Naveen Andrews as Sayid Jarrah
Sayid lives to kill another day. He's all James Bond like that. Sayid rules.

Adewale Akinnuoye-Agbaje as Mr. Eko
After Mr. Eko was killed by the smoke monster in season three, he was never seen or heard from again. We suspect that won't change in season six.
Michelle Rodriguez as Ana Lucia Cortez
Rodriguez has been amenable to return appearances in the past, and we'll likely see Ana Lucia at least once more before the series wraps for good.
Nestor Carbonell as Richard Alpert
Richard will no doubt be key to finally explaining the show's many mysteries, and as such, Lost's most beloved mystery man has been promoted to series-regular status.
Henry Ian Cusick as Desmond Hume
Desmond will only be a recurring character in season six, not a regular, but we're choosing to believe that's because he's living happily ever after with Penny Widmore and little Charlie.
Jeremy Davies as Daniel Faraday
The son of Eloise Hawking and Charles Widmore has to be in the final season, right?
Emilie de Ravin as Claire Littleton
She's ba-a-ack! After being MIA for the duration of season five's time-traveling hijinks, Claire returns in season six from her strange sojourn with daddy Christian and/or Jacob in the cabin.
Michael Emerson as Benjamin Linus
What's this about "pre-redemption"? Oh Ben, you magnificent bastard.
Matthew Fox as Jack Shephard
Did Jack make the right call when he decided to use Jughead to knock the gang back to future? We'll find out beginning Feb. 2 when Lost returns to ABC.
Jorge Garcia as Hugo "Hurley" Reyes
If you asked us to bet on the identity of Lost's last man standing, we'd have to pick Hurley. If anyone's going to have the last (hilarious) word, it's going to be our boy Hugo Reyes.
Maggie Grace as Shannon Rutherford
Sayid's one-time love will be returning to Lost late in season six.
Daniel Dae Kim as Jin Kwon
Jin has yet to meet his own child, Ji Yeon, but that better change before the end of season six.
Yunjin Kim as Sun Kwon
Expect Sun (and her money) to be crucial in defeating Charles Widmore and his evil empire.
Josh Holloway as James "Sawyer" Ford
Sawyer still struggles with Juliet's choice to let go at the end of season five.
Malcolm David Kelley as Walt Lloyd
Will we ever see Walt again? Show runner Carlton Cuse tells us, "We would love to have him back, but he has aged and looks older than his character." Excuses, excuses...
Ken Leung as Miles Straume
Marvin Candle's kid has an uncanny ability to chat with the dead, and who knows, that might have something to do with how all these long-lost characters come back into play.
Jeff Fahey as Frank Lapidus
Cool pilot Frank has been upped to series-regular status for the final season.
Evangeline Lilly as Kate Austen
Kate continues to be front and center in the series. Look for her to gravitate back to foster son Aaron, but of course she's still entangled with Lost's notorious love polygon.
Rebecca Mader as Charlotte Lewis
Lost producers confirmed via Twitter that Charlotte, who died early in season five of time-travel sickness, makes an encore performance in season six.
Elizabeth Mitchell as Juliet Burke
The sixth-season premiere, entitled "LA X," explores what happens after Juliet detonated "Jughead" in 1977. (And then Mitchell returns to headlining her own ABC sci-fi series, V.)
Dominic Monaghan as Charlie Pace
Producers report that Monaghan, who now stars on ABC's FlashForward, appears in four episodes of Lost this season.

Terry O'Quinn as Locke (or Unlocke?)
Locke is dead at Ben's hand and has been replaced by the character fans call UnLocke. What is UnLocke's mission? Is UnLocke good or evil? Tune in to season six to find out.
Harold Perrineau as Michael Dawson
Michael was seemingly killed in the freighter explosion at the end of the season four, but producers confirm that he does appear in season six.
Zuleikha Robinson as Ilana
We thought she was just a bounty hunter looking for Sayid, but as it turns out Ilana might have some major family ties to the Island, and her character is a season-six regular.
