Originally I was going to go with another Firefly character, but I felt like I'd sang the praises of that show enough. So I shifted my attention to another great badass chick, GENERAL SAMANTHA CARTER! played by the beautiful and talented, Amanda Tapping!
So where to begin with this woman here. From the very first fucking episode, she says it in the blackest black and whitest white, just because she's female doesn't mean she can't handle this crap. But you know what happens when she says it? She's cut down for thinking it. It's immediately established, that any shit her team commander gives her, will not be because she's female, it'll be because she's a scientist. And throughout the series, her intelligence and her tactical skills save her ass, her friends' ass, and her team's ass. She's snarky, she's a leader, she's a genius, she's just brilliant. I'd go into further detail, but my memory is failing me, as I have not seen this character on television since her last 2 appearances in SGU.
