UFO Senshi Dai Apolon

The story is about a 16-year-old boy Takeshi who recently formed an American football team at the Blue Sky orphanage. One day the game is interrupted by a light in the sky. Takeshi discovers he is the son of the king of the planet Apolon, spirited away to Earth by his father's retainer Rabi to avoid death at the hands of General Dazaan. He turns out to have special energy abilities which can control UFO saucers and the robots that form Dai Apolon from a base under the ocean floor. His friends Miki, Matsuo and Goro also become pilots. They magically change into their uniforms every time they yell U! F! O!. With the robots they attempt to save the world.
