I created a thread in the X-Boards about what the result of AvX could possibly (but not really) have on the relationship with the Avengers and X-Men.
~link to original thread ~
I thought I would ask you guys the same thing.
What would it take (what enemy would it take) for the X-Men and the Avengers to finally join up and become one super team?
What if the opposite happens? The AvX event could possibly be the straw that breaks the camel's back and lead to an all out Marvel war; Meta-Humans/Humans VS Mutants.
