Over the years, Spider-Man has grown from a simple street-level Super-Hero taking on Electro and the Sandman to one of the Avengers strongest members. This is due , partly to the experience he's gained but also to the fact that he has teamed up with almost every hero imaginable. In the real world Spider-Man is one of the most famous and adored super-heroes in existence but in the comic books it's another story. Despite being in most major teams it is often pointed out that he isn't respected very much. For example, in The New Avengers comic book during Agamotto's attack when it is pointed out that Hawkeye possesses an emergency Avengers call where as Spider-Man does not. These little twists allow him to remain a funny super-hero as well as an important one.
Moving on to the subject now, In the not so recent Avengers : X-Sanction, Cable mentions that despite being a joke, Spider-Man goes down as the greatest hero in history. This has obvioulsy never been confirmed from what I have read (but please if you have inform me). Despite possibly being a teaser or a joke on the writers part the new Avengers Vs. X-Men issue 9 cover and description (Cover and Description below) seems to suggest that it is up to him to stop the Phoenix Five (Or four as of issue 8, sorry spoilers). What is your opinion ?
