Well it is hard to decide. I'm such a fan that I got Star Wars Trivia for the entire saga for Christmas, <sigh, haven't gotten to play it yet>. But my all time favorite has to be Han Solo, his wit and ruffian attitude is phenomenal. My aol greeting is "laugh it up, Fuzzball." We all know Chewwy could "use a good kiss," so there you have it.
Second would be Anakin. I have great empathy for him now. His torment is tremendous, still cried during Episode III.
It's always good to spread your wings and fly high!
