Emma Swan, 'Once Upon a Time'
Who: Jennifer Morrison
What: Technically, she's human... ish. She's the Only Hope for the fairy tale world, though, so she's a little different from the guy picking his nose in line at the supermarket, you know?
Powers: She will find you. And when she finds you, she will know exactly when you're lying to her. And she looks fantastic in that tiny version of Clark Kent's "Smallville" leather jacket.
Quote: "There's not a lot I'm great at in life. I have one skill. Let's call it a superpower. I can tell when anyone is lying, and you, kid, are."
