Favourite Harry Potter character.
This is a toughie, too, but although she is not a major character I have always had a special fondness for Lily Potter. Not only because she sacrificed herself for her son, but also because she was a tough and self-confident young woman at Hogwarts and raised her principles over the idea of being cool.
I also want to state here that I am absolutely no fan of the Snape-Lily-relationship. I loved the idea he was in love with her absolutely and give her high credit for sticking with him for such a long time, but I think he definitely didn't deserve her and was better off being with James - who is one of my other favourite characters. I loved how he made her a bit cheekier and she made him more morally inclined - my favourite couple.
Speaking of couples, I also really love Bill and Fleur as a couple and was happy when she returned. I think she is hilarious, stubborn and I love that she seems to be the only person not afraid of Mrs Weasley's temper.
