Asmodeus (Helluva Boss)

Demons are a catch-all term for any entity that resides in Hell. Demons can range from unique and sapient species, such as imps or succubi and non-sapient fauna species, to more disparate and non-singular groups, such as Sinners, which represent less of a unique species and more of a disparate collection of incompatible mixtures of different entities. Demons come in all shapes and sizes.

Their physical forms typically have characteristics associated with the human body, except for having human ears and sometimes a lack of a nose.

Culture Demon society follows cultural lines that are similar to those of humanity in some regards. There are laws that are upheld, facilities that provide goods and services (shops, news stations, bars, etc.), and emergency services such as fire departments.

Technological developments in Hell appear to mirror those on Earth, albeit with a twisted and demonic influence on the design outcome. However, some of Hell's technological developments, specifically weapons technology, have also been influenced and inspired by angelic technology to some unknown degree, which changed the face of Hell combat and led to the development of "blessing" Hell weapons (such as the Carmine-Crafted Blessing-Tipped Rifle used in "The Harvest Moon Festival" and the Blessed Rope used in "Western Energy"), similar to Exorcist weaponry, which can kill even Demon Royalty.

While demon society is very diverse, it can be somewhat divided into two distinct groups in Hell - Sinners and Hellborns. There are also Fallen Angels in Hell, however, Lucifer Morningstar is the only known Fallen Angel.

Most demons also have a somewhat questionable moral compass.

Hell has seven rings, however for reasons or methods unknown, sinners are unable to leave the Pride Ring, and thus are entirely present only in that ring. Hellborn, which applies to all demon species born in Hell, can be found in all seven rings of Hell and can freely travel across any and all of the rings. Charlie and Lucifer are also able to travel the rings of Hell as well.

As revealed in "Overture" by Lute, in regards to the annual Extermination by Heaven to cull Hell's overpopulation, Hellborn demons have been pardoned from the massacre as per the negotiation with Lucifer Morningstar, only allowing Sinners to be targeted and killed by the Exorcists.

As Hellborn demons were never human, nor did they ever live on Earth, they have no experience of humanity or the human world. In spite of this, Hellborns make ready usage of human inspired/derived technology and cultural norms.

Hierarchy Demons of Hell are governed by a crude form of hierarchy, in which one's position in the hierarchy is determined purely by the strength of the individual, and it is dominated by Lucifer, a Fallen Angel, above all other demons (even the likes of Satan and Beelzebub). This hierarchy is roughly divided into tiers; going top-to-bottom, it is as follows:

Lucifer - The King of Hell and the Sin of Pride Charlie - The Princess of Hell, heir apparent to Hell's throne The Seven Deadly Sins - Demons who embody one of the seven deadly sins The Ars Goetia - Hellborn Demons with royal status, including Prince Stolas Overlords - Demons who wield considerable power Sinners - Immortal Demons who were once humans on Earth, having sinned were damned to Hell Hellborn demons - Succubi, Incubi, and other species of demons native to Hell Imps and Hellhounds - The bottom of Hell's society The existence of the tiers demonstrate exceptions to the hierarchy system. The first being that a demon's status is treated variably. For instance, Charlie, despite being the second-highest-ranking demon, is not respected by the populace due to their spiteful climate, and her unwillingness to use any of her strength against them. Rather, respect is dependent on the power and intimidation of one's character, like in Lucifer's case.

In this hierarchy, Imps and Hellhounds as the lowest ranked are generally expected to do jobs in service to the higher ranked demons, and in the case of imps are sometimes viewed as "unemployed rabble". It is generally frowned upon for nobility and royalty to sleep with an imp, while some imps, like Striker, view Blitzo and Fizzarolli as embarrassments to imp-kind for having relations with "blue-bloods", such as Stolas and Asmodeus. Due to their low ranking, Hellhounds have to wait five years to get their Hellbies shot which should be done annually.

Sinners are unique in that they can elevate their status by accumulating powers, which they receive by making deals, soul dealing, or even taking it by force. These beings, colloquially known as Overlords, could theoretically rival higher-ranking Hellborn demons or even royalty of Hell, although the royalty would still be considered above them.[11] Overlords typically obtain or enhance their powers by making deals with other demons, as well as dominating them in battle and taking in their dark energy.

While there has never been mention of demons practicing any form of spiritualism or religion, many characters have been seen cursing by Satan's name in lieu of God, which is later confirmed in a stream by Vivienne Medrano that imps view Satan as a deity-like figure, implying there are some sort of belief systems or revering attitudes in Hell, at least with Satan.

Additionally, in Hell demons treat Krampus like Santa Claus, viewing him like a good figure, and eagerly await Krampus' arrival. She also mentioned that like how Krampus is the negative contrast to Santa on Earth, there is a negative contrast to Krampus in Hell as well.

Language Demons are known to possess their own languages, similar to humanity, as revealed when Charlie is stated to be fluent in every demon language she has learned while growing up. However the majority of demons seemingly speak a form of English, which has been referred to as "Satan's plain English". Humans are capable of understanding and conversing with demons and vice versa with no apparent difficulty.

The only other non-English language that has been communicated in either shows, so far, has been Spanish by Vaggie, Valentino, and Carmilla Carmine, and broken Italian by Fizzarolli.

Cultural Relations Some Angels, such as the cherubs and exorcists, view themselves as holier and more worthy of existence than Demons under the presumption that all Demons -Sinner or Hellborn- are unholy and incapable of goodness.

Biology Appearance Demons tend to have an overarching theme to their design, typically Hellborn species have very consistent appearances and biological designs according to their species, whereas Sinners can have extremely diverse appearances, capable of looking like anything. Sinners can resemble animals (some more so than others), objects (such as Vox appearing as a television, some gun-esque demons, or even inanimate objects such as couches), humanoid, and more, appearing in a wide array of colors, appearances, sizes, and structures based on what creature their character is based on. Hellborn demons appear more monstrous and non-human, whereas demons that appear more humanoid-looking, such as Lucifer and Charlie, are actually quite rare.

As some Sinners can manifest in non-biological forms, such as televisions, furniture, and akin, it is possible that some form of magic can allow these Sinners to function in spite of the lack of a biologically functional body. Hellborns are born with fully functional biological bodies and internal anatomy.

Some demons, particularly Sinners and higher ranking Hellborns, are able to alter parts of themselves at will, such as gaining an extra or new set of appendages such as extra pairs of eyes, horns, limbs, or simply can enhance parts of their default form's body parts, such as the rest of Charlie's teeth becoming pointed fangs. This is referred to as a "full demon" form for sinners and certain Hellborn, and usually appears during periods of intense anger or other emotions.
