Tory Foster is a fictional character from the 2004 TV series Battlestar Galactica, portrayed by Rekha Sharma. Tory, like the other members of the Final Five, was originally from a planet called Earth. This Earth had been colonized by the 13th Tribe (composed of Cylons from the planet Kobol) roughly 4,000 years before the events of the series (c.152,000 BC as revealed by the final episode). Tory and Galen Tyrol were in a relationship in their past lives - they lived together and planned to get married. Tory and the other members of the group that would later be known as the Final Five were working to recreate the resurrection process their Cylon ancestors used to employ on Kobol, a process that had fallen out of favor on Earth due to procreation. They had some advance knowledge of the impending destruction due to warnings from people no one else could see. The messenger that appeared to Tory looked like a man. When Earth was destroyed roughly 2,000 years ago the Final Five arranged to have themselves resurrected aboard a sub-light ship orbiting earth. They then left to find the Twelve Colonies and warn them about treating their artificial life with respect or face the same doom that

Aaron Doral (Number Five) is a fictional character from the reimagined Battlestar Galactica series. Doral is a humanoid Cylon (designated model Number Five) who first appeared as a civilian public relations specialist aboard Galactica just prior to the Cylon attack on the Colonies. Through conversation with the Cylon agent Number Six, Dr. Gaius Baltar claims Doral is a Cylon spy and has him thrown in the brig. Gaius does so to protect himself and justify the finding of a Cylon device he has noticed; Doral actually being a spy is mere coincidence. Doral emphatically denies being a Cylon. However, not willing to take a chance, Doral is abandoned by Commander Adama on the Ragnar Anchorage weapons depot. At the time of abandonment, Doral exclaims his innocence, and claims to be from Oasis, outside Caprica City, and having been on Kobol College on Gemenon. The audience is shown that Baltar was correct in assuming Doral a Cylon, four copies of Doral, along with Number Six, Leoben Conoy, and Sharon come to his rescue. (In the novelization, Doral is a sleeper agent - he does not know he is a Cylon until the others come for him at Ragnar Anchorage.) Doral appears again on Cylon-occupied

Number Eight is a female humanoid Cylon model on the television series Battlestar Galactica, a reimagining of the classic show of the same name. She is portrayed by Grace Park. Two prominent Number Eight copies serving as Galactica pilots are Sharon Valerii and Sharon Agathon, using the call signs "Boomer" and "Athena", respectively. Cylon models Six and Eight are the most common in the series. Many Number Eight copies have been seen in various roles, including leadership positions; two are featured as central characters — Boomer and Athena. Lieutenant Junior Grade Sharon "Boomer" Valerii is a Cylon sleeper agent programmed to believe she is human. For example, she has been implanted with false memories of being raised on Troy by her parents Katherine and Abraham Valerii, who supposedly died in an accident killing all the members on the mining colony. Whether or not Katherine and Abraham actually existed is unknown. In the time before the mini-series, Boomer and Galen Tyrol are romantically involved, although their relationship is against military protocol (she is an officer, he's enlisted). Due to her programming, she performs a number of sabotage actions (including bombing the

John Cavil (Number One) is a fictional character and the main antagonist from the re-imagined Battlestar Galactica television series. He is portrayed by Dean Stockwell. In the fourth season episode "Six of One", Cavil's model number was revealed as Number One. John Cavil, aka Number One, is a humanoid Cylon model that appears as a highly rational, eccentric man in his late-sixties. Cavils have a heavy sarcastic demeanor and a sense of humor. They take neither religion nor death seriously and are the only atheist Cylon model. A Cavil is first seen aboard the Galactica assuming the role of a priest, offering spiritual guidance, and going by the name "Brother Cavil". One of the unique characteristics of the Cavils is the sadistic, cruel and Machiavellian streak in their personalities which goes above and beyond any anti-human sentiments the other Cylon models might share. Cavils openly mock their fellow Cylons every time they attempt contact with humans, even when it is absolutely necessary. Viewing death as a nuisance, Cavils, however, are extremely displeased with pain (placing the blame on the Final Five). This view fuels the idea that Cavils wanted death to the humans to be as

Ellen Tigh is a fictional character from the re-imagined Battlestar Galactica series. She is played by the actress Kate Vernon. Ellen Tigh is the wife of Colonel Saul Tigh. At the beginning of the series, he believes she has been killed during the Cylon attack of the Colonies while he was on Galactica. In the original miniseries, a picture of her (portrayed by the wife of series producer David Eick rather than Kate Vernon) is seen being burned by Saul, but apart from this, she does not appear until midway through the first season in the episode "Tigh Me Up, Tigh Me Down". Though they try to reconcile after their reunion, her previous infidelity strained their relationship. Ellen Tigh claims to have been rescued by an unknown hero and brought on the last flight off of Picon after she was knocked unconscious when Cylons attacked the airport. In the weeks after the exodus of the refugee fleet, she is on board the Rising Star, but until a week before her reunion with her husband, the crew do not remember seeing or administering medical care to her. Thus, William Adama has her blood tested by Gaius Baltar, who tells Adama and Laura Roslin she is human, but in a conversation with Six, he

Saul Tigh is a fictional character on Battlestar Galactica played by Michael Hogan. The character was named Paul Tigh in early scripts, and was renamed due to legal issues, according to producer Ronald D. Moore. He is one of the main characters of the show. Saul Tigh is a line officer assigned as executive officer on the Galactica. At the opening of the series, he believes himself to be an ex-Colonial Viper pilot, the son of another military pilot and the grandson of a Presidential military advisor, and to be around 70 years old. Memorabilia in his quarters suggest that he flew with a squadron named "Vigilantes". It is revealed during season four of the show Tigh's early memories are artificial, implanted by Brother Cavil when he killed and temporarily boxed Saul and his fellow Final Five Cylons. It is unclear if these memories were fabricated or taken from a human by Cavil. Tigh is actually a survivor of the ill fated 13th tribe, a tribe made entirely of Humanoid Cylons. He is approximately 2000 years old, with his last body having been operational since the first cylon war - any memories prior to that time are artificial. Tigh and the rest of the Final Five worked at the same

Leoben Conoy (Number Two) is a fictional character portrayed by Callum Keith Rennie appearing in the reimagined Battlestar Galactica series. Leoben is a humanoid Cylon agent who portrays himself as possessing philosophical and religious enlightenment. Meanwhile he delights in playing mind games by engaging in disorienting and poetic discourse that entwines truth and lies. The Number Two series model seems to be one of the physically strongest type among the humanoid cylons, demonstrating superhuman feats such as snapping handcuffs and tossing people around like ragdolls. Leoben expresses what can be judged a pantheistic view of God as inherent in all beings, telling Starbuck, "We're all God." In the fourth season episode "Six of One", Conoy's model number was revealed as Number Two. Leoben Conoy is first encountered in the miniseries by Commander Adama hiding in the Ragnar Anchorage supply depot posing as an arms dealer scrounging for weapons and supplies. Apparently to avoid arrest, Leoben offers to help Adama's supply team gather cannon shells for Galactica's defensive guns. After an explosive device accidentally detonates, Adama is trapped with Leoben and separated from the rest

Samuel T. Anders (callsign "Longshot") is a fictional character from the re-imagined Battlestar Galactica television series, played by Michael Trucco. He first appeared as a recurring character in the second season episode "Resistance", but assumed a pivotal role in the series by the end. Although not revealed until the final season of the show, Anders is approximately two thousand years old, and was born as a member of the ill-fated Thirteenth Tribe, a group consisting entirely of Cylons who left Kobol and settled on the first Earth. Along with fellow Cylons Saul Tigh, Ellen Tigh, Galen Tyrol and Tory Foster, Anders worked as part of a research group on Resurrection technology. They were warned about a coming disaster by people no one else could see. The messenger that appeared to Anders looked like a woman. When their Earth was destroyed, the five Cylons were resurrected on a subluminal ship in orbit, and traveled to the Twelve Colonies at slower-than-FTL velocities, stopping at the temple of the five on algea planet and arriving at the time of the First Cylon War. Seeking to end the conflict, the five Earth Cylons presented the Colonial Cylon forces with a deal — if the warring

Galen Tyrol (commonly referred to as The Chief) is a character on the television series Battlestar Galactica. Tyrol is responsible for the maintenance of the Vipers and Raptors aboard Battlestar Galactica. After the events of the miniseries, he was the ship's highest-ranking non-commissioned officer at rank of Senior Chief Petty Officer. Galen Tyrol is played by Aaron Douglas, who originally auditioned for the role of Lee Adama before that role went to English actor Jamie Bamber. At the start of the series, Tyrol is romantically involved with Lieutenant Sharon "Boomer" Valerii aboard Galactica, who is, unbeknownst to either Tyrol or herself, a Cylon. Once Sharon's true nature is revealed when she attempts to assassinate then-Commander Adama, Tyrol is accused of being a Cylon and is thrown into the brig with Sharon. He claims he hates her and orders her to keep her distance, but when Sharon is shot and killed by Cally, he mourns her and reveals his true affection for her. Tyrol is "proven" not to be a Cylon - for the time being - and resumes his job. Discovering the existence of Caprica-Valerii (who is pregnant and in love with Helo) confuses him, especially with Galactica-Valerii's

Simon O'Neill (Number Four), is a fictional character, a Cylon from the reimagined Battlestar Galactica series. He first appears in The Farm (August 2005), an episode written by Carla Robinson and directed by Rod Hardy. Like the Cavils and Number Threes, and in contrast to Leobens, Dorals, Number Sixes, and Number Eights, Simons appear to be relatively uncommon and never appear in large groups. He has a more prominent role in the movie The Plan. Simon first appears posing as a human physician treating Kara Thrace (Starbuck) for ballistic trauma in what was supposedly a hospital on Caprica. In reality, he was also performing invasive medical 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. This copy is then gunned down by resistance fighters who rescue her. At least one other copy is seen on Cylon-occupied Caprica. It is later revealed that a Simon was the Caprica Buccaneers' team doctor and worked against the resistance by contaminating radiation meds and giving too much morpha. This copy was eliminated after Samuel Anders

Number Six is a family of fictional characters from the reimagined science fiction television series, Battlestar Galactica. She is portrayed by Canadian actress and model Tricia Helfer. Of the twelve known Cylon models, she is the sixth of the "Significant Seven". Like the others of the "Significant Seven", there are several versions of her, including Caprica-Six, Shelly Godfrey, Gina Inviere, Natalie Faust, Lida and Sonja. She is the only model that does not use one particular human alias for all copies. The character was named after Number Six, Patrick McGoohan's character from the show The Prisoner. Six is a seductive, statuesque Cylon infiltrator. She was the first example shown of a new generation of Cylons capable of adapting to human form and emotions. Little else is known of her earlier years. She can, like other Cylons, retain memories which can be downloaded into another body if the original body is killed. Like her counterparts, her body was designed to mimic the human body at the cellular level, making her almost undetectable to testing procedures, and there are many copies of her in existence. Sixes and Eights are the Humanoid Cylon models shown most frequently. Sixes

D'Anna Biers (Number Three) is a fictional character from the re-imagined Battlestar Galactica television series, played by Lucy Lawless. Three first appeared in the episode "Final Cut" as D'Anna Biers, a reporter for the Fleet News Service. In this episode, she is given full access to Galactica by Commander Adama to film a documentary about the military. During filming, D'Anna comes across the Cylon prisoner Sharon "Athena" Agathon and discovers she is pregnant when Dr. Cottle rushes to save her baby from miscarriage. D'Anna is ordered to remove the evidence by Adama on the grounds it could jeopardize fleet security. The episode concludes with a group of Cylons watching the documentary as well as the removed footage—it is in this scene that D'Anna's identity as a Cylon is first revealed. In the episode "Downloaded", D'Anna debriefs newly resurrected Caprica Six and Sharon "Boomer" Valerii and helps them to integrate back into Cylon society. When the two begin to show sympathy towards the humans, D'Anna reacts with disgust. Ultimately she is killed by Caprica Six to protect Anders, a resistance fighter. After D'Anna has resurrected (offscreen), she claims this to be the first act
