Main Human Characters
Commander William 'Bill' Adama (callsign: Husker)
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.
- 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.
- Badass Mustache: For a while.
- Beard of Sorrow: He's unshaven in "33" shortly after the destruction of the colonies.
- 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.
- Catch Phrase: "Sometimes you gotta roll the hard six."
- ("...What does that mean, sir?" "I dunno, it's, it's something my dad says.")
- 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 crossover comic.
- 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.
- 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.
- 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-martialling and discharging him would have blown the cover on 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.
The Secretary of Education under President Richard Adar (sometimes literally under), 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.
- Big Good: As President of the Twelve Colonies, she shares this role with Adama who leads the military.
- 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. It is the reason she's called "Madame Airlock", after all.
- 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 timespan - 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 assassinating 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.
Lieutenant Kara Thrace (callsign: Starbuck)
An excellent pilot with a rebellious streak a mile wide. This makes her Crazy 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 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.
- 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.
- The Ace: Even before the vast majority of the fleet was killed, she was one of their best pilots.
- Broken Ace: She's haunted by her past, and is just a bit unhinged.
- The Alcoholic: While she's a relatively high functioning alcoholic as compared to Col. Tigh, she still drinks more than what would be considered healthy and Katee Sackhoff herself once stated that Kara "drinks most of her calories".
- Amazonian Beauty: Downplayed, as she's not a bodybuilder or anything like that, but her choice of career naturally makes her pretty athletic, which only accentuates her beauty.
- 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 itself to be Kara, it's at least hinted that it was actually an angelic entity sent by "God" for the sole purpose of leading the Colonials to Earth-2.
- Blasphemous Boast: While training the new pilots in Season 1, she insists that they all 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: Lost her dad, her mom was an abusive hardass, and lost her fiance - and that was all before the Cylons attacked. Her treatment at the hands of Leoben on New Caprica ends up pushing her into full-on Death Seeker territory.
- 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 Awesome: She's a bit unhinged, but no less badass for it.
- Daddy's Girl: She seemed to like her pianist father Dreilide a lot more than her strict mother Socrata, though he later abandoned them.
- Death Seeker: Gradually evolves into one over the course of the series.
- Does Not Like Shoes: Appears barefoot quite regularly.
- 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 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.
- Jerkass: She's often rude, insensitive, hostile and insubordinate which can occasionally lead her into conflict with other officers onboard the Galactica, particularly Col. Tigh.
- Jerk with a Heart of Gold: However, not only does she have a softer side, but she's also incredibly dedicated and loving (in her own way) to her friends and loved ones.
- Killed Off for Real: She really did die when her Viper exploded inside the gas giant; her later appearances are that of an angelic entity using her visage.
- 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.
- Additionally, her name of "Kara Thrace" sounds phonetically similar to the phrase "carry the race." The Series Finale reveals that she was brought Back from the Dead to do just that.
- Military Brat: Kara's mother was in the military and she spent most of her childhood traveling from one colony to another.
- Ms. Fanservice: Often wears short tank tops when not in military gear, and is one automatically by virtue of being played by Katee Sackhoff.
- My Greatest Failure: She blames herself for Zak's death.
- Not Afraid to Die: Part of why she's so Crazy Awesome. She's not a Death Seeker — at first, anyway — but she doesn't seem to fear death.
- 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.
- 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.
- Screw Yourself: Literally. She sleeps with original series Starbuck in the crossover comic.
- She Cleans Up Nicely: Invoked by name, in fact.
- Star-Crossed Lovers: With Apollo.
- 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 helpign make sure everyone finds the new Earth.
- Wrench Wench: Has a few moments. Most notably when she got a Cylon Raider in working condition after she crashed.
Captain Lee Adama (callsign: Apollo)
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. 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: Far more estranged with his father than original series Apollo was.
- The Big Damn Kiss: Gives one totally out-of-the-blue to Kara when she returns from Caprica with the Arrow of Apollo. In a subversion, she's rather bewildered and everyone else just sort of stands around awkwardly.
- Calling the Old Man Out: Does this many times to his father Bill.
- 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 sereis as Galactica's CAG (Commander of the 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.
- 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 are.
- Sharp-Dressed Man: When he gets into politics.
- Star-Crossed Lovers: With Starbuck.
- Straight Man: Something of a straight man for the entire crew.
- 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.
Dr Gaius Baltar
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.
- 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 hes partially responsible for it) Helo even gives up his seat on the Raptor for him because of his status as a renowned genius scientist, and hes elected as Capricas quorum delegate without having sought the position.
- Deadpan Snarker: You couldn't go through everything he does without developing a sense of humour about it.
- 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.
- 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.
- 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.
- 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.
- 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.
- Omnidisciplinary Scientist: Since The Main Characters Do Everything, he's basically in charge of "science" on the Galactica, including both computer science and biology.
- 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.
- Religious Robot: Inverted; he's a missionary spreading Cylon monotheism to the humans.
- 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.
- The Smart Guy: Initially, he's pretty much the source of science advancement on Galactica.
- 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.
- 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 Saul Tigh
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.
- 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. Hes painfully aware of this and makes it clear the entire time that he really doesnt 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 Galacticas crew's lack of acknowledgement or gratitude of everything the Resistance did during the Cylon occupation. He also gives this to Galacticas 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.
- 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.
- 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.
- 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.
- Time Abyss: Like the other members of the Final Five, he is technically well over two millennia old.
- 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.
Senior Chief Petty Officer Galen Tyrol
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.
- 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.
- 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.
- 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.
- Time Abyss: Like the other members of the Final Five, he is technically well over two millennia old.
- 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 she cheated on him and 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.
Lieutenant Karl Agathon (callsign: Helo)
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.
- The Fettered: He has issues, but they make him among the most normal in the cast.
- Happily Married: After her HeelFace Turn, he and Athena come to have perhaps the most stable relationship on the 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 than another 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 he's not as likely to bend the rule as Lees nor is he as willing to cross certain lines even if it may be for the greater good.
- 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 in the entire cast of characters.
- 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...
- Nice Guy: One of very, very few in the show.
- Mr. Fanservice: Has an erotic sex scene with Athena in Season 1 and also has a Heroic Build.
- Papa Wolf: Especially to Hera.
- Platonic Life-Partners: With Starbuck; notably, he's one of the few male characters who she doesn't sleep with over the course of the show.
Lieutenant Felix Gaeta
First appearing as a CIC watch officer, he eventually gets assigned to Dr. Baltar as a personal aide. He's an idealistwhich 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 they lose.
- 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, ending with him being executed.
- The Cast Show Off: 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.
- 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.
- Game Changer: Zarek was never able to take power (despite being legitimately elected) because he never had the support of the military. Gaeta provides that support.
- Hypercompetent Sidekick: During President Baltar's reign, which unfortunately makes him the fall guy for the later Cylon occupation.
- Kick the Dog: Lies under oath just to get Baltar executed by saying he signed a mass-execution order with no resistance or protest, when he saw firsthand that the normally cowardly Baltar outright refused to sign the order, and only did so after the Cylons literally put a gun to his head.
- 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, which serves as a bit of a Despair Event Horizon.
- 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.
- Reality Ensues: 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.
- 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.
- The Stoic: Keeps a cool head under almost any situation which is frankly a bit of a requirement for someone in his position.
- Straight Gay: Well, straight-ish.
- 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, he is almost ejected out the airlock by his shipmates under almost no pretext, still treated like crap even after it becomes clear he was their inside source in Baltar's administration on New Caprica, accidentally loses his leg to friendly fire from Anders after a standoff between Starbuck and Helo, and Adama finally "betrays" him by allying with the rebel Cylons, (who are complicit in the near-genocide of their entire species), Gaeta finally snaps and turns against his former comrades, staging a coup d'état with Zarek.
Petty Officer Anastasia 'Dee' Dualla
A Twofer Token Minority first appearing as a Petty Officer manning to communications panel in Galactica's CIC in the miniseries, where she basically played the role of Uhura. Gets an officer's commission sometime between Seasons 2 and 3. Provides possibly the biggest Shocking Swerve in the series when, after a happy and successful date with her ex-husband Lee, and with absolutely no prior indicators, she blows her brains out.
- Ascended Extra: Gets more and more screentime.
- Communications Officer: Her main job.
- Driven to Suicide: After seeing the ruined Earth, she hits the Despair Event Horizon, and ultimately puts a gun to her head.
- 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.
Specialist Cally Henderson Tyrol
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.
- Ascended Extra: Just a member of the crew in the flight wing, but becomes a fairly major character.
- Attempted Rape: One of Zarek's flunkies tries to rape her in "Bastille Day" and she bites his ear off to defend herself.
- Break the Cutie: Bad things happen to her over the course of the series.
- Go Mad from the Revelation: After learning Tyrol is a Cylon, she sort of... snaps.
- Interrupted Suicide: After learning Tyrol is a Cylon, she considers suicide (taking her baby with her). Tory talks her out of it... just to make sure that the baby is safe, then kills her anyway.
- Plucky Girl: Her early characterization.
- Red Herring: Little Nicky was believed for quite a while to be another supposedly-impossible human-Cylon hybrid. Then it was revealed that, sometime before her wedding, Cally slept with Hot Dog.
- Sanity Slippage: Upon finding out the truth about Tyrol.
- Wrench Wench: Her role on the Galactica.
- Your Cheating Heart: With Hot Dog, apparantly.
Major Sherman "Doc" Cottle
- Ascended Extra: Was just a medic, but wound up playing a significant role in a few episodes.
- 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 in an opium den so you can have a little snooze.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.
- 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.
Lieutenant JG Brendan Costanza (callsign: Hot Dog)
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.
An athlete on pre-Fall Caprica, the star 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.
- 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...
- Game of Nerds: Or the in-universe equivalent, Pyramid. Notably, in the final episode, Anders — arguably the least cerebral of the Cylons — 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.
- 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.
- 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' bullet to the head. Trucco went on to make a near-miraculous full recovery and so Anders was able to become an Action Hero again in "The Plan."
- Spaceship Girl: A Gender Flipped example - in order to save his life, he gets linked up 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" has a Raider scan him and identify him as one of the Final Five. 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 Cylons and the humans & rebel Cylons settling on Earth-2.
- Time Abyss: Like the other members of the Final Five, he is technically well over two millennia old.
- Took a Level in Badass: He becomes a rather decent pilot after joining the fleet and being drafted into serving on Galactica.
- 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 to initially accept him actually being a Cylon.
Lieutenant JG Louanne 'Kat' Katraine
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.
- 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: Gets more characterization and focus in her final episode.
- Heroic Sacrifice: She continues on a mission well after she's exposed herself to a fatal amount of radiation.
- 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.
Lieutenant JG Alex Quartarro (Callsign: Crashdown)
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.
- Character Death: Baltar shoots him to stop him from killing Callie.
- Guy In Bacl: 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.
- Leader Wannabe: 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 hes under ultimately causes him to snap.
- Sanity Slippage: Crashdown starts to lose it after he gets two of his group killed, culminating in him trying to murder Callie.
Sergeant Allan Nowart
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.
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.
- Token Religious Teammate: He is the most religious person on Galactica, which winds up making him ally with Roslin.
Specialist Alonzo Socinus
A deckhand who works with Chief Tyrol.
- Character Death: He has to be given a Mercy Kill because of injuries he sustained in the Raptor crash on Kobol.
- 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.
- Reality Ensues: 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.
- The Scapegoat: He willingly takes the blame for a security breach that Tyrol would have been blamed for and lets himself be arrested. Tyrol hadnt known he would do this tries to confess to Adama, but Adama lets Socinus take the blame because he lied before the Council of Twelve and he cant spare Tyrol.
A deckhand who works with Tyrol and Cally.
- Character Death: 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.
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.
- 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.
Lieutenant JG Margaret Edmondson (callsign:Racetrack)
A cynical, somewhat nihilistic Raptor pilot.
- 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.
- HeelFace 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.
- Mauve Shirt: Out of the Raptor pilots, she appears the most and gets the most characterization.
Lieutenant Hamish McCall (callsign:Skulls)
A Raptor pilot who accidentally found Kobol alongside Racetrack.
Lieutenant JG Donald Perry (callsign:Chuckles)
An experienced pilot conscripted to be a Viper pilot.
- Character Death: Killed during a raid on the Cylon refinery when anti-aircraft bullets pierce his Viper.
Specialist James 'Jammer' Lyman
A deckhand who becomes a prominent supporting character during the New Caprica Arc.
Lieutenant JG Tucker Clellan (callsign:Duck)
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.
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.
- FaceHeel 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 dies.
- 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.
- 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.
- Time Abyss: Like the other members of the Final Five, she is technically well over two millennia old.
- 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 moments 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.
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.
- Dogged Nice Guy: To Dee.
- Fake Guest Star: He's practically a main character in the first half of the series, yet is always credited as guest star.
- Heroic Sacrifice: Gets shot dead pushing people out of the way of gunfire when a hostage situation turns into a Blast Out. Crosses over into Suicide by Cop, as he was despondent over Dee rejecting him.
- Kill the Cutie: One of the most unambiguously nice characters around, and gets killed quickly on.
- Reckless Gun Usage: The man doesn't know how to handle a gun, and it shows.
- Sacrificial Lion: He's the first main character in the series to die, during a Blast Out in what seemed to be a filler episode, re-establishing that Anyone Can Die.
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.
- Jerk with a Heart of Gold: Evolves into one post-Character Development.
- Lady Drunk: She also brings out the worst in Saul.
- Lady Macbeth: There's a reason fandom calls her "Lady McTigh".
- 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 Gets Around: 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.
- Team Mom: Post-resurrection.
- Time Abyss: Like the other members of the Final Five, she is technically well over two millennia old.
- 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.
- Walking Spoiler: Like her husband, she's one of the Final Five and a Cylon.
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 HeelFace Revolving Door for several seasons, he settles on the bad-guy side, leading a mutiny against Roslin and Adama.
- Affably Evil: Usually polite even to his enemies.
- 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, they genuinely adore him.
- Death Seeker: It's suggested by Lee that he's one.
- 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.
- 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.
- 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.
- 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.
- 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.
- In the first episode, he lectures Apollo on the meaning of his callsign.
- Not So Different: From Roslin.
- 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.
- 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.
- Well-Intentioned Extremist: At first, anyway.
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.
- 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 hi 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.
- Sunglasses at Night: A character quirk.
Tom Zarek's righthand man during the fleet schism.
A priest who serves as a spiritual advisor for Roslin.
President Richard Adar
The President of the Colonies prior to Roslin who was killed during the Cylon attack at the beginning of the series.
- Jerkass: Flashbacks show that he was an incompetent president who would rather kill innocent people than make a compromise and look weak.
- President Evil: He was willing to use military force to stop a peaceful protest by teachers, which would no doubt cause casualties, and gets angry with Roslin for compromising with them because he thinks it makes him look weak.
Rear Admiral Helena Cain
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.
- 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 mens 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: 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. Also, like Cain, Adama initially wanted to go after the Cylons for revenge.
- Adama had Starbuck torture Leoben just as Cain had Thorne torture Gina (albeit with no gang-rape). Also, Adama and Roslin are reasonable people, but don't broke much threat to their authority when it is threatened, much like Cain, as Tom Zarek repeatedly points out.
- 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.
Lieutenant Louis Hoshi
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 of all things.
- 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.
Colonel Jack Fisk
- Character Death: Phelan has him garrote for asking for too much money,
- 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 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.
Lieutenant Kendra Shaw
- The Atoner: No matter how she tries to rationalize it, she knows she's damned for executing Laird's wife and kids.
- 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 Colon ship 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.
Lieutenant Alastair Thorne
- 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: Hes 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.
Commander Barry Garner
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: Dies in space vacuum repairing the FTL drive to save the ship.
- 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.
- Unexpected Successor: Originally the chief engineer of the Pegasus, it is suggested that he was one of the only high-ranking officers left.
- Heroic Sacrifice: He freezes to death while repairing a coolant leak in the FTL drive so the Pegasus can escape a Cylon attack.
- 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.
- The Paranoiac: He believes Galactica is trying to set him up and Im return does his best to make life hell for any former Galactica crew onboard.
- 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.
Colonel Jurgen Belzen
- 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
- Number Two
- Only Sane Man: Tries to stop Admiral Cain from pointlessly sacrificing the lives of her crew and air wing. He failed to recognize that she wasn't suffering a Heroic BSoD, she had gone straight Ax-Crazy. See above for the result.
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.
- 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.
- Artificial Human: Until the massacre, no one knew humanoid Cylons existed.
- Cloning Blues: Mostly the Final Five.
- HeelFace 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: Some more than others, but for all their posturing towards humanity, it's a noted irony that their actions as a race are essentially driven by the pettiest of human emotions.
- Me's a Crowd: While they don't exactly share memories, each model does share an overall personality.
- Not So Different: All of them display rather human traits and flaws, such as insecurity, irrational hatred, a fear of rejection, a desire for meaning and acceptance, etc.
- Ridiculously Human Robots: The humanoid Cylons are more or less impossible to identify.
- You Are Number 6: Mostly referred to by their model number.
Brother John Cavil/Number One
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.
- Ancient Keeper: In Season 3.
- Asshole Victim: No tears are shed for him when he gets Killed Off for Real in "Daybreak."
- 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.
- 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 amazing 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, as he's never seen again.
- The Chessmaster: They've been controlling and setting everything in the series up so as to torment his creators.
- 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?
- 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 existence of the Final Five because it would get in the way of his own petty revenge scheme against them.
- Evil Old Folks: The oldest looking of the Cylons and by far the evilest.
- Faux Affably Evil: As the series goes on, his polite facade 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 calls him out as a sadist.
- 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.
- 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... Really, it'd be harder to find examples of Cavil not doing something utterly reprehensible.
- Manipulative Bastard: Not just the humans, but they manipulate other Cylons as well.
- Morality Pet: The orphaned boy in The Plan. Subverted in that Cavil kills him when he realizes this trope is in effect.
- Motive Rant: He really doesn't like his human form."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: 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. 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 failing 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.
- Redemption Rejection: He rejects an offer at redemption 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, but is an atheist himself. His actions become progressively more self-centered and lose even the thin veneer of any idealism as the series progresses.
- Token Good Teammate: 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.
- Villain Protagonist: For "The Plan".
- 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.
Leoben Conoy/Number Two
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: At first. 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 Final 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.
- 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.
- Not Afraid to Die: He doesn't fear death in the slightest due to his faith.
- Only Known by Their Nickname: His number isn't revealed for a few seasons.
- 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. None of this is beyond the ability of a well-conditioned human, and Adama still physically overpowered him and beat him to death (though it wasn't easy) so it seems unlikely beyond first glance that the Cylons have Super Strength (Cavill occasionally claims they do, but he is far too delusional to take at face value).
D'Anna Biers/Number Three
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 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.
- 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: Lucy Lawless described the character as "the ultimate narcissist" who sees herself as more "pure" than the other Cylons.
- Straw Hypocrite: Of the religious variety. She preaches about God and respect for life while ordering mass executions of innocent civilians.
Simon O'Neill/Number Four
Introduced as a doctor running what turns out to be a "Farm"a giant lab where Cylons experiment with biological reproductionSimon 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 he's in the farm.
- Bald of Evil: Bald, 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.
- Punch-Clock Villain: Unlike Cavil and Doral's 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.
- Redemption Equals Death: The copy in "The Plan" commits suicide to protect his wife and stepdaughter from Cavil.
Aaron Doral/Number Five
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.
- 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.
- 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. The fleet!Doral defensively says that he'd go unrecognized because his (identical style but differently colored) jacket is completely different.
- Jerkass: Even for a Cylon, he's not a nice guy.
- 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 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.
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 democracyeven 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".
- Convenient Miscarriage: Convenient's not 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.
- 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.
- My God, What Have I Done?: She quickly came to regret her part in the Fall of the Twelve Colonies.
- 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: 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 intended to be a peaceful coexistence. She's also the first Cylon to actually show regret over the Fall.
Gina Inviere/Number Six
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.
- 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 abuses, she recoils at any kind of touch.
- Meganekko: While in disguise as a Demand Peace activist.
- The Mole: Though she pretended to be like Boomer and acted like she was unaware of her true nature.
- Rape Is a Special Kind of Evil: Was on the receiving end of this by the Pegasus crew, who all had their way with her in some way or another.
- Tragic Villain: It's hard not to feel sorry for her given the hellish treatment she's gone through.
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.
- Only One Name: Daniel.
- Posthumous Character: No Sevens are ever actually seen.
- Red Herring: Not intentionally, but it took personal reassurances from the producers to convince some fans that no, Daniel's sudden 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.
Lieutenant JG Sharon Valerii/Number Eight (callsign: Boomer)
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....
- 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.
- Adaptation Relationship Overhaul: Not particularly close to Apollo or Starbuck, unlike her 1978 namesake.
- 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.
- Conveniently Unverifiable Cover Story: 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.
- HeelFace Revolving Door: She has severe Chronic Backstabbing Disorder.
- Killed Off for Real: In the Series Finale.
- 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.
- Ms. Fanservice: There's plenty of nude scenes of Eights.
- Race Lift: Original series Boomer was black. Sharon is Asian.
- 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. 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).
- Redemption Equals Death: Dies after saving Hera.
- Trauma Conga Line: The poor woman goes through absolute hell over the course of the series.
- Tomato in the Mirror: Boomer had no idea she was a Cylon.
- Wild Card: According to Cavil, the Number Eights have a propensity for Chronic Backstabbing Disorder.
Lieutenant Sharon Agathon/Number Eight (callsign: Athena)
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" (and before then had to be called Caprica-Boomer to differentiate) 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-HeelFace 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.
- 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 HeelFace Turn, she and Helo come to have easily the most stable relationship on the show.
- High-HeelFace Turn: Sides with the humans due to her love for Helo.
- 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.
- 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.
- Replacement Goldfish: Lampshaded In-Universe, she essentially becomes one for Boomer after she left for the Cylons.
- Undying Loyalty: Lacks the HeelFace 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.
Not to be confused with little Hera, the Hybrid is a model between Centurions and humanoids, which serves as the CPU of a Cylon Basestar.
- Instant Oracle: Just Add Water!: Is always stuck in a tub of water. Currently provides 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.
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 shows up when the other is around) 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.
- 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.
- 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: Her default outfit, 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. And then she revealed that she was an angel sent by God.
- Moral Myopia: She reveled in the deaths of fifty billion people when the Colonies were destroyed, but is 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' 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.
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 any other Sixes aside from Caprica-Six.
- 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. It even fits into how they describe themselves - Head-Six describes herself as "an angel," while Head-Baltar describes himself as "a devil." 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, he actually describes himself 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.
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.
