Prince Oberyn Nymeros Martell, younger brother of Doran and Elia, was known for his sharp wit, fiery temper, passionate nature, and his appetite for both men and women. Also famous for his extensive knowledge of poisons and deadly, unconventional fighting style, he was nicknamed “Red Viper”. He hails from Dorne, which differs from the rest of Westeros: women are equal, can rule, homosexuality is accepted, and bastards are not despised

At sixteen, he dueled a nobleman after bedding his wife; the man died from infected wounds, sparking rumors that Oberyn used poison. He travelled across Westeros, Essos, and the Free Cities for years, taking delight in learning, figthing, and seeing other cultures. He studied at the Citadel, forging several maester's chain links before leaving out of boredom. He fought in Meereen’s pits, rode with the Second Sons, and later led his own sellsword company. He fathered several bastard daughters—the Sand Snakes—whom he claimed, raised, and loved, teaching them combat and independence, letting them decide whether they want marriage. He deeply loved his long-time paramour Ellaria Sand, mother to some of his daughters

Elia's murder by Ser Gregor Clegane during Robert’s Rebellion left him vowing revenge against Gregor and the Lannisters, believing Tywin ordered her and her children killed. Coming to King’s Landing to take Doran’s seat on the small council, his true goal was justice. He fought as Tyrion’s champion in trial by combat, seeking vengeance on Gregor while sympathizing with Tyrion over his sham trial and his mistreatment by his own family. Oberyn wounded Gregor with a poisoned spear, ensuring his death, but sought a confession for his crimes instead of killing him. Gregor struck back, crushing his skull. The next moment, Oberyn awoke in another world—unharmed, in his duel attire, unsure if he had died
