You know it's coming when you watch them kung fu/ninja movies, and sometimes the way the plot gets you to it is crap, but what the hell, it gets you there anyway.
IT'S THE BIG CLIMACTIC BATTLE! It's good ninja vs bad ninja, it's the good student vs evil fellow student, it's the bereaved disciple vs his master's killer. So without further ado, I bring you Snake Eyes vs Storm Shadow!
