I gravitate toward a few character types in my writing. Probably the most common, and the one that other people have commented on most often, is competent women. My favorite character list is riddled with women that fit this mold (Paine, Yuna, Fran, Aveline, Natasha Romanoff, Peggy Carter, Susan Ivanova, C.J. Cregg (whom I've never written, but someday, who knows)...) and when I have to create a one-off OC for a fic, there's a very good chance that she'll be very similar. Most of my female Wardens, too, as is my first Inquisitor, and I tend to push my female Hawkes in this direction as well (which is why I don't really play along with the dominant fandom image of Hawke as a Jo Shmo who just happens to be in the right/wrong place at the right/wrong time). I like writing about women, and I like writing about people who, for the most part, know what they're doing, so this is a natural intersection.
Another character I enjoy writing is typified by Alstair Thierin and Steve Rogers: the guy with a strong sense of right and wrong, cares about people and wants to do what he can to help, snarky sense of humor when he lets it show, a bit too earnest, a bit too naive, commits to a course of action and sees it through. I say guy, but Yuna fits this category, too, in a lot of ways. I like competence in a male character as well, although it's not a bulletproof kink in quite the same way.
I also like characters with secret pasts: Auron, Balthier, Paine again. I like digging out the details, figuring out how they might be seeing a situation based on what they know that we don't.
I feel like I ought to have more to say on this topic, but I'm blanking for now. Ask me again later, I might come up with a dozen more. :)
