TV Special
Description
Inspector Koichi Zenigata operates as Lupin III's chief law enforcement adversary throughout all media. As an Interpol agent, he dedicates his career to capturing Lupin, frequently elevating this pursuit above other responsibilities and personal matters. His background originates in Japanese policing before transferring to Interpol for international pursuit of the thief.

Zenigata possesses remarkable physical prowess, excelling in judo, karate, and marksmanship with a Colt .45 pistol. His signature move involves throwing handcuffs in a bola-like arc to immobilize targets, enabling intense physical confrontations during chases. Visually, he consistently wears a trench coat and fedora across productions, with variations maintaining core features like his distinctive chin and sturdy build.

Personality-wise, Zenigata displays obsessive dedication to apprehending Lupin, often manifesting comedic desperation. Despite their rivalry, an underlying mutual respect persists: Zenigata prevents others from capturing or killing Lupin, while Lupin occasionally rescues or avenges him. They form temporary alliances against greater threats, such as exposing Count Cagliostro's counterfeiting or surviving castle catacombs together. When believing Lupin dead, Zenigata faces profound loss of purpose, even retiring as a monk in The Fuma Conspiracy.

Early depictions presented Zenigata as more ruthless, but he evolved into a sympathetic figure with comedic traits. He maintains professional competence, earning respect for collateral arrests during Lupin pursuits despite repeated failures to catch the thief. Zenigata exhibits emotional vulnerability, weeping during poignant moments involving Lupin. His personal life remains largely unexplored, though The Mystery of Mamo briefly references a daughter, and later media imply familial neglect due to his obsession.

In *Dragon of Doom*, Zenigata participates in recovering a dragon statue from the Titanic. His broader characterization includes resistance to corruption, disorganized personal habits, and impulsive actions driven by strong traditional values. Across the franchise, his core traits endure while adjusting tone between serious and comedic interpretations per production.
