The daughter of Princess Power is airhead Dumb Bunny. The son of Mr. Might and the Mermaid is the clumsy Awkwardman. Captain Swift's son the Blimp can fly, but only at incredibly slow speed. Rounding out the group is the Bowman's son White Feather who is a coward. The new team takes the name the Inferior Five. They soon encounter a robot created by Dr. Gregory Gruesome, designed to steal a ruby for a death-ray. By accident, the team succeeds in beating the robot. Gruesome doesn't give up, attacking the five with his crime car. While they do battle, Gruesome's assistant Hermes steals the ruby. Gruesome escapes from the heroes and is able to complete his death-ray. When the Inferior Five regroups and locates the scientist, he uses the death-ray against them.
