Sin Tzu, the Warlord of Asia, had become an unsurpassed strategist and warrior in his Asian homeland. His mastery of Yan Jing, the metaphysical art of manipulating mental energy, grants him the ability to affect the minds of both his allies as well as his opponents, making him practically unstoppable. After a long-lived reign of terror across Asia, he became disinterested in warfare and battles, as there was no great challenge left to overcome; no adversary worthy of his attentions. And then he began to hear the legends of Gotham City. The famous and notorious urban-legend, the dark knight detective: the Batman. Possibly the one perfect foe for Sin Tzu to test his mettle against. Tzu arranges for himself to be taken to Arkham Asylum. There, he slowly and carefully assembles an army with which to take on the dark superhero: Scarecrow, Clayface and Bane. At midnight, the battle begins. With his own army of himself, Nightwing, Robin, and Batgirl, the Batman will have to outsmart, overpower, and overcome a new villain, a new power, a new evil; unlike any he has ever faced before.

Sin Tzu:
The art of war is deceit. First, you must strike when your opponent least expects; in a place where he feels strong, but is in fact weak; with an army he believes he has already vanquished.
