7. Simon Tam - Firefly
If you saw timid little Simon Tam finagle his way onto Serenity, you would be forgiven for thinking that he was a pushover and probably wouldn't last one day in cowboy space. Of course you'd be wrong, because for a nerdy little doctor, he's a lot tougher than he looks. And God help you if you bring his little sister River into it. Because he will end you. It's obvious that he's smart, but at first you might underestimate him. He's just a doctor, you might think. I can get the upper hand on him. But he is shockingly calculating and manipulative when he wants to be. The plan that he hatches to steal medical supplies and get River to the high-tech hospital on Ariel is a thing of beauty. Oh, and one more thing. I don't want to be the shallow one, but can we just talk for a second about how he spends 3/4s of Objects in Space shirtless? When exactly does he work out? Does reading books give you abs? Because if so I've been doing it all wrong.
