Ho Yinsen was a physicist, engineer and pacifist from the fictional nation of Timbetpal. Yinsen was captured in Vietnam by Wong-Chu before Tony Stark was also captured. Stark's US military convoy had tripped a land mine and he was injured with shrapnel that was slowly moving toward his heart. Yinsen builds a magnetic chest plate and affixes it to Stark's chest, preventing the shrapnel from reaching his heart. Wong-Chu then orders Yinsen and Stark to build weapons for him. Instead, Yinsen helps Stark secretly build the first Iron Man armor, which includes a device for Stark's heart to keep him alive. Yinsen sacrifices his life distracting Wong-Chu to buy time for Stark to power up his armor.

Twelve of Wong-Chu's former prisoners were disciples of Yinsen; one of these disciples (Sun-Tao) leads them to establish a quasi-religious cult called the Sons of Yinsen.
