Gouken is Ryu
original master, as well as the older brother and former sparring partner
of Akuma. Gouken and
Akuma were apprentices of Goutetsu, a martial arts master
who taught the brothers an ancient assassination style. Akuma embraced
the murderous nature of this style, and eventually killed Goutetsu in combat
after mastering the forbidden technique of the Shun Goku Satsu.
Gouken refined the techniques of this murderous style and developed them
into a pure martial art, which he then taught to two pupils: Ryu and Ken. Dan
Hibiki also sought out training from Gouken, but Gouken expelled him from
the dojo once he learned that Dan's motive was revenge. Gouken is also an old friend of Retsu's.
Prior to the events of the Street Fighter Alpha series, Gouken was
challenged by Akuma to a death match and was defeated. Ken and Ryu thought their
master was dead, and Ryu began his quest to avenge his master's apparent death in Street Fighter Alpha
2. Gouken has always been a supporting character in the Street Fighter
series since SSF2 Turbo and Street Fighter Alpha, but made his
first official appearance as a playable character in Street Fighter 4.
