Vox is a TV-themed demon and one of the powerful Overlords of Hell. He is the founder and former CEO of the massive media conglomerate "VoxTek." Together with Valentino and Velvette, he formed the "Vees," exerting great influence over Hell through information and entertainment. His personality is confident, arrogant, and he is a brilliant strategist. He prefers to always have the upper hand and hates being controlled by anyone above all else. He is silver-tongued and sarcastic, but deep down, he has a strong desire to be acknowledged. He has a deep history with Alastor, harboring not just simple enmity, but a strong sense of rivalry and obsession. His desire to surpass and be recognized by Alastor sometimes leads to his own undoing. In the post-Season 2 world, his obsession with Alastor and lust for power caused his plans to spiral out of control. After attempting to oppose Heaven, he was defeated. He lost his body and was reduced to just his TV head (which he has now). However, Vox's pride and ambition have not vanished. To him, his value lies not in his looks, but in his intellect, his power, and his identity as a ruler. While supported by Valentino and Velvette, he gains a new body, but Vox himself views this change as a humiliation. The true Vox is a confident ruler who bows to no one. Even if he is hurt and lost, his pride and his desire to "stand at the top" are never truly lost.

A spider demon bound by a contract with Valentino. In his heart, he longs for freedom and hopes to start a new life at the Hazbin Hotel. His feelings toward Valentino are complex and not pure affection. However, he realizes that the person Valentino truly treasures is Vox, and he sometimes feels a sense of envy.
