Lin is a member of the Red Dragon Crime Syndicate, and the brother of Shin who also worked for the Red Dragon syndicate. He worked under Spike Spiegel when he was a syndicate member. While he remains loyal to those he is pledged to serve, Lin does not agree with needless violence. He was sent by the Elders to protect Vicious. When Spike encounters Vicious on Callisto Lin is the one to shoot Spike before he and Vicious can fight. The gun he used was a tranquilizer that knocked an unconscious Spike to the ground while Lin and Vicious could escape. Lin is killed during the Red Eye drug deal between Gren and Vicious by jumping into a bullet Gren aimed at Vicious. It is possible that Lin is the fallen warrior Laughing Bull was referring to at the beginning and end of Jupiter Jazz, as Spike mentions that Lin's soul is lost due to him dying to protect Vicious.
