Vladimir Propp's Narrative and Character Theory
Vladimir Propp founded the idea that a certain type of character was used in every narrative structure. He suggested that every narrative has 8 character types. These are:
1. The Villain - fights the hero. E.g. The Joker.
The villain usually wears dark colours and is not very attractive. This is to juxtapose between the hero and the villain.
3. The Helper - helps the hero on his task. E.g.. Robin (helps Batman). He helps by providing a physical presence in order to help Batman fight the villain.
4. The Princess - the character that needs to be rescued from the evil villain, marries the hero. E.g. Princess Fiona (from Shrek). Propp notes that the Princess is not clearly distinguished most of the time.
5. The Father - gives hero the task and identifies the false hero. Propp notes that the Father is also not clearly distinguished.
6. The Donor - prepares the hero for the task. E.g. Lucius Fox (from Batman Begins). He helps the hero by providing his with weapons etc. 
7. The Hero - reacts to the donor, completes the task (saves the day) and marries the princess. E.g. Superman.
The hero is usually dressed in colourful/ bright clothes and is normally attractive.
8. The False Hero - takes credit for the hero's actions and tries to marry the princess. E.g. Lord Farquaad (from Shrek).
