Definition. A protagonist is the main character in a work of literature or movie. With many characters surrounding the protagonist, finding that main character can sometimes be confusing.
Excellent question. The hero is usually, but not necessarily the protagonist, and the protagonist doesn't have to be a hero.

The hero is the good guy, the person who's primarily responsible for saving the day.
