Emily Thorne, Revenge
Don't mess with Emily Thorne (Emily VanCamp). Just don't. Revenge's heroine might not be as in control of her revegenda as she'd like, but she's still one of the scariest TV protagonists this side of Walter White. She'll tear down the Hamptons brick-by-expensive-brick until her father is avenged, and we'll cheer her on the whole way.
