Oskar von Horrificus is a little vampire that Amaya met in The School For Vampires.
Oskar is often seen as the hero and is one of the students at the school. Count von Horrificus is his uncle. Oskar tries to be a great student, but unfortunately he has a fear of blood, therefore he is a vegetarian. He is still able however to change into a vampire bat like his friends and often visits the human girl Sunshine because he has a crush on her and she feels the same. However, Sunshine doesn't know he's a vampire, as she is a skeptic, although she did turn into a vampire herself for a while. His name may be based on the character Oskar from the vampire novel and movie, Let The Right One In.
