Vox is a tall, technology-themed sinner demon with a humanoid body who stands at approximately 7 feet tall.[15] 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[16] 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.Vox is an egotistical, charismatic, and manipulative showman of an Overlord who craves attention.[17] To the public, Vox presents himself as a legitimate businessman of VoxTek Enterprises, giving the facade of a man of the people to the denizens of Hell, when in truth, he is power-hungry, and he manipulates their minds to boost his reputation. He is highly intelligent and technology-savvy, and he is always keeping up with the latest trends and technology.[18] He seems to be able to hide his less desirable side in public and even in private unless he's pushed too far. Despite his egocentric nature, Vox is loyal to the interests of his fellow Vees and seeks to maintain their collective image of power, and as the most level-headed member of the Vees (except where Alastor is concerned), he often acts as the de facto leader. Claiming the Vees' brand to be "perfection", he is often frustrated or outright angered if someone can jeopardize it. Another element that earns his ire is his rival, Alastor, whom he utterly despises and sees Alastor he sees him as a threat to his plans. However, despite his immense hatred for Alastor, Vox is obsessed with him. he is affectionate towards his pet shark, Shok.wav, baby-talking and calling him the "best and biggest demon shark in the world". Years back when alastor and him were friends, Vox was more mild-mannered in regards to Alastor, viewing him as an inspiration and a friend. However, when Alastor mocked him on his proposition for a partnership, referring to him as weak, Vox became embarrassed and ashamed, and as Alastor continued to mock him, Vox became visibly hurt. Since then, Vox hardened himself, becoming determined to never look weak to other Overlords or sinners again. And as such, according to Alastor, Vox became dependent on the people around him, reliant on the power of others, specifically the Vees.
