Ain't easy to describe Lord Voldemort. I know there is already an entry for Voldemort, but I wanted to write one as "Lord Voldemort", and here it is.
Personally think that Ralph Fiennes deserves to be given the title of:
Lord Voldemort is a fictional character and the primary antagonist in the Harry Potter novel series written by British author J. K. Rowling. Voldemort first appeared in Harry Potter and the Philosopher's Stone, which was released in 1997. Voldemort appeared either in person or in flashbacks in each book in the series, except the third, Harry Potter and the Prisoner of Azkaban. Voldemort has also appeared in all the corresponding film adaptations as of present date, except the third.
In the series, Voldemort is the main enemy of Harry Potter, who according to a prophecy has the power to defeat him. He aims to conquer the wizarding world, which fears him so much that they refuse to refer to him by his name, instead saying "You-Know-Who" or "He-Who-Must-Not-Be-Named." Even his followers only refer to him as "The Dark Lord". He was born as Tom Marvolo Riddle, and is the last descendant of wizard Salazar Slytherin, one of the founders of Hogwarts School of Witchcraft and Wizardry.
Several people have portrayed Voldemort in the films, but the most referenced actor is British actor Ralph Fiennes, who has portrayed him in the film adaptations of the fourth and fifth novels. In a 2006 BigBadRead poll, British school children voted Lord Voldemort their favourite literary villain of all time.
