Police Inspector Tawashi (often shortened to Inspector Tawashi, his first name was never mentioned) is a detective and also head of the Metro City Police.

In the beginning, he is shown to dislike robots, especially ones with Kokoro (the reason isn't made clear). That distrust carried on for most of the series, until finally in the Robotonia battle he, although didn't take sides with the robots (like Dr O'Shay and Dr Tenma) he finally shown some compassion towards them.

Tawashi's most notable feature is his nose, which is shaped a shoebrush and hangs in a fashion similar to O'Shays.
