Sho Hayate is played by Kazuoki Takahashi, who would go on to play Hakko Kita, the sidekick of another guy named Tsurugi.
Episode 45 has two future stars from Choushinsei Flashman: Yutaka Hirose (Ley Wanda, who would also go on to play later Super Sentai villains such as Dr. Kemp, Tranza, and Jin Matoba) as a military guard; and Yoko Nakamura (Sara/Yellow Flash) as Tsurugi's alien lady-friend Aila.
What Could Have Been: The Working Title was "Uchū Sentai (Space Squadron) Cosmoman" and the show was originally going to have a space exploration motif. While it was changed to a military motif at the end, traces of the original motif are still evident in the design of the Change Robo and the Shuttlebase, not to mention the fact that the villains are space aliens. And possibly, the choice of final title was influenced by this, as the team's symbol is a "CM" which could stand for either Cosmoman or Changeman.
