The Silver Surfer is a humanoid alien with metallic skin who can travel through space with the aid of his surfboard-like craft. Originally a young astronomer named Norrin Radd on the planet Zenn-La, he saved his homeworld from the planet devourer, Galactus, by serving as his herald. Imbued in return with some portion of Galactus' Power Cosmic, Radd acquired vast power, a new body and a surfboard-like craft on which he could travel faster than light. Now known as the Silver Surfer, Radd roamed the cosmos searching for planets for Galactus to consume.
