Brigadier General Maes Hughes

Maes Hughes (マース・ヒューズ, Māsu Hyūzu) is an Amestrian State Military officer stationed in the Investigations Office in Central City and Colonel Roy Mustang's best friend, as well as the closest supporter of Mustang's secret bid for the position of Führer. A devoted family man and exemplary soldier, Hughes is generally well-liked by the other characters and his murder serves as the major starting point for the greater part of the story.
Family
Gracia - His beloved wife, they always seem to have a good relationship, shown by the fact that she is hardly annoyed with his tendancies. He is shown to be, though to a much reduced extent than with his daughter, a bit obsessed with his wife. His love for her is shown when Envy takes her form right before he kills him, Maes hesitates to attack despite knowing that his opponent is a shape-shifter.
Elicia - He loves his daughter to an almost obsessed level, often showing off pictures of her to everyone he meets. He usually is berated for talking about her so often, to the point that Roy asked Maes if it was possible to send fire through a phone line as an annoyed joke. After his death, she seems to have trouble accepting (or really realizing his death, considering her age) his death, showing just how close he was to his daughter.
Career
Hughes was initially assigned to the Investigations Division in Central, he is more involved with police work than he is in actual battles and alchemical assignments. He has displayed his skills with his push knives, with very precise aiming and through the use of his reflexes. After receiving his promotion to Lieutenant Colonel, Hughes is placed in charge of the Investigations Division.

Fullmetal Alchemist (manga)
In the original manga, Hughes fought in the Ishval Civil War — not as an alchemist, but as a soldier.While not an alchemist, Hughes was an expert in knife combat (specializing in knife throwing) and carried two or four small push knives in both or either of his sleeves or in the back of his belt, which he used as protection in battle..
He had known Mustang since their days at the military academy, when they had both been idealistic as to what the future would hold. Their values changed with the war and they became critical of where the future of their country was heading toward. During this time, he introduced Mustang to a nameless sniper who had been protecting their people. She turned out to be a young Riza Hawkeye, whom Mustang recalled as the daughter of his alchemy teacher.
Years later, he married Gracia (whom he had known before the war began) and supported Mustang's plan to become Führer, doing whatever he could by "working below him and help push him to the top." After the incident in the military's 5th Laboratory, Edward Elric shows Hughes some drawings of what he saw in there. Upon further research, Hughes realizes that the military is making a huge transmutation circle around the country. He is confronted by Lust, but manages to escape with only a flesh wound by throwing a knife into Lust's forehead. Hughes tries to phone Mustang with the crucial information, but is killed by Envy before he could talk to Mustang. Hughes was 29-30 years old when he died (he is the same age as Mustang).
He is promoted to Brigadier General posthumously and buried with full honours for dying in the line of duty. His death came as a shock to his friends and family, especially Sciezka and Mustang.
Fullmetal Alchemist (anime)
Hughes is initially assigned to the Investigations Division in Central, where he is more involved with police work than he is in actual battles. He has displayed his skills with his push knives, with very precise aiming and through the use of his reflexes. In this series he first met Edward Elric on the train to Central, and aided him against Bald (Hughes wasn't on the train in the original manga storyline.[2]). He was also introduced his wife to the Elrics during their stay in Central for the State Alchemy exams and the Elrics along with Nina Tucker helped deliver his child Elica. Since then he had become good friends with the Elrics, and helped them as often as he could.
After receiving his promotion to Lieutenant Colonel, Hughes is placed in charge of the Investigations Division. While investigating the 5th Laboratory incident and the mysterious deaths of the prisoners involved with its experiments, Hughes finds that there is much to suspect about the Führer's secretary, Juliet Douglas. During the course of his investigation, he is lured by Douglas to a hotel where she had told him Tim Marcoh is waiting, but on arrival Hughes is confronted by both her and Lust - another of the Homunculi. Barely surviving against the Homunculi, he is only saved by the timely intervention of Maria Ross. He flees the building with Maria Ross, in order to contact Roy Mustang from a public telephone booth. His reason behind calling Mustang directly is to give him information that the Homunculi have infiltrated the top Military ranks and that his life may be in danger. As Mustang is on a train to Central, Hughes is not able to contact him. Hughes then notices that the Maria Ross is missing a minuscule mole under her left eye, and Envy - another Homunculus - reveals himself. After slashing Envy's throat but as Hughes turns to leave Envy transforms into Hughes’s wife Gracia. Hughes hesitates, and Envy uses the opportunity to shoot him. He is posthumously promoted to Brigadier General ironically attaining a higher rank than Mustang, although the latter later does gain the same rank.
He gets a cameo in a later episode where Envy shapeshifts into him in a failed attempt to guilt trip Ed into letting him live. He is quoted as nonchalantly telling Ed to "calm down".
Fullmetal Alchemist the Movie: Conqueror of Shamballa
Just like many of the other characters, Maes Hughes and his wife Gracia also have alternate versions of themselves living in our world, with the former possessing a slightly looser set of moral standards than his Amestris counterpart. He works as a policeman in Munich, and Gracia is a flower shop owner and the landlady of the place where Edward and Alphons Heiderich were living. By the time of the movie, they are not together, but Hughes is already trying to approach her, and Ed tells him to stop stalking her and confess his feelings to her once and for all. Their relationship starts to cool when Noah starts to live with Ed, because while Gracia supports her, Hughes, a Nazi Party affiliate, tries to dissuade Ed due to Noa’s Roma origin. By the movie's last moments Hughes finally gets the courage to speak openly with Gracia and apparently, they finally come to terms and he leaves the Nazi party.
