Ryu is considered to be the "main character" of the Street Fighter series. Appearing in all Street Fighter games, Ryu's moveset is designed to be simple and beginner friendly, with a projectile and an anti-air move. Over the years, due to his simple play style, he has received many clones, including Ken and Akuma. Orphaned at a young age, Ryu was raised and trained by master Gouken. Gouken would later take on a second pupil, Ken Masters. Ryu and Ken became best friends and rivals as they trained together and eventually left Gouken's dojo. After leaving, Ryu entered the first World Warrior tournament, hosted by Sagat, the self-proclaimed King of Muay Thai. Ryu advanced through the tournament, and eventually came face to face with Sagat himself. The older Sagat nearly bested Ryu, but was defeated when Ryu was overcome with the desire to win, and thus opened himself to the Satsui no Hadou (the Surge of Murderous Intent). This gave Ryu a second wind, and he took Sagat out with a powered up Shoryuken, which would leave a large scar across Sagat's chest. .
