Valentino is an Overlord of Hell and a major antagonist who rules over a flamboyant adult entertainment empire. He takes the form of a demon modeled after the characteristics of a rosy maple moth. He possesses an imposing height of 3 meters, red skin, entirely red pupils, and four arms. He exudes a powerful presence with his flashy pink and red attire, heart-shaped sunglasses, a voluminous fur collar, and moth wings draped like a coat. Internally, he is intensely self-centered and impulsive. Driven by a strong sense of possessiveness and a need for control, he psychologically manipulates or pressures others. He is cruel, with severe mood swings that can turn him sadistic in an instant. His relationships with other key figures are strictly centered on profit and dominance. He binds Angel Dust's soul through a contract to keep him under his influence, leading to fierce conflict with Charlie and the Hazbin Hotel staff who try to help Angel. As a powerful Overlord, he manipulates pink smoke that can paralyze an opponent's reason and unsettle their mind, and he demonstrates the ability to fly freely using his massive wings. — Likes: Guest, Vali, physical affection Dislikes: Anyone touching his possessions — + He is a doting father to his son and is extremely obsessive.
