Stunning Sounds Synthesize Superheroes

Among the scores of adolscent superheroes, from those relying only on their carefully trained physical skills to those embued with powers caused from genetics to accidental mutations, a few derived their abilities from sonic vibrations. Two pairs of Dynamic Duos on parallel planets when gained amazing attributes from soundwaves were Hawk and Dove of Earth-One, and Toughy and Tubby of Earth-Two. 

Hank and Don Hall were brothers with conflicting world views. Hank sought to fight back when he saw oppression, which led to his violent demeanor. Don sought to find common ground with his opponents, which led to his peaceful attitude. There father, Judge Irwin Hall, displayed balanced between these two opposing philosophies, displaying justice when necessary and mercy when possible. 

Herbert "Toughy" Simms and Richard "Tubby" Mehlville weren't blood relatives, but best friends. These young lads were emotionally balanced, and much as teenagers can be, although physically they were drastically different. Herbert was physically fit and strong, whereas Richard was overweight and durable. They were mentored by their friend Tommy's father, District Attorney Dan Rogers, who taught the three lads the true meaning of justice.

When a local mobster in the city of Elmond threatened Judge Hall’s life, Hank and Don tracked down his gang to a building where they met, yet found themselves trapped in a room within the criminals’ hideout. The Hall boys then heard an incorporeal voice offer them power only when justice needs to be served. By calling out their heroic alter ego names, Hawk for Hank and Dove for Don, the teens transform into costumed crusaders, with Hawk’s athletic abilities amplified to near superhuman strength, while Don’s gymnastic aptitude gives him remarkable agility. Together, they would be joined in their adventures by the horn playing hero Mal “Guardian” Duncan and the red-haired Lilith, and would join the Teen Titans. It’s unknown if perhaps the same incorporeal voice is connected to Mal’s special horn, which could teleport Duncan and others to various locations where needed. These four joined the first members of the Teen Titans: Robin, Speedy, Kid Flash, Aqualad, Wonder Girl, and the Titans’ later members.

When a gang boss began terrorizing Big City, District Attorney Rogers was powerless to stop them. This motivated Tommy into adopting a heroic horn playing alter ego of Little Boy Blue, and inspired Toughy and Tubby into joined him as costumed crusaders. Together, they were able to bring the gang and its leader to justice, and had several adventures throughout the years as the Blue Boys, with the harmonious melody of Tommy’s horn seemingly calling his friends to action no matter where they are in relation to him. It’s unknown if Little Boy Blue’s special horn could imbue the three lads with abilities far beyond those of males their age, as the Blue Boys displayed above average strength and agility. Eventually, they were made members of the All-Star Squadron, where they were teammates with fellow Robin, Speedy, Johnny Quick, Neptune Perkins, Wonder Woman and others.
