Well, my favourite character is not one in particular but I voted for San because I love Princess Mononoke but also I like Howl (of course!), Ashitaka, Mei and Satsuki (cute), Nausicaa, Porco......mmmmmmmm......definitely, I think everyone likes me LOL!
Nausicaa, most definitely, although I'm thinking of the manga more than the film. I found it pretty rightful that the Worm Handlers worshipped her as a god later in the story. She's quite deserving of it. Her love and respect towards life is amazing.
