Roy Mustang, is the tritagonist of the Fullmetal Alchemist series. He is a State Alchemist and officer in the Amestrian State Military. A hero of the Ishval Civil War and Edward Elric's superior officer, Colonel Mustang is a remarkably capable commander who plans to become the next Führer of Amestris.
Roy is perceived as a shallow, self-absorbed, and a womanizer among many of his colleagues and subordinates. The latter has effectively increased his unpopularity among the enlisted men, many of whom fear having sweethearts and crushes romanced away from them by his hand. Easily as arrogant as his young protégé, Edward, Colonel Mustang is one to act in an ostentatious manner and appears to act mostly out of self-interest rather than any sort of philanthropy. He often slacks on paperwork and other menial tasks, but is quick to take action when it appears that there is glory and military notoriety to be gained.
However, while these traits do have a place in his real personality, much of his outward persona is a façade intended to mask his ambition, and have those unfamiliar with him underestimate his remarkable intelligence and prowess. Mustang is an exceptional tactician, well-versed in various strains of combat theory and particularly talented in the realms of surreptitious information-gathering, covert operations and enemy ensnarement. Roy is expertly manipulative and prone to think several steps ahead of those around him, giving him a remarkable talent for making subordinates act exactly as he wishes despite appearing not to have had a hand in their decisions - all traits which make the fact that he has managed to attain the lofty rank of colonel at such a young age. He is even shown to use his reputation as a shameless flirt to his advantage, with the manga and 2009 anime showing him use his flirtations as a method of discreetly passing on information, as well as a cover for secret operations.
Inwardly, Mustang harbors a deep ambition to lead the country, allowing no obstacle to hinder him on his path to the top. His own actions in the Ishvalan Civil War have left him with haunting regret and a desire to bring to justice those who committed war crimes, even if this includes himself. Recognizing the corruption and futility stemmed from the war, Mustang seeks to lead the country himself to a better cause.
At the core, he is a remarkably devoted commander with a strong sense of justice. Though he hides it well behind a veil of cynicism and self-importance, Mustang is a man who cares deeply about the people who trust and support him and goes to great lengths to ensure their safety and well-being, even at the risk of his own. As a man with considerable power, Mustang considers himself a protector to those without and acts accordingly, earning the staunch loyalty of his most trusted compatriots.
Unfortunately, his self-imposed position as protector has caused him to display a penchant toward stubbornness in regards to his pride on the field and a fiery temper, both of which have been shown to cloud his judgment in certain situations.
[Flame Alchemy - Even among the elite State Alchemists, Colonel Mustang is a particularly skilled alchemist, well-versed in standard physical transmutation, experimental theory, and biological alchemy. However, the brilliant skill that earned him a state license, national notoriety, and "hero" status during the Ishval Civil War is his extraordinarily powerful fire-based combat style.]
[Charisma: Natural talent for leading a military force. In this case, Roy Mustang specialized in military battle.]
