The replica made and sold by the Noble Collection does, yes.
Yes, the horcrux inside of Harry Potter
No, only the Horcrux inside him was.
Harry Potter can talk to snakes. He loses this ability after the Horcrux inside him is destroyed.
He did not die. He married and had three children. A small piece of Lord Voldemort's soul was in Harry Potter, making him a Horcrux, and when Voldemort hit Harry with the killing curse, supposedly killing him, he killed the Horcrux inside Harry.
I guess you mean "Voldemort"? That's because Voldemort tried to kill Harry, but when he did, he actually made a Horcrux. Harry is the horcrux, but he is Harry as well. The Horcrux inside Harry gets killed in the last book.
Harry Potter can speak English. Until the Horcrux inside him was destroyed he could also speak parseltongue.
Voldemort casts the killing curse onto harry which then "kills him", yet because part of voldemorts soul was inside harry voldemort only destroyed part of his horcrux and not harry.
So you mean how was the horcrux in Harry destroyed? Well voldimort tried to kill him but instead destroyed the horcrux inside Harry, so Harry was no longer one of voldimorts horcruxes. This happened in Harry potter 7
The reason he's an unintended horcrux is because the night he tried to kill Harry, he put a piece of his soul inside him(how you make a horcrux). He didn't mean to, though.
No, but the diary Horcrux, was destroyed.
