M. S. is an unseen character in the video game No More Heroes. Through notes he leaves in Extreme Murder Battle Stages visited by Travis Touchdown, M. S. indicates that he and Touchdown previously studied wrestling in the Canadian city of Calgary, Alberta. Fan speculation has considered the identity of M. S., judging from his initials, could possibly be the killer7 character MASK de Smith, a luchador never seen unmasked on-screen. The identity of M. S. is never explored in the game or its sequel, however.
