A stock character is a character that relies heavily on cultural types or stereotypes for his or her personality, manner of speech, and other characteristics. In their most general form, stock characters are related to literary archetypes, but they are often more narrowly defined. Stock characters are a key component of genre, providing relationships and interactions that people familiar with the work's genre will recognize immediately. Stock characters make easy targets for parody, and the parody will likely exaggerate any stereotypes associated with these characters. round character是指比较丰富、复杂、多重，有许多矛盾特征的性格。 flat character则与此相对，是指比较纯粹、单一的性格。major character,主要角色minor character,次要角色
