A scientist Siroco created Tondo, the Omnipotent robot, for space exploration. The planet where Tondo was created is not named, but a man whom Sirco calls 'Your Excellency' desires to use Tondo to explore possible worlds to invade and spread despotism. Tondo's first mission took an unexpected three years. He returns in bad shape, appearing damaged. Tondo shows moving pictures of the planet, displaying a desolate and unlivable planet. This dissuades the would-be invaders. Tondo's next mission is to Earth. Tondo intends on protecting the Earth by again deceiving the despotic conqueror.
