The first of many Terro-beasts in the Garoga Empire, Red Spark is a behemoth born from the combined strength of two silver and one gold Garoga. Smashing buildings and unleashing its chest cannon upon the city's refinery area, Hikaru found himself completely powerless against the towering crimson beast. Wasting little time he yelled out the words “Zone Double Fight!” and let the world have their first glimpse at the giant humanoid savior, Zone Fighter! Attacking with a flurry of punches and kicks, the warrior gained early ground in the immeasurable battle. Regardless, Red Spark would not be defeated so easily and turned its chest cannon upon the hero. Adding the cannon with the molten and singeing sparks from its hands, the leviathan pushed back against the silver warrior. However, in the end it would prove to be insufficient and Red Spark was transformed into a flaming carcass, thanks in part to Zone Fighter's missile bracelets.
