FYI, the Hulk kicked Thor's Norse god @@@.
Furthermore, given sufficient anger the Hulk would kick the Metroplis out of Superman and wipe his bum with Superman's cape after stomping a super sayen sized mudhole into Goku, Fujita and Brolic.
The ONLY reason Superman won the battle between the Hulk was that it was due to fan voting.
Besides, Superman is vulnerable to kryptonie, mind control and magic. The Hulk is vulnerable to nothing, not fire, ice, space, being underwater....NOTHING.
