from the comics of Don Rosa and Carl Barks were used, alongside elements of others Disney stories (including the original 1987 DuckTales TV series, Darkwing Duck, TaleSpin, Chip 'n Dale Rescue Rangers, Quack Pack, Goof Troop and others). They were brought together into one common global storyline in the manner of the Marvel Cinematic Universe. Characters Donald Duck and his maternal uncle Scrooge McDuck received nearly equal exposure in comics. (The reduced emphasis on Donald in the 1980s version of DuckTales was largely due to a Disney mandate that forbade its nascent television division from using major characters from the Golden Age of Animation, including Donald and Daisy.) Other primary characters include Donald's three young nephews Huey, Dewey, and Louie, and girlfriend Daisy Duck. Several secondary characters have also achieved star status in certain publications, such as Grandma Duck, Donald Duck's grandmother; Gladstone Gander, Donald Duck's incredibly lucky cousin; Gyro Gearloose, an inventor who is often patronized by Scrooge; and Ludwig Von Drake, a knowledgeable professor. Scrooge also has several enemies, such as the Beagle Boys, a gang of robbers and escaped prisoners; Magica De Spell, an Italian sorceress; and South African Flintheart Glomgold and English-American John D. Rockerduck, both rival business men of Scrooge. Some characters have appeared alongside Donald primarily in animation, such as chipmunks Chip 'n' Dale (Chip an' Dale, Toy Tinkers) and Humphrey the Bear (Rugged Bear, Grin and Bear It), as well as Mickey Mouse (The Dognapper, Magician Mickey), Goofy (Polar Trappers, Frank Duck Brings 'Em Back Alive), and Pluto (Donald and Pluto, Window Cleaners), who are more often associated with the Mickey Mouse universe. Fictional locations Duckburg Duckburg is the fictional city, located in the fictional U.S. state of Calisota, that serves as the home of Donald Duck; Scrooge McDuck; Huey, Dewey, and Louie; Daisy Duck and most of their supporting cast. Duckburg was first mentioned in Walt Disney's Comics and Stories #49 in 1944, and was created by Carl Barks. The city is populated by various anthropomorphized animals, with dogs, different birds (including ducks, geese and chickens) and pigs as the most dominant ones. The mayor of the city is often depicted as a pig, whose name most of the time goes unmentioned and is referred instead by readers as the Pig Mayor. However, in some stories the office of mayor is held by various dog characters. The size and structure of Duckburg
