Alien Bone Crushers

They captured a thinly populated human world and televised hunting, killing the people with their fangs, and eating the humans.

Evolved from something foul like an Earth hyena, the savage Vilerres think they can scare off the humans, twelve thinly populated planets, and a dozen worlds with outpost settlements. Outnumbered two-to-one, the humans attack them ferociously. This vicious war to the death gets horrible very fast.
