Lin was a member of the Red Dragon Crime Syndicate along with his brother, Shin. He partnered with Vicious until his death on Callisto.

Recessional of the Red Dragons
Both Shin and Lin appeared before Trudy, during one chilly night at the vast frontier of Mars. They assured her they're not working for the enemy, but rather as guidance to her. Shin explained that he protected Spike during all those deadly shootouts at Tharsis while Spike was pursuing Vicious; in Shin's dying breath, his last wish was for Spike to become the new leader of the Syndicate. While Lin said that he actually protected Spike as he covered Vicious, then shot the former with a tranquilizer bullet. He never wanted to harm Spike, and much like huis brother, he wished for Vicious to fall so Spike would defend Mao Yenrai's honor. Since Trudy was determined to eliminate the crime organization for good, they wished her and the special forces luck.
