The Doron Empire from the Ganymede System discovered Earth as an ideal world for them to conquer.

Almost completely succumbed to the empire, Earth is at its last days, and one scientist, Dr. Shikishima, had only one hope in restoring Earth from its alien conquerors--- a massive mecha known as the Mechander Robo, specially programmed and designed to battle these invading aliens from complete takeover of Earth.
