Duckworth is Scrooge McDuck's longtime, no-nonsense butler and chauffeur in DuckTales.
Despite having "Duck" in his name, Duckworth is actually an anthropomorphic dog. He worked for Scrooge even before the nephews moved in. He's Scrooge's chauffeur and errand boy on occasion. Duckworth used to be Scrooge's only household servant until Scrooge hired Mrs. Beakley. He also is the servant of the house.
He usually appears as a supporting character. His only starring roles on the show were in the episodes "Duckworth's Revolt" and "Take Me Out of the Ballgame". In these two episodes he shows he's a capable leader and his out of the box thinking comes in handy, whether its helping Doofus hit a baseball or steering an out of control flying saucer.
Duckworth is a jack-of-all-trades in the McDuck mansion, making him an important member of Scrooge's staff. He is happiest when he's helping someone and has no real interest of going out in the world to seek his own fortune.
In the Dutch version of the 1987 TV special, Sport Goofy in Soccermania, Scrooge's butler (who was called "Jeeves" in the original version) was dubbed "Van Stoetenwolf", Duckworth's official Dutch name.
Duckworth role can be compared easily to Alfred Pennyworth's in the Batman comics.
Duckworth has apparently been included in the 2017 ‘’DuckTales’’ series but has not been officially introduced; he will appear in the episode "McMystery at McDuck McManor!"
