Harry Potter

After his parents were killed by the most feared wizard of all time, Harry was sent to live with his mother's sister, Petunia Dursley, along with her husband, Vernon, and son, Dudley. No family could possibly be worse: they don't encourage magic, and kept Harry's future from him as a child, up until his eleventh birthday when a strange and mysterious giant tells him his past. This 'giant' later becomes one of Harry's closest friends and professors at school.

Along with his two friends -- Ron Weasley, who is one of seven children, who lives in a petite house and his father earns minimum wage; and Hermione Granger, who’s Muggle born (her parents aren’t magical), and the daughter of two dentists -- Harry is able to survive the school years at Hogwarts School of Witchcraft and Wizardry.

I think Harry Potter is a hero because he shows great bravery. He’s able to stand up to students, as well as the most feared wizard, and even greasy-haired professors. Before himself, Harry thinks of the other people around him, worrying about their safety and the environment that they are in.

Mostly, overall, he's a hero because he's a teenager. Most people view heroes as adults who have accomplished hundreds of things in their lives, but Harry, who's still rather on the innocent side, brings a whole new vision of a HERO.
