(1)Albus Percival Wulfric Brian Dumbledore
(9)Katie Bell
I've heard good arguments that Albus has surpassed Snape for the character with the most depth. And he's always been the character with the most style.
(5)Aberforth Dumbledore
(4)George Weasley
The funny thing about Fred and George is that Fred has 80% of the lines, and George has about 20%.
On the other hand, I like Aberforth, I like him a great deal. He speaks ill of his brother, as you'd expect from his history. The funny thing is how very much his criticisms ring true (when we were inclined to dismiss, say Rita Skeeter). When Alberforth says that Albus is asking unrealistic and dangerous things of Harry, these criticisms are believable and make a lot of sense. And yet, underneath his pesimism, and inclination to believe that Albus will only get more people hurt, and bitterness over events that happened a century ago, he has a glimmer of hope. Also, goats are funny.
