Master Key
This volume collects five Golden Age comic stories about Ray Cardell, an amateur astronomer transformed by a mysterious ray from outer space. As Master Key, he uses heat vision, X-ray vision, metal-melting eye beams, and mind control while fighting crime. The book also includes an expansion for the OGL d20 Modern superpowers system, with rules for vision-based abilities and a character-generation adjustment for creating more superheroic characters.
