Having killed Enter and intending to do the same with the Go-Busters, Escape battles the Go-Buster Megazords in the enhanced Megazord Zeta as Messiah's conscious surfaces and defeats Go-Buster Ace. After others save a gravely injured Hiromu, leaving despite he intent to continue, Megazord Zeta proceeds to summon ten Megazord models. As the others are better informed over the three waves of Megazords and as Go-Buster Ace is being repaired, a wounded Hiromu attempts to fight his way out of the infirmary before Nick snaps him out of it while telling him that he understands but he must also live. Once repairs are done, the Go-Busters head out to face the first wave of Vaglass Megazord with Nick piloting Go-Buster Ace to give Hiromu time to heal. After the first batch, two Alphas and two Betas, are destroyed as Megazord Zeta joins the fray as Gamma and Delta types arrive. Learning the Zeta-Type is attempting to assimilate the summoned Valgass Megazords, Go-Buster Oh and Buster Hercules destroy the second wave before the final wave, composing of each Megazord of the four main archetype, arrives. Even with the FS-O0 providing aid, Megazord Zeta absorbs the remaining Alpha, Beta, and Gamma types to evolve into the titanic Messiah Reboot. Reabsorbing Escape's data as he has no more need for her, Messiah Reboot overpowers the Go-Buster Megazords and attempt to assimilate the GT-02 and the RH-03 until Red Buster arrives in Tategami Lioh to turn the tides. Even after forming Go-Buster King, with Nick joining Red Buster in the cockpit, the Go-Busters still find themselves at a disadvantage. However, Go-Buster King separates with Go-Buster Lioh impaling Messiah Reboot with the Go-Busters' antivirus which surges through the wound as Messiah is utterly destroyed with the three Go-Busters emerging from the raging inferno. The Go-Busters then celebrate Christmas at Daian orphanage, with Rika arriving and Ryuji learning the teacher was once a resident of the orphanage, Hiromu states that they have reason to fight and live for a better tomorrow. However, elsewhere, Enter manifests and wishes the Go-Busters a Merry Christmas while he is now closer to his evolution into a new Messiah.
