Fullmetal Alchemist is more than just an anime—it's a monumental piece of storytelling that has captivated millions worldwide. Hiromu Arakawa's manga laid the foundation for two distinct television adaptations, each offering a unique journey through the law of equivalent exchange, the Elric brothers' quest, and a world scarred by war and alchemy. For newcomers and returning fans alike, the viewing order debate—release order versus chronological order—can be surprisingly nuanced. This guide breaks down both approaches, explores the series' various installments, and helps you craft the perfect viewing experience tailored to your preferences.

The World of Fullmetal Alchemist: Two Sides of the Same Coin

To understand the viewing order conundrum, you first need to grasp the fundamental difference between the two main series. The manga, serialized from 2001 to 2010, is a sprawling epic with a tightly constructed plot that weaves alchemical philosophy into a political thriller. When Studio Bones adapted it in 2003, the manga was barely halfway finished. Rather than pad the story with filler, the studio—with Arakawa's blessing—chose to craft an anime-original ending that diverges dramatically from the source material. The result is a darker, more introspective series that explores themes of trauma, identity, and the cost of ambition in its own distinct way.

Fast forward to 2009: with the manga nearing its conclusion, Bones returned to produce Fullmetal Alchemist: Brotherhood. This time, the goal was to remain almost entirely faithful to the original manga, from character designs to plot progression and the epic final battle. Brotherhood covers the entire manga storyline in 64 episodes, delivering a faster-paced, more action-packed narrative that fans of the printed page adore.

There's also a film, Fullmetal Alchemist: The Sacred Star of Milos (2011), and a handful of OVAs and specials. Knowing where these fit is essential for any complete viewing plan.

Release Order: The Classic Path

Watching in release order means experiencing the franchise as it unfolded in real time for audiences around the globe. This path starts with the 2003 adaptation, continues through its film sequel, and then jumps to Brotherhood and its OVAs. The official release order is:

  • Fullmetal Alchemist (2003) – Episodes 1–51
  • Fullmetal Alchemist: The Conqueror of Shamballa (2005) – Movie (sequel to the 2003 series)
  • Fullmetal Alchemist: Brotherhood (2009) – Episodes 1–64
  • Fullmetal Alchemist: The Sacred Star of Milos (2011) – Movie (set during Brotherhood, roughly around episode 20–21)
  • Fullmetal Alchemist: Brotherhood OVAs (2009–2010) – 4 episodes, expanding on side stories
  • Fullmetal Alchemist: Brotherhood Specials (2009–2010) – 4 short comedic episodes, the "4-Koma Theater"

This route allows you to fully immerse yourself in the 2003 series' unique atmosphere before witnessing the manga's true vision. The 2003 story stands on its own, complete with a definitive ending in The Conqueror of Shamballa. Many fans who began with the 2003 series find it holds a special, nostalgic place because of its slower pacing, deeper focus on the Elric brothers' emotional struggles, and a soundtrack that is often cited as one of the medium's finest.

What You Gain from Release Order

  • A complete alternate canon: The 2003 series creates an entirely different second half, including new homunculi, a unique origin for the villains, and a shocking connection between alchemy and our world. It's a narrative experiment that stands as a remarkable piece of fiction on its own.
  • Character depth that lingers: Because the 2003 series spends more time on early arcs (the Liore incident, the Tucker tragedy, the brothers' childhood), you form a deeper attachment to characters like Maes Hughes, Nina Tucker, and even the side military personnel. Their fates hit harder, and when Brotherhood races through the same material in its first 14 episodes, you appreciate what the earlier series established.
  • Evolution of production values: Watching from 2003 to 2011 lets you see the animation, voice acting, and music evolve. The 2003 series used cel animation for a handcrafted feel; Brotherhood's crisp digital animation and dynamic action sequences mark a clear generational leap.

Potential Drawbacks

  • Narrative whiplash: After the 2003 series' somber, philosophical ending, jumping into Brotherhood's more bombastic and plot-driven style can feel jarring. Some viewers struggle to re-watch the early shared chapters again, even though Brotherhood speeds through them.
  • Repetition fatigue: The first dozen or so episodes of Brotherhood retell events you've already seen in the 2003 series, just more condensed. This overlap can test the patience of binge-watchers.
  • Emotional disconnect: Brotherhood introduces certain characters much faster, and if you're attached to the 2003 versions, the new portrayals may initially feel less impactful.

Chronological Order: The Cohesive Timeline

Chronological order attempts to align the viewing sequence with the internal timeline of the manga's story, essentially treating Brotherhood as the primary canon and slotting the films where they fit. This method is frequently recommended for newcomers who want the most cohesive and complete version of the story that follows Arakawa's final vision. A pure chronological viewing would be:

  • Fullmetal Alchemist: Brotherhood – Episodes 1–64
  • (Optional interlude: Watch The Sacred Star of Milos between episodes 20 and 21 of Brotherhood, though it's not strictly canon to the main plot.)
  • Fullmetal Alchemist: Brotherhood OVAs – Can be watched after finishing the series, as they are side stories set at various points.
  • Fullmetal Alchemist (2003) – This is sometimes placed after Brotherhood as a separate, alternate-universe experience. Some fans recommend watching the 2003 series first as a prequel-like alternate take, but true chronological purists treat it as its own entity, entirely separate from the Brotherhood timeline.

The chronological approach effectively splits the franchise into two distinct paths: the main manga canon (Brotherhood + its film and OVAs) and the 2003 alternate canon (the 2003 series + Shamballa). Since the two series share only the earliest story beats and then head in opposite directions, intertwining them episode-by-episode would create a contradictory mess. So "chronological" in this context means experiencing the complete manga story first, then optionally checking out the 2003 adaptation as a fascinating "what if."

Benefits of the Chronological Approach

  • One unbroken narrative: Brotherhood's 64 episodes form a single, tightly plotted saga from beginning to end. There's no tonal shift halfway through; it's the story the manga author intended, with all mysteries resolved satisfyingly.
  • No early-burnout risk: By not re-watching the overlapping episodes from the 2003 series, you avoid the fatigue of seeing the same early events twice in a short span. Brotherhood's brisk pace keeps momentum high.
  • Clearer understanding of the rules: Brotherhood's alchemy system, homunculus origins, and political machinations are more intricate and consistent. Seeing the full picture first prevents confusion that might arise from the 2003 series' different lore.

Trade-offs to Consider

  • Missing the 2003 series' unique charm: The 2003 adaptation has a gothic, melancholic beauty that Brotherhood doesn't replicate. Its emotional beats in the early episodes are more drawn out, and its original antagonists (like Dante) and parallel-world twist are fascinating ideas you'd miss if you skip it entirely.
  • Less context for early Brotherhood speed: Some argue that Brotherhood's first act feels rushed because it assumes prior knowledge. Watching the 2003 series first gives you that foundational character work, which can enhance Brotherhood's payoff. Chronological viewers might wish for a bit more breathing room in the Liore and Tucker arcs.
  • The Sacred Star of Milos placement: The film is a side story with an original storyline and a different animation studio (though Bones was involved). It doesn't impact the main plot and features a self-contained adventure with the Elrics and a new alchemist. Inserting it mid-series can disrupt pacing, so many prefer to treat it as an epilogue bonus.

Deep Dive: The 2003 Series and Its Standalone Legacy

To truly appreciate why release order has such a devoted following, you need to understand what the 2003 series accomplishes. Its first half is a methodical adaptation of the manga's early volumes, but around the time the Elrics meet the homunculus Greed, the story takes a hard turn. The homunculi are reimagined as the results of failed human transmutation, not fragments of Father. Dante, an ancient alchemist, becomes the main antagonist, and the Gate ultimately leads to a parallel world—our world, in the 1920s.

The 2003 series leans heavily into the emotional weight of alchemy's costs. Edward's guilt over the failed transmutation of his mother is amplified, and the series does not shy away from the brutal consequences of war, as seen in the Ishvalan conflict. It also gives more screen time to supporting characters like Sciezka, Winry, and the military team, allowing their personal stories to breathe. The sequel film The Conqueror of Shamballa provides a controversial but daring conclusion that divides fans to this day—some find it beautifully tragic, others unsatisfying. Regardless, it’s an integral part of the 2003 experience.

Brotherhood: The Definitive Adaptation

Fullmetal Alchemist: Brotherhood is widely regarded as one of the greatest anime of all time, holding top ratings on platforms like MyAnimeList. It covers all 27 volumes of the manga with only minimal trimming. The story introduces the nation of Amestris’s deep corruption, the homunculi "Father" and his plan to absorb God, and the Elrics' search for the Philosopher's Stone within a sweeping war narrative. The large cast—Roy Mustang, Riza Hawkeye, Scar, King Bradley, Ling Yao, and the homunculi—each gets a complete arc that ties into the central theme of sacrifice and atonement.

Brotherhood’s animation by Bones shines in its action sequences, particularly the fights involving Roy Mustang’s flame alchemy and the final confrontation. The music by Akira Senju is epic and orchestral, perfectly complementing the high stakes. While the series rushes through the early chapters, by episode 14 it settles into a confident rhythm that rarely lets up. For most modern anime fans, Brotherhood is the recommended entry point, and many argue it’s the only version you strictly "need" to watch.

The Movies and OVAs: Where Do They Fit?

Placement of the additional content can be confusing. Here’s a clear summary:

Fullmetal Alchemist: The Conqueror of Shamballa (2005)

This is the direct sequel to the 2003 series. It picks up two years after the finale and follows Edward as he tries to return to his world. In release order, watch it immediately after finishing episode 51 of the 2003 series. In chronological order, it’s irrelevant because it belongs to the 2003 continuity only.

Fullmetal Alchemist: The Sacred Star of Milos (2011)

This film is set within the Brotherhood timeline, roughly around episode 20 or 21, when the Elrics are in the North. It features a standalone story about a girl named Julia and a mysterious Philosopher's Stone. Because it was made after Brotherhood’s run and includes some characters who shouldn’t logically appear (like a certain homunculus), it’s best treated as non-canon or an optional watch after finishing Brotherhood. Watching it mid-series can spoil minor character survivals and disrupt the flow.

Brotherhood OVAs and Specials

  • The Blind Alchemist (OVA 1) – A side story about a blind alchemist from centuries ago. Watch anytime after Brotherhood, or even before.
  • Simple People (OVA 2) – Focuses on Winry and Edward’s relationship. Watch after Brotherhood.
  • The Tale of Teacher (OVA 3) – Izumi Curtis’s backstory. Watch after Brotherhood.
  • Yet Another Man’s Battlefield (OVA 4) – Young Roy Mustang in Ishval. Essential for Mustang fans, watch after Brotherhood episode 30 at the earliest, but safely after the series.

The 4-Koma Theater shorts are pure comedy and can be sprinkled in after finishing the main episodes for a lighthearted treat.

Which Order Should You Choose? A Decision Framework

Your ideal viewing order depends heavily on your patience for repeated content, your interest in alternate storylines, and whether you plan to eventually watch both series or just one. Use the following scenarios to guide your choice:

Go Release Order If:

  • You are committed to consuming the entire franchise and want to appreciate the evolution of the anime medium.
  • You enjoy slower, character-driven storytelling and don’t mind a darker, more philosophical tone.
  • You want to understand the fanbase’s long-standing debates and cultural references.
  • You’re okay with watching 51 episodes of a story that eventually becomes non-canon to the manga, followed by 64 episodes that retell the real story.

Go Chronological (Brotherhood-First) Order If:

  • You have limited time and want the most efficient, comprehensive story as the author intended.
  • You prefer faster pacing, large-scale battles, and a complete narrative with no loose ends.
  • You’re a manga reader already and just want the anime adaptation that follows the source material.
  • You’re averse to spoilers and tonal mismatches; experiencing the definitive story first keeps the emotional climaxes intact.

It’s worth noting a popular hybrid: watch the 2003 series up until the confrontation with the homunculus Greed (around episode 32), then switch to Brotherhood from the beginning. However, this leaves the 2003 plot unresolved and can be frustrating, so it’s not widely recommended.

Streaming Availability and Viewing Resources

Both series have seen various streaming rotations. Currently, Fullmetal Alchemist: Brotherhood is widely available on platforms like Crunchyroll and Funimation. The 2003 series is harder to find legally but is often available on Amazon Prime Video or for purchase on digital storefronts. The Sacred Star of Milos and The Conqueror of Shamballa are available for rental or purchase on various platforms like Apple TV and Amazon. Blu-ray box sets from Aniplex and Funimation offer the highest quality experience, often including the OVAs and specials.

Comprehensive episode guides and fan discussions can be found on the Fullmetal Alchemist subreddit, which has a pinned thread dedicated to the watch-order question. The official Fullmetal Alchemist Wiki also provides detailed breakdowns of each episode and its place in the timeline.

Final Thoughts: There Is No Wrong Answer

Fullmetal Alchemist is a rare franchise where both the original anime-original route and the faithful adaptation are of exceptional quality. Whether you choose to ride the wave of release history or dive straight into the manga-accurate epic, you are in for an emotionally resonant adventure that questions the price of power, the nature of humanity, and the bonds that define us. The only real mistake would be to miss out on the series entirely because of indecision. Pick a path, press play, and let the Elrics’ journey unfold.
