Vorshagg

The Vorshagg were tall, thickly built lizards with serrated teeth and dagger-like horns. Their home planet was also called Vorshagg.

History
The Vorshagg evolved to be gratuitously violent, slaughtering other life-forms on sight, but without malice. The development of the de-aggrifier, which could be affixed to the left frontal lobe of the Voshagg brain, rendered them harmless, since although the violent instinct remained, they were unable to act upon it. Following the development of the de-aggrifier, Vorshagg ambassadors were able to forge relations with other worlds, and the Vorshagg were eventually inducted into the Galactic Council. During the induction ceremony, a malfunction of the de-aggrifier of the Vorshagg diplomat caused it to eat the delegate from Largolan Beta. (PROSE: The Tomorrow Windows)

A Vorshagg criminal, who carried a weapon despite having a de-aggrifier, was present on Earth in the early 21st century. He was at the Nocturne, a bar frequented by aliens illegally staying on Earth, when Tasha Williams visited it to try and figure out more about the upcoming perihelion. He was sitting next to a Gonzie whose clothes were coated in blood. Despite the pair's fearsome appearance, the Vorshagg quickly pointed Tasha to Alinquos, a Ferrux, who was able to help her.
