My first multiparter Pokéfic was actually a comedy, a sort of parody of slash fics while lowkey being one itself. With Agapé (the previous version of Seiren), I had a more dramatic story, as I kind of wanted to try out a "serious" fic, even if the synopsis was crazy and there was still humor involved, but darker. With drama, I could get more invested in the events and characters and express my own feelings through the prose without feeling the need to be ecksdee funny the whole time. Even if the story was kinda crap in the end, I'd grown to really like writing the main character, Red, and continued to do so with a few heavier and grimmer oneshots.
As the character is who he is, that being a cultist, horror was sort of inherently involved since day one, but then with those oneshots I got actually interested in the genre and what it was like. I'd never actually watched horror movies as no one in my family did and I was kind of a scaredy cat, but then with my own whole crash into the world of mental health via a depression diagnosis, I became curious about how fear and the human mind in general worked. I'd already been interested in gore, body horror and surreal imagery before, so I did have a good link into horror I could build upon. With Hunter, Haunted, I finally started to call what I wrote horror and really played up the fear. However, HH is still definitely a drama and a character study - fear is just a really good way to push a character to their breaking points. I wouldn't dream of entirely draining a story of comedy, either, so there are definitely some darkly humorous tones involved.
On a whole other note, I have Pletora's Story and a longfic I'm planning in the same world. I read a bunch of PMD fiction and because I'm a furry I like worlds with a wide array of characters and settings and actually having an audience, I wanted to have something like that, too. I wanted to write something outside TPP, something that wasn't as restrictive with a barely-functioning world. I'm definitely a fan of the PMD games themselves, so I'm glad there's a fic community for that and one that still has so much variety.
Pletora's Story is kind of comfy but still dramatic, especially towards the end. I've had a great time writing it since I get to have multiple characters interacting with each other instead of just one guy moping about himself the whole time. Having an entire world you can do anything with is great for creativity - you can basically do anything, dip into any genres and try out all sorts of stuff. It's really rewarding.
