Donna Duck is a female anthropomorphic duck.
A seductive Mexican élégante, Donna Duck had a fling with Donald Duck in 1937 before Donald more lastingly fixed himself up with Donna's near-lookalike Daisy Duck. On top of no small amounts of pride, Donna shares Donald's irritability. Since dating Donald, Donna, who has since moved to Duckburg, had a string of boyfriends, including one Manuel Gonzales and Donald's own cousin Whitewater.
Donna first appeared in the 1937 cartoon Don Donald.
Relationship with Daisy Duck
She was a precursor to Daisy Duck, with the out-of-universe consensus being that Donna is little more than Daisy under another name and in Mexican garb (a fact even acknowledged in the reference book The Duckburg Dictionary). In-universe, however, they were established as different people as early as the 1950's, when she appeared alongside Daisy in the Al Taliaferro-drawn Donald Duck comic strips, with all the humorous possibilities of Daisy coming face to face with an ex of Donald's. Carl Barks (who contributed to Daisy's creation, having written for her debut film Mr Duck Steps Out) went on record to note he did not think of Donna and Daisy as a single character at the time.
Nevertheless, the 1995 story Donald Duck and the Secret of the 313 (written by Fabio Michelini) instead depicted Don Donald as an in-universe film in which Donald starred as himself, and Daisy as the apparently fictional "Donna". The best way to reconcile this puzzling fact with established continuity is to assume the shooting seen in the 1995 tale was of a film based on the events of Don Donald, which remains, in and on themselves, canonical in its own right.
Due to her stark resemblance to her successor Daisy, it has sometimes been speculated that Donna is none other than Daisy's Sister, the ever-offscreen mother of April, May and June. This opinion has been echoed by Don Rosa. Such an interpretation butchers previous continuity, however, as Daisy and Donna are shown not to know one another during their meeting in the 1950's Taliaferro strips.
Curiously, INDUCKS has two different codes for the character, one for the original Donna of the 1930's, and another for the version of the character used in the 1950's in the comic-strips. This may be due to the slightly modernized appearance of Taliaferro's Donna, who notably gained a shirt, where her only items of clothing in the original cartoon were her headdress and a shawl.
