Who will win the epic battle for Game of Thrones supremacy, Oberyn Martell vs. Gregor Clegane? View Poll »
Size: We think it's safe to say Gregor's got the obvious advantage here. Portrayed by Hafpor Julius Bjornsson, aka the world's second strongest man, Gregor didn't earn the nickname "The Mountain" because he likes to go climbing. No, Bjornsson goes about 6'9", 420 pounds, meaning that Gregor may be the biggest dude Westeros has to offer. If we were in Oberyn's shoes we'd be looking for some medieval HGH about now.
Swordsmanship: Well, he messed up some Lannisters early in season 4, but we haven't really seen Oberyn do much fighting. Not a good sign. Gregor, on the other hand recently disemboweled some peasants with about as much difficulty as if he were shelling pistachios.
