Caspian X (books only). Gryffindor. He starts out very like Neville Longbottom. He's all tied up with feelings of insecurity and incompetence, but as he grows into his role, he gains courage, and, unfortunately, almost too much Gryffindor bravado and rashness that betrays him in his later years. But it's the same spirit that then asks to see 10 minutes of our world. And Aslan does agree.
Prince Caspian - in the book AND in the movie. He's the epitome of a fantasy prince - still learning, very good-hearted, courageous and merciful. I love when he comes to help Susan. Also Caspian is very handsome, and his accent is very attractive.
