Imps

Imps are a species of Demons native to hell that have the lowest ranking in Hell's hierarchy.

Description
Imps are the 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 homeless even by Hell's standards.

Known Imps

 * Blitzo
 * Moxxie
 * Millie
 * Tilla
 * Barbie Wire
 * Blitzo's dad
 * Moxxie's parents
 * Millie's parents
 * Millie's siblings
 * Stolas' servant

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 black, red, white and bits of yellow. 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 have black hair whereas male imps are shown to have white hair. In Blitzo and his sister, Barbie Wire’s case, they would be considered bald.

Abilities

 * Demon Transformation: Imps possess a common trait that is shared amongst every species of Demons, which is the ability to transform from their default forms to their full Demon forms at will.
 * 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 some flames, as is the imp holding a post in Loo Loo Land, who lights a cigarette made with 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 posses.
 * 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 former humans in hell it appears in the episode "Loo-Loo Land" that Imps can be killed with non-exterminator weapons. It is unknown if this truly kills them or simply incapacitates them but it implies that hellborn demons can die 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.
