The Autobots engage Galvatron to retrieve the Omega Lock and Planet Keys, but he uses the Keys to empower his troops. Planetary leaders confront Galvatron, who reveals his plan to destroy the universe via a black hole. United by outrage at his disregard for comrades, the five leaders defeat him using their Cyber Keys. Galvatron throws the artifacts into the black hole to cause an implosion. Optimus Prime retrieves the Omega Lock, guided by Coby, and hears Vector Prime’s voice. The items awaken Primus, who uses the Ark’s cannon to destroy the black hole. Primus transforms back into a restored Cybertron with cities and vegetation. Galvatron’s minions abandon him, and the children on Earth reunite with their families.
