Cylon Model Number Eight, known to the humans as Sharon Valerii, initially appears as a young officer with a bright future in the Colonial Fleet. She is initially encountered aboard the battlestar Galactica, where she is integrated into Colonial military life, serving as a Raptor pilot (callsign of "Boomer") with the rank of Lieutenant (junior grade).

But "Boomer" Valerii is a Cylon operative in hiding, a "sleeper agent." She has many copies. Other variants of the Valerii model are active on Cylon-occupied Caprica and were also aboard a Cylon basestar orbiting Kobol before its destruction. Of all the Cylon agents witnessed thus far, Sharon Valerii appears to behave with the strongest or most genuine human qualities. This may be the cause of this model's tendency to have conflicts between its latent Cylon or active human personalities, or even turn against its own kind.

The first copy of the Eight model is encountered on Galactica, where she has been serving as a Raptor pilot for two years (where she came from before this infiltration is unknown). She is a "sleeper" agent, programmed with false memories to think she is human.

Sharon Agathon

Another copy of the Eight model is used by the Cylons in a breeding experiment with Lt. Karl "Helo" Agathon on Cylon-occupied Caprica. Eventually, she falls in love with Helo, apparently defecting to the humans and turning on her fellow Cylons.

Other Copies

Number Eight copy at Delphi spaceport (Colonial Day)

• Shortly after the Cylon Attack ends, a copy in a pale blue tunic is one of four 'rebirth nurses' who greet Caprica-Six following her rebirth (this takes place at the same time as the events of the middle or end of the Miniseries, but is seen in the much later episode Downloaded).
• At the end of the Miniseries, a copy of Eight wearing a Colonial flight suit appears to be leading a group of Cylon agents who recover the PR Executive Copy of Aaron Doral from Ragnar Anchorage.
  • It is possible that this is the same individual as the Caprica copy. While, at the time the Miniseries had been filmed, there were no plans to have Tahmoh Penikett reprise the role of Helo, the ending of the Miniseries forms a link to "33", establishing that the Cylons have developed a plan for Helo's presence on Caprica.
• A copy of Eight is witnessed wearing a grey coat at the spaceport at Delphi. However, she is immediately "killed" by Helo's Eight copy (Colonial Day) after noticing and attempting to shoot Helo.
• Multiple copies of the Eight model are encountered on the basestar over Kobol. It is likely that they were dispatched to the Raptor in order to activate some latent portion of the Galactica copy's Cylon personality (Kobol's Last Gleaming, Part II).
• A copy of Eight is seen at the end of "Final Cut", also wearing a grey coat like other Sharons on Caprica, remarking in surprise that Caprica-Valerii is still alive (and that she had told the Number Five copy sitting next to her as much).
• Numerous copies of Eight are seen on Cylon occupied Caprica throughout the episode "Downloaded," the episode where it was revealed that she is the eighth in the sequence of twelve Cylon models. Various outfits are seen on them, possibly indicating different functions. Most notably, an Eight is among a group of rebirth nurses, likely the same ones that midwifed Caprica-Six, who welcome the reborn "Boomer" Valerii, who becomes hysterical after seeing and hearing this copy.

Notes

• As a matter of trivia, neither copy of Eight with extended time with the Colonials refers to her lover by his first name onscreen. "Boomer" Valerii calls Chief Tyrol by "Chief" instead of "Galen," even as she dies in his arms. Caprica-Valerii has yet to call Lt. Agathon "Karl". Ron Moore explained in his blog that no one had every really called Tyrol "Galen" before, and hearing Valerii say it would have distracted from the emotional impact of her death (RDM revealed his first name in his blog, and it has only been mentioned on screen twice, briefly at the beginning of "Resistance" and by Felix Gaeta in "Precipice"). Ron D. Moore compared it to the Seinfeld episode when Kramer's first name is revealed to be "Cosmo"; i.e. the viewers would be unused to Tyrol's previously unknown first name. As for Agathon, everybody usually just calls him "Helo" (Starbuck has only briefly called him "Karl" once or twice).
• Valerii is the male plural form of the Roman name of the family Valeria. Valerius is the singular form.
• In an interview for thefandom.com Ron D. Moore stated that "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."

There is some speculation as to whether Eight's ability to form close bonds with humans is considered an asset or a liability (or a little of both) by the Cylon majority. It would be interesting to see whether the four models created after Number Eight act more or less "human" than she.
