Trivia: Taiyou Sentai Sun Vulcan

  • The Danza: All four Vulcans share their given names with the actors playing them (Ryūsuke Kawasaki, Takayuki Godai, Kin'ya Sugi and Asao Kobayashi).
  • Hey, It's That Guy!
  • The Other Darrin: Zero Four of the Zero Girls is played by Toshiko Takashima during the first four episodes and then replaced by Kyoko Hiro for the remainder of the series.
  • Real-Life Relative: Asatarō Hyō (Asao's father in Episode 38) is played by Asei Kobayashi, Asao Kobayashi's actual father.
  • Relationship Voice Actor: Takeshi Watabe and Shozo Iizuka regularly play rivals in series such as Kikaider and Kikaider 01.
  • What Could Have Been: Despite various hints of a possible crossover between the Sun Vulcan and Denziman teams (including Queen Hedrian outright mentioning Denziman in an early episode), no such thing actually happens in the series. There was even a publicity still of both teams posing in costume that was published in magazines when the series was still airing.
    • Before Haim Saban showed interest in Bioman, Stan "The Man" Lee wanted to bring Sun Vulcan over to Western audiences. See here.
