20. GENEVIEVE PADALECKI

Show: Supernatural
We don’t know how anyone wouldn’t find the witch turned demon Ruby charming in the supernatural (pun, obvious) series. After all, she did seduce a demon hunter, revealed herself a conniving traitor, and subsequently raised hell. OK, so the devil inside her had some issues, but we’ve got to give it credit for its fine taste in human hosts: first Katie Cassidy in season three, followed by Genevieve Padalecki in season four.
