Main Human Characters

     Commander Adama 

Commander William 'Bill' Adama (callsign: Husker)

https://static.tvtropes.org/pmwiki/pub/images/TropeAdama_3597.jpg
"It's not enough to survive. One must be worthy of survival."

An almost-retired Commander who was assigned to Galactica in the twilight of his career to oversee her decommissioning. As a veteran of the first Cylon war, Bill Adama is actually one of the better choices for command in the second war, not to mention a Cool Old Guy.

  • Abusive Parents: "A Day in the Life" shows he believes he was this to Lee and Zak of the neglectful kind, believing his duties and struggles with showing emotion was harmful to them, and that his wife Caroline’s constant harangue of him was justified, to the point of divorcing her and letting her take custody under the belief she would provide a more stable home life for them. When he admits this to Lee, Lee reveals that Caroline was alcoholic and abusive both physically and mentally, and notes she probably never cared about Bill or (implicitly) her children at all.
  • Adaptational Jerkass: The infallible Adama of the original series Bill is not: he can be very blunt at his best and ruthless at his worst.
  • Adaptational Wimp: In terms of authority, at least. Original series Adama led all of humanity, while this version only leads the military.
  • A Father to His Men: His troops look up to him, and he cares deeply for them. Ironically, he was probably more distant with his son than the rest of the troops under his command at the beginning of the series.
  • Authority Equals Asskicking: He's a skilled Viper pilot, despite his age and rank.
  • Badass Baritone: He has a deep, authoritative voice.
  • Beard of Sorrow: He's unshaven in "33" shortly after the destruction of the colonies.
  • Becoming the Mask: A few episodes show him putting on the mask of being The Stoic has left him unable to take it off, and with difficulty expressing emotion.
  • Big Good: Leader of the human military, though he shares this role with Laura Roslin who is leader of humanity as a whole.
  • The Captain: And is later promoted to Four-Star Badass.
  • Catchphrase: "Sometimes you gotta roll the hard six."
  • Chekhov's Gun: When shown shaving with his straight razor, Adama will always cut himself with it, symbolizing whatever turmoil he's feeling that episode.
  • Commanding Coolness: To the awesome power.
  • Combat Pragmatist: "The Adama Manuever".
  • Cool Old Guy: He gets along quite well with his younger crew, who affectionately refer to him as 'the old man'.
  • Crazy Jealous Guy: He gets rather jealous of how chummy original series Adama gets with President Roslin in the non-canon crossover comic.
  • Cultured Badass: Starts off every morning by reciting a poem.
  • Death Glare: A true master of this, also known as "The Adama Glare".
  • Fisher King: His deterioration in Season 4.5 eerily mirrors Galactica's own.
  • Four-Star Badass: Gets promoted over the course of the series, leading to him attaining the rank of Rear Admiral.
  • Guttural Growler: His callsign was "Husker" for a very good reason.
    • Although he gets that callsign in Blood and Chrome for a different reason: his war-weary partner sarcastically dubbed him "Husker" (as in "cornhusker") for being an overenthusiastic "farmboy".
  • Henpecked Husband: He was this to his wife Caroline, who spent her time verbally abusing him and generally turning his every action into another sign of his cruelty, out of love for her and because he genuinely thought she was right. Lee later stated his belief that she never actually loved him.
  • Hidden Depths: "A Day in the Life" shows he’s filled with self-loathing.
  • Like A Daughter To Me: He repeatedly says this to Starbuck. He has the same feeling, to a somewhat lesser extent, for Boomer, which explains a lot of his interaction (good and bad) with her and Athena. Shows shades of this in Season 3 with Kat as she is dying from radiation poisoning after saving a civilian transport.
  • Machine Empathy: He seems to be able to feel when Galactica is hurting.
  • Manly Tears: He has a full-blown breakdown when Tigh reveals to him that he's a Cylon. He sheds these again in the finale when Laura dies.
  • Mighty Glacier: On the few times he's seen in action, he's generally capable of felling an opponent with a slow deliberate punch.
  • Papa Wolf: Very protective of his crew.
  • Parental Substitute: For Starbuck.
  • Rank Up: Roslin formally promotes him to admiral following Cain's demise.
  • Reassigned to Antarctica: How he ended up in command of the Galactica in the first place, after a mission to spy on the Cylons aboard his previous command went horribly wrong. Court-martialing and discharging him would have publicly exposed the operation, so he was sent to serve on Galactica with the hope that he would take the hint and retire when the ship was decommissioned.
  • Reasonable Authority Figure: A very intelligent and perceptive man who is also excellent at directing and managing people around the ship.

     President Roslin 

Laura Roslin

https://static.tvtropes.org/pmwiki/pub/images/TropeRoslin_6473.jpg
"One of the interesting things about being president is that you don't have to explain yourself to anyone."
Played By: Mary McDonnell

The Secretary of Education under President Richard Adar, Laura Roslin was attending the de-commissioning ceremony on Galactica when the Cylons attacked (as the ship was to be turned into a museum). Forty-third in the line of succession, she was sworn in as the lawful replacement President of the Twelve Colonies. Immediately other characters began to snark about having a kindergarten teacher for a president, but Roslin handled the office with more aplomb than even her supporters could have expected.

  • Baldness Means Sickness: Laura Roslin eventually loses her hair due to cancer treatments. She usually wears a wig while in public and a scarf while in private or while exercising.
  • Big Good: As President of the Twelve Colonies, she shares this role with Adama who leads the military.
  • Canon Foreigner: She had no equivalent in the original series, where President Adar was succeeded as leader of the Colonials by Adama himself under martial law.
  • Deadpan Snarker: Has a very sarcastic sense of humor.
  • Death by Origin Story: Her father and two younger sisters died in a car accident. After grieving for several months, she agreed to become part of Adar's campaign for President as a way to move on. It set everything in motion for her eventual arrival on Galactica.
  • Fiery Redhead: She is fierce and more than willing to talk back to anyone who questions her.
  • Glasses Girl: Almost never seen without her iconic set of wire-frame glasses.
  • Hanging Judge: She really likes doing this early on.
  • Heroes Want Redheads: She's Adama's Love Interest.
  • Ill Girl: She's an older example, but still suffering from cancer nonetheless.
  • Iron Lady: She's far more stern than her opposition expects from a "kindergarten teacher."
  • Jerk with a Heart of Gold: Roslin can be a downright ruthless pragmatist, but also has a strong empathetic side and is firmly dedicated to safeguarding the survival of mankind and reaching Earth.
  • Pointy-Haired Boss: Shows some signs of becoming this by early Season 4, by which point she openly regards the Quorum of Twelve as a nuisance rather than a body she's answerable to, passes laws without consulting the Quorum and is openly disdainful towards them whenever they question her decisions. Admittedly, it's somewhat understandable since on top of all the usual stresses of her job her cancer has returned by this point.
  • Our Presidents Are Different: She is definitely President Iron. When pushed too far, she becomes President Action. Her belief in the Pythian prophecies causes some to think of her as President Lunatic. She crosses the line into President Scheming once by allowing her cabinet to fix an election. The plan falls through, however.
  • Reasonable Authority Figure: For the most part, though she also proves herself to be disconcertingly manipulative as the series goes on.
  • Secretly Dying: Is diagnosed with terminal breast cancer in the Miniseries which she initially hides from the vast majority of her citizens in order to keep some measure of stability. It slowly gets worse over the course of the series and eventually kills her.
  • Team Mom: Spends a lot of her time as President trying to stop the constant infighting and backstabbing that's endemic among the survivors. She can be very stern - even ruthless - when necessary though.
  • The Topic of Cancer: Her illness.
  • Trauma Conga Line: The opening Miniseries time span - First she discovers she has cancer, then the Cylons launch their devastating attack which kills just about everyone she knew, and then she's thrust into the role of President. Really, it's no surprise that she's breaking down into tears while being sworn in as President.
  • Unexpected Successor: Forty-third in line, even.
  • Warhawk: Roslin's humble origins belie her ruthlessness, particularly in contrast to Adama. Between the two of them, she is more likely to resort to extreme measures, such as advocating the assassination of Admiral Cain and using biological weapons against the Cylons.
  • Well-Intentioned Extremist: Has committed acts of terrorism, meddled with democratic elections, and had people executed in order to safeguard mankind's future.

     Starbuck 

Lieutenant Kara Thrace (callsign: Starbuck)

https://static.tvtropes.org/pmwiki/pub/images/TropeThrace_7567.jpg
"Pilots call me Starbuck, you may refer to me as God."
Played By: Katee Sackhoff

An excellent pilot considered the best shot and manueverer in the squadron, with a rebellious streak a mile wide. This makes her genuinely awesome, both in and out of the cockpit... though the show also deconstructs just what happens when you have a genuine Military Maverick on your hands. The Cylons, particularly Twos, claim that she has a "special destiny," and ultimately she uses Magic Music to lead the fleet to Earth. ...After dying and being returned as some sort of Angel Unaware.

  • Abusive Parents: She was raised by her mother, a divorced Colonial Marines NCO repeatedly rejected from officer training, who took out her frustrations on Kara by doing things like slamming the door on her fingers. In a somewhat unusual variation, rather than calling Kara useless or so on, Socrata Thrace believed she was special and criticized her for not living up to her full potential.
  • Ace Pilot: One of the best on the show.
  • Action Girl: Since The Main Characters Do Everything, even though she's an Ace Pilot, she's also skilled as infantry/SWAT.
  • Broken Ace: Even before the vast majority of the fleet was killed, she was one of their best pilots. However, she has stunted her own career by accumulating demerits from bad behavior, and is eventually revealed to have an extremely dark past and a lot of accompanying emotional baggage that cause her sanity and composure to begin to break down multiple times throughout the series.
  • The Alcoholic: While she's a relatively high functioning alcoholic as compared to Col. Tigh, she still drinks far more than is healthy and Katee Sackhoff herself once stated that Kara "drinks most of her calories".
  • Ascend to a Higher Plane of Existence: Her ultimate fate.
  • Back from the Dead: Played with. While the being that appeared at the end of Season 3 certainly believed herself to be Kara, it's hinted that she was not the original Kara, but was actually an angelic entity sent by "God" to lead the Colonials to Earth-2.
  • Blasphemous Boast: While training the new pilots in Season 1, she orders them to refer to her as "God" in order to intimidate them.
  • Blood Knight: As evidenced by this quote:
    "You know, everyone I know is fighting to get back what they had. I'm fighting because I don't know how to do anything else."
  • Boom, Headshot!: Shot the Raider she hijacked in Season 1 right in its bio-mechanical eye. While both of them were flying in space.
  • Boyish Short Hair: Kara often wears her hair this way, and most noticeably in the Miniseries and Season 1.
  • Broken Bird: Her dad left, her mom was an abusive hardass, and her fiancé died in an accident she indirectly caused - and that was all before the Cylons attacked. Her high amount of unprocessed trauma ends up pushing her into risky or borderline suicidal behavior often enough that her extreme recklessness is a major part of her character, up until she actually does die; when she returns, she is still somewhat unhinged for different reasons but puts herself at far less needless risk.
  • Career-Ending Injury: Pre-series. Kara was on track to become a professional Pyramid player until a knee injury prematurely ended her career.
  • Cartwright Curse: Zak ends up dead as a result of her passing him through a test he failed, while Sam is first left behind on an irradiated Caprica, then later rendered brain-dead by a bullet to the head. At the very end, when it looks like she finally has the chance to be with Lee, she disappears into thin air, leaving him behind.
  • Cigar Chomper: A rare female version.
  • Crazy Is Cool: Deconstructed over the course of the series, as she initially seems to be a straight example of the trope but is eventually revealed to be a badly traumatized person with extreme self-destructive tendencies that often harm both herself and those around her.
  • Daddy's Girl: She was much closer to her pianist father Dreilide than her abusive and unpleasable mother Socrata, though he later abandoned them.
  • Death Seeker: A major recurring element of her character until the end of season 3, and comes into direct focus in the episodes "Scar" and "Maelstrom."
  • Freudian Excuse: The constant physical abuse Kara suffered at the hands of her mother, coupled with her father's abandonment of her, goes a long way towards explaining why she's so dysfunctional as an adult.
  • Gender Flip: Starbuck in the original series was a man. Here, Starbuck is a woman.
  • Good Bad Girl: Due to being a Distaff Counterpart to her womanizing namesake from the original series.
  • Heroic BSoD: Goes through one after realizing that she's not a mortal human anymore.
  • Hidden Depths: She's actually a pretty decent pianist. She learned how to play from her father before he left her, and she claims that the chorus to "All Along The Watchtower" is one of the few things that makes her happy.
  • Inferiority Superiority Complex: For as much as she may bluster and arrogantly boast to her peers, she has severe self-loathing issues and views herself as unimportant.
  • Jerk with a Heart of Gold: She's often rude, insensitive, hostile and insubordinate which can occasionally lead her into conflict with other officers onboard the Galactica, particularly Col. Tigh. However, she is broadly well-intentioned and values human life, takes her job (as a pilot) seriously, is a genuinely good flight instructor, and can be kind and affectionate with people she cares about (such as Helo, one of her oldest friends in the Fleet, and Apollo).
  • The Lad-ette: Drinks, chomps cigars, and generally acts like One of the Boys.
  • Lady Swears-a-Lot: Probably the most foul-mouthed character in the cast. Rarely goes an episode without uttering some form of profanity.
  • Meaningful Name:
    • Kara is the name of a Valkyrie in Norse mythology. Meanwhile, Thrace refers to a Celtic tribe living northeast of Greece during ancient history who known for being very warlike and were often employed as mercenaries, to the point where they were said to be descended from a son of Ares.
  • Military Brat: Kara's mother Socrata was in the military and she spent most of her childhood traveling from one colony to another.
  • Ms. Fanservice: Sometimes plays this role in the first couple of seasons due to her habit of lounging around in her underwear, although she's nowhere near as straight an example as Head Six.
  • My Greatest Failure: She blames herself for Zak's death.
  • Not Afraid to Die: As shown in one of her earliest flashbacks in the finale, she has no fear of death. Her recklessness is sometimes framed more positively as part of what makes her "cool," but ultimately it's a symptom of the deep feelings of worthlessness that were instilled in her by her mother, and begins edging toward Death Seeker territory as her emotions become harder for her to manage.
  • Our Angels Are Different: It appears that she was resurrected as an angel-like entity akin to Head-Six and Head-Baltar after her death, albeit where everyone can see her.
  • Platonic Life-Partners: She and Helo have been close friends for a long time.
  • Psychotic Smirk: Katee Sackhoff has the most frighteningly ambiguous smile in science-fiction TV since Paul Darrow as Avon in Blake's 7 (and uses in it rather similar circumstances).
  • Rank Up: To captain and CAG eventually.
  • Really Gets Around: Sleeps with anyone she fancies, even after she's married. Deconstructed in that she apparently has a habit of using sex to self-sabotage, such as when her relationship with Lee starts to move toward romantic territory at the Colonial Day celebration but she then turns around and sleeps with Baltar instead, despite very obviously still preferring Lee. When Lee later confronts her and asks for an explanation, she doesn't have one.
    Lee: Why'd you do it, Kara? Just tell me why.
    Kara: 'Cause I'm a screw-up, Lee, try and keep that in mind.
  • Religious Bruiser: Surprisingly, one of the most devoutly religious characters on the show (even more so than Roslin, who has religion as a central element of her character arc). Although she plays fast and loose with societal rules, Kara takes religious sacraments and the gods in general extremely seriously – hence why she is willing to cheat on her husband Sam with Lee, but balks when Lee suggests the possibility of divorcing Sam.
  • Screw Yourself: Literally. She sleeps with original series Starbuck in the crossover comic.
  • She's Back: After spending the beginning of Season 4 steadily unravelling, Sgt. Matthias's death results in her snapping back to her tough-as-nails usual self.
  • She Cleans Up Nicely: Invoked by name in "Colonial Day", in fact.
  • Star-Crossed Lovers: With Apollo.
  • Teacher/Student Romance: She was Zak's flight instructor, girlfriend and eventual fiancée.
  • Tomato in the Mirror: She's understandably distraught upon learning that she's almost certainly not a human after being resurrected.
  • Walking Spoiler: After being brought Back from the Dead, she's actually an "angel" like Head-Six and Head-Baltar with the purpose of helping make sure everyone finds the new Earth.
  • Wrench Wench: Has a few moments, most notably when she somehow managed to get a Cylon Raider in working condition after being forced to eject from her Viper and landing on a nearby moon.

     Apollo 

Captain Leland Joseph Adama (callsign: Apollo)

https://static.tvtropes.org/pmwiki/pub/images/TropeLeland_3646.jpg
"I'm the coward. I'm the traitor. I'm forgiven."
Played By: Jamie Bamber

The son of Bill Adama, from whom he is estranged due to the death of his younger brother Zak. Apollo's opinion is that Adama pressured Zak into becoming a pilot, which Zak was not ready for; he blames his dad for his brother's death. He also takes after his grandfather (lawyer Joseph Adama) in being rather more loyal to laws, rights and civil liberties than the uniform or any group of people. Ordered to Galactica at Bill's request to lead the ceremonial flyby for the decomissioning at the start of the series, Lee becomes the senior pilot (Commander of Air Group) after the previous CAG dies during one of the first engagements with the Cylons. Eventually promoted to Commander, put in charge of the Pegasus, and wed to Dee.

  • The Ace: Lampshaded by his callsign, as Apollo is The Ace in this universe's pantheon.
  • Adaptational Angst Upgrade: Lee has a far rockier relationship with his father than the original series Apollo; when the series opens, they're outright estranged from one-another.
  • The Big Damn Kiss: During what he thinks may be his final goodbye to Starbuck in "Six of One."
  • Calling the Old Man Out: Does this many times to his father Bill, for getting Zak killed trying to live up to his expectations and also for being absent through much of their childhood and leaving them with their mother Carolanne, who became verbally abusive when she'd had too much to drink.
  • Cartwright Curse: His pregnant girlfriend gets killed in the Cylon attacks, Starbuck gets married to Anders right after finally admitting she loves him, and before eventually dying, he has a rocky relationship with Dee before separating from her and she commits suicide. Lee is not lucky in love.
  • Commanding Coolness: Spends the first half of the series as Galactica's CAG (Commander of Air Group).
  • Did Not Get the Girl: In the Grand Finale, when it seems like he and Kara may finally be able to get together, she vanishes.
  • Knight in Sour Armor: Lee has a pretty low opinion of many people, constantly calling them out for falling short of their ideals. He is hardest about this on himself. Still, he is also one of the few people in the series who will most reliably choose to do the right thing, no matter how many people he pisses off and no matter how badly he believes it will backfire on him.
  • Living Emotional Crutch: To Kara, as he's almost always the one checking on her, helping her talk through her thoughts and feelings, and telling her off when she's being callous or putting herself or others at unnecessary risk. Notably, when she finds her own corpse on the destroyed Earth, the first thing she does is go to Lee to tell him about it.
  • Meaningful Name: "Lee" is of Old English origin, and means "pasture" or "meadow." Lee is the one who comes up with a "return-to-the-land" plan in the finale.
  • Military Brat: Comes with being Adama's son.
  • Mr. Fanservice: He's got a lot of shirtless scenes showing off his Heroic Build.
  • Platonic Life-Partners: With Starbuck, or so they claim.
  • Rank Up: Initially to Galactica CAG, then XO and later Commander of Pegasus, and eventually Vice President of the Twelve Colonies
  • The Reliable One: Lee is a skilled pilot and natural-born leader and while he has his share of problems, he's definitely closer to having his shit together than his comrades (most notably Starbuck).
  • Sharp-Dressed Man: When he leaves the service and gets into politics.
  • Star-Crossed Lovers: With Starbuck.
  • Straight Man: He serves as something of a straight man for the entire crew.
  • Strong Family Resemblance: Is noted by Ellen Tigh to look a lot like his mother, Carolanne Adama.
  • The Main Characters Do Everything: Lee is practically the embodiment of this trope. There are few military/leadership roles that he hadn't assumed or temporarily performed at one point or another during the show.
  • "Well Done, Son!" Guy: A major part of his interactions with his father.
  • Will They or Won't They?: A solid three-and-a-bit season's worth with Starbuck, putting them at the center of a mad-crazy Love Dodecahedron (Starbuck loves both Lee and Anders; Lee loves both Starbuck and Dee; Dee loves both Lee and Billy).
  • Would Hit a Girl: Is perfectly willing to strike back when Starbuck decks him.

     Gaius Baltar 

Dr Gaius Baltar

https://static.tvtropes.org/pmwiki/pub/images/TropeBaltar_6376.jpg
"You have not heard the last! No more Mr. Nice Gaius!"
Played By: James Callis

A genius scientist working on a new navicomputer program for the Colonial military, Baltar was unwittingly instrumental in the Cylon massacre: he was seduced by a Number Six who he believed worked for a competing defense contractor, and gave her access to the program, into which she inserted a virus which managed to disable most of the fleet. Surviving via luck and reputation, Baltar now has to negotiate the fleet while keeping his betrayal secret. There's also the fact that he now holds conversations with his version of a Shoulder Angel, another Six copy. Becomes President on the platform of insisting that the fleet colonize a semi-habitable planet called New Caprica, which turns out to be a huge mistake.

  • Adaptational Angst Upgrade: Unlike original series Baltar, he feels incredibly guilty about inadvertently selling humanity out to the Cylons.
  • Adaptational Attractiveness: In the original series, Baltar was an older man with the Face of a Thug. The reimagined version borders on being a Pretty Boy.
  • Adaptational Heroism: In the original show, Baltar was The Heavy for the Cylons and served as the de facto main antagonist for the show, was a deliberate traitor to the human race, and at times was arrogant enough to believe that the Cylons worked for him rather than the other way round. Here, he is an Anti-Villain at worst, was only tricked into helping the Cylons destroy the colonies, and while definitely selfish, cowardly and an all-round Jerkass, he is never truly evil and (very) slowly undergoes Character Development that sees him eventually become a more heroic person.
  • A God Am I: Has his moments.
  • Amazon Chaser: Head!Six says he has a thing for strong, powerful women, and over the course of the series, he sleeps with Kara and has an Erotic Dream about Roslin.
  • Anti-Hero: At his best of days.
  • The Atoner: He is trying to undo the damage he caused by letting Caprica-Six seduce him, though it's more out of self-preservation.
  • Beard of Evil: Doubles as Beard of Sorrow, and Beard Of Ineffectual Cowardice - to cut it short, whenever Baltar changes his facial hair style, major charter development is inbound.
  • Brilliant, but Lazy: He's one of the smartest men alive but would much rather spend his time sleeping around and smoking cigars.
  • Bunny-Ears Lawyer: He's awkward, cowardly and talks to himself but is probably the smartest man left in the universe.
  • Butt-Monkey: Quite often.
  • The Caligula: During his Presidency of New Caprica he indulged in alcoholism, womanizing and wallowed in the incompetence of his subordinates while his people suffered and died. After the Cylons take over New Caprica and turn him into a puppet king, he winds up being the Only Sane Man in the whole administration, because the Cylons are just that terrible at running a government.
  • The Casanova: It would be easier to count the women he hasn't slept with.
  • Celebrity Survivor: Easily one of the most famous and recognizable figures to escape the Cylon holocaust (which is more than a little ironic, considering he’s inadvertently responsible for it). Helo even gives up his seat on the Raptor for him because of his status as a renowned genius scientist, and he’s elected as Caprica’s Quorum of Twelve delegate without even having sought the position.
  • Deadpan Snarker: You couldn't go through everything he does without developing a sense of humor about it.
  • Defiant to the End: In the later seasons, Baltar develops the surprising tendency to do this, to the point of baiting Gaeta into trying to kill him due to his Sanity Slippage.
  • Dirty Coward: He takes crying, pleading for his life, and refusal to take responsibility for himself to a whole new level. Though he did get better.
  • Even Evil Has Standards:
    • It would be a real stretch to call him evil (though cowardly and narcissistic are very much fair descriptions). Still, he was absolutely horrified at Admiral Cain's appalling treatment of a Cylon prisoner.
    • When Roslin asks him if he will be endorsing the increasingly popular Tom Zarek for the office of the Vice-Presidency, Baltar tells her, in a rare moment of sincerity, that he would never support someone politically who advocates violence as a means to get his message across.
  • Freudian Excuse: It's implied that his ego and personality stems from his insecurities about being a native of Aerilon, widely regarded as a backwater colony, and having to hide this fact after moving to Caprica so people would take him seriously.
  • Handsome Lech: He attracts women fairly easily, but can be quite the perv.
  • Happily Ever After: The Grand Finale implies this of him and Caprica-Six.
  • Heel Realization: At the beginning of Season 4, Baltar finally realized the severity of the consequences of his actions, and is overwhelmed with guilt. He even demands that God take his life instead of a young child, something that is usually unthinkable for Baltar to do. Played With, as he then develops a messiah complex and starts backsliding into his old ways, then realizes what's happening, and finally decides to commit to a Heel–Face Turn and do good around the fleet, then backslides again, then has another Heel Realization.
  • Heel–Face Turn: Double Subverted. Baltar initially seems to be faking it after he gets his own cult in Season 4, simply gratifying his own ego, but it's eventually revealed that Baltar is entirely genuine about it and is just trying to atone for his actions. By "Deadlock", he's developed into the only person keeping peace aboard the ship by helping out civilians and keeping riots from breaking out over Galactica becoming a blended ship of humans and Cylons. He then relapses back into selfishness the next episode, only to have another Heel Realization in the Grand Finale and gives up his cult, before remaining on Galactica for the Final Battle against Cavil's forces.
  • Hidden Depths:
    • It becomes more and more clear as the series goes on he really did genuinely love Caprica Six. For her part, it was mutual, even if she happened to be using him.
    • Tyrol at one point laughs when Baltar says in his autobiography that he was born on a farm on Aerilon, only for Baltar to get irritated and reveal that he was. He also reveals he worked to hide his native accent to make people think he was Caprican, (which he points out was very difficult) because he feared nobody would take him seriously if they realized he was from a poor, 'backwards' world.
  • Hookers and Blow: The Baltar administration was marked by its groundbreaking lap dance and pill-popping initiatives.
  • Hot Scientist: It's easy to forget he's a brilliant scientist.
  • Indy Ploy: The first couple of seasons have him making things up off the cuff, like his Cylon screening technique. Later on, he bullshits an entire religion as he goes. Though amusingly, he was actually spot on with his religion.
  • Insufferable Genius: At times. He's a genius and doesn't mind reminding others.
  • It's All About Me: Six is so impressed by his self-centeredness that she thinks it would be worth taking a copy of his brain for further study. He becomes less selfish as the series goes on, however.
    Six: Even as the fate of your entire species hangs in the balance, all you can think about is how this affects you.
  • It's All My Fault: When he admits to Roslin, when it's just the two of them, while delirious, seriously injured, and high on morphine, that he unintentionally gave the Cylons access to the defense mainframe, and is therefore partially to blame for the Fall of the Twelve Colonies and absolutely everything that came after. He's practically on the verge of tears while saying this, and it's clear that he's never really forgiven himself for what part he played in the nuclear holocaust.
  • Jerkass Has a Point: Baltar may be a power-hungry opportunist who didn't have the fleet's best interests in mind at the time, but he's not wrong when he chews out Roslin for conspiring with the military to steal a democratically-held election from him, particularly when she herself is a leader nobody elected to begin with.
  • Jerk with a Heart of Gold: Despite being an Insufferable Genius who was in part responsible for the near-annihilation of mankind, he's quite compassionate and emotional, firmly believing that war is not an excuse for inhumanity.
  • Large Ham: He definitely has his moments, particularly in Season 4 whenever he starts making speeches to his followers.
  • The McCoy: He's probably the most emotional person in the series.
  • Messianic Archetype: In-Universe, with him becoming the central figure of a cult in Season 4.
  • Misplaced Retribution: He's on the receiving end of this following the Cylon occupation of New Caprica. Several people try to murder him over the crimes committed by the Cylons, which he, for all his faults, was not responsible for.
  • Morton's Fork: Lee Adama was right. Given the circumstances of the Cylon occupation of New Caprica, just what was Baltar supposed to have done?
  • Mr. Fanservice: Has several erotic sex scenes and cleans up nicely.
  • Narcissist: Although he gets better througout the series, he remains pretty self-absorbed. He starts off as an Insufferable Genius, not caring much about anyone but himself. He goes on to run for President of the Twelve Colonies pretty much for an ego trip. After having a crisis of guilt, he eventually discovers religion and quickly develops a Messianic complex.
  • Never My Fault: Adama believes this to be the case, flat-out saying that Baltar can never take responsibility for his actions because he will always see himself as the victim. The truth is more that he is in extreme denial.
  • OOC Is Serious Business: When the Cylons attempt to make him sign a death list during the New Caprica occupation, he flat-out refuses, even after Doral puts a gun to his head and makes it clear he will be killed if he doesn’t sign it. Head Six only barely talks him into giving in and signing it, and it’s pretty clear that the usually cowardly Baltar would have let himself be killed if it weren't for that.
  • Omnidisciplinary Scientist: Since The Main Characters Do Everything, he's basically in charge of "science" on the Galactica, including computer science, biology and nuclear physics. Well, there's a reason he was considered one of the greatest minds in the Colonies.
  • Only Sane Man: To the Cylon administration during the Cylon occupation of New Caprica. He's literally the only one who thinks that rounding people up and making death lists is a terrible idea, especially if the Cylons want to be accepted. They ignore him.
  • Pet the Dog: Praying to God to take his life instead of that of a kid and actually meaning it.
  • Plucky Comic Relief: His interactions with "Head Six" (aforementioned Shoulder Angel) are often in public and frequently Played for Laughs.
  • Rage Against the Heavens: In Season 4, after Earth is discovered to be a nuclear wasteland, Baltar goes into a public tirade against God for giving them false hope and all the suffering they were put through.
  • Really Gets Around: Pre-series he had numerous liasons and during the course of the series he's slept with at least Starbuck, Playa Palacios, Tracey Anne, several interns while he was president, and also seems to have a thing for Cylons, having been with D'Anna Biers, Tory Foster, and three different versions of Number Six (Caprica-Six, Gina Inviere and Lida; and Shelly Godfrey apparently had a crush on him), four if you count Head-Six, as well as flirting with Boomer in Season 1.
  • Religious Robot: Inverted; he's a missionary spreading Cylon monotheism to the humans.
  • Sanity Slippage: In "Taking A Break From All Your Worries", his nightmarish interrogation manages to cause his already frayed sanity to deteriorate further, to the point of actually trying to bait Gaeta to kill him.
  • The Scapegoat: For the Cylon occupation of New Caprica. While Baltar’s initial presidency was terrible, throughout the Cylon occupation he was the Only Sane Man in the administration and was forced into going along with the Cylons’ plans, even secretly undermining them by allowing Gaeta to leak information to the resistance. Still, his lack of any public display of resistance to the occupation results in him being blamed for all of the suffering on New Caprica.
  • Self-Made Man: He was born poor on a farm on Aerilon (considered a backwater colony), moved to Caprica when he turned eighteen, and became one of the leading scientific minds of the century and, from the looks of his home at the start of the Miniseries, filthy rich. Whatever his flaws, nobody gave this man anything in life for free.
  • The Smart Guy: Initially, he's pretty much the source of all scientific advancement aboard the Galactica, and is also tasked with additional research and information gathering unrelated to his main focus of Cylon technology (such as when he calculates exactly how much food and water the fleet will need in order to survive). He may have a lot of personal flaws, but he can easily accomplish almost any intellectual task that's placed in front of him, and is clearly exactly as smart as he thinks he is.
  • Took a Level in Badass: He steps up in later seasons until he's part of the Galactica defense team in the finale, repelling the Cylons with an assault rifle.
  • Took a Level in Kindness: After becoming a religious figure, Baltar does his best to invoke this because he genuinely wants to atone. He goes through some improvements and some backsliding, only to finally commit to this in the Grand Finale.
  • Villain Ball: A lot of the second half of the series plays out the way it does simply because Baltar is way too into himself to actually learn from his mistakes. Scheming and sleazing his way into the presidency by promising the desperate fleet he will settle New Caprica (which he seemingly does solely for power, as he admits in private that the planet is barely even habitable) sees thousands of people killed, Pegasus destroyed, and Galactica damaged so badly she later has to be abandoned. He's also the one who (idiotically) gave the damaged and suicidal Gina a fucking nuclear bomb only for her to use it and destroy several ships filled with civilians, which creates the radiation signature The Cylons eventually use to find the humans again in the first place. And he spends the entire New Caprica arc being about as useless as humanly possible.
  • Villain Protagonist: Deconstructed - Baltar isn't evil, just selfish and cowardly (i.e., not a hero like most of the other cast).

Battlestar Galactica Military

     Colonel Tigh 

Colonel Saul Tigh

https://static.tvtropes.org/pmwiki/pub/images/TropeTigh_6490.jpg
"If the crew doesn't hate the XO, then he's not doing his job."
Played By: Michael Hogan

After Bill Adama was mustered out from the first Cylon war and began serving on a commercial freighter, he met a fellow veteran named Saul Tigh, and the two formed a deep friendship. When reinstated, Adama pulled strings to have Tigh brought in as his second-in-command. Tigh is an alcoholic who is often Off the Wagon, and is probably the series' biggest bearer of Fantastic Racism against the Cylons (with Starbuck as a close second). How amusing, then, that he's one himself - To be more precise, he's one of the Final Five.

  • Adaptation Species Change: The original series Tigh was human.
  • Adaptational Jerkass: A lot of characters are this compared to their original series counterparts, but Tigh is second only to Cain in this regard.
  • Achilles in His Tent: After New Caprica, he becomes a drunk wreck for a while.
  • The Alcoholic: He puts the "fun" in "functional alcoholic." And his wife just makes him worse.
  • Aw, Look! They Really Do Love Each Other: Saul and Ellen very much have this dynamic.
  • Bald of Awesome: He's bald and awesome.
  • The Caligula: During his brief stint as commander of the fleet, he is extremely harsh, violent, and unstable, partially because he has no idea how to handle the responsibility, partially because he's constantly drunk, and partially because of his scheming, psychotic wife. He’s painfully aware of this and makes it clear the entire time that he really doesn’t want his position.
  • Colonel Badass: He's certainly competent, and he serves his role well.
  • The Creon: Takes command of the Galactica only when Adama is shot, and gives it back immediately as soon as possible. He never plots against Bill Adama for a second, even when he has serious issues with his commander's behavior. He even outright says that it was always supposed to be them leading together, not him leading alone.
  • Eyepatch of Power: After he loses his eye on New Caprica.
  • Deadpan Snarker: "The President, Gods bless her sunny optimistic soul, thinks you might want to share how your buddies have been tracking us. So I'm here to ask the question and listen to your lies."
  • Dude, Where's My Respect?: Part of the reason for him Taking A Level In Jerkass is his anger at much of Galactica's crew's lack of acknowledgement or gratitude of everything the Resistance did during the Cylon occupation. He also gives this to Galactica's crew himself, who put themselves at considerable risk in rescuing the people on New Caprica, with the entirety of the Galactica crew nearly dying and the Pegasus being destroyed in the process.
  • Fake Guest Star: Tigh is in all but four episodes of the show. The only characters to appear more frequently were Laura Roslin and Bill Adama.
  • Fake Memories: His own history prior to the First Cylon War was fabricated by John Cavil.
  • Fantastic Racism: Seriously rivals Starbuck in terms of utter hatred for the Cylons.
  • Good Is Not Nice: Led a vigilante group that executed Cylon collaborators.
  • Heterosexual Life-Partners: If he and Bill Adama don't embody this trope, we don't know who does.
  • Humble Hero / Think Nothing of It: He's not very good at accepting gratitude, even from Adama himself. Whenever someone offers thanks or admiration, Saul just awkwardly states that he's only doing his job.
  • I Did What I Had to Do: The New Caprica arc.
  • Jerkass: At times it can be really hard to sympathize with Saul.
  • Jerk with a Heart of Gold: But he's still a good man at heart.
  • Jerkass Has a Point: After the Cylons attack, he tells Boomer he was aware of her relationship with Tyrol, but let it slide because Galactica was in the process of being decommissioned and things were therefore Mildly Military at the time, anyways. He then tells her things have changed since then and orders her to break it off, as an officer and the ship's senior NCO being in a relationship together is just a flat out bad idea.
  • The Lancer: To Bill, but is a deconstruction. He is awesome as a second in command, but almost no one (most of all him,) ever wants him to be the number one of the fleet's command. He excels at being Bill's number two, but is completely useless in any other capacity. This is inverted though, when he redeems himself by effectively leading the New Caprican resistance, even if his tactics are... somewhat suspect.
  • Manly Tears: Most notably, when he killed his wife.
  • Meaningful Name: The Biblical Saul lost his sight on the road to Damascus, only regaining it when he stopped persecuting the monotheistic Christians. Saul Tigh had his eye plucked out by Cavil as punishment for his guerrilla war against the monotheistic Cylons.
  • Number Two: To Adama.
  • Pick Your Human Half: Deconstructed, in a sense at least, after he learns that he's a Cylon. Unlike Tyrol and the other Final Five, who learn to be more accepting of being Cylons, Saul never really embraces that part of his nature. As such, Saul isn't able to access the special Cylon abilities that they can and this puts him at a disadvantage when the Fleet forms an Enemy Mine with the rebel Cylons in Season 4.
  • Poisonous Friend: He's kind of hell on Bill's sanity, though he really doesn't mean most of it.
  • Race Lift: Original series Tigh was black. Saul is white.
  • Really 700 Years Old: Like the other members of the Final Five, he is technically well over two millennia old.
  • Reincarnation Romance: He and Ellen were married originally too, and somehow found each other again after Cavil wiped their memories.
  • Then Let Me Be Evil: While by no means evil, during the New Caprica arc, after being told that a suicide bombing would make the Resistance no better than the Cylons, he simply shrugs and proclaims, somewhat sarcastically, “Which side are we on? We're on the side of the demons, Chief. We are evil men in the gardens of paradise, sent by the forces of death to spread devastation and destruction wherever we go. I'm surprised you didn't know that.”
  • Took a Level in Jerkass: After being tortured by the Cylons, Tigh becomes even more of a Jerkass, committing countless morally questionable acts and repeatedly decreasing morale and insulting Adama and his command.
  • Undying Loyalty: To Adama; case-in-point, after Bill is shot by Boomer, Tigh takes command of the fleet and begins to behave in a increasingly dictatorial fashion, but as soon as Adama recovers, Tigh immediately cedes command back to him.
  • Walking Spoiler: He's a Cylon, and one of the Final Five.
  • You Are What You Hate: Hates the Cylons far more than almost anyone else in the Fleet, and is understandably infuriated when it turns out that he's one of the Final Five.

     Chief Tyrol 

Senior Chief Petty Officer Galen Tyrol

https://static.tvtropes.org/pmwiki/pub/images/TropeTyrol_2574.jpg
"All I know is if there is a God, he's laughing his ass off."
Played By: Aaron Douglas

SCPO Tyrol is in charge of keeping Galactica's birds flying. He's very much an everyman in his approach to things, and often finds himself in positions of being the Only Sane Man. He was carrying on with Boomer for a while. He's also one of the Final Five and a Cylon.

  • A Father to His Men: He cares about his deckhands, and when some had to be sacrificed to put out a fire, he carried bitterness about it for a few episodes. He really loses his cool when one of his deckhands deliberately ruins his own career (by lying under oath and later claiming responsibility for a security breach he had nothing to do with) to cover for Tyrol's illicit relationship with Boomer. This finally causes him to break up with her for good:
    Tyrol: I put everything on the line for you. Everything. I cover for you, I protect you. I risk my career, my freedom, my integrity, for what? So some innocent kid, one of my kids, can take the fall for me? NO! We are not worth that.
  • The Aloner: In the series finale he decides he's had enough of both humans and Cylons. When the survivors settle on Earth he heads out on his own, telling the Tighs he wants to be as far away from everyone as he can get. It's implied that he ends up in what will become Scotland.
  • Ascended Extra: Tyrol was originally intended as a Flat Character, expanding primarily due to Aaron Douglas' ability to throw in dialogue, character names and other useful touches.
  • Butt-Monkey: Things go poorly for him, starting with his girlfriend being a Cylon.
  • Call to Agriculture: Rather ironically for a mechanic, it's mentioned that he takes to the Fleet's decision to Let the Past Burn on Earth-2 quite well since he wants to put as far of a distance possible between himself and his past.
  • Cartwright Curse: He is just not lucky in love.
  • Despair Event Horizon: Seems to have fully crossed this by the time of the Series Finale.
  • Fake Guest Star: Like Tigh and Helo, he's there from beginning to end, and missed only 7 episodes over the show's run.
  • Hot-Blooded: Especially on New Caprica, where his speech to the people was modeled after real life labor speeches.
  • Important Haircut: Shaves his head during the fourth series while in mourning after Cally's death.
  • Jerk with a Heart of Gold: Tyrol can be a real hardass, but he's overall quite considerate and has a strong sense of honor and loyalty.
  • Number Two: As the highest-ranking NCO in the fleet, Tyrol has aspects of this.
  • Pick Your Human Half: Inverted. Tyrol is by far the most accepting among the Final Five of their true Cylon nature, which lets him gain more access to their abilities such as Super Strength, Made of Iron, and being able to hack into networked computers.
  • Mr. Fixit: Chief mechanic.
  • Really 700 Years Old: Like the other members of the Final Five, he is technically well over two millennia old.
  • Reincarnation Romance: Inverted. He previously had a relationship with Tory Foster on Earth-1, but he ultimately strangles her to death after he learns that she killed his current wife Cally.
  • Stoic Spectacles: In his original life.
  • Took a Level in Jerkass: Not surprising, given the Trauma Conga Line he went through.
  • Trauma Conga Line: In a very short amount of time, he finds out he's a Cylon, his wife apparently commits suicide over it, he finds out that his baby isn't even his, and then he learns a former lover actually killed his wife. And then he ruins the Cylon-Human alliance by reacting to that information.
  • Walking Spoiler: He's a Cylon, and one of the Final Five.

     Helo 

Lieutenant Karl C. Agathon (callsign: Helo)

https://static.tvtropes.org/pmwiki/pub/images/TropeAgathon_1332.jpg
"Symbols matter. Uniforms, flags, banners - even mascots. They're like pieces of your heart that you can see."
Played By: Tahmoh Penikett

A Guy in Back in a Colonial Raptor, flying under Sharon "Boomer" Valerii, whom he kind of has a thing for. During the pilot miniseries, their ship lands on Caprica and Helo abandons his copilot seat to save Gaius Baltar. That was meant to be the end of this Mauve Shirt, but fan reaction to him was so positive that RDM and David Eick decided to keep following his adventures, which involve being rescued by another Sharon copy. With her, he becomes the father of "Hera," the first human-Cylon hybrid; he also serves as Adama's Number Two while Tigh is stuck on New Caprica.

  • Ascended Extra: He was supposed to be written out at the end of the Miniseries.
  • Beware the Nice Ones: He does kill a man for trying to rape his wife.note 
  • Fake Guest Star: Appears in the Pilot Episode, the Grand Finale, and all but eight episodes in between. For the record, starring actress Grace Park missed the same number.
  • The Fettered: He has issues, but they make him among the most normal in the cast.
  • Happily Married: After her Heel–Face Turn, he and Athena come to have perhaps the most stable relationship on the whole show.
  • Heroic Sacrifice: What he intended by giving up his seat on the Raptor to Baltar (he thought that a genius scientist was more valuable to human survival than a pilot). Of course, he survived.
  • Heterosexual Life-Partners: Has shades of this with Lee.
  • Honor Before Reason: Like Lee, he can always be counted on to do the right thing, but with more of a focus on people than the state of Colonial law and democracy, nor is he as willing to cross certain lines, such as when Lee advocates using a virus to wipe out the Cylons and Helo not only argues against it but sabotages the effort.
  • Knight in Shining Armor: Not quite as much as Lee though.
  • Meaningful Name: His last name means "good", "noble", and various other meanings of one's better nature. He's one of the least morally corrupted people out of the entire series' cast of characters.
    • It's unclear what the meaning of his callsign is. It could stand for "Helios", the god of the sun, or be a reference to military slang in which a "helo" is a helicopter and a "boomer" is a submarine.
  • Mr. Fanservice: Has an erotic sex scene with Athena in Season 1 and also has a Heroic Build. In-Universe, Number Six comments on his attractiveness to Athena, who pretends to be blasé, and Racetrack suggests using him for some R&R.
  • Mysterious Middle Initial: It's never revealed what the "C." in "Karl C. Agathon" stands for.
  • New Job as the Plot Demands: Since his primary role is "the guy who married a Cylon," he's free to take whatever position is needed to be filled for the sake of the episode. He goes from ECM officer on a Raptor, to XO, to "mayor of Dogsville", to XO...
  • Only Known by Their Nickname: He's much more often called "Helo" than "Karl". In fact, when a character does call him "Karl", it usually means the situation is serious.
  • Nice Guy: One of very, very few in the show.
  • Papa Wolf: Especially to Hera. When a dying Roslin tries to order the termination of Sharon's pregnancy Helo nearly pulls his sidearm on Adama to try and get the old man to back down.
  • Platonic Life-Partners: With Starbuck; notably, despite how she Really Gets Around. Though the actress said there may or may not have been a one-night stand at some point in the past. They've been close friends for a long time.
  • Really Gets Around: Implied in the Miniseries when he says he was on Gemenon visiting a girl he knew, and Boomer says, "What girl don't you know?" A bit of Early Installment Weirdness because this characterization never comes up again, but after all, he does spend the rest of the series in a committed relationship with Athena, so it wouldn't. (And he wasn't originally intended to survive when the Miniseries was written.)

     Gaeta 

Lieutenant Felix Gaeta

https://static.tvtropes.org/pmwiki/pub/images/TropeGaeta_1112.jpg
"I started this, and I'll see it through! Now get on that frakking ship!"

First appearing as a CIC watch officer, he eventually gets assigned to Dr. Baltar as a personal aide. He's an idealist—which is a bad thing to be in Galactica's World Half Empty; losing his leg in Season 4 is only one link in a "Break the Cutie" chain. Eventually leads a mutiny with Tom Zarek, which fails.

  • A Lighter Shade of Black: It's made explicitly clear that between him and Zarek during their mutiny, Gaeta is the one with genuinely positive motives while Zarek is only in it for the power.
  • Berserk Button: Immediately snaps and tries to stab Baltar in the neck with a pen when Baltar whispers something in his ear during an attempted interrogation. It's revealed in the webisodes that this was a mention of the Eight whom Felix knew on New Caprica, and that his over-the-top response was produced by a combination of blaming Baltar for everything that happened on New Caprica and an extreme subconscious resistance to examining the situation with the Eight too closely (because he knows deep down that she was lying to him the entire time and he inadvertently caused the deaths of almost everyone that he tried to save).
  • Break the Cutie: Idolizes Baltar, only to be disillusioned when the latter becomes an ineffectual, hedonistic President. Secretly provides information to La Résistance, only to be ostracized for his role in Baltar's administration and almost executed by a secret vigilante court. Later discovers his Cylon girlfriend on New Caprica was using him to identify members of La Résistance so they could be executed. Loses his leg due to an infected wound caused by a gunshot (not fired by the enemy, either). Loses all faith in Commander Adama after his alliance with the Cylons. Stages a coup, only for it to go badly wrong, resulting in several people getting needlessly killed, and ending with him being executed.
  • But Not Too Bi: He is canonically bisexual and has relationships with a man and a woman at different times, but neither of these relationships get any screen time in the show proper (they were explored in the show's webisodes). The only hint of his sexuality in the main story is his implied crush on Gaius. (Incidentally, no prizes for guessing how all three of these relationships ended.)
  • The Cast Show Off: invoked After the producers discovered that Alessandro Juliani is a fully-trained and highly-regarded operatic baritone, they found a reason for him to sing. Although it's actually quite sad when it happens in the series proper.
  • Dating Catwoman: Had a romantic relationship with an Eight while on New Caprica with whom he was working to get humans out of detention and to safety. Deconstructed in that it turned out she was mostly just using the lists he gave her of people to save as death lists, and she was staggered by just how easy it was to deceive him, specifically blaming his gentle, idealistic nature and his desperation to have faith in something. This culminates in Felix finally reaching his breaking point and deciding that humans collaborating with Cylons is unsustainable.
  • Deadpan Snarker: Particularly after losing his leg in Season 4.
  • Face Death with Dignity: His stoicism in the face of his own impending execution is inspiring and heartbreaking in equal measure.
  • Face–Heel Turn: Joins Zarek and instigates a mutiny in the final season.
  • Game Changer: Zarek was never able to take power (despite being legitimately elected) because he never had the support of the military. Gaeta ends up being the one to provide that support.
  • Hypercompetent Sidekick: During President Baltar's reign, which unfortunately makes him the fall guy for the later Cylon occupation.
  • Ironic Name: His first name means "happy" or "lucky". Poor Gaeta goes through a hefty Trauma Conga Line leading up to his Face–Heel Turn.
  • Kick the Dog: Lies under oath to get Baltar executed by claiming he signed a mass-execution order with no resistance or protest, when in fact he was not present to witness Baltar doing any such thing. (In actuality, the normally cowardly and self-serving Baltar outright refused to sign the order, and only did so after the Cylons literally put a gun to his head and forced him to; Felix assumes that he made no attempt at resistance because he was unresponsive when confronted with the death list later, and doesn't really care what the truth is because he considers Gaius guilty either way.)
  • Meaningful Name: He shares his last name with that of the city where the King of Naples was forced to capitulate during the War for Italian Unification, which made it the second-to-last independent city to fall before Italy was unified under one flag. As it would later turn out, The Mutiny he instigates is the second-to-last conflict in the series (with his mutiny being followed up by the Battle of the Colony in the Series Finale) prior to the melding of the surviving Cylon models, Colonial-humans, and second Earth-hominids under one hybrid species.
  • Mr. Fixit: A technological version. If the computers on board Galatica need fixing, Gaeta's usually the one to do it.
  • Nice Guy: Until he loses his leg, after which point he becomes much more bitter and harsh except toward close friends like Dualla.
  • Odd Friendship: Formed one with Gaius Baltar early on in Season 1, though it sadly gets torpedoed after the New Caprica occupation in Season 3.
  • Oh, Crap!: After Zarek executes the Quorom of Twelve, he's quietly horrified as he realizes that Zarek doesn't care at all for Gaeta's legitimately positive intentions regarding the mutiny and is only in it for the power.
  • Rule of Symbolism: His prosthetic limb only stops itching just when he decides to Face Death with Dignity and has accepted what he's done.
  • Slowly Slipping Into Evil: Gaeta is gradually broken by a massive Trauma Conga Line and becomes increasingly bitter as a result, which culminates in him snapping and leading a mutiny against Adama when he forms an alliance with the Cylons.
  • The Stoic: Keeps a cool head under almost any situation, which is frankly a bit of a requirement for someone in his position.
  • Surprisingly Realistic Outcome: His prosthetic leg is a depressingly realistic one, with it being very awkward for him to walk around with it, suffering from phantom limb pain, and constantly complaining of an irritating itch he feels where the prosthetic rubs against his leg stump.
  • Those Two Guys: With Dualla in a number of deleted scenes.
  • Well-Intentioned Extremist: When he leads a mutiny, he's doing it for what he sees as the greater good.
  • What the Hell, Hero?: His Kangaroo Court of his commander is basically Gaeta trying to force Adama to acknowledge what he put Gaeta through. Adama contemptuously refuses to play along as it's a show trial being conducted by a military coup, while Zarek is unable to convince Gaeta they need to concentrate on more pragmatic issues.
  • Wide-Eyed Idealist: Gaeta is a deconstruction, as from the start he is one of Adama's most loyal and capable officers. After Baltar (whom he greatly admires and becomes fast friends with) disappoints him by becoming The Caligula as President and failing to resist the Cylon occupation, he is nearly executed by his shipmates after being falsely accused of being a traitor, accidentally loses his leg to friendly fire from Anders after a standoff between Starbuck and Helo, witnesses his closest friend's death by suicide, learns that he was unknowingly complicit in the deaths of a number of people on New Caprica due to trusting the wrong person, and Adama finally "betrays" him by allying with a rebel faction of Cylons (who, despite their change in allegiances, were still responsible for the near-genocide of the human race and on a more personal level actively pushed him to his Despair Event Horizon), Gaeta finally snaps and turns against his former comrades, staging a coup d'état with Zarek.

     Dualla 

Petty Officer Anastasia 'Dee' Dualla

https://static.tvtropes.org/pmwiki/pub/images/TropeDualla_8713.jpg
Played By: Kandyse McClure

A member of Galactica's crew who first appears as a Petty Officer manning the communications panel in Galactica's CIC in the Miniseries. Gets an officer's commission sometime between Seasons 2 and 3. Tragically and suddenly dies by suicide midway through season 4 after seeing the destroyed Earth and experiencing a Despair Event Horizon.

  • All Love Is Unrequited: Downplayed. Both she and Lee do genuinely love each other, but the sad fact is that Lee still ultimately loves Kara more.
  • Ascended Extra: Gets more and more screentime as the series goes on.
  • Beta Couple: With Billy in season 1, although she ends up leaving him for Lee.
  • Beware the Nice Ones: Normally has a very sweet disposition, but doesn't even bother trying to be nice to Kara after she and Lee begin having a very obvious and borderline-public affair that humiliates both Dee and Sam. Like Lee, she also has a bit of a hidden propensity for taking mutinous or highly illegal actions when she thinks it's necessary, such as when she assists in Roslin's escape into the Fleet after the martial law declaration or helps Tigh rig the election in Roslin's favor to prevent Baltar from winning.
  • Bridge Bunnies: Her and Gaeta's place in the CIC.
  • Communications Officer: Her main job. She is later succeeded in this position by Hoshi after her death.
  • Driven to Suicide: After seeing the ruined Earth, she hits the Despair Event Horizon, and ends up dying by suicide.
  • Go Out with a Smile: An extremely dark example. A brief Hope Spot after her date with Lee implies that the two seem to be successfully reconnecting and that Dualla may be recovering from her extreme despair after witnessing the destroyed Earth, but only moments afterward Dualla chooses to end her own life while she is still experiencing what she believes is her final moment of happiness.
  • Heroic BSoD: When she's Driven to Suicide.
  • Mission Control: Along with Communications Officer, part of her job.
  • Rank Up: Has become a commissioned officer during the stay on New Caprica.
  • Red Herring: Her first name, Anastasia, means "resurrection", suggesting that she might be a Cylon and come back after her death... but she's not, and ends up getting Killed Off for Real.
  • Romantic Runner-Up: For Apollo. It becomes especially tragic during their marriage, as both characters are aware of this issue but still can't help but play into it.
  • Those Two Guys: With Gaeta in several deleted scenes.
  • Workout Fanservice: Engages in some with Apollo in the second half of Season 2 as part of their Ship Tease.
  • Your Terrorists Are Our Freedom Fighters: Discussed; both she and Tom Zarek are from Sagittaron, but she is disgusted by the support he gets and considers his actions to be unjustifiable (even if it was supposedly in the name of their planet's freedom).

     Cally 

Specialist Cally Henderson Tyrol

https://static.tvtropes.org/pmwiki/pub/images/ae2153ef_2250_40ac_b1ab_a5e3f1dc2cfd.jpeg
Played By: Nicki Clyne

"I just joined to pay for dental school."

An enlisted deckhand serving Galactica's flight wing, Cally is known for a few things: having only one name for two seasons (her full name wasn't given until her funeral!); being a Plucky Girl, and having a thing for Chief Galen Tyrol. Marries the Chief during the New Caprica year and becomes pregnant with a son, Nicholas; is then executed by Tory Foster after she (Cally) stumbles upon the secret of the Final Five.

     Doc Cottle 

Major Sherman "Doc" Cottle

https://static.tvtropes.org/pmwiki/pub/images/f2920605_ae3a_4f6b_8517_a645e2eb7ba9.jpeg
Played By: Donnelly Rhodes

A grumpy Major and the fleet's leading medic, he serves on Galactica and lectures his patients in between drags from a cigarette. His first name, Sherman, was only revealed during the series finale.

  • Ascended Extra: Was just a medic, but wound up playing a significant role in a few episodes.
  • Can't Kill You, Still Need You: A heroic variation on the trope; Cottle volunteers to take part in the Battle of the Colony in the Series Finale but Adama forbids him from coming along, assigning Cottle to safely stay behind with the Fleet because his medical expertise is too valuable to lose.
  • Cool Old Guy: One of the oldest members of Galactica's crew and no less awesome for it. Grumpy, sarcastic and one of the few people who can withstand Adama's trademark Death Glare.
  • Deadpan Snarker: Quite possibly the snarkiest character in the series.
    Cally: What if you gave me a sedative and I just slept here?
    Cottle: Oh, sure. We'll just turn my sickbay into an opium den so you can have a little snooze.
    (And in another episode:)
    Roslin: Doctor, I need your help, but it's illegal, dangerous, and a violation of your oath as an officer.
    Cottle: (Beat) You're a lousy salesman.
  • Dr. Jerk: He's grumpy and abrasive towards his patients and openly smokes on the job. He gets away with it because he's actually very good at his job and is also one of the few trained doctors left.
  • Hypocritical Humor: Lightly scolds Roslin for waiting so long to get checked for breast cancer while he's almost constantly smoking.
  • Jerk with a Heart of Gold: For all his grouchiness he's completely committed to his job and will treat anyone, human and Cylon alike. When Roslin's cancer reaches its terminal stages he's visibly upset about not being able to help her anymore and she has to tell him to resume his gruff facade. He's also absolutely revolted by the crew of the Pegasus having raped the Cylon Gina multiple times and states that Athena's near-rape by Lt. Thorne was "unforgiveable".
  • The Medic: He's the ship's resident physician and probably one of the only surviving humans with any sort of significant medical training.
  • Must Have Nicotine: Is rarely seen without a cigarette hanging in his mouth.
  • No Name Given: His first name is only given in the finale.

     Hot Dog 

Lieutenant JG Brendan Costanza (callsign: Hot Dog)

Played By: Bodie Olmos

From the same class as Kat, Hot Dog evidently flunked out of naval academy before the Destruction. He survives the entire series, eventually maturing into one of Galactica's best and most mature pilots. He's also the Real Life Apollo, as he is played by Bodie Olmos, EJO's son.

  • Ascended Extra: Originally just "new meat" but he winds up an important part of the Galactica's defense.
  • Embarrassing Nickname: He was explicitly given his callsign as a punishment.
  • Instant Expert: Presumably from offscreen training, we don't really see his skills develop.
  • New Meat: How he's introduced.
  • Took a Level in Badass: Went from New Meat to a skilled pilot.
    • In-Universe, Apollo acknowledges him taking a level when he takes his own wings and presents them to Hot Dog, telling him "I think you earned these today" because Hot Dog was still a "nugget" trainee and refused to leave Starbuck by herself when Raiders showed up during a training session.

     Anders 

Ensign Samuel T. Anders (callsign: Longshot)

https://static.tvtropes.org/pmwiki/pub/images/TropeAnders_4232.jpg
"Lighten up a little bit. It's only the end of the world."
Played By: Michael Trucco

An athlete on pre-Fall Caprica, the captain and star player of the Pyramid team Caprica Buccaneers, Anders turned his team into a resistance unit after the fall of the Colonies. He was stumbled upon by Kara Thrace and Karl Agathon while the two were trying to get off-planet, and eventually rescued late in Season 2. He becomes a major figure in the resistance on New Caprica, not to mention Starbuck's husband. Oh, and he's a Cylon and one of the Final Five.

  • Academic Athlete: Anders is a star Pyramid player and like the rest of the Final Five, was a research scientist in his original life on Earth. And could also sing and play guitar, apparently.
  • Ascended Extra: Joins the main cast after being rescued from Caprica.
  • Ascend to a Higher Plane of Existence: "See you on the other side". Although this may simply refer to the afterlife — he's heading to his stellar grave, and addressing a dead woman...
  • Deadpan Snarker: Not his most defining characteristic, but he can hold his own. No wonder he gets along so well with Starbuck.
  • Death of Personality: After having a bullet removed from his brain, he's left seemingly brain-dead, and when the Cylons link him up to Galactica, he's left as a Hybrid who only occasionally shows flashes of memory and personality, such as when he addresses Galen by name in the Grand Finale and says goodbye to Starbuck.
  • Emergency Transformation: He's turned into Galactica's Hybrid in an attempt to save him.
  • Game of Nerds: Or the in-universe equivalent, Pyramid. Notably, in the final episode, Anders — arguably the least cerebral of the Cylons in his Colonial identity — is revealed in a flashback to have a passion for the geometry and mathematics involved in sports.
  • Genre Savvy: He manages to survive several months on Caprica along with his Pyramid team by copying guerilla tactics he saw in movies. He's also smart enough to realize that the movies aren't real life and that movie tactics can only carry him and his team so far, so he seeks out professional advice from Starbuck at the first opportunity.
  • Glowing Mechanical Eyes: His eye flashes red in response to a scan by a Cylon Raider in the Season 4 premiere.
  • Handicapped Badass: He's hit in the back of the head by a stray bullet during Gaeta's mutiny and needs to have brain surgery. Afterwards, he's left brain-dead to all appearances, and later hooked up to Galactica in the manner of a Cylon Hybrid to jumpstart him but never regains the use of his legs and remains connected to the ship.
  • Living Emotional Crutch: Takes over some of this role from Lee toward Kara after their marriage, although it never reaches the same level of codependency.
  • Meaningful Name: "Anders" means "man" (or "android").
  • Mr. Fanservice: His sex scenes with Starbuck often make the effort to show just as much of his Heroic Build as they do Starbuck's. In-Universe, Leoben refers to him as a "face selling magazines", and a flashback in the Grand Finale shows him being interviewed in a bathtub.
  • Mysterious Middle Initial: It's never revealed what the "T." in "Samuel T. Anders" stands for.
  • Heroic Suicide: He flies the Fleet into the Sun both so he can see Starbuck again in the afterlife and prevent the Vicious Cycle plaguing man and Cylon from repeating itself on the new Earth.
  • Real Life Writes the Plot: Trucco suffered a major spinal injury in a car crash, resulting in Anders's bullet to the head and spending the rest of the series in either a hospital bed or a Hybrid tub. Trucco went on to make a near-miraculous full recovery and so Anders was able to become an Action Hero again in the post-series movie The Plan.
  • Really 700 Years Old: Like the other members of the Final Five, he is technically well over two millennia old.
  • Satellite Love Interest: Started out as this trope (his initial importance to the plot was solely as the love interest Starbuck left behind on Caprica), but eventually grew beyond it.
  • Ship Tease: In the last two episodes of Season 3, with Starbuck being dead at the time, he's teased with fellow trainee Viper pilot Diana Seelix, and then sleeps with Tory Foster. What with Starbuck coming back to life and all the craziness around the Final Five, neither ultimately goes anywhere. Seelix in fact becomes a mutineer and a Woman Scorned.
  • Spaceship Girl: A Gender Flipped example - in order to save his life, he gets linked up to Galactica via a tub and datastream in the same way that a Hybrid is connected to a Cylon Basestar.
  • Spanner in the Works:
    • His interactions with the Caprica iteration of John Cavil incited noteworthy Character Development within that version of Cavil, which would help reveal the other Cavil acting as a spy in the Fleet.
    • Him serving as a fighter pilot in "He That Believeth in Me" leads to a Raider scanning him and identifying him as a Cylon. This leads to all of the Raiders breaking off and letting the Colonials escape, saving everyone's lives. Furthermore, when Cavil tries to account for this issue by lobotomizing the Raiders, it sparks an Enemy Civil War that leads to the downfall of the loyalist Cylons and the discovery of Earth-2 by the humans and rebel Cylons.
  • Took a Level in Badass: He becomes a rather decent Viper pilot after joining the military following Starbuck's death. After enlisting, he has the rank of ensign and the callsign "Longshot".
  • Walking Spoiler: He's one of the Final Five and a Cylon.
  • You Are What You Hate: Along with Saul Tigh, he's probably the most reluctant of the Final Five to initially accept actually being a Cylon, which is understandable given that he was a leader in the anti-Cylon resistance on both Caprica and New Caprica and saw many of his friends killed by them up close.

     Kat 

Lieutenant JG Louanne 'Kat' Katraine

https://static.tvtropes.org/pmwiki/pub/images/b711ad85_6817_4c26_b6a1_5f28a2bbe0a4.jpeg
"When you come back after a successful run, lemme tell you, it is better than a great meal, better than hitting the jackpot, it's better than SEX!"
Played By: Luciana Carro

A "nugget" introduced early in the first season, she soon starts competing with Starbuck for the title of The Ace and even achieves the position of Commander Air Group (previously held by such luminaries as Apollo, Starbuck and Helo) before a Heroic Sacrifice in Season 3.

  • The Ace: Played with; she may well surpass Starbuck as the most naturally talented pilot in the fleet (especially considering that Starbuck had full military training, whereas Kat just had a few hastily arranged and barely-structured lessons), but her personality issues keep getting in the way of her being an outright Ace.
  • Ascended Extra: Starts out as just another nugget. Grows into CAG before dying.
  • The Atoner: She dies to make up for her Dark and Troubled Past.
  • Better Than Sex: She considers a successful combat operation to be better than sex.
  • Butt-Monkey: Repeatedly almost dies horribly, which eventually causes her to turn to drugs. This results in her losing her position as CAG, and then she dies horribly of radiation poisoning.
  • Dark and Troubled Past: Was a smuggler before the Fall of the Colonies. Decided to turn her life around by signing up for the military under an assumed name.
  • Dead Person Impersonation: Her real name is Sasha, but she's been masquerading as a dead girl, as her own identity (part of a smuggling crew that may or may not have unknowingly helped the Cylons infiltrate the colonies) wouldn't have gotten her into the military, to say the least.
  • A Death in the Limelight: "The Passage" gives her a lot of focus and explores her backstory, and she dies in a Heroic Sacrifice at the end.
  • Driven to Suicide: It's implied that her Heroic Sacrifice was partially motivated by this, since her past was about to be exposed and she had already been exposed to fatal doses of radiation.
  • Heroic Sacrifice: She continues on a mission well after she's exposed herself to a fatal amount of radiation, refusing to allow any other ships to be lost under her command.
  • Impersonation-Exclusive Character: We never get to see the real Louanne Katraine.
  • Jerkass Has a Point: Kat is childish, abrasive, and petty, but she's also the only person to consistently call Starbuck out on her bullshit.
  • Mauve Shirt: She appears the most out of the non-main character Viper pilots, and gets a lot of characterization.
  • New Meat: How she's introduced.
  • Took a Level in Jerkass: After getting addicted to drugs, Kat becomes a Jerkass who berates and harasses pretty much everyone she sees.
  • Rank Up: Reaches Captain before her Heroic Sacrifice.
  • Vitriolic Best Buds: She and Starbuck have a very complicated relationship, which alternates between being a mentor-protege relationship and mutual hatred mixed with respect. They eventually settle their differences while Kat dies of radiation poisoning.

     Crashdown 

Lieutenant JG Alex Quartarro (Callsign: Crashdown)

https://static.tvtropes.org/pmwiki/pub/images/a362b962_622c_4a60_93b2_3c93cda46d9b.jpeg
Played By: Sam Witwer

Boomer's copilot after Helo is left on Caprica. He is later a member of the Raptor crew stranded on Kobol, and takes charge of the group.

  • Guy in Back: Introduced as Boomer's new ECO after Helo stays behind on Caprica. She's not very happy about the arrangement but eventually warms up to him. After her failed suicide attempt Crashdown takes over as pilot for the Kobol mission.
  • Hero of Another Story: He's described as a surviving pilot from another, destroyed, Battlestar.
  • Killed Off for Real: Baltar shoots him to stop him from killing Cally.
  • Leader Wannabe: As the only officer present, he takes charge of the surviving members of the landing party on Kobol. He does his best, but he quickly proves to be incompetent and winds up getting most of the group killed, and his failures and the stress he's under ultimately causes him to snap.
  • Never Speak Ill of the Dead: Gaius reports to Apollo that Crashdown died leading the charge against the Cylons. Tyrol, Cally and Seelix don't dispute his version of events, suggesting they believe in this trope.
  • The Peter Principle: As an ECO (his actual job 99% of the time) he's competent enough, but he's a wretchedly poor command officer, struggles to think on his feet, and doesn't have the skillset or experience to know when to refrain from exercising his authority. This leads to multiple unnecessary deaths when he ends up in charge on Kobol, including his own.
  • Sanity Slippage: Crashdown starts to lose it after he gets two of his group killed, culminating in him trying to murder Cally.
  • Unfriendly Fire: Baltar shoots him In the Back.

     Nowart 

Sergeant Allan Nowart

Played By: Colin Corrigan

A Marine aboard Galactica serving as Sergeant of the Guard, who took over the role after the previous Sergeant was killed during the events of "Rapture". Nowart goes on to have an increasingly important background role, being present at several key encounters during the fourth season.

  • Ascended Extra: Shows up as a Marine with no dialogue in "The Woman King". By the time the show gets to the fourth season, he has more speaking lines, and by the end of the series, he's graduated to being Lee's second-in-command during the assault on the Colony.
  • The Atoner: He decides to take part in the assault on the Colony in the series finale, seemingly out of guilt for having supported the attempted mutiny on Galactica.
  • Contrived Coincidence: Despite never appearing before the episode "The Woman King", Nowart is suddenly present at several key moments in the series, including Helo's confrontation with Dr. Robert, protecting Romo Lampkin during Gaius Baltar's trial, acting as a guard for Kara after she seemingly comes back from the dead, escorting Adama and Tigh to the brig during the mutiny, and eventually, acting as Lee's second-in-command during the assault on the Colony.
  • Doom Magnet: The Marines Nowart partners with are often on the receiving end of violent incidents. As Sergeant of the Guard, his first Marine partner, Cheadle, ends up taking the brunt of an explosion meant for Lampkin. A few days later, he and his partner are incapacitated by Kara as she escapes from Colonial custody. Following that, his Marine companion during the mutiny is shot dead by Tigh, and he's very nearly killed by Kara after Adama tells him to leave.
  • Escort Mission: His primary role appears to be acting as an escort/guard for key characters, as he (along with a fellow Marine, who ultimately makes a Heroic Sacrifice) are assigned to guard Romo Lampkin prior to Baltar's trial in the third season. At the beginning of the fourth season, he's ordered to escort Kara through Galactica. Later, he's ordered by Gaeta to escort Adama and Tigh to the brig, though he eventually flips and aids them in their escape.
  • Field Promotion: Despite being imprisoned for his role in the mutiny, he supports Adama's mission to assault the Colony and rescue Hera. As a result, he becomes Lee's second-in-command in the ground team, and aids him in breaching the Colony and giving status updates on the area.
  • Honor Before Reason: Played with. He initially supports Zarek and Gaeta's mutiny out of the belief that the Colonial Fleet shouldn't be allied with the Cylons, but becomes increasingly uneasy with his decision. When he's ordered to escort Adama and Tigh to the brig, he flips on his fellow guard, telling them that he still supports the actual command crew, and eventually, lets them go.
  • My God, What Have I Done?: Although he initially supports Gaeta and Zarek's mutiny, he's not fully committed to it, and lets Adama and Tigh go after he'd been ordered to escort them to a brig. He flees to parts unknown after Kara fires some warning shots at him (though a Deleted Scene shows him returning to the CIC to tell Gaeta and Gage what happened}.
  • Remember the New Guy?: He shows up for the first time midway through the third season, having been a member of Galactica's Marines all through the series but never glimpsed beforehand.
  • Rewarded as a Traitor Deserves: Narrowly averted. Starbuck attempts to shoot him in the back as he flees from Adama and Tigh during the mutiny, only for the latter two to stop her, saying he's not worth it.
  • Spanner in the Works: Were it not for him deciding to flip and aid Adama and Tigh, Gaeta and Zarek's initial plan for the mutiny would have gone off without a hitch. Instead, they are able to buy enough time to get several key members of the fleet off Galactica and to the Basestar.
  • Those Two Guys: With fellow Marine Henry Cheadle. That is, until Cheadle sacrifices himself to save Romo Lampkin's life.
  • What Happened to the Mouse?: It's left unclear if Nowart survived the Centurion boarding attempt as Cavil and the other enemy Cylons assaulted Galactica in the series finale, as he isn't seen during or after the boarding action.

     Venner 

Corporal Venner

Played By: Mike Shields

A Colonial Marine placed in charge of guarding Roslin when she was arrested following the military coup, though he quickly proves to be sympathetic to her and provides her aid whenever possible.

     Socinus 

Specialist Alonzo Socinus

Played By: Alonso Oyarzun

A deckhand who works with Chief Tyrol.

  • Mercy Kill: Despite attempts to save him, his injuries from the Raptor crash prove too severe and Tyrol is forced to euthanize him with a drug overdose.
  • The Scapegoat: He willingly takes the blame for a security breach that Tyrol would have been blamed for and lets himself be arrested. Tyrol is shocked by this and tries to confess to Adama, but Adama lets Socinus' false confession stand because regardless of his guilt or lack thereof, he still lied under oath, and Tyrol's experience and expertise make him impossible to easily replace.
  • Secret-Keeper: For Tyrol and Boomer.
  • Surprisingly Realistic Outcome: Despite being arrested for claiming responsibility for the security breach that allows Doral to perform a suicide bombing, he gets released and serves as part of the the scout mission on Kobol because Galactica has so little crew to spare.

     Prosna 

Specialist Prosna

Played By: Michael Eklund

A deckhand who works with Tyrol and Cally.

  • Red Shirt: Dies during the pod venting in the Miniseries.
  • Cruel and Unusual Death: He burns alive during the pod venting.
  • Dead Star Walking: He's played by Michael Eklund, a well-known character actor, and he winds up being one of the first of Galactica's crew to bite the dust.
  • Heroic Sacrifice: It's implied he was trapped in the port flight pod during the pod venting was because he remains behind to help with the evacuation.
  • Mauve Shirt: He is prominently featured during the Miniseries, but he winds up dying before it ends.
  • Nice Guy: A kindhearted fellow who stays up late to wrap a gift for Adama.

     Sergeant Hadrian 

Sergeant Hadrian

Played By: Jill Teed

Galactica's Master-At-Arms, who is in charge of maintaining internal security.

  • Inspector Javert: During the investigation of Doral's suicide attack, she goes out of her way to harass anyone she suspects, and she winds up turning the whole thing into a witch hunt.
  • Jerkass: A major hardass who goes out of her way to harass anyone she suspects of wrongdoing, whether they actually did it or not.
    • Jerkass Has a Point: The people she comes down hard on are lying to her about something, though, and she did tell Adama that her tribunal would require full authority and access, before he withdrew it when she started inconveniencing him. While there's no wide conspiracy of human Cylon collaborators, her two chief suspects, Boomer and Chief Tyrol, are respectively an actual Cylon sleeper agent and someone emotionally compromised enough to cover up damning evidence that the former is a sleeper agent.
  • What Happened to the Mouse?: The last we see of her in person, Adama remands her to her quarters after he gets fed up with her causing a witch hunt. “Valley of Darkness” has Tigh mention she is leading one of the military squads hunting a Cylon that had boarded Galactica, so it's possible she kept her position.

     Racetrack 

Lieutenant JG Margaret Edmondson (callsign: Racetrack)

Played By: Leah Cairns

A cynical, somewhat nihilistic Raptor pilot.

  • The Atoner: She's among the prisoners who volunteer for the Final Battle with the people they'd fought against.
  • The Cynic: She has a very bitter outlook on life.
  • Deadfoot Leadfoot: Armed her nukes just before she was killed. Her hand slips post-mortem and accidentally fires them.
  • Dying Moment of Awesome: She wants to go out taking as many Cylon with her as she can. She gets to do it, albeit posthumously, via a nuclear bomb she had pre-armed.
  • Fantastic Racism: She really hates Cylons, even more than Tigh.
  • The Fatalist: She is not unjustifiably under the belief she'll die on a mission. She eventually dies during the mission to rescue Hera from the Cylons.
  • Guy in Back: Is introduced as a temporary ECO for Boomer after Helo is left on Caprica and Crashdown takes lead on the trip to Kobol. When Boomer is arrested Racetrack gets a promotion to the pilot's seat. During the third season she spends some time as Athena's ECO as the exodus from New Caprica means there's now more pilots than available ships.
  • Heel–Face Revolving Door: Which side she is one fluctuates from moment to moment. Mostly she serves loyally on Galactica, but she joins Roslin's side during the fleet schism and later she joins Gaeta's mutiny.
  • Locked Out of the Loop: During the mutiny it's implied that she's unaware of the murderous actions Zarek is engaging in as part of the plan.
  • Mauve Shirt: Out of the Raptor pilots, she appears the most and gets the most characterization. She even manages to survive all the way up to the finale.

     Skulls 

Lieutenant Hamish McCall (callsign:Skulls)

Played By: Colin Lawrence

A Raptor pilot who accidentally found Kobol alongside Racetrack.

  • Bald of Awesome: A very competent pilot, and he doesn’t have a speck of hair on his head.
  • Guy in Back: Serves this role for Racetrack.
  • Lack of Empathy: He doesn't give a damn when Zarek bludgeons Laird to death with a wrench.
  • Mauve Shirt: He doesn't get that much characterization, but he manages to survive all the way until the series finale.
  • Red Shirt: He dies when a piece of debris crashes into his ship.

     Chuckles 

Lieutenant JG Donald Perry (callsign:Chuckles)

Played By: Terry Chen

An experienced pilot conscripted to be a Viper pilot.

  • Red Shirt: Killed during a raid on the Cylon refinery when anti-aircraft bullets pierce his Viper.

     Jammer 

Specialist James 'Jammer' Lyman

Played By: Dominic Zamprogna

A deckhand who becomes a prominent supporting character during the New Caprica Arc.

  • Irony: Early in the series, he's quick to suspect his crewmates of being Cylons when their ability to pass as human becomes public knowledge. On New Caprica, he becomes a willing collaborator with the Cylons himself.
  • Les Collaborateurs: Joins the New Caprica Police, effectively turning on the rest of the humans and siding with the Cylons.
  • Military Moonshiner: He's introduced making homemade whiskey with Socinus and Cally.
  • Pet the Dog: He does save Cally's life when she's a prisoner.
  • Secret-Keeper: One of several crewmen covering up Boomer and Tyrol's relationship.
  • Thrown Out the Airlock: He's executed this way by The Circle once they uncover his collaboration with the Cylons.

     Duck 

Lieutenant JG Tucker Clellan (callsign:Duck)

Played By: Christian Tessier

A Viper pilot who serves as a minor Mauve Shirt in the first half of the series. He later retires during the New Caprica arc, planning to settle down with his girlfriend Nora Farmer.

  • Despair Event Horizon: Crosses it after Nora is killed by a Cylon attack, and agrees to become a suicide bomber because he has nothing else to live for.

     Kelly 

Captain Aaron Kelly

Played By: Ty Olsson

The Landing Signal Officer for Galactica who oversses all landing procedures on the ship. Possibly third-in-command after Adama and Tigh, depending on where the CAG fits into the chain of command.

  • Commuting on a Bus: Despite his high rank he only appears a handful of times throughout the series, most prominently in the Miniseries. His official job means he's presumably down at the landing bay whenever we don't see him. When he does make an appearance in CIC it's usually because there's a major crisis, such as at the beginning of season two when Adama is in critical condition after being shot.
  • My God, What Have I Done?: Initially sides with Zarek and Gaeta during the mutiny and leads the squad tasked with bringing Adama and Tigh in. Being ordered to escort Adama to his execution is apparently too far as he breaks down in Memorial Hallway rather than take part. He then defects to join Lee and the others in rescuing Adama in retaking the ship.
  • What Happened to the Mouse?: His last appearance is in "Blood on the Scales" and he isn't mentioned in the finale so his fate is unknown.

    Barolay 

Jean Barolay

Played By: Alison Down

A member of Anders's resistance. She later joins up with the military as a civilian volunteer.

  • Irony: She died without ever learning that her long-time friend, team captain and resistance leader Sam Anders was a Cylon.
  • Karmic Death: She's killed by a Six whom she had traumatized by drowning her back on New Caprica.
  • La Résistance: Was a member of the resistance on Caprica and later of the New Caprica version.

    Figurski 

Specialist Anthony Figurski

Played By: Don Thompson

One of the deckhand serving under Tyrol.

    Cheadle 

Henry Cheadle

Played By: Chris Boyd

A Marine.

    Seelix 

Ensign Diana Seelix (callsign: Hardball)

Played By: Jennifer Halley

A deckhand serving under Tyrol. She later becomes a Viper pilot in Season 3.

  • Doomed Hurt Guy: Subverted. She's severely injured while stranded on New Caprica, but she's able to survive in spite of how dire things look for her.
  • Mauve Shirt: She gets some characterization and is one of the longest lasting deckhands outside of Tyrol, frequently recurring throughout the show.
  • Put on a Bus: She's imprisoned along with the rest of the mutineers. Unlike Racetrack and Skulls, she doesn't come Back for the Finale.
  • Rank Up: In Season 3, she goes from a deckhand to a trainee pilot, thus ranking up from non-commissioned officer to ensign.
  • Romantic Runner-Up: After Starbuck dies and Seelix and Anders have both become rookie pilots, they seem rather close playing Pyramid together on the deck and she's visibly upset to see that he's slept with Tory.
  • Woman Scorned: Referenced by her when she and Connor capture Anders during Gaeta's mutiny.

    Tarn 

Specialist Tarn

Played By: Warren Christie

A deckhand serving under Tyrol.

  • Mauve Shirt: He appears in the last two episodes of the first season before being killed off early on in Season 2.
  • Multiple Gunshot Death: He's shot multiple times by a Centurion on New Kobol.

    Matthias 

Gunnery Sgt. Erin Matthias

Played By: Eileen Pedde

A high-ranking Marine.

  • Dropped a Bridge on Him: She randomly gets killed by a damaged Cylon Raider exploding. Starbuck later notes that her death was completely pointless; it wasn’t even a trap, it was just a stupid accident.

Civilian Fleet

     Tory Foster 

Tory Foster

https://static.tvtropes.org/pmwiki/pub/images/TropeFoster_9713.jpg
Played By: Rekha Sharma

Special Aide to the President, replacing the deceased Billy Keikaya. Snarky and gorgeous, Foster is primarily used as a Bit Character for the first two seasons so that the audience can get someone to bounce off of Roslin. However, in a massive twist, she turns out to be a Cylon and one of the Final Five. Amusingly, Word of God has outright admitted that this decision was precisely because she hadn't yet had much Character Development up until that point. It also created the interesting situation that all three Number Twos in the show are (arguably) Double Agents.

  • A God Am I: Her reaction to finding out her true nature is roughly along these lines.
  • Ascended Extra: Started out just as an aide, wound up being one of the Final Five.
  • Establishing Character Moment: Her attempt to rig the presidential vote in favor of Roslin proves her to be a much more Machiavellian character than her predecessor.
  • Face–Heel Turn: Pulls one when she murders Cally in cold blood, and begins to act increasingly contemptuous of the humans around her, most notably by taking D'Anna's side when she's trying to extort the Galactica crew. She's the only one of the Final Five to do so, and the only one who is killed by another character (Anders also dies, but of flying himself and the derelict Fleet into the sun after Earth is found).
  • Go Mad from the Revelation: It's all but stated that she slowly lost her mind after realizing that her entire life was a lie due to being a Cylon.
  • Hates Being Alone: According to Ellen in the extended version of Daybreak.
  • Ms. Fanservice: Serves as one by virtue of being played by Rekha Sharma.
  • Neck Snap: Dies this way in the finale after Tyrol finds out that she murdered Cally and lied about it.
  • Number Two: For President Roslin after the death of Billy Keikeya prior to her Face–Heel Turn.
  • Really 700 Years Old: Like the other members of the Final Five, she is technically well over two millennia old.
  • Reincarnation Romance: Inverted. The original Tory and Galen were madly in love, but their Colonial versions are both too distracted by other people and concerns to even notice each other. When they find out, they just snicker, and it's further inverted in the hardest way possible. In "Crossroads", just before they find out they're Cylons, Tory has been having sex with Sam, whom she's not noted to have been in a relationship with before, rather than Galen.
  • Sexy Secretary: Tory is Roslin's personal assistant and quite attractive. When she sets out to get information out of Baltar, he says to Head-Baltar that she's a "sexy lady".
  • The Snark Knight: Her demeanor is professional, eye-rolling and unimpressed, at least before learning she's a Cylon.
  • Token Evil Teammate: Of the "modern" iterations of the Final Five, she is the only one to betray humanity to the Cylons.
  • Unwitting Instigator of Doom: Her murdering Cally indirectly ends up dooming the entire Cylon race to extinction, as Tyrol finds out at the worst possible moment and kills her in revenge, causing knowledge of resurrection technology to be irrevocably lost.
  • Walking Spoiler: She's one of the Final Five and a Cylon.

     Billy Keikeya 

Billy Keikeya

Played By: Paul Campbell

Personal aide to Secretary of Education Laura Roslin, he spends one and a half seasons flirting with Dualla before being killed in a stand-off and, eventually, replaced by Tory Foster.

     Ellen Tigh 

Ellen Tigh

https://static.tvtropes.org/pmwiki/pub/images/Ellen_Tigh_1323.jpg
"You don't wanna frak with me, Bill. Try to remember that."
Played By: Kate Vernon

Tigh's wife, who miraculously survived the Fall of the Twelve Colonies. She's manipulative, vain and kind of a bitch, a Lady Macbeth with her husband as object-of-control, and Adama notes that she and Saul just tend to make each other worse. During the New Caprica occupation, she seduces a One to free her husband from imprisonment, and then is forced to betray a crucial meeting. In response, Saul poisons her. This makes it even freakier that she turns out to be one of the Final Five and a Cylon.

  • Aw, Look! They Really Do Love Each Other: Ellen and Saul very much have this dynamic.
  • Character Development: After remembering she's a Cylon, Ellen becomes far smarter, calmer and more collected along with developing a much deeper level of empathy for other people.
  • Dirty Old Woman: The point of pretty much all of her introductory episode, "Tigh Me Up, Tigh Me Down". Lee's face when she pinches his ass is priceless. Even after she returns with her full Cylon memories in "Deadlock", she jokes that "Experience is the best teacher - apart from me."
  • Jerk with a Heart of Gold: Evolves into one post-Character Development.
  • Lady Drunk: She's rarely seen without a drink in hand, which doesn't help her already grating personality.
  • Lady Macbeth: She brings out the absolute worst in Saul, encouraging him to indulge in vices and make all manner of terrible decisions. There's a reason fandom calls her "Lady McTigh".
  • Meaningful Name: "Ellen" means "light" or "torch." She was the first member of the Final Five to come up with their Fling a Light into the Future plan.
  • The Millstone: She's very, very good at making bad situations worse.
  • Poisonous Friend: As Adama commented once, she tends to bring out Saul's worst and most self-destructive instincts. It's most noticeable when Saul takes command of the fleet early in Season 2 and makes a string of bad decisions, several of which were inspired by her.
    • It seems to work both ways: Ellen seems to be a lot more ambitious and manipulative around Saul, even after becoming the Team Mom.
  • Really 700 Years Old: Like the other members of the Final Five, she is technically well over two millennia old.
  • Really Gets Around: invoked To the point of groping Lee when she's at dinner with Tigh.
  • Reincarnation Romance: She and Saul were married originally too, and somehow found each other again after Cavil wiped their memories.
  • Thicker Than Water: Amazingly, she still loves John even after every horrible thing he did because he's her son and offers him redemption, which he refuses out of spite.
  • Took a Level in Kindness: Subverted. After regaining her memories, she becomes far kinder, more mature, and wiser... only to immediately revert back to her old ways the second she gets back on Galactica.
  • Walking Spoiler: Like her husband, she's one of the Final Five and a Cylon.

     Tom Zarek 

Tom Zarek

https://static.tvtropes.org/pmwiki/pub/images/tom_zarek_profile.jpg
Played By: Richard Hatch

Introduced as an inmate on the prison ship Astral Queen, Zarek was jailed for acts of terrorism. He sees himself as a Well-Intentioned Extremist working for the common man; whether that's true or not, he's definitely good at politics. After inhabiting the Heel–Face Revolving Door for several seasons, he settles on the bad-guy side, leading a mutiny against Roslin and Adama.

  • Ambiguously Evil: For all the bad things he's done, he's often not... necessarily wrong in what he says or wants.
  • The Charmer: He's undeniably charming and charismatic. He has no need to rule his men with fear, as they genuinely adore him.
  • Death Seeker: It's suggested by Lee in his first appearance that Zarek is one since he thinks that this would make him an Inspirational Martyr.
  • Even Evil Has Standards: Though the 'evil' part is kind of tenuous, especially in this series. Zarek immediately cuts off all contact with Phelan after he learns of the latter's child prostitution ring.
  • Face–Heel Turn: Unquestionably becomes a villain in the final season when he sparks a bloody mutiny in the Fleet.
  • Face Death with Dignity: He goes to his execution with quiet stoicism.
  • Fatal Flaw: Pride. Zarek is incredibly arrogant and often thinks of himself and his goals as being above the scrutiny of others, even if those goals endanger the survival and destiny of humanity.
  • Hypocrite:
    • Gives Roslin and Adama shit for circumventing democracy. What does he do when the Quorum refuses to support Zarek and Gaeta's mutiny? Have them all executed.
    • Generally speaking, Zarek often argues for the protection of democracy... and most of these methods he proposes for doing so are coincidentally actions that would support tyranny if he ever got in charge.
  • Jerk with a Heart of Jerk: He may have his sympathetic moments and constantly champion for the preservation of democracy among the surviving Colonials, but at the end of the day, he's ultimately only in this for the power and desires to be a tyrant over the remnants of humanity so as to sate his own ego.
  • Jumping Off the Slippery Slope: After spending most of the series gradually slipping from a Well-Intentioned Extremist no different morally from Roslin, he crosses the line into power-mad tyranny during his and Gaeta's mutiny when he kills the Quorum of Twelve for refusing to support the coup.
  • Karmic Death: Considering the above, and what he planned to do to Bill if he caught him, he gets his just desserts when his mutiny is defeated and Bill has him executed by firing squad.
  • Kick the Dog: Has the Quorum of Twelve executed by firing squad when they refuse to support his mutiny.
  • Know When to Fold 'Em:
    • During the search for the Tomb of Athena. His right-hand wants to keep pressing on with their plan to arrange an "accident" for Apollo, but he's smart enough to realise his window of opportunity has closed and abandons that plan. For now.
    • Doesn't run for reelection because he knows he can't rule without the support of the military. However when elements of the military become disillusioned with the Adama/Roslin administration, he takes the opportunity to launch a Military Coup.
  • Meaningful Name: "Zarek" is a Polish derivation of Belshazzar, son of Babylonian monarch Nebuchadnezzar. Nebuchadnezzar is perhaps best remembered for the Biblical story of the feast in which God's hand wrote a warning on the wall that the monarchy would soon be overturned; Zarek seeks to overturn the Colonial government.
  • Motive Decay: In part from the natural stress of the surviving Colonials' flight from the Cylons' genocide, he gradually becomes less and less of a Well-Intentioned Extremist until he becomes a ruthless wannabe tyrant in the final season.
  • Mythology Gag: Zarek is played by Richard Hatch, who played Apollo in the original series. Zarek spends much of his time antagonizing the present Apollo, and in his first episode, he lectured Apollo on the meaning of his callsign.
  • Not-So-Well-Intentioned Extremist: On the surface, Zarek may call himself a "freedom fighter" and paint himself as a patriotic rebel fighting for the rights of democracy against Adama and Roslin's dual dictatorship, but at the end of the day, he still shoved the Quorum of Twelve in front of a firing squad when they refused to rubber-stamp his unlawful mutiny. In fact, it's after him killing the Quorum of Twelve that Gaeta realizes that Zarek is really in his mutiny only for the power and isn't a genuinely Well-Intentioned Extremist like he is.
  • Off Screen Villainy: When the series starts he's imprisoned for terrorism, and he's suspected of involvement in abuse of office, political manipulation, and conspiracy to commit murder. As Roslin herself ends up committing most of these crimes, the writers had to give Zarek some ruthless acts during his grab for power just to restore the balance (and even these are entirely Pragmatic Villainy).
  • OOC Is Serious Business: When President Roslin tells him she is going to give Baltar a fair and public trial, Zarek's initial reaction is to completely freak out and advise that, against all precedent and his own personal convictions, martial law be declared for the duration. Roslin seems genuinely perturbed by just how out of character this is for him.
  • Principles Zealot: Truly believes that he is working to improve the lot of the common man, and genuinely believes in the principles of freedom and democracy...and is willing to do absolutely, positively anything in pursuit of those beliefs, no matter how underhanded, morally questionable, dishonest, or actively detrimental to the survival of humanity it might be.
  • Slowly Slipping Into Evil: Zarek gets gradually more ruthless over the course of the series, all the while slowly abandoning his principles in the pursuit of power. By the time of the mutiny, all Zarek cares about is ruling over humanity to sate his own ego.
  • The Starscream: When he was Vice-President.
  • Villain Has a Point:
    • In his first episode, Zarek makes the more or less valid argument that the fleet is treating him and the other prisoners aboard The Astral Queen as an expendable labor force, and that even though they are coming to them for help, the prisoners are still not allowed to chart their own course and everyone is acting like absolutely nothing has changed. Apollo ultimately decides Zarek has a point and ends up meeting him halfway.
    • Later on in the series, he repeatedly draws attention to the fact that Roslin and Adama (who later become romantically involved) tend to make unilateral decisions for the fleet between them and that they adamantly resist just about any oversight or checks on their authority. Adama dissolves a board of inquiry he himself created when it begins to question his own decisions and loyalties, and Roslin tries to rig her reelection campaign against Baltar when she's afraid it won't go her way.
  • Villainous Friendship: He and Meier are legitimately friends, and rather close ones at that.
  • Well-Intentioned Extremist: At first, anyway.
  • Your Terrorists Are Our Freedom Fighters: His supporters view him as a hero fighting for Sagittaron liberation. His critics view him as a destructive terrorist. Debates and the occasional fistfight have broken out over this issue. Dee, who's also from Sagittaron, is one of his biggest critics as she believes that freedom doesn't justify his violent actions.
    Billy: He's a freedom fighter. He's a prisoner of conscience.
    Dee: He's a butcher.

"Everybody has demons. Them, Baltar, you, me. Even the machines. The law is just a way of exorcising them."
Played By: Mark Sheppard

An eccentric, self-absorbed and attention-hungry lawyer who takes up the unwanted job of being Gaius Baltar's attorney during his (Baltar's) farcical trial. Trained as a lawyer by Joseph Adama, William Adama's father (and Lee's grandfather).

  • Amoral Attorney: Downplayed - he's ethically questionable and has penchants for deception and psychological manipulation, but he's not a horrible man, and is dedicated to the preservation of the colonies above all else.
  • Bunny-Ears Lawyer: Literally a lawyer, and tremendously skilled. The man got Gaius off in what was supposed to be a show trial. He's also very quirky.
  • Deadpan Snarker: He's played by Mark Sheppard, of course he's snarky.
  • Honor Before Reason: He'll do his job to the best of his ability regardless of who he's representing.
  • Jerk with a Heart of Gold: He's a pretty sleazy guy, but his heart is in the right place. During Gaeta and Zarek's coup, he proves helpful to the heroes and aids Kara in getting an injured Sam to the medical bay.
  • Manipulative Bastard: He is excellent at manipulating people, which is one of the reasons he's so good at his job.
  • Sticky Fingers: He's a kelptomaniac who lifts items off the other characters to sate his impulse. This ends up being plot relevant in his first episode as he lifts an item that tips Lee off as to who planted the bombs on the Raptors.
  • Sunglasses at Night: A character quirk is that he wears sunglasses everywhere all the time, no exceptions unless it plays into one of his gambits.

     Meier 

Meier

Played By: James Remar

Tom Zarek's righthand man during the fleet schism.

     Elosha 

Elosha

Played By: Lorena Gale

A priest who serves as a spiritual advisor for Roslin.

  • Good Shepherd: She is a priest who does her best to advise Roslin on matters related to the prophecies of the Sacred Scrolls.
  • Killed Off for Real: Blown up by a land mine in "Home".
  • Magical Negro:invoked Falls into this trope, with it being especially glaring when she appears later on in Roslin's vision and advises her to love again. Interestingly, Word of God via the podcasts reveal the initial person giving the message in the visions was going to Billy, but the actor was unavailable and the role altered with much of the dialog remaining the same, with the producer stating it actually fits Elosha better and her skin color being black was just a coincidence in terms of how her character was written.
  • Sacrificial Lion: She's a major recurring character killed during "Home" to show how high the stakes are.

     President Adar 

President Richard Adar

Played By: Colm Feore

The President of the Colonies prior to Roslin who was killed during the Cylon attack at the beginning of the series.

  • Early Installment Weirdness: The first few episodes imply that he was actually a Reasonable Authority Figure, and it's only in later episodes that him being a Corrupt Politician is made more obvious.
  • Jerkass: Flashbacks show that he was an incompetent president who would rather kill innocent people than make a compromise and look "weak".
  • Know When to Fold 'Em: He desperately offered an unconditional surrender to the Cylons after their first strike during the Fall. They ignored his offer.
  • President Evil: He was willing to use military force to stop a peaceful protest by teachers, which would no doubt cause casualties, and got angry with Roslin for compromising with them because he thought it makes him look weak.

    Boxey 

Boxey

Played By: Connor Widdows

A young boy who survives the Cylons' initial attack and is evacuated to Galactica by Boomer.

  • Chuck Cunningham Syndrome: He's a minor presence throughout the Miniseries, makes a single appearance in the first season and then disappears completely. Several other scenes with him were shot during the first season but all were cut except for his brief appearance assisting Starbuck with a light-hearted air group briefing in "Bastille Day".
  • Demoted to Extra: Compared to his original series counterpart this version of Boxey has a significantly smaller role. The original plan for him to form a family unit with Boomer and Tyrol was dropped after the decision to make Boomer a Cylon sleeper. The writers then tried to reposition him as The Artful Dodger but ultimately decided there wasn't enough time to develop the idea.
  • Orphan's Ordeal: His father is implied to be the Armistice officer killed in the opening scene of the Miniseries and his mother died during the attack on Caprica. He seems to get over it pretty quickly as he replies to Tigh asking where his mother is with a sarcastic "Dead".

    Sesha Abinell 

Sesha Abinell

Played By: Dana Delany

A terrorist and conspiracy theorist convinced that Cylons are controlling the Colonial Military.

  • Conspiracy Theorist: She's convinced the Cylons are still manipulating the military, which is not helped at all by her knowledge of Athena's existence.
  • Freudian Excuse: Her descent into radicalism was caused by the death of her husband during a Cylon attack.
  • Freudian Excuse Is No Excuse: That said, it's literally everyone has lost someone to the Cylons, so it's really no excuse.

    Phelan 

Phelan

Played By: Bill Duke
"It's hard to find the moral high ground when we're all standing in the mud."

The head of the fleet's black market.

  • Faux Affably Evil: He acts polite and civil to Lee, even when admitting that he runs a child prostitution ring.
  • Soft-Spoken Sadist: He rarely raises his voice, which does nothing to contrast from what a monster he is.

    Emily Kowalski 

Emily Kowalski

Played By: Nana Visitor

A terminal cancer patient who Roslin befriends.

  • Deadpan Snarker: She's very sardonic and witty, even making snarky remarks to Roslin, the President.
  • Freak Out: She has a full-blown meltdown when Roslin turns off her radio, which was playing Baltar's religious speeches. She later apologizes, saying that it's the only thing giving her hope.
  • We Hardly Knew Ye: Though to be fair, she gets a ton of characterization in her one episode.

    Gerard 

Dr. Gerard

Played By: John Hodgman

A civilian brain surgeon.

  • Dr. Jerk: He's rather uncaring about Anders's brain surgery and shows zero empathy to him or Starbuck, seeming more vaguely amused by the situation than anything.
  • Jerkass: He's smug, aloof, and unempathetic.

Battlestar Pegasus

     Admiral Cain 

Rear Admiral Helena Cain

https://static.tvtropes.org/pmwiki/pub/images/TropeCain_577.jpg
"Sometimes terrible things have to be done."
Played By: Michelle Forbes

Captain of the only other (known) battlestar to survive the massacre of the Twelve Colonies, Cain adopted a much more ruthless attitude towards survival.

  • Adaptational Villainy: Whereas her counterpart in the 1978 series tended to make questionable decisions but was ultimately a good person at heart, any redeeming qualities have long-since ceased to apply to this version.
  • Ax-Crazy: When it comes to Cylons.
  • Bad Boss: Knowing humanity is on its last legs, she'll do whatever she has to, including killing civilians or crew members that disagree with her.
  • Defiant to the End: She curses her killer right before she's executed.
  • Face Death with Dignity: No whimpering, no tears, no pleading, just a dull stare of hatred.
  • Evil Counterpart: She's one to Adama. Pegasus had its own civilian fleet once, but it's not with them anymore...
  • Four-Star Badass: She's earned her title, no doubt.
  • Freudian Excuse: She witnessed her younger sister and father being abducted by the Cylons in the last days of the First War, adding to her hatred of them.
  • Gender Flip: In the 1978 series her character was played by Lloyd Bridges.
  • General Ripper: To contrast Adama's A Father to His Men persona.
  • Hanging Judge: She's obsessed with revenge. Anybody who doesn't toe the line or serve an immediately-valuable purpose gets a bullet through the head.
  • He Who Fights Monsters: Some of the things done by her or on her orders are arguably more monstrous than things the Cylons have done.
  • Hypocrite: Promises her officers that she will not seek revenge against the Cylons, or sacrifice lives needlessly. When push comes to shove, she does exactly that with absolutely zero conflict or hesitation.
    • She also hates it whenever others abuse or over exert their authority, but she does this multiple times and ignores that Thorne had done so as well when he attacked Athena in her cell without permission or supervision from the Galactica crew.
  • I Did What I Had to Do: Has no remorse over the awful things she's done.
  • I Lied: Soon after her return, when the Galactica crew notes that she's actually above Adama in the chain of command, she promises to be a Reasonable Authority Figure and refrain from encroaching on his rightful command of the Galactica fleet. She breaks this promise almost immediately, pressuring Adama into subordinating his pilots by integrating them into a joint force with hers, and then leaps off the edge entirely by ordering the execution of two of his crew members who, in the process of saving their Cylon companion from being raped, killed the would-be-rapist, who was acting on her orders. Notably, she never admits to deceiving Adama, and insists she's being completely fair and just in her decisions even when everyone knows better.
  • Insane Admiral: Not fully insane, just... devoted.
  • It's All About Me: Kind of implied, as she treats everyone around her like they are expendable in her mad pursuit of revenge against the Cylons. She throws away her men’s lives and the lives of civilians for petty vengeance, and is okay with murdering herself anyone who is not one-hundred percent obedient to her.
  • Jerkass Has a Point: Oh so many...
    • Ironically, most of the things she does have a point about are things she is even worse about.
  • Karmic Death: Meets her end at the hands of the Cylon she ordered to be extensively tortured, getting a bullet between the eyes, the same as she gave to her friend Colonel Belzen.
  • Kick the Dog: Hardass that she is, her longtime friendship with her XO Colonel Belzen serves to humanize her. She is apparently close friends with his family, as well. So when she shoots him in the head for disobeying her (senseless) orders, it establishes that most of the good left in her is gone.
  • Knight Templar: Even Athena, a valued member of the crew who has probably done as much as any one person other than Adama, is just another Cylon to her.
  • Name of Cain: The first tip-off she's not all sunshine and rainbows.
  • Names to Run Away from Really Fast: See Name of Cain.
  • Never My Fault: She's big on this. She executes her XO personally for "insubordination". (See: for refusing an irrational order that contradicted Cain's earlier promise that she would not throw away their lives seeking revenge).
  • "Not So Different" Remark: Adama points out that he might have made the same decisions as Cain had Roslin, Lee, and the civilians not been there to keep him in check.
  • Pet the Dog: Both her and Adama come to separate decisions to have each other assassinated. (Although in Cain's instance, she includes his entire command staff) Adama ultimately decides not to go through with it, which is in character for him. Cain also decides not to do it, which is pretty shocking.
  • Psycho Lesbian: According to "Razor." That her lover was a Cylon is part of her fierce stance.
  • Sanity Slippage: Her XO notes she's gone through this, becoming more ruthless and cruel.
  • Smug Snake: She firmly believes she's right and will let anyone know.
  • Statuesque Stunner: Comes with being played by 5'9" Michelle Forbes.
  • Straight Gay: If it weren't for her relationship with Gina, you'd never know.
  • Tragic Villain: It is rather sad what happened to this woman in her life.
  • The Unfettered: Won't let anything stop her quest, not pesky morals or human lives.
  • Villainous Crush: She seems to take an interest in Kara, and has her transferred from the Galactica to the Pegasus. Thankfully, Cain isn't around long enough to act further on it.
  • Well-Intentioned Extremist: She'll ensure humanity's survival at any cost, even if it means crossing all sorts of horrible lines.
  • What You Are in the Dark: Is given the opportunity to terminate Adama and his entire command. She doesn't do it, and nobody in the series ever ends up learning about this, as both Cain and Fisk are dead not two episodes afterwards.

     Hoshi 

Lieutenant Louis Hoshi

Played By: Brad Dryborough

Frst appearing as a Pegasus CIC officer, Hoshi continues to serve in the background throughout the rest of the series, eventually being promoted to Admiral as the ranking officer left with the civilian fleet when Galactica jumps away to fight the show's Final Battle. Was revealed to be gay for Gaeta late in the series.

  • Ascended Extra: Don't expect to remember his face in the show itself, but in the show's webisodes he was featured as Gaeta's love interest.
  • Communications Officer: His initial role.
  • Field Promotion: To Admiral in the Grand Finale when Adama and most of the senior crew are on the rescue mission.
  • Straight Gay: As seems to be standard in the Colonies. We get no hint of his sexuality before the reveal of his relationship with Gaeta.
  • Token Good Teammate: One of the few members of the Pegasus crew who isn't a Jerkass, which might be why he was chosen as interim Admiral in the finale.

     Fisk 

Colonel Jack Fisk

Played By: Graham Beckel
"Civilians wouldn't be civilians without bitching about something."

  • Dirty Cop: It takes him all of five seconds to start working with Phelan.
  • Dirty Coward: After Cain summarily executes Belzen for refusing to carry out an order that will likely get most of their fighter pilots killed, the hastily-promoted Fisk carries out said order with only minor hesitation. Somewhat justifiable, as Cain would otherwise have probably just executed her way through her bridge crew until she found someone willing to carry out her order, with the Cylons free to carry on shooting up the Pegasus in the meantime.
  • Dropped a Bridge on Him: He gets killed by a random hitman at the beginning of "Black Market" in an area (his quarters) that should have been totally secure.
  • Jerkass: An unpleasant, corrupt dick who refuses to take responsibility for his own actions.
  • Just Following Orders: He takes no responsibility for the awful things the Pegasus' crew has done, though it's clear from his talk with Tigh that he's troubled by them nonetheless.
  • A Lighter Shade of Grey: Only in the sense that he's just corrupt and cowardly rather than bloodthirsty and insane (like Cain), or morally depraved (like Thorne).
  • Pet the Dog: Saves Helo and Chief Tyrol from a beat down at the hands of some Pegasus crewmembers after the two of them inadvertently end up killing Lieutenant Thorne. He says he does it more for "the sake of the uniform" and that he still does not like them since Thorne apparently saved his life along with at least one other Pegasus crewmember.
  • Punch-Clock Villain: Of sorts. See A Lighter Shade of Grey, above.
  • Razor Floss: [[spoiler:Phelan has him garroted for asking for too much money.]

     Kendra Shaw 

Lieutenant Kendra Shaw

  • The Atoner: No matter how she tries to rationalize it, she knows she's damned for executing Laird's wife.
  • Break the Cutie: Some of it is self-inflicted, but still ...
  • Evil Counterpart: Well, maybe not quite evil, but she's a counterpart to Starbuck.
  • Heroic Sacrifice: Goes out blowing up an entire Cylon basestar with a nuclear bomb.
  • Heroic BSoD: Immediately after shooting Mrs. Laird, she stares at the residual smoke drifting from her sidearm's muzzle. The look on her face, like she's praying that it's all just a bad dream but knows better, is gut-wrenching.
  • New Meat: The Cylon attack kicked off within half an hour of her reporting to the Pegasus.
  • Hero of Another Story: That story is depicted in Razor.
  • Redemption Equals Death: She goes out blowing up an entire Cylon baseship.
  • Remember the New Guy?: Razor establishes that she's been part of the Pegasus crew since the Fall of the Colonies, but since she was created for the telemovie there was no mention of her during the second season.
  • Screw the Rules, I Have Connections!: Cain accuses Shaw of having friends of her late mother (a Quorum of Twelve member) get her a prestigious posting on the Pegasus, although it's unclear if this is true.

     Thorne 

Lieutenant Alastair Thorne

Played By: Fulvio Cecere

  • Asshole Victim: Played With. No one in the original Galactica crew remotely faults Tyrol and Helo for accidentally killing him, but the people in Pegasus are a different story, as some of them actively relished and participated in Thorne's gang-rape of the Cylons (and it was their own bragging that tipped off Helo and Tyrol to begin with). In fact, some of the Pegasus engineers keep bringing up his death as late as Gaeta's coup arc, where they promise to avenge him.
  • Bald of Evil: He’s bald, and an unrepentant Cylon rapist.
  • Fantastic Racism: Cylons aren't people to him.
  • Pet the Dog: Apparently saved Fisk and one other Pegasus crew member's lives, though this happened entirely offscreen.
  • Rape Is a Special Kind of Evil: His job description apparently includes raping as a form of torture.

     Garner 

Commander Barry Garner

Played By: John Heard

Originally the chief engineer of the Pegasus, he was promoted commander after the deaths of Cain and Fisk.

  • Closest Thing We Got: Admiral Adama reasoning for the nomination: "He's the best they got".
  • Heroic Sacrifice: He dies by suffocation in space vacuum after repairing a coolant leak in the FTL drive to save the Pegasus and allow the ship and her crew to escape a battle with the Cylons.
  • Jerkass: He's paranoid and incompetent, and repeatedly harasses Starbuck for not agreeing with him all the time,
    • Jerk with a Heart of Gold: That said, he is by no means a bad person, and eventually realizes his own failings and gives his life to save the ship and crew.
  • The Paranoiac: He believes that Adama and the fleet leadership are trying to set him up, and in return does his best to make life hell for any former Galactica crew onboard.
  • The Peter Principle: A tragic example. The man is a very good engineer who can repair an FTL drive in the middle of battle, but he is no starship commander. He himself seems to realize this once he orders the Pegasus into a trap, as he relinquishes command to Lee, who knows more about tactics and strategy than he does, and goes down to engineering to help there.
    Lee Adama: He was used to working with machines. Command is about people.
  • Redemption Equals Death: After spending most of his time as commander being a paranoid Jerkass, he sacrifices himself to repair the FTL drive so the Pegasus can escape.
  • Tragic Keepsake: His watch, left in CIC when he went below decks to the engine room to solve a critical breakdown in battle. Apollo keeps it and wears it afterwards as a reminder.
  • Unexpected Successor: Originally the chief engineer of the Pegasus, it is suggested that he was one of the only high-ranking officers left on board after Cain, Belzen and Fisk's deaths.

     Belzen 

Colonel Jurgen Belzen

Played By: Steve Bacic

  • Boom, Headshot!: Turns out Admiral Cain doesn't care for alternatives.
  • Death by Origin Story: Fisk wasn't kidding about that Noodle Incident.
  • Nice Guy: A friendly and compassionate officer.
  • Number Two: To Cain, until she shot him for refusing to follow orders.
  • Only Sane Man: Tries to stop Admiral Cain from pointlessly sacrificing the lives of her crew and air wing when the Cylon communications relay they're attacking turns out to be a staging grounds far more heavily defended than they anticipated. He failed to recognize that she wasn't suffering a Heroic BSoD, she had gone straight Ax-Crazy. See above for the result.
  • Posthumous Character: Already dead by the time the Pegasus first appears, his only screentime is in flashbacks during Razor.

     Laird 

Peter Laird

Played By: Vincent Gale

A civilian forced by Admiral Cain to serve as part of the crew of the Pegasus.

  • Dark and Troubled Past: He was forced into serving on the Pegasus and had his family killed by Shaw.
  • Dropped a Bridge on Him: In spite of being one of the most prominent Pegasus crew members and surviving for longer than the other prominent Pegasus crew, he dies abruptly when Zarek bludgeons him over the head with a wrench during his attempted coup.
  • Mauve Shirt: Laird pops up repeatedly throughout the series, and manages to outlive most of the other prominent Pegasus characters in spite of being a more minor character than them.
  • Press-Ganged: He was a civilian aeronautical engineer before being forced into service as the Pegasus Crew Chief.

Cylons

     In General 
A race of sentient machines created by humans so as to help make life easier, but who then rebelled against and tried to exterminate their masters. Originally just consisting of the purely robotic Cylon Centurions, the end of the First Cylon War resulted in the Centurions meeting with the "Final Five," a group of humanoid Cylons who are the only survivors of a Cylon generation pre-dating the Colonies' Centurions. The following collaboration between the original Centurions and the Final Five resulted in the creation of eight new humanoid models, each of which has many copies (some of which have received more Character Development than others). The last five humanoid Cylons (a.k.a. the aforementioned Final Five) are later revealed to be major players in the human fleet.

  • Adaptation Origin Connection: In the original series, the Cylons were created by an extinct alien race (also named the Cylons), versus being created by humanity here.
  • A.I. Is a Crapshoot: The initial Cylons rebelled and fought against humanity. Even the more-mechanical Cylon centurions are liable to rebel against their Artificial Human masters unless kept in check.
  • Artificial Human: Until the massacre, no one knew humanoid Cylons existed.
  • Born-Again Immortality: As long as they're within range of a Resurrection Ship, no Cylon can truly be killed as they'll just be downloaded into another body.
  • Cloning Blues: Mostly the Final Five.
  • Cyborg: Most if not all Cylons are cyborgs. The Raiders are almost entirely organic on the inside, and the human-forms are ambiguous. On the one hand, they are extremely difficult to tell from humans. On the other, Sharon once accomplished something useful by cutting her hand open and jamming a fiber-optic cable inside. In a later episode it is stated that the human-form Cylons have some sort of organic optical data port in their hands, which is how they control and receive data from the basestars. Presumably Sharon was inserting the fiber so that she could make a good connection to the Galactica's less advanced hardware. On a Basestar, they just stick their hands in the literal datastream. The Centurions are in fact the only ones who are entirely mechanical.
  • Deader Than Dead: Humanoid Cylons can be Killed Off for Real by either being "boxed" (having their software downloaded and abandoned in cold storage followed by the genetic sequence for their artificial bodies being "broken" so no new bodies can be created for them) or being killed when far enough away from a Resurrection Ship. And after the Colonials and rebel Cylons blow up the Resurrection Hub in Season 4, this applies to every Cylon from now on without the Final Five's intervention. This also applies to any Raider, though there doesn't seem to be any need for them being "boxed."
  • Duplicate Divergence: The model lines start out interchangeable from one another, but by the end of the series some of the Sixes and Eights have developed individual personalities and even names.
  • Dying Race: The Cylons cannot reproduce and can only make new variations of the current seven models.
  • Enemy Civil War: While inter-factional conflicts have been breaking out within the Cylons as early as Season 2, it's not until Season 4 that the Cylons actually break into outright civil war.
  • Eye Lights Out: Badly damaged Centurions and Raiders do this whenever they die.
  • Heel–Face Turn: After the Cylon Civil War breaks out, the Twos, Sixes and Eights collectively side with the Colonials over Cavil's forces, and settle with the humans on Earth in the Grand Finale.
  • Hypocrite:
  • Mechanical Evolution: The Cylons Centurions are completely and obviously mechanical, the humanoid models are seemingly human Cyborgs that are essentially impossible to distinguish from "real" humans, and the Raiders are outwardly mechanical but actually contain genetically engineered innards.
  • Mechanistic Alien Culture: Not a straight example, but played with - The Cylon Civil War happens to a large degree because Six's and Cavil's factions disagree about whether their society of Artificial Humans should explore their humanity (Six's faction) or embrace their nature as machines and "be the best machines the universe has ever seen" (Cavil's faction). Cavil is a real hypocrite about this, though, and most of his behavior is due to the fact that he hates having been given human form when his creators could have just as easily designed him as a mighty god-like A.I..
  • Me's a Crowd: While they don't exactly share memories, each model does share an overall personality. That being said, each Cylon model appears to share a general "background" memory (with situations like Athena recalling her two years as a pilot on Galactica and even fondly remembering Boomer's relationship with Tyrol despite Athena herself technically having never been aboard the Galactica physically until the second half of Season 2) and common personality traits (according to Cavil, all Number Eights suffer from Chronic Backstabbing Disorder).
  • Mind Hive: A fascinatingly confusing example can be seen with the humanoid Cylons. Overall, each model consists of numerous different individuals that can develop their own unique personalities given enough time. This results in lots of weird situations where Cylons who look completely identical to each other physically showcase completely opposite outlooks, like the repentant Caprica-Cavil and genocidal Galactica-Cavil in The Plan just being one example among many.
  • Nature Versus Nurture: While each model has a core personality, their separate experiences can make copies very distinct.
  • No Delays for the Wicked: Subverted with The Plan, with it being shown that they ultimately suffered from as many logistical, tactical and strategic issues as the Colonials did.
  • Organic Technology: Most of their more advanced tech consists of this.
  • Robots Enslaving Robots: The humanoid models enslaved their robotic Centurion predecessors.
  • Ridiculously Human Robots: The humanoid Cylons are more or less impossible to identify.
  • Scary Dogmatic Aliens: More Scary Dogmatic Robots, but the effect is more or less still the same.
  • You Are Number 6: Mostly referred to by their model number.

     Number Ones 

Brother John Cavil/Number One

https://static.tvtropes.org/pmwiki/pub/images/TropeCavil_7391.jpg
"Delusional machines! What's the universe gonna come up with next?"
Played By: Dean Stockwell

Initially introduced as a priest from whom Tyrol seeks spiritual guidance, Cavil is revealed (practically on the same day) to be a Cylon. While the Cylons had previously run on a direct democracy, Cavil begins to take over as the series progresses, and his slight personality flaws go center-stage....

  • A Day in the Limelight: The Plan has him as the Villain Protagonist.
  • Affably Evil: Mostly Faux Affably Evil, but since there are more than one of him, it gets a little tricky.
  • Agonizing Stomach Wound: During the New Caprica arc, one Cavil is shot in the stomach and left to bleed out by a resistance member. Cavil winds up slitting his wrists with a bullet, and later complains to Baltar about it.
  • Ancient Keeper: In Season 3, he is the barrier to D'Anna seeking knowledge of the Final Five. In Season 4, he claims to the other Cylons that their original programmers must have had a good reason for making the Five secret and violating that programming would be disastrous. He's lying through his teeth. The Final Five are themselves the original programmers; he knows perfectly well who each of them is, and is the one who reprogrammed his siblings to forget them.
  • Antagonistic Offspring: To the Final Five, who (especially Saul and Ellen) are considered the "parents" of the other humanoid Cylons. He's made it his mission in life to not only reject their philosophy but prove them wrong in the most painful way possible.
  • Asshole Victim: No tears are shed for him when he gets Killed Off for Real in "Daybreak."
  • Ate His Gun: He kills himself this way in the finale.
  • Bad Habits: They tend to adopt priestly identities when infiltrating Colonial society.
  • Being Human Sucks: Or at least that's what Cavil believes. Much of what he does is him lashing out because he believes himself afflicted with human weaknesses. See his Motive Rant below.
  • Better to Die than Be Killed: In the Grand Finale, as his loyalists are being slaughtered and he's surrounded by the Colonials and rebel Cylons, both of whom would either imprison or kill him, during the climactic shoot-out in the CIC, he chooses to cop take the easy way out and eat his gun.
  • Big Bad: Revealed in both Season 4 and "The Plan" to be more or less behind everything in the plot since the series began: The Cylon attack on the colonies, the concealment of the Final Five, the lobotomy of the Raiders (prompting the Cylon Civil War), everything.
  • Breakout Villain: In large part thanks to Dean Stockwell's excellent performance, Cavil quickly went from just another Cylon model to being the Big Bad of the entire series and the Greater-Scope Villain behind practically everything.
  • Character Development: In the movie The Plan. Especially the hat-wearing copy on Caprica, which is the only one of his line in the entire series to show mercy and realize that what the Cylons did was wrong. It's a shame that he was "boxed" by the other Cavils and is never seen again.
  • Characterization Marches On: In his first appearances, he seemed to be merely the one model that was programmed to be atheistic and point out "Hello, we're machines!" every so often in order to, as Ron Moore put it, "keep the Cylons honest", and even appeared to be one of the least enthusiastic about the genocide. Later episodes made him the Big Bad.
  • The Chessmaster: They've been controlling and setting everything in the series up so as to torment his creators.
  • Classic Villain: Wrath and Pride.
  • Cool Old Guy: If you can ignore the genocide and sadism, he's pretty snarky. The person he was based on (Ellen's father), however, was apparently a kindhearted old man who nurtured his daughter's education and research. It's a bit sad that John's personality turned out to be the polar opposite.
  • Deadpan Snarker: As good as Baltar, to the point where he's one of the most sarcastic people in the whole series.
    Cavil: (presents Doral with a vest strapped with C4) They call this a "suicide vest." But I think that undersells all the homicide that goes along with it... Don't you?
  • Disproportionate Retribution: The Cylons' genocide against humanity was organized by him in order to enact "revenge" upon Ellen and the rest of the Final Five for creating him in an imperfect body. He also planted his five Cylon parents as amnesiac humans in the Colonies to give them front row seats to the ensuing genocide, and subsequently played cruel mindgames with them for several months so as to torment them even more. Then he rapes his mother and rips out his father's eye. "Petulant" doesn't begin to cover it.
  • Do Not Call Me "Paul": He really hates his given name, John (after Ellen's father).
  • Evil All Along: His introduction in Season 2 portrayed him quite ambiguously, as he acts rather benignly while infiltrating the fleet, and after being exposed, offers no resistance to his arrest and claims to regret participating in the genocide of the human race. Season 3 however, clearly shows what a nasty piece of work he truly is, as he tortures and mutilates Saul Tigh, and uses him to blackmail and sexually abuse his wife, Ellen, and in general simply derails the relationship between humans and Cylons before convincing the occupying Cylons to just murder all dissidents. Season 4 further reveals him to be a dishonest manipulator who's responsible for the entire genocide and war, as he's the one who convinced the other Cylon models that all humans needed to be exterminated, and then tried to cover up the identities of the Final Five because it would get in the way of his own petty revenge scheme against them.
  • Evil Is Petty: The Fall of the Twelve Colonies, which he helped spearhead, is ultimately a ridiculously circuitous and childish attempt at proving to his creators, the Final Five, that Humans Are the Real Monsters since he's angry over them not having crafted the "superior machine" he wanted to be.
  • Evil Old Folks: The oldest looking of the Cylons and by far the evilest.
  • Faux Affably Evil: As the series goes on, his polite and amusing façade falls away, and his true face as a ruthless and sociopathic monster becomes increasingly apparent.
  • For the Evulz: His primary motive is jealousy and revenge, but he notes several times that he's doing it for no other reason than cruelty. His mother even calls him out as a sadist at one point.
  • Guttural Growler: He speaks with a gravelly voice.
  • Hate Sink: For as entertaining as he is, it's made abundantly clear he's not meant to be liked. He's self-righteous, cruel, petty, hypocritical, sadistic, childish, egotistical, and that's not even getting into any of the massive amount of utterly disgusting things he's done, which includes torturing his own father and cutting out his eye, while forcing his mother to have sex with him just so he won't kill him just to be an asshole.
  • Hypocrite: At one point, Cavil advocates the destruction of humanity for its sins in enslaving the robotic Centurions. However, he did just the same to the modern Centurion model.
  • It's All About Me: Cavil is even more egotistical and selfish than Baltar.
  • Jerkass: Cavil has no positive or redeeming traits whatsoever. He's just a massive dick who only cares about himself.
  • Kavorka Man: Manages to get in with Ellen, Boomer, and Tough Six. Boomer even goes back to him after having had sex with Helo. This is despite having the appearance of a man in his sixties and being completely homicidal. Presumably, as the oldest and most respected of the Cylons, Power Is Sexy played some part in his younger siblings being fine shacking up with him, while Ellen was simply blackmailed.
  • Kick the Dog: Killed his "brother" Daniel, wiped the memories of the Final Five, organized the genocide of the vast majority of the human race, raped his own mother, tore his father's eye out, starting killing off half of his own people when they began questioning the house of cards he'd built... Really, it'd be harder to find examples of Cavil not doing something utterly reprehensible.
  • Killed Off for Real: He finally dies for good in "Daybreak" when he chooses to shoot himself after it becomes clear he's lost.
  • Knight Templar: Cavil is totally convinced that everything he's done is justifiable because humans are terrible and deserve to die. It's worth noting that this seems to be more him rationalizing that he's basically just throwing a massive temper tantrum than anything genuine.
  • Large Ham: Not usually, but he slides into this during his Motive Rant about just how much he loathes his human body.
  • Manipulative Bastard: Not just the humans, but they manipulate other Cylons as well.
  • Meaningful Name: "Cavil" is derived from the Old English word ca-feld, "field where jackdaws or crows are seen", which serves as a subtle allusion to his murderous sadism. A Cavil is also an irrelevant quip in conversation.
  • Morality Pet: The orphaned boy (also named John) in The Plan, to Fleet Cavil. Subverted in that Cavil kills him when he realizes this trope is in effect.
  • Motive Rant: He really doesn't like his human form.
    Cavil: In all your travels, have you ever seen a star supernova? No? Well, I have. I saw a star explode and send out the building blocks of the universe; other stars, other planets, and, eventually, other life. A supernova: creation itself. I was there, I wanted to see it, and be part of the moment. And you know how I perceived one of the most glorious events in the universe? With these ridiculous gelatinous orbs in my skull! I want to see gamma rays! I want to hear X-rays! And I, I wanna smell dark matter! Do you see the absurdity of what I am? I can't even express these things properly, because I have to conceptualize complex ideas in this stupid limiting spoken language! But I know I wanna reach out with something other than these prehensile paws, and feel the solar wind of a supernova flowing over me. I'm a machine, and I can know much more. I could experience so much more, but I'm trapped in this absurd body!
    • And this is not a motive to sneer at, either. All Cavil wants is what every living thing, everywhere, wants: to be greater tomorrow than it is today. In fact, one could even call it a deeply human motive. Despite this, though, a great deal of resentment towards his "parents" (his "mother" in particular) colors this. He usurps control of the Cylons, ironically lobotomizes the mechanical ones (who are, in theory, closer to what he wants to be) and even seizes control of Resurrection. Maybe if he could tear himself away from his spiteful efforts to commit genocide against his creators and humanity, he could have worked out a technological means to become what he claimed he wanted to be.
  • No Transhumanism Allowed: Deconstructed. The fact that he wasn't able to be a "superior" machine because the Final Five believed that the Cylons should be as close to humanity as possible, since that's what they thought God wanted them to be like, is his primary motive for causing the near-extinction of humanity and psychologically tormenting the Final Five.
  • Nice Hat: Often wore one earlier on, as seen in his picture above.
  • Oedipus Complex: He rapes his mother after gouging his father's eye out.
  • Omnicidal Maniac: Still, it's all in how he chose to express that desire for greatness.
  • Parental Incest: invoked He knowingly has sex with Ellen Tigh, his "mother" for all intents and purposes (his creator, certainly). Oh, and he apparently resembles her father. Why yes, it is just as revolting as it sounds. Though at least she spent their time together as an amnesiac...
  • Pinocchio Syndrome: As is evident from his Motive Rant, Cavil is an Inversion. He also claims that he doesn't need to sleep anymore because he "deleted that particular subroutine." Whether this is actually true or just another part of his megalomaniacal self-delusion is unclear.
  • Pragmatic Villainy: In the Series Finale, he decides to accept the Final Five's truce by sparing Hera and letting Galactica keep her, in return for learning how Resurrection works from them. Doing so would deny him his revenge against both the Five and humanity, although he could very well try going after them later in violation of his explicit promise not to. Unfortunately for him, the deal goes south when Tyrol ends up strangling Tory, his henchmen falsely assume they're being tricked and open fire, and he and all his loyalists permanently lose their lives.
  • Psychopathic Manchild: Ultimately, Cavil's entire Rage Against the Heavens is more or less an incredibly bloody and childish tantrum directed at his creators for them having designed him like a human above the superior machine he wanted to be.
  • Psycho Prototype: As their number indicates, they were the first Cylon model to be developed, but they are also the most evil one.
  • Put Them All Out of My Misery: This is a large part of Cavil's motivation. He was created to emulate humanity, in the hope that he would come to appreciate the higher meanings of life by experiencing it in the way humans do. He rejects this notion, instead believing himself to be cursed with the limitations and failings of humanity (for all time, thanks to Cylon resurrection technology), and so he sets out to wipe the living reminder of his curse from existence and then set to work finding a way to surpass his limitations. As Ellen says, the part about trying to become a perfect machine wouldn't be so bad on its own, if he weren't determined to destroy humanity first out of pettiness.
  • Redemption Rejection: He rejects an attempt at a Cooldown Hug from his mother in "No Exit".
  • Rage Against the Heavens: Cavil is basically pissed at the entire universe because his forebears were slaves and he's a flawed humanoid, and his genocidal schemes are an extension thereof.
  • Rage Quit: In the finale, he just growls "Frak!" and eats a gun.
  • The Sociopath: Cavil cannot empathize with other people and can only see other people as pawns to be manipulated for his own benefit.
  • Scarpia Ultimatum: To his own mother.
  • Straw Hypocrite: Shamelessly exploits the religious fervor of the other Cylons to encourage their belief that replacing sinful humanity is part of God's plan for them as humanity's children, but is an atheist (or, to be more accurate, Straw Nihilist) himself. His actions become progressively more self-centered and lose even the thin veneer of any idealism as the series progresses.
  • Took a Level in Jerkass: Progressively gets worse and worse throughout the series as his Faux Affably Evil facade slips away to reveal what an utter bastard he really is.
  • Toxic Friend Influence: His influence on Boomer post-New Caprica is the primary reason behind her Face–Heel Turn.
  • Villain Protagonist: For The Plan, which follows one Cavil with Anders in the Caprican resistance and another in the Fleet.
  • White Sheep: The "Caprica-Cavil" is the only one of his entire line to actually develop a sense of empathy, even having a Heel Realization and confess that the Fall of the Twelve Colonies was a mistake. Unfortunately, he's boxed by the main Cavil as a result.
  • Younger Than They Look: Like all the new humanoid Cylons, he's only 30-40 years old, but was made in the image of Ellen's father. Being born old might have something to do with why he's so cranky.

     Number Twos 

Leoben Conoy/Number Two

https://static.tvtropes.org/pmwiki/pub/images/TropeConoy_5115.jpg
"I see the universe. I see the patterns. I see the foreshadowing that proceeds every moment, of every day."

One of the first Cylons introduced (in the pilot miniseries) and one of the first Cylons whom the Fleet finds a copy of in hiding, Leoben has something of a fixation on Starbuck, whom he is sure has a large role to play in the fates of both humans and Cylons. He's right. He goes straight back into creepy territory with his Stalker with a Crush tendencies, though he does seem to genuinely love her.

  • Affably Evil: He genuinely loves and cares for Starbuck in his own twisted way and he can be pretty pleasant company if you can ignore the psychosis.
  • Ambiguously Evil: He's right about a fair amount, and that may be for the best.
  • The Cuckoolander Was Right: Baltar's line "I may be mad. It doesn't mean I'm not right" applies just as much to Leoben.
  • Face Death with Dignity: Even when's initially scared of dying in Season 1 because he believes that he's too far away from a Resurrection Ship to be picked up and will suffer a true death, he only gives an arrogant smirk as Roslin has him Thrown Out the Airlock.
  • Genius Bruiser: He's possibly the strongest of the Cylons and remarkably crafty and cunning to boot.
  • Heel–Face Turn: The Twos as a whole join Natalie Faust, the other Sixes, and the Eights on the "good" side in the Cylon Civil War.
  • Immortal Life Is Cheap: Was murdered every night by Starbuck only to come back the next day with a new body. He never seems especially angry with Starbuck over it either.
  • Manipulative Bastard: Almost effortlessly strings Starbuck along during the New Caprica occupation.
  • Non-Action Guy: In comparison to the Sixes and Eights when their three models rebel in the Cylon Civil War. Not only do the ladies appear more in general, we see a gaggle of Pilot Sixes and Pilot Eights working with the Colonials, but no Pilot Twos.
  • Not Afraid to Die: He doesn't fear death in the slightest due to his faith.
  • The One Guy: The only male model from the Significant Seven among the rebel Cylons. With the Ones, Four and Fives on Cavil's side and the Sixes, Eights and last remaining Three on the rebel side, it's only his presence among the rebels that keeps it from being a full-on Gender War (not counting the male members of the Final Five).
  • Only Known by Their Nickname: His number isn't revealed until Season 4.
  • The Philosopher: One of the more insightful and introspective Cylons. Practically any attempt at conversation with him will be peppered with philosophical language. When the Galactica suffers a hull breach in Season 4, one of the deck crew reports to Adama that "the Leobens are calling it 'the proverbial straw.'"
  • Screw This, I'm Outta Here!: He simply walks away in barely concealed terror when he stumbles across the crashed Viper on Earth and realizes who its pilot was. He never interacts with Starbuck after that point.
  • Slasher Smile: Anytime he smiles, no matter how jovial, it inevitably ends up as this.
  • Stalker with a Crush: On Starbuck, though he got a bit better.
  • Super Strength: The only Cylon ever seen to go all "Hulk smash" on anybody. Is shown snapping cuffs with ease and turning over metal tables with one hand. The otherwise unflappable Starbuck looked ready to jump out of her skin when he showed just how strong he is. Another Two picked up Adama with one hand and stoically ignores the pain of grabbing and breaking off a steam pipe.
  • Too Kinky to Torture: None of the interrogation tactics Roslin, Adama, and Starbuck use on him have any effect, and on a few occasions he winds up enjoying it.
  • Trickster Mentor: Tries to be this to Starbuck, pushing her towards her destiny with cryptic pronouncements but also mixing lies with truth.

     Number Threes 

D'Anna Biers/Number Three

https://static.tvtropes.org/pmwiki/pub/images/TropeThree_6402.jpg
Played By: Lucy Lawless

Introduced as a rather pushy reporter doing an exposé on the Fleet (the fate of that copy is never revealed), D'Anna ends up taking center stage by becoming obsessed with discovering the identities of the "Final Five" Cylons, which (according to Cavil) are Things Man Was Not Meant to Know (or Cylons either, for that matter).

  • A God Am I: Sees herself as the Cylons' Messiah.
  • Bitch in Sheep's Clothing: She acts polite but can be just as ruthless and cold-hearted as any other Cylon.
  • Despair Event Horizon: After finding the nuked-out original Earth, she gives up and decides to stay behind and die. And as the Resurrection technology was gone, and that's the last we see of her, that's apparently what happened.
  • Driven to Suicide: Not suicide so much as letting herself die by being stranded on a barren planet.
  • Evil All Along: She was introduced as an Intrepid Reporter who causes tensions within the fleet thanks to her rather intrusive style of reporting, causing Adama to intervene by offering her the chance to film an authorized documentary with near-total access to the Galactica. Throughout the episode its left ambiguous whether or not she's really acting in good faith, until the documentary finally comes out and turns out to be a perfectly fair and respectful film that improves the fleet's morale... And then she's shown watching the film with her Cylon buddies.
  • Evil Matriarch: Not literally, but Lucy Lawless says she based her performance on this archetype.
  • Faux Affably Evil: Her friendly persona as a journalist counts as this.
  • Forbidden Fruit: Her hunger for knowledge on the Final Five, which ends with her getting "boxed" by Cavil.
  • The Gadfly: In "The Hub" she tells Laura Roslin that she's one of the Final Five and lets Roslin believe it for several seconds before admitting that she was lying.
  • Killed Off for Real: The Number Three model line is "boxed" by Cavil excluding one surviving instance, who later crosses the Despair Event Horizon and dies on the first Earth.
  • Moral Myopia: Even by Cylon standards, she's pretty bad. She constantly preaches about God and condemns humans for their brutality, conveniently forgetting that the Cylons wiped out almost fifty billion humans.
  • Narcissist: invoked Lucy Lawless described the character as "the ultimate narcissist" who sees herself as more "pure" than the other Cylons.
  • Put on a Bus: Following the events of "Eye of the Beholder" and "Rapture", her entire line is permanently boxed.
  • Straw Hypocrite: Of the religious variety. She preaches about God and respect for life while ordering mass executions of innocent civilians.
  • Well-Intentioned Extremist: Her bonding with Baltar and arc throughout Season 3 show she genuinely wishes to follow God’s will, and is willing to do whatever it takes to follow that plan.
  • Woobie, Destroyer of Worlds: She goes through a ton of suffering in Season 3, culminating in her entire line being boxed. When she comes back in Season 4, she's snapped and tries to destroy the entire fleet with a nuke before Baltar is able to talk her down.

     Number Fours 

Simon O'Neill/Number Four

https://static.tvtropes.org/pmwiki/pub/images/TropeSimon_5930.jpg
Played By: Rick Worthy

First introduced as a doctor running what turns out to be a "Farm"—a giant lab where Cylons experiment with biological reproduction—Simon is polite and well-spoken, the opposite of the Scary Black Man (Cylonism notwithstanding).

  • A Day in the Limelight: He gets more character development in The Plan than he ever did during the series.
  • Affably Evil: He's perfectly nice to Starbuck when they're in the farm.
  • Bald of Evil: Both bald and a Cylon.
  • Becoming the Mask: One of the copies in The Plan ends up genuinely falling in love with his human wife and caring for his stepdaughter.
  • Deadly Doctor: Considering he's performing research in order to figure out how to get Cylons to be able to reproduce like humans.
  • The Evil Genius: As alluded to below, they're primarily seen being utilized as scientists and researchers among Cylon society.
  • Killed Off for Real: The final Simons are all gunned down during the climactic shoot-out at the end of "Daybreak".
  • Punch-Clock Villain: Unlike Cavil and Doral's open contempt for humanity, the Simons as a whole seem to be going along with the others' agenda because they're interested in the science of restoring resurrection and reproduction.
  • Non-Action Guy: They are almost never seen on the front lines unlike Doral.
  • Omnidisciplinary Scientist: He generally shows up whenever a Cylon character is needed to be seen doing something "scientific."
  • Redemption Equals Death: The copy in The Plan commits suicide to protect his wife and stepdaughter from Cavil.
  • Scary Black Man: Subverted; the Simons are incredibly civil and friendly when talking to others and aside from genuinely unnerving moments like those involving the Cylon farms, they're more or less just Punch Clock Villains.
  • The Stoic: They tend to be among the less emotional and more professional Cylons.

     Number Fives 

Aaron Doral/Number Five

https://static.tvtropes.org/pmwiki/pub/images/TropeDoral_2610.jpg
"...parents have to die. It's the only way children can come into their own."
Played By: Matthew Bennett

Introduced as a public relations guy leading a flock of reporters through the halls of the Galactica museum, Doral was described as "Poor Man's Kevin Spacey" by Television Without Pity. He lived up to this name by proving he can totally go Ax-Crazy when he needs to.

  • Ax-Crazy: He’s generally shown to be one of the most violent Cylons, and his attacks take numerous casualties.
  • Dumb Muscle: They tend to do uninspired grunt work.
  • Demoted to Extra: He has a far more prominent and complex role in the Miniseries and Season 1. After that point, his role is more-or-less reduced to that of a simple Cylon henchman who's one of the bad guys.
  • Hoist by His Own Petard: He is blown up with the bomb he'd planned to destroy a ship with in Season 1.
  • Hypocrite: Condemns human suicide bombers, yet one of his defining moments in Season 1 has him be a suicide bomber himself.
  • I Take Offense to That Last One!: Insult his intelligence to your heart's content, but don't trash his fashion sense. What makes this difficult is that it's not really that good. In The Plan, Cavil tells the lone Doral still on the fleet that he's too recognizable since they dumped one in Ragnar on suspicion of being a Cylon. Fleet!Doral defensively says that he'd go unrecognized because his (identically styled but differently colored) jacket is completely different.
  • Jerkass: Even for a Cylon, he's not a nice guy.
  • Killed Off for Real: The final copies of Doral are gunned down during the climactic shoot-out in the CIC in the Grand Finale.
  • Misanthrope Supreme: He believes humanity got what it deserved.
  • Moral Myopia: Humans being slaughtered at random? Completely fine. Cylons being killed? Absolutely intolerable.
  • Nice Job Fixing It, Villain: In the Series Finale, he's the one who dooms Cavil and his loyalists after the Resurrection deal with the Final Five goes awry. Falsely jumping to the conclusion that he's being tricked, he opens fire on the Galactica crew, who fire back, causing everyone on his team of Cylons to be permanently killed.
  • Sharp-Dressed Man: The entire line seem to favor brightly colored jackets. The Ones berate them for this as it makes them stand out too much. The Five he's talking to protests that the first Doral's jacket was burgundy and his is teal.
  • The Sociopath: Downplayed in comparison to the Ones, but with the exception of the Caprica model tracking Helo and Athena, he typically has no concern for any loss of life, with the most emotion he expresses in response usually being mild smugness. He also shows little concern for his fellow Cylons and seems broadly driven by his own comfort and self-interest.
  • The Stoic: He's much quieter and less opinionated than other Cylons.
  • They Look Just Like Everyone Else!: His quiet personality and low-key appearance makes him ideal for infiltration missions.
  • Villain with Good Publicity: He's a PR guy, for gods sake!
  • What a Senseless Waste of Human Life: The model who along with a Six tracked Helo on Caprica was prone to some unusually empathetic and insightful thoughts concerning humans, their genocide, love, and the Cylon condition (of inability to love). At one point, he even gets his partner Six to cry while he's not looking by pointing out that Athena is getting to experience human emotion to a degree she (Six) can't even fathom. This in contrast to the model's more commonplace sociopathy and hypocrisy.

     Number Sixes 

Caprica-Six/Number Six

https://static.tvtropes.org/pmwiki/pub/images/602px_season_3___promo___amos___number_six.jpg
"Humanity's children are returning home...today."
Played By: Tricia Helfer

The Femme Fatale Cylon who seduces Baltar, she is later embraced as a hero by her people, and her voice given extra weight in their democracy—even when she suggests that the Cylons attempt peaceful co-existence with humanity. Eventually travels to Galactica along with Athena and Hera, where she spends a lot of time in the brig frakking Saul Tigh, eventually conceiving a (short-lived) child with him. She also joins Baltar in the final battle, and it's implied that the two of them, at least, get a Happily Ever After. Other significant Sixes include Shelly Godfrey, Gina Inviere, Natalie Faust, Lida and Sonja (Six is apparently the only model that uses different names for different copies).

  • The Atoner: Quickly begins to feel regret for her role in killing most of the humans.
  • Beauty Is Never Tarnished: Averted in a number of cases with Sixes such as Gina and Caprica-Six in the episode "Downloaded".
  • Canon Foreigner: She had no direct equivalent in the original series. The closest analogue would be Lucifer as Baltar's Cylon contact, but Six is a very different character.
  • Convenient Miscarriage: Convenient isn't the right word, but a pure Cylon baby would have been a game-changer.
  • Femme Fatale: Her role for Gaius.
  • Hidden Depths: Sixes aren't just sensuous but also strong-willed and intelligent, and some have a decidedly more down-to-earth appearance. And as the series goes on, they also all seem to show a surprising level of empathy.
  • Happily Ever After: The Grand Finale implies this of her and Baltar.
  • Heel Realization: She quickly realizes how horrible the Fall of the Twelve Colonies was and becomes The Atoner.
  • Hero of Another Story: Given that she has her own "Head Baltar," it's all but stated that she's been having just as many mental shenanigans going on as he is with Head Six.
  • Honey Trap: Given the model's attractiveness, it's not surprising that they're used for this.
  • In Love with the Mark: She actually fell in love with Baltar while using him to infiltrate the Colonies.
  • Mama Bear: She becomes very protective of Hera, even going so far as to snap Boomer's neck after she tried the same on the child.
  • Meaningful Name: The last name of Natalie, the Number Six Cylon who forms an Enemy Mine alliance with the Colonials, is revealed to be "Faust." Additionally, "Natalie" itself means "birthday," and Natalie ushered in a new era of Cylon-human interaction.
  • Mind Hive: Aside from Athena & Boomer among the Eights, Caprica-Six and the other Sixes are the only other Cylons to show such a significant variety in personality among a single model line.
  • Ms. Fanservice: A slinky red dress is among the least provocative of her outfits. Even one of the Recap videos on the Syfy website points out her status as this, saying (in the same monotone as the rest of the recap), "There are twelve models of humanoid Cylons. Some of them actually look like models."
  • My God, What Have I Done?: She quickly came to regret her part in the Fall of the Twelve Colonies.
  • Mystical White Hair: Caprica-Six, Head Six and most other Sixes have platinum blonde hair, and start out as an enigmatic group of characters (with Head Six never losing this quality). Several Sixes who are deliberately given a more down-to-earth look have sandy hair instead, and one has black hair.
  • Only Sane Man: In the later seasons in particular, Caprica-Six (and most other Sixes in general) comes across as one of the only Cylons to not be either an utter sociopath or religious nutjob.
  • Pregnant Hostage: During Zarek and Gaeta's coup.
  • Shout-Out: invoked According to Word of God, her model number being "Six" is meant to be an allusion to The Prisoner (1967).
  • Token Good Teammate: She's the only Cylon to express misgivings with how the New Caprica occupation is proceeding, as it was initially intended to be a peaceful coexistence. She's also the first Cylon to actually show regret over the Fall.
  • Trauma Conga Line: In many ways, she goes through just as hellish an ordeal as Baltar does after being "welcomed back" into Cylon society following the completion of her mission.

Gina Inviere/Number Six

https://static.tvtropes.org/pmwiki/pub/images/ginapromo2.jpg
Played By: Tricia Helfer

Another Number Six model that stowed away on the Battlestar Pegasus. She was Helena Cain's most trusted confidante and lover before she was discovered to be a Cylon, leading to her being extensively tortured by the crew for information. After being found by Gaius Baltar however, she slowly opens up.

  • Ambiguous Situation: Given that her death by nuclear explosion allowed for the Cylons to find and occupy New Caprica, it's unclear if she was actually operating (willfully or not) on behalf of the Cylons or she was just trying to kill herself while also taking the Demand Peace movement with her.
  • Ambiguously Bi: It's revealed in Razor that she had a relationship with Admiral Cain prior to being discovered as a Cylon and she also has a short-lived relationship with Gaius after he helps her escape; however, her level of willingness in both these relationships is left in doubt, as her romance with Cain happened while she was undercover and it's impossible to say how genuine her feelings were, and she is reticent around Gaius and only sleeps with him very reluctantly — potentially due to trauma from her time as a prisoner, but also possibly because she isn't interested in men and just felt a sense of gratitude or obligation toward him after he helped her.
  • Beauty Is Never Tarnished: Averted. She's been beaten and starved for months until Gaius sees her, and it shows. Tricia Helfer even lost some weight to look famished enough to convincingly portray Gina.
  • Broken Bird: Being extensively tortured for months on end would do that to a person.
  • Driven to Suicide: Ultimately kills herself by detonating a nuclear warhead, blowing up herself, Cloud Nine and several ships in the vicinity.
  • Hates Being Touched: Since the torture she underwent included sexual abuse, she recoils at any kind of physical contact.
  • Meganekko: While in disguise as a Demand Peace activist.
  • The Mole: And unlike Boomer, she was aware of her true nature.
  • Psycho Party Member: Out of the Sixes and the Cylons in general, she’s one of the few to be genuinely mentally ill, and eventually she snaps and uses a nuclear bomb Baltar gave her to perform a suicide attack.
  • Rape Is a Special Kind of Evil: Was on the receiving end of this by the Pegasus crew.
  • Tragic Villain: It's hard not to feel sorry for her given the hellish treatment she's gone through.

     Number Seven 

Daniel/Number Seven

Played By: N/A

Basically a plot device introduced late in the series to explain why the numbering on the Significant Seven jumped from Six (given to Helfer) to Eight (chosen by Park). The Daniels were artist-types and much loved by Ellen, which caused a lot of jealousy in the Ones. Eventually, Cavil took efforts to poison the entire Seven line, not only killing all extant Sevens but preventing any others of the type from ever being born.

  • Cain and Abel: Killed by their "brother" Cavil.
  • Nice Guy: He's only mentioned once, so there's not a lot to go on, but from Ellen's description he seems to have been a sweet-natured and artistic sort who wouldn't have done anything to provoke Cavil's ire, other than Ellen possibly having shown him some degree of favoritism.
  • Only One Name: Daniel.
  • Posthumous Character: No Sevens are ever actually seen, and we have no description of what they looked like.
  • Red Herring: Not intentionally, but it took personal reassurances from the producers to convince some fans that no, Daniel's sudden former existence was not indicative of any other plot twist involving him around the corner, and none of the already introduced characters were going to be revealed to be Daniel or a child of same.

     Number Eights 

Lieutenant JG Sharon Valerii/Number Eight (callsign: Boomer)

https://static.tvtropes.org/pmwiki/pub/images/TropeSeven_2252.jpg
"We need to stop being butchers."
Played By: Grace Park

Introduced as a Raptor pilot on Galactica, the Twist Ending of the pilot miniseries was that she was a Cylon. Later episodes made it clear that she didn't know she was a Cylon, and that there were programs (psychological, not software) hidden in her subconscious which caused her to be a Manchurian Agent. This culminated in her putting two rounds through Commander Adama's chest, after which she was offed by a vengeful Cally. Of course, Cylons respawn, and Boomer still had a bigger role to play....

  • Adaptation Species Change: The original series Boomer was human.
  • Adaptational Job Change: The original series Boomer was an ace Viper pilot, rather than a rookie Raptor pilot (Raptors didn't even exist in the original series).
  • Adaptational Villainy: To a degree. She is a Cylon, but a Manchurian Agent. Played straighter after she regains her memories, given her Chronic Backstabbing Disorder and working for Cavil.
  • All There in the Manual: The explanation for her Embarrassing Nickname. A Deleted Scene from the Miniseries with unfinished visual effects introduces her landing her Raptor so hard and poorly that it bounces across the flight deck, presumably making loud booming noises down in the hangar bay.
  • Chronic Backstabbing Disorder: Betrays Galactica, betrays the Cylons; Boomer even betrays the other Eights. Deconstructed (see Mood-Swinger).
  • Conveniently Unverifiable Cover Story: The "mining accident on Troy" that killed her whole family. The former Trope Namer.
  • Driven to Suicide: More than once. Late in Season 1, she begins to realize that she's a Cylon, and tries to suck-start her sidearm as a result. Thanks to her badly crippled emotional state, she botches it, managing only to blow a hole through her cheek. When ordered by Cavil (during one of her "activated" periods) to assassinate Adama, she tries to turn it into Suicide by Cop. And finally, she decides that Redemption Equals Death in how she saves Hera Agathon in the finale.
  • Fake Memories: Since "Sharon" had to have a past, she had these.
  • Gender Flip: Female, unlike the male Boomer from the original series.
  • Heel–Face Revolving Door: She has severe Chronic Backstabbing Disorder.
  • Killed Off for Real: In the Series Finale, she's gunned down by Athena and Starbuck after rescuing Hera thanks to her Chronic Backstabbing Disorder making her a liability.
  • Manchurian Agent: She seemingly had no control over herself when she shot Adama, although it's later shown that even her split personality had to reluctantly force herself to go through with it.
  • The Mole: For the Cylons.
  • Mood-Swinger: All the Eights seem to share this trait to some degree, but Boomer in particular has a tendency toward impulsivity, sudden outbursts of rage, or other inadvisable behaviors when hurt or disappointed (such as when Tyrol breaks up with her and her demeanor suddenly changes from loving to furious), which plays into why she is so prone to suddenly switching sides.
  • Ms. Fanservice: There's plenty of nude scenes of Eights.
  • Race Lift: Original series Boomer was black. Sharon is Asian.
  • Redemption Equals Death: Dies after saving Hera.
  • Related in the Adaptation:
    • In the original series, Boomer, the third-most-focused-on Viper pilot, was unrelated to Athena, who was Adama's daughter and Apollo's sister; here, they're two copies of the same Cylon model.
    • After Caprica ended, writers Kevin Murphy and Jane Espenson said that Adama's half-sister Tamara became the basis for the Number Eight model, which means Boomer is related to Adama and Apollo, without them even knowing it.
  • Sanity Slippage: Throughout Season 1 and the first half of Season 2 as she realizes she is a Cylon. She goes through one offscreen following the failure of New Caprica, and her first appearance following it has her as extraordinarily hostile and bitter towards humans.
  • Split-Personality Merge: After she dies and her memories are downloaded into a new body, she's no longer a Manchurian Agent.
  • Suicide by Cop: Boomer's Manchurian Agent psychological conditioning compelled her to shoot Commander Adama point-blank. However, in The Plan, it's revealed that even when she's "activated" and aware of what she really is, she hates what she's being compelled to do and wishes that her cover story was true, and still loves the Old Man like a surrogate father and has to be pressured into assassinating him by Brother Cavil. Turns out, she intentionally gutshoots him (nonfatally) both to subvert her Manchurian Agent programming and to get the Marines stationed in the CIC to kill her (since her suicide attempt had failed).
  • Token Evil Teammate: Boomer is the only one of the Number Eights to side with Cavil's faction during the Cylon Civil War, with the rest "jumping ship" and joining Natalie Faust's faction.
  • Token Minority: The Number Eights are the only East Asian Cylon models and Grace Park is the only East Asian actor out of the seven in the main credits.
  • Tomato in the Mirror: Boomer had no idea she was a Cylon.
  • Took a Level in Jerkass: Following the failure of New Caprica, Boomer becomes extraordinarily hostile and bitter and decides to completely embrace her nature as a a Cylon. She even threatens to murder baby Hera.
  • Trauma Conga Line: The poor woman goes through absolute hell over the course of the series.
  • Wild Card: According to Cavil, the Number Eights have a propensity for Chronic Backstabbing Disorder.

Lieutenant Sharon Agathon/Number Eight (callsign: Athena)

https://static.tvtropes.org/pmwiki/pub/images/708px_sharon_agathon.jpg
"I made a choice to wear a uniform, to be a person."
Played By: Grace Park

After the producers decided to keep Helo on as a character, their first question was what to do with him. The logical answer would be to pair him up with another Eight, whom he would think was Boomer but was actually a separate instance. This Cylon, who eventually chose the call sign "Athena" had a very specific mission: the humanoid Cylons had thus far been unable to conceive biological offspring, and their theory was that The Power of Love was what was missing. Athena's job, then, was to get Helo to fall for her (and then frak her, of course). A High-Heel–Face Turn was almost inevitable. She then became the first Cylon character to openly side with the humans.

  • Action Mom: Having Hera doesn't slow her down.
  • Adaptation Species Change: The original series Athena was human.
  • Adaptational Job Change: The original series Athena was an officer in Galactica's Core Command (the equivalent of CIC), not a combat pilot, though she could fly a shuttle.
  • Awesome Moment of Crowning: Adama commissions her as a Lieutenant just before he sends her to infiltrate New Caprica.
  • Battle Couple: With Helo.
  • Becoming the Mask: She was supposed to pretend to love Helo, but wound up doing just that. Additionally, it's implied that she originally only had a "copy" of Sharon Valerii's Fake Memories, but she slowly accepted those memories more and more as her own which led to her increasingly identifying herself as a Colonial above a Cylon.
  • Decomposite Character: The role of "Adama's child who has a relationship with Starbuck" is given to the late Zak and later Lee, while the name "Athena" is used for a completely different character.
  • Easily Forgiven: Murders Natalie Faust in a fit of paranoia because of a vision she had, just because she saw Natalie interacting with her daughter. Adama has her locked up and temporarily takes away custody of her daughter, but he goes back on that in the same episode, and later lets her out completely rather offhandedly with no consequences at all not long after, despite how this impulsive action very nearly jeopardized the Human-Cylon alliance. Later on, the allied Cylons try to take custody of Boomer so that she can be tried for her role in sparking the Cylon Civil War, but don't bother doing anything to punish Athena for murdering one of their own.
  • Happily Married: After her Heel–Face Turn, she and Helo come to have easily the most stable relationship on the show.
  • High-Heel–Face Turn: Sides with the humans due to her love for Helo.
  • Honey Trap: Was initially supposed to play this role with Helo (specifically, in order to further the Cylon goal of finding a way to conceive children), but changed her mind when she actually fell in love with him.
  • Jerk with a Heart of Gold: Blunt, cynical, sarcastic, and passionately in love with Helo, almost obsessively defensive of her daughter, & firmly dedicated to the survival of humanity.
  • Love Redeems: She sides with the Colonials due to her love for Helo.
  • Mama Bear: She'll do anything to protect Hera.
  • Meaningful Name: "Sharon" is Hebrew and means a "fertile plain," and Caprica-Sharon/Athena is the first Cylon to conceive a child with a human (or conceive at all for that matter). "Valerie" is a Latin name meaning "healthy." And on a more meta level, her name unites Hebrew and Latin terms, just as she is ultimately responsible for bringing new kinds of unity to the fleet.
  • Mood-Swinger: Downplayed example. She shares the typical Eight tendency for this, but is generally more settled and self-aware than Boomer or the background Eights, particularly after she officially joins the Fleet. Her only major example of this is when she temporarily turns her back on Helo and says she no longer cares about gaining Adama's trust after the apparent death of Hera.
  • Ms. Fanservice: Gets a rather titillating sex scene with Helo in Season 1. Also, what with being an Eight, she also has plenty of nude scenes.
  • Related in the Adaptation: In the original series, Boomer, the third-most-focused-on Viper pilot, was unrelated to Athena, who was Adama's daughter and Apollo's sister; here, they're two copies of the same Cylon model.
  • Replacement Goldfish: Lampshaded In-Universe, she essentially becomes one for Boomer after she left for the Cylons.
  • Undying Loyalty: Lacks the Heel–Face Revolving Door of her counterpart Boomer; in fact Athena's fanatical devotion to the Colonial cause may be an attempt to compensate for this weakness in the Eight model. That and the fact that the slightest indication of treachery would get her thrown out an airlock.
  • Unrelated in the Adaptation: Zigzagged. In the re-imagined series, Athena is not Adama's daughter or Apollo's sister, but Adama does play a pseudo-paternal role for her (as he does for Boomer, Dualla and Starbuck as well). However, after Caprica ended, writers Kevin Murphy and Jane Espenson said that Adama's half-sister Tamara became the basis for the Number Eight model, which means Athena is still related to Adama and Apollo, without them even knowing it.

"Sweet" Eight

Played By: Grace Park

An Eight whom Lieutenant Gaeta had a relationship with while on New Caprica. Only appears in the Face of the Enemy webisodes, but plays a pivotal role in Gaeta's season 4 character arc.

  • Becoming the Mask: Implied to have developed some kind of genuine feelings for Gaeta, given that she killed everyone else in the Raptor they were trapped on in order to save air for the two of them, including a fellow Eight. However, this doesn't stop her twisting the knife when his naïveté and (in her opinion) willful ignorance start to get on her nerves.
  • Honey Trap: For Gaeta.
  • "The Reason You Suck" Speech: Delivers an absolutely heartbreaking one to Felix when she reveals what she was actually doing on New Caprica.
    "Sweet" Eight: I didn't seduce you. Hope seduced you. And the more you ate of it, the less you saw... you ate yourself blind. [...] There's not much difference between my brain and yours, Felix. We can choose to not make the connection. You can see someone kill in front of you – twice – and still hang on to your ignorance. Instead of calling it a flaw, you call it "hope"... "Faith"... [scoffs] "Love."

     Hybrids 

Baseship Hybrid

Not to be confused with the little human-Cylon hybrid Hera, the Hybrid is a model between Centurions and humanoid Cylons, which serves as the CPU of a Cylon Basestar.

  • Instant Oracle: Just Add Water!: Is always stuck in a tub of water. Used to provide the trope image. Concept art reveals she doesn't actually have legs; her torso merges into a slug-like lump of flesh inside the tub.
  • Living Ship: She is the CPU of a Basestar.
  • Mad Oracle: Her words are half gibberish, half prophecy.
  • Space Ship Girl: Is the being that pilots and maintains the Cylon baseship.
  • Wetware CPU: A humanoid woman submerged in a tub of water with complete control over Basestar functions.
  • Word-Salad Horror: Most of what they say are nonsensical and unsettling turns of phrase that can also be viewed as prophetic visions.

     Centurions 

Cylon Centurions

https://static.tvtropes.org/pmwiki/pub/images/centurion_on_pegasus.jpg

The original Cylons in the Twelve Colonies, being robotic servants created to help support humanity before they Turned Against Their Masters. Now, they commonly appear as the basic foot-soldier of Cylon ground forces and source of manual labor.

  • Chrome Champion: Both the early and modern models of Centurions have chrome-covered armor.
  • Cyber Cyclops: A notable case in that their "eye" is a horizontal red LED light that swoops from side to side.
  • Do Androids Dream?: The earlier Centurion models definitely fell into this, while the modern models are a more ambiguous case until Natalie Faust's faction removed their Restraining Bolt.
  • Distinguishing Mark: The rebel Centurions in Season 4 are marked with red stripes on their armor.
  • Dumb Muscle: Their primary purpose among Cylon society. Subverted when Natalie Faust removes their Restraining Bolt and they slowly prove themselves to be just as self-aware as the humanoid Cylons.
  • Fantastic Slur: The Colonials derisively referring to Cylons as "toasters" is based on the Centurions' design.
  • Heel–Face Turn: Angry over the Raiders being lobotomized by Cavil, many of the Centurions turn to the side of the rebel Cylons after they're granted free will.
  • Made a Slave: The original Cylon Centurions were self-aware on at least some level, what with them having Turned Against Their Masters, being smart enough to work together with the Final Five to create the humanoid Cylons, and being motivated by their desire to be as close to human as possible because of their religious beliefs. However, the modern Centurions were enslaved by the humanoid models and treated as Just a Machine until the Cylon Civil War broke out.
  • Mechanical Evolution: The earlier models of Centurions are noticeably bulkier and have harder edges, while the modern models are smoother with more elegant designs.
  • Mooks: Their entire role in Cylon society is to serve as expendable, loyal, and elite soldiers.
  • Mundane Utility: They're seen being used as construction workers and gardeners on Cylon-occupied Caprica along with guarding the humanoid models and attacking La Résistance.
  • Mythology Gag: The versions of the Centurions from during the First Cylon War strongly resemble those seen in the original series.
  • Natural Weapon: Not literally, obviously, but their fingers terminate in viciously sharp claws that serve as their primary weapon in close-quarters combat.
  • Obviously Evil: The new Centurions look intimidating, certainly, helped by the fact that the humanoid Cylons gave them angry slanted visors.
  • Restraining Bolt: The humanoid Cylons keep control over the modern Centurions with "telencephalic inhibitors" that keep them from becoming truly sentient. Notably, they cannot hurt any humanoid model unless given a direct order to do so (though they did harm members of the Final Five until they were "activated" and they learned of their true pasts). The Twos, Sixes, and Eights later remove these inhibitors, much to the dismay of the other Cylons.
  • Retractable Weapon: Their machine guns are normally concealed inside of their arms.
  • Roaring Rampage of Revenge: They inflict their vengeance upon their corrupt masters (both the Colonials and Cavil's faction of Cylons) and then some.
  • The Speechless: They are never seen speaking, apparently communicating with other Centurions and Raiders through a wireless network.
  • Turned Against Their Masters: Angry over being treated as slaves, they revolted against the Colonials. Many of them also revolt against Cavil's faction of Cylons after Natalie Faust gives them free will.

     Raiders 

Cylon Raiders

https://static.tvtropes.org/pmwiki/pub/images/kg_cg_ns_advanced_raider_002_6.jpg

The space fighters used by the Cylons in their war against humanity. While originally manned by Centurions during the First Cylon War, the modern Raiders are actually autonomous drones that utilize Organic Technology and can even be reborn upon death like the humanoid models.

  • Ace Pilot: Given enough traumatic deaths and they can develop into terrifyingly lethal killing machines, as seen with Scar.
  • Attack Animal: They're described as being far less intelligent than even the Centurions, being more akin to trained animals than actual soldiers. This is implied to be one of the main reasons why they frequently resort to the Zerg Rush.
  • Born-Again Immortality: Just like the humanoid models, Raiders are downloaded into new bodies on death as long as they're within close enough range of a Resurrection Ship.
  • Conservation of Ninjutsu: Practically exaggerated. One lone Raider - Scar - is a terrifying and dangerous Ace Pilot, while swarms of Raiders are regularly slaughtered in droves by the Colonial Vipers.
  • Cyber Cyclops: They sport one that strongly resembles that of the Centurions. Notably, it serves the double purpose of allowing the Cylons to transmit computer viruses.
  • Flying Cutlery Spaceship: They're sleek, slim unmanned vessels with two huge blade-like wings containing missiles and cannons. The red eye-stripe on the "cockpit" certainly helps with the image too.
  • It's Personal: Repeated resurrections can cause Raiders to develop what can only be described as a desire for revenge, as seen with Scar.
  • Imperial Stormtrooper Marksmanship Academy: With the notable exception of Scar, they best fit this trope among the Cylons. Consider how many are usually shown in combat and how relatively light Colonial casualties are compared to what they should be whenever the two forces fight.
  • Just a Machine: invoked Enforced by Cavil's faction of Cylons, who lobotomize the Raiders so as to make sure they keep fighting the Colonials despite them having recognized the Final Five being among them. This... doesn't go over well with some of the other models.
  • Leeroy Jenkins: Their primary battle tactic since they usually rely on their ability to be resurrected.
  • Lobotomy: The Ones propose doing this to the Raiders to make them more compliant after the Battle of the Ionian Nebula. With the Fours, Fives and Boomer's support the Ones' suggestion is passed and they begin "reconfiguring" the Raiders. In response, the Twos, Sixes and Eights remove the Restraining Bolt from the Centurions.
  • Mooks: They form the bulk of the Cylons' spaceborne forces.
  • Screw This, I'm Outta Here!: Upon recognizing Samuel T. Anders as one of the Final Five, the swarm of Raiders currently attacking Galactica immediately break off and refuse to fight, giving the Colonials the opportunity to escape.
  • Took a Level in Badass: As the series goes on, Raiders are seen making greater use of stealth and ambush tactics, which prove far more effective at blowing the inexperienced Colonial pilots to bits. Justified since (obviously) more and more Raiders are killed as the series goes on and repeated resurrections allow Raiders to "learn" from their previous mistakes and become more proficient killing machines.
  • Zerg Rush: Cylon Basestars can carry absolutely massive numbers of Raiders into battle, to the point that from a distance, Raiders being deployed from Basestars look like swarms of insects emerging from a hive more than anything else.

Other Entities

     "Head" Characters 

Head-Six

https://static.tvtropes.org/pmwiki/pub/images/TropeSix_4099.jpg
"For once, Gaius, you can stop manipulating the world and let destiny take its course. If there's one thing we know about human beings with certainty: they are masters of self-destruction."
Played By: Tricia Helfer

Introduced early in the series, "Head-Six" (as she's known in the writer's room) seemed to be a reincarnation of Caprica-Six (one never showed up when the other was around for a long time) that only Baltar could see, and essentially served as Baltar's conscience. She tends to goad him onward into taking actions he would rather not, sometimes even using physical violence to get the job done; she also seems to enjoy seducing him in plain sight.

  • Ambiguous Situation: It's completely unknown if she appeared to anyone aside from Baltar and Caprica-Six. Anders mentions that on Earth he saw a woman and Tory saw a man, but it's unclear if these are the same two angels or different ones, especially since in "Maelstrom" Kara saw one that looked Leoben and in Caprica Zoe saw one that looked like herself. In fact, it's ambiguous whether Head-Six and Head-Baltar take multiple forms, since they still look like Six and Baltar when the audience sees them in the final scene of the series 150,000 years later, although they're not really Six and Baltar.
  • Bastard Girlfriend: She frequently abuses Baltar when he argues with her; grabbing his face, throwing him into walls, screaming at him, and even snapping his neck once. It was in their head-mansion, so it didn't kill him, but it still smarted.
  • Blue-and-Orange Morality: Doesn't see things the way everyone else does. In fact, she outright states that the "God" she serves isn't good or evil, but a "force of nature."
  • Breakout Character: In large part thanks to Tricia Helfer's amazing performance, Head-Six was written in so that the writers would be able to have more fun with Six while keeping the Cylons and Colonials separated, and is overall one of the most popular and memorable characters in the whole show.
  • Deadpan Snarker: Her sense of humor can be quite dry, suffice to say.
  • Ethereal White Dress: One of her other frequent oufits which she usually wears when focused on more spiritual matters. She's wearing white when she appears to Gaius during his time on Kobol, the homeworld of humanity, and in the Opera House visions.
  • Fantastic Racism: Seems to have a low opinion of humanity.
  • Guardian Angel: Is revealed to be this, in her own words "an angel of God sent here to protect you, to guide you and to love you".
  • Iconic Outfit: Her short red dress.
  • Lady in Red: She wears several different fabulous outfits over the course of the series but her most iconic one, and the one she's most often seen wearing in promo images, is a very flattering red dress.
  • Large Ham: A lot of scenes with her and Baltar eventually devolve into him cowering with fear as she screams at him from the top of her lungs.
  • Mind Screw: The details of what exactly she is are inconsistent and confusing. At first she claims to be a projection created by a Cylon microchip that Caprica-Six may have implanted in his brain (fans joked that he was letting the bitch live rent-free in his head—literally). Later, she conveniently disappeared to put him in the awkward position of mistaking Shelly Godfrey for her. Then she declared herself to be a schizophrenic hallucination caused by Baltar's weak-minded inability to accept that he was responsible for the genocide of 11 billion people - but she was just using reverse psychology on him. And then she revealed that she was an angel sent by God.
  • Moral Myopia: She's utterly distraught at the thought of the Colonials repaying the Cylons in kind as they destroy the Resurrection Ship.
  • Ms. Fanservice: Even more than the rest of the Sixes, given her iconic red dress and other revealing outfits.
  • Not-So-Imaginary Friend: At one point she actually picks Baltar up to face the guard at his cult's quarters, and we (and the rest of the people) see him being lifted by an invisible being.
  • OOC Is Serious Business: While normally unflappable, she is absolutely horrified to discover what has been done to Gina Inviere.
  • Our Angels Are Different: She's confirmed to be an actual angel by the end of the series.
  • Spirit Advisor: Her main role, beside being an awful tease, is to guide Gaius, give him advice, or simply tell him what to say.
  • Time Abyss: She's countless millennia old.
  • Troll: She really likes to screw with Gaius's head for her own amusement.
  • Well-Intentioned Extremist: The Series Finale implies that she and Head-Baltar (along with the resurrected Kara Thrace) are servants of "God" sent to help break the Vicious Cycle and ensure peace between mankind & artificial intelligence. The fact that Head-Six frequently acts as a Bastard Girlfriend to Gaius is just part of her job.

Head-Baltar

Played By: James Callis

With Tricia Helfer on-set as Head-Six most of the time, it took a while for episodes to come out that focused on Caprica-Six. When they aired, audiences were startled to discover that she had a corresponding Head-Baltar walking around with her. He tends to be more observant as opposed to coercive, often coming up with answers that shouldn't be possible.

  • Ambiguous Situation: It's completely unknown if he appeared to anyone aside from Caprica-Six and Baltar. Anders mentions that on Earth he saw a woman and Tory saw a man, but it's unclear if these are the same two angels or different ones, especially since in "Maelstrom" Kara saw one that looked Leoben and in Caprica Zoe saw one that looked like herself. In fact, it's ambiguous whether Head-Six and Head-Baltar take multiple forms, since they still look like Six and Baltar when the audience sees them in the final scene of the series 150,000 years later, although they're not really Six and Baltar.
  • Blue-and-Orange Morality: Like with Head-Six, he doesn't see the world like the Cylons and humans do.
  • Deadpan Snarker: A lot of his advice and insight comes across this way. For instance, here's his below response to Caprica-Six when she's talking about Baltar's lake house to Boomer in "Downloaded":
    Caprica-Six: (fondly) I always loved the view. Sunlight on the water. It's my favorite spot in the universe.
    Head-Baltar: (drily) Yeah, it's magical. Too bad you nuked it.
  • Fantastic Racism: Shows a rather low opinion of Cylons while in Caprica-Six's head.
  • Foil: To Head-Six. Both are Deadpan Snarkers and Spirit Advisors to their charges, but she is more of a coy tease while he's far blunter and colder. The contrast between the two characters is perhaps best shown in "Downloaded," where instead of being jokey like Head-Six would've been in his situation while Caprica-Six is enjoying tea with D'Anna in a former Colonial park, he just glares at her with naked disgust and then bitterly remarks on how there used to be children playing in the park before the Fall of the Twelve Colonies.
  • Not-So-Imaginary Friend: The fact that Baltar is eventually able to see him to helps confirm to the audience that he's Real After All.
  • Mr. Fanservice: He's played by James Callis, after all.
  • Our Angels Are Different: All but stated to be an actual angel by the end of the series. However, Ron Moore actually describes him as a "devil" to Caprica-Six.
  • Spirit Advisor: Just like Head-Six for Baltar, his main role is to guide Caprica-Six, give her advice, or simply just tell her what to say.
  • Time Abyss: Like Head-Six, he's countless millennia old.
  • Walking Spoiler: The mere fact that he exists confirms to the audience that both he and Head-Six are not only Real After All, but that they're something far more eldritch than either man or Cylon.

     Hera 

Hera Agathon

The first-ever human-Cylon hybrid. President Roslin orders her death faked and the actual infant assigned to a foster mother, who is killed on New Caprica, causing the child to fall into the hands of the Cylons...

  • Adam and/or Eve: The finale shows that she essentially became "Mitochondrial Eve", the mother of all humanity on Earth. The concept is a real one.
  • Creepy Child: Downplayed - she generally behaves like a normal kid but her nature and destiny make her do worrisome things.
  • Fantastic Medicinal Bodily Product: Hera's hybrid blood temporarily cures Roslin's cancer. It later stops working when she ages out of being a baby since her fetal stem cells are explained as being the real "cancer cure" that worked for Roslin.
  • Half-Human Hybrid: The first human-Cylon hybrid.
  • Living MacGuffin: Being a hybrid, the Cylons (desperate to figure out how to reproduce) are keenly interested in her.
  • Plot-Relevant Age-Up: Averted. She ages naturally through her time on the series.
  • Waif Prophet: Her drawings turn out to have vital information to help humanity.
