Vampire (Marvel Comics)

Vampires (''Homines nocturnae'') are fictional characters appearing in American comic books published by Marvel Comics. The concept of the vampire has been depicted by Marvel to varying degrees of significance. Bearing a strong resemblance to their literary counterparts, Marvel vampires are mostly an undead species of humans that sustain their immortality and paranormal power by drinking the blood of living humans. Unlike most other depictions of the creature, these vampires have their roots in both the supernatural and biology. Victims are converted to vampirism via enzymes carried in the vampire's saliva, which cause reanimation once introduced into the bloodstream during feedings. Provided by Wikipedia
