Another boogeyman no one in the wizarding world wants to meet is Lord Voldemort. While his presence is gradually seen through the Harry Potter series of movies, we come to realize he’s not only super powerful but also kind of a wizard genius. By splitting his self into horcruxes and hiding them, he’s able to live forever and terrorize Hogwarts and the wizarding world to his heart’s content. But, of course, then there was The Boy Who Lived.
