type 3 stock

A stock character, also known as a character archetype, is a type of character in a narrative (e.g. a novel, play, television show, or film) whom audiences recognize across many narratives or as part of a storytelling tradition or convention. There is a wide range of stock characters, covering people of various ages, social classes and demeanors. They are archetypal characters distinguished by their simplification and flatness. As a result, they tend to be easy targets for parody and to be criticized as clichés. The presence of a particular array of stock characters is a key component of many genres, and they often help to identify a genre or subgenre. For example, a story with the stock characters of a knight-errant and a witch is probably a fairy tale or fantasy.
There are several purposes to using stock characters. Stock characters are a time- and effort-saving shortcut for story creators, as authors can populate their tale with existing well-known character types. Another benefit is that stock characters help to move the story along more efficiently, by allowing the audience to already understand the character and their motivations. Furthermore, stock characters can be used to build an audience's expectations and, in some cases, they can also enhance narrative elements like suspense, irony, or plot twists if those expectations end up subverted.
