Kong is Kim the invincible's son. He has purple skin with black ink markings and blue eyes. He fights using chains.

Kong was born in Chor Gom prison to his father and an unnamed hippo guard. Kong believed his father to be a good guy and was confused as to why he is imprison, even though the others tell him he tried to murder the dragon warrior (which he dismisses as a misunderstanding). Kong enjoyed the company of his friends and helps them escape the prison. He gets a job at Mr. Ping's noodle shop as an assistant cook due to his love of cooking and is later accepted as a member of the Dragon Knights after saving his boss's life.

Kong considers himself a gentlemen, and lives to uphold his father's mission to destroy the most powerful fighters in China. However, he believes that his father was a defender of China and only beat bad people. He is single-minded in his approach, letting nothing delay him for long in his pursuit of his foes. His passion is food and wrestling. However, not many wish to eat or fight with him due to his quick temper. Curiously, Kong possesses some level of courtesy as opposed to being a mere thug, evidenced by his good nature and polite mannerisms around older masters.

Kong and his father were close and both often looked to each other for support.

Kong is good friends with Emerald whom he deems as the most dazzling creature he had ever seen.
