Jonathan Tobias Mouse, or simply Jonathan Mouse, was a male anthropomorphic mouse.
Born in 1754 in the City of Worcester, Jonathan Mouse took part in the American Independence War of 1776. Around that time, he was briefly transported to the year 1943 by his great-great-great-grandson Mickey Mouse's Electro-Box, and befriended his descendant. Returned to his time period, Jonathan eventually married. Unfortunately for the good-natured Jonathan, his son Tex became a notorious outlaw in the Southwest.
