A few episodes of this show were banned. The most infamous was season three, episode eight, "Hot Spells", which only aired once on ABC. The plotline involved Gosalyn trying to gain magic powers like Morgana, and, in the process, selling Darkwing's soul to the devil. Another banned episode was season one, episode twenty-three, "Aduckyphobia", which was believed to be banned because it parodied Spider-Man.
DuckTales: Os Caçadores de Aventuras (1987) and this show had a spin-off show that never happened called "Justice Ducks". The show would have featured Darkwing Duck and Gizmo Duck teaming up with some new heroes.
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.
Launchpad McQuack is the first Disney television cartoon character to appear in two separate cartoon shows (he first appeared in DuckTales: Os Caçadores de Aventuras (1987)).
This show not only spoofed elements of the Batman movies and comics, and the Shadow, but the intelligence organization, S.H.U.S.H., also parodied Marvel Comics' S.H.I.E.L.D., 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.
