The finale introduces the Prison Planet, a teleport world used as a penal colony. Graveheart and Cryos are captured by a faction of convicts led by Jewelia, a devious woman who takes a liking to Graveheart. Femur and Jade are taken by a second faction commanded by Sternum, Femur's nobler brother, from whom Femur stole the throne of Planet Bone. Convinced that their friends have been slain by the other faction, the two pairs join the fight on the side of their respective faction until the truth is revealed. Meanwhile, Lord Mantel takes control of the Alliance by force, convinced that his forces are superior to the Beast. His arrogance nearly dooms the Alliance and costs Mantel his life when Blokk invades Rock and kills him in single combat. As the Beast Planet is about to consume Planet Rock, the Prison Planet teleports into its path. Graveheart and his group use Sternum's Telepod to travel to Rock. Sternum then teleports the Prison Planet out of the system, taking the Beast Planet with it. A final battle between Graveheart and Blokk results in Blokk's demise, Jade's rise to ruler of Planet Rock, and the Alliance's new era of peace. However, the story ends with a scene in a distant part of the galaxy, moments before the destruction of Planet Reptizar at the hands of the Beast Planet.
