Game of Thrones: 10 Times Girls Run the World in Season 6

How She Slays: Ellaria is, of course, responsible for the death of Myrcella Baratheon, but it goes much deeper than just that. After the death of her lover, Oberyn Martell, Ellaria seems to lose all shreds of mercy. She orchestrates a coup and kills King Doran Martell and his heir, Trystane, vowing that "weak men will never rule Dorne again." Then, she takes the throne.
