In Romance of the Three Kingdoms
It is unknown when Zhao Yun is born, but estimations point that he should be born at around late 160s, early 170s. He initially joined Gongsun Zan, a warlord, at around 191, but he soon turned to Liu Bei at around 200 (after Zhao Yun attended his brother's funeral) because they were close during Liu's tenure in Gongsun Zan's side.
From then on, Zhao served Shu on many battles, with the Battle of Changban probably being the most famous. It was said that Zhao Yun went to save Liu Bei's infant son, Liu Chan, and he had to fight all the way back to Liu Bei's camp. But in other battles, Zhao Yun was also considered to be very effective and earned a lot of titles, such as General of the Standard, and General that Conquers the South. He was also part of the Five Tiger Generals of Shu, which included himself, Guan Yu, Zhang Fei, Ma Chao and Huang Zhong. Even after Liu Bei's death in 223, Zhao Yun continued to a force in the army. He was also a key general during Zhuge Liang's Northern Expeditions (although the campaigns failed).
Zhao Yun died of illness in 229, and Shu deeply mourned his passing. Liu Chan, who was then emperor and who Zhao saved in Changban, gave him honors even after Zhao died. He was survived by his sons, Zhao Tong and Zhao Guang, who both became Shu officers.
In Video Games
Zhao Yun's most notably part comes from the Dynasty Warriors series, in which he appeared in every single release and is the unofficial Poster Boy of the mainstream franchise. He is depicted to be honorable, fearless and a competent general (much like Samurai Warriors' poster boy, Yukimura Sanada). Despite his changes in uniform, Zhao Yun uses a spear in the main games and the spinoffs.
He also appeared in the Romance of the Three Kingdoms series.
