TV Special
Description
Inspector Koichi Zenigata is a Japanese law enforcement officer with Interpol and the Tokyo Metropolitan Police Department. He descends from the historical crime-fighter Zenigata Heiji, who threw coins as weapons; Zenigata adapted this into his signature handcuff-throwing technique. Early franchise material introduced him as Heiji Zenigata VII before he was renamed Koichi Zenigata. His character embodies a "human Tom and Jerry" dynamic opposite Lupin III, conceived to remain eternally balanced—ending only if both fail, win, or age together.

Physically, Zenigata appears as a middle-aged man of average height with dark hair, a pronounced cleft chin, and varying skin tones across adaptations. He consistently wears a trench coat, suit, and fedora, though colors shift per series: orange in Part 1, camel in Part 2, light green in Part 3, red in Part 4, and light brown in Part 6. Slightly taller and more muscular than Lupin III, this allows occasional disguises between them.

Zenigata’s personality evolves across media. Early manga and Part 1 depict him as corrupt, violent, and opportunistic, though he develops grudging respect for Lupin. By Part 1, Episode 14, he mellows into an affable, comedic figure—energetic and hot-blooded but honorable. He resists bribery, upholds justice, and clashes with corrupt superiors or Interpol’s budget limits. His obsession with capturing Lupin defines his life, causing insomnia, neglected relationships, and refusal to retire. When Lupin appears dead, Zenigata experiences profound grief or loss of purpose, as in *The Fuma Conspiracy* where he briefly becomes a monk. Conversely, he expresses open affection during reunions, sparking jokes about a secret crush he denies.

Professionally, Zenigata began as a Tokyo Police Inspector focused on Fujiko Mine before transferring to Interpol to pursue Lupin globally. Despite frequent failures to capture Lupin, he earns respect for collateral arrests of other criminals. His skills include judo, karate, jitte combat, marksmanship with a Colt M1911 pistol, and near-superhuman endurance—awakening from comas or overcoming injuries at Lupin’s mention. His handcuff-throwing is infallible, though Lupin often escapes. Zenigata operates independently, resigning or investigating off-duty when suspended, as in *Tokyo Crisis* and *Lupin vs. the Clone*.

Personal details are sparse and inconsistent. *The Mystery of Mamo* references a daughter, Toshiko, never revisited. In Part 2, he states he has no family due to his Lupin obsession. He avoids long-term relationships but shows fleeting interest in women like reporter Maria. He eats ravenously (favoring ramen or burgers) when stressed, neglects cleanliness, and binges alcohol during depressive episodes.

In *Goodbye Partner*, Zenigata is arrested for allegedly aiding Lupin, underscoring his unwavering dedication to their cat-and-mouse dynamic. His history includes collaborating with Lupin against greater threats, like protecting Vespania’s crown jewels in *Lupin III vs. Detective Conan*. Their bond follows mutual, unspoken rules: neither kills the other, and Lupin avenges Zenigata if harmed, as in *Island of Assassins*.
