"♫ When you want somebody gone and you don't wanna wait too long, call the Immediate Murder Professionals! ♫ "
―I.M.P jingle

The Immediate Murder Professionals, abbreviated as I.M.P, is a startup assassination business within Hell. The founder/CEO is Blitzo, and their office is located in the seventh floor of a condemned company building.

The company originally operated illegally with the use of Stolas' Grimoire, but as of "The Full Moon", having received an Asmodean Crystal, are conducting business legally under Asmodeus' jurisdiction.


I.M.P was founded by Blitzo and is run by him along with his employees, consisting of fellow Imps, Moxxie and Millie, as well as his adoptive Hellhound daughter, Loona. The company offers the unique service of eliminating living targets still on Earth as a form of settling the unfinished business of Hell's residents.

This was previously done through the use of Stolas' Grimoire that opened portals to Earth, allowing the assassins access to their human targets. However, as of "The Full Moon", they now use an Asmodean Crystal that was given to Blitzo by Stolas.

While they do not accept contracts unless the targets are in the living world, they may accept special requests either if enough money is offered or they get to kill someone; an example of this is shown when Stolas hired them as bodyguards in order to safely visit Loo Loo Land with his daughter and they got to kill several would-be assassins targeting Stolas.


Blitzo has made several expensive advertising campaigns with varying degrees of effectiveness.

I.M.P Jingle

Main article: I.M.P Jingle

In the non-canon Helluva Boss pilot, a series of TV adverts prominently starring Blitzo and featuring a jingle that he wrote. Much to Moxxie's annoyance, Blitzo used up most of his employees' salaries funding it, paying for it to be run for three hours straight on an unpopular TV channel, then blamed Moxxie for the company's poor performance.


A single billboard near I.M.P Headquarters, Blitzo attempted to have it say "Got an asshole in the living world? Come to I.M.P!" with a big picture of Blitzo and a giant arrow pointing to the I.M.P office. The advertising company instead used poor-quality speech-to-text software when making it, with the billboard reading "Goat an asshole in the living worlds!? Come to I Am Pee!!!!??! Make sure you put this sign on the rite side. Don't fuck this up. Also payment may take a few weeks because it cums in the mail. SPEECH TO TEXT. Blitzo.", and pointed the arrow away from the office.

Spring Break flyer

In "Spring Broken", Blitzo made this promotional flyer during his challenge with Verosika Mayday over a parking spot, advertising a discount for contracts for that day. Despite Blitzo only creating one flyer (and Moxxie saying that the flyer contained poor spelling and bad grammar), it was proved to be wildly successful and attracted a line of customers stretching down the street.

  • The I.M.P initials form the word "Imp", which is the demon species of Blitzo, Moxxie, and Millie.
  • In "Murder Family", it is revealed that the building I.M.P operates out of is supposedly condemned.

  • The I.M.P van's front bears a slight resemblance to a 1992 GMC Vandura/Chevrolet van. The color scheme may be a reference to television series The A-Team, which also featured a black Vandura with a red stripe on both sides.
  • The I.M.P poster in "Seeing Stars" reveals that the company's phone number is 666 08432190 and that Blitzo's office safe passcode is 1234.
  • In "Exes and Oohs", Blitzo reveals on his phone call with Crimson that I.M.P used to be for-hire for killing targets in Hell[1] as well, but no longer do this for reasons currently unknown.
  • In the French version of the non-canon Helluva Boss pilot, I.M.P is translated to "Infâmes Meurtriers Professionnels", which roughly means "Odious Professionals Murderers".
  • As revealed by Moxxie in "Unhappy Campers", the company usually does not do investigations of the client's murder, most likely because it was the first time they've ever had a client with no knowledge of their killer. All clients prior to the episode have always had photos or stories to tell of the contracts in need of fulfilling.
  • Now that Blitzo has an Asmodean Crystal in his possession, this means that I.M.P. is no longer an illegal organization in Hell. However, this also means that the company could be shut down if Asmodeus ever decides to take back the crystal since the company is now legally under his jurisdiction.
