Dennis Parker (Earth-5875)

"Can we just talk about the bonus situation?"

- - Dennis Parker to Arthur Dallas

Dennis Monroe Parker was an employee of the Weyland-Yutani Corporation and the chief engineer of the commercial freighter Nostromo. He served as a member of the crew during its final voyage in 2528 following its encounter with a xenomorph on Acheron, which led to the destruction of the ship and the deaths of all crew members, with the exception of Ellen Ripley. He was killed by the Alien while gathering oxygen tanks so he and the remaining survivors could escape the Nostromo aboard the Narcissus.
