In the Ultimate line of comic books, Peter Parker was killed off in order to make way for the debut of Miles Morales (a character many fans would love to see on the big screen in the near future). While his demise wasn't handled quite as well as it should have been - it was Brian Michael Bendis writing - this story featured Peter Parker inadvertently getting shot after saving Captain America from an assassin. Despite being seriously injured, Spider-Man gave it his all in an epic battle against the Sinister Six outside his home with his family's lives on the line, ultimately defeating them but succumbing to his wounds. While this isn't a moment likely to make it into Phase 3, it's still a pretty damn perfect way of ending Peter Parker's story. With Marvel and Sony reportedly planning a trilogy of movies set around his high school years, do we really need to see Spider-Man reach college? Killing him off in Phase 4 would allow the focus to shift to focus to Miles, bringing not only more diversity to the superhero movie genre, but also ensuring that the character's stories remain in high school, a decision which may frustrated some comic book fans, but one which ensures that the franchise stands out from every other superhero property.
