Marvin the Martian only makes a few appearances in the show, with only one prominent role. Marvin appears with his protege, Marcia, in "The Return to the Acme Acres Zone" episode segment "Duck Dodgers Jr.", also starring Plucky Duck and Daffy Duck. In the short, Daffy reprises his role as Duck Dodgers of the 241/2 Century, with Plucky serving as his trusty sidekick. Their mission is to stop a matter transmogrifier from sucking up the entire universe, which Marvin and Marcia are behind. While Daffy and Marvin fight over the universe, Plucky and Marcia go off to play together.
