Bito Wladon is a resident of the small Balkan nation of Modora who is ostracized due to his parents being deaf. In response, he develops the "nucleo-sonic motor", which can manipulate sound, and becomes a supervillain and enemy of Green Lantern.
Sonar is later defeated and stripped of his technology. However, he is proud of his newfound notoriety. The people of Modora show their gratitude to Green Lantern by creating a Modoran postage stamp for the hero, which he gives to Thomas Kalmaku to complete his stamp collection.
Sonar later escapes prison by exploiting a legal loophole, murders Modora's royal family, and replaces them as ruler.
In "Doomsday Clock", Sonar is among the villains who meet with the Riddler to discuss the Superman Theory.[2]

Third Sonar
The third Sonar is Bito Wladon's son, Bito Wladon Jr. He possesses cybnetic enhancements that give him the innate ability to manipulate sound.[4]
Powers and abilities
Wladon carries a Sonic Sceptre, a device that enables him to absorb sound, which he can also use to fly, project illusions, fire sonic attacks, and telekinetically manipulate objects.
Wladon Jr. is cybernetically enhanced to harness ambient sound and use for his own purposes. He usually attacks by firing sonic blasts.
