This is Dumbleldore he is the head master of Hogwarts.
In the 4th year he saved Harry from Umbridge because Pr. D said that he did the organising of the Dumbledores Army (Harry did the organising really. )
This is Harry Potter. He is the only person who lived the killing curse from Voldemort or anyone.
He would of died if it wouldn't of been for his mum and dad. They sacrificed there lives for his.
