Oberyn Martell was a powerful, lustful man with a quick mind and a prickly tongue. He was known for his duels, temperament, keen intellect, and fleshiness, which made him extremely popular in Dorne.
Oberyn traveled the world in his youth and even fought in a mercenary company in Essos - his skills with a spear were sufficient to evenly assert himself against the dreaded Gregor Clegane in a duel. He had a very close relationship with his sister Elia and they were inseparable as children. Oberyn was also close to his older brother Doran, although their temperaments were very different. While Doran had been brought up to inherit the Dornish throne, Oberyn could indulge in the willful ways that were common among the Dornishmen.
Oberyn was also a very intelligent man: he studied at the Citadel for several years before deciding that the future as a Maester was just boring and he was leaving. During this time he studied poisons extensively, often with which he coated his weapons. He could also see that strong armor would affect his combat ability, preferring the unpredictability and flexibility of the strength.
Oberyn in particular was a deeply passionate man with a hot temper that often led to duels and resentments. but to the same extent, this made him deeply loyal to those who were important to him, such as his siblings, his lover Ellaria and his daughters.
Even though he was a very serious man, he was in a very relaxed, easy-going posture, absorbing everything that got in his way, but he was not incapable of being deadly serious if the situation insisted.
