Street Fighter Alpha/Ryu

For more information about Ryu, please see his Street Fighter II entry.

In the original Street Fighter, Ryu is one of the participants of the World Warrior tournament. After defeating all challengers, his skills earn him the right to fight its host, Sagat. Despite nearly losing against the "Emperor of Muay Thai," Ryu secures a difficult victory, and is crowned champion.

Later games elaborate on the final battle between Ryu and Sagat. In this version of the battle, Sagat nearly beats Ryu into unconsciousness. Ryu, however, having such a strong desire to win, allows himself to be engulfed by the Satsui no Hadou and he strikes Sagat with a nearly-fatal Metsu Shoryuken that it not only knocks Sagat unconscious but also marks his chest with a great scar. After regaining consciousness and discovering what had happened, Sagat swears vengeance on Ryu.

In the Street Fighter Alpha series, Ryu leaves Sagat behind and returns to his home only to find that Gouken, his master and adoptive father, has been murdered. Learning that Akuma had fought and killed his adopted father, Ryu began to travel the world to find this man.

He encounters and fights Akuma on a secluded island known as Gokuentou, but Akuma was only testing him. He senses that Ryu has the same powers as he does, and tells Ryu about the Satsui no Hadou - a power that consumes the practitioners of their shared fighting style, driving them to win even when it means killing the opponent. Ryu refuses to unleash this power within, and Akuma uses his fist to smash the island, leaving Ryu stranded.

Sometime after escaping the island, Ryu battles Ken and loses. Ken realizes Ryu is not himself and has been deeply troubled since his last victory over Sagat. He gives him his red hairband as a reminder to stay focused, which Ryu was sincerely grateful for. Soon thereafter, a fan of his, named Sakura, comes up and expresses her desire to train under him. Ryu replies that he himself still has much to learn, but allows Sakura to take a picture of him. She swears to make him accept her eventually.

Two years later, Ryu continues to be troubled by what Akuma had told him, compounded by his encounter with Rose, who has intricate ties to M. Bison. She tells him that he cannot defeat Bison unless he fights him at the cost of his soul. True to form, when Ryu confronts Bison, he is defeated despite putting up a valiant fight. Bison takes the semi-conscious Ryu and begins brainwashing him, using the revelation that the Satsui no Hadou - the dark power Ryu struggles to avoid using - is akin to Bison's own Psycho Power.

This scene is interrupted by the entrance of Sagat, Ken, and Sakura, each of them having followed Ryu for their own reasons. While Ken and Sakura distract Bison, Sagat challenges the brainwashed Ryu (different versions of this story coexist; in one version, Sagat is offered this battle as an enticement to stay with Shadoloo.) Sagat quickly notices the effects Bison's brainwashing have had on Ryu, and, at Sagat's urging, Ryu comes to his senses and helps Ken and Sakura force Bison to retreat.
