What if your a vampire and werewolf?

Answer 1

Aside from the fact that these are fantastic creatures and not real in any way, what you are proposing is impossible. There's a reason you never hear of Vampires giving birth; because it isn't possible. The men would be infertile (their sperm would be just as dead as they are), and the women barren (same thing for eggs). Besides, think about it, a woman would have to be turned while pregnant, and if she were, since Vampires stop aging at the point they are turned, she would be in a perpetual state of pregnancy for eternity, the fetus either dead inside her, or in a perpetual fetal state, unable to be born because it is not viable.

The alternative would be to turn as woman as she is giving birth, but if the infant were still connected umbilically, then it would also be stuck in a perpetual state of infancy, just subsisting on blood rather than mother's milk.

If you aren't a parent yourself, let me assure you, even Vampires would tire of that very very quickly. Such a creature would not be long for this world.

Now, with that said, moving into the outside realms of the possible, AD&D had creatures called "Vampyres"; they were like Blade from the Marvel Universe in way. They were children born to mothers bitten while pregnant, but not turned into Vampires. They were born with most of the Vampires advantages (i.e. incredible strength, speed and agility, shapeshifting, thirst for blood), but none of the weaknesses (i.e. they were able to walk in daytime, no allergy to garlic, etc.). While pound for pound they weren't as powerful as vampires, they weren't undead (or immortal, though they did tend to live for centuries rather than decades), and they didn't sleep in coffins. With that in mind, if a Lycanthropic mother gave birth in such a fashion, her child would be fantastic indeed, though there would be no necessary advantage to shapeshifting into a wolf when the Vampyre could do that anyway. The main difference would be that unlike normal Lycanthropes, that can eat whatever they want, the vampiric one would need blood and likely live much longer. He would have the added allergy to silver and wolfsbane too, so honestly, I think it's more of a hindrance being lycanthropic than not.

Of course, this is all hypothetical, since it logically could never happen.

Answer 2

The werewolf would get fat? I don't know! Ask the werewolf that ate it!

Answer 3

There is no such thing as either one. They are myth and don't exist. So, don't worry about it.
