19. Stannis Baratheon
What if you were the rightful king of Westeros, but nobody cared? That was the predicament of the late King Robert's unsmiling sibling. His brother Renly, his rival Robb Stark, both of Jaime and Cersei's sons (yes, even Joffrey) – all of them are more appealing than this so-called Lord of Light. Actor Stephen Dillane made every ounce of Stannis's resentment visible onscreen, whether he was fighting to save the realm from the wildlings or sacrificing his own daughter to his cause. Only in death, at the hands of Brienne of Tarth, did he seem to find peace.
