Space Ace (Japanese: 宇宙エース, Hepburn: Uchū Ēsu), also known as Uchuu Ace, is a Japanese science fiction manga series written and illustrated by Tatsuo Yoshida and serialized in Shueisha's Shōnen Book magazine from June 1964 to May 1966.

It was adapted into an anime television series by Tatsunoko Production[2][3] and aired on Fuji TV from May 8, 1965, to April 28, 1966.

His tool of preference is the galaxy ring, a flat white hoop he can produce from his fingers to be thrown or ride on.

Providing the show's comedy relief was crusading investigative reporter Yadokari, who usually burst on the scene riding his jet skycycle at the worst possible moment, screaming for Ace to give him interviews and so on.

One of the show's most important characters is "Ebo", Ace's imagined projection into the night sky depicted as a humanoid robot.
