Leader of "The Fleet". A veteran, a father and a grandfather. The one thing he hates other than the Cylons is politicians. He has set out on a quest to find the lost "Thirteenth Tribe" in the hopes that the two groups can fight back against the Cylons.
I Minored in Tropology: During the Count Iblis story, we learn that Adama had studied Telekinesis when he was attending military academy; he invokes 90% of Your Brain , and reminisces to Apollo about how his wife made him promise to stop bending spoons with his mind. This gets used as a possible excuse to Do In The Wizardry of Count Iblis' miracles.
Invincible Hero: He tends to give off this vibe, especially when he's in command of the entire fleet. Even the doubtful Tigh still follows Adama unquestionably, and maybe one or two members of the Council want to take him down a peg.
Action Dad: Well, action adoptive dad to be exact. Why? Because he's a Viper pilot.
Batman Gambit: Apollo is known to pull this, especially if the lives of his friends are at stake.
In "Murder on the Rising Star", the only way Starbuck could be acquitted from murdering Ortega was to have Baltar positively identify Karybdis, the latter's fellow collaborator and the real killer. Apollo purposely lets Karybdis aboard the shuttle before picking up Baltar from the Prison Barge. Apollo knows he and Baltar would both likely be killed as Karybdis turns out to be Pallon, who works as a waiter aboard the Rising Star.
"Baltar's Escape" has Apollo and Starbuck helping Wilker fixing up the two Cylon pilots for Baltar who has the Council of the Twelve as well as Boomer and Sheba (along with two "Blackshirts") captive. Apollo's plan? The shuttle takes off as planned, but Baltar finds out too late that these Cylons aren't functioning properly, which allow Apollo and Starbuck to remove the detonator and recapture him.
It Is Not Your Time: After Apollo is killed by Count Iblis, his body is taken aboard the Ship of Lights. The "angels" there say that Apollo was not meant to die and that Ibis had broken their laws by killing him. They then bring him back to life.
Invincible Hero: Let's just say everytime he comes up with a hunch, he always ends up being right.
The Kirk: Being the most moral character in the show, it's no surprise he fits well into this role.
Man Hug: He and Starbuck share this in "Lost Planet of the Gods, Part 2" when the latter was released by the Cylons.
Starbuck: "Don't you know it's against regulations to hug a junior officer?"
Apollo: "Not if I mean it."
Manly Tears: The ending of "Lost Planet of the Gods, Part 2", when Serena dies from her injuries. There's also a smaller instance in "Fire in Space" when he's reunited with his family in the Life station.
There's really only one word to describe Lt. Starbuck... trouble. Name the scam or scheme and chances are Starbuck has tried it, or he'll get around to it. Good at heart and an excellent pilot. Unfortunately he's also a classic con-man - most likely he gets it from his old man, Chameleon.
The Lancer: To Apollo; shares this role with Boomer.
Love Triangle: With Athena and Cassiopeia. He and Cassiopeia were also in this with Cain during "The Living Legend", which was resolved by Cain himself when he decided to take on the two basestars alone.
What the Hell, Hero?: In "The Man with Nine Lives", he calls Apollo and Boomer out for investigating Chameleon but then forgives them when he finds out for himself that Chameleon has conned him into protecting him from the Nomen who put him on their blood trail.
Lt. Boomer (Herb Jefferson, Jr.)
Ace pilot. Smart enough to stay away from Starbuck during his "Get Rich Quick" schemes. Whenever Starbuck and Apollo are both missing in action, Adama counts on him to command Blue Squadron.
Boomer: "A Viper is flown from a seated position."
Former Teen Rebel: Implied by Boomer himself when he mentions he spends more time hot-wiring hovormobiles than doors. Which makes one wonder...
Freudian Trio: With Apollo and Starbuck; the Ego of the group, tries to balance out the other two.
Green-Eyed Monster: It's not that he doesn't like Apollo and Starbuck. It's just the fact that he's tired of losing to them in Triad matches, and he doesn't realize that making a deal with the devil would only make matters worse.
Heterosexual Life Trio: Again, with Apollo and Starbuck. Those secret handshakes between the three warriors say it all. Not to mention him and Apollo being the only ones who believe Starbuck's innocence in "Murder on the Rising Star".
Apollo: "Hey, I've never seen you fuss so much."
Boomer: "I guess I would feel better if I were going."
Apollo: "We need you to lead the squadron."
Boomer: "But it doesn't change the way I feel."
The Lancer: To Apollo; shares this role with Starbuck.
Mr. Fixit: Which he displays when he hotwires the door to open in 'Fire In Space'.
Only Sane Man: The one most likely to point out how insane Starbuck's schemes are.
The Smart Guy: He is more familiar with all things science than most warriors, and is apparently a skilled mechanic who can hotwire anything but best with hovor-mobiles (as evidenced in 'Fire In Space').
Athena is Adama's daughter and Apollo's sister who has feelings for Starbuck and he has feelings for her... and Cassiopeia... and Aurora... and Merium. Sometimes she just wants to hit him on the head, and she may very well have.
Greater Need Than Mine: In the pilot when Starbuck tries to get her medical attention for her broken arm, she insists "There are others in greater need than I".
Hooker with a Heart of Gold: Her original profession is as a Socialator, apparently a largely respectable profession in Colonial High Society, and she has a gracious and generous personality to make that claim believable.
Defrosting Ice Queen: During her initial introduction, Sheba is a realist with a tough exterior but during her time aboard the Galactica she forms a friendship with the rest of the crew - even Cassiopeia.
Apollo's adoptive son. Boxey is a bright and outspoken boy who loves adventure. Boxey lost his beloved daggit/dog Muffit when the colonies where destroyed. So Muffit II was created to take his place. Now the pair are almost always together. Both Boxey and Muffit have used their unique talents to save lives many times.
Chronic Backstabbing Disorder: In order to have his way, he destroys needed fuel tankers to force Adama to attack a base. Adama calls him on this, everyone expects him to backstab again, and no one is surprised when he disobeys orders again in a later attack.
Heroic Sacrifice: Though whether or not he survived during the confrontation is unknown.
Informed Ability: Commander Cain is famous as a bold commander, brilliant strategist, and an inspiring leader. In practice, his leadership consists of swaggering around boasting about himself and sneering at others, and his strategy is Attack! Attack! Attack! It works, mostly because Baltar is an idiot and he is a tactful competent general.
Jerk with a Heart of Gold: Sure, he can be very deceptive when it suits him. But overtime, he grows to care for Starbuck. Indeed, the warrior turns out to be his own son - a fact which he told only Cassiopeia.
The Big Guy: In the Blue Squadron. Shares this role with Jolly.
Heterosexual Life-Partners: With Jolly. Only elements of this come to play in the show, but is delved a little deeper in the novelizations.
Flight Sergeant Ortega (Frank Ashmore)
Asshole Victim: He was murdered by Karybdis. But it's only because he has blackmailed him along with two other men who sneaked aboard the fleet using aliases, and was also a jerk to some other warriors - but especially Starbuck.
Women Are Wiser: At least one Siress, Tinia, comes to have a right mind when the Galactica is under attack by Baltar and his fellow escapees.
Baltar (John Colicos)
Baltar is not a Cylon - he's the man who sold humanity out to the Cylons. A chronic liar and coward, he loves to think of himself as superior to everyone else. He thinks he's using the Cylons when they're the ones using him. Of course none of that matters becuase he could never do the one thing they wanted him to do - destroy the Galactica.
Chronic Backstabbing Disorder / The Starscream: In "Lost Planet of the Gods", he tries to get into a position to backstab either the Cylons, the Rag-Tag Fleet, or both at once — and not even the audience is sure where he actually wants to aim the knife. It all ends with him pinned under rubble at the bottom of a Space-Egyptian pyramid when both sides refuse to trust him.
The smartest Cylon in the whole universe. He has the brains, the style, and most importantly, he's modest. His only handicap? Having to work under Baltar. Despite this handicap Lucifer seems to enjoy his banter with Balter, or perhaps he just like watching him sweat when things get hairy. Lucifer is probably the funniest and most likable villian anywhere.
Likable Villain: It's funny really. Lucifer isn't likable becuase he does good things or isn't as bad as he says. It's because he's so good at calling Baltar out on his hammy nature. That's probably why we love him so much.
The Rival: Baltar believes Lucifer has a rivalry with Spectre.
God Test: He claims to have great powers and knowledge. The Council of Twelve gives him three challenges: to deliver their greatest enemy (Baltar) to them, to lead the fleet to Earth, and one more to be named later.
Creepy Child: Robbie Rist's incarnation of the character in the three-part pilot story. This was changed to him having a much more normal personality in the following episodes thanks to Executive Meddling.
