Humans

"Humans are full of secret nasties, it's why so many of them end up [in Hell]"

- Millie, describing humans

Humans are a sapient species native to the planet Earth. Deceased human souls make up the sinner category of demons in Hell.

Description
The primary life form on Earth, humans are the only known sapient species to live on Earth, and subsequently the known universe.

Upon death, human souls traverse to either Heaven or Hell, depending on the actions that human's soul took while on Earth.

Human society as a whole is entirely unaware of the true nature of the afterlife, Heaven or Hell. However, throughout Earth's history, the entities of these realms have traveled to Earth and interacted with humans for various reasons, such as business, ritual, pleasure, or more widescale affairs. Humans are often exploited by demons, such as the Succubi species, who use humans to spread sexual activity, but otherwise remain in the dark about these beings. Some fringe groups, such as D.H.O.R.K.S., claim knowledge of the afterlife and Hell. These groups, however, are typically dismissed by most humans.

While humans possess no method or technology to transfer their physical bodies to Hell, they can survive in Hell's atmosphere unsupported, as witnessed by Eddie during his short stay in Hell. There are no native human populations in Hell.

Trivia

 * According to Faustisse, sinners have different voices before their deaths, although this does not seem to be the case with Mrs. Mayberry. It is possible that this information has been retconned.
 * In the Helluva Boss episode "Murder Family", Martha and her family seem to temporarily take on certain "demonic" traits such as sharp teeth, red eyes and slit pupils when in a state of evil derangement; these traits vanish as the situation de-escalates. It is unclear if this was a tendency unique to humans such as them, given that they were worshipers of evil forces. The appearance of these traits are likely meant as visual metaphors, and not literal transformations.
