The Ultimate Vampire Resource and Directory

The Thing has gone through some interesting evolution from its original story, "Who Goes There?" In Who Goes There?, 30+ men working at a Cosmic Ray facility in the Antarctic discover, well, a thing. And that thing is part disease, part animal, part predator. It's a mimic that can replicate any form. And it has a desire to propagate. If it escapes from the facilities in the frozen wasteland, it will spread to humanity and ultimately take over every living thing in the world, all of them part of the original creature.
