Every character lives their own story, but within a story not all characters are equal.
Minor & Placeholder Characters
These are the characters that make up most of the people in the world of the story. A minor character performs one or two significant actions, and then fades away. They don’t change or evolve, they simply exist. They are often eccentric or exaggerated, but they lack the complexity of a main or major character. The audience is entertained, but doesn’t miss a minor character when they leave.
