The giant Boring Banki attacks the city until the Go-ongers arrive, letting Carrigator rest due his massive recharging as the primary Go-ongers attempt to use Speedor and the others. However, the primary Go-ongers learn their Engine partners are unable to enlarge due to Bombe Banki's attack. Then, Boring Banki burrows its drill underground and enters a sleep mode. By then, the Pollution Ministers arrive to take out the Go-ongers personally with the Engines disposed of, defeating them easily with their barrier attack. Later, after an attempt of removing the rust with a miracle and Speedor not being as confident, an upset S?suke runs off to vent his rage until he receives aid from his racing coach: Tojiro Fuji. Seeing that S?suke still the same as he was, a miracle maker who acts on his own, Tojiro reminds him that even heroes need the support of others. S?suke finds Speedor, who almost got himself kill to find his human. Though S?suke apologizes for his actions, Speedor stays the true miracle was their meeting. As S?suke resumes de-rusting Speedor, Gunpei and Hant learn that Boring Banki plans to drill into a magma chamber below the city in order to destroy it in an eruption. The two transform to fight the Pollution Ministers before Go-on Blue and Go-on Yellow arrive after restoring their Engines to cover the two as they form GunBir-O to stop Boring Banki, only to overpowered by the stronger opponent due to Carrigator not being at full power. But at the last second, S?suke arrives with a fully restored Speedor. Using the Highway Buster three times, the Go-ongers take out the Pollution Ministers' barrier before forming Engine-Oh to support GunBir-O. Together, Engine-Oh and GunBir-O scrap Boring Banki with their attacks as Tojiro watches in pride of S?suke's miracle coming true.[8]
