Maybe grab some pumpkin juice, have a party, use your wand... you know, the normal things wizards do.
Harry wins the battle of the Deathly Hallows in the fight between him and Voldemort, and Voldemort is defeated.
Celebrate.
harry after defeating voldemort became auror and was also the defense against dark arts teacher in Hogwarts's.
b/c harry's scar was a horcrux, meaning it conained a piece of voldemort's soul
He defeated Lord Voldemort and saved many lives.
Minerva McGonagall becomes Headmistress.
He defeated Voldemort as a baby. He was the boy who lived.
No, Neville didn't kill Voldemort, Harry did - but he did kill Nagini, Voldemort's snake which was the last remaining Horcrux.
You can't, he's already been defeated :(
Harry used Draco Malfoy's wand and defeated Voldemort with the curse "Expelliarmus". Voldemort sent Avada Kedavra to Harry, and at the meantime, Harry's curse Expelliarmus, conflicts the curse so he won.
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.
Harry prevented Lord Voldemort from gaining the Philosopher's Stone and returning to power. Voldemort was very weak and was forced to go into hiding, where he remained until 1994 when he was found by Peter Pettigrew.
