The Hourman [Rex Tyler]; Dr. Orr; Dr. Iker (villain); Normo (villain)
The Man of the Hour faces a crazed genius, who has invented an ultra-sensory ray to create midget beings of a special composition in the 5th Dimension (having a cloud-like spidery texture), that he uses to rob. Hourman discovers they can only be seen by the use of infra-red glasses.
Letterer credit added by Craig Delich.
Dr. Iker is referred to by the beings as "The Swami," and Iker once calls these creatures "Fretties."
