Fastball (whose real name is John Malone) was a former baseball player whom the Overmaster equipped with an exoskeleton, gloves and the requisite wrist bands to enable him to pitch potentially deadly explosive spheres.[1] He was drafted into the Overmaster’s first Cadre, but after their defeat at the hands of the Justice League, Fastball went underground and was largely forgotten. Another villain with a similar motif, named Overthrow, was often mistaken for Fastball. The real Fastball finally returned to a life of crime, rejoining the Cadre under the leadership of Doctor Polaris in San Francisco.
