Taiyo Sentai Sun Vulcan (太陽戦隊サンバルカン Taiyō Sentai San Barukan, translated into English as Solar Squadron Sun Vulcan) is Toei's fifth entry to its Super Sentai series. It was originally broadcast from February 7, 1981-January 30, 1982 and is the only sentai to serve as a direct sequel to the one prior, Denshi Sentai Denziman. It was Toei’s last series with a Marvel copyright, but again with no Marvel involvement in the production. The theme was air, land, and sea.
