Vox/Relationships

The Vees
According to Faustisse, he, Vox, and Velvette are very close friends who make up the Overload subgroup known as the Vees.

In the series, Vox has shown to be the de facto leader of the Vees as he is the most rational of them. However, Valentino and Velvette do seem to agree with Alastor that Vox would be powerless without them as they were smirking at the comment. The two know how much Vox hates Alastor and are somewhat weirded out by how overly excited and verbally explicit Vox gets when he sees Alastor in pain.

Velvette
Vox and Velvette seem to get along since they were hiding from the Exorcists in Valentino's studio. She even takes a selfie with him to his reluctance. The reason why Vox and Velvette get along quite well is that they are both up-to-date with the latest trends and technology.

Velvette seems to always have to call him to keep Valentino under control when he's angered. In "Radio Killed the Video Star", she has to call him from his floor to calm down Valentino when he was destroying everything and everyone in sight. She actually agreed with Vox's sworn nemesis, Alastor, that Vox would be nothing without her and Val.

In "The Show Must Go On", throughout the episode Velvette is disgusted by Vox's out of control, overly explicit and honest behavior. As soon as Alastor picks a fight with Adam, Vox becomes aroused and shouts how "hard" he was, much to her annoyance.

Valentino
The two are on relatively good terms, as Vox can be seen hiding out in Valentino's porn studio during the Extermination. Furthermore, Valentino's silhouette is on a product labelled "V&V's" that Vox advertises in the Alastor comic.

Vox seems to be the more dominant of the two as he would have to act as Valentino's babysitter when necessary. In "Radio Killed the Video Star", it has shown that Vox is the only person who can be around Valentino without suffering from when the latter is in one of his rampages. When this happens, Vox is summoned to act as his voice of reason in order to prevent him from damaging the Vees' reputation or prevent further casualties with his rage induced impulsivity. If this didn't work, Vox would have to yell at him before talking him down. Valentino, despite his controlling and vicious behavior, does know that it was serious when Vox snaps at him.

Vox is stated to being depicted in a romantic on-off again relationship with Valentino. In "Radio Killed the Video Star", Velvette has mention that Valentino is Vox's "little boy-toy", possibly hinting they are in relationship or at least hooking up. This is further hinted in "The Show Must Go On", as the two were singing and dancing in a amorous way and share a passionate tongue kiss, implying they are in a romantic relationship instead of one of Valentino's usual strictly sexual relationships with others. It's currently unknown if Vox is even aware of Valentino's sexual flings with his employees.

In the Voxtagram posts, this relationship appeared, at times, to be physically and verbally abusive, whether this relationship is reflective of their canon dynamic at all is currently unknown, as the actual events of the Instagram story arcs themselves are not.

In "The Show Must Go On", Valentino gives Vox a disapproved look when he said Alastor almost dying is better than sex and becomes amused when Vox threw a fit when he retreated from Adam.

Alastor
According to Vivziepop, the two don't get along due to their different views and preferences when it comes to technology. Vox has been stated to have a one-sided obsession with Alastor, wanting the sinner to notice him.

In The Radio Demon comic, Alastor briefly sees Vox's advertisements while passing by a store. When confronted by Vox, Alastor states he is a "show off" who's "all hat and no cattle!"; upon getting some distance away, Alastor quietly grumbles and swears, calling Vox obnoxious, pompous, egotistical, and annoying.

Their rivalry and distain for one another is made clear in "Radio Killed the Video Star". Seven years prior to series, Alastor and Vox engaged in a confrontation where Alastor nearly beat him. Furthermore, their duet, "Stayed Gone", emphasizes their respective stances on technology and even their past with Alastor mentioning how Vox asked him to join his team but declined.

It can also be implied that the two have been friends or at least associates at some point before their rivalry as seen in "The Show Must Go On" when a ripped picture of Alastor (without the usual "filter" he provides) and Vox is seen.

Carmilla Carmine
Vox appears to be acquainted with Carmilla, though he refers her derisively when talking to his assistant after making up VoxTek Angelic Security, presumably it can be indicated that he only maintains his association with the other Overlord due to his business interest. In "Scrambled Eggs" his disrespect for her is further shown when he declines to attend the meeting of Overlords hosted by Carmilla, and instead delegating Velvette to represent the Vees. Over a conversation on the phone between him and Velvette, it's clear he regards Carmilla and the other Overlords as a joke while Carmilla sees him and his group as disrespectful and out of control.

Lucifer Morningstar
Vox appears to be at least known Lucifer's name by reputation. In "The Show Must Go On" Vox expresses dumbfounded shock at hearing Lucifer say he will "fuck you" to Adam. After the end of the battle, in the Finale, it's revealed that Vox and his fellow Vees made a mindmap containing images of their enemies, which includes Lucifer.

Charlie Morningstar
Though Charlie is the princess of Hell, her name carries little weight, so much so that even Vox initially was indifferent to her status. Even when one of his fellow Vees's associates was currently residing with her, the Overlord did not find this at all to be upsetting. Vox only begun to view Charlie as a person of interest only when he learned that his old rival, Alastor, was currently working with her on the Hazbin Hotel. This caused him to focus his attention on the princess with zeal, even setting her and her staff on surveillance.

Vox appears to be determined to ensure that Charlie makes no deal with Alastor. He refers to her as "Lucifer's brat", presumably due to her association with Alastor or his disrespect towards her, though he appears to be familiar with her compassionate personality, which he sought to exploit. After the early Extermination was canceled, it was revealed that Vox and his fellow Vees have a mindmap that includes Charlie as one of their enemies.

Angel Dust
Angel Dust is one of Valentino's employees. Although it's unclear how Vox feels about him, in Masquerade, while shaking Valentino's hand, Vox takes a side glance and notices Angel from the balcony. When he did this, his smile falters a bit and teleport away.

Niffty
As he watches the Extermination, Vox becomes amazed and impressed when Niffty stabs Adam to death.
