Carmilla Carmine

"♪ I always thought that I would keep blood off my face. But when that thing attacked, I had to act to cross that line and keep them safe. But if anyone knew, then all of Hell would rise to war. And who's to say who'd survive the fray? I might lose the ones that I was killing for. So I, I'll be your keeper. Do whatever it takes, I'll make the mistakes. I'll keep you safe and keep this secret. ♪"

- Carmilla Carmine, during "Whatever It Takes"

Carmilla Carmine is a demon and one of the many powerful Overlords of Hell. She controls Hell's weapon supplies.

Appearance
Carmella is a humanoid demon with gray skin, white hair with black streaks formed in the shape of two large horns, and red eyes with white irises. She has a patch around her eyes that appears to be either a mask or skin. Her hands are rather large in proportion to her body. Her attire is reminiscent of a ballerina, wearing a black dress with white stripes at the rim of the skirt and pink underneath, and black stockings covered by white ballerina shoelaces. She wears a pair of metallic ballet shoes she walks on at the tips of her toes.

Personality
Carmilla Carmine appears to be largely professional, though she can lose her temper, especially when Zestial is insulted or her family is in danger. This is in comparison to Zestial, who presents as very level-headed and equable.

She cares about her daughters, willing to cross any line to protect them, even if it means killing an Exorcist while knowing all sorts of disastrous consequences for it.

History
While not much is known about Carmilla's past, she oversees weapon collection and management along with her daughters. Odette and Clara work under their mother in her business as Hell's top arms dealer. During the previous extermination, Odette collects leftover angelic weapons and both her and Clara deliver their mother's products to Sinners who purchase them. Her daughters also shown to work in the capacity of their mother's personal assistants, as shown where they all attend the meeting she arranged between fellow Overlords and assisted her in her presentation regarding the Extermination’s effect on Hell's populace and how it affects them.

Abilities

 * Combat prowess - She was able to kill an exorcist, presumably with a blessing-tipped weapon.

Skillset

 * Technological knowledge - Due to having a business selling weaponry and technology, she appears to have a vast level of knowledge regarding technology.
 * Musical talent - She is capable of singing.
 * Leadership - She appears to be the de facto head of the Board of Overlords.

Trivia

 * Out of the Overlords, Carmella has the closest relationship with Zestial. This may suggest the two are in a relationship, given by her defending him in song, and revealing her killing of an exorcist to him.
 * Given she has her two daughters, it is unknown what type of demon she is, as officially, Sinners cannot reproduce.
 * She is, potentially, the only overlord from Hazbin Hotel to be connected to the spin-off series Helluva Boss specifically in the episode "The Harvest Moon Festival". Though it is unknown whether Carmilla is responsible for creating a carmine weapon.
