One of the key aspects of Tony’s intelligence and success in the world of business is that he is a futurist, always thinking about how the events of today will affect the events of next year. He is smart enough to correctly predict the major events of the future, and he does his best to combat the bad things and help along the good. This was an essential facet of his rationale during Marvel’s Civil War event. Tony was able to anticipate the conflict years before it happened, and he saw that the benefits of joining with the government outweighed the consequences.
Not unlike his good friend Captain America, Tony has an strong sense of willpower. If he seizes upon an idea, he won’t stop until he sees it through. He is more practical and less idealistic than Cap, but he is just as determined when he has a goal.
However, Tony does have his weaknesses. He often makes his decisions on the basis of what is best for him and his livelihood, and that drives him. This selfish streak is tempered by his sense of responsibility and a newfound humility, but it runs deep within him.
