Fatherly figure and invaluable helper for Harry Potter in the Harry Potter series. Usually the one to give Harry the courage/resources he needs to accomplish whatever obstacles are put before him. Killed by Severus Snape in the sixth novel, but his death is questionable for several reasons:
1. He went FLYING off of the roof when hit by the curse. Everyone else simply dropped to the ground, dead before they even hit it.
2. What happened to his wand? In the song sung by a drunken Hagrid and Slughorn, it says, "They laid him to rest with his hat inside out and his wand snapped in two, which was sad." But there was no mention whatsoever of his wand after it rolled to the corner of the roof. Maybe he still needs it?
3. A phoenix. Why a phoenix? Why not an owl, the customary symbol of wisdom which is the very quintessence of our definition of Dumbledore? I believe that, like the phoenix with which he is so closely associated, Dumbledore will rise from the ashes...in one form or another.
