As you know, Clementine is from 1881 Tombstone, Ariz., but she's also an avid time and space traveler.
Specifically, she's a proud member of the Firefly-class spaceship, Serenity.
Five hundred years in the future there's a whole new frontier, and the crew of the Firefly-class spaceship Serenity is eager to stake a claim on the action. They'll take any job, legal or illegal, to keep fuel in the tanks and food on the table. But things get a bit more complicated after they take on a passenger wanted by the new totalitarian Alliance regime. Now they find themselves on the run, desperate to steer clear of Alliance ships and the flesh-eating Reavers who live on the fringes of space.
Firefly premiered in the United States on Sept. 20, 2002, but was canceled after 11 episodes. Despite the series' relatively short life span, it received strong sales when it was released on DVD and has large fan support campaigns.
The post-airing success of the show led to a 2005 film, Serenity, based on the series. The Firefly franchise expanded from the series and film to other media including comics and a role-playing game.
Personally, I think Clementine looks like a young Zoe Alleyne Washburne—second-in-command of the Serenity.
