The plan might have worked, had not a giant robot-lying in disassembled form-been discovered by Doctor Elefun and Astro Boy. Instructions for assembly were found upon the monster robot, instructions written in a code like none on Earth. Thanks to Astro Boy’s computer-like mind, the code was quickly deciphered. It proved to be a secret message issued to an Earthling posing as a friend of Humanity (when in reality he was an undercover agent for the invading forces!) Exposing the agent was only half the task. Astro Boy was forced to grapple with the assembled monster – a cosmic giant too formidable for even Astro Boy to tackle! In a brilliant stroke of logic, Astro Boy tricked the monster into reversing the Earth’s specific gravity – a feat that sent the giant careening back into space and kept the planet free for humanity.
