Novel & Cerita Metal Sonic Sonic X

"Those aren't men. Those are monsters..." The lead entity paused at the base of the cliff. It tilted its head back, its jaw unhinging with a wet, sickening crack as it let out a sound that wasn't a roar—it was a high-pitched, vibrating shriek that bypassed the ears and vibrated directly inside the human mercenaries' skulls. Three of the elite guards instantly dropped to their knees, blood erupting from their ears and noses as their brains violently misfired under the sonic assault.
