When Dr. Ivo Robotnik conquered the city of Mobotropolis, Sherman was part of the initial resistance group which attempted to retake the city. Sadly, Sherman was among those killed in the battle, while the rest of the resistance either escaped or were roboticized. However, his wife managed to escape while pregnant with their second son, and Rotor would carry on his father's legacy as a member of the Knothole Freedom Fighters. (CSE)
