* The original anime flame war: "Anime is just Japanese for "cartoons" vs. "Anime is a special artform all its own and utterly and completely different from Western animation".
* There is an ever present opinion that though you may draw in the style of manga, though your comics may read from right to left, you can ''never'' call your comic a "manga" unless you are Japanese but if you make an animation in that style or any other you can call it anime [[RealityIsUnrealistic because to the Japanese it's always named anime]].
* AnimationAgeGhetto can often rile up flame wars, especially when it comes to anime.
* SubbingVersusDubbing. The issue is aggravated by the fact that some [=DVDs=] are released as sub only.
* Character names when a series is being translated [[SpellMyNameWithAnS from one language to another]]. ([[Manga/DeathNote Raito or Light]]? [[Anime/PrincessTutu Ahiru or Duck]]?)
* Asking "Why is ''Manga/{{Naruto}}'' such a crap anime" on any anime forum gets 3 different responses; non-fans saying it is, fans saying it isn't and a 3rd group that actually look at the question and point out its foibles and short comings, and try to answer it logically and factually. The 1st and 2nd group will fight, and the 3rd inevitably joins in, and can take either side.
** Just ''try'' pairing ''any'' two characters together: 90 percent of the time, you'll get ShipToShipCombat.
** ''Never'' try to favor Hidan or Shikamaru above the other. The [[ScarsAreForever scars will last a lifetime...]]
* ''Anime/DragonBallZ'' ... so many to count, but simply ... Frieza Saga vs. Cell Saga vs. Buu Saga.
** Calling ''Anime/DragonBallGT'' canon to someone who disapproved of it, due to its splintered relationship to the past two ''Dragon Ball'' series.
** Never attempt to defend a character (especially a human) who is hated by [[BaseBreaker half of the fandom]] or a character who is hated [[TheScrappy by the majority of the fandom, ever.]]
* Fansubs (and by extension, piracy): Good or bad?
* ''{{Hellsing}}'' anime vs. ''Hellsing'' manga/OVA. And, [[InternetBackdraft may Alucard have mercy on your soul if you mention you like]] ''[[FandomHeresy both]]''.
* Dissing the [[MemeticBadass great Kamina]] from ''Anime/TengenToppaGurrenLagann'' brings swift destruction upon you.
* Discussing ''Manga/OnePiece'' vs. ''Manga/{{Naruto}}'' (and sometimes ''Dragon Ball'', ''Manga/{{Bleach}}'', and lately ''Manga/FairyTail'' added in) has been a legendary conflict for fans of either series for the past 14 or so years they've been running. It's a battle of what "character type" the fans like most, ''One Piece'' being pirates, ''Naruto'' being ninjas, ''Dragon Ball'' more-or-less being aliens, ''Bleach'' being samurai, and ''Fairy Tail'' being wizards (kind of).
* One of the ''most offensive [[FandomHeresy heresies]]'' you can use towards an anime is calling a [[FourKidsEntertainment 4Kids]] [[{{Bowdlerise}} dub]] of one good.
* Even ''implying'' that any {{Gundam}} is better than another ''will'' spark a flame war that can and most likely will [[ForeverWar span hundreds of pages]], the most likely outcome of these flame wars will either be a Mod locking the thread, or the comments section of a video being closed. Though there have been times where there is a [[ReconcileTheBitterFoes peaceful]] [[IWillFightNoMoreForever resolution]] in which almost every side will come to an agreement and end up having a pleasant conversation while any [[TheRemnant ragers]] will continue arguing amongst themselves.
** For the UC fandom,any mention of "who was right" in the One Year War will cause a major flame war.
* Let's face it. The Streamline dub of {{Anime/AKIRA}} wasn't the best. In fact, it was so bad that the [[Creator/KatsuhiroOtomo original creator]] as well as the company and director behind the dub admitted to not liking it. However, [[FlameBait any mention of the Pioneer dub around fans of the original dub will result in you]] [[Film/TheDarkKnightRises going out like]] {{Franchise/Batman}}. Any video containing footage of the new dub [[YouCantFightFate WILL]] be berated by the Streamline dub-fans as 'soulless' and 'emotionless.' And, of course, this come right back round with the Pioneer dub-fans defending it like the friggin' Alamo. Remember, dear children, that the Alamo fell...but not without a fight.
** There are similar wars about the different dubs for the Miyazaki classics ''CastleInTheSky'', ''MyNeighborTotoro'', ''KikisDeliveryService'', and ''PorcoRosso''. All four had previous dubs distributed by Streamline. While Carl Macek handled the older dubs of ''Totoro'' and ''Kiki'', ''Laputa'' and ''Porco'''s older dubs were produced by unknown studios. Macek wanted to make better results for Miyazaki because he thought the '80s dub of ''Laputa'' was rushed, "phone-booked", and not very well done. Of course Disney redubbed all four movies, but be careful about praising any of them, particularly ''Laputa'' and ''Totoro'' to fans of their older counterparts; they will go on and on about how "superior" and "perfect" they are to their "horrible, butchering" Disney counterparts. Even on videos containing footage from said dubs. And then there are Disney dub-fans defending them.
