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:

    open/close all folders 

    Inter-Media/General 
  • In spite of the oft-hyped tensions between fans of Star Wars and those of Star Trek, truth is, outside of exceptions, 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.
  • 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.
  • Doctor Who and My Little Pony: Friendship Is Magic 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 it's 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, which is used to create most TF2 fanvids.
      • Similar to the Sonic/MLP example below, 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.
    • 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).
    • Homestuck sees a good deal of camaraderie with Bronies, partially due to both franchises tending to dominate attention across the internet and being resultant Base Breakers. Naturally, this also causes some strife. The fact that fan favorite badass Dirk Strider is a Brony serves to smooth out the edges.
    • 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 TF Wiki.
  • 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.
  • 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.
  • 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.
  • 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.
  • Pacific Rim:
  • Gravity Falls, ParaNorman, and Psychonauts have been developing into this.
  • 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 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.
    • Also for a short while with the Off fandom, though it faded into flavor of the month territory.
    • 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.
  • People who hold certain political/philosophical/religious views often conflate the views of opposing ideologies with other, separate opposing ideologies. However, this is almost always subverted in Real Life. Most of the time, if the more overzealous members of a group spread vitriol against one group they disagree with, they'll do the same for any other.
  • 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 Nineties, whose perception of Sonic was shaped tremendously by Sonic Sat AM (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.
  • The Book of Life:
    • The fandom boasts multiple crossover fanarts, especially with Spongebob.
    • This movie has sparked a lot more interest in the upcoming Pixar movie based on the Day of The Dead.
    • 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.
  • 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.
  • There's some overlap of mecha anime (especially Super Robot) fans and fans of tokusatsu series such as Kamen Rider or Super Sentai. 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.

    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 viwepoint 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.
  • 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.
  • The Haikyuu!! fanbase seem to get along with Free! fanbase and it's not uncommon for Free! fans to be also fans of Haikyuu and vice versa. It also doesn't help to note that both of the said shows had helped contribute the revival of sports anime in the North American fanbase in The New Tens. note 
  • While not as tight-knit Big Windup, Yowamushi Pedal, and Kuroko no Basuke also tie in as Friendly Fandoms.
  • 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 Cross Over 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, and the manga began just after Wandering Son ended.
  • Binan Koukou Chikyuu Bouei-bu LOVE! and Free! have a lot of mutual fans, due to them catering for the female audience through guy Fanservice. Due to the nature of the show, it's inevitable that magical girl fans also are part of the fandom.

    Comic Books 
  • Fans of various Marvel Comics books about teenage superheroes - mostly Runaways, Avengers Academy, Young Avengers and New X-Men, but also the ones with smaller fanbases like Sentinel, Gravity and Avengers: The Initiative - tend to stick together. Later on, fans of new Ms. Marvel and All-New Ghost Rider got added to the group.
    • 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.

    Film 

    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.
    • Back in perhaps 2005 or 6, 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, Tolkein, 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 Percy Jackson and the Olympians fans are best buddies. They've also allied with The Hunger Games fans (oftentimes against Twilight, although many Hunger Games fans also like Twilight due to Stephenie Meyer's exuberant praise for the book). 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 ring.
  • 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.

    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 Dragon Con, 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, similarly as 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 pretty much became the original adult sister show to Doctor Who. Most B7 fans are also avid Doctor Who fans.
    • Blake's 7 also 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 very 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 versus 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, similar to the above example, but replace Austin/Ally with Chyna/Fletcher. Similarity, both ships have the same 1st letter in their first names (Chyna to Carly and Fletcher to Freddie).
  • 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.
  • 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 Seventies, fans of Space1999 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.
    • A much better example is 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 pretty much 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, pretty much 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

    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 Crowning Music of Awesome. 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?
  • 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 Battle 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 Blindguardian) formed their side project Demons And Wizards and released two albums, which solidified the connection in the eyes of fans.

    Professional 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 The Beautiful Game, depending on region).

    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 
  • G.I. Joe and Transformers fans usually get on well and Shout Outs between the two are common. It helps that the two series are basically a Shared Universe.
    • My Little Pony fans also get along with with Transfans and Joefans, the three franchises being all owned by Hasbro. Although there was some friction caused by the more outspoken fans of all three groups, many regard the series as like siblings. When Howard Stern made a harsh criticism against the Pony fandom, the level of raging Big Brother Instinct coming out of the Transfans and Joefans was huge.
    • Likewise, many fans of Dan Vs. also get along well with the MLP fanbase. Both shows are on The Hub as it is.
  • My Little Pony fans are typically friendly with Breyer fandom; Breyer makes more realistic horse toys. Likewise many Pony fans get along with the Care Bears, Littlest Pet Shop, and Strawberry Shortcake fandoms.

    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...
  • Ditto with 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.
    • Within the Bemani franchise, it's hard to find someone who plays exclusively one Bemani series.
  • 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 X 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 X 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. It also helps that Hideo Kojima has a hand in making the next Silent Hill.
  • 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). It helps that Word of God verified that both games are in the same 'verse. 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 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.
  • 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.
  • Though some fans have differing opinions on Fallout 3, it's release by Bethesda has caused a union between many fans of The Elder Scrolls and Fallout franchises. The main reason is presumably that both franchises place a strong emphasis on World Building in their games.
  • Donkey Kong Country fans tend to also be fans of other series Rare has worked on like Banjo-Kazooie and Conkers Bad Fur Day, This is because 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 Nippon Ichi and Atlus fanbases.
    • Similarly the Disgaea and Blazblue fandoms, despite both games being entirely different genres, seem to get along with each other. It doesn't help to note the fact both games have their good mix of quirky silliness and dramatic moments and both games are known to have a strong use of Moe.
  • Howabout fandoms for two games that are still in the Kickstarter phase? Both Mighty No. 9 and Shantae 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.
  • 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.
  • Similar to the Star Wars and Star Trek example mentioned above, 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.
  • 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.

    Webcomics 

    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).
