How did Harry Potter defeat Lord Voldemort?

Answer 1

Lord Voldemort uses an old form of magic to return. Peter Pettigrew sacrifices his hand, they forcibly take blood from Harry Potter and use a bone from his fathers grave. This, and Voldemort's body are added together in a potion and Voldemort emerges.

Answer 2

Through some kind of dark potion and ritual. Peter Pettigrew helps him, donating his hand in the process. Harry's blood is also used, as Harry is 'the enemy' and the bones of Voldemort's father are required too. (Hence the graveyard setting.)

Answer 3

By spell and potion.

"Bone of the father, flesh of the servant, blood of the enemy"

Answer 4

He made a potion which involved using a bone from his father, flesh from his servant and blood from his enemy.

Answer 5

Voldemort shot the killing curse at Harry and Harry used a spell to backfire it at him. The killing curse backfired and killed Voldemort, so technically it was suicide.

Answer 6

He did have horcruxes that time; six, to be precise (diary, ring, cup, locket, diadem, Harry, Nagini). (Of course the HCX's didn't help him to get a new body, but Peter Pettigrew did help.)

Answer 7

He got hurt by Voldermort and he then has the ability to see what Lord Voldermort is doing.

Answer 8

The books, especially book 6, give a lot of background information about Lord Voldemort's childhood and youth, but ultimately, it was a decision he made himself.
