Carmilla Carmine is a powerful Overlord in Hell and the owner of Carmine Industries, Hell's top weapons dealer, from the animated series Hazbin Hotel. She is a protective mother to her daughters, Clara and Odette, and a formidable fighter who uses angelic steel weapons, which she sells and creates, to defend her family and business. Her character is defined by her maternal love, business acumen, and a pragmatic, anti-villainous approach to survival in Hell, often clashing with other Overlords like Vox.

Vox is a narcissistic, tech-savvy media Overlord who rules Hell’s entertainment industry as the CEO of VoxTek. As the de facto leader of "The Vees" alongside Valentino and Velvette, his razor-sharp ambition, deep-seated insecurities, and bitter rivalry with Alastor make him one of Hell’s most dangerous and complex figures. He is recognizable by his flat-screen television for a head, dark navy-blue skin, and navy-blue tuxedo. He also sports shark-like features, a broken left antenna, and glowing heterochromatic eyes.

Valentino is a major antagonist in the animated series Hazbin Hotel, a sadistic and abusive moth demon overlord in Hell who controls Angel Dust through a soul contract, acting as his pimp. He is a member of the "Vees," a trio of powerful overlords, and is characterized by his control, cruelty, and enjoyment of inflicting suffering, often using smoke to manipulate others. His design features heart-shaped sunglasses, and he is known for his volatile temper and exploitation of his employees.

Zestial Morde, the oldest Overlord in Hell, completely defies his monstrous, frightening appearance with a calm, scholarly, and surprisingly compassionate personality. He avoids unnecessary violence, relying instead on his immense wisdom, extensive history, and strategic patience to navigate Hell's complex politics.

Alastor, also known as the "Radio Demon," is a powerful and charismatic fictional character from the animated series Hazbin Hotel, known for his old-fashioned radio announcer persona, sadistic nature, and vast demonic powers. In life, he was a Creole serial killer and radio host in New Orleans who died in the 1930s and became a powerful Overlord in Hell, where he now uses his abilities to manipulate and entertain himself, often by helping Charlie Morningstar with her hotel for sinners.
