Taken from J.K Rowling's award-winning books "Harry Potter", Draco Malfoy is the archnemesis of the main character, Harry Potter and his two best friends, Ronald Weasely and Hermione Granger.
Best known for being the "insufferable git" of both the books and films, he is one of the more "evil" characters and is able to maintain his position in many different situations. In latin, "Draco" is "dragon" or "serpent" and the root of his last name "Mal foi" is "badly faith" in french. Therefore, you can draw the conclusion that his name means "Dragon/Serpent bad faith" or "Badly Faith(ed) serpent/dragon".
Draco Malfoy is portrayed in fanfiction as either Harry Potter's/Hermione Granger's/Ronald Weasely's/Ginny Weasely's/various other characters' lovers. This is not "canon", nor is it probable, though it may be possible. His homosexuality/bisexuality/bicuriousity is hinted at in many fanfictions and role-playing threads.
In all actuality, D.M is one of the most developed characters in the Potter-verse because many do not feel the need to say "is this what he will do?" But one of the more difficult characters to write because of his development.
In the Films, He is portrayed by Tom Felton
