Dai Shi is the main antagonist of Jungle Fury. He is an ancient and evil eight-headed Chinese dragon that wants to destroy humans and rule the planet with an army of beasts. For most of the series, he uses the body of Jarrod as a vessel for his spirit.
Dai Shi is an embodiment of pure evil. He is extremely evil, cold, manipulative and completely ruthless. When he was first released from the chest that sealed him, he was forced to use the human Jarrod as a vessel. Despite this, Dai Shi had told Jarrod that he would destroy him and all humans once he recovered his true body.
Due to his powerful will, Dai Shi managed to fully control Jarrod's body. However, it was later shown that Jarrod's human nature was beginning to influence Dai Shi, as seen when Dai Shi had shown compassion for Camille and had exiled Whiger for his failure to destroy the Jungle Fury Red Ranger. With the help of the Phantom Beast Generals, Dai Shi was able to purge of all Jarrod's good deeds, making him the Phantom Beast King.
