A half-vampire is the offspring of a human (or other species) and a vampire.
Examples of half-vampires In Billy and Mandy
Dick (human mother, vampire father)
Irwin (Part-vampire) (vampire grandfather)
Half-vampires may appear human, but, as proved in Underfist: Halloween Bash, they can turn into a bat and have traits of their non-vampire parent. It is unknown of Dick can turn into a bat.
- In Slavic folklore, a half-vampire is called a Dhampir. Unfortunately, this term is never used in the show.
