A character from the Strider science fiction Video Game from 1989.
The Hit Mouse (ヒットマウス) is a minor stage Robot enemy from the first Strider and most of its ports.
The Hit Mouse is a fast and agile small semi-spherical flying cannon drone which rotates and moves in a wavy line pattern while attacking. They are usually deployed in large groups of around 5 to 6 units, floating into view from either the top or bottom of the area, and move in waves as they constantly shoot at their acquired target.
