Lucas was a synthetic sleeper agent sent by Lasalle Bionational to infiltrate the crew of the Weyland-Yutani Corporation transport ship USCSS Montero.
Behind the scenes[]
Lucas appears in Alien: The Roleplaying Game — Chariot of the Gods, in which the synthetic can masquerade as one of the crewmembers aboard the Montero; the precise identity of that individual is subject to the Game Mother's discretion, however.
