- With ''VideoGame/{{Helltaker}}'' for a series of lovable, attractive demons and some of them bear similarities.

* With ''WesternAnimation/StarVsTheForcesOfEvil'' due to Charlie and Star being extremely similar in design and personality, as well as both being princesses that aim to end a longstanding status quo among their people. There's also some overlap with Tom, who's a demon that dated Star, while Charlie is a literal demon that lives in Hell.

* Due to Creator/JeremyJordan being the voice of Lucifer, numerous fans of ''WesternAnimation/TangledTheSeries'' jumped on board since Lucifer sounds and acts so similar to Varian.

* Weirdly enough, there is a lot of overlap between ''Hazbin'' fans and ''VideoGame/{{Ultrakill}}'' fans, though this can maybe be chalked up to both having large {{LGBT Fanbase}}s and prominently featuring non-standard depictions of both Heaven and Hell, though ''ULTRAKILL'' is obviously much more cynical and nihilistic with its version.

''ULTRAKILL'' fans also point out the hilarious coincidence that the [[Recap/HazbinHotelS1E1Overture first episode]] of ''Hazbin Hotel'' and ''ULTRAKILL'''s prologue are both called "Overture".

* There's also overlap with the ''Manga/JoJosBizarreAdventure'' fandom, partially because of the strong LGBT elements in both fandoms. Mick Lauer has also been involved with both shows, voicing Leone Abbacchio in Part 5/''Golden Wind'' and Husk in ''Hazbin Hotel''.

* There's also some with ''WesternAnimation/TheOwlHouse''. Both feature a quirky bi girl as the protagonist whose love interest is a moody lesbian who would do anything for their partner, and who have a friendship with a tall, insanely powerful being with an affinity for the color red, a sentient staff/cane, a NightmareFuel inducing demon form, and a distinct AnimalMotif. At least one [=DeviantArt=] artist even made a headcanon of Eda and Alastor secretly being siblings.

* With WebAnimation/TheAmazingDigitalCircus, due to being Main/BlackComedy animated web series with only the pilot out so far and having some people involved in both shows, notably Gooseworx and Creator/MichaelKovach.

* With ''VideoGame/{{Doom}}'', of all things. The most likely explanation is that both involving dealing with a glut of corrupt demons, albeit through [[AscendedDemon comically opposite]] methods. Either way, there's a lot of fanart that shows Doomguy and Charlie getting along.

* Despite the aforementioned FandomRivalry, many ''Hazbin Hotel'' fans do get along with ''Lackadaisy'' fans. Helped by the fact that some of the crew who worked on the ''Lackadaisy'' pilot also worked on ''Hazbin''.
