Yeah, I guess that'd work. But for the Expendables to fight in their own game, there's have to be a top-contender: a Shao Kahn, a Darkseid, an M. Bison.

I mean, if the Watchmen had just their own game, the mastermind behind the plot would obviously be Ozymandias. I don't know who would qualify in Expendables unless we add cast from the sequel then the ultimate rival could be either Jean Vilain, Church, or Trench.
