Draco Malfoy
Draco Malfoy is the pure blooded son of Lucius and Narcissa Malfoy. He was a notorious bully to Harry Potter and his friends because Hermione has Muggle parents, Draco was also assigned to kill Dumbledore, but his heart told him otherwise and Snape had to do it for him. Draco, like his family, is part of Slytherin house.
