Nuakan is a tall and strong man, and despite his bulk, he has great stamina and is able to move at high speed. His special move is an invincible knee kick named Hanuman Kick (ハヌマンキック?).
Nuakan was born in a poor village, but following a harsh training led him to become a legend known as the Emperor of Muay Thai. He often confronts other warriors, taking them down. One day, a young Sagat challenged him in the Khmer Ruins and managed to win, gaining his title of the Emperor of Muay Thai.
