Quan Chi had allegedly been granted the souls of the fallen earthrealm warriors or those of the emperors unwilling servants (Hence explaining why Sindel was amongst those Quan Chi resurrected but Shang Tsung and Motaro were not). In Mortal Kombat: Armageddon's Konquest Mode, Wraiths appear in Shinnok's Spire, summoning Demon Wards and commanding them to attack Taven to prevent him from reaching the next floor of the Spire. 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. Smoke may be considered as a type of Wraith as well. Hanzo was later resurrected as Scorpion and killed him out of revenge, Bi-Han being resurrected as the unholy Noob Saibot, both warriors being products of Quan Chi's sorcery.
In Mortal Kombat Mythologies: Sub-Zero, Bi-Han had killed Hanzo as the elder Sub-Zero before the first Mortal Kombat tournament. The most prominent wraiths are Bi-Han and Hanzo Hasashi.
