Iron Man Armor: Mark I

The Mark I is the suit Tony Stark built in a cave out of whatever was lying around. Held by the Ten Rings and put to work assembling a Jericho missile for them, he assembled something else alongside it from scrap metal, machine parts and pieces of the missiles themselves, with Ho Yinsen working beside him. What came out is heavy, crude and effective. Layers of salvaged missile casing leave the shell close to impervious to small arms, the frame moves a man who has been underground for months faster and harder than he has any business moving, and the armament is what a workshop of stolen ordnance produces: a flamethrower at each wrist, missiles on the arms and one single-shot round hidden in the left. It cannot hold a flight, only a short rocket-assisted jump.
