Bio: This unnamed hero operated from underneath the 1939 New York World's Fair in an underground lab connected to an underground river. He guarded the Fair and fought those criminals and racketeers who threatened it. He later became known as "Fantoman." He had no powers, although he was very strong and fast and was good at hypnosis. He was also very hard-boiled and quite willing to torture enemies to get what he wants. His activities quickly spread beyond the World's Fair. Little is known of him beyond this and the fact that he did not speak.
Notes: When Malibu Comics revived this character in the 1990s for their Protectors series, he was renamed Gravestone.
