AKA: Ser Gregor Clegane Going by the 8-foot-tall version in the books I'll start... Oberyn Martell (due to his fighting style. I don't think he could take Jaime or Ser Barristan Selmy in their prime) Robert Baratheon in his prime (maybe) Sandor Clegane - The Hound (maybe) People Who I would bet against (I'll go through all the great fighters of the known world): Ser Jaime Lannister Ser Barristan Selmy (in his prime) Ser Bronn of the Blackwater Eddard Stark Rhaegar Targaryen Jon Snow Khal Drogo what do you think? edit: in case of confusion, i'm going by the characters shown in the show. so no arthur dayne.
