Noob saibot - China
Subzero - China
On the contrary...the long-defunct official website for Mortal Kombat Mythologies: Sub-Zero (which is still accessable via web.archive.org) states that both Kuai Liang AND Bi-Han (along with an unnamed sister) were born in the United States. Sub-Zero and Noob Saibot are both American, and that is both canon and final.
I understand, for example my ethnicity and my whole family's is palestinian but as far as my ID/passport tells me my nationality is jordanian, all I'm saying that if they had a ID card it would probably say nationality: chinese.
I'm sorry I don't follow. You do know nationality includes ethnicity?
