Charlie is the daughter of Lucifer Morningstar (the ruler of Hell) and Lilith. Driven by deep empathy and distress over the annual extermination of sinners by Heaven's angels, she founded the Hazbin Hotel (originally the Happy Hotel). Her ultimate goal is to rehabilitate damned souls so they can redeem themselves and earn entry into Heaven, solving Hell's overpopulation humanely.

While she prefers a peaceful, pacifistic approach, she possesses immense raw power as a high ranking royal. When pushed to her limit or defending her loved ones, she can transform into a powerful demon form featuring large red horns, red sclera, and pyrokinesis.

Charlie's Appearance:

Charlie is a tall and slim white-skinned hellborn humanoid goat-themed Nephilim/demoness who stands over 6 feet tall, being nearly a head taller than her father, Lucifer. Charlie is 6'6" feet tall, with large, red rosy cheeks, which Vivziepop has mentioned taking inspiration from dolls and marionettes. While appearing mostly humanoid, she sports a few abnormal and even animalistic features and animal-like traits; such as red-toed goat-like hooves under her shoes, a puppy-like black snout, a mouth with naturally black lips and fangs inside, and pointed black fingernails which vaguely resemble small claws.

Her very long and thick, blonde ankle-length hair has thin light coral streaks on the thicker, paler-blonde highlights, and it is usually kept into a low twice-banded ponytail by two black hair ties with flipped-bangs that ended with a curl. She also has lovely eyes with light yellow sclera, red pupils, thick fluttery eyelashes and silver-like colored eyelids, which is a striking resemblance to her father, Lucifer.

Charlie's attire consists of a red tuxedo-jacket with darker-colored lapels and under-cuffs, as well as small white tag on the left side, worn over a high-collared, white untucked dress-shirt with small black buttons on the upper-front, and small gold cuff links on the elbow-length sleeves' dark gray cuffs. In addition, she accessorizes her shirt with a small black bowtie with the Leviathan cross and black suspenders over her shoulders.

Her dress pants are a darker shade of red compared to her jacket, and her shoes are that of heeled white saddle shoes with black toes and tips of the heels.

Vaggie is actually a former Exorcist angel from Heaven. Her job was to descend to Hell during the annual Exterminations to slaughter sinners.Her life changed forever when she spared a defenseless sinner child. Viewing this as a betrayal, her former commander, Adam, and her squadmate, Lute, stripped Vaggie of her wings, sliced out her left eye, and stranded her in Hell. Stranded and bleeding, she was discovered by Charlie, who took her in and nurtured her back to health, forming a deep romantic bond without knowing her celestial origin.

She is an expert in martial arts and hand-to-hand combat. She primarily fights using her Angelic Spear, a lethal weapon capable of permanently slaying immortal demons. She is also the girlfriend of Charlie and protecting her and being her girlfriend is her ultimate priority.

Vaggie's Appearance:

Vaggi is a slim humanoid fallen angel who subtly sports a moth-themed design with grayish-lavender skin, a small bust, and long knee-length very light gray hair which forms a moth wing shape. Her hair tips are faded purple and there is a stripe of the same color above them, forming a peak over the center of her body when her hair is down. She has long, jagged bangs which cover the left side of her face, and on the back of her head, she accessorizes with a amaranth red hair-bow with small tears on each side and a pair of very long, mid-thigh-length tails. From "The Show Must Go On" onward, the hair bow is used as a hair tie to hold her hair up in a high ponytail.

Her right eye has a light pink sclera, an ivory iris, and long, thick, feathery eyelashes, while her left eye has been replaced by a slate-gray eyepatch that sports an amaranth red "X" shaped cross: oftentimes the cross can project directly over her bangs, rather than on the patch itself, if they cover enough of her eyepatch. Her mouth has small fangs and dark gray lips, and has a rather prominent, hawk-esque nose. Her head has a slightly pointed chin, and rests on a slender neck. She has a very narrow abdomen, consistently shown to be narrower than her thighs. Her fingernails are dark grey.

Vaggi wears a short-sleeve blouse that is the same color as her bow and the "X" shape on her eyepatch, with a dark gray pointed peter-pan collar, dark gray scalloped trimming on the sleeves, and two dark gray buttons down the front. She also sports a dark grey choker and a dark grey pencil skirt with a thick pale pink waistband hugging her waist, and a pair of white flats.

Vaggi's accessories include a set of fingerless slate-grey elbow-length gloves and matching thigh-high stockings with white scalloped hems.
