"Peter"--whoever that is--is on his own. No MJ, No Ned, No Stark Technologies, No Tony, No Aunt May, No Uncle Ben. No past, no futre because Peter Parker is gone. Gone, not missed. Not dead, no legacy. Just Spider-man. Spider-man is all consuming. He is all Peter has to give, and so he is all Peter will give. He's just you're friendly neigborhood spiderman. Sad, empty, but spider-man nonetheless. Reflecting on what he's learned from Peter 2 and Peter 3, he paves a way forward.
All the Marvel characters aren't mine. There are not major OC's. Just Spiderman characters.
