Becoming Iron Man Edit
Stark travelled to Afghanistan to supervise a field test for one of his weapons. During the demonstration, Stark tripped on a booby trap and a piece of shrapnel was lodged in his chest. The gravely injured Stark was taken captive by the revolutionary leader Wong-Chu, and was informed that within a week the shrapnel would penetrate his heart and kill him. Wong-Chu falsely promised Stark that if he built a powerful weapon, he would be allowed to undergo an operation to save his life. Even though Stark realized the tyrant was lying, he agreed, hoping to gain time and access to tools.
Stark was given access to a small laboratory with another captive, the renowned Asian physicist and Nobel Prize in Physics laureate Professor Ho Yinsen, whose work Stark admired in college. With Yinsen acting as his assistant, Stark designed and built an electrically powered suit of armor with a pacemaker-like device that enabled Stark's heart to keep beating after the shrapnel entered it, the armor was also equipped with heavy offensive weaponry.
Donning the suit, Stark connected it to its power source, an electrical generator. Lying on a table Stark was helpless until the suit was fully charged. In the least fortunate turn of events, Wong-Chu decided to check on his prisoners. Knowing that if they were found all of their work was for nothing, Yinsen decided to sacrifice his own life by distracting Wong-Chu, giving Stark the extra time he needed to charge the armored suit fully. As the Iron Man, Stark avenged Yinsen's death and scattered Wong-Chu's guerrilla troops. Then, still clad in his armor, which was necessary to keep his heart beating, Stark made his way to the jungle, trying to escape enemy territory.
