Gouken (Japanese: 剛拳, Hepburn: Gōken) is a fictional character in the Street Fighter video game series. He is the martial arts master who trained Ryu and Ken, as well as the elder brother and former training partner of Akuma. Gouken is usually depicted as a bearded man who wears Mala prayer beads on his neck and a karate gi with the kanji mu (無), or "void" sewn to the back. Although Gouken has been a supporting character in the Street Fighter series since Super Street Fighter II Turbo, he did not make his first full-fledged appearance in the video game until his appearance as a hidden character in Street Fighter IV.
