In the far reaches of space, a new star emerges. At that very moment, a horrible roar sweeps across the universe. This sudden roaring, like a helpless howl, breaks the peace of the universe. Antarichi, a planet of peace and perfection, is overtaken by a greedy bionic human named Alfred. Opposing the belief of his creator, Casiofia, he attempts to conquer the Universe. His first step is to destroy the city of Orion. Kanann, King of the city of Orion, is shocked by the sudden attempt of the newborn star. Finding no way to combat it, he sends out SuperSpeeder to seek help from Earth. A fierce and bloody battle begins. With the reunion of Super Speeder and Mazinger 7, along with a group of brave warriors, Alfred is finally defeated. The bionic human is exploded and the colony destroyed. City Orion is rebuilt and the Universe is back to peace, thanks to the Protectors of the Universe.
