Wraith

A wraith or a spectre (also spelled specter) 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 for Noob Saibot and fire for Scorpion.

The best-known wraiths are Noob Saibot and Scorpion. Noob had killed Scorpion as the elder Sub-Zero, and Scorpion later returned and killed him out of revenge. Sub-Zero then came back as a Wraith. No non-ninja character shares the same species. 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. Freddy Krueger can also be considered a wraith because he was once human and was brought back as an evil spirit by demons.

In Mortal Kombat: Armageddon´s Konquest Mode, Wraiths appear in Shinnok's Spire, summoning Demon Wards and commanding them to attack Taven, so he can't reach the next floor of the Spire.
