An English-dubbed trailer for the Batman Ninja anime film released online via Warner Bros. Home Entertainment. The trailer was accompanied by the announcement that the film will release on Digital on April 24, 2018, followed by a Blu-Ray and DVD release on May 8.

According to the trailer description, “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.”

The English voice cast includes Roger Craig Smith as Batman, Tony Hale as the Joker, Grey Griffin as Catwoman, Tara Strong as Harley Quinn and Poison Ivy, Fred Tatasciore as Gorilla Grodd and Deathstroke, Yuri Lowenthal as Robin, Adam Croasdell as Nightwing and Alfred, Will Friedle as Red Robin and Red Hood, Tomy Kenny as Penguin, and Eric Bauza as Two-Face.
