Mine were Snivilus, Dumblydor, and Harry.
DEATHLY HALLOWS SPOILERS!!!!!
Harry, because he was an amazingly brave man who never let fear, or anything stand in his way. He was astonishingly kind after all he had been through, and even though everything did get to him, he still acomplished his goals.
Snape, because he... well I have to admit I hated him through out the whole series until DH. But he proved that, however misled his intentions were, he was all in all a 'good guy'. He sacrificed himself to do Dumbledores bidding, for the woman he loved. He put his life on the line through and through, to make sure that he kept the boy he loathed so much safe, and alive. And although he said that it was for Lilly, in the end he let it show that he really had grown some tinest bit fond of Harry. He was brave, and honorable, and a darn good character.
I could go on for years about all of Dumbledores good points. He was wise, yet 'down to earth', he had been through alot in his childhood but he wanted to make amends, he fell down the wrong path, but sorely made up for it. He was inspiring and amazing, and I 'bout cried myself to death at the end of Half Blood Prince.
