Aliens is a non-canonical comic book series set in the fictional universe of the Alien films. It was first published by Dark Horse Comics in 1988. 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. Other stories are completely unique to the Alien universe, and are often used to explore other aspects of the species, such as their sociology and biology.
