MKF30
Fujin and Ermac for MK 11
If I'm not mistaken I believe the scar faded in the 3D games once he used the Dragon Medallion, while it aged him faster it also said to heal him and make him more powerful in the process.In the game, that might be, and probably is, a different Subzero entirely...if it's not Bi Han. In the comic though, that Subzero gets some type of scar at the end of Chap #1, thus is why I think that one is Kuai Liang.
I preface this with saying that NRS has a history of messing around with that scar. You would think that if that was Kuai in MKX that he'd have the scar, but just like in MK Deception, they could take the scar away again for no apparent reason.
But I too think this Sub-Zero is different than the one in the comic hopefully Kuai Liang, or it could be him just changed...who knows lol.
