Which term describes a character with no significant change throughout the narrative?

The term that describes a character with no significant change throughout the narrative is "static character." A static character remains fundamentally the same in terms of personality, beliefs, and values from the beginning to the end of the story. This lack of development can serve various purposes in the narrative, such as highlighting how other characters grow or remain affected by the events around them.

In contrast, a dynamic character undergoes significant internal change, often as a result of the plot's events or interactions with other characters. The protagonist, who is typically the central character or hero of the story, may be either dynamic or static, depending on the character's development. Similarly, an antagonist opposes the protagonist and can also be either dynamic or static. However, the primary characteristic of a static character is its unchanging nature throughout the narrative, making this term the correct choice.
