Vladimir Propp analysed folk tales and from this he identified eight key character roles in these stories.
- the hero (good character)
- the villain (evil character)
- the donor (provider)
- the helper
- the father figure (caring character)
- the dispatcher
- the princess (the female that needs to be saved)
- the false hero
Propp argued that characters could fulfil more than one of these roles and that there can be more than one of each character type.
