Vox is a slim, technology-themed demon standing at about 6 feet. He wears a striped tuxedo and a black and red striped shirt. He has a red bow tie and a light blue undershirt. He wears a black top hat with red and blue designs reminiscent of a broadcast symbol and radio wave symbol, respectively, and his antennas stick out of it.
He has a flat-screen TV for a head, and his eyes are red with light-blue pupils, but his left eye has black stripes and a jagged pupil. He has light blue teeth and what appears to be blood dripping from one side of his mouth. His eyebrows are different colors, the left's white and the right's dark blue.
Vox is stated to be quite the showman, and a charismatic, egotistical, and manipulative individual who craves attention.
- Electrical Manipulation: Depending on his emotions, Vox possesses the ability to control electricity. For instance, he can travel through television monitors and control them as he pleases. Vox can also turn into electricity. If he's angered, he can potentially make it so that a Hell-wide blackout happens.[note 4]
- The word "vox" is the shortened version of the word "vocals". It may also be the shortened version of the Latin word vox, meaning "voice".
- Vivienne and Hazbin writer Dave Capdevielle confirmed that Vox is one of the bigger antagonists in the series.
- According to Viv, he and Alastor don't get along due to their opposing views on technology, with Alastor disliking anything invented after his death in the 1930s and Vox embracing new technologies.
- Faustisse mentioned that Vivienne used music artists such as Skrillex and Knife Party songs, especially the song "Narcissistic Cannibal" to help herself create Vox's design.[note 5]
- Vivziepop's headcanon voice actor for Vox would be Mark Hamill.
- When asked what TV shows Vox would like, Viv stated Vox doesn't have a specific favorite when it comes to his preferences for TV shows, but it is noted that he likes to watch commercials and enjoys watching game shows.
- In the real-life fictional Voxtagram stories, Vox is the manager of the service.
- In these posts, Vox is depicted in a romantic on-off again relationship with fellow Overlord Valentino. From a live stream in Voxtagram that Blitzo and Stolas were drawing pictures, the username by the name of "Radvelvetcakes" (monitored by Velvet herself) mentioned that Vox and Valentino recently broke up. The comments made by Velvet and Stolas made on one of Velvet and Stolas's comments on Valentino's Instagram post further supports the idea that the two are romantically involved. Further messages also from the live stream imply it as a romantic one, although this is yet to be confirmed.
- In the Voxtagram stories, Vox owns a pet hammerhead shark named Vark.
- It's revealed in the Alastor Comic that Vox is the owner of a large company that sells products that start with V. It's also shown that he is the only person who can make Alastor swear, as when he hijacks the TV signal to make his face intimidate the latter, Alastor, while shrugging it off, goes on a quiet swearing tirade about Vox, showcasing his hatred for the former.
- According Vivziepop, Vox has eaten McDonald's before, therefore making himself think he is much better and superior to Alastor, who died before the chain was founded.
- According to Faustisse, Vox can play videos on his screen (his face).[note 6]
