Draco Malfoy is a pureblood, the sole heir of the wizards Lucius and Narcissa Malfoy.
Draco entered Hogwarts at the same time as Harry Potter and joined the Slytherin. Always accompanied by Vincent Crabbe, Gregory Goyle, he quickly became the ennemy of Harry Potter and his friends for the first six years of their schooling.
In his sixth year, Draco sided with Lord Voldemort. Voldemort puts his mark on his arm and orders him to kill Albus Dumbledore. Draco learns to use the Vanishing Cabinet and proves to be a very good Occlumens as he manages to hide his intentions from Severus Snape.
Draco is also a member of Slytherin's Quidditch team, as well as Dolores Umbridge's Inquisitorial Brigade. He later became a Death Eater, as did his parents.
His wand, with its simple, uncluttered style and character, contains a unicorn's mane.
