Action 
  • Hulk and 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 Harry Potter films overlaps with that of Tim Burton's film of Sweeney Todd: The Demon Barber of Fleet Street due to the many shared actors in both films. Comments on YouTube clips of the latter often jokingly refer to Judge Turpin, Mrs. Lovett, and Beadle Bamford as Snape, Bellatrix, and Pettigrew, respectively.
  • Evil Dead, A Nightmare on Elm Street, and Friday the 13th. In addition to be three of the biggest horror franchises to come out of the 80s, 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 a cinematic crossover between Freddy and Jason, but also a comic book crossover between all three.
  • Giant monster fans of multiple franchises tend to get along very well, despite studio rivalries. Gamera fans and Godzilla fans are prime examples. Fan sites to one nearly always include the other and crossover fan-works are extremely common. In that vein, there are plenty of people who love Pacific Rim and Godzilla (2014) for being big budget giant monster movies. They turn rival when one camp dislikes the tone or execution of the other.
  • A surprising Odd Friendship has formed between Deadpool and Wonder Woman (2017) fandoms even though the heroes are complete polar opposites. It may be because Ryan Reynolds (a.k.a. "The Merc with the Mouth") himself offered his heartfelt congratulations to Wonder Woman when it outgrossed Deadpool. Alternatively, the cordialness between fans could be owed to Deadpool 2 making some sly shout-outs to Wonder Woman that Gal Gadot personally find endearing and funny.
  • Marvel Cinematic Universe
    • The MCU fandom gets along better with the fandom of Deadpool than with those of previous post-Avengers Marvel efforts by other studios mostly due to the fact that Deadpool's black comedy and graphic violence would be better off in its own universe than in the Lighter and Softer MCU, as well as the entire aspect of Ryan Reynolds Doing It for the Art and (very successfully) pushing his vision of a fan-friendly Deadpool onto the big screen. It helps that Deadpool avoids blatant jabs at 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 20th Century Fox, as the buyout addresses any potential Dueling Works animosity whether or not Deadpool and its sequel will be retconned or integrated into the MCU.
    • Surprisingly, MCU fans are on much better terms with MonsterVerse fans than DC Extended Universe fans. This may be due to both franchises sharing the same actors such as Aaron Taylor Johnson and Elizabeth Olsen for Godzilla (2014) and Tom Hiddleston, Brie Larson and Samuel L. Jackson for Kong: Skull Island. It could also be 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.

    Literature 
  • Terry Pratchett fans and Neil Gaiman fans, because of their collaboration on Good Omens.
    • And Douglas Adams fans overlap with both!
    • And Douglas Adams fans lap over with Doctor Who fans, since Adams was a writer and producer for the show, and one of his books, Dirk Gently's Holistic Detective Agency, was basically a rewrite of an unused DW script. Then Neil Gaiman 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 William Gibson 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.
  • The Chronicles of Narnia and The Lord of the Rings, 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 that his dislike for Narnia calling it an illogical pastiche of mythical elements.
  • Back when both series were originally coming out, the Sweep and Circle of Three 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.
  • Harry Potter and The Hunger Games fans are best buddies. They've oftentimes joined together against 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.
  • 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.
  • Nineteen Eighty-Four and Fahrenheit 451 readers, due to both novels revolving around dystopian 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.
  • Warrior Cats and Wings of Fire, due to the author Tui Sutherland being a member of Erin Hunter and creating Wings Of Fire.
  • Fifty Shades of Grey and older Twilight fans naturally get along, considering the former started life as the latter's fanfiction.
  • There's a ton of overlap between fans of The Raven Cycle and All For The Game, and even a fair amount of crossover fan work despite the relative differences of the two series.

    Live-Action TV 
  • Jeeves and Wooster and A Bit of Fry and Laurie, due to the shared double act of Stephen Fry and Hugh Laurie.
  • Joss Whedon's shows sometimes seem like they just have one big fandom. A good example of the "one big fandom" phenomenon is the Whedonverse Track at DragonCon, which is literally the fan track for ALL of Joss Whedon's stuff.
  • Joss Whedon's fandoms overlap with fans of Tim Minear, as he wrote and produced for several of Joss' shows, as well as creating shows with similar concepts which met the same fate as some of Joss'.
  • J. J. Abrams' shows.
  • Veronica Mars fans overlaps with Joss Whedon fans as well, likely because Joss himself was a fan of Veronica Mars (even making a cameo once) and because it features another snarky petite blonde title character who's a strong woman, similar to his Buffy the Vampire Slayer.
  • Tin Man and Alice - mostly because of their similar production staff and tone. Likewise with their literary ancestors. Baum was a fan of Alice in Wonderland.
  • Old-school Doctor Who and Blake's 7 were made by the same people and shared several actors, sets, and locations, so B7 became the original adult sister show to Doctor Who. Most B7 fans are also avid Doctor Who fans.
  • Blake's 7 has some overlap and friendliness with fans of Farscape and Firefly, as both can be seen as being "the 21st century Blake's 7", without being so similar as to arouse accusations of copying.
  • Sherlock and Doctor Who have a bit of overlap and crossovering going on (Sherlock overlapping more with Doctor Who than the other way round, due to a smaller fanbase) thanks to The Grand Moff being executive producer at both. Ever since Neil Gaiman wrote the very popular Doctor Who episode "The Doctor's Wife" for series 6, one which confirmed old fan theories, and contained a general display of awesome, and returned with "Nightmare in Silver" for series 7, the two fandoms have definitely gained a friendship.
  • The running gag Inspector Spacetime was well received by both Community fans and Doctor Who fans.
  • Smallville and Supernatural fandoms have a very, very large amount of overlap, to the point where it could quite reasonably argued that they share almost the same core base of fans. The fact that during the second half of the 2000s they almost always aired one after the other on the same network certainly helped this as did the fact that they were the two powerhouse Sci-Fi series that were basically keeping the ungrateful CW Network afloat. The then-current network president's perceived treatment of the two shows as Network RedHeaded Step Children (in favor of promoting shows like Gossip Girl or the 90210 remake as being the network's flagship programs) led to further unity between the two fandoms, which rightly or wrongly perceived themselves as being united against a common foe (namely, the perceived indifference on the part of the execs). The massive prevalence of fanfic crossovers between the two shows is also a testament to the unity between the Smallville and Supernatural fanbases.
  • Power Rangers and Super Sentai are two fandoms you'd expect to get into some variation on a Subbing vs. Dubbing brawl. And yet, that does not happen. Both the fans and production crews get along extremely well (to the point that they share sets and props, and for a couple of Super Sentai opening and ending sequences in the past few years, they filmed in New Zealand using the crew for Power Rangers), and forums for one will usually allow discussion of the other... The joint fandom can be expanded to include other Toku to various degrees; including Kamen Rider, Metal Heroes, and their various American adaptations (except maybe one we'd like to forget). The Japanese production house, Toei, has been encouraging this in recent years by including crossovers as part of their Milestone Celebrations.
  • Stephen Colbert and Jon Stewart seem to both share the same fandom. Makes perfect sense, since Stephen used to work on Jon's show, and they interact frequently. It's almost like The Daily Show and The Colbert Report are one show with two different hosts. Last Week Tonight with John Oliver and The Nightly Show starring Larry Wilmore are also included since they too star Daily Show alumni.
  • The Band of Brothers, The Pacific, and Generation Kill fandoms, whose fans are collectively known as the "HBO war fandom".
  • The King of Queens and Everybody Loves Raymond take place in similar settings and had frequent crossovers, and thus share largely the same fanbase.
  • Interestingly, Food Network shows generally have a lot of overlap in their fanbases, but not completely. While they are largely friendly towards one another, one celebrity chef's fans will often complain that several others on the same network are "too grating" or annoying.
  • There is generally a lot of overlap between fans of TNT's original shows.
  • Thanks to Tumblr, we get SuperWholock..
    • SuperWholock seems to have adopted Merlin into the fold and the entire friendship is most noticeable when something bad happens in one of the fandoms (whether it be the demise of a character or the end of the series) and the other fandoms take to comforting it.
      • This post, after the Who episode "The Angels Take Manhattan", pretty well sums up the relationship.
  • iCarly and Austin & Ally, despite being on rival networks (iCarly on Nickelodeon and Austin & Ally on Disney) have a friendship based around the supporters of the two major canon relationships on the show, Carly/Freddie and Austin/Ally, via both being examples of the Just Friends.
    • The same can be said with both iCarly and A.N.T. Farm, in a case similar to the above example, but replace Austin/Ally with Chyna/Fletcher.
  • Star Trek fans are known for their running feuds with fans of other Sci-fi series/franchises; notable rivals being Star Wars, Babylon 5, and Doctor Who. But it seems there's a lot of warm regard, if not necessarily love, for fans of the televised Stargate shows especially Stargate SG-1. As different as the shows are, their similar takes on military science fiction/Space Opera and comparable places on the Sliding Scale of Idealism vs. Cynicism naturally means they'd appeal to a similar group. Also, it's clear the producers of Gate pay homage, if ribbingly, to Trek. To top it off, throw in the number of Trek actors who've wound up on one or the other Gate series and it's almost impossible to see this fandoms as rivals. The affection later spread to The Orville, with not a small number of Trek fans thinking it makes a better Star Trek series than Star Trek: Discovery, and a large number of fans watching both.
  • For a long time on Sci-Fi Channel, Star Trek: The Next Generation and SG1 were both staple shows, sometimes airing within hours of each other.
  • Star Trek and 24 fandoms got pretty cozy what with all the former Trek actors appearing in the show in big and large parts. The connection was especially strong with Star Trek: Enterprise which saw Gregorty Itzin and Peter Weller doing both shows at the same time. (Itzin as President Logan on 24 while playing an alternate universe Starfleet Admiral on Enterprise. Peter Weller portrayed a Well-Intentioned Extremist on both shows!) The biggest connection was when Show Runner Manny Coto left Enterprise after it was cancelled and became a producer on 24. A Coto episode of 24 even saw a Bob Justman and a Rick Berman suggested to fill two open positions (Robert Justman and Rick Berman being longtime high-ranking members of the Trek staff.)
  • During The '70s, fans of Space: 1999 tended to also be fans of Star Trek reruns. Trekkies of that era sometimes credit the instant success of Space 1999 as one of the catalysts that convinced syndicated stations to also consider airing Trek reruns. In some areas, they were aired back to back.
  • Fans of one TV show made by Donald P. Bellisario (Magnum, P.I., Airwolf, Tales of the Gold Monkey, Quantum Leap, JAG, and NCIS) tend to be more than appreciative of his other shows. Not to mention the fact that much of the talent, both in front of and behind the camera is recurring.
  • There's quite a bit of overlap between fans of Downton Abbey and Call the Midwife. More specifically, fans who ship Mr Carson/Mrs Hughes on the former are very likely to also ship Dr Turner/Sister Bernadette on the latter. It's been speculated that this is due to the tremendous amount of physical and emotional restraint on the part of each pairing.
  • Fans of Deadwood tend to also be fans of Justified and visa versa. Both are unconventional Westerns and many regard the later show as a kind of modern day sequel to the former. It helps that they both star Timothy Olyphant and a bunch of Deadwood alums show up on Justified to the point where fans talk about which Deadwood actors they'd like to see next.
  • After a lot of ugly fan hate from Sherlock Fan Dumb, Elementary fans has found an Odd Friendship in Hannibal fandom. Part of it may have something to do with Hannibal fandom avoiding the big three SuperWhoLock like the plague. Although Supernatural and Hannibal alone get along well, due to sharing a few actors and juicy crossover potential.
  • The close relationship between Elementary fandom and Sleepy Hollow fandom, which enjoys quite a bit of overlap in fanbases due to both shows having racially diverse casts anchored by well-rounded women of color protagonists. Sleepy Hollow also has fan overlap with Scandal for similar reasons, despite being in totally different genres.
  • The West Wing and The X-Files fandoms often overlap, despite the shows' very different worldviews on the US government. The overlapping casts might have something to do with it.
  • Project Runway and RuPaul's Drag Race have a significant viewer overlap, and long time viewers of Project Runway will recognize Santino Rice on the judging panel for Drag Race. Both shows also have a significant LGBT Fanbase due to the sheer number of queer contestants on both shows.
  • The "Shondaverse" of shows including Grey's Anatomy, Private Practice, Scandal and How to Get Away with Murder overlap rather easily as creations of Shonda Rhimes, as the casts of the shows usually have a good presence on social media and encourage viewership of each other's shows; same with the fans. The actors move between the shows very easily, acting like an extended family and also pushing their cast mate's outside projects with ease. Several of them are also married in real life to other cast and crew members of Shonda shows.
  • 30 Rock and Parks and Recreation, definitely helped by the long lasting friendship between the respective leading ladies, Tina Fey and Amy Poehler.
  • The Game of Thrones fandom overlaps pretty significantly with the Harry Potter and Star Wars fandoms, partly because there are quite a few actors from both franchises in the cast of Game of Thrones. For Harry Potter fans, the show features David Bradley (Argus Filch) as Walder Frey, Natalia Tena (Nymphadora Tonks) as Osha, Michelle Fairley (Hermione Granger's mother) as Catelyn Stark, and Ralph Ineson (Amycus Carrow) as Dagmer Cleftjaw. For Star Wars fans, it features Gwendoline Christie (Captain Phasma) as Brienne of Tarth, Max von Sydow (Lor San Tekka) as the Three-Eyed Raven, Jessica Henwick (Jess Testor) as Nymeria Sand, and Julian Glover (General Veers) as Grand Maester Pycelle.note 
  • Agents of S.H.I.E.L.D. had a pretty big Fandom Rivalry with Arrow and The Flash (2014) back in the day as an extension of the Marvel/DC rivalry, but it strangely gets along well with the two's spinoff show, Legends of Tomorrow. It helps that both shows actually have a lot of similarities, being both ensemble shows about a varied cast who are overlooked by their larger Superhero setting, that started off on shaky ground but are generally seen as examples of It Gets Better. They also both feature a well-regarded female lead, Daisy Johnson and Sara Lance, respectfully, who's evolved into being the lead character after the show initially presented a White Male Lead in the form of Phil Coulson and Rip Hunter as their leads (though in both cases, Phil and Rip are well liked and their relationship with Daisy and Sara is well-liked). Yet, despite being very similar in format, the shows avoid feeling like they're competing since they have vastly different tones (Agents started off with a similar tone to Legends, but became Darker and Edgier as it went on, while Legends got Denser and Wackier as it evolved).
    • In a weird way, Arrow fandom has embraced the Marvel Netflix shows, particularly Daredevil (2015) and Punisher 2017. Not in the usual sense, mind, but a lot of fans of Arrow got tired of the Seasonal Rot the show went through and have since embraced the latter shows for also being dark and gritty dramas about vigilantes in a semi-realistic setting but without being seen as dipping in quality, to the point that, when Arrow was at its lowest points, their subreddit re-dedicated itself to the two.

    Music 
  • Most jazz and classical music fans and players will like each other and go to each other's concerts.
  • Metal bands which don't have a rivalry usually have some overlap.
    • This is subverted by Metallica and Megadeth who do 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 are how a lot of Metallica fans got into Megadeth.
  • Kagerou Project and Evillious Chronicles fandoms, to the point that most fans are fans of the other one involved. Mainly due to that both are epic Rock Opera franchises (Evillious more than Kagerou Project), and use Vocaloid to create Awesome Music. 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.
  • Yuki Kajiura and Yoko Kanno have both this and Fandom Rivalry, depending upon the specific persons talking.
  • Fans of the Foo Fighters and Queens of the Stone Age seem to get along well, since their front-men are involved in several projects together (Dave Grohl has even guested on a few QotSA albums) along with being poster-boys for modern alternative rockers' habit of having too many damn side-projects.
  • Fans of Queens of the Stone Age and Nine Inch Nails are also quite friendly; it helps that the two bands have toured together, and performed together at the 2014 Grammys (with Dave Grohl and Lindsey Buckingham, to boot).
  • Fans of Red Hot Chili Peppers like Foo Fighters because the bands are long time 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 Jane's Addiction too, especially as Flea was briefly in the band.
  • Nightwish and Sonata Arctica share a lot of fans, probably because the bands have toured together and the members are friends.
  • Mr B The Gentleman Rhymer and Professor Elemental have both this and Fandom Rivalry, depending upon the persons talking.
  • The fandoms of Tori Amos, Björk, and PJ Harvey have a lot of people in common. It's probably because they all started their solo careers during the early '90s and were in an interview together.
  • Otep, Amanda Palmer and Emilie Autumn. They're apparently all friends IRL. Also, to some extent, Courtney Love and Emilie Autumn (due to the fact that Emilie was in Courtney's backing band), but that sometimes turns into Fandom Rivalry instead.
  • Tupac Shakur fans and The Notorious B.I.G. fans used to not get along. Then, 1997 came around with both their deaths, and they are now far more amicable on account of Dead Artists Are Better taking effect.
  • Enter Shikari fans and Hadouken! fans. We don't know the exact reason, but it's nice to be friends, right?
  • Also The Qemists and Enter Shikari, 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, Goldfrapp and Ladytron have a severe fandom overlap.
    • Ladytron named themselves after a song by Roxy Music. Brian Eno, 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.
  • Melodic Death Metal 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.
  • Pink Floyd fans tend to like Kate Bush because Pink Floyd guitarist David Gilmour discovered her and has appeared on several of her albums.
  • Dan Bull fans tend to get along well with fans of In The Little Wood and to a lesser extent the Yogscast, due to Dan recording tracks with both of them and getting along especially well with the former. Similarly, his fandom have developed a growing relationship with Epic Rap Battles of History fans, in part due to Dan's terrifying depiction of Jack the Ripper.
  • Iced Earth and Blind Guardian 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.
  • Lana Del Rey fans are often also fans of Marina & the Diamonds. The artists themselves like each other's work, and their shared love of satirical lyrics wins over many fans.
  • The Within Temptation and Tarja Turunen 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 Homoerotic Subtext through the roof. The Sharja ship promptly took off, with 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 Neoclassical Punk Zydeco Rockabilly territory, and are subscribed to the same label - Warp Recordsnote . It also helps the fact that they both appeared in a handful of games such as Sleeping Dogs and Watch_Dogs 2note .

    Pro Wrestling 
  • Despite being separated by the ocean, CMLL and New Japan Pro-Wrestling are a quite famous example, to the point an annual multiple day event, Fantasticamania, was created to capitalize on it and several New Japan wrestlers have competed in CMLL's Universal Championship. That said, several New Japan wrestlers have also been members of invading La Ola Amarilla(an anti Mexican Evil Counterpart to La Ola Azul and La Ola Blanca) but that was initially just a collection of Japanese men lead by an All Japan wrestler on excursion(Shigeo Okumura) who wouldn't go back and just so happened to start recruiting many New Japan guys because they were the largest group of non Mexicans in CMLL and he could translate for them.
  • FMW and Big Japan Pro Wrestling generally have at least respect among each other's fan bases, which is an accomplishment for the latter as FMW Faithful tend to look down on other garbage feds besides perhaps W*ING and IWA Japan, which directly split off from it. It helps that Big Japan was one of the best substitutes for FMW during its inactive period, at least equal to the various, scattered would be successors that folded into the Apache Army. It not only had the expected bloodletting weapon/hazard matches, one of the few feds able to professionally live up to FMW in that regard, but also great wrestlers and martial artists, things many of the FMW followers tend to be lacking in.
  • Ring of Honor and Pro Wrestling NOAH, despite being based on two different continents. Even while NOAH had a deal with TNA, whose fans had long since stopped having such relations with the RoHbots, the ROH history of the relevant wrestlers was still used to promote them. However fandom doesn't always carry over to official response, as ROH's new Sinclair Broadcast Group owners in 2011 were convinced NOAH wrestlers like KENTA wouldn't draw. SBG eventually realized the error of their ways, too late for KENTA's return, but they sent popular wrestlers like War Machine and ACH to NOAH events with heavy promotion, perhaps as an apology and did bring in the much demanded Suzuki-gun.
  • Invoked in one of SBG's attempts to get ROH wrestlers to sign more exclusive contracts was to assure them they could keep their Pro Wrestling Guerilla dates and then told fans that PWG was an excellent promotion.

    Sports 
  • New York metro area baseball and football fans generally divide in the following way: fans of the New York Yankees baseball team generally are also fans of the New York Giants football team, and vice versa; meanwhile, the Mets baseball fans are generally also fans of the New York Jets football team. The intra-city fandom rivalry between the Yankees and Mets and the intra-stadium rivalry between the Giants and Jets helps add to this, as does the fact that before Giants Stadium was built, the Yankees gave the Giants a home at Yankee Stadium, while the Mets played host to the Jets.
    • It should also be noted that the Yankees/Giants fans and the Mets/Jets fans in New York City are generally united in their mutual love for the New York Knicks basketball team. However, the Yankees/Giants and Mets/Jets fans in NEW JERSEY often root for the Brooklyn Nets basketball team, which played for a long time in Jersey. Mets/Jets fans in Jersey who support the Nets, often proudly proclaim their love for "Mets, Jets, and Nets!"
    • Also, Yankees/Giants fans tend to root for the Rangers hockey team, and Mets/Jets fans support the Islanders (although fans from both fantoms who live in New Jersey will often root for the Devils).
  • Houston Texans and New Orleans Saints fans are generally amiable, even when facing each other.
  • In the UK and some commonwealth countries, there's a lot of overlap between people who follow Cricket during summer and people who follow Rugby Union during winter, perhaps because both are traditionally the sport for the rich (with the working class preferring Rugby League or Association Football, depending on region).
  • Fans of some Association Football clubs sometimes get along especially well with fans of certain other clubs, especially in Eastern Europe. Fans of CSKA Moscow and Spartak Moscow tend to respect Partizan and Red Star Belgrade, respectively, and the feeling is mutual. Fans of the Polish club Śląsk Wrocław are friendly with the Hungarian Ferencvaros, and CSKA fans also respect PAOK fans in Greece. This also extends to Western European fans, examples being Liverpool fans getting along with the fans of Borussia Dortmund, Chelsea fans having amiable relations with Rangers and Hellas Verona fans, Tottenham Hotspur fans being generally respectful of Ajax fans, or Celtic fans having good relations with fans of FC St. Pauli, PSV Eindhoven, Real Betis, and Napoli. Again, the feeling is generally mutual.
  • The increasing prevalence of women's Australian Rules Football aside, Netball is a kind of Distaff Counterpart to Aussie Rules, and many clubs have netball teams as well. In fact, a lot of local leagues have changed their names from "x Football League" to "x Football/Netball League" in recent years.
  • Fans of the Los Angeles Dodgers (based in L.A. proper) and the Los Angeles Angels (based in and formerly representing Anaheim) are completely comfortable in each other's presence, even in Dodgers vs. Angels games, due to their close geographical proximity leading to both teams' fans visiting the other team frequently.
  • During the 2017-18 NHL season, Pittsburgh Penguins fans were quick to forge camaraderie with the Vegas Golden Knights, a new expansion team. This is primarily due to the Golden Knights acquiring goalkeeper Marc Andre-Fleury, who was a fan favorite back when he played for the Pens. The Knights were quick to reciprocate after the Pens made a touching tribute to Fleury when he returned to Pittsburgh. During their surprise run for the Stanley Cup, the Knights also received a lot of support from Pens fans, primarily because they were facing Pittsburgh's rival, the Washington Capitals.

    Tabletop Games 
  • The World of Darkness is a More Popular Spinoff of Ars Magica, though the two gamelines are now thoroughly divorced from one another (and suggesting a crossover of the two is 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 Order of Hermes and the Tremere.
  • Veteran fans of of the now largely non-functional FASA Corporation's "Big Three" roleplaying games—Earthdawn, Shadowrun and Mechwarrior—often get on well with each other. It doesn't hurt that each game has its own setting to suit diverses tastes, or that they shared some writers for their expanded universe novels, either. This is particularly true for Shadowrun and Mechwarrior, since the two games have seen revivials on the PC.

    Theater 
  • In the Wicked section it's almost heresy not to have seen RENT or at least know the basic plot. It's probably something to do with the large number of shared actors especially Idina Menzel but there have been Wicked actors playing RENT, RENT actors playing Wicked, crazy crossovers, songfics with songs from the other musical and just odd references in fics.
  • Fans of The Phantom of the Opera and Les Misérables also tend to get along quite well (though many fans will, in the end, pick one show over the other as their "favorite"). It helps that both shows debuted around the same time in the UK and US, have similar music styles, and have become hallmarks of modern musical theatre. Plus, lots of performers over the years have starred in both shows. (The shows' respective 25th anniversary concerts shared quite a few performers, and Colm Wilkinson and John Owen-Jones — fan favorites in the lead roles of both shows — appeared in the encores of both events.)
  • At least on Tumblr, there's a good deal of fandom overlap for Matilda and Charlie and the Chocolate Factory, two West End musicals based on beloved Roald Dahl novels (the two shows also share a choreographer).

    Toys 

    Video Games 
  • BioWare fandom doesn't seem to care which game is better or not. If you find someone writing fanfic for Shepard, chances are they'll also have a Revan, and maybe a Bhaalspawn or Spirit Monk. As long as nobody criticizes Baldur's Gate, all is fine.
  • The few and proud fans of Sierra. King's Quest, Space Quest, Leisure Suit Larry, Quest for Glory... It's "Yes, please" not "which is your favorite?"
  • In the Console Wars, fans of First and Second Party franchises of the console they are representing tend to have a good relationship with each other and are even fans of each other's games. Such examples include Halo and Gears of War for the Xbox front, Super Mario Bros. and The Legend of Zelda in the Nintendo front, and Killzone and Uncharted in the Playstation front. One could think of these groups of fans as members of sports team. They might butt heads at times, but they more frequently backing each other up against the opposing 'teams'.
  • Know someone who plays Tetris: The Grand Master? Chances are they also play Bemani games and/or shmups. Conversely, Bemani fans and shmup fans view TGM as a new challenge that's worth giving a shot, instead of just crazy insane invisible antics.
  • DJMAX (or at least DJMax Technika) and Bemani. Many Technika players have a history of playing Bemani games.
  • Strangely, the Fighting Game fandom, in some regions, has started to blend in with, of all things, the Catherine fandom. At many fighting game events, you can expect to see the host running a tournament for Catherine's versus mode. Who knew that block climbing would become as popular as 20-hit combos? Also, here is the finals for an Ultimate Marvel vs. Capcom 3 tournament. You might notice that the game being played is not in fact UMVC3, but Bomberman. Yes, the grand finals for a UMvC3 tournament was decided over a round of Bomberman.
  • A lot of fans of Namco's franchises (Pac-Man, Tekken, Mr. Driller, Klonoa, etc.) are also fans of Capcom's franchises (Mega Man, Street Fighter, Ghosts 'n Goblins, etc.) Especially since there's Namco × Capcom, Street Fighter X Tekken, and Tekken X Street Fighter.
    • With Sega going third-party, these fans additionally appreciate Sega's games. Which is probably why Sega is included in the Namco × Capcom sequel Project X Zone.
    • Also worth noting that, unlike the notorious infighting in the Final Fantasy Series, most fans of Namco's Tales Series tend to be fans of multiple games - or, at the very least, they don't tend to actively hate on installments that aren't their favourites.
  • Historically fans of Sonic the Hedgehog and Super Mario Bros. have been bitter to each other. However, since the death of the Sega Dreamcast and the multiple games on Nintendo consoles, the two fandoms have gotten along pretty well for the most part. Until he was confirmed for Brawl, Sonic was the most demanded guest fighter for Super Smash Bros.
  • A great majority of Metal Gear fans are also Silent Hill fans as well. It also helps that the two franchises are from the same company, and that Hideo Kojima had a hand in making the Silent Hill reboot...until it got cancelled.
  • The Ghost Trick and Ace Attorney fandoms. Mainly because, were you to make a venn diagram of the two fandoms you'd have a smaller circle (Ghost Trick) inside of a larger circle (Ace Attorney). Furthermore, the Ace Attorney and Professor Layton fandoms are practically hand-in-hand already. Imagine the glee when a crossover was announced...
  • On a meta scale, this is a recurring aspect of the games made by Naughty Dog and Insomniac Games:
  • Several Space Channel 5 fans are, in turn, Jet Set Radio fans too. Also, Beat and Ulala is a somewhat popular Crossover Ship.
  • Probably due to a combination of both getting extremely rave reviews, having similar strategic gameplay, complete with perma-death, and similar emotional attachment to the characters, the fanbases of Fire Emblem Awakening and XCOM: Enemy Unknown are pretty good buds with each other.
  • Devil May Cry (the original series) and Bayonetta. Seeing as how both games have similar gameplay, and both their first games have the same director, this was obvious. There's even tons of crossover art of Dante and Bayonetta.
  • Bayonetta is paired up with Kratos a lot too. And some people have also noted similarities between her and Juliet Starling as well.
  • Undertale and OFF share many fans, due to similarities in graphics, monsters, and protagonists, as well as each having a shockingly dark storyline and showing you the consequences of killing everything in your path.
    • Similarly, fans of both of those works tend to get along with fans of LISA for the similarities to games like MOTHER.
    • Also, some Bullet Hell Shoot 'em Up gamers have a Noob Bridge with Undertale (at least in Japan) despite both being from entirely different genres, due to the similar gameplay mechanics.
  • The BioWare and Obsidian Entertainment fandoms have a tremendous amount of overlap and are very friendly toward one another. This starts with the creators themselves, with Obsidian often taking over projects that Bioware doesn't want to reprise. Both companies have their own flavors of high-quality, story-driven RPG, and fans tend to enjoy both.
  • The Monster Hunter and Dark Souls fandoms have a very low percentage of people who hate the other series; a lot of Dark Souls fans are also fans of the Monster Hunter games and vice versa, perhaps due to similar gameplay styles. Most forum threads comparing the two are met with comments about how they love and play games from both series. Besides, Dragon's Dogma is often seen as a hybrid between the two franchises and is well liked by the both fandoms.
  • Following Bethesda's acquisition of the Fallout franchise, a strong union has formed between fans of Fallout and Bethesda's other flagship property, The Elder Scrolls series. While the Fallout fandom has some very strong, differing opinions on the direction Bethesda has taken the series (starting with Fallout 3), Elder Scrolls fans have flocked to the Bethesda-produced Fallout games, and vice versa. One major reason is that Bethesda places a strong emphasis on World Building, which is one of the greatest strengths of each series. Another is the similar gameplay, with the Bethesda Fallout games adopting The Elder Scrolls trademark Wide Open Sandbox worlds and Western RPG elements. Heck, Fallout 3 and Fallout: New Vegas were made using the same engine Bethesda used for Oblivion, and Fallout 4 used a modified version of Skyrim's engine. This was made recursive when the Bethesda released the Skyrim Special Edition which was updated with the Fallout 4 engine and graphics enhancements.
    • Ever since id Software was acquired by Bethesda's parent company ZeniMax Media, these fandoms have even overlapped with those of id's franchises, including Doom, Quake, Wolfenstein, and Rage, all of which Bethesda has since had some sort of involvement in.
    • The same goes for Prey (2006), after Bethesda acquired it.
  • Donkey Kong Country fans tend to also be fans of other series Rare has worked on like Banjo-Kazooie and Conker's Bad Fur Day. Not only did the protagonists of the latter two series make their debut in a spin-off to the former, but much of Rare's humour and style tends to be kept similar among the different games they've worked on, and partly because they're implied to take place in the same continuity. See DK Vine and their DKU concept for more information on why this is (and why all these series tend to share the same fanbase).
  • The Disgaea and BlazBlue fandoms, despite both games being entirely different genres, seem to get along with each other. And both games have their good mix of quirky silliness and dramatic moments and both games are known to have a strong use of Moe.
  • Both Mighty No. 9 and Shantae: Half-Genie Hero launched their Kickstarter campaigns roughly around the same time, and the fandoms for both series not only get along swimmingly but also cross promote each other! Exemplified in this piece of art from one of artists at Way Forward.
  • With the Kickstarter for Yooka-Laylee, Mighty No. 9 fans have started to form a bond with Yooka-Laylee fans.
  • Joining the "Kickstarter original" group are the Shovel Knight fanbase and the Bloodstained: Ritual of the Night fanbase.
  • As of the eighth console generation, PC fans and Nintendo fans seem to be on much better terms with each other than with the Microsoft or Sony communities. This stems from a few sources - among other things Wii, 3DS, and Wii U games are usually completely exclusive, which erodes the usual PC "it'll get a port" attitude, and PC gamers tend to already possess a good-sized library of Nintendo games through emulators, which makes it hard to hate them. The eighth generation, though, seems to have solidified this attitude - particularly during E3, when many bemoaned the PS4 and Xbox One as being crappy PCs in disguise that touted useless gimmicks rather than actual games, many PC gamers strongly respected Nintendo for doing something new and different and focusing purely on the "gaming" aspect.
  • The Virtua Fighter and Dead or Alive fandoms are an interesting case; the creator of Virtua Fighter, Yu Suzuki, gave Tomonobu Itagaki pointers when he was creating the first Dead or Alive game. Itagaki is infamous for his attitude towards rival companies and games, especially Namco and Tekken, but Virtua Fighter is the one fighting game he has great respect for. The first DOA game was made for Sega's Model 2 arcade board, the first time Sega licensed the hardware, and the same board Virtua Fighter 2 was released on. Even after Itagaki left Tecmo, Sega helped Tecmo with Dead or Alive 5 and Virtua Fighters were featured as guest characters, so needless to say the developers of both series are on good terms. The two series even have similar button layouts. Between fans, it's more of a mixed bag. Some hardcore VF fans see DOA as being shallow, while some DOA fans think of VF as being boring. On the other hand, there is still a lot of overlap between the fandoms. VF players have gotten into DOA because of the guest characters in 5, whom have overall have been well received by the DOA fans, and many are hoping for a real crossover between the two series in the future.
  • Mario Kart and Super Smash Bros. fans get along well, with both being first-party multiplayer party games with popular online communities and Loads and Loads of Characters. It helps that Smash Bros. contains a subset of Mario Kart content, and the Mario Kart 8 DLC packs introduced content from outside of the Mario universe. They also share a common hatred of Moveset Clones, Tier-Induced Scrappy characters, and intrusive items.
  • Sonic the Hedgehog and Mega Man fans are very close with one another, with most people who like one having at least a passing interest in the other. At first this was just for cosmetic reasons (both have blue-colored protagonists, mad scientist main villains, mixing of sci-fi and fantasy, heavy presence of robots, etc.) but the two series became inseperable after the comics based on them got the same writer and an absolutely awesome crossover.
  • Mass Effect and Halo fans really get along with each other, possibly because their stories go in completely different but equally valid directions from similar bases. Crossovers between the series make up some of the most popular fanfictions on the net. Destiny seems to be joining this group, turning it into a Power Trio of sci-fi game fandoms.
  • Thanks to Operation Rainfall, Xenoblade fans, The Last Story fans, and Pandora's Tower fans get along really well and often overlap. Many of them are united with MOTHER and Fire Emblem fans thanks to a similar No Export for You troubles in the past, and the The Legend of Zelda fandom due to similar story and (especially in Pandora's Tower's case) gameplay elements.
  • Kantai Collection fans and Touhou fans tend to have a good amount of overlap, due to the fact that both series feature Loads and Loads of Characters and anthromorphic personifications of Japanese history (The Imperial Japanese Navy for the former, Japanese religion and mythology for the latter) and are ripe sources for memes. Even Touhou creator ZUN himself has good things to say about KanColle. This happens to a lesser extent though, with World of Warships. The latter had a reasonable influx of KanColle fans upon announcement of the Closed Beta sessions, since both games have featured vessels from the Imperial Japanese Navy. This does sometimes swing into Fandom Rivalry of sorts due to players not familiar with KanColle getting annoyed by the abundance of Yuudachi's "Poi~" in the in-game chat.
  • At first there was a Fandom Rivalry between the Team Fortress 2 fanbase and the emerging Splatoon fanbase, but both games ended up having enough in common for one fanbase to become interested in the other; with both games being team and objective-focused shooters with very cartoony aesthetics, incredibly silly antics, and most importantly, Hats.
  • Fans of classic 8-bit computer platforms such as the Commodore 64, Apple ][, Atari 8-Bit Computers and the ZX Spectrum, once bitter rivals in the Computer Wars in the '80s, have settled into this relationship after their platforms were discontinued. The proliferation of emulators on modern systems certainly helps, letting fans experience each other's platforms. PC fans also like classic consoles, including Nintendo and Atari. PC fans point to the ability to run emulators as one of the platform's strengths.
  • Fans of Metro 2033 are often fans of S.T.A.L.K.E.R., since both series feature Russian/Slavic themes and locations, and are both about a bitter struggle for survival against mutants, bandits, and the supernatural. On top of that, both were directly inspired by Roadside Picnic.
  • PC gamers tend to like classic arcade games (both physical machines and emulation/home ports) for the same reason they like Nintendo games: it offers an experience they can't get on PCs or consoles, especially with real arcade cabinets.
  • In the mid-2000s, due to several crossovers between the two series, fans of Capcom's Mega Man Battle Network and Konami's Boktai have become quite friendly with the other.
  • Nintendo fans tend to have a lot of overlap with the Bomberman fanbase due to Hudson Soft's extensive history with Nintendo, Bomberman's presence on every single Nintendo platform (except the Wii U), and his starring role in Nintendo's first crossover with another company. Around the releases of Super Smash Bros Melee and Super Smash Bros Brawl, he was one of the most requested 3rd Party Characters to appear in the series (right up there with the likes of Sonic the Hedgehog) and the leak of the official roster for Brawl was dismissed by several Smash communities due to his absence.
  • Because their Kickstarters both aired in the beginning of June 2015, there are many people who are fond of both Bloodstained: Ritual of the Night and Yooka-Laylee with many fans contributing to both of their campaigns and welcoming the return of some retro classics.
  • While in the modern era, Nintendo and Sony are locked in a battle to the death, Sony Playstation fans tend to also love the Super Nintendo, and see the Playstation, rather than the later Nintendo consoles, as the true Spiritual Successor to the Super Nintendo.
  • Sony Xperia users who played mobile games based on Nintendo franchises like Miitomo and Pokémon GO have better relationships with Nintendo and Sony, due to Sony Xperia devices running on [[Website/Google Android systems]] and Nintendo do have Android (and iOS) games based on their franchises. It's also worth saying that Nintendo and Sony don't have rivalries outside consoles.
  • Fans of Yooka-Laylee have come to be friendly towards fans of Super Mario Odyssey due to their gameplay centering around exploration of various sandbox worlds, as once envisioned in the fifth generation of gaming, a la Super Mario 64 and Banjo-Kazooie. Both games are slated for release on the Nintendo Switch.
  • It's not uncommon to come across people who play both Fate/Grand Order and Granblue Fantasy; both are mobile role-playing games with lots of attractive characters (including those that fall under Mr. Fanservice and Ms. Fanservice), each of which has their own distinct voice actor.
  • There's a decent amount of overlap between the Wario Land and Shantae fandoms, due to their status as collectathon orientated 2D platformers with detailed graphics that first originated on the Game Boy/Game Boy Colour.
  • There is overlap between the WarioWare and Rhythm Heaven fandoms. Probably because they're both microgame collection titles created by Nintendo and Intelligent Systems which (as of the last few games) share an art style due to a shared art director.
  • Street Fighter and Mortal Kombat fans have a lot of overlap, as both series were responsible for the Fighting Game boom of the mid-late 90s. Where there was something of a rivalry in their classic heyday, most fans generally played both due to them being the most popular 2D fighters of the era. Moreover, with the 2D Fighting Game revival in the Seventh Generation, both series saw an influx of newer fighting game fans who grew to appreciate both for their excellent new installments and their respective influence on the genre as a whole. Fans of both series are very eager to see the two crossover thanks to Capcom's history of crossover fighting games, despite the figurehead developers of either series insisting that it probably wouldn't work due to respective tonal differences and handling of violence.
  • After the Paladins "Cards Unbound" update caused massive Internet Backdraft, many players abandoned the game and were in need of a new free-to-play multiplayer action game. Many of these people chose Battlerite as their new game of choice, and were welcomed with open arms by the BR community. Even when "Cards Unbound" was later removed and many of the disgruntled players came back to Paladins, some still play Battlerite as well.
  • Spec Ops: The Line, Undertale, and Doki Doki Literature Club! share a lot of fans, as all three get very meta about the use of video games as a power fantasy and proceed to deconstruct that notion.
  • For obvious reasons, there's a great deal of overlap between fans of Grand Theft Auto, Scarface: The World Is Yours, and Mafia.

    Web Comics 
  • Dinosaur Comics and xkcd. Even their creators are friends! You can also count Andrew Hussie and David Malki! as creator friends with friendly fanbases.
  • The Dinosaur Comics and MS Paint Adventures fandoms get along rather well, considering that the official forums of the former are a section of the fora of the latter. This is probably because, again, the creators are very good friends, and because of a very similar style and humor.
  • 910Comics (The Wotch, The Wotch: Cheer!, Misfile, etc.) readers used to have insane amounts of overlap with El Goonish Shive Bunnies. Until El Goonish Shive joined the 910Comics community, and now they're the same fandom. Same with Zebra Girl, and probably others as well.
  • Cucumber Quest and Paranatural. The creators are friends, which contributes to fans of each comic finding out about the other. The comics themselves are both colorful, kid-friendly adventure stories that poke a lot of fun at themselves and their genres, but also have plenty of serious and heartfelt moments.
  • Stand Still, Stay Silent and Shotgun Shuffle are like this. The two webcomics were finalists in the 2014 Top Web Comic vote, and the final vote was extremely close. Several members of both fandoms popped over to the opposite side to see what the fuss was about, and a surprising number stayed.

    Web Original 
  • The two superhero parody shared universes of the early days of the Internet, Superguy and Legion of Net.Heroes. At least back when Superguy was active. They shared a couple of important writers in common, such as Mike Escutia and Dave Van Domelen.
  • In terms of the Yogscast, this happens quite a lot:
    • Even before Hat Films joined, their similar senses of humour, funny collaborations and similar presentation styles meant that both fandoms got on well. The fact that the two liked each other in real life also helps, and the news of them joining went down well for the most part.
    • Many early fans of Area 11 were also fans of the Yogscast, due to Sparkles* and Parv both being part-time members, the band generally getting on well with the group and the Yogs giving the band a rise in new fans and views. Similarly, their fans tend to get along well with fans of In The Little Wood and Strippin, since Martyn, Strippin and Sparkles* are Heterosexual Life-Partners.
    • Their relationship with Achievement Hunter (and Rooster Teeth) fans is mostly peaceful and respectful, with a significant degree of overlap although there are a few disputes.
    • Zigzagged with TotalBiscuit. The fandoms of the two initially were a straightforward case of this trope, but Lewis and Simon have since fallen out with TB. On the other hand, fans of TB seem to adore Sips and Hat Films to a lesser extent.
  • Rooster Teeth fans have a significant degree of overlap with fans of Freddie Wong (due to the two being good friends), SeaNanners (since Adam started as a Rooster Teeth fan before breaking out on his own), Arby 'n' the Chief (since creator Jon Graham and Rooster Teeth get on extremely well and have collaborated many times) and Halo (owing to their flagship series).
  • Kakos Industries attracted a large number of Welcome to Night Vale fans due to their similar formatting and mix of horror and Surreal Humor. Emerging Fanon theory is that Kakos is somehow linked to fellow Evil, Inc. company Strex Corp.
  • Fandoms for So Bad, It's Good fanime like Tsuki Desu, Nyan~ Neko Sugar Girls, and Tokyo Crystal Mew tend to get along due to their shared (often ironic) interest in hilariously poorly done series. It helps that many are intentionally bad.

    Western Animation 
  • My Little Pony: Friendship Is Magic:
  • Fans of The Amazing World of Gumball are open to pretty much 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, Miracle Star.
  • A rather odd example: the fandoms of Hey Arnold! would often get along with fans of Recess and have grown to have a mutual respect for each other, probably due to the similarities both shows have. This used to be the reason they originally have hated each other due to said similarities , but now that there is no threat of competition, fans of either are now often fans of both. note .
  • Many of the prominent Fanfic writers for Adventures of the Galaxy Rangers also wrote fanfic for Jonny Quest: The Real Adventures back in the 1990s. These days, newcomers to the fandom tend to be fans of X-Men: Evolution who discovered it via Red Witch and other fanfic writers. Later on, the Galaxy Rangers fan writers ended up writing 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 The Legend of Korra and Young Justice—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 Young Justice, The Legend of Korra and Green Lantern: The Animated Series also have alot 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 teams new show several times on Tumblr (and they return the favor.)
    • There's also quite a bit of overlap between the two Avatar series and Star Wars: The Clone Wars; 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 Avatar: The Last Airbender. Voice actor Dee Bradley Baker has also cited his roles in both shows to be his favorite voice acting roles.
  • Much like the Joss Whedon example mentioned above, fans of Greg Weisman shows seem to blend into one big fandom.
  • Young Justice and Green Lantern: The Animated Series fans have banded together. As the two headliners of Cartoon Network's weekend morning "DC Nation" block, they air in back-to-back time slots—and they were both subject to epic screwing by Cartoon Network when they were abruptly shelved about eight hours before airing their third episode after coming off summer hiatus. Needless to say, 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 Fandom Nickname "Symbiosi" (which, in Young Justice, is the Atlantean word for "together").
  • While they do have a minor Fandom Rivalry, most Adventure Time fans are also Regular Show, The Marvelous Misadventures of Flapjack, and/or Steven Universe 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 "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 a considerable overlap between fans of Green Lantern: The Animated Series and Teenage Mutant Ninja Turtles (2012), as several fans of the former began to watch the latter after the DC Nation hiatus happened. TMNT2012 also overlaps a lot with Super Robot Monkey Team Hyperforce Go!! 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.
  • Gargoyles and Star Trek 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.
  • American Dragon: Jake Long, Danny Phantom, and Randy Cunningham: 9th Grade Ninja, all being Kid Heroes who Wake Up, Go to School, Save the World 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 Tumblr and occasionally overlap with the smaller Detentionaire fanbase. Lastly, thanks tothe works of a writer known as QueenofHearts7378, it's starting to overlap with the Miraculous Ladybug fandom as well.
  • Danny Phantom, ParaNorman, and Dude, That's My Ghost!, because of the plot revolving around ghosts.
  • Many SpongeBob SquarePants 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 Phineas and Ferb, despite the two being completely different. This is because former writers had worked on or are still working 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).
  • Many Hey Arnold! 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 spiritual predecessors, American Dad! and Futurama fans are very friendly with each other due to the fact that both shows are considered better than their predecessors, they're not as popular or as successful as their predecessors, they have a similar style of humor and they both share some writers and producers.
  • In the 2000s, many SpongeBob SquarePants fans and Family Guy fans liked both shows and were very friendly with each other due to the facts that both were cancelled around the same time and revived in 2005, had similar jokes and characterization and both suffered through a heavy dose of Seasonal Rot around the same time for similar reasons. Not to mention that they both replaced established franchises as flagship shows (Rugrats and The Simpsons).
  • Fans of Looney Tunes and Tom and Jerry get along very well for the most part.
  • The Five-Man Band of 1980s cartoons is often said to be composed of He-Man and the Masters of the Universe (1983), Voltron, ThunderCats (1985), The Transformers and G.I. Joe: A Real American Hero. And, if you talk to your typical children of the Eighties, you'll see it's for good reason.
  • SpongeBob SquarePants and Regular Show as well, at least for the fact that the shows have similar characters.
  • Just like The Secret Trio and Rise of the Brave Tangled Dragons, fanbases of certain animated shows- with Kid Hero 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 Gravity Falls, ParaNorman, Coraline, Psychonauts, and to a lesser extent, Invader Zim and Danny Phantom.
  • Gravity Falls, Steven Universe, The Legend of Korra, and Over the Garden Wall, 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 Superwholock, the crossover between Steven Universe, Gravity Falls and Over the Garden Wall has been dubbed Steven Falls Over.
  • The fandoms of Teen Titans and Danny Phantom 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 Gravity Falls are enjoy other modern animated shows that resemble Gravity Falls and have staff who are friends of Alex Hirsch. Some shows include:
    • Star vs. the Forces of Evil. Star Butterfly has been positively compared to Mabel for sharing Mabel's Genki Girl personality, love of cute and colorful things like puppies and rainbows, and friendship with a savvy guy.
    • Ducktales 2017. Not only is Alex Hirsch's girlfriend the director of the show, but the new Webby has been favorably compared to Mabel for her Genki Girl personality and love of grappling hooks.
    • Rick and Morty. Not only is co-creator Justin Roiland a personal friends of Alex Hirsch, but Rick and Morty also has many references to Gravity Falls including a brief Crossover Punchline between the two shows. The fact that Stanford is confirmed to have traveled through several dimensions, a popular fanon has popped up that Rick and Stanford were friends if not more. The most common bit of fanon is that Rick Sanchez helped Stanford obtain the Infinity-Sided Die, and smuggle it through inter-dimensional customs.
