Hard as I have many, but if I had to choose one, it would be Sirius black simply because he was born into a evil family, but still turned out to be a loving, humble, loyal, brave and funny man.
<p>I agree with HorcruxHunter. Sirius Black was not only a father figure to Harry, He was almost like a father figure to me. I know that he is fictional and it sounds kind of odd, He just was always there for Harry when he needed him and that gave me comfort as a father would.</p>
