Lord Voldemort is the main villain from the "Harry Potter" movies and books. He is a cruel, ruthless and sinister wizard who wants to kill all humans so that wizards can rule the Earth. His lust for power mutated him into a snake-human hybrid. He killed Harry Potter's parents when Harry was a baby, but he was unable to kill Harry, thus he is obsessed with killing Harry and Harry's friends. To ensure his immortality, he put parts of his soul in several magical artifacts called Horcruxes. Harry, Hermione Granger, Ron Weasley and Luna Lovegood destroyed all of the Horcruxes, allowing Harry to kill Voldemort with the Master Wand, the most powerful magic wand in the world.
