Quarsian

The Quarsians were aliens that specialised in constructing androids. They resembled clumsy upright walking blobs with two eyes that were on top of protruding stalks.

Their androids varied from simple 'storm trooper' soldiers, to robotic facsimile copies of people.

A group of Quarsian pirates raided the colony of Sartor, intending to plunder its diamonds to harness the powerful but bulky Zortron energy that powered their ships.(DWBIT: The Diamonds of Sartor, Quarsian Mission, Android of Death)
