Bio: "When a wave of crimes began to plague the New York World's Fair of 1939, it seemed the event might well collapse. But then a mysterious caped figure appeared to serve as its special protector. This dark avenger was known as Gravestone [or Fantom, to some]. Very little is known about Gravestone, other than the fact that he appears to he hundreds -- possibly thousands -- of years old. He comes and goes at will, favoring the cloaking shelter of night and shadows. Gravestone is a true mystery man in every sense of the term. There are rumors that men who have tried to uncover his secrets have disappeared, never to be seen again. It is rumored that he may actually be from another dimension or world other than our own. Of the two, this rumor has garnered the most support for truth." - Protectors Handbook
Notes: Gravestone is the name Malibu Comics gave to their version of the Golden Age Centaur character, the Fantom of the Fair.
