After Mr. X suffered two defeats, he founded a research company, RoboCy Corporation, to cover his illegal activities. Dr. Zan, the world's top robotics expert, was recruited to create an army of humanoid robots capable of replacing important city officials. By making the switch, Mr. X planned to control the city by remote control. His criminal organization, the Syndicate, had placed bombs containing the radioactive element “rakushin” in various places in the city in advance to distract the police while the switch was being made.
Dr. Zan (also the discoverer of the rakushin element) reveals the true purpose of the research and betrays the Syndicate in an attempt to stop the action. He contacts Blaze Fielding and tells her all of the Syndicate's schemes. Blaze immediately gets in touch with his old friends, Axel Stone and Adam Hunter, and suggests that they band together to end the Syndicate's existence once and for all. Axel immediately accepts the offer, but Adam is unable to do so (due to his service on the police force) and sends his brother, Eddie “Skate” Hunter, in his place.
