Yao Wu (Earth-8998)

"The Mandarin, the bombings, all these disasters...you don't need to go through all of this alone, Tony... Not if you open yourself to help."

- - Doctor Yao Wu

Doctor Yao Wu is a Chinese cardiologist specialized on both Eastern and Western medicine, as well as possessing a in-depth knowledge of Chinese culture. He is an old friend and acquaintance of Tony Stark, who, after the Battle of New York, helped Tony to stabilize the Arc Reactor on his chest.

Early Life
Yao Wu was born in China, on April 5th, 1956. He became a expert surgeon and cardiologist upon his graduation at the University of Science and Technology of China. He married and had three children.

On the New Yeark's Eve of 1999, Doctor Wu accompanied Doctor Ho Yinsen to a conference in Bern, Switzerland, where Stark Industries CEO Tony Stark was giving a lecture on integrated circuits, albeit very drunk. Yinsen then introduced Chen to Stark and Doctor Maya Hansen, and they shook hands, but Tony would only mock both of them, as he jokingly said Yao would have to perform a heart surgery after Stark and Hansen had sex together, much to the Doctor's discomfort. However, after the incident, Wu would manage to contact Stark, and they started a friendship.

Mandarin's War
Years later, on 2012, after Tony Stark threatened the Mandarin so the whole world would see, Doctor Wu called on his friend's house and advised him to take caution with his actions, also stating he should count on his friends, assuring to Tony he wasn't alone.

Later on, Doctor Lu was called on to perform a surgery that would fix Stark's Arc Reactor, which, poisoned, was making him slowly perish. Alongside his assistant, Doctor Fan Cho, they were successful, and Stark was cured.
