What do we call a character who remains unchanged throughout the story?

A character who remains unchanged throughout the story is referred to as a static character. This term highlights the character's lack of personal growth, transformation, or development as the plot progresses. Static characters often serve specific purposes within a narrative, such as providing contrast to dynamic characters who undergo significant change. Their consistency can help emphasize thematic elements or other characters’ transformations.

In contrast, a dynamic character experiences growth or change throughout the story, illustrating the impact of events or conflicts they encounter. A foil character is typically used to contrast with another character, enhancing particular traits or attributes through comparison. The antagonist usually opposes the main character or protagonist, often creating conflict in the story but may or may not undergo change. Understanding these distinctions helps in recognizing various character types and their roles in literature.
