Inspector Gumshoe is a police detective. His most distinguishing feature is his mustache that looks like a shoe brush on his long nose, hence his name. Usually, he's has a rivalry with Astro, often accusing him of unsolved crimes. Their relationship began to grow in the series.
In this series, Inspector Gumshoe is named Detective Tawashi. His antagonism toward robots is softened a little, as he trusts Astro and Delta during crime sprees. He's very loyal in protecting the city at all costs.
