hit him in da face

continue to leave the match and challenge him until you are baraka, then use baraka's
foward foward A move / Mutant Blade. Use it over and over again as fast as you can to
keep Scorpion on the ground. You may lose a few times but once you get the feel for it
this is the best / easiest way to defeat him.

if you are in the nexus then keep hitting him up with the sword or if you are really good
karate chop the crap outta his ninja ***
