The Supernatural fanfics have a lot of M/M romance stories, and I think that is not just because there are a lot of writers and readers for M/M. When I considered which M/F pairs I'd make from these characters, it became clear that there are not a lot of female characters to work with when you take into account the amount of character development they get. The fan-favorites are simply more likely to be men than women.

Or: Does misogyny lead to homosexuality? If you mostly include women characters when they can be combination sexual-interest-and-sad-death-story, does that leave the fans with a collection of all-men characters to mix and match?

Data gathering to support or disprove this theory: I am making an analysis of each character's development in the series.

I'm looking for back story, character traits, relationships, and character arcs.
• +1 point for a fact
• +3 points for a characteristic or trait
• +5 points for a relationship formed or changed
I'll try to only give points the first time a fact or trait comes up, not every time.

This will be chock-full of spoilers, so the reasons for the points start off collapsed/closed.

The dark blue points are compressed to 10x,
so Dean and Sam don't run right off the page.
Hover over the bar to read the total points value.

I am refining my theory. The women characters are well-characterized when they are present. But they don't get as much screen time as the men characters, so they don't get built up.

For instance, Bobby is always around. He's in the story across many episodes, he's mentioned even when he's off-screen, he interacts with many other charters, he responds to many different situations. When writing a fanfic, you know you can always include Bobby, and you have a good idea how to include him.

But Madison only appeared in one episode and got maybe one mention after that. You'd only include her in a fic if you specifically wanted to write a fic about Madison. And you'd need to invent most of her character yourself.
