Oberyn Martell
The Red Viper: Doran's hot-blooded younger brother — poisoner, duelist, scholar and lover — who has never forgiven the Lannisters for the murder of his sister Elia.
The fuller tale
Oberyn Martell arrives in the story trailing a legend the story then spends a season confirming. The Red Viper of Dorne earned the name at sixteen — a duel over a lady with old Lord Yronwood, fought to first blood, after which the wound festered and the whispers said poison on the blade; his own nephew's telling adds that Oberyn was sent to Oldtown afterward, where he forged six links of a maester's chain for the pleasure of it, poisons prominent among his studies. He has soldiered with the Second Sons across the disputed lands, fathered eight bastard daughters on four women and raised every one of them to the spear, and treats the world's disapproval as a wine he particularly enjoys.
Under the flamboyance is a single unhealed wound with a date on it. His sister Elia was married to Rhaegar Targaryen and murdered in the Sack of King's Landing — raped and killed by Gregor Clegane with her babes, on orders no Lannister ever answered for — and Oberyn has spent seventeen years watching the realm agree to forget it. Everything the character does is downstream of that arithmetic: the hatred of Tywin's house, the needling of every Lannister in reach, and the courteous, smiling patience of a man who has decided that the confession is coming even if he must go and collect it in person.
His King's Landing season is the story's best extended duet of menace and charm. He arrives for the royal wedding as Dorne's councillor, interviews Tyrion in a brothel with a dagger's worth of implication per sentence, and delivers — in the books to Tyrion's face, in the show across a cell — the saga's finest account of the Sack and what it cost. His bond with Ellaria Sand, easy and unjealous and genuinely tender, gives the tale its one portrait of desire without possession; his kindness to the realm's dwarfs, bastards and unwanted is the same principle at social scale. Dorne, Oberyn keeps explaining to the capital's flinching courtiers, does not share the rest of Westeros's cruelties about birth — only its cruelties about debts.
Tyrion's trial hands him the collection errand shaped exactly like his life. Volunteering as champion against Gregor Clegane is justice, spectacle and autobiography in one gesture: the accused gets the realm's deadliest spear for free, and Oberyn gets the Mountain in a ring with no one to intervene. What he wants from the duel is never the killing — it is the accounting; the demand, repeated with every pass of the spear, that the crowd, the court and Tywin Lannister sitting above the sand hear the names said aloud. Elia Martell. You raped her. You murdered her. You killed her children. The story has no other scene where a single voice so completely owns an arena.
He is in the tale for less than a season of its run, and his fingerprints outlast houses. The duel's outcome fells Tyrion's last hope and lights the fuse under Dorne; his daughters and his paramour carry his rage forward into two very different plots; his brother's long plan is bent around the hole he leaves. The Red Viper's meaning is the one his life insisted on: the realm's polite amnesia about its crimes is a ledger, not a pardon — and somewhere, someone is always still counting.
The page and the screen
Book and show Oberyn are unusually aligned in character and diverge in aftermath: the books make him the trigger of the entire Dornish master-plot — his death radicalizes Arianne's generation, forces Doran to reveal the Targaryen pact, and leaves eight Sand Snakes (not three) for the prince to disarm — while the show routes his legacy into Ellaria's vengeance coup, a plot his book paramour explicitly argues against. Book texture the show trims: the Yronwood duel that named him, the maester's links, a stint founding a sellsword company, and his correspondence with the lamed Willas Tyrell — the books' sly proof that the Viper's venom was always selective. The brothel diplomacy and the cell-side account of Elia are both tellings' shared jewels, near verbatim.
In the show, season by season
Season Four. In Two Swords — "The Lannisters aren't the only ones who pay their debts." In Mockingbird — "I will be your champion." The viper picks the fight he came for. In The Mountain and the Viper — "Say her name!" He needed the words more than the win.
In the books
A Storm of Swords. In The Purple Wedding and the Trial — "Say her name!" — he needed the confession more than the victory.

The Red Viper danced circles around the Mountain in Tyrion's trial by combat, demanding a confession for his sister Elia. He got the confession — with Gregor's thumbs in his eyes and his skull bursting in the Mountain's fists.
He dies in the duel he was winning, of the victory he actually wanted. Champion for Tyrion against Gregor Clegane, Oberyn fights the trial by combat entirely on his own terms — a spear against a mountain, wine in one hand in the books' telling, poetry of footwork in the show's — and puts the great knight down, poisoned steel through the armor's seams. Then, with the verdict his for the taking, he declines it: circling the fallen giant, demanding the confession, the name, the order-giver, refusing to end the collection before the debt is read out in full. The Mountain's hand finds his ankle; the rest is the story's most infamous minute — Oberyn borne down, thumbs in his eyes, his skull burst in Gregor's fists even as the dying monster roars out the confession at last. Both tellings agree on every essential, including the bitter accounting: the Viper got his names said, Tyrion got a death sentence, and Gregor got Oberyn's manticore-venom parting gift, which the books make the seed of something worse than death. Dorne's answer to the news fills the rest of both sagas.
