“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.
Enter Mind Control.

Universo — “The Legion of Super-Heroes” Part 2
After his defeat at the hands of the Legion, Universo was (apparently) imprisoned but he (also apparently escaped) and commenced one of his campaigns to control the Earth. Being the master plotter that he is, he waited for or manufactured reasons for the Legion to be away from the Earth before beginning his plan for world domination. When the Legionnaires returned, they found that they were not only disbanded, they were hunted and outlawed!
“Dial H for Hero!”
A mysterious telephone dial-like device that is capable of transforming whomever dials the letters H‑E-R‑O on in into a superhero, or, rather, a series of different superheroes. (Of course, its a little hard to so describe the H‑Dial now, as telephones don’t have dials, they have keypads.) Boy scientist Robby Reed first discovered the H‑dial in a cave in Colorado and used it to protect the town of Littleville. Several years later, teenagers Chris King and Vicki Grant would discover a different pair of dials marked similarly, which they used to become superheroes. Later, others, too, possessed one of the H‑Dials. Currently, the power of the H‑Dial is passing among ordinary people in the New 52 DC era.
As might be expected, a few of the heroes these people transformed into had hypnotic powers.
