Bellatrix
He was once a strikingly handsome man. Brilliant, he was too with brain and wit. Oh, but cunning and evilness. You will not believe what a combination of those two traits along with a love for power will do. He was vanquished for sometime while the wizarding word celebrated grandly but he rose once again, all traces of the handsome man now gone. His eyes, like snakes. His head, bald. What a utterly scary person to look at.
