In the parody anime DD Fist of the North Star, which reimagines the characters of the original series in a peaceful, modern-day Japan, Bat is depicted as a university student. He works part-time at a convenience store named Ryuryuken, which is owned by the character Ryuken and also employs Ryuken's daughter, Rin.

Unlike the post-apocalyptic wasteland of the original story, this version of Bat is an ordinary young man living in a peaceful world. His personality serves as a contrast to the other main characters. While Kenshiro, Raoh, and Toki inflexibly cling to their original, larger-than-life martial arts personas, causing trouble and accidents, Bat possesses a more normal and modern mindset. As a result, he often finds himself suffering as the straight man, getting caught up in the ridiculous situations caused by the Hokuto brothers. His relationship with Rin is retained, but it is re-contextualized; here she is his coworker and the daughter of his boss, rather than a fellow survivor he protects.

Bat's role in the story is primarily that of a grounded observer and participant in the comedic, slice-of-life events that unfold around the convenience store and the fictional town of Asaenji. His development is less about heroic growth and more about navigating the absurdity of his daily life alongside these iconic characters. In terms of abilities and notable traits, his defining characteristic in this parody series is his normalcy. He lacks the superhuman martial arts skills of the Hokuto brothers and instead reacts to their antics with a relatable, often exasperated, common sense. Visually, the series often draws him with more standard, less deformed proportions compared to the two-headed SD (super deformed) style used for Kenshiro and the others, further emphasizing his role as the relatively normal character in a world of exaggerated parodies.
