At a New Year's Eve party in 1999, Tony Stark meets scientist Maya Hansen, the inventor of experimental regenerative treatment Extremis that allows recovery from crippling injuries. Disabled scientist Aldrich Killian offers them a place in his company Advanced Idea Mechanics, but Stark rejects him. In 2013, Stark is having panic attacks due to his experiences during the alien invasion and subsequent Battle of New York. Restless, he has built dozens of Iron Man suits, creating friction with his girlfriend Pepper Potts.
