Hmmmmm......perhaps if everything in this thread is taken into account we may end up with something very unvampirish. It'd likely be a new mythical creature.
*GASP!* The horrors!
I think if we took everything in this thread into account, we'd end up creating the Unbeatable Monster from AW Hell. It couldn't have an supernatural powers that weren't scientifically explainable, but at the same time, you couldn't explain its exsistence using science. It would burn up in the sun, but only if it forgot to chomp down a humanburger the night before. It would have crazy lecherous tendencies, but would see humans as basically a foodsource. It would have a secret hoard of cash somewhere. It would be superhot, but at the same time (maybe in sunlight?) it would be green and fuzzy. Plus holy relics wouldn't have any effect, stakes are negligible, and it's apparently addicted to our blood.
Apparently sporks would be the only plausible weapon, but since it's so superpowerful and all, it would probably go on a spork-smashing raid and destroy all threats to its power.
OMG, WHAT HAVE WE CREATED?!
We'd never be able to kill the thing off! It would just go around sucking up people until the world came to an end! AHHHH! I'm with dgiharris. Let's get the heck out of dodge!! RUN FOR YOUR LIVES!
But since we just made it up, it would probably be considered mythical in another 200 years or so.
meh, I'd be okay with that. Some historian would trace it back to this thread and give everyone posted here credit. We'd have a one-liner in some future kid's history textbook.
(whoa. Try wrapping your head around that last sentence @_@)
