Oh, he's the King from the Song of Fire and Ice novels by George R.R. Martin. He had absolutely no legitimate claim to the throne, but he was so charismatic, handsome, and skilled in fighting, that he was able to lead a successful rebellion against the Mad King, and take the throne. He turned out to be a very poor leader, as good soldiers rarely make good kings, but take the throne he did.

Because I'm a nerd and feel obligated to point it out: He did have Targaryen blood. So technically, he had [i]some[/i] claim, just not the most legitimate.
