Okay a few people have asked me...
"What would happen if a vampire bites a werewolf...
or if a werewolf bites a vampire?"
Here is what I think:
Nothing at all. It's that simple. Both the lycanthrope and vampire are known to have immunity to disease. And I think they would cancel the other out.
Now let's explore a question I have wondered,
"What if a human were to get bitten by both a vampire and a werewolf at the same time. Which would you turn into?"
Here is what I think:
Say, you are standing there helplessly while a werewolf is biting on one arm and a vampire is biting on the other.
It might depend on who is on the left side of your body. Because your heart is on the left side, it's easy to assume the blood will be pumping faster on that side and it will spread the disease/virus/contagium faster, and take over your body faster than the disease/virus/contagium on your right.
More likely I think that the lycanthrope disease/virus would overcome the vampire disease/virus. While both are said to have an immunity to each other, it would take much longer for the vampire disease/virus to take over the human body... you have to go through the process of dying first... after all, that is why they are called the Undead.
To become a werewolf is another story. You get bitten, and you are still alive, still human, just with the side effect of being furry and wild 1-3 days a month.
What do you think?
