I'm kinda hoping that the Vulture is one of the villains now.He could be in a nursery home where Aunt May is in SM4.He could have Cancer that makes his body look eaten away and he could have Alzeimers that makes him forget that he is a bitter evil man,and it makes him forget where he hid his flight suit.
And when Peter comes to visit Aunt May Adrian Toomes(Vulture) is with her and is a nice guy to her and to Peter.Peter learns that is use to be a scientist.
Toomes tells Peter that he has invented a suit that could cure Cancer and Alzeimers but the Alzeimers has made him forget where he has hid the suit at.
One day when Peter comes to visit Aunt May,Peter sees Toomes climbing out the window to kill himself.Peter jumps out the window with him and saves his life.
Toomes is shocked that Peter is spidey,but the Alzeimers makes Toomes forget that Peter is spidey after a couple of minutes.Peter tells Toomes that he can't kill himself.
Toomes tells Peter that he can''t live like this with the Cancer eating his body away and the Alzeimers eating his brain.And Peter tells him that he won't have too,that he is gonna help him find his suit.
Once Toomes gets his suit,Toomes is no longer the nice old guy that Peter and Aunt May knows,he is the evil guy that he use to be,he now remembers that Peter is spidey,and now he a threat to Peter as the Vulture.
Then instead of the Vulture dying at the end of the movie,Peter just takes the suit off of him and Toomes is back in the nursing home.And Toomes asks Peter if he has found his suit and Peter says no,that he is still looking for it.
And Aunt May could say to Peter when Toomes leaves the room,isn't he a nice man.
(The Vulture in his suit could be physically strong,he could give us cool areial battles,and his suit could have other types of weapons on them)
