Favorite fantasy character, hmmmmm...I would have to say Artemis Entreri from R.A. Salvatore's Dark Elf series (Yes! I confess! I like him even more than Drizzt!), the White Witch from "The Lion, The Witch, and The Wardrobe" (Chronicals of Narnia) and the Cheshire Cat (although I don't know if Alice's Adventures in WonderLand constitutes "fantasy")
