Hanpei Hattori appears in the 2014 film Kikaider Reboot as a character whose profession and approach differ from his portrayals in other iterations of the franchise. Rather than being a private detective, this version of Hanpei Hattori is a cell phone novelist who also works as a net journalist and report writer. His journalistic skills are noted to be not particularly strong, but he possesses a strong sense of justice that drives his actions.

Hanpei Hattori becomes involved with the central conflict by approaching Mitsuko Komyoji. His motivation is to uncover the truth behind the death of her father, Dr. Komyoji. This investigative drive leads him to dig into the shadowy aspects of the ARK project, a significant undertaking that reveals his capability to find information about hidden conspiracies despite his shortcomings as a journalist. He plays a role in helping to expose the darkness connected to the project, aligning himself with the search for answers about the androids and the circumstances surrounding their creation. His abilities lie not in physical combat or detective work in the traditional sense, but in his skills as a researcher and writer, using his craft to investigate a powerful and secretive organization.
