TV Special
Description
Inspector Koichi Zenigata, originating from Japanese law enforcement, served with the Tokyo Metropolitan Police before transferring to Interpol to devote himself entirely to apprehending Lupin III. His relentless pursuit ignited in New York during an investigation involving Fujiko Mine, evolving into a lifelong obsession. Zenigata is depicted as a descendant of the historical detective Zenigata Heiji, though later series iterations lessened this bloodline's focus. Conceived as Lupin's human counterpart in an eternally balanced "Tom and Jerry" dynamic, their rivalry was designed to conclude only if both aged, succeeded, or failed together.

His personality shifts significantly across media. Early portrayals, particularly in *Lupin the 3rd Part 1* and the original manga, show him as ruthless, corruptible, and violently obsessive, willing to shoot Lupin. This characterization softened in *Part 1*'s later episodes towards a more affable, boisterous, and comically earnest figure, while retaining his single-minded dedication. *The Woman Called Fujiko Mine* and related spinoffs revert to a sterner, ambitious, and occasionally corrupt demeanor, including accepting sexual favors from Fujiko. Later series like *Part 4* and *Part 5* blend seriousness with moments of goofiness, reducing overt bumbling. Core traits include an unwavering sense of justice, resistance to bribery, impulsive honor-driven reactions, and emotional vulnerability—often crying when Lupin shows kindness or appears dead. If Lupin is believed deceased, Zenigata may retire or isolate himself, exemplified in *The Fuma Conspiracy* where he becomes a monk praying for Lupin's reincarnation as law-abiding.

In *Tokyo Crisis*, Zenigata's determination and moral code are highlighted while investigating Michael Suzuki's corruption. After Suzuki's operatives cause chaos during a transport, Interpol suspends Zenigata for the public disruption. Despite losing his badge, gun, and handcuffs, he investigates independently, demonstrating commitment beyond institutional authority. His persistence uncovers Suzuki's genetic engineering schemes, leading to reluctant collaboration with Lupin to protect journalist Mariya and expose Suzuki. During this alliance, Zenigata exhibits vulnerability, confiding suspicions to Mariya and drinking heavily due to suspension frustration. His dynamic with Mariya reveals a paternal side as he empathizes with her traumatic past and prioritizes her safety.

Physically, Zenigata is a middle-aged Japanese man of average height and muscular build, typically wearing a trench coat, fedora, and suit. His appearance varies slightly, with younger depictions in *Part 4*. He possesses exceptional physical prowess, proficient in judo, karate, and jitte combat, performing near-superhuman feats during chases—like scaling obstacles or defeating groups subconsciously while fixated on Lupin. His signature weapons are a Colt .45 pistol and handcuffs thrown with bola-like precision. He avoids smoking or excessive drinking but binges during depressive episodes, as after his suspension in *Tokyo Crisis*. His personal life is minimal; references to a daughter (*The Mystery of Mamo*) remain unexplored, and his Lupin obsession precludes long-term relationships, though he occasionally expresses loneliness.

Zenigata's relationship with Lupin is complex and mutually respectful. An unspoken rule forbids lethal force between them. Lupin openly treats Zenigata as a friend, while Zenigata denies affection yet shows profound grief when Lupin seems dead and vindictive rage towards his harmers. Zenigata believes only he deserves to capture Lupin, and Lupin reciprocates by avenging Zenigata when others target him. This dynamic includes reluctant alliances against greater threats, as in *Tokyo Crisis* and *The Castle of Cagliostro*, where Zenigata's professionalism and hidden kindness emerge. Interpol tolerates his Lupin-focused missions due to the high volume of unrelated criminals apprehended incidentally during his pursuits.
