I got this info on mksectrets...

You probably remember the exclusive Skab render, that Mortal Kombat Secrets provided two weeks ago. Unfortunatelly the information in the Official German PlayStation 2 magazine has been wrong and this was not Skab. The warrior on the render is actually Noob Saibot and one of his alternative outfits. We, here at MKSecrets are very disappointed with this magazine and the wrong information they provided.

It is still unknown if this Skab even exist and if he exist what he looks like, because obviously he will not look the way he was described in the magazine:

Skab is the most disgusting fighter of all. If you take a closer look you will see parts from his rotting corpse and a skeleton.
