Vox

Vox is a tall and slim-figured, technology-themed demon who stands at approximately 7 feet.[6] 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. While using his hypnosis powers, or when he gets mad, his left eye gains a black spiral and the pupil becomes a cyan electric symbol.

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. He also appears to have dark navy-blue skin with sharp, cyan claw-like fingers.

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 shirt with an upside-down broadcast symbol and a rather large, red bowtie. He also wears heeled dark gray dress shoes with cyan-colored laces, toes, and tips on the heels.

He also wears a 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 the hat, the right one bent into a zigzag.

Vox is an egotistical, charismatic, and manipulative showman of an Overlord who craves attention.[7] 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.[8] 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 Overlords and seeks to maintain their collective image of power. As the most level-headed member, Vox often acts as the de facto leader of the Vees. Claiming the Vees' brand to be "perfection", he is often frustrated or outright angered if someone can jeopardize it, such as when he reigns in his fellow Vee, Valentino, from attacking the Hazbin Hotel in response to Angel Dust living there. Another element that earns his ire is his rival, Alastor, whom he utterly despises and might be intimidated by as he sees Alastor as a threat to his plans. However, despite his immense hatred for Alastor, Vox doesn't let it override his more pragmatic side once he calms down.

In "The Show Must Go On", he takes pleasure and joy out of seeing people fight and trying to kill each other, which causes him to get verbally explicit and overly honest, as seen when he along with Valentino and Velvette watch the fight between Adam and Alastor at the Hotel, commenting how the impending duel was given him an erection. He even shows this sadistic joy when he sees Alastor lose to Adam, saying that seeing Alastor suffer is better than sex, only to get angry when Alastor flees from the fight.
