Vox is a slim, technology-themed demon, standing at approximately 7 feet with a flat-screen TV for a head. The monitor projects two eyes with red sclera and light blue pupils, the outline and wrinkles of his left eye being cyan, and a mouth with sharp teeth that glows light blue.

His skin is dark grey and his fingers are light blue from the second knuckle.

He wears a dark blue tuxedo with lighter stripes and a black and red striped shirt. He has a red bow tie and a light blue undershirt.
