[Hulk] What happens if Bruce Banner or Hulk gets decapitated ?
gpt
Maybe at some point it would've fazed him, but not anymore. 

Currently, Hulk is completely immortal, so even if you decapitate him, at best case (for you) he would resurrect next nightfall very miffed. At worst - he would just reattach the head like it's nothing.
