A few episodes of Darkwing Duck were banned. The most infamous was season 3's "Darkwing Duck: Hot Spells (1992)" which only aired once on ABC. The plot line involved Gosalyn trying to gain magic powers like Morgana, and, in the process, selling Darkwing's soul to the devil. Another banned episode was "Darkwing Duck: Aduckyphobia (1991)", which was believed to be banned because it parodied Spider-Man.
This show not only spoofs elements of the Batman films and comics and the Shadow, but the intelligence organization, SHUSH, also parodies Marvel Comics' SHIELD, a super spy organization that often requests the aid of superheroes, especially Captain America, on missions. Darkwing Duck's outfit was also influenced by the Scarlet Pimpernel.
In several episodes there are references to cartoonist Gary Larson, creator of the comic strip "The Far Side". On one episode, Dr. Reginald Bushroot is teased by two fellow scientists, a Dr. Gary and a Dr. Larson. In another cartoon, aliens identify themselves as being from "the far side of the planet Larson".
The first season and syndicated version were released at the same time. Because of this, the nefarious five archenemies appeared in the daily stripped shows before their origin stories appeared in the weekly show. It was several years before the first season was integrated into the syndication schedule.
Jim Cummings (Darkwing Duck/Drake Mallard) has said that out of all the roles he's voiced, Darkwing Duck is his favorite. The reason for this is because of the character's flexibility. There were loads of opportunities for ad-lib, thus making the portrayal of Darkwing a lot more fun.
The creators admitted that the show was created specifically as a satirical parody of Batman, in particular the 1989 film featuring Michael Keaton. Early versions of the series were going to have a Robin-like sidekick and a butler like Alfred, but in an effort to not call too much attention to Batman, these characters were dropped and Launchpad McQuack was added in place of these two roles.
An earlier version of the show was originally going to be called "Double-O-Ducks". This idea was scrapped, as it turned out that "Double-O" was a copyrighted name, created by Ian Fleming, and owned by Albert R. Broccoli, producer of the James Bond films.
