Musical ThemeA remix of "King of the Galaxy! GingaiOh!" (銀河の王者 ギンガイオー Ginga no Ohja! GingaiOh!), arranged by Nobuo Uematsu, is played during the giant battle with Gravity Beetle. The original version from Gingaman plays when GingaiOh is summoned into battle.
By utilizing the power of the Galactic Lights, GingaiOh equips the SuperShine Armor and becomes Chosoukou GingaiOh. GingaiOh can also wield Thor's hammer in its left hand to unleash greatly enhanced versions of Thor's moves, such as "Mighty Ginga Spark".
