Draco Malfoy (played by Tom Felton)
As the only child of a wealthy and powerful family in Voldemort's inner circle, Draco enjoyed a spoiled childhood. He wants to emulate his father and strives to prove his loyalty to Voldemort whenever possible.
Draco is Harry's biggest rival at Hogwarts and enjoys nothing more than tormenting members of the Gryffindor House. He plays directly against Harry as Seeker for the Slytherin Quidditch team.
