List of minor characters in Battlestar Galactica (2004 TV series)

This is a list of fictional characters appearing in the reimagined Battlestar Galactica fictional universe.

Adama, Ens. Zak

 * Played by: Tobias Mehler, Clarke Hudson
 * First appearance: "Miniseries"

Ensign Zak Adama was William Adama's son, Lee's brother, and the fiance of his flight instructor, Kara Thrace. His grandparents and other relations are later introduced in Caprica. He was pressured into joining the military by his father, despite Lee's insistence that Zak was ill-suited to be a pilot.

Zak introduces Lee to Kara during a dinner at the latter's home on Caprica. Lacking the other two's tolerance for alcohol, he is the first to pass out after dinner. While unconscious, he is nearly cuckolded by his fiancée and brother until the amorous pair change their minds and Lee departs.

As did Lee, Kara recognizes that Zak lacks sufficient aptitude for military aviation, but nevertheless passes him on his final flight exam because of their romantic involvement. He is soon killed in a Viper crash. Kara meets Commander William Adama at Zak's funeral. Thereafter, she wears Zak's ring on her thumb.

Allison, Lt. Noel "Narcho"

 * Played by: Sebastian Spence
 * First appearance: "Pegasus"

Lieutenant Noel "Narcho" Allison is a pilot originally seen on the Battlestar Pegasus. He is stubborn and full of bravado, scoffing at plans to use the Blackbird and bragging about his Cylon kill count, (which at the time was 48). After Pegasus is destroyed, he becomes part of the Galactica crew. He is briefly seen as one of the Viper pilots guiding the fleet in "The Passage", including his name on the duty roster of still living pilots, and again in "A Day in the Life", commenting on the number of days since the fleet has last seen the Cylons. He again appears, albeit briefly, in a pilot meeting sitting in attendance, in "The Son Also Rises". He is among the mutineers in "The Oath", and is ordered by Gaeta to destroy the Raptor carrying Roslin and Baltar to the Cylon baseship. Thanks to Hotdog's reluctance, Allison fails and Roslin and Baltar escape to the baseship. He is ordered to lead the firing squad to kill Adama and though he is reluctant, he accepts. Before the execution can be carried out, crewmembers loyal to Adama free him and Allison is forced at gunpoint by Colonel Tigh to tell Gaeta by telephone that he will carry out the execution, but seems almost relieved that he won't have to carry out the order. Adama successfully enlists the help of the marines in retaking the ship, but Allison refuses to help saying that while he has always respected Adama, he won't work for someone that won't fight the Cylons so Adama has him tied up. He is presumably later jailed with the rest of the mutineers and it is unclear if he accepted the offer of a pardon in exchange for fighting in the final battle and if he did, whether or not he survived it.

Belzen, Col. Jurgen

 * Played by: Steve Bacic
 * First appearance: "Battlestar Galactica: Razor"

Colonel Jurgen Belzen was the executive officer aboard Battlestar Pegasus and close friend to Admiral Helena Cain prior to the Destruction of the Colonies. He invited Cain to visit with him and his family on Gemenon. Although a proponent in Cain's plan to wage guerrilla warfare against the Cylons after the attack, he was a moral man who had reservations against recklessly sacrificing any more lives for this goal. During an attack on a supposedly defenseless Cylon relay station - revealed to be a heavily defended staging ground and part of a Cylon trap - he refused Cain's order to carry out the attack in spite of overwhelming odds. Cain demanded his sidearm and summarily executed him, then turned to Colonel Jack Fisk, one of several officers clearly shocked by her actions, named him XO in Belzen's place and ordered him to carry out the attack.

Cain, Adm. Helena

 * Played by: Michelle Forbes
 * First appearance: "Pegasus"
 * Final appearance: "Battlestar Galactica: Razor"

Rear Admiral Helena Cain is commander of the Battlestar Pegasus, a battlestar that Galactica encounters. She lost her family in a Cylon attack on Tauron on the last day of the first Cylon war. Ruthless and Machiavellian, she is a force to be reckoned with. While the Galactica encounted a civilian fleet and in turn offered it its protection (under the insistence of President Roslin), Pegasus, under the orders of Cain pillages the civilian fleet it encounters and murders the people who resist. Cain justifies these actions on they premise that they are fighting a war, but fails to realize that the people she essentially commits genocide against are the very people she is sworn to protect. She seems to have delusions of grandeur about her authority as evidenced by her ordering of an assassination attempt on Adama, before backing down. She briefly takes Starbuck under her wing. She is later killed by Gina, the Cylon prisoner (and former lover) she had tortured.

Clellan, Lt.JG Tucker "Duck"
Lieutenant-Jr. Grade Tucker "Duck" Clellan is a pilot aboard Galactica. He often provides snide remarks and hassles rookie pilots. On New Caprica, his wife, Nora, is killed by Centurions. Because of this, he elects to become a suicide bomber, and dies while blowing up a New Caprican Police graduation ceremony.
 * Played by: Christian Tessier
 * First appearance: "Flight of the Phoenix"

Costanza, Lt.JG Brendan "Hot Dog"

 * Played by: Bodie Olmos
 * First appearance: "Act of Contrition"

Lieutenant Junior Grade Brendan "Hot Dog" Costanza is a cocky pilot who is often seen alongside Kat. He often suffers massive setbacks, such as being punched out quite easily by Starbuck during the "dance", or losing the Adriatic; however, he did lead the Viper squadron during the fight for New Caprica and against the Cylon colony. In the 4th season episode "A Disquiet Follows My Soul", Hot Dog learns that he is the biological father of Nicholas Tyrol.

Cottle, Maj. Sherman "Doc"

 * Played by: Donnelly Rhodes
 * First appearance: "Act of Contrition"

Major Sherman Cottle, MD is a gruff, cynical physician who is nonetheless honorable and dedicated to his profession. He treats Roslin for her breast cancer, and delivers Sharon Agathon's baby, Hera (while being ordered to fake her death). 

He is always addressed as "Doc," never by his given name or rank. Cottle has a deep gravelly voice and very authoritarian manner. He also has a very involved smoking addiction. Doc Cottle is almost never seen without a cigarette in his mouth or hand. Cottle will perform abortions if requested and objected when the practice was outlawed in the Fleet to prop up birth rates.

Cottle is shown to actually be a very caring person as shown when a tearful Roslin thanks him and he gets choked up before Roslin tells him to grumble, smoke a cigarette and save his reputation, indicating he hides how much he cares with his attitude. He is one of the first to volunteer for the mission to rescue Hera Agathon, but Adama sends him back saying the Fleet can't afford to lose a doctor. When Adama sends him back, he calls him by his first name, finally revealing it: Sherman.

Edmondson, Lt. Margaret "Racetrack"

 * Played by: Leah Cairns
 * First appearance: "Kobol's Last Gleaming, Part 2"
 * Final appearance: "Daybreak, Part. II"

Lieutenant Margaret "Racetrack" Edmondson is a Raptor pilot and ECO, brought in as Crashdown's replacement. She is cynical and emotional. Before the return to New Caprica, she leads the Galactica flight wing in prayer. Although she initially distrusts Sharon Agathon, she later forms a friendship with her but quickly abandons this friendship when she joins the mutineers in "The Oath". She is killed during the attack on the Cylon Colony ship in "Daybreak, Part. II". In an odd twist of fate, her lifeless hand touches down on her raptor's firing button and fires a spread of nuclear missiles that destroy the Cylon Colony, fulfilling her wish to take as many Cylons with her as she can upon her death.

Figurski, Crewman Anthony

 * Played by: Don Thompson
 * First appearance: "Flight of the Phoenix"

Anthony Figurski is a petty officer serving as a hangar bay deckhand aboard Galactica. He is a middle-aged man, described as somewhat "slow" yet a reliable crewman by his shipmates.

 * First appearance: "Act of Contrition"
 * Final appearance: "Litmus"

Sergeant Hadrian is Galactica ' s tough-as-nails Master-at-Arms.

Hoshi, Lt. Louis

 * Played by: Brad Dryborough
 * First appearance: "Pegasus"

Lieutenant Louis Hoshi is an officer, originally serving in the CIC aboard the Battlestar Pegasus. His duties appeared to be similar to those of Lieutenant Felix Gaeta aboard Galactica. After the destruction of Pegasus above New Caprica, Hoshi is assigned to Galactica’s CIC. He appears to serve as communications officer, relaying various messages and communications to Admiral Adama ("The Eye of Jupiter"), somewhat taking the duties previously assigned to Specialist Anastasia Dualla prior to her commission.

In The Face of the Enemy webisodes, he is shown as being in a romantic relationship with Felix Gaeta. He takes over Dualla's position as com officer following her suicide, but does not support Gaeta's mutiny a few days later.

In "Daybreak, Part. II", the final episode of the series, Admiral Adama brevets Hoshi to the rank of Rear Admiral (fulfilling Gaeta's prediction of him having "a bright future"). As the senior officer ordered to remain behind with the human fleet, Hoshi assumes command of the Cylon Basestar and the defense of the colonies under acting president Romo Lampkin, while Admiral Adama, President Roslin, and Vice President Adama take Galactica on a mission to attack the Cylon Colony. After the fleet settles on the new Earth, Hoshi returns the Admiral rank pins to Adama, commenting about their excessively heavy "weight". He was commenting on the heavy responsibilities of high rank.

In the episode "Downloaded" she helps Cottle deliver Sharon Agathon's baby Hera. Ishay slips the fact that Tyrol is not the father of his son Nicholas in the episode "A Disquiet Follows My Soul". While talking to Felix Gaeta while he waits for treatment for his amputated leg, she agrees with his hostility to Cylons. In "No Exit", she tells Starbuck that Sam Anders's brain is not functioning after his surgery. Ishay volunteers for the final mission in "Daybreak, Pt.1" and supervises Galactica's infirmary during the battle. She is last seen dealing with the many injuries among the crew, and it is assumed she survived to settle on Earth.

 * Played by: Luciana Carro
 * First appearance: "Act of Contrition"

She becomes Galactica&#x27;s CAG when Starbuck leaves the fleet and settles on New Caprica. After the Battlestar Pegasus is destroyed during the exodus from New Caprica, Apollo returns to the Galactica and replaces Kat as the CAG (although Kat appears to keep her rank as Captain).

During a difficult passage through a radiation heavy sector of space, it is revealed that Kat's identity is false and that she was in fact a former drug runner who may have allowed the Cylons to infiltrate Caprica during one or more of her drug runs from the Outer Colonies. She sacrifices her life, absorbing a lethal dose of radiation, to save one of the civilian ships. As she lies dying in med-lab, Adama promotes her to CAG again. After she dies, Starbuck pins her photo onto the memorial wall.

For this he is stripped of his rank and position and confined to Galactica's brig. In "The Oath", he leads the fire team of rebel marines trying to prevent President Roslin and Gaius Baltar's escape.

It is learned that Laird was a civilian aerospace engineer who was aboard the passenger ship Scylla and forcibly conscripted by Cain to serve aboard her ship under threat of his family's summary execution. Laird assumes Tyrol's responsibilities as senior deck chief when Tyrol (possibly intentionally) gets himself reduced in rank to specialist after discovering his Cylon nature and mourning Cally's death.

He helps Cally escape execution and is the only survivor of his group and escapes. During the exodus, Vice President Zarek orders him to escort former (and future) President Roslin to safety. Roslin insists upon leaving aboard the abandoned Colonial One, and Lyman escapes the planet with her on board that ship.

He had been piloting a Stealthstar. The Cylons let him go after three years in captivity aboard a Basestar hoping that he would murder Adama for vengeance. The plan was a partial success, as Bulldog did attack Adama, but after Tigh calmed down Bulldog by reminding him of the harsh realities of life in the military, Bulldog ceased his attack. He was later given a uniform by Adama, and left for another ship. Whether Novacek survived the journey of the Colonial fleet remains unknown.

Reinstalled into the presidency, Laura Roslin pardons all remaining suspected collaborators with the sole exception of former President Gaius Baltar, and disbands the Circle. Seelix wished to become a Viper pilot, but was denied her wings because the CAG deemed her flight-deck position too important. Later Seelix was granted flight status and promoted to the rank of ensign with the call sign "Hardball". In episode "Faith", Seelix accuses Starbuck of being a Cylon.

Toward the end of the season three, Seelix begins to have romantic feelings for Samuel Anders and had hoped to start a relationship with him during Starbuck's absence. In the 4th season episode "The Oath", Seelix joins in Gaeta's mutiny aboard Galactica. She helps capture Anders whereupon she states her disgust for having fallen for a Cylon. She is not seen in subsequent episodes, but Ronald D. Moore stated that all of the mutineers were locked up aboard the prison ship. It is not known if Seelix accepted the amnesty offered in the episode "Daybreak, Part 1".

Shaw, Maj. Kendra

 * Played by: Stephanie Chaves-Jacobsen
 * Appearance: "Battlestar Galactica: Razor"; "Daybreak" Part 1

As a lieutenant, Shaw transfers to Battlestar Pegasus while the ship is undergoing an overhaul, becoming the aide to, and protégé of, Rear Admiral Helena Cain. During the holocaust, she recognises a humanoid member of the Cylon boarding party as a copy of Cain's lover, Gina Inviere (a Number Six), and thus saves the ship from Gina's sabotage. Under Cain's tutelage, Shaw becomes a dedicated officer and an extension of Cain's will. She actively participates in an incident aboard a small civilian fleet discovered by Pegasus, executing the families of unwilling draftees press-ganged by Cain. This earns her promotion to Captain and recognition as a "Razor" - the highest compliment from Cain. (Razor)

After Cain's death at the hands of the escaped Gina, Shaw's career suffers under Commanders Fisk and Garner. Garner subsequently demoted her and assigned her to kitchen duty for insubordination. (Razor)

She is selected by newly-promoted Commander Lee Adama to serve as Executive Officer with the rank of Major. Adama wanted an officer to "hold the torch" and demonstrate his devotion to maintaining Cain's legacy. (Razor)

Shaw is killed in the line of duty during a deadly rescue mission, when she stays behind aboard an old Cylon basestar to manually activate a nuclear bomb. She receives posthumous commendation from Adama's father, Rear Admiral William Adama.

When Baltar departs New Caprica with the Cylons, Zarek becomes acting President and tacitly authorizes the actions of the star chamber court known as "The Circle." Once the colonists escape New Caprica, Zarek cedes his presidency to Laura Roslin, who in turn nominates him for Vice President. He leads a coup against Roslin while Felix Gaeta leads a mutiny against Adama. He has the Quorum of Twelve murdered when they don't support him as President following the fleeing of Roslin to a Rebel Cylon Baseship.

When Helo learns of this he begins an investigation in the recent death of a Sagittaron youth named Willie King, but Robert's close friendships with Colonel Tigh and Dr. Cottle hamper Helo's attempt at finding the truth.

Thrace, Dreilide

 * Played by: Roark Critchlow
 * First appearance: "Deadlock"

Dreilide Thrace is a piano player and the father of Kara Thrace. He left the family when she was a child, and appears to her in "Deadlock" and "Someone to Watch Over Me" as a vision in the Galactica ' s hangar bay tavern. Some have speculated that he is, in fact, a Number Seven (Daniel series) Cylon, although Ron Moore has explicitly denied this.

Before abandoning the family, Dreilide teaches young Kara a melody ("All Along the Watchtower") to play on the piano, which she remembers years later during her vision of him in the tavern. She discovers that the notes line up perfectly with drawing of colorful stars which Hera Agathon recently gave her. The song is instantly recognised by the Final Five Cylons as having been written by Kara's husband, Sam Anders during the Five's previous life on Old Earth centuries earlier. In an attempt to communicate with the brain-injured Sam, Kara converts the notes into numerical designations, to no avail. When ordered by Admiral Adama to make an emergency FTL jump away from the Cylon Colony without any coordinates, Kara enters the notes' numerical designations into Galactica’s FTL drive, and thereby takes the ship to a point above the Moon, headed toward Earth, thus saving humanity.

Tyrol, Nicholas

 * First appearance: "Battlestar Galactica: The Resistance Webseries", "Occupation"

Nicholas Tyrol is the biological son of Cally Tyrol (née Henderson) and Brendan "Hot Dog" Costanza, and the nominal son of Cally and Galen Tyrol. Nicky was born on New Caprica where his parents had become labor organizers after their release from active duty; Nicky is one of the only humans native to New Caprica. Originally, Galen believed himself to be the father; when Galen (by this time, having returned to active duty as a Senior Chief Petty Officer) was revealed to be a Cylon, Nicky was likewise assumed to be a Cylon-Human hybrid and, after Hera Agathon, only the second to be born. In "A Disquiet Follows My Soul", it is revealed that Cally had been involved in simultaneous relationships with both Galen Tyrol and Brendan Costanza prior to her marriage to Tyrol, and that Constanza was Nicky's real father. The truth had been known only to Cally, Doctor Cottle, and his medical staff.

Nash, Commander

 * Appearances: none

Commander Nash was named as the first commanding officer of the Galactica.

Nash originated the ship's strict policy against interconnecting computers and wireless communications, which all succeeding Galactica commanders have upheld.

Pythia

 * Appearances: none

Pythia is an ancient Oracle that is frequently referenced in the historical texts, legends, and religious documents of Kobol's émigrés and Colonials. The scrolls of Pythia document the exile and rebirth of mankind 3,600 years before the cylon attack on the twelve colonies.

Pythia is named after Pythia, an ancient Greek priestess who served the Oracle of Apollo at Delphi.

Number One (John Cavil)

 * Played by: Dean Stockwell
 * First appearance: "Lay Down Your Burdens, Part 1"


 * Cavil is a Cylon infiltrator who first appears to the fleet as a priest using the name Brother Cavil. However, once exposed, Cavil reveals that he is an atheist. He shows an extreme distaste for humans, and often advocates violence against them.

Number Two (Leoben Conoy)

 * Played by: Callum Keith Rennie
 * First appearance: "Miniseries"


 * Leoben Conoy is a Cylon infiltrator who first appears to be a common criminal. This model is an expert at manipulation. He is also devoutly religious, and often has visions. One copy has an obsession with Starbuck.

Number Three (D'Anna Biers)
Played by: Lucy Lawless
 * First appearance: "Final Cut"
 * Final appearance: "Sometimes a Great Notion"


 * Number Three is a Cylon infiltrator who first appears to be a fleet reporter named D'Anna Biers. After she rejoins the Cylon fleet, she enters into a sexual relationship with both Caprica Six and Gaius Baltar, and experiments with the downloading process by repeatedly "killing" herself (which the other Cylons find blasphemous). When the other Cylons feel threatened by her, they "box" all of the Threes (putting their memories in cold storage indefinitely).

Number Four (Simon)

 * Played by: Rick Worthy
 * First appearance: "The Farm"


 * Simon is a Cylon who first appears to be a Caprican doctor.

Number Five (Aaron Doral)

 * Played by: Matthew Bennett
 * First appearance: "Miniseries"


 * Number Five is a Cylon infiltrator who first appears to the fleet as a Public Relations manager. He claimed that he was from Oasis, a small hamlet outside Caprica City and that he had attended the Kobol Colleges on Gemenon. He is often vicious and prone to violence and threats thereof.

Number Six

 * Played by: Tricia Helfer
 * First appearance: "Miniseries"


 * Number Six is a Cylon infiltrator in the form of a blonde female. The Number Six in several guises has brought about many key moments.  See the main article on this type for more details.  This model is unique in that different copies use different first names (i.e., Gina, Natalie, Shelly, etc.).  All the others have a set name that is used to refer to all the copies in that model.

Number Seven (Daniel)

 * Appearances: none


 * Number Seven was to have been a male humanoid Cylon, one of the eight models developed by the Final Five to end the First Cylon War. "Daniel" was gentle and artistic, and a favorite of Ellen Tigh.  The John Cavil model became jealous of this attention and sabotaged the genetic code and amniotic fluid used to prepare the Daniel copies, and as a result there were no "Number Seven" copies - though the existence or whereabouts of the original is unknown.

Number Eight (Sharon Valerii)

 * Played by: Grace Park
 * First appearance: "Miniseries"


 * Number Eight is a Cylon infiltrator. The Eight model is generally manipulative and fickle.  This is the only one of the seven active models which have experienced a split in ranks.  The copy known as Boomer dissented from the other Number Eights and joined Cavil's faction in the Cylon civil war when the other Eights joined the Twos, Three(s), and Sixes.  Additionally, the Sharon copy known as "Athena" is the only mass-produced Cylon (not "Final Five") to have taken a commission in the Colonial military.

Hybrid

 * Played by: Tiffany Lyndall-Knight
 * First appearance: "Torn"


 * The Hybrid is a Cylon that is partly female humanoid but is permanently fused to a basestar, which she controls. The Hybrids speak in constant, poetic gibberish, which not even the other Cylons can decipher. Some models see this as a form of madness caused by the mental stress of controlling all of the baseship's functions, while other models, particularly Leoben, see the Hybrids as oracles speaking the word of God. The Hybrid does not appear to be ranked as one of the twelve "human" models, and despite showing sentience and disapproval of decisions made by the seven "skin job" Cylons, the Hybrid does not "get a vote" in matters of importance.

Prototype Hybrid

 * Played by: Campbell Lane
 * Only appearance: "Battlestar Galactica: Razor"


 * The "original" Hybrid was a Cylon that is partly male humanoid, was developed in a planet-side lab and then fused into an old-style Basestar. The prototype Hybrid is clairvoyant, and seemingly omniscient, and unlike the later model, speaks cogently. The old-style Cylon Centurions protect it vigorously from humans and later model Cylons alike. It is destroyed by Kendra Shaw with a manually armed nuclear bomb, along with its Basestar.

Scar

 * Played by: N/A
 * Only appearance: "Scar"

Scar is the Colonial nickname for a Cylon Raider ace who is proficient in shooting down Viper pilots, especially nuggets. Scar was given the nickname by Colonial pilots because of a deep gash on the side of the cockpit and was responsible for ambushing and destroying multiple viper patrols using highly effective hit-and-run and divide-and-conquer tactics, primarily during fleet operations in an asteroid field involving the mining ship Majahual. Scar is destroyed by Kat.

Agathon, Hera
Hera is the human/cylon hybrid child of Helo and Sharon Agathon. Her blood is used to "cure" Roslin's cancer. Roslin, not trusting Sharon Agathon with the child, but also not wanting to kill her, decides to fake Hera's death, and gives the child to Maya, the mother of a stillborn child. After Maya's death on New Caprica, Hera is taken aboard a baseship by the Cylons. During the stand-off between the Cylons and the Colonials over the Eye of Jupiter, Helo kills Sharon at her request so she can download into a ship in the Cylon fleet. She then rescues Hera, with the help of Caprica Six, and returns to the Galactica. Later in the series, Sharon Valerii (Boomer) returns to Galactica, abducts Hera, and takes her back to Cavil aboard the Cylon Colony Station. Galactica ' s response is to mount an all-volunteer rescue mission, with considerable help from rebel Cylons, in which Hera is rescued and the Cylons' 'Loyalist' faction is destroyed. Hera then settles with her parents (and the other Colonial and rebel Cylon survivors) on a previously unknown planet that Admiral Adama christens "Earth". 150,000 years later, Hera is identified as having been Mitochondrial Eve.
