Reading Supernatural fanfics, I got curious about why so many of the stories are M/M. Is it just a popular genre?

But once I considered what M/F pairings I'd make from these characters, it quickly became clear that there just aren't that many women characters in the series. By number there are a lot, but by character development there are very few.

So when fans pair off their favorite characters, it's just more likely to be two men.

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

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.

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 new characters, he responds to new 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.
