Transformers Deluxe Movie Collection 2 - Generation Dirge
There is a certain sub-harmonic frequency that triggers the fear response in most living things across the galaxy. DIRGE has used this frequency for centuries, tuning his engines and his vocal processor to generate it. Fear accompanies him like a dark cloud, everywhere he goes. Even his fellow DECEPTICONS feel it. He enjoys the feeling of power he gets, watching other robots quaking in fear at his presence, or fleeing at the sound of his engines.
