Batman Ninja, ニンジャバットマン

Batman embarks on a mission through different eras with Grodd's device that transports his enemies from modern Gotham City to feudal Japan. These foes assume the identities of powerful lords in the warring factions of Japan. With his high-tech weapons depleted, Batman must use his wit and allies such as Catwoman and his extended family to restore peace in Japan and return home to Gotham City.
