A Wraith, Spectre (sometimes spelled Specter), or Revenant, is a being who has previously died only to be resurrected as an inhuman warrior and/or an evil spirit. Wraiths are not to be confused with the Undead, who are best described as living corpses. These beings wield powers associated with the Netherrealm: shadows and darkness (Noob Saibot) and hellfire (Scorpion).
In Mortal Kombat
The most prominent wraiths are Bi-Han and Hanzo Hasashi. In Mortal Kombat Mythologies: Sub-Zero, Bi-Han had killed Hanzo as the elder Sub-Zero before the first Mortal Kombat tournament. Hanzo was later resurrected as Scorpion and killed him out of revenge, Bi-Han being resurrected as the unholy Noob Saibot, both warriors products of Quan Chi's sorcery.
Smoke may be considered as a type of Wraith as well. In his Mortal Kombat (2011) ending, it was stated he was sacrificed to a demon, and returned to the mortal realm as an Enenra, a creature of smoke and vapor.
In Mortal Kombat X, the souls of the fallen Earthrealm warriors following the Outworld invasion have been claimed by the sorcerer Quan Chi, following a truce between him and the emperor Shao Kahn. These souls have been reincarnated into revenants of the Netherrealm, brainwashed with the sole purpose of serving the fallen Elder God, Shinnok. Only Sub-Zero, Scorpion, and Jax are the known Earthrealm warriors to be revived as humans again.
