Guile

How Guile joined the Tourney
When Guile was a trainee in the United States Air Force, he befriended his superior officer, Charlie Nash and asked him to teach him in his unique form of fighting, which Charlie agreed to do. Guile learned the style, but his hot temper caused him to lack proficiency in the moves (shown in how Charlie can shoot Sonic Booms with one hand, while Guile needs both).
