Sorry for creating a new thread, but I don't know where to ask this question at.
So I just wonder what the Osh Tekk's real skin color is. In the comics, they seem to have that blueish color what Kotal Kahn does in the game. But in story mode, they have human like skin, so does Kotal in the prequel scene. So which is the real skin and which is the bodypaint or sumthin?

Also it's strange that some characters call the emperor " Ko'atal "...
