Darkwing Duck was part of the Disney Afternoon, a great block of syndicated cartoons that ran for most of the 1990s. Pretty much every show on the Disney Afternoon was awesome: DuckTales, Gargoyles, Chip ‘n Dale Rescue Rangers, TaleSpin, and so on.
Darkwing Duck was a semi-spinoff of DuckTales–Darkwing himself never appeared on the show, but the premise was inspired by the DuckTales episodes “Double-O-Duck” and “The Masked Mallard.” But enough regurgitating information you can find on Wikipedia–the important thing here is Playmates produced a line of toys based on Darkwing Duck. I owned a Darkwing figure myself, now sadly lost.
The merchandising for the various Disney Afternoon shows was spotty at best (the only show I can remember getting a full, decent toy line is Gargoyles), so it’s not surprising that the Darkwing Duck line only made it to one wave. However, as you can see above, we have some pics of what the second series would have looked like, and it would have been painfully awesome. I would have given my right eye in a Faustian bargain for that Gizmoduck alone.
