Aliens is a line of several comic books set in the fictional universe of the Alien films published by Dark Horse Comics from 1988 forward. The stories often feature the company Weyland-Yutani and the United States Colonial Marines. Originally intended as a sequel to James Cameron's 1986 film Aliens, the first mini-series features the characters of Rebecca "Newt" Jorden and Corporal Dwayne Hicks. Later series also included the further adventures of Ellen Ripley, with other stories being unique to the Alien universe and are often used to explore other aspects of the species, such as their sociology and biology, and also tying into Dark Horse Comics' Predator and Aliens vs. Predator lines. The novels by Titan Books also crossed over with the comics leading to some shared continuity.
