Watcher

Watcher was the international police officer (who quickly jumped to conclusions), in charge of the investigation of Al Fish' murder.

Al Fish' murder
The first week Watcher was in America, Al Fish was murdered in Roxanne Roadman's office. After hearing an (According to Watcher) odd scream, he kicked in the door, and arrested the first person in sight on the crime scene."In this case, Watcher came of as kind of lazy. However, he was just tired from traveling all the way from Shanghai to Redroad City."Watcher gave Ikenberry a chance to prove his innosence, by having him solve the case. After examining the victim's body, Watcher ordered Ikenberry to bring the blood on the floor to the forensic inspector Crimley McSang.

After the true culprit was arrested, Watcher gave Ikenberry his favorite coffeecup as a token of appreciation.

Detective Kamen; Nocturnal Investigations
In DK; NI (which takes place in 2020), Watcher is 66. Despite this, he looks just as young as in Percy Ikenberry 1. His hair has bleached a little, though.

Nationality
In all versions (except for the French version, where he's British) Watcher comes from France.

Trivia

Name

 * Watcher was named after Looker from Pokémon. Another international police officer. Where Looker comes from a word for someone who looks good, Watcher, quite literally comes from the verb "Watching."
 * The French Spectateur means "Spectator"
 * His Japanese codename comes from the fact that some people can't see thing when they don't wear glasses (or spectacles). Sticking with the watching theme.
 * Herr Zuschauer, Detrick Daht's nickname for him, literally means "Mr Spectator" in German, a nod to his French name of the same meaning. Zuschauer is canonically Watcher 's German name.
