"You got a family?"
"Yes, and I will see them when I leave here. And you, Stark?"
"So you're a man who has everything, and nothing."
Tony Stark and Ho Yinsen[src]

Ho Yinsen was a renowned scientist and surgeon, hailing from the village of Gulmira. Yinsen was held captive, alongside Tony Stark, by the Ten Rings in Afghanistan, where he was charged with attending to Stark's medical needs when Stark was brought in injured from an explosive. Having lost his family to local terrorist activity, Yinsen helped Stark escape the cave, but willingly sacrificed himself in the process.


Early Life

Meeting Tony Stark

"Mr. Stark, Ho Yinsen."
"Ah, I finally met a man called 'Ho'."
―Ho Yinsen and Tony Stark[src]

Yinsen was an Afghan man from the small village of Gulmira. Eventually, he became a scientist after graduating from Cambridge University and started to work in Europe.[2]

Ho Yinsen introduces himself to Tony Stark

Ho Yinsen met Tony Stark on New Year's Eve in 1999 at Bern 2000 in Bern, Switzerland, after Stark delivered a lecture, while very drunk, on integrated circuits. Yinsen tried to introduce Stark and Maya Hansen to Dr. Wu, but Stark drunkenly brushed him off to focus his attention of Hansen.[3] However, Stark would not even remember this encounter when he met Yinsen again years later.[2]

In Captivity

Saving Tony Stark


Yinsen works as translator for the Ten Rings

"If you do this for them, he will let you go free."
"No he won't."
"No he won't."
―Ho Yinsen and Tony Stark[src]

Ten years later, Yinsen was captured by the Ten Rings, a terrorist group in Afghanistan. When the Ten Rings brought in Tony Stark, injured from an explosive used in their ambush, they charged Yinsen with keeping Stark alive. A skilled and resourceful field surgeon, Yinsen removed much of the shrapnel from Stark's body, and helped keep him alive long enough to build an electromagnet piece in his chest to keep the remaining shrapnel from entering his heart.[2]

Partners in Captivity

"What could it generate?"
"If my math is right, and it always is, three gigajoules per second."
"That could run your heart for 50 lifetimes!"
"Yeah. Or something big for 15 minutes."
―Ho Yinsen and Tony Stark[src]

Under captivity, Tony Stark and Yinsen were ordered by the Ten Rings to build a Jericho Missile similar to the one Stark demonstrated to the United States Armed Forces, or they would be killed. However, Stark refused and was tortured. Yinsen managed to motivate him and both men acknowledged that they would be murdered either way and instead focused on an escape plan. Stark revealed to Yinsen that he would use the parts that the Ten Rings gave them and build a weaponize suit of armor which he would use to kill the terrorists and return Yinsen to his family.[2]

Escape and Death

"This was always the plan, Stark."
"Come on, you're going to go see your family. Get up."
"My family is dead, I'm going to see them now Stark. It's okay, I want this... I want this. "
―Ho Yinsen and Tony Stark[src]

Yinsen helped Tony Stark keep the Iron Man Mark I suit he was making a secret from their captor, Raza, and assisted in its creation. When Tony asked about Yinsen's family, Yinsen merely noted, "I will see them when I leave this place." Yinsen also pointed out the damage wreaked upon the region by the terrorists, using Stark's own weapons, and asked if this is what he wished "the legacy of the great Tony Stark" to be.

Yinsen's gives Stark advice before dying

During the escape the terrorists were alerted to their plan, seeing there was not enough time to power up the suit, Yinsen took a gun and chased the terrorists away. He was shot and mortally wounded when he ran round a corner to be caught by dozens of terrorists. When Stark found Yinsen, mortally wounded, he reassured Stark, revealing that this had always been the plan as his family was dead and that he wished to be reunited with them. With his dying breath, Yinsen asked Stark not to waste his life.[2]
