Marvel Comics superhero, also known as Iron Man. He is a
billionaire who owns the company Stark Industries, founded by his father, Howard Stark. When both of his parents died at a young age, he took over the company.
Incredibly selfish and egotistical, and generally not liked by others, as he has many character flaws he doesn't recognize as flaws.
One day he is in
Afghanistan presenting his latest missile technology to the US army, when he is kidnapped by terrorist
organization, the Ten Rings, to whom Stark's company has been illegally dealing weapons to without his knowledge. They demand he builds them a missile identical to the one he presented earlier, in exchange for his freedom. Instead, he builds a robotic supersuit with the help of Ho Yinsen, a scientist also being held captive. Yinsen sacrifices his life to allow Stark to escape captivity, motivating Stark to construct a sleeker version of the supersuit upon returning home, and taking
responsibility for his (and his company's) actions tracking down all illegal shipping manifests that took place through his company, and destroying them. (story varies slightly based on the comic)
