Vox is a tall, slim demon with a TV head projecting red-eyed, cyan-pupiled monitors. His left eye displays a black spiral when using hypnosis or enraged. His screen mouth reveals cyan teeth and a pointed tongue, occasionally dripping "blood." His navy-blue skin contrasts with cyan claw-like fingers. Attired in a navy tuxedo with coattails, red-trimmed cyan lapels, and a red-and-black striped waistcoat along with black-cyan shoes. Vox wears a red bow on his suit. He hates Alastor.
