Colonel Roy Mustang is known as the Flame Alchemist. His gloves are made of a special material, called ignition cloth, which allows him to create a spark by snapping his fingers. He then uses alchemy to change the oxygen density in the air with the help of transmutation circles on his gloves, causing a controlled explosion. He is Edward's direct superior officer in the military, but has his own goals and intentions in mind. His main goal is to become the Führer, the leader of the military.
