Compactor droid

Compactor droid was a type of droid designed by Iokath species to tend to gardens and parks on their artifical world of Iokath. The species went extinct following the Iokath civil war and Compactor droids were repurposed by ARIES into the combat units, aggressive to any intruders.

Behind the scenes
Compactor droids appear in Star Wars: The Old Republic: Knights of the Eternal Throne as emenies on Iokath.
