Sinners

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

Description
There's no true extent to a Sinner's appearance, since it mostly is made based on the soul in question. Usually, a human's demon form is influenced by the humans 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 are spider demons, because of their 'web' of crimes. Sometimes, it's influenced by the human's death. Fans theorize this via Niffty's shirt, which has red dots that resemble bleeding gunshot wounds or Tom Trench, who has a gas mask on his face since he could've died from mustard gas poisoning in World War 1.

Abilities
Most, if not all, Sinner Demons share the following traits:
 * Demon Transformation: Some demons have demonstrated the ability to transform into larger, stronger, and more demonic alternate forms. According to artist Faustisse, all demons can transform when enraged or when in combat.
 * Summoning: Demons have the ability to summon elements, objects, and even assistance one way or another. Examples of this are Alastor being able to summon an army of shadow creatures and Charlie being able to summon fire out of the palm of her hand.
 * Longevity: Demons do not age, and thus do not die of old age and most of the other natural causes that kill humans. However, they can still be killed once they are hit with any of the Exorcists' weapons or if they have been infected by Hell's own diseases and the like.
 * Unique Abilities: Demons have a wide range of abilities that are exclusive to certain demon types or individual demons. These range from Alastor's wide range of powers, Angel's ability to sense storms and jump really high, or Husk's ability to fly.

As mentioned before by Vivziepop, Sinners cannot reproduce, although Hellborns can. In the case of Charlie, her birth is yet to be explained as Lucifer is the only known Fallen Angel in a relationship with Lilith, a demon.

Trivia

 * The creature that each Sinner is turned into when they become demons are associated with their human life, or as Viv puts it, individual reflections of their souls. Because of this, their appearances are actually not randomized as many fans have speculated.
 * An example is how there's a reason why Angel's family in Hell all take the form of spiders—they are a "web" of organized crime.
 * When Sinners arrive at Hell, they make up their own name that they are known for as demons. However, Alastor is excluded since he dislikes giving himself any sort of nickname.
 * Once a demon dies in Hell, the dark energy within them wanders off and possesses random everyday inanimate objects such as furniture and tools, which explains why some of the things seen in the background and such have functioning eyes.
 * Since demons theoretically can not die via natural causes, such as illnesses and overdosing, they 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.
 * This does not mean, however, that there are no negative side effects, as Loona makes clear demons can still get hangovers.
 * According to Vivziepop:
 * Demons have alternate forms if ever they were sent to Heaven.
 * The Sinners have different voices as humans before they were transformed into demons.
 * Despite this being said, it is not the case with Mrs. Mayberry, who retained her human voice even after she went to Hell.
 * It is revealed in “C.H.E.R.U.B.” that sinners have a different smell from Hellborn Demons, as Blitzo was able to figure out that Loopty had just been sent to Hell recently judging by his scent.
