Propp's theories are very male-oriented. Are all stories about hero/ villain struggles 

1.	The villain (struggles against the hero) 
    The villain. The villain performs the villainy, struggles with the hero, 
    and pursues him/her.

2.	The donor (prepares the hero or gives the hero some magical object) 

3.	The (magical) helper (helps the hero in the quest) 
    The helper. The helper may undo the misfortune or lack, rescue the hero from pursuit, and transfigure the hero.

4.	The princess (person the hero marries, often sought for during the narrative) 

5.	Her father 

6.	The dispatcher (character who makes the lack known and sends the hero off) 

7.	The hero or victim/ seeker hero, reacts to the donor, weds the princess 
    The hero. The hero performs the departure and engages with the villain. 
     Oddly, the conflicts are represented in the villain's domain in this analysis.

8.	false hero/ anti-hero/ usurper - (takes credit for the hero?s actions/ tries to marry the princess) 
    The false hero. The false hero appears in some stories, engages in some 
    of the activities of the hero, and has a special function of presenting false claims.

A protagonist  (hero/heroine)
is the main character (the
central or primary personal figure) of a literary, theatrical,
cinematic, or musical narrative, around whom the events of the
narrative's plot revolve and with whom the audience is intended to
share the most empathy. In the theatre of Ancient Greece, three
actors played all of the main dramatic roles in a tragedy; the
leading role was played by the protagonist, while the other roles
were played by deuteragonist and the tritagonist.

An antagonist  (villian) is a character, group of characters, or an institution,
that represents the opposition against which the protagonist must
contend. In other words, 'A person, or a group of people who oppose
the main character, or the main characters.'[2] In the classic style
of story where in the action consists of a hero fighting a villain,
the two can be regarded as protagonist and antagonist, respectively.[3]
The antagonist may also represent a major threat or obstacle to the
main character by their very existence, without necessarily actively
targeting him or her.
