Adon was took under the wing of Sagat three years after Sagat was announced God of Muay Thai. Adon was considered a less skilled fighter than Sagat, but yet he was a more acrobatic fighter than Sagat. Adon participated in the first World Warrior Tournament to prove he was more than an underling of Muay Thai God, Sagat. The arrogant Adon did not take the tournament seriously, he faced Ryu, and was taken out with a single Shoryuken. After that battle, Ryu went on to fight Sagat, Ryu then defeated Sagat, which would lead to Adon's breakdown.
Adon did not become angered at Ryu because of his defeat, he was angered at Sagat for not being able to show that he was truly a Muay Thai god (Sagat lost to Ryu in the world tournament). Adon challenged Sagat for the title of God of Muay Thai, he was sucessful with the challenge, but the vehement Sagat inflicted alot of damages on Adon forcing him to go to the hospital to treat his injuries.
Adon's injuries eventually healed and he was restored to his normal state hoping a new fighter would captivate his attention. Then a rumor had spread of a fighter who had mastered Shoryuken (The power that lead Ryu to win the first World Warrior Tournament). Adon vowed to find this fighter and claim the power for himself.
