Duckworth is an anthropomorphic dog.
Description
Duckworth is Scrooge McDuck's distinguished and practical butler and chauffeur at McDuck Mansion (as opposed to Quackmore, who rather works at the Money Bin). He often took part in Scrooge's adventure while he was living in McDuck Mansion with his grandnephews. Duckworth, in spite of his ridiculously small salary and the mistreatments he suffers from Scrooge, has been shown to love his job as a butler, and was deeply depressed when Scrooge, thinking Duckworth was dissatisfied with his job, fired him (allegedly "for his own good").
Behind the scenes
Duckworth was created in 1987 for The Treasure of the Golden Suns.
His first name is unknown. However, he is usually called by his first name in some of DuckTales' foreign translations; excluding the first names that do not exist in English, this leaves the options of Archibald ("Archie" is his Italian name), Leopold (Portuguese) or Albert (Danish).
