They're basically humans, only now horrific monstrosities and are purely predators who are really fast and have claws and sharp mouths. 

So they have everything your normal human would have, but are faster, far more ugly, and are hate filled violent monsters.

Hmm... Sounds like someone has to teach humans how to fend for themselves. 

By creating weapons.
