Vampires
Vampires and Werewolves have been linked rivals for ever, but the real question is; which is better?
vampires never show signs of aging and will appear to stay the same age they were when turned into a vampire.

Vampires pale skin most likely stems from the diseases vampirism was mistaken for as many cause paleness to the skin or the appearance of being malnourished
Vampires will lure in their pray with outstanding charisma. They are usually depicted as males who would woo women with their sexual prowess.
People may have linked vampires with bats and other animals due to the way different illnesses would cause humans to act. In the instance of rabies, humans and animals would act very similarly when near the final stages. It isn’t a huge leap in logic to see an animal and human act the same and link the two.

Werewolves age at an extremely slow rate compared to regular humans. They can for live hundreds of years.

An interesting way to become a werewolf is to drink rain water out of the pawprint of a wolf under the full moon.
