In general, Original Media vs. Adapted Media. While particularly true with book-to-movie adaptations, any adaptation will have those who prefer it over the original and those who support the original, frequently coming down to which they were exposed to first or which medium they generally prefer.
In 2002, Attack of the Clones came in third in the annual box office, the first and only time a Star Wars film was not number one. Coupled with complaints about the prequel trilogy in general, fans of the franchise got hostile about the flaws of The Two Towers and Spider-Man.
Lampshaded by Clerks II. And of course they called the Tolkien fans gay, ignoring their own fandom's huge Obi-Wan/Anakin and Obi-Wan/Qui-Gon fandoms.
There is already some rivalry happening amongst fans of the 2009 Star Trek movie and the original TV shows. Once more sequels come around, expect it to get worse.
Now that J. J. Abrams has been given the reigns for both franchises, tensions have really heated up.
A really weird one to be sure, but there's a schism between Trek fans (more pronounced with older ones, but young ones are in the ranks as well) and Japanese Media, especially Anime. It's not unusual a Trek fan who likes Japanese media to be slammed for liking Tentacle Hentai and accusations run wild about moral issues.Pokémon and Dragon Ball Z get it the worst, accused of encouraging animal cruelty and violence. Most of the strife is internal, among fans of both media sources and opposers among the Trekkers, but it's still weird, considering Trek has a modest Japanese fandom and even a decently popular Manga.
Fans of the 90's cartoon show tend to accuse people who came into the fandom because of the Nolan films of being Bandwagon fans. Not that Nolan fans are completely innocent - they can be pretty snobby about how "unrealistic" all the other incarnations are.
One could say it all comes down to which Joker you prefer. Few people seem to realize that this is The Joker we're talking about, and he could very well be both.
Another level of silly is added in that both Anime and Western studios are known for outsourcing their animation to South Korea± In the 1980's and early 1990's, American studios often outsourced to Japan itself; this changed when Japan became too expensive, meaning that some examples of either one were animated by studios that produce the other. Also, all animation is called "anime" in Japan.note Ironically, a few in Japan have taken to distinguishing their own cartoons with the long since fallen out of favour term "Japanimation".
American-style comic books vs. Manga, though, like the anime vs. Western animation example above, there are lots of people who like both. Manga has also influenced Western comics that way anime has influenced Western animation.
For a brief time, fans of the Pokémon anime vs. Rugrats fans. When the popular Pokémon anime lost the 1999 Kid's Choice Award for Favorite Cartoon to perennial winners Rugrats, Pokéfans accused Nickelodeon of rigging the votes so their money-maker at the time would always win.
Ditto Sonic SatAM fans, if not even more so since SatAM was cut short after the second season's twist ending because it lost the timeslot conflict to Power Rangers, which FOX intentionally instigated. The young fans did not understand what happened then, but when they learned the reason later in life it turned them bitter.
Gargoyles vs. Power Rangers in most markets, Gargoyles was up against Power Rangers in the ratings wars. Power Rangers won, and so Gargoyles fans believe their intelligent, character-driven, highly literate, William Shakespeare-celebrating show was defeated by the bad acting, cheap props, and poor writing designed to appeal to the Lowest Common Denominator.
This was exacerbated when it turned out the Airbender sequel series The Legend of Korra would also use "The Last Airbender" as a supertitle though it's a case of Artifact Title. After complaints, it was dropped.
There's one between fans of the Resident Evil games vs. fans of the films. At first there was cross pollination, but after awhile they became separate fan bases.
And now there's Star Wars: The Clone Wars vs. ...basically the entire rest of the Expanded Universenote This stems from the fact that The Clone Wars is a higher "level" of continuity than most other EU sources, thus, if there's a contradiction, the other source is rendered invalid. The problem results from the other sources being as many as two decades older than the show, with the sizable and loud fanbases you'd expect from something that old..
Though it would fit more in a toy section, the BIONICLE vs. Hero Factory debate is something that has rocked fan sites of either line, especially places like BZ Power. Despite the war being only 1-2 years old, it already has its own 'political' spectrum. You either think Hero Factory is the best thing since sliced bread and hate Bionicle with the intensity of a thousand burning suns, prefer the line over Bionicle, don't care either way, dislike certain qualities about Hero Factory and prefer Bionicle, or hate Hero Factory with the passion of a burning suns and think Bionicle is the best thing since sliced bread. Of course, there is probably another part of the spectrum we overlooked. The debate has even caused people to question administrative bias in certain forums!
The Stargate fandom seems on the verge of declaring war on all of Professional Wrestling, largely because the Sci Fi Channel's contract with WWE essentially forced Stargate Universe to move from Fridays, which held the Stargate Verse shows for over a decade, to Tuesdays, where it had much worse viewership, leading to its cancellation.
There is also a rivalry between fans of Stargate SG-1, and those who prefer the slightly differing continuity of the film.
The Fandom Rivaly on /co/ between the two seems to be dying down however as the rest of /co/ utterly despises them and forces them to post in "general threads" so they don't clog up the whole board. Many fans tend to stay out of the generals though, as they're usually filled withRule34.
In LJRP, they at least have one thing in common: both receive(d) massiveHype Backlash.
Someone clearly forgot Battletech fans versus Mechwarrior fans. This epic debate practically typifies the huge legal (and fandom) schisms that happened in the late Nineties. As multiple companies who owned parts of a single universe decided they wanted the whole cash cow for themselves, they took their parts and retreated into their holes, trying to wait the others out. As this happened with many universes, the Battletech companies decided to all try this at once, leading to a cold war which rages today, and further ties in with Macross calling BattleTech a legal ripoff, and has locked the universe in perpetual progression hiatus. Either way, the BattleTech Fans say the Mechwarrior series is a claptrap videogame translation of a complex and dynamic Tabletop Game, while Mechwarrior Fans insist that BattleTech is a crappy and dated anime ripoff. Neither side will pause for one second to consider that Mechwarrior is the name of the Battletech videogame line. This strange Broken Base stems from the decay of the now derelict universe (and fanbase) over the course of a decade. This has actually garnered legal attention, as the huge paper war (over who has which rights on what aspects of both games' universe) has led the fandoms supporting the different companies, and even specific bundles of copyright-held fluff regardless of ownership!
This only gets worse when you realize that if either half of the Broken Base wants their franchise to progress, they will need to work together to provide a demand for the game, which will then force one side of the legal battle to give up their death-grip in exchange for royalties on their rights.
Oh the Nineties, they were a simpler, more naive time.
Fans of Bakugan vs. fans of Transformers Animated. TFA fans despise Bakugan for its negative effects on the initial run of Transformers Animated; Bakugan fans strike back by claiming TFA's inferiority. The arguments about the rival toylines are far more heated than those of the animated series.
Fans of The Lion King versus fans of Kimba the White Lion due to claims that The Lion King ripped off Kimba. Now, long after the plagiarism accusations surfaced, it's unlikely anyone at Disney would admit that Kimba inspired TLK because of the sheer vitriol spewed at them for continually denying even the suggestions that it was merely inspired by Kimba and not a rip-off. Also, it's probably very likely that fans of The Lion King would also be fans of Kimba if Kimba's Fan Dumb hadn't given their own show such a bad name - both are good stories, although, The Lion King took some key liberties - for one thing - the presence of humans, the show often deals with greedy or well-meaning but otherwise ignorant humans encroaching on Kimba's kingdom - The Lion King has no humans at all.
Touhou fans tend to be offended at being compared with "Bronies" usually.
Sonic the Hedgehog fans and My Little Pony: Friendship Is Magic fans are notorious for clashing very frequently on each other's fansites. At one point, there was so much hate on both sides that Equestria Daily eventually temporarily immediately disqualified any Sonic crossover art from being featured within it's "Drawfriend" entries due towards the complaints they got from it. It's been commonly theorized that the reputations of both fandoms have much overlap, and both fandoms clash in an effort to distance themselves from each other.
Though there is an isolated contingent of fans who get along just fine(often playing up the similarities between both series' characters in fan art ie Sonic and Rainbow Dash, Knuckles and Applejack, among others), a majority of the Sonic fanbase do not get along well with and take offense to being compared to bronies. Likewise, the more vocal bronies do not get along with the Sonic fanbase at all either.
Disney fans and Marvel Comics fans found themselves in confrontation after Disney bought Marvel in 2009. Marvel fans complained that Disney was going to ruin Marvel through Disneyfication, and Disney fans made the general complaint that by purchasing Marvel, Disney was continuing to move away from its core businesses and turning into just another Mega Corp. The complaining died down considerably on both sides after the release of Disney's first in-house Marvel movie The Avengers in 2012, though it picked up again somewhat on the Disney side later that year when Disney purchased Lucasfilm.
There was a fairly violent Fandom War between Homestuck and Axis Powers Hetalia for a while. It's cooled down ever since members of both fandoms began complaining about the pointlessness of the whole thing (...and now the two fandoms are basically BFFS.)
The Homestuck and Danganronpa fanbases hold some animosity towards one another, partly because Dangan Ronpa fandom started picking up steam around the same time Homestuck went on a lengthy hiatus. This resulted in Homestuck being given the credit for Dangan Ronpa's popularity and Dangan Ronpa fandom being treated as an outcrop of/temporary refuge for bored Homestuck fans, which annoyed DR fans who like the franchise in its own right. (Homestuck fandom has a similar relationship with OFF fandom, but there's less resentment there.)
In Japan, there is a fairly persistent rivalry between fans of Kamen Rider Ryuki and Fate/stay night. Both shows being quite mature despite working within a medium typically aimed for children, while sharing the similarities of having a plot based on a battle royale between a number of combatants, there have been accusations by both sides of one show ripping off the other.
Of course then you have Gen Urobuchi, a good friend of Kinoko Nasu as well as the co-author of Fate/Zero, who's a self-professed fan of Ryuki.
Although, Flocks have their popularity be selling merchandises and Bronies have their popularity online, but both fandom wants the other popularity as well (Bronies wants more merchandises and Flocks wants more online time).
Book Wicked vs. Musical Wicked, and both versions against Oz: The Great and Powerful. Which is the best story? Which works best as a prequel to the 1939 film? Which is the best portrayal of the Witch of the West? Despite all being Oz prequels (and one being an adaptation, no less) they're all wildly different stories that tend to attract different kinds of fans, who all want their choice to be the "best" or "true" Oz prequel. The constant rumors of a Wicked film adaptation and arguments over whether it should be based on the novel or the musical don't help matters. If it's ever made, it'll probably end up here too.
Now that the DC Cinematic Universe seems set to kick off properly, the glorious war between it and the MCU can truly begin. Not helped by the fact that the studios seem to be throwing fuel on the fire - Batman v Superman and Captain America 3 both have the same tentative release date: May 6, 2016. Most watchers agree that one of the films will probably change its date before then, but for now fans are just waiting for one of them to blink.
And DC blinked first; they've moved Batman v Superman to March 25th.
This also extends to their Live-Action TV fronts. Marvel's Agents of S.H.I.E.L.D. has been getting hate non-stop from fans of DC's Arrow, largely as an extension of the Marvel/DC rivalry. Generally, one will argue that the other had weak opening episodes, poor dialogue, poor acting/characters, and its handling of a specific group is very poor and leads to Unfortunate Implicationsnote Notably, Arrow has been criticized for its handling of female characters, which AOS has been praised for handling well, while AOS has been criticized for its handling of African-Americans, while Arrow has been praised for its handling of such; both, though, have came under flack for killing off their only LGBT characters , while the other will make these same criticisms about them.
Due to Attack on Titan (Shingeki no Kyojin) and Shin Nihon Kikaku sharing the same initials, the AoT and SNK (Playmore) fandoms seem to have acquired a bit of a rivalry on Tumblr due to the "snk" tag becoming comprised of almost nothing but AoT posts.
Pinball fans became angry against video games and how they took over arcades in the mid-'80s, mostly displacing the pinball tables they loved. Meanwhile, the new audiences brought in by these arcade video games had little interest in pinball and viewed pinball fans as whiny geeks stuck in the past. As the years went by, the rivalry became bitter as pinball companies continued to struggle through The Nineties while video game companies thrived, as video game companies successfully transitioned to home consoles leaving pinball companies stuck with the dwindling arcade scene in North America, and as every major manufacturer of pinball tables closed shop by 1999 except Stern Pinball. Fans of video games and fans of pinball are still practically on non-speaking terms.
Stuart Ashen and Weebl (creator of Weebl & Bob) have announced a 24-hour charity stream for StickAid which coincided with the Day of the Doctor. However there are no news of Whovians going ballistic on this one- the fact that it's an event for charity and that they didn't try to claim that it was their day helped.
The event also happened on the same day as the season 4 premiere of My Little Pony: Friendship Is Magic. Despite the anticipation of some whovians, no wars between bronies and whovians broke out. The fact that there's a fandom overlap and that the bronies did not try to claim this as their day, and that both shows aired at completely different times that did not overlap, helped. This is good as both shows have a very large and vocal fanbase, and the Internet would suffer if a war did break out.
Things may have died down a bit when on 1DDay, Matt Smith and other Doctor Who cast members appeared via video link to talk to the One Direction boys. The boys have also gone on record saying they're massive Doctor Who fans.
It started when both fandoms claimed that one was a rip-off of the other, as they were out at around the same time. The fighting got to the point that a lot of people decided that anyone who was a fan of both wasn't really a fan on their side. Adding to it, Digimon was an evolution of Virtual Pets; something Pokemon never stepped into until recently, save for the heavily forgotten Pokemon Pikachu pedometer, and even then the Pokewalker was just adding onto it. Digimon added fighting to it for an advanced "pet" feel, with more and more tougher forms as they evolved. Pokemon was more or less an evolution alone of any RPG; they only added Evolution in exchange of special skills, weapons, and so on.
Then Chaotic came along and soon this conflict is worthy of an FPS and RTS.
Digimon stepped down after Yu-Gi-Oh! came in, seeing as some kids stopped watching it after 02 ended. Also, for a while, there was Yu-Gi-Oh! vs. Duel Masters.
Beckett Magazine played up these rivalries in their covers.
In some places it was Pokémon vs. Digimon vs. Dragon Ball.
More recently, Pokémon vs. Bakugan. The tension between fans of both series, young and old, is so thick you can cut it with a knife.
Digimon also has a rather brutal civil war going on. Pick a season, any season, and no matter how you felt about it someone out there will tell you how wrong you are. And Goddramon help you if you so much as mentionFrontier.
Within Pokémon itself, fans of 5th generation starters Snivy and Oshawott seem to have a rather heated rivalry. The fans of Tepig, such as they are, seem to be staying the heck out of it. Not to mention the old school fans' rivalry with anyone who likes games from later generations, with "later" being defined as anything after Gen. II or even Gen. I in some cases.
Rivalries between fans who prefer the games and fans who prefer the anime and/or manga can get rather heated as well.
Sometimes it has been the whole rest of the Anime fandom against Pokemon due to feelings that Americans got a wrong impression of anime from it (especially with the 4Kids dub) or that they didn't realize there was other, and better in their view, anime out there.
Also within Fullmetal Alchemist fandom between fans of the manga and its direct anime adaptation Fullmetal Alchemist: Brotherhood, and the loose 2003 adaptation. It's mostly died off now that the manga is over, though you can still find fights about it sometimes on Tumblr and other places where flamewar-loving fanboys and fangirls gather.
There are many conflicts between the fanbases of the various Gundam shows, but the classic one is UC vs Gundam Wing.
A more recent one is Gundam SEED Destiny vs. every other Gundam series. (The unfortunate thing about this is that Gundam SEED - a good series in its own right - gets dragged into the hatedom.)
Recently over on /m/, with the VOTOMS's apparance in Super Robot Wars Z2, alongside Gundam 00 and other Gundam titles, there has been some....rather heated debate. it led to everyone who likes VOTOMS being called "hipsters" who hate anything that is popular, while this in itself led to a lot of trolling, it came full circle when someone pointed out that Gundam fans on the same imageboard are pots calling the kettle black, and routinely complain about Gundam SEED and Gundam 00 for, you guessed it, being popular and not being like UC Gundam (see above). and it led to THEM being called "hipsters". and now it's sort of a meme now to call everything that gets discussed there "is for hipsters"
Gundam vs Neon Genesis Evangelion - in The NinetiesEVA in manga format and Gundam Wing were the only two positions from Humongous Mecha genre on the market, leading some people to believe that EVA is deep and intelligent while Gundam, all of it, is stupid. While mostly discredited, this stereotype prevails to this day, much to annoyance of Gundam fans. On the other hand, the opposing stereotype is that Gundam is Closer to Earth, whereas EVA is snooty and pretentious. This view, unlike the other, holds much more of a sway over today's anime fandom.
For over the past decade, the most popular shonen battle anime/manga (at present writing) are One Piece, Naruto and Bleach, generally referred as the Big 3. Since they're all the same genre, they have a similar core story structure, so it's entirely possible to enjoy more than one at the same time. However, it's also because of those similarities that fans of all three are at a Męlée ŕ Trois, but it's surprisingly evened out: for every one fan who likes one and dislikes two, others like two and dislike one, while just as many like all of them equally.
More recently, Toriko has quickly established itself as a powerhouse in Japan. Some are already saying that it's replacing Bleach as a flagship manga for Shonen Jump (in light of Bleach's anime ending), and the author of One Piece himself has declared Toriko as his biggest rival. However, until the anime arrives overseas, we're uncertain of whether or not the western fandom will enjoy Toriko quite as much to include it in the discussion.
Occasionally, Fullmetal Alchemist would have been added to the mix, with the debate centering on whether it's too different to compare to the other three, and if not, whether it's the best out of the four. Notably, that discussion is far less heated (especially once FMA ended), if only due to FMA fans having their own Fandom Rivalry within their own base (e.g. the first anime vs the manga and the second anime, as mentioned earlier).
In spite of both having their anime version end prematurely, Fairy Tail and Blue Exorcist are creeping their way into the debate, though neither are in the same level as Toriko right now. The argument over Fairy Tail is whether it has the deepest character relationships, or if it's too much of a Fanservice-laden series. The argument over Blue Exorcist is between those who feel it plays around with a lot of supernatural show tropes, and those who think it's a generic shonen with prettier characters.
Meanwhile, fans of Fairy Tail and fans of One Piece are often at each others' throats due to the similar art styles and how Fairy Tail's author Hiro Mashima vehemently denies being influenced by anything related to One Piece.
This is made more amusing with the English voice cast, where they both feature Yuri Lowenthal as a passionate idealist and Johnny Yong Bosch as a calculating, sometimes Necessarily Evil pragmatist, as main cast members whose ideals clash with each other. The difference is that Yuri is the star of Gurren Lagann and Johnny is the star of Code Geass, with the other's ideals being portrayed as misguided.
If this thread is any indication. To put it simply, the former group was blaming the latter for their lack of a second season of their show. But with Endless Eight rearing its ugly face, guess which side had the final laugh on virtue of not raging hard at itself.
Mind you, if Haruhi EVER enters a power level battle discussion, it'll be outright chaos as people argue who is stronger out of Haruhi and your favourite mecha that jumped out of Pandora's box.
To muddle things even more, many Haruhi fans jump to the movie as an argument. Given the praise of the movie, many turn around and then argue that K-On! is to blame for ruining the 2nd Season and that it would have been amazing had time not needed to be split.
Neon Genesis Evangelion vs. RahXephon, fans of the former accuse the latter of copying many elements from their series (as well as End of Evangelion to a lesser extent) while fans of the latter counter by saying theirs is superior critically.
It did not help either side that the plots for both anime franchises were very tightly merged together in Super Robot Wars MX.
Speaking of Madoka, looks like Nanoha fans are gearing up for a show down about being dethroned as the most popular non-standard magical girl series.
Madoka fans also do heated battle with fans of classic magical girl shows like Sailor Moon, Cardcaptor Sakura and Pretty Cure. As well as with the fanbase of Revolutionary Girl Utena over which is the better Deconstruction of the genre, if Madoka is considered a deconstruction at all. The more recent Happiness Charge Pretty Cure has gotten a lot of ire from the Madoka fandom as they perceive the series to be a Take That towards them as the characters can achieve their dreams without being punished for it, act selflessly for others without expecting to benefit from it, etc.
Princess Tutu is another Magical Girl deconstruction who's fans occasionally butt heads with Madoka's fans, to the point that it's been said that if one were to have watched Tutu first, they would have hated Madoka.
Fans of the character Madoka have rivaled Haruhi fans over which one is the "real" God figure.
Madoka is often compared to Neon Genesis Evangelion. However, on /a/, it's probably best to keep Madoka fans and Evangelion fans at least five miles apart, especially with the movies for both franchises playing in late 2012. Needless to say, both argue over which is the better Darker and EdgierDeconstructor Fleet series.
Fans of Pokémon vs. fans of Inazuma Eleven. Inazuma Eleven fans label Pokémon as having no progress despite its Long Runner status, Pokémon fans label Inazuma Eleven a shallow and contrived series that is hated for stealing ratings in Japan.
It's even more intense when fans outside Japan were factored. Inazuma Eleven is much more popular in Britain due to the footing soccer has there, while Pokémon is one of the Gateway Series to American anime fans, and the US as a whole couldn't care less about soccer.
Though it doesn't seem that bad in Japan itself, as there's quite a bit of crossover fanart in Pixiv, and it even has it's own tag: pokeire.
The Bokurano and Puella Magi Madoka Magica fandoms due to the fact they're both Darker and Edgier deconstructions of counterpart genres (mecha and magical girl). The fact that Madoka had a reference to Bokurano, which means the writers at least know of the series, doesn't help.
Fans of Voltes V vs. fans of Voltron. Particularly infamous in some corners of fandom, where Voltes V proponents will slam Voltron as a rip-off and dedicate fanfiction and videos to the characters being slaughtered or made out to be villains threatening the Voltes V team. Flamewars will spark over which giant robot would wipe the floor with the other, and whether or not the "Voltron" title plagiarized the "Volt" in Voltes (fans who point out that the original title was Go Lion tend to get ignored in the shuffle). The arguments all boil down to which Five-Man Band series is the legitimate and superior title, whether or not the latter was plagiarism, and if it's possible for fans of either to enjoy both.
In the Spring 2013 Anime season, we had Suisei no Gargantia and the (continuing into summer) Attack on Titan, both animated by Production I.G. Some Titan fans blamed Gargantia for "stealing" some of their better animators and money, resulting in some Off Model scenes and still shots (even though many of those stills originated in the Attack on Titan manga). It didn't help that Titan Episode 6 featured some of the most egregrious stills and "QUALITY", while Gargantia's Episode 6 featured a particularly well-animated bellydancing scene.
It happened with Majestic Prince and Valvrave the Liberator in 2013 as both were mecha anime that premiered on the same day despite have nothing in common aside from being in the same genre and being loaded with Fanservice; MJP fans often take it a step further with claims of how well received their anime was while Valvrave was comparatively panned, and in turn the fans of the other show countered that Majestic Prince sold less copies.
After Valvrave aired it gained heavy panning on /m/, so much so that it even gained an averted rivalry between whether or not it was worse than Gundam SEED Destiny. Destiny haters proclaim it is worse due to switching the main characters at the last quarter, a "flawless victory" style ending, a lack of coherence in plot details near the end, and angsty or poorly written characters (mainly Shinn and Kira, respectively); Valvrave haters proclaim it is worse due to the first half having crippling slow pacing that brought down the second half, many plot twists that amount to nothing outside of shock value (mainly time skips), being excessively mean spirited (especially to its main characters), background characters becoming incredibly important before being killed off, and the main cast accomplishing very little with a high toll while the underdeveloped faction (ARUS) ended up saving the world while the ending credits rolled.
SUV drivers vs EV or hybrid drivers. The later sees the former as wasteful and self-centered. The former sees the later as whiny and effeminate.
The Nissan Leaf Vs the Chevrolet Volt, being they are currently the two main choices for an electric car, the two cars that ranked the highest in safty for 2011, and that the Volt won Motortrend American car of the year while the Leaf won European car of the year, both in 2011.
There's also the issue of whether or not the Chevrolet Volt counts as an "Electric" car, or if it's a Hybrid. Both sides of the argument point to the combustion generator in the Chevrolet Volt vs the pure battery electric Nissan Leaf, despite both having a pure electric drive train. In the end it boils down to the Leaf driver saying "It's not electric, it's just a stupid hybrid." and the Volt driver replying "Is so electric, and the generator give it a further range while still using less gas then a pure gasoline car would!" That's right. Electric car drivers will argue over where the electricity comes from.
Holden vs Ford in Australia - both companies have a long history in the country, and there is also spillover from their rivalry on the racing circuit.
Harley-Davidson Vs Indian Motorcycles. Vicious when both companies where still around, still exists to some degree amoung classic motorcycle collectors.
Also Harleys versus Japanese bikes. The former calls the latter "rice-burners," while the latter says they call them Harleys because they Harley ever run.
Chevrolet vs. Ford is probably the great granddaddy of automotive rivalries in the US, especially for pickups. Foreign vs. domestic used to start fistfights in the 70's and 80's, but that feud has mellowed a bit over time. A bit. "Foreign" cars are still banned from the parking lot of the headquarters of the United Auto Workers union in Detroit, though what's "foreign" and what's "domestic" has blurred quite a bit in more recent times.
Mitsubishi Lancer Evolution and Subaru Impreza WRX STI are obviously this since they're built for WRC, having huge fanbases for each side and famous engine. They're also the ones captured by the tuner markets. However, the rivalry ended in 2014 when Mitsubishi Motors announced the discontinuation of Lancer Evolution line, leaving Subaru alone to develop their own WRX STI line.
The German-made Audi S3 Sedan can be considered a Spiritual Successor to the Mitsubishi Lancer Evolution line, utilizing the similar engine and drivetrain configurations, except it abandoned the huge rear-wing in favor of more-streamlined, Rosemeyer-style approach.
Perhaps the second most enduring example is Marvel Comics vs. DC Comics. Debates on who has the better characters, who has the more well-rounded characters, which treats the talent better, and of course, the inevitable movie successes can get bloodied, and annoying for people who don't care about this sort of thing.
Not as pronounced as it once was but Wolverine fans and Spider-Man fans used to have a hold grudges against one another.
Wolverine fans and The Punisher fans also have one, fueled by that one time their respective writers used to regurally exchange jabs at the other.
Teen Titans vs Young Justice. This one began when DC decided to restore the classic Wolfman/Perez Teen Titans - and did so by taking the current Teen Titans and Young Justice books and merging them together. The transition was, shall we say, less than seamless. Young Justice fans were upset because their Lighter and Softer book had been cancelled, with favorite cast members Put on a Bus, and some of the survivors being written as far different characters. Teen Titans fans were upset because they had also lost favorite cast members (and two of them were killed), and now their book had been taken over by what they considered to be a Spotlight-Stealing Squad, the YJ4. Being upset over the same thing, but for different reasons, a rivalry sparked. Sometimes more fuel gets tossed on the old fire, such as the animated adaptions trading tones, or the New52 having no sign of the original Kid Flash or Wonder Girl.
It's important to also note that most readers (although there are exceptions) are fans of the Crisis and the Post-Crisis universe. However, fans of the Post-Crisis universe are divided over those who think Pre Crisis comics were just as enjoyable as Post-Crisis ones, versus those who think everything Pre Crisis was immature, shallow kiddie stuff.
This dispute is now further complicated by the New52 reboot, which means that the DC Fan Dumb is now divided into three camps: Pre Crisis; Post Crisis, Pre New52; and Post New52.
In the Marvel Universe their seems to be a rivalry at times between the fans that only read X-Men comics, and the fans that read everything else but the X-Men.
Avengers fans vs. fans of Brian Michael Bendis, when Bendis started writing Avengers books. Some longtime fans took issue with Bendis' perceived lack of respect for the franchise. Fan objections didn't seem to hurt sales much, though — when Bendis left the franchise in 2012, he had written the Avengers for 8 years and approximately 232 issues.
Avengers fans vs. X-Men fans, particularly from the X-side, who widely see Marvel as neglecting the X-Men in favor of the Avengers due to only having the film rights for the latter team and manyofitscharacters. In 2012, there was actually an Avengers vs. X-Men mega-crossover.
This has spilled over into the film franchises as well. There's been many a debate over which franchise has the better movies, with many from the Marvel Cinematic Universe side wanting Fox to lose their rights in order to absorb the X-Men into the MCU. Not helping matters was the legal gray area concerning the Scarlet Witch and Quicksilver, two characters synonymous with both franchises. This led to loads of debates over which franchise "deserves" the twins more. Quicksilver in particular has been cast for both The Avengers: Age of Ultron and X-Men: Days of Future Past.
Thanks to X-23 being in the series and their Friendly Fandoms status with Runaways and Academy fans, fans of New X-Men don't hold many warm feelings for Avengers Arena either. Notable that is seems to reach on both sides of their Broken Base - fans of Weir & DeFilipis run hate Arena for the same reasons they hate Kyle & Yost run, while fans of Kyle & Yost run see Arena as shallow attempt at replicating it's sucess that's Completely Missing the Point.
And then there are fans of Deathmatch - Boom! Studios series with similiar premise of superheroes fighting each other to death, that had been announced some time after Arena, leading to many accusations of stealing the idea. Which was unlikely, because Deathmatch appeared way to quickly after Arena, and writer Paul Jenkins said the sole reason he went to do Deathmatch at Boom! was that he thought neither Marvel or DC would let him publish book like this under their banner. Fans of Deathmatch, when faced with accusations of "stealing" from Arena either point out they don't really have that much in common or embrace it and say that yes, Deathmatch does the same thing as Avengers Arena. And it does it better.
Despite being written by the same creator, even some fans of Cable & X-Force hate Arena. It's either because they're tired of having to prove guy who wrote book so bad could also write entertaining X-Book or because Hopeless won Harvey Award for Arena while they feel he should win it for Cable & X-Force. Or both.
Fans of post Annihilation Cosmic Marvel and fans of Jonathan Hickman can get quite vocal against each other. It generally boils down to whether you like Hickman's stories enough to pass on the fact he quickly undid everything Dan Abnett and Andy Lanning estabilished for many characters and teams, that didn't fit his vision.
There is a clear division between Marvel fans who prefer The Sixties Marvel and those who prefer The Seventies and beyond. Stan Lee was the driving force during the sixties with his distinctive writing style. He wrote most if not all of the comics during the early years. There is also the debate over how much Lee actually wrote. The 70s had a new glut of writers such as Marv Wolfman, Bill Mantlo, Chris Claremont, and Steve Gerber, all of whom dispensed with Lee's over the top, hip, chummy style. These writers created a edgier, more adult sensibility and often tackled sociopolitical issues head on. They introduced more subtext and occasional adult language. This would continue into The Eighties where sexual innuendos would start to be introduced. Under Lee, the sixties was mostly limited to superheroes. The seventies also introduced a large number of horror themed and non superhero characters such as Blade, The Punisher, Man-Thing, and of course Wolverine. These writers would also create a rich cadre of complex supporting characters for each title, supporting non-superhero characters being a major deficiency during the 60s. It is also under a different writer (Claremont) that the Lee/Kirby created X-Men went from a failed title to a reimagined hot title. To many advocates of 70s Marvel, Lee's co-creations seem flat and one dimensional. To many advocates of 60s Marvel, the 70s introduced too many violent antiheroes.
You don't even have to leave the Pirates fandom to find a rivalry. Johnny Depp fans love to attack Orlando Bloom fans on some forums, because they think Bloom is trying to copy him (apparently bearing a slight physical resemblance to someone = trying to be him in some minds). And then there's the ship wars that break out over who Elizabeth should have ended up with.
Because they were both superhero movies released in 2008 that became extremely successful, a small rivalry developed between fans of Iron Man and The Dark Knight. While the rivalry seemed to be pretty friendly (most fans were too happy to get two good superhero movies in one year and saw both), a small faction seemed to need to bolster their favorite movie by bashing the other. TDK fans accused IM of being a standard issue Marvel popcorn flick with an over-hyped Robert Downey, Jr.. IM fans hit back by saying that TDK was a brooding, pretentious movie that forgot it was supposed to be fun, and featured an over-hyped (and dead) Heath Ledger.
The original Spider-Man and X-Men films have seen an influx of Dark Knight fans flooding message boards since those movies are often seen as some of the best comicbook movies, regardless if the films are still being made or not.
Avatar and Dark Knight fans have fought over whether or not one film deserved more Oscars than the other (mentioned more in depth below).
And yet another one-sided rivarly has sprung up with TDKS fans trolling The Hobbit-related message boards, apparently since The Dark Knight Rises is geared to be the big film of 2012 alongside ''The Hobbit'. So far, most Hobbit fans seemed more dismayed than anything.
The Amazing Spider-Man is also set to come out in the same season, resulting in Dark Knight fans trolling their boards as well.
At least amongst the IMDb boards, Dark Knight fans have also trolled the boards for The Shawshank Redemption and The Godfather films due to those films being rated very high on that website while The Dark Knight is rated (very slightly, mind you) lower. Fans of those movies seem more befuddled than anything and quickly contacted the admins to avoid a Flame War.
It has now gotten to the point where many fear that this behavior will do nothing but harm the box office returns for The Dark Knight Rises and the popularity of the series as a whole.
Finally, not only do fans of any given iteration of Superman have to put up with fans of the trilogy doing what they do, but also backlash from fans of other trilogies spewing bile over Man of Steel due to its connection with Nolan.
Man of Steel fans vs. fans of the Christopher Reeve movies. One side being a wild pack of ungrateful "highbrows," the other being a beehive full of bitter Methuselahs. Of course, real fa... I mean, plenty of fans like both, but that doesn't matter to the fans engaged in the rivalry.
The success of the Twilight movies comparable to many "boy-friendly" franchises has essentially created a battle of the sexes.
30 Days of Night fans and fans of the director David Slade are now at odds with Twilight fans because he's now directing The Twilight Saga: Eclipse. Twilight fans thinking he's gonna ruin it, while Slade fans think he'll finally make the franchise worth the hype. And there's also a Broken Base regarding the fact that Slade chose to direct Eclipse when he said he didn't even want to touch the franchise.
To a certain extent, 2009's Star Trek versus Avatar fans, due to the latter taking a lot of attention at the 2010 Oscars fans feel was stolen away from Trek. This is mainly the younger fans that Star Trek gained, with its hipper, attractive cast and brisker storytelling, as opposed to Cameron's much longer story and more alien world. And that's before we toss in Avatar's (ultimately lost) rivalry with The Hurt Locker at the Oscars.
...which was filmed by Cameron's ex wife, arguably a huge component in why it won.
Going back to the 1950's, there's always been critical contention over who was the greatest Japanese film director at the time: Kenji Mizoguchi or Akira Kurosawa. Later on, Yasujiro Ozu became known outside of Japan and put a new spin on the debate.
So the question is, 'Is Kurosawa, Mizoguchi, or Ozu the greatest Japanese film maker?' Yes.
District 9 fans and Avatar fans for a variety of reasons. For one, D9 fans prefer the gritty, dark world of South Africa to the colorful, optimistic world of Pandora and think Avatar stole District's thunder at awards shows at the end of the year. Avatar fans counter that it is more realistic in its take on humanity, more emotionally involving, and better produced than D9.
Interestingly, both movies could be seen as a Darker and Edgier or Lighter and Softer take on the other, respectively, which probably fuels the rivalry. (and much overanalysis by film nerds)
Speaking of Chaplin, fans of Buster Keaton have been at odds with Chaplin fans since the Silent Era, with a lot of Keaton fans seeing Chaplin as over-rated because his fame overshadows Keaton's.
Several Youtube comment fights broke out between Christopher Nolan fanboys and James Cameron fanboys on almost every Inception trailer in the weeks running up to the release. This rivalry probably started when The Dark Knight was, in the eyes of many, snubbed for an Oscar nomination, but Avatar was nominated the following year despite also belonging to a usually neglected genre and earned more money, and tempers boiled over when Inception hype reached fever pitch.
And just like Avatar and The Hurt Locker above, Inception fans also hold a grudge against The King's Speech following the 2011 Oscars.
Inception fans also have a grudge with The Social Network fans; they feel that The Social Network shouldn't have won the Oscar for best soundtrack because "it's just 4 notes on the piano".
To a lesser extent Showa Era Godzilla (1954-1975) fans vs. Heisei Era Godzilla (1984-1995) fans. At rare times both types of fans will go after Millennium Era Godzilla (1999-2004) fans, mostly the ones that liked Godzilla Final Wars due to its poor box office reception and lackluster reviews.
Fans that often argue toward one another on how Godzilla's Revenge, Godzilla vs. Space Godzilla, the 1998 American remake, or Godzilla Final Wars as the worst Godzilla movie ever for various reasons all over the place including over used stock footage (Revenge), bad music (Space Godzilla), adaption rape (remake and Final Wars), lackluster action (Revenge and Final Wars), ripping off ideas from other movies (remake and Final Wars), bland story and/or characters (all of them), bad dubbing even worse than usual (Revenge and Space Godzilla), bad updated appearances or the monsters themselves be them new or old (Revenge, remake, and Final Wars).
During the 2014 MTV Movie Awards, there were a rash of small fandom wars between it and Vampire Academy after a Godzilla fand insulted Vampire Academy and it's fans when the vampire movie was beating Godzilla in the polls.
A minor one with Man of Steel, with jokes about how Godzilla's battles with the MUTOs apparently caused less property damage than Superman's battle with Zod.
There's one with Pacific Rim revolving around debates over which stylistic approach is best for a Kaiju film, the fantastical and lighthearted one for Pacific Rim or the realistic and dark one for Godzilla. Although there's a sizeable portion of people -including Del Toro himself- who'd love to see a crossover.
The Godzilla fanbase In general is either friendly with Pacific Rim fans, united in their love of kaiju — or would like them to piss off because Godzilla is a genuine Japanese kaiju property, not an imitation, and would so totally own all the robots and creatures in that film.
Ghostbusters has a rivalry which crosses multiple media: Fans of Columbia's franchise call themselves "Ghostheads," and fans of Filmation's franchise (the one with the gorilla) call themselves "Go-ers." These days, it's less of a rivalry and more of an uneasy alliance.
One of the nastiest: The Illusionist vs. The Prestige. Be careful who you discuss either of these movies with. The argument might lead to IQ dissing. Seriously though, it's impossible to find someone who's a fan of both, even though both movies deal with magicians and revenge plots... They just appeal to different folks. Loving one means hating the other. In fact, your love for one is pretty much defined by how much you hate the other. People pick sides based on which one they saw first, which one they saw in the cinema, Bale/Norton affection, Jackman/Rufus affection, belief that if it has Caine/Giamatti in it, it must be epic... But you have to pick a side.
A minor and friendlier rivarly occured among the filmmakers and fans of the X-Men franchise and Spider-Man franchise since both series kick-started the return of comic book movies for the new mellinium with their second acts often being cited as some of the best superhero flicks ever made.
As with Sony's Amazing Spider-Man films, many fans of the Marvel Cinematic Universe criticize X-Men: Days of Future Past just for existing and maintaining Fox's hold on the X-Men film rights, since they wish the rights would go to Marvel Studios. All the more since the Marvel Cinematic Universe version of Quicksilver already appeared in Captain America: The Winter Soldier and is set to return in The Avengers: Age of Ultron. And then there are accusations of Marvel trying to undermine Fox's success by downplaying its X-Men marketing in the comics and cancelling its Fantastic Four titles, while playing up lesser-known concepts such as the Guardians of the Galaxy and Inhumans that will appear in its upcoming movies.note This is something it isn't doing with Spider-Man, for obvious reasons, but Marvel is known to be on better terms with Sony than with Fox as well. Given that most of these franchise's box office draw comes from movie goers and not comic fans, however, one has to wonder how people got this assumption.
Note that this MCU rivalry is different for X-Men than for The Amazing Spider-Man (which has a Fandom Rivalry with DOFP in its own right). Due to DOFP's very positive reception, the rivalry is less "they're turning the series into a Franchise Zombiejust to hold on to the rights"note a criticism of The Amazing Spider-Man 2 by some fans and more "which Marvel movie series/universe is better".note If you want to get technical, it's also often argued that the concept of X-Men works better in their own universe, since it wouldn't make sense why the Avengers are so respected yet mutants are segregated and hunted — a reason why Simon Kinberg has stated thatFantastic Four (2015) won't take place in the X-Men universe.
A Song of Ice and Fire vs. Sword of Truth. The animosity is mostly limited to the ASOIAF fans, who have made a long-running game of mocking the SoT series, its author Terry Goodkind, its fans, and its similarity to Ayn Rand's Objectivist philosophy (it's notable that George RR Martin is socially and economically quite left-wing). Animosity on the SoT side is mostly limited to reactions against this game.
Also ASOIAF vs. The Wheel of Time. Although the two works are different enough that there are a large number of fans who like both for different reasons.
The Wheel of Time vs. Sword of Truth is far more flammable than either of the above, due to fans of the former accusing the latter of being nothing but a thinly-veiled ripoff.
Sooner or later, someone from another popular fantasy series picks on Harry Potter and its fans.
Some fans of The Dresden Files never pass an opportunity to point out that Harry Dresden would utterly destroy Harry Potter in a fight. Never mind the fact that the only similarity between the two characters that even warrants any comparison at all is their first name.
There was some animosity between Harry Potter and Discworld fans due to a misconception that Discworld character Ponder Stibbons copied Harry Potter, or the other way around. In reality, Terry Pratchett has said that J. K. Rowling is a friend of his. (And besides, Ponder appeared years before.)
Not to mention that the only thing Ponder and Harry have in common is that they are both students of wizardry. And, like 68% of the UK population, wear glasses.
In addition, Sir Terry made some comments criticising an interview with JK that some Potter fans interpreted as being critical of her. Similarly, his jokey line about "defeating evil by throwing a piece of expensive jewellery into a volcano" was seen as a "swipe" at J. R. R. Tolkien, whom he has praised to the rafters elsewhere. Pratchett's fans expect him to be ironic, even about things he likes, but those who aren't used to his style can take offence. And Discworld fans, who strive to be equally ironic, don't always help.
When both Potter and Lord of the Rings had their first movies within a month of each other, many comparisons were made, and battle lines were drawn. The two mentor wizards (Richard Harris and Ian McKellen) even sniped at each other in the press. Arguments over whether Voldemort could beat Sauron crop up, but the heat has largely died down.
When the first Potter film came out, FoxTrot did a week's worth of strips with Jason, already established as a Rings fan, going up against Eileen Jacobsen, who turned out to be a Potter fan. (The last strip revealed that Jason secretly dressed up as Harry and went to the movie anyway.)
Fans of A Wizard of Earthsea, especially since it's got a similar premise. It doesn't exactly help that Le Guin herself has criticized the series.
Occasionally, fans of A Song of Ice and Fire swagger around to a forum or YouTube comments section and proclaim how incredibly superior they believe it is to Potter.
On the whole, for fans of the series mentioned above, the main motive for picking on Harry Potter is usually the fact that it's a children's book series. Or they may be disgruntled with its popularity, which they believe is disproportionate to its (alleged) comparative lack of literary merit and/or good writing.
Thanks to Orson Scott Card's fairly harsh criticism of Rowling for her lawsuit against the Harry Potter Lexicon, a few fans of Ender’s Game have turned against it too.
There was a bit of a rivalry with The Inheritance Cycle, but that died out when people noticed that it was entirely manufactured by the marketers.
There's Potter vs. Twilight. Never has such a fandom rivalry been so whipped up by the media itself. Twilight, like Potter, is something of a literary phenomenon, and its movie stars a Harry Potteralumnus, so the two were constantly compared. They really have nothing in common though, apart from both being children's/young adult's fantasy series.
A more interesting fact is that the Twilight vs 'Harry Potter war was whipped by the media constantly comparing the two, but then spread to the fandoms themselves on it own accord and media fanning the flames to that. Harry Potter fans stated that a war between good and evil was a story much deeper than a teenage romance, the Twilighters claiming their series is "sexier and more mature then HP (sic)".
Made worse, when asked "who would win" with Harry versus Edward, Stephanie Meyer didn't just say "Edward would win due to having Super Speed", she said "Edward would kill Harry because his Super Speed makes him faster than wizards shooting wands at each other. You can't say something like that without Internet Backdraft, folks.
To a lesser extent, Buffyverse/traditional vampires/Anne Rice fans. They seem to imply that a true vampire genre fan could never like the blasphemy of Twilight or the take on the female lead when Whedon created such a strong female. However Whedonesques are usually very civil on expressing their dislike of the saga, while not bashing it or its fans.
Harry Potter fans joined themselves to avoid the Eclipse movie from trending on Twitter on the day of its midnight release.
The Hunger Games fans often find themselves torn in the middle; while many are fans of Twilight due to being recommended by Stephenie Meyer herself, they most often find themselves sided with Potter. There are even "District 9ľ" alliance pages on Facebook.
And then, of course, we always have that small group of pretentious intellectual snobs who believe that kids should instead be reading Carroll and Twain and that adults should be reading Austen and Faulkner.
On the Narnia fans' side, it was primarily caused by the author of His Dark Materials loudly criticizing the Narnia series. You can't say stuff like that without causing a fandom war, folks.
For some time there was an entirely mock rivalry between Isaac Asimov and Harlan Ellison, who in real life were close friends: Ellison brought it to an end, because his regard for Asimov was so great he was worried fans would take the rivalry as real.
Fans of Jane Austen vs. fans of the Bronte sisters. Charlotte Bronte personally never liked Jane Austen's work herself, and many fans of Austen's romantic comedies and the Bronte sisters' Darker and Edgier Gothic romances dislike the other's works.
Within the Cthulhu Mythos, some fans prefer H.P. Lovecraft's original inscrutable, human-morality-means-diddly-squat vision of Cosmic Horror Story, while others have no problem with August Derleth's belated addition of good-vs-evil and four-element themes to the Mythos. Even the "Lovecraft Circle" itself had members who'd argued over this one.
There's a small degree of this between Animorphs and Everworld, due to the fact that K.A. Applegate left to work on Everworld, the Animorphs series was largely ghostwritten, and suffered because of it. Fortunately, nothing gets too overly heated.
The Lord of the Rings fans have had some disagreements with Discworld fans over some comments Terry made that, while they definitely established he was a Tolkien fan, had a bit of a backhanded feel to them. Conversely, some Discworld fans see Middle-Earth as everything Discworld is saying fantasy shouldn't be.
Live Action TV
Babylon 5 vs. Star Trek: Deep Space Nine, on account of B5 fans accusing Deep Space Nine writers of ripping off their show. (For their part, the writers have accepted that they were probably at least "drinking from the same well", as it were.) This one isn't so terrible, as the styles are similar, and less-rabid fans of each are willing to concede that the other is a good show.note B5 fan: "Because it stole everything from our show!" DS9 fan: "It did not!" B5 fan: "Did too!" DS9 fan: "Did not!"... and you can see where we're going with this. Both groups, incidentally, tend to like the rebooted Battlestar Galactica, which can be seen as a refinement of the style these two shows started.
Babylon 5 vs. any Star Trek was commonplace but alleviated somewhat when Majel Barrett appeared in the former.
For that matter, Deep Space Nine fans against any and all other Star Trek fans, the latter saying that Deep Space Nine was an un-Trek like beta test for BSG, complete with space station, Old School Dogfighting, and moral ambiguities and political complications that go against the rest of Trek.
Although that tends to be more one sided with most Deep Space Nine fans being general trek fans as well, the serious rivalry is specifically between the two Contested Sequels of Next Gen, Voyager and Deep Space 9.
Fans of the various Star Trek TV series and movies 1-10 vs fans of the Abrams movie.
Heroes vs. LOST. The former premiered during the latter's third season, widely considered to be the weakest, and pleased many fans by answering the mysteries more quickly. This also angered people who were still sticking with Lost, however, the end of season three and all of season four were considered to have been where the show got its ass together, making the rivalry a battle for philosophies. Heroes fans thinks Lost is cryptic and for posers; Lost fans think Heroes fans are simpletons with short attention spans.
24 and LOST has had an ongoing rivalry that causes many flame wars over at GameFAQs' Broadcast Television board despite the fact that the shows have nothing to do with each other.
The aforementioned 24/Lost rivalry intensified after both shows ended only a day apart in May 2010. 24 fans were especially bitter, because its finale lacked the grand send off and adoration that ABC and the entertainment media gave Lost. As a result, 24 fans made many audacious statements against Lost, which included nasty presumptions against the show's narrative and its finale. Also included was a ludicrous claim that Lost would've never seen the light of day without 24 paving the way for edgy serialized TV, even though HBO accomplished that groundbreakingfeatseveralyearsbefore24 did. If anything, The X-Files and Twin Peaks should be credited for inspiring Lost much more. Most insultingly, some 24 fans even suggested that Lost won't be remembered as fondly as 24, because it has no movie sequel in the works. People who are fans of both shows found themselves between a rock and a hard place during this time.
Since Heroes and 24 are in the same Monday night timeslot, and both employ loads of characters and multiple plotlines, the rivalry between fans of both has become intense. So much so that people who like both are labeled turncoats.
Heroes got brief kerfluffles and hate from the Pushing Daisies fandom too, when Daisies got canceled and Bryan Fuller had to return to Heroes.
One of the oddest examples on this list is a rivalry between fans of Heroes and Studio 60 on the Sunset Strip. The two shows debuted on the same day, one after the other. Within a month, Heroes was getting high ratings and Studio 60 was...not. This led to a lot of Fan Dumb where Heroes and "Stupid Americans" were blamed for Studio 60's eventual demise. This rivalry has died down as Studio 60 faded from memory and Heroes fans became less and less willing to defend it.
The Munsters and The Addams Family rarely share fans. Addams' fans believe the Munsters ripped off their concept, in an unoriginal and unfunny way, while Munster fans claim the Addams are not quirky enough (because they don't have powers) to be considered the true sitcom horror family.
Interestingly enough both shows premiered within less than a week of each other.
In addition, on the same year Williams released the The Addams Family pinball machine, Gottlieb attempted (but failed due to rights issues) to release a Munsters pinball machine, which wound up becoming Class of 1812.
Seinfeld vs. Friends was a big one in the mid-late 1990s. Friends fans, on the whole, enjoy Seinfeld as well, but there's a definite disdain for Friends in the Seinfeld fan community.
Some of the more... committed fans of Law & Order: Criminal Intent fans are passionately either pro-Goren, the show veteran played by Vincent D'onofrio, or pro-Nichols, show newcomer played by Jeff Goldblum. It's made more complicated by the fact that Goren and Nichols eps have different show-runners. Fans also believe the network itself is fanning the flames with its "It's Better With Goldblum" promotional ads.
Whose Line Is It Anyway? has the original British show versus the American version. This is a weird example a) because the British version featured tons of performers from the American version anyway (including Colin Mochrie, Greg Proops and Ryan Stiles), and b) because preferences aren't necessarily divided along national lines — a lot of Americans like the original for the British performers and the loosely-put-together style, and a lot of British people like the American version for being more structured/streamlined/better edited. "Clive vs. Drew" is a major point of contention. One of them is definitely not funny at all... but which one is it?
Late night talk show wars. Letterman or Leno? YOU MUST PICK ONE, OR A CHILD WILL DIE.
When Leno returned to 11:30, forcing Conan O'Brien to Channel Hop, a Jay Leno/Conan O'Brien fandom rivalry has abruptly exploded. Complete with a side of vindication from disgruntled Letterman fans.
There used to be a sort of rivalry between Doctor Who and Primeval — enough that Doctor Who writer Paul Cornell joked that he wasn't sleeping with the enemy by writing a Primeval episode. What made the whole thing strange was that, apart from Time Travel, the two shows really aren't that similar to each other (although there are definitely stronger parallels between Primeval and the Doctor Who spinoff series Torchwood).
The Doctor Who/Primeval thing probably stemmed from the fact that Primeval was intended by The BBC's rival ITV as its direct challenger to the new Doctor Who series and its domination of the Saturday-night family viewing market, just as The Tomorrow People was to classic Who.
The rivalry between fans of New Who and Old Who. Go on any Doctor Who forum you will see wars over which one is better. Old Who fans think that New Who is too dramatic, too emotional, not "Sci-Fi" enough, too angsty, too romantic, etc. New Who fans find Classic Who too slow and boring, too cerebral, not dramatic enough, somewhat sexist in its handling of female companions, etc. Old Who fans seem more vocal about it though. Plus there are TONS of fans who like both.
Within New Who, there's also fans of Russell T Davies vs. fans of Steven Moffat, the two showrunners of the revived series - the former from 2005-2010 and the latter taking over from 2010-present. Moffat fans argue that Davies episodes are too silly, too epic, have too many Deus Ex Machinas and technobabble, are too preoccupied with the Doctor's loneliness and angst, take place on Earth too much... while Davies fans say that Moffat episodes have too many plotholes, too many plotlines that put the Doctor at the center of the entire fate of the universe, aren't emotionally-engaging enough, and that Moffat isn't as good as writing strong female characters. Of course, most fans like both equally.
Fans of The Sarah Connor Chronicles and Dollhouse have lots of animosity between them despite the shows airing back-to-back during the former's second season and the latter's first. It started when Fox canceled Chronicles so that they could continue production on Dollhouse, despite the last few episodes of Chronicles having a significant uptake in quality. Several months after the finale aired, Joss Whedon announced that Summer Glau would guest star in the second season of Dollhouse. Then an article was released in which he said he would've keptThe Sarah Connor Chronicleson the air. Interactions between the camps are still not pretty.
Castle vs. Bones is huge, as there's a lot of viewer crossover in the romantic dramedy procedural demographic. Castle fans declare that the storylines on Bones have gone far downhill in their going-on-six seasons, and Bones fans insinuate that fans of upstart Castle don't care about their show and just watch for Nathan Fillion.
Then there's lead vs. lead. Nathan Fillion versus David Boreanaz, Stana Katic versus Emily Deschanel, Canada versus USA...
Fans of Miley Cyrus vs. fans of Selena Gomez. This extends to the girls themselves, who, in real life, can't stand each other. Miley has taken some nasty cheap shots at Selena, and Selena has essentially admitted that she can't stomach Miley and implied that she is too petty to be worth her time. Rivalry mainly started after Nick Jonas broke up with Miley and started dating Selena, although purportedly he spent his entire relationship with Selena trying to turn her into something she wasn't (namely, Miley.)
The Disney Channel vs. Nickelodeon. Fans of the former claim that Nick has rested on Sponge Bob Square Pants to carry it through and been unimaginative. Fans of the latter claim that Disney is too squeaky-clean, and nothing more than an enormous Idol Singer marketing machine, while asserting that Nick's stars can act and sing circles around Disney's. Of course, most people who grew up watching either channel in the 1990's usually liked both back in the day (they both had completely different target audiences, as in the '90s Disney was more aimed at adults and Nick was more aimed at kids) and dislike them in their current state (today both channels are aimed at tweens over anyone else).
iCarly vs Sonny With A Chance. Many fans of the former see the latter as a ripoff(and vice versa), and rumors are in fact circulating that Sonny With a Chance was ripped off of an idea that developed into iCarly. Both sides claim the other has been ripping off each other, claims that Nick's Zoey 101 was ripped off from Lizzie McGuire, and Disney's Sonny With A Chance was ripped off from the original idea for iCarly.
There's a Nickeldoden civil war between people who like Victorious but never liked or watched iCarly and iCarlys existing fans who hate Victorious. It generally stems from Victorious being produced by the same company, using the same studio, meaning only one can be in production at one time. This immediately sliced iCarly episode runs in half, then Victorious used three of the episodes of the already pitifully small 13 episode Season 4 order to make a crossover that was basically the iCarly characters being guest stars on Victorious.
iCarly casting One Direction as guest stars caused instant drama, mostly on Tumblr. One Direction fans derided the iCarly fandom as being comprised of "immature 12-year-olds" that would somehow swamp the non-12-year-old One Direction fandom, iCarly fans shot back with "who are One Direction and why have I never heard of them?", that iCarly is far more popular than One Direction ever will be, and reminding the One Direction fans that the majority of its fandom are much older due to how long the show has gone for as well as having a lot of mature humour.
Skins vs. The Inbetweeners. Skins also has this between fans of the original British version and fans of the American remake, as well as fans of the different generations of the British version.
An example all from a single TV show: Joel Hodgson vs. Mike Nelson as host of Mystery Science Theater 3000. This one was one of the biggest debates on the Internet during its infancy, and still persists to this day (mostly thanks to Fan Dumb who just won't let it die). Said Fan Dumb often ignores the fact that Mike was the head writer for everything except the Old Shame first season, meaning some of Joel's most beloved jokes were actually created by "that other guy". It also ignores that Joel himself has gone on record as saying he thinks Mike was better, and that if Mike hadn't been a late addition to the team he would have asked him to host from the very beginning. The show tipped its hat to the debate in the 10th season opener Soul Taker, where Joel makes a brief return and Mike feels put out before Tom and Crow calm him by saying "Don't compare yourselves, it ain't healthy".
Now it continues in a slightly different form, as both men have their own Spiritual Successors to MST, Mike's RiffTrax and Joel's Cinematic Titanic. At one point Mike approached Joel about pretending there was a real rivalry between them in order to mess with the fans, but Joel declined.
Farscape versus Stargate SG-1: because the Sci Fi Channel cancelled Farscape and then took over Stargate, with some tactless remarks about the latter show's demographic being more profitable. Calmed down a lot when Ben Browder and Claudia Black, the lead actors from Farscape, joined the regular cast for the final seasons of Stargate, although that caused its own problems between fans of the earlier series who didn't like the Frascape-esque feel of the final seasons, and fans who preferred the final seasons over the earlier ones.
It should be noted that Sci-Fi began airing Stargate SG-1 well before Farscape's cancellation, however. There was much more ire for fans of the remake of Battlestar Galactica, in no small part thanks to the more tactless comments by Sci-Fi channel about the announcement of Battlestar being greenlit because the channel needed a "sexy, dark and edgy space-based science fiction drama"...right as they cancelled their existing "sexy, dark and edgy space-based science fiction drama."
To a lesser extent Farscape vs. Firefly, as both have a number of similarities in being strongly character-driven and arc-based science fiction series set in a Crapsack Universe.
Wheel of Fortune versus Jeopardy! Both shows were created by the same person, are made by the same production team, and air one before the other in most markets (the order depends on the station), but that doesn't mean everybody loves to watch both shows. Even though they're arguably one of TV's most popular program pairs, the games themselves play out quite differently. "Jeopardy!" is more about trivia while "Wheel" is more of a word or puzzle game. The differences between the two shows link to many different views on one show in comparison to the other.
It doesn't help that in recent years, Wheel fans have accused the executive producer of favoritism towards the other show.
Played for Laughs among fans of The Daily Show and The Colbert Report. Being as these are sister shows, aired back-to-back on the same network, with the latter being a Spin-Off of the former, most TDS viewers are TCR viewers, and vice-versa; the difference is really more one of "do you tune in for Jon and stay for Stephen, or do you tune in for Stephen and watch Jon because hey, why not?". However, Stephen Colbert's (in-character) tendency to make a war out of everything has led to some lighthearted rivalry between those who prefer one over the other.
Once Upon a Time vs. Grimm. Never mind that these two shows are pretty much apples and oranges and the only thing they have in common is having a fairy tale theme, fans just can't stop comparing the two and arguing which is better. Fans of the former (OUAT) dismiss the latter show (Grimm) as either having too much of a slow-moving plot, having no plot at all, just being a Monsters of the Week show dressed as a Police Procedural one or being a ripoff of Supernatural. Grimm fans, on the other hand, mock OUAT as being too light-hearted, cheesy, soapy, Disney-fied and being a "chick show".
One particularly sad one, largely based on Real Life events, exists between fans of ten-year-old Shake It Up actor Davis Cleveland and fans of Demi Lovato, largely due to comments made by Lovato in 2011 on Twitter criticizing a joke about anorexia Demi witnessed on SIU. Lovato made a rhetorical Twitter post observing that Disney Channel actresses seemed to look skinnier and skinnier, a comment that, while meant as a general statement, seemed to hurt the feelings of SIU star Zendaya Coleman. Coleman's dad took to Twitter to defend her daughter, asking for an apology, and Lovato offered one and explained she had only wanted to see more diversity and acceptance in body shapes and did not mean to hurt anyone. Davis also seemed to take it hard, defensively and angrily criticizing Demi for her use of drugs and alcohol prior to stint in rehab, and accusing Demi's fans of putting her up on too high of a pedestal. These statements only seemed to inspire Demi's fans to insult and threaten Davis on Twitter regularly. Though Davis and Demi have attempted to move on, there seem to be constant flame wars and drama between "Lovatics" and Davis, and between Lovatics and Davis' fans up to mid-2012. As of this update, said drama and flame wars has long been gone, meaning either one or the other had called a truce offline.
Speaking of Battlestar, some fans of the original series have no love for those of the remake, and continue to believe that Sci-Fi should have made a continuation of the original series as championed by Richard Hatch instead. The teeth gnashing between the two camps began even before the new version even aired, made worse by the fact that Sci-Fi did, at one point, publicly suggest that they would make a continuation before deciding on a remake.
Elementary vs. Sherlock. From the moment Elementary was announced, these two have been going at each other. Both are modernized versions of Sherlock Holmes (which is cause for much of the hate between them - even though Universal's series of movies with Basil Rathbone beat both to the punch in the 1940s), but the similarities stop there due to Elementary taking place in New York, Watson being a woman, and various other details such as previous occupations and the like. However, what didn't help was that CBS had asked the BBC to make an American remake of Sherlock and were denied, so it appeared that they were just trying to jump on the bandwagon that Sherlock had created. Since then, there has been regular bashing of the other fandom on their respective Tumblr tags, each show believing that it is better than the other.
The war even drags fan politics into it, with Elementary fans claiming that their show is more diverse because Watson is an Asian woman, and that Sherlock fans are a bunch of sexists and racists, and Sherlock fans claiming that Elementary turned Watson into a woman because of misplaced Gay Panic, to which there are accusations of queerbaiting. It goes on. Steven Moffat's sizable Fandom/Hatedom does not help.
Then there are the people who mentally block out the other series' existence entirely.
Buffy the Vampire Slayer vs Firefly to some degree. There are plenty of Browncoats in the Buffy fandom, but there is also a faction that hates Firefly because they feel that when Joss Whedon left to work on Firefly, Buffy suffered irreparably.
Merlin and Camelot seemed to have this during Camelot's short run. Camelot fans thought Merlin was bad for not following the legends closely, and Merlin fans didn't think another Arthurian series could be better or get used to new actors in the roles. Granted, part of the difference is that Merlin was written for younger audiences (it's a children's show in the UK) than Camelot.
CSI: Crime Scene Investigation and CSI: NY fans vs CSI: Miami fans. There is a lot of interconnectedness among the franchise fans, and many like all 3 series or get along fine with those who prefer only one or two,but many fans of the other two hate on Miami because they don't like Horatio/David Caruso. Then there are the original franchise lovers who feel the spinoffs could never compare to Vegas.
War broke out in British TV fandom in early 2013 when Downton Abbey won the public-voted National Television Awards prize for best series. Cue outrage from, in particular, Doctor Who and Sherlock fans who believe that their shows are both better and more popular. There was also some outrage from Merlin fans who thought their show was "owed" because it had just finished, although they were at least able to console themselves that Colin Morgan won best actor.
Victorious: Victorians (fans of Victoria Justice) vs. Arianators (fans of Ariana Grande). Despite both girls starring on the same show, a lot of Arianators see Victoria as being overly Adored by the Network, often stating that Ariana is a much more talented. Likewise, a large portion of Victorians can't stand Ariana, calling her "fake" and "annoying", among other things. When Victoria and Ariana had their Twitter fight in early February 2013, tensions between the fandoms escalated to all-out war that lasted several days. It was only during the 2014 Kids Choice Awards had the two posted proof that the feud was done with and are back on good terms.
Adam-12 vs Emergency! to a point. They both like to think their guys are the best looking, and Adam-12 fans sometimes feel pushed aside somewhat between Emergency and Dragnet both being so popular.
The Sopranos vs. The Wire vs. Breaking Bad. All three of these shows are commonly referred to, by critics and audiences alike, as the greatest dramas in the history of television. While each fandom will generally acknowledge the quality of the other two, discussions over which of the three is THE greatest can become...heated.
Fans vs. anti-fans. Anti-fans are disgusted by fandoms, which are generally composed of whiny, emotionally stunted philistines with a tremendous sense of entitlement who are confused and frightened by every new thing in their precious objects of fandom and more interested in belonging to a group than actual art. Meanwhile, fans of all stripes detest a particular culture of smarmy, black-hearted elitist cynics who would rather choke on a barbed wire lollipop than remove the rod from their collective ass and enjoy themselves.
At the time that some people were getting into science fiction fandom more for the social aspects of fandom than because they were into the genre, the expression "We're just fans, we don't read the stuff" appeared. Opponents of those people responded with the slogan, "We're not fans, we just read the stuff."
FIAWOLnote Fandom Is A Way Of Life vs. FIJAGHnote Fandom Is Just A Goddamn Hobby
There also seems to be a Hatedom towards Speculative Fiction (regardless of the medium) from others who like things that are non speculative fiction, like Lit Fic and other medium equivalents for example.
Fans vs fans who write Fan Fiction. If non-fic fans know much about fic-ers they've depicted them as sexually frustrated middle-aged women with too much time on their hands who will pair up anyone with anyone/thing (leading to comments about how "disgusting" fanfic isnote ALL of it). Fic-ers on the other hand bash the rest of the world for "closed minded hate" towards favoured characters or ships, equating a dislike of fanfic with the closeted, agoraphobic nerd who won't remove action figures from the original packaging and is anti-fun. Fic-ers have also been known to get slightly miffed whenever a non-fic-er sociologist or anthropologist tries to "understand" this subculture. For the most part though, both groups casually ignore each other under the mantra that the other just doesn't "get it", and fan fiction tends to remain relatively unknown to the average muggle.
Add to that certain genres of fanfiction that appeal to different types of fans. It depends on the fandom, but generally, it's best to watch for writers of shipping fics vs. writers of grimdark fics vs. everyone else.
Fans of the fantasy series Epic Legends Of The Hierarchs and Song Of The Sorcelatorhate each other, with both sides, authors included, accusing the other of plagarism. So why is this in the "Meta" folder? It's all fake. Neither series even exists; it's just people enjoying making up Stylistic Suck and having mock fights over it.
Spoilers vs no spoilers. Some fans enjoy finding out what's ahead for their favorite shows, while others throw a fit if they find out even a small tidbit about what's coming.
Although mainly because of political reasons (and not on the internet, but rather an actual rivalry, with fighting), traditional Oi! skinheads and antifascist punks vs neo-nazi boneheads (who call themselves skinheads)
Theists vs. atheists. Someone was going to say it.
This also applies to the countless interreligion and intra-religion feuds.
W.E.B. DuBois followers vs Booker T. Washington supporters. Both were early civil rights leaders, but could hardly be more different in their ideas. Washington urged black Americans to learn a trade and become part of the working class, where their buying power would naturally bring them into acceptance within white society. DuBois urged black Americans to study literature and the arts, embrace their cultural roots, and demand equal rights through fierce political action. Washington and his followers argued that DuBois's strategy was too unrealistic and abstract, while DuBois and his followers accused Washington of perpetuating the blacks' low social status.
Among wineries there's Napa Valley vs. France.
Low-calorie fans vs. low-carb fans. (And by extension, saturated fats vs. unsaturated fats, vegetarians vs. omnivores, et cetera.)
Coke fans vs. Pepsi fans.
Who are united, however, against foolish people who insist the drinks taste the same.
The Mickey D vs BK rivalry is as nothing compared to Krystal vs White Castle.
To the extent that there is/used to be a billboard just across the Tennessee/Kentucky state line on I-65 North advertising "Last chance for Krystal" ahead.
Said restaurant rivalry does not apply in the Philippines, where McDonald's has to contend with a certain red fat jolly bee.
Kentucky Fried Chicken vs. Popeyes vs. (if applicable) Churches vs. Brownsnote once again, if applicable, vs. Harolds.
Five Guys vs. In 'N' Out
Domino's vs. Pizza Hut.
And in certain areas, both of them vs. Papa Johns.
White Castle vs Krystal
Cats vs Dogs.
"Normal" pets like dogs and fish vs more obscure ones like rats or iguana
LEGO fans vs. Mega-Bloks and to an extent, Kre-O and, to a lesser extent, LEGO fans vs. all other building block toys. Not sure how strong this is on the non-Lego side, but on at least one Lego fansite, the names of other brands like Mega-Bloks and Tyco are used as replacement swearwords.
X political party and Y political party, anywhere. It's particularly pronounced in America with the two party system.
America actually has more than two parties but you probably wouldn't know that since only the Democrats and Republicans ge tany attention. This leads to the always painful liberal vs. conservatives.
And within the Republican party, moderates vs. Tea Partiers. It's gotten to the point that unity events are being canceled. And of course the Tea Partiers are just going to fire up the Democrats in November.
In America, the rivalry may exist more due to problems of in-group/out-group identification than actual differences, making this a sad case of manufactured rivalry.note There are two views of party composition: either bipolar (two huge blocs at each side of the spectrum and a small number of independents/undecideds/apathetics) or unipolar (traditional bell-curve: the majority of people fall somewhere in the middle, and as you move toward the extremes of either side, numbers drop off). Each view favors different strategies — if you believe the bipolar model, you antagonize your base by driving them to the polls for state issues (this was Karl Rove's strategy in 2004, when many states voted on gay marriage); if you believe the unipolar model, you build a platform around appealing to as many people as possible and avoid extreme stances. The problem (and rivalry) can be partly explained by the fact that the most extreme voices are often the loudest and election math: not every district is hospitable to moderation, nor is every state. What helps a candidate win a Senate seat in California may backfire spectacularly in Ohio. House races are even worse due to gerrymandering. State races are also tricky, as "conservative" and "liberal" vary by location, and sometimes state officers (particularly governors) are put in a position where throwing the national candidate from their party under the bus is the better move. This is one reason candidates have an incentive to favor rhetoric over actual policy proposals. Third party candidates often criticize Democrat-Republican races as a choice between the same thing in different packaging.
Railfans tend to strongly dislike Busfans and bus transportation in general due to the mostly correct perception that buses killed the majority of streetcar, commuter and long distance rail passenger services across North America. Most railfans will choose to walk long distances to avoid having to ride a bus.
Similar to the bus issue, some railfans (or people who just prefer traveling by train) will hate airlines because they think flying is a bigger hassle than rail travel or because in the second half of the 20th century the rising popularity of airlines resulted in a major downfall for passenger rail service.
Union Pacific vs. Burlington Northern Santa Fe and CSX vs. Norfolk Southern, especially their predecessors and purchased railroads. Also other smaller/defunct railroads vs. the aforementioned railroads.
New York Central vs. The Pennsylvania Railroad is still a big one despite both railroads being out of business since 1968.
EMD vs. General Electric Transportation vs. defunct locomotive manufacturers (Baldwin for example).
Knitting and crochet. Seriously.
And in each of those, but especially in knitting, natural-fiber versus novelty-yarn.
In the US debates rage between fans of the AK-47 (and to a lesser extent, other AK derivatives) and the M-16 (or the civilian version, the AR-15). This is also partly due to the huge political and cultural aspect, as the AK has been often the gun of America's enemies, like the Russians and other communist countries, while the M-16 has been the gun of America. That AKs were used against M-16s in the Vietnam War also is a big point, often brought up in debates/flame wars.
To a lesser extent, shotgun fans are divided between Mossberg and Remington, especially for pump-action, and there is further debate between the whole pump vs break open (double-barrel or over-and-under).
Obligatory hentai examples:
Yaoi fans: There are the ones who like the effeminate boys, and the ones that like muscular guys.
Yuri fans vs yaoi fans. Even at times, male yuri fans vs female yuri fans.
And of course Rule 34 vs. fans who don't want to see their favorite shows as sexual.
Not even theoretical physics is immune from this; the most famous example (currently) is proponents of string theory vs. proponents of other theories, with the latter accusing the former of playing unfalsifiable, unscientific mathematical parlour .
Every science has this, in fact. For example, psychology had psychoanalysis vs. behaviourism at its outset, then behaviourism vs. cognitive psychology, then all of the above vs. evolutionary psychology and so on. And then there's hard (natural) science vs. soft (social) science, with people in the hard sciences accusing their softer brethren of being pseudosciences and people in the soft sciences accusing them of being smug elitists in turn. And then there's science people vs. arts people, whom they accuse of getting A Degree in Useless.
While on Hard on Soft Science, college students might get into some heated arguments: exact sciences vs. human\social sciences, exact sciences vs. biological sciences, law school vs. the other humanities...
When Brazilian movie magazine SET was sold to a different publisher, one of the editors started his own publication, Preview. Then his old boss returned to SET. The magazines have since started a rivalry, particularly fueled by the fact that SET suffered from chronic Schedule Slip until it ceased publication (Preview fans even call her "The Dead One").
As mentioned in the Sports section below, St. Louis and Chicago already have a baseball rivalry but this extends to the two cities themselves since they are basically the two major cities fighting over the center of the country... Kansas City being a possible third option.
Boeing vs. Airbus. This one's realSerious Business—after all, the former's biggest fanboy is a certain scholarly gent who goes by the name of Uncle Sam, while the latter has a major fangirl in Europa (no, not the moon of Jupiter). Boeing fans claim Airbus is an upstart company with a crummy name, that gets an unfair leg up with preferential loans from the EU. Airbus reply that Boeing is Not So Different, and is only kept afloat by Pentagon pork and US diplomatic pressure on countries to make their flag carriers buy it. Of course, this mirrors the fact that the companies themselves utterly loathe each other, to the extent that Boeing ignored Airbus's warnings over the 787 battery fiasco, believing them to be a sneaky plot. This rivalry ranges from mutual bitter WTO disputes, to hilariously bitchy advertisementwars.
Aviation enthusiasts also do this with airlines: United vs. Delta, British Airways vs. Virgin Atlantic, etc.
Reason vs FL Studio vs Ableton Live vs whatever other DAW.
In the dinosaur fanboy community, one of the biggest debates involves who would win in a fight between Tyrannosaurus and Spinosaurus (two of the largest carnivorous dinosaurs), with both sides involving fanboys who constantly think of reasons that their theropod is bigger or stronger while bashing the other. The feud probably started because the Spinosaurus replaced the T. rex in Jurassic Park III. Things get worse when the carcharodontosaur Giganotosaurus gets involved, with fanboys practically doing the same thing as the other two carnivores. In fact, it would probably extend to a battle of any of the largest carnivorous dinosaurs.
Hardcore palaeontology enthusiasts vs. people who like featherless dromaeosaurs (and other dinosaurs which have proven to have been feathered). The former just want media portrayals of prehistoric life to be accurate, but the latter will try and think of excuses to make sure that the dromaeosaurs remain scaly because that is how they prefer them to look (despite quite a few of them not having the best scientific knowledge).
Palaeontology fans vs. cryptozoology fans. Some try to find a healthy balance, but sadly the majority of paleo-nuts like to call crypto-nuts "delusional", while crypto-nuts call paleo-nuts "closed minded".
Related to various parts of the the above, evolutionists/Darwinists(specifically macroevolution-natural selection/speciation is accepted by pretty much everyone.) vs creationists. Intelligent design is somewhere in the middle, accepting macroevolution but with a religious overtone. Often, though, people forget there are plenty of old earth Christians out there, simply equating accepting evolution with being an atheist, even though it's often not true.
In the world of pinball, Williams Electronics vs. Midway Games vs. Data East, even after Williams bought Midway (Bally was its pinball label) in 1987. When all three left the pinball business in 1999 leaving only Stern Pinball (see above), fans of all three companies ganged up on hating Stern and its fans.
In the roller coaster industry, there are several: for steel coasters, there is Bolliger & Mabillard vs. Intamin, and Schwarzkopf vs. Arrow Dynamics. For wooden coasters, there is the Gravity Group vs. Great Coasters International vs. Rocky Mountain Construction.
Krispy Kreme versus Dunkin Donuts is a common debate. Don't get Starbucks or Tim Hortons into the argument or you'll really have a brawl.
From within the WWE itself are Raw vs. Smackdown (the flagship sports entertainment show vs. the wrestling show, made worse when the Draft often relocates a lot Smackdown talent to Raw), brand extension fans vs. unified company fans, Cena fans vs Cena haters, Superstars (especially Divas) with indy wrestling backgrounds vs. WWE/NXT homegrowns, Jim Ross vs. Michael Cole, and combinations of the WWE's different eras (Rock and Wrestling vs.The Wrestling/Monday Night Wars/Attitude Era vs. Ruthless Agression Era vs. WWE Universe Era)
Also, Shawn Michaels and Bret Hart has finally settled their differences, but that doesn't stop their respective fans from engaging in flame wars regarding who was better.
People who agree with WWE regarding making Chris Benoit an Un-Person and those who want him in the Hall of Fame and his matches on DVD.note There was a Benoit DVD, 2004's Hard Knocks: The Chris Benoit Story. WWE took it out of print following the tragedy.
Dungeons & Dragons fans and The World of Darkness fans dislike each other. The former see the latter as a bunch of mopey goth LARPers, and the latter see the former as a bunch of ignorant fanboys that can't grasp complex characters.
Warhammer Fantasy and Warhammer 40,000. Fantasy fans tend to look down on 40k fans because they consider 40k to be be "dumbed down", while the 40k fans consider fantasy to be duller than 40k and having some needlessly complex rules. Lots of people still play both, although they tend to play one more than other.
Occasionally joining forces to bash the players of third Games Workshop's game, Lord of the Rings, as playing kiddies' game.
Of course, this gets extra stupid when much of the fanbase plays both, many of the parts and models are interchangeable, and they're all made by the same company. But that doesn't stop anyone.
When it comes to different companies, it can get even worse. One of the relatively notable cases is the Warmachine games vs. the Warhammer games. Expect to see "Page 5" and "GRIMDARK" thrown around if the two groups have "discussions".
Magic: The Gathering and Yu-Gi-Oh! players tend to regard each other with disdain, with the latter having been the former's biggest (and longest-lasting) rival. Yu-Gi-Oh fans often call Magic out on new players being Locked Out of the Loop and the various Loophole Abuse by players, while Magic The Gathering fans tend to call Yu-Gi-Oh players childish and simplistic. There are fans of both games, but they are few and far between.
In Germany, Dungeons & Dragons (being the most popular RPG worldwide) vs. The Dark Eye (being Germany's most popular RPG). Though there is some overlap to be expected (plenty of D&D players started with TDE), the fundamental gamestyle and setting differences lead to a lot of discussions which system is actually better. Whether it's the one of the other is mostly down to one's preferences.
Another legendary fandom rivalry: Mac vs. Windows. Embodied and parodied in Apple's "I'm a Mac and I'm a PC" commercials. This also leads to a false conception of computer history of being mainly composed of Apple and Microsoft, and idolizing their CEOS.
Those commercials are entirely biased towards Macs, as expected. How much Apple plays up the Mac's good qualities and exaggerates a PC's bad qualities is open to debate, though there are one or two more heavy-handed commercials in favor of the Mac.
Even though those commercials do have rather a Misaimed Fandom that sees the PC (played by John Hodgman in the US and David Mitchell in the UK) as a goofy, loveable underdog, while the Mac user is a posing hipster.
Even the ads themselves have recognised this and moved into Friendly Rivalry status.
And earlier than that was 8080/Z-80 vs. 6800 vs. 6502 vs. 1802 in homebuilt computers.
It's not just bad enough that the Linux fanbase is in rival with the Mac and Windows ones, but is actually divided on several grounds itself. Debian vs Red Hat vs Slackware (and by extension, DEB package management vs. RPM package Management vs. TGZ package management), KDE vs Gnome (and KDE4 vs KDE3/Trinity) versus every other desktop environments out there, vi vs emacs vs nano, Copyleft licenses such as GPL vs permissive licensesnote e.g. Apache, PHP, MIT and BSD licenses, etc...
Adding to this are the "Browser Wars" with the heavyweight fight being between Microsoft's Internet Explorer and Mozilla's Firefox. A smaller war between Firefox and underdog Google Chrome is also ongoing. Opera and Safari have smaller fandoms who are against everyone at once.
Even within Mozilla, there's a large split between those who want individual programs doing specific things (ie. Firefox+Thunderbird+Kompo Zer) vs. those who want everything in a suite (read: Seamonkey). Heck, even Firefox has a split fanbase and has spawned several forks!
It isn't just software. There's Intel vs. AMD for x86 CPUs and AMD vs. Nvidia for graphics cards with the big ones, and more than likely much smaller feuds between vendors. Hard drive vendors used to be a big one, with the main camps being Seagate, WD and Samsung fans, with Lies, Damned Lies, and Statistics employed throughout. The rivalry with power supplies, memory, and motherboards to an extent have died off. It's usually "just pick something from these companies".
Hard drive rivalry, however, is still pretty much vocal, with the only three groups remaining (Western Digitalnote who bought over Hitachi, who bought their hard disk business from IBM. Did we mention that Hitachi is the black sheep of the hard drive world except to it's small handful of fans?. vs Seagatenote who previously bought out Conner and Maxtor, the latter who bought out Quantum, and Toshiba-Samsung Storage Teechnologiesnote who previously also competing with each other and everyone else, but decided to team up when both their drives started falling behind in sales). God help you if you're one of those who believed that the three brands are equally good- the fandom won't have it the other way and both will barbecue you alive if you don't pick sides.
Don't forget the IBM PowerPC vs Intel Pentium feud... though this one pattered out a bit out once Apple switched from PowerPC to Intel chips in 2005, but not before causing several small wars in the process, and causing a split in the Mac fandom itself. Even today there are still Mac enthusiasts arguing over whether Apple should have stuck with Power-based Macs or if the move to Intel was a good choice.
iOS vs. Android. The rivalry can make it hard to publicly admit having problems with your mobile device without being met with comments like "just switch to <other platform>!"
And that's not all, whenever a chance arrives, both sides often take swipes with each other as much as possible.
Fans of Blackberries (aka Crackberries) vs. both Android and iOS. Even within the Blackberry fandom there's a split between Blackberry Classic and Blackberry 10. note In case you're wondering where the Windows Phone crowd fits into all this, so far they're pretty quiet and thus left alone by the other three feuding groups.
Application and game programmers have sometimes arguments of what engine/code language is better. Some examples:
Flash vs. HTML5.
Java Applets vs. Flash back in the late 90s and early 2000s. Although the acquision of Sun by Oracle and the constant exposure of exploits in the supposedly secure runtime in recent years has made Java Applets mostly relegated to corporate intranets and specific websites.
UDK (a free version of the Unreal Engine marketed towards Indie developers) vs. Unity (another free/low-cost engine that is also marketed towards Indie developers)
Irrlicht vs. Ogre3D
Kinect vs. Move vs. Wiimote.
Code::Blocks vs. Dev-Cpp.
C# vs. C++ (barely a rivalry, but it does sometimes happen)
Java/C# vs. every other language ever.
Java vs. C# is also quite common, too
Visual Basic .NET vs. people who think it is outdated.
Visual Basic .NET vs. classic BASIC (all caps, since it's a acronym).
GOTO and GOSUB-RETURN vs Object Oriented Programming. While this rivalry is rare nowadays as the latter is now universally accepted and the former is only still relevant in Assembly Language, through the 60s and 70s this was a war fought between two very vocal programmer groupsnote The group backing GOTO are those who believed programming languages should be left to real men and that people who cannot grasp the concept of GOTOs, tight optimization and self-modifying code are not worthy of being called a programmer, while the latter group believes that code should be clearly written and easily debugged at the expense of processing complexity, arguing that computing power doubles every 18 months anyway. The arguments put forth by the former can be found in an essay called Real Programmers Don't Use Pascal which is widely available online. The arguments put forth by the latter can be found in the article Goto statement considered harmful.
SQL vs. Access
SQL server vs MySQL vs other Database server softwares.
MySQL vs PostgresQL is another common one among open source fans.
.NET programmers (and the Microsoft stack in general) vs various open source communities
Building on this, Visual Studio (Microsoft's development IDE) vs. Eclipse vs. every other IDE is quite common
Perl vs. Python vs. TCL.
vBulletin vs Invision Power Board vs Xen Foro. Fans of one tend not to be fans of the others and there's quite the argument over which is better forum software. Same goes for phpBB vs My BB vs SMF in the free forum world and free forum software vs paid forum software in general.
This rivalry likely crystallized in the 1980s - Sondheim's shows won critical raves, numerous Tony Awards and even the Pulitzer Prize. Webber's shows made lots of money and developed enormous fanbases, as well as won a few Tonys of their own. Sondheim's seen as smart and meaningful by lovers, cold and difficult by haters ("the songs are absolutely unhummable!"); Webber's seen as emotionally thrilling by lovers, shallow and dumb by haters ("you walk out whistling the sets and costumes.") The 1988 Tony Awards may perfectly encapsulate this rivalry: Into the Woods won the Book and Score awards, but The Phantom of the Opera won the Best Musical prize.
Weirdly, though, the fandoms for the film versions of each of Sondheim and Webber's magnum opuses (Sweeney Todd: The Demon Barber of Fleet Street and The Phantom of the Opera, respectively, which were filmed within three years of each other and both produced by Warner Brothers) overlap pretty strongly, much to the chagrin of the stage fandoms for either musical, who tend to view both films as inferior compared to their sources.
Oh, but it gets worse. The stage-purist Todd fans are pretty divided over the original full-scale production and its symphonic spinoffs and the tiny, spare, 10-actors-playing-their-own-score production mounted on Broadway in 2005. Defenders of the original production call it a full-on Guignol-style thriller with sweeping music rendered beautifully by a full orchestra that gives richness and complexity to the score, while calling the mini-version a tasteless, pointless exercise in distracting Brechtianism that robbed the music of its depth. Fans of the 2005 production will say that their favorite version is a sexy, vicious little dark jewel of a show while the original was a cartoon full of exaggerated acting and (similarly to criticism of Webber's work, ironically enough) reliance on spectacle.
If you leave Sondheim out of the picture, there's still Andrew Lloyd Webber vs. Frank Wildhorn, whom even people who don't particularly like Webber's works have characterized as an untalented pretender to Webber's throne. Wildhorn's own fanbase adores him and will defend him to the death against basically every other composer out there.
Similarly, Stephen Sondheim vs. Jerry Herman fans. Jerry Herman fans tend to site Sondheim as "unhummable", "depressing", or "pretentious", while Sondheim fans tend to say Jerry Herman's stuff is "saccharine", "too cute", and "frivolous". Again, this is encapsulated in the results of an awards showdown: In 1984, Sondheim's Sunday In The Park With George was successful enough that it won the Pulitzer Prize for Drama the following year...but in the meantime got curbstomped at the Tony Awards by Herman's La Cage aux folles.
Classic musical theater fans (Oklahoma!, West Side Story, My Fair Lady, that sort of thing) vs rock/pop musical fans. Some classic fans will admit to liking Hair, Godspell, and maybe — at a stretch — Rent but that's about as far as they'll go.
Jesus Christ Superstar: Fans of the original 1973 movie vs. fans of the 2003 movie. Hippie Jesus vs Possibly Gay Ghetto Jesus? Decisions, decisions...
Also, Murray Head as Judas (the original concept album) vs. Carl Anderson as Judas (the 1973 movie). And no, you may not answer Jerome Pradon.
Speaking of Phantom, its fandom does not like High School Musical very much, possibly due to the latter taking a snipe at Michael Crawford, the original Erik in the stage production and regarded as basically a saint in Phantom fandom.
Tanz der Vampire versus its short-lived American counterpart Dance of the Vampires. Notable in that even the composer himself has called Dance "utter shit" on his blog. Still, there are fans out there who like the American version for taking itself less seriously. A happy minority tends to simply sit back and explain that they think both versions have their high points.
An example from a much earlier period in theatre history: Al Jolson vs. Eddie Cantor.
Edwin Forrest and William Charles Macready, two rival Shakespearean actors from the 1840s. Read about them at this Cracked.com article.
Richard Wagner v. Giacomo Meyerbeer (Or Richard Wagner v. Johannes Brahms)
On the topic of My Little Pony, one of the earliest battle-lines drawn was Bronies vs. old-time Collectors who collect G1/Tales/G3 toys for the sake of their love for little plastic horses. Many Bronies have nothing but contempt for pre-G4 figures, while said collectors diss G2/G3.5/G4 figures for not looking like horses. Needless to say it's quite rare to find people in these two camps that even talk to each other, much less actually get along.
Then there's bronies who only collect show-accurate (non-Hasbro made) G4 ponies vs. the other G4 pony collectors. The former complain about how Hasbro's products do not look like in the show and buy ponies from show-accurate toy licensees like Funko and Build-a-Bear, but never from Hasbro themselves. The latter thinks that the former is completely missing the point of collecting MLP, believing that since the franchise belongs to Hasbro, one should only be buying Hasbro ponies.
Bionicle vs Hero Factory, even though one was the replacement of the other. Bionicle fans hate Hero Factory for replacing Bionicle, and being more simple and childish, while Hero Factory fans think Bionicle is overly complex and doesn't allow room for new fans
4chan and Reddit. In all fairness, the rivalry is a bit one-sided, Reddit seems to have some respect for 4chan, despite what comes out of there on a regular basis, whereas 4chan dismisses Reddit as a hipster and ultra-liberal circlejerk that ruined memes such as rage comics.
This is due to the view of Reddit's detractors that Reddit's content is primarily gags and memes stolen from 4chan and driven into the ground (not to mention missing the point of said memes, robbing them of context necessary to the joke in the first place).
It's gotten to the point where 4chan, or at least certain boards, have essentially renounced memes, and are vehemently opposed to them as a concept, just because Reddit likes them. The creation of new humorous content is discouraged, just so that Reddit doesn't get anything new to steal.
It has since evolved into 4chan vs. Reddit vs. 9gag. Where Reddit takes memes from 4chan and runs them into the ground, 9gag takes those and then slaps their watermark on it. Combine this with 9gag being connected to social media sites like Facebook has lead to the mainstream media to believe that 9gag created these memes. It has lead to both 4chan and reddit working together to attack 9gag as well as 4chan conducting solo raids on the site. Just mentioning 9gag on any board will result in the thread being saged into oblivion.
It isn't Reddit vs. 4chan vs. 9gag anymore. It's Everyone vs. 9gag now. 4chan and Reddit (when they aren't taking pot shots at each other) are not above putting aside their differences to enact a joint raid on 9gag. Case in point, the 4chan—Reddit—Funny Junk—Tumblr coalition enacting Operation Deepthroat.
4chan and Tumblr. Tensions were cooled somewhat when the anthropomorphisms of the latter and Anonymous were shipped together. It's still one-sided to this day, however, with Tumblr holding respect for 4chan and 4chan dismissing Tumblr as an ultra-feminist hipster circlejerk filled with social justice warriors and very vocal fandoms that ruin everything.
Their fans, especially fans of Mr. Plinkett, have a rivalry with fans of the Star Wars prequels. This is because Mr. Plinkett gave the prequels very in-depth negative reviews which attracted Star Wars prequel anti-fans to his videos. In fact, his reviews of the prequels are his most well-known due to being shown on Roger Ebert's website (who gave Revenge of the Sith a positive review) and tweeted by Simon Pegg.
Both The Angry Video Game Nerd and The Nostalgia Critic got very tired of the Fandom Rivalry that sprouted among people too stupid not to realize that their satirical feud wasn't Serious Business, and soon new videos on the subject started to become more and more blatant about how they enjoyed each other's work and co-produced the competition just for laughs, in advance of angry commentors.
On the other hand, most serious fans of the Nerd really do hate The Irate Gamer, who is seen as being an inferior rip-off and not confessing to such. Not to mention his Small Name, Big Ego
The Nerd's FANS? Several of Rolfe's friends tore into Irate Gamer pretty bad in the AVGN comedy roast, so much so they spent almost as much time calling him a ripoff as they did staying on topic.
In Germany, it's Coldmirror fans vs. Die Außenseiter fans, both comedians on Youtube.
In Italy, there's the whole Yotobi debate. Youtube users SereINC and 2blugori have provided well-done Fan Subs for the aforementioned Nostalgia Critic; however, many videos get often thrashed by Yotobi fans, as if the Nostalgia Critic stole Yotobi's source material. Italian NC fans usually snark at them by shrugging every insult off, while calling them nothing more than "Yotobi fanboys". Hell, some of them even say "Yotobi fanboy alert" whenever one of them pops up. Nevermind the two Video Review Shows are next-to-nothing alike.
Ben Rants/Benthelooney fans hate The Rowdy Reviewer because of the way his voice sounds on camera, and the fact that he mostly reviews things he grew up with and the way he voices his opinions, and The Rowdy Reviewer fans hate Ben Rants because of the way Ben voices his opinions, his retcons (Making his avatar into a cartoon character, contradicting previous opinions: Ala in the original and first run, he stated he was a 90s kid but in the revival, states he's a 2000s kid) and having at least more than one joke in every video since the revival.
In real life, a vocal portion of UFP's fans hate Friendship is Witchcraft and feel the need to post youtube comments to that effect on the UFP videos. Not a large portion, mind you, just an annoyingly loud one. UFP actually has a few Take Thats towards FIW, but UFP creator Wacarb clarified (probably to discourage the haters among his fans) that he actually likes FIW and only pokes fun at them out of professional rivalry. Either way, the Friendship Is Witchcraft fandom doesn't seem to have noticed.
Whilst it's true that the other side doesn't argue that much about it, there is still a persistent rivalry between youtube ranters and let's players. Youtube ranters and their fans often complain say that let's players are unnecessary and a waste of time (because why would they watch someone playing a video game if they can play the same game at home). Fans of let's players however still watch them despite it because they can learn more about the game and let's players can give some fun commentary.
It's not a suprise that most of the hatred is directed towards PewDiePie. He's the most famous guy to hate on because they can still be sure that their channel gets a lot of views because of it. The typical accusation directed towards him is however a broken argument he once said, which goes like this: "If you don't like it, don't watch it" and which his fandom keeps shouting at the haters, despite the fact that most of them don't even know what they are saying.
The entire Internet vs. furries.
The furry thing can be split even more: those who prefer clean, non-sexual furries and the hentai yiff crowd.
People who like humanoid characters vs feral ones.
Bronies vs. the internet. Or Furries and Bronies. See the page on the Furry Fandom for some elaboration on the Bronies vs. furries.
Though it's not universal among fans, it is official in a sense that an executive who worked on WITCH derided Winx Club for being produced quickly, stealing the spotlight from his own show and leading ultimately to its cancellation.
Traditional (hand-drawn) animation Disney fans vs. CGI Disney and/or Pixar fans. Yes, this rivalry does exist, largely because traditional Disney films fell into a Dork Age as Pixar picked up a head of steam in the new millenium, to the point that Disney shut down the traditional unit after Home on the Range in 2004. Add to this that the Pixar films have generated a lot more merchandising, theme park attractions, Oscar nominations and wins, etc. than more recent "in-house" efforts have. Ironically, Disney returned to traditional animation thanks to Pixar head John Lasseter encouraging it. Fans cheered the arrival of The Princess and the Frog in 2009... then watched aghast as it was swiftly overtaken at the box-office in favor of James Cameron's Avatar, the Sherlock Holmes film and (most humiliatingly) Alvin and the Chipmunks: The Squeakquel, so this rivalry is only likely to worsen.
It has been asserted (by industry insiders) that Jeffrey Katzenberg formed Dreamworks for the express purpose of taking Disney down after being passed over for promotion by then-CEO Michael Eisner. (No word on any vendettas behind Steven Spielberg's or David Geffen's involvement, though Spielberg did have a major falling out with Eisner around the same time...)
Many Avatar: The Last Airbender fans hate Sponge Bob Square Pants and vice versa. Perhaps it's because the two shows air on the same network yet represent the opposite extremes of the approaches one can take in animation. As master Pakku told a student at the end of the first season of the former, "A couple more years, and you might be ready to fight a sea sponge." Things escalated when Nick developed a bad habit to switch Avatar's timeslot and replace episodes with ever more episodes of SpongeBob instead. This tended to irritate Avatar fans, particularly when the powers that be had an even worse tendency to go on several month long hiatuses with no news on when the show could be expected back on - while airing new episodes of SpongeBob! The two fandoms had a chance to be literal rivals in the 2008 Kids Choice Award for Favorite Cartoon; Avatar won, giving "SpongeBob" its first ever loss in the category, but 2009 just added fuel to the fire when SpongeBob was renominated but Avatar wasn't despite winning the previous year. Unsurprisingly, SpongeBob won and has yet to be defeated again. (Obviously, this looks like the works of the sponge's marketing machine again.)
Fans of Invader Zim sometimes have the same attitude towards Spongebob for similar reasons: IZ's dark comedy is largely contrasted to SB, and IZ got canceled right around the time it was showing signs of developing its own Myth Arc as opposed to its earlier random humor. The Zim fans also seem to hate The Fairly OddParents because it debuted the same day as Zim, and ended up lasting longer (Even though The Fairly Odd Parents was cancelled and uncancelled twice, which is something not alot of people know).
Avatar: The Last Airbender vs. Xiaolin Showdown; maybe because they both have similar characters and have characters that have elements. Ironically, Grey DeLisle voiced in both shows, as Azula in the former and Kimiko Tohomiko in the latter, concidentally enough: both characters have fire powers!
The Simpsons vs. Family Guy. The former openly accuses the latter of plagiarism while the latter accuses the former of being played-out and unwilling to push the envelope anymore. Fans have followed suit.
And Family Guy vs. South Park. There's apparently a friendly feud between the writers of the two shows, but naturally, the fans have taken it way too seriously and way too far.
Interestingly, "Cartoon Wars" was inspired by a lack of Fandom Rivalry – Matt and Trey (who openly hate Family Guy) were sick of hearing people say that "South Park and Family Guy are the best shows on television". Basically, they were offended that their show was being put in the same category as a show they considered to be vastly inferior. So, an interesting case where the creators actually actively cultivate (and canonized) said rivalry.
There's also a political element to the rivalry. Matt & Trey are card-carrying conservative libertarians while Seth MacFarlane is an infamous Hollywood Atheist.
Fans of American Dad! generally wish Family Guy would just disappear, as the former is seen as a rip-off by Family Guy's fans, and as "Family Guy 2" by Family Guy's detractors.
There's sort of a faux-feud between Family Guy and Robot Chicken, as they represent different parts of the adult animation spectrum, but it's only played for laughs, since Seth Macfarlane frequently voice-acts (even cameos) on Robot Chicken and, well, Seth Green gets a huge chunk of his income from Family Guy.
On the subject of Cartoon Network, there is a rivalry between the Ben 10 and Generator Rex fans, mainly because both shows were created by Man of Action. This rivalry is clearly evident in the late Dwayne McDuffie's own forum, and the eventual crossover between the two shows added more fuel to the fire.
Then Generator Rex was canceled early in 2012, and Man Of Action announced a third Ben 10Sequel Series, Ben 10: Omniverse. Cue Ben 10 fans happy to see them working on the show again and Generator Rex fans complaining that they'd rather see the time and money go to a fourth season of Generator Rex.
Phineas and Ferb provides an in-universe example in the episode "Nerds of a Feather," where fans of the boys' favorite sci-fi and fantasy movie franchises are at each other's throats. And can we say totally awesomefight music?
My Little Pony: Friendship Is Magic is, due to its large and extremely vocal Periphery Demographic, an almost literal lightning rod for nearly every other contemporary cartoon. The overall reputation the die-hard "Brony" fanbase has developed since late 2010 doesn't exactly engender favorable feelings from other fanbases.
FiM and Transformers Prime seem set to have one of these, judging by the fandom (or rather, Fan Dumb)'s reaction to Prime getting nominated for six Emmies while FiM had two nominations in the Best Original Song category.
FiM vs. any other show on The Hub. Every time that The Hub's Facebook page makes a non-Pony post, Pony fans complain about the fact that it isn't a pony post. Which leads non-Pony fans (and Pony fans who don't want to be seen as jerks) to defend it, Pony fans not listening, and neither side getting anything done. This has intensified with other shows on the Hub receiving Emmy nominations instead of FiM.
FiM and Adventure Time is a strange, though glaring, example. There's a number of Pony fans who enjoy Adventure Time, but very few AT fans who like FiM. Among Pony fans who don't like Adventure Time, they see it as nothing but random/trippy shit and Toilet Humor. Meanwhile, Adventure Time fans see FiM as far too girly and life-lesson filled… and aren't happy that MLP stole their thunder as the "it" cartoon online so soon. Bringing up one around fans of the other rarely ends well.
Incidentally, Friendship Is Magic and Adventure Time seem to be the two most cosplayed western animation franchises at conventions. It may or may not have stemmed from this rivalry.
There seems to be a bit of a tense relationship between fans of The Legend of Korra and the bronies. However, none of the episodes coincided with the release of one of the other series, as FiM's season 2 finale happened the week before Korra premiered. Their rivalry is mostly arguing over which show is better, even though most bronies like Korra, and several Korra fans like MLP.
Before Littlest Pet Shop (2012) was released, Bronies were highly wary of the cartoon, seeing it as a cheap rip-off and/or a naked attempt by the Hub to recreate the buzz they got with FiM. The franchises have mostly managed to avert becoming rivals, though they're dancing between – on the one hand, Bronies love to support the writers and actors in all their works (FiM & LPS share an animation studio, music composer, and several voice actors). On the other hand, FiM is the one true way and anyone who says otherwise is a deranged lunatic.
The ongoing nuclear-level war between Bronies and the Furry Fandom. Many people who aren't on either side often lump all bronies in with furries, and since furries are still an Acceptable Target on the Internet, bronies are quick to say that they're not furries. Likewise, some furries hate the fact that ponies are spreading all over the Internet like a Discredited Meme, and take a sort-of-vengeful delight at the (often unintentional) slander that the media is pouring over the bronies, with the justification that "we had to go through this shit, so it's only fair they do too".
There is some crossover between the two camps. Naturally, Brony furries are despised by both factions.
The infamous Cold War of FiM vs. My Little Pony G3 or My Little Pony Tales. Fans of the former see the latter shows as too girly, poorly written, poorly acted, poorly animated, and not by Lauren Faust. Fans of the latter two shows tend to dislike FiM because it's too full of random pop culture references, full of gratuitous slapstick elements (and since the Pony Wedding two parter, some violent elements), and being too dark (especially after Season 1, when Hasbro allowed more educational elements to be left out, costing the show it's E/I certification).
Adding to the rivalry is the general perception of bronies and how some have cyber-bullied fans of Tales and G3 at one online venue or another- it's not unusual to hear reports of bronies sending death threats to fans of Tales and/or G3 via PMs at forums or via e-mail every now and then.
Within the FiM fandom itself there's Adventure Story fans vs. Slice of Life fansnote It should be noted that not all of the slice of life fans who're drawn to the show are new- in fact, a large number of said slice of life fans were drawn to MLP as far back as during the Tales era and stayed on because subsequent era MLP media up until FIM Season 2 (with the exception of the FIM Season 1 premiere two parter, which many of the latter was hoping to be a fluke that'll never recur) were also slice of life.. The former were irritated that so many episodes of the latter appear in the earlier seasons, assuming that Hasbro must have been intentionally holding back Lauren's vision of "Sailor Moon with Ponies" (however, the real reason was that slice-of-life episodes are just easier to make). Fans of the latter are annoyed that, since Lauren's departure during Season 2, the show has been throwing in less slice of life elements and raising the stakes (causing the show to lose its E/I certification in the process).
Complicating the matter is that some fans of My Little Pony And Friends are siding the bronies and also waging war on Tales and G3 fans, as they believed that Hasbro took the wrong turn with Tales and G3, and want the shows of the franchise to return to it's pre-TalesDarker and Edgier roots.
Bronies and fans of Sonic the Hedgehog mix about as well as nitro and glycerin most of the time. In particular, posting an image that ships Rainbow Dash with Sonic will trigger an explosion that can be seen from space. When news broke out that Friendship Is Magic writer Dave Polsky would be on board for Sonic Boom, the war went up to a new level, albeit started mostly by the Sonic fans, who would rather have absolutely nothing to do with anything even tangentially related to Friendship Is Magic in their lives. In fact, some Sonic fans have disowned Sonic Boom for precisely this reason. The hate runs that deep.
The darker, more serious, "down-to-earth" Young Justice with 2D animation and realistic designs have one with the lighter, funnier, space-centered Green Lantern: The Animated Series with 3D animation and Bruce Timm's signature designs. Even when both shows were cancelled and people online were starting to start campaigns to bring them back, more than a few fans were solely focused on bringing back YJ and are more than willing to turn their backs on GLTAS and leave them in the dust, while GLTAS fans tended to be snobby and resentful towards YJ due to higher popularity.
The Beware the Batman fans and Teen Titans Go! fans are not friendly with each other, to say the least. This mostly has to do with the contrasting treatment both shows get from Cartoon Network. Beware the Batmangot little to no advertising and only aired during its one timeslot on DC Nation. Teen Titans Go!, on the other hand, is advertised to the point where "Adored by the Network" doesn't even begin to describe it, and it also gets a primetime slot on Tuesdays as well.
The phenomenon itself is parodied in South Park with Lord of the Rings and Game of Thrones fans looking down on Harry Potter and Star Trek fans.
For a while, there was a bit of a rivalry between fans of Hey Arnold! and Recess, due to fans of the former seeing the latter as a watered-down copy (Despite the fact that the only things the show have in common are that they star fourth graders, many episodes were based around urban myths told by the characters, and they had a similar voice cast). Fortunately, this didn't last very long, and they've become Friendly Fandoms.
Adventures of Sonic the Hedgehog vs. Sonic Sat AM. Back in the 90's, almost everyone loved SatAM but hated AoStHnote (it should be noted that AoStH had a small isolated niche at the time, but fans of both series never clashed due to the infancy of the Internet and how hard it was to get a connection back then- especially since most of the AoStH fans were in Asia). Then in the mid-2000s, with the rise of YouTube Poop, AoStH became Vindicated by History and wars between which one was better broke out. AoStH fans dislike SatAM for its portrayal of Robotnik as a genuine villain, its Darker and Edgier nature, and Sally Acorn, while SatAM fans hate AoStH because it's completely wacky and nonsensical (and also because of its infamously Off Model animation).
And then there's AoStH vs. SatAM vs.Sonic X (almost everyone hates Sonic Underground, so few fights occur over that onenote Except, again, certain parts of Asia, given the frequency of reruns Sonic Underground gets compared to AoStH and SatAM combined on KidsCo in the market. They've even went as far as giving the show a trilingual dub selectable on the IPTV, cable and satellite boxes that receives the channel!). Fans of the former two dislike the latter for its shift of the setting to Earth, Chris Thorndyke, the fact that it uses the Japanese canon (and its Loads and Loads of Characters), and perceived poor voice work. Sonic X fans dislike the two American series for being In Name Only adaptations, episodic plots, Off Model animation (though one can rebut that Sonic X looks a little too slick), and not being Japanese.
Phineas and Ferb vs Gravity Falls. It has been that way since Gravity Falls premiered. Some Phineas and Ferb fans blame and hate Gravity Falls because they feel that it destroyed Phineas and Ferb 's popularity and find it overrated, and a number of Gravity Falls fans detest Phineas and Ferb due to its cliché formula, its art style, bland characters, and for repeating jokes. And they most likely hate the show because it's Adored by the Network and could be the reason why Gravity Falls is on so many hiatuses, despite the same thing often happening with Phineas and Ferb after 2012.
Averted in the UK, as Gravity Falls and Phineas and Ferb fans are actually friendly with each other.
Rugrats vs Sponge Bob Square Pants. This war is the Nickelodeon equivalent to The Simpsons vs Family Guy war. Rugrats fans hate SpongeBob for being nothing more than a vehicle for writers to tell jokes, mean spirited, getting credit for what other shows have done before it & the fact that despite not having a Hollywood Walk of Fame spot & spinoffs, that the latter show has become more successful than the former & SpongeBob fans hate Rugrats for relying on toilet humor & often accuse Rugrats as being played out & appealing to the lowest common denominator by adding new characters to the show. A real highlight that shines a light on this particular fandom rivalry is that fans of either shows are quick to point out that the former or the latter shows have suffered worse in quality.
Actually for a while, there have been fans of The Ren & Stimpy Show and Rocko's Modern Life that clashed with Rugrats fans. Much like SpongeBob with Rugrats itself today, fans of those two shows in particular blamed Rugrats for the reason that those two shows were cancelled, despite Ren & Stimpy being perceived as "going downhill" when John K. left. This was mostly happening when Rugrats was still on, even in the late 90s. However, it has cooled down a lot, but there are a few fans of those two shows that still blame Rugrats for the reason that those two shows ended.
For a while in the late 90s, there was apparently a small Rugrats Vs. CatDog war going on. Given that Rugrats was still around (albeit in a badly decayed state as it's spinoff, All Grown Up!, and counting it's days) by the time CatDog disappeared, it is assumed that the Rugrats fans apparently won a Pyrrhic Victory.
Grojband vs. Uncle Grandpa. Fans of Grojband are prone to blame Uncle Grandpa for hogging their airtime, causing the lack of reruns of Grojband, and causing the Series Hiatus to get even worse, and what's even worse is that Uncle Grandpa was already Adored by the Network before it even premiered.
