Unbearably cruel to the son he himself shipped off to his enemies in order to save his own skin, the lord of the Iron Islands relentlessly berates Theon, forcing him to choose between betraying his closest (only?) friend Robb Stark or reject his own family. Played by Patrick Mallahide, this guy makes Tywin Lannister look like the father of the year, but his cruelty appears to have helped his kids conquered the North. He's like the Joe Jackson to Theon and Yara's Michael and Janet.
