lol he has a normal face varient... the subzero without the mask and with a scar across his eye.( technically that is the original subzero's younger brother cus the original dies by the hands of scorpion... and turns into noob) Well for the new mk game they changed it around and the subzero in there does not have the scar.
i dont play enough MK anymore, i guess i would know all that if i did. i would play more but the only game from the series i own is Armageddon... AND IT SUCKS MAJOR BALLS. i do remember seeing a version of him without a mask in deadly alliance (i think?). but i can't remember all that well.
