Liu Shan

Liu Chan is the son of Liu Bei. During the Battle of Chang Ban, Liu Chan was left behind as the Shu forces fled Cao Cao's assault, but was saved by the valiant efforts of Zhao Yun. After his father's death, he became Emperor of Shu under the guidance of Zhuge Liang. After Zhuge Liang's death, he became corrupt and weak, and as a result, Shu was conquered by Wei.

To this day his childhood name, A Dou, is an idiom for an incompetent person.

Dynasty Warriors
During the majority of the Dynasty Warriors series, Liu Chan appears as an infant during the Battle of Chang Ban as a rare powerup. In Dynasty Warriors 5, his importance increases, as he takes over the Shu kingdom after Liu Bei's death. Due to this, he is left to defend Shu's land after an invasion from Wu at Bai Di Castle. A minor storyline is developed with those participating in the battle, as Liu Chan is resembled as weak and untrained. Further more, Zhuge Liang, Liu Bei's advisor, is busy at Wu Zhang Plains and is unable to help Liu Chan. The battle depends entirely on the next generation of warriors, including Jiang Wei and Liu Chan's wife Xing Cai. After the battle, Liu Chan vows to grow stronger. Xing Cai's ending scene shows Liu Chan training with her, and refusing to rest until he is strong enough to defend Shu.
