Partner to Shock-headed Peter, Duane is long suffering of Peter's bigotry. A reluctant bachelor who is often shown to be afraid of his mother (a superhuman lie detector). Duane is seen flirting with Jack Phantom even though he is aware she is a lesbian and outranks him. He takes it very hard and blames himself when Professor Gromolko slips free when in custody and uses one of his 12-shooters to commit suicide. Five years after the Ultima incident, Dust Devil's mother has died, and he finds solace in the arms of his new partner, Curlew.
