I'd say Hermione Granger from Harry Potter because she's smart and brave. Also, Katniss Everdeen from The Hunger Games for her determination. And maybe Belle from Beauty and the Beast for her kindness and love for books.
I think I'd be like Frodo from The Lord of the Rings because of his perseverance in the face of great challenges. Then there's Arya Stark from Game of Thrones for her independence and adaptability. And, Alice from Alice in Wonderland for her curiosity and sense of adventure.
