Flat character

A flat character is the one that doesn't develop or remains unchanged in a story. It has no complexity and whose personality is presented with a single feature.

Flat characters are sometimes used as background elements and add no relevancy to the main story.

It should be a flat character because those tend to generally be the irrelevant characters in a story.
