The Silver Surfer began life as Norrin Radd, a humanoid alien from the planet Zenn-La. When the world devouring supervillain Galactus threatened to destroy his planet, Radd made the agreement to become the villain’s herald, searching out other planets for him to consume. Galactus infused Radd with the Power Cosmic, which is what transformed him into the Silver Surfer.
What’s the Power Cosmic? Well, basically it’s a collection of cosmic energies that permeate throughout the universe that the Silver Surfer can control. And it lets him do just about anything. He can augment his strength to incalculable levels and make his body almost indestructible. He can navigate space and dimensional barriers. He can fly at near-limitless speeds on his cosmic surf board, entering hyperspace when he exceeds the speed of light. On occasions, he’s even proven himself capable of time travel. He doen’t require food, drink, air or sleep, and is sustained entirely by converting matter into energy. He is immune to temperature extremes and most radiation, and can survive in the vacuum of space. He can analyze and manipulate matter and energy, restructuring or animating it at will. He can heal mortal wounds, and has shown to be capable of evolving organic life on a planet wide scale. He can cast illusions, absorb and fire energy blasts, manipulate gravity, and phase through solid matter. His senses enable him to detect objects and energies light years away, and to perceive matter and energy in subatomic detail; he can even see through time, and, with concentration, achieve limited perception of past and future events in his general vicinity. To top it all off, the Silver Surfer has even demonstrated limited telepathic abilities, and has proven able to influence human emotions and sensations.
When it comes to having an over abundance of overpowered superpowers, there’s really no topping the Silver Surfer. He might have started out as a slave to Galactus, but, over time, he’s managed to evolve his cosmic abilities far beyond what was originally intended.
