“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.
