A massive black hole is on the verge of consuming the entire universe, including the Transformers' home world of Cybertron. As Galaxy Convoy and his team seek a way to stop it, the Transformers flee their collapsing planet and infiltrate Earth, operating as "robots in disguise." Galaxy Convoy meets Vector Prime, who reveals the existence of the "Planet Force"—an ancient artifact capable of restoring entire planets, believed lost thousands of years ago alongside Cybertronian explorers who failed to construct a space bridge to the edge of the universe.
Thus, Galaxy Convoy and the Cybertron warriors he commands set out on a grand journey across the cosmos to locate the Planet Force and awaken the ancient warrior Primus, hoping to save the universe.
However, Master Megatron and his followers scheme to seize this power for themselves, aiming to dominate the entire universe. They relentlessly stand in the way of Galaxy Convoy and his allies. Will Galaxy Convoy and his friends succeed in obtaining the Planet Force safely?
