Harry Potter villainsFew villains in movie history have inspired as much ire, as much fear and as much nausea as the man known alternately as You Know Who, He Who Must Not Be Named, the Dark Lord, Tom Marvolo Riddle and -- last but not least -- Voldemort (Ralph Fiennes). The Harry Potter archvillain has the bald head and winning personality of Darth Vader, the crusty face of a leper, the thin forked nostrils and flat nose of a serpent, and the dental hygeine of an Englishman circa 1800. In summary, he is one ugly mother, inside and out.

In honor of Voldemort's vile return to the big screen in Harry Potter and the Order of the Phoenix, Moviefone has ranked the best of the worst Harry Potter villains, beginning with the dubiously diabolical and powering straight on through to the most wretched, foul-smelling, remorseless, compassionless fiends in Hogwarts history.

Check out Moviefone's Harry Potter Villains: The Best of the Worst gallery, then tell us who you think are the most odious evildoers in the Potter-verse. Did we miss any on our list? Did we include any that shouldn't be on there? And, lastly, do you think Voldemort would ever consider rhinoplasty?
