The threat of the Machine Empire Black Magma causes the Guardians of World Peace (GWP) to decide to establish the Taiyo Sentai at a summit. From the GWP's air force, navy, and rangers, Commander Arashiyama assembles three specialists to become Sun Vulcan. Harsh training begins. Learning of this, Black Magma attacks the GWP's base, but the Sun Vulcan debuts in time to save it. Hell Saturn prays to the Black Solar God and is rewarded with a revived Queen Hedrian, now a cyborg with a mechanical heart and a metallic afro. But plot after plot of Black Magma, even with Hedrian's aid, fails. Following the death of 01, Amazon Killer, a Vader, arrives from space, destroying the Sun Vulcan Base. A new Vulcan Base is built.
