Road of Justice (正義ノロード Seigi no Rōdo) is the fiftieth and final episode of Engine Sentai Go-Onger.
The Go-Ongers manage to enter Hellgailles Palace and battle Yogoshimacritein as he absorbs power from the Deus Haguru Magear. But once they trap him in the Bikkurium Chamber, Go-On Red uses the primary Engine-powered Kankan MantanGun to destroy the gear. But the destruction of the Deus Haguru Magear causes Hellgailles Palace to self-destruct with the three Go-Ongers running for their lives in Engine-Oh. However, Yogoshimacritein managed to reconstruct himself after Hellgailles Palace's destruction as he decides to destroy the city in retaliation. But the Go-On Wings, Go-On Black, and Go-On Green return and hold him off until the primary Go-Ongers arrive. Though the Crime Minister boasts of invincibility, the Go-Ongers refuse to give up and hit him with their Go-On Bonds Special. But when Yogoshimacritein Third Industrial Revolutionizes, the other Engines arrive as they all form Engine-Oh G12 to stop Crime Minister once and for with their G12 Final Grand Prix. With the Gaiark finally defeated and the Human World safe, the Engines must leave their partners and return to their world. After saying their goodbyes to the Engines and Bomper, the Go-Ongers see their friends off. Several months after their parting, after Gunpei scolds Hant for messing with his handcuffs, they pick up Saki from her bakery before arriving to see the Sutō siblings at their high society party, taking them to the Twin Ring Motegi where the Go-Ongers began. Renn meets them there as they all see Sōsuke before the seven reminisce of the good times they had over as Go-Ongers until they get a surprise visit by Speedor and Bomper, who reveals the missing President of the Gaiark is attacking Gunman World and they need their help in dealing with him. The Go-Ongers accept the offer without second thought and head off on another adventure.
