Negadon: The Monster from Mars

It is the 100th year of Showa (2025, to be exact). Earth sends an expedition to Mars in the spaceship "Izanami". A huge rock formation is discovered beneath the surface, and is transported back to our planet. On the way back, the rock's temperature soars, causing the ship to explode and crash back to earth, leaving a large crater. The seemingly-harmless rock grows into a colossal floating saucerlike crustacean life-form called "Negadon," which proceeds to attack Tokyo. Missiles, tanks, and aircraft all attack but fail to destroy Negadon, whose thick body armour protects it from conventional weaponry. At the same time, Ryûichi Narasaki, a downcast robotics constructor, is still devastated by the incident that cost him his left eye and the life of his only child, a young daughter. The incident was caused by the malfunctioning of his masterpiece, the giant super-robot MI-6 2 "Miroku." Because of the ominous threat of Negadon, Narasaki faces the painful choice of reactivating (and piloting) the Miroku to battle the space monster and protect our world.
