CMJ Loses His Courage
CMJ's secret identity was not all that secret as Professor Ega is able to discover it by careful study. Professor Ega's Zeta ray devise is used to transfer courage from one individual to another. The Zeta beam of the Adam Strange series (first shown almost ten years later in Showcase #17, Nov-Dec. 1958) transfers people from one planet to another. CMJ is, maybe, physically invulnerable but his soul can be tampered with. Bill Ward (GCD) did the art on this tale.
