Mirrorman is the titular hero of the 1971 series, Mirrorman.
The Earth is once again in peril as a race known only as The Invaders from the Planet X, plots to conquer our planet. The aliens soon discover the existence of Kyotaro and made plans to capture the young man. They targeted the young man because he was the half-human son of the original Mirrorman. By now Kyotaro was a young man and photographer with no interest in fighting despite the SGM captain's request. Said captain, Dr. Mitarai, was a friend of his father and Kyotaro's mother Yuko was his assistant. The young man had difficulty accepting his destiny, refusing to believe he was only half human but he soon realized that he is the only one who could save the Earth from the Invaders, when they tried to assassinate him. In the industrial district Kyotaro had his first battle as Mirrorman and fought a giant monster and an invader ship with the help of SGM.
