Ho Yinsen Birth Earth Race Human Affiliated with Ten Rings
Portrayed by Shaun Toub
Ho Yinsen was a doctor and engineer from a small village in Afghanistan called Gulmira. He was later captured by the local branch of an international terrorist group called the "Ten Rings." While in captivity, he helped save Tony Stark from dying by building a car battery-powered magnet that would prevent the lethal shrapnel buried in Tony from killing him. He would then help build the Mark I, and ultimately sacrificed himself in order to buy Stark more time.
