It kinda looks like CSZ is "The new king" or like he is possesed by Kahn. Kinda how Baraka becomes the new ruler in MK2 when u win with him. IDK. I thought it looked pretty cool.
You do realize these are just arcade endings, right? Most of these just aren't going to happen, especially Cyber Subby's:
Spoiler:
After Sindel killed him, I guess. Quan Chi now controls him along with many others that died in the story. And also, Shao Kahn was still "alive" when Sindel killed Sub-Zero...
of course they do. they probably had to surrender a portion of their soul to keep smoke human instead of making him a stupid robot. I like the robot characters that are always robots. Don't give me the opportunity to play a cool character then make him into a machine.
