Octuptarra tri-droid

The octuptarra tri-droid, also known simply as the octuptarra droid or tri-droid and nicknamed the "virus droid" due to the biological plagues it sometimes carried, was a model of three-legged droid walker manufactured by the Techno Union. Produced in a number of different sizes, including agile octuptarra combat tri-droids and gigantic octuptarra magna tri-droids, they were used by the Confederacy of Independent Systems during the Clone Wars.
