A rising young author during the Golden Age of Heroes, John Law threw himself into his research for his next book a history of 'mystery men' titled Altered Egos by becoming a 'mystery man' himself. Arming himself with a 'web gun' and a costume with adhesive surfaces on the boots that enabled him to climb walls, Law became the Tarantula. He was a frequent ally of the JSA and a member of the All Stars.

Recently John learned his whole life was a lie, that he was in fact a clone of the original John Law being trained on an alien world to be sent to earth and replace the original heroes. He, along with other All Star and JSA clones were rescued by the real JSA and have begun to assimilate into 21st century culture.
