Cylon (reimagining)

This redirect is about the reimagined Cylons. For Cylon, see Cylon (reimagining) (disambiguation).

Cylons—from Cybernetic Lifeform Node—are a race of sentient machines, created by humans, which appear in the reimagined Battlestar Galactica television series and its prequel spin-off Caprica. They have several different forms, some of which perfectly resemble and even mimic the behavior of humans, while others are more mechanical in appearance and function.

Background

The Cylons of the reimagined series were created by humans, specifically the Twelve Colonies of Kobol, to serve as robotic workers and soldiers. At some point they rebelled and warred against their creators, called the First Cylon War. An armistice was eventually signed, influenced by the arrival of the Final Five, ending the conflict. The Cylons then disappeared for 40 years. During this period, the Cylons evolved into a society with multiple models, including some that are biomechanical in nature and nearly indistinguishable from human beings. After approximately 40 years, the Cylons returned and destroyed the 12 colonies in a surprise attack, called the Second Cylon War, with the survivors pursued relentlessly through deep space.

It is later revealed that humans had also created Cylons on Kobol itself, thousands of years before their creation on the twelve colonies, and that these Cylons were the "thirteenth tribe" that settled the first planet to be named "Earth". This knowledge was lost after the exodus of the tribes from Kobol, and so the people of the colonies believed the mythical thirteenth tribe to have been humans like themselves.

Cylons acknowledge themselves as "humanity's children" but believe their parents are deeply flawed. There are major religious differences between the two groups. Cylons are mostly monotheists while humans predominantly worship a polytheistic pantheon of gods similar to Greco-Roman mythology.

Along with the humanoid models, Cylon society consists of a labor/warrior class of Centurions, and a transport/air warrior class of Basestars and Raiders. Basestars and Raiders are partly biological and as such vulnerable to viral infection. The Raiders, Basestars and Centurions have not been allowed total free will although the Hybrids who control the Basestars seem to have some autonomy and respect among the humanoid Cylons.

The humanoid Cylons are the leaders of the Cylon society and the revelation that these infiltrators can perfectly mimic human form (even down to the cellular level) creates a wave of fear and paranoia among the humans. Some humanoid Cylons are sleeper agents, programmed with false memories so that they think they are human. Cylons can interact with humans very convincingly, even being capable of intimate emotional and sexual relationships. The Cylons are capable of the same psychological and emotional responses as human beings. Nonetheless, they have certain transhuman abilities, such as increased stamina and strength and the ability to physically interface with computer systems. Cylons are more sensitive than humans to some forms of radiation, and more resistant than humans to others. They are also able to upload their memories to other copies of their model through a central station which a Cylon of their model could access if they choose to do so. The humanoid Cylons also have the ability to distinguish between identical-looking copies by sight, which is something the Centurions -and humans- do not.

Reproduction is more difficult, with the Cylons initially unable to produce children from their sexual unions. They decided to turn their attentions to reproduction with humans. Their crossbreeding experiments in facilities called "farms" are also unsuccessful, and they eventually develop a theory that love is necessary for them to procreate, because "God is love" in their theology. This leads to a successful experiment in which a Number Eight and Lieutenant Karl Agathon are set up to fall in love, and produce a daughter named Hera. It has also been revealed that the 13th Tribe was capable of sexual reproduction. They also originally were not capable of sexual reproduction, but learned to do so on the original Earth.

In lieu of sexual reproductions, humanoid Cylons had the ability to download their consciousness into another body when the body they are currently using is killed or destroyed, giving them virtual immortality (until the fourth season episode "The Hub"). The second season explored this notion in greater depth — these downloads have a limited range, requiring the Cylons to build a "Resurrection Ship" to capture them. If not within range of a working Resurrection Ship, a Cylon's death will be permanent. The episode "Scar" established that the downloading process is shared by the semi-organic Raider spacecraft, which allows Raiders who have been killed several times to become more formidable fighters, but the mechanical Centurions do not download. The Resurrection Ships function as boosters for the central Resurrection Hub. If the Hub is destroyed, resurrection ceases for all Cylons.

Cylons also have an ability referred to as "projection", a form of hyper realistic day dreaming which allows them to change the appearance of their surroundings in their own mind (e.g. making the corridors of a ship look like a forest, etc). They have the ability to touch, feel, smell, etc. that fantasy environment. They could even share projections with others and also create third persons that don't exist in the real world as part of the fantasy. This ability serves as a fantasy expression of their subconscious desires or emotional life.

If a Cylon is deemed dangerous by the other models, he or she may be "boxed" — deactivated with their consciousness and memories placed into cold storage. This may involve a particular copy or an entire line. Boxed consciousnesses are stored in the Resurrection Hub and can be restored.

Centurions are often called toasters, partly a reference to their shiny metal construction, but also to suggest that they are descendants of the ordinary household appliance as a way of demeaning them. For that reason, "toaster" has also been used in a derogatory manner towards humanoid Cylons. Another term for human-looking Cylons is "skinjobs" (an homage to the film Blade Runner in which Edward James Olmos has a supporting role). Centurions have been termed "chromejobs" or "bulletheads".

Cylons in the reimagined series differ in a number of ways from those of the original series, including origins and abilities.

History

The origin of the original Cylons has not been revealed in the show as of this writing. It is indicated that resurrection/downloading technology has existed on-and-off since the time of Kobol, but it has not been indicated if Cylons developed the technology on their own or if humans were involved.

The Thirteenth Tribe was a race identified as Cylon. Between 3,000 and 4,000 years prior to the events of the Miniseries, they left Kobol and settled on a planet they dubbed Earth. It is implied that the humans and Cylons of Kobol had a destructive war between them as would happen in the 12 Colonies, but the nature of the possible conflict wasn't explored. Eventually, these Cylons developed the ability to sexually reproduce and resurrection technology fell into disuse and was lost. 2,000 years prior to the miniseries, the "Final Five" began work to redevelop resurrection, having been warned by mysterious "angels" that a disaster possibly similar to the one on Kobol was coming. When Earth was decimated in a nuclear war between the thirteenth tribe of humanoid Cylons and their own mechanical Cylon creations (caused by maltreatment of the mechanical Cylons at the hands of the humanoids), the Final Five managed to download into a vessel that they had prepositioned in orbit around the planet.

The Final Five wanted to warn the humans of the Twelve Colonies to treat their Cylon workers well in order to prevent another catastrophe. However, the Five traveled relatively slowly, at sub-lightspeed, with the journey taking approximately 2,000 years (relative to Earth and other planets outside of the ship while only a few years passed inside the ship). The Earth Cylons, for reasons unknown, never developed Faster Than Light (FTL) propulsion. When they arrived, the Twelve Colonies of Kobol descendants of the original 12 tribes, had already created their own Cylon Centurions which had already revolted from alleged mistreatment and a war was raging as happened on Earth. The Colonies counter-attacked with military force and the first Cylon War commenced, lasting roughly twelve and a half years. The Final Five also learned that the Centurions were trying to develop organic bodies through experimentation on humans, resulting in the first Hybrid. In order to end the war against the humans, the Final Five agreed to assist the Centurions, producing model numbers One to Eight and resurrection technology. The war ended with an armistice and an attempt by the Colonies to establish diplomatic relations between the two warring parties. The Cylons then disappeared and were not seen again by the Colonies for another forty years despite the annual dispatching of a Colonial representative to a space station that had been purpose-built to serve as neutral territory for diplomatic meetings.

The first of the organic Cylons, John Cavil, refused to let their creators' care for humanity blind them. He suffocated the Final Five and boxed their memories before they were resurrected. He then periodically sent them to the Colonies so that they would see how terrible humanity was.

Having not heard from the Cylons in forty years, the colonial admiralty became suspicious and sent the battlestar Valkyrie on a covert mission close to the armistice line to gather intelligence on Cylon activity. A stealth ship from the Valkyrie crossed the armistice line and the pilot was captured by the Cylons. Three years later, perhaps in retaliation, the Cylons initiated a nuclear surprise attack on the twelve colonial homeworlds simultaneously. The attack was successful because a Cylon infiltration agent, later to be known as Caprica Six, infiltrated the colonial defense network on Caprica with the unknowing complicity of renowned Colonial scientist Gaius Baltar and created backdoor programs to shut the network and its defenses down. The attacks wiped out billions of humans, nearly the entire colonial population. Two Battlestars, the Galactica and the Pegasus, managed to escape the massacre due to their systems either being non-networked or offline. The others were destroyed when their systems went offline during the attacks. A fleet of civilian ships were also left scattered throughout the neighboring vicinity of space. All told there were only a bit over 50,000 humans left that weren't killed outright in the attack, stuck on ships that were left behind, or trapped on the Cylon-occupied Colonial worlds.

Following their victory, the Cylons began pursuit of a fleet of civilian ships led by the Galactica as well as initiating the next phase of their evolution, procreation. Female human survivors on the planet Caprica and perhaps other Colonial worlds, were detained and used in experiments to create Cylon-human hybrids. It is possible the surviving men also were subject to similar experimentation but were never indicated. The experiments were unsuccessful and the Cylons believed that the missing component in their attempts at procreation was love. They tested this by using a Number Eight posing as Lt. Sharon “Boomer” Valerii from the battlestar Galactica to seduce a marooned Galactica officer, Lt. Karl “Helo” Agathon, on Caprica. As planned, Helo fell in love with this copy. This copy of Number Eight also fell in love with Helo and turned her back on the Cylons, knowing that Helo would never agree to stay on Caprica. She defied orders to kill him if he didn't agree to do so, helping Helo to escape the planet. The couple produced the first viable human/Cylon pregnancy. This Eight would go to the fleet with Helo. After a approximately a year's imprisonment on Galactica she would slowly gain the trust of Commander Adama and the other Galactica crew. She would later marry Helo, join the Colonial military and receive the call sign of "Athena" from a mostly accepting crew.

Ten months after the initial attacks, the Number Eight from Galactica, Sharon Valerii who had the call sign of "Boomer", attempted to assassinate Commander Adama under the influence of internal programing unknown to her. Being a sleeper agent, she at the time didn't know she was a Cylon but had a dreaded suspicion after suffering from unexplained blackouts that came during attempts of sabotage on the Galactica. She was killed by an vengeful crewmate Cally Henderson and downloaded into a new body. She settled on the now Cylon-occupied Caprica including in her former apartment, not being able to relinquish her human identity for some time. She, along with Caprica-Six, then began leading a Cylon campaign for better treatment of the humans. The word of these two Cylons considered "war heroes" by the others, carried weight. The newly educated Cylons determined their actions to be a mistake, going against God's will and ideals of love and compassion and withdrew from the colonial home worlds and promising a more benevolent treatment policy toward the humans and as, Sharon Valerii hoped, reconciliation.

During this time, the half-human, half-Cylon hybrid, Hera Agathon was born on Galactica but fearing the outcome of the Cylons potentially capturing the child, President Laura Roslin faked Hera's death and secretly had her adopted out to a human woman within the fleet. Shortly after, the humans found a nearly barren but habitable world hidden in a nebula. They settled on the planet they would dub New Caprica.

The human/Cylon separation lasted a year before the Cylons traced the radiation signature from a nuclear explosion indirectly and unintentionally caused by Gaius Baltar (in a fit of pique over a condescending letter from Laura Roslin, he gave a nuclear device to Gina, a Number Six type Cylon) back to that planet. The Cylons decided to occupy the new human settlement under their benevolent control, at first peacefully as per their new policy but later forcefully as human Resistance increased and with viciousness. They in the end started to use punitive methods to keep the humans in line including summary executions and infiltration of the Resistance by seemingly sympathetic Cylons, including an Eight model that manipulated Felix Gaeta into giving her a list of people the Resistance desired to be set free from Cylon detention, she then unknowingly to Gaeta, had most of them killed for being important to the humans enough to be asked for.

Four months later the colonials were able to escape from the Cylons with the help of an insurgence movement and the efforts of both the battlestars Galactica and Pegasus, though not without a very large loss of life. The escape could not have occurred without the indispensable help of Caprica Sharon, the same Eight model that earned the trust of Admiral Adama and was sworn into the Colonial Military. She was able to access the Cylon facility the keys to the various Colonial spacecraft that were on the surface of the planet and was necessary for the mass escape of the humans. Prior to this a Number Three, having spoken with a human oracle was told that Hera was alive and somewhere on the planet. She managed to rescue Hera after her adoptive mother was killed during the escape.

Having failed at their occupation, the Cylons then adopted the colonials’ mission to find the home of the fabled thirteenth tribe, a planet called Earth, with the intent of making it their new home. They resumed pursuit of the fleet but upon reaching the Lion's Head Nebula, dispatched a Basestar to investigate. The Basestar took onboard a canister left by the thirteenth tribe. The canister was found to contain an airborne virus that proved highly contagious and deadly to the Cylons, yet had no effect on humans. The virus was also found to be capable of accompanying a Cylon during the download process so the Basestar that had been dispatched for the investigation was abandoned by the rest of the Cylon fleet for fear that any rescue would contaminate the entire Cylon fleet. The colonial fleet soon thereafter discovered the disabled Basestar and sent its own investigative team on a Raptor and captured a small number of ailing Cylons. The colonial fleet attempted to use the virus to wipe out the Cylons but the plan was defeated when Helo, repulsed by the potential genocide and the possibility of innocent Cylons like his wife who had no ill will against humans also being killed, had the captive Cylons killed before they were within range of a resurrection ship.

Meanwhile Sharon "Boomer" Valerii after the disappointment of the occupation of new Caprica started to turn increasingly Anti human. She was charged with the care of Athena's daughter Hera but Hera rejected her. Boomer during a truce negations with the Galactica told Athena that her daughter is alive but sick on the Baseship. She also invites Athena to come to the Baseship and rejoin her people for the occupation showed that humans and Cylons will never get along and that the Humans would never truly accept her despite her position. Later, desperate for her child, she convinces her husband Helo to shoot and kill her so she could resurrect on the Cylon Baseship. Once there, she retrieved Hera with the help of Caprica Six who killed a hate filled Boomer to prevent her from killing the child. She had tried to prevent Athena from taking Hera back to the humans and declared that Cylons were never meant to have children in reference to the Cylons' inability to reproduce naturally and perhaps in pain over her knowledge that she would never have children like Athena, despite Boomer's projection of her imaginary daughter she desperately wanted. Caprica Six returned with Athena and was detained by Adama in Athena's old cell.

As the pursuit continued, internal relations between the Cylons began to break down. A Number Three violated her programming by actively seeking information about the final five models including seeing a vision of them on the Algae Planet where the Colonials stopped to get food stores. From that she was able to identify them. This resulted in her and her entire line being "boxed", i.e. all copies pulled from active service and their consciousness stored in cold storage. Within the fleet, A strange music like activation signal was being received by the Final Five Cylons bewildering them and in some cases leaving them disoriented and physically sick. It soon became apparent to each other that Saul Tigh, Samuel Anders, Galen Tyrol and Tory Foster were actually Cylons themselves (four of the final five) when they simultaneously became aware of their origins after hearing the same music in their minds, drawing them to each other. They then, much like Sharon Valerii before them had to come to terms that they weren't human after all but members of the hated Cylon race. They coped in their own ways but didn't dare tell anyone of their self discovery. Saul Tigh pledged fierce loyalty to the humans in general and Admiral Adama in particular rejecting his Cylon nature. Anders also remained loyal to the humans willing to fight and possibly die in battle for them even while knowing he would be rejected by most of them despite the acceptance of Athena. Tyrol and Foster were ambivalent with Tyrol having pro human leanings but wondering what it was like to be a Cylon and was more accepting of his nature. Foster became increasingly more anti human and accepted the darkside of being a Cylon. After their activation the fleet came under attack but a Cylon Raider during battle identified Anders and he and his fellow Raiders broke off the attack, refusing to fight.

This set off a debate in the Cylon governance regarding the failure of the Raiders to fight. The Number Ones, Fours, and Fives voted to "lobotomize" the Raiders to make them more quiescent and compliant with instructions. The Twos, Sixes and Eights, lead principally by a very assertive Number Six named Natalie, convinced that the Raiders had sensed the presence of the Final Five, voted against this measure but lost their vote against having the Raiders reconfigured when the 3-3 tie was broken after a single Eight (Boomer) voted against her model, something which had never been done before. After the disaster of New Caprica, the rejection of Hera and the rejection of her by the humans Boomer had become very anti human. In addition it was jealousy as a motive. She saw Athena as having every thing she coveted, including a husband, a child and a home as makeshift as it was. She had turned to John Cavil for acceptance, comfort and to be a better machine as Cavil insisted that Cylons were and to stop aspiring to be like humans whom he hated and sought out their deaths. He was a key cause of the Cylon attack on the humans and avocated wiping them out. He was the one responsible for killing the Final Five and blocking their true memories in the belief they would see who the humans really were. By siding with the Ones, Fours and Fives Boomer broke the deadlock. In frustration over the legal trick, Natalie retaliated by removing inhibitor circuitry from the Centurions, granting them free will and independent thought. The Centurions then sought retribution against the models who were “lobotomizing” the Raiders and killed them.

Centurions

The Cylon Centurion is the basic infantry ground unit, deliberately made less intelligent than human models, and are believed to be entirely mechanical. Centurions retain the silver appearance, robotic body, helmet-like head, and oscillating red bar eye of their counterparts from the original series, but are larger, taller, stronger, more agile, and have a more streamlined appearance. They also have retractable guns built into their lower arms, bladed fingertips, and are often heavily armored.

Earlier model

The Battlestar Galactica miniseries has an older model Centurion on display in Galactica's museum hangar, which bears a striking resemblance to the Centurions of the 1978 series.

In Battlestar Galactica: Razor, Centurions in the original Cylon war are shown. These Centurions are almost identical to those from the original series, except they are CGI.

In "Sometimes a Great Notion", it is revealed that on the planet called Earth mechanical Cylon Centurions similar to, but unlike previously known models, were present. Earth was devastated by nuclear war 2,000 years before the series' events, but it has been implied the centurions were responsible. In Part 2 of "Daybreak", older-model Centurions are among those seen defending the Cylon colony from an assault by combined Colonial and rebel Cylon forces.

In the pilot of Caprica, the very first colonial centurion is seen and is identified as a 'Cybernetic Lifeform Node', which abbreviated coins the word 'Cylon'. It contains a copy of the consciousness of technology CEO Daniel Graystone's dead daughter Zoe Graystone, a secret monotheist.

The Centurions experimented with creating humanoid Cylons on their own near the end of the war, carving up human prisoners in the process, but succeeded only in creating the Hybrids. Because Hybrids require cybernetic support to live, this was considered an evolutionary dead end. The Final Five assisted the Centurions in creating fully humanoid Cylons, complete with the thirteenth tribe's ability to resurrect, in exchange for ending the war with humanity. The Centurions were monotheists who believed in a loving God, a belief which the Final Five adopted and which was passed on to their "children".

Current model

Unlike in the original series, these Centurions seem to be constructed without the means to simulate human speech, making them mute. While the Centurions most likely communicate between themselves by non-speech systems, and are shown responding to verbal commands from the humanoid Cylons, how extensively the two different types of Cylons are able to communicate with each other remains unrevealed.

Screenwriter Ronald D. Moore has commented on his blog that these new Cylon Centurions do not download into new bodies when they are destroyed, though in the Season 2 episode "Scar" it is stated that the Raiders do, in order to preserve their flight training and experience. Based on a comment by an Eight (Galactica Athena) in the episode "Torn" the Hybrids have something to do with the programming of the Centurions. She states that when the virus infected the Hybrid on the infected Basestar, it caused the Centurions to shut down; however, several instances show that Centurions can function independently even when no Basestars or humanoid models are there to command them. In the episode "Faith," a Centurion immediately fires upon an Eight model when she unplugs a Hybrid—it is unclear whether it did this in willful defiance of the Hybrid, in accordance with some higher programming, to trigger the transformation of the Eight that resulted from the shooting, or a result of the removal of their higher function inhibitor modules (occurred in "Six of One"). As of now, the extent of the connection between the Centurions and the Hybrids has not been fully explored.

In "Six of One", after the Raiders showed signs of free will, the Twos, the Sixes, and the Eights with the exception of Boomer voted against a decision to reconfigure the Raiders, considering it an act of lobotomy. Outvoted, they removed the inhibitor modules from the Centurions that restrict higher functions, granting the Centurions independent thought. Although still largely servile, the Centurions were shown to exhibit mild versions of human behaviour, such as politeness and consideration (such as responding to the word "please"). The newly freed Centurions sought retribution on the Cylons who decided to lobotomize the Raiders.

At the end of the series the sentient Centurions are given their own baseship by the humanoid models and set out to find their own destiny.

Cylon Raiders

Main article: Cylon Raider

The current form of Cylon Raiders are biomechanical Cylons in the form of small fighter spacecraft, and are also resurrected when they die. Raiders are subservient, and have been compared to trained animals by the humanoid Cylons. A Cylon Raider nicknamed "Scar" was shown to have developed a personality, in the episode of the same name. Scar was the Cylons' top gun, driven by a bitter hatred of humans after having been killed and reborn many times. Raiders do not use any form of vocal communication.

The original Cylon Raiders from the First Cylon War were larger spacecraft driven by Centurion pilots, and not alive themselves. The modern Raiders do not have pilots, nor space for them.

Humanoid Cylons

Although they made only a single appearance in the original continuity (the episode "The Night the Cylons Landed" from Galactica 1980) humanoid Cylons play a major part in the reimagining. The term 'humanoid Cylon' is a description, rather than an official designation. These beings are usually just known as "the Cylons", or derogatorily as "skinjobs" or "toasters". These Cylons not only look like human beings externally, their bodies are made of flesh and blood rather than metal.

The Cylons have nonverbal ways of sharing information but do not have a hive mind, even among the identical duplicates, and are most often shown talking to one another. There are twelve distinct humanoid models in existence, which are divided into the "Final Five" and "Significant Seven" (the latter term is only used by the Battlestar Galactica producers). The "Final Five" are unique, and are the last survivors of the thirteenth tribe. They developed the many copies of the "Significant Seven" in conjunction with the Centurions of the Twelve Colonies. Each copy shares basic traits with the rest of their model, but they can develop into distinct individuals.

Cylon society is made up of the seven surviving known, mass-produced humanoid models - Numbers One, Two, Three, Four, Five, Six, and Eight. The Number Seven model (the "Daniel" series) was destroyed by the Number One model (the "Brother John Cavil" series) decades prior to the destruction of the twelve colonies. The Final Five were killed, and temporarily boxed, by Number One, who then purged their memories and sent them to live among the humans. The remaining six models had no knowledge of the Final Five's identities, presumably blocked by Brother Cavil, though they were aware of the existence of five absent models not to be spoken of. When D'Anna (Three) attempts to learn their identities, her entire model is boxed — indefinitely deactivated with their memories permanently downloaded into cold storage — as punishment by the other six models. In the final episode of the third season, four of the final five are revealed to be "human" characters with long histories on the Galactica. Their purpose, and how and why they were hidden from the rest of their kind, is a major plot point of the fourth and final season. In the fourth season, Ellen Tigh is revealed to be another of the "Final Five".

The humanoid Cylons are responsible for command decisions. While the command structure has not been fully explored, some hints at organization have been revealed. At the end of the miniseries, a group of Cylons are debating what to do, and one speaks authoritatively, to which another responds, "by your command", a reference to the original series. Other forms of Cylon, such as the Centurions, the Raiders and the Hybrids, appear to have little or no policy-making role within their society—to the point that the humanoid Cylons can freely impose blocks on their behavior and cognitive programming. Although the Cylons consisted originally of early-model Centurions fighting for freedom from slavery by humans, by the time of the series they are entirely subservient to their own humanoid creations. Later in the series, these restrictions are loosened within the "rebel" Cylon group; Centurions are occasionally depicted as resisting authority.

In the episode "Precipice", a Cylon council (made up of multiple copies of several models) appears to cast votes collectively by model, indicating that model plays an important role in the hierarchy of Cylon society and that they always make decisions in this fashion, as Cylons of the same model are implied to have higher or lower ranks than Cylons of other models at various times. It was also shown during the occupation of New Caprica, that a select group of humanoid Cylons, mostly ones who had been within the Colonies, such as Boomer and Caprica Six, seemed to have seniority within their own model. One of each model was seen deliberating and discussing their course of action, with each of the 'senior' models representing the opinion of their entire model group. The Number Ones subvert consensus by undertaking many actions without the knowledge or consent of their siblings, such as turning against the Number Sevens and the Final Five, and then reprogramming their siblings to hide this.

Although little is known about Cylon psychology, it is clear that they share many of the same emotional vulnerabilities that humans possess. This is evidenced by Gina's catatonic state as a result of the severe trauma of her abuse at the hands of the Pegasus crew. This abuse was presented in the form of multiple sexual assaults, battery, starvation and outright torture. Number Six/Caprica Six also revealed that Cylons exist by 'projecting' an environment of their choice on the real/physical world.

Number One (John Cavil)

Main article: John Cavil

The main antagonist of the series, John Cavil first appears on Galactica in the two-part episode "Lay Down Your Burdens", posing as a priest. His true identity is revealed when a second copy boards Galactica and reveals his Cylon nature. Cavil's role in society is one of contradictions and occasionally serves as a devil's advocate, pointing out the absurdity of his fellow Cylons and their religious zealotry. He was revealed to be the 1st model in the episode "Six of One".

Despite his talk of religion and his alter-ego as a priest, Cavil has a sadistic, cruel and Machiavellian streak in his personality which none of the other Cylon models share (going so far as to torture Saul Tigh by gouging out one of his eyes and showing it to him). He also took exquisite pleasure blackmailing Saul's wife (Ellen Tigh) into providing sexual favours in exchange for releasing her husband Saul from Cylon captivity on New Caprica. Cavil is also an atheist (the only one of the seven models who is one), and will often mockingly make quotation signs with his hands when saying the word "God". His opinions of humans are also driven by contradictions; despite being one of the most violently anti-human Cylon model, as well as advocating a policy of culling humanity down to a "controllable number", Cavil claimed to have been against the destruction of the Twelve Colonies and advocates a unique Cylon Society, not one that emulates its creators. After finally arranging Colonel Tigh's release, Cavil manipulated the situation even further by again blackmailing Ellen Tigh to betray the human resistance on New Caprica and threatening to kill her husband if she did not comply.

Cavil is portrayed as being aloof compared to the other models, though it has been implied by Cylon Model 8 "Boomer" that Cavil has begun mentoring her with his philosophy regarding Cylons not emulating humanity. Cavil is aware of aspects of Cylon lore that the others models are not aware of; his knowledge of the "final five" led to him "boxing" Cylon Model Three D'Anna (as well as all other Number Threes) in order to ensure that whatever information about the Final Five she gained were "boxed" with her.

It is revealed in the fourth season that he and the other seven Cylon models were created by Ellen Tigh and the other four final five Cylons, and he was made in her father's image, as well as being given the name "John" by her. He hates this name and shows deep resentment towards Ellen at being 'limited' by having to live in a human-like body.

Cavil (John) was the first Humanoid Cylon created by the Final Five. Cavil with the help of the Final Five created the other seven humanoid Cylons. Therefore Cavil knew about the Final Five all along. The Final Five showed the Centurions how to make Humanoid Cylons in attempt to give them human characteristics (love, mercy). The Final Five thought that these characteristics would prevent the same type of war that occurred on the thirteenth colony (the original Earth). For some reason, Cavil rejected the human trait of mercy and turned against the Final Five. Before the war on Caprica started, Cavil killed the Final Five by putting them in a compartment and then cutting off their oxygen. When the Final Five were resurrected and unboxed, John wiped their memories and implanted new memories for their life in the Twelve Colonies.

Number Ones are played by Dean Stockwell.

Number Two (Leoben Conoy)

Main article: Leoben Conoy

Leoben first appears as a smuggler at the munitions depot at Ragnar Anchorage, where he was exposed as a Cylon in the mini-series. The Leoben model Cylons are known for their religious zealotry, which is intertwined with a pathological, and sometimes sexual, obsession with Starbuck. He was revealed to be the 2nd model in the episode "Six of One".

Like his fellow Cylons, the Leoben models are skilled at deception and deceit. This was most notably seen when he manipulated Starbuck into thinking that a young girl he had kidnapped on New Caprica was her biological daughter. The Leoben models are known for their cunning minds and ability to find and exploit the weaknesses of others. As such, they are known to mix truth with their lies in order to better manipulate their victims. Unlike his fellows, he appears to have the ability of prescience and has on several occasions prophesied future events.

Number Twos are played by Callum Keith Rennie.

Number Three (D'Anna Biers)

Main article: Number Three (Battlestar Galactica)

The Number Three model first appeared in the episode "Final Cut", as D'Anna Biers a reporter for the Fleet News Service, who is asked by President Roslin and Commander Adama to create a propaganda-type documentary to ease tension between the fleet and the military forces aboard Galactica. In truth, the Biers model used the documentary as a means to relay information regarding the Cylon Sharon being alive to her fellow Cylons back on Caprica. She was revealed to be the 3rd model in the episode "Downloaded".

The Number Three Cylons are among the more aggressive Cylons of the seven models, as well as sharing a fate-based understanding toward the Cylon religion, believing that everything that happens is the will of God. Their religious devotion masks a deep questioning by Number Threes (in particular, the D'Anna Biers model) about why bad things are allowed to happen by God.

The Number Threes possess an "alpha-female" type aggressiveness, almost always forcing themselves upon other Cylons as the de facto leader in any situation that the Cylons engage in. They are often rivals of the Number One and Number Six models. The rivalry with the Sixes partly stems from when Caprica-Six beat one of the Number Threes to death to save Samuel Anders from being tortured and killed. D'Anna and Caprica-Six later reconcile and both of them are involved in a relationship with Gaius Baltar without any initial conflict. Baltar seduces D'Anna by exploring her crisis of faith, which leads to her secretly committing suicide (a major taboo in Cylon society) in order to go through the process of resurrection. She feels these near-death experiences will answer the burning questions regarding her faith, most notably the identity of the final five Cylons. This culminates in the episode "Rapture" in which D'Anna sees the faces of the Final Five (apologizing to one of them). Unfortunately, as she does so, the other Cylons voted to "box" not only D'Anna but also the entire Number Three line. Cavil, the Cylon who carried out the "boxing", revealed to D'Anna that she was being silenced because of what she saw regarding the final five and that her memories would be kept in "cold storage" as a result. D'Anna, but none of the other Threes, is unboxed in the 4th season episode "The Hub".

The Number Threes are also amongst the more anti-human Cylons, though for practical reasons: in "Exodus" Part II, D'Anna tells Baltar that she believes that humanity must die if only to prevent future generations of humans from seeking revenge against the Cylons for their acts of genocide and oppression against humanity. She is temporarily the leader of the "rebel" faction of Cylons which makes peace with the human fleet, but when the first Earth is found to be a devastated ruin, she decides to stay behind there and die rather than continuing to be part of the cycle of death, exodus, and rebirth.

Number Threes are played by Lucy Lawless.

Number Four (Simon)

Main article: Number Four (Battlestar Galactica)

Simon first appears in the episode "The Farm", posing as a human physician treating Starbuck for a gunshot wound in what was supposedly a resistance hospital on Caprica. In reality this was a Cylon "farm" set up to breed human-Cylon hybrids using captured humans, and he was also performing invasive tests on her reproductive organs. After Starbuck begins to suspect Simon's true nature and kills him, she escapes from the facility, her fears confirmed when a second copy of the model greets her on her way. He was revealed to be the 4th model in the episode "Six of One". Fours are consistently the Cylons' medical specialists.

Number Fours are played by Rick Worthy.

Number Five (Aaron Doral)

Main article: Number Five (Battlestar Galactica)

In the miniseries, Doral appears as a public relations worker for the abortive Battlestar Galactica museum. In the episode "Litmus", another copy of Doral sneaks on board the Galactica and detonates an explosive. This event prompts the fleet-wide announcement that Cylons can have a human appearance. He was revealed to be the 5th model in the episode "Downloaded".

During the Occupation of New Caprica, the Fives seem to be one of the most anti-human and aggressive models. As a series, the Fives seem to specialise in public relations and control, using large scale events and media manipulation to their advantage.

Number Fives are played by Matthew Bennett.

Number Six (Caprica-Six / Head Six / Shelley Godfrey / Gina Inviere / Natalie / Sonja)

Main article: Number Six (Battlestar Galactica)

The first model explicitly revealed to be a Cylon in the miniseries, the Sixes often use seduction to their advantage. Important copies include Shelly Godfrey, Gina Inviere, Head Six, Caprica Six, and Natalie.

One of the models, later known as Caprica Six, on her way to meet with Dr. Gaius Baltar, murdered an infant by breaking its neck. This could either be considered sociopathic, or a mercy killing due to the coming Cylon attack. She went on to save Baltar's life when his house was struck by a blast wave from the Cylon attack on Caprica.

Caprica Six has a love-hate relationship with Gaius Baltar, alternately defending him to other Cylon models or leaving him to suffer at their hands and progressing to reinitiating a sexual relationship with him.

Another Number Six, Gina, acted as a contractor for the Battlestar Pegasus and was in a relationship with Admiral Cain. When Cain discovered that Gina was a Cylon agent, she ordered her crew to "push her programming" in an attempt to see if Gina was vulnerable to emotional trauma. Gina later escaped with Baltar's aid, assassinated Cain, and founded a resistance group in the fleet, preaching peace with the Cylons. While it seemed that Gina may have developed feelings for Baltar and was going to pursue a relationship with him, she detonated a nuke (provided by Baltar) which destroyed Cloud Nine, some other fleet ships, and acted as a beacon for the Cylon fleet to locate the human fleet on New Caprica.

A reincarnation of Baltar's Six (named Caprica Six by the others) committed the second incident of Cylon-on-Cylon violence in their history (the first being Sharon "Athena" Agathon killing a copy of another Number Eight on Caprica earlier in the series to save Karl Agathon), killing a Number Three in order to save the life of Samuel Anders, who himself was later discovered to be a Cylon.

With Caprica Six imprisoned on Galactica after helping a Sharon (Number Eight) escape from the Cylons with Hera, she offered to testify against Dr. Baltar. While in the brig, she has a relationship with Saul Tigh that results in the first Cylon-Cylon pregnancy.

It should also be noted that Caprica Six has a "Head Baltar" which only she sees similar to how Baltar has a "Head Six" that only he can see; Head Baltar serves as a sort of conscience for Caprica Six, but also an advisor in times of trouble or danger, much the same role that Head Six plays for Baltar. This Head Baltar, has also appeared at least once to Baltar himself. Before the true nature of both Head Baltar and Head Six was revealed, there had been rampant speculation that Baltar was a Cylon. In the series finale, both Head Baltar and Head Six turned out to be divine beings (actually referred to as "Angels") manipulating both the Colonials and Cylons into fulfilling "God's plan".

Number Sixes are played by Tricia Helfer.

Number Seven (Daniel)

Main article: Number Seven (Battlestar Galactica)

Daniel was the seventh Cylon model created by the final five. Ellen referred to Daniel as an "artist and so sensitive to the world". She was very close to Daniel, which enraged Cavil; he felt that Daniel was Ellen's favorite child and became jealous. Cavil poisoned the amniotic fluid being used to mature the Daniel copies and then corrupted Daniel's genetic code. This sabotage meant that no further Daniel copies could be created - an elimination more permanent than the later model-wide boxing of the Number Threes. The Sevens were not mentioned again during Battlestar Galactica's remaining episodes. Because of the destruction of this model line, there were twelve models active throughout the series rather than thirteen.

Because of the nature of the character(s), fans began to speculate that Kara Thrace was a version of the corrupted Seven line, or that her father was. Ronald D. Moore stated in the podcast for "Islanded in a Stream of Stars" that Daniel is merely a plot device to explain the missing number and to expand on Cavil's character (noting that Daniel is essentially the Abel to Cavil's Cain). In the podcast for "No Exit", Moore described the Sevens as a springboard for Caprica, the upcoming BSG prequel, where "Daniel" is the name of a main character played by Eric Stoltz; this Daniel is the creator of the Colonial Centurions.

Number Sevens are never seen in the series, and therefore not played by any actor.

Number Eight (Sharon "Boomer" Valerii / Sharon "Athena" Agathon)

Main article: Number Eight (Battlestar Galactica)

Sharon "Boomer" Valerii first appears as a Raptor pilot aboard the Galactica. Her true nature as a Cylon was only revealed at the end of the miniseries, and the series quickly establishes that Sharon acted as a sleeper agent, unaware of her true nature and programmed to carry out attacks on the fleet without her human side realizing what she was doing. She was revealed to be the 8th model in the episode "Downloaded".

The other significant copy of this model, Sharon "Athena" Agathon, married Karl "Helo" Agathon, rebelled against the Cylons and joined forces with the Colonials. Her child with Helo, a daughter named Hera, is the first Cylon/human hybrid to be born. Such a child is the subject of a Cylon prophecy and therefore very important as it was a 'child born of love'. Shortly after Hera's birth, Laura Roslin decides to mislead the Cylons into believing the child has died. Her plan involves lying to Athena and Helo, and giving the child to an adoptive mother, Maya. During the exodus from New Caprica, Maya is killed and the baby is found by a Number Three. Number Three later informs Athena that Hera is still alive, but believing it is a ruse, Athena kneecaps her. She is later told the same thing again by Boomer. Athena has Helo kill her, allowing her to download into a new body within the Cylon fleet. With the help of Caprica Six, she manages to rescue Hera and return to Galactica.

This model has been described as "weak" by Baltar's vision of Number Six, and Number Eights usually appear more compassionate and sympathetic than other Cylons. However, they fully supported the destruction of the Twelve Colonies; and the actions in particular of Boomer and an Eight who had a duplicitous affair with Felix Gaeta on New Caprica make it clear that Eights are capable of homicide and betrayal.

Number Eights are played by Grace Park.

The "Final Five" Humanoid Cylons (Samuel Anders, Galen Tyrol, Tory Foster, Saul Tigh, Ellen Tigh)

File:Battlestar Galactica 3x10 The Passage - Final Five.jpg

The "Final Five" Cylons drawn in a crude sketch by Number Three

In the episode "Torn", Gaius Baltar questions Number Six as to why only seven humanoid models appeared on New Caprica and why he has seen only these same seven aboard the Basestar when she had told him previously that there were twelve models. Six replies that the Cylons do not talk about the other five models. Baltar has become worried that he may in fact be a Cylon himself and presses her on whether she would recognize one of the "Final Five", as he names them. Their conversation ends abruptly, leaving the truth of the other models unknown.

In the episode "Hero", Number Three has a dream immediately after she dies, where she sees five glowing figures. Later, in the episode "The Passage", she tries to hold on to the memory of their faces and draws pictures of them soon after downloading, but the memories fade and the drawings are too surrealistic to be of practical use. It's clear that she does not consciously know what the Final Five look like. In the episode "Rapture", D'Anna and Baltar reach the Eye of Jupiter and D'Anna receives a vision of the Final Five. She seems to recognize one of them, but the vision is cut short before the viewers see any detail of the figures. The shock kills her and upon awakening after downloading, she mentions her experience to Cavil. He confirms that the seven known Cylon models do not know who the Final Five are and that the pursuit of that information is strictly forbidden by their programming. As punishment for this and for other acts, Cavil then terminates her and her entire model is "boxed", taking the secret of the Final Five with her until she is unboxed.

In "Crossroads", four of the final five Cylons are revealed to themselves, each other, and the audience, though not to the human characters. Samuel T. Anders, Galen Tyrol, Tory Foster, and Saul Tigh begin hearing the same hallucinatory music that no one else can perceive (a version of "All Along the Watchtower"). When the music draws them towards each other, a "switch goes off" in their minds and they realize that they are all Cylons. They resolve, nevertheless, to continue doing their duty as part of the fleet. The identity of the fifth and final Cylon remains unknown even to them. Their "awakening" seems to affect other Cylons as well, as in the episode "He That Believeth In Me", a Cylon Raider scans Anders then disengages the attack; in the same episode, aboard Galactica, Caprica Six tells Roslin that she can feel the Final Five and that they are near. It is later revealed in "Six of One" that the Twos, Sixes and Eights believe that the Raiders called off the attack because they sensed the Final Five, something the Ones, Fours, and Fives disagree with. Cavil further claims that their original programmers programmed the seven Cylon models not to seek that information out. This disagreement leads directly to the Cylon Civil War, in which the Twos, Sixes, and Eights become known as the rebel faction. In "Revelations", an unboxed D'Anna reveals that only four of the Final Five are within the Colonial Fleet, and confirms that Tigh, Tyrol, Anders, and Tory are those four Cylons. A standoff between Galactica and the rebel Baseship results in the four being exposed as Cylons to the rest of the human Fleet, but Lee Adama, in his capacity as acting President, grants them amnesty as part of an alliance between the Fleet and the rebel Cylons.

Ronald D. Moore confirmed in an interview that the four are indeed fully Cylon — although "fundamentally different" from the others. Moore has also stated that unlike the other Humanoid Cylon models, the Final Five do not have model numbers. This is because in their original lives they were born to (Cylon) parents through sexual reproduction, rather than being built.

In "Sometimes a Great Notion", it is revealed that all of the Final Five had previous lives on Earth, 2000 years in the past. As each of them explores the ruins, each begins to regain small memory fragments of their past lives. It is when Saul Tigh remembers a snippet of his previous life that he discovers that his late wife, Ellen Tigh, must be the fifth and final Cylon, because she was present on Earth 2000 years ago as well. During Saul's flashback, his wife insinuates that she had foreknowledge of the destruction of Earth when she states that plans have been made for her and Saul to be re-born.

In "No Exit" Ellen Tigh is revealed to have resurrected on board one of Cavil's Basestars after her poisoning. The past of the Final Five is also revealed: they lived on Earth 2,000 years ago and were researchers in rebuilding Cylon Resurrection Technology which had been abandoned when the Thirteenth Tribe gained the ability to procreate. Saul and Ellen were married even back then and Tyrol and Tory Foster were in love with plans to get married. They learned of the upcoming holocaust from beings only they could see and worked to rebuild resurrection. They succeeded and placed it on a ship which they left in orbit of Earth. When the nuclear attack happened (according to the writers, an uprising of their own Centurions that apparently destroyed both sides) and they were killed, they were reborn in new bodies on that ship in orbit. The Five then headed for the Colonies to warn them about making artificial life, but the trip took thousands of years due to there being no FTL drive on their ship. Due to traveling at near light speed, time dilation made it seem like less than that to them. They arrived during the first war and made a deal with the Centurions: stop the war and they would help them build human bodies. Thus the Final Five ended the First Cylon War. They built Number One (Cavil) and he helped them build seven other models, but after Ellen began to favour Number Seven, Cavil permanently destroyed the Number Seven line by contaminating the production. Ultimately Cavil locked the Final Five in a compartment and evacuated the oxygen, killing them. He then boxed them and apparently removed the memory of their identities from the other Cylons. He later unboxed and resurrected them, but first blocked their true memories and implanted false ones. Cavil periodically seeded them among the human populations starting with Saul, and eventually Ellen, to show them how bad humanity supposedly was. This shows that Cavil's claim that not seeking out the Final Five was a directive from the original programmers was a lie, and that he was only pretending not to be aware of their identities himself.

Of the Five, two were killed. Tyrol strangled Tory and broke her neck, killing her in revenge for killing Cally, while Anders died when he piloted Galactica and her fleet into the Sun, destroying them as part of a last action to allow humanity to rebuild from the beginning. As the Resurrection Hub had been destroyed by this point, these deaths were permanent.

Hybrids

Main article: Cylon Basestar § The Hybrid

The Hybrids resemble human beings inside an immersion tank similar to a Cylon rebirthing tank. The Hybrids do not have a completely human body, but rather appear to be more like cyborgs, consisting of conduits and other connectors mated to, or in place of elements of their bodies. The Hybrid is not one of the "twelve models" of humanoid Cylon, but is a separate model that effectively further bridges the gap from primarily mechanical Centurion, to partially bio-mechanical Raider, to Hybrid, to humanoid Cylon. They are similar to the autonomous bio-mechanical pilots within Raiders, specially constructed as living computers that manage the autonomic functions of the basestar, including navigation and FTL jumps and climate control. The Hybrids are so integrated into the basestar's functionality that they are, for all practical purposes, the basestar itself.

In addition, the Hybrids continually speak what most of the humanoid Cylons consider to be gibberish, although there is some difference of opinion on this point. Many Cylons believe a hybrid's conscious mind is completely mad and the functions it performs are part of a deeper state of mind in connection with the ship. Caprica Six states that the Leoben Conoy models believe that every word a hybrid says is channeled from the Cylon god. A Hybrid is not allowed a vote in the Cylon democratic process by the humanoids, though it sometimes objects to the course of action they take, for example, leaving another basestar full of disease-infected Cylons to their fates.

In Battlestar Galactica: Razor another Hybrid is seen. This Hybrid, considered the First Hybrid in Cylon lore, was the result of experiments on humans during the first Cylon war and appears to be more coherent and prophetic than the other Hybrids. It went rogue as early as the end of the First War, and is protected by model 0005 Cylons called Guardians, who presumably consider it their god. According to the humanoid Cylons, the very existence the First Hybrid and its Guardians was considered more of a legend. The Colonial Fleet accidentally clashes with the Guardians and manages to destroy them and First Hybrid along with its basestar. The First Hybrid has the appearance of an old man, whereas the standard Hybrids look like young women and are identical.

In his Battlestar Galactica Podcast, Ronald Moore explained that the Hybrids should be considered an intermediate step between humanoid and mechanical model Cylons. They are not to be confused with the hybrid human/Cylon child Hera Agathon.

The Basestar Hybrids are played by Tiffany Lyndall-Knight. The First Hybrid is played by Campbell Lane.

Religion

Humanoid Cylons, except for the Cavil models, follow a monotheistic religion. Religious fanaticism partially motivates their genocide of humanity, and despite their origins, the Cylons believe themselves to be spiritual beings. This monotheism seems to share some of the characteristics as the Abrahamic religions: belief that God is omniscient, omnipotent, omnibenevolent, that he will one day deliver divine retribution, and that he intervenes in the mundane world.

Ronald D. Moore, the creator of the show, has said that this comes when a race becomes sentient and self-aware — questioning faith and religion and about what happens after death.

Their beliefs are separate from the Christian beliefs in that there is no heaven and hell, and they deal with issues such as consciousness, enlightenment and reincarnation.

The different models of Cylon have slightly different ways of talking about and dealing with their god, reflecting the different aspects of humanity that each Cylon model reflects. As shown in at least one case, the Number Ones in season four, the cylons do not all believe in god and can be agnostic or atheist. In contrast, Leoben Conoy (model Number 2) is fanatically religious, even compared to the other Cylon models.

Vulnerabilities

In general, Cylons seem to be physically stronger than humans. While this is obvious with respect to Centurions, the extent to which this is also true of humanoid Cylons is unclear. In the miniseries, William Adama fought in hand-to-hand combat against a number two who, despite suffering from the effects of radiation, proved to be physically stronger than Adama. At one point, the number two managed to break off a metal pipe to use as a club and lift Adama off the floor with one arm. In the episode "Flesh and Bone", another number two was able to break apart a pair of metal handcuffs while under interrogation. In the first season finale, "Kobol's Last Gleaming II", a number six engaged Kara Thrace in hand-to-hand combat and proved to be exceptionally fast, agile, and strong. Despite these demonstrations of physical strength and dexterity, humanoid Cylons are vulnerable to most of the same limitations as humans. The number two who fought Adama was beaten to death with a flashlight while the number six who fought Thrace was impaled by a piece of rebar. While humanoid Cylons may be at the peak of human physical strength, even perhaps exceeding it, they do not appear to be superhuman, and trauma which would cause severe injury or death in a human can be expected to do the same to a Cylon. In particular, and as evidenced throughout the series, Cylon skin appears just as vulnerable to breaking as human skin, with the resulting injury bleeding just as a comparable wound would in a human.

Cylons are highly susceptible to an ancient virus which can be transmitted by rodents, but which humans have developed an immunity to, lymphocytic encephalitis. This virus was carried on a beacon left by the Thirteenth Tribe at the Lion's Head Nebula millennia ago, and disrupts all organic Cylon technology including Raiders, Hybrids (which in turn disrupts Centurions), and humanoid Model Cylons. The humans speculate that the beacon was accidentally contaminated when someone sneezed. The Cylons believe that a critical symptom of this virus, a harmful bioelectric feedback, can be transmitted during a download and have so far prevented any Cylons infected from being downloaded into a resurrection ship. The only Cylon found to be immune is a Number 8 model, Sharon "Athena" Agathon, who had given birth to a half-human child.

Dr. Cottle developed a vaccine to the virus, which had infected a number of humanoid Cylons on a basestar near the Lion's Head Nebula. The RNA of the vaccine broke down in the blood stream of a Cylon humanoid model by their own immune response, forcing regular injections to keep an infected Cylon healthy. The Cylons themselves have not managed to develop an antidote or vaccine to the virus.

In addition to this, the silica pathways of humanoid Cylons are affected by certain forms of radiation, such as that surrounding Ragnar Anchorage. It is assumed but not stated that this radiation affects all types of Cylon, as the station was chosen as a refuge by Commander Adama before he learned of the existence of biomechanical models, and the radiation had deleterious effects on the Number Two model they found at Ragnar Anchorage. This also suggests that humans are not vulnerable to the effects of this radiation. In addition, plutonium is used for Baltar's Cylon Detector because its radiation affects humans and Cylons differently. The detector was dropped as a plot device early in Season 2, as the revelation of Boomer (who had been a beta test subject) as a Cylon convinced the command staff that the detector did not work. In reality, Dr. Baltar lied about Boomer's test results.
