Ernie Fellerbottom graduated university with a degree in engineering. Afterwards he poured all his efforts into creating animated cowboys for an amusement park. The park organizers couldn’t afford to install the proposed wild west scene after an unfortunate legal battle concerning a Ferris wheel malfunction. So Ernie had a band of cybernetic outlaws with no place to go.
He did what any over-educated evil genius would do. He used them to rob banks.
