Transported to feudal Japan by Gorilla Grodd's time displacement device, the Gotham City villain Dos Caras (Two-Face) adapts to the setting and rises to power as a feudal lord, engaging in the power struggles among Gotham's displaced villains. He forms an initial alliance with Gorilla Grodd, leveraging it to advance his own objectives. This partnership culminates in betrayal during a river confrontation; Grodd reveals their collaboration after temporarily defeating the Joker and Harley Quinn while Batman remains incapacitated.

Dos Caras contributes a vital power converter essential for operating the Quake Engine time machine. This component is one of several required by Catwoman and Grodd for their return to present-day Gotham, forcing them to seek others from fellow villains. Later, he joins the large-scale mobilization of castle robots at the "Field of Hell," participating in the climactic battle alongside other antagonists. Following the defeat of several villains, Grodd attempts to seize control through mind manipulation. The Joker and Harley Quinn disrupt this plan, leading to the formation of a combined super robot. Dos Caras is ultimately defeated alongside the other villains and returned to the present day by the Bat-Family.
