Riza Hawkeye

Lieutenant Riza Hawkeye (リザ・ホークアイ, Riza Hōkuai) is an officer in the Amestrian State Military as well as the personal adjutant and bodyguard of Colonel Roy Mustang. A sharpshooter and weapons specialist, Lt. Hawkeye is an invaluable asset to the Colonel both in office and on the battlefield and serves as his closest and most supportive subordinate.
Riza Hawkeye is Mustang's most trusted subordinate. She carries out many of the tasks he is too lazy to do, acts as his personal assistant, and protects him from danger. She also doubles as his voice of reason, keeping cool in heated situations and scolding him when he allows his emotions to get in the way. Riza specializes in firearms, particularly sniper rifles, and can hit nearly any target with lethal accuracy to the point where she even poses as a dangerous threat to the Homunculi. She's considered one of the top sharpshooters in the Amestrian Army. Her sharpshooting skills garnered her some amount of reputation during the Ishval Civil War and earned her the nickname "The Hawk's Eye".
