Movie
Description
Inspector Koichi Zenigata, a dedicated Interpol officer, relentlessly pursues the international thief Arsène Lupin III. In *Farewell to Nostradamus*, his chase starts with a diamond heist, escalating onto an airplane where he attempts to apprehend Lupin and Daisuke Jigen. Though Lupin escapes during a hijacking, Zenigata's unwavering focus on bringing him to justice continues throughout the film.

Originating from the *Lupin III* manga and anime, Zenigata serves as Lupin's archrival, conceived as a "human Tom and Jerry" counterpart where neither can achieve permanent victory. Creator Monkey Punch stated any conclusion requires both to end as equals. Zenigata descends from the fictional Japanese detective Heiji Zenigata, known for using coins as weapons. Early iterations named him "Heiji Zenigata VII," but this lineage was deemphasized, renaming him Koichi Zenigata. His true literary counterpart is Inspector Ganimard from Maurice Leblanc's original Arsène Lupin novels.

Physically, Zenigata appears as a middle-aged Japanese man of average height with dark hair, a pronounced cleft chin, and a muscular build slightly taller than Lupin. His iconic attire includes a trench coat, suit, and fedora, with color schemes varying: orange in *Part 1*, camel in *Part 2*, light green in *Part 3*, red in *Part 4*, and similar styles later. This consistent wardrobe ensures recognizability, though designs sometimes reflect narrative contexts, like appearing younger in *Part 4*.

Zenigata's personality balances competence with comedic obsession. Initially portrayed as corrupt, violent, and ruthless in early manga and *Part 1*, he evolved into a more affable yet single-minded character. Respected within Interpol for dismantling other criminal operations, his fixation on Lupin strains relationships with superiors, often causing insubordination or demotions. He maintains a strong moral code, rejecting bribes and displaying old-fashioned honor. His obsession manifests in insomnia, crying when Lupin shows kindness, and continuing pursuits even after suspension or resignation. He shares Lupin’s adaptability in high-pressure situations and occasionally collaborates against greater threats, denying any personal affection.

Professionally, Zenigata demonstrates exceptional skills in hand-to-hand combat (Judo and Karate), marksmanship with his Colt M1911 pistol, and near-superhuman accuracy in throwing handcuffs as a restraining weapon. His physical prowess amplifies during chases, allowing extraordinary feats through subconscious focus. He invents gadgets like specialized handcuffs to outwit Lupin. His investigative acumen includes identifying security flaws and uncovering large-scale conspiracies, as seen exposing a counterfeiting ring in *The Castle of Cagliostro*.

Zenigata’s personal life remains largely unexplored due to his relentless pursuits. *The Mystery of Mamo* references a daughter, Toshiko, otherwise unmentioned. Episodes suggest he desires family but prioritizes capturing Lupin, leaving no time for relationships. Interactions with allies like Fujiko Mine fluctuate; *The Woman Called Fujiko Mine* implies transactional intimacy, while other media depict mutual but wary cooperation. His dynamic with Lupin involves expressing grief when Lupin appears dead yet openly celebrating escapes to prolong their rivalry.

Across adaptations, Zenigata’s character evolves while retaining core traits. Darker interpretations like *The Woman Called Fujiko Mine* revert him to sternness and ambition, contrasting goofier mainstream film depictions. *Part 4* and *Part 5* strike a balance, showing him as serious yet emotionally layered. His development underscores a perpetual cycle of pursuit, embodying the theme that neither he nor Lupin can exist without the other.
