Well since some ###### Canoe took Wolverine already I'll have to take one of my all time favs.
Silversurfer
Why?
"
The Surfer is the fringe character that seperates humanity from the omnipotence of Galactus or Eternity, making himtops on our list. His power cosmic is so powerful that it's not a matter of what the Surfer can do, it's what he can't. Matter-manipulation, the power reserves of stars, traveling at lightspeed ... he may even be able to create life. He's truely in a power class of his own."
