Transported back to feudal Japan during an Arkham Asylum confrontation alongside Nightwing, Red Hood, and Robin, Tim Drake operates as Red Robin in "Batman Ninja". He allies with Batman, Catwoman, and Alfred Pennyworth in this historical setting to combat Lord Joker and other Gotham villains transformed into feudal lords. As part of the Bat-Family, Red Robin collaborates with the Bat Clan of Hida, a group venerating Batman as a deity. He participates in strategic battles against these adversaries, wielding his signature bo staff and applying his expertise in detective work and combat tactics. The conflict culminates in a large-scale battle where Red Robin contributes to forming the "Batgod," a giant samurai entity created by merging the Bat Clan's forces with an army of bats. This effort helps secure victory over the merged castle robot "Lord Joker" before the heroes return to present-day Gotham.
