While Ryu is the more serious and stoic of the two, Ken is the complete opposite - stylish, unorthodox and unpredictable, as well as being much more violent and aggressive than Ryu. 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.
