Vox is a tall and slim-figured, technology-themed demon who stands at approximately 7 feet. He sports a flat-screen television for a head, with the monitor projecting eyes with red sclera, small cyan pupils and different-colored outlines - black for his right and cyan for his left. The screen also shows a mouth full of sharp, cyan-colored teeth and a long pointed tongue similar to Valentino's but cyan. Sometimes what looks like blood seems to drip out of his mouth.
