Just as the Watcher has warned, Galactus has arrived at Zenn-La to consume its energy. Norrin Radd sacrifices himself by offering to serve as Galactus' herald, whose job it will be to scout out planets without intelligent life so that Galactus won't destroy any civilizations. On the upside, Galactus gives Norrin a portion of his powers, turning him into the Silver Surfer. On the downside, the transference of powers remove Norrin's memories and his moral convictions! With no memories, the Silver Surfer finds world after world for Galactus to devour, but the herald is troubled by the destruction. The evil Thanos uses Ego the Living Planet to invade the Surfer's mind, intent on finding the secrets of Galactus within. The resulting mental battle unleashes the Surfer's memories and he goes to confront Galactus. When Galactus decides to attack the Earth, the Surfer rebels, attacking the world-eater. Although the Surfer cannot harm Galactus, he is allowed to return to Zenn-La. When he gets there, he discovers that the planet has been moved, and he is now alone in space! The Surfer vows to find Zenn-La, and his beloved Shalla Bal.
