Martin Graves is a technologist who appears as a guest speaker on Vice City Public Radio show Pressing Issues in Grand Theft Auto: Vice City Stories. He appears to dislike psychiatrists, with Maurice Chavez predicting he will be a future serial killer. He also owns a robot, which he had built. He also dislikes Forbes Waverly III (a fellow panelist), science (for teaching human superiority), religion (stating that technology is his religion), life (which he describes as pointless and random), the British (who are obsolete) and the metric system. He is voiced by David Deblinger.
