"The armored body reaches its apogee in Iron Man, another non-superpowered superhero. Created by writers Stan Lee and Larry Lieber and artists Don Heck and Jack Kirby, he made his first appearance in Tales of Suspense No. 39, March 1963. The product of the Cold War, specifically the Vietnam War, Iron Man's costume, like that of so many superheroes, is linked directly to his origin. Tony Stark, munitions manufacturer, visits Vietnam to oversee experiments of his miniaturized transistors, which he tells a general are 'capable of solving your problem in Vietnam.' A booby trap, which lodges pieces of shrapnel near his heart, results in his capture by the Viet Cong. On learning that he is an inventor, they trick him into designing weapons in exchange for a false promise to remove the shrapnel. Instead, he builds a suit of armor with a life-sustaining pacemaker from scrap iron. Over the next few issues, the armor is redesigned, initially as a golden version of the original and then as the red-and-gold armor that has become his trademark. Transforming Tony Stark into a machine, it quite literally embodies his power. Like Batman, Iron Man serves as an effective metaphor for defensive paranoia, for our fears about human weaknesses, limitations, and vulnerabilities. At the same time, he acts as a metaphor for our social reality, in which the distance between the body and technology is fast disappearing."
