Two-Face appears as a supporting villain transported from modern Gotham City to feudal Japan alongside other Batman foes. Adapting to this new era, he establishes himself as a regional warlord operating under the overarching rule of the Joker, who controls feudal Japan. Within this structure, he commands his own forces and resources.

His appearance retains the classic duality motif fused with Japanese feudal elements. The disfigured half of his face remains distinct, while his attire blends traditional two-toned suits with period-appropriate armor and garments. His weaponry includes conventional firearms alongside adapted weapons like katanas. His signature coin-flipping ritual persists as his primary decision-making method.

Demonstrating opportunism, Two-Face initially aligns with Gorilla Grodd during a pivotal river battle against Batman and the Joker, coordinating their forces. He later participates in Grodd's attempt to control the other villains at the gathering on the "Field of Hell."

In the climactic conflict, Two-Face contributes his castle. It physically merges with others to form the massive battle robot "Lord Joker," intended to destroy Batman and his allies. Following the robot's destruction and the villains' defeat, he is returned to present-day Gotham City and taken into custody by Police Commissioner James Gordon. His role concludes with this capture. He does not appear in a subsequent story involving an invasion by the Yakuza League. Specific dialogue, detailed interactions beyond strategic alliances, and further exploration of his psychological state within this continuity remain unexplored.
