Answer:
Well, there are static characters and there are dynamic characters. Static characters are characters that remain unchanged throughout the story. One example of this would be Lenny from Steinbeck's novel of Mice and Men. A dynamic character is one that undergoes a significant change. One instance would be any character from a Buldungs Roman novel such as Jane Eyre or Their Eyes Were Watching God.
Other types of characters are protagonists and antagonists. Protagonists are generally, but not ALWAYS the main character. They are meant to bring about some good and are met with the opposition of an antagonist. An example of this would be in Treasure Island. Jim Hawkins is considered the protagonist, while Long John Silver is the antagonist.
Among characters are background characters, heroes, fill characters, and complementary characters. Characters are diverse and come in many forms.
