Flash Gordon
In 1980, Mattel released the first wave of figures based on the Filmation Animated series "Flash Gordon", ( You can read my review of the DVD here) The line was very accurate to the source material, despite the figure bodies being short. It's body style was used earlier on the Battle Star Galactica line and like that line, the second wave of figures (Vultan, Captain Arak etc) is much tougher to find. 
The Space ships in this line were inflatable, which is kind of strange. It must have been an attempt to make a lower cost larger vehicle for the series.
