Synopsis for "Destroy Doc Magnus"
Mr Conan gathers the Metal Men and reveals that not only has Doc Magnus come out of his coma but that he has had his mind altered and turned to evil. The disguised robots are to travel to the nation of Karnia, where Doc is developing a robot army for the dictator Karnak, and assassinate their creator.
Upon landing in Karnia, the Metal Men take the place of a squad of robot soldiers, then make their way to Karnak's base. They ruin the equipment that controls the war robots and accidentally cause the death of Karnak, but Magnus shoots Platinum and makes good his escape, vowing to destroy all of the Metal Men.
