What does a "flat character" lack in a narrative?

A "flat character" is typically defined by a lack of depth and complexity. Such characters often exhibit one-dimensional traits and are not fully developed, meaning they do not possess the intricacies of feelings, thoughts, or motivations that more complex characters do. Flat characters usually embody a single characteristic or trait, making them predictable and static throughout the narrative.

In contrast, a round character, which is the opposite of a flat character, is more nuanced and multi-faceted. Round characters experience growth or change and are often influenced by their experiences, which adds to their realism and relatability. This depth is what makes a character compelling and enhances the narrative’s richness.

The other options do not capture the fundamental characteristic of a flat character as effectively. While motivation, presence, and conflict might vary in importance or representation, it is the lack of depth and complexity that most distinctly defines a flat character’s role in a story.
