Harry is the Heir of Slytherin (through his mother's side) and also related to Gryffindor (through his father's side) though the current Heir of Gryffindor is Neville.
Potter is chosen by Voldemort marking him to be his equal. He chose Harry based on the prophecy by Sybill Trelawney. The prophecy fit two children, Harry Potter & Neville Longbottom but Voldemort chose Harry. And thus Harry became the chosen one.
Indeed, Harry was the "The Chosen One" because Voldemort chose to believe that the prophecy was talking about Harry, the half-blood like himself and thus his equal. Harry survived the Killing Curse because his mother sacrificed her life for him and gave him a protection from Voldemort until he comes of age (at 17).
Finally it is Neville who kills Voldemort in the films, as Harry and Voldemort duel Neville kills the snake and before the colliding magic ends Voldemort already starts to flake, Harry then hits him with a disarm spell, but not a killing curse, so Voldemort's death is triggered by Neville killing the snake, making him
Neville Longbottom was also a candidate for the “chosen one” label, as he also fits the prophecy. By targeting him and trying to kill him, Voldemort marked him as his equal, while Neville got to live his life without that burden (though that doesn't mean he had an easy life).
Yes the prophecy says the boy to conquer Voldemort was born at the end of July which could of been Harry or Neville but Voldemort went after Harry making the prophecy about Harry not Neville. But it could have been about Neville if Voldemort decided to go after him instead of Harry,but of course he didn't.
You read that right. There is a theory floating around that Queenie is Voldemort's mother. His mother, Merope (Gaunt) Riddle, died in childbirth. The first time we meet Queenie is in late 1926 in New York City, New York, very much not pregnant.
It is stated that both halves of the Kyuubi merge with Naruto after the war, so yes, Naruto commands the full Kyuubi's power. No,Naruto still other half of karma when minato died the half of the nine tails died along with him. Naruto doesn't get the full power.
Naruto DID only have half of Kurama sealed inside him until the war. During the war, the other eight tailed beasts gave him some of their chakra. So, he has a part of every tailed beast sealed inside him.
