Huduct

The Huducts are a sapient species from an unknown planet, which developed mind-controlling torcs that could turn other creatures into slaves.

Biology
They're mammalianoid bipeds with purple skin and red eyes.

History
For thousands of years, the Huducts have used their torcs to enslave the Anubians, until the robotic dog K9 liberated the Anubians from their masters. When K9 left the planet, he believed that the Anubians and the Huducts would be able to reconcile and live in peace. Unfortunately, what happened instead was that the Anubians managed to reverse-engineer the torcs and used them to enslave the Huducts and numerous other species.
