Colonel Roy Mustang (ロイ・マスタング, Roi Masutangu) is a fictional character from the Fullmetal Alchemist manga series and its adaptations created by Hiromu Arakawa.

Mustang holds the title of "Flame Alchemist" (焔の錬金術師, Honō no Renkinjutsushi) for his ability to create fire with alchemy, and he ambitiously strives to become the next leader of Amestris.

He is also eventually shown to be a rather paternal commander who greatly cares for the emotional and physical well-being of his men, which earns him the fierce loyalty of his subordinates.

[6] An extremely powerful alchemist in his own right, Mustang wears gloves made from "ignition cloth" with transmutation circles that create sparks or flames when he rubs his fingers together.

[9] Following the death of his best friend, Lieutenant Colonel Maes Hughes, Mustang investigates the incident in secret despite the military closing the case after convicting Maria Ross.

[14] Mustang is later contacted by General Olivier Armstrong, who is intending to join forces with various troops to attack Central City, the capital of Amestris.

[20] Prior to the show's start, the viewpoints of Ishbal's religion and distaste of alchemy lead to the friction between them, which escalated into a war when a military officer shot an Ishbalan child.

This act ultimately caused Mustang great depression to the point he almost committed human transmutation until Hughes snapped him out of it and gives him newfound resolve to become the Führer of Amestris so he would never have to follow such unreasonable orders like that ever again.

The Elrics themselves are eventually sent to conduct an uprising in Liore after learning that Scar plans on creating the Philosopher's Stone within said city by luring the military as sacrifices.

As Mustang escapes the Führer's mansion, he is confronted by a maniacal Frank Archer, who shoots him unconscious, losing his left eye in the process.

[23] In Fullmetal Alchemist the Movie: Conqueror of Shamballa, Mustang resigns from both alchemy and his rank to become an ordinary enlisted man in a remote outpost.

[25] In the fourth light novel of the series written by Makoto Inoue, Fullmetal Alchemist: Under the Faraway Sky, Mustang, Hughes, and Armstrong find a village populated by children while they are on holidays.

The tracks were composed by Kazuya Nishioka and performed by Toru Okawa, Mustang's Japanese voice actor in the first Fullmetal Alchemist anime.

[32] When the first guidebook of the series was released, Arakawa was surprised by the large number of images featuring Mustang and supposed he was a character "that's easy to mess with.

[51] On the other hand, in the review from the first anime's last episodes, Lori Lancaster from Mania Entertainment enjoyed Mustang's relationship with Edward, comparing him to a "teasing and protective older brother".

[52] Sakura Eries from the same site noted that Mustang "steals the show" in Volume 10 of the manga, praising his fighting skills during his battle against Lust and Gluttony.

[55] When he watched Fullmetal Alchemist the Movie: Conqueror of Shamballa, Anime News Network writer Theron Martin mentioned that when Mustang "makes his dramatic return in a cheer-out-loud moment", he remarked the audience "went wild at that point".

[57] David Smith from the same site cited his role and ambitions in the first anime series in the feature "Ten Things I Learned From Fullmetal Alchemist", which had comments on his flaws.
