The Shapeshifters are mostly a hostile species, and they were discovered in the medieval times. They are like 9.2 inches tall. What did you expect? And that's not the scary part. The scary part is that they can also run extremely fast (faster than a cheetah). And as the name "Shapeshifter" suggests, they can shape shift into ANYTHING. You heard me. ANYTHING. Trees. Rocks. Even Tarantula Hawk Wasps. And they also mimic voices to lure in their prey.
You're probably wondering: "What does a Shapeshifter eat?" That's pretty easy to answer. It eats EVERY SINGLE LIVING THING. Cats. Dogs. Moose. And even Spiders. But it's most preferred meal is Humans. And that is a bad thing, because not a single person survived when facing a hostile flesh eater that can shape shift.
