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.

- 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.
- Gene Roddenberry and George Lucas are documented as expressing admiration for the other's franchise. Lucas stated Trek influenced Wars, and Roddenberry acknowledged it was the massive success of Wars that led to the greenlight for Star Trek: The Motion Picture.
- Plus, the fact that a couple Star Trek alumni have voiced characters in Star Wars: The Clone Wars is further evidence that the days of the intense rivalry between franchises is pretty much past.
- Further, Reboot!Star Trek director J. J. Abrams has now been selected to direct the new Star Wars movies. (No word on a cameo from Chris Pine as a Jedi.....)
- 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.
- Mystery Science Theater 3000 fandoms. 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.
- 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 it to make consoles anymore they preferred making games for the gamecube because of the lots of similarities between the Nintendo and Sega fandom. It's not a wonder that those fanbases love to team up to rival against the Sony and Microsoft fandom.
- 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 Old Vic 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.
- 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 Miserables (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 doesn't help 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 Danganronpa 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 currently on hiatus leading up to the final act.
- Also for a short while with the Video Game/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.
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.
- 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.
- 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 genres (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.
- 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.
- The fandoms of The Secret of NIMH, An American Tail and The Great Mouse Detective all seem to get along with one another pretty well (as long as the topic of which film was better is avoided), with a lot of crossover fan art and fan fiction existing between them.
- Largely due to releasing around the same time and the respective protagonists' ages being close together, overlapping fandoms of the Rise of the Guardians, Brave, Tangled, and How to Train Your Dragon movies became Rise of the Brave Tangled Dragons.
- 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
- 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 a Doctor Who episode, 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).
- 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 9ľ" pages with an emblem of an owl carrying a broom inside the mockingjay ring.
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.
- 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 and is set to write another episode for series 7., one which confirmed old fan theories, and contained a general display of awesome- 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.
- 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 (and sometimes current) 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.)
- 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 Ru Pauls 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.
- 30 Rock and Parks and Recreation, definitely helped by the long lasting friendship between the respective leading ladies, Tina Fey and Amy Poehler
- Most jazz and classical music fans and players will like each other and go to each other's concerts.
- Kagerou Project and mothy's 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 songs) along with being poster-boys for modern alternative rockers' habit of having too many damn side-projects.
- 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.
- 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 New Jersey Nets basketball team. Mets/Jets fans in Jersey who support the Nets, often proudly proclaim their love for "Mets, Jets, and Nets!" It's unsure if the Nets' move to Brooklyn will change things.
- Also, Yankees/Giants fans tend to root for the Rangers hockey team, and Mets/Jets fans support the Islanders.
- Houston Texans and New Orleans Saints fans are generally amiable, even when facing each other.
- 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.)
- 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.
- 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.
- Touhou and Sound Voltex are slowly starting to become this, due to the fact that Sound Voltex has a large number of Touhou arranges. Only in Japan though, due to Sound Voltex being Japan-only; in the West, most Touhou fans are still unaware of non-Dance Dance Revolution 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.
- Alot 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 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.
- 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.
- 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.
- 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.
- Titanfall fans seem to be reasonably accepted by the Attack on Titan fans for a variety of reasons, not the least of which is the shared word in their respective titles. Once you realize that it's all about hyper-agile human infantry using mobility-enhancing movement rigs, fighting against towering humanoid foes called Titans that could kill them in a moment simply by crushing them, and that the only way to destroy a Titan robot is by a precision strike to the neck, and the Titans in Titanfall can be piloted much as Attack on Titan's Titans are suspected to be some kind of messed-up humans 'piloting' giant bodies, then you realize why "Attack on Titanfall" has become a thing lately.
- 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.
- Many of the prominent Fanfic writers for Adventures of the Galaxy Rangers also wrote fanfic for Jonny Quest: The Real Adventures back in the 1990's. These days, newcomers to the fandom tend to be fans of X-Men: Evolution who discovered it via Red Witch and other fanfic writers.
- Many Ed, Edd n Eddy fans moved on to My Little Pony: Friendship Is Magic, since both shows have a similar tone, and the latter show has some of the same cast and crew as the former.
- Gravity Falls fans are on very good grounds with My Little Pony: Friendship Is Magic, Adventure Time, Regular Show, Sponge Bob Square Pants, Invader Zim and EVEN modern South Park fans, mostly due to certain similarities between various characters and humor (With Invader Zim having less similarities to SpongeBob as the others)
- The fandoms of Recess and Hey Arnold! 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 butted heads, but now that there is no threat of competition, fans of either are now often fans of both.
- 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.
- Fans of Avatar: The Last Airbender and especially The Legend of Korra have a friendly rivalry with fans of My Little Pony: Friendship Is Magic. Things can get pretty heated over which of the two is better, but there's a lot of crossover between the two fandoms, and most of those who aren't fans of both are still pretty cool with the other show.
- 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").
- Adventure Time and Regular Show. Oh, so very much.
- 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.
- 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.
- Many Sponge Bob Square Pants 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 an interestingly similar case with Phineas and Ferb, despite it being completely different from Adventure Time. Again because former writers had worked on or are still working on the show. Heck, one of the creators (Dan Provenmire) was an occasional writer for Spongebob (and interestingly a director for Family Guy episodes from Season 2-Season 5).
- Many Hey Arnold! fans are usually friendly with Rugrats fans due to the fact that 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 Sponge Bob Square Pants fans and Family Guy fans liked both shows and were very friendly with each other due to the facts that both were initially given bad treatment by the networks, were both cancelled around the same time and revived in 2005, 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).
- While there is still something of a mild rivalry going on among some vocal minorities, for the most part fans of Adventure Time and Steven Universe get along. 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 air on Cartoon Network on Monday nights within the same hour. Can also overlap with Regular Show, also due to all three shows airing within the same hour.
- Fans of Looney Tunes, Tom and Jerry, and the Classic Disney Shorts get along very well for the most part.
