In the books
In the A Song of Ice and Fire novels, Prince Oberyn is hot-headed younger brother of Prince Doran Martell. He has eight bastard daughters, called the Sand Snakes, the four youngest of which by his current paramour, Ellaria Sand.
Oberyn has a lined face with thin eyebrows, black "viper" eyes and a sharp nose. His hair is lustrous and black with only a few silver streaks and recedes from his brow into a widow's peak.
Oberyn is called "the Red Viper" by friend and foe alike due to his penchant for coating his weapons in lethal poisons, so that even a glancing wound will prove fatal.
