Yinsen

Yinsen is the man who saved Tony Stark’s 
life by taking most of the shrapnel out of 
his heart and fitting an electro magnet 
powered by a car battery to prevent the 
rest penetrating his heart. He was held 
hostage by the Ten Rings in a cave with 
Stark to build weapons. However, he and 
Stark secretly built a suit of armor to make 
a getaway. When their plan was discovered 
too early, Yinsen bought time by chasing 
them with a sub-machine gun. However, 
he soon ran into over a dozen terrorists 
and he was fatally wounded. When Stark, 
now in armor, caught up, Yinsen asked 
him to leave him there, as he wished to 
die and be reunited with his family in the 
afterlife, but not before reminding Stark 
not to waste his life.
