Harry James Potter (born July 31, 1980) is a fictional character and the protagonist of J. K. Rowling's Harry Potter series.
He is the only child of James and Lily Potter. Harry inherited his mother's bright green eyes and his father's perpetually untidy jet-black hair. In his younger years, Harry is described as being small and skinny for his age. The most intriguing of his physical characteristics is a long thin scar on his forehead shaped like a bolt of lightning. This is the only physical mark Harry bears that attests to his horrific and traumatic past. It was left by a curse cast by Lord Voldemort on October 31, 1981, which killed his parents and destroyed their home.
Harry attends Hogwarts School of Witchcraft and Wizardry with his best friends Ron Weasley and Hermione Granger. He is famous throughout the wizarding world for being the only known person to have survived the Killing Curse and subsequently causing Lord Voldemort's downfall. However his death was only assumed by the witches and wizards of the magical world and his consistant remergence into the magical world in varying forms fuels much of Harry's Adventures at Hogwarts.
Daniel Radcliffe has portrayed the character in all four Harry Potter films, and will appear in the next film, Harry Potter and the Order of the Phoenix, due out July 13, 2007.
Hair colour: Black
Eye colour: Emerald green, almond-shaped
Allegiance: Dumbledore's Army, Order of the Phoenix
Harry is famous in the wizarding world for his encounter with Lord Voldemort, one of the most powerful wizards of all time and the primary antagonist in the series, when he was just one year old. His parents, James and Lily Potter, were killed in this incident on 31 October 1981 in their home in Godric's Hollow, while trying to protect baby Harry from Voldemort. James died first while duelling with Voldemort in the entrance hall of their house. Lily's dying act, choosing to sacrifice herself to save her infant son, placed Harry under an ancient magic that protected him from Voldemort, while making Harry an orphan.
Subsequently, when Voldemort tried to kill Harry, the curse backfired, rebounding on Voldemort and leaving him bodiless while Harry survived unscathed, apart from gaining his now-famous lightning bolt-shaped scar on his forehead. This resulted in the loss of Voldemort's powers (but, significantly, not his death), as well as his exile and eventual decline from a position of power and fear in the wizarding world. The incident has led to Harry being heralded as a celebrity, often touted as "The Boy Who Lived", as he is considered the only person (besides Voldemort himself, as the spell rebounded on him) to have ever survived Avada Kedavra, the Killing Curse. Many in the wizarding world consider Harry to be the reason for Voldemort's downfall.
Despite the fact that Harry survived Voldemort's attempt to murder him, it isn't until the fifth book that he has any idea of how or why Voldemort lost his powers. In the second book, Harry confirms this fact when he replies to a question asked of him by Tom Riddle:
''I don't know why you lost your powers that night, but I know why you couldn't kill me... ''
After the death of his parents, Harry was forced to live with the only family he had left – his mother's Muggle sister, Petunia Dursley, and her husband, Vernon, in the small town of Little Whinging, Surrey, England. The Dursleys live at number four, Privet Drive in a large, impeccably maintained four-bedroom house and seem to be moderately well off. However, throughout the first eleven years of Harry's life, they neglected him in favour of their own son, Dudley, and in an attempt to remove all traces of Harry's magical self to make him 'normal', they told him nothing about his past and kept him fully isolated from the wizarding world and its potential influence.
Harry is categorised as a half-blood wizard, in spite of the fact that both his parents were magical. His mother Lily (Evans) Potter was Muggle-born, and according to Rowling, to those to whom blood purity matters a Muggle-born is equivalent to a Muggle - and referred to derogatively as a "Mudblood"; thus Harry is considered a half-blood due to his non-magical maternal grandparents.
Not much is known about Harry's relations. His mother, Lily Evans, was born into a Muggle family, and after the death of his parents, Harry was sent to live with his mother's sister, Petunia Dursley, and her family. Harry's father, James Potter, was born into a pure-blood wizarding family, to somewhat elderly (by wizarding standards) parents. This probably means that Harry is distantly related to other pure-blood families through his father, as Sirius Black once told him that all the old pure-blood families are related through intermarriage.
James and Lily left Harry a large inheritance of wizard money, which he uses for his Hogwarts supplies; Harry's friend Ron, who comes from a large and relatively poor family, is sometimes envious of this.
