He also concluded that all the characters in tales could be resolved into 7 abstract character functions

He also concluded that all the characters in tales could be resolved into 7 abstract character functions

1. The villain — an evil character that creates struggles for the hero.
2. The dispatcher — any character who illustrates the need for the hero's quest and sends the hero off. This often overlaps with the princess's father.
3. The helper — a typically magical entity that comes to help the hero in their quest.
4. The princess or prize, and often her father — the hero deserves her throughout the story but is unable to marry her as a consequence of some evil or injustice, perhaps the work of the villain. The hero's journey is often ended when he marries the princess, which constitutes the villain's defeat.
5. The donor — a character that prepares the hero or gives the hero some magical object, sometimes after testing them.
6. The hero — the character who reacts to the dispatcher and donor characters, thwarts the villain, resolves any lacking or wronghoods and weds the princess.
7. The false hero — a Miles Gloriosus figure who takes credit for the hero's actions or tries to marry the princess.^[4]

Most popular fairy tales have very little magic in them. They are way too short to use all the functions and their sequences identified by Propp.
