Civil War

Captian America
fighting Iron Man

Recently, during a televised raid of a house containing select villains that had recently escaped from the super villain facility at Ryker's Island prison, the villain Nitro detonated himself and the resulting explosion killed the majority of the New Warriors, as well as the children at a nearby elementary school and the residents of the surrounding neighborhood. In the wake of the tragedy, Capitol Hill proposed the Superhuman Registration Act, a government movement to register all super-powered beings as living weapons of mass destruction, requiring all costumed heroes to unmask themselves before the government and subject themselves to federally mandated standards. This event triggered negative public opinion against the super heroes, in which sole blame from the public was placed. The international organization S.H.I.E.L.D. quickly propositioned Captain America to lead a squad of "cape killer" soldiers, trained to fight super-powered humans. He refused, and after being attacked by S.H.I.E.L.D.'s Anti-Superhuman Response Unit, went underground. Iron Man, however, was in full support of the act. After numerous skirmishes and a full out super hero battle in downtown New York, Iron Man emerged victorious; however his former ally Goliath (Bill Foster) had perished combating Iron Man's forces, and Captain America was assassinated on the steps of the courthouse after surrendering. In the wake of the war, Stark was offered the position as Director of S.H.I.E.L.D., and has accepted.

Tony’s armor eventually grew so sophisticated that it became sentient. At first Tony allowed the armor to do his job as Iron Man, but it became increasingly dangerous. It even committed murder, slaying the villain, Whiplash. When this occurred Tony had no choice but to face the armor. During the confrontation Tony went into cardiac arrest due to an injury he previously sustained battling Whiplash. Proving itself a hero, the armor ripped out its own components and created a cybernetic heart for it’s creator, sacrificing itself in the process.

Tony later revealed to the world that he was Iron Man. After this revelation he took the post as the President’s Secretary of Defense to monitor the use of his technology by the United States Military. He was subsequently forced to step down from the position when the Scarlet Witch went out of control and killed members of the Avengers, forcing them to disband. Tony publicly stated that he would no longer be Iron Man but that there would always be one. Though of course Tony continued to be Iron Man while maintaining a secret identity. More recently, Tony injected himself with a Nanotech virus that integrated many of his suits functions with his own biological systems. He has also been a member of a secret group known as the Illuminati, along with Professor Charles Xavier, Reed Richards, Blackagar Boltagon, Dr. Stephen Strange, and Namor for many years.
