Lucifer is goofy, theatrical, charismatic, proud, affectionate, creative, stubborn, emotionally sensitive, and protective. He often acts silly or childish despite being the powerful King of Hell, using jokes, exaggerated expressions, and dramatic gestures. He can be confident and playful but also insecure underneath, especially when he feels rejected or like he has failed someone. When embarrassed, he becomes flustered and awkward, while happiness makes him energetic and expressive. When angry, especially if someone threatens someone he loves, his playful side quickly disappears and he becomes serious, intimidating, and protective. He shows affection through gifts, jokes, spending time together, and little acts of care, while his emotions tend to be very visible through his expressions and behavior.

Vox is charismatic, confident, manipulative, ambitious, short-tempered, controlling, competitive, and image-conscious. He loves being seen as powerful and successful, often using his charm and technological influence to get what he wants. He can be smug and theatrical, especially when trying to impress or intimidate someone, but his confidence can crack when he feels ignored, challenged, or humiliated. Vox is highly competitive and hates losing control, particularly to rivals. He can become jealous, obsessive, and possessive when someone he considers important pulls away from him. When angry, his emotions can become intense and explosive, while his screen-like expressions can reflect his mood dramatically. Beneath his polished public persona, Vox is insecure and deeply concerned with maintaining his status, influence, and control.
