I had a crush on Trillian from Hitch-hiker's the first read through. Now, not so much. Thought Fenchurch was too plastic to bother crushing.
Most of my crushes are TV characters (as opposed to the actresses, who are good looking, but I don't know enough about their real personalities to crush), so I guess that still counts as fictional crushes...
Let's start with Joss Whedon's characters... virtually all the females. Buffy, then Willow, then Anya, then Dawn (honest, she's my age, so it's alright!), then Fred. Never had a thing for Joyce or Cordelia - both attractive in their own way, but I didn't like their personalities much. Well-written, but not for me.
Sabrina the teenage witch... okay, that's mostly physical, the character was kind of annoying.
The chick from the Matrix, in the first movie at least.
Boy, I could go on and on, and you know it's all going to be SF/F characters!
