Lung (Dr. Sin)
An ancient Chinese Dragon unleashed by Xin Fang
Lung is a powerful and ancient Chinese Dragon who was long ago bound inside a bronze dragon statue. Xin Fang acquired the statue and managed to free Lung and either bind him to his service or make some sort of deal with him.
Lung was sent to London to work for Xin Fang. There he assumed the identity of a local chinese crime lord (Dr. Sin). He was attempting to find a jade sword that also had the power to bind various mystical beings inside of it. Gun, Dubito and Dynasty intervened and managed to imprison Lung within the sword.
