It should come as no surprise to you that I would choose literary characters for this one. And if you should say "Literary characters don't count: they're not real!" then you are hereby banned from my list of friends. I prefer book characters to real people: you can believe in them, there are no consequences for hating or loving them, and their feelings will never be hurt by your speaking your mind about who they are and what they stand for (although this may spark discord and heated debate among the people you know that actually breathe).
My first choice is, as always, Rosalind from Shakespeare's As You Like It. This is, by far, my favorite Shakespeare play, and the following is the best movie adaptation I've ever seen (probably the only movie adaptation, come to think of it). Either way, Rosalind is my heroine among heroines. She's clever, witty, and beautiful: incredibly feeling and emotional, somehow manages to get herself into the silliest scrapes, and just as equally amazingly gets herself out. And all with the greatest sense of humor and honor.
