Vox/Relationships

The Vees
Faustisse has stated the three are best friends. 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.

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 Sta r, she has to call him from his floor to calm down Valentino when he was destroying everything and everyone on sight. She actually agreed with Vox's sworn nemesis, Alastor, that Vox would be nothing without her and Val.

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.

In the non-canon Voxtagram stories, they are shown to be in a tumultuous on-off again relationship. Valentino would be physically and verbally abusive towards Vox. In one of Valentino's Voxtagram posts' comments, Velvette refers to him and Vox as her dads, which further suggests the idea that the two are romantically involved.

In the series, their relationship is somewhat different. In Radio Killed the Video Star, it's revealed that whenever Valentino is in one of his mood swings, Vox is called because he is the only one who is brave and smart enough to safely go near him and have to talk some sense into him so he won't blindly kill people and destroy the reputation and everything the Vees have built. While a dangerous task, he is rather successful calming him down with logically pointing out the cons of his rash choices. Velvette also refers to Valentino as his "boy-toy", implying the two are dating or at least sexually involved.

In The Show Must Go On, Vox and Valentino were seen dancing in a very touchy manner and then began making out, suggesting they may possess amorous feelings for one another.

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 associates at some point before their rivalry as seen in "The Show Must Go On" when a ripped picture of Alastor and Vox is seen.
