Farakosh

From Tardis Wiki, the free Doctor Who reference

The Farakosh were a telepathic species who lived on a planet that had been colonised by humans. One of those humans, Paula Taylor, called them the "top of the food chain" on the planet, until humans arrived. When the humans started building telepathic fields to control their Exotron robots, it began to harm the Farakoshes' telepathic senses. They then attacked the Exotrons.

Peri described them as resembling hyenas. (AUDIO: Exotron)
