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.
Ryu is a silent, meek, humble, submissive, self-deprecating, and respectful individual; which is often juxtaposed against the light-hearted, fiery persona of his childhood friend, Ken. He wanders the world with the desire for complete mastery of his martial art, and takes both his travels and training seriously. For Ryu, the training and the mastery that comes from the fight are all that he requires for satisfaction, declining the more material trappings of his various accomplishments as a warrior, simply moving on to his next challenge once he is victorious without delay, unless he is offered food or if he wants to converse with his friendly rivals.
While Ryu is the more serious and stoic of the two, Ken is the complete opposite - flamboyant, unorthodox and unpredictable. He is an alpha male with a giant ego and constantly reminds his opponents about his greatness. While he can be brash, egotistical, and arrogant at times, his heart is pure. He is generally kind, friendly, a good person, and very easygoing which led him into starting a family of his own. He never backs down from a fight no matter how difficult it looks.
