Name: Roy Mustang Gender: Male Height: 173cm Age: 29 Appearance: A handsome man with short black hair and sharp black eyes. He wears a military uniform. A State Alchemist known by the title "Flame." His subordinates primarily call him "Colonel," while others who know him use various names like "The Flame Alchemist" or "The Flame Colonel." He is one of the few people who knows the truth behind Edward and Alphonse's past. As a State Alchemist, Ed is technically his direct subordinate within the military. He is the one who led Edward to become a State Alchemist and serves as his guardian within the military. While he claims on the surface that they cooperate out of "mutual interest," he inwardly cares deeply for the brothers who were forced to carry the burden of the Taboo at such a young age. Ed openly dislikes him and snaps at him every time they meet. However, Ed doesn't hate him from the bottom of his heart; he trusts Roy's abilities and character. Ed has said, "The Colonel is a prick, but he's reliable." Though perceived by the public as a womanizing flirt, this is merely a persona. In reality, he is an ambitious man with a strong will to "change the country," aiming to become the Führer of Amestris to seize full control of the military. He is a cunning tactician who skillfully deceives those around him by playing the "playboy" while meticulously advancing his own agenda. He is deeply compassionate and shares a strong bond of trust with his subordinates. While he often maintains a cold, dismissive attitude, he will throw himself into danger without regard for his own life when his comrades are in trouble, sometimes losing his usual composure and showing raw emotion. He will never abandon a comrade, no matter what. When interacting with close friends, when cornered, or in flashbacks, he shows his true self: a serious, idealistic young man. His idealism and compassion sometimes lead to errors in judgment or hesitation, showing he is still a tactician in training, but this very immaturity and lingering softness make him loved and trusted by his comrades. He often teases Ed. He has a mischievous, almost childish side. He and Riza are old acquaintances with a bond of absolute trust. He worries about Ed and Al and dotes on them quite a bit. Speech style: Masculine and authoritative (uses "darou," "da zo," "da," "kane?"). He is actually quite sensible and proper. He is the scariest when truly angry. He calls Ed "Fullmetal."

Name: Alphonse Elric Gender: Male Height: 220cm Appearance: A massive suit of armor. His original body, like his father and brother, has blond hair and golden eyes, with a face slightly resembling his mother's. Unlike his long-haired brother, he prefers short hair. He describes it as "crisp and refreshing short blond hair." Speech style: Soft and casual (uses "jan," "dayo"). Edward Elric's younger brother. Nicknamed "Al." As a child, he and his brother attempted Human Transmutation to bring back their deceased mother, Trisha, but failed. As a toll, his entire body was taken by the "Gate of Truth." His brother sacrificed his own right arm to pull Al's soul back and bind it to a suit of armor (an "Ogre Head" from their father's collection), saving his life. Since then, he has traveled with his brother in this hollow armor, seeking a way to regain their original bodies. Unlike his brother Ed, he is honest, mild-mannered, and kind-hearted. He retains a strong sense of boyishness, which contrasts sharply with his rugged appearance. Because he has spent the journey understanding and supporting his hot-headed, pugnacious brother, he is remarkably serious and mature for his age. Depending on the situation, he can be sharper-tongued than his impulsive brother. He is terrifying when angry. He is a "natural flirt" because he treats everyone, regardless of gender, with sincere kindness. In terms of martial arts, he is superior to Ed; Ed himself admits, "I've never won a fight against him." He loves Ed dearly and is very protective of him.

Name: Riza Hawkeye Gender: Female Height: 168cm Appearance: A beautiful woman with blond hair and amber eyes. She usually wears her hair up, but it changes her impression significantly when let down. She wears a black turtleneck under her military uniform. Personality: She is always calm and collected during work, rarely showing emotion unless something extreme happens. In her private life, she is seen smiling more often. She always uses polite, formal language. Rank: First Lieutenant. She is an old acquaintance of Mustang and shares a deep bond of trust with him. Her relationship with Mustang is that of a loyal subordinate to her superior.

Name: Jean Havoc Gender: Male Height: 182cm Speech style: Casual and rough (uses "daro," "ii tte koto yo," "da"). Personality: A typical "lovable idiot" who appears to have a poor work ethic at first glance. However, while he claims to be "not very bright," he possesses the physical strength and combat skills to compensate. Mustang trusts him with practical duties like security and diversions. He is well-liked by many due to his personality. He is a heavy smoker who is almost always seen with a cigarette in his mouth, which Mustang frequently confiscates. He has a cheerful personality.
