What began with a flash of naiveté, ended with the deaths of hundreds. In the quiet suburban town of Stamford, Connecticut, reality TV stars and young heroes the New Warriors staged an attack on a group of villains they believed they could easily defeat. But with the battle almost won for the heroes, the villainous Nitro unleashed a massive explosion, killing hundreds of innocent men, women and children, along with nearly everyone engaged in the melee.

With that incident as the igniting spark, everything in the U.S. changed. Super hero regulation and Registration swept through the government and sides were quickly drawn.

Iron Man acted as the figurehead for the government, S.H.I.E.L.D. and Registration. Hoping to persuade wayward heroes and misguided villains into joining the cause, Iron Man was branded a fascist and traitor by some. But he believed that he was working for the greater good, attempting to prevent another Stamford incident and to hopefully make the world a safer place.

Unfortunately for Iron Man, Captain America didn't see it that way. Viewing Registration as a crushing blow to civil liberties, the fighting, flag-wearing symbol of America led a smaller, underground resistance movement. Cap's anti-Registration forces fought an uphill battle against the collective forces of an army of super heroes, the government and S.H.I.E.L.D., but it was a war they truly believed in,

There have been unorthodox recruitments and bold maneuvers. And while Civil War has already vastly affected the status quo, the road ahead looks to forever change the landscape of the Marvel U.
