After most of the Colonial Marines are wiped out by the Aliens on LV-426, Bishop is a medic and technician who ensures that the company's dropship receives Ripley, Newt and Hicks.
Immediately after his activation, Bishop is quizzed by a technician named Dr. Sasaki to ensure he does not suffer from any potentially dangerous faults in his character programming.
Sasaki releases Bishop into a room containing other similar androids, although she privately voices her concern that he may be flawed, possessing emotional capabilities exceeding his intended capacity, like that of the decommissioned "David" line.
Henriksen was one of several actors, including Michael Biehn and Bill Paxton, cast in Aliens who had collaborated with James Cameron on The Terminator.
[1] Roz Kaveney, in her analysis of Ash in From Alien to The Matrix: Reading Science Fiction Film, draws parallels to Bishop as a representation of the Three Laws of Robotics.
[2] Bishop was studied by LeiLani Nishime of the University of Texas Press in 2005 as a theoretical dramatization of how humans would deal with the presence of an Other concerning Ripley's initial apprehension about being near a synthetic after her life-threatening encounter with Ash.
[3] According to an article by Anton Karl Kozlovic of the University of Nebraska Omaha, Bishop's altruistic actions (which include rescuing Newt and Ripley) contradict a trend towards technophobia in pre-1990 films.
He also refuses to rescue the survivors at the end of the story, saying that his programming will not allow him to risk the Xenomorphs potentially contaminating the ship and subsequently spreading throughout the human race.
In William Gibson's unproduced script for Alien3, Bishop and Hicks became the series' main characters in lieu of Ripley, and they, along with another group of Colonial Marines, are involved in a Xenomorph outbreak on a massive space station, where the Aliens are being bred and studied for use as a bio-weapon.
