After studying 100 fairytales, Vladimir Propp discovered that all characters fall into 7 broad types that can be found across different storytelling mediums. These 7 types are: the Hero, the Villain, the Donor, the Dispatcher, the False Hero, the Helper, and the Princess. Propp also identified typical scenes - the Struggle Scene, where the Hero battles the Villain, and the Recognition Scene, where the Hero is recognized or a false character is exposed. Propp's character and scene theories provide a framework for analyzing narrative structures across various storytelling forms.
