Koichi Zenigata

Inspector Zenigata (銭形警部 Zenigata-keibu), full name Kōichi Zenigata (銭形 幸一 Zenigata Kōichi) is the supporting character of Lupin III. He is an incredibly talented, yet often bumbling police officer who has made it his life's goal to capture Lupin III.

Appearance
Zenigata is often portrayed as a middle-aged man of average height. He has dark hair, typical of the average Japanese man although in Plot of the Fuma Clan, he had shaved his head when he joined a monastary. Depending on the occasion, the Inspector will either have his hair cropped into a flat-top or neatly styled into a combover. Zenigata is always seen wearing his signature khaki colored trench coat over a dark brown suit and a stereotypical Inspector's fedora. As with the rest of the characters, the color scheme of his attire slightly changes from series to series.

Personality
Throughout the franchise, he has been portrayed as both a serious and competent police inspector and a bumbling, overzealous cop. Although every incarnation of him has both of these qualities, the level of seriousness and incompetence varies. In the Green Jacket and Fujiko Mine Series, he is portrayed as more stern, whereas in the Red and Pink series as well as a majority of the TV specials and movies, he is much more goofy.

Zenigata is widely respected among his fellow officers at Interpol as an expert criminal catcher. He was able to discover security flaws and took down countless gangs and criminals long before he met Lupin.

Zenigata tends to be impulsive. This is probably due to his strong sense of justice and honor which others often consider old fashioned. Unlike most other officers in the police force and Interpol, he is resistant to bribery and is often offended when someone attempts to bribe him.

Zenigata doesn't tend to drink or smoke as much as Jigen or Lupin, but often goes on binges when in a state of depression. In Memories of the Flame: Tokyo Crisis, he drinks heavily after being suspended from the force and has to be carried home by Maria.

Because he does not spend much time in one place, Zenigata never bothers to clean up after himself and is extremely messy. His apartment, hotel rooms, and desk at Interpol are usually cluttered with cigarettes, papers and empty bottles.

Zenigata is not dependent on his police badge. In The Mystery of Mamo, after having been ordered to stop chasing after Lupin, he resigns and declares that he will chase Lupin as a citizen. While in Tokyo Crisis, he continues to investagate even after having been suspended.
