Do you believe in the supernatural?
~ Maximillian to Detective Rita Veder in Vampire in Brooklyn

Supernatural is a category for strange entities and paradoxes that defy our currently-accepted laws of science or reason, yet cannot be easily classified into traditional roles such as ghosts, demons, angels, or undead.

Common examples of supernatural villains would be extra-dimensional beings or individuals with unexplained powers that cannot be explained by mutation or orthodox magic.

NOT to be confused with "Supernatural Villains," which details villains from the CW TV show.
