The conflict between the worlds of Venus, Mars and the earth, some ten strains of mutants with various mental aptitudes as well as physical powers, and lots of gimmicks and gadgets amplify the feats of Raven (a superb telepath), representative of the World Council. His odyssey of danger, in which he attempts to keep the peace and crush subversive characters in each world, also marks the progress of homo sapiens to homo superior... A rather strenuous leap into the sweet by and by.
