Draco Malfoy
Draco Malfoy is the school-side nemisis of Harry Potter and the rest of the trio (Hermione Granger and Ron Weasley). In the books is an arrogant asshole, but most people like him because of this and because they find his film counter-part attractive, Tom Felton.
Person 1: How can you like Draco? He's such a jerk
Person 2: But have you even seen Tom Felton? He's so hott.
