Wu Shi are powerful warriors enslaved by Hei Long. They are infused with dark energy, thus makes them demonic. There are totally six of them: An (暗), Hui (毀), Du (毒), Wu (無), Duo (奪), and Zun (尊) - two of them being Lei Ke Si (雷克斯) and Tian Hong Guang (田弘光). Wu (無) is known for attacking his targets by turning into someone they care about. After the KO fighters defeat Hei Long, the Wu Shi were freed from his control.
