Synopsis

The Kikaika Empire launches an invasion of our solar system, swiftly conquering and mechanizing Neptune, Uranus, Saturn, Jupiter, and Mars before turning their attention to Earth. Standing in their path is Eldoran, Earth's ancient guardian and warrior of light. To combat this threat, Eldoran bestows upon a fifth-grade class three massive robotic dinosaurs, capable of combining into the colossal robot Gosaurer. The children then pilot this mighty machine to halt the Kikaika Empire's relentless advance.
