I love the "Q" idea!
He could fly around on a hovering pizza box (this would settle the Joe Q "Pizza controversy"), and he could use continuity bombs! THey are a slight variation on the "Retcon bombs" used by the Hobgoblin from the future, except these insert false history into Spider-Man's life and causes everyone to behave out of character! Spider-Man himself could become weak-minded and indecisive when around the "Q", so he calls in help from Reed Richards, who is acting out of character himself, and, together they banish him to a parallel dimension which has sprung up due to all his tampering with time. Here....all his creations from the wreckless use of his "Continuity Bombs" haunt him and torment him for all eternity....and among the torment, he meets another who will eventually aide him in his escape from the horrible realm...
