The elderly martial arts master is a mentor/teacher in fiction, especially Wuxia, Chanbara, and other martial arts films. Typically East Asian, he is a near-invincible master of the martial arts, despite being advanced in age and presumably having a decrease in physical strength. Often he possesses the rank of Sensei (or teacher) and is referred to as such by his student. The elderly master most often teaches either generic kung fu or an exotic style specific to the fictional period (see List of fictional martial arts). During the films, the master often becomes close with their student, with the master becoming a guardian figure to the trainee, who is, in turn, looked upon as a son or daughter. Usually, when the master is captured or killed, or an iconic portrait of the deceased master has been desecrated by some villains, the hero will take it upon themselves to rescue or avenge their master.
A typical elderly sensei spends most of his time meditating in a dojo while deep in thought. The master is typically a serene, calm, sober and reserved old man. He represents the maturity and self-contentment that comes with age, along with the quiet confidence that comes with experience—both of life in general and of the skills and also the ideals and values that he has inherited from the martial arts. To him, his martial art is not just a way to beat people up or to act tough, it is—in keeping with the values and ideals generally attached to and associated with the martial arts by the Oriental societies—more a means to positively developing one's personality, way of living, to cultivate values such as respect, patience, self-control, discipline and the whole lot. The master is polite towards everyone, even the mischief makers who would misbehave with him sometime in the course of the movie. He always tries to verbally prevent mischief makers or the rival martial artist (who is often young and arrogant and sees the martial arts only as a means to act tough and bully people) for as long as he can, and that too politely. Only when he is forced to use his skills and left with no option, he shows how the mischief makers are no match for him—thereby demonstrating how politeness should not be mistaken for weakness. These are shown, for example, by Mr. Miyagi in the Karate Kid series, or the Janitor in the new Karate Kid, or Yoda of Star Wars.
