Oni

Oni is a term taken from Japanese folklore, which in the Mortal Kombat world seems to just be a generic word to describe all the demons of the Netherealm. They are first seen as nothing more than glowing yellow eyes in Goro's Lair in the original Mortal Kombat. In Mortal Kombat: Deception, they are depicted as hideous creatures with sharp claws, wild hair, and two long horns growing from their heads, but are humanoid for the most part. Still others inMortal Kombat: Shaolin Monks are shown as apelike and burly creatures, with glowing eyes similar to Moloch's. They are all said to roam the Netherealm in search of damned souls to torment for their own personal pleasure. After making their way to Outworld, they were said to have been seen hiding in the Living Forest, consuming those who entered. The only well-known, playable Oni are Drahmin, Moloch, and Quan Chi. Belokk was also believed to be an Oni, but he was scrapped prior to Mortal Kombat Gold and was never featured in any game.
