The Kikaika (literally mechanization) Empire invades our solar system, and in a matter of moments they take over and convert Neptune, Uranus, Saturn, Jupiter, and Mars, and set their sights on Earth. However, one thing stands in their way. Earth's ancient protector and warrior of light, Eldran. To fight this menace, he gifts a 6th-grade class with 3 huge robotic dinosaurs, with the power to merge and form the giant robot Go-Saurer, which they then can pilot and use to stop the Kikaika Empire's advances.
