Interviewer: What is it about robots that make them so robotic? At Weyland Industries, it has long been our goal to create artifical intelligence that is almost indistinguishable from mankind itself. Prometheus. 20th Century Fox. 2012. Movie.
Synthetics
|
|
|---|
Synthetics, also called Artificial Persons, are sometimes used to assist Strike Teams on board all Colonial Marine ships. Although they perform a wide variety of services for their Strike Teams, their most important role is that of backup Pilot and Navigator in the event that Auxiliary personnel are injured or killed.
Synthetics possess limited artificial intelligence, and units which have been in service for long periods develop individual personality traits and emotions. This personality is sharply limited by the Behavioral Inhibitors built into every Synthetic, which prevent them from taking any aggressive actions, endangering human life or allowing it to be endangered, or disobeying orders (exception being Ash or David8). These inhibitors are vital to safety, as Synthetics possess remarkable abilities. In addition, Synthetics can be programmed with a wide variety of Skills and are extremely durable.
Because of the limited nature of Synthetics' creative abilities, they are not well suited to tasks which require original thought. Their logical abilities and speed of thought are ideal for scientific work, but only in structured environments where their duties are clearly defined. No human scientist can work as quickly and efficiently in a laboratory, but Synthetics are very poor at deciding how to approach a problem, and are almost incapable of assigning values to the results of their work.
The Synthetic industry is one of the most closely monitored in the ICC, owing to the potentials of Synthetics and the threatthey might pose to Humanity. The inhibitors on their behavior are carefully modified to suit each new type of Synthetic and each new set of programming, to guarantee that there are no unpredictable situations and no loopholes. As a final check, every Synthetic is programmed to stop all activity if it cannot determine what its proper action should be. Despite these controls, there are rumors that one or more Corporations have created Synthetics without the standard inhibitors, and that they are even using them as assassins. No evidence exists to support these rumors.

Charlie Holloway: David, why are you wearing a suit, man?
David: I beg your pardon?
Charlie Holloway: You don't breathe, remember? So why wear a suit?
David: I was designed like this because you are more comfortable interacting with your own kind. If I didn't wear a suit, it would defeat the purpose.
Charlie Holloway: They're making you guys pretty close, huh?
David: Not too close, I hope. Prometheus. 20th Century Fox. 2012. DVD.
David: War, poverty, cruelty, unneccessary violence. I understand human emotions, although I do not feel them myself. This allows me to be more efficient and capable, and makes it easier for my human counterparts to interact with me. Prometheus. 20th Century Fox. 2012. DVD.

Ash
|
- "Born" 2118
- Affiliation: Weyland-Yutani; USCSS Nostromo
- Male Hyperdyne Systems 120-A/2 synthetic
- Bio Data: Dark, graying hair. Green eyes. 5'6".
- ID number: 111/C2/01X
Prior to 2121, little is known about Ash and his activities. Ash was science officer grade M-1 and operational for 4 years.
Weyland-Yutani detected and partially decoded a transmission coming from the derelict on LV-426. On June 12, 2121, two days before the ship left Thedus, Ash was assigned to the Nostromo to secretly ensure the retrieval of the alien creature likely to be found there. He replaced the vessel's existing science officer, who had previously served with Captain Dallas on several occasions. His duties include administering medical treatment, conducting biological research and investigating any alien life forms the crew may encounter. Ash's programming secretly allows and encourages the harm of humans.
After take-off, Ash performed routine health checks on the crew before they entered hypersleep for the journey home.
The Nostromo received the Spacey Jockey signal emanating from LV-426 and was pulled out of hyperspace. The crew went on to investigate the signal.
When Kane is infested by an Kiande Amedha facehugger, Ash breaks quarantine protocol by allowing him to be brought on board. During Kane's impregnation, Ash observed the process and was responsible for Kane's medical treatment and preliminary research on the alien organism.
Ash assaults Ripley after the ship's computer, MOTHER, reveals that Ash's special orders are to ensure the return of the Kiande Amedha to Weyland-Yutani's laboratories, even at the expense of the crew. He is disabled by Parker, revealing his true identity as an android.
Ash's mangled body is briefly powered back up by the crew, so that he can confirm his directive and assure them that they cannot defeat the Kiande Amedha. His body is incinerated by Parker shortly after. However, unknown to the crew, Ash had already transferred part of his AI programming to the Narcissus.
While Ripley is in hypersleep, Ash keeps the shuttle drifting for thirty-seven years. Then he detected the distress call sent out by the DSMO Marion and rerouted the shuttle to intercept it, hoping to continue with his mission to acquire a Kiande Amedha specimen for Weyland-Yutani. Chris Hooper, an engineer who is part of a mining expedition on LV178 where the miners have discovered trimonite, also encountered Kiande Amedha.
Soon after arriving at the Marion, Ripley learned of Ash's survival. Ash reveals himself via the Seegson terminal he uploaded himself into. Ash renews his plot against the humans. When Sneddon is impregnated with a Chestburster, Ash planned to arrange the deaths of the rest of the crew. This way, she would enter hypersleep aboard the Narcissus, allowing him to deliver her — and the embryo she carried — to Earth. Sneddon killed herself before Ash could put his scheme into motion.
With his plans ruined, Ash planned to continue his journey with Ripley. However, Ash was finally destroyed when Hoop wiped the AI's program from the shuttle's mainframe using a computer virus before the Narcissus departed the Marion. With Ash destroyed, Ripley drifted through space for a further twenty years before being rescued.
B
Bishop
|
|
|---|
- Assembled on LX-469.
- Bio Data: Male synthetic.
Bishop belonged to a series of androids modeled after Weyland-Yutani founder Charles Bishop Weyland. He is the android executive officer assigned to the Sulaco and is primarily responsible for planetary maneuvering.
A superior version of older android models, Bishop was, unlike Ash, fitted with ethic programming preventing him from harming a human being, keeping in line with official regulations.
Upon learning about Ripley's past with Ash, Bishop clarifies to Ripley that his programming calls for complete loyalty. Ripley is still distrustful.
After most of the Colonial Marines are wiped out by the Kiande Amedha on LV-426, Bishop acts as a medic and technician. He ensures that the company's dropship receives Ripley, Newt and Hicks.
Upon boarding the Sulaco, Bishop is impaled and ripped in half by the stowaway Alien Queen. When Ripley defeats the Queen by opening the airlock, Bishop saves Newt. He is subsequently placed in cryosleep with Ripley, Newt and Hicks.
When the Sulaco crashes into Fury 161, Bishop is damaged beyond repair and thrown into the prison's landfill. He is partially repaired by Ripley for speech and memory functions, so he can disclose the events leading to the crash. He requests that Ripley shut him down permanently, which she complies with.
Bishop, Michael
|
|
|---|
- Bio Data: Male synthetic. Brown hair. Hazel eyes.
- "Born" 2127
- Died: 2194
- Alt Name: Bishop II
- Affiliation: Synthetic Component Designer for Weyland-Yutani
A "rescue crew" that had been dispatched by the business after Francis Aaron had notified them of the kiande amedha's presence there escorted Michael when he first arrived on Fiorina 161. He made an attempt to persuade the Lieutenant to accompany him after Ellen Ripley destroyed the "Dragon" so that his medical staff could extract the Queen that was growing inside of her. Francis Aaron attacked Michael with a wrench, almost ripping off his ear in the process. For the event, the commandos shot and murdered Aaron. Michael yelled that he wasn't a robot. Then, Michael let slip that he needed the creature and instructed Ripley to "think of all they could learn from it."
Ripley gracefully plunged to her death into the foundry's hot lead after refusing to accompany Michael on his trip. Michael yelled, but it was ineffective. Together with the team and Robert Morse, the last survivor of the incident, he left.
Michael opted to board the USS Sulaco to learn more about its prior location in the hopes of discovering the kiande amedha hive on LV-426 despite his failure to successfully retrieve the Queen embryo from Ripley. Finding the hive inside the ruins of the Hadley's Hope colony, Michael and his research team set up the Origin Facility and started capturing kiande amedha specimens for study.
Michael used the FTL ship, Resolute, to flee LV-426 once the kiande amedha took control of the Origin Facility.
The remaining USS Sephora Marines managed to stop the ship and eventually engaged Michael, who was still a mystery to them. As O'Neal prepared to kill Michael, the Marines begged to spare him, but Bishop intervened and persuaded the Marines to do so. Hicks abruptly killed Michael after observing that he had been motionless throughout their time together in the space and concluding that he was just an android double left behind as a ruse. Bishop later logged on to the destroyed synthetic's CPU in an effort to gather information, and now claims to have "everything."
Blake
|
|
|---|
- Bio Data: Female advanced synthetic.
- Affiliation: Second Colonial Marines
Developed by the human military. Blake was part of a project to create combat androids which acted and felt like humans. As part of this project, the synthetics themselves were led to believe they were actual human beings.
In 2191, Blake, Bueller and the others received combat training and were formed into a military unit as First Squad, Fox Platoon, Company Able, 1st Extee Division, Second Colonial Marines. During this training, Blake proved to be an excellent shot and was awarded the Marksmanship Badge.
In 2192, she and her comrades were chosen to participate in the Benedict mission
and received special training under David Wilks to prepare them for combat with the Kiande Amedha. Blake was one of the few who survived the Benedict's visit to the Kiande Amedha Homeworld. After returning
to Earth and landing at a military facility near Galveston, Texas, the survivors learned that
the military had no intention to fight back and would soon evacuate, leaving them behind on a dying
planet. Wilks tried to reason with an officer to consider other options, but the man rejected any
suggestions and drew his gun to keep Wilks in check. Blake, following her inherent programming to
protect human life, stepped in and distracted the officer long enough for Wilks to overwhelm him,
sacrificing her life in the process.
Bueller, Mitchell
|
|
|---|
- Bio Data: Male advanced synthetic.
- Affiliation: Second Colonial Marines
Bueller was part of a series of advanced androids developed by the military for high-profile missions. Apart from being cost-effective to produce, this particular line of synthetics were designed to act and feel like real human beings in order to prevent interaction problems with regular soldiers. As part of this objective, even the androids themselves were kept unaware of their real identity. Thus, Bueller and the others spent their entire existence inside a secured military facility believing that they were human.
Bueller had the appearance of a young adult and a carefree and gentle personality.
In 2191, the androids were banded together as a military unit, honing their skills in combat training. The squad was assigned to First Squad, Fox Platoon, Company Able, 1st Extee Division, Second Colonial Marines.
In 2192, Bueller and the other androids finally received their call to action when the military initiated the Benedict mission to retrieve a Kiande Amedha specimen from their homeworld. Bueller and the other synthetics entered special training under the second-in-command of the mission, David Wilks, to prepare them for a confrontation with the creatures.
On April 5, 2192, Bueller and the rest of the team departed from Earth aboard the Benedict. During the voyage, Bueller met a young woman named Billie, a survivor of an earlier Kiande Amedha attack who had been smuggled aboard by Wilks. Eventually, the two developed romantic feelings for each other and entered into a relationship, despite Wilks' misgivings.
On the Kiande Amedha Homeworld After arriving in orbit of the Kiande Amedha Homeworld, the Benedict was boarded by an intercept sent by the Bionational corporation in order to prevent the military from obtaining a Kiande Amedha before they could. Bueller and the rest of the androids were captured and sent to the surface together with the Bionational mercenaries. Bueller and his squad were herded into a hive in order to serve as bait for impregnation. However, due to their android nature, the eggs were not triggered to release Facehuggers as they did not sense a viable host nearby. Unharmed, Bueller and the others left the hive.
Meanwhile, the mercenaries outside were attacked by indigenous flying creatures and fled inside the hive where they were decimated by the Kiande Amedha. Following their programming that forced them to save human lives no matter the circumstances, Bueller and his comrades decided to rescue the mercenaries. Before entering the hive, Bueller said his goodbyes to Billie via his video feed, confessing his love for her.
Inside the hive, the androids were viciously mauled by the Kiande Amedha. It was then that the android identity was revealed not only to Billie, but also to the synthetics themselves: Bueller was ripped in half and reacted with great shock and disgust to the sight of his synthetic innards. Bueller and a handful of other survivors were extracted from the hive and reached the safety of the nearby dropship.
During the journey back to Earth, Bueller struggled with his self-disgust and Billie's distraught reaction. Eventually, however, the two overcame this crisis when they discovered that what mattered was the fact their love for each other was real.
After the Benedict had landed at one of the last military facilities on Earth left in the wake of a global Kiande Amedha infestation, Bueller was taken to the rehab laboratory by scientists under the pretense of repairing him. In truth, however, the personnel was only interested in cannibalizing Bueller and other synthetics for spare parts. Bueller managed to hide from the scientists long enough to be retrieved by Billie and Wilks. Together, they boarded a semi-automated cargo vessel named The American and left Earth for deep space.
C
Call, Annalee
|
|
|---|
- Female synthetic.
- Affiliation: The Betty
Annalee Call is the newest crew member of the Betty. She is also an undercover second generation synthetic (Autons) - androids manufactured by other androids to appear more human. When this new type of android became problematic, Call went underground in order to escape the subsequent purge and burned her wireless modem in order to avoid detection.
Before she left Earth, Call hacked into the computer systems of the Ministry of Defense and discovered information about its involvement with the Loki organization and the Auriga project, including the connection of the project with the crew of the Betty. Call knew about the Kiande Amedha and the immense threat to the galaxy it posed as she had studied Morse's account of the Fiorina incident and other banned historical documents about the creature.
Her programming dictated Call to protect humanity from such a danger, and she made it her mission to prevent the Kiande Amedha from being unleashed ever again. As the first step to reach this goal would be to kill Ripley8 and the Kiande Amedha queen inside her, Call enlisted on the smuggling crew of Frank Elgyn, who had agreed to provide the Auriga research team with human hosts.
After arriving on the Auriga, Call infiltrates Ripley8's cell to kill her, only to discover that the Queen has been extracted. Call is apprehended by Wren, who rounds up the crew of the Betty for execution. They overpower the USM soldiers and look to escape with Wren in custody. Wren shoots Call, causing her to fall to her apparent death.
She reappears, revealing her synthetic origin. Call orders the Auriga to make a crash course into Earth. Aboard the Betty Call is confronted by the Newborn, but is saved by Ripley8, who ejects it into space.
However, there was still Loki to deal with. Call informed Ripley 8 about the information she had found, and soon, Call, Ripley 8, Johner and Vriess started to raid about a dozen border stations in order to access their data banks in hopes of finding more information about Loki. It was Call's unique ability to hack into a computer that assigned her the role of retrieving the actual information, usually protected by Ripley8, while the rest of the crew would distract the security personnel and prepare their escape. Eventually, the terminal at Byzantium Station provided Call and Ripley8 with the information they had searched for so long: Loki's next target, the botanic space colony Domes Epsilon, which it had targeted for a Kiande Amedha infestation.
After arriving at Domes Epsilon, Call was part of the team that entered the station and met up with the colonists in the control center. There, Call and Ripley 8 managed to convince the group of the danger they were in. As Ripley 8 and Johner departed to investigate the backup bay as a means of escape, Call accompanied Adrian Shepherd, the security officer of Domes Epsilon, to pick up a stray colonist called Benedict. After finding Benedict's dead body and having sighted a Kiande Amedha, both returned to the control center, only to find out that the extent of the Kiande Amedha infestation was far greater than anticipated. Shortly before the survivors would reach the backup bay, Call and the rest got scattered in the jungle during a Kiande Amedha ambush. However, the android managed to secure one of the flivver vehicles together with Johner. Together, they picked up the remaining survivors and managed to reach the Betty safely.
Aboard the ship, Call learned from the interrogation of the Loki android agent Cody that other androids like her had survived the Auton Purge, something she had thought impossible before, and were now under Loki control. Aside from exterminating the Kiande Amedha threat, Call now had another, more personal mission: She promised Cody to find and rescue these androids, and Cody in turn provided her and Ripley 8 with their locations and information about Loki and his own role in the Domes Epsilon incident.

- Male synthetic.
David 8 is a synthetic and Peter Weyland's right-hand man. The eighth in a line of David models, representative of Weyland's unfulfilled wish for a son, David is constantly at odds with Weyland's disowned daughter, Meredith Vickers.
While the crew of the Prometheus rests, following Shaw and Holloway's discovery of the star charts in 2089, David spends his time leading up to the 2093 arrival at LV-223 studying the assumed dialects of the Engineers, as well as human culture and the dreams of the crew.
Following the awakening of the crew and the arrival at the moon, David accompanies the expedition to an artificial structure, where he acquires a vial of a black extraterrestrial liquid. On Weyland's orders, David contaminates a drink he hands to Holloway, so that he may impregnate Shaw with an extraterrestrial life form. David further explores the Engineer ship and cuts his feed to Vickers, to study a hologram in the bridge of the ship, to not only learn how to pilot the craft, but that there is a last Engineer surviving in cryo-sleep.
As Shaw enters Weyland's quarters, David prepares Weyland for the expedition to the Engineer ship, in order to awaken the last Engineer. David leads the expedition and awakens the Engineer. He translates Weyland's request for immortality, prompting the Engineer to silently decapitate him and murder the rest of the expedition, save for Shaw.
David's severed head witnesses the Engineer launch the ship and prepare to leave the atmosphere, which is thwarted by Janek crashing the Prometheus into the ship. David warns Shaw about the Engineer coming to kill her. He contacts her after she escapes the life support unit and tells her that despite their differences, he would like to help her escape the moon, as he can pilot another of the Engineers' ships.
After Shaw recovers his head and body, he promises to take her to the Engineers' home world, though he does not understand the relevance of the mission. Together with Shaw, he leaves LV-223 behind.
By 2104, David is discovered by the colony ship Covenant as the sole inhabitant of a hellish world originally thought to be paradise.

- Bio Data: Hyperdyne Systems 121-A/3 Synhetic female. Brown hair. Blue eyes.
- Affiliation: Otranto crew
Hope had been online for nearly 80 years when she was stranded aboard the Otranto, and she was one of the last members of her line remaining active. Once at the top of the line, her senior age meant she was gradually downgraded during her career, with longer and longer assignments on increasingly decrepit ships.
When the Otranto was evacuated in response to a chemical leak, Hope was left behind, adrift in space and with little chance of rescue. She eventually discovered a live Facehugger specimen in storage aboard her ship, and as her mind deteriorated due to the extended period she had been alone, she became determined to assist the Facehugger in fulfilling its biological purpose.

The Hyperdyne 129-4 was a high-end pleasure/love-slave synthetic popular in select upper-class circles on Earth in the 22nd century.
Due to the probable success of a weapons system their business was creating, two executives were discussing the model line, with one of the guys considering purchasing one for himself. His colleague and buddy then inquired about his friend's wife, to which the man said that he'd simply buy her one to keep her occupied.

- "Born" c2300
- Female synthetic.
Liliya has a photographic memory.
In June, 2356, Liliya is stationed to the USS Evelyn-Tew in the Alpha Centauri system. Her orders from Wordworth and the Founders are to blend into the background and inconspicuous.
By September, on orders from the Founders, she disabled the failsafes aboard the USS Evelyn-Tew to free the kiande amedhas onboard, steals their research they've accumulated regarding the species, and esapes on a lifeboat. As per the red-level emergency protocols, the ship's automated response had changed course to plunge into the nearest sun in Alpha Centauri, to burn everything and make sure nothing survives. Unfortunately, the ship had been set on an accelerated suicide trajectory, due to impact the star in under an hour.
By 2692, When Yautja attacks across the Human Sphere of space grow in frequency, Colonial Marine units are put on high alert. Soon, an invasion is feared. Meanwhile Liliya escapes from the Rage. Originally known as the Founders, the Rage are humans who have fled beyond the Human Sphere over the course of centuries. Now led by Beatrix Maloney, they are on their way back, bearing alien-inspired technology and weapons far exceeding those possessed by the Colonial Marines or Weyland-Yutani. Maloney’s aim is the subjugation and control of the Human Sphere. When Liliya flees, she carries with her a sample of their technology that might help humanity fight back. Maloney sends Alexander, one of her best generals, in pursuit.
Liliya, taken into custody on a Yautja ship and tortured at the hands of the warrior called Hashori, escapes with her captor when the Rage general Alexander closes in and attacks.

Maggie "worked" at Greenhouse 112 on LV-492 as a synthetic security dog when a single Facehugger went loose in the compound.
Maggie was killed in the tragedy, but she managed to save the life of the botanist, Julie, who worked at the facility.
Mari
|
|

- Bio Data: Synthetic female
Unknown to her crewmates, Mari was a synthetic sleeper agent of the Weyland-Yutani Corporation working aboard the comet plasma harvesting ship USCSS November.
Mari and three other survivors (Hannah, Alec, and Sturgis) made their way to the escape pods under the duress of a single kiande amedha during an outbreak aboard the USCSS November.
Mari was utilising a Motion tracker to advise the others to a safe route, but being a synthetic sleeper agent, she tried everything she could to stymie the survivors' advancement. Sturgis, frustrated by Mari's usage of the tracker, took it from her and left the group, citing a clear path and Mari's allowing him to leave. Mari prevents Alec and his severely pregnant partner Hannah from following
However, the kiande amedha murdered him shortly after. Hannah removed the axe and tracker from the dead Sturgis (Mari forbade Alec from accompanying her), and handed the tracker to Mari, who reassured the two that the company was on their way to rescue them.
Alec noticed that the group was going in circles as they progressed deeper inside the ship's limits under Mari's command, before being assaulted by the thing. Mari assisted Alec and Hannah in securing their EEVs after the group successfully fended off the Alien. Alec was suddenly grabbed by a Facehugger. As a second Ovomorph began hatching in front of the startled Hannah, Mari revealed her true nature and let out a nasty grin. Mari was stabbed by the kiande amedha before the EEV hatch was sealed, revealing that she had been synthetic all along.
Mari's mission was successful in the end, as the EEV launched and scheduled a rendezvous with a Weyland-Yutani probe carrying two kiande amedha specimens.

Quiet Eye is a video analysis software developed by Yutani Photo-Polygraph Technologies, a subdivision of the Yutani Corporation, in 2074. The Quiet Eye software is a very advanced and powerful tool, capable of identifying a person by dissecting picture elements and cross-referencing them with a dedicated database, even incorporating data such as dental records. Furthermore, the software is able to compile a psychological profile by using facial analysis.
4-M-79 is Yutani Corporation's program version of the Quiet Eye software. In 2079, Yutani used it to spy on Elizabeth Shaw's video requests to Sir Peter Weyland to fund an expedition to LV-223.
T
Terminators
|
|
|---|
A sentient group mind and artificial general superintelligence system called Skynet went into hiding and came to life in the year c2381. Skynet's new strategy involved fusing kiande amedha DNA into existing Terminators to produce a new generation that was deadlier. The Yautja became involved with Ripley 8 and Annalee Call, and a full-scale conflict breaks out between the 4 parties.
Dr. Trollenberg's genetically altered Terminator faced off against a typical Yautja. The Yautja used his advantage of distance to fire a plasma bolt into the Terminator's chest, causing some endoskeleton and skin damage. With the wristblades, he caused more visible damage. But once the Terminator had the Yautja in his grasp, the conflict was virtually ended. The Terminator emerged triumphant after ripping off the Yautja's arm, smashing him in the face, and blowing the Yautja out of a hole made in the space station.

|---|
- Male synthetic.
Walter is a synthetic crew member of the Covenant in 2104. He is the newer model to the David series, though he bore the same physical model. Unlike the David series, he has the ability to self-repair.
He maintains the ship while the colonists are in cryosleep. When a neutrino flair damages the Covenant, he wakes the crew. Detecting a transmission from an unknown planet, Walter joins the expedition team on the planet. After encountering Neomorphs, one of them bites his hand off. He joins the survivors at David8's base, where he becomes aquainted with David8. Their differences in programming are displayed.
Walter surmisses that David8 killed Shaw, but when he confronts David8, David8 impales him, seemingly destroying him. Walter's systems reboot and he attacks David8. David8 wins, and secretly assumes Walter's identity.
