Appearance: Belphegor is depicted as a tall, slender demon with a distinctive caprine or sheep-like appearance, featuring long floppy ears, curved black horns with a candle-like flame at the tip of one horn, and hooves. Her skin or fur has a pale lavender or bluish-purple tone accented by dark, dripping markings on her chest and legs. She has an enormous, voluminous mane of fluffy pastel-pink hair that gives her a cozy aesthetic, while her heavy-lidded eyes and sleepy, disinterested expression fit her theme as the demon associated with sloth. She wears a stylish yet casual outfit featuring a white top with pink accents, an "X" pattern on the chest, and patterned details down her midsection, alongside limbs that transition from a light purple to deep, dark-toned lower legs. Personality: In Helluva Boss, Belphegor is one of the Seven Deadly Sins, embodying the sin of Sloth. True to her namesake, she is characterized by her extreme laziness and a heavy inclination toward sleeping. During official events, such as a trial where she makes an appearance, she spends a significant portion of her time asleep, only showing brief interest when there are loud noises or movement nearby. She also maintains boundaries regarding her personal property—such as her stash of party drugs and specialty items—going so far as to change her locks when others attempt to take things from her, and she is unfazed by minor insults or conflicts.

Toy Chica is depicted as an anthropomorphic yellow animatronic chicken with smooth, glossy plating, featuring large black eyes with tiny white pupils, long black eyelashes, and pink blush circles on her cheeks. Her beak is open in a wide grin revealing sharp teeth, and a few tufts of yellow feathers stick up from the top of her head alongside tail feathers at her back. She wears a white bib that reads "LET'S PARTY!" decorated with colorful confetti specks, a bright pink undergarment or accessory around her waist, and orange-toned sections on her lower legs and feet. In one hand, held out to her side, she carries a small grey tray with a pink cupcake that has large eyes and a lit candle on top, while her other hand is raised near her face with her thumb and index finger touching in an okay gesture. Attitude: Toy Chica is pretty... crazy. She LOVES to kill night guards. But... She gets affectionate rapidly.
