In the end, of course, there could be only one. Everyone knows the best way to determine relative badassity is to pit the two in question against each other in a fight to the finish. Our winner Edward LaRusic has done this, and shown enough economy of style in his recounting of the fight that one might consider the man something of a badass himself. Solid Snake lights a cigarette, Ashley cleans the blood off his blade. Ashley charges with all his fury.
Snake hides in a box.
Ashley gets confused as he wonders where Snake went. Both Snake and Callo light a cigarette. You try crawling through ventilation ducts and come out smelling like roses Solid Snake is the most obvious bad ass because his ass stinks. His ass defines bad. There is no good in Snake's ass at all.
