Lord Voldemort

Lord Voldemort is the Primary antagonist of the Harry Potter series of books. He has appeared in every book, except Prisoner of Azkaban.

Name
I am Lord Voldemort is an anagram of the words Tom Marvolo Riddle. It is stated that he dropped the name Tom Riddle which was a legacy of his father, a Muggle, and therefore in Voldemort's eyes inferior to himself. Most wizards, with two exceptions (Harry Potter himself, and Professor Dumbledore) refuse to say "Voldemort", preferring to use "He Who Must Not Be Named", or "You Know Who", even in print. His followers (The Death Eaters) call him "The Dark Lord".

Genealogy
Lord Voldemort is a direct descendant of Salazar Slytherin, and the last of his line, although many Suefics feature his daughter who inevitably attends Hogwarts and becomes friends with Harry and co. Voldemort's mother was Merope Gaunt, a witch, and his father Tom Riddle Jr, the son of the squire in the village of Little Hangleton. Lord Voldemort had two known relatives on his mother's side, an Uncle, Morfin Gaunt, and a Grandfather, Marvolo Gaunt. Both died during or after incarceration in the wizard prison Azkaban. On his father's side both his grandparents were alive, but the teenaged Voldemort killed both, along with the father who abandoned him.

Appearance
Voldemort is described as being "tall, and skeletally thin" and as having a face "whiter than a skull, with wide, livid scarlet eyes and a nose that was as flat as a snake’s with slits for nostrils". It is speculated that this inhuman appearance is a result of his surrendering his humanity by creating sevenHorcruxes, each containing a piece of his soul.

Actions
J.K Rowling has described Voldemort as "a raging psychopath, devoid of the normal human responses to other people's suffering". During the years he was powerful he collected a large number of followers who assisted him in carrying out a large number of murders and other acts of terror. Voldemort, in common with many wizards, has a great belief in the "Purity of Blood". Those deemed impure, including Muggle born Wizards, and those with one Muggle parent or grandparent are treated by him as second class citizens. This attitude is not dissimilar to that displayed by Hitler and his Nazis in Germany towards the Jews.

Skills
Voldemort is portrayed as being highly intelligent, and very powerful. He is an accomplished Legilimens and Parselmouth as well as appearing to fly, unaided by a broom or charm. The core of Voldemort's wand is a tail feather given by the Phoenix belonging to Dumbledore.
