This is an excerpt from theMortalKombat.com website:
Shao Kahn’s Enforcer
Shao Kahn has many warriors under his command, but his trust lies solely in the fighters of his own creation. Warrior blood gathered from countless battlefields, fused with sorcery, produced his most effective enforcer yet: Skarlet.An expert tracker, she preys on those deemed enemies of the empire. During kombat, Skarlet gains strength from her opponent’s blood, absorbing it through her skin. Shao Kahn has a new mission for this formidable kombatant: discover Quan Chi’s true intentions and kill him if he plots betrayal of the emperor.
