His early adventures are set fighting threats at the 1939 New York World's Fair. He lives in a subterranean chamber under the Fair, and he travels via secret trap doors placed around the fairgrounds. He spots criminals by using his "crimetracking televisor". During the time between the 1939 and 1940 Fair seasons, he travels in a series of stories set outside the Fair. He was often shown during these outside stories in a simple suit, with a hat brim hiding his features.
