In regards to the mask thing... Despite the MKX mask bearing very little resemblance to MK9 Bi Han's mask, you can't dispute that MKX Sub's 'Unbreakable' variation mask is pretty much exactly Kuai's mask but frozen over.
Still though.. Kuai was in his brother's garb anyhow. So who knows. IMO don't look too far into the mask.
I agree as far as the mask in Unbreakable goes, but the "Cryomancer" and "Grandmaster" masks have more of a Bi-Han look to them, IMO.
You can be convinced but we won't know for sure until we know for sure.
I would hate it if each variation was a different Sub-Zero. Atleast in MK9, Bi Han and Kuai had different uniforms.
Yes, I've read that already, it does seem like a possibility.. among others.
Granted, but my point is that this new evidence leans more toward it being Bi-Han.
Whether it is or not is something that we'll have to wait and see.
If Cassie Cage can have 2 variations which are named as a nod to her parents, I don't see why Sub-Zero can't have 1 variation being a nod to Bi-Han, 1 variation being a nod to Kuai-Liang and 1 variation being MKX Sub-Zero.
Each variation DOES have a unique costume trait to it.
Cryomancer has frozen arms.
Unbreakable has the frozen mask.
Grandmaster has the Dragon Medallion.
