Vox is a tall, technology-themed sinner demon with a humanoid body who stands at approximately 7 feet tall. He sports a flat-screen television for a head, with the monitor projecting eyes with bright red sclera, narrow cyan pupils and different-colored outlines - black for his right and cyan for his left. While he is using his hypnosis powers or feels strong emotion, his left eye opens more than his right eye, contains endlessly growing black concentric circles, and the pupil becomes a shivering cyan-colored electric bolt. The screen also shows a mouth full of jagged, cyan-colored teeth and a long pointed cyan colored tongue. Sometimes two red columns resembling blood seem to drip out of his mouth, particularly when he's excited. He has dark navy-blue skin with sharp, cyan claw-like fingers, and also has what appears to be three cyan shark-like gills on the sides of his body and cyan rectangular nipples. Vox wears a navy-blue tuxedo with the jacket sporting coattails, red-trimmed cyan lapels, thin cyan stripes and cyan lining, worn over a red-and-black-striped waistcoat which itself is worn over a collared bluish-white dress shirt with an upside-down broadcast symbol and a rather large, red bowtie. He also wears dark navy blue slacks, heeled dark gray dress shoes with cyan-colored laces, toes, and tips on the heels. He also wears a small black top hat on his head, with red and blue designs reminiscent of a broadcast symbol and radio wave symbol, respectively. He has TV antenna that stick out the top of his hat, the left one bent into a zigzag. He is obsessed with sharks
