Batman Ninja

Batman battles Gorilla Grodd in Arkham Asylum, attempting to stop Grodd's latest creation, the Quake Engine. In the midst of the fight, the engine activates, causing the entire asylum-and Batman-to disappear. When the chaos clears, Batman stands on an unknown road, realizing he’s no longer in Gotham but in feudal Japan. His shock is short-lived as samurai attack, intent on killing him. Through his investigation, Batman discovers the Joker is behind the assassination order. After crossing paths with Catwoman, he learns that the asylum’s inmates arrived two years earlier, each carving out their own territories-with the Joker reigning as the most powerful warlord. To get back to Gotham, Batman must restart the Quake Engine, now housed in what remains of the asylum, renamed Arkham Castle. But he faces a major obstacle: aside from his utility belt, he’s lost most of his gear. Now, as "Ninja Batman," he must navigate this unfamiliar world, fighting old enemies in a desperate race to return home alive.
