The episode opens with Lord Mantle's funeral. As Graveheart speaks and the Alliance watches, Blokk kills three Rock soldiers. Tekla, Pyrus and Zera confront Jade to demand why she would betray them, and Graveheart reveals that it was to convince Mantle to lend them the Battle Moons for the fight with Remora. Graveheart then asks Jade to be the next ruler of Rock. Blokk enters the World Engine and kills all the Rock soldiers except the captain. He steers the planet towards the closest star. He then contacts the Alliance and demands that Graveheart face him. Voxx repairs the world engine allowing Jade to steer the planet away as Graveheart finishes Blokk off by plunging the Forcefield Generator inside him. In the aftermath, Jade makes Graveheart an official Rock citizen, and the series ends with the Beast Planet devouring another planet, the subtitle below echoing the first episode: "Planet Reptizar: On Doomsday".
