Here is a strategy video on how to beat Goro as Liu Kang in Mortal Kombat 9. This boss is tough but has a few weaknesses. I've noticed that if you move fast and jump around a lot, you can easily dodge his ranged attacks. Then move in for the hits. Remember you can't throw him, so don't try it. Also stay away from his special (and try blocking it) as it does major damage. Below is the full video of the fight and the win.
