I'm going through Game of Thrones at the moment. I think this is a narrative that has a very distinct like of Mary Sues in it. Martin really does take time to express a characters vices. Even the typical Lawful Good Eddard Stark has a past he doesn't like to talk about regarding his bastard son Jon. And funnily enough, it's Jon I want to talk about, as he is probably the closest to a Mary Sue GoT has. He's the troubled outcast with a heart of gold. Great in battle, (usually) gentle in spirit, loved by all his family despite him being not a true born (except for Catelyn, Eddard's wife). He even refused to have sex with a prostitute because he was too afraid of getting her pregnant and having a bastard child of his own, and thus make that child go through the same rejection he did. So yeah, Jon Snow is my contribution.
