Maes Hughes

Brigadier General Maes Hughes was an overprotective and proud father of a three-year-old (in the manga) or four-year-old (in the anime) daughter. Hughes was, upon introduction, a major, and later a lieutenant colonel, notable for being a close friend and confidant of Roy Mustang. Hughes constantly praises his daughter, and carried her picture constantly. He was also a devoted husband, friend, and officer. Protecting Edward Elric, Hughes began investigating the Philosopher's Stone. When he realized the suspicious background of the Fuhrer's secretary, actually the Homunculus Sloth, he was killed by Envy in the form of his wife.

Trivia

 * Maes was possibly more popular then Ed and Roy, seeing as many fans were saddened by his death.
 * As a running gag, Maes would always talk about his daughter (mainly to Roy and Ed, shoving a picture of her in their faces and loudly saying things like "Look at my beautiful daughter Elicia!"). Despite this, many people were very upset when he died.
 * Maes death is somewhat changed from the manga; in the anime, it was Maes who initially attacked Envy.
