Of all the cast members of the Expendables (I to III) , who looked the toughest? If they fought each other in a free-for-all, who would be the victor? Who would be the strongest who could take on all comers. Ok, I know some of them are not that young anymore, but if they were all in their prime, who would win? I'd pick Arnie, he was such a hulking behemoth at his prime, he could have beaten anyone.
