Personality[]
Klaus enjoys getting the better of his first cousin, Mavis, whenever they are together and can be a bit of a bully towards her and her friends at the hotel. He really hates it when monsters get his name wrong and whenever Mavis gets the better of him, like when Mavis got him to fall on his face during a high-five moment when they were young; and he had started to plan his revenge to get her back.

In "The Mavysitters Club" he reveals he was trapped five years in a cave of werewolves where he learned their ways due to nobody rescuing him.
He appears to be forgetful, as he seems to have forgotten that Mavis taught him how to bat out "last year" when falling into a bottomless pit. His role model is Mavis’s father, Count Dracula. He is also thought as a annoying person by everyone except himself.
