The Zodiac Master works as a fortuneteller in a "mystic parlor" in Gotham City, complete with a Taurus the bull and a Leo the lion doorway whose jaws lock shut behind him when he needs to beat a hasty retreat. Employed by gangs to see how their crimes will fare in conjunction with the stars, for a 25 percent of the take, the villain plots a grand scheme of his own. However, the Batman arrests him in the act at the Gotham Museum.
