(アドン?, Thai: อาดอน) appears in the original Street Fighter as a Muay Thai warrior that the player faces before the final match against Sagat. He also appears in Alpha, Alpha 2 and Alpha 3. In the first three Alpha games, Adon is characterized as a former pupil of Sagat, seeking to surpass his disgraced master by defeating him, and in Alpha 3 he tries to track down and challenge Akuma. He briefly appears in Sagat's Street Fighter IV prologue, where he is again defeated by Sagat. Adon is a playable character in Super Street Fighter IV. Like Birdie and Eagle, Adon and Sagat share a motif: both characters' special moves are inspired by felines, the jaguar and the tiger.  Adon appears in the Street Fighter cartoon series as a non-speaking fighter in the episode "The Medium is the Message". He also makes a brief cameo in Street Fighter Alpha: The Animation as one of the fighters accompanying Ryu to save Shun from Professor Sadler. He gets into an argument with Birdie and is later shown fighting with Rolento in the base's arena.

Ryu, the current Street Fighter champion, must overcome the power of the "Dark Hadou" which consumed Akuma, the brother of his sensei, Gouken. Plus, he deals with the unexpected arrival of Shun, a young boy who proclaims to be his long-lost brother.
