Originally posted by roughriderI doubt Hulk would turn into a vamp. However, if they all managed to bite Hulk at once (or in close succession), their venom could possibly be able to put him to sleep, as well as cause a tremendous amount of pain.
Hulk's not immune to getting bitten though, is he? Magic trumps science. It only takes one of them. One version of Hulk from Marvel's Ultimateverse got turned into a vampire.
