Gregor Clegane
The Mountain That Rides: Sandor's monstrous elder brother, near eight feet of murderous rage, Tywin Lannister's favorite instrument of terror.
The fuller tale
Gregor Clegane is what House Lannister keeps in the stable no one talks about. Nearly eight feet of him — the books' measurements grow with each witness — the Mountain That Rides is the head of a minor westerlands house with a kennel-keeper's grandfather and a knighthood personally conferred by Prince Rhaegar, a fact the story serves with maximum irony given what he does with it: at the sack of King's Landing, on Tywin's unspoken order, it is Ser Gregor who murders Rhaegar's infant son and rapes and kills his wife Elia Martell with the babe's blood still on him. That day makes him permanently useful and permanently deniable — the atrocity the Lannisters can order without ordering, the answer to problems a great house cannot be seen solving.
The tale's whispered accounting of his household is worse than his battlefield. Servants who talk disappear; two wives and a sister die conveniently; his father and a hunting accident part company suspiciously; and his little brother's face is the one atrocity with a living witness — the brazier, the toy knight, the burns half of Westeros can read but only the Hound can explain. Gregor is the saga's control experiment in unaccountable strength: not cunning, not ambitious, barely verbal — just an enormous capacity for harm attached to a temper, headaches that the books hint are eating him alive, and a liege lord who finds all of it useful. When Tywin wants the Riverlands bleeding, he does not declare war; he releases Gregor, and the raids that torch the Trident's villages are the war's actual opening — deniable, monstrous and effective, which is the whole job description.
His crimes finally purchase a formal reckoning in the saga's most famous duel. When Tyrion demands trial by combat for Joffrey's murder, Cersei names the Mountain her champion — and the prince of a country with a seventeen-year-old grievance volunteers for the other side. Oberyn Martell fights the duel as an interrogation, spear against greatsword, demanding with every pass that the giant say her name — Elia Martell — and confess who gave the order. He wins the fight and loses the interrogation's discipline: circling the downed Mountain for his answer instead of finishing him, he is caught, and Gregor supplies the confession as he crushes the prince's skull with his hands — he killed her, he says it plainly, and the saying is itself the horror. The duel condemns Tyrion, guts Dorne, and closes with its winner poisoned on the sand: Oberyn's spear was dressed with manticore venom, and the Mountain's dying begins before the applause ends.
What comes back from that poisoning is the story's quietest monstrosity. Qyburn requests the dying colossus for his cellars, and what eventually stands in Kingsguard white at Cersei's shoulder is officially a new man — Ser Robert Strong, in the books' careful fiction, a knight who never speaks, never eats, never sleeps, never lifts his visor; the show drops the pseudonym and shows the grey-fleshed face. In either telling the transformation completes the character's logic with terrible neatness: Gregor alive was already a weapon wearing a man; Qyburn merely removed the residue. His last career is bodyguard, executioner and walking argument for his queen — the champion appointed for Cersei's trial by the Faith, the silent presence that ends conversations, the fate worse than death that certain prisoners are handed to — a monster finally rendered fully manageable, which is all his employers ever wanted of him.
The page and the screen
The tellings differ mainly in how much dying he does. The books chronicle the poisoning in luxuriant, screaming detail — weeks of Qyburn-supervised agony filling the Red Keep, a skull duly sent to Dorne as diplomacy, and a strict official fiction thereafter: Gregor Clegane is dead, and the enormous Ser Robert Strong is an unrelated knight of whom no one is permitted to ask questions, his helm never lifted on the page even once. The show, impatient with the pretense, keeps his name, shows his changed face, and gives the revenant seasons of visible service — Unella's warden, the walk's shadow, the head-crushing of rebellious smallfolk — where book Strong has yet to do anything but stand and terrify. The books also keep his pre-poisoning resume longer: the second Harrenhal occupation, the sack of Saltpans blamed on his dead face's helm, and the full horror of his household's attrition arrive there as testimony the show compresses or cuts. Both versions agree on the essential accounting: Elia, the babe, the brazier, and the bill unpaid.

Their fate — if death has found them, it is written here. Open at your peril.
The show: Ended with his brother in the ruin of the Red Keep (S8·E5)
The Mountain — or the silent thing Qyburn made of him — met his brother on the stair as the Red Keep came down. Blades meant nothing to him anymore; the long fall into wildfire settled what steel couldn't.
How he ends depends on which death you count. In the books he is officially dead already: Oberyn Martell's manticore-envenomed spear killed him by inches in the black cells, his screams administrated by Qyburn, his outsized skull delivered to Dorne to settle a princess's ghost — and the books maintain, with a straight face no reader believes, that the wordless giant serving Cersei thereafter is someone else entirely, his true state a question the published novels have deliberately never answered. The show closes the account in person. As the Red Keep falls, the thing that was Gregor abandons Cersei and Qyburn on the great stair at the sight of his brother — swatting his own maker dead against the stones when Qyburn objects — and meets Sandor in the duel four decades of cruelty had scheduled. He cannot be killed by anything Sandor does: stabbed through the body, blinded in one eye, he simply continues, thumbs seeking his brother's skull in an echo of Oberyn's ending. Sandor's last strength settles it the only available way — a charge that carries them both through the ruined wall and down together into the wildfire-laced inferno consuming the keep. The Mountain dies as he lived, unkillable by rules and killed by his brother's refusal to obey any; the fire that made the Hound unmakes them both, and House Clegane's ledger, opened over a wooden toy, closes in flame.
