Ultraman Ace (series)

Ultraman Ace (ウルトラマンA（エース） Urutoraman Ēsu?) is the 5th show in the Ultra Series. Produced by Tsuburaya Productions, the series aired on Tokyo Broadcasting System from April 7, 1972 to March 30, 1973, with a total of 52 episodes.

Starting with this show, the Ultra Series heads in a notably different direction, slowly shifting from a sci-fi/mystery adventure to full-tilt superhero fantasy fare. Also, all previous Ultraman like Ultraman, Ultra Seven, Ultraman Jack (from The Return of Ultraman) and also with Zoffy make more frequent appearances here, whereas they only made guest appearances in the previous show The Return of Ultraman.

Plot
Yapool, an ancient interdimensional creature from ancient times with similarities to Satan and Legion, sought after the planet of Earth and tried to conquer it with a campaign that involved his experiments known as Choju. The first super weapon sent to Earth, Velokron, ravaged a city and took on TAC, a special forces unit created by the Self Defense Force to defend the Earth from kaiju. Two of Verokron's unfortunate victims were Seiji Hokuto and Yuko Minami. Before they were dead long the first five Ultra Brothers: Ultraman, Zoffy, Ultra Seven, Ultraman Jack, and Ultraman Ace, decided to revive the duo for trying to help young children get away from the Choju and to fight off Yapool's forces. Ace decided to be the one to go as he had both of them be his host. Yapool has used not only Choju, but also recruited other aliens, humans that sold their souls to him for Choju possession, and even himself to assassinate Ace and TAC only to be brought down in absolute defeat. After the destruction of one of Yapool's oldest Choju, Lunatyx, Minami revealed she was one of the last natives from the moon and gave her Ultra-Ring to Hokuto as she had to leave, but she would return every once in a long while. Ever since Hokuto has been Ace's host and their efforts were just the same. Yapool became desperate by combining the bodies of a selected few to create Jumbo King only for him to fail and have Ace fly off to his home world of the Land of Light in M78. Ever since Ace has showed up to help later Ultras in their times of need.
