UFO Senshi Dai Apolon

A 16-year-old boy named Takeshi starts an American football team at BlueSky orphanage. His routine is interrupted when a light appears in the sky. He learns he is the son of the king of Apolon, taken to Earth by Rabi, a retainer, to escape General Dazaan. Takeshi possesses energy abilities that allow him to control UFO saucers beneath the ocean, which transform into robots synchronized with his movements.
