Astro Boy was heading to Mr. Uhara's factory for another impossible challenge- his evil twin had studied the "Master" technology freely while he was impersonating Astro Boy. Astro Boy was now trying to figure how to stop that robot army before they left the factory. Only one conclusion- he would have to defeat his evil twin and take his place as the army's leader. If he could win he would control them and lead them to where they could harm no one- humans or robots.
Landing at the factory's gates Astro Boy could sense the danger awaiting him- then he heard his evil's twin voice- "I accept your challenge"!
