So what's Iron Man's story? From the above posts it sounds like he was forced to create a weapon and then he became that weapon?
Tony Stark was brilliant. A Billionaire Weapons Designer and Dealer, but also a party boy and an alcoholic.
In the movie it looks like he is giving the US Army a demonstration of some weapons, and then they are transporting him somewhere. Some terrorists attack the army convoy he's in, and kidnap him for their Warlord who wants him to build weapons for them.
Unfortunately he's seriously injured in the fight when they grab him, and a piece of shrapnel is lodged in his heart.
He builds some sort of device in his chest that keeps him alive, some sort of advanced pacemaker kinda thing.
He and another captive are supposed to build weapons for the Warlord, but instead they work together to build a suit of powered armor to escape with.
He "opens up a can" on the terrorists and the warlord, busting to freedom as Iron Man.
This ends up being kind of a life changing experience for him and he struggles to be a better person, while still having problems with alcohol and stuff.
He makes other Iron Man suits and becomes the Hero known as Iron Man!
