“Masters of the Universe: Teela’s Secret”
There was a change in cartoons in the 1970’s, following a misplaced furor about violence in children’s cartoons. Violence, even cartoon violence, was suddenly forbidden. That was the reason you never saw Thundarr the Barbarian decapitate anyone with his Sun Sword. It was why Cobra pilots always bailed out before their jets exploded. It was why GI Joe and Cobra used laser weapons that only seemed to affect tanks and jeeps instead of ordinary rifles and machine guns. (The latter was also cheaper to animate.)
It forced writers to develop new and different (or old and different) stories and plot devices on a weekly basis.
