Throughout the Harry Potter movies, Draco Malfoy (portrayed by Tom Felton) is a pure-blood loving bully. Harry and Draco are rivals on the Quidditch team and in real life. Draco is always making fun of Ron's poorness, Hermione's blood status, and Neville's incapability. He is not much more than a rival to Harry until the sixth book.
