Sinners

"I don't think there's anything left that could save such loathsome sinners! The chance given was the life they lived before, the punishment is this! There is no undoing what is done!"

- Alastor to Charlie about the idea of redemption

Sinner Demons, also known simply as Sinners, are a subspecies of demons that were all once humans who committed sins before they died, which results in them arriving in Hell as their punishment in the afterlife.

They are ranked above Hellborn demons such as Succubi, Imps, and Hellhounds in terms of Hell's hierarchy.

Description
Sinners are a large group of demons whose appearance and abilities vary widely due to their demonic forms corresponding to their human self's aspects. They are in the lower-middle levels of Hell's hierarchy, above the three lowest tiers.

Sinners have known limitations that separate them from the natural Hellborn demons; for instance, all Sinners are confined to the Pride Ring and are unable to traverse through the other rings.

Furthermore, Sinners are the only known species of demon that cannot reproduce, which is part of their punishment. Although they are the souls of dead humans, these demons are shown to still consume food and the like, which suggests that their bodies still need the intake in order to survive.

Despite these setbacks, Sinners have the rare privilege of changing their social status by gaining power, either by making deals with stronger demons and/or taking power by force. Those who have accumulated enough power through these deals can rise in social status and rise to the next class in the hierarchy, the Overlords. Furthermore, sinners are ageless and do not physically age and, therefore, will not die from the natural passage of time. Nonetheless, they can still be hurt and killed.

Appearance
There is no true extent to a Sinner's appearance, since it is the manifestation of the soul in question. Usually, a human's demon form is influenced by the human's soul, sins or crimes. An example being Angel Dust and his family: since he was in the mafia, he and his family members who are with him in Hell have spider-like appearances because of their "web" of crimes. Sometimes, the form is influenced by the human's death, such as Lyle Lipton acquiring teeth akin to that of piano keys after being crushed to death by a falling piano.

Abilities
Most, if not all, Sinners share the following traits:
 * Demon transformation - A few Sinners have demonstrated the ability to transform into larger, stronger, and more demonic alternate forms, as shown by Alastor and Killjoy.
 * Immortality - Sinners do not age and remain the same age as when they died (ex: Alastor died in his 30s, so he will remain in his 30s forever in Hell), and thus do not die of old age and other natural causes that kill humans. They also cannot die via damage to the body or from earth-borne illnesses. When a Sinner is damaged or hurt in an extreme way (ex: being crushed by a piece of rubble), they will not die from it. It has yet to be shown how the Sinner recovers; however, "Radio Killed the Video Star" has Velvette imply that, if a Sinner is completely dismembered, even by another Sinner as powerful as an Overlord, they may slowly "pull themselves back together" after some time. However, Sinners can still be killed once they are hit with any Angelic Weapons.
 * Superhuman durability - Since Sinners are already the dead souls of humans, they are highly resilient and are unharmed by most things that can harm humans. However, there are things that can injure or incapacitate a demon, Sinner or Hellborn, that being infected by Hell's own diseases and the like, or if a demon is struck by an Angelic weapon.
 * Unique abilities - Whereas Hellborn Demons have specific powers attributed to their species, Sinners are offered a larger selection of abilities that varies by individual. These range from Alastor's wide arsenal of powers, Angel's additional sets of arms, or Husk's ability to fly.

Mortality
Sinners can only be killed by angelic weapons; these are typically wielded by Exorcists.

When Sinners are fatally hit by an angelic weapon it results in the "erasure" or "final death" of the demon, and the demon's body is "killed off", while the remaining dark energy in the soul is left to wander into inanimate objects in its surroundings, which explains why some things such as regular furniture have functioning eyes.

Redemption
A rare and esoteric phenomenon, redemption is when a Sinner can ascend to Heaven and become an Angel. Because of the rarity of this event, as well as lack of information on what causes redemption, the details of this process and requirements of how to do so are not defined. Furthermore, as Sinners express an overall disinterest in attempting to change their ways, most demons and angels view the chance of redemption as impossible.

The only case of redemption occurring is with Sir Pentious; following him proclaiming his love for Cherri Bomb, he charged at Adam in his blimp to attack but was immediately vaporized by him in a self-sacrifice, and then he was sent to Heaven and became the first Sinner to be redeemed. This may suggest that in order to redeem, one has to resolve to be a better person and act selfless, however, it is unknown if the act of "selfless sacrifice" will achieve this.

Trivia

 * The creature that each Sinner is turned into when they become demons are associated with their human life, or as Vivziepop puts it, individual reflections of their souls. Because of this, their appearances are actually not randomized as many fans have speculated.
 * In some cases, the form sinners take reflects the way in which they died, such as the camp counselor shown in "Unhappy Campers" taking on an aquatic appearance due to his death from drowning in a lake (a similar case also applies to Baxter), or Lyle Lipton's demon form having teeth resembling piano keys after being crushed by a grand piano.
 * When Sinners arrive at Hell, they make up their own name that they are known for as demons. However, Alastor did not since he dislikes giving himself any sort of nickname.
 * This also holds true for business partners, Loopty Goopty and Lyle Lipton.
 * Since Demons theoretically cannot die via natural causes, such as Earth-based illnesses and overdosing, Sinners are able to consume amounts that would be lethal to humans without any risk of dying.
 * This is shown in both Angel Dust and Husk, as both are able to consume vast amounts of drugs and alcohol without any threat of death.
 * In "C.H.E.R.U.B", Blitzo was able to figure out that Loopty had just been sent to Hell recently judging by his scent from Earth, implying that Sinners retain their smell from the living world but it may eventually fade away.
 * In a development stream, artist Faustisse stated that demons can transform when enraged or when in combat. In the series, while several Sinners have demonstrated this ability, it is unknown if this is an ability all Sinners possess or is specific to certain individuals.
 * According to Faustisse, Sinners have alternate forms if ever they were sent to Heaven. However, it is unknown if this referred to humans who died and became angels instead of demons, or humans that already became Sinners.
 * The latter is the case with Sir Pentious when is sent to Heaven he gained a new form that is similar but different from that of his demon self.
 * According to Faustisse, a human's voice changes when they are transformed into Sinner demons, possibly into whatever fits proper.
 * However, this detail may have been retconned as it is not the case with Mrs. Mayberry onwards, since she and the other Sinners retained their human voices even after they went to Hell.
