Alazṓn is one of three stock characters in comedy of the theatre of ancient Greece. He is the opponent of the eirôn. The alazṓn is an impostor that sees himself as greater than he actually is. The senex iratus and the miles gloriosus are two types of alazṓn.

A stock character, also known as a character archetype, is a type of character in a narrative 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.
