The Boonboomgers' run in the Big Bang Grand Prix is violently interrupted when the universe's top-ranked monster, Universe No. 1, appears and triggers a catastrophic universe fusion, causing parallel worlds to merge into one chaotic continuum. While Taiya Hando/Bun Red is suddenly transported to Planet Shaft, he's attacked by the Bitter Demon Beast Galaxy Circuit Guruma until Hoeru Tono/Gozyu Wolf arrives to back him up. Meanwhile on Earth, the remaining Gozyugers battle Universe No. 1. Bun Blue, Bun Pink, and Bun Black return to help, but the monster overwhelms them and defeats the combined teams. Hoeru then reappears in a dramatic new evolution: Saint Gozyu Wolf, declaring his vow to "stop the battle." With a slash that cuts through space itself, he sends all eight heroes hurtling into another dimension, setting the stage for the film's multiversal conflict.
