No it was Peter Pettigrew. Harry unwilling helped (He was blood from the enemy).
I'm assuming you're talking about the battle at the Ministry at the end of the Order of the Phoenix. Voldemort takes over Harry's body and talks through Harry. Voldemort can't stay in Harry's body/mind, though, because of Harry's utter goodness. The love and friendship that Harry feels for his friends is actually painful for Voldemort to experience firsthand, so Harry is able to force Voldemort out of his head.
In the final chamber of "Harry Potter and the Philosopher's Stone," Harry discovers Professor Quirrell, who is revealed to be working for Lord Voldemort. Quirrell is attempting to steal the Philosopher's Stone to restore Voldemort to power. The confrontation highlights the strength of Harry's courage and the love that protects him from Voldemort's dark magic.
Lord Voldemort's boggart is his own dead body. His riddikulus is Harry drooping dead.
Lord Voldemort shared a body with Professor Quirrell.
Voldemort entered harry's body for a few moments before retreating.
Voldemort dies, Harry does not.
In the Deathly Hallows , the third time with Voldemort killing Harry ( it was in the Hogwarts' Forbbiden Forest) the spell had backfired on Voldemort again. It made Harry go in to see Albus Dumbledore in King's Cross.After Voldemort casts the killing curse, Harry goes unconscious. Dumbledore's spirit leads Harry's spirit to a couple of seats and commends him for his bravery. He acknowledges that he is dead, but says that Harry is probably not. He explains, or helps Harry to figure out, that while Voldemort has just killed the part of his own soul that was embedded within Harry, Harry is still alive because Voldemort reconstituted his own body out of Harry's blood (in Harry Potter and the Goblet of Fire). Because Voldemort contains Harry's blood, as long as Voldemort is alive he preserves Lily Potter's charm, so Harry can't die at his hand. Thus, paradoxically, while Harry had to die before Voldemort could, Harry can't die while Voldemort lives. They have a double bond, with Voldemort's soul in Harry and Harry's blood in Voldemort.
At the end of Harry Potter and the Deathly Hallows, Harry managed to destroy his horcuxes. Harry and Voldemort had a final battle at the Great Hall at Hogwarts, and Harry managed to kill his body. Without Voldemort's horcruxes, he is mortal, and he died after Harry defeated him in a duel.
Lord Voldemort did want to kill Harry. He promised that he wouldn't because Harry had the philosopher's stone and Voldemort wasn't powerful enough to take it off him, but Voldemort was unlikely to actually keep that promise even if Harry had joined his side and handed the stone over.The only reason Voldemort didn't try to kill Harry is because he had no body, he was sharing Quirrell's but had no actual control over him.
Lord Voldemort was sharing his body with Professor Quirrell, resulting in Harry's scar hurting.J.K. Rowling revealed that Harry's scar hurt whenever he was near Lord Voldemort because the Horcrux inside him was trying to leave Harry and return to Voldemort.
Yes, and because of Harry's blood that was in Voldemort's artificial body -- that created a special connection between the two of them, giving a Harry a chance not to die when the horcrux in him got destroyed.
it is the piece of voldemort's soul that lived inside harry. it was separated from harry's body when voldemort cast the avada kedavra spell on him, he basically destroyed his own horcrux (harry)
