ser gregor clegane is the head of house clegane, a landed knight vassal to house lannister, and is the older brother of sandor clegane. his enormous size and strength make him a fearsome warrior (in the novels he is nearly 8 feet tall, and weighs over 400 lbs.), and he has earned a reputation for violence and brutality. when they were children, gregor shoved sandor's face into a brazier for using his toy, gruesomely scarring him. over the course of his service to tywin lannister, he has committed numerous war crimes, most infamously the rape and murder of the targaryen royal family, but has repeatedly avoided punishment due to house lannister's power and influence over the iron throne. clegane was one of the first lannister soldiers to enter king's landing during its sack at the end of robert baratheon's rebellion. he raped and murdered princess elia, after murdering her son aegon by shattering the child's head against a wall, a grudge house martell still bears 14 years later at the onset of "a game of thrones".
