Voltes could not volt-in. International Army helped Voltes by attacking the robot with missiles. The Boazanian launched the second robot, Gamenza, to destroy the army. Dr. Hamaguchi uncovered his secret weapon, "Ultra Falcon Beam System" canon, or known as "The Ultra Magucon". When Namazungo tried to disrupt the Volt-in sequence again, Hamaguchi fired the beam canon into Voltes formation. But after that single shot, the canon exploded.
