Umk3 subzero is a mess...
His umk3 stance is the same as scorpions
While his VS shot is the same as reptiles including reptiles mask.
But his select screen mask is the same as scorpions
His mk1 and 2 go like this,
with the unmasked mk3 subzero too except his palm is closed
Im sure 100% of the fans would like to see subzero maintain his own stance instead of being a messy palette swap of other characters
