1) Sadly not. As of this year I've begun making my own anime characters, as opposed to utilizing Pokemon content, so we'll see where that goes!
2) Pronouns
3) Flareon is a boy. Idk who he's attracted to though
4) (sorry, I don't understand this question)
5) Well distinguishing Eeveelutions from eachother is the eternal turmoil of this fandom, isn't it?
6) My DeviantArt uses characters both from this game's cast of characters, as well as outside this game's cast.
7) Anything in a game is 100% canon. Anywhere else I'd probably explicitly mention if it's canon
8) Hagen started as my persona/OC, then morphed into a character for this game's cast. He's male.
9) Sorry, as a personal motto I don't "confirm" anything that's not explicitly already in a game. I believe fictional worlds are made not just by developers, but their fanbases as well. I think Santa-Claus is an excellent example of this community-created world-building phenomenon (sorry kids), and I always love seeing how people's stories rub off on each other's ideas. Thus, I never force my canon on anyone else's story. My personal dream is to make a successful franchise that any creator can contribute to, kinda like Touhou Project or SCP Foundation.
