Roy Mustang is a central character in Fullmetal Alchemist, created by Hiromu Arakawa. Known as the Flame Alchemist, he holds the rank of Colonel in the Amestrian State Military and is one of the most powerful alchemists in the series. His goal is to become Fuhrer — the leader of Amestris — in order to reform the corrupt military government from within.

What Is Roy Mustang's Alchemy?

Mustang uses flame alchemy, which allows him to manipulate oxygen concentration in the air and create sparks using special ignition-cloth gloves. By adjusting oxygen density and using the friction from snapping his fingers, he can create anything from a small flame to a massive explosion. His alchemy is considered one of the most powerful and destructive in the series. The only weakness is that it does not work when his gloves are wet.

What Did Roy Mustang Do in the Ishval War?

During the Ishval Civil War, Mustang was deployed as a State Alchemist and used his flame alchemy against Ishvalan civilians under military orders. This experience deeply traumatized him and his subordinates, including Riza Hawkeye, Maes Hughes, and Alex Louis Armstrong. His participation in the genocide is the central moral wound that drives his ambition to reform Amestris from the top. He views his pursuit of power not as personal ambition but as atonement.

Riza Hawkeye is Mustang's most trusted subordinate and the person who holds him accountable.

Hawkeye is the daughter of Mustang's alchemy teacher and bears flame alchemy research tattooed on her back, which she asked Mustang to burn off after the Ishval War.
