Silver Surfer

Species: Zenn-Lavian
Enemies: Galactus, Doctor Doom, Mephisto, Annihilus
The Silver Surfer first pops up in the comics as the herald of Galactus. Given power from the “eater of worlds,” the Surfer is able to travel to any galaxy or system quickly. All the while, operating sort of as a scout to find the best planets for Galactus to consume. Originally known as Norrin Radd, the Zenn-La humanoid was a young astronomer who had a bright future ahead. Yet when Galactus showed up to consume his world, Radd said he would be a herald for him if he let his planet remain. Galactus agreed and gave Radd a portion of the power cosmic to do the job. This gave him near invulnerability.
Radd also absorbs and manipulates the universe’s ambient cosmic energy. He can also travel faster than the speed of light, which is necessary when you’re trying to feed the eater of worlds. Yet one day, Silver Surfer finds Earth and brings Galactus there. With the help of the Fantastic Four, Radd is able to reconnect with his noble self. He betrays the world eater and is then exiled to Earth. Yet the Surfer keeps most of his powers, and he eventually becomes a cosmic hero for many alien worlds. All of this
