Ninja Batman

At Arkham Asylum, Batman clashes with Gorilla Grodd while trying to destroy Grodd's newest invention: the Quake Engine. Amidst the chaos, the engine activates, and the entire asylum suddenly vanishes into thin air—Batman along with it. Once the dust settles, Batman finds himself standing in the middle of an unfamiliar road. He soon realizes that he is no longer in Gotham City—but instead in Feudal Japan! The amazement quickly fades as samurai descend upon him, seeking to take his life. Later on, Batman's investigation leads him to discover that the one responsible for the kill order is none other than his archnemesis, the Joker. Following an encounter with Catwoman, he learns that the asylum's criminals had teleported there two years earlier—each ruling over a piece of Japan with Joker being the dominant warlord. In order to return home, Batman must reactivate the Quake Engine, situated in the remnants of the asylum, now known as Arkham Castle. However, there is one problem: aside from his gadget belt, the arsenal that was once at his fingertips is all but gone. Ninja Batman follows the Dark Knight as he traverses a strange new environment, facing off against familiar foes in a bid to return to Gotham in one piece. Batman Ninja takes a journey across the ages as Gorilla Grodd's time displacement machine transports many of Batman's worst enemies to feudal Japan—along with the Dark Knight and a few of his allies. The villains take over the forms of the feudal lords that rule the divided land, with the Joker taking the lead among the warring factions. As his traditional high-tech weaponry is exhausted almost immediately, Batman must rely on his intellect and his allies—including Catwoman and the extended Bat-family—to restore order to the land, and return to present-day Gotham City.
