What the author says about the character From this we can make some conclusions about the characters. They are typically the minor characters in the story. We can predict how the will act, and they will always act the same. They are typically the main characters in the story. We will not always be able to predict how a round character will act, and he or she will not always act the same.
Round characters seem more human and real compared to flat characters.
A static character does not change in the story. He is the same person in the end as he was in the beginning. Typically the main character will go through a change, and that is what makes the story interesting for us. Beware though, it is possible that the main character will not experience any change in the story.
