6. Sarah Michelle Gellar
Sarah kicked an untold amount of big bad beastie butt in her starring role as the titular character in Buffy The Vampire Slayer. For seven seasons we watched her and the rest of the Scooby Gang battle all manner of Hellmouth-y evil. Although Sarah has shied away from action roles since Buffy wrapped in 2003, her time on Buffy was more than enough to secure her place on our list.
