The Mountain — Glenn Jacobs
Ser Gregor Clegane (also known as ?The Mountain?) is undoubtedly the most intimidating person in Game of Thrones. The hulking behemoth combines enormous size with a nasty attitude. He burned his brother’s face when they were children, and it created a rivalry that lasted throughout each sibling’s lifetime.
Although Jacobs’ character in the WWE was the one that is supposed to be burnt, the man who formerly performed as WWE superstar Kane would be a perfect fit for this role. He’s adept at working with a mask on and is able to convey emotions, thoughts and feelings without ever speaking a word.
