Smallville‍ '​s first venture into comics was "Elemental", a one-off story by Gough and Millar which appeared in TV Guide during the series' first season and set in that period. Before the start of season two, DC Comics published a one-off comic based on the series. Entitled Smallville: The Comic, it has two stories. The first, "Raptor" by Mark Verheiden and Roy Martinez, is about an abused boy who mutates into a raptor (thanks to kryptonite) and tries to get revenge on the Luthor family. Michael Green and John Paul Leon wrote "Exile and The Kingdom", with insight into why Lex remains in Smallville after his father offers him a position in Metropolis at the end of season one.DC Comics than began publishing a bimonthly comic with stories about Smallville characters. Writer and x-script coordinator Clint Carpenter called the comic-book line a companion to the series rather than a non-canonical version. According to Carpenter, the comic-book line expands on events in the series (such as season-ending cliffhangers) and gives "additional depth" to characters with limited screen time on the series or whose storylines needed additional explanation.
