Tom Marvolo Riddle 

I am Lord Voldemort.

Harry: You. You're the Heir of Slytherin. You're Voldemort.

Tom Marvolo Riddle: Surely you didn't think I was going to keep my filthy Muggle father's name? No. I fashioned myself a new name, a name I knew wizards everywhere would one day fear to speak, when I became the greatest sorcerer in the world!

Harry: Albus Dumbledore is the greatest sorcerer in the world!

Tom Marvolo Riddle: Dumbledore's been driven out of this castle by the mere memory of me!
