@green_skaar: it's not non sense. A hulk should not be able to beat up a watcher or a powerful herald of galactus. Some characters are made over powered for the sake of the story.
didnt hulk already do this in planet hulk? though its debatable whether or not he should. (caught surfer off guard,he wasnt fighting back etc )
Yeah Hulk fought SS in Planet Hulk, but the fight doesn't tell us a whole lot, since both were weakened and Hulk had help.
