Major Armstrong is known as the Strong Arm Alchemist (using alchemy by sending energy through rock). Looking at his background, it's no wonder he is dedicated to the military. The house of Armstrong, for 180 years, has always played a key role in their country's government and financial circles. Generation after generation, have supported the country as Generals, which makes up their prestigious house. Armstrong's father was a General himself, and the Major hopes to follow in his footsteps.

Major Armstrong is a large man who never misses a chance to rip off his shirt and expose his muscular physical appearance hoping to intimidate those who oppose him. However, through all that muscle, he is really a kind and gentle man.

The Major's family consists of his petite and beautiful sister, Katherine and his parents.
