Durkii

A Durkii is a giant, non-sapient reptilian biped found on the planet Tammuz-an, in a galaxy far, far away.

Biology
They are large, purple-skinned bipedal reptilianoids with a long tail and sharp claws on their hands and feet. They're known to be infected by a relatively-small species of parasites known as Kleex, which seem to be largely responsible for the Durkii's hostile behaviour. Removing the Kleex will sooth the Durkii, making it far more docile.
