21. Stannis Baratheon vs. the Wildings
Season 4, Episode 10: "The Children"
Here he comes to save the day! Until this moment, steely Stannis seemed in many ways to be the least appealing of Iron Throne's claimants: obsessed with the rule of law, unfriendly even to close advisors, prone to black sex-magic rituals, et cetera. But at the moment when things were darkest for the Night's Watch and the realm they protected, the Lord of Dragonstone and his men came from out of freakin' nowhere to cut down the Wildlings before they could overwhelm the Wall. In that fateful charge, Stannis the Mannis showed he wanted to win the crown by winning over the people, not the other way around.
