Sean Matsuda is a character in the Street Fighter series. He first appeared in Street Fighter III and is voiced by Isshin Chiba in New Generation and Street Fighter III: 2nd Impact and by Mitsuo Iwata in Street Fighter III: 3rd Strike. Sean Matsuda was born in Brazil, though his paternal grandfather was Japanese. A keen basketball player, his main pastime is martial arts. Sean saw veteran World Warrior Ken Masters in action at the U.S. Martial Arts Tournament and swore to become his pupil.
Sean is often referred to as the "Dan Hibiki" of Street Fighter III Third strike. However, Sean was top tier in Second impact, so this comparison is questionable, as Dan is an intentionally ineffective joke character, whereas Sean is considered a difficult to use, but still an effective character. Sean was intended to be the only fighter who used Ryu and Ken's fighting style in the game until Capcom decided that Ryu and Ken were too popular to exclude.
