Anna from Frozen! She's one of my favorite new Disney characters. She, like Rapunzel, lead such an isolated life. They could have made her painfully naive, and instead she comes across more as genuinely excited by life and ready to launch head first into everything. She's sweet, but also smart and sassy. Sure, she makes mistakes, but she does so because she's so utterly without malice. Anna is so obviously in need of someone like Elsa, who needs Anna most of all. It's a beautiful story of sisters and love.
