Oliver Hansen is a very powerful mutant, who unfortunately, cannot control his sonic powers. Every time Oliver speaks, a burst of intense sound and kinetic energy is released leaving only destruction before Oliver. Because of this, Oliver became mute, never speaking for fear that he may hurt those he loved. He finally went to the institute where one of their techies made him a mask. It kept him from speaking and it could read his mind to speak for him. Finally, after many years, Oliver could speak. Despite the new ability, Oliver is still a quiet kid, speaking only when he has to. His mask also allows Oliver to potentially focus his real voice so he may use it for good. He would use this feature of his mask when he becomes Voice, a hero whose voice could level cities or evil in its tracks.
