Euron Greyjoy
All the Greyjoys seemed made this list. Euron is Theon’s and Yara’s uncle who killed their father so as to claim the Salt Throne. While Pilou Asbæk has done an impressive job in playing his character the show, unfortunately, had ignored a lot of what makes Euron intimidating. Euron resembles his nephew and niece in the show but he should be otherworldly scary according to the books. In Martin’s books, his hair is “black as a midnight sea”. A black leather patch covered Euron’s left eye, but his right was blue as a summer sky,” and his “lips looked very dark in the lamplight, bruised and blue”- to indicate his addiction to the narcotic beverage named the ‘shade of the evening.’
