10 Game Of Thrones Warriors Who Could Defeat The Mountain

2. Barristan Selmy

"I am a knight! I shall die a knight!"

Barristan Selmy was not only the archetypal knight, but also the most skilled and revered in all of the Seven Kingdoms. Of the many mistakes made during the reign of Joffrey Batatheon, dismissing Ser Barristan Selmy from the Kingsguard was doubtless one of the greatest (ranked just below having that sip of wine).

Barristan Selmy€™'s experience not only lends itself to invaluable counsel, but he was still the best warrior Joffrey had at his disposal, despite his comparatively old age. In disrespecting Selmy, Joffrey personally handed Daenerys Targaryen one of her most valuable assets.

Were he to fight Gregor Clegane in his prime, Selmy€™'s skill and mastery of tactics, combined with the strength and speed of his youth, would mean that he would easily best the larger man.

As per the books, Barristan entered a tourney disguised as a knight and jousted with Targaryen royalty aged only ten. Since this point, Barristan Selmy established a reputation as being one of the greatest knights in the history of Westeros, both in the heat of battlefield and in tourneys. Even after having fought for the losing side, Robert Baratheon spared the life of Selmy in virtue of his legendary skill and honour as a knight. Hulking brutes like The Mountain come and go in Westeros, but a warrior of Barristan Selmy€™'s calibre comes once in a lifetime.
