He is the descendent of Shropshire Slasher from the Looney Tunes short "Deduce, You Say". Stomper's Mom is the head of a robotics company and built Stomper's arms and legs. Duck unwittingly took down Stomper when Tech's new invention brought him down. Stomper vowed revenge and switched places with his mother (whom was in a robot suit resembling Stomper). When Duck admitted Tech stopped the Stomper, Stomper began to target both of them and found them hiding in the sewers. He was defeated and now joins his mother in jail.
