Green Lantern versus Aliens is a four-issue comic book intercompany crossover mini-series published jointly by DC Comics and Dark Horse Comics monthly from September to December 2000. It is written by Ron Marz and illustrated by penciller Rick Leonardi and inker Mike Perkins, with covers by Dwayne Turner. In 2001, the series was collected into a single volume with a new cover by artist Eric Kohler. The series stars several Green Lanterns, primarily Kyle Rayner, and the titular Xenomorphs from the Alien films. The story is apparently outside of DC Comics Universe canon, as Brik and Salaak are alive in current Green Lantern continuity; the series is set sometime after the destruction of the original Green Lantern Corps.
