Amphi-Hydrus
From Wookieepedia, the Star Wars wiki.
The Amphi-Hydrus were a race of amphibious beings native to the water-planet Dac, commonly referred to as Mon Calamari. They were small, physically weak creatures, but were masters of mind control, using the powers of the dark side of the Force to manipulate others into doing their bidding. Shortly before the subjugation of the planet by the Galactic Empire, they gained a foothold of the entire planet by telepathically controlling a few rancors which had been imported to the planet. They were seen on the back of these monstrous beasts, riding them and wreaking havoc wherever they went. However, when the Galactic Empire attacked, this all came to an end and so the Amphi-Hydruses simply became swamp dwellers, and bitterly awaited the chance to recapture their previous power.
[edit] Behind the scenes
The Amphi-Hydrus was created by Daren Horley, a Star Wars fan, as part of the Design An Alien contest held in the Star Wars Galaxy Magazines. Though the entry was not picked as a winner, it was given an honorable mention in Star Wars Galaxy 7.
Their appearance and mind controlling abilities bear a startling resemblance to that of the Dnyarri from the game Star Control II.
