TV Special
Description
Inspector Koichi Zenigata began his career with the Tokyo Metropolitan Police before transferring to Interpol to pursue Lupin III globally. His initial characterization depicted a corrupt, opportunistic, and violent officer, possessing only a grudging respect for Lupin as a redeeming quality. This portrayal shifted significantly by the fourteenth episode of the first series, evolving into a more affable and endearingly awkward personality driven by an unwavering sense of justice. He adheres to a strict moral code, refusing bribes and defying corrupt superiors within Interpol. His transient lifestyle, wholly dedicated to the chase, manifests in perpetually messy living and workspaces.

Physically, Zenigata presents as a middle-aged Japanese man of average height (approximately 181 cm or 5'11") with a muscular build, dark hair, and a signature cleft chin. His iconic attire consistently features a trench coat and fedora, though colors vary across adaptations: orange in Part 1, camel in Part 2, light green in Part III, red in Part 4, and light brown in Part 6. This visual design occasionally enables disguise swaps with Lupin due to their similar heights.

Zenigata's existence is defined by his obsessive pursuit of Lupin III, whom he considers his exclusive quarry. He reacts with profound grief or a loss of purpose upon believing Lupin dead, even temporarily retiring to a monastery, while Lupin's escapes instantly reignite his zeal. Despite their adversarial dynamic, Zenigata harbors a complex, unacknowledged bond with Lupin, sometimes collaborating against greater threats and demonstrating protectiveness—insisting only he may apprehend Lupin. This mutual respect surfaces when Lupin avenges Zenigata's apparent death.

His investigative skills are often underestimated. Zenigata exhibits exceptional deductive abilities, predicting Lupin's strategies and inventing specialized devices like inescapable "Zenigetcha" thumb cuffs or Lupin-detecting machinery. In combat, he utilizes judo, karate, a jitte, and his signature handcuff-throwing technique with near-superhuman accuracy. His endurance is legendary; he once revived from a shock capable of incapacitating an elephant within 30 seconds simply upon hearing Lupin's name, showcasing his tenacity and subconscious physical prowess during pursuits.

Personal details remain inconsistent across media. Early installments referenced a daughter, Toshiko, and marital strain, though later episodes denied any family. *The Woman Called Fujiko Mine* depicted a backstory involving corruption and adopting an orphan, Oscar, contrasting his typical incorruptible portrayal. His solitary existence, devoid of lasting relationships, is attributed to his all-consuming mission.

Recent expansions to the character include a 2017 live-action series focusing on his police work in Japan and the upcoming animated film *Lupin the IIIRD: Zenigata and the Two Lupins*, where he investigates Lupin's alleged involvement in an explosion amid a case of mistaken identity. Zenigata also stars as the protagonist in multiple pachislot games.
