In the 1992 live-action film adaptation, police officer Hazama is killed by the mafia and resurrected as the cyborg 8 Man. His memories are erased, his brain replaced with an electronic one, and he adopts a new appearance. Operating as a private investigator, he possesses superhuman speed and strength, along with the ability to alter his physical form. A critical limitation is his electronic brain's tendency to overheat during exertion, requiring cooling rods resembling cigarettes for regulation. His primary conflicts involve confronting the mafia responsible for his death and navigating a relationship with his former girlfriend, Sachiko, who develops feelings for his new persona. He struggles with his artificial nature and inability to fully reconnect with his past humanity, leaving tensions with his identity and Sachiko unresolved.

The 1993 OVA "8 Man After" presents a different Hazama, a private detective operating years after the original 8 Man's disappearance in a dystopian setting. While investigating a missing person case involving Sam, Hazama is fatally wounded protecting Sachiko (implied to be the same woman from the original 8 Man's life). Merged with the original 8 Man technology, he becomes a new cyborg entity. This version grapples with profound confusion and internal conflict regarding his dual existence as both human and machine, experiencing emotional suppression as a consequence of his cybernetic transformation. His primary adversaries are cybernetically enhanced antagonists threatening the city. The narrative emphasizes his efforts to reconcile his artificial components with residual human emotions, particularly his connection to Sachiko and his protective role toward Sam.
