A year after defeating Yogoshimacritein, the Go-Ongers head to the wild western realm of Gunman World to defeat Gaiark's Pollution President Batcheed in a final confrontation. However, after defeating Engine-Oh G9, Batcheed opens up a dimensional rift that sucks the Go-Ongers and Engines to other Braneworlds. Soon after, while finding themselves fighting Ugatz, the Shinkengers encounter Go-On Red as he helps take out the Ugatz on his own, much to the Shinkengers' shock.
