Main Human Characters
William 'Bill' Adama (callsign: Husker)
Played By: Edward James OlmosAn almost-retired Commander whose assignment to the Galactica was a going-away present. 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.
- 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.
- 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, 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'.
- 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.
- 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.
- 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.
Played By: Mary Mc DonnellThe 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). 43rd 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 Colonies, she shares this role with Adama who leads the military.
- 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.
- Hanging Judge: She really likes doing this. 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 though.
- Iron Lady: She's far more stern than her opposition expects from a "kindergarten teacher."
- 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.
- Unexpected Successor: Forty-third in line, even.
Kara Thrace (callsign: Starbuck)
Played By: Katee SackhoffAn 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.
- Ascend to a Higher Plane of Existence: Her ultimate fate.
- Ax-Crazy: just a bit.
- Badass: An excellent all-around soldier, and unstoppable in the cockpit.
- 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.
- 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.
- Does Not Like Shoes: Appears barefoot quite regularly.
- Good Bad Girl: Due to being a Distaff Counterpart to her womanizing namesake from the original series.
- Jerkass:At times.
- The Lad-ette: Drinks, chomps cigars, and generally acts like one of the guys.
- 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, but she doesn't seem to fear death.
- Really Gets Around: Sleeps with anyone she fancies, even after she's married.
- She Cleans Up Nicely: Invoked by name, in fact.
- Star-Crossed Lovers: With Apollo.
- Wrench Wench: Has a few moments. Most notably when she got a Cylon Raider in working condition after she crashed.
Lee Adama (callsign: Apollo)
Played By: Jamie BamberThe 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.
- Badass: Like most of the military cast. Dangerous both in and out of the cockpit.
- 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.
- 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 probably one of the 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 abs.
- Platonic Life Partners: With Starbuck, or so they claim.
- Sharp-Dressed Man: When he gets into politics.
- Star-Crossed Lovers: With Starbuck.
- Straight Man: Something of a straight man for the entire crew.
- "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.
Played By: James CallisA 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.
- A God Am I: Has his moments.
- 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, womanising 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.
- Deadpan Snarker: You couldn't go through everything he does without developing a sense of humour about it.
- Dirty Coward: 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.
- Handsome Lech: He attracts women fairly easily, but he's quite the perv.
- Hookers and Blow: The Baltar administration was marked by its groundbreaking lap dance & 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.
- Only, 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.
- Jerk with a Heart of Gold: He is quite compassionate and emotional, believing firmly that War is not an excuse for inhumanity.
- The McCoy: He's probably the most emotional person in the series.
- Messianic Archetype: As of 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?
- Narcissist: He remains pretty self-absorbed throughout the series.
- 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.
- 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 gun.
- Villain Protagonist, deconstructed: Baltar isn't malicious, just a selfish coward (ie. not a hero like most of the other cast) with the occasional flash of incredible Genre Blindness.
Battlestar Galactica Military
Played By: Michael HoganAfter 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.
- Achilles in His Tent: After New Caprica, he becomes a drunk wreck for a while. Notably, one script that was written before this was decided had to hastily replace his role with Lee, resulting in Lee looking quite out of character as a hardline anti-Cylon bigot.
- The Alcoholic: He puts the "fun" in "functional alcoholic." And his wife just makes him worse.
- Bald of Awesome: He's bald, he's 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.
- 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."
- Fake Guest Star: Tigh is in all but four episodes of the show. The only characters to appear more frequently were Madam President and The Old Man himself.
- Fake Memories: His recollections of the First Cylon War most significantly.
- 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, I 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 sympathise with Saul.
- Jerk with a Heart of Gold: But he's still a good man at heart.
- 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.
- Poisonous Friend: He's kind of hell on Bill's sanity, though he really doesn't mean most of it.
- Reincarnation Romance: He and Ellen were married originally too, and somehow found each other again after Cavil wiped their memories.
Played By: Aaron DouglasSenior Chief Petty Officer 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.
- 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.
- 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.
- Cartwright Curse: He is just not lucky in love...
- 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.
- Humiliation Conga: 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.
- Number Two: As the highest-ranking NCO in the fleet, Tyrol has aspects of this.
- Mr. Fixit: Chief mechanic.
- Stoic Spectacles: In his original life.
- Took a Level in Jerkass: Not surprising, given the Humiliation Conga he went through.
Karl Agathon (callsign: Helo)
Played By: Tahmoh PenikettA 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.
- Badass: Like most of the cast.
- 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: to Athena
- Heterosexual Life-Partners: Has shades of this with Lee.
- Knight in Shining Armor: The closest you can get to on this show.
- 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.
- Nice Guy: One of very, very few in the show.
- Papa Wolf: Especially to Hera, but also Athena.
- Why Do You Keep Changing Jobs?: Since his primary role is pretty much "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...
Played By: Alessandro JulianiFirst appearing as a CIC watch officer, he eventually gets assigned to Dr. Baltar as a personal aide. He's an idealist—which is a bad thing to be in Galactica's World Half Empty; losing his leg in Season 4 is only one link in a "Break the Cutie" chain. Eventually leads a mutiny with Tom Zarek, which 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.
- Bi the Way: Just sort of turns out to be bisexual with no fanfare.
- 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. Shame it was Gaeta having his leg shot half off and then amputated, rather than, say, a morale concert - but still...
- 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 heart breaking 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.
- Hollywood Atheist: Averted.
- Hypercompetent Sidekick: During President Baltar's reign, which unfortunately makes him the fall guy for the later Cylon occupation.
- Straight Gay: Well, straight-ish.
- Well-Intentioned Extremist: When he leads a mutiny, he's doing it for 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, while Zarek is unable to convince Gaeta they need to concentrate on more pragmatic issues.
Anastasia 'Dee' Dualla
Played By: Kandyse McClureA 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:
- Driven to Suicide: Seriously, who saw that coming? The signs were apparently there, but were very subtle and overshadowed by other things at the time. Makes the entire episode Harsher in Hindsight.
- Heroic BSOD: When she's Driven to Suicide.
- Mission Control: Along with Communications Officer, part of her job.
- Romantic Runner-Up: She got Lee after he didn't get Starbuck. Some fans felt she had it coming after what she did to Billy.
Cally Henderson Tyrol
Played By: Nicki Clyne
"I just joined to pay for dental school."An enlisted deckhand serving Galactica's flight wing, Cally is known for a few things: having only one name for two seasons (her full name wasn't given until her funeral!); being a Plucky Girl (sometimes too much so), 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.
- 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.
’Doc’ Sherman Cottle
Played By: Donnelly RhodesA grumpy Major and the fleet's leading medic, he serves on Galactica and lectures his patients in between drags from a cigarette. His first name, Sherman, was only revealed during the series finale.
- Ascended Extra: Was just a medic, but wound up playing a significant role in a few episodes.
- Deadpan Snarker: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 not nice to his patients...
- No Name Given: His first name is only given in the finale.
Brendan Costanza (callsign: Hot Dog)
Played By: Bodie OlmosFrom 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.
Played By: Michael TruccoAn athlete on pre-massacre 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. Becomes a major figure in the resistance on New Caprica, not to mention Starbuck's husband.
- Ascended Extra: Joins the main cast after being rescued.
- 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...
- Badass: His first appearance is as part of a resistance cell on Caprica. Does a similar thing on New Caprica.
- Game of Nerds: Or its in-universe equivalent, Pyramid. In the final episode, Anders — arguably the least cerebral of the Cylons — is revealed in 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 realise 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.
- Real Life Writes the Plot: Trucco suffered a similar spinal injury to Christopher Reeve's in a car crash, resulting in Anders' bullet to the head. He went on to make a near-miraculous full recovery and was able to be an action hero again in "The Plan."
- Space Ship Boy: In order to save his life, he gets linked up to a Cylon Basestar.
Louanne 'Kat' Katraine
Played By: Luciana CarroA "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.
- 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 operation to be better than sex.
- Dead Person Impersonation: Has been masquerading as a dead girl, as her own identity wouldn't have gotten her into the military.
- 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.
- New Meat: How she's introduced.
Played By: Rekha SharmaSpecial Aide to the President, replacing the deceased Billy Keikaya. Word of God is that Tory was chosen as one of the Final Five precisely because she hadn't yet had much character development. 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, coupled with a dose of "Ascended Fanon?"
- Ascended Extra: Started out just as an aide, wound up being one of the Final Five.
- Reincarnation Romance: Averted. 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. Ultimately averted in the hardest way possible.
Played By: Paul CampbellPersonal 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.
- 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 few cuties on the show.
- Reckless Gun Usage: The man doesn't know how to handle a gun, and it shows.
Played By: Kate VernonTigh's wife, who miraculously survived the Destruction of the 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.
- Aww, Look! They Really Do Love Each Other: Saul and Ellen.
- 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.
- Lady Drunk: She also brings out the worst in Saul.
- Lady Macbeth: Oh my god, yes. 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 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.
- Team Mom: Post-resurrection.
- 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.
Played By: Richard HatchWell-Intentioned Extremist working for the common man; whether that's true or not, he's definitely good at politics. After inhabiting the Heel-Face Revolving Door for several seasons, he settles on the bad-guy side, leading a mutiny against Roslin and Adama.
- 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 Phelen after he learns of the latter's child prostitution ring.
- 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.
- Averted during his disastrous coup later in the show.
- 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.
- 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.
- Well-Intentioned Extremist: At first, anyway.
Played By: Mark SheppardAn 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.
- 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.
- Sunglasses at Night: a character quirk.
Played By: Michelle ForbesCaptain of the only other (known) battlestar to survive the massacre of the Twelve Colonies, Cain adopted a much more ruthless attitude towards survival.
- 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.
- 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.
- 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.
- I Did What I Had to Do: Has no remorse over the awful things she's done.
- Insane Admiral: Not fully insane, just... devoted.
- 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 tipoff she's not all sunshine and rainbows.
- Names to Run Away From Really Fast: See Name of Cain.
- 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.
- Omnicidal Maniac: She's obsessed with revenge. Anybody who doesn't toe the line or serve an immediately-valuable purpose gets a bullet through the head.
- Psycho Lesbian: According to Blood And Chrome. 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.
- The Unfettered: Won't let anything stop her quest, not pesky morals or human lives.
- Well-Intentioned Extremist: She does want humanity's survival... but at any cost.
Played By: Brad DryboroughFrst 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.
Played By: Graham Beckel
- Just Following Orders: Takes no responsibility for the awful things the Pegasus' crew has done.
- 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.
Played By: Stephanie Jacobsen
- 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...Jesus H. Christ.
- Evil Counterpart: Well, maybe not quite 'evil', but she's a counterpart to Starbuck.
- 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.
Played By: Fulvio Cecere
- Fantastic Racism: Cylons aren't people to him.
- Pet the Dog: Apparently saved Fisk and one other Pegasus crew member's lives.
- Rape Is a Special Kind of Evil: His job description apparently includes raping as a form of torture.
Played By: John HeardOriginally 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.
- Unexpected Successor: Originally the chief engineer of the Pegasus, it is suggested that he was one of the only high-ranking officers left.
Played By: Steve Bacic
- Boom, Headshot: Turns out Admiral Cain doesn't care for alternatives.
- Death by Origin Story: Fisk wasn't kidding about that Noodle Incident...
- Nice Guy
- 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.
The result of collaboration between the Centurions and the Final Five, each of these models has many copies, some of which have received more character development than others. The last five humanoid Cylons to be revealed turned out to be major players in the human fleet, and the only survivors of a previous Cylon generation pre-dating the Colonies' Centurions.
- Artificial Human: Until the massacre, no one knew humanoid Cylons existed.
- Cloning Blues / Clones Are People Too: Mostly the Final Five.
- Me's a Crowd: While they don't share memories, each model does share a personality.
- Ridiculously Human Robots: The humanoid Cylons are more or less impossible to identify.
- You Are Number Six: Mostly referred to by their model number.
Brother John Cavil/Number One
Played By: Dean StockwellInitially 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....
- Affably Evil / Faux Affably Evil: Mostly the latter, but since there are more than one of him, it gets a little tricky.
- Ancient Keeper (in Season 3)
- 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 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.
- 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 likely 'boxed' by the other Cavil, as he's never seen again.
- The Chessmaster: They've been controlling and setting everything up.
- Cool Old Guy: If You can ignore the genocide and sadism.
- Deadpan Snarker: As good as Baltar.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?
- 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 being well into his sixties and completely homicidal.
- Manipulative Bastard: Not just the humans, but they manipulate other Cylons as well.
- Morality Pet: The parentless boy in The Plan. Subverted in that Cavil kills him when he realizes this trope is in effect.
- This also qualifies for an Actor Allusion: The boy's costume is an exact copy of Stockwell's costume in "The Boy with Green Hair".
- Motive Rant: "I don't want to be human!""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.
- 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. Squick indeed. At least she spent their time as an amnesiac...
- Pinocchio Syndrome: as you can tell from the Motive Rant, Cavil has this in reverse.
- Redemption Rejection: He rejects an offer at redemption from his mother in "No Exit".
- Rage Quit: In the finale, he just says "Frak this" and eats a gun.
- The Sociopath: He doesn't care about other people.
- 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.
- Villain Protagonist: In "The Plan" movie.
- 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. Y'know, being born old might have something to do with why he's so cranky.
Leoben Conoy/Number Two
Played By: Callum Keith RennieOne 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 in all fairness 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 him.
- Genius Bruiser: He's possibly the strongest of the cylons and incredibly 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 download. He never seems especially angry with Starbuck over it either.
- Magnificent Bastard
- 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 realises who it's pilot was. He never interacts with Starbuck after that point.
- Slasher Smile: Any time 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: 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.
D'Anna Biers/Number Three
Played By: Lucy LawlessIntroduced 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 other cylons.
- 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 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.
- Hot Scoop: Her cover identity.
- Moral Myopia: Even by Cylon standards, she's pretty bad. She constantly preaches about God and condemns humans for Their brutality, conveniently forgetting that Cylons wiped out six billion humans.
- 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
Played By: Rick WorthyIntroduced as a doctor running what turns out to be a "Farm"—a giant lab where Cylons experiment with biological reproduction—Simon is polite and well-spoken, the opposite of the Scary Black Man (Cylonism notwithstanding).
- A Day in the Limelight: He gets more character development in "The Plan" than he ever did during the series.
- Affably Evil: He's perfectly nice to Starbuck when he's in the farm.
- Bald of Evil: Bald, Cylon.
- Becoming the Mask: One of the copies in "The Plan".
- Deadly Doctor: Considering he's performing research in order to figure out how to get Cylons to be able to reproduce like humans.
- Redemption Equals Death: The copy in "The Plan".
Aaron Doral/Number Five
Played By: Matthew BennettIntroduced 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.
- 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.
- 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 sakes!
- 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.
Played By: Tricia HelferThe Femme Fatale Cylon who seduces Baltar, she is later embraced as a hero by her people, and her voice given extra weight in their democracy—even when she suggests that the Cylons attempt peaceful co-existence with humanity. Eventually travels to Galactica along with Athena and Hera, where she spends a lot of time in the brig frakking Saul Tigh, eventually conceiving a (short-lived) child with him. She also joins Baltar in the final battle, and it's implied that the two of them, at least, get a Happily Ever After. Other significant Sixes include Shelly Godfrey, Gina Inviere, Natalie Faust, Lida and Sonja.
- The Atoner: Begins to feel regret for her role in killing most of the humans.
- Blondes Are Evil: at first.
- Beauty Is Never Tarnished: Usually played straight with Head Six, averted in a number of cases with corporal 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.
- Honey Trap: Given the model's attractiveness, it's not surprising they're used for this.
- Lady in Red: Her Memetic Outfit.
- 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.
- Ms. Fanservice: A slinky red dress is among the least provocative of her outfits.
Played By: N/ABasically 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 fans that no, Daniel's sudden existance was not indicative of any other plot twist around the corner.
Sharon Valerii/Number Eight (callsign: Boomer)
Played By: Grace ParkIntroduced 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....
- 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.
- Heel-Face Revolving Door: She has severe Chronic Backstabbing Disorder.
- Killed Off for Real: In the end.
- Manchurian Agent: She had no control over herself when she shot Adama. Even worse, since she was never "activated" again after Cavil visited her in the brig, she never remembers how the vicious asshole emotionally tormented her. So when she turns up as Cavil's squeeze in Season 4, the son of a bitch is still manipulating her. If that doesn't make you want to empty a magazine into Cavil's face and dump him out the airlock, you must not have a soul.
- The Mole: For the Cylons.
- Ms. Fanservice: Plenty of nude scenes of Eights.
- 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 trying to save Hera.
- Trauma Conga Line
- Tomato in the Mirror: Boomer had no idea she was a Cylon.
- The Woobie: Her Chronic Backstabbing Disorder is understandable, as her life is utter hell. She's forced to betray the people she loves, is Driven to Suicide but fails, everyone she cares about hates her guts, her attempt to make peace between humans and cylons backfires catastrophically, and she ends up in a self-destructive relationship with the lecherous evil old bastard Cavill, who manipulates her into doing even worse things. Sometimes flirts with Woobie, Destroyer of Worlds.
Sharon Agathon/Number Eight (callsign: Athena)
Played By: Grace ParkAfter 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 Heel-Face Turn was almost inevitable. She then became the first Cylon character to openly side with the humans.
- Action Mom: Having Hera doesn't slow her down.
- 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. She wound up doing just that.
- High Heel-Face Turn: Sides with the humans due to love for Helo.
- Mama Bear: She'll do anything to protect Hera.
- Undying Loyalty: Lacks the Heel-Face Revolving Door of her counterpart Boomer; in fact Athena's fanatical devotion to the Colonial cause may be an attempt to compensate for this weakness in the Eight model. That and the fact that the slightest indication of treachery would get her thrown out an airlock.
Played By: Tiffany Lyndall-KnightNot to be confused with little Hera, the Hybrid is a model between Centurions and humanoids, which serves as the CPU of a Cylon Basestar.
Played By: Tricia HelferIntroduced 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.
- Blue and Orange Morality: Doesn't see things the way everyone else does.
- Guardian Angel: is revealed to be this, in her own word "an angel of God sent here to protect you, to guide you and to love you".
- 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 said that he was letting the bitch live rent-free in his head—literally). Then she conveniently disappeared to put him in the awkward position of mistaking Shelley 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. Then she revealed that she was an angel sent by God.
- Ms. Fanservice: Even more than the rest of the Sixes.
- Not-So-Imaginary Friend: At one time 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.
- Spirit Advisor: her main role, beside being an awful tease, is to guide Gaius, give him advice, or simply tell him what to say.
Played By: James CallisWith 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.
- Deadpan Snarker: A lot of his advice and insight comes across this way.
Played By: Lily Duong-Walton, Alexandra Thomas, Iliana Gomez-MartinezThe 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...
- Creepy Child: She tends to draw worrisome coloring books.
- 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. The creators stated that they wouldn't "hyper-age" her and they didn't.
