In feudal Japan, this incarnation adapts as a daimyo, establishing power within a mechanized castle. The castle's interior mimics a glacier, creating a cold environment that mirrors his preference for familiar surroundings and offers psychological comfort. This design serves a practical purpose while reinforcing his aristocratic sensibilities in the new era.

He adopts the trappings of Japanese aristocracy, wearing traditional attire befitting his status as a feudal lord. His strategy involves forging alliances with other displaced Gotham villains, engaging in their conflicts over territorial dominance across the war-torn landscape. This collaboration culminates in a large-scale confrontation at the "Field of Hell," where he mobilizes his forces alongside the other villains.

His methods leverage the advanced technology of his castle fortress, capable of transformation and integration with other structures. During the climactic battle, his mechanized castle combines with those of the other villains to form the composite super robot "Lord Joker" under the Joker's control. This integration showcases his technological resources and role within the collective villain effort.
