Suggested by IKnowledge Gregor Clegane is one of the strongest characters in the Game of Thrones series. His physical abilities were already considerable from the start, but he has been amped up recently so that he can crush a person with his bare hands. He also wears very thick armor which protects him from most attacks. Beatrix Kiddo is just out of her league here. She can certainly outfight him since Gregor isn’t the most technical of fighters, but dealing damage to him will be very difficult. He also just needs one hit to end the fight and there’s a good chance that he will land this blow. Gregor Clegane wins.
