In this issue, Wonderguy encounters a villain named the Shape Master. He used to be Ernie Schwump, a shiftless worker at a government research facility, until he messed with some equipment he should not have. Now he is able to change shapes at will, and he decides to use this power. It's up to Wonderguy, Claire, and Dillon to find his weakness, and put a stop to his shenanigans.
The mathematics concepts of the volume of a rectangular prism, cylinder, and sphere are presented.
