Silver Age team
The Dial H for hero team era started when Robbi Reed dialed D-I-V-I-D-E, splitting himself in two different identities: the good Wizard and the evil Master. To stop his evil side, who was building an army of supervillians the Wizard built new H-dials for teenagers Vicky Grant and Chris King.. These dials--disguised as a watch and a necklace--only have the letters H-E-R-O on them, and work only for an hour, after which they will not work for another hour. King and Grant begin protecting Fairfax from a number of menaces.
Robbie Reed would return in the series H.E.R.O. recruiting previous users of other Dial H who had retain uncounsciously superpowers. Together they had to stop a serial killer who had founded the Dial and had gained Superman level superpowers. Another team used the dial to make Jackass-like stunts.
