Iron Man, the Marvel Universe's most popular character, is one of the world's richest men and a genius inventor. A child prodigy, Stark studied electrical engineering and physics at MIT. He later founded Stark Industries, a power systems engineering firm.
He's also a very self-driven person, pushing his brains to their limit and finding motivation in a variety of subjects that interest him. This often results in a fast learning curve that he finds easy to master.
As a result, he has an extensive knowledge of everything under the sun that could be considered an engineer's realm, including electronics and engines. This allows him to design the AI and tons of software that is incorporated into all his suits' HUDs and Arc Reactors for their eco-friendly power sources.
Tony Stark is a Turbulent Commander (ENTJ-T) personality, which means he enjoys being the center of attention and doing his thing with the biggest audience possible. This is evident in his tendency to goad powerful people, hop in his race car, and test out his latest inventions.
He is a risk taker, always trying new things, and his recklessness can get him into trouble. He doesn't have much respect for authority because he knows he's right almost every time.
He's not afraid to put his money where his mouth is when it comes to superheroes, spending millions on a suit that allows him to fly around the world and battle villains. He also funds various peacekeeping organizations and superhero teams, such as S.H.I.E.L.D. and the Avengers, which he is director of. He also has an enormous amount of wealth, and he's willing to spend it on luxury items like cars and houses.
