I found this.

(It is unconfirmed which Sub-Zero features in the game. Histories follow for both characters).


The original Sub-Zero, Bi-Han, attended the Mortal Kombat tournament for the Lin Kuei. Scorpion killed him in the Netherrealm, believing him to be responsible for the death of Scorpion's family and clan.
Quan-Chi revived him as his servant, Noob Saibot. Noob Saibot was kicked into a soulnado during the invasion of Earthrealm, leaving his fate unknown.
Sub Zero's brother, Kuai Liang, then assumed the position of Sub-Zero to avenge the death of this brother at the hands of Scorpion, who tore out his spine during Shang Tsung's Mortal Kombat tournament.
Sub-Zero was taken captive by the Lin Kuei just after he had beaten Scorpion during Shao Kahn's tournament, and he was automated, turning him into a cyborg. Initially evil, he soon overcame his programming and returned to his normal state of mind to aid his fellow Earthrealm warriors. Sindel kills him during the invasion with an uppercut.

It's unclear how Sub-Zero was revived and reverted back to his human form since the last Mortal Kombat event, which took place 25 years prior to Mortal Kombat X.

My two cents on this^

It's unconfirmed which Sub-Zero it is, but, yet they say it's unclear how Sub-Zero was reverted back to his human form.
So I think it's clear that this Sub-Zero is in fact Kuai Liang.

What a brilliant example of logic.


Sometimes it starts to look like it. On the other hand amount of idiotic complaints is just hilarious and stupid too much to ignore.
But anyway, what I do with my time, I'll figure on my own.


I smell a butthurt.
So, attempts to stop stupid and pathtic hatred are "incoherent ramblings" now. Oh, wow. I am not prick on purpose to the normal people. But it seems you want to be excluded from their list...be my guest. Not big loss for anyone.


Another butthurt boysprout.
Gee. what is it? Hemorhoids epidemic?
