I remember seeing a few episodes after the 1987 movie that had the new characters from the movie. Also it showed the return of Cobra Commander as a man (not a snake) wearing the silver armor. I don't remember much else. Does anyone remember this? Any thoughts as to where I get get info about them? joeheadquarters.com doesn't list any episodes after the movie. Did I dream this or what?
The short answer is that another animation company, DIC, produced more cartoons: The 1989 "Operation: Dragonfire" miniseries in which CC returns to human form, and two seasons of cartoons that ran in 1990 and 1991. Most fans consider the DIC shows an insult to G. I. Joe.
