Exorcists

The Exterminators are Angels that are sent from Heaven to kill a portion of Hell's population due to its overpopulation. They are the overarching antagonists in Hazbin Hotel.

Trivia

 * According to Vivziepop, only The Exterminators can really and truly kill the citizens of Hell using their special tools.
 * When asked why there is a reason that The Exterminators and presumably other Angels are robotic, Vivziepop said that she can't say much, but she did confirm that they're not exactly robots. However, they do wear LED screen masks on their faces.
