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.
- Freddy Krueger (Non-canon DLC guest character, Dream Demon)
- Jason Voorhees (Non-canon DLC guest character)
- Noob Saibot (formerly Human in both Timelines, Reborn as Wraith in both Timelines)
- Scorpion (formerly Wraith in the both Timelines, currently Human)
- Jax (formerly in the 2nd Timeline, currently Human)
- Kung Lao
- Liu Kang
- Sub-Zero (formerly Cyborg, then Revenant in 2nd Timeline, currently Human)
- Currently, only four characters are non-traditional Revenants. These characters are Scorpion, Noob Saibot, Jason Voorhees, and Freddy Krueger.
- Scorpion and Noob Saibot are the only known Wraiths created by Quan Chi, while the rest of the characters are Revenants.
- Noob Saibot is also currently the only remaining Wraith created by Quan Chi.
- Freddy and Jason are non-canon and the only Revenants not actually created by Quan Chi.
- Freddy and Jason are also the only Revenants to not reside in the Netherrealm, Freddy being the Dream Realm and Jason being in Earthrealm. However, this is again non-canon.
- Almost all the Revenants created in MK 2011 make cameos in Mortal Kombat X, the only ones not to are Jade and Noob Saibot. However, Noob Saibot is mentioned by Sareena and Jade cameos in Kitana's ending. Neither of them make physical cameos in the game unlikeKabal, Nightwolf, Smoke, and Stryker.
- The only one that the player actually plays against is Sindel, but she only appears in the Story Mode as an NPC.
- Revenants are playable in Mortal Kombat X, these characters being Liu Kang, Kung Lao, and Kitana. Jax and Sub-Zero are also playable as Revenants, but are restored to Human form.
- Kitana is the only Revenant in Mortal Kombat X to not appear in her "human" (Edenian) form in the Story Mode. She only appears in this form in the game's arcade.
- Shinnok is the only other character to be able to create Revenants. The first was Quan Chi.
- Sub-Zero as Cyber Sub-Zero is currently the only Cyborg Revenant to be created, seen in MK 2011.
- Scorpion, Sub-Zero and Jax are currently the only characters who have returned to Human form from being Revenants.
- Scorpion is currently the only Wraith to return to Human form.
- Sub-Zero is currently the only character to change from two different Revenant forms before returning to Human form.
- This is because he was transformed into a Revenant as a Cyborg in MK 2011 then changed into the Revenant form seen in the Story Mode of Mortal Kombat X before being returned to Human form.
- So far, Scorpion is the only character restored to retain some abilities from his Revenant form as a Human (teleportation, Hellfire, etc.)
- The appearance of the Revenants changed entirely from MK 2011 to MKX.
