Empty Williams was a criminal gang leader in Dick Tracy's city. He specialized in robbery and hi-jacking. A portion of the back of Empty's head had been surgically removed. He had heavy eyelids, prominent lips, and wore his short brown hair slicked back. He smoked cigarettes, typically wore a wide red necktie with a picture of a curvaceous woman in a bathing suit on it, and carried a thin metal strap that he would use to slap his subordinates' faces if they were disrespectful. Williams had a habit of using the phrase "As a matter a' fact...".
