The Vacuum Master
While this is an overall clever idea for a menace there are some contradictions. In Junior's first confrontation with Vacuum Master he thinks, "Hey, no voices! But naturally not! Air carries sound! There's not sound in a vacuum such as this!" On the last page CMJ tosses the big bomb into outer space and states. ""I'll shove it away from the Earth into space! Space is just a big vacuum itself, so the bomb belongs there!" There is another CMJ story where he actually talks in the vacuum of outer space. Art by Bud Thompson. The vacuum gimmick was used in a somewhat different context in an Adam Strange story "The Weapon that Swallowed Men!" (Mystery In Space #63, Nov 1960).
