The Silver Surfer (Norrin Radd) is a fictional character, a Marvel Comics superhero created by Jack Kirby. The character first appears in the comic book Fantastic Four #48 (March 1966), the first of a three-issue arc fans and historians call "The Galactus Trilogy".

Originally a young astronomer of the planet Zenn-La, In order to save his home-world from destruction by a fearsome cosmic entity known as Galactus, Norrin Radd made a bargain with the being, pledging himself to serve as his herald. Imbued in return with a tiny portion of Galactus' Power Cosmic, Radd acquired great powers and a silvery appearance. Galactus also created for Radd a surfboard-like craft — modeled after a childhood fantasy of his — on which he would travel at speeds beyond that of light. Known from then on as the Silver Surfer, Radd began to roam the cosmos searching for new planets for Galactus to consume. When his travels finally took him to Earth, the Surfer came face-to-face with the Fantastic Four, a team of powerful superheroes that helped him to rediscover his nobility of spirit. Betraying Galactus, the Surfer saved Earth but was punished in return with everlasting exile there.

The Silver Surfer was born Norrin Radd on the idyllic planet Zenn-La. His father is Jartan Radd, his mother Elmar Radd, and his half-brother Fennan Radd. All four are part of an ancient and significantly advanced civilization that has lost the will to strive or explore, leaving Norrin Radd restless and yearning for something more than the idle pleasure pursued by his fellows. Faced suddenly with the total destruction of his world by planet-consuming Galactus, Radd strikes a deal with the omnipotent space-god. In return for the safety of Zenn-La and his lover, Shalla-Bal, Radd pledges himself to serve as Galactus' herald and to seek out other planets for the world devourer to feed on. In striking this bargain, Radd also satisfies his long-held desire to adventure beyond the limiting world of his home. Accepting the young mortal's sacrifice, Galactus imbues him with a portion of the Power Cosmic, transforming him into the Silver Surfer. Radd proceeds to serve Galactus for an unspecified amount of time, unable to return to Zenn-La and Shalla-Bal. During this time, the Surfer tries to seek out uninhabited planets for the world-eater's attention, but as they became harder to find, Galactus tampers with the Surfer's conscience and removes this self-imposed restraint. Eventually, the Surfer arrives on Earth and, after deciding that the planet is ripe for Galactus's nourishment, summons his master.
