!!Both Series
* AlternateCharacterInterpretation: Both series have this in spades. Both canons have their own takes on the characters and themes of the story. Add the multitude of fandom interpretations and head canons to that, and you have a colorful hodge-podge of different (and sometimes [[TheyChangedItNowItSucks conflicting]]) ideas and analyses. This in addition to both versions of the story being ''very good'' and having passionate fanbases, has caused many a [[FlameWar flame war]].
* BaseBreaker:
** Envy: [[DracoInLeatherPants Lovable gender-confused palm tree with a completely acceptable excuse for his/her psychopathy]] or monster who doesn't deserve a bit of the fandom? Moreover, [[spoiler:was Roy justified in his actions when half-fighting, half-brutally torturing him/her or was it absolutely horrific and unethical?]]
** Edward Elric: Obnoxious BrattyHalfPint or total MrFanservice?
** Along the same lines, is Al a good foil for Ed, or just really, ''really'' annoying?
* CompleteMonster: This trope has [[Monster/FullmetalAlchemist its own page.]]
* CrazyAwesome: Armstrong and Barry The Chopper in both series... but for Barry, this trope applies better in the manga version.
* DieForOurShip:
** Rose for those who ship Ed and Winry.
** On top of Rose, Winry has also been on the receiving end of anger from YaoiFangirls because of this trope - although the fact that she's close to both Elric brothers means some of them will just [[ShipMates ship her with the other one]] instead.
** Mostly [[SubvertedTrope subverted]] with Riza, perhaps because her relationship with Roy is close enough to the line [[WillTheyOrWontThey between platonic and romantic]] (in the manga/''Brotherhood'' - it doesn't get elaborated on much at all in the 2003 anime) that fanfic writers can easily shift her into the former role if they'd rather Roy be [[HoYay with Ed or Hughes]].
* FanPreferredCouple: FMA has a lot of ShipToShipCombat, but the ''single'' most popular couple in the fanbase (at least in terms of amount of fanfiction/fanart dedicated to each) is [[HoYay Roy/Ed]], especially among Japanese fans.
* FashionVictimVillain: Envy, and Wrath in the 2003 anime.
* FandomRivalry: 2003 vs Brotherhood.
* GatewaySeries: The 2003 series was a major part of the mid-00s AnimeBoom. Both series have turned a lot of fans on to anime and have a lot of appeal even outside of the otaku subculture. It doesn't hurt that the franchise is a Toonami flagship.
* GermansLoveDavidHasselhoff: Maes Hughes is very popular with the American fanbase, much to the surprise of the Japanese creators.
* HoYay: [[HoYay/FullmetalAlchemist Has its own page]].
* IronWoobie:
** [[StealthPun Alphonse]], Edward, Izumi, Lan Fan, Alex Armstrong, Hawkeye, ''Mustang''... oh, ''almost every good guy''.
** The trope might as well be called "Fullmetal Woobie".
** [[spoiler: Armony]] from the first PS2 video game.
* ItWasHisSled: [[spoiler:Hughe's]] death is one of the most well known in anime and almost everyone who has gotten into the series since the mid 2000s knows it.
* LauncherOfAThousandShips: Ed. Al. Roy.
* LGBTFanbase: The series is very popular with gay fans of the BaraGenre due to a preponderance of characters who fit TheBear and BigBeautifulMan archetypes. Ironically this is the result of AuthorAppeal on the part of the mangaka, who is a [[PeripheryDemographic straight female]].
* MemeticSexGod: Roy Mustang often has this effect in fanfiction, which, to be fair, is not that dissimilar from [[TheCasanova his character in the actual show]] ([[spoiler: although, it gets subverted in the manga/''Brotherhood'']]). The difference is in fanfiction, he tends to have this effect [[EvenTheGuysWantHim regardless of gender]], whereas in the anime we only see it happen to women (and in fact, many of the men around him can't stand him for stealing their girlfriends).
* MoralEventHorizon: Shou Tucker turning his ''daughter'' and the family dog into a chimera. Some even believe he had ''already'' been past the [=MEH=] back when we first met him, as he had already done the same thing to his wife.
* OnlyTheCreatorDoesItRight: Some fans of the manga feel this way about the 2003 series; conversely, part of the 2003 anime's fanbase considers it [[AdaptationDisplacement the far superior work]]. The majority falls somewhere in the middle, but the flame wars tend to drown them out.
* PortmanteauCoupleName: Royai for Roy Mustang/Riza Hawkeye, Edwin for Edward Elric/Winry Rockbell, Royed for [[ExactlyWhatItSaysOnTheTin Roy/Edward]], Hyuroi or Hyuroy for Roy/Maes Hughes, [=LingFan=] for Ling Yao/Lan Fan and [=AlMei=] or [=AluMei=] for Alphonse Elric/May Chang.
* ShipToShipCombat: Royai vs. Royed, Edwin vs. Royed, Edwin vs. Alwin, Royai vs. Hyuroi...let's face it, it's all over this fandom. But particular mention goes to Edwin vs. Ed/Rose, the mother of all FMA ship wars coming off of the 2003 anime.
----
!![[Manga/FullmetalAlchemist Manga and Brotherhood]]
* AlternateCharacterInterpretation:
** Did [[spoiler:Bradley's]] last words show that he really did care about his family or that he didn't care about them at all? It's actually fairly obvious but people love to argue. On [[spoiler: Bradley]] in general: Is he evil? Or just a PunchClockVillain that fully embraces what he is?
** And then there's Truth. GodIsEvil? GoodIsNotNice? Divine distributor of ironic punishment or just does it ForTheEvulz? It's up for debate.
** [[{{Omake}} 4 Koma Theater]]. [[NightmareFuel Scar]]. [[CrowningMomentOfFunny Winry’s Parents]]. Will never be able to look at Scar the same way again. We need a “Crowning Moment of Ridiculous” page, but “Funny” will do for now.
** Was Miles actually right about Grumman planning to let Roy and Olivier take the heat as traitors, while he swooped in to take over the government?
** It's generally agreed from TheReveal about [[spoiler: his spy network]] that Roy Mustang is exaggerating his reputation as TheCasanova at least ''somewhat''. But the ''degree'' to which he is - whether he's actually ''completely'' hopeless with women [[SingleTargetSexuality who aren't Riza]] (or even [[ArmoredClosetGay not into any women at all]]), or he just dates about the same amount as a typical affluent, attractive, single 29-year-old - is a question that's caused a surprising amount of InternetBackdraft among the fandom. Roy's sex life is apparently SeriousBusiness.
* AngstWhatAngst: Ed and Al, to the point that Winry has to invoke HeWillNotCrySoICryForHim far more often than is healthy over the first half of the series.
* {{Anvilicious}}: The flashbacks of the extermination of Ishbal have a distinct ''''[[WarIsHell war is bad]]'''' vibe to them. [[TropesAreNotBad Not that it wasn't completely accurate.]]
* AwesomeMusic: [[AwesomeMusic/FullMetalAlchemist Has its own page]].
* BaseBreaker: Much like Dante below, Father qualifies as this. Is he a threatening villain that [[spoiler: nearly succeeds in his plan]], or is he just a GenericDoomsdayVillain that lacked the charm Dante had.
** May became disliked by some fans during the last arc. While understandable that finding a Philosopher's Stone to save her clan is important, the fact that she listened to [[ObviouslyEvil Envy]] and was guilted into going back to Amestris by a Homunculus who she has seen turn into a monster and has shown not to be trusted, made it hard for some fans to stay attached to her. Yet, at the same time there still some fans that admire her for choosing to save Hawkeye, rather than pursuing the stone which can save her clan and protecting everyone against Father when there Alchemy was rendered ineffective and they we're all vulnerably against him at the time.
* BrokenBase:
** Is ''Brotherhood'''s animation style bold, crisp, and original, or ugly, washed out, and far too cartoony?
** Was the manga's ending incredible or did it feel like fanfiction?
** Is ''Brotherhood'' a better adaptation of the manga or not? Somewhat of a separate question from the "which canon is better" debate, since even a lot of people who preferred the manga found things to dislike about ''Brotherhood'' adaptation-wise.
** Are Roy and Riza 'obviously' in love with each other or just platonic? [[TakeAThirdOption Or is it truly ambiguous?]] Same with Al and May.
** In more recent years, a big debate has sprung up over whether the manga (and ''Brotherhood'' by extension) are truly deserving of their feminist cred. The results have been... explosive, to say the least.
* DracoInLeatherPants: Envy, Kimblee and Lust in particular.
* EarWorm: Any of the ''Brotherhood'' openings, especially #3, Golden Time Lover.
* EnsembleDarkHorse:
** Though the series is full of [[GushingAboutCharactersYouLike likeable people]], Lan Fan is very popular among the ''Brotherhood'' fandom, despite only being a secondary character.
** Ditto Sheska, who many fans lament the disappearance of in the manga, [[BrotherChuck where she simply goes "poof" plotwise]]. The fact that she looks like a female [[Anime/NeonGenesisEvangelion Kensuke Aida]] doesn't help matters at all.
** Being an EnsembleDarkhorse has been passed down the Armstrong line for generations!! Both the Major and his sister are definite favorites of the fandom.
** Amongst the bara fans, Scar is a big time example. Darius and Heinkel were also popular enough in fanart to get a doujinshi.
** Greed is probably the most popular Homunculus behind Envy, especially considering how minor of a character the former is compared to the latter.
*** In the manga poll, [[spoiler:Greed I and II]] were ranked the 12th and 13th most popular characters respectively (the highest ranked [[spoiler:Homunculus, only behind Envy]]). If they were both ranked as a [[spoiler:single character (since they ''are'' the same person), then Greed would have scored higher, maybe even higher than Envy]].
** [[OverprotectiveDad Maes]] [[BadassNormal Hughes]], for being a hilarious DotingParent of a KnifeNut.
* EvilIsCool:
** Envy is a dick in every sense. They're just so damn awesome at it that the fans tend to find them [[LaughablyEvil amusing anyway.]] Kimblee also fits. Greed also seems to [[LampshadeHanging lampshade]] this trope as he [[HeelFaceRevolvingDoor alternates]] between Cool Evil and Cool Good at massive FaceHeelRevolvingDoor speed.
** There's Wrath. A guy who can do all those feats of implausible awesome should have been here by default. [[spoiler:He took down ''a tank. ''With a '''sword.''']]
** Most of the Homunculi, then.
* EvilIsSexy: Lust, obviously. And this canon's version of Kimblee has a ''huge'' number of fangirls.
* FauxSymbolism: Several Christianity references in the manga, most obviously the names of the homunculi. Even so, Arakawa says that "Christianity doesn't exist in that world".
* FoeYay: Roy and Olivier.
* FunnyAneurysmMoment:
** In one of the omake after [[spoiler:Pride consumes Kimblee, Pride is seen spitting him out in disgust.]] A few volumes later [[spoiler:Kimblee ends up depowering Pride from within and allowing Ed to reduce him to his true form in disgust.]]
** Any moment where Ed's shortness and his sensitivity about it is played for laughs, after the revelation that [[spoiler:it's because Al's body has been drawing nourishment from him to survive]].
* GeniusBonus: Van Hohenheim is named after [[http://en.wikipedia.org/wiki/Paracelsus Paracelsus]], a.k.a. Phillippus Aureolus Theophrastus Bombastus ''von Hohenheim''. In-story, the dwarf in the flask [[spoiler:i.e. Father]] names him Van Hohenheim but initially suggests he take on the name Theophrastus Bombastus.
** Executive Order 3066, Bradley's order to wipe out the entire Ishvalan people, is named for a [[http://en.wikipedia.org/wiki/Executive_Order_9066 not-nearly-as-bad-but-still-a-pretty-huge-dick-move]] RealLife executive order.
** Lust being incinerated to death echoes Dante's ''Purgatorio'', in which the lustful are made to pass through a wall of cleansing fire before passing from Purgatory.
* HarsherInHindsight:
** The scene in Brotherhood where Ed and Al see Bradley while talking with his wife and son is [[DramaticIrony already quite unsettling]] for them because they know that [[spoiler:he’s a homunculus]], but it gets even worse if you know that [[spoiler:his son is a homunculus, too. One has to feel sorry for Mrs. Bradley]].
** In a flashback to Xerxes, the king ordered a "waterway" to be dug around the kingdom. One of the workers comments "Nothing less to be expected from the King of Xerxes, he even thinks about commoners like us!" [[DramaticIrony Eeeeugh]].
* HellIsThatNoise: [[spoiler:When the [[NightOfTheLivingMooks mannequin soldiers]] are awakened during [[ApocalypseHow the Promised Day]]]]. If that first scream from [[spoiler:one of the mannequins]] was from a character in any series being tortured by {{Satan}} in Hell, it would've been among the more terrifying examples. Which, considering their very state of existence as well as the BigBad [[SatanicArchetype of the series]], [[FridgeBrilliance well]]…
* HilariousInHindsight:
** Ed mentions that if he ever went to see God, he'd probably get sent right back to earth. [[spoiler: Guess what he does twice; once to escape certain doom, and again to save Alphonse in the final chapter.]] And that's without accounting for the very start of the story in the first place, meaning he's secretly speaking from experience [[spoiler:and then it happens again]].
** Creator/TravisWillingham and Creator/LauraBailey, who are the dub voices of Roy Mustang and Lust respectively, are now married. With that knowledge, just try to watch episode 19 without laughing at some point. This also makes Mustang talking about bringing Lust onto her knees into [[DoubleEntendre a whole 'nother context...]]
** Years ago, [[Creator/VicMignogna Vic]] and [[Creator/CaitlinGlass Cait]] did a [[http://www.youtube.com/watch?v=IMyY7Qu5XTc funny/adorable marriage proposal skit]] at a con. [[spoiler: [[WackyMarriageProposal We all know the last scene of the manga]].]]
** J. Michael Tatum took over Scar's voice for the ''Brotherhood'' dub. He and Winry's actress Caitlin Glass had already played a romantic couple in ''LightNovel/{{Baccano}}''.
* JerkassWoobie: Ed, Mustang, the second Greed, Scar, [[spoiler:Pride]] and Envy.
* LevelBreaker: The final fight had every character being as [[LargeHam hammy]] and [[ChewingTheScenery taking as much screentime]] as possible.
* MagnificentBastard:
** Kimblee and Father.
** Roy Mustang always has a plan when he is involved, and often pulls them off with elegance and style.
* MemeticMolester: Mr. Garfiel in the 4koma skits. No one is safe. Not even Ed.
* MemeticMutation: Regarding everything that happens once [[spoiler:Father successfully activates the national transmutation circle]]:
-->[[Anime/NeonGenesisEvangelion I know, I know I've let you down]]\\
[[LyricalDissonance I've been a fool to myself]]...
** Major Armstrong's CatchPhrase "X HAS BEEN PASSED DOWN THE ARMSTRONG LINE FOR GENERATIONS!"
* MisaimedFandom: [[spoiler: Roy's]] [[CurbstompBattle curbstomp]] of [[spoiler: Envy]] was enjoyed a little ''too'' much by the fandom. [[spoiler: Envy]], from the 2003 series, was a massive KarmaHoudini who managed to get away with ''a lot'' of atrocities without any real retribution, so many saw [[spoiler: his torture at the hands of Mustang]] as belated LaserGuidedKarma. WordOfGod is that the intent was to show that [[spoiler: Roy]] was getting close to succumbing to HeWhoFightsMonsters.
** Now that the anime has come out, [[spoiler: Roy's]] mad rage and [[spoiler: Envy's]] pain and fear are easily evident in their voices, so this is less of a problem.
* {{Moe}}:
** May Chang. Small and cute. Also badass, but that's [[BadassAdorable another story...]]
** Also Nina, Elysia, and any cat that finds its way into Alphonse's armor...
** Lan Fan can be pretty Moe in her more vulnerable moments, particularly [[spoiler: while she's recovering from losing her arm]].
** Selim Bradley, [[spoiler:even after TheReveal that he's a villain]].
** Arakawa herself doesn't seem too fond of the concept, having complained about in one volume's opening pages.
--> '''Hiromu Arakawa:''' MOE, MOE, MOE! Everything's coming up MOE! Enough already!
* MoralEventHorizon:
** Bradley not only headed Amestris during the rebellion, but rejected Loug Lowe's proposal to sacrifice his own life to end the violence, saying one life is only equivalent to one life (and presumably intending to kill ''all'' the Ishvalans).
** Envy [[spoiler:killing Hughes and almost getting Maria Ross executed for it]], and starting the Ishval rebellion by killing a child and framing an innocent soldier for it (who got court-martialed and presumably executed) and if the later wasn't enough, when Ed and Al find out this from him, he ''proudly gloats'' about this act.
** Homunculus Father crossed his [[spoiler: in his backstory when he manipulated Hohenheim, the King of Xerxes, and the King's Alchemists into making PhilosophersStone bodies for both himself and Hohenheim out of [[PoweredByAForsakenChild every single soul in the country]]. Seeing the MO of this guy's [[SatanicArchetype Satan-based objective]] in action is truly [[NightmareFuel horrifying]]]].
** Pride almost definitely crossed it when he [[spoiler: ate and killed one of his allies just to become more powerful than he already was.]]
* {{Narm}}:
** The first opening sequence of ''Brotherhood'' is mocked for the bit where Ed loses his arm and leg, Al loses his whole body, and Winry loses...her balance.
** The fifth opening might have worked had it come earlier, but by the time it arrives it's pretty absurd to see a show that's become wall to wall {{HSQ}} moments suddenly get such a soft, gentle theme song.
* NarmCharm:
** [[spoiler: After Father swallows Hohenheim, he looks like he's pregnant. This is offset by the fact that Father's OneWingedAngel is '''''absolutely terrifying.''''']]
** [[spoiler: Father's appearance before swallowing a god]] also qualifies. How ridiculous it looks only makes the shit that much crazier.
** The aforementioned eyecatches actually manage to come off as pretty badass in episode 44, where they're played just after [[spoiler:the title character's triumphant and unquestionably awesome reentry into the series after being missing for an episode.]]
** The [[LargeHam ham-tastic delivery]] Father's dub voice actor does as he [[spoiler:pulls God down to earth]] would normally induce huge spiels of laughter in any other scenario. In this one, it induces that nervous, [[TheseAreThingsManWasNotMeantToKnow Oh-my-god-I-feel-my-brain-breaking]][[BrainBleach -MAKE-IT-STOP]] sort of laughter.
* NightmareRetardant: If something terrified you in a volume, chances are the omake will make fun of it in a such a way you'll never be able to take it seriously again.
* ParanoiaFuel: The Homunculi; they control everything. ''Everything''. The massive war that happened years ago? The Homunculi started it. The horrible human experiments? The Homunculi started them. The president? He's one of them, and [[spoiler:so is ''his son'']]. There is almost ''nothing'' horrible happening in Amestris that the Homunculi ''didn't'' cause.
* RuleOfSymbolism: When Roy is talking about [[spoiler: how all his loyal men (and woman) have been taken away, while going over the chess pieces representing them, the bishop in the panel is tipped onto its side.]]
%% [[spoiler: During Father and Hohenheim's initial fight, notice the dragons they use against each other. Notice a difference?]] %% Zero Context Example. Give more information before putting back in.
* SuperlativeDubbing:
** The English dub is widely considered so, like its predecessor before it--possibly more so as nearly all the original cast is brought back (unlike in the original Japanese track) and have experience for the roles. Even the newcomers for Al, Scar, etc. manage to capture the spirit of their characters. In particular, Travis Willingham's deeper and more confident delivery as Mustang is considered a big improvement, as he'd had several years to hone his craft since doing the first series.
** The same applies for Latin American dub. The voice acting for the series is considered great. And many voice actors reprised their roles in both series.
* TheyJustDidntCare: A criticism frequently leveled at ''Brotherhood'', mostly on account of the "rushed" early episodes, which are an unfortunate side effect of the 2003 anime, which is more well-known, slowing down the events of said episodes to stretch them out, making the manga's quicker version seem like not enough time was spent on them.
* TheyWastedAPerfectlyGoodCharacter: Greed has some of the least screentime among the homunculi, being one of the last homunculi introduced [[spoiler:and among the first to die.]] This is despite his being one of the most [[DefectorFromDecadence unique]] [[HiddenHeartOfGold antagonists]] [[ALighterShadeOfBlack in]] [[EvenEvilHasLovedOnes the]] [[BenevolentBoss series]] and having one of the most iconic battles in the franchise. [[spoiler:Even his successor, Greedling, has some pretty noteworthy personality and stylistic differences compared to him, so it's not exactly fair to say it's a straight comparison.]]
* UglyCute:
** Envy's chibi true form is guaranteed to make you giggle or want to huggle him/her [[spoiler:even when s/he's being broiled alive]]. Perhaps even more in that case. Also, Gluttony.
** Slicer could count, when he's reduced to just a helmet.
* UncannyValley:
** The cyclops army.
** Then there's the [[spoiler: reincarnated Xerxians]]. Even the characters got a bad vibe when they showed up.
** When [[spoiler: Al is trapped in the dome with Pride and allows Pride to beat out morse code on his head ''for hours'' until reinforcements show up to free him. Al is naive and trusting to a fault but surely he's been around the military enough to figure out there was some kind of foolery going on there.]]
* {{Wangst}}: Al's serious consideration that he might just be a fake-soul-in-armor that Ed created, and Winry and Pinako are in on the joke.
* WhatAnIdiot: When the heroes, after long enmity and a fight, [[spoiler:''finally'' reduce Envy to a mostly-helpless [[EldritchAbomination larval green thing]], they... put him in a jar and give him to May Chang so that she can save her family's fortunes with the secret of immortality]]. There are ''several'' problems with this: 1) Although May, Ed, and [[spoiler:a reforming Scar]] are not the kind of people to kill a helpless opponent, the soldiers [[AndZoidberg and Yoki]] should have fewer reservations, particularly as [[spoiler:Envy]] has been incredibly dangerous, and immediately demonstrates that he is only ''mostly'' helpless. 2) The secret to immortality that [[spoiler:Envy]] knows involves some really nasty, evil things and there's no good reason to think that he knows a better method. [[spoiler:Edward has already refused to use a Philospher's Stone because of it, as has May herself, not to mention how most of Scar's people were literally ''killed for it''.]] Thus, none of them should be okay with it being given to [[spoiler:an Emperor who May had said earlier wouldn't hesitate to use it]]. 3) They're sending [[spoiler:Envy off with an unsupervised kid. May can [[BadassAdorable handle herself in a fight]], yes, but she is soft-hearted and Envy is an excellent deceiver.]] In conclusion, nobody at all should be surprised that [[spoiler:Envy talks May into a nest of zombie-like abominations that he uses to regain his full power]]. It's an IdiotPlot to ensure that both May and Envy will be in Central in the final arc.
* TheWoobie: Half of the sympathetic portion of the cast need hugs.
* {{Woolseyism}}: Xing's answer to alchemy (''renkinjutsu'') is ''rentanjutsu''. This word refers to [[http://en.wikipedia.org/wiki/Chinese_alchemy Chinese alchemy,]] but actually using something like "Oriental alchemy" or "Xingese alchemy" would get pretty stale and unwieldy after a while. The ''rentan'' refers to the goal of Chinese alchemy, the elixir of life. Drawing off of this, Funimation dubbed it as "alkahestry", after [[http://en.wikipedia.org/wiki/Alkahestry alkahest]]. As a universal solvent, alkahest was another hypothetical goal of alchemy and would have had valuable medicinal applications; [[GeniusBonus if you understand the reference]], "alkahestry" manages to convey Chinese alchemy's greater concern with medicine than with gold and sounds exotic next to "alchemy". The substance was supposedly invented by Paracelsus, whose birth name was Von Hohenheim, and the fictional Von Hohenheim was the inventor of Xingese alkehestry.
----
!! [[Anime/FullmetalAlchemist 2003 Anime]]
* AdaptationDisplacement: Even a few years after ''Brotherhood'', this is usually where casual anime fans' minds go when someone mentions "Fullmetal Alchemist". At least, [[GermansLoveDavidHasselhoff in the West]].
* AngstWhatAngst: Being [[spoiler: kidnapped and nearly killed by a serial murderer]] would traumatize most people for life, but [[spoiler: Winry]] seems to bounce back pretty quickly.
* AlternateCharacterInterpretation: Hohenheim gets a lot more of it here than he did in Brotherhood (where he's seen as more unambiguously benevolent): is he a wise [[TheAtoner atoner]] who feels bad for [[spoiler:all the [[BodySurf Body Surfing]] he's done]] or a suicidal JerkAss whose excuse to [[ParentalAbandonment abandon]] his children and wife Trisha doesn't cut the test and who [[spoiler:unintentionally helped the [[ThoseWackyNazis Nazis]]]].
* AssPull: It's hard to think of the AlternateUniverse twist as anything other than this, considering the complete absence of any foreshadowing, and the amount of FridgeLogic it raises in regards to the Gate of Truth and how Alchemy functions.
* BaseBreaker:
** Envy, Wrath and Rose are among the most polarizing characters. In the case of the latter, this is probably why she suffers DieForOurShip more often than Ed's other love interests (with the exception of [[TheScrappy her double]] in ''Conqueror of Shamballa''). In Wrath's case, he and Pride are not well liked as "replacement Homunculi" (ironically, [[spoiler:they're little more than a flip-flop of the manga version, where ''Wrath'' is the president and ''Pride'' is a creepy little kid]]), and Pride/[[spoiler:King Bradley]] in particular is hated for [[spoiler:going through a mix of serious BadassDecay and AdaptationalVillainy]]. Sloth, however, has caught less heat from the fandom.
** [[spoiler: Dante]] as a BigBad is often a lightning rod for the debate over [[BrokenBase which anime is better]]. Some fans of ''Brotherhood'' believe that she's less interesting and imposing than Father; however, just as many prefer her over Father, praising her abhorrent selfishness and her role as Edward's ShadowArchetype. Most fans seem to agree that each fits their respective continuities, and that which one you prefer ultimately comes down to personal tastes.
* BrokenBase:
** Is [[Anime/FullmetalAlchemist the 2003 anime adaptation]] the superior work, merely a very well-done PragmaticAdaptation or [[TheyChangedItNowItSucks a completely unacceptable mess that perverts the original source material]]?
** Was the 2003 anime's ending excellent and original, just passable, or a convoluted mess?
** Is Winry's and Edward's relationship [[LikeBrotherAndSister familial]] or romantic?
* ContestedSequel: Some fans view TheMovie as a touching send off to the characters that ties together most of the loose ends left over from the series. Others see it as a kick in the junk that resolves nothing and simply screws everyone over worse than they were screwed in the series.
* [[CrowningMusicOfAwesome Crowning Soundtrack Of Awesome]]:
** Michiru Oshima's score is considered to be a masterpiece. The openings and endings aren't anything to sneeze at either.
** Several tracks stand out in particular, such as Bratja and Dante's various themes.
** the Kelas
** "Regret", the song played entirely on the harmonica that plays during Mustang's flashback of the Ishval war in Episode 13.
** [[http://www.youtube.com/watch?v=kwY4lilrJv4&feature=related "YOU'RE GETTING ATTACKED BY GERMAN ZEPPELINS, HAVE SOME BEETHOVEN".]]
** They used Chopins etude 10.03 for the final scene at the Gate and for Edwards last appearance in the show. The piano piece is accompanied by strings and it's heartbreakingly beautiful. (and the etude often goes by the handle "tristesse". Well played, Oshima, well played.)
* CultClassic: For many of its fans.
* DarknessInducedAudienceApathy: In comparison to the more optimistic manga/''Brotherhood'', many viewers complain about this during the final quarter.
* DesignatedHero: Psiren, the titular character of "The Phantom Thief". See UnintentionallyUnsympathetic below.
* DesignatedVillain: Ed [[TemporarilyAVillain temporarily]] plays this role in "The Phantom Thief"; he's supposed to seem like an InspectorJavert for wanting to track down and arrest Psiren, but given the fact that she's a thief, a liar, is causing property damage and ''tries to kill him later'', it's hard to see his actions as unjustified.
* DieForOurShip: [[TheWoobie Rose]] gets it a lot from some Edwin shippers and YaoiFangirls. Even with all the horrible things that happened to her, getting an [[AscendedExtra expanded role in this version]] did not help her with shippers. And in turn, a lot of Ed/Rose fans hate Winry; YaoiFangirls generally tend to leave her alone, though, as it's more common for them to make [=AlWin=] ShipMates with [=RoyEd=].
* DracoInLeatherPants: Envy gets even more of this than he does in ''Brotherhood'', likely due to his more sympathetic motivation of [[spoiler: being the failed transmutation of Dante and Hohenheim's son, and resenting his father and half-brothers]]. But it's to the point where some fangirls seem to forget that he's so evil; some of them even [[FoeYay ship him with Ed]]!
* EnsembleDarkhorse:
** Many FMA fans seem to really like the anime version of Sloth; some even prefer her to the manga's version, which is quite a feat, since the other two [[CanonForeigner "replacement Homunculi"]], ([[CreepyChild Wrath]] and [[PresidentEvil Pride]]), are major {{Base Breaker}}s. It probably helps that she has [[DarkAndTroubledPast a little more depth]] than Manga!Sloth.
** Lust's expanded role and backstory in this version [[spoiler: and eventual HeelFaceTurn]] made her far popular in the 2003 fanbase.
* EvilIsSexy:
** Lust.
** Envy seems to [[LauncherOfAThousandShips get around pretty well]] in fanfiction for one of the most unambiguously evil characters in the series.
* FanonDiscontinuity: "''Conqueror of Shamballa'' never happened" is one of the most common types of FMA FixFic. At the very least, fandom likes to disregard or work around its ending (which [[spoiler: traps Ed and Al forever in our world]], a universe away from nearly all of the people they're shipped with in fanfiction).
* FoeYay: [[spoiler:Because Greed is the incarnation of one of Dante's lovers, he involuntarily feels affection towards her and is drawn to her home, despite the horrible things she does to him.]]
* HilariousInHindsight:
** In episode 22, Envy asks Ed if he wants him to turn into a taller version of Ed. Then comes episode 50 [[spoiler: and we find out Envy was Hohenheim's first son and looks a lot like a taller version of Ed]].
** [[spoiler: Selim Bradley. A human boy in the first anime and King Bradley (Pride)'s adoptive son. Bradley kills him in a fit of rage in the finale.]] In the manga and ''Brotherhood'', [[spoiler: Selim turns out to be Pride (Bradley is the manga's Wrath), oldest and deadliest of the Homunculi, and Bradley works for ''him''.]]
** In one of the flashbacks, a young Ling Yao can be seen, wearing sunglasses similar to Greed; while he has no important role in ''this'' anime, [[spoiler: he becomes the new Greed in ''Brotherhood'' and the manga]].
** At the end of the (non-canonical) OVA "Kids", there is a prominently displayed photograph of an elderly Ed shaking hands with an important-looking, formally dressed man who bears a moderate resemblance to UsefulNotes/BarackObama. (The OVA was made more than three years before he was elected President of the United States.)
* IncestSubtext: There's significantly more of this in this version than in the manga/''Brotherhood'', which is a large part of the reason that [[BrotherSisterIncest Ed/Al]] is as popular of a ship as it is (probably the second most popular slash pairing after Roy/Ed).
* ItWasHisSled: The twist [[spoiler:that behind the Gate is "our world"]] has long since stopped being a spoiler, expected as the series is a major GatewaySeries and one of the most popular anime (especially shonen anime) of the New Millennium. TheMovie only made it less of a spoiler.
* JerkassWoobie: Wrath and Scar
* LauncherOfAThousandShips: Envy was a big one for this series, despite being even more evil here. Ed in particular is even ''more'' of a "fandom bicycle" among the 03 fans, since he never got a canonical love interest in this version.
* MemeticMutation:
** Roy Mustang [[http://www.youtube.com/watch?v=i-RUSFq16Wo&feature=related loves dogs.]]
** Roy Mustang has a dream once he becomes Fuhrer. It involves female officers and [[http://www.youtube.com/watch?v=_WKPH_8PwFA tiny miniskirts]].
* MemeticSexGod:
** Everyone wants [[EvilIsSexy Lust]], no exceptions. Sloth also fares well in this department.
** It's a joke among some fans of this anime that [[LauncherOfAThousandShips everyone]] (yes, ''[[EvenTheGuysWantHim everyone]]'') is in love with Ed and he just [[ObliviousToLove can't see it]].
** Envy, of all characters, seems to be this among certain parts of the fanbase.
* MoralEventHorizon: Crossed by both Scar and the Homunculi. Envy crosses it with [[spoiler:the murder of Hughes]] and enjoys dancing over it again and again. Depending on who you ask, [[spoiler: Bradley]]'s came with either [[spoiler: Marta or Selim's murder]], or TheReveal that [[spoiler: he engineered the Ishvalan War to try to make a Philosopher's Stone, and wants Lior to be a repeat of Ishval]].
* {{Narm}}: [[spoiler:Scar standing up to an absurd amount of punishment in his swan song episode, until it starts to feel like Monty Python. Plus he apparently carries Kimblee's body to a rooftop in his teeth.]]
** [[spoiler:Cyborg Archer. The design is ridiculous, and it stretches SchizoTech to the absolute breaking point.]]
** [[spoiler: Dietlinde Eckhart's convoluted MotiveRant at the end of Conqueror of Shamballa might count]]
* NarmCharm: How many fans feel about [[spoiler:[[FanNickname TerminArcher]]]]
* NoYay:
** [[spoiler: Dante]] hitting on [[FreudWasRight Ed]]. It gets even worse when you consider that she's mainly doing it to "be loved by the son of Hohenheim."
** There's also a bit of [[spoiler: LesYay between Dante, in Lyra's body, and Rose]]...which [[GirlOnGirlIsHot wouldn't have been that bad]], were it not for the fact that [[spoiler: Lyra's body [[{{Squick}} was rotting]] and she wants to take Rose as her next one]].
** And then there's the fangirls who ship Kimblee with [[SociopathicSoldier Archer]]. As if the fact that they're both psychopaths wasn't bad enough, one of them is a ''half-mechanical {{cyborg}}''!
** The episode with Psiren, where she repeatedly unzips her outfit in front of Ed, and makes some decidedly seductive remarks? At this time, Ed is 15 years old.
** The tendency of Envy to be a LauncherOfAThousandShips among some parts of the fanbase, tends to have this reaction among the rest.
* RewatchBonus:
** Everything [[spoiler: "Lyra"]] does after Greed comes to Dante's mansion.
** The twist about where the Gate leads is actually pretty well foreshadowed if you pay attention to some seemingly superfluous details (like the visions Ed recalls from when he was in the Gate, or music characters are humming/whistling). It's way easier to pick up on re-watch after you know that twist.
* TheScrappy: Noah from TheMovie. It turns out it's a pretty good thing the writers didn't create the Ed-Noah-Alfons love triangle originally planned for the film; hardly any fans like her, and instead they ship [[HoYay Ed and Alfons]] together.
* {{Squick}}: The scene where Izumi Curtis eats that crumb off of the the island boy's face was done in a manner that suggested it was supposed to come off as sweet, but it ended up more gross than anything.
* StoicWoobie: Lust. Mustang can give off this impression sometimes, considering his guilt over his part in the Ishvalan war.
* StrawmanHasAPoint / HannibalHasAPoint: The lecture [[spoiler: Dante]] gives Ed and Al about how EquivalentExchange (in terms of being a principle for life, outside of its use in alchemy) is crap. The fact is that, yeah, she's right that there are a lot of times in life where the effort you put into something is disproportionate to what you get out of it (for example, she talks about how Ed, as a ChildProdigy, passed the State Alchemist exam with flying colors on his first try, while others had been slaving away and repeatedly failing it for years). [[spoiler: Hohenheim]] later gives Ed a more optimistic take on it.
* SuperlativeDubbing: Formal reviews of the series rarely pass up mentioning the overall quality of the voicework in the English version. It helps that all of the actors involved ''loved'' the series to death and put their hearts into it.
* TheyChangedItNowItSucks: It's notable that many (though certainly not all) of the complaints about the series come from fans of the manga, rather than from fans who saw it as a stand-alone series. Conversely, it's not unheard of for those exposed to the franchise through the 2003 anime to sometimes have this attitude towards Brotherhood.
* UnintentionallyUnsympathetic: Psiren. Meant to be a {{Classy Cat Burglar}} with sympathetic motives for her crimes...except each and every time those motives are shown to be lies, and she even tries to murder Ed. Her motivation for wanting to give the town visibility (and even then, it's ambiguous whether she actually cares about that) is kind of drowned out by that.
* ValuesDissonance: Izumi's domestic violence against the Elric brothers; Ed and Al abusing each other.
* ViewerGenderConfusion: Envy. Although, unlike in the manga/''Brotherhood'', [[spoiler: he does get a canonical gender at the end]].
* VillainDecay: Envy was pretty much reduced to a plot device in ''Conqueror of Shamballa.''
* {{Wangst}}: Some people find it excessive the way this version handled Al's identity crisis after his confrontation with Barry the Chopper. In the manga and ''Brotherhood'' anime, Winry gives him a stern talking-to and he quickly snaps out of it. Here, he gets an additional episode to stew over it and even when he comes to his senses, it has lingering effects on his later CharacterDevelopment.
* WhatAnIdiot: Both involving homunculi and their deaths:
** Wrath [[spoiler:takes Ed's sample of Mrs. Elric's remains into himself to deny Ed using them on Sloth. Wrath fuses with Sloth. Ed and Sloth figure out what is very stupid about this immediately.]] Sloth even lampshades it!
-->'''Sloth:''' Wrath...you ''fool''...
** Pride when [[spoiler: he strangles Selim for bringing in his AchillesHeel - giving Mustang the chance to use it against him - rather than telling Selim to run away with it]]. The fact that he [[spoiler: had it in his house and trusted Selim with the key to the safe holding it without any knowledge that it could kill him]] is full-on BondVillainStupidity.
** Rose in the 2003 anime had a lot of those moments. A priest says he can bring her BF back to life. She believes him. She later sees the disturbing, horrid, disgusting body that was clearly made out of parrots (who had all their feathers plucked out) that's going to be used to make a replacement for her dead boyfriend and she's ''still'' on the fence about it.
** Al has two of these in the final third, like [[spoiler:stopping Martel from killing Kimblee, thus making him responsible for everything Kimblee does afterward, holding on to the idea that Sloth is his mother long after it's clear that she's trying to kill both him and Ed. To be fair on the second one though, even though he knows it's not his mother, Sloth still looks and has memories of her. She even acts like her to toy with the Elric brothers and it happens to work far better on Alphonse.]] Another instance was in ''Conqueror of Shamballa.'' Why didn't he just [[spoiler: transfer his soul into a suit of armor again and seal the gate on the other side]]? It's not like there weren't any lying around. It would have seriously saved the Elric Brothers [[spoiler: the trouble of having to leave their loved ones behind]].
* TheWoobie: The Elric brothers, many times. Wrath, Winry, Rose, Roy, [[IronWoobie Izumi]], even JerkassWoobie [[AntiVillain Scar]] and StoicWoobie [[HighHeelFaceTurn Lust]].
* {{Woolseyism}}: In the episode with "Warehouse Thirteen", one of the characters mentions that the house only appears at night, and that it's a "Were-house". The pun works ''brilliantly'' in English.
