Johnny Sokko and His Flying Robot: 26 - The Last Of Emperor Guillotine

Johnny is shot by a very careless assassin and Emperor Guillotine pulls out all the stops, throwing his three remaining monsters at Giant Robo, causing it to be drained of energy. Guillotine then grows to gigantic size and declares himself the ruler of Earth. Giant Robo cannot defeat him, because Guillotine is made of atomic energy and traditional attacks would blow up Earth. Will Giant Robo make the ultimate sacrifice to save the planet and Johnny?
