Silver Surfer

Norrin Radd, a young astronomer of the planet Zenn-La, made a bargain with the cosmic entity Galactus, pledging in order to save his homeworld from destruction. Imbued in return with a portion of Galactus Powers, a new version of his original appearance, and a surfboard-like craft on which he would travel at speeds beyond that of light. Now, the Silver Surfer, he roams the cosmos searching for new planets for Galactus to consume. When his travels took him to Earth, the Surfer came meets the Fantastic Four, who help him to rediscover his nobility of spirit. Betraying Galactus, the Surfer saved Earth but was punished in return by being exiled there.
The Silver Surfer debuted as an unplanned addition to the superhero-team comic Fantastic Four #48 (March 1966). Kirby explained that the storys agreed-upon antagonist, a god-like cosmic predator of planets named Galactus should have some sort of herald, and that he created the surfboard "because Im tired of drawing spaceships!" Taken by the noble features of the new character, who turned on his master to help defend Earth, Lee overcame his initial skepticism and began adding characterization. The Silver Surfer soon became a key part of the unfolding story.
