Was playing MK9 on PC doing Shao Kahn's arcade ladder and when I made it to the Shao Kahn boss fight, the Shao Kahn I was fighting was actually wearing a different costume. It was basically just what regular Shao Kahn wore but in light blue. I understand that this is an unfinished character and all that hence why when I press start on him in the character select screen it only selects him instead of letting me pick which alternate costume I want. But the fact that he has an alternate costume at all intrigues me. It might even be further evidence that at a time this character was meant to be playable. I'll probably look into this further ala digging around in the game's files a bit and see if I can find more of his alts or even make them selectable.
