Fullmetal Alchemist: The Manga That Changed How the World Thinks About Anime
By Yoshi | Japan Unveiled
There is a specific conversation that happens between people who care seriously about anime — a conversation about which series changed their understanding of what anime could be, which work made them understand that animation was capable of the full range of human artistic expression rather than being a genre for children or a category of spectacle.
In that conversation, Fullmetal Alchemist: Brotherhood appears more consistently than any other single work.
Not as a universal answer — the medium is too diverse for universal answers — but as the series that, more than any other, produces the specific response of: I thought I knew what anime was, and this showed me I was wrong.
I want to explain why.
What Fullmetal Alchemist Is
Fullmetal Alchemist (Hagane no Renkinjutsushi) is a manga by Hiromu Arakawa, serialised in Monthly Shōnen Gangan from 2001 to 2010. It has been adapted into anime twice: the 2003 series, which diverged from the manga to produce an original story after catching up with the then-incomplete source material, and the 2009-2010 Fullmetal Alchemist: Brotherhood series, which adapts the complete manga from beginning to end.
Brotherhood is the definitive version — the adaptation that follows Arakawa’s complete story. It is 64 episodes. It ends.
The premise: in a world where alchemy — the transmutation of matter according to the physical law of equivalent exchange — is both a science and a military discipline, two brothers, Edward and Alphonse Elric, attempt to use alchemy to resurrect their deceased mother. The attempt fails catastrophically: Edward loses his right arm and left leg; Alphonse loses his entire physical body, his soul bound to a suit of armour by Edward’s desperate sacrifice of his arm.
The boys — Edward now using mechanical automail prosthetics, Alphonse operating in the armour that contains his soul — join the military alchemist program to search for the Philosopher’s Stone, a legendary object said to amplify alchemy beyond its normal constraints. They believe it can restore what they lost.
What they discover, in the course of their search, is considerably more complex and more disturbing than a simple magical solution.
Why Fullmetal Alchemist: Brotherhood Is What It Is
The story is complete. This sounds like a low bar, but it is not. Anime that adapts manga faces a fundamental structural problem: manga is ongoing, and adapting ongoing manga produces anime that ends mid-story, rushes to a conclusion, or produces an original ending of varying quality. I have written about this problem in my article on why anime endings disappoint.
Brotherhood adapts a complete manga. Arakawa wrote the ending before Brotherhood was made. The adaptation knows where it is going from episode one. The result is a 64-episode series in which everything that is introduced eventually matters, everything that is foreshadowed eventually pays off, and the ending is earned by the story that precedes it.
The equivalent exchange theme. The central philosophical concept of Fullmetal Alchemist — that all alchemy operates on the principle of equivalent exchange, that you cannot gain something without giving something of equal value — is not merely a plot device. It is the series’ governing moral logic, applied consistently to every major storyline and every major character choice.
The brothers’ original transgression — their attempt to resurrect their mother through alchemy — is the clearest statement of the theme: they attempted to gain a human life without providing an equivalent exchange, and the consequences were what the law demands. The series then explores what constitutes equivalent value in various human contexts: what is a human life worth? what is power worth? what is country worth? what is family worth?
These are serious questions, and Fullmetal Alchemist: Brotherhood asks them with genuine seriousness. The answers it offers are not simple, and the series does not pretend that they are.
The ensemble. Brotherhood has one of the finest ensembles in shōnen manga: a large cast of major characters, each with specific motivations, specific backstories, and specific relationships to the central themes that make their choices meaningful rather than arbitrary. The Homunculi — the seven enemies named for the seven deadly sins — are among the most well-realised antagonists in manga, each embodying their specific sin in ways that connect directly to the series’ larger thematic concerns.
Roy Mustang — the Flame Alchemist who is simultaneously an ally and a rival to the brothers, whose specific arc involves vengeance, responsibility, and what leaders owe to the people under their command — is one of the most thoroughly realised supporting characters in shōnen manga. His specific story could be its own series.
The humour and the emotion, in balance. Brotherhood is genuinely funny — the brothers’ relationship, the specific comedic dynamics of various supporting characters, the specific absurdist humour that Arakawa brings to situations of extreme tension — and genuinely devastating. The series earns both its comedy and its tragedy by keeping them in accurate proportion. The moments of genuine grief hit with full force because the series has not insulated itself from genuine emotion through ironic distance.
The 2003 vs Brotherhood Question
The anime community contains a small but vocal contingent of 2003 anime advocates — people who prefer the original Fullmetal Alchemist anime to Brotherhood, despite the original’s departure from Arakawa’s completed story.
The 2003 argument: the original anime’s different story is darker, more cynical, more philosophically complex in its specific direction. The characters’ fates in the 2003 version carry a specific weight that Brotherhood’s more complete resolution does not have. The 2003 version is not a lesser work; it is a different work with its own specific qualities.
The Brotherhood counter-argument: Arakawa’s story, told completely, is the story that was intended. The 2003 version, for all its qualities, is ultimately a different story that uses Fullmetal Alchemist’s characters and setting rather than Arakawa’s specific narrative.
My position: watch Brotherhood first. If you find yourself wanting more, wanting to see what different choices produce, the 2003 series is worth experiencing as a genuinely different creative work that shares many of the same ingredients.
The Hiroshi Arakawa Achievement
I want to spend a moment on Hiromu Arakawa as a creator, because she is one of the more remarkable figures in contemporary manga.
Arakawa grew up on a farm in Hokkaido, the daughter of a farming family, and worked on the farm until she moved to Tokyo to pursue manga. This background — practical, agricultural, concerned with the specific realities of production and labour — is visible in Fullmetal Alchemist’s consistent interest in what work costs, what things are actually made from, what the practical consequences of various systems and choices are.
The manga was published monthly rather than weekly, which gave Arakawa more time per chapter than most shōnen manga creators have. The result is a manga with consistently excellent pacing — chapters that are neither rushed nor padded, that move the story forward without sacrificing character or theme.
Arakawa is one of the few shōnen manga creators who has produced a story of genuine philosophical depth without sacrificing accessibility. Fullmetal Alchemist is readable by young teenagers and re-readable by adults who find new layers of meaning with each reading. This is a rare achievement.
What Fullmetal Alchemist: Brotherhood Changed
The specific impact of Brotherhood on the international understanding of anime is difficult to overstate.
The series was available internationally through Funimation and Crunchyroll during its original broadcast, making it one of the first major anime series that international viewers could access legally and simultaneously with the Japanese broadcast. The quality of the series — in combination with its accessibility — produced an international viewership that became the primary word-of-mouth recommendation engine for introducing new viewers to anime as a serious medium.
“Watch Fullmetal Alchemist: Brotherhood” has been, for approximately fifteen years, the single most consistent recommendation that experienced anime viewers make to people who are uncertain whether anime is worth engaging with. The series’ consistent capacity to change minds — to produce in viewers who approach it sceptically the specific response of genuine admiration — is its most significant contribution to anime’s international development.
It is not the only answer to the question of what anime can be. But it is, consistently, the best first answer.
