John Rainbird was a Native American, working as an agent/assassin for The Shop. He was a badly scarred Vietnam veteran.
He killed Andy McGee and Joseph Wanless. After killing Andy, he tried to kill Andy's daughter Charlie McGee, but she melted the bullet and burnt him and James "Cap" Hollister to death (in the book).
