17. Viserys Targaryen
The John the Baptist to Joffrey Baratheon's Jesus Christ, Daenerys' big blonde brother was the first royal douchecanoe Game of Thrones rowed downstream. But unlike his larger-than-life successor, Viserys got a moment or two to seem human: first breaking down about his loveless, hunted life, then begging for said life before his brother-in-law boiled his brain with molten gold. He was no dragon, but he was a heck of a character.
