Inspector Koichi Zenigata relentlessly pursues international criminals for Interpol, dedicating his life to capturing the elusive thief Lupin III. This singular mission began during his tenure with the Tokyo Metropolitan Police, prompting his transfer to Interpol for a global pursuit. A middle-aged Japanese man of average height and muscular build, Zenigata is instantly recognizable by his standard attire: a trench coat, fedora, and suit, with colors varying across adaptations. His signature law enforcement technique involves hurling handcuffs attached to a rope with remarkable accuracy. He sometimes employs firearms like a Colt M1911 or traditional weapons such as a jitte. Zenigata balances stern professionalism with obsessive dedication. Respected within Interpol for his investigative prowess and record of dismantling criminal networks, his fixation on Lupin frequently triggers impulsive actions resulting in comedic chaos. He operates under a strong moral code, rejecting bribes and despising corruption, evolving from earlier, more ruthless portrayals into a principled, albeit eccentric, figure. His personal life remains minimal due to work, marked by messy living spaces and occasional binge eating or drinking during depressive spells linked to failures against Lupin. His defining dynamic is with Lupin III. Despite their adversarial roles, Zenigata harbors a begrudging respect for the thief, considering Lupin his exclusive prey and experiencing genuine grief or loss of purpose when Lupin appears dead. This relationship sometimes shifts into reluctant cooperation against greater threats, underscoring an unspoken mutual regard where neither seeks the other’s demise. Zenigata exhibits near-superhuman resilience when Lupin is involved, rapidly recovering from injuries or sedation—like awakening from a stun gun in seconds. In *Lupin III vs. Detective Conan: The Movie*, Zenigata collaborates with Tokyo law enforcement, including his former police academy classmate Inspector Juzo Megure, to thwart the theft of the Cherry Sapphire. His role expands beyond chasing Lupin to helping resolve a geopolitical conspiracy involving stolen military-grade ore, demonstrating his adaptability in complex investigations. The narrative confirms his established tenacity in pursuing Lupin, tactical ingenuity in setting traps, and endurance during high-stakes confrontations. Zenigata’s background includes familial ties to the historical Japanese detective Heiji Zenigata, though this rarely influences his modern work. Minimal personal history references a failed marriage and daughter mentioned once in *The Mystery of Mamo*, with later series ambiguity suggesting no current family commitments due to his career. Across all media, his character embodies the unwavering pursuit of Lupin, a paradoxical blend of comic futility and steadfast professional integrity.
