When early American astronauts reported seeing "fireflies" in space, they posed a riddle that intrigued men of science for decades. In the year 2000, the intrepid Doctor Bolt - astronomer, adventurer, astronaut ~ decided to investigate on his own. Soon after entering orbit, he spotted the mysterious fireflies and attempted to capture some in a special chamber of his capsule. Suddenly, the chamber began to grow cloudy! Doctor Bolt's brain began to burn. The cosmic "fireflies" were not fireflies at all, but a horde of Mist Men hovering in space, awaiting just such an opportunity. Our atmosphere prevented them from entering directly, but when borne by a human host, they could come to Earth, invade men's minds, and so conquer the planet! Doctor Bolt returned to Earth a man possessed: soon after, important men from all walks of life found themselves possessed too and forced to perform evil acts that threatened public safety! All seemed doomed until a Mist Man attempted to seize control of Astro Boy. The Mist Man had never encountered a robot before, and so was unaware that Astro Boy’s mind was impervious to attack. Listening to the Mist Man within, Astro Boy soon learned the details of the plan for conquest. With the help of Doctor Elefun, the Institute of Science, and a specially designed vacuum cleaner, Astro Boy dispels the Mist Men and sends them back to outer space.
