* ''WesternAnimation/AdventureTime'':
** There was a quick little shipping war between fans of which girl they thought was better for Finn. [[EnsembleDarkhorse Marceline the Vampire Queen]] or Princess Bubblegum. The war was ended when Marceline/Finn [[ShipSinking was sunk]] by Marceline herself and "Mortal Recoil" has given Bubblegum an age regression, turning her 13, and making her a compatible ToyShip with Finn. Finn dates Princess Bubblegum in her age-regressed state but it doesn't last. In the episode "Too Young," PB returns to her proper age to evict a "friendly" usurper.
** In the episode "What Was Missing," Bubbline (Marceline/Bubblegum) took off big time. The episode itself seems loaded by the writers with slashy tinder. The tension between Marceline/Bubblegum, Finn/Bubblegum, and Finn/Marceline fans was noticeable, even before Flame Princess came onto the scene.
** Finn had a new love interest in the Flame Princess. Shippers quickly got into combat mode, with both Finn/Bubblegum and Finn/Marceline shippers [[DieForOurShip screaming at her]] while Bubblegum/Marceline fans [[ShipMates teaming up]] with Finn/Flame Princess shippers so they could have their cake and eat it whole. Finn/Flame Princess was sunk eventually, seeing as how Finn manipulated her into fighting Ice King. She says they can still be friends though. This, however, is no good for those who still ship them. At this point, fans accept one of two outcomes: either Finn and Flame Princess get back together, or Flame Princess is KilledOffForReal.
** In the series finale, [[spoiler: Marceline and Bubblegum get together while Finn remains romantically unattached, although previous seasons showed him develop a [[UnresolvedSexualTension mutual but unresolved attraction]] towards Huntress Wizard.]]
* The ''WesternAnimation/AllGrownUp'' fandom was prone to this and the show's main forum was rife with it. Essentially, it was Tommy/Kimi vs. everyone else, as Tommy/Kimi broke up two of the show's other popular ships (Tommy/Lil and Phil/Kimi). Chuckie/Angelica shippers tended to be more prone toward the Tommy/Lil-Phil/Kimi side of the fence, just to stir the pot further. An attempt at a fan-written continuation of the series collapsed into a several-page argument between Tommy/Kimi, Phil/Kimi and no shipping at all. This was largely due to long-standing rivalry between the writers involved, but the passion of the whole thing was indeed kind of frightening.
* ''WesternAnimation/{{Amphibia}}'' has an InUniverse example in the episode “Civil Wart.” After the residents of Wartwood watch a ''Film/{{Twilight}}''-esque film on Anne’s phone, they [[SillyReasonForWar wage war]] over it.
* ''WesternAnimation/AvatarTheLastAirbender'' serves as the page image for this trope, so naturally there are quite a few examples:
** Depending on the board, the fandom is either surprisingly civil or at least as bad as any other. The main fight is between what would become the OfficialCouple of Kataang (Katara/Aang) and the FanPreferredPairing of Zutara (Zuko/Katara). Watch out for ShipMates. Overall, the series makes a very good example of the dynamics of most ship-to-ship warfare: Katara/Aang is an example of shipping characters who share almost all of their interests in common and get along with small, day-to-day issues (which arguably makes for the more straightforward and sensible relationship). In contrast, Zuko/Katara is an example of shipping characters with complementary personalities (i.e., more entertaining to watch interact onscreen) who share similar emotional baggage (both lost their mothers due to the Fire Nation's actions). Thereby turning the whole thing into a grand debate on how relationships work and what the purpose of fictional relationships is. None of this is helped by the creators regularly poking fun at the latter pairing, calling it a nonsensical one that could never possibly work long-term... which only made Zutarians ship it ''harder''.
*** This somehow continued into ''WesternAnimation/TheLegendOfKorra'', where we learned with the show's announcement that Aang and Katara stayed together into adulthood and had at least one child (it turns out they had three). Some Zutarians stuck to the pairing, insisting that Katara ''had'' to have gone to Zuko for comfort after Aang's death [[GoodAdulteryBadAdultery (if not well before)]]. The latter had some Zutarians heralding the "revival" of Zutara, or claiming Zutara to be an AnchoredShip.
** There was also the whole debate concerning Zuko's ships, Mai/Zuko and Katara/Zuko. For the former, the two have similar, cynical personalities, share the same hardline approach to life, and the two tended to be at their happiest with one another, yet they share little if any interests or goals, have little to no chemistry[[note]] as in, if they aren’t cooing over one another, they treat each other as coldly as they would anyone else[[/note]], and they are reluctant/outright refuse to open up to one another, leading to numerous bitter break ups. For the latter, the two tend to be on opposite sides of an issue and have contrasting methods in approaching said issue[[note]]most importantly, how to deal with Aang[[/note]], but while they come into conflict often, they are also capable of quickly and easily reaching an understanding, they share similar hang ups and bond over them, and have excellent chemistry. The battle seems to have died down a bit, but there are still many fanatics who subject Katara or Mai to DieForOurShip.
*** Both the comics and ''Legend of Korra'' complicate matters. ''Korra'' confirms that Zuko has at least one daughter and one grandson, but never states who his wife was. If you weren't aware of the comics, you'd assume it was Mai. But she and Zuko break up in [[ComicBook/AvatarTheLastAirbenderThePromise The Promise]], followed by both it and ''The Search'' teasing at [[BodyguardCrush Zuko/Suki]]... but then ''Smoke and Shadows'' hinted that Maiko could make a return at some point. Sokka/Suki fans have grabbed their war paint, my friends.
** There is also Sokka/Suki vs. Sokka/Toph, which intensified when ''The Legend of Korra'' didn't even mention Suki once, making it unclear whether or not she and Sokka stayed together. Many Tokka shippers initially speculated that Sokka may have fathered Toph's daughter, Lin, but it was later revealed she [[KissingCousins dated his nephew]]. When it turned out Toph had a second daughter, Suyin, with a different father, the theory was back on the table. However, some fans objected to the idea Sokka was an [[DisappearedDad absent father]], as Suyin's backstory implies.
** [[http://sora-ko.deviantart.com/art/Avatar-The-true-showdown-41464296 This comic]] takes it to its literal extreme -- or perhaps [[{{Pun}} its littoral extreme]]. (And [[http://rufftoon.deviantart.com/art/Shipping-Wars-1-43734136 this one]] does the same, but speaks more for those who tend not to ship).
* Where to start with the convoluted ''WesternAnimation/{{Ben 10}}'' fandom? Said fandom has three major ships, [[RomanticPlotTumor Gwen/Kevin]], [[KissingCousins Ben/Gwen]], and [[HoYay Ben/Kevin]]. During the air of the original series, the Ben/Gwen and Ben/Kevin shippers were the most common (Gwen/Kevin was still a CrackPairing)...
** ...but during ''WesternAnimation/Ben10AlienForce'', all hell broke loose when Gwen/Kevin became canon. Ben/Gwen shippers still protest about [[DieForOurShip how much discontinuity problems this causes for the series]], while Gwen/Kevin shippers bask in the light of their newly canon ship and Ben/Kevin shippers stay well out of the way, enjoying the {{subtext}} the [[PlatonicWritingRomanticReading writers seem to be handing out]].
** There seems to be attempted ShipSinking in Season 2, what with the added emphasis on Ben's Canon girlfriend Julie. The primary effect of this has been to make Ben/Gwen shippers and Ben/Kevin shippers [[EnemyMine ally against their common foe]].
** And then came ''Omniverse'', which gave us Ben/Rook, [[FirstGirlWins Ben/Kai]], and Ben/Esther, among too many others to list. Eventually, many of these shippers pulled an EnemyMine against Ben/Kai, due to [[StrangledByTheRedString how the pairing was handled when it finally became canon.]]
* The ''WesternAnimation/ChipNDaleRescueRangers'' Ship-To-Ship Combat is actually about only one pairing, namely Chip/Gadget. Those who favor that pairing oppose those who do not want to see Chip and Gadget together, regardless of alternatives. This led to two flame wars on the Usenet in 1997 and at the fan forum [[http://www.theacorncafe.org Acorn Cafe]] in 1998. Further flame wars could only be prevented by the experience gained during 1998's St. Valentine's Day Massacre and by "agreeing to disagree". A third, rather small faction among them call themselves the Neutrals and dislike the wary ways of both Pro and Anti fundamentalists. Mind you that there has never been a canonical pairing in this show.
* WesternAnimation/ClassicDisneyShorts characters usually avoid this due to how concrete the {{Official Couple}}s are. WesternAnimation/{{Goofy}} is the exception. Goofy has never had one exact love interest like WesternAnimation/{{Mickey|Mouse}} or WesternAnimation/{{Donald|Duck}}. In the 2000s Disney revived Clarabelle and began shipping her with Goofy. The problem is that Clarabelle traditionally ''has'' a boyfriend--Horace. A lot of Goofy/Clarabelle versus Horace/Clarabelle tension exists. Then there's Goofy's girlfriend in the ''WesternAnimation/GoofTroop'' universe, Sylvia from ''WesternAnimation/AnExtremelyGoofyMovie''. She never became a CanonImmigrant like Max, however she occasionally gets drawn in.
* The ''WesternAnimation/CodeLyoko'' fandom features a large group of people who ship Aelita and Odd and are combated vigorously by the people who support Aelita and Jeremie, the show's OfficialCouple. But of course this is nothing when it comes to the Ulrich/Yumi/William/Sissi debates.
* ''WesternAnimation/CodenameKidsNextDoor'': Say one shipping, and you'll have shippers SWARMING YOU WITH FURY. While most fans ship 4/3, there is a never ending conflict between shippers of 1/5, 2/5, 1/362, 86/362 and 2/86 that continues 20 years after the show started airing. You may want to wear [[FunWithAcronyms battle ready armor]] for this.
* ''WesternAnimation/TheCupheadShow'': There's some conflict between people who ship Cala Maria with Mugman and those who ship her with Brineybeard. In the original game, Briney and Cala never interacted with each other (though they were both sea-themed antagonists who sold their souls to the Devil), and the interaction between Mugman and Cala Maria were purely antagonistic. In the show, Brineybeard is madly in love with Cala Maria, who first just wants to eat him but she gradually starts to like him, whereas Mugman is frightened of her first but eventually develops a PrecociousCrush on her (so much that in a later episode, when he reads a romance book, he imagines the protagonist as himself and the love interest as Cala Maria). People who oppose the Mugman/Cala Maria ship point out that he is a child whereas she is an adult.
* The shipping wars within the ''WesternAnimation/DannyPhantom'' fandom became (in)famously known as the "True-Fan vs. Anti-Fan" wars, and ran rampant throughout sites like Website/DeviantArt. The wars involved the canon pairing of (Danny/Sam) vs. the popular fanon pairing ([[DatingCatwoman Danny/Valerie]]), but also had a huge focus on heterosexual parings (Danny/Sam, Danny/Valerie) vs. homosexual/slash pairings ([[FoeYayShipping Danny/Vlad]], Danny/Dash, and even Danny Fenton/Danny Phantom).
** How bad was it, you ask? Well, anyone who supported "Fanon" pairings were considered an "Anti-Fan" whom the "True-Fans" disregarded as propagating "filth and pornography" (even if artwork/fanfic of said pairing was completely "G" rated). Likewise, the supporters of "Canon" pairings were called "[[GodwinsLaw Canon Nazis]]" whom the "Anti-Fans" would often accuse of "not understanding artistic freedom". Not to mention that simply being friends or liking the artwork of someone on one side of the battlefield automatically made you enemies with the other. Thankfully, these days, the war seems to have died down a bit.
** One fan going by the name of Wolf O'Donnell stepped forward and created the iconic ship to end all ships in protest of all of this: Cream Soup. Otherwise known as [[CargoShip Danny/the Fenton Thermos]]. The Cream Soup ship was for those who simply don't want to get so involved in shipping. Fanons are slowly starting to use this one.
%% * Oh, be thankful that the shipping wars of ''WesternAnimation/{{Daria}}'' are over! There are ''STILL'' Daria/Trent shippers out there -- the biggest contingent, who were set to declare holy war when the WordOfGod ''{{Jossed}}'' that pairing in the third season finale by showing that reality would never support the pairing. Still, that's '''NOTHING''' compared to what happened a season later. Want to start a war in Daria fandom? Two words: ''"The Kiss."'' Daria/Tom shipping has caused heated arguments the way the Sun provides heat and light for the Earth. And the real irony is that in the end of the show, they ''broke up'' and Daria stayed single, so ''neither'' pairing is is OneTruePairing. This isn't even mentioning those who still cling desperately to [[LesYay Daria/Jane]] versus those who dislike it.
* ''WesternAnimation/EdEddNEddy'':
** There was always a bit of animosity between Edd/Eddy and Edd/Kevin fans however it was downplayed due to the former being significantly more popular... Until [[Webcomic/AUReverse a popular artist]] on Website/{{Tumblr}} caused Kevedd to ''explode'' in the early 2010s. This caused a resurgence in the fandom, however these newer fandom members tend towards Kevin/Edd. Naturally the Edd/Eddy fans (many of which who have been in the fandom since the early-to-late 2000s) started getting mad and the ship wars were revived. Edd/Ed, Edd/Marie, Edd/May, and Edd/Nazz rarely get brought into the mess.
** When it comes to shipping Edd with girls, there's a lot of ship warring. The three most popular are Edd/May, Edd/Marie, and Edd/Nazz however the fans rarely get along.
* ''WesternAnimation/TheFairlyOddparents'' has its own, with the main combatants seeming to be Timmy/Tootie (Tootie is obsessed with Timmy but he doesn't like her back), Timmy/Trixie (Timmy likes Trixie but she [[ShipTease usually]] brushes him aside), and Timmy/Chloe (Chloe being Timmy's new neighbor introduced in the last season). However, Veronica/Timmy also has its own devoted fanbase (even though Veronica was only shown to like Timmy in two episodes and she expressed it in a very... interesting way). There is also a minority of Timmy/Vicky shippers, who enjoy the FoeRomanceSubtext between them or want Vicky redeemed.
* ''WesternAnimation/{{Gargoyles}}'':
** The ''Gargoyles'' fandom has had this going on for over a decade after Goliath's daughter Angela hooked up with Broadway over Brooklyn (and [[IWantMyBelovedToBeHappy Brooklyn himself was very graceful about his "loss"]]). While most fans understood that Broadway was the correct choice, even if not the obvious choice, there are still fans who believe she should have hooked up with Brooklyn, and it intensified after Greg Weisman came out and said that Brooklyn's attraction to her was shallow and superficial. The arrival of Brooklyn's true love, Katana, seems to have finally laid this to rest... however there are still some hold-outs because "Katana is not hot." ([[http://gargwiki.net/Katana This is what Katana looks like]], by the way.)
** For a period, several years back, there were militant shippers who believed that Demona and Elisa Maza should be a couple. While some were doing it just for the fun, there was a rising faction who were dead serious about it. They even denounced Greg Weisman as a writer, and attacked him for not writing "realistic relationships." So, according to these people, Demona and Elisa were meant for each other. One is a human, and one wants to commit mass genocide upon humanity, and each despises the other.
* ''WesternAnimation/TheGhostAndMollyMcGee'':
** As early as the first episode, a rivalry started between Molly/Andrea fans and Molly/Libby fans. Much of the Molldrea fanbase started from FoeYayShipping and got even stronger as the character began having positive interactions to the point of becoming friends by Season 2, while Mollibby rode on a 'friends-to-lovers' scenario from the very start.
** Season 2 threw in the Molly/Ollie ship, which immediately began receiving flak from Molly/Libby and Molly/Andrea shippers. In return, the Molly/Ollie shippers accuse the other two shipping factions of putting their ShippingGoggles on too tightly, and disrespecting the creators' choice of pairing Molly with Ollie instead of Libby or Andrea.
* ''WesternAnimation/GravityFalls'':
** Just like the ''WesternAnimation/InvaderZim'' fanbase, the biggest shipping war is between those who ship Pinecest (Dipper/Mabel) and those who despise it. The fact that the creator based the two main characters off of him and his sister doesn't help the Pinecest shippers at all.
** Season 2 caused quite a large war between Wendip (Wendy/Dipper) shippers and the newly-growing Dipcifica (Dipper/Pacifica) shippers. While for Wendip, there was early [[spoiler:ShipSinking, the ship has been reinvigorated towards the end thanks to hints surrounding the final six episodes,]] Dipcifica only really has one episode of ShipTease, and it is one of the only other ships likely to happen besides Wendip, unless Dipper meets a new girl, though the fans will never know. Further complicating things is that while Dipcifica was only briefly teased in the series, the [[AllInTheManual tie-in materials]] like ''VideoGame/GravityFallsLegendOfTheGnomeGemulets'', ''Literature/GravityFallsJournal3'', and ''ComicBook/GravityFallsLostLegends'' seem to lean more towards Dipcifica.
** Season 2 also caused a completely different ship war between those who like Dipcifica and those who like Mabifica (Mabel/Pacifica).
** Eventually, as time went on after the show ended, most of the ship wars died down, although Dipcifica shippers often remain at odds with the majority of other shippers.
* Strangely, the ''WebAnimation/HappyTreeFriends'' fandom engages in this. The wars often revolve around who Flaky will end up with. Never mind that Flaky is a character who is never romantically involved ''and'' her [[ViewerGenderConfusion gender]] is still [[SeriousBusiness quite the subject of debate]]. And then, there's [[FanPreferredCouple Flippy/Flaky]] vs. [[HoYay Flippy/Splendid]], as well. Flippy/Flaky vs. a part of the fandom that can't stand the couple pops up frequently because of how common in {{fanon}} the pairing is.
* ''WesternAnimation/HarleyQuinn2019'': Harley/Ivy vs Ivy/Kite-Man. Possibly the biggest draw of the series has been the possibility of Harley Quinn and Poison Ivy forming a romantic relationship like their comic book counterparts. When Ivy started seeing Kite-Man, it was seen as just a running gag. But then they got serious, and now the show is divided into two camps: those who see Ivy/Kite-Man as surprisingly well-written and sweet and deserving to be explored, and those who think the show has used good old-fashioned queerbaiting to entice LGBT viewers with no payoff. As the series is ongoing, time will tell how things play out. One factor that leaves Harley/Ivy fans hopeful is that the ladies (at least in the comics) are no strangers to polyamory.
* The ''WesternAnimation/InvaderZim'' fandom has little fighting, probably because the show only focuses on a few main characters and Dib/Gaz is unpopular for [[BrotherSisterIncest obvious reasons]]. The biggest ship war is actually just between those who like [[FoeYayShipping ZADR]] and those who despise it, especially since Creator/JhonenVasquez [[WordOfGod says]] it makes him "sick to his ill-prone belly." Building on that, there is a small collection of anti-shippers who are [[NoHuggingNoKissing against pairings]] in general, but ZADR is where they direct most of their ire. There is also actually a pretty big fight between [[FoeYayShipping Zim/Dib]] shippers and [[SlapSlapKiss Zim/Gaz]] shippers. And let's not forget [[FoeYayShipping Zim/Tak]] and Dib/Tak. Or [[LesYay Gaz/Tak]].
* ''WesternAnimation/{{Jem}}'':
** Kimber has Kimber/Sean versus Kimber/Stormer, Kimber's main boyfriend against Kimber's PseudoRomanticFriendship. Jeff rarely gets brought into the debate.
** This is encouraged in season 3: Is Jem best with Rio or Riot? Jem shows interest in both and the series ends on NoRomanticResolution. That's not even getting the mildly popular Jem/Pizzazz ship involved.
* ''WesternAnimation/JusticeLeagueAction'' is one of the few adaptations to use Franchise/{{Superman}}[=/=]Franchise/WonderWoman. Naturally, this caused a storm within the fanbase, with Lois/Superman fans and Steve[=/=]WW fans getting into arguments with fans of this pairing about which couple is best. Franchise/{{Batman}}[=/=][=WW=] fans also entered the mix, thanks to the previous Justice League show having popularized that pairing.
* While not as extreme as some of the others mentioned on this page, there's the ComicBook/GreenLantern[=/=]Hawkgirl shippers vs. the Green Lantern/Vixen shippers for ''WesternAnimation/JusticeLeagueUnlimited'', even though both are canon, and there was a big reveal about [[spoiler:Warhawk being Green Lantern and Hawkgirl's son in the future]], and WordOfGod has pretty much said the Green Lantern/Hawkgirl shippers have reason to be victorious in this fight. And yet there's still friction between them.
* While most ''WesternAnimation/{{Kaeloo}}'' fans ship Kaeloo and Mr. Cat, a few of them ship Mr. Cat with Pretty. On occasions, things can get ugly when the fans start fighting over which ship is better.
* The ''WesternAnimation/KimPossible'' fans of the [[{{Canon}} Kim/Ron]] pairing will viciously attack any fans of [[HoYay Kim/Shego]] like a piranha-feeding frenzy. Any sign of Kigo FanArt will invariably get several negative comments from a Kim/Ron supporter; the same can be said of any {{Fan Fic}}tion. And of course, Kigo shippers will invariably call the Kim/Ron pairing "mainstream" or "not gritty enough" or accuse the Kim/Ron shippers of homophobia. There was a major fight that occurred between the [[DieForOurShip Kigo and K/R shippers]] a while back. Nowadays, the topic is kept out of most forums for obvious reasons. Most enjoy both shipping sides nowadays and there are some that even enjoy mixing the ships.
* ''WesternAnimation/TheLegendOfKorra'':
** Even before Book 1, there was already a huge brewing shipping war between Korra/Mako fans and Asami/Mako fans. It didn't help that many Zutara shippers [[{{Pun}} Jumped Ship]] to Makorra after Zutara was definitively [[ShipSinking Sunk]]. There also was a war brewing between Korra/Mako fans and Korra/Bolin fans as well, including arguments on which brother [[UnfortunateImplications "deserves Korra more"]] and vice versa. Asami and Mako became a couple early on, though with continuous {{ship tease}} between Mako and Korra. Despite Episode 5 [[ShipSinking sinking]] [[PortmanteauCoupleName Borra]], it grew massively in popularity to due to the chemistry between the two, turning the shipping wars into a duel between Borra and Makorra. Mako's poor treatment of Asami caused most to [[AbandonShipping jump ship]] and turned Makorra's OfficialCouple status divisive, which was not helped by the ambiguous breakup between Mako and Asami to assume that Mako was cheating on both of them. [[LesYay Korrasami]] grew as a [[CrackPairing fringe ship]] that mostly started as a protest against the LoveTriangle that everyone was quickly becoming frustrated with. Remember that for later.
** Book 2 saw the growth of [[PairTheSpares Asami/Bolin]] partly as a reaction to how the shipping war had hurt both Korra and Mako's popularity within the fandom, and it quickly clashed with the canon [[{{Yandere}} Eska]]/Bolin. Mako and Korra eventually [[ShipSinking broke up]] for good, with Mako's botched handling of an amnesiac Korra after getting back together with Asami midway through the season obliterating Mako/Asami and only [[RonTheDeathEater worsened]] [[NeverLiveItDown his]] status as TheScrappy.
** Die-hard Makorra shippers continued to hope that their ship would get back together in Book 3, though it never happened. This season also saw the meteoric rise of Korrasami to OneTruePairing as the series explored their friendship (once again, remember that for later). Hopes for any other ships involving Bolin collapsed with the introduction of [[TheCutie Opal]] as his new love interest, who proved to be fairly popular.
** [[BrickJoke Now it's later]]. Book 4's shipping wars consisted of Makorra and Korrasami fighting it out, though many expected Korra to canonically end up alone. After the finale suggested that all the HomoEroticSubtext may not have been ShippingGoggles but fully intentional, heated debates over what the final shot meant erupted, with Makorra shippers leading the "Just Friends" charge. Then WordOfGod confirmed that [[http://bryankonietzko.tumblr.com/post/105916338157/korrasami-is-canon-you-can-celebrate-it-embrace Korra and Asami are indeed bisexual and Korrasami is canon]], causing major opposition to cease, with only some angry holdouts.
*** After the fandom settled down post-finale, interactions between the Makorra and Korrasami camps have been largely respectful, or at least civil due to the former group continuing to shrink with each passing day. While there's still debate, both sides are much more inclined to agree to disagree, never quite reaching the emotional fervor of the Kataang-Zutara days. That is, until the concept of homo/biphobia comes up. Then a whole different sort of argument starts, [[PoliticalOvercorrectness and]] [[HeteronormativeCrusader it]] [[NoBisexuals isn't]] [[MoralGuardians pretty]].
*** Increasingly Averted as time passes from the finale and the canon [[ComicBook/TheLegendofKorraTurfWars spin-]] [[ComicBook/TheLegendofKorraRuinsoftheEmpire offs]] focus on [[spoiler:[[OfficialCouple Korrasami]].]] Makorra's popularity is declining, while Korrasami remains popular as ever. Within the metaphor, the war could be said to be over.
** Ever since the revelation that Lin and Tenzin once were in a ChildhoodFriendRomance, the Tenzin/Lin shippers have pushed for their ship, often bashing the shit out of Tenzin's actual wife Pema in the process, labeling her as [[RonTheDeathEater a slutty home-wrecker]] without any evidence. Naturally, the Tenzin/Pema fans have retaliated...
* Kion/Jasiri and Kion/Fuli are two of the most popular {{Toy Ship}}s in ''WesternAnimation/TheLionGuard''. Ship wars have popped up as a result, despite the [[NoHuggingNoKissing lack of actual romance]] in the series. At least until the final season, when the canon Kion/Rani ship joined the mix.
* ''WesternAnimation/TheLoudHouse'':
** {{L|auncherOfAThousandShips}}incoln has been hinted to have a crush on various girls throughout the series, including Christina, Girl Jordan, and Stella. However, the most popular of these is Ronnie Anne, a Hispanic girl who was a former bully of his, but gradually developed feelings for Lincoln in the show's early episodes. Despite being one of the most popular ships in the fanbase, various detractors are quick to point out that Ronnie Anne's treatment of Lincoln is borderline abusive and that she started off viciously bullying him. Some have alo made note of how Lincoln and Ronnie Anne have shown very little (if any) romantic interest in one another since the latter moved to Great Lakes City in the show's second season, and are now just seen as friends. The fact that Creator/{{Nickelodeon}} [[https://www.instagram.com/p/BNxHfShhPoc/ officially debunked]] Ronniecoln hasn't helped to settle these shipping wars, with Ronniecoln supporters arguing Lincoln and Ronnie Anne's denial of being significant others as behavior typical of kids their age. In the series' live-action adaptation, ''Series/{{The Really Loud House}}'', Lincoln developed a crush on a girl named Charlie, with Ronnie Anne completely absent from the series. Ronniecoln supporters were angered by this change, considering it unrelated to the original series' canon.
** Even though Benny and Luan were promoted to OfficialCouple, that hasn't changed the minds of an extremely vocal group of fans who ship Luan [[{{Yuri}} with Maggie]]. Pointing out that [[ShipsThatPassInTheNight they never said one word to each other]] in the one episode Maggie has actually appeared in won't help your case, either.
* ''WesternAnimation/MiraculousLadybug'' shipping is interesting because the four main ships are between two characters who act so differently between their civilian and superhero identities that they count as four separate ships. There's "Adrienette", the pairing between Marinette/Adrien, their civilian identities; "Ladynoir", the pairing between Ladybug/Chat Noir, their superheroes identities; "Marichat" the pairing between Marinette/Chat Noir; and "Ladrien", the pairing between Adrien/Ladybug. This is just as confusing as it sounds, and also ignores the show's own arc concerning the characters learning to stop separating their personas as much as they do in order to become more well-rounded people.
** Season 2 added Luka and Kagami to the mix as possible love interests for Marinette and Adrien, respectively. While the resultant "Lukanette" and "Adrigami" factions tend to unite against the wrath of the Love Square shippers, they're also prone to their own fights because of how said factions (partly) formed: some Lukanette shippers got fed up with Adrien's EntitledToHaveYou behavior towards Ladybug and doormat tendencies and decided Marinette would be better off without him, while some Adrigami shippers got fed up with Marinette's [[StalkingIsFunnyIfItIsFemaleAfterMale stalking tendencies]] and actions towards her romantic rivals and thought Adrien would be better off without ''her''. Hence, their differing opinions on the show's two leads cause them to argue independent of their preferred ships. And that's ''without'' factoring in the also-competing "Lukadrien", "Kagaminette", and "Lukagami" factions (the first two tend to be allied with each other, and the second one with the various Love Square factions).
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** There are ships that pair Rainbow Dash with Applejack, but there are others that pair her with Pinkie Pie. Fans of one ship will immediately (upon realization) state they don't like the ''shipping'', while stating however, that the story is [X] ([X] being their humble, critical opinion on the author's writing) and so living on to their promise of "loving and tolerating the $c#i+ out of you".
** While fans generally promote "love and tolerance", many still start ship wars, [=PinkieDashers=] in particular.
** If you pair Lyra or Bon Bon with anypony other than each other, you can expect to at least a few times be called a troll, a homophobe, an idiot, or all three. Many [=LyraBon=] fans are perfectly normal, but a lot of them are so possessive of both characters that if you don't accept the shipping of them as "almost canon," and confirmed canon as of the series finale, you'll soon meet a lot of people who neither love nor tolerate your opinion.
** Some plot points to the {{Valentines Day episode|s}}, [[YouMeanXMas Hearts and Hooves Day]], were revealed early. It was revealed that the [[DesperatelyLookingForAPurposeInLife Cutie Mark Crusaders]] try to hook up [[GentleGiant Big Macintosh]] and [[SchoolMarm Cheerilee]]. Big Mac and [[ShrinkingViolet Fluttershy]] is one of the most popular ships in bronydom, so naturally, the [=FlutterMac=] shippers [[DieForOurShip took exception]] - before the episode had even '''aired''' and before it was established that [[StatusQuoIsGod anything had changed in the first place]]. And a lot of people found the episode a SugarWiki/{{Funny Moment|s}} because in a way it said "shipping is bad" since the plot was about making two people fall in love because you think they'll work. Cue a bunch of teasing fanart all around.
** There can also be quite a bit of friction between [=FlutterMac=] (Fluttershy/Big Mac) and [=TwiMac=] (Twilight/Big Mac) fans (though it doesn't usually reach the fevered level of some of the other ship wars). And now there's Mac being shipped with Pinkie's sister Marble. Who's a lot like Fluttershy. [[SarcasmMode Fantastic]].
** Then in season 7, he got a canon ship, with Sugar Belle, which just made things worse.
** Let's face it, you really can't bring up a pairing without people complaining about it. Notable examples include shipping {{Original Character}}s with canon characters, merely mentioning Trixie in a non-Twilight/Trixie story (because Twixie has quite a few vocal fans), the very implication of Bic Mac being with anypony that isn't Fluttershy or Cheerilee, any of the Background Six getting together with anypony other than their double (Derpy and the Doctor, Lyra and Bon Bon, and Vinyl Scratch and Octavia), and most anything involving Princess Celestia.
** A three-way conflict seems to be underway. All three factions are fighting over whom Rainbow Dash should be shipped with. [=AppleDash=] is the most popular and generally most organized faction; [=FlutterDash=] (Fluttershy X Rainbow Dash) seems to have the most zealous and passionate fans; and [=TwiDash=] (Twilight x Rainbow Dash), based on the sheer popularity on [=FimFiction.net=], is gaining momentum the fastest out of the three and is recruiting more and more casual first time shippers.
*** Recently, discoveries have been made that a lot of hardcore shippers of various mane six ships will express notable distaste for other main characters. Incidentally, these characters happen to make up halves of other very popular ships. Examples include [=AppleDash=] shippers, who generally hate [=RariJack=] and don't take kindly to Rarity, and [=TwiDash=] shippers, who often loathe [=AppleDash=] and are quick to dismiss Applejack as a background character, boring, a mudpony, or all the above.
** The fandom also is split on whether the Mane 6 are HeterosexualLifePartners or possible lovers.
** There is also an escalating debate based on who the Wonderbolt Soarin should be paired with. Soarindash (Soarin X Rainbow Dash) has one of the largest followings amongst the shipping fandom (not to mention an exceptionally high Website/DeviantArt membership), but faces some competition from Soarinjack (Soarin X Applejack) shippers and Soarinfire (Soarin X Spitfire) shippers as well.
** Any shipping involving [[MadGod Discord]] is subject to controversy. However, following a brief scene in the 4th season's finale in which Discord gives Princess Celestia a bouquet of flowers, a rather heated conflict has emerged between those who ship the two together, and those who ship him with Fluttershy. And that's not even accounting for the debate between [[PortmanteauCoupleName "Dislestians"]], and fans that believe that the [[StarCrossedLovers relationship between]] Celestia and [[ComicBook/MyLittlePonyFriendshipIsMagicIDW The King Sombra of the parallel universe]] should be taken as canon.
** The series finale caused warring between Applejack/Rainbow Dash and Applejack/Rarity fans. The ending implies that [[spoiler:Applejack and Rainbow Dash live together 15+ years in the future]], while ''Equestria Girls'' has ShipTease between Applejack and Rarity (with a WordOfGay to back it up). Fans thought the two worlds were more-or-less parallel, which caused debating on whether [[spoiler:Applejack and Rainbow Dash are a couple or not]].
* Largely averted by ''WesternAnimation/TheOwlHouse''; While two ships involving the main character, Luz, namely Lumity (Luz x Amity), and Lunter (Luz x Hunter) exist and have their fans, the former is overwhelmingly more popular, to the point where it makes up more than 60% of all Owl House fanfiction on [[Website/ArchiveOfOurOwn AO3]], more than any competing or unrelated pairs combined. After [[spoiler:Lumity]] ascended to OfficialCouple status, the fandom largely moved on to other conflicts.
* ''WesternAnimation/PhineasAndFerb'':
** The biggest question is with whom Isabella should end up with. Fans usually ship her with the two principal brothers. That's because she's the only one female character of their age with an important role. A joke in "Quantum Boogaloo" {{Ship Tease}}d Ferb/Isabella (Ferbella), but this pair was never developed in the series. Isabella has a crush on [[ObliviousToLove Phineas]]. Because of this, Phineas/Isabella (Phinabella) simply has much more canon evidence and a significantly larger fanbase.
** That's also a rather controversial question of who Ferb should wind up with. Canonically, he has a PrecociousCrush on [[MadScientistsBeautifulDaughter Vanessa]], who at sixteen is about [[VagueAge two-to-six]] years older than him. Many fans, however, decided to pair him with Gretchen, who originally seems to be chosen simply because she was the first girl his age (other than Isabella) to [[NominalImportance have a name]]; [[ShipsThatPassInTheNight they have never interacted]], though, despite how many times the [[ScoutOut Fireside Girls]] have helped in Phineas and Ferb's projects. And of course, some fans TakeAThirdOption and just invent an OriginalCharacter, pair Ferb with somebody else in the show, or [[OneTrueThreesome have a threesome]].
** Another possible war that could break out is between the [[NotBloodSiblings Phineas/Ferb]] shippers and...well, like the ''Invader Zim'' example above, just the people who ''hate'' that pairing.
** An episode revealed that Johnny, who fans had generally written off as a [[GirlOfTheWeek Boy Of The Week]], [[OfficialCouple was now Vanessa's boyfriend.]] It was not long before Johnny got subjected to [[DieForOurShip the madness of the rabid Ferbnessa shippers.]] Later Vannesa broke up with Johnny...but got a thing for Monty Monogram. here we go...
** This was mostly averted between [[OfficialCouple Jeremy/Candace]] and [[LesYay Candace/Stacy]] shippers. Most of the latter also support the former and there isn't any reported sighting on any debate between the two thus far.
* ''Franchise/ScoobyDoo'':
** Shaggy/Crystal vs Shaggy/Velma. Crystal is Shaggy's love interest in ''WesternAnimation/ScoobyDooAndTheAlienInvaders'', while Shaggy/Velma was a FanPreferredCouple long before ''WesternAnimation/ScoobyDooMysteryIncorporated'' decided to canonize it.
** Fred/Daphne vs Velma/Daphne has caught on in the 2010s. In fact, many fans turned to Velma/Daphne precisely because they were bored of shipping Fred/Daphne.
* ''WesternAnimation/SouthPark'' has a lot of this:
** Shipping wars have gotten especially common since ''You're Getting Old'' aired, where Kyle didn't want to be Stan's friend anymore, and was seen playing with Cartman and smiling at him at the end of the episode, implying that the hostility between Cartman and Kyle is slowly replaced with a building friendship. The rabid [[HeterosexualLifePartners Stan/Kyle]] and [[FoeYayShipping Cartman/Kyle]] fans went crazy, especially since there was a war between the ships even before the episode. Although their friendship ended the following episode, tensions remained high.
** Then there are smaller battles in the fandom, between Cartman/Butters fans and Kenny/Butters fans, Cartman/Wendy vs. Stan/Wendy, and Craig/Tweek vs. Craig/Thomas vs. Craig/Clyde vs Kevin/Clyde.
** As of season sixteen, especially on sites like Tumblr, Stan/Kyle fangirls have begun whittling down or switching in favor of Cartman/Kyle.
** Yet, this only escalated the fighting even more, and fans of other pairings like K2 and Candy have also jumped on the bandwagon of standing their ground against the growing number of Kyman fans. Season 17's run continued the fight between Stan/Kyle fans and Cartman/Kyle fans, with some proponents of the latter hoping it would be officially canonized. Come "Ginger Cow", where the entire episode involved Kyle being humiliated by Cartman and made to "eat farts". This was either seen as deconstructing and shining a light on how unhealthy Kyle would be with Cartman- or alternatively, used by specific Kyman fans as FURTHER proof and fodder for the pairing, with them trashing Stan/Kyle in the process.
* ''WesternAnimation/SpongeBobSquarePants'': [[PortmanteauCoupleName Spandy]] ([=SpongeBob=] and Sandy) fans and ''all of the [=SpongeBob=] slash-fans'' seem to constantly be at each other's throats whenever people start to discuss the pairings that they like and don't like (or at least the very militant ones are). The slash fans tend to ignore that WordOfGod said at one point that [=SpongeBob=] had a chaste crush on Sandy, the Spandy fans often ignore all of the HoYay, and everybody seems to ignore the fact that WordOfGod has also stated that [=SpongeBob=]'s [[UsefulNotes/{{asexual}} asexuality]].
* ''WesternAnimation/StarVsTheForcesOfEvil'': With romance rivaling the main myth arc in importance, ship wars were inevitable.
** The two largest combatants at the start of the show were Star/Marco (Starco) and Marco/Jackie (Jarco). Jarco shippers would usually claim that having the main characters get together is cliché and that Star and Marco's relationship should stay platonic. On the other hand, Starco shippers would claim that Marco has far better chemistry with Star than with Jackie. Plus, they have support from the actor of Marco himself (Adam [=McArthur=]), the fact that Star and Marco are loosely based on creator Daron Nefcy and her husband, and a season one episode where their souls were literally fused together. Marco and Jackie end up dating halfway through the second season, intensifying the war and even leading to a [[Webcomic/ShipWarAU fan webcomic]]... only for Season 3 to have Jackie officially break up with Marco, knowing that he has unrealized feelings for Star.
** This wasn't a win for Starco shippers quite yet though, as by that point, Star had gotten back together with her ex-boyfriend Tom, fulfilling the seemingly unlikely ship of Tomstar, and angering Starco and Jarco fans equally. And Marco got to deal with his own relationship issues once he came to terms with the fact that he has a crush on Star after all; since he doesn't want to ruin Star's relationship with Tom, we ended up [[FromBadToWorse feeding the fuel of ship wars]] by teasing Heckapoo/Marco (Marcapoo) and Kelly/Marco (Kellco).
** The fandom was ''heavily'' divided after "Booth Buddies" where Marco kissed Star... because they were trapped in a photo booth by someone who wanted them to kiss. And while Star was still dating Tom, and may or may not have enjoyed the kiss. A lot of fans complained that it was unfair to Tom, regardless of what pairing they shipped, with some Starco shippers feeling that the context of their first kiss ruined the ship for them. Meanwhile, others saw this as another victory, in spite of how awkward the circumstances were.
** While it was expected as an inevitability when Starco ended up being the final pairing, Tomstar fans (including Tom's own voice actor), weren't happy about how their ship ended. While Star and Tom end their relationship amicably, these fans argue it felt less like a mutual split and more like Tom having to end things due to [[StrangledByTheRedString Star suddenly becoming apathetic about a relationship she was wholly into just episodes prior]]. And this is after two seasons of Tom being shown as deeply devoted to making this second go at their relationship work and becoming a better person, even privately forgiving Star for kissing Marco behind his back and brushing it off when ''she'' gets mad at ''him'' upon finding out he learned about it.
* ''WesternAnimation/StarWarsRebels'': On the other hand, is fairly light on shipping (presumably due to the LighterAndSofter tone and the younger characters act less like {{Child Soldier}}s), with most emphasis being on [[OfficialCouple Kanan and Hera (Kanera)]]. A few circles ship Sabezra, with its Detractors shipped Sabine with Ketsu (Ketbine). Probably also helps that the LGBTFanbase from ''The Clone Wars'' carried over.
** The aforementioned Garasoka ended up not lasting long since [[ShipsThatPassInTheNight they ended up never interacting onscreen before Ahsoka left the cast]], as well as the growth of [[FoeYayShipping Kallus/Zeb]] (Kalluzeb) at the same time.
** Likewise, Agent Kallus/Minister Tua and the Grand Inquisitor/Minister Tua (and sometimes all three of them together) gained traction in Season 1, only to drop in popularity upon the airing of the Season 2 premiere to the point of NoYay because it turned out [[WeAREStrugglingTogether they all hated each other]], with the former ship [[ShipSinking sinking]] because Kallus guiltlessly helps ''assassinate'' her. Nowadays, the latter ship still has some of its shippers and [[DieForOurShip most are detractors of Kallus]] (and also don't want him to be in an any relationship at all, especially not Kalluzeb, [[BaseBreakingCharacter along with an issue over his character arc]]).
** Seventh Sister/Kanan was considered upon the announcement of the former character as well as who their voice actors were, but ended up not garnering much attention as the two barely interacted, the Inquisitors ended up with [[TheScrappy an unpopular reputation with their story arc]], and Kanera completely overshadowed it.
* ''WesternAnimation/StarWarsTheCloneWars'': [[LauncherOfAThousandShips Ahsoka]] is paired with ''every single male character on the show''. Lux/Ahsoka (Luxsoka), Captain Rex/Ahsoka (Rexsoka) and Anakin/Ahsoka (Anisoka) are the three biggest ones, but then of course [[FoeYayShipping Boba/Ahsoka]], [[LesYay Barriss/Ahsoka, Riyo/Ahsoka, Ventress/Ahsoka]], [[NoYay Bane/Ahsoka]] all exist and are somewhat popular. The show also has some very disturbing pairings being supported. Count Dooku/Ahsoka is what we're talking about here. Considering Ahsoka was a KidHero as well as a rolemodel to numerous young girls at the time (emphasis on ''kid'' and ''girl''), you kind of have to wonder if her LGBTFanbase resulted as backlash from the prevalence of Luxsoka (which garnered BrokenBase status as some felt that the two were StrangledByTheRedString) and the shipping of her with ''older men''.
** Expanded material would add [[MissingEpisode Nyx]]/Ahsoka (Nyxsoka), [[WesternAnimation/StarWarsRebels Zeb]]/Ahsoka (Garasoka), [[WesternAnimation/StarWarsRebels Seventh Sister]]/Ahsoka, and [[Literature/StarWarsAhsoka Kaeden]]/Ahsoka (Kaesoka).
** [[WordOfGod Writer Giancarlo Volpe]] has gone on record saying that the Barriss/Ahsoka vibes can be taken as romantic.
* ''WesternAnimation/StevenUniverse'': Amedot (Amethyst/Peridot) vs. Lapidot (Lapis/Peridot) shippers. This war got so bad that the writer of the episodes that first teased these ships (stating that they wrote Lapidot as if they were in a growing relationship, and Amedot as Peridot having a crush on Amethyst that led to them becoming close intimate friends, and that their stance on it might not be the other writers/storyboarders' stance on it), Jesse Zuke, eventually ''quit the show'' itself following constant fan harassment. Occasionally Jaspis (Jasper/Lapis) gets dragged into it.
* ''WesternAnimation/{{Superjail}}'':
** For a time on sites like deviantART, shipwars could get very vicious, ''especially'' if they involved male/female pairings vs. male/male ones (or more rarely, female/female). This would lead to some fans from either camp flinging stereotypes about the opposing one, with shippers of heterosexual pairings being called homophobes, and the shippers of homosexual pairings being accused of [[HetIsEw "oppressing het"]]. Not as bad as ''Danny Phantom'' in the end, but still mind-boggling.
** In the days of season 1, Warden/Mistress ("Misden"), Warden/Jared ("Jayden"), and Warden/Future Warden ("Wardencest"/"Timeshipping") went head-to-head, with Warden/Jailbot ("Warbot") also another option considered. Once Lord Stingray entered the picture in season 2, select fans of "Stingden" and Misden began arguing over which pairing would be more canon and which of Warden's nemesises was more worthy of him. This lead to both Mistress and Stingray [[DieForOurShip getting hate from the other's fans]] out of the idea that either one was in the way of their desired pairing. This seemed to die down a little after "Stingstress" [[spoiler: since the Mistress wound up sleeping with Alice.]]
*** A vocal minority of Warden/Mistress fans have also thrown potshots at Alice and those who ship her with either the Mistress (who they believe only Warden is entitled to) or the Warden (who only the Mistress is apparently entitled to). This was spurred on by the above episode.
** While the Warden/Jared vs. Jared/Charise disputes are less frequent or as overplayed as the above, it doesn't make Charise completely immune from being subjected to this and DieForOurShip by fans who insist that she's "in the way", secretly evil, or not as significant to Jared as the Warden would be. In turn, some Jared/Charise fans even jumped ship to the other pairing after season 3, feeling it'd be less likely for Jared to actually get together with her.
** In the least frequent but most baffling example of the trope, some fans go to war over whether the Twins are incestuous or whether they're more deserving of being paired off with women (sometimes even just pairing them off as an attempt to dissuade the Twincest). Seeing as there are very few female characters in the show, it leads to [[CrackPairing pairings that would be ridiculous anyway]], such as pairing one Twin off with Alice or the Mistress.
* ''WesternAnimation/TeenTitans'':
** ''Teen Titans'' was famous for ship wars during its run. Most notably, [[FanPreferredCouple Beast Boy/Raven]] shippers vs. Beast Boy/Terra shippers, [[SlapSlapKiss Beast Boy/Raven]] shippers vs. Robin/Raven shippers and [[OfficialCouple Robin/Starfire]] shippers vs. Robin/Raven shippers. All they need is a Starfire/Terra ship, and the MexicanStandoff will be complete. WordOfGod saying that any Beast Boy/Raven ShipTease was [[PlatonicWritingRomanticReading accidental]] gets scoffed at by fans. ''WesternAnimation/TeenTitansGo'' would cause the ship wars to start up again after years of rest due to actively teasing Beast Boy/Raven on several occasions (one episode even being called [[PortmanteauCoupleName BBRae]]), and the lack of mutual Beast Boy/Terra (Terra has her old manipulative comic book persona) and Robin/Starfire (Starfire openly rejects his advances).
** Cyborg was mostly left out of this. There was a quick Cyborg/Raven vs. Cyborg/Jinx ship battle, but it didn't last long, as most came to the conclusion that Cyborg and Raven had more of a sibling bond and that he was better with Bumblebee anyway. After Jinx pulled a HeelFaceTurn and started [[OfficialCouple dating]] Kid Flash, a rivalry developed between Kid Flash/Jinx shippers and Cyborg/Jinx shippers that still continues to this day. Interestingly enough, ''WesternAnimation/TeenTitansGo'' pushes Cyborg/Jinx as one of its definitive pairings.
** Parodied in the show itself; Control Freak is broadcasting a live feed of his DeathCourse to fellow geeky supervillains, and they briefly argue about whether Robin [[CrackPairing or Beast Boy]] is better for Starfire.
* ''WesternAnimation/TeenageMutantNinjaTurtles2012'' has a large one going on. A lot of fans are supportive of [[InterspeciesRomance April/Donatello]], but the OfficialCouple of most incarnations is Casey/April. The large amount of Apritello fans may be a result of the first season not having Casey. Once he became part of the show, many fans weren't happy and were willing to defend their fandom, while other fans jumped on the Capril ship and unsurprisingly retaliated. Tensions only heightened when the LoveTriangle came about.
* As [[http://trurotaketwo.deviantart.com/art/The-Fat-Controllers-problem-110937810 this fanart]] will demonstrate, not even ''WesternAnimation/ThomasAndFriends'' fandom is safe from shipping wars. It does not help however that that some of the episodes have hinted towards crushes between the engines (such as Rosie trying to follow Thomas everywhere in her introductory episode, or Thomas blushing on seeing Flora in her introductory episode).
* ''WesternAnimation/TotalDrama'' has a complicated situation, due to the huge cast and lots of ShipTease:
** The biggest one is between the original OfficialCouple, [[SlapSlapKiss Duncan/Courtney]], and the new canon, former FanPreferredCouple [[RelationshipUpgrade Duncan/Gwen]] [[spoiler:before their breakup much later]]. The fact that the latter got together thanks to Duncan cheating on Courtney doesn't help.
** [[DefrostingIceQueen Gwen]]/[[SingleWomanSeeksGoodMan Trent]], also originally canon, used to be heavily involved in this fray too before being [[ShipSinking sunk]]. They still tend to side with Duncan/Courtney as a [[ShipMates Ship Mate]], though, as do [[DoggedNiceGuy Cody]]/[[JustFriends Gwen]] supporters.
** LoonyFan Sierra, Cody's StalkerWithACrush, is the perfect ''casus belli'' of Shipping Wars. Many [[HoYay Noah/Cody]] and Cody/Gwen supporters despise her, though the more forgiving ones are willing to tolerate her after season three ends with her and Cody as JustFriends (and the resulting fact that she no longer makes his life a living hell).
* ''WesternAnimation/VoltronLegendaryDefender'':
** Shiro/Keith shippers vs. Keith/Lance shippers. The FoeRomanceSubtext of Klance vs. the respectful admiration of Sheith. The feelings of animosity can spark some serious fights in the vein of [[WesternAnimation/AvatarTheLastAirbender previous]] [[WesternAnimation/TheLegendOfKorra series]] the writers and producers worked on; except this time the lingo has been updated with accusations of either ship being abusive or pedophiliac (despite Keith being an older teen ''tops'', not a child), such is the way of shipping.
** Granted, with the reveal that Keith is legally an adult (the handbook places him as 18 at the start of the series), the age-related arguments have begun to shift towards Shiro/Keith being an unhealthy age gap rather than outright pedophillia-- though there are still a significant amount of people who claim it as such. Since Shiro is stated to be 25, this puts the age gap at 7 years. Unfortunately for those who hate the discourse, this means that it's a large enough gap to get on some people's red alert but small enough that others don't see a problem with it.
** At the start of Season 2, Keith and Allura had some moments that could be seen as ShipTease. More than a few Shiro/Allura, Shiro/Keith, and Keith/Lance fans got defensive and started complaining about it.
** Allura/Lotor shippers don't get along well with Allura/Lance or Allura/Keith shippers, since while Lotor receives a lot of Ship Tease with Allura, he has traditionally been a villain and enemy of Allura's, while Lance and Keith are heroic characters. [[spoiler:The latter's suspicions were proven correct in Season 6, when Lotor turns against Allura.]] Allura/Keith and Allura/Lance shippers don't get along well with each other either; the former, which was the OfficialCouple in all previous incarnations of the show, accuse the latter, which is the OfficialCouple in this continuity, of being a creepy and abusive DoggedNiceGuy relationship, while the latter insist Keith's at-times harsh treatment of Allura is also abusive and accuse the former of [[RonTheDeathEater misrepresenting]] Lance's treatment of Allura.
** When the series finale had a [[LastMinuteHookup last-minute wedding]] between Shiro and Curtis, a character who was so minor that most fans didn't even know his ''name'' at first, the pairing and the fans who liked it or were happy that Shiro at least got a happy ending with another man were attacked on all sides by Shiro/Keith and Shiro/Adam shippers who denounced it as a poorly thought-out attempt by the producers to make up for the backlash surrounding Adam's death and insisted that the man Shiro married ''should'' have been someone he had actual on-screen history and development with.
* ''WesternAnimation/XMenEvolution'' has a few interesting ones:
** [[AllGirlsWantBadBoys Lancitty (Lance/Kitty)]] vs. [[PlatonicLifePartners Kurtty (Kurt/Kitty)]] is the biggest one and dates back to the start of the fandom. Some Kurtty fans like to bash Lance as a violent bad boy who is all wrong for the innocent and sweet Kitty and should be with someone like Wanda or Tabitha, while DoggedNiceGuy Kurt is the one for her (sometimes depicting him more violently than usual and being rather immature about it). Lancitty fans will point out that Kitty is attracted to Lance, and never showed the slightest romantic interest in Kurt, who is in a relationship with Amanda (sometimes agressively saying 'ITS NEVER GOING TO HAPPEN' and be rather immature about the matter as well). They are also quick to remind anyone they have {{canon}} behind them as the OfficialCouple since Lance and Kitty are hinted to get back together at the end. And, that's not even mentioning the Piotr/Kitty fans. Usually, they're spared by the other fans due to Piotr's little screentime. But the fact he's Kitty's comic love interest, and in a few scenes at the end of the third season Kitty and him proved to work well together, he's just as much up for grabs by the less tolerable fans. Sometimes, he'll get off light with just a casual "It didn't happen", sometimes he'll get a "he was too old for her" (his age wasn't ever stated, but he appeared to be only around Scott and Lance's age), but, sometimes he'll just get treated like garbage, or OutOfCharacter moments from the comics will be given as 'evidence' of him being wrong for Kitty.
** Another one is Scogue (Scott/Rogue) vs. Romy (Gambit/Rogue). Rogue had a crush on Scott that lasted for three seasons of the show; this pairing proved very popular, much more so than Scott's always inevitable hookup with Jean. But it was challenged when Rogue's longtime comic boyfriend Gambit appeared on the show. Now, every detail about Scogue is bashed (including its name; seriously, some cite that "Scogue" or "Rott" sounds terrible) by the Romy fans.
** Jott (Scott/Jean), especially by Scogue fans. Or Jean herself, who apparently is a slutty evil AlphaBitch in the view of rabid Scogue fans who think PopularIsDumb despite Jean being portrayed sympathetically in the show, or creepily overproject their own teenage experiences on the LoveTriangle: Rogue the Misfit is automatically good, Jean the pampered but sweet girl is automatically bad, Scott is Rogue's "prize penis" for being the Cool Girl, etc.
* In the ''WesternAnimation/YoungJustice2010'' fandom there are many ship wars, but the main ship war being Spitfire (Artemis/Wally) and Traught (Artemis/Robin). [=BirdFlash=] (Wally/Robin), Chalant (Robin/Zatanna), and Babs/Robin often get caught in the crossfire. Some people have compromised with an OT3, Museum Heist (Robin/Wally/Artemis), which occasionally expands into four with Babs or Zatanna.
