Guile is a tough man, both physically and mentally, who takes pride in family, and is a loving husband and father to his family. A stoic man at heart, Guile's calm and emotionless exterior actually hides intense feelings, especially the fury after Charlie's death. Although loyal to the Air Force and the United States, Guile is extremely persistent. He always seeks to get the bottom of the matter, especially concerning Shadaloo, M. Bison and what happened with Charlie Nash, which has led to problems with his superiors (although they have high respect and esteem to him) and has caused pain to his family, this hurts him deeply.
