During the Civil War and the battle between the forces of Captain America and Iron Man in the Negative Zone, things start to go differently. Black Panther, trying to open a portal back to the real world, discovers that a self-destruct system has been triggered. He stays to buy time while Cloak tries to draw as many people as possible into his cape. But he isn’t fast enough to close the portal: the destruction of the inter-dimensional prison lays waste to most of New York. With Captain American and Iron Man each believing that the destruction was on the orders of the other one, they refuse to be reconciled….
Now, many years later, the United States is divided into two nations: to the East is The Iron where law and order reigns, exemplified by Ms Marvel coming upon a girl trying out powers of flight for the first time, lecturing her on safety and responsibility and making sure she is schooled in the use of her newfound powers. To the West is The Blue, a libertarian state full of self-governing communities, where Stature discovers a kid with blast powers and encourages him to consider using them for something good before wandering off.
Now, Miriam Sharpe, mother of a child killed in the Stamford Incident, is arranging a peace conference between Tony Stark and Steve Rogers, optimistic that reconciliation can be achieved. Steve arrives with his aide Peter Parker, Tony with She-Hulk. As they meet outside the conference room in neutral territory, Tony has brought Mary Jane Watson-Parker and her daughter Maybelle for a reunion with Peter. Meeting at the conference table, with Miriam to act as mediator, Tony reveals that The Iron is becoming over-populated and he wants a land grant from The Blue; in return Steve’s nation will be recognized by other countries as now it is considered a rogue state. The talk quickly turns bitter as old animosities and mistrust come to the fore. Suddenly a sniper’s bullet pierces the window, fatally striking Miriam Sharpe. Steve calls Peter to search for the assassin but Peter with his mechanical wings can only recover the rifle. The truce broken, Steve determines that the shot was really meant for him—and that Tony must know who fired it. The two leaders part ways and another war seems in the offing….
