If we take Immortal Hulk as canon, then Hulk is literally unkillable in a way that only the gamma powered characters can utilize. To a point where he can survive the death of the universe (or become it).

Immortal Hulk no longer functions, the 50 issue run closed all the Green Doors at the end.
Until someone else opens them again, ofc 🙄
Edit: Also this,
Only works because TOBA is possessing him. Regular Banner/Hulk can't do that.
