Final answer:
A static character remains consistent throughout a story and does not influence its outcome, offering a benchmark against which the evolution of dynamic characters can be measured.
Step-by-step explanation:
A character that will not change a story's outcome is called a static character. These characters remain consistent in their behaviors and attitudes throughout the story, providing a contrast to dynamic characters who experience significant internal change. Static characters, like Mrs. Micawber in Charles Dickens' David Copperfield, who famously declares 'I will never desert Mr Micawber' and remains true to her word, serve as a reference point to highlight the changes in other characters.
