Edward James Olmos
Adm. William Adama
On BSG: The stalwart and seasoned commander of the titular Galactica, he helped protect the ragtag human fleet to the bitter end. Had a thing for formidable civilian leaders. Tended to growl.
Where is he now: After directing the 2009 what-the-Cylons-were-really-up-to Battlestar DVD postscript The Plan, Olmos will next appear opposite Seth Rogen in The Green Hornet (out Jan. 14), as Michael Axford, the dogged pursuer of the title hero.

President Laura Roslin
On BSG: A schoolteacher by trade and the Secretary of Education by title, she became the reluctant, and then indispensable, president after the Cylon massacre of humanity. Had a thing for formidable military leaders. Cancer riddled her body, twice, but it never robbed her spirit.
Where is she now: Earlier this month, McDonnell reprised her juicy role on The Closer as Capt. Sharon Raydor, a cop unafraid to butt heads with Kyra Sedgwick's Dep. Chief Brenda Leigh Johnson. She'll appear next April in Scream 4, hopefully for more than just a killer cameo.

Lee ''Apollo'' Adama
On BSG: At first an ace pilot chafing under the shadow of his father, Apollo eventually chucked the uniform for some pinstripe civvies. Had a thing for ne'er-do-well hotshot pilots. Lit the Interwebs ablaze when he (almost) dropped his towel.
Where is he now: Since Feb. 2009, Bamber has played more-or-less the Chris Noth role on Law & Order: UK, which just started its third season (or ''series,'' in the local parlance). Yes, that's right, there's even a British version of Law & Order.
4 of 15
On BSG: A slippery, traitorous, horndog scientific genius, he unwittingly allowed the Cylons to wipe out virtually all of humanity. Had a thing for willowy platinum blonde toasters. Found God, maybe.
Where is he now: Callis is still circling the sci-fi universe, first in a recurring role on the departed ABC's series FlashForward, and now as a series regular on SyFy's Eureka, which just concluded its fourth season.
5 of 15
Number Six, Caprica Six, etc.
On BSG: We met many versions (with many hairstyles) of the sixth Cylon model, most memorably ''Caprica'' Six, i.e. the one who seduced Baltar into betraying his own species. Had a thing for brilliant, self-serving weasels, and living in their heads.
Where is she now: A go-to TV guest star (Chuck, Warehouse 13, Human Target, Two and a Half Men), she now stars opposite Dylan McDermott on the TNT series Dark Blue.

Lt. Sharon ''Boomer'' Valerii / Lt. Sharon ''Athena'' Valerii
On BSG: ''Boomer'' was at first unaware of her Cylon status, until she attempted to assassinate Adama. Had a thing for blue-collar grease monkeys. Eventually, she went kinda evil. ''Athena'' was at first keen on destroying humanity, until she gave birth to a human/Cylon baby. Had a thing for earnest Adonis-y officers. Eventually, she fought alongside humanity.
On BSG: Park appeared on the Canadian immigration drama The Border, and starred in the A&E addiction drama The Cleaner. This fall, she'll star as Kona Kalakaua — her second reprisal of an originally male character from a bygone TV show (the first ''Boomer'' was a dude) — on CBS' big-budget reboot of Hawaii Five-0.
7 of 15
Kara ''Starbuck'' Thrace
On BSG: Ah, Starbuck. Nobody was a more kick-ass fighter pilot, and nobody was better at frakking up their personal life. Had a thing for beefy sports stars. And intense pilots with daddy issues. And creepy Cylons who liked to kidnap her. Died, then came back to life, maybe.
Where is she now: After infuriating audiences as CTU agent/Russian spy Dana Walsh on the final season of 24, Sackhoff will appear on CSI in a possibly recurring role starting in November.
8 of 15
Col. Saul Tigh
On BSG: Adama's irascible, alcoholic XO and inveterate Cylon hater was rather startled to learn he wasn't just a Cylon, he was one of the famed ''Final Five.'' Had a thing for boozy unrepentant flirts and, rather inexplicably, willowy platinum blonde toasters.
Where is he now: Hogan rode the guest-star gravy train for a time, appearing on Warehouse 13, Dollhouse, Numb3rs, and Psych. Next April, he'll star with Amanda Seyfried, Gary Oldman, and Julie Christie in director Catherine Hardwicke's big-screen retelling of the classic fairy tale Red Riding Hood.
9 of 15
Chief Galen Tyrol
On BSG: The top engineer on the Galactica, the Chief couldn't really catch a break: His first girlfriend was a Cylon, then he learned he was a Cylon, then his human wife was killed by another Cylon. Had a thing for plucky Raptor pilots and whiny deckhands.
Where is he now: This summer, Douglas headlined the (very) short-lived Canadian import The Bridge on CBS. He's currently starring in the CW college cheerleader drama Hellcats.
10 of 15
Capt. Karl ''Helo'' Agathon
On BSG: Ever loyal, he fathered the first human/Cylon hybrid baby and always looked good in a tank top. Had a thing for plucky Raptor pilots who were toasters.
Where is he now: He starred in one-and-a-half seasons of Joss Whedon's ill-fated Dollhouse. Last April, he headlined the two-part SyFy mini-series Riverworld, co-starring fellow BSG alum Alessandro Juliani.
11 of 15
On BSG: A professional athlete-turned-freedom fighter, Anders rescued Kara Thrace from the Cylons. Then Kara Thrace rescued him. Naturally, they got married. Sam was ultimately revealed to be a member of the Final Five. And his wife was the Messiah or something. Fun couple.
Where is he now: After guest-starring on V as the mysterious John May and romancing Beckett in a recurring stint on Castle, Trucco will be a regular in USA's new legal drama Facing Kate (debuting January 2011).
12 of 15
On BSG: The Cylon Number Three model was prone to soul-searching mysticism and general treachery. D'Anna's search for the Final Five (and her questionable taste in paramours) led to arguably the most existentially tragic destiny of any BSG character. (Put it this way: would you want to spend eternity in an irradiated wasteland?)
Where is she now: Lawless stars in Spartacus: Blood and Sand as Lucretia, who's sort of like D'Anna with more cunning and less clothes.
13 of 15
On BSG: Eternally flirtatious, eternally conniving, it was easy to think that Ellen was just a power-hungry Lady Macbeth-type. But she genuinely loved her Saul — in that amour fou kind of way — even when, because of her complex betrayal of the rebels on New Caprica, he had to give her a poisoned drink. Fortunately, nobody stays dead on BSG. (Except Billy.)
Where is she now: After briefly classing up the last season of Heroes with a guest appearance, Vernon appeared in the Miley Cyrus romance The Last Song.
14 of 15
On BSG: Poor Felix. An idealist by nature, he served tirelessly as the Galactica's tactical officer. But his poor choice in role models — he served as Chief of Staff during Gaius Baltar's apocalyptic presidency — nearly got him blown out of an airlock. He did end up losing a leg. Since things can always get worse in the BSG-verse, he ended up leading a mutiny on the Galactica.
Where is he now: Juliani's practically a Syfy regular, thanks to appearances in the miniseries Alice and Riverworld. He also has a recurring role on Smallville as Dr. Emil Hamilton.
15 of 15
On BSG: A minor but important player in the most important events in Colonial history, Dee was a key advisor to Bill Adama and the eventual wife of Lee Adama. (Dee and Lee — sounds like a folk song!) Arguably the most mysterious BSG regular, right up to her still-shocking, comes-out-of-nowhere exit.
Where is she now: McClure starred in NBC's mystery series Persons Unknown.
