Collects PLANET HULK: WORLDBREAKER #1-5. Return to Planet Hulk! A thousand years from now on Planet Sakaar, a high priestess fills a stone starship prison with small, green children - and a young woman with emerald skin searches for the legendary Green Scar to help save her brother from a group of apocalyptic cultists. But which Hulk will she find? And after all these centuries, is he truly the Sakaarson, who will save us all - or the Worldbreaker, who will destroy us? On a world broken again and again by prophecy and catastrophe, the Hulk must find the will to fight again! A shocking expansion and culmination of the mythos of Sakaar and the heart of the Hulks from original PLANET HULK scribe Greg Pak!
