4. Jason Teague (Jensen Ackles)
Though the character’s relationship with his mother was kind of weird, for a long time Jason was one of the more interesting elements of Smallville. The fact that the character went from being Clark’s football coach and a mentor, of sorts, to being fired for dating Lana, before becoming a truly bad egg, was an interesting arc within the show. Also, Jensen Ackles is totally handsome.
