so I guess to make sense of it all, Kuai (Codename Tundra) is the younger brother of original Sub Zero aka Bi-Han. After Sub Zero (Bi-Han) was killed by Scorpion in the tournament he was resurrected as a wraith shadow being Codenamed: Noob Saibot. While Tundra, his younger brother took on Bi-Hans codename Sub Zero for himself to honor his death.

So original Sub Zero in the older MK is Bi-Han Now he is wraith shadow being codenamed Noob Saibot

and the Sub Zero you see now is Tundra, the younger brother of Bi-Han who is now a shadow wraith.

Now we can make sense of this, its pretty cool.
