Ser Gregor Clegane, otherwise known as “The Mountain,” has been resurrected on Game of Thrones and his face is worse for wear. Widely known for his impending size and brute strength, he was killed with a venomous spear by Oberyn Martell.
Don’t worry, he got his revenge, shattering Oberyn’s skull in his palm right before he died.
In the season finale, he made his return from the dead, and we got a chance to peek under his helmet to see his decomposing flesh. This is the stuff nightmares are made of!
