Humanoid Cylons are the quintessential Cylon form in the Re-imagined Series. These Cylons biologically mimic human form so completely that they are nearly undetectable to current Colonial technologies.

Humanoid Cylons have the capacity to emulate many human physical acts, including sex. They also display convincingly human personalities (affection, jealousy, sadness, anger, sense of humor, religious faith, etc.) This behavior continues even when interacting with other Cylons outside of Colonial scrutiny, clearly establishing that their personalities are genuine.

The humanoid Cylons are responsible for masterminding the complete destruction of the Twelve Colonies through their use of sabotage and infiltration.

Origins

Following the end of the Cylon War (Miniseries), nothing was heard of the Cylons in 40 years.

Numbers Six, Three, and Eight

During their forty years of isolation, the Cylons developed or evolved into a humanoid form.

The creation of the humanoid Cylon is left to speculation based on series events. While the opening credits claim that the Cylons "evolved", the concept of biological evolution (in the Darwinian fashion) is impossible with mechanical beings. The "evolution" is obviously a planned architectural change from the mechanical to the biomechanical for the inherent Cylon design.

The first step in their evolution from pure machines to organic beings was known as the "Hybrid." Other hybrids were later created to control baseships (Razor). Exactly how the original Cylon, the Cylon Centurion Model 0005, a sentient robot "evolved" to the humanoid form is uncertain. Saul Tigh, a humanoid Cylon, has an apparent age that would place his birth (if he was born) well before the first Cylon War, and possibly even before the creation of the original mechanical Cylon. His military record documents his existence during the war. Number Three's conversation with Number One immediately before she was boxed indicates that the humanoid Cylons do not know who programmed them or why.

Series information shows that the humanoid Cylons existed in secret for at least two years prior to the Colonies' destruction. This information does not provide concrete evidence as to when the first models were created or how long they have been among the human population. Some of them were among the human population for at least several decades prior to the war.

Physiology and Psychology

Humanoid Cylons are visually indistinguishable from humans, down to the cellular level, but not completely at a molecular level. Dr. Gaius Baltar is able to create a detector that can distinguish Cylon from human, but rarely used the device to a positive end (Tigh Me Up, Tigh Me Down).

Each humanoid Cylon has the same face, stature, hair, eye and skin color, gender, apparent age, and other biometrics as all the others of his or her model. This point technically makes each copy a twin of itself, but there are some models that choose to make cosmetic differences. Examples include D'Anna Biers, Gina Inviere, and a Number Six model with black hair (Torn). In addition, each copy appears to start with the same basic personality, but each personality grows more distinct due to their individual experiences.

Humanoid Cylons can be programmed as 'sleeper agents', who appear to have a low-level Cylon personality that can conduct operations while placing the human sleeper personality "on-hold." "Boomer" Valerii was one such agent (Kobol's Last Gleaming, Part II). Most agent copies, particularly Numbers Five and Six, assume a human persona but are fully aware of their true nature and behave more or less as a human "spy."

The emotionally scarred Number Six copy known as "Gina Inviere".

They are susceptible to the same emotional traumas and joys that their human counterparts are, further proving that personalities are a realistic part of their psyche. A case in point is a copy of Number Six, known as Gina Inviere, who is physically and sexually assaulted repeatedly by the crew of Pegasus. These repeated assaults lead to Inviere's near-catatonic state at the time Pegasus discovers the Fleet (Pegasus).

Humanoid Cylons can dream, a process that appears to be natural to them.

Some or all Cylon female models may have the capacity to bear children seeded by human males ("33", "Flesh and Bone", "The Hand of God", "Kobol's Last Gleaming, Part II"). The Cylons tested numerous methods of sexual reproduction, yet these failed due to a known flaw in their design. The seven widely known models of Humanoid Cylons cannot reproduce with each other biologically, so in an attempt to subvert this deficiency, they try to interbreed with humans, creating hybrid offspring. "Farms" were set up across all the occupied Colonies where survivors, specifically, young fertile women of child-bearing age, were rounded up, placed under heavy sedation and turned into "baby machines" through artificial insemination. However, this methods have been unsuccessful thus far. Another drastically different approach is taken by attempting to conceive a child through a bond of love. To most of the characters it seems that Helo and Athena's love-child, Hera is the lone success story of the relatively short history of Cylon sexual reproduction (The Farm), with the hybrid nature of Galen Tyrol's child Nicholas Tyrol unknown to anyone but the four recently revealed members of the Final Five. More recently, the humanoid Cylons Saul Tigh (another of the Final Five) and Caprica-Six have conceived an unborn child.

The bodies of humanoid Cylons sometimes appear to have tremendous stamina and strength, and appear to be designed to destroy or resist commonly dangerous human diseases, although they are not immune from all contagions. In keeping with their desire to be a better human, however, the Cylons did not or could not further improve on other characteristic design flaws of the human body. Humanoid Cylons are heavily fortified to resist damage from intense radiation fields that would kill a human after short exposure (The Passage), but they are still susceptible to damage from certain types of radiation or trauma (Miniseries). Despite their resistance to certain forms of energy, humanoid Cylons, unlike the Cylon Centurion, cannot be made "bulletproof" ("Precipice", "Hero").

Cylon Religion

Main article: Cylon Religion

The Cylon follow a monotheistic religion to varying extents. Fanatical devotion to God is the central part of Number Two's character, whilst the Sixes, Threes and to a lesser extent the Eights also seem to have strong faith. The Number Ones appear to be atheistic. Fours' and Fives' views are not so well known, but they too take the "non-religious side" in the Cylon Civil War.

Cybernetic Behavior

Valerii interfaces with Galactica's computer systems.

Upon the death of its body, a humanoid Cylon's consciousness is automatically transferred into another copy of itself. This "resurrection" is limited by signal integrity and proximity to the Cylon homeworld or a Resurrection Ship (Miniseries, "Flesh and Bone", "Resurrection Ship, Part II").

It appears that all humanoid Cylons share a collective knowledge base of data from other active or deactivated humanoid Cylons, regardless of their model.

As a humanoid Cylon downloads after being killed, it is apparent that the Cylon's memories are automatically stored for future use, such as uploading them into another copy of that specific model. Once these memories are implanted they become as real to the receiving Cylon as their own original memories. This downloading of memories seems to be involuntary as Athena had no reason to do such a thing (The Hub).

The humanoid Cylons' psychology is based on what they simply refer to as "projection". Essentially an enhanced form of a self-induced and controlled hallucination, projection is how they choose to see the world around them, in any form they wish, whenever they wish. For example, if a Cylon were standing in a hallway, they could choose to see it as a forest filled with birds, trees, and sunlight. This mode of visualization is pleasing to humanoid Cylons (Torn).

Although they cannot do so remotely or wirelessly, humanoid Cylons can interface with a computer system or computer network by photo-electrical means. They can perform this through subdermal physical contact if required (Flight of the Phoenix) or, preferably, through a Cylon data-font. This might be possible through the use of bio-luminescent and photosensitive cells in their hands.

Anders's "red eye" moment.

The presence of a water-like fluid as an integral part of the basestar, the ability to interface photo-electronically through subdermal and dermal contact, and the fact that humanoid Cylon are anatomically indistinguishable from human beings, implies that the techniques used in their creation are advanced enough to incorporate cybernetic functions into their design without the use of specific internal structures other than human-like organs.

After being "stared at" by a Cylon Raider, Samuel Anders's right eye briefly flashes red, the Raider responds to this apparent IFF procedure by flying away, and a Cylon fleet attacking the Colonials retreats (He That Believeth In Me).

Known Cylon Models

There are twelve models of humanoid Cylons (Miniseries), representing twelve personality archetypes that the Cylons have witnessed in humanity. These can be divided into two separate groups, the "Significant Seven" and the "Final Five". According to show producers, the two groups are "fundamentally different."^{[citation needed]} The religion, origin, physiology and cybernetic properties of the Final Five remain largely unrevealed.

The Significant Seven have numerical designations, however the Final Five do not, leaving the number seven apparently unassigned. The models are also referred to by their "human names", even by other Cylons, although the Sixes lack a single standard name. There appears to be no significance to any of the specific numbers assigned to the different Cylons.

Significant Seven

Seven models revealed to the viewers as Cylons have also been revealed to the central Colonial characters within the first two seasons. There are many copies of each model, although the specific number of copies per model has not been specified; although a Number One known as Cavil has stated it is in the millions. The identities of these mechanized copies are determined by their model and each model is unique (Six of One).

Number One

Number One/Cavil

One of the Number One models poses as a Colonial brother named Cavil, a lay clergyman in the Fleet.

Ones do not appear to subscribe to overall theology of the Cylons, but adhere to group consensus, and often are persuasive leaders. Ones have displayed a condescending attitude toward the beliefs of the other six known Cylons at times.

In several instances, the Ones advocate dark, draconian solutions to the insurgency on New Caprica that reveal a militant zeal equaling that of Numbers Three and Five.

This Number One model in particular seems to be in something approaching a leadership role on one of the basestars, as seen in the episode "Six of One". This model assumes some authority and wields influence over the others, yet decisions are still reached through majority vote. However, this is soon overturned by the rebellion of the Cylons led by Natalie, a Number Six, and the body of this One is killed by Centurions.

Number Two

Number Two/Leoben Conoy

Number Two, better known as Leoben Conoy, is the fourth model seen by viewers (although viewers would not know until the end of the Miniseries that they had already seen the third introduced humanoid Cylon, Sharon Valerii). The Two model has shown to be mystically oriented--making references to the oneness of the universe, the illusion of time, etc.--and claims to be prescient on some level, albeit with a known propensity for intermixing truth with falsehoods. He is first discovered on Ragnar Station, claiming to be a scavenger and arms dealer (Miniseries).

The Two models also appear obsessed with matters of mating, bonding, and reproduction, as demonstrated by a particular model's fascination and obsession with Kara Thrace ("Flesh and Bone", "Lay Down Your Burdens, Part II", "Occupation", "Precipice" and "Exodus, Part II").

Two can be likened to the serpent of the Genesis tale in the Earth Christian Bible, taunting people with knowledge, then watching as the negative consequences come into devastating fruition. Copies have likely been encountered by the Caprica Resistance, as Samuel Anders recites in jest some comments made by another Number Two copy captured in the Fleet ("Flesh and Bone", "The Farm").

Number Three

Number Three/D'Anna Biers

First seen posing as a reporter from the Fleet News Service, this model is revealed to be a Cylon at the end of "Final Cut" when a second copy is shown living on Caprica. Threes seem to be the most calculating and duplicitous models shown to-date, even manipulating and deceiving other models if they feel warranted. The copy that tried to box Sharon Valerii exhibited these characteristics strongly in the episode "Downloaded".

This model's status as a Cylon is unknown to the Colonials until either shortly after the rescue of the surviving members of the Caprica Resistance or after the Cylon occupation of New Caprica (Lay Down Your Burdens, Part II).

After the Threes defy other Cylon models in their attempt to discern the identity of the five missing Cylon humanoids, the other Cylons conclude that the Three model has an inherent flaw that threatens their overall reliability. After the failure on the algae planet to gather information on the path to Earth, the Cylons have all Number Three models boxed indefinitely, until she is unboxed to ostensibly stop the rebels from fighting (Rapture). With the Resurrection Hub destroyed, she is the only Number Three copy in existence. She joins the rebels to make contact with the Final Five and eventually reaches Earth with them ("The Hub", "Revelations").

The first encountered copy of this model appeared under the alias "D'Anna Biers", and the D'Anna name is sometimes used to describe the model as a whole.

Number Four

Number Four/Simon

The Number Four model is first encountered by Kara Thrace on Cylon-occupied Caprica. Posing as a doctor under the name Simon, this Number Four is actually involved with the Cylon hybridization program. Simon resembles a tall, somewhat thin middle-aged black man who speaks in a comforting strong voice (The Farm) Unlike other models, Number Four does not seem to have many military aspects to his physical or mental configuration, and is easily overcome by a wounded Thrace. Simon may be a model based primarily on human intellectualism and logic. It is unknown if a Four model infiltrated the Fleet prior to the occupation of New Caprica. In any case, the model is now known to the general populace, many humans likely saw a Number Four model during the occupation.

Number Five

Number Five/Aaron Doral

This model attempts to sow the seeds of discontent or confusion, particularly during crucial life-threatening situations, and endeavors to undermine authority that threatens his objectives (Miniseries). Number Five models are more covert, assuming an ordinary "everyman" appearance that's blended in what may seem to be insignificant behind-the-scenes issues (such as converting Galactica into a museum). Of all the models thus far, the Number Five models are the most militant, fanatic and consistent in message and objectives to the Cylon objectives, whether he is dispassionately discussing the fate of humanity with his comrades or attempting to kill or maim Colonials in a suicide bomb attack (Litmus).

Viewers first meet a Number Five during a tour of Galactica with other Colonial citizens (possibly the press) at the start of the Miniseries, but are not sure of the Cylon's true identity until the Miniseries' conclusion.

Copies of this model have appeared under the alias "Aaron Doral".

Number Six

Number Six

This is the first humanoid Cylon model shown to viewers at the start of the Miniseries.

Stunningly beautiful, promiscuous and sensual, this model utilizes the human need and desire for sexual relations to her advantage. She tends to be very religious and monotheistic. Number Six desires to know what it is to be alive. There is something inherently enigmatic about her, more so than with the other models. Sixes have been described as "usually so hardcore", referring to their tendencies towards violence.

Sixes are the only model who appear not to have one particular "human name", copies have appeared under the aliases "Shelly Godfrey", "Gina Inviere", "Natalie", and "Caprica" (in honor of her work on Caprica towards the destruction of the Colonies). Virtual Six, whom only Gaius Baltar can see is a mainstay of the cast, and is clearly the dominant party in their "relationship".

Number Eight

Number Eight/Sharon

Number Eight is generally a saboteur designed to infiltrate Colonial military units and is likely programmed to use any Colonial munitions to cause havoc (Water). The Number Eight model is the closest witnessed humanoid Cylon model to show its abilities as a soldier. This model has shown naiveté in many matters. She is apparently not as religious as other Cylon models, but has demonstrated that she can love, and is capable of being impregnated by a human ("Six Degrees of Separation", "Kobol's Last Gleaming, Part II").

She may be "defective", as the Cylon programming within the sleeper agent known as "Boomer" on Galactica conflicts multiple times with its human personality (Water). Also, the fully aware Sharon Valerii found by Helo on Caprica switches alliances from Cylon to Colonial after falling in love with Helo and aids the Colonials for a time (several episodes, most notably "Flight of the Phoenix"). Number Eight is the third humanoid Cylon introduced during the Miniseries. However, viewers do not discover her true identity until the very end of the Miniseries when a second copy of Sharon Valerii appears at Ragnar Anchorage while retrieving an abandoned copy of Number Five.

A copy of this model has appeared under the name "Sharon "Boomer" Valerii." One copy, Sharon "Athena" Agathon, has defected from the Cylon and has joined the Colonial Fleet, generally replacing her "Boomer" counterpart as a Raptor pilot.

Final Five

Main article: Final Five

The identities of the remaining five Cylon models remained a mystery long after the revelation of the identities of the "Significant Seven".

In "Torn", Caprica-Six mentions to Gaius Baltar that the Cylons do not talk about the missing five humanoid Cylons. In the same episode, Baltar confirms that, during his time with the Cylons on occupied New Caprica and on a basestar, he only saw the first seven models. It is later revealed that the Significant Seven themselves do not know (or have repressed) the identities of these final five models, until the battle at the Ionian nebula in which the Raiders identify one of the members of the Final Five, causing a divide between the Seven.

In "Crossroads, Part II" four major characters discover they are Cylons: Galen Tyrol, Saul Tigh, Samuel Anders and Tory Foster. They were previously unaware of their nature, and this information is limited only to themselves. While shocked by their discovery, they initially agree to remain loyal to humanity until "Revelations", when D'Anna reveals the identities.

The Final Cylon model

See also: Humanoid Cylon speculation

There remains one final Cylon model to be revealed. During a Q&A session on the official Sci Fi Channel Battlestar Galactica forum, Ron Moore notes that he has already decided who the last Cylon is, and has already left clues as to who it is.

The Thirteenth Cylon

In "Sine Qua Non", Caprica-Six is discovered to be pregnant, and Saul Tigh is accused of fathering the child. If so, this would be the first completely Cylon conception.

Human/Cylon Hybrids

Conceived by Sharon and Karl Agathon, the infant Hera Agathon is the first known human/Cylon hybrid.

Gaius Baltar's internal Number Six regularly insists that Hera is actually the child of herself and Baltar, though there is no physical reason yet presented to justify that claim.

For some time Hera was hidden away from both humans and Cylons, and believed to be dead by her parents. President Laura Roslin had the baby hidden with Maya as her adoptive parent. Despite Roslin's attempts to protect the child on New Caprica, Hera is later found by the Cylons (Exodus, Part II).

After Hera's mother discovers that her daughter is alive, she uses her ability to download to transport to the Cylon ships, and manages to convince Caprica-Six to return the child to Galactica for medical treatment for a possible intestinal blockage, which the Cylon doctors, lacking pediatric knowledge, were unable to comprehend (Rapture).

A child, Kacey, is presented by a Number Two model to Kara Thrace as an hybrid offspring purportedly created with their genetic material in the episode "Occupation". The Cylons' ruse is revealed when Kacey's human mother later claims the child (Exodus, Part II).

Galen Tyrol's son with Callandra Tyrol, Nicky, is also a Cylon/human hybrid (Crossroads, Part II).

Speculated Infiltrators

Notes

• Ron D. Moore stated in an interview with TheFandom.com, "There is no original human Sharon. The idea is not that there was likely an original human model that they were copied from. The idea was that these models of Cylon were sort of developed out of their own study of us. The Cylons on some level looked at humanity and said 'You know what? There's really only 12 of you.' If these are the 12, and sort of if you look at them they each represent different archetypes of what humanity is." This established as canon that:
  • There are precisely twelve human Cylon models. The other varieties of Cylon spacecraft or fighters are not factored into this count of 12 models.
  • None of the humanoid Cylons were ever an actual human.
  • The twelve models are based on archetypes determined by the Cylons that form what they perceive were the specific kinds of human behavior and/or personality, distilled into twelve varieties.
• A Cylon Centurion cannot distinguish the differing versions of one model from another (Precipice). For example, if faced with two differing Number Eight models, Sharon "Boomer" Valerii and Sharon "Athena" Agathon, it would not be able to discriminate between them without external aid.
• While Centurions may not be able to tell the difference between different versions of the same model, other humanoid Cylons do not have this problem ("Downloaded", "Exodus, Part I", "The Eye of Jupiter", "Six of One").
• According to Cavil in "Exodus, Part I", the pain associated with each successive download is worse than the one before. The first download feels like little more than a headache, but the third feels like someone has rushed a white hot poker through the head. However, this might be a subjective feeling that varies with model and circumstances. Sharon Agathon's report in "Scar" supports Cavil, but a Number Three considers her last download to be rejuvenating (Downloaded).
• Some characters refer to humanoid Cylons as "skinjobs". This is a reference to the film Blade Runner in which Edward James Olmos has a supporting role. In the movie "skinjob" is used as an insult to replicants, which are bio-mechanical robots made to look human.
• According to Ron Moore, the Final Five Cylons, unlike the Significant Seven, "do not" have model numbers . As such, it would appear that there is no Cylon model Number Seven.
