23. Khal Drogo
A Genghis Khan in guyliner, Drogo began as a brutal barbarian and ended at the hands of an infected wound and black-magic medicine. But in between, he developed into one half of the show's most rapturous romance (not to mention its most unlikely and, perhaps, disturbing, considering the manner in which it began). Given Jason Momoa's magnetic, sumptuously shirtless performance, who wouldn't eat their hearts out for that?
