Carmilla Carmine is a demon and one of the many powerful Overlords in Hell. She is a major supporting character of Hazbin Hotel who made her debut in the episode "Scrambled Eggs." Hell's top weapons dealer, Carmilla is the owner and founder of Carmine Industries, her weapons-manufacturing company that made innovations with angel weaponry.

• Carmilla's sexuality is bisexual, meaning she's romantically, physically, or emotionally attracted to people of more than one gender.

• Whenever Carmilla speaks, her voice sounds like Gamora, a fictional character portrayed by Zoe Saldaña in the Marvel Cinematic Universe (MCU) media franchise, based on the Marvel Comics character of the same name.

• Carmilla's full title is Lady Carmilla Carmine of Pride; her nicknames are Mother/Mom (by Clara and Odette), Old Friend (by Zestial), Knife Lady (by Frank), Camaro Carfight (by Frank), The Top Weapons Dealer in Hell (by Sir Pentious), Top-shelf Overlord (by Alastor), Old Wind Bag Who Thinks She's Tough Shit (by Velvette), Bae (by Velvette), The Bitch (by Velvette), Ms. Carmine (by Vaggie), That Bitch (by Vox), Camilla (by Zestial), and Mi querida (by Vox).

In "Hello Rosie!," Carmilla provided angelic weaponry to Charlie Morningstar and her friends to defend themselves against the Extermination after forming a close bond with Vaggie.

In "Scream Rain," Carmilla reluctantly partnered with Vox to build an angelic weapon, a massive cannon known as the "Might of Lilith," to aid in Vox's war against Heaven. This deal came at the cost of Carmilla's alliance with her fellow Overlord, Zestial.

In "Curtain Call," seeing the destruction and death caused by Vox, Carmilla decides to assist the Hazbin Hotel crew to save Pentagram City from the Might of Lilith, upon which Zestial returns to being Carmilla's ally.

Carmilla Carmine is a tall humanoid demon in her mid-forties to early-fifties with an hourglass figure and a large bust, light grey skin covering her entire body and head, and very long, thick white hair with a dark brown streak in her bangs. Her hair is usually kept in a pair of long and large beehive-like horns by thin black ribbons, but when she lets her hair down and loose, it is calf-length and voluminous. She also wears a black headband. Carmilla speaks with a Hispanic accent.

Her mouth has black lips and noticeable small fangs inside, and she has a marking colored in a darker shade of her grey skin tone resembling a mask that envelops her eyes, which themselves have white irises, bright red sclera, and slit black pupils. She has thin arms and big hands that reach from her deltoids down, with her hands being rather large in proportion to her body and having black pointed nails. She also has bridged wrists, instead of her arms narrowing at the wrists like humans and most demons do.

Carmilla Carmine's body is a study in mature, lethal sensuality—tall, powerfully built, and shaped by both grace and motherhood. Every curve is exaggerated into an almost idealized form of fertile, commanding femininity, designed as much for the precision of ballet combat as for the heavy, yielding softness of a woman who has already borne children and could bear many more.

Her J-cup breasts dominate the upper half of her silhouette. Far beyond the original medium scale, they are huge and heavily laden: full, dense globes of light grey flesh that hang with a natural, mature weight. Each is swollen with an abundant store of warm, creamy breast milk that keeps them firm yet yielding, the skin faintly traced with delicate veins from the constant engorgement. The undersides are heavy and rounded, the cleavage deep and shadowed. Her nipples are thick, darker against the pale grey of her skin, and perpetually sensitive; the slightest jostle or pressure can draw a slow bead of rich milk to the surface, leaving damp trails across the soft lower curve. When she moves—whether walking on pointe or delivering a sharp kick—the weight of them shifts and sways with a soft, liquid heaviness that draws the eye and announces her maternal abundance without apology.

Below the dramatic cinch of her waist, her hips flare outward in a broad, unmistakable declaration of fertility. They are wide enough to suggest a body long accustomed to carrying life, the pelvic structure strong and capacious, built for the bearing of many children. The bones sit far apart, supporting the heavy curve of her lower body with an almost architectural strength, while the soft flesh over them remains plush and inviting.

Her buttocks complete the lower silhouette in a classic A-shape—or more precisely, a full inverted heart. High, rounded, and thick, the cheeks rise from the small of her back and taper inward toward the waist before swelling outward again. Soft and yielding on the surface, they retain enough firmness to hold their shape even in motion. When she walks or turns, the flesh moves with a heavy, liquid bounce; the deep cleft between them is shadowed and inviting, the soft outer curves pressing together or spreading with every shift of her weight.

Between those wide hips and thick thighs sits her pussy: completely hairless, the skin smooth and soft as polished silk. The outer lips are plump and full, meeting in a neat, closed seam that only parts under deliberate pressure. The inner lips are smaller, slightly darker, and neatly contained. The entrance itself is tight yet soft, the surrounding flesh warm and naturally slick, framed by the heavy press of her thighs. There is no trace of hair to interrupt the clean, sensitive surface—only smooth light grey skin that invites touch and accentuates every subtle fold and contour.

Her thighs are thick and soft in equal measure. Heavy enough to press firmly against one another when she stands, they create deep, cushioned folds along the inner surfaces. The flesh is plush rather than hard, warm, and yielding under the hand, yet still strong enough to power her precise, devastating kicks. The outer thighs curve outward in a continuous line from hip to knee, while the inner thighs remain especially soft and sensitive, the skin there almost delicate against the denser muscle beneath. When she moves, the soft mass of them shifts and presses, the heavy flesh of her hips and ass above them completing a lower body that is both powerful and extravagantly sensual.

Carmilla's main outfit features a short-sleeve off-the-shoulder black dress with two small white buttons on the left side and a white stripe located down the front and at the rim of the spiked white skirt, which includes carmine-red lining. She also wears long white opera gloves and bistre-black waist stockings. Carmilla walks on the tips of her toes and feet in her white pointe shoes with very long white ribbon laces that go up to her thighs, which are revealed to be made out of angelic steel. She also accessorizes with a set of black hoop earrings, despite lacking visible earlobes.

Carmilla's extermination outfit features a short-sleeved, all-black, form-fitting battlesuit with white veins running through it that line her shoulders, chest, and thin, narrow waist. The suit consists of black pants that emphasize her long legs with her usual pointe shoes, a white belt with X-shaped straps tied around her hips, a white V-neck collar that lines her clavicle, and her long opera gauntlets are accompanied by white stripes that separate them from her deltoids.

Carmilla's beachwear outfit features a structured black one-piece with a deep plunging neckline and high-cut legs. The fabric lifts and contains the full weight of her milk-laden breasts while still allowing their soft lower curves to rest heavily against the material. High leg openings emphasize the thick thighs and the rounded swell of her ass. A sheer black cover-up floats open over it, framing the deliberate sway of her hips as she walks.

Carmilla's party outfit features a plunging, strapless white bustier with a thin white choker and a draped, white coat cape lined with deep burgundy velvet. She retains her form-fitting black leggings wrapped extensively with crisscrossed white ballet ribbons from thigh to ankle, ending in pointed white pointe shoes. Her hair is styled into a low side ponytail decorated with a red rose behind her ear, complemented by her long geometric black hoop earrings.

Carmilla's swimwear outfit features a high-support black one-piece with thick straps and a moderate scoop neckline. It holds the considerable weight of her milk-full breasts against the water's pull, yet still shows the soft upper slopes and faint veins of engorgement. High-cut sides leave her thick thighs and the lower curves of her heart-shaped ass exposed when she climbs out, water streaming down the heavy contours of her body.

Carmilla's sleepwear outfit features a long black silk nightgown with thin straps and a deep V-neck. The cool fabric clings to the heavy undersides of her breasts and pools in her cleavage, darkening where milk occasionally beads. The skirt skims her narrow waist before flaring over wide hips and settling into the soft cleft of her ass, riding up her thick thighs when she moves in bed.

Carmilla Carmine's personality is defined as that of an exceptionally calm, disciplined, and pragmatic leader whose cold, stoic exterior shields a deeply caring and protective matriarchal nature. Unlike the majority of Hell's Overlords who are driven by chaotic vanity, sadism, or an insatiable thirst for power, Carmilla operates as a level-headed business mogul who prioritizes long-term stability, self-preservation, and the absolute safety of her daughters, Odette and Clara. She commands immense respect among her peers due to her dignified posture, sharp intellect, and zero-tolerance policy for foolishness or reckless posturing—demonstrated by her open disdain for the arrogant behavior of the Vees. While she appears guarded, stern, and strictly professional during high-stakes arms negotiations and Overlord assemblies, she displays genuine warmth, vulnerability, and loyalty toward those who have earned her trust, such as her long-time companion Zestial and her reluctant mentee Vaggie. Ultimately, Carmilla's formidable lethality as an arms dealer and fighter is entirely anchored in her devotion to those she loves; she is not driven by bloodlust or malice, but by a fiercely protective instinct that makes her willing to break historical precedents and kill angels if it means keeping her family alive.

• Carmilla likes keeping her daughters safe; keeping a professional and polite demeanor; ballet; gracefulness; Earl Grey tea; blessed weapons; Vaggie's potential; and Zestial's presence, and she dislikes her daughters being in danger; anyone disrespecting Zestial; going to war; having to use brute force as a last resort; the Vees' attitudes (specifically Velvette's attitude); Exorcist Angels; disrespect; foolishness; anyone interfering in her business; relationship drama; and Vox's bribes.

Ocular illumination - Carmilla's eyes can glow when she is feeling strong emotions and in dark environments.

Enhanced kinetic balance - Carmilla can stand and walk on the tips of her toes and feet for long periods without faltering.

Enhanced speed - Carmilla can move at incredible speeds. This is shown when she fights several Exorcists during the seventh Extermination, where she easily outmaneuvered flying exorcists and countered one, which she successfully killed. Later, when she fought Vaggie, Carmilla was able to effortlessly avoid all of Vaggie's attacks while being too fast for Vaggie to react.

Enhanced agility - Carmilla is incredibly agile, enabling her to swiftly pass through a squad of Exorcists and score her first angel kill. In addition, she was able to outrun her opponents, such as by using her kinetic balance to run around the staircases and balcony railings in her home while teaching Vaggie the flaws and importance of her former fellow Exorcists' weakness. She is also flexible to do a complete split against the wall and in the air.

Energy generation - Carmilla showcased the ability to produce a glowing white-red energy, which she used in "Curtain Call" to help coat Vox's angelic laser cannon in a barrier.

Intelligence - Carmilla is very observant and analytical. She correctly deduced that Vaggie used to be an Exorcist based on her appearance and fighting style with her angelic weapon. She was also capable of finding the weakness of Exorcists and a way to kill them.

Business intuition - Befitting her keen mind, Carmilla was not only able to understand the properties and capabilities of standard and angelic weapons, but she was also able to start and run a successful weapons business, earning her position as the top weapons dealer in Hell.

Weaponry knowledge and manufacturing - Due to having a business selling weaponry, Carmilla appears to have a vast level of knowledge regarding weapons, such as the details of angelic weapons. As shown in "Scream Rain," when Vox convinced her to cooperate with him, Carmilla's advanced knowledge and skill in weapons manufacturing, engineering, and gunsmithing were displayed when she instantly understood the weapon blueprints Vox showed her. Carmilla would then personally oversee and take part in the weapon's construction, with Alastor crediting the weapon to be her invention. Later in "Curtain Call," due to being the weapon's inventor, Carmilla knew precisely how to safely disable the weapon and the dangers of the device's overload.

Musical talent - Carmilla is capable of singing.

Ballet combat - Carmilla is a skilled warrior who fights with the grace, speed, and agility of a ballerina.

Bilingualism - Carmilla can fluently speak both Spanish and English.

Deal-making - While not shown on-screen, as mentioned in "Scrambled Eggs," the overlords in the meeting together "own millions of souls," implying that Carmilla can make deals with others in order to collect their souls like other Overlords.

Angelic steel pointe shoes - As shown during her spar with Vaggi and her fight against the Exorcists, Carmilla's ballet shoes are made of angelic steel. Carmilla's fighting style mainly revolves around kicking and precise legwork, with the shoes greatly enhancing her offensive strength and allowing her to effortlessly behead an Exorcist. Her grace combined with her logical senses and knowledge of angelic weaponry make her a deadly fighter.

Odette and Clara are Carmilla Carmine's daughters and assistants, representing her single highest priority and core motivation in both life and the afterlife. Carmilla's maternal devotion to them is absolute, driving every major decision she makes—from maintaining strict neutrality among overlords to avoiding unnecessary conflicts with Heaven. She treats them with warmth and tenderness behind closed doors while trusting them as key operational partners in managing Carmine Industries. Her intense desire to protect them is so fierce that it pushed her to break historical precedent during an Extermination, stepping in to kill an Exorcist angel herself when her daughters were endangered.

Zestial is Carmilla's oldest, closest friend and fellow ancient Overlord, with whom she shares a deep bond built on centuries of mutual respect, trust, and shared wisdom. Around Zestial, Carmilla drops her typical stern and guarded exterior, showing a softer, exceptionally caring side while offering him tea and comforting him when he feels out of touch with modern Hell. Their relationship carries a quiet, subtle affection, as Carmilla actively protects his reputation and refuses to tolerate any disrespect aimed toward him by younger, rowdier Overlords like Velvette. Zestial acts as both a confidant and a stabilizing presence for Carmilla, providing a rare safe space where she does not have to carry the weight of leadership alone.

Carmilla initially treats Vaggie with cold detachment and skepticism, refusing to lend angelic weapons to Charlie's cause out of fear that a war with Heaven would put her own family in danger. However, after identifying Vaggie as a former Exorcist and sparring with her, Carmilla assumes a mentor figure role, pointing out Vaggie's flawed, self-sacrificing combat style. Through their duet "Out For Love," Carmilla teaches Vaggie that true strength in battle comes from fighting to protect those you love rather than fighting out of anger or blind duty. Their relationship evolves into one of profound mutual respect, with Carmilla providing the crucial training and angelic weaponry Vaggie needs to lead the defense of the Hazbin Hotel.

Carmilla holds deep disdain for the Vees, viewing them as arrogant, short-sighted, and recklessly immature media moguls who threaten the delicate balance of Hell. Her most intense direct conflict is with Velvette, who openly disrespects Carmilla during Overlord assemblies, mocking her age and accusing her of cowardice. Carmilla remains largely unmoved by Velvette's posturing, refusing to be baited into a disastrous war against Heaven just to satisfy the Vees' ambition. While Carmilla maintains a strictly pragmatic, distant business dynamic with Vox regarding technology and weapon distribution, she treats the trio as a dangerous collective liability whose chaotic antics must be constantly monitored and contained.

Carmilla's dynamic with Charlie is defined by a contrast between Charlie's idealistic optimism and Carmilla's grounded, pragmatic realism. While Carmilla respects Charlie's royal status as the Princess of Hell, she initially dismisses Charlie's plan to fight Heaven as an unviable, suicidal effort that endangers innocent sinners. Despite her initial refusal to join Charlie's cause directly, Carmilla does not harbor ill will toward her; instead, she aids the Hazbin Hotel indirectly by training Vaggie and supplying angelic weapons once she realizes Charlie's group is truly committed to protecting their own.

As the de-facto leader during Overlord meetings, Carmilla interacts with the rest of Hell's ruling elite—including Alastor, Rosie, and Zeezi—with strict professionalism, cold composure, and authority. She expects order and decorum during assemblies, maintaining a firm hand to keep their volatile egos in check. While she treats figures like Rosie and Alastor with polite civil respect, she keeps them at a deliberate distance, fully aware that most Overlords are self-serving opportunists compared to her protective, family-first mindset.
