Dennis Monroe Parker was a male Human who was the chief engineer aboard the Antares-class freighter Nostromo. He was serving on the ship during its fateful voyage in 2360 when it encountered a Xenomorph on LV-426, an incident that eventually led to the destruction of the ship and the loss of all but three Starfleet officers.
Parker was killed by the Alien while gathering oxygen tanks that would allow the survivors to flee the Nostromo in its shuttle, the Narcissus.
