Atragon

The Earth shakes violently. The tremors are caused by the undersea Mu Empire, a belligerent dominion seeking to reclaim their rule above sea level. The Muans are aided and protected in their crusade by their God Manda, a gigantic sea serpent dragon. But all hopes rest on Captain Jinguji and his super submarine Atragon to stop the Muans - yet the captain has no interest in committing his submarine to battle against the Mu Empire. That is, until the Muans kidnap his daughter. Now the Atragon, equipped with a high-powered freeze ray and the capability of flight, must face the apocalyptic weapons of the Mu Empire to save humanity!
