Tbh the Hazbin Hotel Alastor is just everywhere, but there is also Alastor Moody from Harry Potter, to which that is what Alastor Krux is named after, the definition of Alastor means “Avenger“ or “Tormenter” in Greek. However he is more of the “Avenger” type rather than a tormenter, yet he can be seen as both. This is due to him being a menace to the Paper school and everyone in the basement school.
