Is there a fictional character (movie or book) that you genuinely admire? Who and why?

— Not a real person depicted in a film or book, or used fictitiously.
— Not an actor playing the part of a historical or imaginary character.
— Not the author and creator of such a character.

Rather, an invented, imaginary character himself or herself, creation of a human mind: is there one that you admire? one that you look up to, one that inspires you, one that you wish to be like?

Who is that character, and what is there about him or her that you admire?
