Thirty Days of Fandom Writing: Day Three

For each of the fandoms from day two, what were your favorite characters to write?

Kara Thrace. :D

No, really. Whatever fandom I'm writing in, Kara is my girl. She was in the Firefly crossover and the two Buffy crossovers.  The three-sentence fics don't count, because...well, they just don't. Even when I'm writing original fiction, Kara's influencing it somehow.
