DuckTales
The cartoon premiered worldwide between 18–20 September 1987 (the time and date varying between markets), with a television movie special entitled ""The Treasure of the Golden Suns"", which was later split up into a five-part serial in future reruns. The first season, aired between 1987–88, consisted of 65 episodes, the "magic number" requirement needed for a show to have a weekday syndication (five days a week for thirteen weeks). Disney then commissioned three more seasons – the second season (aired between 1988–89) consisted of two television specials entitled "Time Is Money" and "Super DuckTales", with future reruns splitting them into two five-part serials; the third season (aired between 1989–90) consisted of 18 episodes, with it forming an hour-long syndicated block alongside ""; and the fourth season (aired during late 1990) consisted of seven episodes (including three unaired episode meant for the previous season), which was used to form a two-hour long syndicated block called "The Disney Afternoon", consisting of "DuckTales" and three other half-hour cartoons.
Darkwing Duck
Though originally believed by some fans to be a spin-off of the 1987 "DuckTales" series, creator Tad Stones stated in a 2016 report that he believes the two shows exist in different universes, despite "DuckTales" supporting character Launchpad McQuack appearing on the series in a similar role to that the character plays in "DuckTales", and the fact that Scrooge McDuck, the main character of "DuckTales", is mentioned in "Darkwing Duck" episode "Tiff of the Titans". Additionally, the 2011 comic series "DuckTales" makes reference to Darkwing Duck and features various villains from the series. A crossover between the "Darkwing Duck" comic series and the "DuckTales" comic series occurs respectively in the seventeenth and eighteenth issues and the fifth and sixth issues of the series.
