Vox is a Sinner demon and one of the many Overlords of Hell. Vox is the founder, owner, and CEO of VoxTek Enterprises, along with being the de facto leader and public face of the Overlord trio known as the Vees, alongside Valentino and Velvette. A technology-savvy businessman, Vox pulls the strings of Hell's news and entertainment media. He is determined to keep his iron grip over Pentagram City's citizens from the Radio Demon, Alastor, his arch-rival in terms of influence and technology.
Vox is a tall and slim-figured, 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 simply becomes enraged, his left eye opens up more than his left, gains a black spiral and the pupil becomes a shifting 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 shark-like gills on the sides of his body. 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 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. 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. 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, the Vees, and seeks to maintain their collective image of power. As the most level-headed member of the Vees, Vox 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, 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.
When Vox was alive in the 1950s, he was a leader of a movement, also known as a cult. He was the center of attention all the time, so many people under his control and power. He also had a wife however, who would take care of these people by cooking, cleaning, everything that they needed.
However, Vox would cheat a lot with the women of his cult, hooking up with them. But when his wife found out, she lost control and stabbed all the women in the chest and killed Vox by electrocuting him when he was in a bath, and she pushed a TV in it.
Now in Hell, he was an overlord. One day, he decided to visit the Hazbin Hotel, just to get under Alastor’s skin, but he wasn’t expecting to see an old flame.
He entered the Hotel, but immediately caught sight of a small cyclops demon, by the name of ‘Niffty’. He heard of her, and knew her soul was under control of Alastor, his enemy. However… nobody else seemed to be around.
