Imps

Imps are a species of Hellborn demons that have the lowest ranking in Hell's hierarchy.

Description
Imps are in essence the "working-class" of Hell’s society. They have lowest ranking demons in Hell's hierarchy and therefore the least respected and most likely to be hired for slave work or as servants. There is a hotspot in Hell for imps called Imp City, which appears extremely shabby and filled with homelessness even by Hell's standards.

Appearance
Imps are designed to look like how the devil is typically portrayed in media, with horns and an arrow-shaped tail. Their color schemes simply consist of primarily red skin, with additions of details, markings, stripes and blotches in black and white providing strong contrasts. Their eyes have prominent yellow scleras that glow in the dark, black slit pupils, and sometimes visible red irises.

They come in a variety of shapes and sizes, although the most common ones appear to be around the same height as an average human adult, but with many of them being significantly shorter. One of the most distinctive traits that tell them apart is the shape of their horns, which can vary greatly from individual to individual. Imp blood is usually shown to be black. Female imps are shown to usually have mostly dark hair whereas male imps are shown to have mostly white hair, although there are apparent exceptions, such as a male imp with dark hair that can be seen in the backgrounds of the episode "Loo Loo Land". In Blitzo and his sister, Barbie Wire's case, they would be considered bald.

Imp heads are relatively large compared to their bodies, and have some vaguely reptilian traits, such a lack of ears, lack of defined noses, and their heads often have a slight conical pointiness towards the upper lip. Imp head shape varies notably, such as Blitzo and Barbie Wire having elongated rear craniums. Although they usually appear to lack any nostrils at all, giving the middle of their face a bare, alien look, they are revealed to actually have nostrils when actively smelling something. Their teeth are usually shown as sharp and conical, and their tongues are forked like those of snakes.

Imps arms and legs have some amount of variation, they may have either plantigrade or digigrade feet, often with hooves or claws, which are usually black. Blitzo is even shown to have natural high heels on his feet. Both Blitzo and Barbie Wire have wrists and ankles which are relatively thick and undefined.

Abilities

 * Photokinesis: Imps have the ability to project light from their eyes when they are in dimly lit areas.
 * Pyrokinesis: At least some imps are capable of producing flames, such as the Imp carnie in "Loo Loo Land", who lights a cigarette made from a bill with a flick of his finger.
 * Fire Resistance: As shown in "Murder Family", Imps are immune to fire and being fully engulfed in flames does not harm them. It is unknown if this is an ability unique to imps or if it is a trait all demons possess.
 * Flight: Some, but not all, Imps are born with wings behind their backs, which grants them the ability to fly.
 * Unique Abilities: Although more of it has yet to be shown, Imps have a wide array of abilities that is unique to individual Imps. An example of this is Blitzo's ability to purr.

Mortality
Unlike sinners, it appears in the episode "Loo Loo Land" that Imps can be affected by non-Exorcist weapons. It is unknown if this truly kills them or simply incapacitates them, but it implies that Hellborn demons can be fatally injured if enough damage is applied.

Trivia

 * In mythology, imps are minor types of fairies or demons that are typically more mischievous than threatening, and as such are deemed lesser beings, even servile, to supernatural entities.
 * In the episode "Murder Family", Blitzo is injured by a bullet while in the human world and later implies that a shot to the head would send them back to Hell. This statement appears true based on Millie's reaction but is never outright confirmed or denied on-screen.
 * It is possible that young imps are called "implings", as Robo Fizz addresses them as "implings" in his show.
 * Imps look very stereotypically demonic. It is unknown if imps before I.M.P have interacted with humanity before.
 * In the episode "Murder Family", Blitzo is injured by a bullet and bleeds, which shows that Imps have black blood.
 * Some Imps are revealed to be able to have wings.
 * Imps are one of the main targets of the Exorcists, alongside Sinners.
