Cai Wang (181-244) was a Roaming general in Three Kingdoms China.
In his Dynasty Warriors 5 story, Cai Wang comes across Liu Bei attempting to escape from Cao Cao and the Wei army at Changban. He offers his services to Liu Bei in hopes of finding his purpose in life. Before Liu Bei accepts, Zhuge Liang intervenes and asks him to prove his loyalty by stalling Zhang Liao. Cai Wang, with the help of the various Shu generals, manages to stall Zhang Liao long enough so that Liu Bei escapes.
