As we know the amazing Spider-man is dead and people are pissed. The amount of people who used to buy it has lowered. My question is with them killing him off completely, is there anyway to bring him back and is their any plans on bringing him back?
Sure there is. All Ock did is put his memories inside Peter. He didn't insert his soul or anything like that so basically this is a Peter Parker who thinks he is Doc Ock. Because there was no magic involved its is logically impossible for Doc Ock to be in Peter's body. At the moment we are just following a brain-washed Peter Parker.
Hey, welcome to Comic Vine, guys.
As for your question: They have to. I think that was the idea in the bigining. I mean, imagine how many people will buy "The return of Peter Parker". The people that hate the idea of Superior Spiderman will pick it up, people that love the idea will pick it up, and some people that aren't reading it, might just start getting the series. It's the perfect move.
