5. Yara Greyjoy After a previous rebellion was suppressed, the Greyjoy scion, Theon, was sent off as a hostage to live with the winners, to ensure his family's future compliance,. This forced his sister, Yara, to step into the breach and become a son by proxy, commanding her own longship and leading her men as they pillage nearby territories. To quote her father: "She's commanded men. She's killed men. And she knows who she is." That's more than Theon does, completely failing to recognize the hard-ass she has become, when he returns, after almost a decade away.
