Fullmetal Alchemist: A Starter Guide
If you caught it on Cartoon Network’s Adult Swim, you know why it’s an all‑timer. The 2003 series premiered in the U.S. on Nov 6, 2004; Fullmetal Alchemist: Brotherhood aired in English from Feb 2010 to Sept 2011. (Wikipedia)

Which version should you watch?
Brotherhood (2009) is the manga‑faithful adaptation and the usual “start here” pick. Fullmetal Alchemist (2003) begins similarly but branches into an original second half; many fans watch it second for its moodier, alternate ending.


Why Edward & Alphonse learned alchemy
After their mother Trisha dies, the Elrics study alchemy (later training under Izumi Curtis) and commit the ultimate taboo: human transmutation. The attempt fails—Al loses his body, Ed sacrifices an arm and a leg to bind Al’s soul to armor—and their quest to reclaim themselves begins.
The Gate of Truth (the “Portal”)
Those who attempt human transmutation confront Truth before a vast Gate. Passing the Gate extracts a toll—limbs, memories, more—yet imprints forbidden understanding. That’s why Ed can perform transmutations with a clap: he’s internalized what others must draw.


How alchemy works (in‑universe)
Alchemy runs on three steps: understanding → deconstruction → reconstruction, governed by Equivalent Exchange—to obtain, something of equal value must be lost.
Transmutation circles — what they do
- Containment: the outer circle creates a closed system and channels energy flow.
- Instructions: the internal array (polygons, sigils, rings) encodes what can change and how far it can change—an algorithm for matter.
- Varies by task: from quick fixes to nation‑scale arrays, complexity matches ambition.
- Ed’s “clap” trick: after meeting Truth, Ed can shape the array mentally; most alchemists still need the drawn circle.


Equivalent Exchange, the Philosopher’s Stone — and Harry Potter?
Equivalent Exchange is the show’s ground rule: nothing from nothing. The Philosopher’s Stone lets alchemists appear to bypass that rule—because the cost has already been paid in horrific currency (human lives). That moral trap sits at the heart of the story.

Thought experiment: transmuting a ruby
A ruby is aluminum oxide—corundum (Al2O3)—with a trace of chromium that produces the red color. In‑universe, an alchemist would:
- Match materials: provide equivalent inputs (Al + O in a 2:3 ratio) plus trace Cr for color.
- Encode the lattice: draw an array that specifies corundum’s trigonal structure and controlled chromium substitution—so it forms ruby, not colorless sapphire.
- Rebuild precisely: deconstruct to fundamentals, then reconstruct as a single crystal; the better the clarity/size, the higher the energy and precision required.
With a Philosopher’s Stone, you could correct flaws on the fly—but that’s exactly the ethical snare FMA interrogates.


What to expect
- Big ideas + big feelings: family, grief, science ethics, war (the Ishval arc), and found‑family warmth.
- Rule‑based action: alchemy as engineering under pressure—smart fights, not just spectacle.
- A complete story: Brotherhood wraps every thread in 64 episodes; the 2003 series continues into Conqueror of Shamballa.
- Iconography: Ed’s red coat, the winged-serpent Flamel symbol, and unmistakable circles.
