Siren's voice modulator goes to eleven—and stays there. Thanks to his ear-splitting upbringing in the Sonic Canyons, he operates at full volume all the time. While this may annoy his pals Nightbeat and Hosehead, it drives his partner Quig nuts. Eventually, Quig's efforts to teach Siren about the concept of an "indoor voice" may succeed, but for now Siren doesn't really listen to him, either because he can't hear him or because he doesn't want to.
