Scour swarm droid

Scour swarm droid was a type of droid designed by Iokath species to clean the Chromium Garden on their artifical world of Iokath. The species went extinct following the Iokath civil war and Scour swarm droids were repurposed by ARIES into the combat units, aggressive to any intruders.

Behind the scenes
