Anton Allegro was a failed musician, who became deaf after an accident caused by Green Arrow. Later on, Allegro found an ancient mystical book, which granted his synthesizer magical properties and drove him mad. Using his magical synthesizer for evil, Allegro started attacking those who wronged him in his career, starting with Oliver Queen. This got the attention of the Justice League, who confronted Allegro and after an initial defeat, they were able to stop him for good with help from Zatanna. Afterwards, Allegro was sent to Arkham Asylum.
