Adon

Adon was a student of Sagat. He was seen as a lesser version of Sagat. To prove, that he is more than that he enters the World Warriors tournament hosted by his teacher. He looses to man named Ryu, who defeated Adon with one move. Eventually Ryu won the tournament by defeating Sagat.

Sagat's defeat left Adon angered with his master. He felt that Sagat didn't deserve the title of King Of Muay Tai. He challenged Sagat for the title and eventually won. But after the match Sagat filled with anger beat Adon so badly he was hospitalized for several months. After Adon has healed he decided to search for the man, who perfected the technique, which allowed Ryu to win in the first World Warriors tournament.

Along the way he met Ken Masters. Adon found out, that Ken fights with the same fighting style as the man he's searching for. Adon decides to fight Ken to find out the moves, so that he can recognize the man, when he finds him.

Adon eventually met with Shadaloo. Bison offered Adon to join his organization, but Adon refused. Bison decided to show Adon, that his Psycho Drive power is much more powerful, that the technique Adon's searching for. They fight and eventually Bison gets the upper hand. When Bison wanted to kill Adon, Akuma appeared and temporarily killed Bison and disappeared. Adon recognized Akuma as the man, who he was searching for.

It is unknown if Adon found Akuma.

Later, while fighting in the ring, Adon saw Sagat watching his fight. He mocked Sagat and challenged him to a fight. Sagat won with only one move.

Filled with new anger against Sagat, Adon decides to enter the S.I.N. tournament to defeat Sagat permanently.
