Lord Voldemort

Lord Voldemort is a fictional character and the primary antagonist in the Harry Potter novel series written by British author J. K. Rowling. Voldemort made his debut appearence in the first novel of the series, "Harry Potter and the Philosopher's Stone" which was released in 1997. Voldemort appeared in all the following installments of the series, with the exception of the third installment "Harry Potter and the Prisoner of Azkaban". Lord Voldemort has also appeared in all the corresponding film adaptations as of present date.

Voldemort's primary rival in the series is the main protagonist named Harry Potter, who through a prophecy was predicted as Voldemort's equal. Even though Voldemort had fallen twice in the series, the wizarding community still feared him so much that they refused to refer to him by the name Lord Voldemort. Most of the wizarding community instead refer to him only as "You-Know-Who" or "He Who Must Not Be Named." Even his followers (called Death Eaters) fear him so much that they refer to him simply as "The Dark Lord". In the seventh and final installment, he is called the "Chief Death Eater" by presenters of a radio show called "Potterwatch".

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.
