Chief Maltese commands authority as the police chief of the Doggy Police Station. He directly contacts the titular detective to assign cases and request investigative assistance. As head of the police force, he oversees operations and manages resources during major incidents, including serial burglaries, and delegates specific tasks like locating a missing "blue ball" from the lost and found to specialized investigators. He actively participates in law enforcement, collaborating to solve crimes. At public events or exhibitions, he engages attendees, guiding them through investigative processes and evidence collection to recover stolen items such as the "Golden Bubble Milk Tea". His role as police chief remains consistent across all media, including picture books, the anime series, theatrical films, and his appearance in the movie "Farewell My Beloved Partner (Butt)", without significant alterations to his core responsibilities or background.
