Gyōten'ō of the Supernova is a grasshopper-themed alien and is one of the last remaining members of Warstar after Mons Drake's destruction and claims himself as the most powerful commander and member of Warstar (Which turns out to be true).
He is voiced by Hidekatsu Shibata who previously voiced The Omnipotent God, Daimaou, CC Patchoone, Captain Zahab, the lower mouth of Rasetsu, Trinoid 21: Reindeiasanta and Maku.
History
Gyoten'o attacks The landick Siblings. The Goseigers transform, but are powerless against Gyōten'ō as Deinbaruto thrws the stone from Rasil and unseals the Horn of Ragnarok (ラグナロクの角笛 Ragunaroku no Tsunobue) from the two stones before the Warstar aliens take their leave.
Later, Gyōten'ō & Deinbaruto are greeted by Buredoran who assumes his Warstar guise and offers his services before Gyōten'ō gives Deinbaruto the Horn to begin the end of the world. Assuring Rasil that he and the other Gosei Angels will stop it, Alata is joined his allies before they all ambushed by revived phantoms of Warstar aliens who subject them through a series of illusions before Gosei knight arrives and defeats the phantoms.
The Gosei Angels arrive to where Gyōten'ō & Deinbaruto are, transforming into their Goseiger forms to fight them and Buredoran after Gyōten'ō swallows the Horn of Ragnarok. Fighting in both his Warstar and Yummajuu guises, Buredoran uses his Bibi bugs to enlarge Gyōten'ō after Deinbaruto is destroyed. But with the Dragon header damaged during the fight, Gosei Red is unable to form Gosei great. However, Rasil's praying gives the Goseigers the Gosei Wonder Card. Summoning Gosei Wonder, they form Wonder Gosei Great to fight Gyōten'ō. With Rasil backing them up, the Goseigers manage to kill Gyoten'o and the Horn of Ragnarok with Wonder Strike.
