Dial "Q" for Quick: Spelling + Math Equals Adventure!
Robby Reed came upon an alien dial which, when he learned to transcribe it, allowed him to "Dial 'H' for Hero", or so the saying goes. Similarly, Johnny Chambers acquired from his guardian Professor Gill the means to access a formula making him a costumed crusader. While Robby's counterpart on Earth-Two, Scribbly Jibbet, was more a hero magnet given his dual career as a cartoonist and journalist, wherein he tied into the comic book creators from Earth-Prime, Johnny's doppleganger on Earth-Two was the fellow speedster Kid Flash aka Wally West.
On one occasion early in his career, Robby was transformed into the Earth-One version of Plastic Man, a form he'd adopt later. Scribbly had various adventures alongside the golden age Red Tornado, and later Law's Legionnaires. One of the allies of Earth-Two's Plastic Man was Johnny Quick, who like Reed gained temporary powers. Various alphabetic and alphanumeric combinations allowed these men to become something more. Among these were the following, which were but the tip of unleashing awesome abilities:
H.E.R.O. and 3X2(9YZ)4A unleashed superhuman power for good.
O.R.E.H. and Z25Y(2AB)6 returned an individual to normal again,
V.I.L.L.I.A.N. and 3X2(9YZ)4AX turned one into an evil superhuman.
H.O.R.R.O.R. and 4G-7E(3X3W)6X gave one a monstrous physique.
H.E.R.O.I.N.E. and ZYM04N13/1 always granted temporary powers.
Several more undocumented combinations yielded similar effects.
After a series of adventures, Reed gained amnesia wherein he became evil, only to regain his senses while battling his Earth-Two counterpart, Plastic Man, who had migrated to Earth-One shortly before this encounter. Some time after this, in order to save Earth-One from destruction Robby had to dial S.P.L.I.T. in order to become two individuals, the Wizard who flew off to defeat the villain behind the death trap, and the Master who ingeniously deactivated the global bomb. It was then realized by both individuals that the Wizard possessed all of Reed's inherent good, and the Master all his inherent evil. While the Wizard developed two more power dials like that which powered Robby, the Master slayed his good-nature clone. But the seeds were then planted.
The counterparts for Victoria "Vicki" Grant and Christopher "Chris" King who became his heirs to the hero dials were Elizabeth "Libby" Lawrence and Richard "Rickey" Cannon. Libby was the heroine known as Liberty Belle, and she gained her power from a miniaturized liberty bell the channeled sonic vibrations into her power giving her superpowers for periods of time, much like Vicki and Chris received from their necklace and watch, respectively. Rickey was a master of disguise as a government agent who aided Belle in various adventures, although it was Libby's husband Johnny Chambers aka Johnny Quick who like Chris King utilized formulas to tan temporary superpowers. Both Vicki and Chris and Libby and Rickey had government agent fathers in Detective Greg King and Major James Chambers.
In another strip of Johnny Quick, series creator Mort Meskin Jr. manifested himself upon that reality, and was instrumental at orchestrating events in that world. Hence, he like Mayer were the implements by which mystery men were spawned on this and other worlds throughout the Multiverse.
