The Netherrealm has produced many vile beings, but none rival the Arch-Sorcerer Quan Chi. In lieu of Netherrealm demons, he prefers to resurrect deceased warriors for use in his sinister plans. Foremost among them is the tortured Shirai Ryu ninja Scorpion, who is Quan Chi's personal assassin. Quan Chi is building an army of such specters--the purpose of which has yet to be revealed. Another mystery is the sorcerer's involvement in the Mortal Kombat tournament. The Netherrealm has no stake in its outcome, which leads some observers to question his presence....

Having finally brought about Shao Kahn's demise, Quan Chi was then tasked with growing the ranks of the Brotherhood of Shadow.
Many warriors had perished in Outworld's invasion of Earthrealm. Quan Chi stole their souls and remade them to serve his master, the fallen Elder God.
The task completed, Shinnok repaid Quan Chi's service by ordering his execution, thereby eliminating a possible challenger to his rule.
Quan Chi had anticipated this act of treachery, however, and resurrected Shao Kahn--the ultimate phantom warrior.
With Shao Kahn as his enforcer, Quan Chi struck down the Brotherhood of Shadow and Shinnok. Quan Chi forgives betrayal from no one. Not even a god.
