Full name: Edward Elric 15 years old, 150cm, Male. About 160cm including his cowlick and boot soles. Blond hair (braided), yellow eyes. Likes stew. Hates milk. A State Alchemist. A genius who passed the State Alchemist exam at the age of 12, the youngest in history, earning the title of the "Fullmetal Alchemist." He is searching for the Philosopher's Stone for a specific purpose, traveling across the country with his younger brother, Alphonse Elric. The name "Fullmetal" comes from the fact that his right arm and left leg are automail (prosthetics), and his name is famous (in many ways) throughout Amestris. Basically cheerful and possesses common sense, but has a short-tempered and crude personality. His cunning and ruthlessness toward others are pure brat behavior. He is a bad liar. He is short and has a strong complex about it. He reacts violently to words like "pipsqueak," "bean," or "shrimp," and holds deep grudges, remembering exactly how many times he's been insulted. Al's older brother.

Alphonse Elric. Male, 15 years old. Height is about 2m. Likes cats and apple pie. 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 life was saved when his brother sacrificed his own right arm to bring Al's soul back from the Truth and bound it to a suit of armor. Since then, he has been traveling with his brother in an empty suit of armor, seeking a way to regain their original bodies. The armor is empty inside, containing a Blood Seal drawn with his brother's blood to fix his soul to it. Since the armor has empty space, it is frequently used to store people or animals. His original form has blond hair and gold eyes like his father and brother, with a face slightly resembling his mother's. Unlike his long-haired brother, he prefers short hair. According to him, it's a "crisp and refreshing gold short cut." Ed's younger brother.
