The Deathly Hallows
Harry is the protagonist in the book, and his traits consist of: bravery, selflessness, outgoing, and strong minded. Outgoing can sometimes be a negative trait for him, because sometimes he really goes out of his way to help other people or try and protect them when he should be more worried about his safety. The traits are revealed through his actions against Lord Voldemort, and through how he acts around the ones he loves. The traits name him as the hero, and back up the nickname. He becomes the "good guy" in the story because he has these positive traits.
