Iron Man

In modernizing the Iron Man's origin story, Tony Stark is not injured in a Vietnamese war zone, but in an act of industrial sabotage plotted by Justin Hammer and the Mandarin. Stark was wounded not by a chunk of shrapnel near his heart, but by slivers near his spine, Stark and Yinsen (whose first name is changed from Ho to Wellington) were held captive by the Mandarin, rather than Wong Chu. However the concept of the Iron Man armor keeping Stark alive was in Season 2 with getting Iron Man injured in his chest after taking a direct hit from a missile while attacking Hammer on his own property. He upgraded his armor in order to attempt to heal his chest.
