A creature from the forest world of Mantessa, the panthac is one of its most dangerous predators. The fierce pack animal is so deadly that several attempts to breed it offworld caused severe destruction to the native fauna of planets where it was raised.

The Galactic Empire used the panthac as the base template for the creation of the genetically modified garral. A Galactic Alliance unit, the Orange Panthacs, were named after the animal.

It also spawned the phrase "A panthac doesn't change its stripes". It's unclear whether this striped version of a panthac was a different species, sub-species, the product of the Imperials' experiments or simply just a point being made in the phrase's context.
