Why couldn't Voldemort touch Harry?

Answer 1

It was because of his mother and father. They died to save him, and that kind of act leaves a mark. Their love for him was so strong that it protected him from the killing curse. It is said that it was agony to touch someone marked with something so good. So, as a result, the curse rebounded off Harry and struck Voldemort. Voldemort then became non-human, he became more of a spirit. He needed to share a body with someone. Not being truly alive, he could not be killed.

Answer 2

That is what the prophecy that Sybil Trelawney made said. Sevurus Snape overheard Trelawney tell this to Albus Dumbledore, so then gave this information on to Voldemort. Voldemort then tried to kill Harry when he was one year old, but didn't succeed.

Answer 3

Because of all that is happened between the two and also for Voldemorts pride as Harry was the one to weaken and almost defeat him in the first place. Harry is the only one standing in the way of Voldemort coming back to his full power.

Answer 4

Harry Potter was the master of the Elder wand, which Lord Voldemort was using. But the Elder wand wouldn't go against it's own master which is how Voldemort died.

Answer 5

Because of the prophecy, which he interpreted to refer to Harry.

Answer 6

Because he's the Chosen One.
