Deuteragonist Definition & Meaning
A deuteragonist is the second-most important character (a main character), working closely with the protagonist. They aren’t the main focus but often have their own character arc. They can push the plot forward by helping the protagonist, clashing with them, or showing a different perspective. This makes the story feel richer by adding variety to the characters’ goals and challenges.
Deuteragonist Examples from Movies
Let’s have a look at some good examples of deuteragonists from famous movies.
Note that a movie can have more than one deuteragonist. That’s because a deuteragonist is a main character – a supporting role, if you like – to the protagonist.
