The Face of Kun-Lo is a strange ancient facemask used and worn by the Oni named Drahmin. Not much is known about it or where it originated from. It first appeared along with him in Mortal Kombat: Deadly Alliance.
About the Face of Kun-LoEditThis strange, demonic mask allows Drahmin to focus his power into a precise lethal fighting style, earning him the title of the legendary Oni-Tormentor.
It should also be noted, that this may be the reason why Drahmin has a much more "humanoid," appearance as compared to other Oni.
