When terrorist groups, evil criminals and aliens become too strong even for Earth's over-stretched armed forces, the virtually-indestructible robot, Gigantor, is built to combat them.
Dr. Buzz Bugaboo is kidnapped by Brany Mantis and forced to turn over his formula for making huge insects. The big bugs are then unleashed on the city, in number too gigantic for even Gigantor to stop.
