Few anime franchises spark as much debate over watch order as Fullmetal Alchemist. Two distinct television adaptations, a feature film sequel to the first, a side-story movie set in the second timeline, and a handful of OVAs all orbit Hiromu Arakawa’s acclaimed manga. The result is a viewing puzzle that can intimidate newcomers and divide veteran fans. This guide untangles every thread—comparing the 2003 series and Brotherhood, explaining how the movies fit, and laying out multiple watch orders so you can choose the experience that best suits your tastes.

Why Are There Two Fullmetal Alchemist Series?

The original Fullmetal Alchemist anime began airing in October 2003 while Arakawa’s manga was still in its early stages. Studio Bones produced 51 episodes that adhered to the manga’s early arcs but gradually invented an original second half, complete with new antagonists, a radically different origin for the homunculi, and a conclusion that closes the Elric brothers’ story in a way the manga never intended. Because the anime had to outpace the source material, it built its own mythology, leaning heavily into psychological drama and an alternate-history Europe setting.

Fullmetal Alchemist: Brotherhood arrived in April 2009, a few months after the manga finished its nine-year run. With the complete story available, Bones was able to craft a 64-episode adaptation that remains remarkably faithful to Arakawa’s vision. Brotherhood is widely regarded as the definitive adaptation for those who want the full, unaltered narrative—one that weaves together political intrigue, philosophical questions about sacrifice, and a sprawling cast whose arcs culminate in a climactic final battle. Both series stand on their own as monumental achievements, but they provide fundamentally different journeys.

Core Differences Between the Two Adaptations

While both series begin with the Elric brothers’ tragic attempt to resurrect their mother and their search for the Philosopher’s Stone, the storytelling diverges sharply after roughly episode 15 of the 2003 series. Understanding these differences will help you decide your watch order.

Story and Ending

The 2003 anime crafts a more insular, emotionally charged tale. The homunculi are not created the way they are in the manga; they are the product of failed human transmutation, which ties them directly to individual alchemists’ guilt. The series ends with an emotionally complex, bittersweet finale that sends the brothers to separate worlds. The follow-up film, Fullmetal Alchemist: The Conqueror of Shamballa, provides closure for this timeline.

Brotherhood, by contrast, expands the scope enormously. The homunculi are artificial humans created by the primary antagonist, Father, and the narrative evolves into a nationwide conspiracy to sacrifice the entire population of Amestris. The series concludes with a grand-scale showdown and a more hopeful, satisfying resolution that honors the core theme of equivalent exchange. Character arcs for Roy Mustang, Riza Hawkeye, Scar, and the Xingese visitors are far more developed.

Pacing and Tone

The original 2003 series spends its first 25 episodes building a slower, more atmospheric foundation, giving weight to the brothers’ childhood, their training with Izumi Curtis, and the moral ambiguity of state alchemists. Brotherhood’s early episodes cover similar ground but at a faster clip, assuming some viewers may already know the basics. Where the 2003 series leans into melancholy and horror-tinged drama, Brotherhood balances dark moments with sharp humor, grand action set-pieces, and an ultimately uplifting register.

Character Depth

Brotherhood offers a richer ensemble piece. Characters like Ling Yao, Lan Fan, May Chang, Olivier Mira Armstrong, and Solf J. Kimblee receive substantial screen time and complex motivations. The 2003 series, operating with fewer episodes, focuses most of its emotional weight on Edward and Alphonse Elric, though it does give memorable original characters like the alchemist Dante a place in the spotlight. Your preference for tight character drama versus sprawling epic will influence which adaptation resonates more.

The Complete Fullmetal Alchemist Anime Library

Watch Order Options

There is no single “correct” watch order, but three primary paths have emerged among fans and critics. Each offers a distinct experience.

Option 1: The Classic Original Experience

If you want to see the series the way early fans did and appreciate the creative risks of an anime-original story, start with the 2003 adaptation.

  1. Fullmetal Alchemist (2003) – All 51 episodes.
  2. Fullmetal Alchemist: The Conqueror of Shamballa – The movie caps off the story. Watch it immediately after the final episode.

This order delivers a complete, self-contained narrative. You will fall in love with Ed and Al through deliberately paced character development and then experience a closure that, while unconventional, has moved audiences for two decades. After finishing, you can approach Brotherhood with fresh eyes, ready to see how the full manga story unfolds.

Option 2: The Manga-Faithful Route (Brotherhood First)

For most newcomers today, the recommended starting point is Brotherhood. It requires no prior knowledge, presents the story exactly as Hiromu Arakawa wrote it, and has the benefit of modern animation and a sweeping orchestral score. Its pacing and humor align more closely with contemporary shonen sensibilities.

  1. Fullmetal Alchemist: Brotherhood – All 64 episodes.
  2. Fullmetal Alchemist: The Sacred Star of Milos – An entertaining side story that fits loosely after episode 20 or so (though it can be watched any time after the early Brotherhood arcs without spoiling the main plot).
  3. Brotherhood OVAs – Optional but rewarding; they deepen backstories for Izumi, Roy Mustang, and others.

If you choose this path, you can later explore the 2003 series and Conqueror of Shamballa as an “alternate universe” take, similar to how many franchises explore “what if” scenarios.

Option 3: The Hybrid Chronological Order

Some fans passionately recommend a hybrid viewing that capitalizes on the slower, more detailed early episodes of the 2003 series before switching to Brotherhood for the manga-accurate second half. This method acknowledges that Brotherhood’s opening episodes compress a lot of material. The hybrid order goes like this:

  1. Watch Fullmetal Alchemist (2003) episodes 1–25.
  2. Watch Fullmetal Alchemist: Brotherhood from episode 1 (or episode 4, depending on the guide) to the end.

This approach ensures you get the emotional weight of the brothers’ origin, the Nina Tucker tragedy, and other early moments told with greater breathing room. However, it requires a pivot between two series with different continuity, and some minor inconsistencies will appear (homunculus creation rules, side character appearances). If you are a stickler for tonal consistency, the pure Brotherhood route is safer. But if you treasure slow-burn storytelling, the hybrid order can be deeply rewarding. After finishing Brotherhood, you can return to the 2003 series’ original second half (episodes 26–51) and Conqueror of Shamballa to experience its uniquely dark conclusion.

Placing the Movies Correctly

Movie placement can trip up even seasoned fans, so let’s clarify exactly where each film belongs.

Fullmetal Alchemist: The Conqueror of Shamballa

This is a direct sequel to the 2003 series. It takes place two years after the anime’s finale and is essential viewing if you invest in the original timeline. Do not watch it before finishing the 2003 show, as it contains massive spoilers and relies entirely on the series’ unique ending. While the film’s historical setting (Weimar-era Germany) may feel jarring at first, it resolves Edward’s arc and delivers a poignant farewell to the characters you followed for 51 episodes.

Fullmetal Alchemist: The Sacred Star of Milos

Set within the Brotherhood continuity, this film is a standalone adventure featuring the Elric brothers. The story takes place before the final arc of Brotherhood, roughly around the time the brothers visit Fort Briggs. You can watch it any time after episode 20 of Brotherhood, but many fans suggest saving it until after you finish the series to avoid any risk of incidental spoilers or pacing disruption. It’s a visually distinct side story with a heavier focus on Julia Crichton and the people of Milos. While not required to understand the main plot, it offers a pleasant bonus mission with spectacular alchemy animation.

Streaming Availability and Official Resources

As of now, both series are readily available on major streaming platforms. You can watch Fullmetal Alchemist: Brotherhood on services like Crunchyroll and Funimation. The 2003 series is also available for streaming on Crunchyroll in select regions. For the most up-to-date information on licensing, checking AniList or MyAnimeList entries can be helpful. The official English-language manga, published by VIZ Media, is another excellent resource for those who want to compare the source material directly. While reading the manga is not required to enjoy the anime, it adds a layer of appreciation for Brotherhood’s fidelity.

Making the Choice: Which Order Is Right for You?

Your ideal watch order depends on what you value most in a storytelling experience. Use these questions to guide your decision.

  • Do you want the complete, unaltered story as the author intended? Go with Brotherhood first. It is the definitive adaptation and leaves no loose threads.
  • Do you prefer a slower, more emotional build-up and don’t mind an anime-original ending? Start with the 2003 series and its movie. It is a masterclass in character-driven drama.
  • Are you fascinated by seeing how the same premise can spawn two distinct masterpieces? Watch both, in either order. Many fans argue that experiencing the 2003 version first makes Brotherhood’s revelations more impactful because you have already formed a bond with the characters. Others feel Brotherhood should be the foundation, then you can appreciate the 2003 series as an inventive reinterpretation.
  • Worried about missing nuance in Brotherhood’s early episodes? Consider the hybrid order, but be prepared for a slight tonal shift when you switch series.

Common Myths and Questions

Let’s address some of the most frequent points of confusion surrounding the franchise.

“Brotherhood is just a remake, so I can skip the 2003 series.”
Not exactly. Brotherhood is not a remake; it is a readaptation of the same source material with a completely different second half. The 2003 series tells its own story and explores themes Brotherhood never touches. Both are worth watching.
“The Conqueror of Shamballa is confusing if I haven’t seen the 2003 series.”
Very true. The film assumes you have seen the original’s finale. If you watch it cold, you will be lost. Always complete the 2003 series first.
“Brotherhood has filler episodes I should skip.”
Unlike many long-running shonen, Brotherhood has almost no filler. Every episode advances plot or character. The only truly optional content is the OVA collection, which is supplementary. Do not skip any episodes of the main series.
“The Sacred Star of Milos is essential to understand Brotherhood.”
It is not. The film is a side story that does not affect the main plot. You can safely skip it, though it does feature some impressive animation and world-building around the nation of Creta.

Deepening Your Experience: Manga and Soundtracks

If the anime leaves you craving more, the original manga by Hiromu Arakawa is a logical next step. Its crisp artwork, bonus four-panel comics, and additional character details make it a joy to read even after you know the story. The VIZ Media official page provides information on the complete box set. The soundtracks for both series, composed by Michiru Oshima (2003) and Akira Senju (Brotherhood), are also exceptional standalone experiences. Senju’s orchestral score for Brotherhood, in particular, is frequently cited as one of the best in anime.

Final Recommendations and a Sample Viewing Marathon

If you are still undecided, here is a plug-and-play marathon plan that gives you the best of both worlds without overwhelming you:

  1. Watch Fullmetal Alchemist (2003) episodes 1–25. These episodes cover the introductory material with tremendous care.
  2. Pause and decide: if you are emotionally invested and want to see where this specific story goes, continue with episodes 26–51 and then watch The Conqueror of Shamballa. Later, you can circle back to Brotherhood.
  3. If after episode 25 you’d rather commit to the full manga story, switch to Fullmetal Alchemist: Brotherhood from episode 1 (or episode 6 to skip some overlap) and watch all 64 episodes. Follow it with the OVAs and The Sacred Star of Milos if desired.
  4. Eventually watch the other adaptation anyway. The franchise rewards revisiting.

Fullmetal Alchemist endures because it asks profound questions about sacrifice, humanity, and the cost of power. Whichever path you choose, the journey is unforgettable. The Elric brothers’ promise to restore their bodies will echo long after the credits roll, whether you travel with them through the dimly lit streets of 2003’s alternative Europe or across the vast battlefields of Brotherhood’s Amestris.
