Description
Inspector Koichi Zenigata is a central figure in the Lupin III franchise, relentlessly pursuing the titular thief as his primary antagonist. His character displays significant development across different media interpretations.

A descendant of the fictional detective Zenigata Heiji, known for using coins as weapons, Zenigata adapts this legacy into his signature handcuff-throwing technique. Originally introduced as Heiji Zenigata VII, his name was later standardized. He originates from Japan, transferring from the Tokyo Metropolitan Police Department to Interpol to focus internationally on capturing Lupin III, making this pursuit his life's mission.

Physically, Zenigata is a muscular, square-jawed man of average height (approximately 5'10" or 181 cm) with dark hair typically styled in a flat-top or comb-over. His most recognizable feature is his trench coat, varying in color: orange in Part 1, camel in Part 2, light green in Part 3, red in Part 4, light brown in Part 6, and camel in the film *The First*. His build resembles Lupin's, aiding in disguises between them. Early designs depicted him with darker, red-toned skin, which lightened in later versions.

Zenigata balances competence with comedic obsession. While often portrayed as single-minded or bumbling in his pursuit, he is a highly skilled detective capable of uncovering security flaws and arresting numerous criminals. He embodies a strong sense of justice, refusing bribes and condemning corruption. His obsession manifests in insomnia triggered by Lupin's name, neglect of personal hygiene, and existential crises when believing Lupin dead, leading to temporary retirement in *The Fuma Conspiracy*. Despite their rivalry, he holds a grudging respect for Lupin, forming temporary alliances against greater threats, like exposing a counterfeiting operation in *The Castle of Cagliostro*. He is emotionally expressive, often crying when Lupin shows kindness or appears in mortal danger.

His skills include proficiency in judo and karate, marksmanship with a Colt M1911 pistol, and exceptional endurance, allowing rapid recovery from injuries or sedatives when Lupin is involved. His signature weapon is handcuffs attached to a long rope, thrown with precision. He operates with a "cowboy cop" mentality, frequently disregarding protocol or budgets, straining relations with Interpol superiors.

Zenigata's character evolves significantly. Early manga and *Part 1* portray him as ruthless, violent, and occasionally corrupt. By *Part 1*'s 14th episode, he mellows into a more affable, though hot-tempered, figure. *The Woman Called Fujiko Mine* revisits darker traits, showing ambition and willingness to exchange favors. Modern series like *Part 4* and *Part 5* present a balanced version: serious yet prone to outbursts, exploring his pride (*Part 5*, Episode 4) and amnesia-induced thievery (*Part 5*, Episode 20). The live-action series *Inspector Zenigata* (2017) depicts him as a dedicated, hard-boiled cop focusing on investigations beyond Lupin.

His dynamic with Lupin is complex, marked by mutual obsession and unspoken rules. Lupin affectionately calls him "Pops" or "Tottsan," and Zenigata insists only he can arrest Lupin. Creator Monkey Punch described their relationship as a "human Tom and Jerry" dynamic, stating any ending would require them to "end as equals—both fail, both win, or both get very old."
