[1] In college studying archaeology, Dai Sawamura deciphers the symbols of the Nazca Lines in Peru.

Impressed by this feat, the Galaxy Federal Police (銀河連邦警察, Ginga Renpō Keisatsu) recruit and train him to be Earth's third Space Sheriff.

He's given the code name Shaider in memory of an ancient warrior who defeated Emperor Kubilai and brought down his Fuuma Empire 12,000 years ago.

The residents of this realm revere Kubilai as a god while carrying out his intent of conquering the universe through psychological attacks on many planets, destroying worlds like Gao, Omega, Mind, Gor, Marine, and Mount before targeting Earth to establish the second Mu Empire.

Eventually, on Kubilai's birthday, Fuuma celebrates by systematically destroying every planet while pressing hard on their goal to conquer Earth.

Placed within boiling Fushigi Seawater, the pearl enlarges into a giant egg that Kubilai hatches with his beam.

Space Sheriff Shaider (宇宙刑事シャイダー, Uchū Keiji Shaidā) takes place between episodes 19 and 20, and was released on July 14, 1984.

A video game based on the television series, The Space Sheriff Spirits, was released for the PlayStation 2 system on May 25, 2006, by Bandai Namco.
