10. Eddard Stark (Game of Thrones)
Not to spoil anything for you, but this is a spinoff that would need to take a different route in order to be successful. So what better way to go at it than to take a trip through the past. Isn't everyone a little bit curious about the history between Ned Stark and his history with the late king Robert Baratheon? Though we know that Robert trusts Eddard, even proclaiming him the Hand of the King, the depth of their relationship is still mysterious throughout the series. We gather pieces here and there. We know that some of Ned's family was killed at the hands of the Mad King. Then, with the help of Ned himself, Robert managed to dethrone the psychotic Targaryen and captured the throne for himself. Through that long, vicious battle, surely Ned and Robert managed to find themselves some adventure and excitement. And best of all, if we got to see a Ned Stark prequel series, we would go into it beforehand not having to wait for Sean Bean's character to die like we do in every other role he plays.
