Lord Voldemort

Lord Voldemort (birth name: Tom Marvolo Riddlle) is the central antagonist of the Pooh's Adventures of Harry Potter series of books, films and video games. He is a dark wizard who wishes to gain immortality

Following an unhappy childhood, a basilisk attack and splitting his soul into seven horcruxes, Voldemort gathered followers and brought them over to his side and killed anyone that stood up to him.

Two of them, Lily and James Potter, fought against him, but neither of them lived, except their son.
