* AssholeVictim: ZigZagged. ''Sometimes'', the targets of I.M.P. usually turn out to be pretty nasty pieces of work, so you don't feel bad when they meet brutal ends courtesy of the demonic assassins. But other times they can be completely innocent or decent enough people that they take out solely because a client asked for it. The latter is scene especially in "[[Recap/HelluvaBossS1E3SpringBroken Spring Broken]]" where they slaughter multiple innocent people whose worst crime is just excessive partying simply to win a parking spot.

* OhMyGods: A drunk Moxxie in "Spring Broken" and a sober Blitzo in "C.H.E.R.U.B". Both use the name of Satan in variants of swears that normally invoke God, such as "Oh Satan" instead of "God Damn" and "Satan's Balls" instead of "Jesus Christ".

* OurImpsAreDifferent: Imps are the lowest class of demons in Hell, and are not really treated well by many higher-class demons, often being used as servants for higher demons.
** As a race, imps are physically very diverse, an example being their legs, as aside from normal ones they can have goat-like legs. "WESTERN ENERGY" shows that imps can be so small that they can be carried in a purse and need to hold a teapot over their head.
*** SecondarySexualCharacteristics are also present, both in hair color and horn markings. Female imps have black hair as opposed to white for males. Horn-wise, females have predominantly black horns with thin white stripes, while males have black-and-white stripes of similar thickness.
*** Additionally, it is possible for imps to have wings for flight.
*** Uniquely, imps are implied to heal differently from other demons, with scar tissue becoming white marks upon their skin.
*** Imps also seem to have some abilities related to fire. In "Murder Family", Millie and Blitzo proved impervious to normal fire, i.e. non-infernal flames, when Martha tried to burn them on a stake. Additionally, one imp in "Loo Loo Land" showed the ability to produce a small fire from his fingers.
*** Imps also come in a variety of size, from about a head shorter than the average adult human height, to a few inches tall.
