- Can the Incredible Hulk die? 12 answers
If you have seen 'avengers:age of ultron' there is a scene where scarlette witch shows stark what will happen in the future if he takes the scepter but at the top of the steps where all the avengers lay dead is the hulk but my intensions were that the hulk couldnt die as in the first avengers fury tells agent romanoff to escort dr banner to his room and then he says something about the cell was there just incase and then banner turns and says 'what incase you needed to kill me? Well you cant, i know because i've tried' anyone have any suggestions on this??
