7. Silver Surfer:
The Silver Surfer has a history of being a bad ass with Bruce. In Tales to Astonish #92-93, Silver Surfer literally smacks him with his surfboard and in another scene used the power cosmic to render him unconscious. In Incredible Hulk #250, Silver Surfer asks him to help him break through the force field that was keeping him on Earth called the Galactus. When Hulk flips out on him, the Surfer removes the gamma radiation from Hulk’s body using his power cosmic. Bruce Banner was cured for a while there.
