Prince Oberyn Martell of Dorne, a.k.a The Red Viper. Brother of Prince Doran Martell, and father of several bastards, known as The Sand Snakes.
Bisexual, ardent, skilled with poisoned spears and an excellent warrior. Not the conventional Prince Charming, true, but there's a reason why all the girls that made Wolfsister's meme- me included- mentioned him as the one they'd take to bed if they could choose among all the men in Westeros.
I dedicate this drawing to Jesatria, and to all the girls/boys out there that would love to do Oberyn. He'd love to do you too, you know.
