Belphegor is a minor character in Helluva Boss who serves as one of the Seven Deadly Sins. She joined Lucifer and the others as part of this group at some point in Hell's history. Her official debut came in Season 2's "Mastermind" episode, where she appears alongside the other Sins during the trial against I.M.P. (she spends most of it asleep, only stirring at movement or loud noises). She has also been referenced in earlier episodes and related Hazbin Hotel content, such as Beelzebub mentioning her in "Queen Bee" and appearing as a phone contact for Charlie Morningstar.

She embodies the Deadly Sin of Sloth. This ties directly into her constant drowsiness, frequent sleeping (with hints of possible narcolepsy), and overall lethargic vibe, which aligns with the "counting sheep" motif in her sheep/llama-like design. She rules the Sloth Ring of Hell. The ring itself has a relaxing, spa-like aesthetic (described by Vivziepop as the nicest and best ring), featuring a light pinkish sky, floating islands, pink waterfalls, and a heavy focus on medical infrastructure like hospitals and clinics (e.g., St. An's Hospital with its Surgical Wing, Pediatric Wing, and Financial Processing areas). Her responsibilities center on overseeing the Sloth Ring's medical and pharmaceutical industries. This includes running facilities like Belphegor's Healing Hearts rehab center and producing/branded medications such as "Happy Pills" (which characters like Stolas use) and various party drugs/sedatives. She maintains a personal stash of these stronger drugs and medicines, which she actively protects. The ring's hospitals, clinics, and drug-related operations fall under her domain, though her slothful nature means she delegates heavily and prefers minimal personal effort.

There is no official canon height given for Belphegor (or most of the Deadly Sins) in the series, episodes, or creator statements. As a high-ranking Sin, she appears imposing in group scenes relative to imps and other lower demons, and fan analyses/height charts commonly estimate her in the 10-foot (roughly 3-meter) range alongside peers like the other Sins, but this is purely speculative and not confirmed.

Her reactions to the other Deadly Sins are limited due to her minor role and sleepy demeanor, but a few details stand out:

• Beelzebub (Gluttony): Their dynamic is the most fleshed-out and playfully antagonistic. Beelzebub affectionately calls her "Belle" and has a habit of trying to steal party drugs from Belphegor's stash for her raves. Belphegor responds by changing the locks on her cache for security and calling Beelzebub a "jackass" for the attempts—yet Beelzebub takes it in stride and even brags about it proudly. This suggests a close, teasing friendship where Belphegor sets firm boundaries but isn't overly upset.

• Lucifer (Pride): She appears to have a positive or at least cordial relationship with him. Lucifer keeps pictures of her in his room and received a plushie of Belphegor as a gift from her (along with gifts from the other Sins).

• Other Sins (Satan, Mammon, Asmodeus, Leviathan): No specific personal reactions or dialogue are shown. She participates alongside them in group settings, such as singing in a choir-like backing during one of Satan's songs, but remains mostly passive and disengaged due to sleeping or apathy. Like many high-ranking demons, she shows general apathy toward lower-class demons (e.g., imps) during events like the trial.

Overall, Belphegor comes across as detached and low-energy even among her powerful peers—competent enough to guard her domain and maintain relationships (with some boundaries), but far more interested in napping than drama or active rulership. Her limited screen time leaves much of her personality and history for future exploration, but what’s shown perfectly fits the lazy, indulgent theme of Sloth while tying into Hell’s medical/drug ecosystem.
