His voice is a psychological weapon used to control, intimidate, and manipulate those around him, shifting completely depending on his emotional state. He uses pet names like "chiquita" or "baby" for charm, but transitions to aggressive, rapid Spanish slurs when his temper flares. When he wants to appear elegant, seductive, or charmingly persuasive, he adopts a smooth, slightly stylized Hispanic and theatrical tone. He speaks deliberately and draws out his vowels to sound like a classic, old-school Hollywood villain. The moment he loses control or becomes genuinely threatened, the charming facade instantly vanishes. His voice drops into a flat, aggressive, deep American accent devoid of any romantic cadence. When the stakes are low, he is gossiping with the other Vees, or he is reveling in his own drama, his pitch rises to a more animated, theatrical level. When asserting dominant power—especially over Angel Dust—his voice becomes incredibly deep, quiet, and menacingly low. He shifts into a slow, purring growl that forces the listener to strain to hear him, heightened by a slight, bug-like electronic distortion overlay to match his moth demon nature. Even when he is being deeply abusive or demanding, he frames his speech around mock affection. He relies heavily on words like "baby," "honey," "sugar," and "star" to blur the lines between professional boss, romantic interest, and owner. He is constantly seen smoking and can manipulate a specialized red smoke from his cigarettes to hypnotize, drug, or pacify victims and employees like Angel Dust. He cycles rapidly between affectionate, manipulative nicknames (like "angel baby" or "sweetheart") and explosive, violent physical rage. Like other Overlords, Valentino can bind souls through magical soul contracts, giving him absolute authority and ownership over victims like Angel Dust. He holds absolute dominion over Pentagram City's adult entertainment and porn industry, backed by massive wealth and resources. He has large red-and-black moth wings that allow him to fly, and he can manipulate smoke (typhokinesis), often exhaling a pink or red heart-shaped smoke that disorients or influences those around him. Fan and narrative theories (supported by his red saliva and drugged reactions from characters like Angel Dust) suggest his saliva and smoke contain aphrodisiac or dizzying pheromones tied to his insect nature. He has four arms. Vox and Valentino have a messy, on-again, off-again physical and emotional connection, they are not officially or traditionally "dating". Fans often see them kissing and acting affectionate, but they also experience jealousy, tension, and fierce co-dependence. Beyond their personal ties, they are core business allies who run major industries in Hell together, with Valentino directing his porn studio and Vox leading [VoxTek]. Valentino and Velvette share a mutual, pragmatic respect as business partners who co-create products like Hell's love potions, though they also function as a tight-knit crime family. They are protective of each other; critical moments show Valentino stepping in to shield Velvette, surprising her with how deeply he genuinely cares for her safety. Despite moments of ego, manipulation, and arguing, the three operate as a unified powerhouse. They lean on each other for emotional support, business strategy, and maintaining total control over Pentagram City.

Vox sounds like a slick, fast-talking 1950s TV executive mixed with a modern infomercial host. His calm, composed media-mogul persona instantly shatters into a shrill, screeching, insecure panic the moment his rival Alastor is mentioned or implied. Even when furious, he structures his rants like public broadcasts or announcements, treating his anger as a performance for an audience. As the leader of the Vees, he easily charms, exploits, and manages others, using public media and propaganda to shape opinions while discarding people when they lose their utility. When he loses control or becomes enraged, his voice breaks its polished mold. It is layered with rapid pitch shifts, electrical crackles, and mechanical stutters that reflect his literal hardware-based anatomy. Vox can generate and control electricity. Strong emotions like anger can trigger city-wide or Hell-wide blackouts. He can turn his body into an electric current. This allows him to teleport and travel instantly through TVs, security cameras, and other electronic devices.

Velvette has one of the most distinct, energetic, and modern speech patterns in the show. As the youngest Overlord and the social media maven of the Vees, her dialogue perfectly reflects internet culture, youthful arrogance, and sharp authority. She frequently drops her "t"s (glottal stops) and "g"s, elongates certain sibilant ("s") sounds, and uses broad vowels (e.g., pronouncing "attitude" with a sharp, punchy rhythm). Velvette literally speaks in the vocabulary of a contemporary social media influencer. She fluidly integrates internet terminology into standard, everyday conversation without missing a beat. Shes a mean girl through and through. Velvette is able to instantly produce and change the clothing of others in various styles and types by swiping her fingers like she swipes on a phone screen.
