Suggested by IKnowledge Gregor Clegane is back and he is up against another swordswoman. Lyn is one of the quickest sword fighters out there though and she will be able to exploit his weaknesses. Gregor Clegane may have some decent speed considering his size, but he isn’t very nimble. Gregor also isn’t a great swordsman as he purely relies on power. Lyn will be able to evade and parry quite easily as she hits him with lethal sword strikes. There’s no way his armor can stop her sword swings since it was created to slay large monsters. Gregor simply won’t be able to stop her. Lyn wins.
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.
