Heart of steel

As Tony Stark battles an Advanced Idea Mechanics (A.I.M.) siege engine, he reflects on how he became Iron Man following his capture six months earlier by A.I.M., who planned to force him to create weapons for them. To escape he teams up with Professor Gia-Bao Yinsen. The two build special iron suits to protect them on their way out of the A.I.M. facility.
